Sludge mixing granulation device and method

Abstract

The invention relates to the technical field of granulation devices, and concretely relates to a sludge mixing granulation device and method. The sludge mixing granulation device comprises a granulation device body, a purification device and a water tank, the granulation device body is of a cylindrical hollow structure, a mixing and stirring device is arranged on the upper portion of the granulation device body, and a feeding pipe is arranged on the side edge of the top of the mixing and stirring device; a motor is fixedly welded to the top of the mixing and stirring device, a stirring rod is welded to the output end of the motor, a granulating device is arranged on the lower portion of the granulating device body, a baffle is arranged between the granulating device and the mixing and stirring device, a bearing is arranged on the lower portion of the baffle, the baffle is rotationally connected with a rotating plate through the bearing, and a telescopic rod and a contraction rod are arranged at the top of the rotating plate; and an air heating device is arranged on the upper portion of the granulation device body, and the purification device is arranged on the side edge of the granulation device body. Sludge is stirred through the mixing and stirring plate device and then granulated, sludge odor is purified through the purification device, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of granulation devices, in particular to a sludge mixing and granulation device and a granulation method. Background technique [0002] Sludge is the product of sewage treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content, high organic matter content, and easy It is rotten and smelly, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. It is a thick substance between liquid and solid. It can be transported by pump, but it is difficult to separate solid and liquid by sedimentation. [0003] Sludge can be used to make ceramsite, but the existing sludge mixing and granulation device does not have the function of purifying odor, polluting the environment, and the existing sludge mixing and granulation device has complicated ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sludge mixing and granulation device and a granulation method to solve the problem that the existing sludge mixing and granulation device proposed in the above background technology has no function of purifying odor, pollutes the environment, and the existing sewage The mud mixing and granulating device has complex procedures, long transportation time, and no problem of preheating the sludge granules in advance
