Description

Technical Field

[0001] This invention relates to the field of recycling equipment technology, and in particular to an equipment for recovering valuable elements from acidic wastewater from abandoned mines. Background Technology

[0002] Copper plays a vital role in national economic life and industrial production. However, copper mining and production processes generate large amounts of copper-containing wastewater. If discharged into the environment without treatment, copper ions can cause harm to human health through water migration, soil accumulation, and the food chain, leading to symptoms such as abdominal pain, vomiting, and even cirrhosis. Furthermore, given the high economic value of copper, directly discharging copper ions from copper mine wastewater without recovery would result in significant resource waste.

[0003] Existing recycling devices require filtering residues during recycling, and the residues need to be removed after filtration. During the residue removal process, gas leakage from the wastewater is severe, affecting the health of workers. In wastewater treatment, additives are required for decomposition, but during the decomposition process, it is not possible to achieve sufficient mixing of wastewater and additives through multiple mixing structures.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a device for recovering valuable elements from acidic wastewater from abandoned mines, in order to achieve a more practical purpose. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a device for recovering valuable elements from acidic wastewater from abandoned mines. This solves the problems of existing recovery devices that require filtering residues during recovery, and then removing the residues after filtration. During the residue removal process, significant gas leakage from the wastewater occurs, affecting the health of workers. Furthermore, wastewater treatment requires the use of additives for decomposition, but during the decomposition process, it is impossible to achieve sufficient mixing of wastewater and additives through multiple mixing structures.

[0006] This invention provides a device for recovering valuable elements from acidic wastewater from abandoned mines, specifically comprising: a treatment tank; a top cover fixed to the top of the treatment tank, on which a pipe for adding wastewater and an additive funnel are welded; a bottom cover fixed to the bottom of the treatment tank; a filter screen holder fixed inside the treatment tank, on which an iron filter screen is fixed; a threaded rod rotating on the treatment tank; a second motor fixed to the left end face of the treatment tank, the output shaft of the second motor fixed to the threaded rod; a rectangular block-shaped fixing block threadedly connected to the threaded rod, the front and rear faces of the fixing block contacting the front and rear faces of the inner wall of the treatment tank, respectively; two second electric cylinders fixed to the bottom face of the fixing block, the protruding ends of the two second electric cylinders being fixed to a cleaning brush, the cleaning brush contacting the top face of the filter screen holder.

[0007] Furthermore, a sealing assembly is installed on the processing box. The sealing assembly consists of a second spring rod and a first sealing plate. Two second spring rods are fixed on the processing box, and the lower end of each of the two second spring rods is fixed to the first sealing plate. The first sealing plate is a rectangular plate structure, and the size of the first sealing plate is the same as that of the slag discharge port of the processing box.

[0008] Furthermore, after the two second spring rods have fully extended, the first sealing plate is located at the slag discharge port on the processing box, at which point the slag discharge port is sealed.

[0009] Furthermore, a collection assembly is fixed on the processing box. The collection assembly consists of a collection box, a second sealing plate, and a force-bearing block. A second sealing plate is rotatably mounted on the collection box. A coil spring is installed on the processing box for the second sealing plate to rotate clockwise and close. When the second sealing plate closes under the drive of the coil spring, the processing box is in a sealed state.

[0010] Furthermore, two force-bearing blocks are welded to the top surface of the second sealing plate. Both force-bearing blocks are right-angled trapezoidal block structures. The top of both force-bearing blocks are in elastic contact with the bottom surface of the first sealing plate. The elastic force of the coil spring is greater than the elastic force of the two second spring rods.

[0011] Furthermore, when the cleaning brush moves to the right, it comes into contact with the inclined surfaces of the two force-bearing blocks.

[0012] Furthermore, a mixing assembly is installed on the processing box. The mixing assembly consists of a rotating shaft, an impeller, a first motor, a mounting block, a first spring rod, and an auxiliary plate. A rotating shaft rotates on the processing box, and an impeller is fixed on the rotating shaft. A first motor is fixed on the rear end face of the processing box, and the output shaft of the first motor is fixed on the rotating shaft.

[0013] Furthermore, a mounting block is fixed to both the left and right end faces of the inner wall of the processing box, and two first spring rods are fixed to the top face of each mounting block. The protruding ends of the four first spring rods are fixed to the auxiliary plate.

[0014] Furthermore, the impeller is in elastic contact with the auxiliary plate, and the auxiliary plate reciprocates up and down when the impeller rotates.

[0015] Furthermore, a blocking assembly is installed on the processing box. The blocking assembly consists of blocking blocks, first electric cylinders, and blocking plates. A blocking block is fixed on both the left and right end faces of the inner wall of the processing box. The two blocking blocks are located below the mounting block. The front and rear faces of the two blocking blocks are in contact with the front and rear faces of the inner wall of the processing box, respectively. Two first electric cylinders are fixed on both the left and right end faces of the inner wall of the processing box. A blocking plate is fixed to the extended end of the two first electric cylinders on the left side, and a blocking plate is also fixed to the extended end of the two first electric cylinders on the right side. The top faces of the two blocking plates are in contact with the bottom faces of the two blocking blocks, respectively. When the four first electric cylinders extend, the inner sides of the two blocking plates contact each other. At this time, the interior of the processing box is divided into two areas.

[0016] Furthermore, both of the aforementioned blocking blocks are right-angled triangular block structures.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Highly efficient debris cleaning and filtration: Automatic cleaning of debris from the filter screen is achieved through a threaded rod, a second motor, a fixed block, a second electric cylinder, and a cleaning brush. The cleaning brush not only moves to the right under the drive of the threaded rod, pushing residue from the filter screen to the right, but can also be adjusted downwards by the extension of the second electric cylinder to ensure effective cleaning.

[0019] Flexible sealing and slag discharge mechanism: The sealing assembly consists of a second spring rod and a first sealing plate, which can seal the slag discharge port of the processing box under the elastic force of the second spring rod to prevent gas leakage.

[0020] The collection assembly consists of a collection box, a second sealing plate, and a force-bearing block. When the cleaning brush moves to the right, it squeezes the force-bearing block, causing the second sealing plate to rotate, thereby opening the slag discharge port. The residue slides into the collection box, achieving flexible slag discharge. After the collection box is removed, the second sealing plate can automatically seal under the action of the coil spring to prevent the gas inside the residue from leaking out.

[0021] Optimized mixing effect: The mixing component consists of a rotating shaft, impeller, first motor, mounting block, first spring rod, and auxiliary plate. The first motor drives the impeller to rotate, achieving thorough mixing of wastewater and additives. The auxiliary plate moves up and down reciprocatingly under the elastic force of the first spring rod, further enhancing the mixing effect and improving extraction efficiency.

[0022] Convenient partitioning and recycling of valuable elements: The blocking assembly consists of a blocking block, a first electric cylinder, and a blocking plate. By controlling the extension of the first electric cylinder, the interior of the processing box can be divided into two areas.

[0023] When valuable elements are removed from the bottom cover, two baffles separate the treatment tank, allowing the separated wastewater to be decomposed again, thus improving resource utilization.

[0024] The baffles are designed with a right-angled triangular block structure, which avoids the residue of sediment on the two baffles and keeps the equipment clean and efficient. Attached Figure Description

Example

[0046] As attached Figure 1 To be continued Figure 8 As shown:

[0047] This invention provides a device for recovering valuable elements from acidic wastewater from abandoned mines, comprising: a processing tank 1; a top cover 101 fixed to the top of the processing tank 1, on which a pipe for adding wastewater and an additive funnel are welded; a bottom cover 102 fixed to the bottom of the processing tank 1; a filter screen holder 4 fixed inside the processing tank 1, on which an iron filter screen is fixed; a threaded rod 701 rotatably mounted on the processing tank 1; a second motor 702 fixed to the left end face of the processing tank 1, the output shaft of the second motor 702 fixed to the threaded rod 701; and a rectangular block structure threadedly connected to the threaded rod 701. The fixing block 703 has its front and rear faces in contact with the front and rear faces of the inner wall of the processing box 1, respectively. Two second electric cylinders 704 are fixed to the bottom face of the fixing block 703. The extended ends of the two second electric cylinders 704 are fixed to the cleaning brush 705. The cleaning brush 705 is in contact with the top face of the filter screen holder 4. When cleaning debris, the second motor 702 is controlled to rotate. Driven by the threaded rod 701, the cleaning brush 705 moves to the right. At this time, the residue on the filter screen can be pushed to the right. When the cleaning brush 705 is worn, the two second electric cylinders 704 are controlled to extend. At this time, the downward adjustment compensation of the cleaning brush 705 can be realized.

[0048] The treatment box 1 is equipped with a sealing assembly 5, which consists of a second spring rod 501 and a first sealing plate 502. Two second spring rods 501 are fixed on the treatment box 1, and the lower end of each of the two second spring rods 501 is fixed on the first sealing plate 502. The first sealing plate 502 is a rectangular plate structure and is the same size as the slag discharge port of the treatment box 1.

[0049] When the two second spring rods 501 are fully extended, the first sealing plate 502 is located at the slag discharge port on the processing box 1. At this time, the slag discharge port is in a sealed state, which can prevent gas leakage after the slag discharge port is sealed.

[0050] The processing box 1 is fixed with a collection component 6, which consists of a collection box 601, a second sealing plate 602 and a force-bearing block 603. A second sealing plate 602 is rotatably mounted on the collection box 601. A coil spring is installed on the processing box 1 for the second sealing plate 602 to rotate clockwise to close. When the second sealing plate 602 is closed under the drive of the coil spring, the processing box 1 is in a sealed state.

[0051] Two force-bearing blocks 603 are welded to the top surface of the second sealing plate 602. Both force-bearing blocks 603 are right-angled trapezoidal block structures. The top of both force-bearing blocks 603 are in elastic contact with the bottom surface of the first sealing plate 502. The elastic force of the coil spring is greater than the elastic force of the two second spring rods 501. During use, when the collection box 601 is removed, the first sealing plate 502 moves downward under the push of the elastic force of the second spring rods 501 to complete the sealing of the processing box 1.

[0052] When the cleaning brush 705 moves to the right, it comes into contact with the inclined surfaces of the two force blocks 603. Under the pressure of the cleaning brush 705, the second sealing plate 602 rotates. At this time, the cleaning brush 705 pushes the debris onto the second sealing plate 602, and the residue slides down from the second sealing plate 602 into the collection box 601.

[0053] The treatment tank 1 is equipped with a mixing component 2, which consists of a rotating shaft 201, an impeller 202, a first motor 203, a mounting block 204, a first spring rod 205, and an auxiliary plate 206. A rotating shaft 201 rotates on the treatment tank 1, and an impeller 202 is fixed on the rotating shaft 201. A first motor 203 is fixed to the rear end face of the treatment tank 1, and the output shaft of the first motor 203 is fixed on the rotating shaft 201. During mixing, the first motor 203 is controlled to rotate, and the first motor 203 drives the impeller 202 to rotate, which can achieve full mixing of wastewater additives in the treatment tank 1 and improve the extraction effect.

[0054] Among them, a mounting block 204 is fixed on the left end face and the right end face of the inner wall of the processing box 1. Two first spring rods 205 are fixed on the top face of each mounting block 204. The protruding ends of the four first spring rods 205 are fixed on the auxiliary plate 206.

[0055] The impeller 202 is in elastic contact with the auxiliary plate 206. When the impeller 202 rotates, the auxiliary plate 206 moves up and down in a reciprocating motion. While the impeller 202 rotates to achieve mixing, the wastewater and additives can be mixed again through the up and down reciprocating movement of the auxiliary plate 206, thus improving the mixing effect.

[0056] The processing box 1 is equipped with a blocking assembly 3, which consists of blocking blocks 301, first electric cylinders 302, and blocking plates 303. A blocking block 301 is fixed to both the left and right end faces of the inner wall of the processing box 1. The two blocking blocks 301 are located below the mounting block 204, and their front and rear faces respectively contact the front and rear faces of the inner wall of the processing box 1. Two first electric cylinders 302 are fixed to both the left and right end faces of the inner wall of the processing box 1. A blocking plate 303 is fixed to the extended end of the two first electric cylinders 302 on the left side, and a blocking plate 303 is fixed to the extended end of the two first electric cylinders 302 on the right side. A baffle plate 303 is also fixed to the extended end of the electric cylinder 302. The top surfaces of the two baffle plates 303 are in contact with the bottom surfaces of the two baffle blocks 301 respectively. When the four first electric cylinders 302 extend, the inner sides of the two baffle plates 303 are in contact. At this time, the inside of the treatment box 1 is divided into two areas. When the valuable elements on the bottom cover 102 are taken out, the four first electric cylinders 302 are controlled to extend. At this time, the two baffle plates 303 complete the separation of the treatment box 1. After separation, the bottom cover 102 is removed. At this time, the valuable elements on the bottom cover 102 can be taken out. The sewage above the baffle plate 303 can be decomposed again. Example

[0057] Based on Embodiment 1, it also includes: both blocking blocks 301 are right-angled triangular block structures, which can prevent sediment from remaining on the two blocking blocks 301 during use.

[0058] The specific usage and function of this embodiment are as follows:

[0059] Wastewater and additives are added through the top cover 101. During debris removal, the second motor 702 is rotated, and the cleaning brush 705 moves to the right under the drive of the threaded rod 701. This pushes the residue on the filter screen to the right. Under the pressure of the cleaning brush 705, the second sealing plate 602 rotates, pushing the debris onto it. The residue then slides down from the second sealing plate 602 into the collection box 601. When the cleaning brush 705 wears down, the two second electric cylinders 704 are extended, allowing for downward adjustment and compensation of the cleaning brush 705. During mixing, the first motor 203 is rotated, driving the impeller 202 to rotate. The impeller 202 rotates to achieve thorough mixing of the wastewater and additives in the treatment tank 1, improving the extraction effect. At the same time, while the impeller 202 rotates to achieve mixing, the wastewater and additives are mixed again by the up-and-down reciprocating movement of the auxiliary plate 206, improving the mixing effect. After mixing, sedimentation is required. After sedimentation, the four first electric cylinders 302 are extended, and the two baffle plates 303 separate the treatment tank 1. After separation, the bottom cover 102 is removed, and the valuable elements on the bottom cover 102 can be extracted. When collecting residue, after the collection tank 601 is removed, the first sealing plate 502 moves downward under the elastic force of the second spring rod 501 to seal the treatment tank 1.
