Description

Technical Field

[0001] The invention belongs to the technical field of emulsion pumps, in particular to an intelligent emulsion pump station with multiple pumps in a group. Background Art

[0002] In the fully mechanized mining working faces of modern large and medium-sized coal mines, a large number of hydraulic supports are used to support the tunnels. These hydraulic supports require emulsion pump stations to provide power to achieve actions such as pushing scraper conveyors, moving frames, adjusting frames, protecting walls, preventing falling, and preventing slipping. With the development of coal mining technology, the number of hydraulic supports continues to increase, and the flow and pressure requirements for emulsion pump stations are also getting higher and higher.

[0003] A Chinese invention patent publication number CN119280927 discloses an emulsion pump station with an energy-saving mechanism, including a base, a plurality of support frames are fixedly connected to the upper surface of the base, a motor, a pump station unit and a box are fixedly connected to the upper surface of the support frames, the top of the box is fixedly connected to a box cover, two first chutes are provided on the inner walls of both sides of the box, a slider is movably connected between the corresponding two first chutes, a scraper is fixedly connected between the two sliders, a wedge-shaped block is fixedly connected to the bottom of both ends of the scraper, two filter racks are fixedly connected to the inside of the box, and the scraper is in contact with the filter rack, and a second chute and a square port connected thereto are provided at the bottom of the box. The present invention can not only keep the raw material liquid entering the pump station unit clean, but also automatically discharge the cleaned impurities, and can also facilitate the collection of tools by pulling out the collection box.

[0004] However, the above technologies often have the following defects: However, the working conditions underground in coal mines are complex and changeable, and the load is constantly changing during the operation of the equipment, which makes the flow and pressure of the emulsion pump station prone to fluctuations. Unstable flow will delay the response of the hydraulic support. This instability will not only affect the working performance of equipment such as the hydraulic support, but also reduce the reliability and production efficiency of the equipment operation.

[0011] A sleeve is sleeved on the middle extension end of the diversion bottom end, and a flange portion is provided in the middle of the outer arc surface of the sleeve. The lower surface of the flange portion is placed on the top of the protruding end, and a spring is fixedly installed between the flange portion and the protruding end. A float is fitted and connected to the upper surface of the protruding end, and the outer arc surface of the float is fixedly installed on one end of the spring.

[0012] The ejection assembly comprises a cover body movably abutting against the inner arc surface of the liquid inlet tube body, the outer arc surface of the cover body is provided with a shoulder portion, and a docking groove B is provided between the cover body and the shoulder portion.

[0013] The top plug-in end of the liquid inlet tube body is movably connected to the inner wall of the docking groove B, the upper surface of the cover body is provided with a groove, the top groove of the cover body is provided with an internal thread, and the upper surface of the cover body is threadedly connected with a compression kit.

[0014] The interior of the compression kit is a structure that is wide at the top and narrow at the bottom. An inner sleeve body is provided in the middle of the inner arc surface of the cover body, and one end of the inner sleeve body passes through the bottom extension end of the diversion bottom end. The inner arc surface of the compression kit passes through and is fixedly connected with a pipe A, and one end of the pipe A extends to the interior of the inner sleeve body.

[0015] A rear cover is fixedly mounted on the back of the liquid pump body, a through hole is opened in the middle of the back of the rear cover, a stopper circular plate is abutted on the curved surface of the top of the confluence sleeve, and an outer convex tooth is arranged on the top of the outer arc surface of the stopper circular plate.

[0016] A mating circular plate is movably clamped on one side of the stop circular plate, and an inner concave tooth is provided on the edge of one surface of the mating circular plate.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. As the liquid inlet pipe body is pushed by the rear piston, the relative position change of the guide assembly and the sleeve causes the cavity volume of the liquid through the sleeve to change dynamically. The change in volume and the reciprocating motion of the rear piston cause the sleeve to displace axially under the action of pressure. At this time, the flange of the outer arc surface of the sleeve converts the pressure into squeezing the spring. The spring accumulates elastic potential energy during the compression process. When the pressure decreases slightly, it quickly releases energy to provide a continuous and stable negative pressure thrust for the emulsified oil inside the liquid through the sleeve. This negative pressure thrust cooperates with the positive pressure input at the front end to form a stable pressure gradient, ensuring that the emulsified oil can flow at a constant flow rate and pressure.

[0020] 2. The water flow direction is ensured by the diameter and length of the inner sleeve body inside the ejector assembly. When the water reaches the bottom of the inner sleeve body, because it is inserted into the extension end of the diversion bottom, and the opening design at the bottom of the extension end causes the water to flow into the liquid inlet body. The injection of water changes the balance of the fluid, and the water and the emulsified oil come into contact instantly. The two blend with each other in the liquid inlet body, and the emulsified oil is broken into countless tiny oil droplets by the impact force of the water flow. In this process, the kinetic energy of the water flow is converted into hybrid power. Under this action, the contact area between the emulsified oil droplets and the water flow is greatly increased, which promotes the full fusion between the two, increases the contact area between the oil droplets and water, and promotes the adsorption of the emulsifier at the oil-water interface, thereby improving the stability and uniformity of the emulsion.

[0021] 3. Through the ejection component, guide component and piston in the multi-pump intelligent emulsion pump station, ejection can achieve the reasonable distribution and flow coordination of emulsion between the pumps, avoiding problems such as uneven flow and pressure fluctuation. In addition, ejection can also reduce the energy consumption of the system to a certain extent, improve the energy utilization efficiency of the pump station, make the operation of the pump station more stable and reliable, and meet the high requirements under complex working conditions such as coal mine comprehensive mining working face.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, the embodiment of the present invention includes a motor 1, a coupling 101 is installed at the delivery end on the front side of the motor 1, a liquid pump body 2 is fixedly installed on the outer arc surface of the motor 1 through the crankshaft of the coupling 101, a solenoid valve 3 is penetrated and connected to the front side of the liquid pump body 2 near the front side of the motor 1, and a guide component 4 is movably sleeved on the inner arc surface of the liquid pump body 2. The guide component 4 includes a converging sleeve 41 sleeved in the inner arc surface of the liquid pump body 2, and a hook is provided on the top of the outer arc surface of the converging sleeve 41. The hook at the top of the converging sleeve 41 is clamped on the liquid pump body 2. On the back end surface, the lower surface of the concave end 42 is provided with a concave end 42, and one end of the concave end 42 is provided with a column cavity end 43. The converging sleeve 41 is connected to the solenoid valve 3 by means of the column cavity end 43. The inner arc surface of the converging sleeve 41 is movably abutted against the liquid inlet tube body 44, and the bottom of the outer arc surface of the liquid inlet tube body 44 is provided with a supporting rib end 45. The outer arc surface of the supporting rib end 45 is movably abutted against the inner arc surface of the converging sleeve 41, and a docking groove A46 is provided between the supporting rib end 45 and the liquid inlet tube body 44, and the inner arc surface of the docking groove A46 is movably clamped with a liquid sleeve 47.

[0041] The motor 1 efficiently transmits the rotational power to the crankshaft of the liquid pump body 2 through the coupling 101, and the crankshaft rotates continuously at a stable speed, driving the entire liquid pump system into a circulating working state. At this time, the confluence sleeve 41 becomes a fluid hub, and the column cavity end 43 arranged on its end side provides sufficient buffering and transition space for the convergence of emulsified oil by virtue of the long-distance linear channel design, effectively reducing the turbulence of the fluid during the convergence process.

[0042] The converging sleeve 41 is integrally formed with the liquid pump body 2 in a bent structure, and the concave end 42 at the inner arc surface thereof is in a conical structure, which fits with the conical structure of the bottom surface of the liquid passage sleeve 47, thereby forming a fluid guide. When the emulsified oil flows through here, it is constrained and guided by the conical structure and gradually concentrates toward the central axis along the inner wall, thereby realizing the initial convergence and directional guide of the fluid.

[0043] The liquid inlet tube 44 serves as an important channel for the emulsified oil to enter the system. The docking groove A46 arranged on its surface is embedded with the liquid sleeve 47. As the liquid inlet tube 44 is displaced under the push of the rear end piston 10, the relative position change of the two causes the cavity volume of the liquid sleeve 47 to change dynamically. The change in volume and the reciprocating motion of the rear end piston 10 form a "breathing" fluid regulation mechanism. When the piston 10 moves forward, the internal pressure of the liquid inlet tube 44 increases sharply, and the emulsified oil is driven by the strong pressure difference and rushes into the liquid sleeve 47 at high speed from the liquid inlet hole 491 at the top of the diversion bottom 49.

[0044] It is worth mentioning that the extension end of the lower surface of the diverter bottom 49 is completely isolated from the emulsified oil, which effectively avoids fluid leakage. The pressure generated by the liquid inlet pipe body 44 in the sleeve 5 connected to the periphery of the extension end is transmitted to the sleeve 5 through the diverter bottom 49. The sleeve 5 undergoes axial displacement under the action of pressure. At this time, the flange portion 51 on the outer arc surface of the sleeve 5 converts the pressure into squeezing of the spring 52. The spring 52 accumulates elastic potential energy during the compression process. When the pressure is slightly weakened, it quickly releases energy to provide a continuous and stable negative pressure thrust for the emulsified oil inside the liquid sleeve 47. This negative pressure thrust cooperates with the positive pressure input at the front end to form a stable pressure gradient, ensuring that the emulsified oil can be delivered to the column cavity end 43 inside the liquid pump body 2 at a constant flow rate and pressure.

[0045] like Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the ejection assembly 6 includes a cover body 61 that is movably abutted against the inner arc surface of the liquid inlet tube body 44, the outer arc surface of the cover body 61 is provided with a shoulder portion 62, a docking groove B63 is provided between the cover body 61 and the shoulder portion 62, the top plug-in end 410 of the liquid inlet tube body 44 is movably connected to the inner wall of the docking groove B63, the upper surface of the cover body 61 is provided with a groove, the top groove of the cover body 61 is provided with an internal thread, the upper surface of the cover body 61 is threadedly connected with a compression kit 65, the interior of the compression kit 65 is a structure of wide at the top and narrow at the bottom, an inner sleeve body 66 is provided in the middle of the inner arc surface of the cover body 61, one end of the inner sleeve body 66 penetrates into the bottom extension end of the diversion bottom end 49, the inner arc surface of the compression kit 65 penetrates and is fixedly connected with a pipeline A7, one end of the pipeline A7 extends to the inner sleeve body Inside 66, a rear cover 8 is fixedly installed on the back of the liquid pump body 2, a through hole is opened in the middle of the back of the rear cover 8, the bent surface on the top of the confluence sleeve 41 abuts against a stop circular plate 9, an outer convex tooth 91 is provided on the top of the outer arc surface of the stop circular plate 9, a mating circular plate 92 is movably clamped on one side of the stop circular plate 9, and an inner concave tooth 93 is provided on the edge of one side surface of the mating circular plate 92, a piston 10 is slidably connected to the inner arc surface of the rear cover 8 close to the mating circular plate 92, and a transmission shaft 11 is movably connected to the back of the piston 10 through a rotating shaft, one end of the transmission shaft 11 passes through the through hole of the rear cover 8, the outer arc surface of the liquid inlet pipe body 44 is penetrated and connected with a pipe B12, one end of the pipe B12 passes through the outside of the rear cover 8, and the liquid inlet pipe body 44 and the rear cover 8 are both hollow through structures.

[0046] However, in the rear cover 8, the top of the liquid inlet tube body 44 is sleeved with the upper cover body 61, and the cover body 61 is sleeved on the top of the liquid inlet tube body 44. The inner sleeve body 66 nested inside it forms a dual-track parallel independent channel with the liquid inlet tube body 44, providing a non-interfering path for the transportation of different media. The compression kit 65 on the top of the cover body 61 uses rubber to form a seal with the top of the liquid inlet tube body 44. When the external water source enters the compression kit 65 through the pipe A7, the water flow rushes down at high speed along the inner wall of the inner sleeve body 66 under pressure. The diameter and length of the inner sleeve body 66 ensure the flow direction of the water. When the water flow reaches the bottom of the inner sleeve body 66, because it is inserted into the extension end of the diversion bottom end 49, and the opening design at the bottom of the extension end, the water flow flows into the liquid inlet tube body 44.

[0047] At this moment, the emulsified oil in the liquid inlet pipe body 44 is in a flowing state, and a stable fluid trajectory is formed under the synergistic effect of the confluence sleeve 41 and the liquid through sleeve 47. The injection of water changes the balance of the fluid, and the water flow and the emulsified oil come into contact instantly. The two blend with each other in the liquid inlet pipe body 44, and the emulsified oil is broken into countless tiny oil droplets by the impact force of the water flow. In this process, the kinetic energy of the water flow is converted into hybrid power, and the emulsified oil and water are automatically introduced into the confluence sleeve 41 for mixing under the push pressure inside the cavity.

[0048] Due to the conical structure of the bottom surface of the liquid-through sleeve 47, when the water flows downward and contacts the inside of the liquid-through sleeve 47, it will concentrate and flow toward the lowest point. The conical structure also causes the fluid to continuously change direction during the flow, forming a vortex motion. Under the action of the vortex, the contact area between the emulsified oil droplets and the water flow is greatly increased, thereby promoting the full fusion between the two.

[0049] like Figures 1 to 9 As shown, the bottom of the outer arc surface of the liquid-through sleeve 47 is a conical structure, and the conical structure of the bottom of the liquid-through sleeve 47 is adapted to the inner arc surface of the concave end 42. A protruding end 48 is provided at the bottom of the inner arc surface of the liquid-through sleeve 47, and a diverter bottom end 49 is provided on the lower surface of the liquid inlet tube body 44. A liquid inlet hole 491 is provided on the upper surface of the diverter bottom end 49. A plug-in end 410 is provided on the top of the outer arc surface of the liquid inlet tube body 44, and one end of the plug-in end 410 is movably connected to the ejection assembly 6. An extension end is provided in the middle of the lower surface of the diverter bottom end 49. A sleeve 5 is sleeved on the middle extension end of the diversion bottom end 49, and a flange portion 51 is provided in the middle of the outer arc surface of the sleeve 5. The lower surface of the flange portion 51 is placed on the top of the protruding end 48, and a spring 52 is fixedly installed between the flange portion 51 and the protruding end 48. A float 53 is fitted and connected to the upper surface of the protruding end 48, and the outer arc surface of the float 53 is fixedly installed on one end of the spring 52.

[0050] Specifically, the control transmission shaft 11 drives the piston 10 in the rear cover 8 to perform regular linear reciprocating motion at a constant angular velocity. When the piston 10 moves forward, the emulsified oil inside the liquid inlet tube body 44 is quickly compressed by this powerful thrust. At the same time, as the piston 10 continues to move forward, the compressed air is quickly and orderly transmitted to the closed cavity between each kit along the air path.

[0051] Under the action of this high-pressure airflow, the spring 52 causes the sleeve 5 to move and undergo elastic deformation. On the one hand, it absorbs part of the pressure through its own deformation, and on the other hand, it cleverly converts this energy into a thrust on the liquid sleeve 47. Under this dual force, the fully mixed emulsion in the liquid sleeve 47 is ejected at high speed from the column cavity end 43 on the front side of the converging sleeve 41.

[0052] The multi-way solenoid valve 3 adjusts the ejected emulsion in real time. When the hydraulic support and other equipment are in light load condition, the solenoid valve 3 responds quickly to reduce the valve core opening and accurately limit the emulsion delivery flow. When the equipment encounters heavy load challenge, the solenoid valve 3 can quickly adjust to increase the opening to ensure sufficient emulsion supply.

[0053] At the same time, the diameter of the inner cavity of the inner sleeve body 66, combined with the high-speed impact of the water flow, forms a mixing effect. When the water flows from the pipeline A7 through the compression kit 65 into the inner sleeve body 66, under the dual effects of gravity and pressure, the water flows into the liquid inlet pipe body 44 at a high flow rate. At the moment when the water flow meets the emulsified oil, the powerful impact force acts like an efficient agitator, instantly breaking up and mixing the emulsified oil to form a uniform and stable emulsion.

[0054] Since the entire cavity system adopts a sealing structure, the pressure generated by each push of the piston 10 can be completely transmitted and maintained consistent. Every time the piston 10 is pushed forward, the column cavity end 43 will spray the emulsion once, ensuring the stability and reliability of the output process. By adjusting the rotation speed of the control transmission shaft 11, the reciprocating motion frequency of the piston 10 can be flexibly changed, thereby realizing continuous adjustment of the emulsion output flow rate, realizing reasonable distribution and flow coordination of the emulsion between the pumps, and avoiding problems such as uneven flow and pressure fluctuations. In addition, the injection can also reduce the energy consumption of the system to a certain extent, improve the energy utilization efficiency of the pump station, make the pump station operation more stable and reliable, and meet the high requirements under complex working conditions such as coal mine comprehensive mining working faces.
