Mixed basic meaning

Mixer 1. [Industry]: Generally refers to the operation of mechanically dispersing two or more materials to each other to achieve a uniform state. Used to accelerate heat, mass and chemical reactions (such as nitrification, sulfonation, saponification, etc.). It is also used to promote physical changes and make many mixtures, such as solutions, emulsions, suspensions, mixtures, etc. It can be performed in a mixer or the like.

2. [Photography]: It is a picture of two video signal input sources. It is a basic switching method in the switching process. Blending is also called slow switching. It refers to the blending transition of pictures. One picture slowly disappears and the other picture slowly appears, or two pictures overlap. It can be divided into two ways: one is to transform Fading in, the other is fading in and out. The so-called fading in and out refers to the gradual weakening of one picture until all disappear, and the other picture gradually strengthens to a normal state. , Another picture gradually emerged from weak to strong, the two always superimposed until the latter completely replaced the former.

3. [Law]: refers to the fusion of movable property of different owners. Including solid and solid mixing, liquid and liquid mixing and gas and gas mixing. If the mixture cannot be identified, or if the identification does not meet the economic rationality principle, it belongs to the party with the higher value of ownership or shares. The party with a higher value alone shall compensate the other party.

Hybrid overview

Mechanical or hydrodynamic methods are used to make two or more materials disperse each other to achieve a uniform unit operation. Where fluid materials are involved, it is a hydrodynamic process. The application of mixing in chemical production is very common. The main purposes are: to prepare various homogeneous mixtures, such as solutions, emulsions, suspensions, and slurry, paste or solid powder mixtures; for some units Operation (such as extraction, adsorption, heat exchange, etc.) or chemical reaction process provides good conditions. When preparing a homogeneous mixture, the mixing effect is measured by the degree of mixing of the mixture, that is, the uniformity achieved. When accelerating the physical or chemical process, the mixing effect is usually measured by the total mass transfer coefficient, heat transfer coefficient, or the extent to which the reaction rate increases.

The so-called mixing means that under the action of external force, various material components are blended with each other, and the particles of various components are uniformly distributed in any volume. It is an important link to ensure the quality of materials and improve the effect of materials. There are various mixing methods, such as mechanical mixing, pneumatic mixing, impulse mixing, etc. Among them, mechanical mixing is more common ^[2] .

The application of mixing in food production is very common, and its main purposes are: to prepare various homogeneous mixtures, such as solutions, emulsions, suspensions, and paste, paste or solid powder mixtures; for some units Operation (such as extraction, adsorption, heat exchange, etc.) or chemical reaction process provides good conditions. When preparing a homogeneous mixture, the mixing effect is measured by the degree of mixing of the mixture, that is, the uniformity achieved. When accelerating the physical or chemical process, the mixing effect is usually measured by the total mass transfer coefficient, heat transfer coefficient, or the extent to which the reaction rate increases.

Mixing process

Taking mechanical stirring and mixing as an example, the mixing process can be divided into three stages: first, the convective mixing formed by the movement of small pieces of bulk materials is mainly used, and the uniformity of the mixing is rapidly improved; second, the particles slide and impact each other, or Compression and extensional shear between the paddle and the wall, the mixing speed is stable; third, the diffusion and separation of particle position exchange reach an equilibrium state, that is, the mixing uniformity remains stable or fluctuates slightly. It usually takes 2 to 6 minutes to complete the above process, but different mixers have different time requirements for uniform mixing. In particular, a longer mixing time is required for the production of pre-mixed feed, which is generally 15-20 minutes ^[2] .

Mixed mixed scale

mixing Refers to the spatial extent in which mixing occurs. For the mixing of liquid systems, macro mixing refers to the mixing of fluids on the macro scale, which is caused by the macro flow of the fluid. It includes the mixing caused by the shear force in the equipment due to the overall flow, turbulent pulsation and velocity gradient. Micromixing refers to the alternate arrangement or separation of two substances on the molecular scale, which can only be achieved by molecular diffusion. Different production processes have different requirements for the mixing scale: for example, the stirring of crude oil in large oil tanks in an oil refinery requires only macroscopic uniform mixing; the rapid reaction between two fluids requires not only macroscopic uniformity, but also microscopic Mix quickly.

Mixing degree

A measure of the degree of uniformity of dispersion and blending achieved by different materials after mixing. The degree of mixing is related to the scales examined. In order to evaluate and compare different mixing methods and mixing equipment, an appropriate expression can be selected according to the specific situation.

The degree of mixing of the fluid system can be expressed in the following three ways:

The uniformity system is a measure of the uniformity within the size of the device as a whole. The average uniformity I of a component is the arithmetic average of the uniformity of a component obtained from several samples in the same tank. It can be used to measure the overall mixing effect of the system, but the number of samples taken must be specified.

A measure of the size of dispersed micelles (such as droplets, bubbles, or solid particles) in a separate-scale mixture. Within a separate scale, the substance is homogeneous or has only one substance. The smaller the separation scale, the more uniform the mixing. For immiscible systems, it is not possible to achieve molecular-scale separations.

A measure of the uniformity of the separation strength miscible system on a small scale. During the mixing operation, different sizes and concentrations of the micelles were present in the mixture. The difference between the micelle concentration and the average concentration of these mixtures is the separation strength. The smaller the separation strength, the more the materials are mixed and the interface between the micelles is more blurred. When the mixed material has reached the ideal mixing state through molecular diffusion, that is, when the so-called molecular-scale uniformity is reached, the separation strength is zero.

In mixing equipment, the overall flow of fluid is to improve the uniformity of the mixture system, while turbulent pulsation reduces the separation scale and separation intensity.

The degree of mixing of the solid system is expressed by the standard deviation of the content of a component in the sample taken.

Hybrid approach

According to the phase state of the material being mixed, the mixing methods are:

Blending: Mix two or more powdery solid materials by mechanical method. The machine used is called a blender, which is an empty tube asymmetric to the axis of rotation, and the material is tossed and thrown in the tube. The rotation speed of the cylinder and the filling rate of the material (the ratio of the volume of the material to the total volume of the cylinder) are important operating parameters that affect the mixing effect and can be determined by experiments. The filling rate is generally about 30% to 50%, and the appropriate speed is determined by 2R / g = 0.25 0.8 (where is the angular velocity, R is the maximum rotation radius of the cylinder, and g is the acceleration of gravity). Blending is commonly used in the mixing of various raw materials and starch, the toning of dyes or pigments, and the mixing of different types of synthetic resins.

Knead and mix pasty or high viscosity materials by mechanical methods. The machine used is called a kneader. There are usually a pair of Z-type or S-type scrapers that rotate in the opposite direction, which cuts, squeezes and folds the agglomerate material to disperse the various components. During the kneading process, viscous friction or the accompanying chemical reaction causes the machine to generate heat, which needs to be cooled through the partition wall. Kneading is commonly used in the formulation of pharmaceutical dosage forms, food materials and electrode pastes.

Mixing refers to the operation of mixing carbon black, sulfur and other powdery granules in raw rubber. The machine used is a sealed mixer, also known as a mixer. The machine is equipped with a pair of cylindrical rolls, which have two or four spiral ridges. The two rollers rotate in opposite directions at different speeds, and the materials are cut and divided strongly. There is a cooling device inside the machine to remove the heat generated by the friction of the materials.

Stirring is the most commonly used method to disperse liquid, gas or solid powder particles into a liquid.

Jet mixing uses the energy of the working fluid itself to mix during its flow. The working fluid is ejected at high speed from a circular nozzle or a tapered nozzle to form a jet. Due to the turbulent pulsation at the interface between the jet and the surrounding fluid, the two fluids are mixed. Jet mixing is mainly used for mixing low-viscosity liquids in large containers in the industry, such as adding a small amount of tetraethyl lead in large gasoline tanks, and also to prevent the deposition of solid suspended solids in the tank. Sweep the precipitate and let it suspend.

Pipe mixing uses a three-way pipe to combine the two fluids, and then flows through a straight pipe to achieve mutual mixing by turbulent pulsation. Adding a perforated plate or a round baffle in the tube can strengthen the turbulence of the fluid and improve the mixing effect. This method is mainly used for mixing low viscosity liquids or gases. A static mixer is a pipe mixing device. A static dividing element is arranged in the tube to divide and merge the flowing fluid multiple times. This mixer is not limited to turbulent operation, but also suitable for mixing high viscosity liquids in laminar operation. A typical static mixer (see picture) is a set of several helical blades twisted 180 ° in a circular tube as components, and the two types of helical blades, left and right, are installed in phase. Every time a fluid flows through a spiral sheet, it is divided into two strands and flows through n elements, and the fluid is divided and merged 2n times. If there are 20 elements in the tube, the fluid will be divided more than 1 million times. Static mixers are commonly used for extraction and emulsion preparation.

Mixed classification

Mixing is generally divided into batch mixing and continuous mixing.

Mixed batch mixing

That is, the various material components are prepared into a certain number of batches according to the proportion of the formula, and the batches of materials are sent to the gap mixer for batch mixing. Mixing for one cycle produces one batch of material. This mixing can quickly change the proportion and variety of ingredients, and it is more convenient to change batches. There is less mixing between each batch, but the operation is more frequent.

Continuous mixing

That is, the various material components are continuously measured separately and continuously fed into a continuous mixer or corresponding mixing equipment for mixing. This process is suitable for relatively fixed production of materials of a certain variety and formula. It is troublesome to change batches, and due to the large amount of residual materials, the intermixing of the two batches is heavy.
