Concrete tends to accumulate in elbows and valves, leading to a high blockage rate. Furthermore, the hardening of residual concrete can exacerbate pump wear, shortening its service life and increasing maintenance costs. Therefore, a self-cleaning concrete pump device was designed.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] A self-cleaning concrete conveying pump device includes a concrete conveying pump 1, a water supply pump group 2, an air supply pump group 3, a concrete suction pipeline 4, a concrete discharge pipeline 5, a water supply pipeline 6, and an air supply pipeline 7. The concrete conveying pump 1, the water supply pump group 2, and the air supply pump group 3 are arranged in an orderly manner. The concrete suction pipeline 4 and the concrete discharge pipeline 5 are respectively connected to the two ends of the concrete conveying pump 1. The water supply pipeline 6 connects the concrete suction pipeline 4 and the water supply pump group 2. The air supply pipeline 7 connects the concrete suction pipeline 4 and the air supply pump group 3.

[0014] Both the concrete suction pipeline 4 and the concrete discharge pipeline 5 are equipped with three-way valves 8 in the middle section. The bottom side of the three-way valve 8 in the middle section of the concrete suction pipeline 4 is connected to an inlet pipe 9. The bottom side of the three-way valve 8 in the middle section of the concrete discharge pipeline 5 is connected to a discharge pipe 10. The water supply pipeline 6 and the gas supply pipeline 7 are arranged and connected to the inlet pipe 9, and both the water supply pipeline 6 and the gas supply pipeline 7 are connected to a single-control valve 11. The other side of the water supply pump set 2 is connected to a suction pipe 12.

[0015] The air supply pump assembly 3 consists of an air inlet 13, an air inlet filter material 14, a compressed air pump 15, an air pump exhaust pipe 16, a single-control valve 11, an air storage tank 17, a straight-opening pipeline 18, a straight-opening valve 19, a jogging pipeline 20, and a jogging valve 21. The air inlet 13 is connected to the air inlet side of the compressed air pump 15, and the air inlet filter material 14 is disposed inside the air inlet 13. The air pump exhaust pipe 16 is connected to the other side of the compressed air pump 15. The air storage tank 17 is connected to the end of the air pump exhaust pipe 16. The single-control valve 11 is connected to the air pump exhaust pipe 16. The straight-opening pipeline 18 and the jogging pipeline 20 are connected in parallel to the end of the air storage tank 17, and the straight-opening valve 19 and the jogging valve 21 are correspondingly connected to the straight-opening pipeline 18 and the jogging pipeline 20. The ends of the straight-opening pipeline 18 and the jogging pipeline 20 are connected in parallel to the beginning of the air supply pipeline 7.

[0016] The working principle of this utility model: The use of this mechanism is mainly divided into two working processes.

[0017] The first process is to clean the concrete pump 1 body. When cleaning the concrete pump 1, the three-way valve 8 on the concrete suction pipeline 4 and the concrete discharge pipeline 5 needs to be closed, so that the cleaning route is from the inlet pipe 9, the concrete suction pipeline 4, the concrete pump 1, the concrete discharge pipeline 5, to the discharge pipe 10. This isolates the concrete supply pipeline and the concrete delivery pipeline connected before and after the concrete pump 1, so that only the concrete pump is cleaned. During this process, the water supply pump group 2 and the air supply pump group 3 supply water and air respectively to clean the inside of the concrete pump 1.

[0018] The second process involves cleaning the concrete pump 1 itself and the concrete delivery pipeline connected to the concrete discharge pipeline 5. This process requires closing the three-way valve on the concrete suction pipeline 4 and opening the three-way valve 8 on the concrete discharge pipeline 5, ensuring that the cleaning route is from the inlet pipe 9, through the concrete suction pipeline 4, to the concrete pump 1, through the concrete discharge pipeline 5, and back to the concrete delivery pipeline. This allows the water and air supplied by the water supply pump group 2 and the air supply pump group 3 to be used for cleaning the concrete pump 1 and the concrete delivery pipeline connected to the concrete discharge pipeline 5.

[0019] The above two processes are divided into water cleaning and air cleaning. Water cleaning involves opening the single-control valve 11 on the water supply line 6 and closing the single-control valve 11 on the air supply line 7. This prevents water from flowing into the air supply pump unit 3 and causing damage. The water flows along the cleaning path. Air cleaning involves opening the single-control valve 11 on the air supply line 7 and closing the single-control valve 11 on the water supply line 6, blowing the water remaining after water cleaning out of the cleaning path. Alternatively, a water-air mixture can be used for cleaning. This process requires ensuring that the pressure of the air supply pump unit 3 is greater than the pressure of the water supply pump unit 2, allowing water to flow in the cleaning direction and reducing the impact on the normal operation of the cleaning equipment.

[0020] In addition, during the regas cleaning process, the air pump unit 3 uses two air outlet lines: a direct-opening line 18 and a jogging line 20. In this process, the compressed air pump 15 stores gas inside the air storage tank 17. The stored gas can be controlled by the jogging valve 21 and the direct-opening valve 19 respectively. When the direct-opening valve 19 is open and the jogging valve 21 is closed, air can be continuously supplied to the cleaning line for normal cleaning. When a blockage is encountered, the jogging valve 21 can be opened and the direct-opening valve 19 can be closed, which can achieve high-pressure impact cleaning of the line in clusters. Combined with water cleaning, it can be used to clear concrete blocks, unclog blocked pipes, etc.

[0021] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
