[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a quick-detachable silting device 4 is provided on the front end outer wall near the bottom of the purification treatment tank 1. The quick-detachable silting device 4 includes a metal closing frame 16, a fixed pressure plate 17, a metal sealing plate 20, a rubber sealing pad 21 and a silting port 22. The silting port 22 runs through the interior of the front end outer wall of the purification treatment tank 1 near the bottom. The metal closing frame 16 is welded to the outside of the front end opening of the silting port 22. The rubber sealing pad 21 is fixed to the rear end outer wall of the metal sealing plate 20, and the metal sealing plate 20 is plugged into the interior of the metal closing frame 16. At the same time, the rubber sealing pad 21 is attached to the front end outer wall of the purification treatment tank 1. Two fixed pressure plates 17 are provided, and the two fixed pressure plates 17 are symmetrically welded on the left and right sides of the center of the metal sealing plate 20. At the same time, the front end outer walls of the right half and the front end outer walls of the left half of the two fixed pressure plates 17 are both inclined.

[0026] Furthermore, the quick-detachable silting device 4 also includes a fixed pressure rod 18, a connecting block 19 and a metal rotating shaft 23, and the fixed pressure rod 18, the connecting block 19 and the metal rotating shaft 23 are respectively provided with two, the two connecting blocks 19 are symmetrically welded on the top outer wall of the metal closing frame 16, and the two metal rotating shafts 23 are respectively longitudinally inserted into the two connecting blocks 19, and the rear ends of the two metal rotating shafts 23 are welded with stoppers, the top ends of the two fixed pressure rods 18 are respectively connected to the front ends of the two metal rotating shafts 23 by welding, and the fixed pressure rod 18 can be rotated clockwise and counterclockwise through the metal rotating shaft 23, the rubber sealing pad 21 is made of soft rubber, and the thickness of the rubber sealing pad 21 is one-third of the thickness of the metal sealing plate 20, and the fixed When the pressure rod 18 contacts the outer wall of the front end of the fixed pressure plate 17, the rubber sealing pad 21 is in a squeezed state. When the purification tank 1 needs to be used to purify the sewage, the quick-detachable silting device 4 needs to be sealed to the outside of the silting port 22 to ensure that the inside of the sedimentation tank 11 is in a closed state, so that the water inside the sedimentation tank 11 can normally precipitate impurities. During operation, the two fixed pressure rods 18 need to be rotated outward through the metal shaft 23 so that the main parts of the two fixed pressure rods 18 are rotated to the outside of the metal sealing frame 16, and then the metal sealing plate 20 needs to be placed on the front side of the metal sealing frame 16, with the rubber sealing pad 21 facing downward to the metal sealing frame 16, and then the metal sealing plate 20 is directly 0 is inserted into the metal sealing frame 16, and then the left and right fixed pressure rods 18 need to be rotated clockwise and counterclockwise respectively. Taking the operation of the left fixed pressure rod 18 as an example, after the fixed pressure rod 18 is rotated clockwise, it will contact the fixed pressure plate 17 on the front end outer wall of the left side of the metal sealing plate 20, and the fixed pressure rod 18 at this time will contact the inclined surface of the outer wall of the right half of the fixed pressure plate 17. As the fixed pressure rod 18 continues to rotate clockwise, the inclined surface will slowly guide the fixed pressure rod 18 to the front end outer wall of the left half of the fixed pressure plate 17. Because the front end of the left half of the fixed pressure plate 17 is a plane, when the fixed pressure rod 18 is rotated to abut against the front end flat outer wall of the left half of the fixed pressure plate 17, it is affected by the thickness of the fixed pressure plate 17 itself. The action will push the metal sealing plate 20 backwards, so it will produce an squeezing effect on the rubber sealing gasket 21 attached to the front end outer wall of the purification treatment tank 1, so that the rubber sealing gasket 21 is squeezed and tightly pressed against the front end outer wall of the purification treatment tank 1, so that the dredging port 22 can be tightly sealed to avoid leakage. When it is necessary to dredge the inside of the sedimentation tank 11 through the dredging port 22, it is only necessary to rotate the two fixed pressure rods 18 so that the two fixed pressure rods 18 are respectively detached from the front ends of the two fixed pressure plates 17, thereby quickly unlocking the metal sealing plate 20 inside the metal closing frame 16, and then directly taking out the metal sealing plate 20, so that dredging work can be carried out through the dredging port 22 in the open state.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
