In the roasting workshop, all alkaline liquid tanks in the workshop are prone to form gibbsite crystals, resulting in a large amount of crystals accumulating in the tanks, pumps, and pipelines, which are very difficult to clean. Especially in the pumps and pipelines, the cleaning difficulty is extremely high, and a filter is required to filter the crystals.

[0003] After retrieval, in the prior art (publication number: CN209173474U), a filter plate of a filter is proposed, which states that "it includes a plate body, and a number of filter holes are provided on the plate body. A round tube is integrally provided on the plate body, and a reinforcing rib for dividing the filter holes into several pieces is integrally provided on the round tube. A first rounded corner is further provided on the side of the reinforcing rib away from the round tube, and a second rounded corner is further provided on the filter hole". However, when the prior art is in use, it cannot clean the impurities filtered out by the filter plate, resulting in the crystals easily blocking the filter holes of the filter plate when filtering alkaline liquids, which will affect the discharge of alkaline liquids. Therefore, it is very necessary to design an anti-blocking filter. Content of the Utility Model

[0010] Preferably, guide plates are welded to the inner walls on both sides of the discharge pipe, and a pressure roller is arranged below the bottom of the guide plate. One end of the pressure roller is fixed with a second micro motor, and a discharge port is formed below the bottom of the discharge pipe.

[0011] Preferably, the guide plate is triangular. The two second micro motors respectively drive the two pressure rollers to rotate in opposite directions. The pressure roller is cylindrical and has a smooth surface.

[0012] Preferably, a controller is screwed to the outer wall of one side of the filter cylinder.

[0013] Preferably, a feed pipe is welded to one end of the filter cylinder, a discharge pipe is welded to the other end of the filter cylinder, and flange plates are welded to the other ends of the feed pipe and the discharge pipe.

[0014] Preferably, a valve rod is arranged on the feed pipe, a valve plate is welded to the valve rod, and a hand wheel is welded to one end of the top of the valve rod.

[0017] Through the screen, gibbsite crystals in the alkaline liquid can be filtered out. The scraper is driven by the reduction motor to rotate, and the gibbsite crystals filtered out on the screen can be pushed to the discharge port, realizing the cleaning effect. At the same time, the arc-shaped scraper structure and the round groove can better guide the crystals to move to the discharge port. Through the X-shaped support, the support and fixation effect on the reduction motor can be improved, which is beneficial to improving the stability of the filter cylinder.

[0018] By driving the sealing plate to turn downwards by the first micro motor, the gibbsite crystals can enter the discharge pipe. Through the guide plate, the crystals discharged from the discharge port can be guided between the two pressure rollers. By driving the pressure rollers to rotate by the second micro motor, the crystals can be rolled to reduce the volume, and the crushed crystals will be discharged through the discharge port. By turning the hand wheel, the orientation of the valve plate can be adjusted, and the valve plate can be used to block the feed pipe to prevent the alkaline liquid from flowing into the filter cylinder and affecting the cleaning work. The sealing gasket can be used to improve the sealing performance of the valve plate. Description of the drawings
