Chain belt type granulator for rapid one-step molding of high temperature liquid calcium carbide

Abstract

The invention provides a chain belt type granulator for rapid one-step molding of high temperature liquid calcium carbide. The chain belt type granulator is provided with a conveying chain belt, which is provided with a plurality of calcium carbide dies and a calcium carbide scraping plate. Each of the calcium carbide dies is formed by back-to-back arrangement of two identical half dies. The calcium carbide scraping plate is used for strickling the high temperature liquid calcium carbide constantly, so that the high temperature liquid calcium carbide uniformly flows into the calcium carbide dies, and along with continuous conveying by the conveying chain belt, the high temperature liquid calcium carbide in the calcium carbide dies quickly cools into a solid calcium carbide block. The chain belt type granulator provided by the invention can efficiently break calcium carbide, omits a breaking process in a downstream PVC production process, avoids formation of powder caused by manual breaking of calcium carbide, and greatly reduces the waste of materials. In addition, as the volume of the calcium carbide block is greatly reduced, the surface area is increased, the heat dissipation rate is quickened, the calcium carbide cooling time is shortened, and workshop manpower and material resources, and floor occupation are saved.

Description

technical field [0001] The invention relates to a device for molding calcium carbide, in particular to a chain-belt granulator for rapid one-time molding of high-temperature liquid calcium carbide. Background technique [0002] Calcium carbide, namely calcium carbide, is an inorganic compound, colorless crystal, and is an important basic chemical raw material, mainly used to produce acetylene gas, and also used in organic synthesis, oxyacetylene welding, etc. [0003] The cooling and crushing of calcium carbide finished products is a problem that has plagued calcium carbide enterprises for a long time. For the traditional process of cooling and crushing of calcium carbide products, please refer to figure 1 , figure 1 It is a schematic flow chart of the traditional process. In the traditional process, the temperature of the calcium carbide melt is as high as 1800°C to 2200°C. Multiple cooling pots 18 are placed at the calcium carbide exit 19. After the calcium carbide melt ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, in the traditional cooling and crushing process of calcium carbide, there are the following defects: (1) a large amount of waste heat loss of high-temperature calcium carbide is caused, and a large production space is occupied; It can be crushed after cooling for 22-26 hours; (3) The calcium carbide in the process of natural or strong wind cooling is placed in an open place, because the calcium carbide reacts violently immediately when it meets water, and there is a great safety hazard; (4) After cooling Calcium carbide lumps need to be broken manually. On the one hand, the crushing process will cause 15-25% powder loss, resulting in the loss of calcium carbide products; on the other hand, it also increases the input of manpower and material resources in the workshop.
