Description

Calcium sulfate conveying and drying system

Technical Field

The utility model relates to the field of calcium sulfate production equipment, in particular to a calcium sulfate conveying and drying system.

Background

Currently, in a calcium sulfate production line, a calcium sulfate raw material containing slag needs to be neutralized by adding acid and water to remove slag in the calcium sulfate raw material, and the pH is neutralized from 14 to about 7. Then, the calcium sulfate solution is input into a filter press for extrusion drying, and the dried blocky calcium sulfate is crushed by a crusher, is output to be piled up, is transported to a hopper by a forklift, and is then sent to be dried by a conveyor. The hopper before the stoving station lacks the curb plate that is used for spacing to the forklift when the forklift feeding, leads to the scraper bowl of forklift to strike easily on the hopper, with hopper striking deformation, influences the life of hopper. The hopper is easy to spill calcium sulfate raw material powder during feeding to pollute the production environment of factories. When the existing dryer is used for drying, the bottom of the existing dryer is heated and dried through a jacket, and the drying speed is low; when the dryer is fed, dust is easy to generate due to the large drop of raw materials, and the production environment of factories is polluted.
