Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a conveying device for calcium carbide processing. Background Technology

[0002] Calcium carbide (calcium carbide) is an important basic chemical raw material. Its processing usually involves the conveying and feeding of crushed materials. According to the patent authorization announcement number: CN217534466U, a raw material conveying device in the calcium carbide production process is disclosed. The device includes a material conveying device in the calcium carbide production process, which consists of a material receiving port, a discharge pipe, a reversible belt conveyor, a protective cover, an observation port, a top discharge port of the silo, and a feeding belt conveyor, arranged sequentially from top to bottom. The material receiving port has a discharge pipe; the reversible belt conveyor under the discharge pipe operates in two directions, left and right, respectively, to feed materials into the silo. Currently, the calcium carbide processing industry commonly uses belt conveyors and other devices to transfer crushed calcium carbide materials to the next process. However, in existing technologies, the crushed calcium carbide materials often have uneven particle sizes. If these materials of different particle sizes are directly mixed, conveyed, and fed into subsequent reaction equipment (such as generators), the larger calcium carbide particles can easily affect processing efficiency. Furthermore, calcium carbide materials have a certain degree of stickiness, especially when the air humidity is slightly high, making them prone to adhering to the surface of the conveyor belt. When the conveyor belt returns, they are likely to fall into the inside of the feed rack, affecting the normal operation of the conveyor belt. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0019] The specific implementation process of this utility model is as follows: In use, the raw material is put into the hopper 4.
