Description

Calcium sulfate filter-pressing crushing conveying production line

Technical Field

The utility model relates to the field of calcium sulfate production equipment, in particular to a calcium sulfate press filtration crushing conveying production line.

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. And then, inputting the calcium sulfate solution into a filter press for extrusion drying, crushing the dried blocky calcium sulfate by a crusher, outputting a stacker, and transporting to a drying station by a forklift. The calcium sulfate output by the existing filter press is directly piled after being conveyed by the belt conveyor, a baffle is absent between a material pile and the conveyor, and when calcium sulfate raw materials are transported by a forklift, calcium sulfate powder easily enters the lower part of the conveyor, so that the production environment of a factory is influenced. In the production, clean water is firstly required to be sent into a filter press to clean the calcium sulfate raw material, the washed water is not effectively utilized, and the washed water is often directly discharged as sewage, so that the water consumption of a production line is large, and the production cost is high. There is a need for a washing wastewater tank that can fully utilize the washing water. 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.
