Description

Technical Field

[0001] The invention belongs to the field of electroplating degreasing waste liquid treatment system, in particular to an intelligent electroplating degreasing waste liquid treatment system. Background Art

[0002] From the perspective of the electroplating production process, electroplating wastewater can be roughly divided into four categories: pre-treatment wastewater, plating rinsing wastewater, post-treatment wastewater, waste plating liquid, and waste stripping liquid. Pre-treatment wastewater is mainly wastewater generated by cleaning the workpiece oil, namely, electroplating degreasing waste liquid. The electroplating degreasing waste liquid contains some oil. If the oil is not treated and discharged directly, it will cause great pollution to the ecological environment.

[0003] In order to more conveniently treat electroplating degreasing waste liquid, Chinese patent document CN218403778U proposes a electroplating degreasing waste liquid treatment device, including a kettle body, a kettle cover is installed on the top of the kettle body by bolts, a motor is arranged on the kettle cover, a motor shaft is arranged on the motor, the motor shaft is rotatably connected to the kettle cover, a connecting sleeve is installed on the motor shaft by bolts, a rotating shaft is fixedly connected to the connecting sleeve, and two symmetrically distributed mounting shells are fixedly connected to the rotating shaft. The diatomite plate and the zeolite plate can be driven to rotate by the motor, so that the oil and heavy metals in the waste liquid can be quickly absorbed, and a water tank is arranged on the outside of the kettle body, and a heating rod is arranged in the water tank, so that the waste liquid in the kettle body can be indirectly heated, thereby increasing the rate at which the oil and heavy metals in the waste liquid are absorbed and accelerating the treatment efficiency.

[0004] The above technical solution absorbs the oil in the electroplating degreasing waste liquid by rotating the diatomaceous earth plate and the zeolite plate, thereby achieving the purpose of reducing the oil in the electroplating degreasing waste liquid. However, the diatomaceous earth plate and the zeolite plate have limited adsorption capacity for the oil. When the installed diatomaceous earth plate and the zeolite plate are fully adsorbed with the oil, they need to be cleaned and replaced, resulting in a slow treatment efficiency of the electroplating degreasing waste liquid. Moreover, since the oil content in each batch of electroplating degreasing waste liquid is different, the treatment effect of the electroplating degreasing waste liquid is uncertain by adsorbing the oil through the diatomaceous earth plate and the zeolite plate. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent treatment system for electroplating degreasing waste liquid, which can continuously treat the electroplating degreasing waste liquid, monitor the treatment status of the electroplating degreasing waste liquid, and improve the treatment effect of the electroplating degreasing waste liquid.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] An intelligent treatment system for electroplating degreasing waste liquid, comprising a liquid supply tank, an oil-liquid separation tank, a sludge tank, an oil-liquid tank and a control mechanism, the liquid supply tank is respectively connected with a liquid infusion pipe and a liquid supply pipe for providing electroplating degreasing waste liquid, the liquid infusion pipe is connected with the oil-liquid separation tank, the liquid infusion pipe is connected with a first liquid supply pump, a first temperature sensor for detecting the temperature of the electroplating degreasing waste liquid is arranged on a side wall of the liquid supply tank, and a temperature regulating mechanism for regulating the internal temperature of the liquid supply tank is arranged on an outer side wall of the liquid supply tank;

[0008] A first partition is provided at the bottom of the oil-liquid separation tank, and a second partition is provided on the inner side wall of the oil-liquid separation tank. The first partition and the second partition divide the oil-liquid separation tank into an air flotation chamber, a solid-liquid chamber and an oil-liquid chamber. A plurality of through holes are provided on the upper side of the first partition. The liquid infusion pipe is connected with the air flotation chamber. An oil measuring instrument for detecting the oil content in the waste liquid is installed on the side wall of the air flotation chamber. The detection end of the oil measuring instrument faces the air flotation chamber. An electrode plate for electrolytic electroplating degreasing waste liquid is installed at the bottom of the air flotation chamber. A protective frame is fixedly connected to the top of the oil-liquid separation tank. An oil suction mechanism for sucking out the oil and a camera for collecting images inside the oil-liquid separation tank are provided on the inner side wall of the protective frame. The oil suction mechanism is connected with the oil-liquid tank.

[0009] The solid-liquid cavity and the oil-liquid cavity are respectively connected with a water pipe and an oil pipe, which are respectively connected with a water pump and an oil pump, the oil pipe is connected with an oil-liquid pool, and the bottom of the solid-liquid cavity is connected with a mud discharge pipe, which is connected with a sludge pool;

[0010] The control mechanism includes a processing module and a current control module. The processing module is signal-connected to the current control module. The processing module is signal-connected to the first liquid supply pump, the first temperature sensor, the temperature adjustment mechanism, the oil suction mechanism, the camera, the oil measuring instrument, the water pump and the oil pump respectively. The current control module is electrically connected to the positive and negative poles of the electrode plate.

[0011] The technical principles of the above scheme are as follows:

[0012] The temperature of the electroplating degreasing waste liquid is detected by the first temperature sensor, and the temperature of the electroplating degreasing waste liquid in the liquid supply pool is controlled by the temperature regulating mechanism through the processing module according to the detected temperature, so that the oil in the electroplating degreasing waste liquid is melted and the oil in a solidified state is easier to handle.

[0013] The electroplating degreasing waste liquid is electrolyzed by electrode plates, oxygen is generated at the positive electrode of the electrode plate, and hydrogen is generated at the negative electrode of the electrode plate. Hydrogen and oxygen float up in the electroplating degreasing waste liquid in the form of fine bubbles. No turbulence is generated during the floating of the fine bubbles, so that the oil in the electroplating degreasing waste liquid does not produce a large flow, and more oil in the electroplating degreasing waste liquid is attached to the bubbles and brought to the surface of the electroplating degreasing waste liquid. At the same time, redox reaction occurs in the electrolysis process of the electroplating degreasing waste liquid, so the electroplating degreasing waste liquid is sterilized and decolorized.

[0014] The oil content in the electroplating degreasing waste liquid in the flotation chamber is monitored by an oil measuring instrument. When the oil content is high, the electrode plate current is increased through the current control module to generate more oxygen and hydrogen (fine bubbles) at the positive and negative electrodes of the electrode plates, thereby improving the efficiency of oil flotation; as the oil content decreases, the electrode plate current is reduced through the current control module, slowly allowing the residual oil in the electroplating degreasing waste liquid to float, thereby saving energy.

[0015] The electroplating degreasing waste liquid after electrolysis flows into the solid-liquid cavity through the through hole, and is discharged from the oil-liquid separation tank through the water pump after sedimentation. At the same time, the amount of oil on the surface of the oil-liquid separation tank is collected through the camera. When the amount of oil reaches a certain amount, the oil suction mechanism adsorbs the oil floating on the surface of the oil-liquid separation tank. The adsorbed oil is transported to the oil tank and from the oil tank to the oil tank. The sediment at the bottom of the oil-liquid separation tank is transported to the sludge tank.

[0016] The above scheme has the following beneficial effects:

[0017] 1. Compared with the prior art, this solution can continuously treat the electroplating degreasing waste liquid by electrolyzing the electroplating degreasing waste liquid. In the process of treating the oil in the waste liquid, the oil content in the waste liquid is monitored to ensure that the treatment of the electroplating degreasing waste liquid meets the standard. At the same time, the current passed through the electrode plate is adjusted according to the oil content in the waste liquid, which saves more energy. In addition, in the early stage of electrolysis of the waste liquid, due to the high oil content inside it, a large current will be passed through the electrode plate for electrolysis. During the large current electrolysis process, a strong redox reaction will be generated in the waste liquid, causing the bacteria in the waste liquid to be deprived of oxygen and inactivated, thereby sterilizing the waste liquid and making the discharged electroplating degreasing waste liquid more environmentally friendly.

[0018] 2. Compared with the prior art, this solution generates micron-level tiny bubbles around the electrode plates during the electrolytic electroplating degreasing wastewater process. The tiny bubbles can more effectively adsorb the oil in the wastewater. At the same time, compared with the bubbles generated by directly introducing gas into the wastewater, the micron-level tiny bubbles are not easy to generate turbulence during the floating process, making the wastewater relatively stable during the degreasing process, and the oil inside it is more easily adsorbed by the bubbles. On the other hand, the tiny bubbles produced by electrolysis carry an electric charge, and the pollutants in the wastewater also carry an electric charge. The tiny bubbles can adsorb some of the pollutants in the wastewater while adsorbing the oil, thereby preliminarily purifying the wastewater.

[0019] 3. Compared with the prior art, this solution carries the oil and some pollutants in the waste liquid to the surface of the waste liquid by adsorption of tiny bubbles. Since the diameter of the bubbles is very small, the oil and pollutants floating on the surface of the waste liquid are in foamy form, which makes it easier to remove the foamy oil and pollutants. At the same time, the foamy oil and pollutants are easier to separate from the wastewater, thereby effectively avoiding collecting the treated wastewater together with the oil and pollutants.

[0020] In summary, the present invention can continuously treat the electroplating degreasing waste liquid and monitor the treatment status of the electroplating degreasing waste liquid, thereby improving the treatment effect of the electroplating degreasing waste liquid, and the treated wastewater is more environmentally friendly.

[0021] Furthermore, a cover is provided on the top of the liquid supply tank, a first motor is installed on the upper end of the cover, the output shaft of the first motor passes through the cover, the output shaft of the first motor is coaxially fixedly connected with a stirring shaft, and the upper and lower sides of the stirring shaft are respectively fixedly connected with spiral blades with opposite rotation directions.

[0022] Beneficial effect: By rotating the spiral blades in opposite directions, the waste liquid on the upper side of the liquid supply pool and the waste liquid on the lower side collide and mix in the middle position of the liquid supply pool, so that the oil and water are fully mixed, so that the oil in the subsequent wastewater can be adsorbed by the bubbles generated by electrolysis.

[0023] Furthermore, the temperature regulating mechanism includes a temperature control ring arranged on the outer wall of the liquid supply tank, a hot water tank for supplying heating water and a cold water tank for supplying cooling water. The inner wall of the temperature control ring is in contact with the outer wall of the liquid supply tank. A spiral groove is provided on the inner wall of the temperature control ring. The uppermost end and the lowermost end of the spiral groove are respectively connected to an inlet pipe and a drain pipe. Both the inlet pipe and the drain pipe are connected to a three-way solenoid valve. Both the inlet pipe and the drain pipe are connected to the hot water tank and the cold water tank through the three-way solenoid valve. A second liquid supply pump is connected between the three-way solenoid valve on the water inlet pipe and the spiral groove. Both the three-way solenoid valve and the second liquid supply pump are connected to the signal of the processing module.

[0024] Beneficial effect: According to the temperature detected by the first temperature sensor, when the temperature of the waste liquid in the liquid supply tank exceeds the threshold range, a control signal is sent to the three-way solenoid valve and the second liquid supply pump through the processing module, thereby supplying heating water or cooling water to the spiral groove, and adjusting the temperature of the waste liquid in the liquid supply tank by heat exchange, preheating the waste liquid in the liquid supply tank and keeping it at a relatively suitable temperature, so that the oil in the waste liquid is in a melted state, which is convenient for subsequent processing.

[0025] Furthermore, a second temperature sensor is disposed on the side wall of the air flotation chamber, and the second temperature sensor is signal-connected to the processing module.

[0026] Beneficial effect: Since the waste liquid needs to pass through the infusion pipe when being transported from the liquid supply tank to the oil-liquid separation tank, the temperature of the waste liquid transported to the oil-liquid separation tank is detected by the second temperature sensor and compared with the temperature detected by the first temperature sensor to obtain the temperature difference of the waste liquid. If the temperature difference is too large, the temperature in the liquid supply tank is maintained at a higher temperature level through the temperature adjustment mechanism to avoid the oil in the waste liquid from solidifying in the infusion pipe, and at the same time to avoid the waste liquid transported to the oil-liquid separation tank having a temperature that is too low and inconvenient for oil separation.

[0027] Furthermore, the infusion tube is connected to a flow regulating valve, and the flow regulating valve is connected to the processing module signal.

[0028] Beneficial effect: According to the oil content in the waste liquid in the flotation chamber detected by the oil measuring instrument, when the oil content in the waste liquid is high, a control signal is sent to the flow regulating valve through the processing module, and the flow regulating valve reduces the flow of the waste liquid to the flotation chamber, so that the oil in the waste liquid in the flotation chamber can be fully separated, and then the flow of the waste liquid to the flotation chamber is increased, so that the oil in the waste liquid can be fully processed.

[0029] Furthermore, the oil suction mechanism includes a servo motor fixedly connected to the top of the protective frame at the top, the servo motor signal is connected to a motor controller, the motor controller is connected to the processing module signal, the servo motor output shaft is coaxially fixedly connected to a turbine, a ball screw is provided on the inner wall of the protective frame, the screw of the ball screw is rotatably connected to the inner wall of the protective frame, the screw of the ball screw is coaxially fixedly connected to a worm near one end of the servo motor, the worm is rotatably connected to the inner wall of the protective frame, the worm is meshed with the turbine, the nut of the ball screw is fixedly connected to the oil suction part, limiting handles are provided on both sides of the oil suction part, limiting grooves are provided on the side walls of the protective frame, the limiting handles are slidably matched with the limiting grooves, the oil suction part is connected to a negative pressure pump, the negative pressure pump is connected to the processing module signal, and the negative pressure pump is connected to the oil cavity.

[0030] Beneficial effect: The position of the oil floating on the surface of the waste liquid is determined according to the waste liquid image taken by the camera, and the servo motor rotates to make the oil suction part move laterally to reach the position with oil, and the oil is sucked into the oil cavity by the negative pressure pump. In this way, the oil is sucked at a fixed point, and the oil suction at the position without oil is reduced, thereby reducing the energy consumption of the oil suction mechanism.

[0031] Furthermore, a liquid level sensor is provided on the side wall of the oil chamber, and the liquid level sensor is connected to the processing module signal.

[0032] Beneficial effect: The amount of oil in the oil cavity is monitored by a liquid level sensor. When the oil reaches a certain amount, the oil in the oil cavity is completely transported to the oil pool through the oil pump to avoid long-term continuous operation of the oil pump.

[0033] Furthermore, the water supply pipe is connected to the filter tank, which is detachably connected to a cover body. A water inlet is provided on the top of the cover body, and a drain outlet is provided at the bottom of the filter tank. The water supply pipe is connected to the water inlet, and a plurality of filter plates are detachably connected to the inner wall of the filter tank from top to bottom.

[0034] Beneficial effect: The wastewater after oil removal is filtered again through the filter plate to further remove the oil in the wastewater, thereby improving the treatment effect of the oil in the wastewater.

The electrode plate 107 is composed of a plurality of positive plates and a plurality of negative plates. A protective frame 1 is fixedly connected to the top of the oil separation tank 4. The protective frame 1 has the same opening shape as the oil separation tank 4.

The model of the camera 102 is MC-FSB-10, and the oil suction mechanism is connected to the oil tank 25.

[0049] The solid-liquid chamber 110 and the oil-liquid chamber 113 are respectively connected to a water pipe 28 and an oil pipe 26. The water pipe 28 is located in the middle of the side wall of the solid-liquid chamber 110, and the oil pipe 26 is located in the middle of the side wall of the oil-liquid chamber 113.

[0050] The control mechanism includes a processing module, a current control module and a control cabinet 20. The processing module and the current control module are both installed in the control cabinet 20. The processing module is signal-connected to the current control module. The processing module adopts a single-chip microcomputer, the specific model is STC12C5A60S2, and the current control module model is ZT-03C. The processing module is signal-connected to the first liquid supply pump 19, the first temperature sensor 10, the temperature adjustment mechanism, the oil suction mechanism, the camera 102, the water pump 23 and the oil pump 27 respectively. The current control module is electrically connected to the positive and negative poles of the electrode plate 107, and the oil detection module is signal-connected to the oil measuring instrument 105.

[0051] The specific implementation process is as follows:

[0052] First, the electroplating degreasing waste liquid is transported to the liquid supply tank 11 through the liquid supply pipe, and the first temperature sensor 10 detects the real-time temperature of the electroplating degreasing waste liquid. In this embodiment, the temperature of the electroplating degreasing waste liquid in the liquid supply tank 11 is preset to 60°C through the processing module. When the first temperature sensor 10 detects that the temperature of the electroplating degreasing waste liquid in the liquid supply tank 11 is lower than 60°C, the processing module controls the temperature regulating mechanism to heat the electroplating degreasing waste liquid to melt the oil in the electroplating degreasing waste liquid.

[0053] When the electroplating degreasing waste liquid reaches a preset temperature, the first liquid supply pump 19 is driven by the processing module to transport the electroplating degreasing waste liquid in the liquid supply tank 11 to the air flotation chamber 106 in the oil-liquid separation tank 4. At the same time, the electrode plate 107 is controlled by the processing module to start, and the electrode plate 107 electrolyzes the electroplating degreasing waste liquid, generating oxygen at the positive electrode of the electrode plate 107 and hydrogen at the negative electrode of the electrode plate 107. The hydrogen and oxygen float in the electroplating degreasing waste liquid in the form of bubbles, and the oil in the electroplating degreasing waste liquid is removed. The bubbles are carried to the surface of the electroplating degreasing waste liquid, and the oil content in the electroplating degreasing waste liquid in the flotation chamber 106 is monitored by the oil measuring instrument 105. When the oil content is high, the current of the electrode plate 107 is increased through the current control module, so that more oxygen and hydrogen are generated at the positive and negative electrodes of the electrode plate 107, thereby improving the efficiency of the oil floating; as the oil content decreases, the current of the electrode plate 107 is reduced through the current control module, and the residual oil in the electroplating degreasing waste liquid is slowly floated.

[0054] Subsequently, the oil on the surface of the electroplating degreasing waste liquid is sucked out by the oil suction mechanism, and the oil is collected in the oil chamber 113. The oil in the oil chamber 113 is transported to the oil pool 25 for storage through the oil pump 27 and the oil pipe 26; the electroplating degreasing waste liquid passes through the flotation chamber 106 and enters the solid-liquid chamber 110, and the sediment in the electroplating degreasing waste liquid passes through the filter screen 109 and is deposited at the bottom of the solid-liquid chamber 110, and is finally transported to the sludge pool 21 for storage through the sludge discharge pipe 22, and the remaining electroplating degreasing waste liquid is discharged from the oil-liquid separation tank 4 through the water pump 23 and the water supply key.

[0055] Embodiment 2: As shown in the attached Figure 3 As shown: Compared with the first embodiment, the difference lies in that the top of the liquid supply tank 11 is detachably connected with a cover body 7, the upper end of the cover body 7 is installed with a first motor 6, the output shaft of the first motor 6 passes through the cover plate, the output shaft of the first motor 6 is coaxially fixedly connected with the stirring shaft 202 through a coupling, and the upper side and the lower side of the stirring shaft 202 are respectively welded and fixed with spiral blades 201 with opposite rotation directions.

[0056] The specific implementation process is as follows: the first motor 6 drives the stirring shaft 202 and the spiral blade 201 to rotate to stir and mix the electroplating degreasing waste liquid in the liquid supply box, thereby accelerating the temperature regulation of the electroplating degreasing waste liquid; the spiral blades 201 that rotate in opposite directions rotate the spiral blades 201 in opposite directions to cause the waste liquid on the upper side of the liquid supply tank 11 and the waste liquid on the lower side to collide and mix in the middle position of the liquid supply tank 11, so that the oil and water are fully mixed, so that the oil in the subsequent wastewater can be adsorbed by the bubbles generated by electrolysis.

[0057] Embodiment 3: As shown in the attached Figure 3 As shown in the figure, compared with the second embodiment, the difference is that the temperature adjustment mechanism includes a temperature control ring 9 sleeved on the outer wall of the liquid supply tank 11, a hot water tank 14 for supplying heating water and a cold water tank 13 for supplying cooling water. The inner wall of the temperature control ring 9 is in contact with the outer wall of the liquid supply tank 11. The inner wall of the temperature control ring 9 is provided with a spiral groove 203. A space for the flow of heating water and cooling water is formed between the spiral groove 203 and the outer wall of the liquid supply tank. The uppermost and lowermost ends of the spiral groove 203 are connected to each other. The ends are respectively connected to a water inlet pipe 17 and a drain pipe 16, and the water inlet pipe 17 and the drain pipe 16 are both connected to a three-way solenoid valve 15. The model of the three-way solenoid valve 15 is 231D-25C. The water inlet pipe 17 and the drain pipe 16 are both connected to the hot water tank 14 and the cold water tank 13 through the three-way solenoid valve 15. A second liquid supply pump 12 is connected between the three-way solenoid valve 15 on the water inlet pipe 17 and the spiral groove 203. The three-way solenoid valve 15 and the second liquid supply pump 12 are both connected to the processing module signal.

[0058] The specific implementation process is as follows:

[0059] When the temperature of the waste liquid in the liquid supply tank 11 exceeds the threshold range, a control signal is sent to the three-way solenoid valve 15 and the second liquid supply pump 12 through the processing module. When heating is required, a passage is formed between the hot water tank 14 and the spiral groove 203. When cooling is required, a passage is formed between the cold water tank 13 and the spiral groove 203, thereby supplying heating water or cooling water to the spiral groove 203. The temperature of the waste liquid in the liquid supply tank 11 is adjusted by heat exchange, and the waste liquid in the liquid supply tank 11 is preheated and kept at a relatively suitable temperature, so that the oil in the waste liquid is in a melted state, which is convenient for subsequent processing.

[0060] Embodiment 4: As shown in the attached Figure 1 and attached Figure 2 As shown: Compared with the third embodiment, the difference is that a second temperature sensor 104 is fixedly installed on the side wall of the flotation chamber 106 by screws, the model of the second temperature sensor 104 is SITRANS TS500, and the detection end of the second temperature sensor 104 extends into the electroplating degreasing waste liquid in the flotation chamber 106, and the second temperature sensor 104 is connected to the processing module signal.
