Batching device for preparing high-strength gypsum a from industrial byproduct gypsum

Abstract

The invention discloses a batching device for preparing high-strength gypsum a from industrial byproduct gypsum. The device comprises a stirring barrel, a pulverizer, an exhaust fan and a liquid containing barrel. The top end of the stirring barrel is connected with the pulverizer through a communication mechanism, and the top end of the stirring barrel is connected with a stirring mechanism and an air pressurizer. The top end of the stirring barrel is connected with a transverse plate through multiple sets of countersunk bolts, a water liquid barrel and a reaction liquid barrel are arranged at the top end of the transverse plate, the exhaust fan is connected to the top ends of the water liquid barrel and the reaction liquid barrel, the two sides of the exhaust fan communicate with ventilation hoppers, the ventilation hopper on one side communicates with two sets of water passing pipes through a multi-way valve, the two sets of water passing pipes are connected to the inner walls of the water liquid barrel and the reaction liquid barrel through two sets of fixing clamps correspondingly, the ventilation hopper on the other side communicates with two sets of air suction pipes through a multi-way valve, and the two sets of air suction pipes communicate with the stirring barrel and the pulverizer correspondingly. The batching device for preparing the high-strength gypsum a from the industrial byproduct gypsum not only can treat powdery gypsum and blocky gypsum, but also can assist in improving the discharging speed.

Description

technical field [0001] The invention belongs to the technical field of gypsum processing and batching, and in particular relates to a high-strength gypsum batching device for preparing a high-strength gypsum from industrial by-product gypsum. Background technique [0002] Gypsum is a monoclinic mineral, a hydrate whose main chemical composition is calcium sulfate (CaSO4). Gypsum is a versatile industrial and construction material. It can be used in cement retarder, gypsum building products, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. The microporous structure and heating dehydration of gypsum and its products make it have excellent sound insulation, heat insulation and fireproof performance. [0003] Industrial by-product gypsum is used to prepare a high-strength gypsum by adding a crystal-transforming agent and undergoing an autoclaved crystal-transforming process. Before autoclaving, it is necessary to carry out batchin...

Problems solved by technology

The advantage is that it can stir and process the sulfide gas produced, but its disadvantage is that before stirring, some powdery gypsum is processed when it is circulated with the air, resulting in waste of resources, and it is not convenient to process the stirred gypsum. Discharge

Moreover, the industrial by-product gypsum usually contains moisture or even wet sticky gypsum, and the ordinary gypsum mixing device is difficult to adapt to, and there will be a phenomenon of poor feeding and uneven mixing, which cannot meet the batching requirements of industrial by-product gypsum to prepare a high-strength gypsum
