Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically a compact heat exchanger. Background Technology

[0002] In food processing and pharmaceutical production, compact heat exchangers are used for heating, cooling, and sterilizing materials. In the food and beverage industry, they are used for pasteurization and cooling storage of liquids such as milk and juice, ensuring food safety and quality. In the pharmaceutical industry, they are used for reaction heat control, drug concentration, and cooling in drug production processes, meeting the stringent temperature control requirements of drug production and ensuring drug quality and production safety. Using compact heat exchangers, such as plate heat exchangers or spiral plate heat exchangers, allows for efficient heat transfer within a limited space, rapid temperature adjustment during extraction processes, meeting the stringent temperature requirements of supercritical fluid extraction, and reducing equipment footprint.

[0003] An existing patent (publication number: CN217900584U) describes a spiral heat exchanger. This heat exchanger uses fluid tubes A and B, which are designed with convex and concave shapes to accelerate heat transfer from the wall to the fluid body and enhance the heat transfer process. However, this heat exchanger does not have the ability to be quickly disassembled. When maintaining the equipment, cleaning, or replacing faulty parts, a lot of time needs to be spent disassembling the complex structure, which leads to prolonged downtime, increased maintenance costs, and frequent disassembly and assembly may damage precision flow channels or seals, reduce equipment reliability and service life, and affect continuous production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a compact heat exchanger, which effectively solves the problem that the existing heat exchangers do not have the ability to be quickly disassembled. When maintaining, cleaning or replacing faulty parts, a lot of time is required to disassemble the complex structure, which leads to prolonged downtime and increased maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A compact heat exchanger includes a support frame. A heat exchanger shell is fixedly installed on the upper part of the support frame. A sealing disc is provided on one side of the heat exchanger shell, and a sealing ring is provided between the sealing disc and the heat exchanger shell. A servo motor is fixedly installed on the upper part of one side of the heat exchanger shell via a connecting frame. Four docking rods are fixedly installed at equal intervals in a ring on the circumference of the sealing disc. Four docking sleeves are fixedly installed at equal intervals in a ring on one side of the surface of the heat exchanger shell. The four docking rods are inserted into the four docking sleeves, and one end of each of the four docking rods has an opening. A roller is rotatably installed on one side inside each opening. A pushing block is inserted inside the opening, and the inclined surfaces of the four pushing blocks are respectively in close contact with the four rollers. A transmission component is provided at the output end of the servo motor. The transmission component is connected to the four pushing blocks. When the servo motor is running, it outputs power to the four pushing blocks through the transmission component. Several corrugated plates are installed inside the heat exchanger shell. Corrugated grooves are provided on both sides of the corrugated plates. The corrugated grooves on two adjacent corrugated plates are spliced ​​to form a spiral water channel.

[0006] Preferably, the transmission assembly includes a gear, which is fixedly installed at the output end of the servo motor. A positioning frame is rotatably installed on one side of the gear, and one end of the positioning frame is fixedly connected to the connecting frame. An external gear ring is meshed with the lower part of the gear, and a rotating sleeve is fixedly installed inside the external gear ring. The rotating sleeve is rotatably installed on the other side of the heat exchanger shell surface.

[0007] Preferably, a plurality of support rods are fixedly installed at equal intervals on the circumference of the rotating sleeve, and a transmission ring is fixedly installed between one end of the plurality of support rods. Four transmission blocks are fixedly installed at equal intervals on the inner wall of the transmission ring. A contact head is tightly attached to one side of each transmission block, a pressure plate is fixedly installed on one side of each contact head, and an insertion rod is fixedly installed on one side of each pressure plate. The end of the insertion rod away from the pressure plate is fixedly connected to the corresponding pushing block.

[0008] Preferably, one end of each insertion rod is fitted with a sleeve, the surface of which is fixedly connected to the heat exchanger shell via a support base, and the other end of each insertion rod is fitted with a spring, the two ends of which are fixedly connected to the pressure plate and the sleeve, respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In operation, the spiral water channel formed by splicing the corrugated grooves on the corrugated plate can achieve efficient heat exchange; and the heat exchanger shell adopts a vertical circular design, making the whole device more compact and greatly reducing the floor space; during disassembly, the operator starts the servo motor to drive the gear to rotate along the positioning frame. When the gear rotates, it drives the rotating sleeve to rotate through the external gear ring. When the rotating sleeve rotates, it drives the transmission ring to rotate through several support rods. When the transmission ring rotates, it drives the four transmission blocks away from the four contact heads, thereby relieving the compression on the four contact heads.

[0010] After the pressure on the contact head is released, the springs push the pressure plate to move through their own elastic force. The pressure plate drives the insertion rod to slide along the inside of the insertion sleeve, thereby driving the push block to exit the opening. This releases the pressure limit on the roller, allowing the docking rod to be pulled out of the docking sleeve, thus quickly removing the sealing plate and cleaning the inside of the device. This gives the heat exchanger a quick disassembly capability, making it very convenient for equipment maintenance, cleaning, or replacement of faulty parts, reducing downtime and maintenance costs.

Four docking rods 6 are fixedly mounted at equal intervals in a ring on the circumference of the sealing plate 3. Four docking sleeves 7 are fixedly mounted at equal intervals in a ring on one side of the surface of the heat exchanger shell 2. The four docking rods 6 are inserted into the four docking sleeves 7, and one end of each of the four docking rods 6 is opened. A roller 9 is rotatably installed on one side inside the opening 8. A push block 10 is inserted inside the opening 8, and the inclined surfaces of the four push blocks 10 are respectively in close contact with the four rollers 9. The output end of the servo motor 5 is provided with a transmission component, which is connected to the four push blocks 10. When the servo motor 5 is running, it outputs power to the four push blocks 10 through the transmission component. Several corrugated plates 23 are installed inside the heat exchanger shell 2. Corrugated grooves 24 are opened on both sides of the corrugated plates 23. The corrugated grooves 24 on two adjacent corrugated plates 23 are spliced ​​to form a spiral water channel.

[0022] During operation, the spiral water channel formed by the corrugated grooves 24 on the corrugated plate 23 can achieve efficient heat exchange; and the heat exchanger shell 2 adopts a vertical circular design, making the whole device more compact and greatly reducing the floor space. When disassembling, the operator starts the servo motor 5 to drive the transmission component to operate. When the transmission component operates, it drives the push block 10 out of the opening 8, thereby releasing the compression limit on the roller 9, so that the docking rod 6 can be pulled out from the docking sleeve 7, thereby quickly removing the sealing disc 3, and then cleaning the inside of the device. This gives the heat exchanger the ability to be quickly disassembled, which is very convenient for equipment maintenance, cleaning or replacement of faulty parts, reducing downtime and maintenance costs.

[0023] The transmission assembly includes a gear 11, which is fixedly installed at the output end of the servo motor 5. A positioning frame 12 is rotatably installed on one side of the gear 11. One end of the positioning frame 12 is fixedly connected to the connecting frame 4. An external gear ring 25 is meshed with the lower part of the gear 11. A rotating sleeve 14 is fixedly installed inside the external gear ring 25. The rotating sleeve 14 is rotatably installed on the other side of the surface of the heat exchanger housing 2.

[0024] During disassembly, the operator starts the servo motor 5 to drive the gear 11 to rotate along the positioning frame 12. When the gear 11 rotates, it drives the rotating sleeve 14 to rotate through the external gear ring 25.

[0025] A plurality of support rods 13 are fixedly installed at equal intervals on the circumference of the rotating sleeve 14. A transmission ring 15 is fixedly installed between one end of the plurality of support rods 13. Four transmission blocks 16 are fixedly installed at equal intervals on the inner wall of the transmission ring 15. A contact head 17 is tightly attached to one side of each transmission block 16. A pressure plate 18 is fixedly installed on one side of each contact head 17. An insertion rod 19 is fixedly installed on one side of each pressure plate 18.

The surface of the insertion sleeve 20 is fixedly connected to the heat exchanger shell 2 through a support seat 22. A spring 21 is fitted on the other end of the surface of each insertion rod 19. Both ends of the spring 21 are fixedly connected to the pressure plate 18 and the insertion sleeve 20, respectively.

[0026] When the rotating sleeve 14 rotates, it drives the transmission ring 15 to rotate through several support rods 13. When the transmission ring 15 rotates, it drives the four transmission blocks 16 away from the four contact heads 17, thereby releasing the compression of the four contact heads 17. After the compression of the contact heads 17 is released, the springs 21 push the pressure plate 18 to move through their own elastic force. The pressure plate 18 drives the insertion rod 19 to slide along the inside of the insertion sleeve 20, thereby driving the pushing block 10 to exit the inside of the opening 8, and thus releasing the compression limit on the roller 9.
