Description

Technical Field

[0001] This utility model relates to the field of compression instrument technology, specifically a temperature control device for compression instruments. Background Technology

[0002] After the air compressor compresses the air, it is cooled by the pre-cooling system. The molecular sieve system adsorbs impurities in the air and then divides it into two paths. One path directly enters the heat exchanger system to exchange heat with the low-temperature gas flowing back into the fractionation tower before entering the distillation tower for distillation. The other path is cooled by the expander system before entering the distillation tower for distillation, producing oxygen, nitrogen, argon, liquid oxygen, liquid nitrogen, and liquid argon.

[0003] A relevant reference is Chinese utility model patent CN212910103U, which discloses a compressed air heating and temperature control device. The device includes a compressed air tank, an inlet connected to an inlet pipe for introducing compressed air, and an outlet connected to an outlet pipe, which is connected to a purge connector for an analytical instrument. Heating resistance wires are wound around the outer periphery of the compressed air tank, inlet pipe, and outlet pipe. These heating resistance wires are connected to a heating and temperature control device to heat and control their temperature, thereby maintaining the compressed air in the tank, inlet pipe, and outlet pipe at a set temperature. This device helps maintain the required temperature for the compressed air used for purging, thus reducing the impact of purging on flue gas analysis.

[0004] The temperature inside the pipeline of the existing compression instrument is not easy to adjust and control during use. Changes in the temperature inside the compression instrument pipeline will affect the operation of the equipment, and the inability to control the temperature will lead to the inability to control the equipment.

[0016] Compared with the prior art, the present invention provides a temperature control device for a compression instrument, which has the following advantages:

[0017] 1. This utility model fills the gap between the heat-conducting copper tube and the instrument tube by using a silicone grease layer on the outside of the instrument tube. The temperature-controlling copper tube can be fixed by the fixing groove inside the heat-conducting copper tube. The temperature-controlling copper tube can control the temperature of the instrument tube.

[0027] Please see Figure 1 - Figure 4 In this embodiment, a compression instrument temperature control device includes: an instrument tube 1, a silicone grease layer 13 fixedly installed on the outer side of the middle of the instrument tube 1, a heat-conducting copper tube 14 fixedly installed on the outer side of the silicone grease layer 13, a fixing groove 15 fixedly installed inside the heat-conducting copper tube 14, the fixing groove 15 being threaded, two temperature detectors 11 fixedly installed on both sides of the instrument tube 1, and a display screen 12 fixedly installed on the top of the temperature detectors 11.

[0028] Specifically, the gap between the instrument tube 1 and the heat-conducting copper tube 14 can be filled by the silicone grease layer 13 to conduct heat, the temperature control copper tube 2 can be fixed by the fixing groove 15, the temperature detector 11 can detect the temperature on both sides inside the instrument tube 1, and the detected temperature can be displayed by the display screen 12.

[0029] Two sets of temperature-controlled copper tubes 2 are fixedly installed inside the fixed tank 15. A liquid extraction pipe 21 is fixedly installed on one side of the top of the temperature-controlled copper tube 2. A switch valve 22 is fixedly installed on one side of the liquid extraction pipe 21. A delivery pipe 23 is fixedly installed on one side of the bottom of the heat-conducting copper tube 14. A merging valve 24 is fixedly installed on one side of the delivery pipe 23. An air inlet pipe 25 is fixedly installed on one side of the merging valve 24. A control valve 26 is fixedly installed in the middle of the air inlet pipe 25. An inlet pipe 27 is fixedly installed on the top of the merging valve 24. An installation valve 28 is fixedly installed in the middle of the inlet pipe 27.

[0030] Specifically, the liquid inside the temperature-controlled copper tube 2 can be extracted through the extraction pipe 21 and sent into the heating device 34 or the cooling device 35, and the liquid can be sent into the delivery pipe 23 through the merging valve 24 via the inlet pipe 27.

[0031] An outer casing 3 is fixedly installed on the outside of the instrument tube 1. An insulation cotton 31 is fixedly installed on the outside of the outer casing 3. An insulation layer 32 is fixedly installed on the outside of the insulation cotton 31. Support plates 33 are fixedly installed on both sides of the insulation layer 32. A heating device 34 is fixedly installed on one side of the support plate 33. A cooling device 35 is fixedly installed on the other side of the support plate 33.

[0032] Specifically, the heating device 34 and the cooling device 35 can be supported by the support plate 33, the heat insulation cotton 31 on the outside of the outer shell 3 can be used for heat preservation, and the heat insulation layer 32 on the outside of the heat insulation cotton 31 can be used for heat insulation treatment to prevent heat loss.

[0033] In use, firstly, the temperature of both sides of the instrument tube 1 can be detected by the two temperature detectors 11 on both sides of the instrument tube 1 and displayed on the display screen 12, so as to facilitate the detection and control of the internal temperature of the instrument tube 1, improving the practicality and convenience of the compressor instrument temperature control device.

The merging valve 24 then sends the coolant into the delivery pipe 23, and finally, the delivery pipe 23 sends the coolant into the temperature-controlled copper tube 2. The temperature-controlled copper tube 2 conducts heat to the coolant, thus cooling the heat-conducting copper tube 14. The silicone grease layer 13 fills the gap between the heat-conducting copper tube 14 and the instrument tube 1, allowing the temperature of the heat-conducting copper tube 14 to cool the internal temperature of the instrument tube 1, improving the usability of the compressor instrument temperature control device. In addition to temperature control, the coolant inside the temperature-controlled copper tube 2 can be extracted through the extraction pipe 21 and sent to the cooling device 35 for cooling circulation, improving the practicality of the compressor temperature control device. When the compressor temperature control device needs to be heated, the installation valve 28 is closed, the inlet pipe 27 is closed, and the control valve 26 is opened, allowing air to enter through the air inlet pipe 25. This allows air to enter through the merging valve 24, extracting the coolant inside the temperature-controlled copper tube 2. After extraction, the control valve 26 and the switch valve 22 are closed, thus shutting off the set of temperature-controlled copper tubes 2. Through the operation of the heating device 34, heating liquid can enter from another set of temperature-controlled copper tubes 2 for heating, improving the practicality and convenience of the compressor temperature control device. The insulation cotton 31 and the insulation layer 32 on the outside of the outer shell 3 can achieve the effect of heat preservation and insulation. The support plate 33 can support the heating device 34 and the cooling device 35, improving the practicality of the compressor temperature control device.
