The lower part of the silicon powder collection tank is connected to an N2 feed line. A silicon powder discharge line is also provided between the silicon powder collection tank and the collection bucket. A discharge valve is provided on the silicon powder discharge line. An exhaust gas discharge pipe is also connected between the collection bucket and the exhaust gas filter. An exhaust gas vent is also provided on the exhaust gas filter. The silicon powder discharge line is connected to the collection bucket through a quick connector." This system can solve the problem of silicon powder collection devices being difficult to fix. However, the silicon powder collection tank does not have a filtration function, which greatly reduces the practical effect of the tank and affects the usability of silicon powder recycling.

[0004] Therefore, a novel silicon powder collection system is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a silicon powder collection system to solve the problem mentioned in the background art that the silicon powder collection tank does not have a filtration function, which greatly reduces the practical effect of the tank and affects the usability of silicon powder recycling.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silicon powder collection system, including a silicon powder collection tank, wherein a feed pipe is vertically installed through the center of the top of the silicon powder collection tank, and a high-efficiency fixed filter assembly is installed at the top inside the silicon powder collection tank.

[0007] The filter assembly includes a filter plate, and external plates are fixedly connected to both sides inside the silicon powder receiving tank. An installation groove is opened on the surface of the external plate. A screen is fixedly connected to the bottom end of the filter plate, and limit baffles are fixedly connected to both sides of the screen.

[0008] As a further technical solution of this utility model, the bottom of the limiting baffle is sleeved on the outside of the outer plate, and the bottom of the limiting baffle is inserted into the mounting inner groove, and the top of the limiting baffle extends.

[0009] As a further technical solution of this utility model, four sets of supporting base frames are equally spaced around the outer end of the bottom of the silicon powder receiving tank. A connecting sleeve is provided through the inside of the supporting base frame. A fixing frame is fixedly connected to the inner wall of the connecting sleeve. The inner wall of the fixing frame is in contact with the outer end of the silicon powder receiving tank.

[0010] As a further technical solution of this utility model, the inner wall of the feed pipe is provided with an internal threaded sleeve, and a sealing layer is fixedly connected to the inner wall of the feed pipe.

[0011] As a further technical solution of this utility model, the internal threaded sleeve is fixedly connected to the inner wall of the sealing layer.

[0012] As a further technical solution of this utility model, connecting frames are fixedly connected to both sides of the top of the outer end of the silicon powder receiving tank, and a reinforcing plate is attached to the top of the feeding pipe.

[0013] As a further technical solution of this utility model, the interior of the reinforcing plate is provided with a through groove, the outer end of the top of the connecting frame is provided with a vertical groove, and the inner walls of the four corners of the reinforcing plate are fixedly connected with sliding plates.

[0014] As a further technical solution of this utility model, a movable block is fixedly connected to the inner end of the slide plate, and the movable block is slidably connected inside the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the silicon powder collection system not only realizes the filtering and cleaning function and the limiting and fixing function, but also realizes the supporting and protecting function;

[0016] The system includes a filter plate, a screen, limiting baffles, an outer plate, and an inner mounting groove. The filter plate is horizontally positioned inside the silicon powder receiving tank. Two sets of limiting baffles are fitted onto the surface of the outer plate and fixed in the inner mounting groove using a plug-in connection. This provides comprehensive fixation of the filter plate, enhancing its stability. The filter plate and screen work together to perform deep impurity removal on the silicon powder, ensuring its quality and improving the practicality of the silicon powder receiving tank. Simultaneously, it prevents the filter plate from tilting or shaking, enhancing the stability of both the filter plate and the screen.

[0017] By setting up a support base, connecting rings and fixing frames, multiple sets of support bases are equally spaced at the outer end of the silicon powder receiving tank. The connecting rings are used to penetrate the interior of the support bases laterally, which enhances the firmness and connection between the multiple sets of support bases. The fixing frames provide strong support and protection for the outer end of the silicon powder receiving tank.

[0018] The silicon powder receiving tank is equipped with a connecting frame, groove, reinforcing plate, sliding plate and moving block. The top of the silicon powder receiving tank is supported by a reinforcing plate. The reinforcing plate provides stable support and protection for the silicon powder discharge equipment, ensuring stability and safety during the receiving process. At the same time, the moving block is slidably installed in the groove, which pushes the reinforcing plate downward stably and fits it against the top of the feed pipe, avoiding the use of the reinforcing plate in the air, which would affect the stability.
