Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a pretreatment device for copper foil processing wastewater. Background Technology
[0002] Copper foil is an anionic electrolytic material mainly used in the electronic information industry, such as printed circuit boards and copper-clad laminates. It is made by hammering copper with a certain proportion of other metals. It has good adhesion, can accept printed protective layers, and forms circuit patterns after etching. In the production process of copper foil, especially in the electrolysis, surface treatment and water washing processes, wastewater containing various inorganic salts, heavy metal ions (such as copper, zinc, nickel, cobalt and chromium) and organic matter is generated. This wastewater has a complex composition, high concentration, high toxicity, and is difficult to degrade. The water quality fluctuates greatly. Pretreatment is a necessary step for the wastewater generated by copper foil processing to reduce the burden of subsequent treatment and improve treatment efficiency. The current pretreatment of wastewater is to add chemical agents (such as sodium hydroxide and lime) to precipitate copper ions in the wastewater.
[0003] However, if these agents are poured directly into the wastewater at once, they tend to concentrate in localized areas, preventing copper ions from reacting evenly. To ensure that the agents are fully dispersed and react with copper ions, they need to be stirred for a long time using a stirring paddle to ensure that the copper ions can fully contact the agents and form a precipitate. This process may affect the precipitation of copper ions due to uneven stirring.
[0004] To address the aforementioned issues, this application proposes a pretreatment device for copper foil processing wastewater. Utility Model Content
[0005] Based on the technical problems existing in the background art, this utility model proposes a pretreatment device for copper foil processing wastewater.
[0006] This utility model proposes a pretreatment device for copper foil processing wastewater, which includes a pretreatment tank and a treatment cavity opened in the pretreatment tank. The pretreatment tank is equipped with a stirring paddle located in the cavity.
[0007] The inner wall of the pretreatment box is equipped with a guide component located in the area below the treatment chamber. One end of the guide component passes through the side of the pretreatment box, and a feeding component is installed on the path of one end of the guide component. An air supply component connected to one end of the guide component is installed on the side of the pretreatment box.
[0008] Preferably, the material guide includes a material guide pipe and a material discharge pipe. The material guide pipe is installed on the inner wall of the pretreatment box and located in the lower area of the treatment chamber. Several evenly distributed material discharge pipes are connected to the material guide pipe, and the bottom end of the material discharge pipe is bent downward.
[0009] Preferably, the feeding component includes a feeding pipe, a feeding box, and a valve body. One end of the feeding pipe passes through the side of the pretreatment box, the feeding pipe is connected to one end of the feeding pipe, the feeding box is connected to the feeding pipe, and a valve body for material control is installed on the feeding pipe.
[0010] Preferably, the air supply component includes an air pump and an air pipe. The air pump is installed on the side of the pretreatment box, and the air outlet of the air pump is connected to the air pipe. The end of the air pipe away from the air pump is connected to one end of the feed pipe.
[0011] Preferably, an assembly plate is installed on the top of the pretreatment box, a motor is installed on the assembly plate, the stirring paddle is located below the assembly plate, and the output end of the motor is connected to the top of the stirring paddle.
[0012] Preferably, the bottom of the pretreatment box is connected to a drain pipe that communicates with the treatment chamber, and a control valve is installed on the drain pipe.
[0013] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0014] 1. Through the setting of the guide component, feed component, and air supply component, the air supply component guides the gas into the guide component, and then the gas is guided into the treatment chamber along the guide component. Bubbles are generated in the wastewater in the treatment chamber. When the gas flows in the guide component, the feed component guides the powdered agent into the guide component. Under the action of the gas, the powder enters the wastewater in the treatment chamber along with the gas, and the powdered agent is dispersed with the bubbles generated in the treatment chamber. This structure uses gas to transport powdered chemical agents to the wastewater through the guide component. This method can make the agent form bubbles in the wastewater. As the bubbles rise and distribute, the agent is evenly dispersed throughout the wastewater, ensuring the wastewater treatment effect.
[0015] 2. This dispersion method avoids the concentration of the agent in a local area, increases the contact area between the agent and pollutants in the wastewater, thereby improving treatment efficiency and effectiveness. Since the agent is dispersed in the wastewater in the form of bubbles, this method reduces the time required for traditional agitation. The rising bubbles naturally drive the mixing of the agent, reducing reliance on mechanical stirring, thus saving energy consumption and time, and improving the efficiency of the treatment process.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0021] like Figure 1-3 As shown, the present invention proposes a pretreatment device for copper foil processing wastewater, which includes a pretreatment tank 1 and a treatment chamber 2 opened in the pretreatment tank 1. A stirring paddle 3 located in the cavity is installed on the pretreatment tank 1.
[0022] In this embodiment, a guide 4 located in the lower region of the processing chamber 2 is installed on the inner wall of the pretreatment box 1. The guide 4 includes a guide pipe 41 and a discharge pipe 42. The guide pipe 41 is installed on the inner wall of the pretreatment box 1 and located in the lower region of the processing chamber 2. Several evenly distributed discharge pipes 42 are connected to the guide pipe 41. The bottom end of the discharge pipe 42 is bent downward.
[0023] In this embodiment, one end of the guide 4 passes through the side of the pretreatment box 1, and a feeder 5 is installed on the path of one end of the guide 4. The feeder 5 includes a feed pipe 51, a feed box 52 and a valve body 53. One end of the guide pipe 41 passes through the side of the pretreatment box 1, and the feed pipe 51 is connected to the path of one end of the guide pipe 41. The feed box 52 is connected to the feed pipe 51, and a valve body 53 for material control is installed on the feed pipe 51.
[0024] In this embodiment, an air supply component 6 is installed on the side of the pretreatment box 1 and is connected to one end of the guide component 4. The air supply component 6 includes an air pump 61 and an air pipe 62. The air pump 61 is installed on the side of the pretreatment box 1, and the air outlet end of the air pump 61 is connected to the air pipe 62. The end of the air pipe 62 away from the air pump 61 is connected to one end of the guide pipe 41.
[0025] Gas can be pumped by air pump 61 and guided through air pipe 62 to feed pipe 41. The gas entering feed pipe 41 can be discharged through discharge pipe 42 and discharged into wastewater. Bubbles can be generated in the wastewater in treatment chamber 2. When the gas flows in feed pipe 41, the powdered agent in feed box 52 can be controlled by valve body 53 to fall into feed pipe 41 through feed pipe 51. Under the action of gas, the powdered agent can enter the wastewater in treatment chamber 2 along with the gas, and the powdered agent can be dispersed with the bubbles generated in treatment chamber 2. This structure uses gas to transport powdered chemical agents to wastewater through feed pipe 41. This method can make the agent form bubbles in the wastewater. As the bubbles rise and distribute, the agent is evenly dispersed throughout the wastewater, ensuring the wastewater treatment effect.
[0026] This dispersion method avoids the concentration of the agent in a local area, increases the contact area between the agent and pollutants in the wastewater, thereby improving the treatment efficiency and effect. Since the agent is dispersed in the wastewater in the form of bubbles, this method reduces the time required for traditional stirring paddles. The rising bubbles naturally drive the mixing of the agent, reducing the reliance on mechanical stirring, thus saving energy consumption and time, and improving the efficiency of the treatment process.
[0027] In a specific embodiment, an assembly plate 7 is installed on the top of the pretreatment box 1, a motor 8 is installed on the assembly plate 7, and a stirring paddle 3 is located below the assembly plate 7. The output end of the motor 8 is connected to the top of the stirring paddle 3.
[0028] To further promote the mixing of powdered reagents and wastewater, the stirring paddle 3 can be driven by motor 8 to rotate and stir the wastewater, thereby accelerating the mixing of reagents and wastewater.
[0029] In a specific embodiment, the bottom of the pretreatment tank 1 is connected to a drain pipe 9 that communicates with the treatment chamber 2, and a control valve is installed on the drain pipe 9. The drain pipe 9 facilitates the discharge of wastewater mixed with the reagent.
