Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recycling, in particular to a high-efficiency treatment device for hydrometallurgical wastewater. Background Art

[0002] The high-efficiency hydrometallurgical wastewater treatment device is mainly used to treat complex wastewater generated in the hydrometallurgical process. It can effectively separate solid impurities in the wastewater and improve the wastewater purification effect. It is suitable for the treatment of wastewater with high suspended solids and complex components in the metallurgical industry, helping to achieve wastewater recycling and environmentally friendly emission goals.

[0003] A Chinese patent discloses a device for collecting and recycling industrial metallurgical wastewater (publication number CN209917449U). The patent includes a water collecting tank with rectangular through-grooves on both sides of the top of the water collecting tank. The interiors of the two rectangular through-grooves are connected to two heat exchange boxes via bolts. The tops of the two heat exchange boxes are provided with covers on both sides. The bottoms of the covers are connected to a housing via bolts. The interior of the housing is connected to a main filter screen via bolts. A secondary filter screen is connected to one side of the main filter screen via bolts.

[0004] Therefore, based on the above search and in combination with the existing, due to the complex composition of wastewater, the waste residue particles are of different sizes and properties. During the wastewater filtration process, small waste residue particles are easily embedded in the pores of the filtration equipment. As the processing volume increases, the waste residue continues to accumulate and eventually causes blockage. However, this patent cannot be cleaned during the operation of the equipment. Once the equipment is blocked by waste residue, it must be shut down for cleaning and maintenance, resulting in interruption of the wastewater treatment process, reduced production efficiency, affecting the overall production progress, and reducing the stability of subsequent wastewater treatment processes. It is not conducive to the overall continuous and efficient operation of the equipment. Frequent shutdowns for cleaning not only increase labor costs, but may also increase equipment wear and tear due to repeated start and stop of the equipment, shortening the equipment life and increasing equipment maintenance and replacement costs. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency treatment device for hydrometallurgical wastewater to solve the problems raised in the above background technology.

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

[0007] A high-efficiency treatment device for hydrometallurgical wastewater comprises a treatment box, the top of which is fixedly mounted with an injection pipe for injecting treatment liquid and an inlet pipe for injecting wastewater, and the bottom of which is fixedly mounted with an outlet pipe for discharging wastewater.

[0008] A partition plate is fixedly installed on the inner wall of the treatment box. The interior of the treatment box is divided by the partition plate to form an upper and lower chamber structure. The upper chamber in the treatment box serves as a reaction chamber for achieving sufficient contact and mixing reaction between wastewater and treatment liquid. The lower chamber in the treatment box serves as a separation and filtration chamber, and a filter plate for filtering wastewater is installed inside the chamber to effectively achieve solid-liquid separation.

[0009] The inner cavity of the filter plate is provided with a plurality of filter holes distributed in an array. The bottom of the filter plate is fixedly connected with an anti-blocking structure for preventing the filter plate from being blocked, and the anti-blocking structure is located in the lower cavity.

[0010] As a further solution of the present invention, the anti-blocking structure includes a guide plate, which is fixedly installed on the bottom end of the filter plate to guide the concentrated flow of wastewater. A rotating rod is rotatably installed on the top of the guide plate. The outer wall fixed sleeve of the rotating rod is provided with a driving blade for driving the rotating rod to rotate. The top rotating sleeve of the rotating rod is provided with a rotating sleeve. A connecting rod is fixedly installed on the top of the rotating sleeve. A pull rope is wrapped around the outside of the connecting rod, and the end of the pull rope is fixedly connected to a movable plate for changing the size of the filter hole.

[0011] As a further solution of the present invention, a rotating cover is rotatably sleeved on the outer wall of the top end of the connecting rod, and an annular groove is opened on its outer wall for limiting the pull rope, and the inner cavity of the rotating cover is clamped with an adjustment structure for preventing overload transmission.

[0012] As a further solution of the present invention, the adjustment structure includes a sliding block, which is slidably arranged in the inner cavity of the connecting rod. The sliding block is fixedly connected to a thrust spring on the side close to the connecting rod. The inner cavity of the rotating cover is provided with a slot, and the sliding block is engaged in the slot.

[0013] As a further solution of the present invention, two groups of collection boxes for collecting waste residue are symmetrically fixedly connected on both sides of the filter plate. The bottom end of each group of collection boxes is provided with a drainage hole for filtering waste water, and the two groups of collection boxes are fixedly connected to a sewage pipe for discharging waste residue on the side away from each other.

[0014] As a further solution of the present invention, a fixing frame is installed below the guide plate, and both ends of the fixing frame are fixedly connected to the collection box. A filter screen for further separating and filtering waste residues is fixedly installed inside the fixing frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the utility model is in use, the anti-blocking structure can utilize the kinetic energy of the wastewater itself as a power source without the need for additional energy. When the filter hole is blocked by waste residue, the filter hole size is automatically adjusted by driving the blade speed change, centrifugal force transmission and gravity action, and the blockage is cleared in time, avoiding shutdown maintenance due to blockage, ensuring uninterrupted operation of the wastewater treatment process, improving production efficiency, and providing stable protection for subsequent treatment processes.

[0017] 2. When the utility model is used, the sliding block of the adjustment structure is engaged and separated with the card slot, so that the connecting rod and the rotating cover slip and idle when the resistance of the pull rope is too large, thereby avoiding hard damage to the transmission parts and preventing deformation and fracture caused by stress concentration. When the water flow weakens, the thrust spring pushes the sliding block to reset, and cooperates with the reset spring to form double protection, reducing wear and tear caused by frequent start-stop of the equipment, ensuring stable operation of the anti-blocking structure, and reducing operation and maintenance costs.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1 、 Figure 2 A high-efficiency treatment device for hydrometallurgical wastewater comprises a treatment box 1, a top end of which is fixedly mounted an injection pipe 2 for injecting treatment liquid and an inlet pipe 3 for injecting wastewater, and a bottom end of which is fixedly mounted an outlet pipe 4 for discharging wastewater.

[0026] A partition plate 5 is fixedly installed on the inner wall of the treatment box 1. The interior of the treatment box 1 is divided by the partition plate 5 to form an upper and lower chamber structure. The upper chamber in the treatment box 1 serves as a reaction chamber for achieving full contact and mixed reaction between wastewater and treatment liquid. The lower chamber in the treatment box 1 is a separation and filtration chamber, and a filter plate 6 for filtering wastewater is installed inside it, which effectively realizes solid-liquid separation and intercepts and separates waste residue in the wastewater, thereby achieving the purpose of purifying the wastewater. The filter plate 6 is fixedly connected to the inner wall of the treatment box 1;

[0027] The inner cavity of the filter plate 6 is provided with a plurality of filter holes 7 distributed in an array. The bottom of the filter plate 6 is fixedly connected to an anti-blocking structure for preventing the filter plate 6 from being blocked. The anti-blocking structure is located in the lower chamber. The size of the filter holes 7 can be flexibly adjusted through the anti-blocking structure. When the filter holes 7 show signs of blocking, the aperture can be expanded in real time to ensure that the fluid can flow continuously, stably and unimpeded, thus achieving a dynamic balance between filtration efficiency and anti-blocking performance.

[0028] Specifically, the outer walls of the liquid injection pipe 2, the water inlet pipe 3 and the water outlet pipe 4 are all fixedly sleeved with a shut-off valve for achieving interception, which can achieve precise control of the injection of treated liquid, the input of wastewater and the output of purified wastewater, and is convenient for cutting off the pipeline fluid at any time to ensure operational safety and avoid liquid leakage and waste. A guide pipe 9 for guiding the flow of wastewater is fixedly installed at the center of the partition plate 5, and the top of the guide pipe 9 is set to an inverted cone, which can effectively guide the wastewater to flow evenly and dispersedly into the lower separation and filtration cavity, reduce water flow impact, and improve solid-liquid separation efficiency. The bottom end of the guide pipe 9 is close to the anti-blocking structure, and the outer wall of the guide pipe 9 is fixedly sleeved with a shut-off valve, which can control the inflow of upper wastewater to the lower layer as needed. A support column 10 is fixedly installed at the bottom end of the treatment box 1, and the support column 10 plays a role of stable support to ensure that the equipment remains stable during operation, avoids the internal treatment process affected by shaking, and extends the service life of the equipment.

[0029] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 The anti-blocking structure includes a guide plate 801, which is fixedly installed at the bottom end of the filter plate 6 to guide the concentrated flow of wastewater. A rotating rod 802 is rotatably installed on the top of the guide plate 801 through a bearing. The outer wall of the rotating rod 802 is fixedly sleeved with a driving blade 803 for driving the rotating rod 802 to rotate, which can convert the kinetic energy of the fluid into rotational power. A rotating sleeve 804 is provided on the top of the rotating rod 802 through a bearing. A connecting rod 805 is vertically fixedly installed on the top of the rotating sleeve 804. A pull rope 806 is wrapped around the outside of the connecting rod 805, and the end of the pull rope 806 is fixedly connected to a movable plate 807 for changing the size of the filter hole 7;

[0030] Specifically, the movable plate 807 can move linearly along the sliding channel opened inside the filter plate 6. By changing its relative position, the size of the filter hole 7 can be adjusted to accurately control the flow rate.

[0031] More specifically, a square groove for discharging wastewater is provided at the bottom end of the guide plate 801. A plurality of oblique water guide bars 808 are fixedly mounted on the upper surface of the guide plate 801 to guide the filtered wastewater to push the driving blade 803 with an inclined surface, thereby driving the rotating rod 802 to rotate. The kinetic energy of the wastewater is used to realize self-drive of the device. The connecting rod 805 and the pull rope 806 can rotate within the filter plate 6. The movable plate 807 has a built-in empty groove with the same diameter as the filter hole 7. Initially, the empty groove is misaligned with the filter hole 7 to keep the filter hole 7 in a minimum flow state.

[0032] When the filter holes 7 become clogged, less wastewater passes through the guide plate 801, which in turn reduces the speed of the driving blade 803. Combined with the inclination angle of the filter plate 6, the movable plate 807 contacts the pulling force of the blade rotation. Under the influence of gravity, the movable plate 807 slides down inside the filter plate 6, gradually aligning the empty slots with the filter holes 7, thereby expanding the filter holes 7, alleviating the blockage and ensuring that the wastewater can pass smoothly.

[0033] A transmission rod 809 is rotatably mounted in the inner cavity of the rotating sleeve 804, and the bottom end of the transmission rod 809 is coaxially fixedly connected to the rotating rod 802. Two moving blocks 810 are symmetrically slidably mounted in the inner cavity of the transmission rod 809. A transmission block 811 for driving the rotating sleeve 804 to rotate is fixedly mounted on one end of the two moving blocks 810 that is away from each other.

[0034] Specifically, the top end of the transmission rod 809 is rotatably connected to the inner wall of the rotating sleeve 804 via a bearing, and the top end of the rotating sleeve 804 is fixedly connected to the connecting rod 805. The rotation of the rotating sleeve 804 controls the extension and retraction of the pull rope 806. When the water flow drives the rotating rod 802 to rotate at high speed, the moving block 810 drives the transmission block 811 to move radially under the action of centrifugal force until a friction transmission surface is formed with the inner wall of the rotating sleeve 804, driving the rotating sleeve 804 to rotate synchronously.

[0035] More specifically, each moving block 810 is fixedly mounted with a fixing bolt 812 on both sides, and a return spring 813 is mounted on both sides of the transmission rod 809 for pulling the transmission block 811 back to its original position. Both ends of the return spring 813 are fixedly connected to the fixing bolt 812. When the water flow weakens, the return spring 813 pulls the moving block 810 to drive the transmission block 811 away from the rotating sleeve 804, so that the rotating sleeve 804 gradually releases the friction transmission.

[0036] The top outer wall of the connecting rod 805 is rotatably sleeved with a rotating cover 814, and an annular groove is opened on the outer wall for limiting the pull rope 806. The inner cavity of the rotating cover 814 is clamped with an adjustment structure for preventing overload transmission.

[0037] Example 2: Please refer to Figure 5 Based on Example 1, the adjustment structure includes a sliding block 815, which is slidably arranged in the inner cavity of the connecting rod 805. A thrust spring 817 is fixedly connected to the side of the sliding block 815 close to the connecting rod 805. A slot 816 is formed in the inner cavity of the rotating cover 814, and the sliding block 815 is engaged in the slot 816.

[0038] Specifically, when the resistance of the pull rope 806 reaches a preset threshold during the tightening process, the pulling force of the pull ropes 806 on both sides forces the rotating cover 814 to stop rotating. At this time, the inner wall of the rotating cover 814 will squeeze the sliding block 815, pushing it to overcome the elastic force of the thrust spring 817, allowing the sliding block 815 to disengage from the slot 816. This action instantly releases the limit on the rotating cover 814, allowing the connecting rod 805 to rotate freely inside the rotating cover 814, thereby preventing the pull rope 806 from being too tight and hindering the operation of the connecting rod 805, and preventing components from being damaged due to overload, thereby ensuring that the entire anti-blocking structure can continue to operate flexibly.

[0039] More specifically, when the wastewater discharge volume gradually decreases, the rotation speed of the connecting rod 805 will gradually decrease accordingly, allowing the thrust spring 817 to push the sliding block 815 back into the slot 816, and at the same time use the gravity and tilt angle of the movable plate 807 to achieve autonomous sliding, ensuring the stable operation of the device's circulation.

[0040] See also Figure 1 、 Figure 3 、 Figure 4, two groups of collection boxes 11 for collecting waste residue are symmetrically fixedly connected on both sides of the filter plate 6. The bottom end of each group of collection boxes 11 is provided with a drainage hole for filtering waste water. The two groups of collection boxes 11 are fixedly connected to the side away from each other with a sewage pipe 12 for discharging waste residue, and the outer wall of the sewage pipe 12 is fixedly provided with a shut-off valve for intercepting the flow;

[0041] A fixing frame 13 is installed below the guide plate 801, and both ends of the fixing frame 13 are fixedly connected to the collecting box 11. A filter screen 14 for further separating and filtering waste residue is fixedly installed inside the fixing frame 13, and a groove is provided on the side of the collecting box 11 close to the filter screen 14 to facilitate the flow of waste residue.

[0042] The working principle of this utility model is:

[0043] First, wastewater passes through the water inlet pipe 3 and the treatment liquid passes through the injection pipe 2 into the upper reaction chamber of the treatment box 1 to complete the chemical reaction and aggregate the waste residue particles;

[0044] The treated mixed liquid flows into the lower separation filter chamber through the bottom end of the guide tube 9, and the waste residue is intercepted by the filter holes 7 of the filter plate 6. The purified wastewater flows through the guide plate 801, and the inclined water guide bar 808 is used to guide the water flow to evenly impact the driving blade 803, driving the rotating rod 802 to rotate at high speed. The moving block 810 in the transmission rod 809 drives the transmission block 811 to expand outward due to centrifugal force, and the friction with the inner wall of the rotating sleeve 804 drives the rotating sleeve 804 and the connecting rod 805 to rotate. The pull rope 806 is tightened and pulls the movable plate 807 to maintain the minimum aperture of the filter hole 7.

[0045] When the filter hole 7 is clogged with waste residue, the water flow of the guide plate 801 is reduced, the speed of the driving blade 803 decreases, the centrifugal force weakens, the return spring 813 pulls the moving block 810 and the transmission block 811 to reset, and the rotating sleeve 804 stops driving. At this time, the inclined design of the filter plate 6 allows the moving plate 807 to slide down autonomously under the action of gravity, and the empty groove gradually aligns with the filter hole 7, the aperture is expanded, and the blockage is cleared;

[0046] At the same time, when the resistance to tightening the pull rope 806 is too great, the inner wall of the rotating cover 814 squeezes the sliding block 815, causing it to disengage from the slot 816, and the connecting rod 805 and the rotating cover 814 slip and rotate idly to avoid component damage. Conversely, when the water flow decreases, the thrust spring 817 pushes the sliding block 815 back into the slot 816, allowing the device to reset.

[0047] Finally, the purified wastewater is collected through the square groove of the guide plate 801, and then further separated into fine particles through the filter screen 14, and then discharged from the outlet pipe 4. The waste residue intercepted by the filter plate 6 slides along the inclined plate surface to the collection boxes 11 on both sides. After the waste residue is deposited, it is discharged through the shut-off valve of the sewage pipe 12.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
