Embodiment Construction
[0040] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations.
[0041] refer to Figure 1-Figure 5 As shown, an anti-clogging filter device for sewage treatment includes a filter cavity 1, a filter pipe 2 and a slag removal device 3 arranged in the filter pipe;
[0042] The filter cavity 1 is a cylinder, the filter cavity 1 has a water inlet 4 for introducing sewage, and the bottom of the filter cavity has a water outlet 5 for discharging filtered sewage;
[0043] The filter pipe 2 is arranged inside the filter chamber 1 and is coaxial with the filter chamber 1, and a gap is formed between the outer peripheral surface of the filter pipe 2 and the inner peripheral surface of the filter chamber 1 for accommodating filtration. after the sewage cavity;

The invention relates to the field of sewage treatment, in particular to an anti-blocking filtering device for sewage treatment, which comprises a filtering cavity, a filtering pipeline and a slag removal device, the slag removal device comprises a rotating rod, a scraper unit and a slag suction mechanism; one end of the rotating rod penetrates through the filtering pipeline and the filtering cavity and can rotate in the filtering pipeline and move back and forth in the filtering pipeline in the axis direction of the filtering pipeline; the scraper unit comprises a scraper, a buffer spring and a single rod; and the slag suction mechanism comprises a suction nozzle, a slag collecting opening, a suction pipe and a slag outlet. The scraper unit rotates and moves back and forth in the filtering pipeline along with the rotating rod to scrape filter residues on the filter screen, and the residue suction mechanism sucks and discharges the filter residues after the filter residues are scraped, so that the problem that the filter screen is still blocked due to incomplete scraping of the filter residues is solved, equipment does not need to be stopped, and the sewage filtering efficiency and the equipment operation efficiency are improved.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to an anti-clogging filter device for sewage treatment. Background technique [0002] The sewage generated by urban production and life is also increasing year by year, especially domestic sewage. Due to the large number of pollution sources and large discharge volume, urban sewage pipes are heavily loaded and often encounter problems of silting and blockage. [0003] In order to comply with the concept of saving and environmental protection, the domestic sewage is usually subjected to primary filtration treatment first, and then the subsequent treatment is carried out. The primary filtration is usually filtered by the filter screen, but due to the large amount of garbage in the raw sewage, the primary filtration process Among them, the filter screen is easily blocked by impurities, resulting in low sewage treatment efficiency, which in turn affects the normal operation of sewage tre...
