Description

Technical Field

[0001] The invention belongs to the technical field of mine slurry filling auxiliary tools, and in particular relates to an auxiliary mine slurry filling stope dewatering system. Background Art

[0002] In order to support the rock formation, control ground pressure activities in the mining area, prevent surface subsidence, protect the surface, and also to maximize the recovery of mineral resources, the mine is usually filled with slurry 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 to reduce the concentration of the filling slurry. The concentration of the mine filling slurry directly affects the construction progress. Therefore, certain measures are used in the existing technology to adjust the concentration of the filling slurry. At present, there are three common measures:

[0003] The first is to optimize the slurry formula and reduce the slurry water seepage rate by improving the slurry composition, thereby improving the strength and stability of the filling body; the second is to improve the thickening device and increase the concentration of tailings transported by low flow to reduce the entry of excess water into the filling slurry and reduce the water seepage phenomenon during the filling process; the third is to use the filling retaining wall for dehydration, set up retaining walls and drainage pipes during the filling process to guide the discharge of excess water to reduce the moisture content in the filling body.

[0004] However, no matter which measure is used, there are certain limitations. Especially for filling slurry with high water seepage rate, dehydration efficiency is particularly important. The water seepage efficiency of the second and third measures mentioned above is not high, and the first measure has the disadvantage of a long research and development cycle. In addition, the current measures all have technical problems such as high cost and inflexible use, and the economy and practicality of mine filling slurry dehydration are low.

DETAILED DESCRIPTION

[0053] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0054] Example:

[0055] The auxiliary mine filling slurry stope dewatering system provided in this embodiment is as follows Figure 1-Figure 7 As shown, it includes a water seepage pipe 100, a main pipe 200 and a siphon device 300, wherein:

[0056] The wall of the seepage pipe 100 is provided with a water screening channel. When the seepage pipe 100 is inserted into the mine filling slurry, the water in the mine filling slurry passes through the water screening channel and enters the seepage pipe 100. Of course, the insertion end of the seepage pipe 100 inserted into the mine filling slurry needs to be closed to prevent the mine filling slurry from entering the seepage pipe 100 from this end. The water screening channel only allows water to pass through, and solid objects in the mine filling slurry cannot pass through.

[0057] A plurality of seepage pipes 100 are connected to the pipe wall of the main pipe 200, and the main pipe 200 is connected to a siphon device 300, which is used to generate negative pressure in the main pipe 200 and the seepage pipe 100 to suck the water entering the seepage pipe 100. The setting of the main pipe 200 concentrates the water in the plurality of seepage pipes 100, so as to centrally process or discharge the water released from the mine filling slurry.

[0058] When in use, multiple seepage pipes 100 are simultaneously inserted into the mine filling slurry, so that the seepage pipes 100 must be below the slurry liquid level. Since the seepage pipes 100 are hollow, they must be below the liquid level to be able to siphon, and the multiple seepage pipes 100 are distributed in different positions, specifically, Figure 8 and Fig. 9 As shown, when the seepage pipe 100 is inserted into the mine filling slurry, a shore frame-type pipe insertion and extraction device 800 near the insertion position is first installed. The pipe insertion and extraction device 800 includes a frame 810, on which two rollers 820 are rotatably installed. A guide gap is formed between the two rollers 820. The seepage pipe 100 is inserted into the guide gap, and the outer wall of the seepage pipe 100 contacts the two rollers 820, so that the insertion of the seepage pipe 100 is guided by the two rollers 820. In actual operation, the gravity of the seepage pipe 100 is used to make the seepage pipe 100 automatically sink into the mine filling slurry. An electric hoist 830 is also installed on the frame 210. The electric hoist 830 is equipped with a chain 850 and a The hook at the free end of the chain is used to install a pipe clamp 840 on the upper part of the seepage pipe 100, and the hook of the electric hoist 830 is connected to the pipe clamp 840. When the seepage pipe 100 needs to be pulled out, the electric hoist 830 is started, and the electric hoist 830 drags the hook to pull the seepage pipe 100 out of the mine filling slurry. In addition, a bottom wheel 860 for the seepage pipe 100 to rely on is also installed on the frame 810. Specifically, the bottom wheel 860 is rotatably mounted on the frame 810 and is located below the two above-mentioned rollers 820. The seepage pipe 100 passes through the guide gap between the two rollers 820 and then relies on the above-mentioned bottom wheel 860, so as to better guide the insertion and removal of the seepage pipe 100.

[0059] The moisture in the mine filling slurry passes through the water screening channel of the seepage pipe 100 and enters the interior of the seepage pipe 100. The siphon device 300 is used for suction, so as to extract the moisture in the seepage pipe 100 and form a negative pressure in the seepage pipe 100, thereby allowing the moisture in the mine filling slurry to flow into the seepage pipe 100 more smoothly. The negative pressure in the seepage pipe 100 can make the moisture in the mine filling slurry be sucked more thoroughly. After the moisture at a certain position is reduced to an appropriate value, the seepage pipe 100 is inserted into the mine filling slurry at other positions, thereby dehydrating the mine filling slurry at other positions. It is simple and convenient to use.

[0060] Through the above structure, the auxiliary mine filling slurry dehydration system can quickly and effectively remove moisture from the mine filling slurry, so that the mine filling slurry can harden more quickly and ensure the filling quality. Moreover, the dehydration system has a simple structure, and the manufacturing cost and use cost are very low, and it is more economical. In addition, the dehydration system can also be used for dehydration of mine filling slurries of different concentrations. It is flexible and convenient to use, and can be reused. It is highly practical and can be filled and sucked at any time according to the on-site filling plan. Most filling plans are layered filling. The seepage system can also realize layered pumping. Excess water can be extracted before the initial setting of the filling slurry to ensure that the setting time and strength of the filling body will not be affected by the seepage pipe. It should be noted that the above-mentioned stratified pumping can be understood as corresponding to the actual filling situation on site. Specifically, the actual filling is stratified filling. For example, the area at a certain height at the bottom is filled first, and the seepage system is used to pump water immediately after filling. After reaching the appropriate concentration, the seepage pipe 100 is drawn out, and then the upper part of the area is filled, and then the seepage system is used to pump water, and the slurry filling and pumping are completed in sequence.

[0061] In this embodiment, the mother pipe 200 is a pipe made of hard material, and both ends of the mother pipe 200 are closed. A first connecting pipe 400 is fixedly provided in the middle of the pipe wall on one side of the mother pipe 200 by welding or integral molding. The siphon device 300 is connected to the first connecting pipe 400, so that the siphon device 300 is connected to the mother pipe 200 through the first connecting pipe 400. A plurality of second connecting pipes 500 are connected to the pipe wall on the other side of the mother pipe 200. Specifically, the second connecting pipe 500 includes a hard pipe 510 and a pipeline pump 520 connected to the hard pipe 510. The hard pipe 510 is connected between the mother pipe 200 and the seepage pipe 100. In this way, the pipeline pump 520 can be used to assist suction so as to extract water from deeper slurry. It should be noted that the intubation and extraction device 800 is connected to the hard pipe 510.

[0062] Optionally, the siphon device 300 includes a water tank 310, a water pump 320, a first circulating water pipe 330, a second circulating water pipe 340, a circulating box 350, a third circulating water pipe 360 ​​and a branch pipe 370, wherein:

[0063] The top of the water tank 310 is sealed with a top cover, so that the internal space of the water tank 310 forms a closed chamber. A water inlet is opened on the top of the box to allow water to enter the internal space of the water tank 310. A third connecting pipe 600 is connected to the upper side wall of the water tank 310. The third connecting pipe 600 is used to connect to a drain pipe. When the water in the water tank 310 accumulates to a certain height and reaches the pipe mouth of the third connecting pipe 600, the water in the water tank flows away from the third connecting pipe 600 and the drain pipe.

[0064] The water pump 320 is installed outside the water tank 310, and the water inlet of the water pump 320 is connected to the lower part of the water tank 310 through the first circulating water pipe 330, and the second circulating water pipe 340 is connected to the water outlet of the water pump 320. The circulating box 350 is placed at the water inlet of the water tank 310, and the free end of the second circulating water pipe 340 is inserted into the inside of the circulating box 350 from top to bottom, and the second circulating water pipe 340 is welded and fixed to the circulating box 350. A third circulating water pipe 360 ​​is connected and arranged at the bottom of the circulating box 350, and the third circulating water pipe 360 ​​is inserted into the water tank 310 and extends below the first circulating water pipe 330.

[0065] The branch pipe 370 is disposed on the side wall of the circulation box 350 , and is located above the free end of the second circulation water pipe 340 . The branch pipe 370 is connected to and communicates with the main pipe 200 through the first connecting pipe 400 .

[0066] When in use, a certain amount of water is first injected into the water tank 310 so that the water submerges the pipe opening of the first circulating water pipe 330 and the free end of the third circulating water pipe 360. Then, the water pump 320 is started. The water pump 320 pumps the water in the water tank 310 through the first circulating water pipe 330 and injects the water into the second circulating water pipe 340. The second circulating water pipe 340 then flushes the water into the middle and lower position of the circulating box 350. Part of the water accumulates in the middle and lower position of the circulating box 350 and submerges the second circulating water pipe 340. From the end, most of the water will flow out of the third circulating water pipe 360 ​​and eventually flow back into the water tank 310. Since the free end of the third circulating water pipe 360 ​​is located below the first circulating water pipe 330, the water flowing back into the water tank 310 can submerge the free end of the third circulating water pipe 360. In this way, a relatively closed loop water circuit can be formed in the water tank 310, the water pump 320, the first circulating water pipe 330, the second circulating water pipe 340, the circulation box 350 and the third circulating water pipe 360.

[0067] Since the branch pipe 370 is located above the free end of the second circulating water pipe 340, and water directly rushes from the free end of the second circulating water pipe 340 to the lower part of the circulating box 350, the water in the circulating box 350 will not reach the pipe mouth of the branch pipe 370, so the water will not enter the branch pipe 370. When the water in the circulating box 350 flows away from the third circulating water pipe 360 ​​at a certain flow rate, a negative pressure will be formed in the middle and upper space inside the circulating box 360. The branch pipe 370 is connected to the middle and upper part of the circulating box 350. Therefore, the branch pipe 370 0, and negative pressure will also be formed in the first connecting pipe 400 connected to the branch pipe 370 and the main pipe 200, thereby forming a negative pressure in the seepage pipe 100. When the seepage pipe 100 is inserted into the mine filling slurry, the negative pressure will cause the moisture of the mine filling slurry to automatically enter the seepage pipe 100, and in turn pass through the seepage pipe 100, the second connecting pipe 500, the main pipe 200 and the first connecting pipe 400 to pump the water to the branch pipe 370 and the inside of the above-mentioned circulation box 350, and finally flow into the water tank 310 from the third circulating water pipe 360.

[0068] In this way, the siphon device forms negative pressure in the middle and upper space of the circulation box 350 by means of the high-speed flowing water at the bottom of the circulation box 350, and draws moisture from the mine filling slurry by means of the siphon principle. It can be applied to mine filling slurries of different concentrations and is highly practical.

[0069] Optionally, in order to prevent water from entering the branch pipe 370 from the circulation box 350, a one-way valve (not shown) that only allows water to flow back to the circulation box 350 can be installed in the branch pipe 370. Of course, when the water volume is controlled so that the water level in the circulation box 350 does not reach the outlet of the branch pipe 370, the one-way valve does not need to be installed in this case.

[0070] In order to ensure that water can flow smoothly from the third circulating water pipe 360, the bottom of the circulation box 350 in this embodiment is configured as a funnel-shaped structure, and the third circulating water pipe 360 ​​is connected to the constricted end of the funnel-shaped structure.

[0071] Preferably, an overflow port 380 is provided on the top of the water tank 310, and when there is a lot of water in the water tank 310, the water can flow out from the overflow port 380. A partition 390 extending to the middle of the water tank 310 is provided between the bottom and the side wall of the water tank 310, and the internal space of the water tank 310 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 by the partition 390. The first circulating water pipe 330 is connected to the lower left chamber, the third circulating water pipe 360 ​​is inserted into the lower right chamber, and the third connecting pipe 600 is provided on the side wall of the upper chamber, so that the free end of the third circulating water pipe 360 ​​can be submerged in water.

[0072] Of course, it also includes a controller and a power supply. The power supply and the water pump 320 of the siphon device 300 are electrically connected to the controller, so that the controller is used to control the operating state of the siphon device 300. The controller can be a circuit board or a chip, etc.

[0073] In order to facilitate the understanding of the amount of water pumped out by the siphon device 300, in this embodiment, a water meter 700 is also installed on the third pipe 600, and the water meter 700 is used to measure the amount of water flowing through the third pipe 600, so that the user can easily know the amount of water pumped out by the siphon device 300, that is, it is convenient for the user to know the amount of water pumped out from the mine filling slurry when the system is in use, and then it is convenient for the user to know the dehydration of the mine filling slurry. Of course, the water meter 700 can also be replaced by a flow sensor. The water meter 700 can be used to measure the amount of water seepage, adjust the layout of the water seepage pipeline according to the amount of water seepage, and turn on and off the entire water seepage device. At the same time, the discharged water is detected to control the amount of fine particles of the cementitious material within 5%. In addition, a water quality monitoring device is also installed in the third pipeline 600 to monitor the water quality of the water pumped out by the siphon device 300.

[0074] Preferably, there are two siphon devices 300 in this embodiment, and both siphon devices 300 are connected to the mother pipe 200. Specifically, a three-way solenoid valve is installed at one end of the first connecting pipe 400 away from the mother pipe 200. The two siphon devices 300 are connected to the mother pipe 200 through the three-way solenoid valve, and the three-way solenoid valve is also electrically connected to the controller, so that the controller is used to control the working state of the three-way solenoid valve. The two siphon devices 300 are operated one by one, that is, at the same time, only one siphon device 300 is operated and the other siphon device 300 is stopped for standby.

[0075] An optional implementation of this embodiment is as follows: the above-mentioned water seepage pipe 100 includes an inner layer pipe 110, an outer layer pipe 140 and a filter screen 160, wherein:

[0076] A plurality of through holes 111 are provided on the wall of the inner tube 110 so that water can enter the inner tube 110. Both ends of the inner tube 110 are provided with connection structures, which are used to connect the plug 120 or the pipe joint 130. When both ends of the inner tube 110 are connected to the pipe joint 130, multiple different inner tubes 110 can be spliced ​​to extend the length of the whole seepage pipe 100; when one end of the inner tube 110 is connected to the pipe joint 130 and the other end is connected to the plug 120, the plug 120 can block the pipe opening of one end of the inner tube 110, and the connected pipe joint 130 can be used to splice the remaining inner tubes 110 or connect the hard tube 510 of the second connecting pipe 500.

[0077] The outer tube 140 is sleeved outside the inner tube 110 and locked by the locking assembly 150. The outer tube 140 is provided with a plurality of water inlet holes 142, which correspond to the plurality of through holes 111. The filter 160 is installed between the inner tube 110 and the outer tube 140. The filter 160 is used to prevent large particles of impurities from entering the through holes 111. The water inlet holes 142, the mesh of the filter 160 and the through holes 111 constitute the water screening channel.

[0078] When in use, a plug 120 can be connected to one end of the inner tube 110, so that one end of the inner tube 110 is sealed with the plug 120 to prevent air leakage. At the same time, a pipe joint 130 is connected to the other end of the inner tube 110, and then the hard tube 510 of the second connecting tube 500 is connected through the pipe joint 130, so that the seepage pipe 100 is connected to the above-mentioned mother pipe 200 and the siphon device 300. In this case, the seepage pipe 100 can be directly inserted into the mine filling slurry, and the above-mentioned plug 120 needs to penetrate into the slurry; the pipe joints 130 can also be connected to both ends of the inner tube 110. In this case, the inner tube 110 can be used for splicing to extend the length of the seepage pipe 100. In both of the above situations, the seepage pipe 100 is inserted into the mine filling slurry, and the water in the slurry passes through the water inlet hole 142, the filter screen 160 and the through hole 111 in turn and enters the inner tube 110. With the help of the siphon device 300, the speed of water entering the inner tube 110 can be further accelerated and the water in the inner tube 110 can be pumped out. The above-mentioned siphon device 300 is used to drain the water in the inner tube 110, thereby helping to dehydrate the mine filling slurry. The setting of the filter screen 160 can prevent the particles in the slurry from entering the inner tube 110, which can reduce the chance of blockage of the inner tube 110.

[0079] When the seepage pipe 100 is used in conjunction with the siphon device 300 and the mother pipe 200, it can be used to absorb and remove the moisture in the mine filling slurry. It has a high dehydration rate and can be applied to mine filling slurries of different concentrations, thereby accelerating the drying and curing efficiency of the slurry. The seepage pipe 100 has the advantages of simple structure, low manufacturing cost and low use cost. It is also convenient to carry anywhere, flexible to use, and repeatedly used, and practical. It should be noted that the "dehydration of the mining site" described in this embodiment refers to dehydration at the mining site.

The third through hole penetrates the inner tube 110 along the radial direction of the inner tube 110. The screw 151 is connected to the first through hole, the second through hole and the third through hole, and both ends of the screw 151 extend out of the outer tube 140. Two nuts 152 are screwed to the screw 151, and the two nuts 152 are respectively located on both sides of the outer tube 140, and the two nuts 152 press the two half-tubes 141 of the outer tube 140 onto the filter screen 160. When the nut 152 is tightened, the locking assembly 150 is locked, and when the nut 152 is loosened and removed, the locking assembly 150 is unlocked.

[0082] Of course, the locking assembly 150 may also be a strap, which is used to tightly tie the two half pipes 141 .
