Description

Technical Field

[0001] The utility model relates to the technical field of sludge tank equipment, in particular to a sludge scraper position controller. Background Technique

[0002] A sludge scraper is a device used to handle sludge in a sedimentation tank or sedimentation trough, and is widely used in sewage treatment plants and industrial wastewater treatment systems. The role of the position controller in the sludge scraper system is to control the movement and position of the sludge scraper.

[0003] The traditional position controller is composed of a cylinder body, a travel switch, a linkage rod, a locking assembly and a pressing part. When in use, the position of the position controller is fixed through the locking assembly, and then the linkage rod is used to connect the position controller with the sludge scraper. When the sludge scraper moves, it drives the linkage rod to move, and the moving linkage rod drives the pressing part to move. When the pressing part moves to touch the travel switch, the travel switch is used to detect the moving distance of the sludge scraper. During the long-term use of the spring, due to continuous extrusion, the spring will produce tiny cracks and eventually break. After the spring is installed, both ends of the cylinder body are welded and sealed. When the spring is deformed or broken, the assembly loses the elastic connection effect, and the original component spring cannot be taken out, and only the whole needs to be replaced, thus causing waste of resources.
