Description

Technical Field

[0001] This utility model relates to the field of electroplating wastewater treatment technology, specifically to a treatment device for electroplating wastewater. Background Technology

[0002] Electroplating wastewater generally originates from: cleaning water for plated parts, waste electroplating solutions, and other wastewater, including water used for rinsing workshop floors, washing plates, condensate from ventilation equipment, and various tank solutions and drainage caused by leakage or improper operation and management, as well as equipment cooling water. Cooling water is not contaminated during use except for temperature increases. The quality and quantity of electroplating wastewater are related to factors such as the electroplating production process conditions, production load, operation and management, and water usage. Electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, and silver, as well as cyanides, some of which are highly toxic substances that are carcinogenic, teratogenic, and mutagenic.

[0003] For example, patent document CN 222159807 U discloses an electroplating wastewater recycling and treatment device, which relates to the field of electroplating wastewater treatment technology. The device includes a tank, a conversion box fixedly installed at the top of the tank, a water collection chamber inside the tank, a drain outlet at the top of the water collection chamber, an inner cylinder fixedly installed at the center of the water collection chamber, a liquid storage chamber inside the inner cylinder, several heating tubes fixedly installed on the inner wall of the liquid storage chamber, an activated carbon filter plate fixedly installed at the top of the liquid storage chamber, a gas collecting hopper fixedly installed at the top of the inner cylinder, and a condenser fixedly installed inside the conversion box. The electroplating wastewater stored in the liquid storage chamber is heated and evaporated by the heating tubes inside the inner cylinder. The rising water vapor passes through the activated carbon filter plate to filter harmful particles. The water vapor is then fed into the condenser through the gas collecting hopper, condensed into water by several condensing tubes, discharged from the vent, and dripped into the water collection chamber for storage and collection. This fully recycles and reuses the water vapor, avoiding resource waste and environmental pollution.

[0004] However, in practice, due to its structural limitations, this structure often only allows for unidirectional flow of electroplating wastewater through filtration. During the process, it is impossible to quickly replace the filter cartridge, and the equipment cannot perform more efficient electroplating wastewater purification. Therefore, it cannot meet the needs of daily use. Thus, there is an urgent need to design an electroplating wastewater treatment device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a treatment device for electroplating wastewater, so as to solve the problem mentioned in the background art. In actual operation, due to the limitations of its own structure, the existing structure can only perform unidirectional flow electroplating wastewater filtration treatment. During the treatment process, it is not possible to quickly replace the filter element. At the same time, the equipment cannot perform more efficient electroplating wastewater purification treatment, which cannot meet the problems in daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a treatment device for electroplating wastewater, comprising a connecting seat, wherein a liquid equalization tube cover is fixedly connected to both ends of the connecting seat, a sleeve ring seat is fixedly connected to one end of the liquid equalization tube cover, a liquid delivery side seat is fixedly connected to the bottom end of the sleeve ring seat, and a liquid control pump is provided at the bottom end of the liquid delivery side seat.

[0007] An infusion stand is fixedly connected between the two sets of control pumps. A pull-out base is movably connected to the bottom of the infusion stand, and an outlet valve seat is provided on the front of the infusion stand.

[0008] Preferably, a filter frame is fixedly connected to the top of the pull-out base, and a liquid outlet valve is provided on the front of the filter frame.

[0009] Preferably, the filter frame is provided with an activated carbon core inside, and a sealing strip is provided between the pull-out base and the liquid outlet valve seat.

[0010] Preferably, the bottom of the liquid control pump is fixedly connected to a support base.

[0011] Preferably, the sleeve seat is internally movably connected to a pull-out side seat, and a sealing side ring is provided on the side of the pull-out side seat.

[0012] Preferably, a filter element is fixedly connected to one end of the pull-out side seat, and a docking seat is fixedly connected to one end of the filter element.

[0013] Preferably, the inner wall of the liquid distribution tube cover is provided with an annular liquid distribution grid, and the top of the connecting seat is provided with a liquid inlet valve seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This electroplating wastewater treatment device, through its connecting seat, uniform liquid pipe cover, sleeve ring seat, liquid delivery side seat, liquid control pump, pumping side seat, sealing side ring, filter element, docking seat, annular uniform liquid grid, and inlet valve seat, enables more efficient two-way flow treatment of electroplating wastewater. In actual use, the operator first introduces the electroplating wastewater through the inlet valve seat at the top of the connecting seat, and then alternately starts the liquid control pumps at the bottom of the liquid delivery side seats at both ends. This allows the electroplating wastewater entering through the connecting seat to flow into the uniform liquid pipes at both ends. The electroplating wastewater flows through the shroud and is evenly distributed in a ring-shaped manner via the annular grid on the inner wall of the shroud. This distributed wastewater is then filtered by the filter element at one end of the pull-out side seat. The filtered wastewater is discharged through the delivery side seat. The pull-out side seat can be quickly adjusted for sealing via the side sealing ring and the docking seat at one end of the filter element, thus enabling the switching and diversion of the electroplating wastewater at both ends and facilitating efficient replacement and maintenance of the filter element. This demonstrates the practicality of the equipment design.

[0016] This electroplating wastewater treatment device, through its integrated components including a controlled-liquid pump, a liquid delivery rack, a pull-out base, an outlet valve seat, a filter rack, an outlet valve port, an activated carbon core, sealing strips, and a support base, further enhances the overall performance of the equipment. During daily use, after the electroplating wastewater passes through the filter core, the filtered wastewater is then pumped into the liquid delivery rack via the controlled-liquid pumps at both ends, entering from the top of the filter rack. The activated carbon core inside the filter rack further adsorbs and treats the wastewater. Finally, the treated wastewater is discharged from the outlet valve port on the filter rack, flowing through the outlet valve seat on the front of the liquid delivery rack. Simultaneously, the pull-out base at the bottom of the liquid delivery rack allows for quick removal of the filter rack and rapid replacement of the activated carbon core. The liquid delivery rack and pull-out base are sealed together with sealing strips, demonstrating the comprehensive design of the equipment. Attached Figure Description

[0024] Please see Figure 1-5 One embodiment provided by this utility model:

[0025] A treatment device for electroplating wastewater includes a connecting base 1, with a liquid distribution tube cover 2 fixedly connected to both ends of the connecting base 1. A sleeve ring seat 3 is fixedly connected to one end of the liquid distribution tube cover 2. A liquid delivery side seat 4 is fixedly connected to the bottom end of the sleeve ring seat 3. A liquid control pump 5 is installed at the bottom end of the liquid delivery side seat 4. A pull-out side seat 14 is movably connected inside the sleeve ring seat 3. A sealing side ring 15 is provided on the side of the pull-out side seat 14. A filter element 16 is fixedly connected to one end of the pull-out side seat 14. One end of 16 is fixedly connected to a docking seat 17. The inner wall of the liquid equalization tube cover 2 is provided with an annular liquid equalization grid 18. The top of the connecting seat 1 is provided with an inlet valve seat 19, so that the electroplating wastewater entering at the connecting seat 1 flows to the two ends of the liquid equalization tube cover 2. Through the annular liquid equalization grid 18 on the inner wall of the liquid equalization tube cover 2, the electroplating wastewater can be evenly divided in an annular manner. The annularly divided electroplating wastewater is then filtered in conjunction with the filter element 16 at one end of the pull-out side seat 14.

[0026] An infusion rack 6 is fixedly connected between two sets of liquid control pumps 5. A pull-out base 7 is movably connected to the bottom of the infusion rack 6. An outlet valve seat 8 is provided on the front of the infusion rack 6. A filter rack 9 is fixedly connected to the top of the pull-out base 7. An outlet valve port 10 is provided on the front of the filter rack 9. An activated carbon core 11 is provided inside the filter rack 9. A sealing strip 12 is provided between the pull-out base 7 and the outlet valve seat 8. A support base 13 is fixedly connected to the bottom of the liquid control pump 5. The filtered wastewater is then introduced into the interior of the infusion rack 6 through the two end liquid control pumps 5 and enters from the top of the filter rack 9. The activated carbon core 11 inside the filter rack 9 can achieve further adsorption treatment of the electroplating wastewater.

[0027] Working Principle: During use, the operator first introduces electroplating wastewater through the inlet valve seat 19 at the top of the connector 1. Then, the operator alternately starts the control pumps 5 at the bottom of the two end supply side seats 4, causing the electroplating wastewater entering through the connector 1 to flow to the two end uniform distribution pipe covers 2. Through the annular uniform distribution grid 18 on the inner wall of the uniform distribution pipe cover 2, the electroplating wastewater is evenly distributed in an annular manner. The annularly distributed electroplating wastewater is then filtered by the filter element 16 at one end of the pull-out side seat 14. The filtered electroplating wastewater is discharged along the supply side seat 4. Simultaneously, the pull-out side seat 14 can be quickly adjusted through the side sealing ring 15 and the docking seat 17 at one end of the filter element 16, thereby achieving the switching and diversion of the electroplating wastewater at both ends for filtration. The efficient replacement and maintenance of filter core 16 is achieved as follows: During daily use, after electroplating wastewater is filtered by filter core 16, the filtered wastewater is then introduced into the liquid delivery rack 6 through the two-end liquid control pumps 5 and enters from the top of the filter rack 9. The activated carbon core 11 inside the filter rack 9 can further adsorb and treat the electroplating wastewater. Finally, the treated wastewater can be discharged from the outlet valve 10 of the filter rack 9 along the outlet valve seat 8 on the front of the liquid delivery rack 6. At the same time, the pull-out base 7 at the bottom of the liquid delivery rack 6 can carry the filter rack 9 for quick removal and quick replacement of the activated carbon core 11. The liquid delivery rack 6 and the pull-out base 7 are sealed by a sealing strip 12. The above is the complete working principle of this utility model.
