DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0025] As Figures 1 to 6 shown, the embodiment provides a pump well separated type sewage lifting and depositing device, including a sedimentation tank 1, one side of the sedimentation tank 1 is provided with a sewage inlet, the other side of the sedimentation tank 1 is provided with a sewage outlet, and the area below the sewage outlet is a sedimentation area, and a solid waste collection frame is arranged outside the sewage outlet.

[0026] The sedimentation tank 1 includes the first tank body part 1.1 and the second tank body part 1.2 distributed in the up and down direction, the first tank body part 1.1 is a rectangular structure, and the second tank body part 1.2 is a conical structure. The bottom of the second tank body part 1.2 is connected with a mud pump 2, and the mud pump 2 is used to pump out the sludge in the sedimentation tank 1 after the sludge in the sedimentation tank 1 is deposited for a certain time, so as to realize the effect of sludge discharge.

[0027] The inside of the first pool body part 1.1 is provided with a reversible sealing plate 3, which is in a vertical state in the initial state, and can be switched to a horizontal state by turning over. The turning plate is provided with a grid-shaped channel, which has an open state and a closed state. When the channel is in the closed state, the sealing plate 3 separates the bottom sludge from the upper sewage of the sedimentation tank 1. The inside of the sedimentation tank 1 is provided with a power device 4, which is used to control the turning plate to switch from the vertical state to the horizontal state, and during the process of pumping sludge by the sludge pump 2, the power device 4 drives the sealing plate 3 to descend in the sedimentation tank 1 and press the sludge.

[0028] Specifically, the sealing plate 3 is in a vertical state in the initial state, so that the sludge can better settle at the bottom. When the power device 4 drives the sealing plate 3 to switch from the vertical state to the horizontal state, the channel remains in the open state.

[0029] In the initial stage of driving the sealing plate 3 to descend in the sedimentation tank 1 by the driving device, the channel remains in the open state, so that the sewage located between the sealing plate 3 and the sludge can move more smoothly to the upper side of the sealing plate 3 through the channel, reducing the disturbance of the sewage and sludge in the sedimentation tank 1, and preventing the settled sludge from being dispersed in the sewage again.

[0030] During the process of driving the sealing plate 3 to press the sludge by the driving device, the channel is in the closed state. At this time, the sealing plate 3 separates the sedimentation tank 1, reduces the amount of sewage brought out by the sludge pump 2 during the process of pumping sludge, and guarantees the sewage treatment effect. At the same time, the sealing plate 3 presses the sludge, which can improve the sludge discharge effect.

[0031] The top of the inside surface of the second pool body part 1.2 is provided with multiple rows of overflow holes 5 distributed vertically. Adjacent two rows of overflow holes 5 are arranged in a staggered distribution in the circumferential direction. By arranging the overflow holes 5, when the sealing plate 3 descends to the lowest position, the overflow holes 5 communicate the first pool body part 1.1 and the second pool body part 1.2, so that during the pumping process of the sludge pump 2, the sewage will flush the sludge on the inner side wall of the second pool body part 1.2 after passing through the overflow holes 5, improving the sludge discharge effect. At the same time, during the pumping process of the sludge pump 2, the overflow holes 5 reduce the negative pressure in the area below the sealing plate 3, improving the pumping efficiency of the sludge pump 2.

[0032] The sealing plate 3 includes a first plate body 3.1 and a second plate body 3.2, and the first plate body 3.1 and the second plate body 3.2 are respectively provided with first grid holes 3.3 and second grid holes 3.4 at equal intervals, and the first grid holes 3.3 and the second grid holes 3.4 are in a coincident state to form a channel. After the sealing plate 3 descends to a certain height, the first grid holes 3.3 and the second grid holes 3.4 are staggered by displacing the second plate body 3.2 relative to the first plate body 3.1, so that the channel is closed. Then, during the descending process of the sealing plate 3, the sludge is pressed, and the pumping action of the sludge pump 2 is improved, improving the sludge discharge effect.

[0033] The first plate 3.1 and the second plate 3.2 slide together to control the switching between the first grille holes 3.3 and the second grille holes 3.4 between an overlapping state and an interlaced state. Specifically, a sliding groove 15 is formed on the side of the first plate 3.1 facing the second plate 3.2. A slider 16 slides within the sliding groove 15 and is fixedly connected to the second plate 3.2.

[0034] The dimensions of the first plate 3.1 match the inner dimensions of the first tank portion 1.1, while the dimensions of the second plate 3.2 are smaller than those of the first plate 3.1. This arrangement ensures that when the sealing plate 3 is flipped to the horizontal position, the circumferential side surface of the first plate 3.1 contacts the inner wall surface of the first tank portion 1.1, achieving a separation effect.

[0035] A first slide bar 6 is fixedly provided in the middle position of the two opposite side surfaces of the first plate body 3.1, a second slide bar 7 fixedly provided on one side of the first slide bar 6, a third slide bar 8 is fixedly provided on the two opposite side surfaces of the second plate body 3.2, and the second slide bar 7 and the third slide bar 8 located on the same side of the closing plate 3 are respectively located on both sides of the first slide bar 6, and a first rod groove 9, a second rod groove 10 and a third rod groove 11 are respectively provided on the side wall of the first pool body part 1.1 for the displacement of the first slide bar 6, the second slide bar 7 and the third slide bar 8. During the process of flipping and lifting the closing plate 3, the first slide bar 6, the second slide bar 7 and the third slide bar 8 are respectively displaced in the first rod groove 9, the second rod groove 10 and the third rod groove 11, while being able to keep the first plate body 3.1 and the second plate body 3.2 in a stable state.

[0036] The first rod groove 9, the second rod groove 10 and the third rod groove 11 are respectively provided with an arc portion 12 for the first slide bar 6, the second slide bar 7 and the third slide bar 8 to perform circular motion following the flipping of the sealing plate 3, and a straight portion 13 for the first slide bar 6, the second slide bar 7 and the third slide bar 8 to perform lifting motion following the sealing plate 3, and an inclined portion 14 for driving the first slide bar 6 and the second slide bar 7 to shift laterally is provided between the arc portion 12 and the straight portion 13 of the first rod groove 9 and the second rod groove 10.

[0037] When the sealing plate 3 is flipped, the first slide bar 6, the second slide bar 7 and the third slide bar 8 slide in the corresponding arc part 12 respectively. During the descending process of the sealing plate 3, the third slide bar 8 is always displaced in the corresponding straight part 13, while the first slide bar 6 and the second slide bar 7 first pass through the inclined part 14 and then slide in the corresponding straight part 13 during the descending process.

[0038] The power unit 4 is a cylinder, the top of which is rotatably mounted on the inner wall of the first tank body portion 1.1, and the bottom of which is rotatably connected to the first plate body 3.1. When the sealing plate 3 is in the vertical position, the cylinder is tilted. The cylinder controls the flipping and lifting of the sealing plate 3 by extending and retracting.

[0039] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
