Central transmission scraper

The raw water from the central transmission scraper is distributed through the central water distribution cylinder and flows radially towards the overflow tank around the pool. As the flow rate decreases, suspended solids in the water are separated and settle at the bottom of the pool. The supernatant is discharged from the outlet tank through the overflow weir plate.

Working principle

Through deceleration drive and transmission of suspended components, the sludge is scraped by a scraper to the central sludge collection tank, and discharged outside the tank by static water pressure or pump. Adopting middle water inlet and sludge discharge, and surrounding drainage to ensure uniform water flow. Utilizing liquid level difference self-priming sludge discharge, equipped with floating slag scraping and removal device and overload protection device.

characteristic

1. The transmission part adopts dual electrical and mechanical overload protection, making operation safer and more reliable.

2. The underwater part is made of stainless steel, which is corrosion-resistant and has a long service life.

Main structure

The transmission scraper of this center is mainly composed of a driving device, a main shaft, railings, steel beams, vertical bars, supports, scraper plates, overflow weir plates, pull rods, small scrapers, underwater bearings, stabilizing tubes, electric control boxes and other components.

application area 

Our transmission scraper can be widely used in sewage treatment projects in urban, chemical, textile, metallurgical and other industries. Its structure is reasonable, efficient, and easy to operate and maintain, making it an ideal supporting facility for sewage treatment projects.

Performance

(1) The bottom of the pool is scraped with mud, and the driving device adopts a deceleration driving mechanism for transmission, with a compact structure and high mechanical efficiency;

(2) Diagonal scraper with good continuity and high efficiency in collecting mud; Install a scraper rubber plate underneath the stainless steel scraper plate to ensure thorough cleaning of the scraper and prevent any floating mud.

(3) The slope ratio of the pool bottom is 1:10, and the sludge resistance during scraping can be ignored.

(4) The main beam is made of square steel with high structural strength. It adopts hot-dip galvanizing and then spray coating technology, which has strong anti-corrosion performance. The main beam can also be directly poured with concrete, which saves more investment.

(5) Easy to operate and capable of remote control.

Main technical parameters of the equipment

structural style

The BYZXN center drive scraper mainly consists of a deceleration drive mechanism, a transmission vertical shaft, a scraper arm, a concentration grid bar, and a mud collection tank scraper. The load of the entire concentrator is applied to the center of the fixed working bridge spanning the pool diameter.
