Problems solved by technology

When the sludge is recycled, it is necessary to crush and screen the sludge to provide sludge with a relatively uniform fineness. However, there is no device in the prior art that can crush and screen the sludge at the same time. Sludge treatment equipment is to crush the sludge first, and then sieve the sludge after the crushing treatment. The operation is more troublesome, the process is longer, and it consumes more time and energy.

Abstract

The invention relates to the field of municipal sludge treatment, in particular to a crushing and screening device for municipal sludge treatment. The crushing and screening device comprises a sludgecrushing barrel assembly, a drive control assembly, a transmission wheel assembly, a sludge extruding and screening box assembly, a sludge screening and dropping box, a sludge return box assembly anda supporting base, wherein the lower end of the sludge crushing barrel assembly is connected with and communicated with the sludge extruding and screening box assembly; the lower end of the sludge extruding and screening box assembly is connected with and communicated with the sludge screening and dropping box; the sludge return box assembly is fixedly connected to the outer side surface of the sludge screening and dropping box; and the sludge return box assembly is arranged at the lower end of the sludge extruding and screening box assembly. The crushing and screening device integrates crushing and screening of sludge, is internally equipped with the sludge crushing barrel assembly and the sludge extruding and screening box assembly, and can synchronously crush and screen sludge; and moreover, the sludge crushing barrel assembly and the sludge extruding and screening box assembly adopt the same drive control assembly to drive, so that matching is tight, and therefore, the sludge treatment efficiency and the sludge treatment effect can be effectively improved, and energy saving and consumption reducing are achieved.

Description

technical field [0001] The invention relates to the field of municipal sludge treatment, in particular to a screen breaking device for municipal sludge treatment. Background technique [0002] Sewage biochemical treatment is accompanied by sludge. Improper treatment and disposal of sludge may cause great harm to the environment and human and animal health. Municipal sludge contains about 70% organic matter, resulting in high COD, BOD and ammonia nitrogen. Usually, composting, anaerobic / aerobic, incineration and other methods are used to oxidize and degrade the above organic matter. However, the organic matter content in sludge in my country is relatively low. Low, foreign organic matter content is 60-70%, China's organic matter content is 30-50%, resulting in low calorific value, difficult to support combustion; low gas production rate, low anaerobic digestion efficiency and other problems. Sludge is not only an environmental waste, but also a resource that can be used. Whe...
