Description

Technical Field

[0001] This utility model mainly relates to the technical field of copper foil processing equipment, specifically a copper melting tank heat exchanger and energy recovery device. Background Technology

[0002] In the copper foil processing process, the copper melting pot is one of the important pieces of equipment. It generates a lot of heat when it is working. If this heat is not utilized, it will not only waste energy, but may also have an adverse impact on the normal operation of the equipment and the surrounding environment.

[0003] Currently, existing copper melting tanks have several problems in heat handling. Firstly, traditional copper melting tanks often lack efficient heat exchange and recovery devices, failing to effectively recover and utilize the heat generated during the copper melting process, resulting in low energy efficiency and increased energy consumption and costs in the production process. Secondly, existing heat exchange and recovery devices suffer from poor sealing performance when connected to the copper melting tank. Existing flange connection structures are prone to aging and leakage of the sealing rings under pressures of 0.5-1.0 MPa. Industry statistics show that the leakage rate of traditional connection methods is as high as 15%-20%, resulting in a heat loss of approximately 30-50 kWh per ton of copper foil produced, and potentially causing equipment corrosion and workshop safety hazards due to solution leakage. Therefore, a copper melting tank heat exchanger and energy recovery device are proposed. Utility Model Content

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please refer to the appendix carefully. Figure 1-5 A copper melting tank heat exchanger and energy recovery device are disclosed, comprising a copper melting tank 1, a liquid storage pipe on one side of the copper melting tank 1, an overflow port and a return port on the copper melting tank 1, and valve assemblies inside the overflow port and the return port. The overflow port and the return port valve assemblies are controlled by a DCS system, with a maximum and minimum line set. The opening degree of the valve assembly is automatically adjusted according to the copper concentration. During the process, the difference between the overflow flow rate and the return flow rate is set to prevent the liquid in the copper melting tank from being evacuated.

[0020] The outlet of the copper melting tank 1 is connected to the heat exchange and recovery device 3 via the conveying pipe 2. The heat exchange and recovery device 3 includes two end plates 301, and a plate assembly 302 is provided between the two end plates 301. The plate assembly 302 consists of heat exchange plates and sealing gaskets. The heat exchange plates are herringbone corrugated heat exchange plates, and sealing gaskets are provided between adjacent heat exchange plates. The two end plates 301 are connected by bolts, which can firmly fix the plate assembly 302 between the two end plates 301, ensuring that the entire heat exchange and recovery device 3 will not loosen or deform due to factors such as fluid pressure during operation, thus ensuring the stable operation of the heat exchange process. The end plates 301 are provided with four sets of openings, namely a refrigerant inlet, a refrigerant outlet, a heat medium inlet, and a heat medium outlet. The conveying pipe 2 is connected to the connecting pipe 4 at the heat medium inlet.

[0021] Connecting pipes 4 are installed at the refrigerant inlet, refrigerant outlet, heat medium inlet, and heat medium outlet of the heat exchange recovery device 3. One end of each connecting pipe 4 is inserted into the delivery pipe 2. A sealing groove is provided on the inner side of the end of the delivery pipe 2 to cooperate with the connecting pipe 4, and a sealing ring is provided on the inner side of the sealing groove. The sealing ring can be made of rubber. The elastic deformation of the sealing ring fills the gap between the connecting pipe 4 and the delivery pipe 2 to form a tight sealing surface, thereby preventing liquid leakage from the connection under pressure. A sealing cylinder 5 is fixedly installed on the outside of the connecting pipe 4, and a sealing layer is installed on the inner side of the sealing cylinder 5. The sealing layer is made of modified polytetrafluoroethylene (PTFE) material, reinforced with 15% carbon fiber, with a Shore hardness of 60-70A, a temperature resistance range of -20℃ to 260℃, and a corrosion rate of ≤0.01mm / s² for copper sulfate solution. To ensure long-term use in the highly corrosive environment of the copper melting tank, the connecting end of the conveying pipe 2 is located inside the sealing cylinder 5. Together, they form a closed space that encloses the connection between the conveying pipe 2 and the connecting pipe 4, further preventing liquid from leaking out from the gap at the connection. When the connecting end of the connecting pipe 4 does not need to be frequently disassembled, the sealing cylinder 5, the conveying pipe 2, and the connecting pipe 4 can be further limited by bolts, thereby further improving the connection firmness.

[0022] A number of lifting and pressing components 7 are installed on one side of the sealing cylinder 5 to cooperate with the limiting ring 6. The limiting ring 6 is set on the outer side of the connecting end of the conveying pipe 2. The lifting and pressing component 7 includes a mounting frame 701, and a lifting block 702 is slidably arranged inside the mounting frame 701. The mounting frame 701 is fixedly installed on the outer side of the connecting pipe 4, and the mounting frame 701 and the lifting block 702 can be detachably connected by bolts. When the bolts are removed, the lifting block 702 can move vertically inside the mounting frame 701. An open fixing groove 703 is installed on one side of the lifting block 702, and a screw mechanism 704 is rotatably arranged inside the open fixing groove 703. A handle is set on the outer side of the fixing groove 703 to drive the screw mechanism 704 to rotate. A limiting hole is opened on the handle. The position of the handle can be limited by the limiting component to prevent the handle from rotating on its own. The screw mechanism 704 can drive the contact block 705 slidably arranged inside the fixing groove 703 to move. The contact block 705 can contact the limiting ring 6.

[0023] The specific operating procedure of this utility is as follows: Align one end of the connecting pipe 4 at the heat medium inlet of the heat exchange recovery device 3 with the connecting end of the conveying pipe 2, so that the insertion end of the connecting pipe 4 corresponds to the sealing groove of the conveying pipe 2, ensuring that the two are basically aligned in the axial and radial directions to reduce installation errors. After being inserted into the designated position, the sealing cylinder 5 is then placed on the outside of the conveying pipe 2, ensuring that the sealing layer on the inside of the sealing cylinder 5 is tightly fitted with the connecting end of the conveying pipe 2.

[0024] After the above operations are completed, slide the lifting block 702 inside the mounting bracket 701 and adjust the position of the lifting block 702 so that the contact block 705 contacts the limiting ring 6. After contact, connect the lifting block 702 to the mounting bracket 701 with bolts to limit the height of the contact block 705.

[0025] After the contact block 705 is height-limited, rotate the throttle to drive the lead screw mechanism 704 to rotate, thereby moving the contact block 705 until the contact block 705 contacts the limiting ring 6 on the outside of the connecting end of the conveying pipe 2 and gradually presses against it, thereby limiting the position between the conveying pipe 2 and the connecting pipe 4, and improving the sealing of the connection.

[0026] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
