Description

Technical Field

[0001] The present invention relates to the field of heat exchangers, and specifically to a heat exchange device based on the finish machining of high-strength alloy conversion tubes. Background Art

[0002] In the finish machining process of metal materials such as alloy tubes and stainless steel tubes, the shell-and-tube heat exchanger is a key device for controlling the temperature of the coolant. Its heat exchange efficiency directly affects the machining accuracy of workpieces and the service life of cutting tools. However, the existing shell-and-tube heat exchangers have significant defects in actual applications and are difficult to meet the requirements of high-precision and high-load machining scenarios.

[0003] In terms of heat exchange uniformity, within the tube pass of the traditional shell-and-tube heat exchanger, the flow state of the coolant to be processed is single, and temperature stratification is likely to occur. The high-temperature fluid is concentrated in the central area of the pipeline and cannot come into full contact with the pipe wall, resulting in low heat exchange efficiency. Taking the high-speed grinding of titanium alloy tubes as an example, the temperature of the hot fluid can rise above 60°C within a short time, while the traditional equipment only relies on natural convection heat transfer, and the heat transfer coefficient is usually lower than 1200 W / (m²・K), making it difficult to effectively control the temperature of the coolant within the ideal range below 35°C, thereby causing thermal deformation of the workpiece and affecting the machining accuracy.

[0004] In terms of anti-scaling performance, metal chips, grease, and impurities in the coolant generated during the metal processing process are extremely likely to adhere to the inner wall of the heat exchange tube to form a heat insulation layer. Relevant research shows that when the scaling thickness of the pipe wall reaches 0.3 mm, the thermal resistance will increase by more than 40%, resulting in a decrease in heat exchange efficiency of about 25%. The currently common solution is to stop the machine regularly for manual cleaning, but this not only consumes a large amount of time and labor costs, but also frequent disassembly may cause damage to the equipment seals and reduce the service life of the equipment.

[0005] In terms of temperature control flexibility, most of the existing heat exchangers adopt a fixed-flow cooling mode and lack the dynamic response ability to changes in the temperature of the hot fluid. When the processing conditions change, such as switching from rough machining to finish machining, the temperature of the hot fluid will fluctuate greatly. If the flow rate and velocity of the hot fluid cannot be adjusted in time, it may lead to insufficient cooling or over-cooling, affecting the machining quality and production efficiency.

[0006] In summary, the existing shell-and-tube heat exchangers have obvious deficiencies in heat exchange uniformity, anti-scaling ability, and temperature control flexibility, and are difficult to meet the requirements of precise control of the coolant temperature for the finish machining of metal tubes. Therefore, there is an urgent need for a new type of shell-and-tube heat exchanger that can achieve efficient and uniform heat exchange, automatic anti-scaling, and intelligent temperature control adjustment to improve the overall technical level of the metal processing industry.

[0011] Preferably, the rotation adjustment device includes a turntable. A plurality of concentric tooth rings are fixedly connected to the left end of the turntable. A rotating shaft is fixedly connected to the center of the left end of the turntable. A motor is fixedly installed at the left end of the rotating shaft.

[0016] The present invention provides a heat exchange device based on the finish machining of high-strength alloy conversion pipes. Compared with the prior art, it has the following improvements and advantages: 1. In the present invention, by arranging a reciprocating screw in the heat exchange pipe and movably connecting a scraping block to the outer surface of the reciprocating screw, the scraping block has the dual functions of scraping the pipe wall back and forth in a straight line and rotating and stirring the hot liquid. The linear motion can effectively remove grease and impurities on the pipe wall and prevent the formation of a heat insulation layer. The rotational motion promotes the uniform contact of the coolant in the pipe with the pipe wall, accelerating heat transfer. Compared with the traditional shell-and-tube heat exchanger, the heat exchange efficiency is significantly improved. 2. The present invention is provided with a rotation adjustment device. The thermistor in the device can monitor the temperature of the hot liquid in real time and convert the temperature signal into an electrical signal and feedback it to the motor control system. When the temperature of the hot liquid rises, the resistance value of the thermistor decreases, and the motor speed automatically increases accordingly, thereby accelerating the rotation and stirring of the scraping block and the frequency of the linear wall scraping movement. This mechanism can dynamically enhance the uniformity of the hot liquid mixing and the cleaning strength of the pipe wall, avoiding the decrease in heat exchange efficiency caused by the increase in heat load. 3. In the present invention, by setting a flow rate adjustment device, the flow rate adjustment device in the hot liquid inlet pipe adopts a heat-sensitive magnet with Curie temperature characteristics. When the temperature of the hot liquid is lower than the critical value, the heat-sensitive magnet and the permanent magnet attract each other due to different magnetic properties. The permanent magnet pulls the baffle through a connecting rope, keeping the hot liquid inlet pipe with a larger diameter to ensure the rapid inflow of the hot liquid. When the temperature of the hot liquid exceeds the Curie temperature of the heat-sensitive magnet, the heat-sensitive magnet instantly loses its magnetism, and the attraction force on the permanent magnet disappears. Under the action of the self-pressure of the hot liquid and the reset structure, the baffle automatically rotates to reduce the diameter of the hot liquid inlet, lower the flow rate of the hot liquid, extend its residence time in the pipe, and fully improve the heat exchange effect. When the temperature of the hot liquid drops below the Curie temperature, the heat-sensitive magnet resumes its magnetism, and the diameter of the inlet pipe returns to normal again.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides a heat exchange device based on the finish machining of a high-strength alloy conversion tube. The technical solution of the present invention is as follows: As Figure 1 - Figure 5 shown, the heat exchange device based on the finish machining of a high-strength alloy conversion tube includes a tube shell 1.

A hot liquid inlet pipe 4 is fixedly installed below the outer surface of the tube shell 1. A hot liquid outlet pipe 5 is fixedly installed above the outer surface of the tube shell 1. A cold liquid inlet pipe 6 is fixedly installed above the outer surface of the tube shell 1. A cold liquid outlet pipe 7 is fixedly installed below the outer surface of the tube shell 1. A plurality of identical heat exchange tubes 8 are arranged in the inner cavity of the tube shell 1. Fixed plates 9 are fixedly connected to the outer surfaces of both ends of the heat exchange tubes 8. A reciprocating screw 10 is arranged in the inner cavity of each heat exchange tube 8. A gear 11 is fixedly connected to the outer surface of the left end of each reciprocating screw 10. A translation ring 12 is threadedly connected to the outer surface of each reciprocating screw 10. A rotating groove 13 is arranged at the left end of each translation ring 12. Two symmetric first sliding plates 14 are fixedly connected to the outer surface of each translation ring 12. A connecting ring 15 is threadedly connected to the outer surface of each reciprocating screw 10. Two symmetric fixing blocks 16 are fixedly connected to the outer surface of each connecting ring 15. A rotating ring 17 is fixedly connected to the left end of each connecting ring 15. A plurality of support plates 18 are fixedly connected to the outer surface of each rotating ring 17. A scraping block 19 is fixedly connected to the upper surface of each support plate 18. Two symmetric first sliding grooves 20 are formed in the inner wall of each heat exchange tube 8. A plurality of identical baffle plates 21 are fixedly connected to the outer surface of the heat exchange tubes 8. A filter plate 22 is fixedly connected to the right end of the heat exchange tubes 8 located in the lower half. The outer surfaces of the left ends of the plurality of reciprocating screws 10 are rotatably connected to the same turntable 23. A partition plate 24 is arranged between the left fixed plate 9 and the turntable 23. A rotation adjusting device is arranged at the left end of the turntable 23. A flow rate adjusting device is arranged in the inner cavity of the hot liquid inlet pipe 4.

[0021] Furthermore, the hot liquid inlet pipe 4 and the hot liquid outlet pipe 5 are arranged between the fixed plate 9 and the turntable 23. The cold liquid inlet pipe 6 is arranged between the fixed plate 9 and the leftmost baffle plate 21. The cold liquid outlet pipe 7 is arranged between the right fixed plate 9 and the rightmost baffle plate 21, so as to extend the path of the cooling water in the tube shell 1 and increase the heat exchange time.

[0022] Furthermore, the right end of the reciprocating screw 10 is arranged on the inner wall of the shell cover 2 and is rotatably connected to the shell cover 2. The connecting ring 15 and the fixing block 16 are both arranged in the rotating groove 13. The connecting ring 15 and the fixing block 16 are both rotatably connected to the translation ring 12. The first sliding piece 14 is arranged in the first sliding groove 20 and can slide in the first sliding groove 20. Thus, under the action of the translation ring 12 and the reciprocating screw 10, the support plate 18 and the scraping block 19 can move and rotate.

[0023] Furthermore, the rotation adjusting device includes a turntable 23. A plurality of concentric toothed rings 25 are fixedly connected to the left end of the turntable 23. The center of the left end of the turntable 23 is fixedly connected to a rotating shaft 26. A motor 27 is fixedly installed at the left end of the rotating shaft 26. A wire 28 is fixedly connected to the left end of the motor 27. A support column 29 is fixedly installed on the outer surface of the motor 27. A thermistor 30 is fixedly connected to the left end of the turntable 23. A wire 28 is fixedly connected to the side wall of the thermistor 30. Thus, the rotation speed of the support plate 18 and the scraping block 19 can be controlled by affecting the thermistor 30.

[0024] Furthermore, the outer edge of the gear 11 meshes with the corresponding toothed ring 25. The thermistor 30 penetrates through the turntable 23, and the right side wall of the thermistor 30 is located between the fixing plate 9 and the turntable 23. The motor 27 and the thermistor 30 are both electrically connected to an external power supply through the wire 28. The higher the temperature, the smaller the resistance value of the thermistor 30. Thus, the hot liquid entering the shell 1 can affect the resistance value of the thermistor 30.

[0025] Furthermore, the flow rate adjusting device includes a baffle 31. A counterflush block 32 is arranged on the right side of the baffle 31. A connecting rope 33 is fixedly connected to the left side wall of the baffle 31. A permanent magnet 34 is fixedly connected to the left end of the connecting rope 33. Two symmetric second sliding pieces 35 are fixedly connected to the side wall of the permanent magnet 34. Two symmetric second sliding grooves 36 are formed in the inner wall of the hot liquid inlet pipe 4. A heat-sensitive magnet 37 is fixedly connected to the inner wall of the hot liquid inlet pipe 4. Thus, when impacted by the hot liquid, the baffle 31 can maintain a vertical state under the action of the counterflush block 32.

[0026] Furthermore, the baffle 31 is hinged to the inner wall of the hot liquid inlet pipe 4. The counterflush block 32 is fixedly connected to the inner wall of the hot liquid inlet pipe 4. The end of the second sliding piece 35 away from the permanent magnet 34 is arranged in the second sliding groove 36 and can slide in the second sliding groove 36. The heat-sensitive magnet 37 is located on the left side of the permanent magnet 34. Thus, the attraction force between the heat-sensitive magnet 37 and the permanent magnet 34 can change the state of the baffle 31.

[0027] Further, the width of the baffle 31 is half of that of the hot liquid inlet pipe 4, the permanent magnet 34 and the heat-sensitive magnet 37 have different magnetic polarities, and the minimum water inflow of the hot liquid inlet pipe 4 is greater than the sum of the water inflows of the heat exchange pipes 8 located below the partition plate 24. Thus, when the hot liquid inflow changes, the flow rate in the heat exchange pipes 8 can be changed.

[0028] Working principle: When using this device, the coolant for precision machining of alloy pipes enters through the hot liquid inlet pipe 4 after getting heated, fills the space below the partition plate 24, and enters the heat exchange pipes 8 located below the partition plate 24. The cooling water enters through the cold liquid inlet pipe 6 and fills the shell 1. While the hot liquid exchanges heat with the cooling water, the external power supply is connected and the motor 27 is turned on. The motor 27 drives the rotating shaft 26 to rotate, the rotating shaft 26 drives the turntable 23 to rotate, the turntable 23 drives the concentric gear ring 25 to rotate, the concentric gear ring 25 drives the engaged gear 11 to rotate, and the gear 11 drives the reciprocating screw 10 fixedly connected thereto to rotate. Due to the restriction of the first sliding piece 14, the translation ring 12 moves horizontally along the reciprocating screw 10 driven by the reciprocating screw 10. The rotating ring 17 rotates driven by the reciprocating screw 10 and is connected to the translation ring 12 through the connecting ring 15, and synchronously moves horizontally along the reciprocating screw 10 under the action of the translation ring 12, driving the support plate 18 and the scraping block 19 to rotate while moving horizontally in the heat exchange pipes 8. Thus, while stirring the hot liquid in the heat exchange pipes 8, the scraping block 19 scrapes the inner wall of the heat exchange pipes 8. This can not only enable the hot liquid in the heat exchange pipes 8 to exchange heat with the external cooling water more effectively, but also scrape off the impurities adhering to the inner wall of the heat exchange pipes 8 brought by the hot liquid, preventing the formation of a heat insulation layer. The scraped impurities are retained as the hot liquid flows through the filter plate 22, and the filter plate 22 can be removed for cleaning. When the temperature of the hot liquid entering through the hot liquid inlet pipe 4 becomes higher and exceeds the normal value, on the one hand, the heat-sensitive magnet 37 loses its magnetism and no longer attracts the permanent magnet 34. Under the action of its own weight, the left side of the baffle 31 moves downward, and finally assumes a vertical state under the action of gravity, hot liquid impact and the blockage of the impact block 32, reducing the hot liquid inflow, thereby reducing the water pressure in the heat exchange pipes 8 and lowering the flow rate of the hot liquid in the heat exchange pipes 8, making the heat exchange more sufficient. On the other hand, when the temperature of the entering hot liquid rises, the resistance of the thermistor 30 decreases, the current in the circuit increases, the rotation speed of the rotating shaft 26 increases, and thus the rotation speed of the support plate 18 and the scraping block 19 increases, stirring the hot liquid in the heat exchange pipes 8 more fully, increasing the heat exchange efficiency, and more effectively reducing the temperature of the hot liquid. The hot liquid after heat exchange flows out through the cold liquid inlet pipe 6 and is reused.

[0029] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
