Description

Technical Field

[0001] This utility model relates to the field of spray filter tower technology, specifically a spray filter tower for use in a powder spraying workshop. Background Technology

[0002] The powder coating process generates various pollutants that seriously impact the environment and human health. During powder coating, some powder inevitably escapes into the air during application and recycling. These tiny dust particles remain suspended in the workshop for extended periods. On one hand, they affect visibility, interfere with operators' vision, reduce work efficiency, and increase the risk of operational errors. On the other hand, long-term inhalation of these dust particles can lead to health problems such as pneumoconiosis and respiratory diseases.

[0003] When using a spray filter tower, it is necessary to spray the gas containing dust to remove the dust, and then remove the harmful substances in the gas through the filtration mechanism. However, when the existing spray tower sprays the gas containing dust, the air flow rate in the middle of the spray tower is large, and the nozzles inside the spray tower are evenly distributed, which easily leads to incomplete treatment. Utility Model Content

[0004] The purpose of this utility model is to provide a spray filter tower for powder spraying workshops, which has the advantages of optimized nozzle layout, resulting in uniform spraying treatment. It solves the problem that the uniform distribution of nozzles inside the spray tower, coupled with the large air flow in the middle of the spray tower, easily leads to incomplete treatment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray filter tower for a powder coating workshop, comprising a spray device, the spray device comprising a spray tower, a water tank provided on one side of the outer edge of the spray tower, a spray mechanism extending into the spray tower installed at the top of the water tank, a water pump provided on one side of the water tank, and a water level gauge provided on the other side, the output end of the water pump being connected to the spray mechanism, the spray mechanism comprising a water pipe, the water pipe being provided with several horizontal pipes, each of the horizontal pipes extending into the spray tower, a first air pipe provided at the top of the spray tower, a filter mechanism installed at the end of the first air pipe away from the spray tower, and a second air pipe installed on the side of the filter mechanism away from the first air pipe.

[0006] Preferably, one end of the horizontal pipe passes through the side of the spray tower and extends into the spray tower, and a bracket is installed at the top of the horizontal pipe, and a filter plate is installed at the top of the bracket.

[0007] Preferably, the horizontal tube is arranged in a spiral shape at the bottom of the support, and a number of nozzles are provided at the bottom of the horizontal tube, and a number of through grooves with a diamond-shaped cross-section are opened in the filter plate.

[0008] Preferably, the filtration mechanism includes a filter box, which is a hollow box-shaped structure with an opening on one side and two symmetrical doors at the opening. Both sides of the filter box are provided with slots that communicate with the first air pipe and the second air pipe, respectively.

[0009] Preferably, the filter box is provided with several partitions, which divide the interior of the filter box into a filter channel with a vertical cross-section of S-shape. Several activated carbon plates that divide the filter channel are horizontally inserted into the filter channel.

[0010] Preferably, the second air pipe has an L-shaped vertical cross-section, and a fan for extracting gas from the filter mechanism is provided in the middle of the second air pipe.

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

[0012] 1. This utility model uses a water pipe, a horizontal pipe, and nozzles to deliver water, which is then sprayed out from the nozzles at the bottom of the spiral horizontal pipe. The nozzles in the middle of the spiral horizontal pipe are relatively dense, which can effectively target the large air flow in the middle of the spray tower, ensuring that each area can be fully sprayed, avoiding dead corners and improving the spraying effect.

[0013] 2. This utility model, by setting up a filter box, partitions, filter channels and activated carbon plates, uses several partitions to divide the inside of the filter box to form a filter channel, which can increase the gas travel within the filter box. The gas is filtered and adsorbed by several activated carbon plates, thus improving the gas treatment effect. Attached Figure Description

A first air pipe 3 is provided at the top of the spray tower 11. A filter mechanism 4 is installed at the end of the first air pipe 3 away from the spray tower 11. A second air pipe 5 is installed on the side of the filter mechanism 4 away from the first air pipe 3. One end of the horizontal pipe 22 passes through the side of the spray tower 11 and extends into the spray tower 11. A support is installed at the top of the horizontal pipe 22. The frame 23 has a filter plate 24 installed at its top. A horizontal tube 22 is arranged in a spiral shape at the bottom of the frame 23, and several nozzles 25 are provided at the bottom of the horizontal tube 22. Several through slots with a diamond-shaped cross-section are opened inside the filter plate 24. The filtration mechanism 4 includes a filter box 41, which is a hollow box-shaped structure. An opening is provided on one side of the box-shaped structure, and two doors 42 are symmetrically arranged at the opening. Both sides of the filter box 41 have slots that communicate with the first air pipe 3 and the second air pipe 5, respectively.

[0024] Working principle: In operation, the water pump 13 draws liquid from the water tank 12 and delivers it to the water pipe 21. The water level gauge 14 observes the liquid content in the water tank 12. Water is delivered through the water pipe 21 and then sprayed out from the nozzle 25 at the bottom of the spiral horizontal pipe 22. The nozzles 25 in the middle of the spiral horizontal pipe 22 are relatively dense, which can effectively target the large air flow in the middle of the spray tower 11. After spraying, the gas enters the filter mechanism 4 through the first air pipe 3. Several baffles 43 divide the interior of the filter box 41 to form a filter channel 44, which can increase the gas travel in the filter box 41. Several activated carbon plates 45 filter and adsorb the gas. The gas is then drawn out by the fan 6 and discharged through the second air pipe 5.
