A rotary sludge coating mechanism for sludge dewatering treatment system

Abstract

The purpose of the present invention is to provide a rotary mud coating mechanism for a sludge dewatering treatment system, which includes three parts: a mud coating lifting mechanism, a mud coating rotary workbench, and a mud coating vibration mechanism. When the rotary mud coating mechanism is working, the mud coating lifting mechanism drives the lifting platform to descend, so that the mud coating vibration mechanism approaches the filter cloth and all the sludge in it flows out onto the filter cloth. Afterwards, the mud coating rotary workbench rotates to move the other mud coating vibration mechanism to the working position, and the previously working mud coating vibration mechanism rotates to the standby position to load sludge and wait for the next rotation action. The present invention can make the two mud coating vibration mechanisms be used alternately through the rotation action, which saves the time of sludge loading and greatly improves the mud coating efficiency.

Description

Technical Field

[0001] The invention relates to the field of sludge dewatering treatment, in particular to a rotary sludge coating mechanism for a sludge dewatering treatment system. Background Art

[0002] Daily production and life generate large amounts of wastewater, and wastewater treatment produces significant amounts of sludge. Improper handling of this sludge can cause serious pollution. Therefore, the harmless treatment of sludge has always been a critical issue. Filter press dewatering is a common sludge dewatering technology. Before entering the filter press chamber, the sludge is first coated on a layer of filter cloth. During this process, the sludge passes through pipes and the mud outlet to reach the filter cloth. The sludge flow process takes time, and this time is a significant factor affecting the sludge coating.

[0003] In existing automated sludge treatment equipment, it takes time for the outlet to fill with sludge. Increasing the outlet area can improve sludge application efficiency, but this also places demands on the sludge's flow rate. To address this issue, the present invention provides a rotary sludge application mechanism for a sludge dewatering system. It features two outlets. While one outlet is operating, the other can be loaded with sludge, eliminating the need for time-consuming sludge loading. This solves the problem of slow sludge outflow and significantly improves sludge application efficiency. Summary of the Invention

The cylinder-piston connector 10 is connected to the lifting cylinder 5 at one end and to the lifting platform 9 at the other end. This mechanism can achieve the lifting and lowering of the sludge coating rotary worktable 2 and the mud coating vibration mechanism 3.

[0006] The mud coating rotary worktable 2 comprises a cylindrical gear 11, a slewing support 12, a fixed stopper 13, a rotating stopper 14, a stopper adjustment bolt 15, a hydraulic buffer 16, a brake reducer 17, a motor 18, and a rotating platform 19.

The inner ring of the slewing support 12 is bolted to the lifting platform 9, and its outer ring is also bolted to the rotating platform 19, and the outer ring meshes with the cylindrical gear 11. The fixed stopper 13 is bolted to the lifting platform 9; the stopper adjustment bolt 15 and the hydraulic buffer 16 are mounted on the fixed stopper 13; and the rotating stopper 14 is bolted to the rotating platform 19. This mechanism allows the mud coating vibration mechanisms 3 on both sides to be interchanged for alternate use.
