Technical Field

[0001] This utility model relates to the field of photovoltaic semiconductor technology, and in particular to a raw material washing device for processing granular silicon. Background Technology

[0002] Processed granular silicon is a material used in the photovoltaic semiconductor industry. During pretreatment, the raw materials need to be washed with water to remove impurities and ensure the purity and product quality of the subsequent granular silicon preparation process. During washing, the water is usually soaked and stirred. Stirring causes the water to flow and wash the surface of the raw materials, dissolving soluble impurities and removing attached dust. When stirring, a unidirectional stirring method is generally used, which can easily lead to a regular water flow and a single washing force on impurities, which can affect the washing effect on the raw materials. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the regularity of water flow, the limited scouring force for impurities, and the resulting impact on the scouring effect on raw materials. Therefore, this invention proposes a raw material washing device for processing granular silicon.

[0007] Preferably, the upper end of the cleaning tub is fixedly connected to two handles.

[0008] Preferably, a filter plate is fixedly connected to the lower inner wall of the cleaning tub, and a plurality of support columns are abutted against the lower surface of the filter plate, with the lower ends of the plurality of support columns being fixedly connected to the base.

[0015] A protective shell 5 is fixedly connected to the support part 18. The protective shell 5 and the support part 18 form a sealed space. The sealed space protects the gear 15 and rack 16 and prevents them from being exposed. A first hydraulic cylinder 3 is fixedly connected to the upper surface of the protective shell 5. The upper end of the first hydraulic cylinder 3 is fixedly connected to the base 1 through the connecting frame 2. By extending and retracting the first hydraulic cylinder 3, the protective shell 5 is moved so as to remove the rotating shaft 14 and the stirring roller 13 from the cleaning tank 10 and take out the raw materials in the cleaning tank 10.

[0016] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, connecting sleeves 9 are fixedly connected at equal intervals around the lower circumference of the cleaning tub 10. Each of the multiple connecting sleeves 9 has a fixing post 8 inserted into it, and each of the multiple fixing posts 8 is fixedly connected to the base 1. By using the connecting sleeves 9 and the fixing posts 8, the cleaning tub 10 is limited, preventing the cleaning tub 10 from rotating during cleaning. At the same time, external threads can be provided on the fixing posts 8, and the connecting nut abuts against the connecting sleeve 9 to enhance the limiting effect on the cleaning tub 10.

[0017] Two handles 4 are fixedly connected to the upper end of the washing tank 10. The handles 4 are used to lift and move the washing tank 10, and to pour out the raw materials in the washing tank 10, so as to facilitate the removal of the raw materials.

[0018] Example 3: Reference Figure 2-3 In another preferred embodiment of this utility model, based on embodiment 2, a filter plate 11 is fixedly connected to the lower inner wall of the washing tub 10. The lower surface of the filter plate 11 abuts against a plurality of support columns 12. The lower ends of the plurality of support columns 12 are all fixedly connected to the base 1. The filter plate 11 is used to support the raw material. Impurities are discharged from the leakage hole with the water flow so that the impurities are separated from the raw material after washing. The support columns 12 support the filter plate 11 to prevent the filter plate 11 from collapsing.

[0019] Example 4: Reference Figure 1-3As another preferred embodiment of this utility model, based on embodiment 3, a drain box 6 is fixedly connected to one side of the base 1, a drain pipe 19 is connected to the lower end of the drain box 6, a valve 7 is connected to the lower end of the cleaning bucket 10, the lower end of the valve 7 extends into the drain box 6, and the drain pipe 19 is connected to an external drain pipe so that after cleaning, the valve 7 can be opened to drain the water in the cleaning bucket 10.

[0020] During operation, the raw materials are placed into the cleaning tank 10. The first hydraulic cylinder 3 extends, placing the stirring roller 13 into the cleaning tank 10. Cleaning fluid is added, and the second hydraulic cylinder 17 extends and retracts, causing the rack 16 to reciprocate. The rack 16 drives the gear 15 to rotate in both directions, thereby causing the rotating shaft 14 to rotate in both directions, which in turn drives the water flow to switch directions to rinse the raw materials. After the operation is completed, the valve 7 is opened, and water and impurities flow through the filter holes to the bottom of the cleaning tank 10 and are finally discharged from the valve 7. To ensure the cleaning effect, the cleaning can be repeated multiple times. When it is necessary to remove the raw materials, two workers lift the handle 4 to disengage the connecting sleeve 9 from the fixing post 8, so that the cleaning tank 10 can be moved and the raw materials inside the cleaning tank 10 can be poured out.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
