DETAILED DESCRIPTION

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following description, in conjunction with the accompanying drawings, describes the molten silicon micropowder processing and filtration device according to an embodiment of the present invention.

[0024] like Figures 1-5 As shown, the molten silicon micro powder processing and filtering device of this utility model embodiment may include a central rotating cylinder 10, a feed pipe 30, a discharge pipe 40, a rotating frame 50, and a rotating shaft 60.

[0025] The transfer cylinder 10 has a partition 11 inside. The partition 11 is a frustum-shaped structure that is narrower at the top and wider at the bottom. The partition 11 divides the interior of the transfer cylinder 10 into an upper cavity 101 and a lower cavity 102. The lower side of the partition 11 has a through hole 111. The upper cavity 101 and the lower cavity 102 are connected through the through hole 111. The upper cavity 101 has a discharge port 1011 on one side. The inner side of the discharge port 1011 has an arc-shaped filter screen 20. The bottom of the lower cavity 102 is conical, and an outlet 103 is located in the middle of its bottom.

[0026] The feed pipe 30 passes through the central rotating cylinder 10 and is closed at the bottom. The feed pipe 30 has a notch 31 on its lower side, which faces the discharge port 1011. The discharge pipe 40 is located outside the discharge port 1011.

[0027] The rotating frame 50 may include a collar 51 and multiple first rotating plates 52. The collar 51 is movably sleeved on the outside of the feed pipe 30. The top of the partition 11 is provided with a mounting groove 112, and the collar 51 is movably disposed inside the mounting groove 112. The mounting groove 112 can limit the position of the collar 51. The multiple first rotating plates 52 are circumferentially disposed on the outside of the collar 51, and the outer sides of the first rotating plates 52 are in sliding contact with the outer wall of the feed pipe 30, the top surface of the partition 11, and the inner wall of the upper cavity 101, respectively. The first rotating plates 52 are also in sliding contact with the arc-shaped filter screen 20.

[0028] It should be noted that, in this embodiment, the two adjacent first rotating plates 52, the upper cavity 101, and the feed pipe 30 together constitute the channel 80, and multiple channels 80 are formed within the upper cavity 101. When the two sides of the channel 80 are connected to the notch 31 and the discharge port 1011 respectively, the material in the feed pipe 30 can smoothly pass through the corresponding channel 80 and enter the discharge pipe 40. During this process, the arc-shaped filter screen 20 can fully filter the passing material, and during the rotation of the rotating frame 50, the two adjacent channels 80 can simultaneously undertake the material transport operation.

[0029] The rotating shaft 60 movably penetrates the partition plate 11 and is located inside the sleeve ring 51. The top end of the rotating shaft 60 extends into the feeding pipe 30 and is provided with an accelerating part. The accelerating part can include a plurality of second rotating plates 61 arranged in the circumferential direction. The plurality of second rotating plates 61 are arranged outside the rotating shaft 60 and are in sliding contact with the inner wall of the feeding pipe 30. The top surface of the second rotating plate 61 is in sliding contact with the upper inner wall of the notch 31. When the second rotating plate 61 rotates, it can accelerate the material in the feeding pipe 30 and convey it into the corresponding channel 80, so that the material can quickly pass through the arc-shaped filter screen 20 and enter the discharging pipe 40. The accelerating part helps to improve the conveying efficiency of the material, thereby effectively improving the filtering efficiency and effect of the material.

[0030] The driving assembly 70 is arranged in the mounting groove 112. The driving assembly 70 can include a motor 71 and two driving wheels 72. The two driving wheels 72 are drivingly connected and are respectively connected with the motor 71 and the rotating shaft 60. The bottom of the sleeve ring 51 is provided with a tooth ring 511. An incomplete gear 722 is arranged on one of the driving wheels 72 through a connecting shaft 721. The incomplete gear 722 is in meshing connection with the tooth ring 511. The motor 71 drives the driving wheel 72 connected therewith to rotate, thereby causing the synchronous rotation of the other driving wheel 72. This linkage effect promotes the operation of the plurality of second rotating plates 61 and the crushing knife group 62 of the rotating shaft 60. At the same time, the incomplete gear 722 and the connecting shaft 721 also rotate. In particular, when the incomplete gear 722 is in meshing connection with the tooth ring 511, it can effectively drive the sleeve ring 51 to rotate synchronously. When the incomplete gear 722 is separated from the tooth ring 511, the sleeve ring 51 remains stationary.

[0031] It should be noted that the driving assembly 70 arranged in the embodiment can not only drive the rotating shaft 60 to rotate, but also can realize the intermittent rotation of the rotating frame 50. This mechanism promotes the intermittent rotation of the sleeve ring 51 and the plurality of first rotating plates 52. Such a design ensures that the plurality of channels 80 can sequentially convey the material in turn. In addition, during the rotation of the first rotating plate 52, the surface of the arc-shaped filter screen 20 can be scraped and cleaned, and the material adhered thereto can be removed. When the channel 80 rotates and is in communication with the through hole 111, the material intercepted by the arc-shaped filter screen 20 in the channel 80 and the material scraped by the first rotating plate 52 can smoothly enter the lower cavity 102 through the through hole 111. Then, the crushing knife group 62 quickly intervenes to crush the material in time, thereby completing the efficient operation of the whole process.

[0032] It should be noted that the two drive wheels 72 described in this embodiment can be connected through gear engagement, belt transmission, etc., so as to ensure that the two drive wheels 72 can rotate synchronously.

[0033] Specifically, in the actual filtering operation of the molten silicon micro-powder material, the relevant personnel first start the motor 71, and then pour the material to be filtered into the feeding pipe 30. The material is first accelerated to the corresponding channel 80 through the rotation of the plurality of first rotating plates 52, and then the material is filtered through the arc-shaped filter screen 20, wherein the qualified material smoothly enters the discharging pipe 40, and the unqualified material is intercepted in the corresponding channel 80. With the continuous rotation of the rotating frame 50 in an intermittent manner, the plurality of channels 80 can sequentially undertake the transmission task of the material. In this process, the first rotating plate 52 not only assists the transmission of the material, but also plays a role in scraping and cleaning the surface of the arc-shaped filter screen 20, effectively removing the material residues attached thereto.

[0034] The channels 80 that accumulate unqualified materials will gradually rotate away from the arc-shaped filter screen 20 and can be in communication with the through hole 111. At this time, whether the material intercepted by the arc-shaped filter screen 20 or the material scraped by the first rotating plate 52 can smoothly enter the lower cavity 102 through the through hole 111. Then, the crushing knife group 62 quickly intervenes to timely and efficiently crush the material. Finally, the crushed material can be discharged through the outlet 103.

[0035] In summary, the molten silicon micro-powder processing and filtering device of the embodiment of the present application can effectively transfer the unqualified material accumulated between the adjacent two first rotating plates to the lower cavity for further crushing treatment by controlling the rotation of the rotating frame. At the same time, the rotating action of the first rotating plate can also clean the arc-shaped filter screen, effectively prevent the arc-shaped filter screen from being blocked, ensure the continuity of the filtering operation, and improve the filtering efficiency. In addition, the device can also reduce the workload of material transfer, which plays a positive role in improving the processing quality of the molten silicon micro-powder.
