Description

Technical Field

[0001] This utility model relates to the technical field of silicon powder purification, and specifically to a mixing device for silicon powder purification. Background Technology

[0002] In recent years, a great deal of research has been conducted on the purification process of microsilica powder both at home and abroad. At present, the main purification methods include simple physical purification methods and chemical purification methods that are currently under research, including flocculation purification, calcination decarbonization, water flow classification purification, wet purification and acid purification, etc.

[0003] During purification, it is often necessary to mix the raw materials with the solution. Existing mixing devices for silica powder purification do not have a dispersion structure for adding silica powder. As a result, the raw materials are added and put into the mixing tank in a concentrated manner, which can easily cause the raw materials to clump together. This is not only detrimental to subsequent mixing processes, but also increases the workload of the stirring components and reduces mixing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixing device for silicon powder purification, which can solve the following problems:

[0005] Existing mixing devices for silica powder purification do not have a dispersion structure for silica powder addition. As a result, the raw materials are concentrated in the mixing tank after addition, which easily causes the raw materials to clump together, which is not conducive to subsequent mixing and processing, and increases the workload of the stirring components, reducing mixing efficiency.

[0006] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0007] A mixing device for purifying silicon powder includes a main body. A liquid inlet pipe is fixedly connected to the bottom outer side of the main body, and a material guiding assembly is fixedly connected to the top of the main body. A material distributing assembly is embedded in the inner side of the material guiding assembly. The material guiding assembly includes a surrounding ring seat and a material guiding bottom cover fixedly connected. A feeding cover is fixedly connected to the outer side of the surrounding ring seat. A feeding port is opened on the surface of the surrounding ring seat, and a guiding port is opened on the surface of the material guiding bottom cover. The material distributing assembly includes a drive mechanism, a transmission rod, an upper guide plate, a connecting arm, a lower positioning plate, and a stirring shaft connected sequentially from top to bottom. A material guiding scraper is fixedly connected to the outer side of the upper guide plate. The connecting arm is simultaneously sleeved with the stirring shaft. A blocking sleeve is fixedly connected to the top of the lower positioning plate.

[0008] Furthermore, the filling hood is vertically arranged in an "L" shape, and it is connected to the surrounding ring seat through the filling port. The filling port is opened in a strip shape along the rear surface of the surrounding ring seat.

[0009] Furthermore, the material guide cover is a hemispherical cover, and the guide port has two sets of strips along its front and rear surfaces.

[0010] Furthermore, the transmission rod is vertically arranged in an "L" shape, with its bottom outer end eccentrically connected to the surface of the upper guide plate. The upper guide plate and the lower positioning plate are arranged vertically, and the outer side of the lower positioning plate is fixedly connected to the inner side of the guide bottom cover.

[0011] The guide scrapers are vertically arranged along the outer edge of the upper guide plate, with two sets distributed adjacent to each other. The guide scrapers are also located inside the surrounding ring seat.

[0012] Furthermore, there are three sets of connecting arms, which are arranged horizontally in a "Z" shape. The top of the connecting arm is movably connected to the bottom surface of the upper guide plate through the shaft, and the bottom is connected to the top of the stirring shaft. There are three sets of stirring shafts, and their tops are simultaneously movably connected through the lower positioning plate.

[0013] Furthermore, three sets of stirring shafts are arranged along the triangular position, and multiple sets of stirring fans are evenly distributed on their surface.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] See Figure 1-7 As shown, a mixing device for silicon powder purification includes a main body 1. A liquid inlet pipe 2 is fixedly connected to the bottom outer side of the main body 1. A material guiding assembly 3 is fixedly connected to the top of the main body 1. A material distributing assembly 4 is embedded in the inner side of the material guiding assembly 3. The material guiding assembly 3 includes a surrounding ring seat 5 and a material guiding bottom cover 8 fixedly connected. A feeding cover 6 is fixedly connected to the outer side of the surrounding ring seat 5. A feeding port 7 is opened on the surface of the surrounding ring seat 5. A guiding port 9 is opened on the surface of the material guiding bottom cover 8. The material distributing assembly 4 includes a drive mechanism 10, a transmission rod 16, an upper guide plate 11, a connecting arm 15, a lower positioning plate 13, and a stirring shaft 14 connected sequentially from top to bottom. A material guiding scraper 12 is fixedly connected to the outer side of the upper guide plate 11. The connecting arm 15 is simultaneously sleeved with the stirring shaft 14. A blocking sleeve 17 is fixedly connected to the top of the lower positioning plate 13.

[0030] In this embodiment of the utility model, the filling cover 6 is vertically arranged in an "L" shape. It is connected to the surrounding ring seat 5 through the filling port 7. The filling port 7 is opened in a strip shape along the rear surface of the surrounding ring seat 5. The material guiding cover 8 is set in a hemispherical shape. The conveying port 9 is opened in two sets in a strip shape along its front and rear surfaces. The addition of silicon powder is achieved by the filling cover 6 in conjunction with the filling port 7. The dispersion and conveying of silicon powder is achieved by the material guiding cover 8 and the conveying port 9 on its surface.

[0031] The transmission rod 16 is vertically arranged in an "L" shape, with its bottom outer end eccentrically connected to the surface of the upper guide plate 11. The upper guide plate 11 and the lower positioning plate 13 are arranged vertically. The outer side of the lower positioning plate 13 is also fixedly connected to the inner side of the material guide cover 8. The material guide scraper 12 is vertically arranged along the outer edge of the upper guide plate 11, with two sets arranged adjacently. The material guide scraper 12 is also located inside the surrounding ring seat 5. There are three sets of connecting arms 15, which are arranged horizontally in a "Z" shape. The top of the connecting arm 15 is movably sleeved with the bottom surface of the upper guide plate 11 through the shaft, and the bottom end is sleeved with the top of the stirring shaft 14. There are three sets of stirring shafts 14, with their top ends movably passing through the lower positioning plate 13. The stirring shaft 14 is arranged along a triangular pattern. The device consists of multiple sets of stirring fans evenly distributed on its surface. The blocking sleeve 17 protrudes along the edge of the lower positioning plate 13, and its top edge extends outward in an arc shape. The transmission rod 16, which is eccentrically connected to the upper guide plate 11, drives the upper guide plate 11 to rotate and adjust. The upper guide plate 11, in conjunction with the connecting arm 15, drives the stirring shaft 14 to rotate and adjust. The guide scraper 12 scrapes and discharges the silicon powder concentrated inside the surrounding ring seat 5. The stirring shaft 14 mixes the silicon powder in the main body 1 with the external additive liquid. The lower positioning plate 13, in conjunction with the blocking sleeve 17, forms a sandwich inside the surrounding ring seat 5, which is beneficial for the addition and discharge of silicon powder.

[0032] Silicon powder flows out from the feeding port 7 through the feeding hood 6 to the position between the surrounding ring seat 5 and the blocking sleeve 17. At this time, the drive mechanism 10 is started, and the upper guide plate 11 is driven to rotate eccentrically through the transmission rod 16. The rotation of the upper guide plate 11 drives the guide scraper 12 at its edge to rotate along the inner side of the surrounding ring seat 5, pushing the silicon powder between the surrounding ring seat 5 and the blocking sleeve 17 to the guide port 9 and dispersing it into the main body 1 of the device. At the same time, the eccentric rotation of the upper guide plate 11 drives the three sets of stirring shafts 14 to rotate simultaneously under the action of the connecting arm 15, mixing and stirring the dispersed silicon powder and the external additive liquid together.

[0033] In this device, the drive mechanism 10 can be set as a belt drive mechanism, which is existing publicly available technology and will not be described in detail here. At the same time, when adding external additive liquid, such as water or acidic solution, to the main body 1 of the device, it can be added directly through the liquid inlet pipe 2.

[0034] The main body of the device 1 is equipped with an air compressor and its associated pipelines, which are the basic components of the silicon powder purification and mixing device. This is well known to those skilled in the art and will not be described in detail here.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
