Description

A central drive concentrator

technical field

The utility model relates to the field of water treatment equipment, in particular to a central drive concentrator.

Background technique

The scraper and suction sludge machine is a large-scale sludge discharge device, which is mainly suitable for radial flow sedimentation tanks with a diameter of >15 meters in sewage treatment plants or water works. After that, it diffuses into the sedimentation tank; the settled sludge is scraped by the scraper to the suction port, and the sludge at the bottom of the tank is sucked into the sludge discharge tank by the suction pump; finally, the sludge is discharged by hydrostatic pressure. Most of the traditional bridge-type scraper-suction machines use gear transmission to drive the machine to rotate. In order to obtain a relatively large reduction ratio, a reducer is generally installed to adjust the speed. The noise is loud during operation and the failure rate is high.

Contents of the invention

Purpose of the invention: The purpose of this utility model is to provide a central drive concentrator for the deficiencies of the prior art.

Technical solution: In order to achieve the purpose of the above invention, the utility model is specifically accomplished as follows: a central drive concentrator, including a sedimentation tank, a driving device is arranged in the center of the sedimentation tank, fixed on the working platform above the sedimentation tank, The driving device is connected with the central main shaft. The upper part of the central main shaft is connected with a steady flow cylinder, and the lower part is connected with a scraper frame. The bottom of the mud frame is connected with a mud scraper, and a mud discharge port is arranged at the bottom of the sedimentation tank.

In order to facilitate sludge storage, the center of the bottom of the sedimentation tank is an inverted trapezoid.

In order to improve the mud scraping effect, the mud scraper is parallel to the bottom of the sedimentation tank, and the taper is 1:6-8.

In order to connect the scraper and the scraper frame more firmly, a plurality of steel bars are welded on the scraper frame.

Beneficial effects: Compared with the traditional technology, the utility model saves electricity compared with the equipment of the same specification; the sludge discharged has a high concentration and the sludge discharge effect is good; the scraper has a simple structure, is not easy to be blocked, is safe and reliable in operation, and has low noise.
