Sludge crushing machine

Abstract

The invention relates to a sludge crushing forming machine which comprises a sludge feed bin, wherein a pair of sludge crushing rollers and a pair of sludge bar pressing forming rollers are arranged in the sludge feed bin from top to bottom; the two sludge crushing rollers are parallel to each other and sludge crushing branch forks which are mutually staggered are formed on the surfaces; engaged gears are installed at the same ends of the two sludge crushing rollers, the gears are driven by a variable frequency motor, the two sludge bar pressing forming rollers are parallel to each and are engaged to each other, engaged gears are further installed at the same ends of the two sludge bar pressing forming rollers, and the gears are driven by the variable frequency motor. The sludge crushing forming machine provided by the invention can quickly and efficiently prepare urban domestic sludge raw materials which are high in water content and have difficulty in forming relative stable shapes into stripe sludge in batches so as to increase the contact area between sludge and hot air flows in a subsequent drying treatment step and reduce the flow resistance of the hot air flows penetrating through sludge, so that the drying efficiency is effectively improved, and meanwhile, the dried sludge is stripe particles, thereby greatly reducing dust generated in the following transportation and storage processes.

Description

technical field [0001] The invention relates to sludge treatment equipment, in particular to a sludge crushing and forming machine. During the entire physical drying treatment process of sludge, the sludge crushing machine is used to pre-form the sludge raw material to ensure the efficiency and high quality of the subsequent drying treatment process. Background technique [0002] With the development of urban construction and the improvement of living standards, the generation of urban domestic sludge is also increasing, and the long-term accumulation will greatly affect the urban environment and air quality. At present, the methods of batch treatment of municipal domestic sludge are generally physical methods and biochemical methods. The physical method is generally drying treatment, that is, removing most of the water contained in the sludge, and then performing harmless treatment on the remaining slag. be processed or diverted to other uses. Compared with biochemical tr...
