Description

Peripheral transmission mud scraper

Technical Field

The utility model relates to a peripheral transmission mud scraper, especially can carry out the mud scraper of all-round clearance to the sedimentation tank, belong to silt processing technology field.

Background

The peripheral transmission mud scraper is suitable for radial flow type primary or secondary sedimentation tanks of sewage treatment plants, and has the main function of scraping and collecting sludge settled at the bottom of the tank to a sludge collection pit and then discharging the sludge from a sludge discharge pipe so as to facilitate the backflow or concentration and dehydration of the sludge. The working bridge and the mud scraper can be divided into a full bridge type and a half bridge type according to different working bridges and mud scrapers. The working bridge of the main structural part is driven by a driving mechanism arranged on the periphery, a scraping arm which is hung under the working bridge and rotates around a central branch pipe arranged on a central buttress of the tank drags a logarithmic spiral scraper to rotate, sludge deposited at the bottom of the tank is collected to a central mud pit by the scraper, and then is discharged out of the tank by a mud pipe, scum on the liquid level is concentrated in a reduction area formed by a scum scraper and peripheral slag baffles, and the scum scraper scrapes the scum to a scum collecting hopper and then is discharged out of the tank.

No matter the full-bridge type or the half-bridge type, the sludge precipitated at the bottom of the sedimentation tank can only be collected and treated during operation, and the sludge is inevitably deposited or algae grows on the side wall of the sedimentation tank during long-time operation, so that the sewage treatment effect is influenced.

The utility model discloses a scraper blade is hollow structure, in the operation of working bridge, does not increase the running resistance of working bridge.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the wall scraping device of the present invention.

In the drawings, the respective reference numerals denote: 1. the device comprises a driving device, 2, a working bridge, 3, a central support, 4, a guide cylinder, 5, a traveling frame, 6, a sedimentation tank, 7, a wall scraping device, 8, a mud collecting pit, 9, a mud scraping plate, 10, a spring, 11, a scraping plate, 12 and a brush.

Detailed Description

Referring to the attached drawing 1, the utility model discloses a central support 3, the outside of central support 3 is provided with draft tube 4, central support 3 be provided with all around album mud hole 8, the mud hole 8 of album is provided with sedimentation tank 6 all around, the lower extreme of central support 3 is provided with the sewage inlet tube, one side of album mud hole 8 is provided with the mud pipe, the top of central support 3 is provided with working bridge 2, and working bridge 2's both ends all are provided with drive arrangement, and drive arrangement 1 driving wheel walks at 6 borders of sedimentation tank, 2 bottoms of working bridge are equipped with truss 5, and truss 5 bottoms set up mud scrapping plate 9, are equipped with wall scraping device 7 on truss 5 in the outside.

The sewage is diffused by a guide cylinder from a water inlet pipe in the center of the pool and uniformly flows out radially to the periphery, suspended sludge is deposited at the bottom of the pool after being precipitated, supernatant is discharged out of the pool by a water outlet groove, a sludge scraper is discharged out of the pool from a pool Zhou Gua to a central sludge collecting pit, and the sludge is discharged out of the pool by a sludge discharge pipe depending on the water pressure in the pool.
