Description

Technical Field

[0001] This utility model relates to the field of copper enrichment and recovery technology, specifically a copper enrichment and recovery device for wastewater treatment. Background Technology

[0002] Although existing copper ion enrichment and recovery equipment has been continuously innovated and developed to basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN215626955U discloses a copper ion concentration device for recovering copper sulfate from electrolytic wastewater, belonging to the field of wastewater recovery technology. It includes a support frame with a mounting plate fixedly installed near the center of the inner wall of the frame, and a concentration cylinder connected through the top of the mounting plate. Multiple sets of reverse osmosis tubes are installed to effectively concentrate free copper ions in the electrolytic wastewater, facilitating later collection and use, and improving resource utilization. A pressure plate that pressurizes the inside of the concentration cylinder effectively improves osmosis efficiency, allowing for rapid concentration. Connecting cylinders are installed on the outer wall of the reverse osmosis tubes for easy replacement, ensuring the equipment's osmosis effect. Collecting copper ions from wastewater effectively prevents environmental pollution, reduces resource waste, and protects the environment.

[0004] Although the aforementioned reverse osmosis concentration equipment pressurizes the water and improves the permeation efficiency through pressure plates, the concentrated water still requires manual assistance and external pipe connection when being discharged, and the overall concentration process is relatively long. Therefore, there is an urgent need for a copper enrichment and recovery device for wastewater treatment to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a copper enrichment and recovery device for wastewater treatment, so as to solve the problem mentioned in the background art that although the reverse osmosis concentration equipment pressurizes the water and improves the permeation efficiency through the pressure plate, the concentrated water still requires manual assistance to connect external pipes when draining, and the overall concentration process is long.

[0006] This utility model provides the following technical solution: a copper enrichment and recovery device for wastewater treatment, comprising a conveying mechanism, wherein the conveying mechanism includes a liquid supply pipe, a concentrated water pipe and a clear water pipe; It also includes several concentration mechanisms distributed between the liquid supply pipe, the concentrate pipe and the clear water pipe. The concentration mechanism includes a concentration pipe that is connected to the liquid supply pipe and the concentrate pipe on both sides and connected to the clear water pipe through an extension pipe. The inside of the concentration tube is fitted with a reverse osmosis membrane that is in close contact with the reverse osmosis membrane; Additionally, a cylinder-driven extrusion ring moves along the surface of the reverse osmosis membrane to pressurize the liquid inside the concentration tube, and an electrically controlled valve is installed in the passage between the concentration tube, the supply tube, and the concentrate tube.

[0007] To achieve the above technical solution, the reverse osmosis membrane and the extension tube are closely aligned, and the compression ring is used to squeeze the inside of the concentration tube, thereby compressing the internal space of the concentration tube and accelerating the reverse osmosis process. Compared with the existing technology, the concentration tube, concentrate tube, and supply tube of this device are equipped with electrically controlled valves, which makes it easy to push the concentrate directly into the concentrate tube without the need for secondary manual replacement of the pipes.

[0008] As a further improvement to this utility model, the concentration tube consists of a tank body and a tank cover fixed with bolts.

[0009] Implementing the above technical solution facilitates the replacement of reverse osmosis membranes.

[0010] As a further improvement to this utility model, the pipelines connecting the concentration pipe, the concentrate pipe, and the supply pipe are on the same horizontal line.

[0011] The above technical solution facilitates the entry and exit of water.

[0012] As a further improvement to this utility model, the inner and outer rings of the extrusion ring are in close contact with the outer wall of the reverse osmosis membrane and the inner wall of the concentration tube, respectively.

[0013] The above technical solution improves the sealing effect at the extrusion ring.

[0014] As a further improvement to this utility model, the cylinder is located outside the concentrator tube and connected to the surface of the extension tube.

[0015] The above technical solution reduces the impact of water on the cylinder.

[0016] As a further improvement to this utility model, the maximum stroke of the cylinder extension end is no more than half the height of the concentration tube.

[0017] The above technical solution aims to avoid excessive pressure inside the concentration tube.

[0018] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a reverse osmosis membrane and extension tube closely aligned, and a squeezing ring squeezes the inside of the concentration tube, thereby compressing the internal space of the concentration tube and accelerating the reverse osmosis process.

[0019] 2. Compared with the prior art, the present invention has an electrically controlled valve in the concentration pipe, concentrate pipe, and supply pipe of the device, which makes it easy to push the concentrate directly into the concentrate pipe without the need for secondary manual replacement of the pipe.

[0026] Example 1: Refer to the attached diagram in the instruction manual. Figure 1-3 This utility model provides a copper enrichment and recovery device for wastewater treatment, including a conveying mechanism 100, which includes a liquid supply pipe 110, a concentrated water pipe 111 and a clean water pipe 112. It also includes several concentration mechanisms 200 distributed between the liquid supply pipe 110, the concentrate pipe 111 and the clear water pipe 112. Each concentration mechanism 200 includes a concentration pipe 210 that is connected to the liquid supply pipe 110 and the concentrate pipe 111 on both sides and connected to the clear water pipe 112 through an extension pipe 211. A reverse osmosis membrane 212 is placed inside the concentration tube 210 and is in close contact with the reverse osmosis membrane 212. Additionally, a compression ring 213, driven by a cylinder 214, moves along the surface of the reverse osmosis membrane 212 to pressurize the liquid inside the concentration tube 210. An electrically controlled valve is installed in the passage between the concentration tube 210, the supply pipe 110, and the concentrate pipe 111. The inner and outer rings of the compression ring 213 are in close contact with the outer wall of the reverse osmosis membrane 212 and the inner wall of the concentration tube 210, respectively. The cylinder 214 is located outside the concentration tube 210 and connected to the surface of the extension tube 211.

[0027] In use, the electrically controlled valve of the pipeline connecting the supply pipe 110 and the concentration pipe 210 is opened, allowing water to enter the concentration pipe 210. The electrically controlled valve of the pipeline connecting the supply pipe 110 and the concentration pipe 210 is closed. The cylinder 214 pushes the squeezing ring 213 to squeeze the internal space of the concentration pipe 210, allowing part of the water to pass through the reverse osmosis membrane 212 and be discharged through the clear water pipe 112. Subsequently, the electrically controlled valve of the pipeline connecting the concentrate pipe 111 and the concentration pipe 210 is opened. As the squeezing ring 213 continues to move, the remaining concentrate is forced into the concentrate pipe 111 and discharged.

[0028] Example 2: Refer to the attached diagram in the instruction manual. Figure 3 The difference between this embodiment and the above embodiment is that the concentration pipe 210 is composed of a tank body and a tank cover fixed by bolts, and the pipelines connected to the concentration pipe 210, the concentrate pipe 111 and the liquid supply pipe 110 are on the same horizontal line.
