Shandong Ningye Machinery Equipment Co., Ltd. is one of the leading manufacturers and suppliers of vertical frame central drive sludge scraper in China. With a professional production team, we are able to meet the needs of the majority of our customers. Please feel free to buy durable vertical frame central drive sludge scraper at low price from our factory.
Our Vertical Frame Central Drive Sludge Scraper is specially designed for sludge treatment in circular sedimentation tanks. Its core functions are sludge scraping, conveying at the tank bottom and scum removal on the tank surface. It is suitable for various circular sedimentation tanks, secondary sedimentation tanks and clarifiers, and is widely used in municipal, industrial, tap water treatment and other fields to meet customers' diverse sludge treatment needs.
The core of the equipment consists of a central drive device, a transmission vertical frame, a scraper arm truss, a sludge scraper, a rectifier diffuser, a draft tube, a scum skimming device and a working bridge, which work together to realize synchronous treatment of sludge and scum.
During operation, the central drive device on the tank top drives the vertical frame and scraper arm to rotate at a constant speed through a reducer. After the sewage is uniformly distributed through the central column pipe and rectifier diffuser, suspended solids settle at the tank bottom. The sludge scraper scrapes the sludge from the tank circumference to the central sludge collection hopper and discharges it by static water pressure; the scum on the tank surface is scraped to the scum discharge hopper by the scum skimmer and discharged, and the supernatant overflows through the outlet weir plate to realize the separation of mud, water and scum.
Core Product Features and Advantages
1. Reasonable Structure:
The vertical frame central drive design is compact, facilitating the erection of the sedimentation tank deodorization cover. The scraper arm has a short cantilever and the main shaft is rigidly supported, with strong vibration resistance, suitable for working conditions with many sludge particles.
01
2. Reliable Operation:
It adopts a vertical three-stage cycloidal pinwheel reducer with large torque and stable operation. The low-speed design (0.3~1.0r/min) avoids impacting the tank bottom, and it is equipped with double overload protection to reduce the failure shutdown rate.
02
3. Corrosion Resistance and Durability:
Underwater components are made of stainless steel or anti-corrosion coating to resist corrosive substances, and the service life can reach 15~20 years under normal maintenance.
03
4. Thorough Sludge Scraping:
The diagonal sludge scraper has high sludge collection efficiency, and the rubber scraper at the bottom fits closely with the tank bottom, with no floating sludge residue, improving the sedimentation effect.

5. Low energy consumption, easy operation and maintenance:
The device has low power consumption. The drive and maintenance components are located at the top of the fuel tank, so there is no need to empty the tank for maintenance. Vulnerable parts are modular and easy to replace.

Functional Features and Application Scenarios
Core Functions:
Scraping, collecting and conveying sludge at the tank bottom, skimming scum on the tank surface. It can be equipped with a lifting device and a torque alarm system, and some models can scrape and suck at the same time to improve the sludge discharge effect.
Application Scenarios:
Suitable for circular sedimentation tanks with central water inlet, peripheral water outlet and central sludge discharge, covering municipal sewage, tap water plants, chemical industry and other industrial fields. It is suitable for small and medium-sized tank bodies with a diameter ≤ 20 meters to large and medium-sized tank bodies, and can handle medium-concentration sludge with a water content of 95%~98%.
