Slurry mixing machine

Abstract

The invention provides a slurry mixing machine comprises a cylinder body and a rotor located in the cylinder body, the cylinder body (1) is provided with a screen area, the inner wall of the cylinderbody is provided with a plurality of protruding fixed teeth which are arranged in multiple rows at intervals, and a vacant section is arranged between every two adjacent rows of protruding fixed teeth; wherein the rotor is formed by superposing a plurality of rotating sheets, each rotating sheet comprises at least two blades, a part between every two adjacent blades is cut off to form a notch, andconvex rotating teeth are arranged on the outer side of each blade; and each rotating sheet deflects for one deflection angle around the shaft in sequence relative to one rotating sheet on the rotating sheet, so that each rotating sheet forms an offset step surface in each vacant groove relative to the adjacent rotating sheet, and forms a space required by falling of materials like a spiral stairin the vacant grooves. The mixing machine is suitable for mixing viscous materials with self-closing internal molecular structures, such as high-viscosity syrup materials, grease materials and chemical materials; the mixing machine is especially suitable for preparing sludge coal water slurry, and can thoroughly break the net-shaped structure of a sludge flocculating agent to fully separate out water in the sludge flocculating agent.

AI Technical Summary

Problems solved by technology

At present, the main difficulty in preparing coal-water slurry from sludge is that the sludge treated by flocculants has a high viscosity, and the network structure of flocculants makes it difficult to fully mix with coal-water slurry, which greatly increases the viscosity of the slurry

The sludge contains a large amount of internal water, which not only reduces the concentration and calorific value of the sludge coal water slurry, but also prevents the combustion of organic matter in the sludge, so that the coal water slurry prepared from the sludge cannot be fully burned, and the coal water slurry consumes the sludge The proportion of the sludge is greatly limited, and the best effect of sludge energy utilization cannot be achieved.

In the currently commonly used ball mill pulping system, the sludge and granular coal are generally added to the ball mill to grind and mix the pulp. The ball mill usually cannot destroy the flocculation network structure of the sludge, nor can it use the sludge in the sludge. Internal water, most of which is cell water, the sludge will agglomerate by itself into large and small agglomerates with high internal moisture content, which will cause uneven mixing and fail to achieve good combustion performance as slurry fuel
