Peripheral drive sludge scraper

I. Purpose:

Peripheral drive scrapers are suitable for radial flow primary or secondary sedimentation tanks in wastewater treatment plants. Their main function is to scrape the sludge settled at the bottom of the tank into a sludge collection pit, and then discharge it through a sludge discharge pipe for sludge return or thickening and dewatering. Depending on the situation, a surface scraping mechanism can also be installed to collect surface scum and discharge it outside the tank through a scum funnel.

II. Model Description:

three,Features:

1The working bridge adopts a truss structure, which is simple, beautiful and lightweight.

2It is simple and convenient to maintain, and has low operating costs.

3Multiple options for transmission reducers: shaft-mounted type, simple and compact structure, easy to maintain; cycloidal pinwheel reducer, inexpensive, high-quality, and efficient transmission.

4． Depending on user needs, engineering rubber wheels can be selected as the wheel surface material (standard configuration).Steel wheels, nylon wheels, polyurethane wheels

Ester wheel.

5． Highly efficientThe logarithmic spiral scraper ensures the reliability of sludge scraping and collection.

6． All electrical components are outdoor type, safe and reliable, and can be controlled randomly or remotely.

7． The equipment can be manufactured to user-specified dimensions. Parts that come into contact with water can be made of stainless steel.

Four,Structure and working process:

Peripheral drive sludge scrapers can be divided into two types based on the difference in the working bridge and scraper blades: full-bridge and half-bridge. A full-bridge peripheral drive sludge suction machine is shown in Figure 1.As shown in the figure, the semi-bridge peripheral drive sludge suction machine2As shown.

The peripheral drive sludge scraper consists of main components such as a working bridge, scraper arm and scraper blade assembly, central support, drive mechanism, collector, and electrical control box, as well as accessories such as an outlet triangular weir, flow stabilizer, baffle plate, and scum scraper.Whether to provide it shall be determined through negotiation between both parties.)composition.

The working bridge is driven by a peripheral drive mechanism, rotating around a central support mounted on a central pier in the pool. It is suspended...

The scraper arm under the working bridge drives the logarithmic spiral scraper to rotate, and the sludge settled at the bottom of the pool is collected by the scraper to the central sludge collection pit. The scum on the liquid surface is concentrated in the gradually narrowing area formed by the scum scraper and the surrounding baffle plates, and is scraped by the scum rake to the scum collection hopper and discharged out of the pool.
