Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a metal recovery device for industrial wastewater treatment. Background Technology

[0002] The need to recover metals from industrial wastewater stems from two main reasons: first, these heavy metals are highly toxic and pose a serious threat to the environment and human health; second, recovery allows for resource reuse, aligning with the principles of a circular economy. Common recovery methods include biosorption, chemical precipitation, electrolysis, and ion exchange. Chemical precipitation involves adding appropriate chemical reagents (such as lime or sodium sulfide) to a sedimentation tank, causing dissolved metal ions in the wastewater to form insoluble precipitates, thus achieving metal separation and recovery. This method has a relatively simple operation process and can typically complete the removal or conversion of metal ions in a short time, making it suitable for treating large volumes of wastewater and therefore widely used.

[0003] Existing methods for adding chemical reagents to sedimentation tanks generally have significant drawbacks: traditional methods often involve fixed-point feeding (such as a single feeding port or manual dumping), making it difficult for chemical reagents to evenly cover the entire sedimentation tank area. This can easily lead to excessively high concentrations in some areas (such as clumping) while the concentrations in other areas are insufficient, resulting in inadequate precipitation of metal ions and affecting the recovery effect. Therefore, we propose a metal recovery device for industrial wastewater treatment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a metal recovery device for industrial wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metal recovery device for industrial wastewater treatment includes a sedimentation tank body. Two U-shaped guide rails are fixedly connected to the top of the sedimentation tank body. A reagent dispensing chamber is located at the top of the sedimentation tank body. Four T-shaped bushings are fixedly connected to the bottom of the reagent dispensing chamber. The inner walls of two T-shaped bushings are rotatably connected to the same drive shaft. An L-shaped frame is fixedly connected to the outer wall of the reagent dispensing chamber. A servo motor is fixedly connected to the outer wall of the L-shaped frame. One end of the output shaft of the servo motor is fixedly connected to one end of one of the drive shafts. Two wheels are fixedly fitted onto the outer walls of both ends of the two drive shafts. Multiple strip-shaped dispersing plates are fixedly connected to the outer wall of one of the drive shafts. A dispensing assembly is located inside the reagent dispensing chamber.

[0007] Preferably, the dispensing component includes a driven shaft, one end of which is fixedly connected to a main gear, and one end of which is fixedly connected to a driven gear. The main gear and the driven gear are meshed together. One end of the driven shaft is fixedly connected to a feeding roller. The outer wall of the feeding roller is evenly provided with a plurality of feeding recesses. By setting the dispensing component, it is convenient to evenly dispense the agent into the sedimentation tank.

[0008] Preferably, two baffles are fixedly connected to the top of the sedimentation tank body to prevent the reagent dosing chamber from moving out of the two guide rails.

[0009] Preferably, the wheel is located inside the U-shaped guide rail, and two U-shaped guide rails are provided to assist the wheel in linear movement.

[0010] Preferably, the outer wall of the drug delivery chamber has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the driven shaft.

[0011] Preferably, a bearing is fixedly sleeved on the outer wall of the driven shaft, and the outer ring of the bearing is fixedly connected to the inner wall of the drug delivery chamber. The bearing assists the driven shaft to rotate stably.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses a servo motor to drive the transmission shaft and move the wheels along the U-shaped guide rail, allowing the chemical reagent dispensing chamber to move back and forth on the top of the sedimentation tank. This breaks the limitation of fixed-point dispensing and ensures that the chemical reagents can cover the entire sedimentation tank.

[0014] The rotation of the drive shaft synchronously drives the main gear, driven gear, and driven shaft to rotate, causing the chemical reagent to be released into the discharge concave hole of the discharge roller. Combined with the strip-shaped dispersing plate on the drive shaft, the falling chemical reagent is dispersed, preventing the chemical reagent from clumping and greatly improving the mixing uniformity of the chemical reagent and wastewater.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a metal recovery device for industrial wastewater treatment is disclosed, including a sedimentation tank body 1. Two U-shaped guide rails 2 are fixedly connected to the top of the sedimentation tank body 1. The two U-shaped guide rails 2 provide a stable movement trajectory for the wheels 10, restrict the movement direction of the reagent dosing chamber 4, and ensure that it can move back and forth smoothly along the top of the sedimentation tank body 1, avoiding deviation or shaking during the dosing process. Two baffles 3 are fixedly connected to the top of the sedimentation tank body 1.

[0023] The top of the sedimentation tank body 1 is equipped with a reagent dosing chamber 4, which is used to store reagents such as lime and sodium sulfide, providing a centralized space for reagent dosing. The bottom of the reagent dosing chamber 4 is fixedly connected with four T-shaped bushings 5. The inner walls of two T-shaped bushings 5 ​​are rotatably connected to the same drive shaft 8. The four T-shaped bushings 5 ​​are paired up to provide stable support for the two drive shafts 8, reducing the radial sway of the drive shafts 8 during rotation.

[0024] An L-shaped frame 6 is fixedly connected to the outer wall of the drug dispensing chamber 4. A servo motor 7 is fixedly connected to the outer wall of the L-shaped frame 6. The servo motor 7 is powered by the built-in battery of the drug dispensing chamber 4. An existing encoder is installed on the outer wall of the output shaft of the servo motor 7. One end of the output shaft of the servo motor 7 is fixedly connected to one end of one of the drive shafts 8. The power of the servo motor 7 is transmitted to two wheels 10 connected to it through the drive shaft 8, which drives the other two wheels 10 to move with the drug dispensing chamber 4. Two wheels 10 are fixedly fitted on the outer walls of both ends of the two drive shafts 8. The wheels 10 are located inside the U-shaped guide rail 2.

[0025] Multiple strip-shaped dispersing plates 9 are fixedly connected to the outer wall of one of the drive shafts 8. They rotate under the drive of the drive shaft 8, which can fully disperse and disperse the medicine falling from the medicine dispensing chamber 4, and prevent the medicine from clumping.

[0026] The medicine dispensing chamber 4 is equipped with a dispensing assembly, which includes a driven shaft 13. The outer wall of the medicine dispensing chamber 4 has a through hole, and the inner wall of the through hole is rotatably connected to the outer wall of the driven shaft 13. A bearing is fixedly sleeved on the outer wall of the driven shaft 13, and the outer ring of the bearing is fixedly connected to the inner wall of the medicine dispensing chamber 4. One end of a drive shaft 8 is fixedly connected to a main gear 11, and one end of the driven shaft 13 is fixedly connected to a driven gear 12. The main gear 11 and the driven gear 12 are meshed. One end of the driven shaft 13 is fixedly connected to a feeding roller 14, and one end of the feeding roller 14 is fixedly sleeved with a ball bearing. The outer ring of the ball bearing is fixedly connected to the inner wall of the medicine dispensing chamber 4. The outer wall of the feeding roller 14 is evenly provided with multiple feeding recesses 15.

[0027] The main gear 11 rotates with the drive shaft 8 and transmits power to the driven shaft 13 through meshing with the driven gear 12, realizing the linkage between the drive shaft 8 and the driven shaft 13, and ensuring that the rotation of the feed roller 14 is coordinated with the movement of the drug delivery chamber 4 and the rotation of the strip dispersion 9.

[0028] Working Principle: In the metal recovery and collection of industrial wastewater, the wastewater undergoes sedimentation in the sedimentation tank 1. Before sedimentation, the required chemical reagents (such as lime, sodium sulfide, etc.) are placed inside the chemical reagent inlet 4. The servo motor 7 drives the connected drive shaft 8 to rotate, which in turn drives the two wheels 10 to rotate. The two wheels 10 then move the chemical reagent inlet 4. As the chemical reagent inlet 4 moves, the drive shaft 8 drives the connected main gear 11 to rotate, which in turn drives the driven gear 12 to rotate. The driven gear 12 then drives the driven shaft 13 to rotate. The rotation of shaft 13 drives the connected feeding roller 14 to rotate, which in turn drives the upper and lower sets of feeding recesses 15 to rotate. The rotation of the upper and lower sets of feeding recesses 15 feeds the chemical reagents (such as lime, sodium sulfide, etc.) in the chemical reagent feeding chamber 4 downwards. The rotation of the drive shaft 8 drives the multiple strip-shaped dispersing plates 9 connected to it to rotate. The rotation of the multiple strip-shaped dispersing plates 9 disperses the falling chemical reagents, making it easier to evenly feed them into the interior of the sedimentation tank body 1. The chemical reagents are fed in as the chemical reagent feeding chamber 4 moves. As the servo motor 7 reciprocates at the top of the sedimentation tank body 1, the chemical reagents are fed back and forth evenly.

[0029] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the servo motor 7 and the battery to facilitate the control of the overall operation.
