Description

Technical Field

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

[0002] Electroplating wastewater is industrial wastewater generated during the electroplating process, containing heavy metal ions, acids and alkalis, organic additives, and other pollutants. Wastewater and waste liquid discharged from electroplating plants contain large amounts of metal ions such as chromium, cadmium, and nickel, as well as cyanide, acids, and alkalis. They often contain organic additives. Since electroplating wastewater varies in type, treatment often requires separating different types of wastewater for treatment in different processes. However, the equipment cannot remotely and automatically open or close the diversion pipes of each group, making operation time-consuming and labor-intensive, affecting diversion efficiency. Furthermore, it cannot monitor wastewater flow, impacting subsequent wastewater volume statistics.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202123021947.5, application date 2021-12-03) provides a centralized control area electroplating wastewater diversion and treatment device, including a fixed base; a fixed frame is installed on the top left side of the fixed base, an inlet pipe is fixedly installed inside the fixed frame, a horizontal pipe is installed on the bottom right side of the inlet pipe, and a diversion pipe is installed on the right side of the horizontal pipe, with four groups of diversion pipes; data signals can be received or sent to the terminal through a wireless data transmission module, and the control module interface controls the opening or closing of each group of solenoid valves; the flow rate in each group of diversion pipes can be monitored through a flow meter, and the detection data can be transmitted to the terminal for display through the wireless data transmission module. This device can remotely complete the opening and closing of each diversion pipe, enabling more efficient and convenient diversion of different types of electroplating wastewater, greatly improving diversion efficiency, and simultaneously monitoring the wastewater volume in real time, thus facilitating wastewater volume statistics.

[0004] In the treatment of electroplating wastewater, various agents need to be added to remove pollutants. Stirring can make these agents spread quickly and evenly into the wastewater, increasing the contact opportunities between the agents and pollutants, and allowing the reaction to be completed in a shorter time. However, the above-mentioned device cannot stir the liquid inside the reaction tank during use, resulting in uneven distribution of microorganisms and organic matter in the reaction tank. Some microorganisms cannot come into contact with enough organic matter, which slows down the decomposition rate of organic matter and reduces the treatment efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a diversion and treatment device for electroplating wastewater, in order to solve the problem mentioned in the background art that the inability to stir the liquid inside the reaction tank leads to uneven distribution of microorganisms and organic matter in the reaction tank, and some microorganisms cannot come into contact with enough organic matter, resulting in a slower decomposition rate of organic matter and a decrease in treatment efficiency.

An air inlet pipe is fixedly connected to the surface of the catalyst box, and a discharge pipe is fixedly connected to the surface of the catalyst box.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the electroplating wastewater diversion and treatment device adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The electroplating wastewater diversion and treatment device improves the uniformity of the reaction by setting the stirring shaft and support frame, and at the same time allows the microorganisms to fully contact the organic matter in the wastewater, so that the microorganisms can decompose the organic matter more efficiently and greatly shorten the reaction time.

[0015] Furthermore, a uniform reaction reduces damage to the equipment caused by localized abnormal reactions and extends the service life of each component of the processing device.

[0016] (2) The electroplating wastewater diversion and treatment device improves the reaction efficiency of the device by setting a catalytic box and a one-way valve, enabling the device to adapt to water quality changes in a short time, reduce the concentration of pollutants to an acceptable level, and ensure that the quality of the treated wastewater is always kept at a high level.

[0017] Furthermore, this ensures the consistency of different batches of wastewater during the catalytic reaction process, while reducing the differences in treatment effects caused by fluctuations in reaction conditions.

[0018] (3) The electroplating wastewater diversion and treatment device improves the stability of the device by setting a sealing groove and a support frame, effectively reducing the shaking generated during the operation of the device, and at the same time reducing the friction generated during the operation of the device, thus improving the service life of the device.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: The stability of the device is improved by the design of the treatment pool 1, the sealing groove 7, and the fixing plate 16. Figures 1-3 As shown: It includes a treatment tank 1, a connecting pipe 2 fixedly connected to the surface of the treatment tank 1, and a valve body 3 bolted to the surface of the connecting pipe 2. A rotating shaft 5 is rotatably installed inside the valve body 3, and a sealing groove 7 is opened inside the valve body 3. A motor 4 is fixedly connected to the surface of the connecting pipe 2, and a rotating shaft 5 is fixedly connected to the output end of the motor 4. A valve plate 6 is threadedly connected to the surface of the rotating shaft 5, and the valve plate 6 is slidably installed on the surface of the sealing groove 7. A fixing plate 16 is fixedly connected to the surface of the treatment tank 1, and a catalyst box 17 is fixedly connected to the upper surface of the fixing plate 16. The catalyst boxes 17 are symmetrically distributed about the center of the treatment tank 1. A support rod 15 is fixedly connected to the inner wall of the treatment tank 1, and a support frame 12 is fixedly connected to the upper surface of the support rod 15.

[0029] The operator controls the flow rate of valve body 3 by starting motor 4, so that different types of wastewater generated during the electroplating process flow into the corresponding wastewater treatment tank 1 through their respective independent connecting pipes 2. Each treatment tank 1 is specifically used to collect specific types of wastewater to prevent different wastewaters from mixing and to ensure the accuracy of subsequent targeted treatment. When the wastewater reaches the treatment tank 1, the operator adds different catalysts to the inside of the catalytic tank 17 according to different chemical treatment types, thereby improving the reaction efficiency of the device. In addition, the setting of sealing groove 7 and support frame 12 improves the stability of the device, effectively reduces the shaking generated during the operation of the device, and also reduces the friction generated during the operation of the device, thereby improving the service life of the device.

[0030] Example 2: In this example, unlike Example 1, the uniformity of the reaction is improved by using the transmission shaft 8, support frame 12, and stirring shaft 13. Figures 4-5As shown: A motor 22 is fixedly connected to the surface of the treatment tank 1, and a transmission shaft 8 is fixedly connected to the output end of the motor 22. The transmission shaft 8 is rotatably disposed inside the treatment tank 1. A first gear 11 is fixedly connected to the surface of the transmission shaft 8, and a support frame 12 is movably connected to the surface of the transmission shaft 8. An agitator 13 is rotatably disposed inside the support frame 12, and a second gear 14 is fixedly connected to the surface of the agitator 13. The second gear 14 and the agitator 13 are evenly distributed about the inside of the support frame 12, and the second gear 14 is meshed with the first gear 11.

[0031] When the motor 22 is working, it drives the transmission shaft 8 at the output end to rotate, and the transmission shaft 8 drives the first gear 11 on the surface to rotate. The first gear 11 meshes with the second gear 14, driving the stirring shaft 13 to rotate inside the treatment tank 1. This causes the stirring shaft 13 to stir the liquid inside the treatment tank 1, which not only improves the reaction efficiency of the device, but also allows the device to adapt to changes in water quality in a short time, reducing the concentration of pollutants to an acceptable level, and ensuring that the quality of the treated wastewater is always maintained at a high level.

[0032] Example 3: In this example, unlike Example 2, the reaction rate of the device is accelerated by the addition of a catalytic converter 17, an intake pipe 20, and a one-way valve 19. Figures 6-7 As shown: A connecting rod 9 is fixedly connected to the surface of the drive shaft 8, and an upper push block 10 is fixedly connected to the lower surface of the connecting rod 9. The lower surface of the upper push block 10 is arc-shaped. A lower push block 18 is fixedly connected to the upper surface of the catalytic converter 17. The upper surface of the lower push block 18 is arc-shaped. An air inlet pipe 20 is fixedly connected to the surface of the catalytic converter 17. At the same time, a discharge pipe 21 is fixedly connected to the surface of the catalytic converter 17. A one-way valve 19 is fixedly connected to both the surface of the discharge pipe 21 and the surface of the air inlet pipe 20.

[0033] As the drive shaft 8 rotates, it drives the connecting rod 9 on the surface to rotate. When the upper push block 10 on the surface of the connecting rod 9 contacts the lower push block 18, the upper push block 10 squeezes the catalyst tank 17, causing the catalyst inside the catalyst tank 17 to flow from the feed pipe 21 into the treatment tank 1, thereby accelerating the reaction rate and improving the treatment efficiency of the device. At the same time, the one-way valve 19 installed on the surface of the feed pipe 21 ensures that the catalyst can only flow out in one direction, preventing it from flowing back into the catalyst tank 17, ensuring the stability and controllability of the catalyst flow, ensuring that the entire device can operate efficiently and stably, and accelerating the reaction efficiency of electroplating wastewater treatment.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
