DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. EMBODIMENT

[0021] Referring to Figures 1-4 The utility model provides a technical scheme: a kind of high-efficiency quick slurry pumping device of clay sedimentation tank, including sedimentation tank 1;Slurry pumping device further includes:

[0022] The cyclone slurry suction device 2 includes a fixed frame 20, an elbow pipe 23, a tapered pipe 25, and a connecting pipe 27. The elbow pipe 23 is fixedly installed at the bottom of the fixed frame 20. The tapered pipe 25 is fixedly installed at the upper part of the fixed frame 20. The connecting pipe 27 is threadedly fixedly installed at the end of the tapered pipe 25 away from the fixed frame 20. The connecting pipe 27 is fixedly connected with the negative pressure port of the external slurry pump.

[0023] The slurry disturbance device 3 includes an electric push rod 30, a sliding rod 31, connecting plates 32, and a disturbance block 33. The electric push rod 30 is fixedly installed at one side outside the sedimentation tank 1. The sliding rod 31 is slidingly installed inside the sedimentation tank 1, and both ends of the sliding rod 31 penetrate the inner wall of the sedimentation tank 1. The sliding rod 31 is fixedly installed on the two connecting plates 32. The disturbance block 33 is fixedly installed on the sliding rod 31 and located inside the sedimentation tank 1.

[0024] The fixed frame 20 is fixedly installed on the inner bottom wall of the sedimentation tank 1 by expansion bolts 21 and fastening nuts 22. A first flange plate 24 is fixedly installed on the elbow pipe 23. A second flange plate 26 is fixedly installed on the tapered pipe 25. The elbow pipe 23 and the tapered pipe 25 are fixedly installed on the fixed frame 20 by the first flange plate 24 and the second flange plate 26 using double-head bolt nuts 28. The piston rod end of the electric push rod 30 is fixedly connected with the connecting plate 32 at one side of the sliding rod 31. A sealing ring is installed at the hole where the inner wall of the sedimentation tank 1 slidingly cooperates with the sliding rod 31, and the sealing ring is fixedly installed on the inner wall of the sedimentation tank 1.

[0025] The working principle is as follows: after the sedimentation of the slurry in the sedimentation tank 1 is completed, the slurry pump is started. After the slurry pump works, negative pressure is generated in the connecting pipe 27 connected with the slurry pump. Since the connecting pipe 27 is tightly connected with the tapered pipe 25 and the elbow pipe 23, the negative pressure is transmitted to the opening of the elbow pipe 23 through the tapered pipe 25 and the elbow pipe 23. Under the action of the strong negative pressure, the slurry is sucked into the elbow pipe 23 and pumped into the tapered pipe 25 and the connecting pipe 27, and finally discharged by the sludge pump. When the sludge enters the elbow pipe 23, it will accelerate under the action of the arc of the curved section of the elbow pipe 23. The inclined inner wall of the tapered pipe 25 will also make the slurry flow in a spiral shape. The cyclone will disperse the slurry on the bottom plate and decompose the massive sludge into slurry with better fluidity, while avoiding stirring the hard sediment on the bottom layer.

[0026] If the mud in the tank has low water content and poor fluidity, or the mud is partially hardened, at this time the electric push rod 30 can be opened, the electric push rod 30 repeatedly pushes out and withdraws the piston rod when working, with the action of the piston rod of the electric push rod 30, the slide rod 31 drives the disturbing block 33 to continuously move back and forth in the sedimentation tank 1, the disturbing block 33 can disturb the mud and accelerate its flow, so as to improve the pumping efficiency.

[0027] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
