Description

Technical Field

[0001] This utility model relates to the field of gelatin drying technology, and more specifically, to a processing system. Background Technology

[0002] Gelatin is a collagen protein extracted from animal connective tissue or bone, widely used in food, cosmetics, pharmaceuticals, photography, and industry. The gelatin drying process is a crucial step in gelatin production. Gelatin solution with a water content of 70% is gradually dried to approximately 8% water content using a long-net drying line, transforming it into dry gelatin for storage, transportation, and subsequent applications. The long-net drying line is divided into multiple drying sections, equipped with a circulating air heating system, with the drying temperature gradually increasing. Fresh air is supplied to the drying line to remove high-temperature, high-humidity exhaust air, achieving dehumidification of the production line. Generally, a rotary dehumidifier is used to treat the fresh air to a low-humidity state before sending it into the drying line. Simultaneously, multiple heaters are installed on the drying line to output high-temperature air to dry the gelatin.

[0003] However, the dehydration and regeneration process of a rotary dehumidifier requires a large amount of heat energy; at the same time, the heater outputting high-temperature air also requires a large amount of heat energy, which usually comes from steam generated by a gas boiler. The high energy consumption during operation leads to high natural gas costs. Utility Model Content

[0015] The processing system using the technical solution of this utility model includes a first temperature regulating component, a first heating component, a drying unit, a liquefaction heating component, and a first solution heat exchanger. When the processing system is in dehumidification mode, when the fresh air with high humidity flows through the first temperature regulating component, the temperature regulating medium inside the first temperature regulating component vaporizes and absorbs heat to cool and dehumidify the fresh air, forming low-humidity fresh air. Then, the fresh air flowing out of the first temperature regulating component flows through the liquefaction heating component for heating. The heated fresh air flowing out of the liquefaction heating component flows into the ventilation area of ​​the drying unit to form high-temperature exhaust air. Then, the high-temperature exhaust air flowing out of the drying unit flows through the first solution heat exchanger and exchanges heat with the heat exchange liquid inside the first solution heat exchanger.

The high-temperature liquid is used to enter the heating channel of the heater so that the heater outputs high-temperature air to heat and dry the workpiece. When the processing system is in ventilation mode, the low-humidity fresh air flows through the first temperature regulator, which heats the air. The fresh air exiting the first temperature regulator then flows through the first heating element for further heating. The low-humidity fresh air exiting the first heating element passes through the ventilation area of ​​the drying unit to form exhaust air, which then flows into the first solution heat exchanger. Therefore, regardless of whether the processing system is in dehumidification or ventilation mode, the first solution heat exchanger can recover heat from the high-temperature exhaust air, heating the low-temperature liquid to form a high-temperature liquid. This high-temperature liquid can serve as the heat source for the heater, eliminating reliance on boiler hot water and significantly saving energy required for drying the workpiece. Furthermore, when the processing system is in dehumidification mode, the first temperature regulator replaces the rotary dehumidifier for cooling and dehumidifying the fresh air, further saving energy. This results in low energy consumption, significantly reduced operating costs, and improved economic efficiency for the processing system. Attached Figure Description

Detailed Implementation

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Please refer to Figure 1This utility model provides a processing system, comprising: a first temperature regulating component 31, which contains a low-pressure temperature regulating medium; when the processing system is in dehumidification mode, the first temperature regulating component 31 vaporizes the low-pressure temperature regulating medium to cool and dehumidify the fresh air passing through it, forming low-humidity fresh air; when the processing system is in ventilation mode, the first temperature regulating component 31 heats the low-humidity fresh air; a liquefaction heating component 34, which contains a high-pressure temperature regulating medium to liquefy the low-humidity fresh air flowing out of the liquefaction heating component 34; and a first heating component 41, which is connected to the liquefaction heating component 31. 4. A connection is established to heat the low-humidity fresh air flowing out from the liquefied heating element 34; a drying unit 5 has an air exchange area and a heating channel, and the part to be dried is arranged in the air exchange area. The air exchange area of ​​the drying unit 5 is connected to the first heating element 41 so that the low-humidity fresh air flowing out from the first heating element 41 passes through the air exchange area of ​​the drying unit 5 to form exhaust air; a first solution heat exchanger 51 is used to contain heat exchange liquid inside. The first solution heat exchanger 51 is connected to the air exchange area so that the heat exchange liquid and the exhaust air flowing out from the air exchange area exchange heat, and then exchange heat with the low-temperature liquid 2 to form a high-temperature liquid 1; wherein, the high-temperature liquid 1 is used to enter the heating channel to heat and dry the part to be dried.

[0022] The processing system of this utility model includes a first temperature regulating element 31, a first heating element 41, a drying unit 5, a liquefaction heating element 34, and a first solution heat exchanger 51. When the processing system is in dehumidification mode, when the fresh air with high humidity flows through the first temperature regulating element 31, the temperature regulating medium inside the first temperature regulating element 31 vaporizes and absorbs heat to cool and dehumidify the fresh air, forming low-humidity fresh air. Then, the fresh air flowing out of the first temperature regulating element 31 flows through the liquefaction heating element 34 for heating, and the heated fresh air flowing out of the liquefaction heating element 34 flows into the drying unit 5. The air exchange area of ​​the drying unit 5 forms high-temperature exhaust air. The high-temperature exhaust air flowing out of the drying unit 5 then flows through the first solution heat exchanger 51 and exchanges heat with the heat exchange liquid inside the first solution heat exchanger 51. The heat exchange liquid then exchanges heat with the low-temperature liquid 2 outside the first solution heat exchanger 51, so that the heat of the high-temperature exhaust air is transferred to the low-temperature liquid 2 through the heat exchange liquid, causing the low-temperature liquid 2 to be heated to form high-temperature liquid 1. The high-temperature liquid 1 is used to enter the heating channel of the heater so that the heater outputs high-temperature air to heat and dry the workpiece. When the processing system is in ventilation mode, when the low-humidity fresh air flows through the first temperature regulating element 31, the first temperature regulating element 31 heats the low-humidity fresh air. Then, the fresh air flowing out of the first temperature regulating element 31 flows through the first heating element 41 for heating. The low-humidity fresh air flowing out of the first heating element 41 passes through the air exchange area of ​​the drying unit 5 to form exhaust air, and then the high-temperature exhaust air flows into the first solution heat exchanger 51. Therefore, regardless of whether the processing system of this utility model is in dehumidification mode or ventilation mode, it can utilize the first solution heat exchanger 51 to recover heat from the high-temperature exhaust air, thereby heating the low-temperature liquid 2 to form a high-temperature liquid 1. The high-temperature liquid 1 can serve as the heat energy source for the heater, so that the heat energy source for the heater does not solely rely on boiler hot water, greatly saving the energy required to dry the parts to be dried. In addition, when the processing system is in dehumidification mode, the first temperature regulating element 31 replaces the rotary dehumidifier to cool and dehumidify the fresh air, which can greatly save the energy required to cool and dehumidify the fresh air. As a result, the processing system of this utility model has low operating energy consumption, significantly reduces the operating cost of the processing system, and improves the economy of the processing system.

[0023] Specifically, in the prior art, the heating channel inside the heater is circulated with boiler hot water, and the heat exchange channel inside the heater is circulated with ambient air. The boiler hot water and ambient air exchange heat in the heater, so that the ambient air is heated to form high-temperature air, which then heats and dries the workpiece.

[0024] The heating channel of the drying unit 5 in this application is arranged inside the heater. High-temperature liquid 1 is used to enter the heating channel of the heater to exchange heat with the room temperature air inside the heater. The room temperature air is heated to form high-temperature air and then introduced into the ventilation area of ​​the drying unit 5 to heat and dry the workpiece.

[0025] Specifically, such as Figure 1 As shown, multiple drying sections for gelatin are arranged in an orderly manner within the ventilation area of ​​the drying unit 5. There are multiple heaters. The high-temperature air temperature required for the preceding drying section is lower than that required for the following drying section. The heat source for the heaters corresponding to the preceding drying section comes from the high-temperature liquid 1. When the heat provided by the high-temperature liquid 1 is insufficient, the heat source for the heaters corresponding to the following drying section is supplemented by the heat from the boiler hot water. The boiler hot water supply 7 flows into the heating channel of the heater, exchanges heat with the ambient temperature air, and then flows out of the boiler hot water return 8.

[0026] Optionally, the first temperature regulating element 31 is a direct expansion evaporator, replacing the rotary dehumidifier. The first temperature regulating element 31 can directly cool the fresh air, reducing energy consumption.

[0027] In this embodiment, the processing system further includes a second temperature regulating component 35. The first temperature regulating component 31 and the second temperature regulating component 35 are connected to exchange the temperature regulating medium in the first temperature regulating component 31 and the temperature regulating medium in the second temperature regulating component 35. The second temperature regulating component 35 is connected to the first solution heat exchanger 51. When the processing system is in dehumidification mode, the second temperature regulating component 35 heats the exhaust air flowing out of the first solution heat exchanger 51. When the processing system is in ventilation mode, the second temperature regulating component 35 cools the exhaust air flowing out of the first solution heat exchanger 51.

[0028] Specifically, when the processing system is in dehumidification mode, after the high-temperature exhaust air flows through the first solution heat exchanger 51, the high-temperature exhaust air becomes low-temperature exhaust air. The low-temperature exhaust air flowing out of the first solution heat exchanger 51 flows into the second temperature regulating element 35. Since the temperature of the temperature regulating medium flowing from the first temperature regulating element 31 into the second temperature regulating element 35 is relatively high (the temperature regulating medium in the first temperature regulating element 31 absorbs heat from the fresh air and flows into the second temperature regulating element 35; most of the heat of the temperature regulating medium is used for heat exchange with the fresh air in the liquefaction heating element 34, and the excess heat flows into the second temperature regulating element 35, at which time the second temperature regulating element 35 also plays a role in auxiliary heat dissipation), the temperature regulating medium in the second temperature regulating element 35 can exchange heat with the low-temperature exhaust air flowing through the second temperature regulating element 35, heating the low-temperature exhaust air and turning it into medium-temperature exhaust air. At the same time, the temperature of the temperature regulating medium in the second temperature regulating element 35 becomes lower after exchanging heat with the low-temperature exhaust air, and then the temperature regulating medium in the second temperature regulating element 35 returns to the first temperature regulating element 31. Continuing to cool the low-humidity fresh air allows the processing system to fully recover and utilize the heat from the fresh air and exhaust air, further reducing the operating energy consumption of the processing system of this utility model. When the processing system is in ventilation mode, because the temperature of the temperature regulating medium flowing from the first temperature regulating element 31 into the second temperature regulating element 35 is low (the heat of the temperature regulating medium in the first temperature regulating element 31 is transferred to the low-humidity fresh air and then flows into the second temperature regulating element 35), the temperature regulating medium in the second temperature regulating element 35 can exchange heat with the low-temperature exhaust air flowing through the second temperature regulating element 35, cooling the low-temperature exhaust air. The cooled exhaust air is then discharged to the outside, reducing the temperature of the exhaust air discharged to the outside, thereby reducing the heat emission of the processing system to the environment, meeting environmental protection requirements, and helping to reduce the greenhouse effect and heat island effect. At the same time, the temperature of the temperature regulating medium in the second temperature regulating element 35 becomes higher after exchanging heat with the low-temperature exhaust air, and then the temperature regulating medium in the second temperature regulating element 35 returns to the first temperature regulating element 31 to continue heating the low-humidity fresh air, making full use of the heat of the exhaust air.

[0029] In this embodiment, the processing system further includes a sixth reflux medium pipeline 671, a second solution heat exchanger 61, and the airflow channel outlet and airflow channel inlet of the second temperature regulating element 35 are respectively connected to the airflow inlet of the second solution heat exchanger 61 and the airflow outlet of the first solution heat exchanger 51. The inflow end of the sixth reflux medium pipeline 671 is connected to the airflow channel outlet of the second temperature regulating element 35, and the sixth reflux medium pipeline 671 can be switched on and off.

[0030] Specifically, the outlet of the sixth return medium pipeline 671 is connected to the outside. When the processing system is in dehumidification mode, the sixth return medium pipeline 671 is disconnected. At this time, the medium-temperature exhaust air flowing out from the second temperature regulating element 35 flows through the second solution heat exchanger 61 and exchanges heat with the heat exchange liquid inside the second solution heat exchanger 61. The heat exchange liquid then exchanges heat with the medium-temperature liquid return water 9 outside the second solution heat exchanger 61, so that the heat of the medium-temperature exhaust air is transferred to the medium-temperature liquid return water 9 through the heat exchange liquid, so that the medium-temperature liquid return water 9 is heated to form medium-temperature liquid 4, which is used for domestic or other processes. The setting of the second temperature regulating element 35 and the second solution heat exchanger 61 enables the processing system to fully recover and utilize the heat in the fresh air and exhaust air, further reducing the operating energy consumption of the processing system of this utility model. When the processing system is in ventilation mode, the low-temperature exhaust air flowing out from the second temperature regulator 35 basically flows through the sixth return medium pipeline 671 to the outside. The sixth return medium pipeline 671 can reduce the flow resistance of the exhaust air to the outside.

[0031] In this embodiment, a fifth valve 67 is provided on the sixth return medium pipeline 671. The fifth valve 67 is configured to be openable and closable to control the connection of the sixth return medium pipeline 671 when the processing system is in ventilation mode; and to control the disconnection of the sixth return medium pipeline 671 when the processing system is in dehumidification mode.

[0032] Specifically, by controlling the opening and closing of the fifth valve 67, the flow of the sixth return medium pipeline 671 can be controlled. This ensures that when the processing system is in ventilation mode, opening the fifth valve 67 to connect the sixth return medium pipeline 671 reduces the flow resistance of the exhaust air to the outside. When the processing system is in dehumidification mode, closing the fifth valve 67 disconnects the sixth return medium pipeline 671, preventing the medium-temperature exhaust air from flowing out of the sixth return medium pipeline 671 and failing to enter the second solution heat exchanger 61, thus ensuring that the heat from the medium-temperature exhaust air is fully utilized.

[0033] In this embodiment, the processing system further includes a first reflux medium pipeline 311, a second reflux medium pipeline 312, a third reflux medium pipeline 313, and a fourth reflux medium pipeline 314. The inflow and outflow ends of the first reflux medium pipeline 311 and the third reflux medium pipeline 313 are respectively connected to the first temperature regulating element 31 and the second temperature regulating element 35. The inflow and outflow ends of the second reflux medium pipeline 312 and the fourth reflux medium pipeline 314 are respectively connected to the second temperature regulating element 35 and the first temperature regulating element 31. The on / off states of the first reflux medium pipeline 311, the second reflux medium pipeline 312, the third reflux medium pipeline 313, and the fourth reflux medium pipeline 314 can all be adjusted.

[0034] Specifically, by connecting the first return medium pipeline 311 and the second return medium pipeline 312, and disconnecting the third return medium pipeline 313 and the fourth return medium pipeline 314, the processing system is switched to dehumidification mode; by disconnecting the first return medium pipeline 311 and the second return medium pipeline 312, and connecting the third return medium pipeline 313 and the fourth return medium pipeline 314, the processing system is switched to ventilation mode.

[0035] In this embodiment, a first expansion valve 36 is provided on the second return medium pipeline 312, and a first valve 334 is provided on the fourth return medium pipeline 314. The first expansion valve 36 and the first valve 334 are configured to be openable and closable. When the processing system is in dehumidification mode, the first expansion valve 36 is open and the first valve 334 is closed. When the processing system is in ventilation mode, the first expansion valve 36 is closed and the first valve 334 is open.

[0036] Specifically, the processing system also includes a humidity detection device. When the humidity detection device detects that the humidity of the fresh air entering the first temperature regulator 31 is low and dehumidification is not required, it closes the first expansion valve 36 and opens the first valve 334, thereby disconnecting the second return medium pipeline 312 and connecting the fourth return medium pipeline 314. At this time, the higher temperature regulating medium flowing out of the second temperature regulator 35 flows into the first temperature regulator 31 through the first valve 334 to continue heating the fresh air. When the humidity detection device detects that the humidity of the fresh air entering the first temperature regulator 31 is high and dehumidification is required, it opens the first expansion valve 36 and closes the first valve 334, thereby connecting the second return medium pipeline 312 and opening the fourth return medium pipeline 314. At this time, the high-pressure temperature regulating medium flowing out of the second temperature regulator 35 is depressurized through the first expansion valve 36, converting it to a low-pressure state. Then, the low-pressure temperature regulating medium flows into the first temperature regulator 31 to continue cooling and dehumidifying the fresh air.

[0037] In this embodiment, the first return medium pipeline 311 includes a first sub-return liquid pipeline section 315 and a second sub-return liquid pipeline section 316. The inflow end and outflow end of the first sub-return liquid pipeline section 315 are respectively connected to the first temperature regulating element 31 and the liquefaction heating element 34. The inflow end and outflow end of the second sub-return liquid pipeline section 316 are respectively connected to the liquefaction heating element 34 and the second temperature regulating element 35. The on / off state of the first sub-return liquid pipeline section 315 and the second sub-return liquid pipeline section 316 is adjustable. A pressure boosting element 32 is provided on the first sub-return liquid pipeline section 315.

[0038] Specifically, when the processing system is in dehumidification mode, the first sub-return liquid pipe section 315 and the second sub-return liquid pipe section 316 are connected, and the third return medium pipe 313 is disconnected. The low-pressure temperature regulating medium flowing out of the first temperature regulating element 31 is pressurized by the pressurizing element 32 and becomes a high-pressure temperature regulating medium. Then, the high-pressure temperature regulating medium flows into the liquefaction heating element 34. The liquefaction heating element 34 is liquefied by the high-pressure temperature regulating medium to heat the low-humidity fresh air flowing out of the first temperature regulating element 31. The higher-temperature temperature regulating medium in the liquefaction heating element 34 flows into the second temperature regulating element 35. When the processing system is in ventilation mode, the first sub-return liquid pipe section 315 and the second sub-return liquid pipe section 316 are disconnected, and the third return medium pipe 313 is connected. The temperature of the temperature regulating medium in the first temperature regulating element 31 is lower, and it flows directly into the second temperature regulating element 35 through the third return medium pipe 313.

[0039] In this embodiment, a second valve 331 is provided on the first sub-return liquid pipe section 315, a third valve 332 is provided on the second sub-return liquid pipe section 316, and a fourth valve 333 is provided on the third return medium pipe 313. The second valve 331, the third valve 332, and the fourth valve 333 can all be opened and closed. A fluorine pump 37 is provided on the third return medium pipe 313 to provide power for the flow of the temperature regulating medium in the third return medium pipe 313.

[0040] Specifically, the processing system also includes a humidity detection device. When the humidity detection device detects that the humidity of the fresh air entering the first temperature regulator 31 is too high and dehumidification is required, it opens the second valve 331 and the third valve 332 and closes the fourth valve 333, thereby connecting the first sub-return liquid pipe section 315 and the second sub-return liquid pipe section 316 and disconnecting the third return medium pipe 313. When the humidity detection device detects that the humidity entering the first temperature regulator 31 is too low and dehumidification is not required, it closes the second valve 331 and the third valve 332 and opens the fourth valve 333, thereby disconnecting the first sub-return liquid pipe section 315 and the second sub-return liquid pipe section 316 and connecting the third return medium pipe 313.

[0041] Optionally, the second valve 331, the third valve 332, the fourth valve 333, and the first valve 334 are all solenoid valves. The processing system also includes a controller, which is communicatively connected to the humidity detection element, the second valve 331, the third valve 332, the fourth valve 333, and the first valve 334 to control the opening and closing of the second valve 331, the third valve 332, the fourth valve 333, and the first valve 334 according to the detection result of the humidity detection element.

[0042] In this embodiment, the processing system further includes a first cooling element 11 and a second heating element 12. One end of the airflow channel of the first cooling element 11 is used to introduce fresh air, and the first cooling element 11 is used to exchange heat with the fresh air flowing through it to cool and dehumidify the fresh air. The other end of the airflow channel of the first cooling element 11 is connected to the airflow channel of the first temperature regulating element 31. The second heating element 12 is used to exchange heat with the low-humidity fresh air flowing through it to heat the low-humidity fresh air. The airflow channel inlet and outlet of the second heating element 12 are respectively connected to the airflow channel of the first temperature regulating element 31 and the airflow channel of the liquefaction heating element 34. The heat exchange channels of the first cooling element 11 and the second heating element 12 are connected to exchange the temperature regulating medium within the first cooling element 11 and the second heating element 12. This arrangement allows the low-humidity fresh air flowing out of the first temperature regulating element 31 to be heated sequentially via the second heating element 12 and the liquefaction heating element 34.

[0043] In this embodiment, the processing system further includes a third exchange medium pipeline and a fourth exchange medium pipeline. The inlet and outlet of the third exchange medium pipeline are respectively connected to the heat exchange channel of the first cooling element 11 and the heat exchange channel of the second heating element 12. The inlet and outlet of the fourth exchange medium pipeline are respectively connected to the heat exchange channel of the second heating element 12 and the heat exchange channel of the first cooling element 11, so as to exchange the temperature regulating medium in the second heating element 12 and the first cooling element 11, so as to realize the recycling of the temperature regulating medium and help reduce the operating energy consumption of the processing system of this utility model.

[0044] Specifically, the third and fourth exchange medium pipelines are used to exchange the temperature regulating medium in the second heating element 12 and the first cooling element 11. This allows the temperature regulating medium in the first cooling element 11 to absorb heat from the fresh air and then rise in temperature. The medium then flows into the second heating element 12 to exchange heat with the fresh air flowing through it, transferring the heat to the fresh air. This fully utilizes the heat of the fresh air, further saving the energy required for cooling and dehumidifying the fresh air, and helps reduce the operating energy consumption of the processing system.

[0045] In this embodiment, the processing system further includes a fifth return medium pipeline 381, on which a regulating valve 38 is provided. The opening degree of the regulating valve 38 is adjustable. The inflow end and the outflow end of the fifth return medium pipeline 381 are respectively connected to the airflow channel outlet of the second heating element 12 and the first heating element 41. When the processing system is in ventilation mode, the opening degree of the regulating valve 38 is at its maximum.

[0046] Specifically, the two ends of the airflow channel of the liquefied heating element 34 are connected to the airflow channel outlet of the second heating element 12 and the first heating element 41, respectively. When the processing system is in dehumidification mode, the liquefied heating element 34 heats the low-humidity fresh air flowing out of the first temperature regulating element 31. By adjusting the opening of the regulating valve 38, the air volume heated by the liquefied heating element 34 can be adjusted to achieve the control of the temperature of the fresh air finally flowing into the drying unit 5. When the processing system is in ventilation mode, the liquefied heating element 34 does not work. At this time, the opening of the regulating valve 38 is at its maximum, ensuring that the fresh air flowing out of the second heating element 12 basically flows into the first heating element 41, ensuring the rapid flow of fresh air. In this embodiment, the processing system further includes a cooling assembly, which includes a first cooling element 11 and a second cooling element 21. The temperature regulating medium in the heat exchange channel of the first cooling element 11 is used to exchange heat with the fresh air in the airflow channel of the first cooling element 11 to cool and dehumidify the fresh air. The heat exchange channel of the first cooling element 11 and the heat exchange channel of the second heating element 12 are connected. The second cooling element 21 is used to cool and dehumidify the fresh air. The two ends of the airflow channel of the second cooling element 21 are respectively connected to the airflow channel of the first cooling element 11 and the airflow channel of the first temperature regulating element 31.

[0047] Specifically, when the processing system is in dehumidification mode, fresh air flows through the first cooling component 11, the second cooling component 21 and the first temperature regulating component 31 in sequence, so that the first cooling component 11, the second cooling component 21 and the first temperature regulating component 31 cool the fresh air in sequence, thereby reducing the temperature and humidity of the fresh air.

[0048] Optionally, the temperature regulating medium in the heat exchange channel of the second cooling element 21 is a low-temperature temperature regulating medium 3, i.e., chilled water at 14°C, which can improve the operating efficiency of the second cooling element 21.

[0049] In this embodiment, the processing system further includes: a fourth cooling element 42, having a heat exchange channel and an airflow channel, the two ends of which are respectively connected to the air exchange area of ​​the drying unit 5 and the airflow inlet of the first solution heat exchange element 51, and the temperature regulating medium in the heat exchange channel is used to exchange heat with the exhaust air in the airflow channel of the fourth cooling element 42; a first heating element 41, having a heat exchange channel and an airflow channel, the temperature regulating medium in the heat exchange channel being used to exchange heat with the low-humidity fresh air in the airflow channel of the first heating element 41 to heat the low-humidity fresh air; a first exchange medium pipeline 711 and a second exchange medium pipeline 712, the outlet end and inlet end of the first exchange medium pipeline 711 being respectively connected to the heat exchange channel of the fourth cooling element 42 and the heat exchange channel of the first heating element 41, and the outlet end and inlet end of the second exchange medium pipeline 712 being respectively connected to the heat exchange channel of the first heating element 41 and the heat exchange channel of the fourth cooling element 42 to exchange the temperature regulating medium in the first heating element 41 and the fourth cooling element 42.

[0050] Specifically, the high-temperature exhaust air flowing out from the ventilation area of ​​the drying unit 5 enters the airflow channel of the fourth cooling element 42. The temperature regulating medium in the heat exchange channel of the fourth cooling element 42 exchanges heat with the high-temperature exhaust air in the airflow channel of the fourth cooling element 42, so that the temperature regulating medium in the fourth cooling element 42 is heated and then flows into the first heating element 41 through the second exchange medium pipeline 712. This allows the temperature regulating medium in the first heating element 41 to exchange heat with the low-humidity fresh air flowing through the first heating element 41 to heat the low-humidity fresh air. Then, the temperature regulating medium in the first heating element 41 returns to the fourth cooling element 42 through the first exchange medium pipeline 711 to continue to recover the heat of the high-temperature exhaust air, further making full use of the heat of the high-temperature exhaust air, so as to realize the recycling of the temperature regulating medium and help reduce the operating energy consumption of the processing system of this utility model.

[0051] In this embodiment, a first packed reactor 431 is provided inside the first solution heat exchanger 51. An airflow inlet and a first solution collection section 437 are provided at the bottom of the first solution heat exchanger 51. A first spray section 432 and an airflow outlet are provided at the top of the first solution heat exchanger 51. The first spray section 432 is used to spray the heat exchange liquid. The first packed reactor 431 is disposed between the airflow inlet and the first spray section 432 so that the exhaust air flowing in from the airflow inlet can contact the heat exchange liquid for heat exchange.

[0052] Specifically, the first packed reactor 431 increases the contact time between the exhaust air and the concentrated solution, ensuring that the exhaust air and the heat exchange liquid are in full contact and heat exchange within the first packed reactor 431, ensuring that the heat exchange liquid is fully heated, and avoiding the low temperature of the heat exchange liquid flowing out from the first solution heat exchanger 51, or the insufficient utilization of the heat from the exhaust air.

[0053] Specifically, the structure of the second solution heat exchanger 61 is the same as that of the first solution heat exchanger 51.

[0054] In this embodiment, the processing system further includes a first diversion medium pipeline 531, a first pump body 52, and a first evaporator 53. The first pump body 52 is disposed on the first diversion medium pipeline 531. The inflow end and the outflow end of the first diversion medium pipeline 531 are respectively connected to the first solution collection section 437 and the first spray section 432 of the first solution heat exchanger 51. The first evaporator 53 is used to contain a low-pressure temperature regulating medium so that the low-pressure temperature regulating medium is vaporized to cool the heat exchange liquid flowing into the first spray section 432.

[0055] Specifically, the first diversion medium pipeline 531 connects the first solution collection section 437 and the first spray section 432 of the first solution heat exchanger 51, ensuring that the heat exchange liquid can circulate between the first solution collection section 437 and the first spray section 432. The first solution collection section 437 collects the heat exchange liquid whose temperature has increased after heat exchange with the exhaust air in the first solution heat exchanger 51; the first spray section 432 sprays the cooled heat exchange liquid into the first solution heat exchanger 51, allowing it to further contact the exhaust air and achieve heat exchange. The first pump body 52 provides power for the circulation of the heat exchange liquid, ensuring that the heat exchange liquid can circulate in the first solution heat exchanger 51 at an appropriate speed, thereby improving the heat exchange efficiency of the first solution heat exchanger 51. The first evaporator 53 is used to circulate and absorb heat from the heat exchange liquid, cooling the circulating heat exchange liquid. By setting up the first diversion medium pipeline 531, the first pump body 52 and the first evaporator 53, the heat exchange liquid can more effectively absorb the heat in the exhaust air each time it comes into contact with the exhaust air, which significantly improves the heat recovery efficiency of the exhaust air.

[0056] In this embodiment, the processing system further includes a second diversion medium pipeline 537. Both the second diversion medium pipeline 537 and the first diversion medium pipeline 531 flow through the first evaporator 53, so that the temperature regulating medium in the second diversion medium pipeline 537 and the heat exchange liquid in the first diversion medium pipeline 531 exchange heat, and then exchange heat with the low temperature liquid 2 to form a high temperature liquid 1.

[0057] Specifically, by exchanging heat between the temperature regulating medium in the second diversion medium pipeline 537 and the heat exchange liquid in the first diversion medium pipeline 531, not only can the heat exchange liquid flowing into the first spray section 432 be prevented from overheating, but it also ensures that the temperature regulating medium in the second diversion medium pipeline can be fully heated and then exchange heat with the low-temperature liquid 2 to form a high-temperature liquid 1.

[0058] In this embodiment, the processing system further includes a third heat exchanger 55 and a third diversion medium pipeline 538. The second diversion medium pipeline 537 and the third diversion medium pipeline 538 both flow through the third heat exchanger 55. The third heat exchanger 55 is provided with a high-pressure temperature regulating medium, so as to liquefy the high-pressure temperature regulating medium to exchange heat with the low-temperature liquid 2 in the third diversion medium pipeline 538.

[0059] Specifically, heat exchange is performed between the temperature regulating medium in the second diversion medium pipeline 537 and the cryogenic liquid 2 in the third diversion medium pipeline 538, ensuring that the cryogenic liquid 2 in the third diversion medium pipeline 538 can be fully heated to form a high-temperature liquid 1.

[0060] Specifically, the fresh air temperature entering the ventilation area of ​​the drying unit 5 can generally reach 30-35℃, the exhaust air temperature can reach 60℃, and the high-temperature liquid 1 flowing out from the second solution heat exchanger 61 is high-temperature hot water above 60℃.

[0061] Specifically, the second distribution medium pipeline 537 includes two distribution pipe sections. The inlet and outlet ends of one distribution pipe section are respectively connected to the outlet end of a heat exchange channel in the first evaporator 53 and the inlet end of a heat exchange channel in the third heat exchanger 55. The outlet and inlet ends of the other distribution pipe section are respectively connected to the inlet end of a heat exchange channel in the first evaporator 53 and the outlet end of a heat exchange channel in the third heat exchanger 55. The first distribution medium pipeline 531 flows through another heat exchange channel in the first evaporator 53, and the third distribution medium pipeline 538 flows through another heat exchange channel in the third heat exchanger 55. A first compressor 54 and a first expansion valve 56 are provided on the second distribution medium pipeline 537. The first compressor 54 is located between the outlet end of the first evaporator 53 and the inlet end of the third heat exchanger 55, and the first expansion valve 56 is located between the inlet end of the first evaporator 53 and the outlet end of the third heat exchanger 55. The low-pressure temperature regulating medium in the first evaporator 53 changes from a liquid to a gaseous state, absorbing heat from the heat exchange liquid flowing out of the first solution heat exchanger 51. Then, the temperature regulating medium in the first evaporator 53 flows into the first compressor 54. The first compressor 54 compresses the low-pressure temperature regulating medium from the first evaporator 53 into a high-pressure temperature regulating medium. The high-pressure temperature regulating medium then flows into the third heat exchanger 55, where it liquefies to exchange heat with the low-temperature liquid 2 in the third diversion medium pipeline 538. The high-pressure temperature regulating medium flowing out of the third heat exchanger 55 then flows into the first expansion valve 56. The first expansion valve 56 depressurizes the high-pressure temperature regulating medium, turning it into a low-pressure temperature regulating medium, which then flows back into the first evaporator 53, thus achieving the recycling of the temperature regulating medium. Simultaneously, the first expansion valve 56 controls the flow rate of the temperature regulating medium, ensuring sufficient temperature regulating medium evaporation in the first evaporator 53 while preventing excessive temperature regulating medium from entering, which could cause incomplete evaporation or "liquid slugging."

[0062] In this embodiment, a second packed reactor 401 is provided inside the second solution heat exchanger 61. An airflow inlet and a second solution collection section 304 are provided at the bottom of the second solution heat exchanger 61. A second spray section 305 and an airflow outlet are provided at the top of the second solution heat exchanger 61. The second spray section 305 is used to spray the heat exchange liquid. The second packed reactor 401 is disposed between the airflow inlet and the second spray section 305 so that the exhaust air flowing in from the airflow inlet can contact the heat exchange liquid for heat exchange.

[0063] In this embodiment, the processing system further includes a first secondary diversion medium pipeline 301, a second pump body 302, and a second evaporator 303. The second pump body 302 is disposed on the first secondary diversion medium pipeline 301. The inflow end and outflow end of the first secondary diversion medium pipeline 301 are respectively connected to the second solution collection section 304 and the second spraying section 305 of the second solution heat exchanger 61. The second evaporator 303 is used to contain a low-pressure temperature regulating medium so that the low-pressure temperature regulating medium is vaporized to cool the heat exchange liquid flowing into the second spraying section 305.

[0064] Specifically, the first branch medium pipeline 301 connects the second solution collection section 304 and the second spray section 305 of the second solution heat exchanger 61, ensuring that the heat exchange liquid can circulate between the second solution collection section 304 and the second spray section 305. The second solution collection section 304 collects the heat exchange liquid whose temperature has increased after heat exchange with the exhaust air in the second solution heat exchanger 61; the second spray section 305 sprays the cooled heat exchange liquid into the second solution heat exchanger 61, allowing it to further contact the exhaust air and achieve heat exchange. The second pump body 302 provides power for the circulation of the heat exchange liquid, ensuring that the heat exchange liquid can circulate in the second solution heat exchanger 61 at an appropriate speed, thereby improving the heat exchange efficiency of the second solution heat exchanger 61. The second evaporator 303 circulates and absorbs heat from the heat exchange liquid, cooling the circulating heat exchange liquid to regulate its temperature and prevent overheating of the heat exchange liquid flowing into the second spray section 305, which would affect the heat exchange performance of the heat exchange liquid. By setting up a first secondary diversion medium pipeline 301, a second pump body 302, a second evaporator 303, and a second evaporator 303, the heat exchange liquid can more effectively absorb heat from the exhaust air each time it comes into contact with the exhaust air, significantly improving the efficiency of heat recovery from the exhaust air.

[0065] In this embodiment, the processing system also includes a second secondary diversion medium pipeline 306. Both the second secondary diversion medium pipeline 306 and the first secondary diversion medium pipeline 301 flow through the second evaporator 303, so that the temperature regulating medium in the second secondary diversion medium pipeline 306 and the heat exchange liquid in the first secondary diversion medium pipeline 301 exchange heat, and then exchange heat with the return water 9 of the medium temperature liquid to form a high temperature liquid 1.

[0066] Specifically, heat exchange is performed between the temperature regulating medium in the second sub-diversion medium pipeline 306 and the heat exchange liquid in the first sub-diversion medium pipeline 301. This not only prevents the heat exchange liquid flowing into the second spray section 305 from overheating, but also ensures that the temperature regulating medium in the second sub-diversion medium pipeline 306 can be fully heated and then exchanged with the return water 9 of the medium-temperature liquid to form the medium-temperature liquid 4.

[0067] In this embodiment, the processing system also includes a fifth heat exchanger 307 and a third secondary diversion medium pipeline 308. The second secondary diversion medium pipeline 306 and the third secondary diversion medium pipeline 308 both flow through the fifth heat exchanger 307. The fifth heat exchanger 307 is equipped with a high-pressure temperature regulating medium, which is liquefied by the high-pressure temperature regulating medium to exchange heat with the return water 9 of the medium-temperature liquid in the third secondary diversion medium pipeline 308.

[0068] Specifically, heat exchange is achieved through the temperature regulating medium in the second sub-diversion medium pipeline 306 and the low-temperature liquid 2 in the third sub-diversion medium pipeline 308, ensuring that the return water 9 of the medium-temperature liquid in the third sub-diversion medium pipeline 308 can be fully heated to form the medium-temperature liquid 4.

[0069] Specifically, the second sub-distribution medium pipeline 306 includes two liquid distribution pipe sections. The inlet and outlet ends of one liquid distribution pipe section are respectively connected to the outlet end of a heat exchange channel in the second evaporator 303 and the inlet end of a heat exchange channel in the fifth heat exchanger 307. The outlet and inlet ends of the other liquid distribution pipe section are respectively connected to the inlet end of a heat exchange channel in the second evaporator 303 and the outlet end of a heat exchange channel in the fifth heat exchanger 307. The first sub-distribution medium pipeline 301 flows through another heat exchange channel in the second evaporator 303, and the third sub-distribution medium pipeline 308 flows through another heat exchange channel in the fifth heat exchanger 307. The second secondary distribution medium pipeline 306 is equipped with a second compressor 309 and a second expansion valve 300. The second compressor 309 is located between the outlet end of the second evaporator 303 and the inlet end of the fifth heat exchanger 307, and the second expansion valve 300 is located between the inlet end of the second evaporator 303 and the outlet end of the fifth heat exchanger 307. The low-pressure temperature regulating medium in the second evaporator 303 changes from liquid to gas, absorbing heat from the heat exchange liquid flowing out of the first solution heat exchanger 51. Then, the temperature regulating medium in the second evaporator 303 flows into the second compressor 309. The second compressor 309 compresses the low-pressure temperature regulating medium from the second evaporator 303 into a high-pressure temperature regulating medium. Then, the high-pressure temperature regulating medium flows into the fifth heat exchanger 307. The high-pressure temperature regulating medium in the fifth heat exchanger 307 liquefies to exchange heat with the return water 9 of the medium-temperature liquid in the third secondary diversion medium pipeline 308. Then, the high-pressure temperature regulating medium flowing out of the fifth heat exchanger 307 flows into the second expansion valve 300. The second expansion valve 300 depressurizes the high-pressure temperature regulating medium, turning it into a low-pressure temperature regulating medium and returning it to the second evaporator 303, thus realizing the recycling of the temperature regulating medium. At the same time, the second expansion valve 300 controls the flow rate of the temperature regulating medium to ensure that there is enough temperature regulating medium to evaporate in the second evaporator 303, while also preventing excessive temperature regulating medium from entering, which could cause incomplete evaporation or "liquid hammer" phenomenon.

[0070] Specifically, such as Figure 1 As shown, the processing system of this utility model has a ventilation mode and a dehumidification mode. When the processing system is in dehumidification mode, the humidity of the fresh air flowing into the processing system is relatively high. The flow path of the fresh air is as follows: first cooling component 11, second cooling component 21, first temperature regulating component 31, second heating component 12, liquefaction heating component 34 and regulating valve 38, first heating component 41, air exchange area of ​​drying unit 5, fourth cooling component 42, first solution heat exchange component 51, second temperature regulating component 35, second solution heat exchange component 61, and then discharged to the outside from the second solution heat exchange component 61. At this point, the fresh air with higher humidity first undergoes pre-cooling and dehumidification via the first cooling element 11 and the second cooling element 21. Then, it passes through the first temperature regulating element 31 to further cool and dehumidify to the required moisture content. The dehumidified, low-humidity fresh air is then heated by the second heating element 12. A portion of the fresh air flowing out of the second heating element 12 enters the liquefaction heating element 34 for further heating before entering the first heating element 41 (at this point, the first heating element 41 does not heat the flowing fresh air). Another portion of the fresh air flowing out of the second heating element 12 enters the regulating valve 38 before entering the first heating element 41 (at this point, the first heating element 41 does not heat the flowing fresh air). Finally, it is sent to the ventilation area of ​​the drying unit 5 to form exhaust air. The exhaust air first... The air flows through the fourth cooling element 42 (at this time, the fourth cooling element 42 does not cool the exhaust air flowing through), and then flows into the first solution heat exchanger 51 to recover the heat in the high-temperature exhaust air and transfer the heat in the high-temperature exhaust air to the low-temperature liquid 2, so that the low-temperature liquid 2 is heated to form high-temperature liquid 1. The high-temperature liquid 1 can be used to heat and dry the workpiece to be dried by passing it into the heating channel of the drying unit 5. The low-temperature exhaust air flowing out from the first solution heat exchanger 51 enters the second temperature regulating element 35 to be heated. The medium-temperature exhaust air flowing out from the second temperature regulating element 35 flows into the second solution heat exchanger 61 to recover the heat in the exhaust air and transfer the heat in the medium-temperature exhaust air to the return water 9 of the medium-temperature liquid to form medium-temperature liquid 4 for domestic or other processes.

[0071] When the processing system is in ventilation mode, the fresh air flowing into the processing system has low humidity and is low-humidity fresh air, so dehumidification is not required. The flow path of the fresh air is as follows: first cooling component 11, second cooling component 21, first temperature regulating component 31, second heating component 12, liquefaction heating component 34 and regulating valve 38, first heating component 41, air exchange area of ​​drying unit 5, fourth cooling component 42, first solution heat exchanger 51, second temperature regulating component 35, fifth valve 67 and second solution heat exchanger 61, and then discharged to the outside from the fifth valve 67 or the second solution heat exchanger 61. Fresh air flows through the first cooling element 11, the second cooling element 21, the first temperature regulating element 31, and the second heating element 12 (at this time, neither the first cooling element 11 nor the second cooling element 21 will cool or dehumidify the low-humidity fresh air, and neither the second heating element 12 nor the liquefaction heating element 34 will heat the low-humidity fresh air; the first temperature regulating element 31 will heat the low-humidity fresh air). A small portion of the low-humidity fresh air flows through the liquefaction heating element 34 and then into the first heating element 41 for heating. Most of the low-humidity fresh air flows through the regulating valve 38 and then into the first heating element 41 for heating. It is then sent into the ventilation area of ​​the drying unit 5 to form exhaust air, which first flows through the fourth cooling element 4. 2. The air is cooled and then flows into the first solution heat exchanger 51 to recover the heat from the high-temperature exhaust air. The heat from the high-temperature exhaust air is transferred to the low-temperature liquid 2 to heat the low-temperature liquid 2 and form a high-temperature liquid 1. The high-temperature liquid 1 can be used to heat and dry the workpiece in the heating channel of the drying unit 5. The low-temperature exhaust air flowing out of the first solution heat exchanger 51 flows through the second temperature regulating element 35 for cooling. Most of the exhaust air flowing out of the second temperature regulating element 35 flows through the fifth valve 67 to the outside, and a small portion of the exhaust air flowing out of the second temperature regulating element 35 flows through the second solution heat exchanger 61 to the outside (at this time, the second solution heat exchanger 61 stops operating). The processing system of this utility model has a high degree of integration, fully recovers the exhaust air energy to prepare the high-temperature liquid 1 as a heat energy source, and uses the heat of the temperature regulating medium in the second temperature regulating element 35 to heat the low-temperature exhaust air to prepare the medium-temperature liquid 4 in the dehumidification mode. The processing system has high efficiency in utilizing exhaust air energy throughout the year, low operating energy consumption, and reduced energy costs.

[0072] Specifically, the first heating element 41 and the fourth cooling element 42 have pumps inside, which can control the flow of the temperature regulating medium inside the first heating element 41 and the fourth cooling element 42 to stop. When the processing system is in dehumidification mode, the flow of the temperature regulating medium inside the first heating element 41 and the fourth cooling element 42 stops, so that the temperature of the temperature regulating medium inside the first heating element 41 is almost the same as the temperature of the incoming fresh air, and the temperature of the temperature regulating medium inside the fourth cooling element 42 is almost the same as the temperature of the incoming exhaust air. Therefore, the first heating element 41 will not heat the incoming fresh air, and the fourth cooling element 42 will not cool the incoming exhaust air.

[0073] Specifically, the second heating element 12 and the first cooling element 11 have pumps inside, which can control the flow of the temperature regulating medium inside the second heating element 12 and the first cooling element 11 to stop. When the processing system is in ventilation mode, the flow of the temperature regulating medium inside the second heating element 12 and the first cooling element 11 stops, so that the temperature of the temperature regulating medium inside the second heating element 12 and the first cooling element 11 is almost the same as the temperature of the low-humidity fresh air flowing through it. Therefore, the first cooling element 11 will not cool or dehumidify the low-humidity fresh air, and the second heating element 12 will not heat the low-humidity fresh air.

[0074] Specifically, when the processing system is in ventilation mode, the temperature regulating medium inside the liquefied heating element 34 stops circulating, the temperature of the temperature regulating medium inside the liquefied heating element 34 is almost the same as the temperature of the low-humidity fresh air flowing through it, the liquefied heating element 34 will not heat the low-humidity fresh air, and the second temperature regulating element 35 will not heat the low-temperature exhaust air.

[0075] Specifically, the second cooling element 21 no longer circulates the low-temperature temperature regulating medium 3, and the second cooling element 21 will not cool or dehumidify the low-humidity fresh air.

[0076] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0077] The processing system of this utility model includes a first temperature regulating element 31, a first heating element 41, a drying unit 5, a liquefaction heating element 34, and a first solution heat exchanger 51. When the processing system is in dehumidification mode, when the fresh air with high humidity flows through the first temperature regulating element 31, the temperature regulating medium inside the first temperature regulating element 31 vaporizes and absorbs heat to cool and dehumidify the fresh air, forming low-humidity fresh air. Then, the fresh air flowing out of the first temperature regulating element 31 flows through the liquefaction heating element 34 for heating, and the heated fresh air flowing out of the liquefaction heating element 34 flows into the drying unit 5. The air exchange area of ​​the drying unit 5 forms high-temperature exhaust air. The high-temperature exhaust air flowing out of the drying unit 5 then flows through the first solution heat exchanger 51 and exchanges heat with the heat exchange liquid inside the first solution heat exchanger 51. The heat exchange liquid then exchanges heat with the low-temperature liquid 2 outside the first solution heat exchanger 51, so that the heat of the high-temperature exhaust air is transferred to the low-temperature liquid 2 through the heat exchange liquid, causing the low-temperature liquid 2 to be heated to form high-temperature liquid 1. The high-temperature liquid 1 is used to enter the heating channel of the heater so that the heater outputs high-temperature air to heat and dry the workpiece. When the processing system is in ventilation mode, when the low-humidity fresh air flows through the first temperature regulating element 31, the first temperature regulating element 31 heats the low-humidity fresh air. Then, the fresh air flowing out of the first temperature regulating element 31 flows through the first heating element 41 for heating. The low-humidity fresh air flowing out of the first heating element 41 passes through the air exchange area of ​​the drying unit 5 to form exhaust air, and then the high-temperature exhaust air flows into the first solution heat exchanger 51. Therefore, regardless of whether the processing system of this utility model is in dehumidification mode or ventilation mode, it can utilize the first solution heat exchanger 51 to recover heat from the high-temperature exhaust air, thereby heating the low-temperature liquid 2 to form a high-temperature liquid 1. The high-temperature liquid 1 can serve as the heat energy source for the heater, so that the heat energy source for the heater does not solely rely on boiler hot water, greatly saving the energy required to dry the parts to be dried. In addition, when the processing system is in dehumidification mode, the first temperature regulating element 31 replaces the rotary dehumidifier to cool and dehumidify the fresh air, which can greatly save the energy required to cool and dehumidify the fresh air. As a result, the processing system of this utility model has low operating energy consumption, significantly reduces the operating cost of the processing system, and improves the economy of the processing system.

Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0080] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0081] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0082] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0083] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
