An automatic lifting and filtering product system for a dihydrate gypsum production line

Abstract

The invention provides an automatic lifting and filtering product system of a dihydrate gypsum production line. The dihydrate gypsum production line includes a reaction chamber, a pH adjustment tank, a sedimentation tank and a waste liquid tank. The sedimentation tank includes a lifting and filtering device, a drainage system, a flushing Device, sedimentation monitoring system and control system, the product lifting filtration and waste liquid removal system of the dihydrate gypsum production line of the present invention are timed sedimentation and automatic filtration of products, which can not only improve filtration efficiency and reduce drying costs, but also further reduce transportation costs And improve transportation efficiency, and the waste liquid removal system discharges the waste liquid from the dihydrate gypsum production line to the waste liquid pool for subsequent treatment. Compared with the traditional dihydrate gypsum preparation process, the dihydrate gypsum preparation process of the present invention improves the efficiency of dry extraction of dihydrate gypsum precipitated products, realizes and collects the waste liquid removal system into the waste liquid pool, providing better treatment for the subsequent treatment process Provide a certain guarantee, and also save the operating cost of subsequent waste liquid treatment.

Description

technical field [0001] The invention relates to the field of preparing dihydrate gypsum, in particular to an automatic lifting and filtering product system for a dihydrate gypsum production line Background technique [0002] Dihydrate gypsum can be used as one of the important raw materials for gypsum products such as gypsum blocks and slabs, land improvers, road construction materials, cement industry retarders and ordinary β-type gypsum powder. Due to the large demand for dihydrate gypsum , the production and utilization of calcium sulfate dihydrate, that is, dihydrate gypsum, is becoming more and more extensive. At present, the extraction process of dihydrate gypsum generally adopts the traditional extraction process. According to the reaction between sulfuric acid solution and calcium-containing ore powder, dihydrate gypsum is obtained by precipitation Precipitation product. [0003] Relying on the research team of the chemical laboratory of the university and the resou...

Problems solved by technology

In the traditional production process, the reaction mixture in the sedimentation tank is transported to the filter room for filtration after sedimentation. During the transportation process, the loss of the dihydrate gypsum precipitation product and the discharge of the waste liquid will be caused, and the filter room occupies the operating area. Most of the site area and energy consumption

[0004] In order to solve the common problems in the field of the traditional dihydrate gypsum production and preparation process, the loss of sediment transfer and transportation, the difficulty of centralized recovery of waste liquid, the energy consumption of the filter room and the inconvenient washing of dihydrate gypsum precipitation products The research team made the invention
