Multi-layer type water curtain spraying chamber

Abstract

The present invention discloses a multi-layer type water screen spray room, whose inside is provided with a water screen plate, and the inside of the spray room is divided into the front spray painting operating area and the back painting mist processing area. The bottom of the whole spray room is provided with a water tank, and an air flow channel is formed between the water tank and the water screen plate. The upper part of the painting mist processing area is provided with an air exit, and the upper part of the spray painting operating area is provided with a uniform compression chamber. The uniform compression chamber is connected with the central wind supplying system to make the dissipated paint mist in the whole spray painting operating area can be fully absorbed to the painting mist processing area for processing, moreover, the invention can reduce the energy consumption of the whole system and is convenient for the maintenance of the system. The inside of the painting mist processing area is provided with a glue flower layer, and a plurality of water spray nozzles, and the glue flower layer further absorbs the residual paint mist to ensure the processing effect of paint mist. The water screen plate comprises the upper and lower layer water screen plates, and the upper and lower water screen plates are all provided with water tanks. The invention makes the spray room provide different spray painting environments according to the spray coating requirement of the working piece by choosing to start the water screen plate.

Description

technical field [0001] The invention relates to a spray processing equipment, in particular to a multi-layer water curtain spray booth. Background technique [0002] When using spraying equipment to spray the workpiece, there will always be some paint mist not attached to the surface of the workpiece but scattered around the workpiece, which is called spray paint mist. The existence of these sprayed paint mist in the spraying workshop will not only affect the health of the operators, but also may cause fire and explosion. If the paint mist is discharged directly to the environment, it will cause environmental pollution and affect the quality of life of nearby residents. For example, it can make people feel unwell, with symptoms such as headache, dizziness, nausea, vomiting, loss of appetite, and inability to concentrate. In addition, it also affects the respiratory system, circulatory system, digestive system and reproductive system. [0003] At present, the spraying devic...

Problems solved by technology

However, there are also some problems that need to be improved in this water curtain spray booth: since the sprayed paint mist is a certain distance away from the entrance of the paint mist treatment area, the amount of air required to suck all the air containing the sprayed paint mist is quite large. If it is large, it needs to consume more energy; the water baffle in the paint mist treatment area can only block the water from entering the water tank, but cannot further absorb the remaining paint mist, resulting in insufficient paint mist treatment effect in the paint mist treatment area, and some The paint mist escapes from the air exhaust port and adheres to the exhaust fan; in addition, the water curtain plate and the water curtain formed in the existing spray booth are single-layer, so it is impossible to choose and set different spraying environments according to the size of the workpiece, and Loose structure, high cost, high energy consumption, and inconvenient maintenance
