Description

Technical Field

[0001] The invention relates to paint spraying equipment, in particular to a paint spraying and polishing water curtain cabinet. Background Art

[0002] The desktop paint spray box is a small paint spraying machine. It is widely used because of its compactness and practicality. The paint spraying exhaust gas purification and emission device with application number 201820977309.X and the automatic paint spraying machine with application number 201810061586.0 both use a fan to suck the exhaust gas from the paint spraying into the water curtain cabinet, and discharge it outside the water curtain cabinet after purification in the water curtain cabinet. However, there are two disadvantages in the existing technology. First, the water curtain plate is generally fixedly connected to the cabinet body of the paint spraying box. The water curtain plate cannot be cleaned after long-term use. At the same time, the filter part of the filter assembly behind the water curtain plate is difficult to replace; second, the product needs to be manually polished before painting, which is very inconvenient due to lack of space. At the same time, polishing and painting are carried out in different equipment, which is inconvenient to operate and wastes resources. If polishing is done directly in the paint spraying cabinet, the abrasive after polishing is likely to cause floating dust and pollute the air. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a spray painting and polishing water curtain cabinet which is flexible in assembly and disassembly and convenient for polishing and dust removal in view of the above problems.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: a water curtain cabinet for spray painting and polishing, comprising a cabinet body, a vertical partition provided in the cabinet body, a fan installed on the rear side of the partition, an operation port provided on the front side of the partition, the partition dividing the cabinet body to form a front cavity and a rear cavity, the bottoms of the front cavity and the rear cavity being connected to each other to form a water filter cavity;

[0005] A water curtain plate is provided on the front side of the partition, which is arranged parallel to the partition and movably connected to the cabinet body; a first filter assembly is provided on the side of the water curtain plate close to the partition;

[0006] A grinding and dust removal component is movably installed in the front chamber. The front chamber can be used as a paint spraying chamber or a grinding exhaust chamber. An expansion component for increasing the operating platform of the front chamber is provided at the operation port of the front chamber.

[0007] A second filter assembly is provided in the water filter cavity and can be moved and extended forward and backward along the cabinet body.

[0008] The water curtain plate is magnetically connected to the cabinet body. The water curtain plate can be cleaned by manually pulling open the magnetic connection between the water curtain plate and the cabinet body. At the same time, after using the first filter component to filter impurities in the oil and gas for a certain period of time, the filter element part of the first filter component needs to be replaced. As long as the water curtain plate is taken out or turned over, the filter element part of the first filter component can be easily replaced.

[0009] An upper water diversion trough is provided on the top of the water curtain plate, which is magnetically connected to the cabinet. A magnet is provided on the top of the upper water diversion trough and the upper water diversion trough is magnetically connected to the cabinet through the magnet. The upper water diversion trough is "L"-shaped, and the side of the upper water diversion trough close to the water curtain plate is open and has a gap with the water curtain plate.

The top of the receiving cabinet is open and the dust collection plate is covered on the top of the receiving cabinet. A plurality of ash leakage holes are provided on the dust collection plate. The joint is fixed on the side of the receiving cabinet and can be connected to the fan pipe fitting. The suction force of the fan is used to generate negative pressure in the receiving cabinet, and the abrasive for polishing the blank falls into the blank through the ash leakage holes, which greatly reduces the abrasive floating in the air and is then sucked out through the fan and the pipe. It is not only environmentally friendly, but also uses the same drive component (fan) to save costs.

[0012] In order to facilitate the expansion of space, the expansion component includes a frame body arranged along the front and rear directions of the cabinet and connected to the front cavity, and a push plate arranged at the bottom of the frame body.

The lower water tank is arranged in the water filter cavity and can be extended and retracted along the cabinet body. The filter table is arranged in the lower water tank. The lower filter screen is fixed on the top of the filter table. Several support legs are provided and fixed on the bottom of the filter table. A water pump is provided in the lower water tank. The water pump is connected to the upper water tank pipeline. The upper water tank, the lower water tank and the lower water tank form a circulation loop through the water pump.

[0014] The first filter assembly includes a first filter frame and an upper filter arranged on the first filter frame. The first filter frame is provided with two filters arranged in parallel with a receiving cavity between the two. The upper filter is arranged in the receiving cavity and is used to filter the oil-gas mixture during paint spraying. The upper filter can be filter cotton to prevent paint mist from contaminating the fan and extend the service life of the fan.

[0015] A check valve is installed on the top of the rear cavity, and the fan is connected to the check valve pipeline to prevent the exhaust gas from flowing back and improve the waste cleaning effect.

[0016] In order to facilitate closing and opening of the cabinet, a cover plate is magnetically attached to the side of the cabinet close to the operating port.

[0017] The beneficial effects of the present invention are as follows: by adopting the above-mentioned scheme, the present invention can firstly directly remove the water curtain plate after removing the upper water trough, thereby facilitating the cleaning of the water curtain plate or the replacement of the upper filter screen; secondly, it is convenient to expand the painting and polishing space, and when the polishing filter assembly is connected to the fan, it can better remove dust and absorb floating dust, which is environmentally friendly and cost-saving.
