Sandblasting room

Sand blasting room is generally used for spraying and baking car paint. Therefore, the most appropriate description of sand blasting room should be "sand spraying room". When baking paint, adjust the air door to the position of baking paint, the hot air circulates, and the temperature in the baking room rapidly rises to the predetermined drying temperature (55 ℃ - 60 ℃). After the external fresh air is preliminarily filtered by the fan, it is sent to the air chamber on the top of the sandblasting room after heat exchange with the heat energy converter, and then it is purified by the second filtration. The hot air is recycled through the inner circulation of the air door. In addition to a small amount of fresh air, most of the hot air is inherited and used for heating, which makes the temperature in the sandblasting room gradually increase. When the temperature reaches the set temperature, the burner will stop automatically; when the temperature drops to the set temperature, the fan and burner will turn on automatically to keep the temperature in the sandblasting room relatively constant. Finally, when the paint baking time reaches the set time, the sandblasting room will automatically shut down and the baking will be finished. The surface treatment process of wind tower body relates to a surface treatment process of wind tower body, especially an anti-corrosion coating process of wind tower body. It mainly includes the following process: preparation before sand blasting, sand spraying, inspection sand spraying, hot zinc spraying, zinc spraying inspection, zinc spraying out of the sand spraying room, installation of rotary tooling into the sand blasting room, pre coating, coating of flange, door frame and cable support and support, inspection and coating, repair, inspection and repair, test, and end of surface treatment. No need to build a large number of tall scaffolding, reduce the cost, but also ensure the personal safety of staff. Batch curing barn, that is, the products are put into the curing barn in batches for heating and drying, with small investment. It is suitable for small enterprises, but not suitable for large-scale production enterprises. The area is determined according to the production scale of the enterprise, combined with the layout form of the plate, and the product size is comprehensively considered. When the area of curing barn is between 100m2 and 150m2, if it is connected with spraying room, the area will be increased and the relative investment will be reduced.

The main feature of the sandblasting room is that the operator is in the room during the sandblasting process. The protective clothing and helmet can prevent the operator from being impacted by abrasive, and the ventilation device provides fresh air for the operator through the helmet. Sandblasting room is mainly used for large parts or using automatic sand blasting device to process very expensive parts. The nozzle manipulator installed in the sandblasting room can carry out automatic sandblasting on the surface of parts, and the hard to reach area can be finished by manual sandblasting. This not only maintains the flexibility, but also reduces the number of sandblasting operators. Abrasive transport mode is another highlight of the equipment design. In addition to the well-known flat conveying ground with very small installation depth, Desa has rich experience in screw conveyor and vibrating cross grid abrasive conveying technology. For large workpieces, open sand blasting is generally used.
