Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically to a mine water pretreatment and reinjection equipment. Background Technology

[0002] Mine water pretreatment and reinjection equipment is used to purify mine water and reinject the treated water back underground.

[0003] In the pretreatment process of mine water reinjection, flocculation and sedimentation are the core and key steps for removing suspended solids, colloids and other impurities from the water. Existing mine water treatment equipment generally adopts the process of "adding reagents - stirring and mixing - settling - stopping and cleaning" for this step.

[0004] After the mine water is allowed to settle, the flocculated impurities formed by flocculation accumulate at the bottom of the treatment tank. The entire equipment then needs to be stopped, and the impurities are removed manually by opening the valve at the bottom of the tank, using a suction device, or by manual shoveling. This shutdown and cleaning process typically takes time, directly reducing the equipment's daily effective operating time and thus lowering the mine water treatment efficiency.

[0005] During shutdown for slag removal, the lack of efficient methods for collecting sediment (such as manual shoveling and slow conventional suction) significantly increases the total time required for each slag removal operation. In addition to the basic time for drainage and opening the cover, the impurity collection process alone further extends the shutdown process, thereby compressing the effective operating time of the equipment and further reducing the efficiency of mine water treatment. If sediment cannot be collected quickly, some impurities that are not cleaned in time will accumulate at the bottom of the tank for a long time, which may not only harden and clump, but also block the slag removal valves, pipelines and subsequent equipment interfaces, making the next slag removal more difficult and time-consuming.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing mine water pretreatment and reinjection equipment. Summary of the Invention

[0007] The technical solution of this invention addresses the problem that existing technical solutions are too simplistic, and provides a solution that is significantly different from existing technologies. Specifically, the purpose of this invention is to provide a mine water pretreatment and reinjection device to solve the problems mentioned in the background technology, such as reduced mine water treatment efficiency due to shutdown for slag removal, slow sediment collection, and easy accumulation and hardening of sediment at the bottom of the tank, which can clog valves and pipelines, thereby increasing the difficulty of slag removal and operation and maintenance costs.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a mine water pretreatment and reinjection device, comprising a treatment tank body, an inlet pipe disposed at the top of the treatment tank body, an electrically controlled two-way valve body connected to one end of the inlet pipe, an electrically controlled valve body disposed at the bottom of the outer wall of the treatment tank body, and further comprising: A sedimentation and slag discharge mechanism is installed at the bottom of the processing tank body; A collection mechanism is installed at the bottom of the sedimentation and slag discharge mechanism; The sedimentation and slag discharge mechanism includes a conveyor belt located at the bottom of the treatment tank body, and a filter screen is provided on the inner wall of the conveyor belt.

[0010] Preferably, a telescopic rod is provided on the top of the sealing block, and a spring is provided around the outer wall of the telescopic rod; The processing tank body has two symmetrically arranged units. The exterior of the processing tank body is rectangular. The interior of the processing tank is a hollow cylinder.

[0011] Preferably, the outer wall of the conveyor belt is open; Sealing rings are provided on both sides of the outer wall of the conveyor belt.

[0012] Preferably, a groove is formed at the bottom of the processing tank body cavity; The diameter of the processing tank body is matched to the sum of the diameters of the conveyor belt and the sealing ring.

[0013] Preferably, the three-dimensional view of the sealing block is an irregular cuboid; The outer wall of the sealing block is inclined; The shape of the sealing block is adapted to the shape of the opening on the outer wall of the conveyor belt.

[0014] Preferably, the water turbine is aligned with the electrically controlled valve body located at the bottom of the outer wall of the treatment tank. One end of the load-bearing plate is semi-circular.

[0015] Preferably, the conveyor belt passes through a groove opened at the bottom of the processing tank body cavity; The conveyor belt is equipped with a drive device and a support frame; the water wheel is connected to the support frame on the outside of the conveyor belt via a connecting assembly. The bottom of the water turbine is aligned with one side of the drainage chamber; Two conveyor belts are symmetrically arranged. Both ends of the collection bin are located at the bottom of both ends of the conveyor belt.

[0016] Preferably, it also includes a fine filtration recharge mechanism located at the front of the collection chamber; The fine filtration and recharge mechanism includes a water pump located at the front of the drainage chamber, the output end of the water pump is connected to a connecting pipe, and one end of the connecting pipe is connected to a filter chamber. One end of the conveyor belt drive device is movably connected to a drive bevel gear.

[0017] Preferably, a driven bevel gear is movably disposed on the top of the driving bevel gear, and the driving bevel gear and the driven bevel gear form a meshing transmission connection; The driven bevel gear is movably connected to the top of the driven bevel gear, and a belt is connected around the outer wall of the driven bevel gear. One end of the belt is connected to the driven bevel gear. A rotating rod is movably connected to the bottom of the driven wheel; The inner wall of the filter chamber is provided with an annular filter screen, and scrapers are distributed around the outer wall of the rotating rod; A drain pipe is connected to one side of the outer wall of the filter chamber; A slag discharge bin is provided at the bottom of the filter chamber.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up dual treatment tanks, an electrically controlled bidirectional valve, and a sedimentation and slag discharge mechanism, a continuous pretreatment process of "alternating operation of dual tanks + synchronous slag removal" is formed. This solves the problem of limited effective operating time caused by shutdown for slag removal. Traditional equipment is limited by the single-tank treatment mode, requiring an interruption of the entire operation process during the slag removal stage, making it difficult to match the actual working conditions of continuous mine water discharge. In contrast, the symmetrical arrangement of the dual treatment tanks in this invention, combined with the switching control of the electrically controlled bidirectional valve, allows the other tank to simultaneously carry out pretreatment processes such as water intake and reagent mixing while sedimentation is being performed on one side. After sedimentation is complete... Once completed, the system only needs to drain water through the electrically controlled valve and start the conveyor belt of the sedimentation and slag removal mechanism to transport the sediment. There is no need to stop the machine during the entire process. This continuous operation mode not only significantly increases the amount of mine water processed per unit time, but also avoids the risk of process interruption caused by traditional shutdown for slag removal. There is no need to configure additional temporary water storage facilities to receive and process mine water, which significantly reduces the complexity of water resource scheduling in the mining area. At the same time, continuous operation reduces the frequent start-up and shutdown of core components such as mixing equipment and electrically controlled valves, reduces mechanical wear and circuit fatigue losses, extends the overall service life of the equipment, and improves the stability and reliability of system operation.

[0019] 2. By incorporating a sedimentation and slag removal mechanism and a collection mechanism, the rapid and targeted collection and residue-free cleaning of sediment are achieved, solving the problems of slow sediment collection speed and easy residue accumulation. This significantly reduces operation and maintenance costs and safety risks. Compared to the limitations of traditional slag removal methods that rely on manual operation, the sediment in this invention can fall directly onto a conveyor belt for collection. The conveyor belt quickly transports the sediment to the collection bin. Combined with the low-frequency vibration generated by the water flow driving the water wheel and the impact plate colliding with the conveyor belt during drainage, residual sediment can be thoroughly shaken off, ensuring no residue accumulation. At the same time, the sealing block is tightly fitted to the conveyor belt under the action of the telescopic rod and spring, ensuring the sealing of the process and avoiding the risk of water leakage. The entire slag removal process requires no manual intervention, which not only improves sediment collection efficiency but also avoids valve and pipeline blockage caused by impurity accumulation, reducing equipment maintenance frequency and parts replacement costs. It also reduces the operating time of workers in the confined explosion-proof environment underground, avoids the safety hazards that may be faced by manual slag removal, and further improves the safety and economy of equipment operation and maintenance.

[0020] 3. The design, incorporating a water pump, filter chamber, annular filter screen, and scraper (outer wall of the rotating rod), allows for secondary filtration and reinjection of pretreated mine water. This effectively solves the problem of long-term accumulation of fine residues causing pipe blockage during the reinjection process, ensuring the long-term stable operation of the reinjection system. Typically, pretreated mine water is directly reinjected, and residual fine residues easily enter the reinjection pipe with the water flow. Long-term accumulation can reduce pipe diameter, increase transport resistance, and even cause complete pipe blockage, affecting reinjection efficiency and making cleaning difficult. This invention allows the pretreated water to first pass through a drainage chamber... The water enters the filter chamber and undergoes secondary filtration through a ring-shaped filter screen, trapping fine residues. The system automatically scrapes off residues adsorbed on the outer wall of the ring-shaped filter screen and collects them in the discharge chamber. No additional drive equipment is required. This achieves targeted collection and cleaning of residues, preventing filter screen clogging and ensuring the cleanliness of the reinjection water. It reduces the risk of clogging in the reinjection pipeline from the source and extends the pipeline's lifespan. Furthermore, the water after secondary filtration is reinjected through the drainage pipe, further improving the quality of the reinjection water, reducing potential impacts on underground aquifers, and enhancing the compliance and safety of the reinjection operation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 15The present invention provides a technical solution: a mine water pretreatment and reinjection device, comprising a treatment tank body 1, an inlet pipe 4 disposed at the top of the treatment tank body 1, an electrically controlled two-way valve body 5 connected to one end of the inlet pipe 4, and an electrically controlled valve body 6 disposed at the bottom of the outer wall of the treatment tank body 1, and further comprising: The sedimentation and slag discharge mechanism 2 is installed at the bottom of the processing tank body 1; The collection mechanism 3 is located at the bottom of the sedimentation and slag discharge mechanism 2; The sedimentation and slag discharge mechanism 2 includes a conveyor belt 201 located at the bottom of the processing tank body 1, and a filter screen 203 is provided on the inner wall of the conveyor belt 201. The inner wall of the treatment tank body 1 has cavities on both sides; A sealing block 204 is movable inside the cavity of the treatment tank body 1.

[0029] In this embodiment, the arrangement of the dual treatment tank body 1, the electrically controlled bidirectional valve body 5, the electrically controlled valve body 6, and the sedimentation and slag discharge mechanism 2 forms a continuous pretreatment process of "alternating operation of dual tanks + synchronous slag removal," thereby solving the problem of limited effective operating time of the equipment due to shutdown for slag removal. Traditional equipment is limited by the single-tank treatment mode, and the entire operation process needs to be interrupted during the slag removal stage, which is difficult to match the actual working conditions of continuous mine water discharge. However, in this invention, the dual treatment tank bodies 1 are symmetrically arranged, and with the switching control of the electrically controlled bidirectional valve body 5, it is possible to realize that when one treatment tank body 1 is carrying out sedimentation operation, the other side can simultaneously carry out pretreatment processes such as water intake and reagent mixing. After sedimentation is complete, it is only necessary to drain water through the electrically controlled valve body 6 and start the conveyor belt 201 of the sedimentation and slag removal mechanism 2 to transport the sediment. There is no need to stop the machine during the entire process. This continuous operation mode not only greatly increases the amount of mine water processed per unit time, but also avoids the risk of process interruption caused by traditional shutdown for slag removal. There is no need to configure additional temporary water storage facilities to receive and process mine water, which significantly reduces the complexity of water resource scheduling in the mining area. At the same time, continuous operation reduces the frequent start-up and shutdown of core components such as mixing equipment and electrically controlled valves, reduces mechanical wear and circuit fatigue losses, extends the overall service life of the equipment, and improves the stability and reliability of system operation.

[0030] The collection mechanism 3 includes a water wheel 301 located at the bottom of the conveyor belt 201, and force-bearing plates 302 are equidistantly arranged on the outer wall of the water wheel 301; A collection chamber 303 is provided on one side of the water turbine 301; A drainage chamber 304 is provided at the bottom of the collection chamber 303.

[0031] In this embodiment, the sedimentation and slag discharge mechanism 2 and the collection mechanism 3 enable rapid and directional collection and residue-free cleaning of sediment, solving the problems of slow sediment collection speed and easy residue accumulation. This significantly reduces operation and maintenance costs and safety risks. Compared with the limitations of traditional slag removal methods that rely on manual operation, the sediment after sedimentation in this invention can fall directly onto the conveyor belt 201 for collection. The conveyor belt 201 quickly transports the sediment to the collection bin 303. In conjunction with the low-frequency vibration generated by the water flow driving the water wheel 301 to drive the force plate 302 to collide with the conveyor belt 201 during the drainage process, the sediment can be completely shaken off. Residual sediment is eliminated, ensuring no residue buildup. Simultaneously, the sealing block 204, under the action of the telescopic rod 205 and spring 206, tightly adheres to the conveyor belt 201, guaranteeing a tight seal during processing and preventing leakage. The entire slag removal process requires no manual intervention, improving sediment collection efficiency and preventing valve and pipeline blockages caused by impurity accumulation, thus reducing equipment maintenance frequency and parts replacement costs. Furthermore, it reduces the operating time of workers in the confined, explosion-proof environment underground, avoiding potential safety hazards associated with manual slag removal, and further enhancing the safety and economy of equipment operation and maintenance.

[0032] A telescopic rod 205 is provided on the top of the sealing block 204, and a spring 206 is provided around the outer wall of the telescopic rod 205; There are two symmetrically arranged processing tanks 1; The exterior of the processing tank body 1 is rectangular; The interior of the treatment tank body 1 is a hollow cylinder.

[0033] In this embodiment, the electrically controlled bidirectional valve body 5 and the electrically controlled valve body 6 can be started and stopped by electrical control in the prior art. At the same time, the treatment tank body 1 is equipped with a stirring device inside. After starting the device, the user first starts the electrically controlled bidirectional valve body 5 to introduce mine water into the interior of the treatment tank body 1 from one side water inlet pipe 4. After pouring the reagent into the interior of the treatment tank body 1, the stirring device is started to stir. After stirring is completed, sedimentation can be carried out. During the process of introducing mine water, pouring reagent, stirring and sedimentation, the electrically controlled valve body 6 at the bottom of the outer wall of the treatment tank body 1 is in a closed state. When the mine water inside the treatment tank body 1 is set, the user can start the electrically controlled bidirectional valve body 5 to close the one side water inlet pipe 4 and open the other side water inlet pipe 4, and then introduce the mine water into the interior of the other side treatment tank body 1 (the alternating circulation sedimentation formed by the setting of the two treatment tank bodies 1 and the electrically controlled bidirectional valve body 5 can improve the overall pretreatment efficiency of the mine water).

[0034] The outer wall of conveyor belt 201 is open; Sealing rings 202 are provided on both sides of the outer wall of the conveyor belt 201.

[0035] In this embodiment, when the mine water inside the treatment tank 1 settles, the sediment gradually falls onto the outer wall of the conveyor belt 201. The opening of the outer wall of the conveyor belt 201 can fill the sediment into this space. When the treatment tank 1 is settling, the conveyor belt 201 is in a stopped state. After the sedimentation of the treatment tank 1 is completed and the user activates the electrically controlled valve body 6 at the bottom of the outer wall of the treatment tank 1, the conveyor belt 201 can be started by the drive device. At the same time, the direction of rotation of the conveyor belt 201 is towards the treatment tank 1 on the other side. When the conveyor belt 201 is started, the opening of the conveyor belt 201 can transport the sediment out of the tank of the treatment tank 1. When the conveyor belt 201 rotates to the bottom, part of the sediment in the opening of the conveyor belt 201 will fall directly onto the inner wall of the collection chamber 303 due to the influence of gravity.

[0036] A groove is provided at the bottom of the cavity of the processing tank body 1; The diameter of the tank body 1 is matched with the sum of the diameters of the conveyor belt 201 and the sealing ring 202.

[0037] In this embodiment, when the treatment tank body 1 on one side starts to drain water through the electrically controlled valve body 6, the water flow will pass through the conveyor belt 201 and flow onto the force plate 302 set on the outer wall of the water wheel 301. The force plate 302 will be driven to rotate by the impact of the water flow. The rotation directions of the water wheel 301 and the force plate 302 are opposite, but the conveyor belt 201 is electrically driven. Therefore, when the force plate 302 rotates, it will be continuously impacted by the water flow and driven to rotate to the other side by the conveyor belt 201. This causes one end of the force plate 302 to continuously collide with the outer wall of the conveyor belt 201, causing the conveyor belt 201 to vibrate continuously at low frequency, so that the water wheel 301 will vibrate when it is first started.

[0038] The three-dimensional view of sealing block 204 is an irregular cuboid; The outer wall of the sealing block 204 is inclined; The shape of the sealing block 204 is adapted to the shape of the opening on the outer wall of the conveyor belt 201.

[0039] In this embodiment, when mine water is introduced into the treatment tank body 1, the treatment tank body 1 is not sealed because it has a groove and the conveyor belt 201 passes through the groove. To prevent water leakage, sealing rings 202 are provided on both sides of the outer wall of the conveyor belt 201. However, the conveyor belt 201 is also in a water-permeable state, so a sealing block 204 is provided. When the conveyor belt 201 stops, that is, when there is water inside the treatment tank body 1, the sealing block 204 is squeezed by the telescopic rod 205 and the spring 206 and inserted into the opening of the conveyor belt 201. At this time, the sealing block 204 fits against the opening of the conveyor belt 201, thereby making the treatment tank body 1 sealed.

[0040] The water turbine 301 is aligned with the electrically controlled valve body 6 located at the bottom of the outer wall of the treatment tank body 1; One end of the load-bearing plate 302 is semi-circular.

[0041] In this embodiment, when the conveyor belt 201 stops, i.e., when there is water inside the treatment tank body 1, the sealing block 204 is squeezed by the telescopic rod 205 and the spring 206 and inserted into the opening of the conveyor belt 201. At this time, the sealing block 204 fits against the opening of the conveyor belt 201, thereby forming a sealed state for the treatment tank body 1. When the conveyor belt 201 is running, the sealing block 204 is squeezed upward and moves upward. When it passes the next opening of the conveyor belt 201, it will be reinserted into the opening of the conveyor belt 201, forming an intermittent rapid sealing state.

[0042] The conveyor belt 201 passes through the groove opened at the bottom of the processing tank body 1; The conveyor belt 201 is externally equipped with a drive device and a support frame; the water turbine 301 is connected to the support frame externally equipped with the conveyor belt 201 via a connecting assembly; The bottom of the water turbine 301 is aligned with one side of the drainage chamber 304; Two conveyor belts 201 are symmetrically arranged; Both ends of the collection bin 303 are located at the bottom of both ends of the conveyor belt 201.

[0043] In this embodiment, the rotation directions of the water turbine 301 and the force plate 302 are opposite, but the conveyor belt 201 is electrically driven. Therefore, when the force plate 302 rotates, it is continuously impacted by the water flow and driven to rotate to the other side by the conveyor belt 201. This causes one end of the force plate 302 to continuously collide with the outer wall of the conveyor belt 201, causing the conveyor belt 201 to vibrate continuously at a low frequency. This causes the water turbine 301 to vibrate as soon as it starts. When it rotates to the bottom, the sediment in the opening of the water turbine 301 is discharged into the collection chamber 303 for collection. The mine water is then introduced into the treatment tank body 1. Inside, because the treatment tank body 1 has a trough and the conveyor belt 201 runs through the trough, the treatment tank body 1 is not sealed. To prevent water leakage, sealing rings 202 are installed on both sides of the outer wall of the conveyor belt 201. However, since the conveyor belt 201 is also permeable to water, sealing blocks 204 are also installed. During the process of introducing mine water, pouring in chemicals, stirring, and settling, the electrically controlled valve body 6 at the bottom of the outer wall of one side of the treatment tank body 1 is closed. When the mine water inside one side of the treatment tank body 1 is settling, the user can activate the electrically controlled two-way valve body 5 to close one side of the water inlet pipe 4 and allow the other side of the water inlet pipe 4 to open. Open the valve, then introduce the mine water into the other treatment tank body 1 and repeat the above operation. While the above operation is being performed on the other treatment tank body 1, the mine water inside the treatment tank body 1 on one side has basically settled. At this time, the user can activate the electrically controlled valve body 6 at the bottom of the outer wall of the treatment tank body 1 on one side to discharge the mine water. When introducing the mine water into the treatment tank body 1, because the treatment tank body 1 has a trough and the conveyor belt 201 passes through the trough, the treatment tank body 1 is not sealed at this time. In order to prevent water leakage, sealing rings 202 are provided on both sides of the outer wall of the conveyor belt 201, but the conveyor belt 201... Since 01 is a water-permeable state, a sealing block 204 is installed. When the conveyor belt 201 stops, that is, when there is water inside the treatment tank body 1, the sealing block 204 is squeezed by the telescopic rod 205 and the spring 206 and inserted into the opening of the conveyor belt 201. At this time, the sealing block 204 fits against the opening of the conveyor belt 201, thus forming a sealed state for the treatment tank body 1. When the conveyor belt 201 is running, the sealing block 204 is squeezed upward and moves upward. When it passes the next opening of the conveyor belt 201, it will be reinserted into the opening of the conveyor belt 201, forming an intermittent rapid sealing state.

[0044] It also includes a fine filtration and recharge mechanism 7 located at the front of the collection chamber 303; The fine filtration and recharge mechanism 7 includes a water pump 701 located at the front of the drainage chamber 304. The output end of the water pump 701 is connected to a connecting pipe 702, and one end of the connecting pipe 702 is connected to a filter chamber 703. One end of the drive device for the conveyor belt 201 is movably connected to a drive bevel gear 705.

[0045] In this embodiment, after sewage pretreatment, water is discharged into the inner wall of the drainage chamber 304. At this time, the water pump 701 will start to discharge the water inside the drainage chamber 304 into the inner wall of the filter chamber 703 through the connecting pipe 702. Because even after sewage pretreatment, there will still be small residues. When these residues pass through the reinjection pipe, the accumulation of the residues due to repeated use will cause the pipe to become blocked. Since the active bevel gear 705 is connected to the drive assembly of the conveyor belt 201, when the drive assembly of the conveyor belt 201 drives the conveyor belt 201 to rotate, it will synchronously drive the active bevel gear 705 to rotate. When the active bevel gear 705 rotates, it will drive the driven bevel gear 706 and the drive wheel 707 to rotate synchronously.

[0046] A driven bevel gear 706 is movably disposed on the top of the driving bevel gear 705, and the driving bevel gear 705 and the driven bevel gear 706 form a meshing transmission connection; The top of the driven bevel gear 706 is movably connected to the driving wheel 707, and the outer wall of the driving wheel 707 is surrounded by a belt 708, with one end of the belt 708 connected to the driven wheel 709. A rotating rod 710 is movably connected to the bottom of the driven wheel 709; The inner wall of the filter chamber 703 is provided with an annular filter screen 711, and the outer wall of the rotating rod 710 is surrounded by scrapers. A drain pipe 704 is connected to one side of the outer wall of the filter compartment 703; The bottom of the filter chamber 703 is equipped with a slag discharge chamber 712.

[0047] In this embodiment, when the drive wheel 707 rotates, it drives the driven wheel 709 to rotate via the belt 708. When the driven wheel 709 rotates, it drives the rotating rod 710 to rotate. Simultaneously, the pre-treated water is discharged into the inner wall of the filter chamber 703 and filtered by the annular filter screen 711. The filtered residue is adsorbed on the outer wall of the annular filter screen 711. When the rotating rod 710 rotates, the scraper on its outer wall can scrape off the residue. The residue is discharged into the slag discharge chamber 712 at the bottom of the filter chamber 703, and the water filtered in the second stage is reinjected through the drain pipe 704.

[0048] Working principle: When using this type of mine water pretreatment and reinjection equipment, if... Figure 1 , Figure 2 , Figure 4As shown, the electrically controlled two-way valve body 5 and the electrically controlled valve body 6 can be started and stopped by electrical control in the prior art. At the same time, the treatment tank body 1 is equipped with a stirring device inside. After starting the device, the user first starts the electrically controlled two-way valve body 5 to introduce mine water into the interior of the treatment tank body 1 from one side water inlet pipe 4. After pouring the reagent into the interior of the treatment tank body 1, the stirring device is started to stir. After stirring is completed, sedimentation can be carried out. During the process of introducing mine water, pouring reagent, stirring and sedimentation, the electrically controlled valve body 6 at the bottom of the outer wall of the treatment tank body 1 is in a closed state. When the mine water inside the treatment tank body 1 is settling, the user can start the electrically controlled two-way valve body 5 to close one side water inlet pipe 4 and open the other side water inlet pipe 4. Then, the mine water is introduced into the interior of the treatment tank body 1 on the other side and the above operation is repeated. When the above operation is carried out on the other side of the treatment tank body 1, the mine water inside the treatment tank body 1 on one side has basically settled. At this time, the user can start the electrically controlled valve body 6 at the bottom of the outer wall of the treatment tank body 1 on one side to discharge the mine water.

[0049] When the mine water inside the treatment tank 1 settles, the sediment gradually falls onto the outer wall of the conveyor belt 201. The opening on the outer wall of the conveyor belt 201 can hold the sediment in this space. When the treatment tank 1 is settling, the conveyor belt 201 is stopped. After the sedimentation in the treatment tank 1 is complete and the user activates the electrically controlled valve 6 at the bottom of the outer wall of the treatment tank 1, the conveyor belt 201 can be started by the drive device. At the same time, the direction of rotation of the conveyor belt 201 is towards the treatment tank 1 on the other side. When the conveyor belt 201 starts running, the opening of the conveyor belt 201 can transport the sediment out of the tank of the treatment tank 1. When the conveyor belt 201 rotates to the bottom, some of the sediment in the opening of the conveyor belt 201 will fall directly onto the inner wall of the collection chamber 303 due to gravity, but there may still be some residue in the opening.

[0050] Therefore, when the treatment tank body 1 on one side starts to drain water through the electrically controlled valve body 6, the water flow will pass through the conveyor belt 201 and flow onto the force plate 302 set on the outer wall of the water wheel 301. The force plate 302 will be driven to rotate by the impact of the water flow. The rotation directions of the water wheel 301 and the force plate 302 are opposite, but the conveyor belt 201 is electrically driven. So when the force plate 302 rotates, it will be continuously impacted by the water flow and driven to rotate to the other side by the conveyor belt 201. This causes one end of the force plate 302 to continuously collide with the outer wall of the conveyor belt 201, causing the conveyor belt 201 to vibrate continuously at a low frequency. This causes the water wheel 301 to vibrate when it is first started. When it rotates to the bottom, the sediment in the opening of the water wheel 301 will be discharged into the collection chamber 303 for collection.

[0051] When mine water is introduced into the treatment tank body 1, because the treatment tank body 1 has a trough and the conveyor belt 201 passes through the trough, the treatment tank body 1 is not in a sealed state at this time. In order to prevent water leakage, sealing rings 202 are provided on both sides of the outer wall of the conveyor belt 201. However, the conveyor belt 201 is also in a state where water can pass through, so a sealing block 204 is provided. When the conveyor belt 201 stops, that is, when there is water inside the treatment tank body 1, the sealing block 204 is squeezed by the telescopic rod 205 and the spring 206 and inserts into the opening of the conveyor belt 201. At this time, the sealing block 204 fits against the opening of the conveyor belt 201, thus making the treatment tank body 1 a sealed state. When the conveyor belt 201 is running, the sealing block 204 is squeezed upward and moves upward. When it passes the next opening of the conveyor belt 201, it will be reinserted into the opening of the conveyor belt 201, forming an intermittent and rapid sealing state.

[0052] After passing through the water turbine 301 and the load-bearing plate 302, the mine water will fall into the drainage chamber 304 for discharge and further processing. The sediment collected inside the collection chamber 303 can be centrally processed. At the same time, when sediment is settling on one side of the treatment tank 1, the user can directly activate the other side of the treatment tank 1 through the electrically controlled two-way valve body 5, making the overall process smoother and improving processing efficiency.

[0053] After wastewater pretreatment, water is discharged into the inner wall of the drainage chamber 304. At this time, the water pump 701 will start to discharge the water inside the drainage chamber 304 into the inner wall of the filter chamber 703 through the connecting pipe 702. Because even after pretreatment, wastewater still contains small residues, these residues can cause blockages in the reinjection pipe due to accumulation from repeated use. Since the active bevel gear 705 is connected to the drive assembly of the conveyor belt 201, when the drive assembly of the conveyor belt 201 drives the conveyor belt 201 to rotate, it will synchronously drive the active bevel gear 705 to rotate. When the active bevel gear 705 rotates, it will drive the filter chamber 703 to rotate. The moving bevel gear 706 and the driving wheel 707 rotate synchronously. When the driving wheel 707 rotates, it drives the driven wheel 709 to rotate via the belt 708. When the driven wheel 709 rotates, it drives the rotating rod 710 to rotate. Simultaneously, the pre-treated water is discharged into the inner wall of the filter chamber 703 and filtered by the annular filter screen 711. The filtered residue is adsorbed on the outer wall of the annular filter screen 711. When the rotating rod 710 rotates, the scraper on its outer wall can scrape off the residue. The residue is discharged into the slag discharge chamber 712 at the bottom of the filter chamber 703. The water filtered in the second stage is reinjected through the drain pipe 704. Thus, the work of this invention is completed.
