[0002] Aluminum powder is an important metal powder material, which is widely used in chemical industry, coating, refractory material, aluminum alloy and other fields. During the production of aluminum powder, a small amount of aluminum powder will enter the dust removal system with nitrogen. In order to reduce the burden of the dust removal system, a filter device is generally used to filter the aluminum powder and nitrogen before they enter the dust removal system.

[0003] At present, the filter device usually uses a filter screen plate for filtering. The filter screen plate needs to be replaced after being used for a period of time. However, when replacing the filter screen plate, the existing filter device often needs to be paused, which will affect the production progress. Therefore, there are still defects and deficiencies in the prior art. SUMMARY

[0005] In order to solve the above technical problems, the utility model adopts the technical scheme of a horizontal filter device for aluminum powder production, which comprises a filter tank arranged horizontally. One end of the filter tank is provided with an air inlet pipe, and the other end of the filter tank is provided with an air outlet pipe. Two first partition plates are fixedly connected in the filter tank and arranged vertically and spaced apart. A second partition plate is fixedly connected between the two first partition plates. The second partition plate divides the space between the two first partition plates into two filter chambers. A filter screen plate is arranged vertically and detachably in the filter chamber. A filter through hole is arranged on the first partition plate and communicates with the filter chamber. A rotating shaft is arranged vertically on the outer side of the first partition plate. The rotating shaft is located between the two filter chambers. The two ends of the rotating shaft are rotatably connected to the filter tank. A sealing plate is fixedly connected to the rotating shaft. The rotating shaft can drive the sealing plate to block the filter through hole. The bottom ends of the two rotating shafts extend out of the filter tank and are coaxially fixed with gears. The two gears are meshed.

[0006] Preferably, two vertical grooves are formed in the inner side wall of the filter chamber and located at the two ends of the filter screen plate. The two ends of the filter screen plate are located in the grooves and are slidably connected with the grooves. A pull-out opening is formed in the filter tank and matched with the filter screen plate. The top end of the filter screen plate is fixedly connected with a cover plate which is matched with the pull-out opening and located outside the filter tank. The cover plate is detachably connected with the filter tank by bolts.

[0007] Preferably, a handle is fixedly connected to the outer side of the cover plate.

[0008] Preferably, the top end of one of the rotating shafts extends to the outside of the filter tank and is fixedly connected to a handle. A fixed cylinder sleeved on the rotating shaft is fixedly connected to the top surface of the filter tank. The fixed cylinder is rotatably connected to the rotating shaft. A horizontally arranged screw is threaded onto the fixed cylinder. One end of the screw extends into the fixed cylinder, and the other end of the screw is coaxially fixed to a handwheel located outside the fixed cylinder.

[0009] Preferably, both sides of the sealing plate are fixedly connected with sealing rubber rings that are compatible with the filter holes.

[0010] Preferably, an inverted conical collection trough is provided on the bottom surface of the filter chamber. The collection trough is located on the side of the filter plate near the air inlet pipe. The bottom surface of the collection trough is connected to a vertically arranged discharge pipe, and a valve is installed on the discharge pipe.

[0011] The beneficial effects of this utility model are as follows: (1) This utility model divides two filter chambers in the filter tank and seals one of the filter chambers by setting a sealing plate, so that the filter plate can be replaced without stopping the use of the device, and thus the normal production progress can be maintained; (2) Since the filter plate is slidably connected to the filter chamber, the filter plate can be pulled out from the filter chamber after the cover is removed, so that the filter plate can be easily replaced.
