Abstract
Description
Technical Field
[0001] This utility model patent belongs to the field of industrial silicon production technology, specifically relating to a silica raw material sorting system. Background Technology
[0002] Silica, as the main raw material for the production of metallic silicon, inevitably contains a certain proportion of impurities during mining. These impurities negatively impact production costs and product quality, necessitating sorting. Currently, manual sorting is used, where workers visually inspect and manually select impurities next to the conveyor belt. This method has the following problems: 1. Impurities with low silica content will result in low silicon conversion rates during production, increasing costs. 2. Impurities with high impurity content will introduce more impurities during production, lowering product quality. 3. Manual sorting relies on visual inspection, which is affected by the speed of human judgment, leading to uncertainties in accuracy. 4. Manual sorting involves handling materials by hand next to the rotating conveyor belt, posing a safety hazard of mechanical injury. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a silica raw material sorting system that improves the accuracy of identification and sorting, and enhances production safety.
[0004] This utility model discloses a silica raw material sorting system, which includes a drum washing machine, a material conveyor belt, a plow-type distributor, a receiving hopper, and a color sorter. The discharge end of the drum washing machine is located above the feed end of the material conveyor belt. The plow-type distributor is fixedly installed above the material conveyor belt. The receiving hopper is fixedly installed below the outer side of the material conveyor belt on both sides of the plow-type distributor. The color sorter is fixed below the receiving hopper. The discharge port of the receiving hopper is located above the feed port of the color sorter.
[0005] Furthermore, it also includes a stone conveyor belt, a stone storage bin, a silica conveyor belt, and a silica storage bin; the stone discharge port of the color sorter is connected to the feed end of the stone conveyor belt via a stone chute; the discharge end of the stone conveyor belt is located above the feed inlet of the stone storage bin; the silica discharge port of the color sorter is connected to the feed end of the silica conveyor belt via a silica chute; the discharge end of the silica conveyor belt is located above the feed inlet of the silica storage bin.
[0006] Advantages of this utility model:
[0007] This utility model discloses a silica raw material sorting system with a simple connection structure that is easy to implement. A plow-type distributor divides the material on the conveyor belt to color sorters on both sides for sorting, achieving automated sorting of silica and impurities without manual selection. This improves the accuracy and efficiency of identification and sorting, thereby reducing the content of impurities entering the furnace, increasing the silicon conversion rate, and lowering production costs. Simultaneously, it reduces impurity elements entering the furnace, improving product quality indicators. Furthermore, the elimination of manual selection effectively isolates personnel and machines, thus improving production safety. Attached Figure Description

[0012] The present invention will be further described in detail below through embodiments.
[0013] Example: Figure 1-2 As shown, a silica raw material sorting system includes a drum washing machine 1, a material conveyor belt 2, a plow-type distributor 3, a receiving hopper 4, a color sorter 5, a mixed stone conveyor belt 6, a mixed stone storage bin 7, a silica conveyor belt 8, and a silica storage bin 9. The discharge end of the drum washing machine 1 is located above the feed end of the material conveyor belt 2. The plow-type distributor 3 is fixedly installed above the material conveyor belt 2. The receiving hopper 4 is fixedly installed below the outer side of the material conveyor belt 2 on both sides of the plow-type distributor 3. The color sorter 5 is fixedly installed below the receiving hopper 4. The discharge port of the receiving hopper 4 is located above the feed port of the color sorter 5. The color sorter 5 is manufactured by Hefei Mingde Optoelectronic Technology Co., Ltd., and its model is MAI-XD-6L.
[0014] The waste stone discharge port of the color sorter 5 is connected to the feed end of the waste stone conveyor belt 6 via a waste stone chute 10; the discharge end of the waste stone conveyor belt 6 is located above the feed port of the waste stone storage bin 7; the silica discharge port of the color sorter 5 is connected to the feed end of the silica conveyor belt 8 via a silica chute 11; the discharge end of the silica conveyor belt 8 is located above the feed port of the silica storage bin 9.
[0015] Working principle: The material washed by the drum washing machine 1 is sent to the material conveyor belt 2. The running material conveyor belt 2 carries the material to the plow-type distributor 3. The plow-type distributor 3 distributes the material on the material conveyor belt 2 into the receiving hoppers 4 on both sides. The material in the receiving hoppers 4 falls into the inlet of the color sorter 5 for color sorting. The silica is pure in color, including white, grayish-white, yellowish-gray, black, and red, while the impurities are mixed in color. The color sorter 5 effectively separates the silica and impurities. The silica falls onto the silica conveyor belt 8 through the silica chute 11, and then... The operating silica conveyor belt 8 transports silica to the silica storage bin 9 for stacking, and then to the next process. Meanwhile, miscellaneous stones fall through the miscellaneous stone chute 10 onto the miscellaneous stone conveyor belt 6, and are subsequently transported to the miscellaneous stone storage bin 7. This achieves automated sorting of silica and miscellaneous stones, eliminating the need for manual selection and improving the accuracy and efficiency of identification and sorting. This reduces the amount of miscellaneous stones entering the furnace, increases the silicon conversion rate, and lowers production costs. Simultaneously, it reduces impurities entering the furnace, improving product quality indicators. Furthermore, the elimination of manual selection and sorting effectively isolates personnel and machines, thereby improving production safety.
[0016] The above are preferred embodiments of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
