Description

Technical Field

[0001] This utility model relates to the field of waste acid treatment in mineral processing, and more specifically, to a waste acid recovery and pretreatment device for ore testing. Background Technology

[0002] In the beneficiation and smelting process of lead-zinc ore, a large amount of waste acid is often generated, which mainly contains dissolved heavy metal ions (such as lead, zinc, iron, cadmium, arsenic, etc.), primarily lead and zinc. Due to its high acidity and toxicity, direct discharge of this type of waste acid will seriously pollute the soil and water bodies and cause resource waste. When treating waste acid in an environmentally friendly manner, recovering valuable metals from the acid can reduce the risk of environmental pollution and reduce resource waste.

[0003] In the prior art, the prior art with announcement number CN223175925U discloses a pretreatment device for the recycling of waste acid from ore testing. Although this prior art, by setting up a separation component including a first recovery mechanism and a second recovery mechanism, and cooperating with a detection and control module with a pH sensor, can precipitate and collect different metal hydroxides such as lead and zinc in stages according to the different pH values ​​in the treatment tank, in actual industrial continuous production or large-scale testing scenarios, the capacity of the recovery tank in this prior art is fixed. When the metal precipitate in a recovery mechanism reaches full capacity, the liquid feeding must be stopped, and the recovery mechanism can only be put back into operation after cleaning and slag removal. During this cleaning period, the entire pretreatment process has to be interrupted, and the interruption time depends on the processing time and installation time of the recovery tank, resulting in the inability to treat the subsequent waste acid in a timely manner, affecting the continuity of overall production and processing efficiency. In view of this, we propose a waste acid recycling pretreatment device for ore testing to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a waste acid recovery and pretreatment device for ore testing, comprising a treatment box, two separation boxes fixedly connected to the surface of the treatment box, two assembly slots opened inside the separation boxes, a recovery box arranged inside the assembly slots, filter holes opened on the bottom wall of the recovery box, a pump body fixedly connected to the front surface of the treatment box, a connecting pipe fixedly connected to the output end of the pump body, and the input end of the pump body connected to the interior of the treatment box through a pipe, a first fixing plate fixedly connected to the surface of the separation boxes, the first fixing plate being fixedly sleeved on the outside of the connecting pipe, a second fixing plate fixedly connected to the surface of the separation boxes, a rotating tube rotatably sleeved inside the second fixing plate, a transmission assembly arranged outside the rotating tube, and a fixing assembly arranged outside the separation boxes.

[0006] As a preferred technical solution of this application, a rotating flange is provided between the rotating pipe and the connecting pipe.

[0007] As a preferred technical solution of this application, the bottom walls of both assembly slots are provided with guide channels, the separation box is connected to the interior of the treatment box through the guide channels, and the other end of the rotating pipe is provided with a water outlet.

[0008] As a preferred technical solution of this application, the fixing component includes four guide blocks, all four guide blocks are fixedly connected to the surface of the separation box, and a transverse plate is slidably connected inside the four guide blocks. Both ends of the transverse plate are fixedly connected to a connecting plate, and a locking block is fixedly connected to one of the adjacent surfaces of the two connecting plates.

[0009] As a preferred technical solution of this application, through grooves are provided on both sides of the separation box, and slots are provided on the opposite sides of the two recycling boxes. The slots and through grooves are adapted to the locking block.

[0010] As a preferred technical solution of this application, adjusting screws are rotatably connected to opposite sides of the two separation boxes, and the connecting plates on both sides are threaded onto the outside of the two adjusting screws.

[0011] As a preferred technical solution of this application, the transmission assembly includes a driven gear, which is fixedly sleeved on the outside of the rotating tube, and a transmission shaft is rotatably connected to the upper surface of the second fixed plate. A transmission gear is fixedly connected to the upper end of the transmission shaft, and the transmission gear and the driven gear are meshed together.

[0012] As a preferred technical solution of this application, the surface of the transverse plate is provided with toothed grooves, and the transmission gear is meshed with the transverse plate through the toothed grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. By setting two interchangeable recovery boxes in each separation box, when one recovery box is full of filter residue, the sediment conveying path can be switched to another empty recovery box in the same separation box. The full box that is switched off can be cleaned, thus solving the problem of production interruption caused by the need to stop the machine for cleaning when a single recovery box is full. This greatly improves the overall operating efficiency and continuity of the waste acid pretreatment device, and is especially suitable for the needs of large-scale and continuous industrial production.

[0016] 2. Through the coordination of structures such as the adjusting screw, connecting plate, transverse plate, locking block, toothed groove, transmission gear, and driven gear, the system enables the simultaneous unlocking of the full-capacity recovery tank and the locking of the empty standby recovery tank by simply rotating the adjusting screw. It also drives the rotating pipe to accurately rotate the water outlet head above the standby recovery tank, integrating the tank fixing and pipeline switching actions. This simplifies the operation process, reduces the complexity and time cost of manual operation, facilitates rapid switching, and further ensures production continuity. Attached Figure Description

[0028] Example 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5A waste acid recovery and pretreatment device for ore testing includes a treatment tank 1. Two separation tanks 2 for classifying filter residue are fixedly connected to the surface of the treatment tank 1. Since the two separation tanks 2 have identical structures, the following description focuses on the structure of one separation tank 2. Two assembly slots 3 are provided inside the separation tank 2. A recovery tank 5 for collecting filter residue is installed inside the assembly slots 3. Filter holes 6 are provided on the bottom wall of the recovery tank 5. The arrangement of the recovery tank 5 and filter holes 6 facilitates the collection of filter residue. A pump body 7 for providing power is fixedly connected to the front surface of the treatment tank 1. A connecting pipe 8 for conveying solution is fixedly connected to the output end of the pump body 7. The input end of pump body 7 is connected to the interior of processing tank 1 through a pipe, and the two pump bodies 7 are connected to the interior of processing tank 1 at different heights. This facilitates the collection of different precipitates into different separation tanks 2 by taking advantage of the different precipitation rates of different metal ions at different pH values. A first fixing plate 9 for support is fixedly connected to the surface of separation tank 2. The first fixing plate 9 is fixedly sleeved on the outside of connecting pipe 8. A second fixing plate 10 for support is fixedly connected to the surface of separation tank 2. A rotating tube 11 for rotation is rotatably sleeved inside the second fixing plate 10. A transmission component is provided on the outside of the rotating tube 11. A fixing component is provided on the outside of separation tank 2.

[0030] Inside the processing tank 1, a stirring element and a pH sensor are also installed. Since these are conventional technologies in the field, they will not be described in detail here.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a rotating flange 24 is provided between the rotating pipe 11 and the connecting pipe 8 for connection. The rotating flange 24 ensures both the sealing of the connection between the rotating pipe 11 and the connecting pipe 8 and the stability of the rotation of the rotating pipe 11.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the bottom walls of both assembly tanks 3 are provided with guide channels 4. The separation tank 2 is connected to the interior of the treatment tank 1 through the guide channels 4. The other end of the rotating pipe 11 is provided with a water outlet 12. The filtered solution is easily transported back to the interior of the treatment tank 1 through the guide channels 4.

[0033] Example 2

[0034] The waste acid recovery and pretreatment device for ore testing provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the fixing assembly includes four guide blocks 13 for limiting the movement trajectory of the structure. All four guide blocks 13 are fixedly connected to the surface of the separation box 2. The interior of the four guide blocks 13 is slidably connected to a transverse plate 14 for sliding. Both ends of the transverse plate 14 are fixedly connected to a connecting plate 15. On the adjacent side surfaces of the two connecting plates 15, a locking block 16 for fixing the recycling box 5 is fixedly connected. The movement of the transverse plate 14 can drive the movement of the connecting plate 15, and the movement of the connecting plate 15 can drive the movement of the locking block 16.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, both sides of the separation box 2 are provided with sliding grooves 18, and the opposite sides of the two recycling boxes 5 are provided with slots 17 for cooperating with locking blocks 16. The slots 17 and the grooves 18 are adapted to the locking blocks 16. The locking blocks 16 can be moved by the connecting plate 15, so that the locking blocks 16 can move inside the slots 17 and the grooves 18. Thus, when the locking blocks 16 are located inside the slots 17, the corresponding recycling box 5 can be fixed.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the two separation boxes 2 are rotatably connected to the opposite side surfaces of each other, and the connecting plates 15 on both sides are threaded onto the outside of the two adjusting screws 19. By rotating the adjusting screws 19, the connecting plates 15 can be moved, which in turn moves the transverse plate 14.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the transmission assembly includes a driven gear 20 for rotation. The driven gear 20 is fixedly sleeved on the outside of the rotating tube 11, and a transmission shaft 21 for support is rotatably connected to the upper surface of the second fixed plate 10. A transmission gear 22 is fixedly connected to the upper end of the transmission shaft 21. The transmission gear 22 and the driven gear 20 are meshed together. The rotation of the transmission gear 22 can drive the rotation of the driven gear 20, which in turn drives the rotation of the rotating tube 11, ultimately causing the end of the rotating tube 11 to face another recycling box 5.

[0038] Furthermore, such as Figure 1 , Figure 2, Figure 3 , Figure 4 , Figure 5 As shown, the surface of the transverse plate 14 is provided with a toothed groove 23. The transmission gear 22 is connected to the transverse plate 14 through the toothed groove 23. The movement of the transverse plate 14 can drive the rotation of the transmission gear 22.

[0039] The usage process of the waste acid recovery and pretreatment device for ore testing provided by this utility model is as follows:

[0040] When a recycling bin 5 inside a separation bin 2 needs to be cleaned, the worker can hold the end of the adjusting screw 19 and rotate it. The rotation of the adjusting screw 19 will then drive the connecting plate 15 to move, which in turn will drive the transverse plate 14 to move.

[0041] When the transverse plate 14 and the connecting plate 15 move, they will drive the locking block 16 to move, thereby canceling the fixation of the recycling bin 5 that needs to be cleaned and locking the recycling bin 5 that was not previously used. Then the recycling bin 5 that needs to be cleaned can be pulled out from the top.

[0042] Furthermore, the movement of the transverse plate 14, in conjunction with the tooth groove 23, drives the rotation of the transmission gear 22. The rotation of the transmission gear 22 drives the rotation of the driven gear 20, which in turn drives the rotation of the rotating tube 11. Ultimately, this enables the rotating tube 11 to rotate from the top of the recycling bin 5 that needs to be cleaned to the top of another recycling bin 5, thereby achieving continuity of the pre-treatment work.
