Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying waste gas treatment, in particular to a cyclone paint spraying cabinet. Background Art

[0002] Spray painting is a coating process in which paint is sprayed onto the surface of an object in an atomized form through a spray gun to achieve decorative, protective and functional purposes. Spray painting is widely used in the fields of automobiles, furniture, construction, electronic equipment, etc. In the industrial production process, the dust and exhaust gas generated in the spray painting production workshop usually need to be adsorbed using a cyclone spray cabinet to protect the environment and the health of operators.

[0003] Existing cyclone spray booths usually use a cyclone cylinder and a water curtain plate to reduce dust and exhaust gas, but this method has a low degree of exhaust gas treatment, and there is still exhaust gas leakage that harms the environment and the health of operators. In addition, the water curtain plate needs to be supplied with water using a circulating water tank and a circulating water pump. Due to the large amount of impurities adsorbed in the water, the circulating water pump may be blocked, causing unnecessary economic losses. Therefore, a cyclone spray booth is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cyclonic paint spraying cabinet to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cyclone paint spraying cabinet comprises an outer shell, a water storage tank with a top opening at the top of the outer shell is provided at the top end, a water curtain plate which penetrates the water storage tank and the outer shell and is arranged obliquely is fixedly connected to the bottom end of the water storage tank, a vertically arranged cyclone cylinder is provided on the inner side of the outer shell, a partition plate which is fixedly connected to the top inner side of the outer shell on one side of the cyclone cylinder, a horizontally arranged locking column is fixedly connected to one side of the partition plate, a drawer which penetrates the outer shell and is engaged with the locking column is provided on one side of the outer shell, an activated carbon plate is fixedly connected to the inner side of the drawer located below, and a PVC defogger plate is fixedly connected to the inner side of the drawer located above, a negative pressure fan which is fixedly connected to the top end of the outer shell and penetrates the outer shell is provided on the rear side of the water storage tank, an air collecting box which has a bottom opening and is fixedly connected to the top end of the outer shell is provided above the negative pressure fan, and an exhaust pipe which penetrates the inner side of the air collecting box is fixedly connected to the top end of the air collecting box.

[0007] Preferably, one side of the water tank is fixedly connected to a circulating water pipe that passes through the water tank, an end of the circulating water pipe away from the water tank is fixedly connected to a circulating water pump that passes through the circulating water pipe, an end of the circulating water pump away from the circulating water pipe is fixedly connected to a snap-fit ​​cover that passes through the circulating water pump, and a filter cartridge is snap-fitted to the inner side of the snap-fit ​​cover.

[0008] Preferably, the number of the circulating water pipe, circulating water pump, snap-fit ​​cover and filter cartridge are two each, the snap-fit ​​cover and filter cartridge are located inside the shell, and one end of the circulating water pump close to the snap-fit ​​cover is fixedly connected to the shell and passes through the shell.

[0009] Preferably, the number of the cyclone cylinders is two, the number of the engaging columns is six, and the activated carbon plate and the PVC demisting plate are the same in shape and size.

[0010] Preferably, the activated carbon plate and the PVC defogger plate are both connected to the snap-fitting columns, the number of the drawers is two, and the number of the negative pressure fans is three.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the cyclone cylinder, partition plate, snap-fit ​​column, drawer, activated carbon plate, PVC defogger plate, negative pressure fan, wind collecting box and exhaust cylinder are arranged to further process the waste gas, improve the adsorption and filtration degree of the waste gas, and reduce the escape of the waste gas. Before use, the equipment is powered on, and the drawer is first inserted into the inner side of the shell, so that the drawer, the activated carbon plate and the PVC defogger plate are snap-fitted and connected with the snap-fit ​​column on one side of the partition plate, and then the negative pressure fan and the cyclone cylinder are started. At this time, the dust or waste gas generated in the production workshop is sucked under the traction of the negative pressure fan. Attached to the inner side of the shell, a part of the emulsified waste gas particles generated by spraying paint or glue falls into the water at the bottom of the inner side of the shell with the water curtain plate. At this time, the paint mist, cyclone and water enter the inner side of the cyclone cylinder and rotate at high speed to carry out gas-liquid emulsification reaction. The high-speed operation of the cyclone cylinder makes the paint mist and the rotating liquid fully mixed, and the paint liquid is separated under the action of centrifugal force. The dust particles separated from the paint mist sink to the bottom of the water tank. The impurities in the separated gas are adsorbed by the activated carbon plate and the PVC demisting plate. Finally, the gas enters the exhaust gas treatment equipment at the rear end through the negative pressure fan, the air collecting box and the exhaust pipe;

[0013] 2. In the utility model, the circulating water pipe, circulating water pump, snap-fit ​​cover and filter cartridge are provided to prevent impurities in the water from clogging the circulating water pipe or the circulating water pump. Before use, the filter cartridge is inserted into the inner side of the snap-fit ​​cover so that the filter cartridge and the snap-fit ​​cover are snap-fitted and connected. At this time, the circulating water pump is started and the impurities in the water can be isolated from the outside by the filter cartridge. BRIEF DESCRIPTION OF THE DRAWINGS
