Sludge slurrying machine

Abstract

The invention provides a sludge slurrying machine. The sludge slurrying machine comprises a transmission device, a transmission shaft, paddles, a casing and a base, wherein the transmission device and the casing are mounted on the base; the transmission device is connected with the transmission shaft and used for driving the transmission shaft to rotate; one end of the transmission shaft is connected with the transmission device, and the other end extends into the casing and is provided with the paddles; the paddles and the transmission shaft are set to form angles and are used for stirring and conveying sludge; a sludge addition port is formed in the upper end of the casing and used for addition of dewatered sludge to the casing; a discharging end is arranged at the bottom end of the casing and used for outputting a mixed and slurried material out of the sludge slurrying machine; the base is connected with the casing and used for supporting the sludge slurrying machine.

Description

technical field [0001] The invention relates to the field of municipal sludge treatment, and more specifically relates to a sludge pulping machine. Background technique [0002] Affected by the national environmental protection policy, the requirements for the treatment and disposal of sludge in municipal sewage treatment plants are becoming increasingly stringent. Anaerobic digestion is a treatment technology that can achieve sludge reduction, stabilization, harmlessness, and resource utilization. It is suitable for large-scale Promote projects that are large in size, have high sludge organic matter content, or require centralized treatment and disposal. [0003] When the sludge treatment and disposal plant conducts anaerobic digestion project construction, the moisture content of the sludge received from the external factory is generally about 80%, which cannot be directly anaerobic digestion, and water or thin sludge (with a moisture content of 97%-99% ) to dilute, adjus...

AI Technical Summary

Problems solved by technology

[0006] (1) Due to the complex nature of the sludge, it will contain some fibrous impurities, which are entangled on the shaft and blades of the vertical axis agitator, and the accumulation of time will cause the decline of the stirring effect and affect the normal use

[0007] (2) When bricks, small stones, iron blocks and other hard debris enter, it is very easy to damage the blade, and the replacement and maintenance procedures of the blade are more complicated

Since the dewatered sludge has basically no fluidity, it is difficult to clean and empty;

[0009] (4) Affected by the structure of the vertical mixing tank, sludge and diluent are added from the top and flow out from the bottom, which is suitable for sequential batch production. When continuous production is carried out, it is difficult to control the amount of material and the effect of pulping

The sequential batch production increases the number of equipment and the difficulty of control, requiring frequent switching of equipment

[0010] Based on the shortcomings of the above-mentioned existing technologies, it is necessary to develop a new type of sludge slurry equipment that can solve the problems of equipment winding, blockage, difficult emptying and operation control
