Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a mining wastewater treatment device. Background Technology

[0002] Mining wastewater typically contains large amounts of suspended solids, heavy metal ions (such as copper, lead, zinc, mercury, cadmium, etc.), acidic and alkaline substances, and other harmful chemicals. If discharged directly without treatment, it will cause serious environmental pollution. Therefore, mining wastewater needs to be treated before discharge. Existing wastewater treatment ponds, such as the one disclosed in authorization announcement number CN210193580U, include a pond body. The interior of the pond body is divided into a clean pond, a purification pond, a sterilization pond, and a filtration pond by partitions. The clean pond, purification pond, sterilization pond, and filtration pond are connected by a communication port on the partitions. A buffer device is fixed at the bottom of the pond body to help buffer the load on the wastewater pond. An ultraviolet germicidal lamp is fixed to the inner top side surface of the sterilization pond with bolts to increase the stability of the ultraviolet germicidal lamp and to sterilize the wastewater in the sterilization pond by using the ultraviolet germicidal lamp, thereby reducing the growth of bacteria.

[0003] Mining wastewater is typically treated by settling it in a sedimentation tank, then filtering it through a filtration tank with screens and grates to remove impurities, before finally discharging it into a neutralization tank for pH adjustment. Existing wastewater treatment tanks are similar to the aforementioned technologies. However, during pH adjustment, the amount of chemicals added varies each time the mining wastewater is discharged, as it may be acidic or alkaline. After neutralization, the pH can be tested by sampling the wastewater. However, due to the large tank size, similar to existing technologies, sampling from different locations is inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mining wastewater treatment device that, after acid-base adjustment, facilitates sampling and testing of wastewater from different locations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mining wastewater treatment device, comprising a sedimentation tank, a filtration tank, and a neutralization tank. Fixed cylinders are rotatably installed at both ends of the neutralization tank. A connecting cylinder is fixedly arranged between two of the fixed cylinders. Multiple V-shaped shells are fixedly installed between the two fixed cylinders. Sealing components are provided at both ends of each V-shaped shell. Multiple sampling ports are opened on the outer side of each V-shaped shell. A connecting member for sealing the sampling ports is provided inside each V-shaped shell. A rotating component for controlling the movement of the connecting member is rotatably installed inside the connecting cylinder. A stirring blade is fixedly installed on the outer side of the V-shaped shell. A power component for controlling the rotation of the fixed cylinders is fixedly installed on the outer side of the neutralization tank.

[0006] Preferably, the connector includes a V-shaped plate located inside the V-shaped housing, a narrow plate is slidably disposed inside the sampling port, and a sealing plate for sealing the sampling port is fixedly installed at the outer end of the narrow plate, and the narrow plate is fixedly connected to the V-shaped plate.

[0007] Preferably, a sealing frame is fixedly sleeved on the outer side of the sealing plate.

[0008] Preferably, the rotating component includes a rotating rod rotatably connected to the connecting cylinder, two connecting gears are fixedly sleeved on the rotating rod, and multiple serrated plates are meshed around the connecting gears. The multiple serrated plates are staggered, and the outer ends of the serrated plates pass through the connecting cylinder and connect to the V-shaped plate. A limit member is provided between the rotating rod and the connecting cylinder.

[0009] Preferably, the limiting component includes a ring fixedly installed inside the connecting cylinder, with multiple limiting grooves opened on the inner side of the ring, a collar sleeved on the outer side of the rotating rod, and multiple arc-shaped spring pieces corresponding to the positions of the limiting grooves fixedly installed at equal intervals on the outer side of the collar.

[0010] Preferably, one end of the rotating rod is fixedly connected to an indicator arrow through the connecting cylinder.

[0011] Preferably, the power assembly includes a bracket fixedly installed on the outer wall of the neutralization tank, a motor fixedly installed on the bracket, a rotating gear fixedly installed at the output end of the motor, and a toothed ring meshing with the rotating gear is sleeved on the outer side of one of the fixed cylinders.

[0012] Preferably, the fixed cylinder extends through both ends of the V-shaped housing, and the sealing assembly includes a sealing plug disposed at the end of the V-shaped housing. A fixing plate is fixedly installed on the outside of the sealing plug, and a spring is disposed between the fixing plate and the fixed cylinder.

[0013] Preferably, one end of the connecting cylinder is rotatably connected to a connecting pipe, the connecting pipe is connected to an external water supply device, and the connecting cylinder is fixedly connected to multiple V-shaped shells by conduits.

[0014] Preferably, both the sedimentation tank and the filtration tank are equipped with a cover plate at the top, and a water pump is installed on the cover plate. Water is transferred between the sedimentation tank, the filtration tank and the neutralization tank through the water pump.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention fixes multiple V-shaped shells between two fixed cylinders and opens multiple sampling ports on the outside of the V-shaped shells. When sampling is required, the sampling ports can be opened to collect wastewater from different locations in the neutralization tank. Then the sampling ports are closed, and the ends of the V-shaped shells are opened to take out the wastewater for pH value testing, avoiding the need to extract samples only from the edge of the neutralization tank.

[0016] 2. This invention, by fixing stirring blades on the outside of the V-shaped shell and starting the motor, not only controls the movement of the V-shaped shell to collect wastewater from different locations, but also facilitates the discharge of wastewater by starting the motor after collection. Before the neutralization reaction, after adding the reagent, starting the motor can also stir the wastewater in the neutralization tank through the stirring blades, so that the reagent and wastewater are mixed more quickly, and the wastewater in the entire neutralization tank is neutralized more evenly, avoiding the wastewater in the middle of the neutralization tank not coming into contact with the reagent.

[0017] 3. The present invention rotates the connecting pipe at one end of the connecting cylinder and fixes the connecting pipe between the connecting cylinder and multiple V-shaped shells. After a sampling inspection is completed, some clean water can be introduced from the outside to clean the inside of the V-shaped shells, so as to avoid too much residue in the V-shaped shells, which would affect the results of the next sampling inspection.

Detailed Implementation

[0020] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0021] Please see Figures 1-9 A mining wastewater treatment device includes a sedimentation tank 24, a filtration tank 23, and a neutralization tank 1. Both the sedimentation tank 24 and the filtration tank 23 are equipped with covers 28 at their upper ends, and water pumps 27 are installed on the covers 28. Water is transferred between the sedimentation tank 24, the filtration tank 23, and the neutralization tank 1 via the water pumps 27. The neutralization tank 1 is also equipped with a cover 28 identical to that of the sedimentation tank 24 and the filtration tank 23. Figure 1 For demonstration purposes, the cover plate 28 can be used to install a water pump 27 to transfer the regulated water in the neutralization tank 1; A neutralization tank 1 has fixed cylinders 5 rotatably mounted at both ends. A connecting cylinder 6 is fixedly installed between the two fixed cylinders 5. Multiple V-shaped shells 7 are fixedly installed between the two fixed cylinders 5. Each end of the V-shaped shell 7 is provided with a sealing assembly, and both ends of the V-shaped shell 7 penetrate the fixed cylinders 5. The sealing assembly includes a sealing plug 30 located at the end of the V-shaped shell 7. A fixing plate 14 is fixedly installed on the outside of the sealing plug 30. A spring 20 is provided between the fixing plate 14 and the fixed cylinder 5. Multiple sampling ports are opened on the outside of the V-shaped shell 7. A connecting member is provided inside the V-shaped shell 7 to seal the sampling ports. The connecting member includes a V-shaped plate 13 located inside the V-shaped shell 7. A narrow plate 26 is slidably installed inside the sampling port. A sealing plate 11 is fixedly installed at the outer end of the narrow plate 26 to seal the sampling port. The narrow plate 26 is fixedly connected to the V-shaped plate 13. A rotating component that controls the movement of the connecting component is rotatably installed inside the connecting cylinder 6. When sampling is required, the V-shaped plate 13 can be moved by the rotating component to open multiple sampling ports. Wastewater in the neutralization tank 1 enters the V-shaped shell 7 through the sampling port. Then, the V-shaped plate 13 is reset to seal the sampling port. Then, the sealing plug 30 at the end of the V-shaped shell 7 is opened to take out the wastewater for pH value testing, avoiding the need to extract samples only from the edge of the neutralization tank 1. A stirring blade 8 is fixedly installed on the outside of the V-shaped shell 7, and a power assembly for controlling the rotation of the fixed cylinder 5 is fixedly installed on the outside of the neutralization tank 1. The power assembly includes a bracket 29 fixedly installed on the outer wall of the neutralization tank 1, a motor 2 fixedly installed on the bracket 29, and a rotating gear 3 fixedly installed at the output end of the motor 2. A toothed ring 4 that meshes with the rotating gear 3 is sleeved on the outside of one of the fixed cylinders 5. Starting the motor 2 can not only control the movement of the V-shaped shell 7 to collect wastewater at different locations, but also facilitate the discharge of wastewater by operating the motor 2 after collection (making it easy to remove the wastewater inside the V-shaped shell 7 when it is directly above). Before the neutralization reaction, after adding the reagent, starting the motor 2 can also stir the wastewater in the neutralization tank 1 through the stirring blade 8, so that the reagent and wastewater are mixed more quickly, and the wastewater in the entire neutralization tank 1 is neutralized more evenly, avoiding the wastewater in the middle of the neutralization tank 1 not coming into contact with the reagent.

[0022] As a further technical solution of the present invention, a sealing frame 25 is fixedly sleeved on the outer side of the sealing plate 11. The sealing frame 25 seals the soft plate. The sealing frame 25 is tightly attached to the outer wall of the V-shaped housing 7, resulting in a better sealing effect.

[0023] As a further technical solution of the present invention, the rotating component includes a rotating rod 17 rotatably connected to the connecting cylinder 6. Two connecting gears 12 are fixedly sleeved on the rotating rod 17. Multiple serrated plates 16 are meshed around the connecting gears 12. The multiple serrated plates 16 are staggered. The outer ends of the serrated plates 16 pass through the connecting cylinder 6 and are connected to the V-shaped plate 13. A limiting component is provided between the rotating rod 17 and the connecting cylinder 6. By controlling the rotation of the rotating rod 17 to drive the connecting gears 12 to rotate, the multiple serrated plates 16 move simultaneously. The multiple serrated plates 16 simultaneously push the multiple V-shaped plates 13 to move, thereby controlling the closed state of the sampling port.

[0024] As a further technical solution of the present invention, the limiting component includes a ring 18 fixedly installed inside the connecting cylinder 6. The inner side of the ring 18 is provided with a plurality of limiting grooves 22. A collar 19 is sleeved on the outer side of the rotating rod 17. A plurality of arc-shaped spring pieces 21 corresponding to the positions of the limiting grooves 22 are fixedly installed at equal intervals on the outer side of the collar 19. When the rotating rod 17 is controlled to rotate, it will drive the collar 19 to rotate. When the collar 19 rotates, the arc-shaped spring pieces 21 will be squeezed and deformed. When the rotating rod 17 is not rotated, the arc-shaped spring pieces 21 will be limited by the limiting grooves 22, so that the connecting gear 12 will not rotate without external force.

[0025] As a further technical solution of the present invention, one end of the rotating rod 17 is fixedly connected to the connecting cylinder 6 with an indicator arrow 15, so that when the rotating rod 17 is controlled to rotate, the position of the sealing plate 11 can be determined according to the indicator arrow 15.

[0026] As a further technical solution of the present invention, one end of the connecting cylinder 6 is rotatably connected to the connecting pipe 10, which is connected to the external water supply equipment. The connecting cylinder 6 and multiple V-shaped shells 7 are all fixedly connected to the conduit 9. After a sampling inspection is completed, some clean water can be introduced through the external water supply equipment to clean the inside of the V-shaped shell 7, so as to avoid too much residue in the V-shaped shell 7, which would affect the results of the next sampling inspection.

[0027] When the neutralization pool 1 is large, multiple sets of fixed cylinders 5 can be installed. All sets of fixed cylinders 5 have the same structure as described above and are equipped with V-shaped housings 7 for sampling. Each set of fixed cylinders 5 can be controlled by a motor 2, or they can be synchronously controlled by a chain and sprocket or a belt and pulley.

[0028] Working principle: Wastewater is allowed to settle in sedimentation tank 24, then pumped into filtration tank 23 by water pump 27 for filtration, and then pumped into neutralization tank 1 by water pump 27. At this time, the indicator arrow 15 can be rotated to drive the rotating rod 17 to rotate. The rotating rod 17 drives the two connecting gears 12 to rotate. The connecting gears 12 drive the sawtooth plate 16 that meshes with it to move. The sawtooth plate 16 pushes the V-shaped plate 13 to move. The V-shaped plate 13 pushes the narrow plate 26 to move. The width of the narrow plate 26 is smaller than the width of the sampling port. The narrow plate 26 pushes the sealing plate 11 and the sealing frame 25 to separate from the V-shaped shell 7. At this time, the water in the neutralization tank 1 enters the V-shaped shell 7 through multiple sampling ports. Then, the reverse indicator arrow 15 drives the rotating rod 17 to reverse, the rotating rod 17 drives the two connecting gears 12 to reverse, the connecting gears 12 drive the sawtooth plate 16 meshing with it to move and reset, the sawtooth plate 16 pulls the narrow plate 26 to reset through the V-shaped plate 13, and the narrow plate 26 pulls the sealing plate 11 and the sealing frame 25 to seal the sampling port. During the rotation of the rotating rod 17, the collar 19 is driven to rotate, and the collar 19 drives the arc-shaped spring 21 to move. When the arc-shaped spring 21 moves, it will be squeezed and deformed. When the rotating rod 17 is not rotated, the arc-shaped spring 21 will be limited by the limiting groove 22, so that the connecting gear 12 will not rotate without external force. Then, start motor 2 to drive rotating gear 3 to rotate, rotating gear 3 to drive gear ring 4 to rotate, gear ring 4 to drive fixed cylinder 5 connected to it to rotate, fixed cylinder 5 to drive connecting cylinder 6 and V-shaped housing 7 to rotate. When one of the V-shaped housings 7 is directly above, motor 2 stops working. At this time, pull the fixed plates 14 at both ends of the V-shaped housing 7 directly above, spring 20 is stretched, sealing plug 30 is disengaged from V-shaped housing 7, and wastewater can be taken out for pH value testing. The water in V-shaped housing 7 can be taken out and tested in sequence according to the above steps. (After the test, connect connecting pipe 10 to external water supply equipment, and then open multiple sealing plugs 30. Since the fixed plate 14 and fixed cylinder 5 are connected by spring 20, the sealing plug 30 can be misaligned with the end of V-shaped housing 7. Then, some clean water is introduced through external water supply equipment. The clean water is used to clean the inside of V-shaped housing 7 through conduit 9 to avoid too much residue in V-shaped housing 7, which would affect the results of the next sampling test.) Afterwards, reagents are added to neutralization tank 1 according to the test results. After adding the reagents, motor 2 can be started to control the movement of V-shaped shell 7 according to the above steps. V-shaped shell 7 drives stirring blade 8 to stir the wastewater in neutralization tank 1, so that the reagents and wastewater are mixed more quickly. At the same time, the wastewater in the entire neutralization tank 1 is neutralized more evenly, avoiding the wastewater in the middle of the neutralization tank 1 from not coming into contact with the reagents. After the neutralization reaction is complete, take samples of the wastewater according to the above steps to check if the pH value of the wastewater is qualified. Then, clean the V-shaped shell 7 according to the above steps.
