[0024] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.
[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the internal structure of the independent dehumidification open-loop heat pump tobacco flue-curing system provided by the present invention; Figure 2 for Figure 1 The structural schematic diagram of the adsorption and dehumidification mechanism shown; Figure 3 for Figure 2 A partial enlarged view of the middle A; Figure 4 for Figure 1 The structural schematic diagram of the fresh air intake mechanism shown; Figure 5 for Figure 1The isometric structural diagram of the independent dehumidification open-loop heat pump flue-cured tobacco system shown. The independent dehumidification open-loop heat pump flue-cured tobacco system comprises: an oven 8; a partition 7, wherein the oven 8 is fixedly connected with the partition 7, and the partition 7 divides the oven 8 into a return air bin 6 and a fresh air bin 9; a main unit 4, wherein the outer surface of the oven 8 is fixedly connected with the main unit 4 with an evaporator; a condenser 5, wherein the fresh air bin 9 is installed with the condenser 5, and the condenser 5 is connected with the evaporator in the main unit 4; a fresh air intake mechanism 2, wherein the fresh air intake mechanism 2 is connected with the oven 8, and the fresh air intake mechanism 2 is interconnected with the bottom of the fresh air bin 9; an adsorption dehumidification mechanism 1, wherein the adsorption dehumidification mechanism 1 is installed in the fresh air bin 9; an exhaust pipe 9a, wherein the outer surface of the oven 8 is fixedly connected with the exhaust pipe 9a interconnected with the fresh air bin 9, and the exhaust pipe 9a is located at the bottom of the fresh air bin 9; a drainage hose 3, wherein the lower surface of the oven 8 is fixedly connected with the drainage hose 3 interconnected with the inside thereof.
[0026] In the specific implementation process, Figure 1 As shown, the adsorption and dehumidification mechanism 1 includes a side panel 11 and a soft water-absorbing layer 14. The two opposite inner walls of the fresh air bin 9 are fixedly connected with the side panels 11, and a soft water-absorbing layer 14 for adsorption and dehumidification is detachably connected between the two side panels 11.
[0027] It should be noted that when the device is in use, fresh air enters the fresh air bin 9 through the fresh air intake mechanism 2, and the soft water-absorbing layer 14 can adsorb the water vapor in the dehumidified and separated circulating air, thereby reducing the relative humidity of the circulating air. At this time, the dry circulating air is heated by the condenser 5, which will greatly reduce the heating energy (because the heat capacity of dry air is small, while the heat capacity of water vapor is large). Therefore, the dry air after dehumidification will inevitably reduce the energy demand and the load demand of the circulating air, thereby achieving the purpose of reducing the power configuration and realizing system energy saving.
[0028] refer to Figure 2 and Figure 3 As shown, the adsorption and dehumidification mechanism 1 also includes a mounting plate 12, a hydraulic cylinder 13, a lightweight top mesh plate 15, a bottom mesh plate 16 and a baffle 17, the top of the side plate 11 is fixedly connected with the baffle 17, and the bottom mesh plate 16 is provided between the two side plates 11, wherein the soft water-absorbing layer 14 is fixedly connected to the upper surface of the bottom mesh plate 16, and the upper surface of the soft water-absorbing layer 14 is fixedly connected with the lightweight top mesh plate 15, and the upper surface of the lightweight top mesh plate 15 is in contact with the baffle 17; the inner wall of the fresh air bin 9 is fixedly connected with the mounting plate 12, and the output end of the mounting plate 12 is fixedly connected with a support plate, and the support plate is in contact with the lower surface of the bottom mesh plate 16.
[0029] It should be noted that the hydraulic cylinder 13 contracts, at which time the support plate connected to the output end of the hydraulic cylinder 13 no longer contacts the bottom mesh plate 16, that is, no longer supports the bottom mesh plate 16. At this time, the soft water-absorbing layer 14, the lightweight top mesh plate 15 and the bottom mesh plate 16 can be taken out from between the two side plates 11, which is conducive to the cleaning and replacement of the soft water-absorbing layer 14 and reduces the difficulty of using the device.
[0030] It should also be noted that the bottom mesh plate 16 can block the airflow, thereby reducing the flow rate of the airflow through the soft water-absorbing layer 14, increasing the contact time between the soft water-absorbing layer 14 and the airflow, thereby improving the dehumidification effect of the airflow;
[0031] It should also be noted that as the use time goes by, when the soft water-absorbing layer 14 gradually absorbs water and approaches saturation, the hydraulic cylinder 13 can extend to squeeze the soft water-absorbing layer 14, so that the water vapor absorbed in the soft water-absorbing layer 14 gathers into water droplets and drips onto the inner bottom wall of the oven 8. The water droplets are discharged through the drainage hose 3, so that the soft water-absorbing layer 14 can be regenerated, thereby ensuring the long-term stability of the moisture absorption effect of the soft water-absorbing layer 14.
[0032] refer to Figure 3 As shown, the adsorption and dehumidification mechanism 1 also includes a spring 18 and a groove 19 . The lower surface of the baffle 17 is connected with the spring 18 , and the bottom of the spring 18 is inserted into the groove 19 opened on the upper surface of the lightweight top mesh plate 15 .
[0033] It should be noted that when the soft water-absorbing layer 14 is in normal use, the spring 18 is compressed, and the soft water-absorbing layer 14 is stably placed between the baffle 17 and the support plate under the action of the elastic restoring force of the spring 18; and when the hydraulic cylinder 13 is extended, the support plate gently squeezes the bottom mesh plate 16 under the action of the spring 18, reducing the probability of damage to the bottom mesh plate 16;
[0034] It should also be noted that the groove 19 can limit the spring 18 .
[0035] refer to Figure 2 As shown, the side of the bottom mesh plate 16 is fixedly connected to a limiting block, and the opposite surfaces of the two side plates 11 are provided with limiting grooves with lower ends opened, and the limiting blocks are slidably connected in the limiting grooves.
[0036] It should be noted that the limiting blocks and the limiting grooves play a limiting role, so that the movement of the bottom mesh plate 16 is more stable, and the installation of the bottom mesh plate 16 is more stable.
[0037] refer to Figure 1 As shown, the soft water-absorbing layer 14 is a water-absorbing sponge or a sponge-type water-absorbing filler.
[0038] It should be noted that the material of the soft water-absorbing layer 14 is described, and the material of the soft water-absorbing layer 14 is not limited thereto, and may also be other soft water-absorbing materials.
[0039] refer to Figure 1 and Figure 4 As shown, the fresh air intake mechanism 2 includes an L-shaped air intake pipe 21 and a top baffle 22. The bottom of the fresh air bin 9 is provided with an L-shaped air intake pipe 21 opening upward. The horizontal section of the L-shaped air intake pipe 21 passes through the oven 8 and is fixedly connected to the oven 8. There is a top baffle 22 above the vertical section of the L-shaped air intake pipe 21, and the top baffle 22 is connected to the L-shaped air intake pipe 21 through a connecting rod.
[0040] It should be noted that there is a certain gap between the top baffle 22 and the upper opening of the L-shaped air inlet pipe 21, so that fresh air can enter the fresh air bin 9 through the L-shaped air inlet pipe 21, and the top baffle 22 can prevent water droplets from falling into the L-shaped air inlet pipe 21.
[0041] refer to Figure 1 As shown, the inner bottom wall of the oven 8 is inclined toward the drain hose 3 .
[0042] It should be noted that this is conducive to the dripping water drops to gather and enter the drainage hose 3.
[0043] The working principle of the independent dehumidification open-loop heat pump tobacco flue-curing system provided by the present invention is as follows:
[0044] When the device is in use, fresh air enters the fresh air bin 9 through the fresh air intake mechanism 2, and the soft water-absorbing layer 14 can absorb and dehumidify the water vapor in the circulating air, thereby reducing the relative humidity of the circulating air. At this time, the dry circulating air is heated by the condenser 5, which will greatly reduce the heating energy (because the heat capacity of dry air is small, while the heat capacity of water vapor is large). Therefore, the dry air after dehumidification will inevitably reduce the energy demand and the load demand of the circulating air, thereby achieving the purpose of reducing the power configuration and realizing system energy saving; and the airflow can be blocked by the bottom mesh plate 16, thereby reducing the flow rate of the airflow through the soft water-absorbing layer 14, increasing the contact time between the soft water-absorbing layer 14 and the airflow, thereby improving the dehumidification effect on the airflow.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
