Description

Technical Field

[0001] The utility model belongs to the technical field of industrial silicon production, and specifically relates to a pulverizing device for industrial silicon production. Background Art

[0002] Industrial silicon is also called metallic silicon. It is a product smelted from silica and carbonaceous reducing agent in a submerged arc furnace. The main component silicon element content is about 98% (in recent years, silicon with a Si content of 99.99% is also listed in metallic silicon), and the remaining impurities are iron, aluminum, calcium, etc. Due to its different uses, it is divided into various specifications. According to the content of iron, aluminum and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421.3303.3305, 2202, 2502, 1501.1101, etc. The additional products of metallic silicon include microsilicon fume, edge silicon, black silicon, metallic silicon slag, etc. Among them, microsilicon fume is also called silica fume, which is widely used in refractory and concrete industries.

[0003] In the process of industrial silicon production and manufacturing, a crushing device is needed to process it. For example, Chinese utility model patent CN210522761U discloses a new type of crushing device for industrial silicon production and manufacturing. By setting a lower pressure plate and a pushing mechanism, a process of briquetting the raw materials is added. The lower pressure plate is driven by the lower pressure cylinder, so that large pieces of raw materials are processed first, and the raw materials after briquetting are transported with the pushing mechanism, so that the subsequent crushing rollers crush the raw materials more thoroughly, ensuring a good crushing effect, and being able to crush the raw materials in an orderly manner, avoiding the blockage of the raw materials. Compared with the uneven crushing of large and small pieces of raw materials mixed together in the prior art, the crushing effect of this design is more superior; by setting up a wiping mechanism, the cleaning brush on the side plate is in direct contact with the side surface of the crushing roller, and the cleaning brush directly sweeps off the residue adhering to the surface of the crushing roller, which can be cleaned more effectively, ensuring a good cleaning effect and reducing the cleaning workload of the staff. It has high practicality. Compared with the prior art where the residue adhering to the crushing roller is difficult to clean, this design does not require manual cleaning, ensuring a good cleaning effect.

[0004] Although the above-mentioned prior art can pre-process large pieces of industrial silicon, each piece of industrial silicon needs to be pre-processed by the lower pressing plate, and some small pieces of industrial silicon still undergo the pre-processing process, thereby reducing the loading speed.
