Production device and production method for preparing polyaluminum chloride from environment-friendly aluminum slag

Abstract

The invention relates to the field of polyaluminum chloride production, in particular to an environment-friendly production device for preparing polyaluminum chloride from aluminum slag, which comprises a tank body, the top of the tank body is fixedly connected with a motor, and the rotating end of the motor penetrates through the tank body and is fixedly connected with a stirring rod. The environment-friendly production device for preparing the polyaluminum chloride from the aluminum slag is composed of a transmission mechanism, a smashing mechanism and a conveying mechanism, a transmission rod reciprocates on a reciprocating lead screw along with a supporting plate, and when the transmission rod and a sealing gasket move in a matched mode, an aluminum slag mixed solution in a tank body is extracted; the aluminum slag is crushed in the rotary stirring process of the main stirring blades and the auxiliary stirring blades, so that the chemical reaction effect of the aluminum slag and a reaction solution is rapidly improved; in the process that the transmission rod drives the aluminum slag mixed liquid to be pushed to the lower portion of the collecting sleeve through the sealing gasket, the smashed aluminum slag mixed liquid is sprayed out of the second one-way valve, aluminum slag accumulated at the bottom of the tank body is pushed upwards, and the situation that due to aluminum slag accumulation, part of aluminum slag cannot react completely is avoided.

Description

technical field [0001] The invention relates to the field of polyaluminum chloride production, in particular to a production device and a production method for preparing polyaluminum chloride from an environment-friendly aluminum slag. Background technique [0002] Polyaluminum chloride is an inorganic emerging water purification material. It has good stability, wide adaptability to water, fast hydrolysis and strong adsorption capacity. It is widely used in drinking water, industrial water and sewage treatment. Polychloride is prepared from aluminum slag In the process of aluminum melting, it needs to be prepared by chemical reaction of aluminum slag and reaction solution. [0003] In the production process of preparing polyaluminum chloride from some existing aluminum slag, the particles of some aluminum slag are relatively large, and it is difficult to quickly chemically react with the reaction solution, which affects the production efficiency; in the production process of...
