Device for producing liquid cement grinding aid

Abstract

The invention relates to a device for producing a liquid cement grinding aid. The device comprises a frame and a tank fixed to the frame. The top of the tank is provided with a feeding inlet. The upper part of the tank is cylindrical, the lower part of the tank is in a shape of a tapered drum, the lower end of the tapered drum is provided with a discharge outlet, a rotation shaft is vertically arranged in the tank, the upper end of the rotation shaft is rotatingly supported in a support beat and is connected to a motor through a belt driving mechanism, the lower end of the rotation shaft is rotatingly supported by a support in the tank, the support comprises support legs and a bearing pedestal fixed to the support legs, each one of the support legs is provided with a bar-type hole allowing a liquid cement grinding aid to go through, the lower end of the rotation shaft is rotatingly supported in the bearing pedestal, the side wall of the rotation shaft is provided with several stirring blades, long edges of the stirring blades extend along a horizontal direction, wide edges of the stirring blades extend inclinedly and form an inclined angle alpha with the horizontal plane. The device can effectively mix various materials and the tank has no stirring blind angle so that product quality is improved.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a production device for producing liquid cement grinding aids. Background technique [0002] At present, our country is in the climax of large-scale capital construction. According to statistics, the annual output of cement in the country is more than 2 billion tons, and the output of concrete is more than 2 billion cubic meters, 40% of which are mixed with various additives. Rapid development. By the end of 2009, China's highway construction has reached 60,300 kilometers, and the mileage of rural roads has reached 3.24 million kilometers. Due to the needs of these development situations, the research and development of high-performance cement and concrete additives is imminent. [0003] Since the thirties in the 20th century, Englishman Goddard has obtained a patent with resin as a grinding aid. People have tested grinding aids such as acetic acid, phosphate, lignosulfonate, et...

AI Technical Summary

Problems solved by technology

[0004] Existing problems: At present, there are many companies producing liquid cement grinding aids in the market. When producing liquid cement grinding aids, most of them use compounding technology, which requires the use of multiple solid and liquid raw materials. During the process of mixing and dissolving with water, Due to the design defect of the mixing pot itself, the mixing raw materials are uneven, the product quality is not good, and there is a dead angle in the mixing
