Description

Technical Field

[0001] The utility model relates to the technical field of particle material cleaning, in particular to a pickling device for particle materials. Background Art

[0002] The silicon ingot forming process uses fine-grained material as raw material. Fine-grained material is obtained by refining large-grained material. During the refining process, the large-grained material needs to be crushed in a crushing device. During the crushing process, some of the fine-grained material will adhere to the metal wear debris from the crushing equipment. The metal wear debris will contaminate the fine-grained material. If the metal wear debris is not removed, the silicon ingot will eventually fail. The existing operation method is to place the fine-grained material on a tray and then soak the tray in a pool of acidic solution for a period of time. The fine-grained material on the tray cannot be stacked or turned. This not only reduces work efficiency but also fails to fully remove the metal wear debris on the fine-grained material.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0024] See Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A pickling device for granular materials, comprising a pickling box 1, a pickling bottom plate 2, a pickling conveying plate 3, a blocking plate 4, a pickling liquid nozzle 5 and a vibrating conveying frame, wherein the pickling box 1 is fixedly arranged on the vibrating conveying frame, the pickling bottom plate 2 is horizontally sealed and fixedly arranged on the inner wall of the pickling box 1, the pickling conveying plate 3 is inclined and sealed and fixedly arranged on the inner wall of the pickling box 1 and the lower end is sealed and fixedly connected to the end of the pickling bottom plate 2, a feed port 6 is provided between the pickling bottom plate 2 and the top of the pickling box 1, and the pickling liquid is fed to the pickling box 1. A discharge port 7 is provided between the pickling conveyor plate 3 and the top of the pickling tank 1. A first pickling liquid outlet hole 8 is provided on the pickling bottom plate 2. A baffle plate 4 is sealed and fixedly installed on the pickling bottom plate 2. The baffle plate 4 is positioned between the first pickling liquid outlet hole 8 and the pickling conveyor plate 3. Both ends of the baffle plate 4 are sealed and fixedly connected to the inner wall of the pickling tank 1. A second pickling liquid outlet hole 9 is provided on the bottom of the pickling tank 1. A pickling liquid nozzle 5 is provided on the top of the pickling tank 1, which cooperates with the upper end of the pickling conveyor plate 3. The upper end of the pickling conveyor plate 3 extends to the outside of the pickling tank 1. A discharge pipe 13 is sealed and fixedly installed on the second pickling liquid outlet hole 9. Within the pickling tank 1, a cleaning pool is formed by the pickling bottom plate 2, pickling conveyor plate 3, and baffle plate 4. Granular material enters the cleaning pool directly for pickling. The pickled material is then transported to the next device via the pickling conveyor plate 3. The pickling liquid nozzle 5 is conventional and functions to transport and spray the pickling liquid. After flowing over the baffle plate 4, the used pickling liquid enters the bottom of the pickling tank 1 through the first pickling liquid outlet 8 and is then recycled through the second pickling liquid outlet 9 and the discharge pipe 13. A vibrating conveyor frame supports the pickling tank 1, vibrating it and transporting material via the pickling conveyor plate 3. The pickling solution used is conventional.

[0026] In some embodiments, a first dividing strip 10 is sealedly mounted on the pickling bottom plate 2, a second dividing strip 11 is sealedly mounted on the pickling conveying plate 3 and is sealed and fixedly connected to the first dividing strip 10, and the first dividing strip 10 is sealed and fixedly connected to the blocking plate 4. The provision of the first dividing strip 10 and the second dividing strip 11 facilitates better cleaning and conveying of materials, preventing them from being concentrated and stacked, resulting in ineffective cleaning. The first dividing strip 10 and the second dividing strip 11 disperse the materials between adjacent first dividing strips 10, or between the first dividing strip 10 and the inner wall of the pickling tank 1, for thorough cleaning.

[0027] In some embodiments, two necking plates 12 are sealed and fixedly provided on both sides of the upper end of the pickling conveying plate 3. The two necking plates 12 are symmetrically arranged and sealed and fixedly connected to the inner wall of the pickling tank 1. The provision of the necking plates 12 makes the material outlet smaller, so that the material outlet can be extended into the next equipment, reducing the intermediate transportation links.

[0028] In some embodiments, the vibrating conveyor frame includes a vibrating conveyor motor 14, a fixed bracket 15, a fixed lug 16, a buffer seat 17, and a limit bolt 18. The vibrating conveyor motor 14 is fixedly arranged on the pickling box 1 at an angle. The fixed lug 16 is fixedly arranged on the pickling box 1 and connected to the fixed bracket 15 via a limit bolt 18. The buffer seat 17 is sleeved on the limit bolt 18. Two vibrating conveyor motors 14 are symmetrically arranged on both sides of the pickling box 1. The vibrating conveyor motor 14 is a motor in the prior art. Under the action of the vibrating conveyor motor 14, the material is conveyed from the feed port 6 on the pickling box 1 to the discharge port 7. The fixed bracket 15 is used to install the pickling box 1 via the fixed lug 16, the buffer seat 17, and the limit bolt 18. During the operation of the vibrating conveyor motor 14, the buffer seat 17 acts as a buffer to prevent direct collision between the fixed lug 16 and the fixed bracket 15. The effect of the limiting bolt 18 is to limit the moving distance between the fixing lug 16 and the fixing bracket 15, and is used to install the buffer seat 17 and also prevent the buffer seat 17 from falling off. Under the most used condition of the vibration conveying motor 14, the granular material is also turned over during the movement.

[0029] In some embodiments, the cushion seat 17 is mounted on the fixed bracket 15 via a height adjustment component, and the lower end of the limit bolt 18 is mounted on the height adjustment component. The height adjustment component includes an upper adjustment plate 19, a lower adjustment plate 20, and adjustment bolts 21. The lower adjustment plate 20 is fixed to the fixed bracket 15. The upper adjustment plate 19 is fixed to the lower adjustment plate 20 via adjustment bolts 21. The limit bolt 18 is mounted on the upper adjustment plate 19. The upper and lower adjustment plates 19, 20 are connected by four sets of adjustment bolts 21. Among them, the lower adjusting disk 20 is fixed on the upper end of the fixed bracket 15, and four adjusting bolts 21 are arranged between the upper adjusting disk 19 and the lower adjusting disk 20. Under the action of the adjusting bolts 21, the distance between the upper adjusting disk 19 and the lower adjusting disk 20 can be adjusted. Four height adjustment components are arranged between the pickling box 1 and the fixed bracket 15, so that the height of the pickling box 1 can be adjusted. The lower end of the buffer seat 17 is directly placed on the upper adjusting disk 19, and through holes are provided on the fixed support ear 16 and the adjusting disk 19. The limiting bolt 18 can slide in the through holes on the fixed support ear 16 and the adjusting disk 19, and the limiting bolt 18 will not detach from the fixed support ear 16 and the adjusting disk 19.
