What Are the Different Types of Sandblasting Rooms?

The sand blasting room is composed of seven systems: control, lighting, dust removal, work operation room, workpiece conveyance, sand blasting, and abrasive recovery. And it is an ideal place for removing rust on the surface of steel structures, welding parts and casting workpieces. The sand blasting system is fully automated, which solves the dust generated by the blasting machine during operation and effectively prevents environmental pollution. Common sand blasting rooms are made of brick walls, and have better water resistance and shock resistance. The blasting room is protected by wear-resistant rubber, which can effectively protect other facilities in the room. A steel grid is laid on the floor of the blasting room to prevent the accumulation of abrasives on the operating platform, which poses a threat to the safety of the blasting workers. A steel mesh is laid on the abrasive recovery bucket to prevent debris from entering the shot peening system. There are safety doors on both sides of the blasting room, which can effectively improve the safety of the workers, and if the blasting workers are in danger, they can meet their escape needs. There are observation windows in the blasting room to keep abreast of the progress of the blasting operation.

Sandblasting Room Information Collection

1. First of all, for safety and fire protection, materials should meet the requirements of safety and fire protection when selecting materials.

2. In order to easily remove the dust on the surface of the inner wall of the room, it is generally suitable to use plastic plates and ceramic tiles, which also have insulation properties. In addition, wax paper can be pasted on the inner wall, or water curtain can be used.

3. The blasting room must have a certain strength and stiffness, and a small ventilation device can be installed on the top. As for the large-scale ventilation device, a metal frame should be installed separately, and it should not be connected with the frame of the chamber body to avoid the influence of the vibration of the ventilation device. ^[1]

According to the type of airflow organization in the blasting room: the airflow organization is generated due to the ventilation in the blasting room, so that the spray flows according to the flow direction of the airflow organization. The direction where the flow direction is perpendicular to the workpiece rotation direction is called the horizontal air blasting room; the direction parallel to the workpiece's moving direction is called the vertical air blasting room; the air blowing from the top of the sand blasting room and the bottom is called up and down Back to the blasting room.

Sort by sprayed coating. There are primer blasting room and top blasting room, or other special requirements. Due to the different coating effects, the process conditions of the sand blasting room are significantly different and are also related to the selection of paint materials.

Classified according to the structure of the sand blasting room. Mainly due to the different spray filtration methods, there are dry blasting rooms, which use baffles or filters to capture and process spray. Wet blasting rooms rely on water treatment sprays. In addition, there is an open blasting room, which means that there is no fence structure around the workpiece.

1. Sand blasting personnel should wear sand clothes, or canvas overalls, dust-proof protective masks, high-top sneakers, and canvas gloves.

This system realizes the centralized control of the blasting room cleaning room. This system uses a programmable logic controller (PLC) as the core and uses high-quality electrical components. It has many advantages such as reliable work, high degree of automation, and complete protection functions.

The main power of this system uses 3-phase 380v AC power, and the control circuit uses single-phase 220v AC power. The control transformer reduces the 380v voltage to 220v and uses it for the control circuit. In order to reduce interference, the PLC's working power is powered by a separate transformer.

This system has a relatively complete fault alarm function, helping operators or maintenance personnel to quickly find the fault point, reducing downtime and improving work efficiency.

The electrical components of this system are centrally installed in electrical cabinets and operation consoles, and use a human-machine interface touch screen for easy operation and maintenance.

Imported PLC + touch screen control, with automatic / manual control functions.

In order to simplify the equipment, the two parts of abrasive recovery and ventilation and dust removal can be combined. The fan sucks all the abrasive, dust, and airflow through the honeycomb floor to the abrasive centralized filter. The dust-containing gas is filtered by the filter, the dust is attached to the outer wall of the filter, and the clean gas is discharged through the filter to the outside of the plant, and part of it is circulated to the blasting room. The abrasive and heavy dust continue to pass through the abrasive tank to the sorter. The sorter has an inner and outer cone structure with an adjustable channel between the inner and outer cones. By adjusting the core body, the cross section of the air flow channel can be changed, thereby adjusting the separation ratio. The separation process is: When the abrasive and dust pass through the channel, due to the effect of gravity, the dust and gas come out through the gap between the cones, and the abrasive and coarse particles fall to the vibrating screen below the cone. The vibrating screen further separates the abrasive and coarse particles, and the separated pure abrasive enters the designated hopper through the sieve holes to the blasting tank for recycling. The dust and gas passing through the separator are filtered by a filter, the clean gas is discharged outside the plant, and the dust falls into the waste hopper.

The blasting room is designed according to the manufacturer's own product processing process and product characteristics. It is mainly used for surface descaling and rust removal of large castings, industrial boilers, shipbuilding, engineering machinery, etc., further improving the base coating Focus.
