Blocky sludge drying system

Abstract

A blocky sludge drying system comprises a material receiving device, a conveying platform, a tray, a three-dimensional transfer device, a drying frame and a discharging box, the material receiving device comprises a material receiving frame, a material conveying crawler belt and a blade roller; and a discharging opening is formed in front of the bottom of the collecting frame, and a pushing assembly is arranged in the collecting frame. The material receiving device and the conveying platform are connected, the sludge is transferred into the drying frame and the discharging box through the three-dimensional transferring device, the blade roller is arranged outside the discharging port of the material receiving frame, the plate-shaped sludge is cut into strip-shaped sludge through the blade roller, the specific surface area of the sludge is effectively increased, and therefore the later dehydration energy consumption is reduced; meanwhile, due to the design of the quasi-closed discharging box, the secondary pollution of raised dust generated in the bagging process of the dried sludge is reduced to the greatest extent; and transportation is performed through the three-dimensional transfer device, so that the greenization and automation degree of the sludge drying working environment is remarkably improved.

Description

technical field [0001] The invention relates to a sludge drying system, in particular to a bulk sludge drying system. Background technique [0002] Sewage treatment is an important environmental protection facility. With the improvement of environmental requirements, the degree of sewage treatment is getting higher and higher, and more and more sludge is produced, and the scale of sludge treatment is also increasing. Sludge treatment is the most complex and costly part of the wastewater treatment system. [0003] Sludge incineration is the most thorough treatment method for sludge. It can completely carbonize organic matter, kill pathogens, minimize the volume of sludge and realize energy recovery and utilization, and solve the final disposal problem of sludge solid waste. [0004] Before incineration, sludge needs to undergo a series of procedures such as concentration, dehydration, and drying, so as to reduce the water content of sludge and save energy consumption in the...

AI Technical Summary

Problems solved by technology

[0007] However, the commonly used heat pump box-type drying equipment now requires manual loading and unloading, and the workload is heavy. The sludge handling process is prone to produce harmful substances (heavy metals)

microorganisms) dust, which pollutes the working environment and also poses potential hazards to the health of workers

[0008] Therefore, the existing sludge drying system using heat pump box-type drying equipment has the problems of heavy manual work, heavy dust pollution and serious environmental pollution and harm to workers' health.
