Smashing drying output device for papermaking plant sludge

Abstract

The invention discloses a smashing drying output device for papermaking plant sludge and belongs to the field of environment-friendly equipment. The smashing drying output device comprises a box, wherein support legs are arranged at the bottom of the box; the support legs are fixedly connected with the box; a smashing chamber and a drying chamber are arranged in the box; a feeding hopper is arranged on a central line of the top end of the box; a plurality of first smashing blades are uniformly arranged on left and right sides of a first smashing shaft; a second turning wheel is arranged at the left end of the box through a bracket; the bracket is fixedly connected with the box; a driving motor is fixedly arranged at the right end of the box; a first turning wheel is arranged on the driving motor; the first turning wheel is connected with the second turning wheel through a conveying belt; the conveying belt is horizontally arranged in the drying chamber. The smashing drying output device is reasonable in structure design; a smashing device is arranged for thoroughly smashing the solid particles in the sludge, so that the drying efficiency can be increased; a drying device is arranged for quickly drying the sludge.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a paper mill sludge crushing and drying output device. Background technique [0002] Except for some of the sludge from paper mills that has been comprehensively utilized, the rest are disposed of in sanitary landfills, requiring more than 700,000 mu of land to be landfilled every year, which not only wastes land resources, but also produces secondary pollution; papermaking sludge is a biological solid waste. It contains a large amount of cellulose organic matter and plant nutrients such as nitrogen, phosphorus, and potassium. According to this characteristic, papermaking sludge can be turned into agricultural fertilizer; the traditional method is to stack the sludge in the sedimentation tank and air-dry it directly as soil improvement. However, the existing method takes a long time and cannot crush the larger solids in the sludge, which is time-consuming and lab...

[0002] Except for some of the sludge from paper mills that has been comprehensively utilized, the rest are disposed of in sanitary landfills, requiring more than 700,000 mu of land to be landfilled every year, which not only wastes land resources, but also produces secondary pollution; papermaking sludge is a biological solid waste. It contains a large amount of cellulose organic matter and plant nutrients such as nitrogen, phosphorus, and potassium. According to this characteristic, papermaking sludge can be turned into agricultural fertilizer; the traditional method is to stack the sludge in the sedimentation tank and air-dry it directly as soil improvement. However, the existing method takes a long time and cannot crush the larger solids in the sludge, which is time-consuming and labor-intensive; therefore, we need a paper mill sludge crushing and drying method. output device
