Granulating machine for sludge drying

Abstract

The invention discloses a granulating machine for sludge drying. The granulating machine comprises a machine body, wherein the machine body comprises a material charge device and a granulating device;the material charge device comprises a buffer material bin; the front side of the upper part of the buffer material bin is provided with two material charge pipe orifices; the granulating device comprises a casing and a granulating roll, a rotary joint is arranged at one side of the granulating roll, a gear is arranged at the other side of the granulating roll, a chain wheel is arranged at the other side of the gear, a bearing block is arranged at one side, near the rotary joint, of the granulating roll, a material cleaner is arranged under the bearing block, a material receiving plate is arranged under the granulating roll, a decelerator and a motor are arranged under one side of the granulating device, a condensate outlet is formed in one side, away from the decelerator, of the lower part of the front side of the granulating device, the upper part of the back side of the granulating device is provided with a waste air outlet, and one side, near the condensate outlet, of the lower part of the back side of the granulating device is provided with a steam inlet. Compared with the prior art, the granulating machine has the advantages that by adopting multiple heating types for simultaneously heating, sludge can be quickly dried; by adopting multiple granulating manners, the granulating is finer; the structure is simple, and the cleaning is convenient.

Description

technical field [0001] The invention relates to the field of sludge drying, in particular to a granulator for sludge drying. Background technique [0002] Municipal sludge is treated by sludge drying. Sludge has a high viscosity. When sludge is granulated, it is easy to stick to the inner wall of the barrel of the granulator. In the prior art, it is used for sludge drying. The advanced granulator, single granulation, granulation is not fine enough, the heating or drying method of sludge is very single, so that the sludge cannot be dried quickly, the cleaning ability is poor, and it is not easy to cool after heating. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a granulator for sludge drying that can be cooled rapidly and cleaned up in time. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A granulator for slud...
