Description

Technical Field

[0001] This invention relates to the field of evaporator technology, and more specifically, to a cold box evaporator with a temperature detection unit. Background Technology

[0002] As the core heat exchange component of refrigeration and freezing equipment, the evaporator of a cold box directly determines the performance of the cold box through its refrigeration efficiency and operational stability. The liquid receiver pipe, as the key structure for the collection and distribution of refrigerant in the evaporator, has its temperature parameters as the core indicators reflecting the phase change of the refrigerant and the heat exchange efficiency. Therefore, accurate temperature detection of the liquid receiver pipe has become a necessary means for the control and protection of the cold box refrigeration system. In existing technologies, cold box evaporators typically have a temperature sensing element, such as an NTC thermistor or thermocouple, fixed on the outer wall of the liquid storage tube. Temperature is collected through direct thermal contact between the sensing element and the surface of the liquid storage tube. However, in practical applications, dust and impurities carried by airflow gradually adhere to the surface of the temperature sensing area of ​​the liquid storage tube. Over time, an uneven dust layer forms on the surface of the liquid storage tube. This dust layer, acting as a thermal insulation medium, hinders the heat transfer efficiency between the temperature sensing element and the liquid storage tube, causing the sensing element to fail to capture the true temperature of the liquid storage tube in real time, resulting in inaccurate temperature measurement data. Summary of the Invention

[0008] Preferably, the buffer assembly includes two buffer rods fixedly installed on the upper surface of the disassembly plate and with their upper ends penetrating through the lifting plate. A buffer ring is fixedly installed at the penetrating end of the buffer rod. Each buffer rod located between the disassembly plate and the lifting plate is fitted with a first spring, which is used to push the disassembly plate away from the lifting plate.

[0009] Preferably, a locking block is fixedly installed on the side wall of the temperature probe facing the motor, and a vertical plate is fixedly installed on the lower end face of the disassembly plate. A protrusion with one end inserted into the locking block is fixedly installed on the side wall of the vertical plate facing the locking block.

[0010] Preferably, a retaining ring is fixedly installed on the side wall of the temperature probe away from the card block; The disassembly and assembly assembly includes a horizontal plate fixedly installed on the lower end face of the disassembly and assembly plate, a disassembly and assembly cylinder fixedly installed on the lower end face of the horizontal plate, a cavity opened inside the disassembly and assembly cylinder, an insert plate placed inside the cavity, an insert rod fixedly installed on the side wall of the insert plate facing the insert ring, and a second spring for driving the insert plate to move towards the insert ring placed inside the cavity.

[0011] Preferably, opposing supports are fixedly installed on the upper end face of the mounting box, and opposing sliding rods that penetrate the sliding plate are fixedly installed between the two supports; The movable component includes a mounting base fixedly mounted on the upper surface of the mounting box, and an electric push rod fixedly mounted on the upper surface of the mounting base.

[0014] 3. This invention, through the elastic buffer design of the buffer component, can convert the rigid driving force transmitted by the lifting plate into a flexible elastic thrust when the temperature probe comes into contact with the liquid storage tube. This effectively avoids hard collisions and squeezing between the probe and the wall of the liquid storage tube, preventing the temperature probe from being damaged, deformed, or having its detection accuracy compromised due to rigid contact. It provides all-round protection for the temperature probe, extends its service life, and reduces the frequency of replacement of vulnerable parts and maintenance costs.

[0023] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0024] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0025] A cold box evaporator with a temperature detection unit in this embodiment includes a base plate 12, an evaporator 10 is fixedly installed on the upper end surface of the base plate 12, an mounting plate is fixedly installed on the upper end surface of the base plate 12, a lifting plate 14 is provided above the mounting plate, and opposing lifting blocks 19 are fixedly installed on the side wall of the lifting plate 14 away from the evaporator 10. The upper end surface of the mounting plate is provided with a lifting assembly for driving the lifting plate 14 to rise and fall. A disassembly plate 15 is provided below the lifting plate 14, and a buffer assembly for buffering is provided between the upper end face of the disassembly plate 15 and the lower end face of the lifting plate 14. A temperature probe 16 is provided below the disassembly plate 15, and a disassembly assembly for attaching and detaching the temperature probe 16 is provided on the lower end face of the disassembly plate 15. A mounting box 13 is fixedly mounted on the upper end face of the mounting plate. A sliding plate 26 is slidably mounted on the upper end face of the mounting box 13. A support rod 27 is provided on the upper end face of the sliding plate 26. A support block 28 is fixedly mounted on the support rod 27 toward the side wall of the evaporator 10. A brush 29 is fixedly mounted on the support block 28 toward the side wall of the evaporator 10. A moving component for driving the sliding plate 26 to reciprocate is provided on the upper end face of the mounting box 13.

[0026] In this embodiment, when it is necessary to detect the temperature of the liquid storage tube 11 of the evaporator 10, the sliding plate 26 is driven to reciprocate by the moving component on the mounting box 13. The movement of the sliding plate 26 drives the support block 28 to reciprocate via the support rod 27. The reciprocating movement of the support block 28 drives the brush 29 to reciprocate above the liquid storage tube 11. The movement of the brush 29 can wipe the surface of the liquid storage tube 11 and clean the dust in specific locations on the surface of the liquid storage tube 11. After the brush 29 has finished cleaning the liquid storage tube 11, the lifting component on the mounting plate drives the two lifting blocks 19 to rise and fall. The two lifting blocks 19 can rise and fall. The lifting plate 14 can be raised and lowered. When the lifting plate 14 moves down, it can drive the disassembly plate 15 to move down. The disassembly plate 15 moves down and drives the temperature probe 16 to move down, so that the temperature probe 16 comes into contact with the cleaned position of the liquid storage tube 11. At this time, the temperature probe 16 can detect the temperature of the surface of the liquid storage tube 11. After the temperature probe 16 completes the temperature detection of the liquid storage tube 11, the lifting assembly drives the lifting plate 14 to move up. The upward movement of the lifting plate 14 is carried by the disassembly plate 15, so that the temperature probe 16 below the disassembly plate 15 moves away from the liquid storage tube 11, thereby releasing the temperature detection of the liquid storage tube 11 by the temperature probe 16. When the lifting plate 14 drives the temperature probe 16 to abut against the liquid storage tube 11 through the disassembly plate 15, the buffer assembly between the disassembly plate 15 and the lifting plate 14 can buffer the contact between the temperature probe 16 and the liquid storage tube 11, thereby avoiding hard contact between the temperature probe 16 and the liquid storage tube 11, which would cause damage to the temperature probe 16. When the temperature probe 16 is used for a long time, the temperature probe 16 may be damaged and needs to be repaired. The temperature probe 16 can be removed from the installation under the disassembly plate 15 by the disassembly assembly to repair the damaged temperature probe 16. After the temperature probe 16 has been repaired, the temperature probe 16 can be installed under the disassembly plate 15 by the disassembly assembly. In this process, the sliding plate 26 is driven to reciprocate by the moving component, so that the brush 29 cleans the dust on the surface of the liquid storage tube 11. Compared with the existing structure, this cold box evaporator with a temperature detection unit can avoid the dust on the surface of the liquid storage tube 11 from affecting the contact between the temperature probe 16 and the liquid storage tube 11 in actual use, thereby ensuring the accuracy and stability of the temperature probe 16 in detecting the temperature of the liquid storage tube 11.

[0027] In this embodiment, an installation cavity is provided inside the installation box 13; The lifting assembly includes two threaded rods 17 rotatably mounted in the mounting cavity. The upper ends of the two threaded rods 17 extend out of the mounting box 13, and the protruding ends of the threaded rods 17 threadedly pass through the corresponding lifting blocks 19.

[0028] In this embodiment, the lower end of the threaded rod 17 is rotatably mounted on the lower side of the mounting cavity via a bearing. When the two threaded rods 17 rotate synchronously, the two threaded rods 17 can drive the lifting plate 14 to move up and down via the two lifting blocks 19. Each threaded rod 17 located in the mounting cavity is fixedly fitted with a synchronous pulley 42, and a synchronous belt 43 is fitted between the two synchronous pulleys 42. The upper end face of the mounting box 13 is provided with a driving component for driving one of the two threaded rods 17 to rotate. When the driving component drives one of the threaded rods 17 to rotate, the threaded rod 17 can drive the synchronous pulley 42 to rotate. The rotation of the synchronous pulley 42 can drive the synchronous pulley 42 on the other threaded rod 17 to rotate through the synchronous belt 43, that is, the other threaded rod 17 rotates, so that the two threaded rods 17 rotate synchronously. The upper end of the mounting plate is fixedly mounted with opposing and bent limiting frames 18. The upper end of the threaded rod 17 is connected to the upper end of the corresponding limiting frame 18 through a bearing, so that the two limiting frames 18 limit the upper ends of the two threaded rods 17, allowing the threaded rods 17 to rotate stably.

[0029] In this embodiment, a first gear 44 is fixedly sleeved on one of the threaded rods 17 located in the mounting cavity; The driving component includes a motor 30 fixedly mounted on the upper end face of the mounting box 13. The output shaft of the motor 30 extends into the mounting cavity. The output shaft of the motor 30 located in the mounting cavity is fixedly sleeved with a second gear 45 that meshes with the first gear 44.

[0030] In this embodiment, when the motor 30 drives the second gear 45 to rotate in the mounting cavity, the second gear 45 can drive the first gear 44 to rotate, that is, the first gear 44 drives one of its threaded rods 17 to rotate.

[0031] In this embodiment, the buffer assembly includes two buffer rods 20 that are fixedly installed on the upper surface of the disassembly plate 15 and have their upper ends penetrating through the lifting plate 14. A buffer ring 22 is fixedly installed at the penetrating end of the buffer rod 20. Each buffer rod 20 located between the disassembly plate 15 and the lifting plate 14 is fitted with a first spring 21. The first spring 21 is used to push the disassembly plate 15 away from the lifting plate 14.

[0032] In this embodiment, the buffer rod 20 on the upper surface of the disassembly plate 15 passes through the lifting plate 14. The end of the buffer rod 20 is fixed with a buffer ring 22, which can intercept and limit the lifting plate 14, thereby realizing the movable connection between the disassembly plate 15 and the lifting plate 14. When the lifting plate 14 moves down and drives the disassembly plate 15 to move down, so that the temperature probe 16 below the disassembly plate 15 abuts against the liquid storage tube 11, the lifting plate 14 can continue to move down. Its downward stroke is transmitted through the first spring 21 and drives the disassembly plate 15. At this time, the first spring 21 plays a buffering role, thereby effectively avoiding hard contact between the temperature probe 16 and the liquid storage tube 11.

[0033] In this embodiment, a locking block 34 is fixedly installed on the side wall of the temperature probe 16 facing the motor 30, and a vertical plate 31 is fixedly installed on the lower end face of the disassembly plate 15. A protrusion 33 with one end inserted into the locking block 34 is fixedly installed on the side wall of the vertical plate 31 facing the locking block 34.

[0034] In this embodiment, the temperature probe 16 is pre-installed under the disassembly plate 15 by placing the temperature probe 16 below the disassembly plate 15 and inserting the protrusion 33 on the side wall of the vertical plate 31 into the locking block 34.

[0035] In this embodiment, a retaining ring 36 is fixedly installed on the side wall of the temperature probe 16 away from the card block 34; The disassembly and assembly assembly includes a horizontal plate 35 fixedly installed on the lower end face of the disassembly and assembly plate 15. A disassembly and assembly cylinder 32 is fixedly installed on the lower end face of the horizontal plate 35. A cavity is opened inside the disassembly and assembly cylinder 32. An insert plate 38 is placed inside the cavity. An insert rod 39 is fixedly installed on the side wall of the insert plate 38 facing the insert ring 36. A second spring 40 for driving the insert plate 38 to move towards the insert ring 36 is placed inside the cavity.

[0036] In this embodiment, after the temperature probe 16 is pre-installed below the disassembly plate 15, the second spring 40 in the cavity drives the insertion plate 38 to move towards the insertion ring 36, so that the insertion rod 39 on the insertion plate 38 is inserted into the insertion ring 36. At this time, the installation of the temperature probe 16 below the disassembly plate 15 is realized. A pull rod 41 with one end extending out of the disassembly cylinder 32 is fixedly installed on the side wall of the insert plate 38 away from the insert ring 36. A pull plate 37 is fixedly installed on the extended end of the pull rod 41. The pull rod 41 is moved by pulling the pull plate 37, so that the pull rod 41 drives the insert plate 38 away from the insert ring 36. When the insert rod 39 on the insert plate 38 slides out of the insert ring 36, the installation of the temperature probe 16 under the disassembly plate 15 can be released. At this time, the temperature probe 16 can be removed from under the disassembly plate 15 by sliding the temperature probe 16. When the temperature probe 16 is pre-installed under the disassembly plate 15, the pull rod 41 needs to be moved by the pull plate 37. The pull rod 41 drives the insertion rod 39 on the insertion plate 38 to be located in the cavity, thereby preventing the insertion rod 39 from protruding out of the cavity and thus affecting the pre-installation of the temperature probe 16 under the disassembly plate 15.

[0037] In this embodiment, opposing supports 23 are fixedly installed on the upper end face of the mounting box 13, and opposing sliding rods 24 that penetrate the sliding plate 26 are fixedly installed between the two supports 23. The movable component includes a mounting base fixedly mounted on the upper surface of the mounting box 13. An electric push rod 25 is fixedly mounted on the upper surface of the mounting base, and the output shaft of the electric push rod 25 is fixedly connected to the sliding plate 26.

[0038] In this embodiment, the sliding plate 26 is limited by two sliding rods 24, so that the sliding plate 26 can be slidably installed on the upper surface of the mounting box 13. At this time, the electric push rod 25 on the mounting base extends and retracts. The extension and retraction of the electric push rod 25 can drive the sliding plate 26 to reciprocate along the sliding rod 24.

[0039] In actual use, before testing, the electric push rod 25 on the mounting box 13 extends and retracts, causing the sliding plate 26 to move back and forth along the sliding rod 24. The sliding plate 26 drives the brush 29 to move synchronously through the support rod 27 and support block 28, wiping and cleaning the dust on the surface of the liquid storage tube 11 to ensure the detection surface of the temperature probe 16 is clean. After dust removal, the lifting assembly is started. The motor 30 drives one of the threaded rods 17 to rotate through the meshing of the second gear 45 and the first gear 44. Under the action of the synchronous pulley 42 and the synchronous belt 43, the two threaded rods 17 rotate synchronously, driving the lifting block 19 and the lifting plate 14 to move up and down. When plate 14 moves down, it causes disassembly plate 15 and temperature probe 16 to approach liquid storage tube 11. After temperature probe 16 comes into contact with liquid storage tube 11, lifting plate 14 continues to move down, buffer assembly plays its role, buffer rod 20 passes through lifting plate 14 and is limited by buffer ring 22, first spring 21 is compressed, converting the rigid driving force of lifting plate 14 into elastic thrust, avoiding hard contact between temperature probe 16 and liquid storage tube 11, realizing buffer protection. After temperature probe 16 and liquid storage tube 11 are stably attached, temperature detection is completed. After detection ends, lifting assembly drives lifting plate 14 to move up, temperature probe 16 returns to its original position with disassembly plate 15, and detection ends.
