Description

Technical Field

[0001] This utility model relates to the field of silicon material processing technology, and in particular to a rapid screening device for high-purity metallic silicon materials. Background Technology

[0002] A search revealed that Chinese Patent CN220425915U discloses a silicon material screening device. Addressing the issue of insufficient sealing, which can lead to impurities entering the device during silicon material screening and thus affecting the purity of the silicon material and reducing its practicality, the patent improves sealing to prevent impurities from entering the device during screening, thereby ensuring the purity of the silicon material and enhancing the device's practicality.

[0003] While the aforementioned screening device is convenient for screening metallic silicon materials, the screening process in this device and in traditional technologies typically involves feeding material through a feed pipe located above the device. When the silicon material is fed onto the filter screen through the feed pipe, localized accumulation and arching can easily occur, while the material around the edges is less abundant. This results in uneven distribution of the material on the filter screen, which can lead to low screening efficiency due to the relatively thick material in some areas and mutual compression between the materials during screening.

[0010] Multiple springs are fixedly connected to both sides of the annular plate, with the springs fixedly connected to the inner wall of the annular plate and the springs sleeved on the outside of the limiting rod. A filter screen is fixedly connected inside the annular plate, and a vibration motor is fixedly installed on the lower surface of the annular plate.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, through the setting of the screening component, utilizes the shaking filter screen to facilitate screening of the fed materials. While the connecting rod revolves, it also facilitates the revolving of the arc-shaped push plate. The through groove in the arc-shaped push plate allows the material on the filter screen to pass through during the revolving motion. The continuous pushing action helps to flatten the material on the filter screen. Furthermore, the arc-shaped push plate helps to gather the material and push it, making it easier for the material to be evenly distributed on the filter screen and reducing the phenomenon of excessive local accumulation of material on the filter screen, which makes screening difficult.

This utility model utilizes the function of the insert plate and slot to facilitate the separation of the upper and lower barrels, thereby making it easier to inspect the wear of the internal filter screen and the arc-shaped push plate. At the same time, after separating the upper and lower barrels, it is also convenient to clean the impurities screened out by the filter screen. Attached Figure Description

[0032] The screening assembly includes two fixing blocks 7, which are fixedly connected to the outer sides of the lower barrel 4 respectively, so as to facilitate the installation of the arc rod 8 and fix the arc rod 8.

[0033] As attached Figure 3 As shown, an arc-shaped rod 8 is fixedly connected to the upper surface of the fixed block 7. Multiple slots are provided inside the arc-shaped rod 8 for the arc-shaped rod 8 to pass through. Multiple limiting rods 9 are slidably connected inside the arc-shaped rod 8 to limit the annular plate 11. A round block 10 is fixedly connected to one end of the limiting rod 9 to limit the limiting rod 9. The other end of the multiple limiting rods 9 is fixedly connected to the annular plate 11, which is hollow and ring-shaped, to facilitate the installation of the filter screen 13. Multiple springs 12 are fixedly connected to both sides of the annular plate 11. The multiple springs 12 are fixedly connected to the inner wall of the annular plate 11 to facilitate the generation of elastic force in the annular plate 11. The springs 12 are sleeved on the outside of the limiting rods 9 to facilitate the limiting rods 9 to limit the springs 12. The filter screen 13 is fixedly connected inside the annular plate 11 to facilitate the filtering of materials. A vibration motor 14 is fixedly installed on the lower surface of the annular plate 11 to output vibration force.

[0034] As attached Figure 5 As shown, an external gear ring 15 is rotatably connected between the upper barrel 1 and the barrel lid 2. A connecting rod 16 is fixedly connected to the inner wall of the external gear ring 15. Under the connection of the external gear ring 15, the rod rotates inside the upper barrel 1. An arc-shaped push plate 17 is fixedly connected to one end of the connecting rod 16. The push plate 17 is arc-shaped with an arc-shaped edge. Multiple through slots 18 are provided inside the arc-shaped push plate 17 to facilitate the passage of materials.

[0035] As attached Figure 4 As shown, a variable speed motor 19 is fixedly installed on one side of the upper bucket 1. A gear 20 is fixedly connected to the output end of the variable speed motor 19. The gear 20 is meshed with the external gear ring 15, which facilitates the rotation of the external gear ring 15. A protective shell 21 is fixedly connected to one side of the bucket lid 2. The protective shell 21 is placed outside the gear 20 and protects the gear 20. An insert plate 22 is fixedly connected to the lower surface of the connecting frame 6, which facilitates connection with the slot 25. A threaded hole 23 is opened on one side of the insert plate 22, which matches the thread of the bolt 26.

[0036] As attached Figure 6 As shown, both sides of the lower bucket 4 are fixedly connected to a base frame 24 to support the whole and facilitate connection with the upper bucket 1. The base frame 24 has a slot 25 inside to accommodate the insert plate 22. A bolt 26 passes through one side of the base frame 24 to fix the insert plate 22. The lower bucket 4 has a guide block 27 fixedly connected inside, and has a guideable inverted conical groove inside.

[0037] Working principle: During use, the controller starts the vibration motor 14 and the variable speed motor 19. The vibration motor 14 generates vibration force, which is transmitted to the annular plate 11 through its close contact with the plate. When the annular plate 11 is vibrated, it compresses the springs 12 on both sides, causing the springs 12 to rebound under the limit of the arc rod 8 at one end, increasing the vibration force of the annular plate 11. At the same time, the annular plate 11 also drives multiple limit rods 9 to slide inside the arc rod 8, facilitating the shaking of the filter screen 13. Then, the material is fed into the upper tank 1 through the feed pipe 3, allowing the material to move freely. The material is on the upper surface of the filter screen 13. The rotation of the output end of the variable speed motor 19 will drive the gear 20 to rotate. When the gear 20 drives the outer gear ring 15 to rotate, the outer gear ring 15 will drive the connecting rod 16 to revolve. The connecting rod 16 drives the arc-shaped push plate 17 to push the material on the surface of the filter screen 13. When the material is pushed by the arc-shaped push plate 17, the material piled in the middle will be hooked into the arc-shaped concave area. Then, through the through groove 18, the material can be spread on the upper surface of the filter screen 13 by the arc-shaped push plate 17 when it moves, reducing the accumulation of material.

[0038] After the material is filtered, the bolts 26 on both sides are unscrewed from the threaded holes 23, and then the connecting brackets 6 on both sides are lifted up, so that the connecting brackets 6 drive the insert plate 22 to disengage from the slot 25, thereby separating the upper barrel 1 from the lower barrel 4, thus cleaning the impurities filtered out on the filter screen 13, and allowing the wear of the filter screen 13 and the arc-shaped push plate 17 to be checked.

[0039] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
