Crushing assembly used for sludge crushing device and construction method of crushing assembly

Abstract

The invention provides a crushing assembly used for a vertical sludge crushing device. The crushing assembly is arranged in a vertical shell body and includes a rotatable assembly and a fixing assembly and ring pieces. The rotatable assembly includes a rotation shaft and a rotation arm extending outwards vertically from the lower end of the rotation shaft. The rotation arm is provided with crushing assemblies arranged at intervals and expanding parallel to the rotation arm in the length direction of the rotation arm. The fixing assembly includes a fixing supporting seat. The fixing supportingseat is provided with a central column and supporting rods vertically extending outwards from the central column. One end of each supporting rod is fixed to the central column. The ring pieces can bearranged on the supporting rods at certain intervals around the central column and in the length direction of the supporting rods. The rotatable assembly and the fixing assembly are arranged up and down, and the crushing assemblies on the rotation arm are in staggered arrangement relative to the ring pieces on the supporting rods. Each crushing assembly is corresponding to the corresponding spacebetween the two adjacent ring pieces and can extend into the space. The invention further relates to a method of constitution of the crushing assembly used for the vertical sludge crushing device.

Description

technical field [0001] The present invention relates to the field of sludge drying, and relates to a crushing assembly for a sludge crusher, especially a crushing assembly for crushing sludge blocks in a vertical sludge crusher and the method for constructing the crushing assembly method. Background technique [0002] The sludge drying process usually requires dehydration of liquid sludge to treat the liquid sludge into solid sludge. Dehydration treatment generally uses solid-liquid separation equipment to separate solid-liquid from the sludge, and the dehydrated sludge forms a larger block with a certain water content. In order to facilitate subsequent landfilling, solidification or Drying also requires breaking larger sludge blocks into smaller ones. Compared with other solid-liquid separation equipment, the sludge block with high solid content can be obtained by using the filter press, and its water content is about 75%~40%, and the sludge block has the characteristics ...

AI Technical Summary

Problems solved by technology

However, there are many deficiencies in these crushing equipment, one of which is that the equipment is prone to be blocked by sludge blocks during the sludge crushing process, and the size of the crushed small blocks is not uniform, which makes the operation of the equipment difficult. Poor sustainability and affects the stability of sludge crushing, thus increasing the difficulty of subsequent treatment, especially in the drying process it is difficult to further reduce the moisture content of the crushed sludge small pieces

For this reason, a kind of vertical sludge crusher proposed by the applicant that the crushing process is stable and can obtain sludge fragments of uniform particle size can alleviate or avoid these problems, however, there is a defect in this vertical crusher For sludge blocks with different moisture content, only one type of crushing component can be used for crushing or shearing. Therefore, it is necessary to propose a crushing component based on different moisture content and adapting to different environmental conditions and the structure of the crushing component. method
