Description

Technical Field

[0001] This application relates to the field of goaf filling, and in particular to a pumping valve that can automatically adjust the direction of slurry pumping and its application method. Background Technology

[0002] Backfill mining is a mining method with high recovery rate and low dilution loss rate, and it is currently widely used in mine production both domestically and internationally. The quality of the backfill material has significant advantages in controlling site stress and surrounding rock stability. However, the backfill mining process requires flushing the pipelines. During mining operations, the backfill material in the goaf mixes with the pipeline flushing water, thus greatly affecting the strength of the backfill material. The actual strength often falls far short of the design strength, and over time, it may even form a sludge-like backfill, which has a significant impact on underground production safety.

[0003] The current conventional methods are: (1) When lubricating the pipe, after the clean water reaches the pipe outlet, the underground operator must return the signal to the preparation station before slurry preparation and sand release for filling can begin. At the end of filling, the pipe must also be flushed to remove the residual slurry in the pipe until clean water flows out of the underground pipe outlet. (2) Install a drainage system such as corrugated pipes in the goaf to drain the accumulated water in the goaf. The two commonly used methods require a lot of labor or material costs, and the drainage system is easily blocked by the filling aggregate, often failing to achieve the desired effect. Summary of the Invention

[0004] In order to ensure the strength of the filling material while flushing the pipeline, this application provides a pumping valve that can automatically adjust the pumping direction of the slurry; by pumping water at low pressure and slurry at high pressure, the flushing water and the filling slurry can be effectively separated.

[0005] In a first aspect, this application provides a pumping valve that can automatically adjust the pumping direction of slurry, employing the following technical solution:

[0006] A pumping valve capable of automatically adjusting the pumping direction of slurry includes a pump body, the pump body comprising a main pipeline and a regulating chamber, the main pipeline having a grouting port and a high-pressure slurry outlet; the regulating chamber communicating with the main pipeline and located between the grouting port and the high-pressure slurry outlet, the regulating chamber also having a low-pressure water outlet; a slurry stop valve rotatably connected to the high-pressure slurry outlet, and a water stop valve rotatably connected to the low-pressure water outlet, the slurry stop valve and the water stop valve rotating to respectively open and close the high-pressure slurry outlet and the low-pressure water outlet; the pump body also having a drive assembly for controlling the rotation of the water stop valve and the slurry stop valve.

[0007] By adopting the above technical solution, a water outlet and a high-pressure slurry outlet are respectively set up. When the pipeline is being rinsed and flushed with clean water, the drive component rotates the water stop valve and the slurry stop valve to open the water stop valve and close the slurry stop valve, so that the clean water is discharged through the low-pressure water outlet to a position far away from the goaf, thus preventing it from entering the goaf and preventing the filling material from mixing with the water used to clean the pipeline in the goaf. When it is necessary to fill the goaf, the drive component drives the slurry stop valve and the water stop valve to rotate, thereby opening the high-pressure slurry outlet and closing the water outlet. This allows the filling material to enter the goaf smoothly and avoids the filling material from being affected by mixing with the rinsing water.

[0008] Optionally, the drive assembly includes a moving valve, a drive chamber, a first pull rope, a second pull rope, and a stabilizing spring; the stabilizing spring is used to limit the rotation of the slurry stop valve; the drive chamber is connected to the regulating chamber, the moving valve is slidably connected to the drive chamber along the length of the drive chamber, one end of the first pull rope is connected to the moving valve, and the other end first passes through the drive chamber, then through the pump body and is connected to the slurry stop valve; one end of the second pull rope is connected to the moving valve, and the other end first passes through the drive chamber, then through the regulating chamber and is connected to the water stop valve; the moving valve slides to drive the slurry stop valve and the water stop valve to rotate, when the moving valve is located near the regulating chamber, the water stop valve opens the low-pressure outlet, and the slurry stop valve closes the high-pressure slurry outlet; the pump body is also provided with a trigger assembly for driving the moving valve to slide.

[0009] By adopting the above technical solution, when the pipeline is neither pumping clean water nor filling material, the movable valve is located at the end near the regulating chamber. At this time, the high-pressure slurry outlet is closed and the low-pressure water outlet is open. When clean water is pumped in the pipeline, the high-pressure slurry outlet remains closed under the action of the stabilizing spring. After the clean water flows through the main pipeline, it leaves from the low-pressure water outlet of the regulating chamber. When filling material is pumped in the pipeline, since the pumping pressure when pumping filling material is greater than the pumping pressure when pumping clean water, the trigger component drives the movable valve to slide. The stop valve begins to rotate under the action of gravity to close the low-pressure water outlet. At the same time, the movable valve slides and pulls the stop valve through the pull rope to start rotating. After the stop valve rotates, the high-pressure slurry outlet opens, allowing the filling material to flow into the goaf through the high-pressure slurry outlet to complete the filling.

[0010] Optionally, a groove is provided on the side wall of the drive chamber along its own length, and the movable valve is slidably connected in the groove.

[0011] By adopting the above technical solution, the slide groove one provides a guiding function for the sliding of the movable valve, enabling it to slide smoothly along the direction of the drive chamber, and preventing it from rotating in the drive chamber and causing the pull rope one and pull rope two to become entangled.

[0012] Optionally, the triggering component includes a regulating valve and a regulating spring. The regulating valve is slidably connected in the regulating chamber along the length of the drive chamber. The regulating chamber has an abutment surface for the regulating valve to abut against. The regulating spring is used to drive the regulating valve to abut against the abutment surface. When the regulating valve abuts against the abutment surface, the regulating chamber is not connected to the main pipeline. The regulating valve is also provided with a push block that can extend into the drive chamber and abut against the moving valve to drive it to slide. When the regulating valve abuts against the abutment surface, the push block does not abut against the moving valve.

[0013] By adopting the above technical solution, when clean water is pumped into the main pipeline, the regulating valve receives water pressure and begins to move upward, thereby connecting the regulating chamber with the main pipeline. At this time, the push block does not push the moving valve, so the low-pressure outlet remains open, and the water flow can be discharged from the low-pressure drain to a location far away from the goaf. When filler is pumped into the main pipeline, the regulating valve receives greater pressure and thus rises to a greater extent. At this time, the push block pushes the moving valve to move, and the stop valve can rotate under the action of gravity, thereby closing the low-pressure outlet. At this time, the moving valve pulls the stop valve to rotate through the pull rope one, thereby opening the high-pressure slurry outlet. The filler can be discharged from the high-pressure slurry outlet to the goaf. When the injection of filler stops, the regulating valve re-abuts the contact surface under the action of the regulating spring and gravity. The moving valve falls to the end near the regulating chamber under the action of gravity. The stop valve is pulled up again under the action of the pull rope two to open the low-pressure outlet. The stop valve rotates under the action of the stabilizing spring and gravity to re-close the high-pressure slurry outlet, thereby returning to the initial state.

[0014] Optionally, a second sliding groove is provided on the side wall of the regulating chamber along the length direction of the driving chamber, and the regulating valve is slidably connected in the second sliding groove.

[0015] By adopting the above technical solution, the second slide provides a guiding function for the regulating valve, preventing the regulating valve from deflecting and causing the push block to fail to insert into the drive chamber.

[0016] Optionally, the regulating chamber is further provided with an isolation membrane, one end of which is connected to the side wall of the regulating chamber, and the other end of which is connected to the regulating valve; the isolation membrane separates the space of the regulating valve near the regulating spring from the space of the regulating valve away from the regulating spring.

[0017] By adopting the above technical solution, after the isolation membrane separates the spaces on both sides of the regulating valve, neither clean water nor filler can enter the space on the side of the regulating spring, ensuring that the pumping pressure can push the regulating valve to a certain extent; at the same time, it can also prevent filler from entering the space on the upper side of the regulating valve 31 and affecting the compression of the pressure regulating spring.

[0018] Optionally, a control valve is slidably connected to the main pipeline, the control valve sliding to separate the regulating chamber from the main pipeline; a spring retainer is also provided on the main pipeline, one end of a control spring is fixedly connected to the spring retainer, and the other end of the control spring is fixedly connected to the control valve; a pull rope three is also connected to the movable valve, one end of the pull rope three is connected to the movable valve, and the other end of the pull rope three first passes out of the drive chamber, then passes into the main pipeline and is connected to the end of the control valve away from the control spring; when the control spring is in its natural state, the regulating chamber is connected to the main pipeline.

[0019] By adopting the above technical solution, when clean water is pumped into the main pipeline, the moving valve does not move and the control valve does not slide. At this time, the regulating chamber is connected to the main pipeline, and the clean water can be discharged from the low-pressure outlet of the regulating chamber. When the pipeline cleaning is completed and the filling material is pumped in, the moving valve slides and the control valve slides under the action of the pull rope three, which finally separates the regulating chamber from the main pipeline, preventing the filling material from entering the regulating chamber and preventing the filling material in the chute two from not being cleaned properly, which would cause the regulating valve to slide poorly.

[0020] Secondly, this application also provides an application method for a pumping valve that can automatically adjust the pumping direction of slurry, using the following technical solution:

[0021] A method for applying a pumping valve capable of automatically adjusting the pumping direction of slurry, using the pumping valve capable of automatically adjusting the pumping direction of slurry as described in any one of claims 1-7, includes the following steps:

[0022] Step 1: Rinse, using low pressure, pump clean water into the main pipeline;

[0023] Step 2: Grouting, using high pressure to pump the filler material into the main pipeline;

[0024] Step 3: Rinse. Use a low-pressure pump to send clean water into the main pipeline to clean the pipeline again.

[0025] By adopting the above technical solution, the clean water used to wash the pipeline and the filling material used to fill the goaf are discharged to different locations, so as to avoid the clean water used to wash the pipeline from mixing with the filling material and affecting the strength of the filling material.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] This application, through the configuration of the main pipeline, regulating chamber, drive component, and trigger component, enables the low-pressure water outlet and high-pressure slurry outlet to open or close automatically, thereby separating the clean water from the filler material in the washing pipeline and preventing them from coming into contact with each other, thus ensuring the strength of the filler material.

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a pumping valve that can automatically adjust the pumping direction of slurry, with reference to... Figure 1 The pumping valve includes a main pipeline 2 and a regulating chamber 3. The main pipeline 2 is provided with a grouting port 21 and a high-pressure grouting port 22. The regulating chamber 3 is connected to the main pipeline 2 and is located between the grouting port 21 and the high-pressure grouting port 22. The regulating chamber 3 is also provided with a low-pressure water outlet 33, thus forming a three-way structure. At the same time, a stop valve 32 is rotatably connected to the low-pressure water outlet 33, and a stop valve 24 is rotatably connected to the high-pressure grouting port 22. The stop valve 24 and the stop valve 32 rotate to control the opening and closing of the high-pressure grouting port 22 and the low-pressure water outlet 33, respectively. The pump body 1 is also provided with a drive assembly for controlling the stop valve 32 and the stop valve 24.

[0035] In this embodiment, the drive assembly includes a moving valve 41, a drive chamber 4, a pull rope 25, a pull rope 34, and a stabilizing spring 23. One end of the stabilizing spring 23 is fixedly connected to the grout stop valve 24, and the other end of the stabilizing spring 23 is fixedly connected to the main pipe 2. The stabilizing spring 23 is located between the grouting port 21 and the high-pressure grout outlet 22. The drive chamber 4 is connected above the regulating chamber 3. A sliding groove 42 is provided in the drive chamber 4 along its own length direction. The moving valve 41 is slidably connected in the sliding groove. The sliding groove provides guidance for the sliding of the moving valve 41 and at the same time prevents the moving valve 41 from rotating in the drive chamber 4.

[0036] One end of the pull rope 25 is connected to the movable valve 41, and the other end of the pull rope 25 enters the drive chamber 4 from above, passes over the drive chamber 4 and the regulating chamber 3, and then enters the main pipe 2 and connects to the slurry stop valve 24; one end of the pull rope 34 is connected to the movable valve 41, and the other end of the pull rope 34 enters the drive chamber 4 from above, passes over the drive chamber 4 and the regulating chamber 3, and then enters the regulating chamber 3 and connects to the water stop valve 32; at the same time, the regulating chamber 3 is also equipped with a trigger component that can push the movable valve 41 to slide different distances according to the injection of different media.

[0037] refer to Figure 1 When no medium is pumped into the main pipeline 2, the movable valve 41 is located at the end of the drive chamber 4 near the regulating chamber 3; and at this time, the stop valve 32 is pulled up by the pull rope 2 34, and the low-pressure outlet 33 is opened; at the same time, the pull rope 1 25 remains slack, and the slurry stop valve 24 closes the high-pressure slurry outlet 22 under the action of the stabilizing spring 23 and gravity.

[0038] Reference Figure 2 When clean water is injected into the main pipe 2, the trigger component drives the moving valve 41 to move upward. At this time, the stabilizing spring 23 resists the pressure generated by the water pressure on the stop valve 24, the pull rope 1 25 is not fully taut, and the high pressure outlet 22 remains closed. At this time, the pull rope 2 34 remains slack, and the stop valve 32 begins to rotate under the action of gravity but does not close the low pressure outlet 33. The washing water can still be discharged from the low pressure outlet 33.

[0039] In this embodiment, the triggering component includes a regulating valve 31 and a regulating spring 35. The regulating chamber 3 has a second sliding groove 37 along the length of the driving chamber 4, and the regulating valve 31 is slidably connected in the second sliding groove 37. The regulating chamber 3 has an abutment surface 38 on the side away from the driving chamber 4 for the regulating valve 31 to abut. The regulating valve 31 has a frustum structure that is larger at the top and smaller at the bottom. When the regulating valve 31 abuts the abutment surface 38, the regulating valve 31 separates the regulating chamber 3 from the main pipe 2. The two ends of the regulating spring 35 are respectively installed on the top wall of the regulating chamber 3 and the regulating valve 31. At the same time, the regulating valve 31 is also provided with a push block 311 that can penetrate into the driving chamber 4 and abut against the moving valve 41 to move it. When the regulating valve 31 abuts the abutment surface 38, the regulating spring 35 is in a slightly compressed state, and the push block 311 abuts against the moving valve 41.

[0040] When clean water is pumped in by the low-pressure pump, the regulating valve 31 receives pressure and begins to move upward, and the regulating chamber 3 is connected to the main pipeline 2. However, at this time, the pull rope 25 is not yet taut, and the slurry stop valve 24 always closes the high-pressure slurry outlet 22, so that the clean water can be discharged from the low-pressure outlet 33 to an area far away from the goaf.

[0041] Reference Figure 3 When the high-pressure pump injects filler material, the regulating valve 31 moves upward and drives the moving valve 41 through the push block 311. The second pull rope 34 begins to loosen, and the water stop valve 32 gradually rotates until it closes the low-pressure outlet 33. Then the first pull rope 25 is fully taut, and the slurry stop valve 24 is gradually pulled open by the first pull rope 25 as the moving valve 41 moves upward, allowing the filler material to be discharged from the high-pressure slurry outlet 22 into the goaf.

[0042] It should be noted that, since there is a certain distance between the push block 311 and the moving valve 41 in the initial state, when clean water is pumped in, if the pumping pressure is less than a certain value, the push block 311 will not push the moving valve 41, and the stop valve 32 will not rotate, so that the low-pressure drain outlet can drain water with maximum efficiency within a certain pressure range.

[0043] To ensure that the pumping pressure can push the regulating valve 31 to a certain extent and allow the slurry stop valve 24 to open fully, an isolation membrane 36 is also provided in the regulating chamber 3. One end of the isolation membrane 36 is connected to the side wall of the regulating chamber 3, and the other end of the isolation membrane 36 is connected to the regulating valve 31, thereby separating the upper and lower parts of the regulating valve 31 and preventing clean water or filler from entering the upper part of the regulating valve 31 and affecting the expansion and contraction of the regulating valve 31. At the same time, several exhaust ports 39 are also provided on the top wall of the regulating valve 31 to balance the air pressure inside and outside the regulating chamber 3.

[0044] Finally, to prevent excessive filler material from entering the regulating chamber 3 and adhering to the side wall of the regulating chamber 3 and the slide groove 37, causing the regulating valve 31 to slide poorly, a control valve 27 is also slidably connected in the main pipeline 2. The control valve 27 slides to separate the regulating chamber 3 from the moving chamber. A spring retainer 26 is provided on the main pipeline 2, and a section of the control spring 28 is fixedly connected to the spring retainer 26. The other end of the control spring 28 is fixedly connected to the control valve 27. When the control spring 28 is in its natural state, the regulating chamber 3 is connected to the main pipeline 2. At the same time, one end of the pull rope 29 is also connected to the moving valve 41. The other end of the pull rope 29 passes out of the driving chamber 4 from the top of the driving chamber 4, goes around the side of the regulating chamber 3 away from the low-pressure drain port, and then enters the main pipeline 2, and connects to the section of the control valve 27 away from the control spring 28.

[0045] When high-pressure pumping of filler material is used, the moving valve 41 rises, driving the control valve 27 to move until the regulating chamber 3 is separated, preventing filler material from entering the regulating chamber 3. At this time, the control spring 28 is in the extended state. When pumping of filler material stops, the slurry stop valve 24 starts to rotate under the action of the stabilizing spring 23 and gravity, and drives the moving valve 41 and the regulating valve 31 to move down. The pull rope 39 begins to loosen, the pull rope 24 begins to straighten, the control valve 27 resets under the action of the control spring 28, and the water stop valve 32 resets under the action of the moving valve 41. The entire device returns to its initial state.

[0046] Finally, a roller assembly is also provided on the pump body 1. Pull rope 1 25, pull rope 2 34 and pull rope 3 29 are all mounted on the roller assembly. At the same time, a limiter 5 is also provided on the main pipeline 2 to prevent the water stop valve 32 and the slurry stop valve 24 from rotating excessively and affecting the sealing effect.

[0047] The implementation principle of a pumping valve that can automatically adjust the pumping direction of slurry in this application embodiment is as follows: by moving valve 41, adjusting valve 31 and adjusting spring 35, moving valve 41 is made to have different displacements when the pumping pressure is different; the different displacements of moving valve 41 will be reflected to slurry stop valve 24, water stop valve 32 and control valve 27 through pull rope 1 25, pull rope 2 34 and pull rope 3 29, thereby automatically controlling the opening and closing of low pressure outlet 33 and high pressure slurry outlet 22; thus, the main pipeline 2 can automatically discharge the water for washing the pipeline and the filling material to different positions during low pressure water injection and high pressure grouting, ensuring the strength of the filling material.

[0048] This application also discloses an application method for a pumping valve that can automatically adjust the pumping direction of slurry, which includes the following steps:

[0049] Step 1: Rinse, using low pressure, pump clean water into main pipe 2;

[0050] Step 2: Grouting. Gradually increase the pumping pressure until the critical pressure required to open the grout stop valve 24 is reached. Then, start pumping the filler material and increase the pumping pressure again to a certain extent.

[0051] Step 3: Rinse. Use a low-pressure pump to send clean water again to clean the pipes.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
