Description

Technical Field

[0001] The utility model relates to the field of electroplating waste gas treatment, in particular to an electroplating waste gas treatment structure. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics. In the electroplating process of industrial production, an industrial waste gas containing extremely high concentrations of toxic, harmful and difficult to degrade naturally is easily generated. Therefore, the waste gas needs to be purified before it can be discharged.

[0003] After searching, a publication number of CN220090956U disclosed an electroplating waste gas treatment tower, which includes a tower body, a circulating water tank is provided on the right side of the tower body near the bottom, a water outlet pipe is provided on the right side of the circulating water tank near the bottom, a water pump is provided on the right side of the water outlet pipe, a water supply pipe is provided on the top of the water pump, and a plurality of bearing structures are provided inside the tower body. A first packing layer, a second packing layer, a zeolite filter layer, a heating filter screen and an activated carbon filter layer are provided in sequence from bottom to top inside the tower body and at the top of the bearing structure, a spray pipe structure is provided above the first packing layer and the second packing layer and at the bottom of the bearing structure, through Due to the design of the heating structure, during use, the waste gas passing through the first packing layer and the second packing layer will become moist, thereby avoiding the problem that when the existing electroplating waste gas treatment tower treats the electroplating waste gas, the treated waste gas is moist waste gas, which is very easy to be polluted again in the treatment tower, thereby improving the treatment efficiency of the electroplating waste gas. However, in this scheme, the waste gas only flows upward along the tower body and is then gradually purified. When the impurities and particles in the waste gas are unevenly distributed, the device cannot fully disperse and mix the impurities and particles in the waste gas, resulting in incomplete waste gas treatment, and the exhausted gas will still have an impact on the air.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Specifically, when the exhaust gas needs to be fully mixed and cleaned, the exhaust gas collected in the collecting bucket 24 is transported to the bottom of the reaction tank 1 through the air inlet pipe 21. At the same time, the one-way valve 16 is opened to allow the water in the water storage tank 14 to flow to the diversion pipe 17 through the water delivery pipe 15 and sprayed to the inside of the reaction tank 1. The water contacts the particulate impurities in the exhaust gas, and the heavier particles in the exhaust gas fall into the filter screen 19 with the water flow. After filtering, the water flows back to the water storage tank 14, while the lighter exhaust gas is filtered by the filter plate 13 for preliminary purification. At the same time, the output end of the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring blade 6 and the first scraper 7 to rotate. The stirring blade 6 fully stirs the exhaust gas in the reaction tank 1 to disperse the particles in the exhaust gas. The first scraper 7 scrapes off the impurity particles adsorbed on the filter plate 13 to prevent the filter plate 13 from being blocked, and then the exhaust gas is further filtered and purified through the activated carbon plate 12 to accelerate the filtration rate of the exhaust gas. The shaft 5 drives the sleeve plate 9 to rotate through the connecting rod 8, and the sleeve plate 9 can drive the second scraper 10 to slide on the inner wall of the reaction tank 1, so as to facilitate the cleaning of the impurities remaining on the inner wall of the reaction tank 1. In this way, the exhaust gas can be fully stirred and broken up, and efficient exhaust gas recovery and cleaning are realized. At the same time, it is also convenient to clean the inside of the tank, improve the practicability of the treatment structure and the efficiency of exhaust gas treatment, can effectively purify the exhaust gas and protect the environment, and also provide a clean working environment for subsequent processes.

[0033] Reference Figure 1 , Figure 3 and Figure 4 An air inlet pipe 21 is fixedly connected inside the reaction tank 1, a collecting tube 22 is fixedly connected to the outer wall of the air inlet pipe 21, and a fan 23 is fixedly connected inside the collecting tube 22; a collecting bucket 24 is fixedly connected to the outer wall of the collecting tube 22, a plating tank 34 is arranged inside the collecting bucket 24, a partition 25 is fixedly connected inside the collecting bucket 24, and a cooling pipe 26 is fixedly connected inside the collecting bucket 24; a connecting seat 27 is fixedly connected inside the collecting bucket 24, a connecting shaft 28 is rotatably connected inside the connecting seat 27, and a side plate 29 is fixedly connected to the outer wall of the connecting shaft 28; a worm gear 30 is fixedly connected to the outer wall of the connecting shaft 28, and a rotating rod 31 is rotatably connected inside the collecting bucket 24; a worm 32 is fixedly connected to one end of the rotating rod 31, the worm 32 is meshed with the worm gear 30, and a knob 33 is fixedly connected to the other end of the rotating rod 31;

[0034] Specifically, when it is necessary to fully collect the exhaust gas, the fan 23 is turned on and the fan 23 starts working, and the exhaust gas is collected through the collecting bucket 24. The exhaust gas is effectively introduced into the processing structure through the collecting bucket 24, and then the worm 32 is driven to rotate by turning the knob 33. Since the worm 32 and the worm wheel 30 are meshed with each other, the rotation of the worm 32 will drive the worm wheel 30 to rotate, and the rotation of the worm wheel 30 will further drive the connecting shaft 28 to rotate inside the connecting seat 27. This process will also adjust the angle of the side plate 29, and the angle adjustment of the side plate 29 can be adjusted by adjusting the angle of the side plate 29. Angle is used to control the intake amount of exhaust gas. In this way, the position of the side panel 29 can be adjusted as needed to ensure that the exhaust gas can be fully collected. This makes it possible to adjust the intake amount to adapt to different exhaust gas concentrations and flow rates, thereby achieving the effect of fully collecting the exhaust gas. At the same time, it can not only effectively collect the exhaust gas and improve the comprehensiveness of the treatment structure, but also expand the application scope of the treatment structure. At the same time, it also helps to ensure the flexibility and efficiency of the exhaust gas collection process, and is suitable for various industrial scenarios, thereby improving the overall efficiency and effectiveness of exhaust gas treatment, and thus contributing to environmental protection and production safety.

[0035] Working principle: When the exhaust gas needs to be fully mixed and the inner wall of the reaction tank 1 needs to be fully cleaned, the exhaust gas collected in the collecting hopper 24 is transported to the bottom of the reaction tank 1 through the air inlet pipe 21, and then the one-way valve 16 is opened, so that the water flow in the water storage tank 14 can flow from the water delivery pipe 15 to the diversion pipe 17, and then sprayed to the inside of the reaction tank 1 by the spray head 18 to adsorb the particulate impurities in the exhaust gas. The heavier particles will fall into the filter 19 together with the water flow. After filtering, the water flow can flow back to the water storage tank 14 through the return pipe 20, while the lighter particles will be discharged from the water flow. The exhaust gas can be filtered by the filter plate 13, and then the exhaust gas is preliminarily purified. At the same time, the output end of the motor 4 drives the shaft 5 to rotate, so that the shaft 5 can drive the stirring blade 6 and the first scraper 7 to rotate, wherein the stirring blade 6 can fully stir the exhaust gas inside the reaction tank 1, and then disperse the impurities and particles that have agglomerated in the exhaust gas, and the first scraper 7 can scrape off the impurity particles adsorbed on the filter plate 13 to prevent the filter plate 13 from being blocked, and then the activated carbon plate 12 can further filter and purify the exhaust gas, thereby accelerating the exhaust gas. The filtration rate is increased, and the sleeve plate 9 is driven to rotate by the connecting rod 8 through the rotating shaft 5, so that the sleeve plate 9 can drive the second scraper 10 to slide on the inner wall of the reaction tank 1, so as to facilitate the cleaning of the reaction tank 1 and scrape off the impurities remaining on the inner wall of the reaction tank 1, thereby achieving the effect of fully stirring and breaking up the exhaust gas, realizing the efficient recovery of the exhaust gas, and also facilitating the cleaning of the inside of the tank, improving the practicality of the treatment structure and the efficiency of the exhaust gas treatment. When the exhaust gas needs to be fully collected, the fan 23 is turned on to make the wind The machine 23 can collect the exhaust gas by the collecting bucket 24, and then drive the worm 32 to rotate by turning the knob 33. Since the worm wheel 30 and the worm 32 are meshed with each other, the worm 32 can drive the worm wheel 30 to rotate, and then drive the connecting shaft 28 to rotate inside the connecting seat 27. At the same time, the angle of the side plate 29 can also be adjusted, so that the side plate 29 can control the exhaust gas intake volume by adjusting the angle, thereby achieving the effect of fully collecting the exhaust gas, improving the comprehensiveness of the treatment structure, and expanding the scope of application.
