Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a self-cleaning industrial air filter. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the low-dust air into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] For example, the authorization announcement number "CN216537591U" is named a self-cleaning industrial air filter. Although a high-pressure water flow discharged from a cleaning cross plate is provided to comprehensively clean the filter steel mesh, so that the filter steel mesh has a self-cleaning function, the filter steel mesh remains unobstructed, and can continuously and effectively filter and purify the air with high dust concentrations to avoid dust blockage, thereby effectively improving the air purification efficiency. However, the existing self-cleaning industrial air filter, because only the dust filter steel mesh is provided with a self-cleaning structure in the air filter, there is also an activated carbon filter plate on the rear side of the air filter to enhance the air purification effect. However, the activated carbon filter plate is indeed manually taken out and then replaced and cleaned, which is not only troublesome to operate but also more expensive to clean and maintain the activated carbon. Therefore, the use cost of the existing self-cleaning industrial air filter will increase.

[0004] At the same time, the existing self-cleaning industrial air filter adopts a structure that can slide up and down and scrape the accumulated dust to clean the filter steel plate. However, the cleaning brush is fixed inside the air filter. As the self-cleaning industrial air filter is started frequently, the bristles on the cleaning brush will gradually fall off, and thicker dirt and mud will also adhere to the cleaning horizontal plate that moves up and down, which not only makes cleaning more laborious, but also reduces the cleaning effect of the filter steel plate, thereby affecting the cleaning effect of the self-cleaning industrial air filter. Utility Model Content

[0005] The utility model aims to solve the problems of high use cost and poor use effect of the existing self-cleaning industrial air filter, and proposes a self-cleaning industrial air filter.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning industrial air filter, comprising an air inlet pipe, an air inlet port and an air outlet, wherein the lower end of the air inlet pipe is provided with an automatic cleaning structure for an activated carbon filter plate, wherein the automatic cleaning structure for the activated carbon filter plate comprises a shell, a motor and a soft brush, wherein the shell is fixedly mounted on the lower end of the air inlet pipe, an upper outer wall of the shell is fixedly connected with a water inlet pipe, a drain pipe is fixedly mounted on the lower end of the shell, the motor is fixedly mounted on the bottom end of the shell, an output shaft of the motor is rotatably connected with a rotating rod via a sealed bearing, and soft brushes are fixedly connected on both sides of the rotating rod.

The two through holes are fixedly opened on the outer wall of the lower end of the air inlet pipe, and the other side of the through hole is fixedly opened on the top of the outer shell, and the lower end of the activated carbon filter plate is slidably connected to the through hole.

[0010] Preferably, the lower ends of the two activated carbon filter plates are slidably connected to the outer shell, and the ends of the two soft brushes are movably connected to the activated carbon filter plates.

[0011] Preferably, a filter steel mesh flushing structure is provided above the air inlet pipe;

[0012] The filter steel mesh flushing structure comprises a water tank, a connecting rod and a filter steel mesh;

[0013] The filter steel mesh is fixedly installed inside the air inlet pipe, the water tank is fixedly installed on the top of the air inlet pipe, one side of the water tank is fixedly connected to a water pipe, a water pump is fixedly installed above the water pipe, the connecting rod is fixedly installed inside the air inlet pipe, one side of the connecting rod is fixedly connected to a plurality of high-pressure nozzles, and the tops of the plurality of high-pressure nozzles are connected to the water pipe.

[0014] Preferably, a sewage discharge structure is provided on the inner side of the air inlet pipe;

[0015] The sewage discharge structure includes a drainage slope, a collection pipe and a sewage pipe;

[0017] Preferably, an air inlet is fixedly provided at the top end of the air inlet pipe, and the air outlet is fixedly installed at the other end of the air inlet pipe.

[0018] The utility model proposes a self-cleaning industrial air filter, which has the beneficial effect of: the motor drives the rotating rod to rotate slowly through the sealed bearing, and then the soft brush will be driven to wash the dust and impurities on the activated carbon filter plate into the clean water, and finally after the cleaning is completed, the valve is manually turned to discharge the dirty water to the outside along the drain pipe. The activated carbon filter plate can be cleaned alternately at the same time, which reduces the labor input and workload, thereby reducing the use cost of the self-cleaning industrial air filter.

[0019] When the filter steel mesh is clogged with dust, the water pump will lead the clean water inside the water tank along the water pipe, and then transport it to the multiple high-pressure nozzles below. The high-pressure nozzles generate a water column with a certain pressure and spray it onto the filter steel mesh. The stable high-pressure water flow is used to achieve the cleaning work, which avoids the bristles of the cleaning brush falling off after long-term use and the dirt sticking to the cleaning plate, thereby improving the cleaning effect of the self-cleaning industrial air filter.
