Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment sedimentation and collection device. Background Art

[0002] Sewage is a source of pollution. In order to reduce the pollution of sewage to the environment, the discharged sewage must be treated before being discharged. The sewage treatment process is to first remove the suspended pollutants in the wastewater, add flocculants, and after stirring, agglomerate them with fine particles and natural colloids in the water into large flocs. The generated flocs are filtered to obtain relatively clean wastewater. Finally, the metal ions in the wastewater are recovered to make the wastewater meet the sewage discharge standards.

[0003] In the prior art, when filtering large flocs generated in water, since the large flocs have different specifications, in order to prevent the flocs from passing through the filter element, a small-pore filter is used for filtration. After filtering through the filter, the filtered flocs adhere to the surface of the filter. As the filtration continues, the flocs on the surface of the filter gradually increase, and the flocs cover the filter holes on the filter, causing the filter to lose its filtering effect and the wastewater to be unable to pass through the filter. In order to ensure the process effect of the filter while the wastewater treatment is still in progress and the device cannot be opened to clean the filter, a scraping mechanism is used to scrape the surface of the filter to separate the flocs from the filter, so that the wastewater can pass through the filter.

[0004] Patent application number: CN202221919772.1 discloses a mixing station sewage treatment equipment, including a treatment pool for treating mixing station sewage, an overflow plate is provided in the treatment pool, the overflow plate separates the treatment pool into a sewage tank and a clean water tank, a slag discharge pipe is provided in the sewage tank, a first valve is provided on the slag discharge pipe, a filter plate is provided on the overflow plate, a plurality of filter holes are provided on the filter plate, a bracket is provided on the treatment pool, a scraper is provided on the bracket for sliding along the length direction of the filter plate, the scraper is used to abut against the side wall of the filter plate close to the sewage tank, and a drive component for driving the scraper to slide is provided on the bracket. The impurities on the filter plate are cleared by sliding the scraper, but since the flocs are cotton-like, after being filtered out by the filter plate, part of the flocs are on the filter plate, and the other part of the flocs pass through the filter plate. In order to protect the filter plate, when the scraper scrapes the surface of the filter plate, the extrusion strength between the scraper and the filter plate is small, and the hardness of the flocs is low. When the filter plate scrapes the filter screen, the scraper will cut off the flocs. Under the impact of sewage, a part of the flocs stuck in the filter screen holes pass through the filter screen and are released together with the wastewater, affecting the filtration efficiency.

[0005] The present invention is proposed in view of the deficiencies in the prior art. Summary of the Invention

[0013] Preferably, the frame is further secured to a plurality of cylinders, the piston rods of the cylinders being fixed to fixed blocks, and a scraper rod for use with the drum being secured to the bottom of the fixed blocks. After impurities are spun off by the drum and adhere to the inner wall of the drum, the cylinders are activated, the piston rods on the cylinders shorten, and the scraper rods move closer to the inner wall of the drum. After the scraper rods contact the inner wall of the drum, the rotary motor drives the drum to rotate, and the impurities adhering to the inner wall of the drum are separated from the drum and fall to the bottom of the drum.
