Problems solved by technology

[0003] The sludge drying equipment in the prior art is shown in the People's Republic of China Invention Patent No. 201020214114.3, which is equipped with at least two spindle systems, so that the sludge drying equipment Large area, complex structure, troublesome operation and maintenance
At the same time, the spindle system is provided with a helical paddle, and the sludge is driven by the rotation of the helical paddle. However, the helical paddle cannot fully stir the sludge, and the sludge is heated unevenly. , the drying efficiency of the equipment is low, and the sludge is easily bonded to the inner wall and requires manual cleaning, which is time-consuming and laborious
[0004]At the same time, because the sludge needs a certain period of heat preservation during the drying process, the existing drying equipment usually does not have the above functions

Embodiment Construction

[0034] Please refer to the attached figure 1 To attach Figure 10 As shown, the present invention is a disc type sludge dryer, which consists of a housing 1, a spindle system 2, a gear motor 3, a transmission end bearing device 4, a steam end bearing device 5, a heating and heat preservation device 6 and a discharge device 7 and other systems.

[0035] Wherein, the main shaft system 2 and the heating and heat preservation device 6 are accommodated in the housing 1, the main shaft system 2 is used to stir and heat the sludge to make it preliminarily dry, and the heating and heat preservation device 6 is used for heat preservation of the preliminarily dried sludge, Let it dry out further. The transmission end bearing device 4 and the steam end bearing device 5 are respectively installed at both ends of the main shaft system 2. The transmission end bearing device 4 is used to transmit power to the main shaft system 2 to make the main shaft system 2 rotate. The steam end bearin...

Abstract

The invention relates to a disc type sludge dryer which comprises a shell body, a main shaft system, a speed reduction motor, a transmission end bearing device, a steam end bearing device, a heating and heat insulation device and a discharge device, wherein the main shaft system and the heating and heat insulation device are contained in the shell body; the transmission end bearing device and thesteam end bearing device are respectively installed at the two ends of the main shaft system; the speed reduction motor is connected with the main shaft system through a coupling and drives the main shaft system to rotate; and the discharge device is installed at one side of the shell body adjacent to the steam end bearing device. The disc type sludge dryer has the advantages that the disc type sludge dryer is simple in structure, has small floor area and good heating and heat insulation performance, completely agitates and dries, saves energy sources and the like.

Description

technical field [0001] The invention relates to sludge drying equipment, in particular to a disc-type sludge drying machine, which belongs to the technical field of environmental protection equipment. Background technique [0002] Sludge is a kind of solid sediment produced in the process of water and sewage treatment. The main source is municipal sewage, industrial sewage, water dredging and other sewage treatment processes. Its output is large and has great harm to human body and environment. . Sludge has a high water content (up to 90% or more), high organic matter content, easy to rot and smell, and the particles are finer, the specific gravity is smaller, and it is in a colloidal liquid state. At present, the main disposal methods of sludge are landfill, incineration and drying treatment. However, the landfill and incineration of sludge are likely to cause secondary pollution. Therefore, the use of sludge drying equipment to dry sludge is widely used. [0003] The sl...
