Description

Automatic water cyclone painting system

technical field

The utility model relates to a surface coating equipment, in particular to a water cyclone paint spray booth, which belongs to the field of industrial coating.

Background technique

At present, the existing water spin paint diffusion device mainly includes an air supply system, a grid assembly, a paint mist filter, and the like. This type of water cyclone device, its air supply system brings a lot of material impurities when it enters the spray booth, which affects the quality of workpiece spraying to a large extent. During the painting process, a large amount of paint mist and organic solvent gas will be produced. The concentration of paint mist and organic solvent discharged from the spray booth is 300~200mg/HM, which affects the health of the operator and seriously pollutes the surrounding air and environment.

Utility model content

The purpose of the utility model is to solve the deficiencies of the prior art and provide a clean and environment-friendly automatic water cyclone paint spraying system.

The automatic water cyclone paint spraying system of the present utility model comprises an air supply system, a water cyclone paint spraying room, a paint mist filtering device, a purification system, a circulation system and an exhaust system connected in sequence,

Preferably,

In the automatic water cyclone painting system of the present utility model, said air supply system is provided with filters at the entrance and exit, is provided with a heat exchanger, a resistive muffler inside, and is provided with an elastic shock absorber at the bottom. The filter at the inlet is used for primary air filtration control, and the filter at the outlet is used to purify the air from F5 to F8, which can be said to be purified from 45% to 95%, so as to make the spray booth clean and improve the painting quality of the painted workpiece. The heat exchanger is used for air heating to control the heating of the spray booth. The resistive muffler is used to eliminate the noise generated by the fan and the flow of air flow into the spray booth through the air supply pipe. The elastic shock absorber is used to greatly reduce the vibration of the fan in operation, thereby prolonging the service life of the fan;

In the automatic hydrocyclone painting system of the present invention, said hydrocyclone spray booth includes a pressure equalizing chamber arranged at the top, an equalizing layer arranged at the middle, a filter and a hydrocyclone arranged at the bottom.

In the automatic water cyclone paint spraying system of the present utility model, said paint mist filtering device includes a water level meter control system and a water cyclone device. The water level meter control system is used to automatically stop water supply when the water level is too high, and automatically provide water supply when the water level is too low. The water cyclone device is used to press the splashed waste paint mist into the hydrocyclone of the hydrocyclone spray booth. The water is atomized under the impact of high-speed airflow and fully mixed with the waste paint mist, so that the paint mist is attracted into the water and taken away.

In the automatic water cyclone painting system of the present utility model, said circulation system includes a circulation pool and a circulation pump.

In the automatic water cyclone paint spraying system of the present utility model, said exhaust system includes an exhaust pipe and a hood.

The utility model has the following technical effects in the automatic water cyclone paint spraying system:

1. Simple structure and high degree of automation;

2. Uniform spraying and high spraying quality;

3. Energy saving and environmental protection, the purification rate of paint mist after purification is ≥98%; the exhaust gas discharged into the atmosphere can reach the national standard.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the automatic water cyclone painting system of the present invention includes an air supply system 1, a water cyclone painting room 2, a paint mist filter device 3, a purification system 4, a circulation system and an exhaust system connected in sequence 5. The air supply system 1 is provided with filters 1-1 and 1-2 at the inlet and outlet, a heat exchanger 1-3, a resistive muffler 1-4 inside, and an elastic shock absorber 1 at the bottom -5. The hydrocyclone spray booth 2 comprises a pressure equalizing chamber 2-1 at the top, an equalizing layer 2-2 at the middle, filters 2-3, 2-4 and a hydrocyclone 2-5 at the bottom.
