Water curtain paint spraying chamber and paint spraying method thereof

Abstract

The invention discloses a water curtain paint spraying chamber. The water curtain paint spraying chamber comprises an overflow tank, a box-shaped frame, a water tank, a water replenishing tank, a high-pressure spraying plate, a spraying water tank, a circulating pump, a circulating loop, a gas-liquid separation bin, a draught fan and a water curtain device. The water curtain paint spraying chamber is characterized in that the overflow tank is fixedly installed on the top of the water curtain paint spraying chamber, the spraying water tank is installed under the overflow tank, and the water curtain device is located on the right side of the spraying water tank; a sliding block is slidably installed on a sliding rail, a hoisting device is fixedly installed under the sliding block, the spraying water tank is installed on the left side of the water curtain device, and the upper end of the spraying water tank is connected with the bottom of the overflow tank. According to the water curtain paint spraying chamber, the water curtain area is increased, the paint mist filtering procedure is optimized, and therefore air is filtered more thoroughly; meanwhile, water in the water tank is reutilized after being filtered, therefore, the processing cost is reduced, and water supply sources are reduced.

Description

technical field [0001] The invention relates to a painting process, in particular to a water curtain spray booth and a painting method thereof. Background technique [0002] The working principle of the water curtain spray booth is to make the inner wall of the front of the room body into a smooth running water board, and pump water into the tank on the top of the running water board, and a waterfall-like water curtain will be formed on the board surface during operation. When spraying paint, the paint mist collides with the water curtain and is absorbed by the water and rushed to the lower water tank for accumulation, so that the chamber wall will not be polluted. The paint mist that has not touched the water curtain is further collected and absorbed by the water mist sprayed from the atomizing nozzle in the ventilation system, so as to achieve the complete treatment of the paint mist. [0003] Now there is a water curtain spray booth that only uses one filtration process,...

AI Technical Summary

Problems solved by technology

[0003] At present, there is a water curtain spray booth that only uses one filtration process, which makes the paint mist filter incomplete. The water source of the water curtain adopts active water source, which increases the cost, and it is very difficult to salvage the paint scum.
