Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, and in particular to a wastewater treatment equipment for use in mines. Background Technology

[0002] Hydrocyclones are devices used to separate and remove heavier, coarse particles such as mud and sand from wastewater. They are sometimes also used for slurry dewatering. There are two types: pressure and gravity. They are typically constructed using a cylindrical structure or metal pipe. Water enters tangentially from the top of the structure (or metal pipe) under pressure or gravity. Under centrifugal force, coarse particles are thrown against the vessel wall and rotate downwards, being discharged along with the concentrated liquid. Smaller particles rotate to a certain extent and are discharged with a secondary upward vortex. It should be noted that hydrocyclones are core pretreatment and classification / concentration equipment for mine wastewater treatment. They rapidly achieve solid-liquid separation, particle classification, heavy metal pre-concentration, and water reuse through centrifugal force, significantly reducing the load and cost of subsequent treatment processes.

[0003] However, mine wastewater contains a large amount of solid particles and impurities, which easily accumulate and clog the underflow inlet, causing a sharp decrease in underflow flow, overflow of coarse material, and equipment vibration. Frequent shutdowns and manual cleaning are required, which seriously affects continuous production. In addition, when there are reasons such as excessively low feed pressure, excessively high feed concentration, or severe wear inside the hydrocyclone, the underflow flow will fluctuate, disrupting the balance of the cyclone field, reducing the accuracy of classification and dewatering, and the underflow being too thin or too thick will affect subsequent processes, causing a sharp drop in classification efficiency, severe overflow of coarse material, increased ineffective circulation, and a significant increase in power consumption, which seriously affects the wastewater treatment efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater treatment device for mining, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A wastewater treatment device for mining includes a wastewater separator body, with a drain pipe and a sludge discharge hood installed on the top and bottom sides of the wastewater separator body, respectively, and a wastewater inlet pipe installed on one side of the wastewater separator body, with a transfer pipe connected to the wastewater inlet pipe. It also includes a blockage-pulling and cleaning device, which is installed on the sludge discharge hood and is used to unclog and clean the sludge discharge hood. The blockage-pulling and cleaning device includes a mounting plate, which is installed on the sludge discharge hood. An impact pull plate is provided on the bottom side of the mounting plate. A piercing rod is rotatably installed on the impact pull plate. Multiple agitating plates are installed on the piercing rod.

It also includes an excessive impact interception device, which is installed on the wastewater inlet pipe and the transfer pipe. The excessive impact interception device is used to intercept the wastewater entering the wastewater inlet pipe. The excessive impact interception device includes a wastewater transfer tank, which is installed on the wastewater inlet pipe. The transfer pipe is installed on one side of the wastewater transfer tank, and a flow interception driving plate is movably installed inside the wastewater transfer tank. The flow interception driving plate moves to intercept the wastewater entering the wastewater inlet pipe.

[0006] Furthermore, in a preferred embodiment of the present invention, the blockage pull-back cleaning device further includes a follower rotating column, which is rotatably mounted on the bottom side of the impact pull plate, and the piercing rotating rod is mounted on the follower rotating column; The follower rotating column is provided with a drive thread groove, and a U-shaped positioning frame is installed on the mounting plate, with one end of the U-shaped positioning frame movably installed in the drive thread groove.

[0007] Furthermore, in a preferred embodiment of the present invention, a blocking rotating plate is rotatably mounted on the U-shaped positioning frame, the blocking rotating plate being used to hold the position of the impact pull plate; The blocking plate has a rotating groove, and a rotating retaining ring is rotatably installed in the rotating groove. The rotating retaining ring is sleeved on the U-shaped positioning frame.

[0008] Furthermore, in a preferred embodiment of the present invention, an impact groove is provided on the bottom side of the mounting sleeve, and the impact rod is movably installed in the impact groove; An impact spring is installed on the inner wall of the impact groove, and the impact spring is mounted on the impact rod.

[0009] Furthermore, in a preferred embodiment of the present invention, the excessive impact interception device further includes an interception driving plate, which is mounted on the interception baffle. A support spring is installed on the bottom side of the flow interception plate, and the support spring is installed on the wastewater transfer tank.

[0010] Furthermore, in a preferred embodiment of the present invention, an impact drive frame is sleeved on one of the impact pull rods, a transfer frame is movably mounted on the impact drive frame, and a lifting drive frame is movably mounted on the transfer frame, and the flow-stopping drive plate is movably mounted on the lifting drive frame; The lifting drive frame is provided with a horizontal slot, and a horizontal insert block is movably inserted into the horizontal slot. The horizontal insert block is installed on the wastewater transfer tank.

[0011] Furthermore, in a preferred embodiment of the present invention, a buffer movable groove is provided on the lifting drive frame, and the adapter frame is movably installed in the buffer movable groove; The impact drive frame is provided with an outer pull groove, and the adapter frame is movably installed in the outer pull groove; A retraction spring is installed on the inner wall of the outer pull groove, and the retraction spring is mounted on the adapter frame.

[0012] Furthermore, in a preferred embodiment of the present invention, a blocking and flow-cutting device is also included. The blocking and flow-cutting device is installed on the excessive impact interception device, and the blocking and flow-cutting device is used to drive the excessive impact interception device to intercept the wastewater entering the wastewater inlet pipe. The blocking and flow-stopping device includes a rotating pressure rod, which is rotatably mounted on the wastewater transfer tank, and the flow-stopping drive plate is movably mounted on the rotating pressure rod.

[0013] Furthermore, in a preferred embodiment of the present invention, a rotating pressure shaft and a supporting rotating shaft are rotatably mounted on the rotating pressure rod, and the supporting rotating shaft is mounted on the wastewater transfer tank; The flow-cutting drive plate is provided with a downward drive groove, and the rotating pressure shaft is movably installed in the downward drive groove; The lifting drive frame is equipped with a transverse push frame. The movement of the lifting drive frame drives the rotating pressure rod to rotate through the transverse push frame, which in turn drives the flow-cutting drive plate to move downward.

[0014] Furthermore, in a preferred embodiment of the present invention, a shrink-driven frame is mounted on the adapter frame, and a passive compression wheel is rotatably mounted on the shrink-driven frame; A positioning block is installed on one of the mounting sleeves. The adapter frame drives the shrink driven frame to move upward, causing the passive compression wheel to be squeezed by the positioning block, which is used to drive the adapter frame to move laterally.

[0015] The beneficial effects of the wastewater treatment equipment for mining proposed in this invention are: In this invention, by setting up a blockage-pull-back cleaning device, when the wastewater separator body is treating mine wastewater, if blockage or siltation occurs inside the wastewater separator body, reducing the flow rate of silt discharged from the silt discharge hood, then two impact pull rods pull the impact pull plate upwards. The upward movement of the impact pull plate drives the piercing rod upwards, piercing the outlet of the silt discharge hood, and simultaneously drives the follower rotating column upwards. The upward movement of the follower rotating column drives the threaded groove to move on the U-shaped positioning frame, thereby causing the follower rotating column to rotate. The rotation of the follower rotating column drives the piercing rod to rotate, and the piercing rod drives multiple agitator plates to rotate, achieving the purpose of automatic and real-time unblocking of the silt discharge hood, thereby ensuring the treatment efficiency of the wastewater separator body.

[0016] Furthermore, in this invention, by setting up an excessive impact interception device, when the impact force of the sludge discharged from the sludge discharge hood is too large, the impact pull plate moves downward. The downward movement of the impact pull plate drives the impact drive frame to move downward through an impact pull rod. The downward movement of the impact drive frame drives the lifting drive frame to move downward through a transfer frame. The lifting drive frame drives the interception baffle to move downward through the interception drive plate, thereby intercepting the wastewater in the wastewater transfer tank, achieving adaptive flow balance, stabilizing the flow field and pressure inside the hydrocyclone, ensuring classification accuracy and stable underflow concentration, solving the problem of flow fluctuation, and ensuring the treatment effect of the wastewater separator.

[0017] Furthermore, in this invention, by setting up a blockage and flow interruption device, if the sludge discharge hood is continuously blocked and unblocking is ineffective, the flow interruption plate will move the flow interruption baffle downward to close the wastewater transfer tank, thus avoiding the problem of continuous feeding when the sludge discharge hood is blocked, thereby preventing a large amount of untreated wastewater from flowing out directly.

[0026] Please refer to the attached instruction manual. Figures 1-11 The present invention provides a wastewater treatment device for mining, which includes a wastewater separator body 1, a drain pipe 4 and a mud and sand discharge cover 3 respectively installed on the top and bottom sides of the wastewater separator body 1, and a wastewater inlet pipe 2 installed on one side of the wastewater separator body 1, with a transfer pipe 5 connected to the wastewater inlet pipe 2.

[0027] Further, please refer to the appendix to the instruction manual. Figures 2-5 The wastewater treatment equipment for mining provided in this embodiment of the invention also includes a blockage pull-back cleaning device 6, which is installed on the mud and sand discharge hood 3 and is used to unclog and clean the mud and sand discharge hood 3. Specifically, the blockage pull-back cleaning device 6 includes a mounting plate 601, which is mounted on the mud and sand discharge cover 3. An impact pull plate 602 is provided on the bottom side of the mounting plate 601. A piercing rod 607 is rotatably mounted on the impact pull plate 602. Multiple agitating plates 608 are mounted on the piercing rod 607. Two mounting sleeves 603 are installed on the bottom side of the mounting plate 601. An impact pull rod 604 is movably mounted inside the mounting sleeve 603. The impact pull plate 602 is mounted on the impact pull rod 604.

[0028] It should be noted that, in this embodiment of the invention, when blockage or siltation occurs inside the wastewater separator body 1, reducing the flow rate of silt discharged from the silt discharge hood 3 and thus lacking sufficient impact force to keep the impact pull plate 602 in position, the contraction force of the two impact springs 606 causes the two impact pull rods 604 to pull the impact pull plate 602 upward. The upward movement of the impact pull plate 602 drives the opening rod 607 upward, opening the outlet of the silt discharge hood 3. At the same time, it drives the follower rotating column 609 upward. The upward movement of the follower rotating column 609 drives the threaded groove 611 to move upward on the U-shaped positioning frame 610, thereby causing the follower rotating column 609 to rotate. The rotation of the follower rotating column 609 drives the opening rod 607 to rotate, which in turn drives multiple agitating rotating plates 608 to rotate, clearing the silt discharge hood 3 and thus ensuring the processing efficiency of the wastewater separator body 1.

[0029] More specifically, in this embodiment of the invention, an excessive impact interception device 7 is also included. The excessive impact interception device 7 is installed on the wastewater inlet pipe 2 and the transfer pipe 5. The excessive impact interception device 7 is used to intercept the wastewater entering the wastewater inlet pipe 2. The excessive impact interception device 7 includes a wastewater transfer tank 701, which is installed on the wastewater inlet pipe 2. The transfer pipe 5 is installed on one side of the wastewater transfer tank 701. A flow interception driving plate 703 is movably installed inside the wastewater transfer tank 701. The flow interception driving plate 703 moves to intercept the wastewater entering the wastewater inlet pipe 2. It should be noted that in this embodiment of the invention, if the impact force of the mud and sand discharged from the mud and sand discharge hood 3 is too large, causing the impact pull plate 602 to move excessively downward, the lifting drive frame 705 will drive the interception baffle 702 to move downward through the interception drive plate 703, thereby intercepting the wastewater in the wastewater transfer tank 701, achieving the purpose of reducing the wastewater inflow or directly sealing it, thus effectively avoiding a series of problems caused by excessive flow.

[0030] Please continue to refer to the instruction manual appendix. Figures 2-5Furthermore, the wastewater treatment equipment for mining provided in this embodiment of the invention includes a blockage-removing and cleaning device 6 that further comprises a follower rotating column 609. The follower rotating column 609 is rotatably mounted on the bottom side of the impact pull plate 602, and a piercing rotating rod 607 is mounted on the follower rotating column 609. A drive threaded groove 611 is provided on the follower rotating column 609, and a U-shaped positioning frame 610 is mounted on the mounting plate 601. One end of the U-shaped positioning frame 610 is movably mounted in the drive threaded groove 611. It should be noted that in this embodiment of the invention, when the follower rotating column 609 moves upward, it moves upward on the U-shaped positioning frame 610 through the drive threaded groove 611, thereby causing the follower rotating column 609 to rotate. The rotation of the follower rotating column 609 drives the piercing rotating rod 607 to rotate, which in turn drives multiple agitating rotating plates 608 to rotate, thereby clearing the mud and sand discharge hood 3.

[0031] More specifically, in this embodiment of the invention, a blocking rotating plate 612 is rotatably mounted on the U-shaped positioning frame 610. The blocking rotating plate 612 is used to hold the position of the impact pull plate 602. A rotating stop groove 613 is formed on the blocking rotating plate 612, and a rotating stop ring 614 is rotatably mounted in the rotating stop groove 613. The rotating stop ring 614 is sleeved on the U-shaped positioning frame 610. It should be noted that in this embodiment of the invention, the U-shaped positioning frame 610 rotates through the rotating stop groove 613 and the rotating stop ring 614, thus restricting the U-shaped positioning frame 610 to only be able to rotate.

[0032] Please refer to the instruction manual attached. Figures 1-11 More specifically, in this embodiment of the invention, an impact groove 605 is provided on the bottom side of the mounting sleeve 603, and an impact rod 604 is movably installed in the impact groove 605; an impact spring 606 is installed on the inner wall of the impact groove 605, and the impact spring 606 is installed on the impact rod 604. It should be noted that, in this embodiment of the invention, by providing the impact spring 606, the impact plate 602 can be pulled back by the impact rod 604 when the impact force is insufficient.

[0033] Please refer to the instruction manual attached. Figure 2 and Figures 6-11 Furthermore, the wastewater treatment equipment for mining provided in this embodiment of the invention includes an over-impact interception device 7, which further comprises an interception driving plate 703 mounted on an interception baffle 702. A support spring 704 is mounted on the bottom side of the interception driving plate 703 and is mounted on the wastewater transfer tank 701. It should be noted that, in this embodiment of the invention, the support spring 704 is used to support the position of the interception driving plate 703.

[0034] More specifically, in this embodiment of the invention, an impact drive frame 706 is sleeved on an impact pull rod 604, a transition frame 707 is movably mounted on the impact drive frame 706, and a lifting drive frame 705 is movably mounted on the transition frame 707. A flow-stopping drive plate 703 is movably mounted on the lifting drive frame 705. A horizontal slot 711 is provided on the lifting drive frame 705, and a horizontal insertion block 712 is movably inserted into the horizontal slot 711. The horizontal insertion block 712 is mounted on the wastewater transfer tank 701. It should be noted that in this embodiment of the invention, when the transition frame 707 moves and drives the lifting drive frame 705 to move laterally, the lifting drive frame 705 disengages from the horizontal insertion block 712, thereby achieving the purpose of automatically disconnecting the lifting drive frame 705 from the wastewater transfer tank 701.

[0035] More specifically, in this embodiment of the invention, a buffer movable groove 708 is provided on the lifting drive frame 705, and the adapter frame 707 is movably installed in the buffer movable groove 708; Furthermore, the impact drive frame 706 is provided with an outer pull groove 709, and the adapter frame 707 is movably installed in the outer pull groove 709; a retraction spring 710 is installed on the inner wall of the outer pull groove 709, and the retraction spring 710 is installed on the adapter frame 707. It should be noted that, in this embodiment of the invention, when the impact pull plate 602 moves or the adapter frame 707 moves upward, the adapter frame 707 moves in the buffer movable groove 708, and will not drive the lifting drive frame 705 to move vertically. When the passive compression wheel 805 is squeezed by the positioning block 806, the passive compression wheel 805 drives the adapter frame 707 to pull outward through the contraction of the driven frame 804, so that the adapter frame 707 moves in the outer pull groove 709, and the retraction spring 710 is stretched by force. Therefore, the retraction force of the retraction spring 710 can drive the adapter frame 707 to return to its original position.

[0036] Please refer to the instruction manual attached. Figure 2 and Figures 7-8 Furthermore, in this embodiment of the invention, a blocking and flow interruption device 8 is also included. The blocking and flow interruption device 8 is installed on the excessive impact interception device 7. The blocking and flow interruption device 8 is used to drive the excessive impact interception device 7 to intercept the wastewater entering the wastewater inlet pipe 2. Specifically, the blockage and flow interruption device 8 includes a rotating pressure rod 801, which is rotatably mounted on the wastewater transfer tank 701, and a flow-blocking drive plate 703 is movably mounted on the rotating pressure rod 801. It should be noted that, in this embodiment of the invention, when the sludge discharge hood 3 is continuously blocked and unblocking is ineffective, the rotating pressure rod 801 drives the flow-blocking drive plate 703 to move, thereby causing the flow-blocking drive plate 703 to drive the flow-blocking baffle 702 to move downwards and close the wastewater transfer tank 701, thus preventing continuous feeding even when the sludge discharge hood 3 is blocked.

[0037] More specifically, in this embodiment of the invention, a rotating pressure shaft 802 and a supporting rotating shaft 808 are rotatably mounted on the rotating pressure rod 801, and the supporting rotating shaft 808 is mounted on the wastewater transfer box 701; a downward moving groove 803 is opened on the intercepting driving plate 703, and the rotating pressure shaft 802 is movably mounted in the downward moving groove 803; Furthermore, a transverse pushing frame 807 is installed on the lifting drive frame 705. The movement of the lifting drive frame 705 drives the rotating pressure rod 801 to rotate via the transverse pushing frame 807, which in turn drives the flow-stopping drive plate 703 to move downward. It should be noted that, in this embodiment of the invention, when the lifting drive frame 705 moves laterally, it drives the transverse pushing frame 807 to move. The transverse pushing frame 807 drives the rotating pressure rod 801 to rotate. The rotating pressure rod 801 rotates on the supporting rotating shaft 808. At the same time, the rotation of the rotating pressure rod 801 drives the flow-stopping drive plate 703 to move via the rotating pressure shaft 802, and causes the rotating pressure shaft 802 to slide within the downward driving groove 803. This causes the flow-stopping drive plate 703 to drive the flow-stopping baffle 702 to move downward, closing the wastewater transfer tank 701 and achieving the purpose of automatic closure of the wastewater transfer tank 701.

[0038] More specifically, in this embodiment of the invention, a retractable driven frame 804 is mounted on the adapter frame 707, and a passive compression wheel 805 is rotatably mounted on the retractable driven frame 804. Furthermore, a positioning block 806 is mounted on a mounting sleeve 603. The adapter frame 707 drives the retractable driven frame 804 upward, causing the passive compression wheel 805 to be compressed by the positioning block 806, thereby driving the adapter frame 707 to move laterally. It should be noted that in this embodiment of the invention, when the impact pull plate 602 continuously moves upward, the impact pull rod 604 moves, driving the retractable driven frame 804 to move via the adapter frame 707, causing the passive compression wheel 805 to be compressed by the positioning block 806. This, in turn, causes the passive compression wheel 805 to pull the adapter frame 707 outward via the retractable driven frame 804, thereby achieving the purpose of disengaging the lifting drive frame 705 from the horizontal insert block 712.

[0039] In summary, the working principle of the wastewater treatment equipment for mining provided in this embodiment of the invention is as follows: When the wastewater in the wastewater separator body 1 is treating the wastewater from the mine, the wastewater enters the wastewater transfer tank 701 through the transfer pipe 5, then enters the wastewater inlet pipe 2 through the wastewater transfer tank 701, and then enters the wastewater separator body 1 through the wastewater inlet pipe 2. Subsequently, the sludge is discharged through the sludge discharge hood 3. The treated water is discharged through the drain pipe 4. Then, the blocking plate 612 is rotated, so that the blocking plate 612 rotates on the rotating retaining ring 614 through the rotating retaining groove 613, thereby unlocking the impact pull plate 602. It should be noted that during the wastewater treatment process, if blockage or siltation occurs inside the wastewater separator body 1, the flow rate of silt discharged from the silt discharge hood 3 will decrease, resulting in insufficient impact force to keep the impact pull plate 602 in position. At this time, under the contraction force of the two impact springs 606, the two impact pull rods 604 pull the impact pull plate 602 upward. The upward movement of the impact pull plate 602 drives the opening rod 607 upward, opening the outlet of the silt discharge hood 3, and simultaneously driving the follower rotating column 609 upward. The upward movement of the follower rotating column 609 drives the threaded groove 611 to move upward on the U-shaped positioning frame 610, thereby causing the follower rotating column 609 to rotate. The rotation of the follower rotating column 609 drives the opening rod 607 to rotate, which in turn drives multiple agitating rotating plates 608 to rotate, clearing the silt discharge hood 3 and thus ensuring the treatment efficiency of the wastewater separator body 1. It should be further explained that if the impact force of the sludge discharged from the sludge discharge hood 3 is too large, causing the impact pull plate 602 to move downward, the impact pull plate 602 moves downward within the two impact pull grooves 605 through the two impact pull rods 604, and causes the two impact springs 606 to be stretched. The downward movement of the impact pull plate 602 drives the impact drive frame 706 to move downward through one impact pull rod 604. The downward movement of the impact drive frame 706 drives the lifting drive frame 705 to move downward through the adapter frame 707. This causes the lifting drive frame 705 to drive the intercepting baffle 702 to move downward through the intercepting drive plate 703, thereby intercepting the wastewater in the wastewater transfer tank 701, thus effectively avoiding a series of problems caused by excessive flow. Furthermore, if the sludge discharge hood 3 continues to be blocked and unblocking is ineffective, causing the flow rate of the sludge discharge hood 3 to decrease, then under the contraction force of the two impact springs 606, the two impact pull rods 604 will pull the impact pull plate 602 to move continuously upward. The movement of the impact pull rods 604 will drive the retraction driven frame 804 to move through the adapter frame 707, causing the passive extrusion wheel 805 to be squeezed by the positioning block 806. In turn, the passive extrusion wheel 805 will drive the adapter frame 707 to be pulled outward through the retraction driven frame 804. The adapter frame 707 will move in the outward pull groove 709, and the retraction spring 710 will be stretched by force. It should be noted that the movement of the adapter frame 707 causes the lifting drive frame 705 to move, causing the lifting drive frame 705 to disengage from the horizontal insertion block 712, thereby causing the lifting drive frame 705 to lose connection with the wastewater transfer box 701. At the same time, the horizontal movement of the lifting drive frame 705 causes the horizontal movement push frame 807 to move, causing the horizontal movement push frame 807 to push the rotating pressure rod 801 to rotate. The rotating pressure rod 801 rotates on the support rotating shaft 808. The rotation of the rotating pressure rod 801 drives the flow intercepting drive plate 703 to move through the rotating pressure shaft 802, and causes the rotating pressure shaft 802 to slide in the downward drive groove 803. This causes the flow intercepting drive plate 703 to drive the flow intercepting baffle 702 to move downward and close the wastewater transfer box 701, preventing the problem of continuous feeding when the mud and sand discharge hood 3 is blocked.
