DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Combination Figures 1 to 3 Shown:

[0020] A sedimentation tank for sewage treatment comprises a first filter tank 1 and a second filter tank 2, a partition plate 3 is arranged between the first filter tank 1 and the second filter tank 2, scrapers 4 are arranged oppositely on both sides of the partition plate 3, a water inlet 11 is arranged at one end of the first filter tank 1, a water outlet 21 is arranged at the same end of the second filter tank 2, an inclined plate 12 is arranged on the inner wall of the first filter tank 1 below the water inlet 11, a first filter plate 13 is arranged on the inner wall of the first filter tank 1 at a position opposite to the inclined plate 12, a second filter plate 22 is arranged on the inner wall of the second filter tank 2 at a position opposite to the partition plate 3, a sewage outlet 5 is arranged at the bottom of the outer side walls of the first filter tank 1 and the second filter tank 2, and a sewage discharge device is arranged outside the sewage outlet 5.

[0021] The sewage discharge device includes a sewage trough 51, which is connected to the sewage outlet 5. A lifting groove 52 is opened on the upper side of one side of the sewage trough 51. A sealing lifting plate 53 is arranged in the lifting groove 52, which cooperates with the scraper to seal the sewage discharge device and separate it from the sewage. A sliding groove 54 is opened on the side plate on the other side of the sewage trough 51. A sliding sealing plate 55 is arranged in the sliding groove 54 for sealing the sewage outlet 5.

[0022] Several fixed blocks 6 are arranged on the outer wall of the No. 1 filter tank 1 and the No. 2 filter tank 2. Hydraulic telescopic rods are arranged on both sides of the bottom of the fixed blocks 6 to respectively connect the sealing lifting plate 53 and the sliding sealing plate 55 for controlling the lifting and lowering of the sealing lifting plate 53 and the sliding sealing plate 55. A concave sludge discharge plate 56 is arranged on the outer side of the sewage discharge trough 51 for the final sludge discharge. The lifting trough 52 and the sealing lifting plate 53 are attached to the outer side of the sewage discharge port 5.

[0023] The top of the partition 3 is in the shape of a filter screen for sewage circulation, and the bottom is a solid plate to separate the No. 1 filter tank 1 and the No. 2 filter tank 2. Two relatively arranged rotating seats 42 are provided at the center of the bottom of the partition 3. Rotating motors 43 are provided in the rotating seats 42. The rotating shafts of the rotating motors 43 are connected to the threaded rods 41. The center of the scraper 4 is provided with a threaded hole corresponding to the threaded rods 41. Through this structure, the scraper 4 can move to scrape off the sludge, so that the sludge can be effectively treated.

[0024] The water outlet 21 is arranged lower than the water inlet 11, and the height of the water outlet 21 is lower than the filter height of the partition 3, so as to prevent the unprecipitated solids from flowing back to the first filter tank, so that the sewage can be effectively filtered while ensuring the speed of sewage treatment.

[0025] The threaded rod 41 is extended to the bottom of the outer wall of the No. 1 filter tank 1 and the No. 2 filter tank 2, so as to cooperate with the sealing lifting plate 53 to seal the sewage outlet and isolate the sludge and sewage.

[0026] Working principle: when water enters, sewage rushes into the bottom of the No. 1 filter plate from the inclined plate. The rising water is filtered by the No. 1 filter plate, rises to the height of the partition filter screen, and flows into the No. 2 filter tank through the gap between the No. 2 filter plate and the partition. When the liquid level rises, it is filtered again by the No. 2 filter plate, so that the solid matter in the sewage is effectively treated. When the sedimentation tank is working, the sealing lifting plate is in an ascending state, and the sliding sealing plate is sealed to prevent water leakage. When it is necessary to discharge, the rotating motor drives the threaded rod to rotate, so that the scraper moves to the sewage outlet to scrape the sludge into the sewage tank. At this time, the sealing lifting plate descends and cooperates with the scraper to seal, separating the sludge from the water. The sliding sealing plate is opened by the hydraulic telescopic rod, and the sludge is discharged manually or by machine, so that the sedimentation tank is cleaned. Different filter tanks have different sediment amounts and different processing times. By setting two filter tanks, the sediment treatment process can be optimized.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
