YOSUN CENTRAL DRIVE SCRAPER FOR SLUDGE THICKENER consists of arms fitted on a centre tube. There are angled scraper blades welded under the arms for bottom scraping. The drive unit is located on a fixed bridge, and the gear is directly connected to the centre shaft, the lower part of which is equipped with a bottom bearing to prevent abrasion caused by friction. Fixed bridge circular scrapers remove settling sludge from the circular sedimentation basin during operation.
Those settling materials which cannot sink directly into the collecting hopper are pushed towards the hopper at the centre using rotating blades. Clearwater is collected in the collection channels. Sludge collected in the hopper is removed from the system through a discharge pipe.
Working principle of sludge scraper（Video Description）
How Sludge scraper works ？
The working principle of the Sludge scraper: When the Sludge scraper is working, the working bridge is driven by the driving mechanism installed on the periphery and rotates around the central support installed on the central pier of the pool. The Sludge scraping device installed on the working bridge rotates. During the process, the sludge settled at the bottom of the tank is scraped to the sludge collecting bucket in the center of the tank.
When the scraper encounters excessive sludge hardening or obstacles, it generates excessive resistance. When the torque produced by the resistance on the hinge is greater than the torque produced by the pressure of the scraper device on the hinge, the scraper and the truss will rotate around. When the hinge rotates, the spring on the pressure regulator will also be compressed, and the scraper can adjust itself to pass over obstacles, ensuring the safety of the equipment when scraping Sludge and effectively absorbing shock.
Generally, when sludge hardens or settles too quickly, only a very small thickness of the sludge layer can be scraped off. At this time, when the scraping speed cannot keep up with the sludge deposition speed, the adjusting nut on the pressure regulator can be adjusted. Make the spring generate greater compression force, thereby exerting greater downward pressure on the Sludge scraper device, which can increase the Sludge scraper thickness and speed up the scraping speed. In contrast, the speed of the Sludge scraper remains unchanged. Remove sludge promptly and effectively.

| 1. The wastewater enters the system through the inlet pipe. | 2. The solid materials present in the water spread around the tank and they start to settle at the tank bottom. Thus, it is needed to remove the sludge accumulated at the bottom. | 3. The central-driven fixed bridge circular scraper starts to move and scrape the materials at the bottom by the scraper blades connected with the shaft. The sludge scraped is collected into a hopper and removed from the system. |
What types of sludge scrapers are there?
Sludge scrapers are the main processing equipment responsible for mud discharge and skimming functions. They are generally divided into four categories:
peripheral drive scrapers (GA),
central drive scrapers (GZ),
and truss scrapers (GH)，
chain drive type mud scraper (GL).
The main equipment suitable for the radial flow sedimentation tank of medium and large tanks is the peripheral drive mud scraper. At present, the scraping devices of most peripheral drive scrapers are divided into two types: fixed type and drag type.
Sludge scrapers Advantages
High efficiency: Because the transmission mechanism of the center drive scraper is located in the center of the waste pool or water treatment equipment, it can achieve a more uniform and efficient mixing effect and promote the separation of the mixture and the solid-liquid separation process.
Strong stability: Mud scrapers with a central transmission design are generally more stable and reliable, less susceptible to external factors, and can maintain stability and continuity of operation.
Small space occupied: Compared with other types of scrapers, center drive scrapers are usually compact in design and occupy small space, making them suitable for water treatment systems with limited space.
Easy maintenance: The center drive scraper has relatively few transmission parts, making it easy to maintain and repair, reducing maintenance costs and repair time.
Multiple choices of transmission reducer: the three-stage cycloid reducer is directly driven, with a simple and compact structure and convenient maintenance; lt is driven by the reducer, transmission gear, and rotary bearing which can obtain great driving torque and is suitable for heavy-duty occasions.
The safe and reliable outdoor-type control cabinet can be controlled randomly and remotely.
Size, material, and other configurations of the equipment can be customized.
