DETAILED DESCRIPTION

[0026] The present utility model will now be described in further detail in conjunction with the drawings.

[0027] Please refer to Figures 1-5 shown, in the present embodiment, a municipal sewage treatment device is provided, comprising: a sewage treatment tank 1 and a tank cover 2, the tank cover 2 is located above the sewage treatment tank 1, the sewage treatment tank 1 is internally provided with a water inlet and a water outlet on both sides respectively, a filter assembly 3 corresponding to the water outlet is arranged on one side of the sewage treatment tank 1, and a connecting pipe 4 is connected between the filter assembly 3 and the water inlet.

[0028] The movable plate 6 is slidably fitted in the sewage treatment tank 1, a linear drive 5 connected with the movable plate 6 is arranged on one side of the inner wall of the sewage treatment tank 1, the scraper 7 is slidably and elastically fitted on the lower side of the movable plate 6, an inclined block 9 is arranged on one side of the inner wall of the sewage treatment tank 1, and an elastic abutting assembly 10 corresponding to the inclined block 9 is arranged on one side of the scraper 7, wherein the linear drive 5 can be an existing electric slide rail or a linear motor.

[0029] An aspect of the embodiment is applied as follows: when filtering the sewage in the sewage treatment tank 1, the linear driving member 5 is started to drive the movable plate 6 to move, the movable plate 6 drives the scraper 7 to move, the scraper 7 moves to scrape the sewage impurities precipitated in the sewage treatment tank 1 to the water outlet, the discharged sewage impurities are filtered by the filtering assembly 3, and the filtered sewage reenters the sewage treatment tank 1 through the water inlet by the connecting pipe 4. When the linear driving member 5 drives the scraper 7 to reset through the movable plate 6, the scraper 7 is driven to move upward and reset by the abutment of the elastic abutment assembly 10 and the inclined block 9, so that the unscraped sewage impurities can be repeatedly scraped.

[0030] The linear driving member 5 is arranged to drive the scraper 7 to scrape the sewage impurities precipitated in the sewage treatment tank 1 to the water outlet, the discharged sewage impurities are filtered by the filtering assembly 3, and the filtered sewage is reduced to reduce the incomplete filtration of the sewage impurities precipitated in the sewage treatment tank 1. The elastic abutment assembly 10 is arranged to drive the scraper 7 to move upward and reset by the abutment of the elastic abutment assembly 10 and the inclined block 9 when the movable plate 6 drives the scraper 7 to reset, so as to reduce the situation that the unscraped sewage impurities are brought back to the original place when the scraper 7 resets, thereby improving the scraping effect of the sewage impurities.

[0031] As shown in Figure 3 The filtering assembly 3 of the embodiment includes a separation tank 301 arranged on one side of the sewage treatment tank 1 and penetrating the water outlet, a slot opening on one side of the separation tank 301, a filter box 302 arranged in the slot, a water pump 303 arranged on one side of the bottom of the separation tank 301, a through hole corresponding to the water inlet of the water pump 303 is arranged on one side of the bottom of the separation tank 301, and the connecting pipe 4 is arranged between the water pump 303 and the water inlet.

[0032] The filtering assembly 3 is arranged to allow the sewage impurities to fall into the filter box 302 through the water outlet for filtration, the filtered sewage flows into the bottom of the separation tank 301 after being filtered by the filter box 302, the sewage in the separation tank 301 is injected into the connecting pipe 4 by the water pump 303 through the through hole, and the sewage in the connecting pipe 4 reenters the sewage treatment tank 1 through the water inlet, so as to facilitate the circulation filtration of the sewage.

[0033] As shown in Figures 4-5As shown, the movable plate 6 in this embodiment has a groove on its lower side, and the scraper 7 is slidably fitted in the groove. A plurality of first elastic elements 8 are installed between the groove and the scraper 7. The first elastic elements 8 are springs or elastic telescopic rods in the prior art. The elastic abutment assembly 10 includes a groove 1001 opened on one side of the scraper 7, a slider 1002 slidably fitted in the groove 1001, a second elastic element 1004 installed between the slider 1002 and the groove 1001, and an abutment block 1003 installed on one side of the slider 1002. The abutment block 1003 has a chamfer on its lower side that abuts against the upper inclined surface of the inclined block 9. The second elastic element 1004 is a spring or elastic telescopic rod.

[0034] When the linear drive 5 drives the scraper 7 to scrape sewage impurities through the movable plate 6, when it moves to the position of the inclined block 9, the lower inclined surface of the inclined block 9 presses the slider 1002 to move downward in the groove 1001. After the scraper 7 moves past the inclined block 9, the slider 1002 is reset by the elastic force of the second elastic member 1004.

[0035] When the linear drive 5 drives the scraper 7 to reset via the movable plate 6, the inclined surface on the upper side of the inclined block 9 moves upward by pressing the chamfer on the lower side of the abutment block 1003. The upward movement of the inclined block 9 drives the scraper 7 to move upward via the limit of the slider 1002 on one side of the slide groove 1001. After the scraper 7 moves past the inclined block 9, the scraper 7 is reset by the elastic force of the first elastic member 8 and re-fits against the bottom of the inner wall of the sewage treatment tank 1. This allows for repeated scraping of the unscraped sewage impurities, reducing the situation where the scraper 7 brings the unscraped sewage impurities back to their original position when resetting, thereby improving the scraping effect of sewage impurities.

[0036] like Figure 1 As shown, threaded holes are provided at the upper corners of the sewage treatment tank 1 in this embodiment, and fastening bolts 11 corresponding to the threaded holes are threaded on the upper side of the tank cover 2. The fastening bolts 11 can detach and install the tank cover 2 on the sewage treatment tank 1, thereby facilitating the cleaning of the inside of the sewage treatment tank 1.

[0037] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
