Description

Technical Field

[0001] The utility model belongs to the technical field of chemical industrial wastewater treatment, and particularly relates to a filtering and slag removing device for industrial wastewater treatment. Background Art

[0002] In the field of chemical industrial wastewater treatment, an efficient slag removing and filtering process is crucial for ensuring the up-to-standard discharge of wastewater. Although the current technology for replacing and cleaning filter plates has been relatively mature, there is still a problem that the cleaning mechanism rotates on the filter plate and rubs against the filter plate, squeezing some waste residues equal in size to the filter holes into the filter holes, resulting in blockage of the filter plate.

[0003] After retrieval: The prior art publication number: CN221752432U, a slag remover for chemical industrial wastewater, includes a device main body with a cavity formed therein. Four support columns are evenly arranged along the circumferential direction at the bottom of the device main body, and anti-slip foot pads are provided at the bottoms of the support columns. This prior art realizes the replacement of the filter plate and the cleaning rod fluctuates on the filter plate for stirring, but does not clean the waste residues on the filter plate in time. Excessive accumulation of waste residues on the filter plate will cause the following problems: (1) The filtering capacity of the filter plate decreases, resulting in a reduction in the wastewater treatment efficiency; (2) The cleaning rod fluctuates on the filter plate and rubs against the filter plate, squeezing some waste residues equal in size to the filter holes into the filter holes, causing blockage of the filter plate.

[0004] Further retrieval: The prior art publication number: CN221601401U, a chemical industrial wastewater treatment device, includes a filtering barrel with a filter net arranged therein. A sewage discharge port is formed on the side of the filtering barrel. The sewage discharge port is located above the filter net and is close to the filter net. The filtering barrel is communicated with a sewage discharge pipe through the sewage discharge port. It also includes a first stirring mechanism, a second stirring mechanism and a scraper. The upper end of the first stirring mechanism is fixedly connected to the upper surface of the filtering barrel. The lower end of the first stirring mechanism passes through the upper surface of the filtering barrel and is inserted into the interior of the filtering barrel. The first stirring mechanism is located inside the filtering barrel, and the first stirring mechanism is rotatably connected to the second stirring mechanism through a connecting member. The lower end of the first stirring mechanism is fixedly connected to the scraper, and the lower surface of the scraper abuts against the upper surface of the filter net. Although this prior art can push the waste residues on the filter plate into the sewage discharge port through the scraper, there is still a problem that the scraper rotates on the filter plate and rubs against the filter plate, squeezing some waste residues equal in size to the filter holes into the filter holes, causing blockage of the filter plate. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a filtering and slag removing device for industrial wastewater treatment. The waste residues attached to the surface of the filtering mechanism are efficiently cleaned through a scraper mechanism, and the filtering mechanism is vibrated through a vibration mechanism to shake out the waste residues squeezed into the filter holes while accelerating the filtration of wastewater, thereby effectively avoiding the problem of blockage of the filter holes by waste residues and improving the filtration efficiency and wastewater treatment effect.
