Description

Technical Field

[0001] This utility model relates to the field of acidic wastewater recovery technology in abandoned mines, and in particular to a device for recovering valuable elements from acidic wastewater in abandoned mines. Background Technology

[0002] Acidic wastewater refers to wastewater with a pH value below 7. It usually originates from wastewater generated during the mining and processing of minerals and often contains sulfates, heavy metal ions, etc. Due to its acidic nature, this type of wastewater often contains a large number of harmful metal ions and other pollutants, which pose a significant threat to the environment and human health. Therefore, devices for recovering valuable elements from acidic wastewater from abandoned mines are used to achieve wastewater purification and resource recovery.

[0003] Existing devices for recovering valuable elements from acidic wastewater in abandoned mines operate by feeding the acidic wastewater into a treatment tank, adding a precipitant to neutralize it, and then filtering the neutralized wastewater through a filter plate. After the neutralization reaction is complete, stirring is stopped, and the wastewater is filtered through the filter plate, which retains the precipitate and valuable elements. The purified wastewater is then discharged through an outlet, thus completing the recovery of acidic wastewater.

[0004] However, after filtration, valuable elements and precipitates remain on the upper part of the filter plate and cannot be automatically recovered, resulting in ineffective recovery of valuable elements and waste of resources. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for recovering valuable elements from acidic wastewater from abandoned mines. It aims to improve the problem in the prior art where valuable elements and precipitates remain on the upper part of the filter plate after filtration and cannot be automatically recovered, resulting in ineffective recovery of valuable elements and waste of resources.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An apparatus for recovering valuable elements from acidic wastewater from abandoned mines includes a support frame. A treatment tank is fixedly connected to the upper part of the support frame. A mixing component is installed on the upper part of the treatment tank for mixing acidic wastewater and a precipitant. A conveying pipe is fixedly connected to the lower part of the treatment tank. A filter box is fixedly connected to the bottom of the conveying pipe. The filter box is fixedly connected to the middle of the support frame. A separation plate is installed inside the filter box. A horizontal plate is fixedly connected to the left side of the filter box. An electric push rod is installed at the lower part of the horizontal plate. The output end of the electric push rod is rotatably connected to a first connecting plate. A hinge block is installed on the front side of the horizontal plate. The left hinge block is fixedly connected to the outside of the horizontal plate, and the right hinge block is located on the front side of the outside of the horizontal plate. The other ends of the two first connecting plates are rotatably connected to the inside of the two hinge blocks. The inside of each of the two hinge blocks is rotatably connected to a second connecting plate. The other ends of the two second connecting plates are rotatably connected. A moving rod is fixedly connected to the outside of the right hinge block. A guide block is fixedly connected to the front side of the outside of the horizontal plate. The moving rod is slidably connected to the inside of the guide block. The other end of the moving rod passes through the inside of the filter box and is fixedly connected to an installation block. A push plate is installed under the installation block.

[0008] Furthermore, the mixing component includes a motor, a rotating rod fixedly connected to the output end of the motor, a first gear fixedly connected to the outside of the rotating rod, second gears meshing with both sides of the outside of the first gear, transmission rods fixedly connected inside the two second gears, stirring rods fixedly connected around the outside of the two transmission rods, a rotating disk fixedly connected to the bottom of the rotating rod, and scrapers fixedly connected around the outside of the rotating disk.

[0009] Furthermore, a sludge inlet is fixedly connected to the left side of the outside of the treatment tank, and a chemical dosing port is fixedly connected to the rear side of the outside of the treatment tank.

[0010] Furthermore, a mounting bracket is fixedly connected to the upper part of the processing tank, and the motor is fixedly connected inside the mounting bracket.

[0011] Furthermore, a control valve is installed on the outside of the delivery pipe.

[0012] Furthermore, both sides of the inside of the filter box are fixedly connected to fixing rods, and the mounting block is slidably connected to the outside of the two fixing rods.

[0013] Furthermore, a fixing ring is fixedly connected to the lower part of the cross plate, and the electric push rod is fixedly connected inside the fixing ring.

[0014] Furthermore, a guide plate is fixedly connected to the bottom of the filter box, a discharge port is fixedly connected to the right side of the outside of the filter box, a sealing plate is inserted into the discharge port, and a water outlet is fixedly connected to the lower right side of the filter box.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when recovering valuable elements remaining on the upper part of the separating plate, firstly, the sealing plate is removed from the discharge port using a pull ring. Then, the electric push rod is activated, causing the first connecting plate to move upward, which in turn pushes the second connecting plate to move within the left hinge block, causing the right hinge block to move to the right. As the right hinge block moves, the fixed moving rod slides within the guide block, causing the mounting block to move laterally along the fixed rod. The mounting block drives the lower push plate to push the valuable elements out of the discharge port, achieving automatic recovery, avoiding residue of valuable elements, ensuring full utilization, reducing resource waste, and improving efficiency.

[0017] 2. In this invention, when treating acidic wastewater, the wastewater is first transported into the treatment tank through the inlet, and then a precipitant is added through the dosing port. The motor is started, driving the rotating rod and the fixed first gear to rotate. The meshing second gear drives the transmission rod and the stirring rod to rotate, ensuring thorough mixing of the acidic wastewater and the precipitant, thus accelerating the reaction. Simultaneously, the rotating disc drives a scraper to move along the inner wall of the tank, scraping away any adhering substances. This ensures that the precipitant reacts fully with the acidic wastewater, improving treatment efficiency. Attached Figure Description

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.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a device for recovering valuable elements from acidic wastewater from abandoned mines. The device includes a support 1, a treatment tank 2 fixedly connected to the upper part of the support 1, a mixing component 6 installed on the upper part of the treatment tank 2 for mixing the acidic wastewater and a precipitant, a conveying pipe 7 fixedly connected to the lower part of the treatment tank 2, a filter box 9 fixedly connected to the bottom of the conveying pipe 7, and the filter box 9 fixedly connected to the middle of the support 1. A separation plate 10 is installed inside the filter box 9. A horizontal plate 15 is fixedly connected to the left side of the filter box 9. An electric push rod 17 is installed at the lower part of the horizontal plate 15. The output ends of the electric push rod 17 are rotatably connected to first connecting plates 19. Hinge blocks 18 are installed on the front side of the horizontal plate 15. The left hinge block 18 is fixedly connected to the outside of the horizontal plate 15, and the right hinge block 18 is located on the front side of the horizontal plate 15. The other ends of the two first connecting plates 19 are rotatably connected to the inside of the two hinge blocks 18. A second connecting plate 20 is rotatably connected to the inside of each of the two hinge blocks 18. The other ends of the two second connecting plates 20 are rotatably connected. A moving rod 21 is fixedly connected to the outside of the right hinge block 18. A guide block 22 is fixedly connected to the front of the outside of the horizontal plate 15. The moving rod 21 is slidably connected inside the guide block 22. The other end of the moving rod 21 passes through the inside of the filter box 9 and is fixedly connected to the mounting block 23. A push plate 24 is installed under the mounting block 23. A control valve 8 is installed outside the conveying pipe 7. Fixed rods 25 are fixedly connected to both sides inside the filter box 9. The mounting block 23 is slidably connected to the outside of the two fixed rods 25. A fixed ring 16 is fixedly connected to the lower part of the horizontal plate 15. An electric push rod 17 is fixedly connected inside the fixed ring 16. A guide plate 13 is fixedly connected to the bottom inside the filter box 9. An outlet 11 is fixedly connected to the right side of the outside of the filter box 9. A sealing plate 12 is inserted inside the outlet 11. An outlet 14 is fixedly connected to the right side of the lower part of the filter box 9. An inlet 3 is fixedly connected to the left side of the outside of the treatment tank 2. A dosing port 4 is fixedly connected to the rear side of the outside of the treatment tank 2.

[0027] When it is necessary to recover valuable elements remaining on the upper part of the separating plate 10, firstly, the sealing plate 12 is removed from the inside of the discharge port 11 by pulling the ring on the upper part of the sealing plate 12. After removing the sealing plate 12, the electric push rod 17 is activated, and the electric push rod 17 starts to operate, driving the two first connecting plates 19 rotatably connected at its output end to move upward. As the first connecting plates 19 move upward, they further drive the two second connecting plates 20 rotatably connected at the other end to move relative to each other inside the left hinge block 18. The relative movement of the first connecting plates 19 and the second connecting plates 20 causes the right hinge block 18 rotatably connected at the other end to move to the right. The movement of the right hinge block 18 further drives the externally fixed moving rod 21 to move smoothly inside the guide block 22. During the movement of the moving rod 21, the mounting block 23 fixed to the other end of the moving rod 21 also moves laterally outside the two fixed rods 25 along with the movement of the moving rod 21. The lateral movement of the mounting block 23 drives the push plate 24 mounted below it to move synchronously. During its movement, the pusher plate 24 pushes out the valuable elements remaining on the upper part of the separation plate 10 from the inside of the discharge port 11, realizing an automated recycling process. This ensures that all valuable elements on the upper part of the separation plate 10 can be effectively recycled, thus avoiding the residue of valuable elements. Through automatic recycling, all valuable elements are fully recovered and utilized, minimizing resource waste and improving resource utilization efficiency. At the same time, the automated recycling process not only improves recycling efficiency but also reduces the need for manual operation, reduces labor costs, and improves overall production efficiency. The addition port 4 facilitates the addition of precipitant.

[0028] Reference Figure 3 and Figure 5 The mixing component 6 includes a motor 601, a rotating rod 602 fixedly connected to the output end of the motor 601, a first gear 603 fixedly connected to the outside of the rotating rod 602, second gears 604 meshing with both sides of the outside of the first gear 603, transmission rods 605 fixedly connected inside the two second gears 604, stirring rods 606 fixedly connected around the outside of the two transmission rods 605, a rotating disk 607 fixedly connected to the bottom of the rotating rod 602, scrapers 608 fixedly connected around the outside of the rotating disk 607, a mounting frame 5 fixedly connected to the upper part of the processing tank 2, and the motor 601 fixedly connected inside the mounting frame 5.

[0029] In the treatment of acidic wastewater, the acidic wastewater is first transported into the treatment tank 2 through the inlet 3. After entering the treatment tank 2, an appropriate amount of precipitant is added into the treatment tank 2 through the dosing port 4. Then, the motor 601 is started, which drives the rotating rod 602 fixed at its output end to rotate. The rotation of the rotating rod 602 further drives the first gear 603 fixed on its outside to rotate. As the first gear 603 rotates, the second gears 604 meshing on both sides of its outside also begin to rotate synchronously. During the rotation of the two second gears 604, they drive the two transmission rods 605 fixed inside to rotate. The rotation of the transmission rods 605 acts on the stirring rods 606 fixed around its outside, causing the stirring rods 606 to perform a thorough stirring motion inside the treatment tank 2. Through the rotation of the stirring rods 606, the acidic wastewater and the added precipitant inside the treatment tank 2 are thoroughly mixed. This process accelerates the chemical reaction rate between the precipitant and the acidic components in the acidic wastewater, thereby significantly improving the efficiency of wastewater treatment. As the rotating rod 602 rotates, the rotating disk 607 fixed at its bottom also rotates. The rotation of the rotating disk 607 drives the scrapers 608 fixed around its outer perimeter to move against the inner wall of the treatment tank 2. During this movement, the scrapers 608 effectively scrape away substances adhering to the inner wall of the tank, preventing these substances from accumulating and affecting treatment efficiency and equipment lifespan. This ensures thorough mixing of the acidic wastewater and precipitant inside the treatment tank 2 during the acidic wastewater treatment process. Thorough mixing ensures that the precipitant can fully react with the acidic components in the wastewater, thereby accelerating the chemical reaction rate and significantly improving treatment efficiency. At the same time, the cleaning action of the scrapers 608 ensures the cleanliness of the inner wall of the treatment tank 2, maintaining the normal operation of the equipment.

[0030] Working principle: When it is necessary to recover valuable elements remaining on the upper part of the separation plate 10, firstly, the sealing plate 12 is removed from the inside of the discharge port 11 by the pull ring on the upper part of the sealing plate 12. Then, the electric push rod 17 is activated. The electric push rod 17 moves the two first connecting plates 19 rotatably connected at the output end upward. The movement of the two first connecting plates 19 causes the two second connecting plates 20 rotatably connected at the other end to move relative to each other inside the left hinge block 18. The relative movement of the two first connecting plates 19 and the two second connecting plates 20 causes the right hinge block 18 rotatably connected at the other end to move to the right. The moving rod 21, which is fixed externally, moves inside the guide block 22. As the moving rod 21 moves, it also moves laterally outside the two fixed rods 25, carrying the mounting block 23, which is fixed at the other end. As the mounting block 23 moves, it also moves the push plate 24 mounted on its lower part. The push plate 24 pushes out the valuable elements remaining on the upper part of the separating plate 10 from inside the discharge port 11. This achieves automatic recovery of valuable elements remaining on the upper part of the separating plate 10, preventing them from remaining there and ensuring that all valuable elements are fully recovered and utilized, minimizing resource waste and improving resource efficiency. To maximize efficiency, in the treatment of acidic wastewater, firstly, the acidic wastewater is transported into the treatment tank 2 through the inlet 3. Then, a flocculant is added into the treatment tank 2 through the dosing port 4. Next, the motor 601 is started. The motor 601 drives the rotating rod 602 fixed at the output end to rotate. The rotation of the rotating rod 602 drives the externally fixed first gear 603 to rotate. The rotation of the first gear 603 drives the externally meshed second gears 604 to rotate. The rotation of the two second gears 604 drives the two internally fixed transmission rods 605 to rotate. The rotation of the two transmission rods 605 drives the externally fixed stirring rods. The rotation of the stirring rod 606 ensures thorough mixing of the acidic wastewater and precipitant inside the treatment tank 2, accelerating the reaction rate. Simultaneously, the rotation of the rotating rod 602 causes the rotating disk 607, fixed at its bottom, to rotate. The rotating disk 607, in turn, moves the scrapers 608, fixed around its perimeter, against the inner wall of the treatment tank 2, scraping away any substances adhering to the tank's inner wall. This facilitates thorough mixing of the acidic wastewater and precipitant inside the treatment tank 2 during the treatment of acidic wastewater, ensuring a complete reaction between the precipitant and the acidic components in the wastewater, accelerating the chemical reaction rate, and thus improving treatment efficiency.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
