Abstract
Description
Technical Field
[0001] This utility model relates to the field of pump bodies, and in particular to a modular combined pump structure. Background Technology
[0002] Gravel pumps, also known as slurry pumps, are primarily used for the continuous transport of highly abrasive materials whose particles are too large for conventional slurry pumps to handle. They are suitable for applications such as mud transport, dredging, sand and gravel suction, river dredging, and slag transport in mining and metal smelting.
[0003] Existing slurry pumps directly extract and discharge slurry to another area. The solids and silt contained in the slurry are also discarded. Moreover, during discharge, they tend to adhere to the inside of the pump body, which can easily lead to resource waste and environmental pollution.
[0004] Therefore, it is necessary to propose a modular combined pump structure to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a modular combined pump structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular combined pump structure, including a slurry inlet seat, a slurry discharge seat on one side of the slurry inlet seat, and two slurry discharge ports connected to the bottom end of the slurry discharge seat. A first drainage cylinder and a second drainage cylinder are respectively provided at the bottom end of the two drainage ports, and multiple water holes are opened on the outer side of the first drainage cylinder and the second drainage cylinder.
[0007] Two rotating blades are fitted on the outer ring of the rotating shaft. The two rotating blades are respectively rotatably disposed inside the first drainage cylinder and the second drainage cylinder. Filter bags are installed at the bottom of the first drainage cylinder and the second drainage cylinder. Both rotating blades are elastic. The filter bags are connected to the bottom of the corresponding first drainage cylinder and the second drainage cylinder.
[0008] Preferably, each of the plurality of water holes is provided with a filter screen, and a rotating shaft is rotatably provided between the first drain cylinder and the second drain cylinder, with one end of the rotating shaft extending out of the first drain cylinder and the other end of the rotating shaft extending out of the second drain cylinder.
[0009] Preferably, both the first and second drainage cylinders are provided with a base plate at their bottom ends, and a through groove is provided at the bottom of the base plate, with a filter screen installed in the through groove.
[0010] Preferably, both the slurry inlet seat and the slurry outlet seat are provided with an inner cavity. A rotating shaft is rotatably provided between the slurry inlet seat and the slurry outlet seat. A shaft retainer is provided on the side of the slurry inlet seat and the slurry outlet seat that is far apart from each other. A second turntable is provided on the outer ring of the rotating shaft near the slurry inlet seat. A first turntable is provided on the outer ring of the rotating shaft near the slurry outlet seat. A vortex blade is provided between the first turntable and the second turntable. The vortex blade is sleeved on the outer ring of the rotating shaft. An annular discharge port is provided on the opposite side of the first turntable and the second turntable. An auxiliary port is provided on one side of the annular discharge port.
[0011] Preferably, the outer side of the vortex blade is provided with a protective shell, and the top of the slurry inlet seat is provided with two inlet ports.
[0012] Preferably, the two ends of the rotating shaft are respectively located inside the two shaft retainers, and multiple connecting rods are provided between the two sides of the slurry inlet seat and the slurry outlet seat.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. In this utility model, the slurry output by centrifugation is input into the interior of the first and second drainage cylinders through the slurry discharge port. The impacting water flow will drive the rotating blades to rotate. The rotating blades will sweep the slurry into the water holes on the outside of the first and second drainage cylinders. The water is discharged through the filter screen, leaving sand and solids. In addition, the filter screens set at the bottom of the first and second drainage cylinders can also increase the water discharge. Finally, the protective cylinder can collect the sand.
[0015] 2. In the actual operation of this utility model, the sand and solids will fall into the interior of the filter bag by gravity, and excess water can be discharged from the gaps in the filter bag. As the blades continue to rotate, they will squeeze the sand accumulated inside the filter bag, thereby squeezing out the water in the sand. If the water flow is large, the water source can be discharged from the water holes of the first and second drain cylinders to avoid clogging.
[0016] 3. The filter bag and the corresponding first and second drainage cylinders are detachably connected at their bottom ends, and the first and second drainage cylinders are connected to the corresponding slurry discharge ports via flanges. They can be installed or disassembled as needed to achieve modular assembly. Attached Figure Description
