DETAILED DESCRIPTION

[0025] This part will describe the specific embodiments of the utility model in detail, and the preferred embodiments of the utility model are shown in the drawings, and the drawings are used to supplement the description of the text part to make people understand each technical feature and the overall technical scheme of the utility model intuitively and visually, but it cannot be understood as the limitation of the protection scope of the utility model.

[0026] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a raw material screening device for aluminum ingot production, including box 1, box 1 is rotatably installed with box door 2 in its inside. The inside bottom end of box 1 is fixedly installed with liquid storage tank 10 and collecting tank 12 respectively, and partition 11 is fixedly connected between liquid storage tank 10 and collecting tank 12. The bottom end of the side wall of box 1 is fixedly connected with blowdown pipe 3, and the inside of blowdown pipe 3 is communicated with liquid storage tank 10.

[0027] The upper portion of liquid storage tank 10 is provided with receiving tank 9, which is fixedly installed between partition 11 and the inner wall of box 1, and the bottom end of receiving tank 9 is provided with a drain hole.

[0028] The upper portion of receiving tank 9 is provided with screening plate 13, and the inner wall of box 1 is fixedly installed with motor 21 on both sides, and the output shaft of motor 21 is fixedly connected with electric push rod 22, and the telescopic ends of the two electric push rods 22 are oppositely arranged. The telescopic ends of the two electric push rods 22 are fixedly connected with the two sides of screening plate 13 respectively.

[0029] The upper end face of screening plate 13 is fixedly installed with inclined plate on the side close to electric push rod 22. By setting inclined plate, the raw materials will not slide out from both sides of inclined plate during screening, and at the same time, the inclined surface is beneficial to the raw materials on screening plate 13 falling into collecting tank 12 when scraper 17 pushes the raw materials on screening plate 13 into collecting tank 12.

[0030] The side wall of the box body 1 is fixedly provided with a support plate 4, and the support plate 4 is fixedly provided with a water tank 5. The inner top end of the box body 1 is fixedly provided with a water spraying assembly 8, which is a commonly used spraying pipe. The water spraying assembly 8 corresponds to the screening plate 13. The water tank 5 is fixedly provided with a water pump 6, and the output end of the water pump 6 is communicated with the water spraying assembly 8.

[0031] The top end of the box body 1 is fixedly provided with an inlet hopper 7 corresponding to the position of the screening plate 13.

[0032] The upper end surface of the screening plate 13 is slidingly provided with a scraper 17. Specifically, the upper end surface of the screening plate 13 is fixedly provided with a baffle 16 on both sides, and the baffle 16 is provided with a sliding groove 15. The sliding groove 15 is fixedly provided with a spring 14 inside, and the other end of the spring 14 is fixedly provided with a counterweight 20. The counterweight 20 is slidingly arranged in the sliding groove 15, and a plurality of rolling balls 23 are rollingly arranged on the side wall of the counterweight 20. The rolling balls 23 are rollingly matched with the inner wall of the sliding groove 15. Because the counterweight 20 is provided with the rolling balls 23, the friction between the counterweight 20 and the sliding groove 15 is much smaller than the gravity of the counterweight 20. The counterweight 20 is fixedly provided with a connecting rod 19, and the top end of the two connecting rods 19 is fixedly provided with a fixed plate 18. The scraper 17 is fixedly arranged on the bottom side of the fixed plate 18.

[0033] Working principle:

[0034] The raw materials to be screened are poured from the inlet hopper 7 onto the screening plate 13. At this time, the electric push rod 22 on both sides of the screening plate 13 is started, the output end of the electric push rod 22 is alternately stretched and retracted, thereby driving the screening plate 13 to reciprocate in the horizontal direction. At the same time, the water pump 6 is started, the water pump 6 supplies water to the water spraying assembly 8, the water spraying assembly 8 sprays water on the screening plate 13, and the raw materials on the screening plate 13 are cleaned, which can also prevent dust from being generated. The horizontal shaking of the screening plate 13 in the front-rear direction can effectively spread the raw materials on the screening plate 13 on the screening plate 13, and can also avoid the accumulation of raw materials to one side during screening. During the horizontal shaking of the screening plate 13, the raw materials on the screening plate 13 can repeatedly slide relative to the upper surface of the screening plate 13. Not only can the raw materials on the screening plate 13 be repeatedly turned over, but also the water can be uniformly sprayed on each surface of the raw materials, and each surface of the raw materials can be rubbed with the upper surface of the screening plate 13, thereby improving the cleaning effect of the raw materials.

[0035] Through the screening plate 13, the impurities passing through the screening plate 13 fall into the receiving tank 9, and the water flows from the drainage holes in the bottom wall of the receiving tank 9 into the liquid storage tank 10. The sewage in the liquid storage tank 10 can be discharged through the sewage discharge pipe 3.

[0036] The raw material that cannot pass through the sieve plate 13 remains on the sieve plate 13, at this time, the motor 21 is started, the output end of the motor 21 drives the electric push rod 22 to rotate, and then drives the sieve plate 13 to rotate to 90 degrees in the direction of the collecting box 12, wherein the sieve plate 13 is in the process of rotating, the gravity of the counterweight block 20 exerts pressure on the spring 14 to compress the spring 14, at this time, the counterweight block 20 slides in the chute 15 to the direction close to the collecting box 12, the sliding of the counterweight block 20 can drive the scraper 17 to slide on the sieve plate 13, and then the other kind of raw material on the sieve plate 13 is scraped into the collecting box.

[0037] When the sieve plate 13 is reset, because the rolling ball 23 is arranged on the counterweight block 20, the friction between the counterweight block 20 and the chute 15 is far less than the gravity of the counterweight block 20, the spring 14 restores the deformation to reset the scraper 17.

[0038] The sieve plate 13 close to the collecting box 12 is provided with an inclined plate, which functions to prevent the raw material from sliding out from both sides of the inclined plate due to horizontal shaking during sieving, and the inclined surface is beneficial to the raw material on the sieve plate 13 falling into the collecting box 12 when the scraper 17 pushes the raw material on the sieve plate 13 into the collecting box 12.

[0039] The above has made a detailed description of the embodiments of the utility model in combination with the drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled in the art without departing from the purpose of the utility model.
