Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electroplating water circulation technology, and more specifically, it relates to water circulation treatment equipment for electroplating alumina. Background Technology
[0002] Electroplating alumina is widely used in many fields such as machinery manufacturing, electronics, automobiles, and construction because it significantly improves the corrosion resistance, wear resistance, and decorative properties of aluminum products. After electroplating, alumina plating requires cleaning to facilitate subsequent processing, generating a large amount of wastewater. To reduce wastewater pollution and water waste, a water circulation treatment system for alumina plating is needed. Existing water circulation treatment systems for alumina plating mainly use a dual approach of physical and chemical filtration. Physical filtration primarily removes sediments, waste residues, and other impurities from the wastewater using filter screens, while chemical filtration separates heavy metal ions from the wastewater.
[0003] Existing application number CN202123281700.7 discloses a circulating electroplating tank, comprising an electroplating tank body, several stirring blades disposed within the tank body, a device box fixed to the outside of the tank body, a drive assembly connected to the stirring blades disposed within the device box, a purification box fixed within the device box, and a power assembly connected to the purification box within the device box. The power assembly is connected to the electroplating tank body, and an external pipe is fixed between the electroplating tank body and the purification box. A first solenoid valve is fixed to the outside of the external pipe, a shaft seat is fixed to the inner wall of the electroplating tank body, and an activated carbon filter screen is disposed within the purification box. This circulating electroplating tank utilizes an external pipe, a pumping pipe, and a guide pipe to guide the flow of water, operating a circulating water pump to achieve water circulation of the electroplating solution within the tank body. During the circulation of the electroplating solution, the activated carbon filter screen blocks impurities in the electroplating solution, preventing excessive impurities in the electroplating tank body.
[0004] Based on the above, in existing water circulation treatment equipment used for electroplating alumina, the filter screen becomes clogged with impurities after prolonged use during physical filtration. This requires regular removal and maintenance of the filter screen, which necessitates stopping filtration and replacing the filter screen, thus affecting filtration efficiency. Utility Model Content

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0028] Example 1:
[0029] As attached Figure 1 To be continued Figure 6 As shown:
[0030] This utility model provides a water circulation treatment device for electroplating alumina, including an electroplating cleaning tank 1; a slow-flow chamber 2, which is fixedly installed at the bottom of the electroplating cleaning tank 1; a physical filter chamber 3, which is fixedly installed at the bottom of the slow-flow chamber 2; a discharge port 4, which is fixedly installed at the front of the physical filter chamber 3; a biochemical filter chamber 5, which is fixedly installed at the bottom of the physical filter chamber 3; a water pump 6, which is fixedly installed at the top of the biochemical filter chamber 5; and a filter assembly, which is disposed at the bottom of the electroplating cleaning tank 1.
[0031] The filter assembly includes a flow buffer plate 201, which is provided in multiple sets. The multiple sets of flow buffer plates 201 are installed in an inclined and staggered manner inside the flow buffer chamber 2. Its function is to allow the wastewater inside the electroplating cleaning tank 1 to flow into the flow buffer chamber 2 through the water pipe and flow through the multiple sets of flow buffer plates 201 for buffering and slowing down.
[0032] The filter assembly also includes: a drive motor 301, which is fixedly installed on the back of the physical filter chamber 3; and a drive shaft 302, which is fixedly installed inside the drive motor 301 and is rotatably connected inside the physical filter chamber 3. Its function is that when the drive motor 301 is powered on, it drives the drive shaft 302 to rotate.
[0033] The filter assembly also includes: a drive roller 303, which is fixedly installed on the outside of the drive shaft 302; a driven roller 304, which is rotatably connected inside the physical filter chamber 3; and a filter screen 305, which covers the outside of the drive roller 303 and the driven roller 304. The function of the filter screen 305 is that the rotation of the drive shaft 302 drives the drive roller 303 to rotate, the rotation of the drive roller 303 drives the filter screen 305 to rotate, and the driven roller 304 guides the filter screen 305 when it rotates.
[0034] The specific usage and function of this embodiment are as follows:
[0035] When the wastewater inside the electroplating cleaning tank 1 needs to be filtered, the wastewater flows into the slow-flow chamber 2 through a water pipe. It then flows through multiple sets of slow-flow plates 201 for buffering and slowing the flow, preventing the wastewater from directly washing over the filter screen 305 and reducing its lifespan. The drive motor 301 is powered on, driving the drive shaft 302 to rotate. The drive shaft 302 rotates the drive roller 303, which in turn rotates the filter screen 305. The driven roller 304 guides the filter screen 305 as it rotates. The filter screen 305 filters the wastewater flowing into the physical filtration chamber 3. The continuous rotation of the filter screen 305 causes the wastewater to fall at different points, preventing blockages and damage caused by wastewater continuously falling on the same spot. This ensures that every position of the filter screen 305 is fully utilized. The wastewater filtered by the filter screen 305 falls into the biological filtration chamber 5 for treatment and is then pumped out by the water pump 6 for reuse or discharge.
[0036] Example 2:
[0037] Based on Example 1, such as Figures 1 to 6 As shown, it also includes:
[0038] The cleaning component is located inside the physical filter chamber 3.
[0039] The cleanup components include:
[0040] The slag discharge bin 309 is located inside the physical filtration bin 3 and is connected to the discharge port 4.
[0041] The conveying auger 308 is rotatably connected inside the slag discharge bin 309; its function is to allow the conveying auger 308 to rotate inside the slag discharge bin 309.
[0042] The cleanup component also includes:
[0043] The drive pulley 306 is fixedly installed on the outside of the drive shaft 302;
[0044] Driven pulley 307 is fixedly installed on the outer side of conveyor auger 308. Driven pulley 307 and drive pulley 306 are connected together by a belt. Its function is that the drive shaft 302 rotates to drive drive pulley 306 to rotate, drive pulley 306 to drive driven pulley 307 to rotate, and driven pulley 307 to drive conveyor auger 308 to rotate.
[0045] The cleanup component also includes:
[0046] The filter plate 310 is fixedly installed inside the slag discharge bin 309.
[0047] Water channel 311 is located at the bottom of slag discharge bin 309;
[0048] The scraper 312 is fixedly installed on the upper part of the slag discharge bin 309. Its function is that when the filter screen 305 rotates to the position of the scraper 312, the scraper 312 scrapes the surface of the filter screen 305, and the scraped residue falls into the slag discharge bin 309. The water filter plate 310 further filters out the water inside the residue, and the filtered water flows back into the biochemical filter bin 5 from the water channel 311 for treatment.
[0049] The specific usage and function of this embodiment are as follows:
[0050] When the filter screen 305 rotates to the scraper 312 position, the scraper 312 scrapes the surface of the filter screen 305, and the scraped residue falls into the slag discharge bin 309. The drive motor 301 drives the drive shaft 302 to rotate, and the drive shaft 302 drives the active pulley 306 to rotate. The rotation of the active pulley 306 drives the driven pulley 307 to rotate through the pulley. The rotation of the driven pulley 307 drives the conveying auger 308 to rotate. The rotation of the conveying auger 308 conveys the residue inside the slag discharge bin 309 and delivers the residue to the discharge port 4 for centralized collection and treatment. The water filter plate 310 further filters out the water inside during the residue conveying. The filtered water flows back into the biochemical filtration bin 5 from the water channel 311 for treatment.
