Crushing and cooling device for calcium oxide

Abstract

The invention relates to a crushing and cooling device for calcium oxide. The crushing and cooling device comprises a supporting frame, wherein a conveying belt is arranged on the supporting frame, afeeding baffle is fixedly connected to the supporting frame, a feeding through groove is formed in the lower end of the feeding baffle, a supporting frame is fixedly connected to the supporting frame,a first crushing assembly is arranged on the supporting frame, a compression roller is abutted against the upper end of the conveying belt, a cooling tank is arranged on the one side of the supporting frame, a cooling pipeline communicates with the cooling tank, and the cooling pipeline is matched with a first crushing pipeline. According to the crushing and cooling device, when the calcium oxideis conveyed, the first crushing assembly can abut against the calcium oxide on the conveying belt to crush the calcium oxide, meanwhile, the cooling tank discharges cooling water into the first crushing assembly through the cooling pipeline, the calcium oxide can be subjected to a certain cooling effect when the calcium oxide is crushed, so that the production efficiency of the calcium oxide canbe improved.

Description

technical field [0001] The invention relates to the technical field of calcium oxide production equipment, in particular to a crushing and cooling device for calcium oxide. Background technique [0002] Calcium oxide is widely used in the manufacture of calcium carbide, soda ash, bleaching powder, refractory materials, calcium fertilizer, as a desiccant and soil improver; as an analytical reagent, as a flux for the manufacture of fluorescent powder; for tanning, wastewater purification; for construction Materials, metallurgical flux; the main raw material for the production of calcium hydroxide and various calcium compounds. [0003] The traditional calcium oxide production method mainly uses limestone as raw material. The calcination process adopts a shaft kiln. The limestone and solid fuel are mixed together or layered into the kiln for calcination, and the rest is the calcium oxide product. The equipment required by this production method is large in size, and it is easy...

AI Technical Summary

Problems solved by technology

After the calcium oxide is produced at high temperature, crushing and cooling are required. In the prior art, the crushing and cooling of calcium oxide are carried out separately, so it takes a long time to cool the lumpy calcium oxide before crushing , after pulverization, it is difficult to cool the calcium oxide powder, so whether it is cooled before or after pulverization, the cooling efficiency is not high
