Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and in particular relates to a condensed water treatment structure for an anodizing tank. Background Art

[0002] Anodic oxidation is used for electrochemical oxidation of metals or alloys. It is an electrolytic oxidation process, in which the surface of aluminum and aluminum alloys is usually converted into an oxide film, which has protective, decorative and some other functions. Anodic oxidation is to use the metal or alloy as the anode and form an oxide film on its surface by electrolysis. The metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, protecting the metal surface, etc. Generally speaking, aluminum or aluminum alloy is used as the anode, and lead plate is selected as the cathode. The aluminum and lead plate are placed together in an aqueous solution formed by sulfuric acid and / or oxalic acid and / or chromic acid for electrolysis, so that an oxide film is formed on the surface of the aluminum and lead plate.

[0003] Since the temperature in the anodizing tank will affect the growth rate of the oxide film, the growth rate of the oxide film will be faster when the temperature is high, and the growth rate of the oxide film will be slower when the temperature is low. Therefore, in order to increase the anodizing speed, the temperature of the aqueous solution (anodizing solution) in the tank will be higher; because of the high temperature, the chemical agent in the tank will vaporize, and when it contacts the inner wall in the working environment, the gas will liquefy and form condensed water because the inner wall temperature in the working environment is low.

[0004] In the existing technology and applications, the condensed water produced by the volatilization of chemical agents is usually not collected and processed, which causes the volatilized gas of chemical agents in the working environment to stay in the space. Once the volume of the gas is large, it will affect the sight of the staff. And because the gas is produced by chemical agents, the staff will feel uncomfortable after inhaling the gas, and it may affect human health in the long run. In addition, when the volatilized chemical agents adhere to the ceiling of the working environment, condensed water will be formed, which will corrode the equipment above the tank body and affect the operation of the staff in the working environment; and after the condensed water gathers and falls into the tank body, it will pollute the aqueous solution in the tank body and destroy its pH.

[0005] Therefore, designing a condensate water treatment structure for anodizing tanks is an important technical problem that technicians in this field need to solve. Utility Model Content

Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0028] like Figure 1 As shown, the utility model discloses a condensate treatment structure for an anodizing tank, comprising a tank body 1 for anodizing treatment or cleaning equipment, a waste gas treatment module 2 for treating the gas generated by the volatilization of chemical agents, and a waste liquid treatment module 3 for treating the anodizing liquid treatment or cleaning liquid. The waste gas treatment module 2 at least comprises an exhaust pipe 21 and a purification device 23 arranged on the exhaust pipe 21. The tank body 1 is provided with a group of notch airways 11 connected to the exhaust pipe 21; the volatilized chemical agents in the tank body 1 are transported to the waste gas treatment module 2 via the exhaust pipe 21, and are discharged after being filtered by the purification device 23. A group of notch airways are arranged at the notch of the tank body, so that part of the volatilized gas in the tank body can be discharged outward through the notch airways, reducing the amount of volatilized gas in the operating space, thereby playing a role in protecting the working environment; at the same time, reducing the generation of condensate in the working environment.

[0029] Furthermore, an exhaust pipe 22 is disposed directly above the tank body 1, and the exhaust pipe 22 is connected to the exhaust pipe 1 21, and its output port is located at the air inlet of the exhaust gas treatment module 2. The chemical agent gas volatilized in the tank body is further collected through the exhaust pipe 2 to reduce the volume and residence time of the gas in the working environment and purify the working environment. Figure 1 to Figure 2As shown, the exhaust pipe 22 is preferably made of a plastic plate with a smooth surface made of PP polypropylene material; it includes an air inlet 221 and a pipe 222 that are integrally arranged; wherein the air inlet 221 is in a conical shape that is narrow at the bottom and wide at the top; an angle of not less than 18° is formed between the inclined surface of the air inlet 221 and the pipe 222. After multiple tests, the results show that when the angle between the air inlet 221 and the pipe 222 is not less than 18°, the condensed water attached to the air inlet 221 will slide down along the inclined inner surface thereof, and will not fall vertically under its own weight, thereby not affecting the operation of the staff, and will not pollute the pH value of the cleaning liquid or anodizing liquid inside the tank due to the condensed water falling into the tank.

[0030] Furthermore, liquid collecting tanks 5 for collecting condensed water are provided on both sides of the air inlet 221. Figure 1 As shown, in this application, it is preferred that the outer wall of the collecting tank 5 is coplanar with the outer wall of the air inlet 221; of course, in other embodiments, the shape of the collecting tank 5 can be adjusted according to the use requirements, and its specific structure is not limited here. The liquid inlet of the collecting tank 5 is connected to the side wall of the air inlet 221; the liquid outlet of the collecting tank 5 is located above the ceiling of the building and is lower than the height of the liquid inlet, so as to discharge the condensed water in the collecting tank 5. It can be seen that when the condensed water in the collecting tank 5 is collected to the height of the liquid outlet, the condensed water will be discharged from the liquid outlet. In this application, it is preferred that the liquid outlet of the collecting tank 5 is coplanar with its bottom surface. The liquid outlet is connected to the condensation drain pipe 51, and the output end of the condensation drain pipe 51 is connected to the wastewater treatment module 3; that is, the condensed water discharged from the condensation water pipe 51 will flow into the wastewater treatment module 3 for the same treatment, which effectively prevents the direct discharge of wastewater from causing environmental pollution and plays a role in green environmental protection.

[0031] The bottom of the trough body 1 is connected to the wastewater treatment module 3 through a drain pipe 13, and the wastewater in the trough body 1 is discharged after being treated by the wastewater treatment module 3. In order to facilitate the rapid emptying of the anodized water or cleaning liquid in the trough body 1, the present application preferably tilts the bottom of the trough body 1, and the tilt angle includes but is not limited to 1.5±0.2°. The wastewater treatment module 3 includes a water valve 31, a wastewater tank 32, a water pump 33 and a wastewater treatment system arranged on the outside of the trough body 1; they are connected through the drain pipe 13. Open the water valve 33 to eject the liquid that has been anodized or cleaned in the trough body 1, and it flows through the drain pipe 13 and the wastewater tank 32, and finally enters the wastewater treatment system. The wastewater tank 32 can store a certain amount of wastewater, and continue to output wastewater to the wastewater treatment system after the wastewater treatment system has processed the wastewater therein; or the wastewater can be output to the wastewater treatment system at a regular time and in a fixed quantity through the wastewater tank 32, which is an effective way to prevent the wastewater treatment system from directly discharging a certain amount of wastewater due to excessive wastewater, or damaging the wastewater treatment system and other adverse effects.

[0032] Furthermore, the liquid outlets of the condensate drain pipe 51 and the drain pipe 13 are connected to the wastewater pool 32; that is, the wastewater pool 32 collects the condensate and wastewater discharged from the condensate drain pipe 51 and the water valve 31; the wastewater in the tank body and the condensate volatilized by the chemical agent and attached to the inner wall of the air inlet pipe are uniformly collected through the wastewater pool, and after collection, they are uniformly transported to the wastewater treatment system for waste liquid treatment and then discharged, effectively preventing direct discharge of waste gas and waste liquid from causing environmental pollution or adverse effects on the human body. The wastewater treatment system uses physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, achieve the purpose of wastewater recovery and reuse, and make full use of water resources; since the wastewater treatment system is a known prior art, it will not be described here.

[0033] like Figure 1As shown, the exhaust gas treatment module 2 also includes an induced draft fan 24 arranged at the end of the purification device 23; and the output ports of the exhaust pipe 1 21 and the exhaust pipe 2 22 are connected to the inlet end of the purification device 23 and / or the induced draft fan 24; and finally discharged from the exhaust pipe 3 25. The gas output from the exhaust pipe 1 21 and the exhaust pipe 2 2 is purified in the purification device 23 by the induced draft fan 24, effectively reducing the waste gas generated by the volatilization of chemical agents and staying in the working environment. Further, the purification device 23 at least includes a filter for filtering harmful substances or suspended particulate matter in the gas, and the filter includes but is not limited to activated carbon. The purification device mainly refers to the treatment of industrial waste gas generated in the working environment, including gas generated by the volatilization of chemical agents, dust particles, odorous gas, toxic and harmful gas, etc. The gas purified by the purification device 23 can be directly discharged into the air without affecting the environment and human health.
