Problems solved by technology
[0004] The purpose of the present invention is to provide a low-temperature sludge drying system for the problem that the sludge (water content less than 65%) in the sludge deep removal system cannot enter the sludge drying system because it cannot be extruded and formed. The material distribution system and material distribution method enable the sludge from the sludge deep removal system in sludge treatment to directly enter the sludge low temperature drying treatment system

Abstract
The invention discloses a sludge low-temperature drying distributing system and a distributing method. The distributing system comprises a sludge cake crusher, a sludge bin, a sludge grain blanking screw and a sludge spreader. The sludge cake crusher is connected with the sludge bin of a filter press. Sludge cake crushing tooth rollers are arranged on the sludge cake crusher. The sludge bin is arranged below the sludge cake crushing tooth rollers of the sludge crusher. A sludge bin vibration motor is arranged on the sludge bin. The sludge grain blanking screw is arranged at the bottom of the sludge bin. A plurality of blanking openings formed discontinuously are formed in a sludge outlet in the bottom of the sludge bin. Weighing equipment is arranged at the bottom of the sludge bin. The sludge outlet of the sludge bin is formed above a drying crawler belt of a sludge low-temperature drying system. The sludge spreader is arranged above the drying crawler belt and behind the sludge bin.A sludge guide row plate is arranged at the lower end of the sludge spreader. A sludge spreader vibration motor and a sludge spreader lifting motor are arranged on the sludge spreader. The distributing system and the distributing method can lead the sludge cake from a sludge deep water removal system to directly enter the sludge low-temperature drying system for drying treatment.
Description
technical field [0001] The invention belongs to the technical field of sludge treatment and disposal, and relates to a low-temperature drying sludge distribution system and a distribution method. Background technique [0002] The sludge from the urban domestic sewage treatment plant is concentrated by the sludge thickener (stacked screw sludge thickener, etc.), and then dehydrated by the filter press (ultra-high pressure elastic press, etc.) The moisture content of the mud cake can be controlled below 60%, and then it will be landfilled or incinerated. With the development of the sludge drying industry, the sludge drying technology and drying equipment are becoming more and more mature, and the sludge removal system filter press for drying has become the mainstream trend of sludge treatment. Among the many sludge drying technologies, low-temperature sludge drying technology has a good market prospect due to its advantages of environmental protection and energy saving. [0...
