Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a device for treating mine wastewater contaminated with heavy metals. Background Technology

[0002] Mine wastewater containing heavy metal ions poses a serious threat to the ecological environment and human health. To treat this wastewater, wastewater treatment equipment is needed.

[0003] Existing preliminary treatment devices typically consist of a treatment tank, inlet, outlet, solenoid valve, filter screen, motor, and stirring rod. The solenoid valves are installed inside the inlet and outlet to control the flow of liquid, while the motor controls the stirring rod. The working principle is as follows: First, the solenoid valve inside the inlet is opened, allowing wastewater and wastewater treatment additives to be poured into the treatment tank. Under gravity, the wastewater and additives first come into contact with the filter screen, isolating particulate impurities. The liquid then undergoes preliminary filtration through the filter screen. Next, the motor controls the stirring rod to rotate, mixing the wastewater and additives to neutralize the wastewater. Finally, the solenoid valve inside the outlet is opened, allowing the pre-treated wastewater to flow out for subsequent treatment.

[0004] However, existing liquids fall through the outlet using only gravity, resulting in a slow flow rate that affects overall processing time and reduces work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model proposes a treatment device for mine wastewater contaminated with heavy metals.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a treatment device for mine wastewater contaminated with heavy metals, comprising a treatment tank, a filter plate inside the treatment tank, an inlet and an outlet installed at the top and bottom of the treatment tank respectively, and a solenoid valve installed inside both the inlet and outlet, a motor installed at the bottom of the treatment tank, a stirring rod fixedly connected to the output end of the motor, a compression mechanism inside the treatment tank, the compression mechanism comprising a cylinder installed at the top of the treatment tank, a motor installed at the output end of the cylinder, both the cylinder and the motor being wirelessly connected to an external controller, an isolation plate fixedly connected to the output end of the motor, the isolation plate being rotatably connected to the inside of the filter plate, and multiple sets of through holes being formed inside both the filter plate and the isolation plate.

[0007] Furthermore, a pair of limiting rods are slidably connected inside the filter plate, and both ends of the pair of limiting rods are fixedly connected to the inner wall of the processing tank.

[0008] Furthermore, a diversion ring is rotatably connected to the top of the inner wall of the treatment tank, a diversion groove is provided at the bottom of the diversion ring, a ring plate is rotatably connected inside the diversion ring, the liquid inlet passes through the ring plate, a spur gear one is fixedly connected to the outside of the liquid inlet, a spur gear two is fixedly connected to the outside of the diversion ring, the spur gear one and the spur gear two mesh with each other, and a power mechanism for driving the liquid inlet to rotate is provided around the motor.

[0009] Furthermore, the power mechanism includes a transmission rod, a first chain, and a second chain. The transmission rod is disposed around the periphery of the processing tank. The first chain engages with the output end of the motor and the outer side of the transmission rod. The second chain engages with the outer side of the transmission rod and the liquid inlet.

[0010] Furthermore, a pair of limiting rings are rotatably connected to the outer side of the transmission rod, and the ends of the pair of limiting rings away from the transmission rod are fixedly connected to the outer side of the processing barrel.

[0011] The technical effects and advantages of this utility model of a treatment device for mine wastewater contaminated with heavy metals:

[0012] (1) This utility model achieves through hole misalignment sealing by rotating the isolation plate driven by the motor, and pushes the filter plate down to compress the air chamber in conjunction with the cylinder to form a dynamic air pressure boosting effect. When the solenoid valve at the liquid outlet is opened, this mechanical coordinated action uses the air pressure difference to accelerate the directional flow of liquid, breaks through the bottleneck of traditional gravity drainage speed, and significantly shortens the wastewater treatment cycle.

[0013] (2) This utility model drives the stirring rod by motor and simultaneously rotates the first spur gear, the second spur gear and the flow divider ring synchronously. The flow divider groove is used to achieve dynamic dispersion of wastewater landing point with the circumferential displacement of the flow divider ring. Through the synergistic effect of the mechanical transmission chain, the wastewater and additives impact the filter plate surface in a periodic displacement manner, and the local load is evenly distributed to avoid the risk of filter plate deformation caused by single-point stress concentration.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 4 As shown, a treatment device for mine wastewater contaminated with heavy metals includes a treatment tank 1. A filter plate 2 is installed inside the treatment tank 1. An inlet 3 and an outlet 4 are respectively installed at the top and bottom of the treatment tank 1, and both the inlet 3 and outlet 4 are equipped with solenoid valves. A motor 5 is installed at the bottom of the treatment tank 1, and a stirring rod 6 is fixedly connected to the output end of the motor 5. A compression mechanism is installed inside the treatment tank 1, and the compression mechanism includes a cylinder 7. The cylinder 7 is installed at the top of the treatment tank 1, and a motor 8 is installed at the output end of the cylinder 7. Both the cylinder 7 and the motor 8 are wirelessly connected to an external controller. An isolation plate 9 is fixedly connected to the output end of the motor 8. The isolation plate 9 is rotatably connected inside the filter plate 2. Multiple sets of through holes are formed inside both the filter plate 2 and the isolation plate 9.

[0024] First, the solenoid valve inside the inlet 3 is opened, and wastewater and wastewater treatment additives are poured into the treatment tank 1 through the inlet 3. At this time, the wastewater and additives will first contact the filter plate 2 under the action of gravity, and particulate impurities will be isolated. The liquid will then undergo preliminary filtration through the filter plate 2. Then, the motor 5 controls the stirring rod to rotate, mixing the wastewater and additives to achieve the neutralization of wastewater by the additives. Finally, the solenoid valve inside the outlet 4 is opened, and the pre-treated wastewater falls through the outlet 4 for subsequent treatment. However, in existing systems, when the liquid falls through the outlet 4, it only uses gravity to fall, resulting in a slow flow rate, which affects the overall processing time and reduces work efficiency. In the initial state of use, the through holes inside the isolation plate 9 and the filter plate 2 are in a connected state. When it is necessary to drain the liquid inside the treatment tank 1... When the liquid is discharged, the motor 8 is first controlled by an external controller. When the motor 8 is running, it drives the isolation plate 9 to rotate. When the through hole inside the isolation plate 9 is misaligned with the through hole inside the filter plate 2, the motor 8 stops. At this time, the solenoid valve inside the liquid outlet 4 is opened, and the liquid inside the treatment tank 1 flows through the liquid outlet 4. Then, the cylinder 7 is controlled by the external controller to run. When the cylinder 7 is running, the output end of the cylinder 7 will push the filter plate 2 down through the motor 8. It should be noted that the external controller, cylinder 7 and motor 8 are all existing technologies and are mature, so they will not be elaborated on. The motor 8 is also waterproof. Because the through holes inside the filter plate 2 and the isolation plate 9 are misaligned, when the filter plate 2 moves down, it will squeeze the air inside the treatment tank 1. Under the action of air pressure, the liquid flow below the filter plate 2 can be accelerated, so that the liquid flows through the liquid outlet 4 to the designated position more quickly.

[0025] like Figure 3 As shown, a pair of limiting rods 10 are slidably connected inside the filter plate 2, and both ends of the pair of limiting rods 10 are fixedly connected to the inner wall of the treatment tank 1.

[0026] The setting of a pair of limit rods 10 can make the filter plate 2 more stable when it moves up and down. The limit rods 10 can prevent the filter plate 2 from shaking.

[0027] like Figure 5 and Figure 6 As shown, a diversion ring 11 is rotatably connected to the top of the inner wall of the treatment tank 1. A diversion groove 12 is provided at the bottom of the diversion ring 11. A ring plate 13 is rotatably connected inside the diversion ring 11. The liquid inlet 3 passes through the ring plate 13. A spur gear 14 is fixedly connected to the outside of the liquid inlet 3. A spur gear 2 15 is fixedly connected to the outside of the diversion ring 11. The spur gear 14 and the spur gear 2 15 mesh with each other. A power mechanism for driving the liquid inlet 3 to rotate is provided around the motor 5.

[0028] To prevent wastewater and additives from consistently falling at the same position on filter plate 2, thus causing excessive local pressure on filter plate 2, this invention, when the motor 5 drives the stirring rod 6 to mix the contents of the treatment tank 1, simultaneously drives the power mechanism. The power mechanism, in turn, rotates the inlet 3. The rotation of the inlet 3, in turn, drives the spur gear 14 to rotate the spur gear 15. The rotation of the spur gear 15 ultimately drives the diversion ring 11 to rotate. After entering the inlet 3, the wastewater and additives, under the influence of gravity, fall into the diversion ring 11 and then from the diversion ring 11 through the diversion channel 12 into the treatment tank 1. As the diversion ring 11 rotates continuously, the position of the diversion channel 12 is constantly adjusted, thereby changing the falling position of the wastewater and additives so that they can fall at different positions on the filter plate 2.

[0029] like Figure 5 and Figure 6 As shown, the power mechanism includes a transmission rod 16, a first chain 17, and a second chain 18. The transmission rod 16 is located around the processing tank 1. The first chain 17 is engaged with the output end of the motor 5 and the outside of the transmission rod 16. The second chain 18 is engaged with the transmission rod 16 and the outside of the liquid inlet 3.

[0030] When the motor 5 is running, it will drive the chain 17 to rotate. The rotation of the chain 17 will drive the chain 2 18 to rotate through the transmission rod 16. The rotation of the chain 2 18 will then drive the liquid inlet 3 to rotate, thus providing a power source for the rotation of the diversion ring 11.

[0031] like Figure 5 As shown, a pair of limiting rings 19 are rotatably connected to the outer side of the transmission rod 16, and the ends of the pair of limiting rings 19 away from the transmission rod 16 are fixedly connected to the outer side of the processing barrel 1.

[0032] The pair of limit rings 19 can stabilize the transmission rod 16 and prevent it from shaking when it rotates.

[0033] Working principle: In the initial state, the through holes inside the isolation plate 9 and the filter plate 2 are in a through state. When it is necessary to discharge the liquid inside the treatment tank 1, the motor 8 is first controlled by the external controller to run. When the motor 8 runs, it drives the isolation plate 9 to rotate. When the through hole inside the isolation plate 9 is misaligned with the through hole inside the filter plate 2, the motor 8 stops. At this time, the solenoid valve inside the liquid outlet 4 is opened, and the liquid inside the treatment tank 1 flows through the liquid outlet 4. Then, the cylinder 7 is controlled by the external controller to run. When the cylinder 7 runs, the output end of the cylinder 7 will push the filter plate 2 down through the motor 8. It should be noted that the external controller, cylinder 7 and motor 8 are all existing technologies and the technology is mature, so they will not be elaborated on. The motor 8 is waterproof. Because the through holes inside the filter plate 2 and the isolation plate 9 are misaligned, when the filter plate 2 moves down, it will squeeze the air inside the treatment tank 1. Under the action of air pressure, the liquid flow below the filter plate 2 can be accelerated, so that the liquid flows through the liquid outlet 4 to the designated position more quickly.

[0034] When motor 5 drives stirring rod 6 to mix the contents of treatment tank 1, motor 5 will simultaneously drive chain 17 to rotate. The rotation of chain 17 will drive chain 2 18 to rotate through transmission rod 16. The rotation of chain 2 18 will then drive inlet 3 to rotate. The rotation of inlet 3 will then drive spur gear 15 to rotate through spur gear 14. The rotation of spur gear 2 15 will eventually drive diversion ring 11 to rotate. After entering the contents of inlet 3, wastewater and additives will fall into the contents of diversion ring 11 under the action of gravity. From the contents of diversion ring 11, they will enter the contents of treatment tank 1 through diversion channel 12. As diversion ring 11 rotates continuously, the position of diversion channel 12 is also constantly adjusted, thereby changing the falling position of wastewater and additives so that they can fall at different positions on filter plate 2.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
