A sludge dryer

Abstract

The invention discloses a sludge dryer, comprising a front support, a rear support, a drum installed between the front support and the rear support, a first driving mechanism for driving the drum to rotate, a copying plate assembly and The second drive mechanism; the copy board assembly includes a first connector, a second connector, and several copy boards connected between the first connector and the second connector, and the copy board assembly is movably adapted in the drum; copy The board assembly has a first state and a second state. When the copy board assembly is in the first state, the first connector and the second connector are locked at the front and rear ends of the drum. When the copy board assembly is in the second state, the A connecting piece is locked on the front support, and the second connecting piece is locked on the rear support; the second driving mechanism is used for driving the copy board assembly to switch between the first state and the second state. The invention can clean up the sludge adhering to the inner wall of the drum under the condition of non-stop operation, without manual cleaning and without interrupting the operation of the equipment, thereby ensuring the continuity of the drying operation.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge dryer. Background technique [0002] Sludge is the solid sedimentary material produced by water and sewage treatment processes. With the strengthening of national energy conservation and emission reduction, the improvement of national environmental protection awareness, and the increasing production of urban sludge, sludge disposal and development and utilization have become an important issue in the national environmental protection work. The development of sludge drying treatment technology makes it possible to use sludge for agriculture, sludge fuel and sludge incineration. The improvement and innovation of sludge drying technology and sludge dryer have directly promoted the development of sludge disposal methods, expanded the selection range of sludge disposal methods, and made them obtainable in terms of safety, reliability and sustainability.

Problems solved by technology

[0004] However, when the drum type sludge dryer is working, the sludge is easy to adhere to the inner wall of the drum. If the sludge adhered to the inner wall of the drum is too thick, it will affect the lifting board to throw the sludge, thus affecting the drying effect. , it is necessary to regularly clean the sludge on the inner wall of the drum

At present, most of the drum type sludge dryers need to manually enter the inside of the drum to clean the sludge on the inner wall of the drum. The labor intensity of the workers is relatively high, and the cleaning efficiency is low, which greatly delays the work.
