The advantage of this type of industrial dryer is fast heating speed, but the energy consumption is relatively high. Some industrial dryers are heat pump dryers. The temperature adjustment range of this type of heat pump dryer is narrow and the adjustment flexibility is poor, which limits the application scope of industrial dryers and cannot meet the production needs of some products. Utility Model Content

[0009] A regulating passage, one end of which is connected to a side of the first condenser away from the air outlet, and the other end of which is connected to the inlet. The regulating passage includes a regulating solenoid valve and a second condenser. The regulating solenoid valve can control the on and off of the regulating passage. The second condenser is located outside the target area.
[0010] Specifically, on the one hand, a group of heat pump structures is formed by a compressor, an evaporator and a first condenser, and the first condenser is used to output heat to the target area, which can not only make the temperature stability of the target area higher and the temperature adjustment range of the target area wider, but also reduce the energy consumption of temperature control; on the other hand, by setting the adjustment passage, the adjustment passage and the first condenser form a series structure, and the opening and closing of the adjustment solenoid valve is used to control the on-off of the adjustment passage, so that the adjustment passage can selectively speed up the refrigerant flow rate in the first condenser, so as to reduce the heat exchange amount of the refrigerant at the position of the first condenser, thereby realizing the output heat regulation of the first condenser and the temperature control of the target area, and effectively ensuring the continuous and stable operation of the system.
[0011] As an implementation manner, the regulating solenoid valve is arranged on a side of the second condenser close to the gas outlet end.
[0012] Specifically, by arranging the regulating solenoid valve upstream of the refrigerant delivery direction of the second condenser, the regulating solenoid valve can isolate the second condenser from the compressor, completely restricting the refrigerant from entering the second condenser, avoiding the refrigerant from exchanging heat in the second condenser, and thus making the refrigerant discharged from the compressor exchange heat only with the first condenser, so that the heat of the refrigerant is fully utilized by the first condenser in stages, thereby helping to improve the efficiency of the first condenser in outputting heat to the target area.
[0013] As an implementation manner, the regulating passage further includes a regulating one-way valve, and the regulating one-way valve is arranged on a side of the second condenser away from the gas outlet end.
[0014] Specifically, by arranging the one-way valve on the side of the second condenser away from the outlet end, the refrigerant can be prevented from reversely entering the second condenser from the end of the regulating passage away from the regulating solenoid valve, thereby achieving effective protection of the second condenser and preventing the refrigerant from exchanging heat at the second condenser position when the regulating solenoid valve is not opened.
[0015] As an implementation manner, the second condenser is thermally connected to the evaporator, and the heat of the second condenser can be transferred to the evaporator.
[0016] Specifically, by thermally connecting the second condenser to the evaporator, heat can be provided to the evaporator, thereby improving the evaporation efficiency of the evaporator for the refrigerant, thereby helping the refrigerant to evaporate more fully and reducing the risk of liquid hammer in the compressor.

[0018] Specifically, by arranging the second condenser and the evaporator in parallel, the air can immediately enter the evaporator after absorbing heat and heating up in the second condenser, so that the air can transfer heat to the evaporator more fully, thereby improving the heat conduction efficiency between the second condenser and the evaporator, thereby helping to improve the evaporation efficiency of the evaporator for the refrigerant.

[0020] Specifically, by setting the temperature sensor on the first condenser, the temperature sensor can be used to monitor the temperature of the target area. Furthermore, when the temperature sensor detects that the temperature of the target area reaches the preset temperature, the system can control the compressor to stop working or control the regulating solenoid valve to open, and use the regulating passage to speed up the refrigerant flow rate in the first condenser, thereby reducing the output heat of the first condenser to achieve cooling of the target area; when the temperature sensor detects that the temperature of the target area is lower than the preset temperature, the system can control the compressor to start working or control the regulating solenoid valve to close, thereby closing the regulating passage, slowing down the refrigerant flow rate in the first condenser, so that the refrigerant can exchange heat more fully at the first condenser position, increase the output heat of the first condenser, and achieve heating of the target area.
[0021] As an embodiment, the heat supply path includes two first condensers, and the two first condensers are arranged in parallel.
[0022] Specifically, by arranging two first condensers in parallel, the temperature control device can perform heating control on two different positions of the target area at the same time, thereby making the temperature of different positions of the target area more uniform.
[0023] As an embodiment, the heating passage further includes a heating expansion valve, which is arranged on a side of the first condenser close to the inlet end, and the regulating passage is connected to a pipeline between the first condenser and the heating expansion valve.
[0024] Specifically, the opening and closing of the regulating passage has an impact on the flow rate and pressure of the heating passage. By arranging the heating expansion valve on the side of the first condenser close to the inlet end, the heating expansion valve can achieve a buffering effect, thereby preventing the flow rate and pressure changes of the heating passage caused by the opening and closing of the regulating passage from impacting the compressor, thereby helping to improve the working stability of the overall temperature control device.
[0025] On the other hand, a drying system is provided, which includes a box and any one of the temperature control devices described above, wherein the first condenser is disposed in the box.
[0026] Specifically, by arranging the first condenser in the box, the first condenser is utilized to stably and reliably deliver heat to the workpieces in the box, thereby effectively improving the drying efficiency of the workpieces.
[0027] As an embodiment, the drying system includes two conveying lines, two target areas are arranged inside the box, the two conveying lines correspond to the two target areas one by one, and the first condenser is arranged in at least one of the target areas.
[0028] Specifically, the temperature control device forms an independent temperature control module, which can be directly used in different target areas. According to the actual needs of the drying system, the temperature control devices can be respectively set in different target areas of the drying system, thereby achieving effective temperature control at different positions of the drying system.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0046] The present application embodiment provides a temperature control device, such as Figure 1 As shown, the temperature control device includes a compressor 1, an evaporator 2, a heat supply passage 3 and a regulating passage 4, the compressor 1 includes an air inlet end 11 and an air outlet end 12; the evaporator 2 includes an inlet end 21 and an outlet end 22, and the outlet end 22 is connected to the air inlet end 11; one end of the heat supply passage 3 is connected to the air outlet end 12, and the other end of the heat supply passage 3 is connected to the inlet end 21, the heat supply passage 3 includes a first condenser 31, and the first condenser 31 is used to output heat to the target area 101; one end of the regulating passage 4 is connected to a side of the first condenser 31 away from the air outlet end 12, and the other end of the regulating passage 4 is connected to the inlet end 21, the regulating passage 4 includes a regulating solenoid valve 41 and a second condenser 42, the regulating solenoid valve 41 can control the on and off of the regulating passage 4, and the second condenser 42 is located outside the target area 101.
[0047] Specifically, on the one hand, a heat pump structure is formed by the compressor 1, the evaporator 2 and the first condenser 31, and the first condenser 31 is used to output heat to the target area 101, which can not only make the temperature stability of the target area 101 higher and the temperature adjustment range of the target area 101 wider, but also reduce the energy consumption of temperature control; on the other hand, by setting the adjustment passage 4, the adjustment passage 4 and the first condenser 31 form a series structure, and the opening and closing of the adjustment passage 4 is controlled by the opening and closing of the adjustment solenoid valve 41, so that the adjustment passage 4 can selectively speed up the refrigerant flow rate in the first condenser 31, so as to reduce the heat exchange amount of the refrigerant at the position of the first condenser 31, thereby realizing the output heat regulation of the first condenser 31 and the temperature control of the target area 101, and effectively ensuring the continuous and stable operation of the system. Further, when the output heat of the first condenser 31 reaches a preset value, the regulating solenoid valve 41 is switched to an open state, so that the regulating passage 4 is turned on. At this time, the regulating passage 4 can speed up the flow rate of the refrigerant in the first condenser 31, thereby reducing the heat exchange amount of the refrigerant at the position of the first condenser 31, so that the output heat of the first condenser 31 no longer continues to rise; when the output heat of the first condenser 31 is lower than the preset value, the regulating solenoid valve 41 is switched to a closed state, so that the regulating passage 4 is disconnected, and the refrigerant no longer flows through the regulating passage 4, so that the flow rate of the refrigerant in the first condenser 31 is reduced, thereby increasing the heat exchange amount of the refrigerant at the position of the first condenser 31, and thereby increasing the output heat of the first condenser 31. Overall, by adjusting the opening and closing of the solenoid valve 41, the dynamic balance of the output heat of the first condenser 31 is achieved, so that the temperature control device can accurately and stably control the temperature of the target area 101.
[0048] During the specific implementation process, the heat pump structure formed by the compressor 1, evaporator 2 and first condenser 31 is used to control the temperature of the target area 101, so that the temperature of the target area 101 can be adjusted between 40 degrees and 85 degrees, thereby enabling the target area 101 to meet the temperature requirements in the production process of more different products, which helps to improve the versatility of the temperature control device.
[0049] In one embodiment, if Figure 1 As shown, the regulating solenoid valve 41 is arranged on a side of the second condenser 42 close to the gas outlet end 12 .
[0050] Specifically, by setting the regulating solenoid valve 41 upstream of the refrigerant delivery direction of the second condenser 42, the regulating solenoid valve 41 can isolate the second condenser 42 from the compressor 1, completely restricting the refrigerant from entering the second condenser 42, and avoiding the refrigerant from exchanging heat with the second condenser 42. As a result, the refrigerant discharged from the compressor 1 only exchanges heat with the first condenser 31, and the heat of the refrigerant is fully utilized by the first condenser 31 in stages, thereby helping to improve the efficiency of the first condenser 31 in outputting heat to the target area 101.
[0051] Of course, in other embodiments, the regulating solenoid valve 41 can also be arranged on the side of the second condenser 42 away from the air outlet end 12, that is, the regulating solenoid valve 41 is arranged downstream of the refrigerant delivery direction of the second condenser 42. In this state, the second condenser 42 is connected to the compressor 1 and the first condenser 31. Although this design will allow a small amount of refrigerant to enter the second condenser 42, this design as a whole can also achieve on-off control of the regulating passage 4. Furthermore, this design can also limit the large amount of refrigerant entering the second condenser 42 and exchanging heat, thereby realizing the flow rate adjustment of the refrigerant at the first condenser 31 position and realizing the control of the heat exchange amount of the refrigerant at the first condenser 31 position.
[0052] In one embodiment, if Figure 1 As shown, the regulating passage 4 further includes a regulating one-way valve 43 , and the regulating one-way valve 43 is arranged on a side of the second condenser 42 away from the gas outlet end 12 .
[0053] Specifically, by setting a one-way valve on the side of the second condenser 42 away from the air outlet end 12, the refrigerant can be prevented from reversely entering the second condenser 42 from the end of the regulating passage 4 away from the regulating solenoid valve 41, thereby achieving effective protection for the second condenser 42 and preventing the refrigerant from exchanging heat at the second condenser 42 when the regulating solenoid valve 41 is not opened.
[0054] In one embodiment, the second condenser 42 is thermally connected to the evaporator 2 , and the heat of the second condenser 42 can be transferred to the evaporator 2 .
[0055] Specifically, by thermally connecting the second condenser 42 to the evaporator 2 , heat can be provided to the evaporator 2 , thereby improving the evaporation efficiency of the evaporator 2 for the refrigerant, thereby helping the refrigerant to evaporate more fully and reducing the risk of liquid hammer in the compressor 1 .
[0056] In one embodiment, the second condenser 42 and the evaporator 2 are arranged in parallel, and the second condenser 42 is located on the air inlet side of the evaporator 2 .
[0057] Specifically, by arranging the second condenser 42 and the evaporator 2 in parallel, the air that has absorbed heat and heated up in the second condenser 42 can immediately enter the evaporator 2, so that the air can more fully transfer heat to the evaporator 2, thereby improving the thermal conductivity between the second condenser 42 and the evaporator 2, thereby helping to improve the evaporation efficiency of the evaporator 2 for the refrigerant.
[0058] In the specific implementation process, the evaporator 2 is correspondingly provided with a first fan, and the first fan is used to drive air through the evaporator 2. The second condenser 42 is correspondingly provided with a second fan, and the second fan is used to drive air through the second condenser 42. When the second condenser 42 and the evaporator 2 are arranged in parallel, the first fan and the second fan can share a fan, and the fan is arranged on the side of the evaporator 2 away from the second condenser 42. The fan can form a negative pressure on the side of the evaporator 2 away from the second condenser 42, so that the air on the side of the second condenser 42 away from the evaporator 2 is attracted and passes through the second condenser 42 and the evaporator 2 in sequence, thereby realizing efficient and reliable air flow and heat exchange. Of course, in other embodiments, when the second condenser 42 and the evaporator 2 are arranged in parallel, it can also be designed as follows: the first fan is arranged on the side of the evaporator 2 away from the second condenser 42, and the second fan is arranged between the evaporator 2 and the second condenser 42.
[0059] In one embodiment, a heat conductor is provided between the second condenser 42 and the evaporator 2, one end of the heat conductor is connected to the second condenser 42, and the other end of the heat conductor is connected to the evaporator 2. The heat conductor directly transfers the heat of the second condenser 42 to the evaporator 2. This design has high thermal conductivity efficiency.
[0060] In one embodiment, the temperature control device further includes a temperature sensor, which is disposed on the first condenser 31 and is used to detect the temperature of the target area 101 .
[0061] Specifically, by setting a temperature sensor on the first condenser 31, the temperature sensor can be used to monitor the temperature of the target area 101. Further, when the temperature sensor detects that the temperature of the target area 101 reaches the preset temperature, the system can control the compressor 1 to stop working or control the regulating solenoid valve 41 to open, and use the regulating passage 4 to speed up the refrigerant flow rate in the first condenser 31, thereby reducing the output heat of the first condenser 31 and achieving the cooling of the target area 101; when the temperature sensor detects that the temperature of the target area 101 is lower than the preset temperature, the system can control the compressor 1 to start working or control the regulating solenoid valve 41 to close, thereby closing the regulating passage 4, slowing down the refrigerant flow rate in the first condenser 31, so that the refrigerant can exchange heat more fully at the first condenser 31, increase the output heat of the first condenser 31, and achieve the heating of the target area 101.
[0062] In one embodiment, the temperature control device further includes a controller, which is electrically connected to the regulating solenoid valve 41 and the temperature sensor so as to control the on-off of the regulating passage 4 as a whole.
[0063] In one embodiment, if Figure 1 As shown, the heat supply path 3 includes two first condensers 31, and the two first condensers 31 are arranged in parallel. Specifically, by arranging two parallel first condensers 31, the temperature control device can simultaneously perform heating control on two different positions of the target area 101, thereby making the temperature of different positions of the target area 101 more uniform.
[0064] In one embodiment, if Figure 1 As shown, the heating passage 3 also includes a heating expansion valve 32 , which is disposed on a side of the first condenser 31 close to the inlet end 21 , and the regulating passage 4 is connected to a pipeline between the first condenser 31 and the heating expansion valve 32 .
[0065] Specifically, the opening and closing of the regulating passage 4 has an impact on the flow rate and pressure of the heating passage 3. By arranging a heating expansion valve 32 on the side of the first condenser 31 close to the inlet end 21, the heating expansion valve 32 can achieve a buffering effect, thereby preventing the flow rate and pressure changes of the heating passage 3 caused by the opening and closing of the regulating passage 4 from impacting the compressor 1, thereby helping to improve the working stability of the overall temperature control device.
[0066] In one embodiment, the number of the heat supply paths 3 is two, and the two heat supply paths 3 are arranged in parallel. In a specific implementation, the first condensers 31 on the two different heat supply paths 3 can be arranged at different positions according to the requirements of the target area 101 .
[0067] In one embodiment, the two heat supply passages 3 share a heat supply expansion valve 32, that is, the two heat supply passages 3 converge into a main passage on the side away from the gas outlet 12, and the heat supply expansion valve 32 is arranged on the main passage. Of course, in other embodiments, it can also be designed that: an independent heat supply expansion valve 32 is arranged for each of the two heat supply passages 3.

[0069] Specifically, by setting up two parallel compressors 1, when the target area 101 needs to be heated up quickly, the two compressors 1 can be turned on at the same time to increase the flow rate of the refrigerant, thereby increasing the refrigerant flowing through the first condenser 31, thereby increasing the output heat of the first condenser 31; when the temperature of the target area 101 enters the dynamic equilibrium stage, the amount of refrigerant required by the first condenser 31 is small, and the temperature control device can turn off one of the compressors 1 and only use the other compressor to provide refrigerant to the first condenser 31, so as to maintain the first condenser 31 outputting heat to the target area 101.
[0070] In one embodiment, the air inlet end 11 and the air outlet end 12 of the compressor 1 are respectively provided with temperature detection components. These two sets of temperature detection components are used to monitor the return air temperature and the exhaust air temperature of the compressor 1, and to alarm when the return air temperature or the exhaust air temperature is abnormal, so as to ensure the effective operation of the compressor 1 and effectively maintain the service life of the compressor 1.

These two sets of pressure detection components are used to monitor the return air pressure and exhaust pressure of the compressor 1, and to alarm when the return air pressure or the exhaust pressure is abnormal, so as to ensure the effective operation of the compressor 1 and effectively maintain the service life of the compressor 1.
[0072] In another aspect, a drying system is provided, such as Figure 2 As shown, the drying system includes a box 100 and any of the above-mentioned temperature control devices, and the first condenser 31 is arranged in the box 100. Specifically, by arranging the first condenser 31 in the box 100, the first condenser 31 is used to stably and reliably transfer heat to the workpiece in the box 100, thereby effectively improving the drying efficiency of the workpiece. In the specific implementation process, the drying system can be applied to the production of the shoe industry.
[0073] In one embodiment, the drying system further includes a conveyor line. A target area 101 for drying the workpiece is provided inside the box 100 . The conveyor line runs through the box 100 , and the conveyor line can convey the workpiece to the target area 101 .
[0074] In one embodiment, if Figure 2 As shown, the drying system includes two conveying lines. Two target areas 101 are arranged inside the box 100. The two conveying lines correspond to the two target areas 101 one by one. A first condenser 31 is arranged in at least one target area 101.
[0075] Specifically, the temperature control device forms an independent temperature control module, which can be directly used in different target areas 101. According to the actual needs of the drying system, temperature control devices can be respectively set in different target areas 101 of the drying system, thereby achieving effective temperature control at different positions of the drying system.
[0076] Furthermore, the two conveyor lines are distributed up and down, and the two target areas 101 are also distributed up and down, and the upper target area 101 and the lower target area 101 are respectively connected to a temperature control device.
[0077] In one embodiment, each heating passage 3 includes two first condensers 31 , and the two first condensers 31 in the same heating passage 3 are respectively arranged on the left and right sides of the same conveying line to make the temperature of the target area 101 more uniform.
