Device for preparing ceramsite cat litter from urban sludge

The invention discloses a device for preparing ceramsite cat litter from urban sludge. The device structurally comprises a sludge putting hopper, a control displayer and the like. In order to overcome the defects of the prior art and solve the problems that a large amount of urban sludge is accumulated, solid waste in the sludge is likely to cause secondary pollution under the action of microbial degradation, coal cinder and ceramsite cannot be fully mixed in a production process, and the preparation quality is low, the device for preparing the ceramsite cat litter from urban sludge has the advantages that the sludge putting hopper, a sludge waste separation mechanism, a screening purification mechanism and a deep mortar and pestle mechanism are designed, accumulation of sludge is reduced, a reasonable outlet is found for the sludge, solid waste and soft biological humus are separated from the sludge to ensure that soft matter cannot be scattered or mixed with the sludge during natural filtration, waste mater
