Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat exchangers, in particular to a heat exchange device based on alloy conversion tube finishing. BACKGROUND

[0002] In the finishing process of alloy tubes, stainless steel tubes and other metal materials, the tubular heat exchanger is the key equipment for controlling the temperature of the cooling liquid, and its heat exchange efficiency directly affects the machining precision of the workpiece and the service life of the tool. However, the existing tubular heat exchanger has significant defects in actual application, and it is difficult to meet the needs of high-precision and high-load machining scenarios.

[0003] In terms of heat exchange uniformity, in the tube side of the traditional tubular heat exchanger, the flow state of the cooling liquid is single, and temperature stratification phenomenon is easy to occur. The high-temperature fluid is concentrated in the central area of the pipe and cannot fully contact the pipe wall, resulting in low heat exchange efficiency. Taking high-speed grinding of titanium alloy pipe as an example, the temperature of the hot liquid can rise above 60℃ in a short time, and the heat exchange coefficient of the traditional equipment is usually less than 1200W / (m 2 ・K), which is difficult to effectively control the temperature of the cooling liquid in the ideal interval below 35℃, thereby causing thermal deformation of the workpiece and affecting the machining precision.

[0004] In terms of anti-fouling performance, metal chips, grease and impurities in the cooling liquid generated during metal processing are easy to adhere to the inner wall of the heat exchange tube to form an insulating layer. Related research shows that when the thickness of the pipe wall fouling reaches 0.3mm, the thermal resistance will increase by more than 40%, resulting in a decrease of about 25% in heat exchange efficiency. The current common solution is to regularly stop production for manual cleaning, but this not only consumes a lot of time and labor cost, but also may cause damage to the sealing elements of the equipment and reduce the service life of the equipment.

[0005] In terms of temperature control flexibility, the existing heat exchanger adopts a fixed flow cooling mode and lacks dynamic response capability to changes in the temperature of the hot liquid. When the machining condition changes, such as switching from rough machining to finishing, the temperature of the hot liquid will fluctuate greatly. If the flow and speed of the hot liquid cannot be adjusted in time, it may lead to insufficient cooling or excessive cooling, affecting the machining quality and production efficiency.

[0006] In summary, the existing tubular heat exchanger has obvious shortcomings in heat exchange uniformity, anti-fouling ability and temperature control flexibility, and it is difficult to meet the requirements of precise control of the temperature of the cooling liquid in the finishing process of metal tubes. Therefore, there is an urgent need for a new tubular heat exchanger that can realize efficient and uniform heat exchange, automatic anti-fouling and intelligent temperature control adjustment, in order to improve the overall technical level of the metal processing industry.

[0033] Further, the flow adjusting device comprises a baffle 31, the baffle 31 is provided with a counter-punch block 32 at the right side, the left sidewall of the baffle 31 is fixedly connected to a connecting rope 33, the left end of the connecting rope 33 is fixedly connected to a permanent magnet 34, the sidewall of the permanent magnet 34 is fixedly connected to two symmetrical second sliding pieces 35, two symmetrical second sliding grooves 36 are formed in the inner wall of the hot liquid inlet pipe 4, and a heat-sensitive magnet 37 is fixedly connected to the inner wall of the hot liquid inlet pipe 4, thereby keeping the baffle 31 in a vertical state under the action of the counter-punch block 32 when being impacted by the hot liquid.

[0034] Further, the baffle 31 is hinged to the inner wall of the hot liquid inlet pipe 4, the counter-punch block 32 is fixedly connected to the inner wall of the hot liquid inlet pipe 4, one end of the second sliding piece 35 away from the permanent magnet 34 is arranged in and slides in the second sliding groove 36, and the heat-sensitive magnet 37 is located at the left side of the permanent magnet 34, thereby the attractive force between the heat-sensitive magnet 37 and the permanent magnet 34 can change the state of the baffle 31.

[0035] Further, the width of the baffle 31 is half of the hot liquid inlet pipe 4, the permanent magnet 34 and the heat-sensitive magnet 37 are magnetically different, and the minimum water inlet amount of the hot liquid inlet pipe 4 is greater than the sum of the water inlet amounts of the heat exchange pipes 8 below the baffle 24, thereby the flow rate in the heat exchange pipes 8 can be changed when the hot liquid inlet amount changes.

[0036] Working principle: when using the device, the cooling liquid for finishing alloy pipe is heated and enters through the hot liquid inlet pipe 4, fills the space below the baffle 24, and enters the heat exchange pipe 8 below the baffle 24. The cooling water enters the tube shell 1 through the cold liquid inlet pipe 6. The hot liquid and the cooling water exchange heat. At the same time, the external power supply is connected, the motor 27 is turned on, the motor 27 drives the rotating shaft 26 to rotate, the rotating shaft 26 drives the rotating disc 23 to rotate, the rotating disc 23 drives the concentric gear ring 25 to rotate, the concentric gear ring 25 drives the gear 11 meshing therewith to rotate, the gear 11 drives the reciprocating screw 10 fixedly connected thereto to rotate. Due to the restriction of the first sliding vane 14, the translation ring 12 moves horizontally along the reciprocating screw 10 under the drive of the reciprocating screw 10, the rotating ring 17 rotates under the drive of the reciprocating screw 10 and is connected with the translation ring 12 through the connecting ring 15, moves horizontally along the reciprocating screw 10 synchronously under the action of the translation ring 12, drives the supporting plate 18 and the scraping block 19 to move horizontally in the heat exchange pipe 8 while rotating, thereby stirring the hot liquid in the heat exchange pipe 8 while the scraping block 19 scrapes the inner wall of the heat exchange pipe 8. Not only can the hot liquid in the heat exchange pipe 8 and the external cooling water exchange heat more effectively, but also the impurities attached to the inner wall of the heat exchange pipe 8 due to the flow of the hot liquid can be scraped off, thereby avoiding the formation of a heat insulation layer. The scraped impurities are retained with the hot liquid flowing through the filter plate 22, the filter plate 22 can be removed for cleaning. When the temperature of the hot liquid entering through the hot liquid inlet pipe 4 is too high, on the one hand, the thermosensitive magnet 37 loses magnetism and no longer has an attractive force to the permanent magnet 34. The baffle 31 moves downward on the left side under the action of gravity and finally presents a vertical state under the action of gravity, the impact of the hot liquid and the resistance of the counterblock 32, thereby reducing the amount of hot liquid entering and the water pressure in the heat exchange pipe 8, reducing the flow rate of the hot liquid in the heat exchange pipe 8 and making the heat exchange more sufficient. On the other hand, when the temperature of the entering hot liquid increases, the resistance of the thermistor 30 decreases, the current in the circuit increases, the rotating speed of the rotating shaft 26 increases, and the rotating speed of the supporting plate 18 and the scraping block 19 increases, thereby more fully stirring the hot liquid in the heat exchange pipe 8, increasing the heat exchange efficiency, more effectively reducing the temperature of the hot liquid, and making the hot liquid after heat exchange flow out through the cold liquid inlet pipe 6 for reuse.

[0037] The above description enables those skilled in the art to implement or use the present application, and various modifications to these embodiments will be apparent 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 application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
