Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device for environmental engineering. Background Art

[0002] Sewage refers to unclean water, domestic sewage, urban sewage, and discarded liquid transported by sewage pipes. Sewage has lost its original function and can be defined as liquid or water carrying waste mixed with groundwater, surface water, blizzards, etc. discharged from residential, institutional, commercial or industrial areas. Sewage contains more organic matter and is easier to handle.

[0003] The patent with the patent authorization announcement number CN216687714U discloses a sewage treatment tank for sewage treatment equipment, including a mobile device, a stirring device and a filtering device, wherein the mobile device includes a base, rollers are installed on both the left and right sides of the bottom of the base, and a push rod is installed on the right side of the base. Although the above patent can crush the impurities in the sewage by setting a motor and a stirring blade to prevent the impurity discharge port from being blocked, there are still deficiencies in actual use. For example, in the process of treating sewage, when there are too many impurities accumulated on the filter net, in order to ensure the filtering effect of the filter net, the filter net must be cleaned on the way, and the filter net is located in the lower part of the sewage treatment tank body, so the filter net is completely immersed in the sewage, resulting in the cleaning brush brushing the impurities on the surface of the filter net. The impurities are easily affected by the sewage and float, resulting in poor cleaning effect of the cleaning brush.

[0004] Therefore, there is a particular need for a sewage treatment device for environmental engineering to solve the problems existing in the prior art. Utility Model Content

[0030] See also Figure 1 , Figure 2 and Fig. 9 As shown, it also includes a third motor 24, a stirring plate 25 and a pulley assembly 26. The third motor 24 is connected to the right side of the bottom of the shell 2 by bolts. The inside of the shell 2 is rotatably connected with stirring plates 25 distributed on the left and right for stirring sewage. The output shaft of the third motor 24 penetrates into the inside of the shell 2 and is connected to the stirring plate 25 on the right. A pulley assembly 26 is provided between the lower ends of the two stirring plates 25. The third motor 24 is operated to rotate the stirring rod on the right side, so that the stirring rod drives the stirring plate 25 on the left side to rotate through the pulley assembly 26.

[0031] First, the staff introduces sewage into the shell 2 from the water inlet 3, and introduces the purifier into the shell 2 from the medicine inlet 4, so that the sewage and the purifier are in contact and mixed, so that the sewage is purified by the purifier. When the sewage is introduced into the shell 2, it contacts the filter 10, and the filter 10 filters the sewage, so that garbage and other impurities in the sewage remain on the surface of the filter 10, and the filtered sewage flows into the lower part of the shell 2. Then the third motor 24 is turned on, and the output shaft of the third motor 24 rotates to drive the stirring plate 25 on the right to rotate, so that it drives the stirring plate 25 on the left to rotate through the pulley assembly 26, so that the stirring plates 25 on both sides rotate at the same time to stir the sewage and the purifier, so that the sewage and the purifier are fully mixed. In this way, a good treatment effect is achieved. During the stirring process, the purified sewage is discharged from the water outlet 27. When the filter screen 10 needs to be cleaned, the staff turns on the first motor 5. The output shaft of the first motor 5 rotates to drive the first gear 6 to rotate, so that it meshes with the second gear 7, and then the second gear 7 drives the threaded rod 8 to rotate, so that the filter screen 10 moves upward to a suitable position, and then the filter screen 10 is lifted to the surface of the sewage, which is convenient for the subsequent scraper 15 to fully scrape off the garbage and other impurities on the surface of the filter screen 10, thereby ensuring the cleaning effect. The staff turns off the first motor 5 and then turns on the second motor 12. The output shaft of the second motor 12 rotates to drive the bidirectional screw rod 13 to rotate, so that the scraper 15 moves forward. The scraper 15 is used to scrape away garbage and other impurities on the surface of the filter 10. When scraping, the garbage and other impurities are pushed into the collection box 23 for drainage. In the process of filtering sewage, plastic bags will remain on the surface of the filter 10 in the sewage. When the scraper 15 moves forward, it drives the outer cylinder 16 to move forward, so that the third gear 17 is engaged with the rack 22, and then the third gear 17 drives the inner cylinder 18 to rotate, so that the cone block 21 is intermittently squeezed by the outer cylinder 16 to move upward and retracted in the inner cylinder 18, and the spring 19 is compressed accordingly, and the third gear 17 continues to drive the inner cylinder 18 to rotate, so that the cone block 21 is intermittently aligned with the opening 1601, and the spring 19 returns to its original state, so that the cone block 21 moves downward and pops out from the inner cylinder 18, and then pierces the filter 1 0 on the garbage bag on the surface of the filter screen 10, so that before the cone block 21 is retracted into the inner tube 18, the garbage bag is lifted from the surface of the filter screen 10, so as to facilitate the scraper 15 to scrape the garbage bag, further ensuring the cleaning effect. When the scraper 15 moves forward to the limit, the staff controls the output shaft of the second motor 12 to reverse, thereby driving the bidirectional screw rod 13 to reverse, so that the scraper 15 moves backward to reset, and then turns off the second motor 12. Then the staff restarts the first motor 5, controls the output shaft of the first motor 5 to reverse, and then makes the first gear 6 reverse and mesh with the second gear 7 in the opposite direction. The second gear 7 drives the threaded rod 8 to reverse, so that the filter screen 10 moves downward to reset and immerse in the sewage. The staff turns off the first motor 5.
