Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushing equipment, in particular to a metal silicon crushing device. Background Art
[0002] Metallic silicon, also known as crystalline silicon or industrial silicon, is used as an additive for non-ferrous alloys. Metallic silicon is a product smelted from quartz and coke in an electric furnace. The content of the main component silicon is about 98%. In the preparation process of high-purity silicon, purification is a necessary step. Existing purification methods include directional solidification, slag making, pickling and oxidation. Regardless of the purification method, the raw materials need to be crushed.
[0003] The existing crushers only have the function of one-time crushing. Silicon blocks that cannot be effectively crushed will be screened and sent to another crusher through a conveying device or sent to the same crusher through a lifting device for further crushing. Setting up multiple crushers will lead to high maintenance and use costs of the equipment. Due to the characteristics of the silicon blocks themselves, in order to effectively lift the silicon blocks without occupying too large an area, a chain bucket elevator is generally used. However, the price of the chain bucket elevator is relatively high, and the use and maintenance costs are also high. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
[0018] like Figure 1-Figure 4As shown, a metal silicon crushing device comprises a crushing box 1, a supporting wheel group 2, a rotary drum 3, a feed hopper 4, a guide plate 5 and a screen plate 6. The crushing box 1 is installed on the ground through four support columns 15. A feed port 11 is provided on the top of the crushing box 1. A pair of toothed rollers 7 are provided below the feed port 11 in the crushing box 1. A motor 8 for driving the toothed rollers 7 to rotate is provided outside the crushing box 1. The feed port 11 is connected to the feed hopper 4. The left side of the feed hopper 4 extends to the outside of the crushing box 1. A screen plate 6 is obliquely provided below the two toothed rollers 7 in the crushing box 1. The edge of the screen plate 6 is connected to the inner wall of the crushing box 1. The left side of the screen plate 6 is a low side and the right side is a high side. A silicon block outlet is provided on the left side wall of the crushing box 1 corresponding to the low side of the screen plate 6. 12. A guide plate 5 is obliquely arranged on the outer wall of the crushing box 1 below the silicon block outlet 12, and the left side of the guide plate 5 is the low side. The supporting wheel group 2 is fixed to the ground and located at the lower left side of the crushing box 1. The rotary drum 3 is horizontally mounted on the supporting wheel group 2, and the supporting wheel group 2 can drive the rotary drum 3 to rotate. Annular baffles 31 are fixedly connected to both axial ends of the rotary drum 3. The surface formed by the top opening of the feed hopper 4 horizontally passes through the two annular baffles 31. The left side of the guide plate 5 is arranged between the two annular baffles 31. A plurality of supporting plates 32 are evenly distributed on the inner circumferential wall of the rotary drum 3. The connection point between the supporting plate 32 and the inner circumferential wall of the rotary drum 3 is used as the tangent point.
