Description

Technical Field

[0001] The utility model belongs to the technical field of mine slurry filling auxiliary tools, in particular to a mine filling slurry moisture suction device. Background Art

[0002] In order to support the rock formation, control ground pressure activity in the mining area, prevent surface subsidence, protect the surface, and also to maximize the recovery of mineral resources, slurry is usually filled in the mine after mining. In the mine filling operation, the concentration of the filling slurry is crucial to the strength and stability of the filling body. Under normal circumstances, there are two factors that affect the concentration of the filling slurry. First, due to the production fluctuations of the thickening device, the concentration of the tailings output to the filling station is lower than the tailings concentration required by the design, resulting in excess water. Second, the filling slurry will flush the pipeline before and after filling, and the lubricating water and pipe washing water will mix with the filling slurry, reducing the concentration of the filling slurry. The concentration of the mine filling slurry directly affects the construction process. Therefore, certain measures are used in the existing technology to adjust the concentration of the filling slurry.

[0003] As a method of adjusting the slurry concentration, suction dewatering has the advantages of high efficiency and flexible use. The implementation of suction dewatering is inseparable from a suction device. At present, such suction devices in related technologies are all water pumps. Specifically, the water pump is directly connected to the seepage pipe inserted into the slurry. When the water pump is energized, the water pump generates suction and sucks the water out of the slurry through the seepage pipe.

[0004] Although the direct suction method of the water pump is very efficient, the amount of water generated per unit time when the filling slurry exudes water is limited. During suction, it cannot be guaranteed to be full of water at all times, especially when the slurry concentration adjustment is nearing the end, the water volume is small, and the water pump running at full power has the problem of power waste. In other words, direct suction of the water pump will result in excess power, high energy consumption, and the suction force generated by the water pump is very large, which will increase the probability of small particles of solid matter in the slurry being sucked away.

[0017] Furthermore, in order to better implement the present invention, an overflow port is provided on the top of the water tank.

[0018] Furthermore, in order to better implement the present invention, the bottom of the circulation box is configured as a funnel-shaped structure, and the second circulation water pipe is connected to the constricted end of the funnel-shaped structure.

[0019] Furthermore, in order to better implement the present invention, a filter is installed on the inner wall of the water tank, and the filter covers the pipe opening of the first circulating water pipe to prevent particulate impurities from entering the first circulating water pipe from the water tank.

[0020] Furthermore, in order to better implement the present invention, a through groove is opened on the side wall of the water tank, and the through groove extends from the top of the water tank to the bottom of the water tank;

[0025] A stud is protruding from the outer wall of the water tank, and a through hole is provided on the connecting plate. The stud passes through the through hole and is screwed to a nut, so that the connecting plate is press-fitted onto the outer wall of the water tank by using the nut.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The utility model provides a mine filling slurry moisture suction device, which includes a water tank, a water pump, a circulation box and a branch pipe. The top of the water tank is sealed by a box top cover, a water inlet is opened on the box top, and a connecting pipe is arranged on the upper side wall of the water tank. The connecting pipe is used to connect the drainage pipe. The water inlet end of the water pump is connected to the lower part of the water tank through the first circulation water pipe, and the water outlet end of the water pump is connected to the second circulation water pipe. The circulation box is placed in the water inlet, and the free end of the second circulation water pipe is inserted into the circulation box from top to bottom. A third circulation water pipe is arranged at the bottom of the circulation box. The third circulation water pipe is located in the water tank and extends to the bottom of the first circulation water pipe. The branch pipe is arranged on the side wall of the circulation box. The branch pipe is used to connect the secretion pipe, and the branch pipe is located above the free end of the second circulation water pipe.

[0028] When in use, first inject a certain amount of water into the water tank so that the water submerges the pipe mouth of the above-mentioned first circulating water pipe and the free end of the above-mentioned third circulating water pipe, and then start the water pump. The water pump draws water from the water tank through the first circulating water pipe and injects the water into the second circulating water pipe. The second circulating water pipe flushes the water into the middle and lower position of the above-mentioned circulation box. Part of the water accumulates in the middle and lower position of the circulation box and submerges the free end of the second circulating water pipe, and most of the water will flow away from the third circulating water pipe and eventually flow back into the inside of the water tank. Since the free end of the third circulating water pipe is located below the first circulating water pipe, the water flowing back into the water tank can submerge the free end of the third circulating water pipe. In this way, a relatively closed closed-loop water channel can be formed in the water tank, water pump, first circulating water pipe, second circulating water pipe, circulation box and third circulating water pipe. Because the branch pipe is located above the free end of the second circulating water pipe, and water flows directly from the free end of the second circulating water pipe into the lower part of the circulation box, water in the circulation box does not reach the opening of the branch pipe and therefore does not enter the branch pipe. When water in the circulation box flows out of the third circulating water pipe at a certain flow rate, it creates a negative pressure in the upper-center space of the circulation box. Since the branch pipe is connected to the upper-center part of the circulation box, this negative pressure also forms in the branch pipe and in the seepage pipe connected to it. When the seepage pipe is inserted into the mine filling slurry, the negative pressure automatically causes moisture in the mine filling slurry to enter the seepage pipe. This negative pressure then flows through the seepage pipe, the second connecting pipe, the main pipe, and the first connecting pipe, pumping water into the branch pipe and the circulation box, ultimately flowing into the water tank through the third circulating water pipe. When the water in the water tank is high enough that the liquid level reaches the connecting pipe, the water is discharged through the connecting pipe.

[0029] With this structure, the device leverages the high-speed flow of water below the circulation box to create negative pressure in the upper and middle chambers of the circulation box. This system, utilizing the principle of siphoning, extracts moisture from the mine filling slurry. This makes it suitable for mine filling slurries of varying concentrations and highly practical. The water pump merely provides power within the closed-loop waterway, allowing water to flow through it and thereby generate negative pressure at the branch pipes. This reduces the pump's energy output, requiring less power and thus reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0039] Example:

[0040] like Figure 1-Figure 5 As shown, the mine filling slurry moisture extraction device provided in this embodiment includes a water tank 100, a water pump 300, a circulation box 600 and a branch pipe 800, wherein:

[0041] The top of the water tank 100 is sealed by a top cover, which can be a cover plate bolted to the top of the water tank 100 and can be removed to open the water tank 100. A water inlet is provided at the top of the tank, and a connecting pipe 200 is provided on the upper side wall of the water tank 100 for connecting to a drain pipe. The water inlet of the water pump 300 is connected to the lower portion of the water tank 100 via a first circulating water pipe 400, and the water outlet of the water pump 300 is connected to a second circulating water pipe 500. A circulating box 600 is placed in the water inlet, and the free end of the second circulating water pipe 500 is inserted into the circulating box 600 from top to bottom and extends to the lower area of ​​the circulating box 600. A third circulating water pipe 700 is connected to the bottom of the circulating box 600. The third circulating water pipe 700 is located in the water tank 100 and extends to the bottom of the first circulating water pipe 400. The branch pipe 800 is connected to the side wall of the circulating box 600. The branch pipe 800 is used to connect the secretion pipe, and the branch pipe 800 is located above the free end of the second circulating water pipe 500.

[0042] When in use, first inject a certain amount of water into the water tank 100 so that the water submerges the nozzle of the first circulating water pipe 400 and the free end of the third circulating water pipe 700. Then start the water pump 300, the water pump 300 pumps the water in the water tank 100 through the first circulating water pipe 400 and injects the water into the second circulating water pipe 500. The second circulating water pipe 500 flushes the water into the middle and lower position of the above-mentioned circulating box 600. Part of the water accumulates in the middle and lower position of the circulating box 600 and submerges the free end of the second circulating water pipe 500. From the end, most of the water will flow out of the third circulating water pipe 700 and eventually flow back into the water tank 100. Since the free end of the third circulating water pipe 700 is located below the first circulating water pipe 400, the water flowing back into the water tank 100 can submerge the free end of the third circulating water pipe 700. In this way, a relatively closed closed-loop water channel can be formed in the water tank 100, the water pump 300, the first circulating water pipe 400, the second circulating water pipe 500, the circulation box 600 and the third circulating water pipe 700. Since the branch pipe 800 is located above the free end of the second circulating water pipe 500, and water directly rushes to the lower part of the circulation box 600 from the free end of the second circulating water pipe 500, the water in the circulation box 600 will not reach the pipe mouth of the above-mentioned branch pipe 800, so the water will not enter the branch pipe 800. When the water in the circulation box 600 flows away from the third circulating water pipe 700 at a certain flow rate, a negative pressure will be formed in the upper and middle space inside the circulation box 600. The above-mentioned branch pipe 800 is connected to the upper and middle part of the circulation box 600. Therefore, a negative pressure will also be formed in the branch pipe 800, and a negative pressure will also be formed in the seepage pipe connected to the branch pipe 800. When the seepage pipe is inserted into the mine filling slurry, the negative pressure will cause the moisture in the mine filling slurry to automatically enter the seepage pipe, and in turn pass through the seepage pipe, the second connecting pipe, the main pipe and the first connecting pipe to pump the water to the branch pipe 800 and the inside of the above-mentioned circulation box 600, and finally flow into the water tank 100 from the third circulating water pipe 700. When there is a lot of water in the water tank 100 and the liquid level reaches the connecting pipe 200 , the water will be drained from the connecting pipe 200 .

[0043] Through the above structure, the device uses the high-speed water flowing in the lower part of the circulation box 600 to form a negative pressure in the middle and upper space of the circulation box 600, and uses the principle of siphon to suck the moisture in the mine filling slurry. It can be applied to mine filling slurries of different concentrations and has strong practicality. The water pump 300 is only used to provide power in the above-mentioned closed-loop waterway, so that water flows in the above-mentioned closed-loop waterway, thereby generating negative pressure at the branch pipe 800. In this way, the energy output of the water pump 300 only needs to be sufficient to make the water flow in the above-mentioned closed-loop waterway, and the required power is smaller, thereby reducing energy consumption. The device uses the siphon principle to suck the moisture in the mine filling slurry, and the suction force is more appropriate, which can effectively avoid the particulate matter in the slurry being sucked away.

[0044] Optionally, to prevent water from entering the branch pipe 800 from the circulation box 600, a one-way valve 810 is installed in the branch pipe 800, allowing only water to flow back into the circulation box 600. Of course, if the water volume is controlled so that the water level in the circulation box 600 does not reach the outlet of the branch pipe 800, then the one-way valve 810 is not necessary.

[0045] Optionally, a flow detection unit 210 is also installed on the connecting pipe 200. The flow detection unit 210 is used to measure the amount of water flowing through the connecting pipe 200, so that the user can timely understand the amount of water extracted from the slurry. Of course, the flow detection unit 210 can also be installed on the branch pipe 800. Specifically, the flow detection unit 210 is a water meter or a flow sensor. In addition, a water quality monitoring device is also installed on the branch pipe 210 to monitor the water quality of the extracted water.

[0046] Optionally, a partition 110 extending to the middle of the water tank 100 is provided between the bottom and the side wall of the water tank 100. The internal space of the water tank 100 is divided into a lower left chamber, a lower right chamber and an upper chamber located above the lower left chamber and the lower right chamber through the partition 110. The upper chamber is connected to the lower left chamber and the lower right chamber. The first circulating water pipe 400 is connected to the lower left chamber, the third circulating water pipe 700 is inserted into the lower right chamber, and the connecting pipe 200 is connected to the side wall of the upper chamber. In this way, it can be ensured that the free end of the third circulating water pipe 700 can be submerged in water. Specifically, when water flows into the water tank 100 from the third circulating water pipe 700, the water directly reaches the above-mentioned lower right chamber. Only when the lower right chamber is full will it flow from the upper chamber into the above-mentioned lower left chamber. Because the free end of the third circulating water pipe 700 penetrates deep into the lower right chamber, the partition 110 can effectively ensure that the free end of the third circulating water pipe 700 is submerged in water during operation.

[0047] In order to avoid excessive water in the water tank 100, in this embodiment, an overflow port 120 is further opened on the top of the water tank 100. When the water in the water tank 100 is full, the water can flow out from the overflow port.

[0048] In order to ensure that water can flow smoothly from the third circulating water pipe 700, the bottom of the circulation box 600 in this embodiment is set to a funnel-shaped structure, and the above-mentioned third circulating water pipe 700 is connected to the narrowed end of the funnel-shaped structure.

[0049] To prevent impurities in the water tank 100 from entering the first circulating water pipe 400 and ultimately the water pump 300, thereby affecting the safe operation of the water pump 300, a filter 130 is installed on the inner wall of the water tank 100 in this embodiment. The filter 130 covers the nozzle of the first circulating water pipe 400 to prevent particulate impurities from entering the first circulating water pipe 400 from the water tank 100. Specifically, the mesh size of the filter 130 is 500 mesh.

[0050] Optionally, in this embodiment, a through slot is formed in the side wall of the water tank 100, extending from the top to the bottom of the water tank 100. A transparent viewing window 140 is installed in the through slot. The viewing window 140 may be a tempered glass window or a transparent plastic window. This facilitates the user to observe the specific conditions in the water tank 100 in real time.

[0051] More preferably, the mine filling slurry moisture extraction device provided in this embodiment further includes a connecting frame 900, which is composed of a sleeve 910, a shock-absorbing rubber pad 920, a connecting rod 930, and a connecting plate 940, wherein the connecting rod 930 is fixedly connected between the sleeve 910 and the connecting plate 940. The sleeve 910 is sleeved on the branch pipe 800, and the shock-absorbing rubber pad 920 is padded between the inner wall of the sleeve 910 and the outer wall of the branch pipe 800. A stud 150 is protruded from the outer wall of the water tank 100, and a through hole is defined in the connecting plate 940. The stud 150 passes through the through hole and is screwed to a nut 160, so that the nut 160 can be used to press the connecting plate 940 onto the outer wall of the water tank 100. In this way, the branch pipe 800 and the circulation box 600 can be connected to the outer wall of the water tank 100 to support the branch pipe 800 and the circulation box 600. Since the circulation box 600 is connected to the water pump 300 through the second circulation water pipe 500, the operation of the water pump 300 will generate vibration, and the vibration will be transmitted to the circulation box 600 through the second circulation water pipe 500. Through the connecting frame 900, the circulation box 600 can be installed more stably, and the setting of the shock-absorbing rubber pad 920 can absorb part of the vibration, thereby playing a role in shock absorption and noise reduction.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
