Description

Technical Field

[0001] The present invention relates to the technical field of coal mine water gushing treatment, and in particular to a coal mine underground water gushing treatment device and treatment method. Background Art

[0002] Coal mining operations require prompt treatment of water inrush to prevent it from flooding tunnels or working faces, potentially impacting mining progress, damaging underground equipment, and even causing major safety risks such as well flooding. The typical treatment for water inrush in coal mines involves extracting the water through the mine's internal pumping system, purifying it, and then discharging the treated water into natural water bodies or for industrial reuse.

[0003] In the related technology, chemical reagents need to be added to the coal mine water to achieve purification. However, if the required chemical reagents are added to the water at the same time, agglomeration is likely to occur, and adding chemical reagents at different times will increase the labor intensity and affect the efficiency of coal mine water treatment. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, an embodiment of one aspect of the present invention proposes a coal mine underground water gushing treatment device, which can realize automatic time-sharing addition of chemical reagents to the reaction pool, reduce manual labor intensity, avoid the agglomeration of chemical reagents in the gushing water, and ensure the efficiency of coal mine water gushing treatment.

[0006] Another embodiment of the present invention provides a method for treating water inrush in an underground coal mine.

[0007] According to an embodiment of the present invention, a coal mine underground water gushing treatment device includes a graded purification component and a feeding component, the graded purification component includes a reaction tank, the reaction tank is provided with a dosing port and is used to purify gushing water; the feeding component includes a medicine storage tank, a movable disk and a motor, the medicine storage tank is provided with a medicine outlet, the movable disk is rotatably connected to the medicine storage tank and covers the medicine outlet, the movable disk is provided with a dosing port connected to the medicine outlet, the dosing port has a first position connected to the dosing port and a second position disconnected from the dosing port, the motor is transmission-connected to the movable disk to enable the dosing port to switch between the first position and the second position.

[0008] According to the coal mine underground water treatment device of the embodiment of the present invention, the reaction tank can purify the water in the water. In particular, because the motor is connected to the movable disk, the motor can drive the movable disk to rotate, so that the drug injection port on the movable disk rotates accordingly, thereby realizing automatic switching of the drug injection port between the first position and the second position, that is, the drug injection port and the drug addition port are switched between a connected or disconnected state. When the drug injection port is in the first position, the chemical reagents in the drug storage tank can be sequentially added to the reaction tank through the drug outlet, the drug injection port and the drug addition port, thereby removing harmful substances (including heavy metal ions, etc.) in the water in the reaction tank. When the dosing port is in the second position, the dosing port is disconnected from the dosing port, and the chemical reagents in the medicine storage tank cannot enter the reaction tank through the medicine outlet. The gushing water in the reaction tank can fully react with the chemical reagents that have been added, effectively avoiding the problem of chemical reagent agglomeration that is prone to occur during continuous dosing. At the same time, the coordinated structure of the motor and the movable disk can realize the timed and quantitative addition of chemical reagents without manual operation.

[0049] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0050] like Figures 1 to 6As shown, an underground coal mine water gushing treatment device according to an embodiment of the present invention includes a graded purification component 1 and a feeding component 2. The graded purification component 1 includes a reaction tank 11, which is provided with a dosing port 111 and is used to purify gushing water; the feeding component 2 includes a medicine storage tank 21, a movable disk 22 and a motor 23. The medicine storage tank 21 is provided with a medicine outlet 211, the movable disk 22 is rotatably connected to the medicine storage tank 21 and covers the medicine outlet 211, the movable disk 22 is provided with a medicine feeding port 221 connected to the medicine outlet 211, the medicine feeding port 221 has a first position connected to the dosing port 111 and a second position disconnected from the dosing port 111, and the motor 23 is transmission-connected to the movable disk 22 to switch the medicine feeding port 221 between the first position and the second position.

[0051] According to the coal mine underground water treatment device of the embodiment of the present invention, the reaction tank 11 can purify the water, wherein, because the motor 23 is connected to the movable disk 22 by transmission, the motor 23 can drive the movable disk 22 to rotate, so that the dosing port 221 on the movable disk 22 rotates accordingly, thereby realizing the automatic switching of the dosing port 221 between the first position and the second position, that is, the dosing port 221 and the dosing port 111 are switched between the connected or disconnected state, so that when the dosing port 221 is in the first position, the chemical reagent of the drug storage tank 21 can be sequentially added to the reaction tank 11 through the drug outlet 211, the dosing port 221 and the dosing port 111 to remove the harmful substances (including Including heavy metal ions, etc.), and when the dosing port 221 is in the second position, the dosing port 221 is disconnected from the dosing port 111, and the chemical reagents in the storage tank 21 cannot enter the reaction tank 11 through the discharge port 211. The gushing water in the reaction tank 11 can fully react with the chemical reagents that have been put in, effectively avoiding the problem of chemical reagent agglomeration that is prone to occur due to continuous dosing. At the same time, the coordinated structure of the motor 23 and the movable disk 22 can realize the timed and quantitative dosing of chemical reagents without manual operation. Therefore, compared with the related art, the present invention can realize automatic time-sharing dosing of chemical reagents into the reaction tank 11, reduces manual labor intensity, avoids the agglomeration of chemical reagents in the gushing water, and ensures the efficiency of coal mine water treatment.

[0052] Specifically, the direction of the pivot axis of the movable disk 22 is consistent with the extension direction of the medicine storage tank 21 .

[0053] It should be noted that coal mine water inrush is the phenomenon in which groundwater or surface water flows into mine tunnels, mining working faces and other spaces during coal mining. The main reason for its formation is that coal mining destroys the original aquiclude of the stratum and the balance of the groundwater system, causing water to enter the mine along mining cracks, faults, aquifers, etc.

[0054] like Figure 1 and Figure 2As shown, in some embodiments, the graded purification component 1 further includes a primary sedimentation tank 12, a secondary sedimentation tank 13 and a discharge tank 14. The primary sedimentation tank 12, the secondary sedimentation tank 13, the reaction tank 11 and the discharge tank 14 are connected in sequence. The primary sedimentation tank 12 is provided with a first inlet 121 suitable for introducing gushing water, and the discharge tank 14 is provided with a discharge port 141 to discharge the purified gushing water.

[0055] It can be understood that a graded purification treatment system for gushing water is constructed by cooperating with the primary sedimentation tank 12, the secondary sedimentation tank 13, the reaction tank 11 and the discharge tank 14. Among them, the primary sedimentation tank 12 and the secondary sedimentation tank 13 can realize two-stage sedimentation treatment of the gushing water, which reduces the purification treatment pressure of the reaction tank 11 on the gushing water to a certain extent and improves the purification efficiency. The discharge tank 14 can temporarily store the purified gushing water, which can facilitate technical personnel to inspect the purified gushing water and discharge it through the discharge port 141 after determining that the purified gushing water is qualified (that is, meets the discharge standards). Otherwise, the purified gushing water will be subjected to corresponding treatment.

[0056] Specifically, the primary sedimentation tank 12 and the secondary sedimentation tank 13 can be connected via a first flow conduit 15, the secondary sedimentation tank 13 and the reaction tank 11 can be connected via a second flow conduit 16, and the reaction tank 11 and the discharge tank 14 can be connected via a third flow conduit 17. Each of the first flow conduit 15, the second flow conduit 16, and the third flow conduit 17 can be equipped with a one-way valve (not shown) to ensure unidirectional flow of gushing water and prevent backflow. The discharge port 141 can be connected to the external environment or external equipment via the discharge conduit.

[0057] In addition, the first guide pipe 15, the second guide pipe 16, the third guide pipe 17 and the discharge pipe may be provided with control valves (not shown in the figure) to control the water flow rate to ensure the normal operation of the entire graded purification system.

[0058] For example, taking the figure as an example, the primary sedimentation tank 12, the secondary sedimentation tank 13, the reaction tank 11 and the discharge tank 14 can be arranged in a horizontal direction, wherein the primary sedimentation tank 12 and the secondary sedimentation tank 13 can be arranged adjacent to each other along the first direction, the reaction tank 11 and the discharge tank 14 can be arranged adjacent to each other along the first direction, and the secondary sedimentation tank 13 and the reaction tank 11 can be arranged adjacent to each other along the second direction, and the primary sedimentation tank 12 and the discharge tank 14 can be arranged adjacent to each other along the second direction. The first direction, the second direction and the up and down directions are perpendicular to each other, so as to shorten the flow path of the gushing water in the entire graded purification treatment system, which is conducive to improving the gushing water treatment efficiency and high integration.

[0059] like Figures 1 to 4 As shown, in some embodiments, the secondary sedimentation tank 13 is provided with a second inlet 131 , and the processing device further includes a diversion well 3 and a filter screen 4 .

[0060] Among them, the diversion well 3 has a accommodating chamber 31 and is provided with an injection port 32, a first outlet 33 and a second outlet 34 connected to the accommodating chamber 31. The injection port 32 is suitable for connecting with the coal mine pumping system to allow the extracted water to be injected into the accommodating chamber 31. The first outlet 33 is connected to the first inlet 121, and the second outlet 34 is connected to the second inlet 131.

[0061] The filter screen 4 is disposed in the accommodating chamber 31 and divides the accommodating chamber 31 into a first chamber 311 and a second chamber 312 . The first chamber 311 is connected to the injection port 32 and the first outlet 33 , and the second chamber 312 is connected to the second outlet 34 .

[0062] It can be understood that the diversion component is formed by the diversion well 3 and the filter screen 4 structure, which can enable the gushing water extracted by the coal mine pumping system to be injected into the accommodating chamber 31 and then be divided into two parts to enter the graded purification treatment system for treatment. Among them, a part of the gushing water containing mud, sand and ore entering the first chamber 311 from the injection port 32 can be directly injected into the primary sedimentation tank 12 for precipitation through the first outlet 33 and the first inlet 121, while the other part of the gushing water entering the first chamber 311 will first be preliminarily filtered by the filter screen 4, and then enter the second chamber 312 and be injected into the secondary sedimentation tank 13 for precipitation through the second outlet 34 and the second inlet 131. The above-mentioned method of diverting the gushing water, on the one hand, reduces the subsequent purification burden, and on the other hand, can improve the subsequent sedimentation effect.

[0063] Specifically, the first outlet 33 can be connected to the first inlet 121 via a first shunt pipe, and the second outlet 34 can be connected to the second inlet 131 via a second shunt pipe. The filter 4 can be detachably connected to the accommodating chamber 31 to facilitate subsequent disassembly and maintenance of the filter 4, thereby saving costs to a certain extent. The first outlet 33 and the second outlet 34 are respectively provided on either side of the filter 4.

[0064] Furthermore, the top of the accommodating chamber 31 is open, and the diversion well 3 includes a well body 35 and a well cover 36. The well body 35 has an accommodating chamber 31 and is provided with a first outlet 33 and a second outlet 34; the well cover 36 is arranged on the top of the well body 35 to seal the top opening of the accommodating chamber 31, and the well cover 36 is provided with an injection port 32.

[0065] Specifically, the well 35 and the accommodating chamber 31 may both extend vertically. The filter screen 4 may also extend vertically. The first chamber 311 and the second chamber 312 may be arranged horizontally and extend vertically. The first outlet 33 may be provided on the bottom wall of the well 35. The second outlet 34 may be provided on the side wall of the well 35.

[0066] like Figures 1 to 5 As shown, in some embodiments, the graded purification assembly 1 further includes a cover plate 5 , which is disposed on the top of the reaction tank 11 to seal the reaction tank 11 .

[0067] The cover plate 5 includes a mounting portion 51 and an opening and closing portion 52. The mounting portion 51 is located in the middle of the top of the reaction tank 11. The medicine storage tank 21 and the motor 23 are both arranged on the mounting portion 51. The mounting portion 51 is provided with a dosing port 111. There are two opening and closing portions 52 and they are arranged on both sides of the mounting portion 51 along the horizontal direction. The opening and closing portion 52 is rotatably connected to the top of the reaction tank 11.

[0068] It can be understood that the cover plate 5 can seal the reaction pool 11 to ensure the reaction environment inside the reaction pool 11, reduce interference from external factors, and ensure the purification effect of the gushing water. Among them, the mounting portion 51 is used to support the medicine storage tank 21 and the motor 23 on the reaction pool 11, and the opening and closing portion 52 can open or close the reaction pool 11, so that the inside of the reaction pool 11 can be cleaned or maintained by opening the opening and closing portion 52 at a later time.

[0069] Specifically, the mounting portion 51 can be fixed on the top of the reaction cell 11 . The drug storage tank 21 and the motor 23 can both be mounted above the mounting portion 51 .

[0070] like Figure 6 As shown, in some embodiments, the medicine storage tank 21 includes a tank body 212 and a tank cover 213, the bottom of the tank body 212 is provided with a medicine outlet 211, and the tank cover 213 is detachably connected to the top of the tank body 212, such as, the top of the tank body 212 is threadedly connected to the tank cover 213 to achieve reliable installation of the tank cover 213 on the tank body 212.

[0071] It is understandable that the drug storage tank 21 is designed as a separate structure of the tank body 212 and the tank cover 213. The purification chemical reagent can be added into the tank body 212 by opening the tank cover 213, which is conducive to the convenient addition of the chemical reagent.

[0072] Specifically, the tank body 212 can extend in the vertical direction. A movable disk 22 is pivotally mounted on the bottom of the tank body 212, with the pivot axis of the movable disk 22 aligned with the extension direction of the tank body 212. To reduce the impact of the external environment on the chemical reagent, a sealing structure, such as a sealing ring, can be provided on the tank cover 213 to ensure that the tank cover 213 is sealed to the tank body 212.

[0073] like Figure 5 and Figure 6 As shown, in some embodiments, there are multiple drug injection ports 221 and they are arranged at intervals along the circumference of the movable disk 22 (not shown in the figure), and there are multiple drug addition ports 111 and they correspond one-to-one to the drug injection ports 221.

[0074] It is understandable that by using multiple drug injection ports 221 and multiple drug injection ports 111 , chemical reagents can be dispersedly injected into the reaction tank 11 , thereby improving the purification effect of the water in the reaction tank 11 .

[0075] Furthermore, the plurality of dosing ports 221 may be arranged at equal intervals along the circumference of the movable disk 22 to further improve the dosing uniformity of the chemical reagents and ensure the purification performance of the gushing water.

[0076] like Figure 5 and Figure 6 As shown, in some embodiments, the feeding assembly 2 further includes a driving disc 24 and a shifting rod 25 , the motor 23 is transmission-connected to the driving disc 24 , and the driving disc 24 is provided with a shifting rod 25 .

[0077] A protrusion 222 is provided at one end of the movable disk 22 away from the medicine outlet 211 and has a stationary state and a moving state. There are multiple protrusions 222 and they are arranged at equal intervals along the circumference of the movable disk 22. A groove 26 is defined between any two adjacent protrusions 222. In the stationary state, the lever 25 is separated from the groove 26, and the medicine feeding port 221 is in the first position and connected to the medicine adding port 111. In the moving state, the lever 25 slides with the groove 26, and the medicine feeding port 221 is in the second position and disconnected from the medicine adding port 111.

[0078] It can be understood that an intermittent transmission mechanism is formed by cooperating with the driving disk 24, the lever 25 and the movable disk 22, so that when the motor 23 drives the driving disk 24 to rotate, the lever 25 cooperates with the groove 26 to enable the movable disk 22 to switch between a stationary state and a moving state, that is, when the movable disk 22 is in a stationary state, the dosing port 221 can be connected to the dosing port 111 to doze the reaction tank 11, and when the movable disk 22 is in a moving state, the dosing port 221 is disconnected from the dosing port 111 to provide time for the gushing water to react with the chemical reagent, thereby avoiding the risk of agglomeration caused by continuous dosing of the chemical reagent. Therefore, by adopting the above-mentioned structure, the chemical reagent can be intermittently added to the reaction tank 11 in a timely and quantitative manner without manual operation, thereby ensuring the treatment efficiency of the coal mine water.

[0079] Specifically, the movable disk 22 is located at the bottom of the tank body 212 , and a protrusion 222 is provided at the bottom of the movable disk 22 .

[0080] like Figures 6 to 8 As shown, in some embodiments, the processing device also includes a stirring rod 6 and a dispersion disk 7. The stirring rod 6 is connected to the motor 23 for transmission, and at least a portion of the stirring rod 6 is located in the reaction tank 11; the dispersion disk 7 is connected to the stirring rod 6 and is located in the reaction tank 11 to fully mix the chemical reagents and the gushing water.

[0081] It can be understood that the stirring rod 6 and the dispersion disk 7 cooperate to form a mixing assembly, and the stirring rod 6 is driven by the motor 23 to rotate, so that the dispersion disk 7 rotates accordingly, so that the chemical reagents and the gushing water can be fully mixed, the purification reaction efficiency is improved, and the chemical reagents are further prevented from agglomerating and sticking. At the same time, the stirring rod 6 and the drive disk 24 are driven by the same motor 23, which can reduce the number of parts, improve the structural compactness of the treatment device, and reduce costs.

[0082] Specifically, the stirring rod 6 may extend in the up-down direction. The dispersion plate 7 may be provided at the bottom of the stirring rod 6 .

[0083] In combination with the above structure, such as in the figure, the motor 23 can be located next to the medicine storage tank 21. The motor shaft output end of the motor 23 can be connected to the top of the stirring rod 6, and the motor shaft output end of the motor 23 can also be sleeved with a first pulley 231. A second pulley 232 and a drive disk 24 can be further provided between the motor 23 and the medicine storage tank 21. The second pulley 232 and the drive disk 24 can be rotatably mounted above the mounting portion 51 of the cover plate 5 via the same rotating shaft. The first pulley 231 and the second pulley 232 can be connected via a belt drive to achieve simultaneous control of the feeding assembly 2 and the mixing assembly by the motor 23.

[0084] In addition, the feeding assembly 2 may also include a protective shell 27, which is arranged on the outside of each of the movable disk 22, the second pulley 232 and the driving disk 24, and the protective shell 27 is located between the medicine outlet 211 of the medicine storage tank 21 and the mounting portion 51 of the cover plate 5 in the up and down directions.

[0085] Therefore, compared with the related art, the present invention can realize the preliminary separation and diversion of solid and liquid in the gushing water through the diversion component, and the graded purification component 1 improves the purification efficiency and reduces the processing load through multi-stage precipitation and reaction.
