Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-5 A comprehensive sewage treatment and purification device for environmental engineering includes a filter tank 1, a side end of the filter tank 1 is connected to a water pipe 2, an end of the water pipe 2 away from the filter tank 1 is connected to a mixing tank 3, a tank cover 4 is installed on the top of the filter tank 1, a mounting frame 5 is installed on the bottom of the tank cover 4, a filter plate 6 is arranged inside the mounting frame 5, a cleaning mechanism 7 is arranged between the filter plate 6 and the filter tank 1, a stirring mechanism 8 is arranged in the mixing tank 3, and a top cover 13 is installed on the top of the mixing tank 3.

[0029] Specifically, the stirring mechanism 8 includes a stirring motor 801, the stirring motor 801 is installed on the top of the top cover 13, a main rotating rod 802 is installed at the output shaft of the stirring motor 801, a gear ring 803 is rotatably connected inside the top cover 13, a secondary rotating rod 804 is rotatably connected to the bottom of the top cover 13, a driving gear 805 is fixedly installed on the outside of the main rotating rod 802, a passive gear 806 is fixedly installed on the outside of the secondary rotating rod 804, a main stirring rod 807 is fixedly installed on the outside of the main rotating rod 802, an L-shaped mounting rod 808 is installed at the bottom of the gear ring 803, and the side end of the L-shaped mounting rod 808 is fixedly installed There is a secondary stirring rod 809. By turning on the stirring motor 801, the stirring motor 801 drives the main rotating rod 802 and the driving gear 805 to rotate. Since the driving gear 805 is meshed with the passive gear 806, the secondary rotating rod 804 and the passive gear 806 can be driven to rotate. Since the passive gear 806 is meshed with the gear ring 803, the gear ring 803 will be driven to rotate in the top cover 13. At this time, the stirring rod 807 and the secondary stirring rod 809 can rotate at the same time. The two stirring rods stir and mix the mixture in the mixing tank 3 at the same time, which can improve the mixing effect and thus reduce the mixing time.

[0030] Specifically, the cleaning mechanism 7 includes a rotating shaft 701, the rotating shaft 701 is installed through the middle of the tank cover 4, a dredging brush 702 is installed on the outside of the rotating shaft 701, a limiting groove 703 is provided on the top of the rotating shaft 701, two electric telescopic rods 704 are installed on the top of the tank cover 4, a connecting plate 705 is installed on the top of the two electric telescopic rods 704, a cleaning motor 706 is installed on the top of the connecting plate 705, a connecting rod 707 is fixedly installed on the output shaft of the cleaning motor 706, and a limiting block 708 is installed on the bottom of the connecting rod 707. By setting up the cleaning mechanism 7, when the filter holes on the filter plate 6 inside the filter tank 1 are blocked, the cleaning motor 706 can drive the unclogging brush 702 to rotate, and the filter holes are unclogged by the rotating unclogging brush 702, and driven by the electric telescopic rod 704, the limit groove 703 and the limit block 708 can be connected or disconnected, thereby controlling the movement state of the unclogging brush 702. When the tank cover 4 is removed to clean the filter plate 6, it is convenient to separate the rotating shaft 701 from the cleaning motor 706, reducing the inconvenience during disassembly.

[0031] Specifically, an observation window is provided on the outside of the filter tank 1, and there are three filter plates 6, which are arranged in sequence from top to bottom. A number of filter holes are evenly opened on the filter plates 6, and the apertures of the filter holes decrease from top to bottom. The first layer of filter holes intercepts some larger objects and soil, and the gaps between the second and third layers of filter holes become smaller and smaller, ensuring that the mud and sand content inside the sewage in the next step meets the standard.

[0032] The working principle of the present invention is as follows: first, sewage enters the filter tank 1 through the water inlet pipe 9 and is filtered by three filter plates 6 to prevent the sewage from containing too much sediment and affecting subsequent purification; then, the filtered sewage enters the mixing tank 3 through the water delivery pipe 2 for purification, and the purified liquid medicine in the medicine storage tank 11 enters the mixing tank 3 through the liquid outlet pipe 12 and mixes with the sewage. At the same time, in order to accelerate the mixing speed, the stirring motor 801 is turned on to drive the main stirring rod 807 and the secondary stirring rod 809 to rotate and stir together; finally, when it is observed that the filter hole is blocked, the electric telescopic rod 704 is controlled to drive the limit block 708 to move downward and insert it into the limit groove 703, so that the connecting rod 707 is connected to the rotating shaft 701, and then the cleaning motor 706 is turned on to drive the dredging brush 702 to rotate, so that the filter hole is dredged by the rotating dredging brush 702.

[0033] In summary, the comprehensive sewage treatment and purification device for environmental engineering, by setting a stirring mechanism 8, is provided with a main stirring rod 807 and a secondary stirring rod 809 in the mixing tank 3. The two stirring rods stir and mix the mixture in the mixing tank 3 at the same time, which can improve the mixing effect and thus reduce the mixing time. By setting a stirring motor 801, with the cooperation of the main rotating rod 802, the secondary rotating rod 804, the driving gear 805, the driven gear 806 and the gear ring 803, the main stirring rod 807 and the secondary stirring rod 809 can be driven to rotate together, which has strong practicality.

[0034] In addition, the comprehensive sewage treatment and purification device for environmental engineering is provided with a cleaning mechanism 7. When the filter holes on the filter plate 6 inside the filter tank 1 are blocked, the cleaning motor 706 can drive the dredging brush 702 to rotate, and the filter holes are dredged by the rotating dredging brush 702. Driven by the electric telescopic rod 704, the limit groove 703 and the limit block 708 can be connected or disconnected, thereby controlling the movement state of the dredging brush 702. When the tank cover 4 is removed to clean the filter plate 6, it is convenient to separate the rotating shaft 701 from the cleaning motor 706, reducing the inconvenience during disassembly and solving the problem that the mixing effect of the stirring rod of the comparative device is average and the mixing time is long when in use.
