Description

Technical Field

[0001] This invention relates to the field of electroplating wastewater treatment technology, specifically to an electroplating wastewater treatment device and method. Background Technology

[0002] Wastewater and waste liquid discharged from electroplating plants contain a large number of metal ions such as chromium, cadmium, and nickel, as well as cyanide, acids, and alkalis, and often contain organic additives. Some metal ions exist as simple cations, some as anions, and some as complex complex ions. Common chemical methods for treating electroplating wastewater include neutralization precipitation, neutralization coagulation precipitation, oxidation, reduction, barium salt methods, and ferrite methods. To improve the treatment efficiency, activated carbon adsorption is typically used first to remove most of the organic matter and heavy metal ions from the wastewater, followed by chemical treatment to further remove or transform the remaining harmful substances. This comprehensive treatment process can achieve compliance with emission standards.

[0003] According to Chinese Patent No. CN114084978A, a novel integrated electroplating wastewater treatment device is disclosed. With the setting of this invention, impurities can be separated from electroplating wastewater after high stirring treatment, and the clean water and impurities can be effectively separated and collected, thereby improving the treatment effect of electroplating wastewater and effectively avoiding secondary pollution.

[0004] The above-mentioned technical solution uses activated carbon adsorption treatment and adds chemical solution to fully mix with wastewater during the reaction, and uses a stirring mechanism to mix the reaction. This operation involves continuously using the same packing material for adsorption, and the packing material cannot maintain a high adsorption efficiency for a long time. In addition, the chemical solution is added in a single spray during the chemical reaction, which makes the chemical reaction of electroplating wastewater take a long time. Therefore, we propose an electroplating wastewater treatment device and method. Summary of the Invention

[0009] Preferably, an inlet is connected to one side of the primary filter tank, an outlet is connected to one side of the bottom tank, and a screen for removing impurities from the wastewater is installed in the middle of the primary filter tank.

[0010] Preferably, the pump body is mounted on the middle of the conduit via a flange.

[0011] Preferably, an activation mechanism is provided on the upper side of the insertion tube near the through hole. The activation mechanism includes a mounting base that is mated to the upper side of the insertion tube. The top of the mounting base is an arc surface. A groove is formed in the middle of the arc surface of the mounting base, and a slot is formed in the middle of the groove. The two sides of the mounting base are provided with mating channels that communicate with the groove.

[0012] Preferably, a spring is connected to the inner wall of the groove of the mounting base, and an extrusion member is slidably connected to the side of the groove near the docking channel. The surface of the extrusion member is provided with a U-shaped inner cavity, and the inner wall of one side of the U-shaped inner cavity is provided with equidistantly distributed protrusions.

[0013] An equally spaced arc-shaped blowpipe is provided between the spring and the extruder, and equally spaced air inlets are provided on the outer arc surface of the arc-shaped blowpipe.

[0014] Preferably, the bottom of the arc-shaped blowpipe is fixed with a horizontal pipe that mates with the slot, and the lower side of the middle of the horizontal pipe is connected to a corrugated pipe. A positioning pin is connected to the outer peripheral side wall of the rotating drum near the conical bucket, and a ball is movably connected to one end of the positioning pin.

[0015] Preferably, an air inlet pipe is connected to the lower side of the mounting base. The air inlet pipe is connected to the bottom end of the bellows. The air inlet pipe is movably connected to the rotating drum through a sealed bearing. One end of the air inlet pipe extends through the upper housing.

[0016] Preferably, a medicine tank is provided on the side of the bottom box away from the rotary joint.

[0017] A method for treating electroplating wastewater includes the following steps:

[0018] S1. The electroplating wastewater is initially filtered and impurities are removed through the primary filter tank;

[0019] S2. Electroplating wastewater is continuously adsorbed and treated by the continuously rotating adsorption packing in the upper chamber.

[0020] S3. The wastewater after adsorption treatment undergoes a full chemical reaction with the chemical agents sprayed from the spray pipe and the dosing reaction mechanism.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The electroplating wastewater treatment device and method are configured with a chemical dosing reaction mechanism linked to an adsorption component. The industrial electroplating wastewater is filtered through a primary filter and then fed into a rotating drum. As the drum rotates, it drives multiple adsorption fillers to alternately adsorb and remove most of the organic matter and heavy metal ions in the wastewater. The chemical agent sprayed through the spray pipe mixes with the electroplating wastewater through vibration. The spray nozzle of the chemical dosing reaction mechanism rotates and swings, causing the spray nozzle to swing and spray the chemical agent to mix and contact with the electroplating solution. This allows the electroplating wastewater to react stepwise with the chemical agent in the bottom tank, ensuring that the electroplating wastewater treatment device can effectively treat the harmful substances in the electroplating wastewater.

[0023] 2. The electroplating wastewater treatment device and method are configured with an adsorption component and an activation mechanism linked together. When the adsorption packing of the adsorption component rotates and adjusts its position with the rotating drum, the positioning pin intermittently drives the extrusion piece and the arc-shaped blowing pipe to slide back and forth along the groove. When the arc-shaped blowing pipe moves back and forth, it blows air through the air port on the outer arc surface to heat the adsorption packing that rotates past the mounting seat. This ensures that the adsorption packing can be activated and regenerated without stopping while rotating with the rotating drum, thus ensuring that the adsorption packing has sufficient efficiency in adsorbing and treating electroplating wastewater.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-10 This invention provides a technical solution: an electroplating wastewater treatment device, comprising an upper chamber 1, a primary filter 2, and a dosing reaction mechanism 4. A partition 101 is fixed in the middle of the upper chamber 1. The primary filter 2 is arranged on one side of the upper chamber 1, and a conduit 202 is connected to one side of the primary filter 2. A pump body 203 is installed in the middle of the conduit 202 via a flange. A bottom chamber 3 is installed below the upper chamber 1. An adsorption assembly 5 is arranged inside the upper chamber 1, and the dosing reaction mechanism 4 is arranged inside the bottom chamber 3. The adsorption assembly 5 includes a cone 502 rotatably connected to one side of the upper box 1. The middle of the cone 502 is rotatably connected to an insertion tube 501 via a sealed bearing. One end of the insertion tube 501 is fixed to the conduit 202. A rotating cylinder 506 is movably connected to one side of the partition 101. Adsorption filler 507 is installed at equal angles on the circumferential side of the rotating cylinder 506. The adsorption filler 507 is made of activated carbon material. Two spray pipes 8 located below the rotating cylinder 506 are also inserted into the middle of the upper box 1.

[0039] Two flow guide plates 401 are symmetrically installed on the upper inner wall of the bottom tank 3. An elastic strip 402 is connected to the bottom end of each flow guide plate 401. The flow guide plates 401 are inclined, and the elastic strip 402 is made of an elastic material not limited to rubber. A separation tank 404 for filtering sedimentation is fixed to the bottom of adjacent sides of the two flow guide plates 401. A spray pipe 403 is installed in the middle of the separation tank 404. Spray nozzles are equidistantly arranged on the outer periphery of the spray pipe 403. One end of the spray pipe 403 is offset. The bottom box 3 is connected by a connecting pipe 405. The end of the connecting pipe 405 that extends through the bottom box 3 is connected to a rotary joint 406. The opening on the upper side of the bottom box 3 is provided with inclined plates 301 at equal intervals. The outer wall of the cone 502 is provided with a toothed ring 503. The inner wall of the upper box 1 is provided with a transmission gear 408 that meshes with the toothed ring 503. Synchronous pulleys are sleeved on the outer side of the connecting pipe 405 and the end of the central shaft of the transmission gear 408. A synchronous belt 407 is sleeved between the two synchronous pulleys.

[0040] A medicine tank 9 is provided on the side of the bottom tank 3 away from the rotary joint 406. The medicine tank 9 is connected to the spray pipe 8 and the rotary joint 406 respectively through an internal metering pump. The side of the upper tank 1 near the medicine tank 9 is connected to a discharge pipe 10 for cleaning the sediment inside the separation tank 404. A control valve for controlling the opening and closing is connected to the discharge pipe 10. By adding cleaning solution to the primary filter tank 2 and opening the control valve on the discharge pipe 10, the cleaning solution is driven by the pump body 203 to be sent into the rotating drum 506. Then the cleaning solution enters the bottom tank 3 and carries the sediment impurities in the separation tank 404 out along the discharge pipe 10, which facilitates the cleaning of sediment impurities generated by electroplating wastewater treatment.

[0041] A motor 505 is installed on the outer side of the upper housing 1. The output end of the motor 505 is inserted through the upper housing 1 and connected to a drive gear 504. The drive gear 504 meshes with a gear ring 503. A through hole is opened on the lower side of the end of the insertion tube 501 that extends into the rotating drum 506. By opening a through hole on the surface of the insertion tube 501, wastewater can easily enter the insertion tube 501 along the conduit 202. Then, the wastewater enters the rotating drum 506 through the through hole of the insertion tube 501, so that the wastewater can be directly sent into the rotating drum 506 for adsorption treatment.

[0042] The primary filter tank 2 has an inlet connected to one side, and the bottom tank 3 has an outlet connected to one side. A screen 201 for removing impurities from the wastewater is installed in the middle of the primary filter tank 2.

[0043] In practice, electroplating wastewater from industrial production enters the primary filter tank 2 through the inlet. Impurities are filtered by the screen 201 in the primary filter tank 2. The filtered wastewater then enters the conduit 202, where a pump 203 drives it to flow along the insertion pipe 501 into the rotating drum 506. When the motor 505 drives the drive gear 504 to rotate forward, the drive gear 504 meshes with the toothed ring 503 on the outer side of the cone hopper 502, causing the cone hopper 502 to rotate. The drum 506 rotates in the opposite direction. When the drum 506 rotates in the opposite direction, it will drive the adsorption packing 507, which is distributed at equal angles, to rotate in the same direction. The rotating adsorption packing 507 will throw the wastewater in the drum 506 into the bottom box 3. The adsorption packing 507 will adsorb and remove most of the organic matter and heavy metal ions in the wastewater. By rotating the drum 506, the adsorption packing 507 can be alternately inserted into the wastewater for adsorption treatment, ensuring that the adsorption packing 507 can continuously and efficiently adsorb and treat the wastewater.

[0044] When the rotating adsorption packing 507 throws the wastewater from the rotating drum 506 into the bottom tank 3, the metering pump in the chemical tank 9 pressurizes and delivers the chemical into the spray pipe 8. Then, the chemical is sprayed obliquely into the bottom tank 3 through the spray pipe 8. When the chemical hits the inclined plate 301, the inclined plate 301 causes the chemical to backflow upwards, impacting the rotating drum 506. This causes the water thrown downwards by the adsorption packing 507 to vibrate and mix with the chemical, thereby accelerating the mixing efficiency. Furthermore, the wastewater and chemical... When the mixture is generated, it falls along the inclined plate 301 into the bottom box 3; simultaneously, the reverse-rotating gear ring 503 meshes with the transmission gear plate 408, causing the transmission gear plate 408 to drive the synchronous belt 407 to rotate forward via the synchronous pulley, and then the synchronous belt 407 drives the synchronous pulley on the connecting pipe 405 to rotate forward, thereby the connecting pipe 405 drives the eccentrically connected injection pipe 403 to rotate and swing forward between the two elastic strips 402, and when the medicine in the medicine tank 9 is sent into the injection pipe 403 through the rotary joint 406, the injection... When the nozzle 403 rotates and oscillates in the forward direction, it causes the nozzle to swing and spray the agent, allowing the agent to mix and contact with the mixture falling into the bottom tank 3 from bottom to top. At the same time, when the nozzle 403 rotates and oscillates eccentrically, it will have intermittent movements of squeezing contact and deflection separation with the elastic strip 402. When the nozzle 403 squeezes and contacts the elastic strip 402, the mixture will accumulate on the upper side of the guide plate 401 to carry out a chemical reaction. When the nozzle 403 deflects and separates from the elastic strip 402, the mixture will flow along the nozzle. The gap between 403 and the elastic strip 402 leads to the separation tank 404; then the rotating spray pipe 403 sprays the agent into the separation tank 404, so that the mixture reacts with the agent three times in the separation tank 404, so that the electroplating wastewater can fully react chemically in the bottom tank 3 to change the physical and chemical properties of the pollutants in the wastewater, so that the separation tank 404 filters the sediment of the pollutant transformation, and finally, the wastewater that has completed the reaction with the chemical agent is discharged out through the drain outlet on the side of the bottom tank 3.

[0045] Please see Figure 3 , Figures 9-12 An activation mechanism 6 is provided on the upper side of the insertion tube 501 near the through hole. The activation mechanism 6 includes a mounting base 601 that is connected to the upper side of the insertion tube 501. The top of the mounting base 601 is an arc surface. A groove is provided in the middle of the arc surface of the mounting base 601, and a slot 602 is provided in the middle of the groove. The two sides of the mounting base 601 are provided with docking channels 603 that communicate with the groove.

[0046] A spring 604 is connected to the inner wall of the groove of the mounting base 601, and an extrusion member 605 is slidably connected to the side of the groove near the docking channel 603. The surface of the extrusion member 605 has a U-shaped inner cavity, and the inner wall of one side of the U-shaped inner cavity has equidistantly distributed protrusions. An arc-shaped blowpipe 606 is provided between the spring 604 and the extrusion member 605, and an air blowing port is provided on the outer arc surface of the arc-shaped blowpipe 606.

[0047] The bottom of the arc-shaped jet pipe 606 is fixed with a horizontal pipe that docks with the slot 602, and the lower side of the middle of the horizontal pipe is connected to a corrugated pipe 607. When the arc-shaped jet pipe 606 moves back and forth, the corrugated pipe 607 is stretched back and forth, so that hot air can be continuously introduced into the interior of the arc-shaped jet pipe 606. A positioning pin 608 is connected to the outer peripheral side wall of the rotating cylinder 506 near the cone 502, and a ball is movably connected to one end of the positioning pin 608.

[0048] An air inlet pipe 609 is connected to the lower side of the mounting base 601. The air inlet pipe 609 is connected to the bottom end of the bellows 607. The air inlet pipe 609 is movably connected to the rotating drum 506 through a sealed bearing. One end of the air inlet pipe 609 extends through the upper housing 1. An electric heater 7 that is connected to the air inlet pipe 609 is installed on the outside of the upper housing 1. A blower fan is installed on the surface of the electric heater 7.

[0049] In practice, when the cone bucket 502 drives the rotating drum 506 to rotate on one side of the partition plate 101, the rotating drum 506 will drive the adsorption packing 507 to rotate and adjust its position. When the adsorption packing 507 rotates upward and approaches the mounting base 601, the positioning pin 608 installed on the rotating drum 506 will enter the U-shaped inner cavity of the extruder 605 along the docking channel 603 on the edge of the mounting base 601. As the positioning pin 608 continues to rotate with the rotating drum 506, the positioning pin 608 will intermittently press against the protrusion on the inner wall of the extruder 605 through the ball at one end. Thus, with the assistance of the spring 604, the extruder 605 and the arc-shaped blowpipe 606 can slide back and forth along the groove, and the arc-shaped blowpipe... The horizontal tube on the lower surface of tube 606 slides along the slot 602. When the electric heater 7 and the blower are started, the blower sends air to the electric heater 7 for heating, and the hot air is introduced into the equally spaced arc-shaped blow pipes 606 along the air inlet pipe 609 and the corrugated pipe 607. When the arc-shaped blow pipes 606 move back and forth, they blow air through the air outlet on the outer arc surface to heat the adsorption packing 507 that rotates through the mounting base 601. This allows the adsorption packing 507 to be activated and regenerated under heating, ensuring that the adsorption packing 507 can be activated and regenerated without stopping while rotating with the rotating drum 506. This ensures that the adsorption packing 507 has sufficient efficiency in adsorbing and treating electroplating wastewater.

[0050] A method for treating electroplating wastewater includes the following steps:

[0051] S1. The electroplating wastewater is initially filtered and impurities are removed through the primary filter tank 2, thereby removing large particulate impurities in the electroplating wastewater. The high efficiency of filtration and impurity removal can be ensured by regularly cleaning the screen 201 in the primary filter tank 2.

[0052] S2. Electroplating wastewater is continuously adsorbed by the continuously rotating adsorption packing 507 in the upper box 1. When the adsorption packing 507, which is distributed at equal angles, rotates with the rotating drum 506, the adsorption packing 507 can adsorb and treat the wastewater when it rotates to the lower side of the rotating drum 506, and the adsorption packing 507 can be activated and regenerated by the activation mechanism 6 when it rotates to the upper side of the rotating drum 506.

[0053] S3. The wastewater after adsorption treatment undergoes a full chemical reaction with the chemical agents sprayed from the spray pipe 8 and the dosing reaction mechanism 4, so that the mixed liquid in the chemical reaction process can precipitate impurities.

[0054] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
