[0034] In order to make the content of the utility model easier to be clearly understood, the following further detailed description of the utility model is given according to specific embodiments in conjunction with the drawings.

[0035] As Figures 1 - 3 shown, a sludge receiving tank flushing device includes:

[0036] An installation platform 100, with a sludge receiving tank arranged inside the installation platform 100;

[0037] The grille is installed inside the sludge receiving tank. The grille is adapted to divide the sludge receiving tank into a sludge treatment chamber and a flushing transition chamber. The flushing transition chamber is provided with an opening communicating with the outside;

[0038] The flipping cover plate 200, one side of the flipping cover plate 200 is hinged to the installation platform 100, and a flipping connection bracket 210 is arranged on the side edge of the flipping cover plate 200;

[0039] Two driving members 300, the driving members 300 are installed on the installation platform 100, the driving ends of the driving members 300 are connected to the flipping connection bracket 210, and the driving members 300 are adapted to drive the flipping cover plate 200 to rotate around the side hinged to the installation platform 100 to close or open the opening of the flushing transition chamber;

[0040] Two flushing assemblies, the flushing assemblies are adapted to flush the grille when the flipping cover plate 200 opens the opening of the flushing transition chamber.

[0041] In this embodiment, as Figures 1 - 2 shown, the sludge in the sludge receiving tank flows from the flushing transition chamber to the sludge treatment chamber. The grille filters out large debris. After long-term use, sludge is likely to accumulate on the grille, affecting the filtration efficiency. To solve this problem, the grille needs to be cleaned. During cleaning, first start the driving member 300, drive the flipping cover plate 200 to open through the driving member 300, then start the flushing assembly. The water outlet of the flushing assembly faces the grille, and the grille is cleaned by the flushing water, which can effectively improve the efficiency and stability of sludge treatment. The grille is inclined and installed inside the sludge receiving tank, and the flushing assembly can also flush the flipping cover plate 200.

[0042] Specifically, as Figures 1 - 2 shown, the driving member 300 is a telescopic cylinder. One end of the telescopic cylinder is hinged to the installation platform 100, and the other end is hinged to the flipping connection bracket 210.

[0043] In this embodiment, as Figures 1 - 2 shown, when the grille needs to be cleaned, the piston rod of the telescopic cylinder extends or retracts, thereby driving the flipping connection bracket 210 to make the flipping cover plate 200 open or close around the hinge point. When opening, the flipping cover plate 200 exposes the grille, and the flushing assembly can spray high-pressure water flow on the grille for flushing and cleaning. After cleaning, the telescopic cylinder contracts, driving the flipping cover plate 200 to close, and the sludge and flushing wastewater are received in the sludge receiving tank. The two ends of the telescopic cylinder are hinged, avoiding the consumable loss of components such as ropes; in addition, the telescopic movement of the telescopic cylinder can be controlled by an electromagnetic valve to achieve automatic opening and closing, improving work efficiency.

[0044] Specifically, as Figure 3 shown, the flushing assembly can have the following structure:

[0045] The water inlet pipe 410, and the water inlet pipe 410 is connected to a water source;

[0046] The horizontal rotary seat 420, the horizontal rotary seat 420 is installed on the water inlet pipe 410, and the horizontal rotary seat is communicated with the water inlet pipe 410;

[0047] The vertical rotary branch pipe 430, the water inlet of the vertical rotary branch pipe 430 is sleeved on the water outlet of the horizontal rotary seat 420;

[0048] The flushing water outlet pipe 440, the flushing water outlet pipe 440 is rotatably installed on the water outlet of the vertical rotary branch pipe 430, and the flushing water outlet pipe 440 is adapted to vertically rotate around the vertical rotary branch pipe 430.

[0049] In this embodiment, as Figure 3 shown, the flushing water outlet pipe 440 can be freely adjusted on two rotation axes through the horizontal rotary seat 420 and the vertical rotary branch pipe 430, with a large spray angle range and a wide cleaning coverage area. During use, the flushing assembly can be a water cannon or a fire cannon.

[0058] In this embodiment, as Figure 3 shown, when it is necessary to fix the vertical jet angle of the flushing outlet pipe 440, the annular tightening hoop 510 can be locked by operating the tightening hoop adjusting member, so that the annular tightening hoop 510 tightly clamps the rotating connection joint of the vertical rotating branch pipe 430 and the flushing outlet pipe 440, making the flushing outlet pipe 440 unable to continue rotating around the vertical rotating branch pipe 430. When the jet angle needs to be adjusted, loosen the tightening hoop adjusting member, the annular tightening hoop 510 will loosen, and the flushing outlet pipe 440 can freely rotate vertically to the required angle, and then lock it again to fix the new jet angle. The tightening hoop adjusting member is a bolt-nut locking mechanism, including a through hole installed on the annular tightening hoop 510 and a matching bolt and nut.

In some embodiments, the movable operating handle 470 can also be installed on the flushing outlet pipe 440 to adjust the vertical jet angle of the nozzle, and at the same time, the entire vertical rotating branch pipe 430 can be rotated to adjust the horizontal jet direction. In addition, the handle end of the movable operating handle 470 can adopt an anti-slip texture to prevent slipping.

[0063] Specifically, as Figures 1 - 2 shown, there are two flushing assemblies, and one flushing assembly is provided on each side of the flipping cover plate 200.

[0064] In some embodiments, as Figures 1 - 2As shown, there can be two flip covers 200 arranged side by side. At this time, only three flushing assemblies can be provided, and the flushing assembly in the middle of the two flip covers 200 can be a common flushing assembly.
