Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic dosing device for electroplating wastewater treatment. Background Technology

[0002] Wastewater treatment is an important technology that benefits people's livelihoods and the environment. In addition to sewage generated in daily life, industrial production also produces a lot of wastewater, such as wastewater generated in electroplating technology. This wastewater contains harmful substances such as metals, organic matter, acids and alkalis, so it needs to be treated. In the treatment process, relevant elements and chemicals are added, and the elements are filtered, reacted and precipitated through physical and chemical treatment methods.

[0003] In existing technologies, electroplating wastewater treatment is generally divided into seven independent treatment processes, with dosing pumps added to each of the seven processes. This requires a large number of dosing pumps and supporting equipment, which not only increases costs but also increases the difficulty of controlling each dosing pump separately.

[0004] Therefore, how to provide an automatic dosing device for electroplating wastewater treatment is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an automatic dosing device for electroplating wastewater treatment. This invention solves the problem that setting up dosing pumps and supporting equipment for each process in the prior art increases costs and makes control more difficult.

[0006] An automatic dosing device for electroplating wastewater treatment according to an embodiment of the present invention includes a treatment tank and a dosing tank. A dosing pump is installed on the top of the dosing tank. A feed pipe is installed on the inlet of the dosing pump. The other end of the feed pipe is fixed to and communicates with the dosing tank. A discharge assembly is installed on the outlet of the dosing pump. The discharge assembly includes a main pipe, an extension pipe, and a distribution pipe. The main pipe is installed on the outlet of the dosing pump. The extension pipe is fixed to the other end of the main pipe. A bottom plate is installed at the bottom of the extension pipe. The bottom end of the bottom plate is fixed to the top of the treatment tank. The distribution pipe is fixed to the lower surface of the extension pipe. The other end of the distribution pipe extends to the bottom of the inner wall of the treatment tank. A pneumatic valve is installed on the distribution pipe.

[0007] The number and location of the distribution pipes and pneumatic valves are matched with the number and location of the treatment tanks.

[0008] The top of the dosing box is equipped with two sets of dosing components. One set of dosing components is for powder dosing, and the other set is for liquid dosing. Each dosing component includes a dosing box and a control valve. The bottom of the dosing box is connected to the dosing box through the control valve.

[0009] A diffusion assembly is provided on the distributing pipe. The diffusion assembly includes a drive motor, a transmission shaft, a rotating shaft, and fan blades. The drive motor is fixed on the distributing pipe near the extension pipe. A power gear is fixed on the output shaft of the drive motor. The transmission shaft is rotatably connected to the side of the distributing pipe. Both ends of the transmission shaft are fitted with transmission gears. The transmission gear at one end of the transmission shaft meshes with the power gear. A fixing rod is provided at the lower opening of the distributing pipe. The rotating shaft is rotatably connected to the fixing rod through a bearing. A movable gear is fixedly fitted on the surface of the rotating shaft. The movable gear meshes with another transmission gear on the transmission shaft. The fan blades are fixed on the rotating shaft and located below the movable gear.

[0010] The dosing tank is equipped with a stirring shaft inside, and a stirring motor is installed on the top of the dosing tank. The stirring motor is located at the top of the stirring shaft.

[0011] The treatment tank is also equipped with a pH monitor and an ORP electrode.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a discharge assembly, the discharge port is divided into a number that matches the number of treatment tanks. A dosing pump draws the chemicals into the discharge assembly, and the dosing into the treatment tanks is controlled by the pneumatic valves on the discharge assembly. This eliminates the need to set up a dosing pump in each treatment tank, achieving the effect of controlling the dosing of chemicals in multiple treatment tanks with one dosing pump and multiple sets of pneumatic valves. This solves the problem that setting up a dosing pump and supporting equipment for each process in the existing technology increases costs and control difficulty.

[0014] By setting up a diffusion component, the fan blades rotate when the diffusion component is activated, dispersing the reagents entering the treatment tank and mixing them with the wastewater in the treatment tank. This accelerates the diffusion of the reagents and improves the mixing efficiency between the reagents and the wastewater in the treatment tank. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Example 1

[0022] refer to Figure 1 and Figure 3 The system includes a treatment tank 1 and a dosing tank 2. The dosing tank 2 is equipped with a stirring shaft 23 inside and a stirring motor 24 on the top of the dosing tank 2. The stirring motor 24 is located on the top of the stirring shaft 23. The treatment tank 1 is also equipped with a pH monitor 25 and an ORP electrode 26. The pH monitor 25 is used to monitor the pH value in the treatment tank 1, and the ORP electrode 26 is used to measure the redox capacity in the solution. The degree of redox reaction is reflected by measuring the potential difference between the oxidant and the reductant in the solution. The pH value and ORP measurement data are transmitted to an external computer (not shown in the figure) for evaluation.

[0023] refer to Figure 1 and Figure 2A dosing pump 3 is installed on the top of the dosing tank 2. This pump 3 draws the liquid medicine inside the dosing tank 2 into the discharge assembly 5. A feed pipe 4 is installed at the inlet of the pump 3. When the pump 3 is operating, the liquid medicine inside the dosing tank 2 is drawn into the pump 3 through the feed pipe 4, and then reaches the discharge assembly 5. It should be noted that the end of the feed pipe 4 furthest from the pump 3 is located on the side of the dosing tank 2 closest to the bottom. This ensures that the liquid medicine inside the dosing tank 2 is completely drained. The other end of the feed pipe 4 is connected to the dosing... The housing 2 is fixed and connected. A discharge assembly 5 is installed at the output port of the dosing pump 3. The discharge assembly 5 includes a main pipe 6, an extension pipe 7, and a distribution pipe 8. The main pipe 6 is located at the output port of the dosing pump 3, and the liquid medicine enters the main pipe 6 under the action of the dosing pump 3. The extension pipe 7 is fixed to the other end of the main pipe 6, and a ramp 9 is installed at the bottom of the extension pipe 7. The liquid medicine reaches the extension pipe 7 through the main pipe 6. The bottom end of the ramp 9 is fixed to the top of the treatment tank 1, and the extension pipe 7 is stably fixed to the treatment tank 1 by the ramp 9. The distribution pipe 8 is fixed to the lower surface of the extension pipe 7. The other end extends to the bottom of the inner wall of the treatment tank 1. A pneumatic valve 10 is installed on the distribution pipe 8. The number and position of the distribution pipe 8 and the pneumatic valve 10 match the number and position of the treatment tanks 1. In this embodiment, there are seven sets of treatment tanks 1. Each set of treatment tanks 1 corresponds to one distribution pipe 8 and one pneumatic valve 10. The dosing pump 3 and the pneumatic valve 10 are also connected to an external computer. When it is necessary to add medicine to a certain set of treatment tanks 1, the pneumatic valve 10 at that position is opened through the external computer. Then, under the action of the dosing pump 3, the medicine is pushed through the distribution pipe 8 and the pneumatic valve 10 at that position. The actuated valve 10 reaches the treatment tank 1. It should be noted that not only can a single treatment tank 1 be added, but multiple treatment tanks 1 can also be added. This design not only reduces the number of dosing pumps 3 and supporting equipment, but also requires only one dosing pump 3 to transport the medicine. The medicine is added to the corresponding treatment tank 1 by controlling the dosing through the pneumatic valve 10. This not only reduces the cost of setting up equipment, but also reduces the difficulty of controlling the equipment. It should be noted that the liquid delivery is controlled by the electrically controlled valve 10 and the dosing pump 3 based on the evaluation data of the external computer.

[0024] Example 2

[0025] refer to Figure 2 The top of the dosing box 2 is provided with two sets of dosing components 11. One set of dosing components 11 is a powder dosing component 11, and the other set of dosing components 11 is a liquid dosing component 11. This is mainly used to separate dry and wet materials. The dosing component 11 includes a dosing box 12 and a control valve 13. The bottom of the dosing box 12 is connected to the dosing box 2 through the control valve 13.

[0026] Example 3

[0027] refer to Figure 2 and Figure 4 A diffusion assembly 14 is provided on the dispensing pipe 8. When the liquid medicine comes out of the dispensing pipe 8, the diffusion assembly 14 quickly diffuses the liquid medicine into the treatment tank 1. The diffusion assembly 14 includes a drive motor 15, a transmission shaft 16, a rotating shaft 17, and a fan blade 18. The drive motor 15 is fixed on the dispensing pipe 8 near the extension pipe 7. A power gear 19 is fixed on the output shaft of the drive motor 15. The transmission shaft 16 is rotatably connected to the side of the dispensing pipe 8. Both ends of the transmission shaft 16 are fitted with transmission gears 20. The transmission gear 20 at one end of the transmission shaft 16 meshes with the power gear 19. A fixing rod 21 is provided at the lower opening of the dispensing pipe 8. The rotating shaft 17 is rotatably connected to the fixing rod 21 through a bearing. A movable gear 22 is fixedly sleeved on the surface of the rotating shaft 17. The movable gear 22 meshes with another transmission gear 20 on the transmission shaft 16. The fan blade 18 is fixed on the rotating shaft 17 and located below the movable gear 22. During operation, the drive motor 15 starts and drives the power gear 19 to rotate. The rotation of the power gear 19 drives the transmission shaft 16 to rotate through the transmission gear 20. The rotation of the transmission shaft 16 drives the movable gear 22 to rotate through the other transmission gear 20. The movable gear 22 drives the rotating shaft 17 to rotate through the bearing. In this way, the rotation of the rotating shaft 17 drives the fan blade 18 to rotate quickly to disperse and quickly mix the liquid medicine that has reached this position in the treatment tank 1, thus achieving the effect of quickly dispersing and quickly mixing the liquid medicine in the treatment tank 1.
