Problems solved by technology

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.

Abstract

The invention discloses a center driving thickener, which comprises a sedimentation basin. A drive unit is arranged at the center of the sedimentation basin and fixed on a working platform above the sedimentation basin. The drive unit is connected to a center spindle, the upper part of which is connected with a steady flowing barrel and the lower part of which is connected with a scraper rack. A water inlet pipe is communicated with the steady flowing barrel through the center spindle. The upper end of the steady flowing barrel is provided with an overflow pipe. The bottom of the scraper rack is connected with a scraper. The bottom of the sedimentation basin is equipped with a sludge discharge port. In comparison with the prior art, the invention has the following advantages: the equipment of the invention is power-saving than equipment of the same specification; concentration of discharged sludge is high and the sludge discharge effect is good; the scraper structure is simple, and obstruction is not easily caused; operation is safe and reliable; and noise is low.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a central drive concentrator. Background technique [0002] 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 [0003...
