Description

A slag scraping device suitable for automatic adjustment of sewage treatment

technical field

The invention belongs to the technical field of sewage treatment, and specifically refers to a slag scraping device suitable for automatic adjustment of sewage treatment.

Background technique

In the sewage treatment sedimentation tank, sludge will be deposited at the bottom of the tank, and a lot of foam, foam and scum will be produced on the liquid surface. In the prior art, for the sludge at the bottom of the pool and the foam on the liquid surface, a running belt or a chain is used to convey a number of scrapers for treatment. The scrapers are generally fixedly connected to the running belt or chain, and are basically connected to the running belt Vertical state, and the length of the mud scraper is fixed. When working, the sprockets on both sides respectively drive the chain to rotate, thereby driving the mud scraper to rotate from top to bottom in the sedimentation tank, scraping the sludge at the bottom of the tank to the sludge tank, and scraping the scum on the liquid surface to the outlet. Slag mouth. However, when this structure is running, there are still the following problems:

1. Since the mud scraper is always in a state of being perpendicular or nearly vertical to the chain, the mud scraper is actually in a non-working state during the movement paths of the mud scraper from bottom to top and then from bottom to top, but the non-working state , the mud scraper will stir the sewage in the pool in the vertical direction, destroying the sedimentation effect;

2. The area of the part of the mud scraper in the sewage should be as small as possible to reduce the agitation of the mud scraper to the sewage, thereby reducing the damage to the sedimentation effect, but when the mud scraper scrapes the scum on the water surface , it should be a certain distance above the sewage surface to solve the problem that the thickness of the scum is too large, so that the scum passes over the upper side of the scraper, which affects the efficiency of scum scraping;

3. Since the height of the mud scraper is fixed, it is necessary to control the height difference between the sewage liquid level in the sewage treatment sedimentation tank and the running belt or chain, so that the mud scraper can scrape off the scum.

Therefore, according to the above problems, a slag scraping device suitable for automatic adjustment of sewage treatment can be designed.
