Description

Technical Field

[0001] This invention relates to the field of water pump technology, specifically to a mining underground water pump recycling device. Background Technology

[0002] In the heart of the Gobi Desert in Northwest my country, water scarcity has long been a core bottleneck restricting mining development. Water shortages not only directly constrain the stable release of mine capacity and the progress of expansion plans, but also affect the basic living conditions and well-being of employees. Furthermore, insufficient fire-fighting water and unstable production water supply pose multiple hidden dangers to safe production in mining areas. By focusing on the efficient development and recycling of groundwater resources, an innovative comprehensive groundwater utilization system has been created. This system utilizes previously underutilized underground drainage water and underground spring water as core water sources, through scientific storage and... By implementing graded treatment and precise allocation, the system achieves closed-loop utilization of water resources across all mining scenarios, establishing a new paradigm for the sustainable utilization of water resources in Gobi mining areas. Addressing the dispersed distribution and varying quality of underground drainage and inrush water, the system sets up distributed water collection facilities at each water source point and installs variable frequency submersible pumps to automatically adjust the pumping volume based on the water level. Drainage water is directly transported to industrial water tank groups, while inrush water with superior quality is directed to domestic water tank groups, achieving "source classification and on-demand delivery," completely changing the previous wasteful situation of "water flowing as it is extracted" in underground mines.

[0003] In existing technologies, when water pumps are used to transport water from storage tanks, the water source is often well drainage water, which inevitably contains solid impurities such as silt and rock fragments. Although the storage tanks are equipped with a sedimentation pretreatment process to remove some large particles, a certain amount of fine solid particles still remain in the pretreated water. When these remaining fine solid particles enter the pump along with the water, they will interact with critical flow components such as the pump impeller and sealing rings during long-term operation. Continuous friction and impact over a long period of time will cause impeller wear and affect the sealing performance of the sealing ring, which in turn will affect the normal operation of the water pump. Some existing water pumps have a filter device installed at the inlet to intercept impurities in order to reduce the entry of impurities into the pump body. However, during long-term use, solid impurities in the water will gradually adhere to and accumulate on the surface of the filter device, causing the filter device to become blocked. This will reduce the water flow rate of the water pump and increase the water inlet resistance, affecting the water pump's suction performance and normal delivery efficiency, which is not conducive to the stable operation of the water pump. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a mining underground water pump recycling device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mining underground water pump recycling device, comprising a pump body, a fixed pipe connected to one side of the bottom end of the pump body, a deceleration assembly provided on the inner wall of the end of the fixed pipe away from the pump body, the deceleration assembly including a connecting pipe, a filter assembly provided inside the fixed pipe, the filter assembly including a connecting pipe connected to the inner wall of the fixed pipe, the connecting pipe being inserted through the inner wall of the connecting pipe and connected to the connecting pipe, an inlet pipe sleeved on the outer wall of the end of the connecting pipe away from the connecting pipe, the end of the inlet pipe away from the connecting pipe being connected to a pipeline, and two sets of slots symmetrically opened on the inner wall of the connecting pipe, the slots being connected to the internal cavity of the fixed pipe.

[0006] Preferably, the outer wall of the connecting pipe near the water inlet pipe has multiple sets of water inlet holes, and the inner wall of the connecting pipe away from the water inlet pipe has two sets of guide plates symmetrically arranged, and the surface of the two sets of guide plates has multiple sets of protrusions.

[0007] Preferably, a retaining ring is provided at the contact position between the outer wall of the connecting pipe and the connecting pipe, and an air bladder is provided on the side surface of the retaining ring away from the connecting pipe. Pistons are symmetrically provided on the outer wall of the air bladder, and the pistons pass through the retaining ring.

[0008] Preferably, the outer wall of the water inlet pipe is symmetrically provided with two sets of sliders, one end of the connecting pipe is provided with two sets of sliding grooves that match the sliders, the inner wall of the connecting pipe is symmetrically provided with two sets of arc-shaped plates, and the end of the piston away from the airbag is in contact with the arc-shaped plate.

[0009] Preferably, the inner wall of the connecting pipe is provided with a filter screen, the filter screen is sleeved on the outer wall of the connecting pipe, and a rotating blade is connected to the center of the filter screen by a shaft. The rotating blade is located on the inner wall of the water inlet of the water pump body.

[0010] Preferably, the filter screen has two sets of cleaning brushes on the side away from the connecting pipe. A limiting ring is fixedly connected to the inner wall of the connecting pipe. Two sets of insert rods are symmetrically connected to the inner wall of the limiting ring. The insert rods extend to the inner wall of one end of the cleaning brush. A return spring connected to the cleaning brush is fixedly sleeved on the outer wall of the insert rod.

[0011] Preferably, one side surface of the filter screen is provided with multiple sets of abutments, and the end of the cleaning brush away from the insertion rod is fixedly connected to an inclined block. The abutments contact the inclined blocks during rotation, and the contact positions between the abutments and the inclined blocks are all provided with inclined surfaces.

[0012] Preferably, a limiting block is fixedly connected to the side surface of the cleaning brush away from the filter screen, and a fixing rod is connected to the side surface of the limiting ring away from the filter screen, and a limiting groove matching the limiting block is opened on the surface of the fixing rod.

[0013] In summary, the present invention has the following main beneficial effects: 1. This invention achieves decentralized water flow by opening multiple sets of water inlets on the connecting pipe, allowing water to flow into the connecting pipe simultaneously from multiple locations, thereby forming a balanced water flow convergence. This effectively counteracts the local impact caused by the influx of water, making the overall flow velocity and pressure more stable and avoiding uneven flow velocity and pressure fluctuations. At the same time, the guide plate guides the water flow, directing it to flow smoothly along a preset path. The protrusions on the surface of the guide plate further impede the water flow, slowing down the flow velocity and reducing the degree of water flow turbulence, thereby improving the stability of water delivery. It also effectively prevents settled silt and impurities from being stirred up and suspended again due to water flow turbulence, reducing the impact damage of silt and impurities on the internal components of the water pump body, and extending the service life of the water pump body to a certain extent, facilitating long-term use of the water pump body. 2. This invention effectively filters out sediment and impurities in the water by setting up a filter screen, preventing them from entering the pump body and causing wear on key components such as the impeller, thus extending the pump's service life. During water flow, the rotating blades drive the filter screen to rotate. As the filter screen rotates, the cleaning brush continuously contacts and cleans the surface. Simultaneously, the abutment blocks squeeze the inclined blocks, and the return spring drives the cleaning brush to perform continuous reciprocating translational motion, cleaning the filter screen surface. This effectively prevents the filter screen pores from being blocked by sediment and impurities, ensuring the long-term stability of the filter screen's filtration efficiency, reducing the frequency of manual disassembly and cleaning, lowering equipment maintenance costs, and improving the operating efficiency and stability of the pump body.

[0016] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0017] A mining underground water pump recycling device, such as Figure 1 - Figure 11 As shown, the system includes a water pump body 1. A fixed pipe 2 is connected to one side of the bottom end of the water pump body 1. A speed reduction assembly is provided on the inner wall of the end of the fixed pipe 2 away from the water pump body 1. The speed reduction assembly can effectively reduce the water flow velocity. The speed reduction assembly includes a connecting pipe 32. A filter assembly is provided inside the fixed pipe 2. The filter assembly can filter out mud and sand impurities in the water flow, preventing mud and sand impurities from entering the water pump body 1 and causing damage to its internal components. The filter assembly includes a connecting pipe 4 connected to the inner wall of the fixed pipe 2. 1. The connecting pipe 32 is inserted into the inner wall of the connecting pipe 41 and is connected to the connecting pipe 41. The outer wall of the end of the connecting pipe 32 away from the connecting pipe 41 is fitted with an inlet pipe 31. The end of the inlet pipe 31 away from the connecting pipe 32 is connected to the pipeline. Two sets of slots 411 are symmetrically opened on the inner wall of the connecting pipe 41, and the slots 411 are connected to the internal cavity of the fixed pipe 2. Through the setting of the slots 411, after the water is filtered, it can flow into the internal cavity of the fixed pipe 2 through the slots 411 and then into the water pump body 1 for transportation.

[0018] See Figure 3 and Figure 4It is known that multiple sets of water inlet holes 33 are opened on the outer wall of the end of the connecting pipe 32 near the water inlet pipe 31. The water inlet holes 33 allow water to flow in from multiple directions, offsetting the local impact of the water flow and making the flow velocity and pressure of the water inside the connecting pipe 32 more stable. Two sets of guide plates 37 are symmetrically arranged on the inner wall of the end of the connecting pipe 32 away from the water inlet pipe 31. The surfaces of the two sets of guide plates 37 are provided with multiple sets of protrusions. The guide plates 37 can guide the direction of water flow and slow down the water flow velocity to a certain extent. In conjunction with the protrusions, the water flow velocity can be further slowed down, effectively preventing the suspended sediment from becoming suspended. A retaining ring 34 is provided at the contact position between the outer wall of the connecting pipe 32 and the connecting pipe 41. The retaining ring 34 can be used to install the airbag 35 and limit the connection of the connecting pipe 32. The surface of the retaining ring 34 away from the connecting pipe 41 is provided with the airbag 35. The airbag 35 can seal the contact position between the connecting pipe 32 and the inner wall of the connecting pipe 41, so that the connecting pipe 32 and the inner wall of the connecting pipe 41 form a cavity, which facilitates the flow of filtered water out from the slot 411. Pistons 36 are symmetrically provided on the outer wall of the airbag 35, and the pistons 36 pass through the retaining ring 34.

[0019] See Figure 3 , Figure 4 , Figure 5 , Figure 9 It is known that two sets of sliders are symmetrically arranged on the outer wall of the water inlet pipe 31, and two sets of sliding grooves matching the sliders are opened at one end of the connecting pipe 41. The sliders are snapped into the inner wall of the sliding grooves to connect the water inlet pipe 31 and the connecting pipe 41. With the help of bolts, the water inlet pipe 31 and the connecting pipe 41 can be further fixed. Two sets of arc plates are symmetrically arranged on the inner wall of the connecting pipe 41. The end of the piston 36 away from the airbag 35 contacts the arc plate. When the water inlet pipe 31 and the connecting pipe 41 are connected, the arc plate just squeezes the piston 36. At this time, the gas inside the piston 36 enters the airbag 35, causing the airbag 35 to expand, thereby improving the sealing effect of the airbag 35.

[0020] See Figure 5 - Figure 7 It is known that a filter screen 42 is provided on the inner wall of the connecting pipe 41. The filter screen 42 is sleeved on the outer wall of the connecting pipe 32. The filter screen 42 can filter the mud and sand impurities in the water flow, preventing the mud and sand impurities from entering the water pump body 1, thereby extending the service life of the water pump body 1. A rotating blade 43 is connected to the center of the filter screen 42 by a shaft. The rotating blade 43 is located on the inner wall of the water inlet of the water pump body 1. When the water flows into the water pump body 1 through the fixed pipe 2, the water flow can drive the rotating blade 43 to rotate. The rotating blade 43 can synchronously drive the filter screen 42 to rotate, preventing the filter screen 42 from being partially blocked and affecting the filtration effect of the filter screen 42.

[0021] See Figure 8 and Figure 11It is known that two sets of cleaning brushes 45 are provided on the surface of the filter screen 42 away from the connecting pipe 32. The cleaning brushes 45 can clean the surface of the filter screen 42 to prevent the filter holes from clogging. A limiting ring 44 is fixedly connected to the inner wall of the connecting pipe 41. Two sets of insert rods 441 are symmetrically connected to the inner wall of the limiting ring 44. The insert rods 441 extend to the inner wall of one end of the cleaning brush 45. The cleaning brush 45 can move back and forth on the outer wall of the insert rods 441. A return spring connected to the cleaning brush 45 is fixedly sleeved on the outer wall of the insert rods 441. The elastic force of the return spring can drive the cleaning brush 45 to return to its original position.

[0022] See Figure 10 and Figure 11 It can be seen that multiple sets of abutments 421 are provided on one side surface of the filter screen 42, and an inclined block 451 is fixedly connected to the end of the cleaning brush 45 away from the insertion rod 441. The abutments 421 contact the inclined block 451 during rotation, and the contact positions of the abutments 421 and the inclined block 451 are all provided with inclined surfaces. When the filter screen 42 rotates, the abutments 421 continuously squeeze the inclined block 451, thereby pushing the cleaning brush 45 to move back and forth in parallel, which to a certain extent improves the cleaning range and cleaning effect of the cleaning brush 45.

[0023] See Figure 11 It is known that a limiting block is fixedly connected to the side surface of the cleaning brush 45 away from the filter screen 42, and a fixed rod is connected to the side surface of the limiting ring 44 away from the filter screen 42. The surface of the fixed rod is provided with a limiting groove that matches the limiting block. The cleaning brush 45 can be limited by the setting of the limiting block and the limiting groove, so as to facilitate the parallel reciprocating movement of the cleaning brush 45 to clean the surface of the filter screen 42.

[0024] The working principle of this invention is as follows: When water is transported through the water pump body 1, the inlet of the water inlet pipe 31 is connected to the tank group. The water inside the tank group enters the water inlet pipe 31 through the inlet. The water is dispersed through multiple sets of water inlet holes 33, which allows the water to enter the connecting pipe 32 from multiple positions simultaneously, thereby offsetting the local impact of the water flow and making the overall flow velocity and pressure of the water inside the connecting pipe 32 tend to be stable. After the water enters the cavity inside the connecting pipe 32, the water flow is guided by the guide plate 37. The multiple sets of protrusions on the surface of the guide plate 37 slow down the water flow velocity, thereby reducing the degree of water flow turbulence. This can effectively prevent the settled silt from being rolled up again and becoming suspended to a certain extent. After the water flows through the connecting pipe 32, it enters the inside of the connecting pipe 41. Since the inner wall of the connecting pipe 41 is equipped with a filter screen 42, the filter screen 42 can filter out the mud and sand impurities in the water, thereby effectively preventing the mud and sand impurities in the water from causing wear to the impeller inside the water pump body 1, thus extending the service life of the water pump body 1 to a certain extent. After the water flows through the filter screen 42, it enters the pre-set cavity inside the connecting pipe 41, and then the filtered water flows into the fixed pipe 2 through the slot 411, and then flows into the water pump body 1, and the water is transported under the action of the water pump body 1. When water flows into the pump body 1 through the fixed pipe 2, it drives the rotating blade 43 to rotate. When the rotating blade 43 rotates, it drives the filter screen 42 to rotate synchronously through the shaft. Since the cleaning brush 45 is in contact with the surface of the filter screen 42, the filter screen 42 can be cleaned by the cleaning brush 45 during the rotation process, so as to avoid the filter holes of the filter screen 42 being blocked by mud and sand impurities after long-term use. When the filter screen 42 rotates, it synchronously drives the abutment block 421 to rotate. During the rotation, the abutment block 421 exerts a force on the inclined block 451, and pushes the cleaning brush 45 to move through the inclined block 451. When the abutment block 421 rotates and disengages from the inclined block 451, the pressure on the inclined block 451 is released. At this time, the cleaning brush 45 is reset under the elastic action of the return spring. Thus, during the rotation of the filter screen 42, the cleaning brush 45 can be driven to achieve continuous reciprocating translational motion, which can thoroughly clean the surface of the filter screen 42, thereby improving the cleaning effect of the cleaning brush 45.
