Description

Technical Field

[0001] The invention relates to the technical field of paste delivery, and in particular to a capsule-type pipeline paste pump. Background Art

[0002] Due to the national environmental protection policy, industrial solid waste is not allowed to be piled up on the ground, so most of the industrial solid waste, especially tailings and coal gangue, will be filled underground. And underground filling must be filled with paste and paste-like filling, which requires a paste pump. In the past, the pumps used for paste transportation were basically reciprocating pumps, which used a push method to transport the paste.

[0003] Paste delivery pumps in the prior art are often connected in the form of crankshafts, connecting rods, and plungers to push the paste to move, which is not suitable for paste movement and is prone to safety failures. In addition, the feeding and discharge of existing plunger-type reciprocating pumps must pass through a right-angle check valve, which has a large feeding resistance and is prone to insufficient feeding. Finally, once the paste is added with cement to make it more viscous or when the paste is made on the ground, the paste cannot be delivered by the existing paste delivery pump.

[0037] The working principle of the capsule pipeline paste pump in the present invention is: taking paste or paste-like as an example, the deep cone thickener 1 can concentrate the slurry to a weight concentration of more than 70%. By utilizing the height of the deep cone thickener 1 (generally about 20m high) and the slumping performance of the paste's own weight, its flow rate can completely fill the capsule pipeline device 4.

[0038] During operation, the deep cone thickener 1 is filled with paste or paste-like slurry, and the microcomputer 9 controls to open the three-piece slurry valve 16 below the deep cone thickener 1 and the straight-through slurry valve 3 and the return water valve at the inlet of the capsule-type pipeline device 4. The paste or paste-like material in the deep cone thickener 1 can fill the capsule of the capsule-type pipeline device 4 unimpeded within a fixed time by its own weight and the potential energy of the height, and the clean water outside the capsule flows back to the clean water tank 7 through the return water valve. At this time, the straight-through slurry valve 3 at the outlet of the capsule-type pipeline device 4 is closed, and this process is the feeding process.

[0039] When the microcomputer 9 controls the straight-through slurry valve 3 at the inlet of the capsule-type pipeline device 4 to be closed and the straight-through slurry valve 3 at the outlet to be opened, the return water valve is closed and the inlet water valve is opened, the high-pressure clean water output by the clean water pump 6 enters the water tank through the inlet water valve, and then enters the outside of the capsule through the numerous holes on the tank body in the water tank, squeezes the paste slurry in the capsule, and flows to the storage location through the straight-through slurry valve 3 at the outlet. This process is the discharge process.

[0040] The diameter of the numerous holes in this embodiment does not exceed 10 mm, and the total area of ​​the numerous holes is equivalent to twice the cross-sectional area of ​​the water pipe. The pipeline paste pump uses the clean water pump 6 as the power source, and uses high-pressure clean water to squeeze the paste in the capsule to flow outward. It is safer and more suitable for paste movement than the traditional crankshaft, connecting rod, and plunger form to promote the movement of the paste, and is less prone to safety failures.

[0041] It should be noted that one paste pump has two or three capsule-type pipe devices 4, which move at an angle of 180° or 120°, and the input and output of paste are both in a continuous state. All actions are automatically controlled by the microcomputer 9, the valve actions are all instructed by the microcomputer 9 and driven by the hydraulic station 8, and the data collected by the pressure sensor 11, flow meter 12, bidirectional flow meter 10, etc. are all analyzed by the microcomputer 9 for the operation status, and the operation status is automatically adjusted.

[0042] It is worth mentioning that the capsule of the capsule-type pipeline paste pump must be filled with paste for each cycle, and each time the capsule is squeezed and deformed during the discharge process, only one-quarter of the volume of the paste in the capsule is discharged.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
