Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant stacking sheets, and more specifically to a wear-resistant stacking sheet of a spiral stacking type sludge dewatering machine. Background Art

[0002] The working principle of the spiral stack sludge dewatering machine is a filtering push device formed by stacked plates running through it. The front end is the concentration part and the rear end is the dewatering part. The spiral shaft drives the stacked plates to rotate and pushes the sludge from the concentration part to the dewatering part. In the process of moving forward, the distance between the filter seam and the stacked plates gradually decreases, thereby achieving the purpose of full dehydration.

[0003] The existing spiral stack sludge dewatering machine has stacked plates directly fixed on the rotating shaft. Once maintenance or replacement is required, the entire rotating shaft or part of the structure may need to be removed, which increases the difficulty and cost of maintenance. In addition, the stacked plates are mainly made of stainless steel metal materials such as 304. Metal materials such as 304 have poor wear resistance and corrosion resistance, which limits the service life of the spiral stack sludge dewatering machine. In addition, the existing spiral stack sludge dewatering machine has low transmission efficiency and poor load-bearing capacity and cannot meet user needs. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model sequentially places the first fixing block, the circular stack and the second fixing block onto the rotating shaft, at which time the first limiting block and the second limiting block are connected to the second mounting groove on the circular stack, and then uses the second bolt and the fixing nut to fix the circular stack to the first fixing block and the second fixing block, and then buckles the second baffle on the rotating shaft and fixes it by the first bolt, which is advantageous in that when the circular stack is worn, damaged or needs to be replaced, it can be easily disassembled so that maintenance personnel can easily remove the circular stack from the rotating shaft for maintenance or replacement without the need to disassemble or replace the entire rotating shaft.

At this time, the second transmission rod starts to rotate and drives the rotating shaft to rotate. At this time, the rotating shaft causes the stack to rotate for sludge dehydration. The transmission is carried out through the first conical tooth and the second conical tooth. Since the tooth profile of the conical tooth is conical, the meshing angle between the gear pairs is smaller, thereby improving the transmission efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
