Bentonite slurry self-circulation system

Abstract

The invention provides a bentonite slurry self-circulation system, and belongs to the field of material mixing equipment. The bentonite slurry self-circulation system comprises at least three materialstorage boxes, a material pump is arranged between two adjacent material storage boxes, and two ports of the material pump are respectively communicated with the two material storage boxes; each of the material storage boxes comprises a box body, a pneumatic material mixing device installed on the box body and two material pipes communicated with the box body; and each pneumatic mixing device comprises air injection mechanisms symmetrically installed on the two sides of the box body, and each air injection mechanism comprises an air supply pipe fixedly installed on the box body and a plurality of air injection channels obliquely penetrating through the side wall of the box body from top to bottom. According to the bentonite slurry self-circulation system provided by the invention, slurrycan be circularly stirred, the situation that new slurry and old slurry are mixed to change the viscosity of a product is effectively avoided, stirring can be directly conducted in the box body, slurry movement can be kept during storage, slurry precipitation is avoided, and the quality of the slurry can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mixing equipment, and in particular relates to a bentonite slurry self-circulation system. Background technique [0002] In order to ensure the stability and engineering quality of the groove wall of the underground diaphragm wall during the construction process, the mud retaining wall technology has been widely used and promoted. Based on the analysis of factors affecting the stability of the underground diaphragm wall groove wall, the application of mud retaining walls is very important. With the development of underground space, underground diaphragm walls are widely used, and the stability of the groove wall by the groove forming mud in the construction of underground diaphragm walls is very important. It is one of the most fundamental measures to use mud to ensure the stability of the underground diaphragm wall in terms of performance, sediment cleaning, groundwater leakage and construction costs.

Problems solved by technology

At present, in the pulping storage devices on the market, after the pulp is mixed, it is directly stored inside the old pulp. However, the mixing of new pulp and old pulp will cause the viscosity of the pulp to change, which will affect the reliability of the pulp; and the pulp If the material is left standing for a long time, it will easily lead to the precipitation of the slurry, which will affect the quality of the slurry
