Description

Multi-layer water curtain spray booth

technical field

The utility model relates to a spray processing equipment, in particular to a multi-layer water curtain spray booth.

Background technique

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.

At present, the spraying device used to capture the sprayed paint mist is also called the spray booth, which is basically a rectangular parallelepiped chamber. According to the different ways of collecting the paint mist, it can be divided into the following types: oil washing type, spraying type , No pump type, dry type, water curtain type and so on. All kinds of spray booths have painting operation section and paint mist treatment section. At least one exhaust fan is installed on the top of the paint mist treatment section. Workpieces can be transported to the operation section by hanging chains, ground conveyors, trolleys or manual handling. Different types of spray booths have different structures in the paint mist treatment section. The purpose is to effectively capture paint mist, and at the same time, effectively separate paint particles, water droplets and air before discharging to the external environment. For example, water The curtain spray room is divided into the spraying operation section in the front and the paint mist treatment area in the rear by the water curtain plate in the room. There is a water tank in the lower part of the room, and an upper The dripping board, as well as several water baffles installed on the inner wall of the shell and the back of the water curtain plate, have an exhaust port on the shell above the paint mist treatment area. Under the action of the exhaust fan, the paint mist treatment area A strong negative pressure is formed, so that a strong air flow channel is formed between the lower mouth of the water curtain and the water surface of the water tank, and the paint mist around the workpiece in the spraying operation area, the water flowing down the water curtain and the water on the surface of the water tank flow down the slope The water board is sucked into the paint mist treatment area together, and enters the water tank after multiple sedimentation and mixing, so as to achieve the purpose of settling the paint mist and have a better use effect. However, there are also some problems that need to be improved in this water curtain spray booth: since the spray paint mist is at a certain distance from the entrance of the paint mist treatment area, the amount of air required to inhale all the air containing the spray 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 exhaust outlet 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 The structure is loose, the cost is high, the energy consumption is high, and the maintenance is not convenient enough.

Therefore, there is a need for an improved multi-layer water curtain spray booth to further improve the paint mist treatment effect, reduce cost and energy consumption, and reduce manpower and time waste caused by cleaning and maintenance.
