Description

Technical Field

[0001] The present invention relates to the technical field of grain bin dehumidification, and specifically to a water-cooled dehumidification and temperature control device for prefabricated metal grain bins. Background Art

[0002] A prefabricated metal grain bin is a modern grain storage facility. All components are processed in a factory and can be assembled at a designated site. The main components of these devices include steel plates, support structures, ventilation systems, monitoring equipment, and safety devices. Prefabricated metal grain bins are suitable for various scales of grain storage needs, such as warehouses, farms, and rural households. Corresponding ventilation, cooling, dehumidification, and other equipment can be configured according to the type, quantity, and storage conditions of the stored grain. During the storage process, the optimal environment for grain storage is a relative humidity maintained below 60% and a temperature controlled below 15°C, rather than absolute dryness. Among them, the optimal humidity required for paddy rice is between 25% and 60%. In order to keep the grain in an optimal humidity and temperature environment, a dehumidifier is used to absorb external air, dry the air to a certain extent, and then transport it into the grain bin, so that the air inside the prefabricated grain bin continuously circulates with the external air.

[0003] However, prefabricated grain bins are generally outdoors, so the dehumidifier is also installed outdoors. Existing dehumidifiers are generally condensation dehumidifiers, which mainly dry the air by condensing it through an evaporator. For example, an air purifier with an air energy dehumidification function disclosed in CN105066266A controls the operation of a heating device and a dehydration device through a controller. Humid air enters from the air inlet of the housing, passes through the water absorption film of the dehydration device and the water absorption film on the fan blade, and the water absorption film absorbs the moisture in the humid air. The humid air after being absorbed by the water absorption film enters the evaporator, and the evaporator is used for condensation dehumidification. The air after condensation dehumidification by the evaporator is discharged through the radiator and the exhaust port. However, when the evaporator condenses and dries the air, it is easily affected by the external environment. When it is rainy in winter, the temperature of the air is relatively low, and the condensation effect of the evaporator becomes poor, thus greatly reducing the effect of the dehumidifier.

[0004] Therefore, a water-cooled dehumidification and temperature control device for prefabricated metal grain bins is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a water-cooled dehumidification and temperature control device for prefabricated metal granaries. In order to solve the problem that in rainy weather in winter, the external air temperature is relatively low, and the water vapor in the air is not easily condensed, resulting in poor condensation effect of the evaporator and poor dehumidification effect. By heating and condensing and drying the inhaled air twice inside, the dehumidification effect is improved, thus solving the problem of poor dehumidification effect caused by the difficulty of condensing the moisture in the air due to the low air temperature in rainy winter. And during the second dehumidification, the condensed water on the heat exchange tubes is cleaned to avoid the growth of bacteria and affect the quality of the discharged air.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A water-cooled dehumidification and temperature control device for a prefabricated metal granary, which is used in cooperation with the prefabricated metal granary, includes a housing and a fan. An air inlet is provided on the front side of the housing. It further includes a connecting shell, a water storage component, a heating component, a drying component, a preheating component and a sealing component. The connecting shell is connected to the housing and communicates with the air inlet. The preheating component, the drying component and the heating component are all connected inside the connecting shell. The drying component includes a partition plate, which is connected to the connecting shell. The partition plate divides the drying component and the heating component into two left and right chambers, and the cross-sections of the four chambers are in a cross shape. The water storage component is arranged inside the housing and communicates with the drying component. The sealing component is connected to the connecting shell and is located above the heating component and the drying component. The preheating component preheats the air inhaled by the fan. The heated air enters the left chamber of the drying component for dehumidification, then enters the left chamber of the heating component for heating, then enters the right chamber of the drying component from above through the sealing component and blows off the condensed water in the right chamber of the drying component. Finally, the dried air enters the right chamber of the heating component for heating and is discharged into the prefabricated metal granary.

[0008] Since this device is placed outdoors, different from the dehumidifier placed indoors, when the indoor dehumidifier dehumidifies, it inhales and discharges the indoor air and then inhales it again, dehumidifying in a cyclic manner. When the dehumidification in the first inhalation does not reach the set value, since it is discharged indoors, it can be inhaled again for dehumidification. However, when dehumidifying an assembled grain bin, when dehumidifying the inhaled air, if the dehumidification does not reach the specified humidity, it is directly discharged into the interior of the grain bin. Therefore, when dehumidifying the assembled grain bin, the humidity of the discharged air must meet the set value, and it will not be like indoor dehumidification, where when the set value is not reached, the discharged air can be inhaled again for secondary or multiple dehumidifications. Therefore, in the above solution, by drying the inhaled air twice, the dryness of the air is improved. In the existing drying technology, the moisture in the air can be dried to a maximum of between 40% and 60%. However, this just meets the best storage humidity of paddy rice, so there will be no situation of over-drying. At the same time, before the second dehumidification, it will be heated by the heating component, thus avoiding the situation where in winter, due to the low air temperature, the moisture in the air is difficult to condense, resulting in poor dehumidification effect.

[0009] Preferably, the drying component further includes a vibrating plate, an evaporation tube, a fixed shell, an upper air inlet, a first sliding groove, a first moving plate, and a water outlet. The fixed shell is connected inside the connection shell. The partition is connected to the middle of the fixed shell, and the lower side and the front side are respectively perpendicular to the bottom of the connection shell and the front air inlet. A plurality of the vibrating plates are connected inside the fixed shell. The two ends of the evaporation tube are respectively connected to the left and right sides of the fixed shell and penetrate through a plurality of vibrating plates. The upper air inlet is opened on the upper side of the fixed shell and penetrates through the upper side of the connection shell. The first sliding groove is opened on the inner wall of the fixed shell and is located in front of the evaporation tube. The first moving plate is connected to the first sliding groove. The water outlet is opened at the bottom of the fixed shell, and the water outlet is connected to the water storage component.

[0010] In the above solution, the drying component is divided into two equal parts with equal left and right spaces by the partition. One is the main drying chamber, and the other is the auxiliary drying chamber. The just-entered gas is blocked by the first moving plate and first enters the main drying chamber. After drying, it enters the heating component for heating up, and then is discharged from the heating component and enters the auxiliary drying chamber through the upper air inlet for dehumidification and drying again, thereby improving the dehumidification effect and avoiding the situation where in rainy weather in winter, due to the low air temperature, the moisture in the air is difficult to condense out, resulting in poor dehumidification effect. Also, because of the heating by the heating component, the moisture in the air is more easily condensed, further improving the dehumidification effect.

[0011] Preferably, a plurality of the vibrating plates are perpendicular to each other, parallel to the front air inlet, and perpendicular to the upper air inlet. A circulation hole is opened in front of the vibrating plate.

[0012] In the above solution, since the vibrating plate is parallel to the forward air inlet, air only enters the main drying chamber through the circulation holes, thereby reducing the air flow rate in the main drying chamber, increasing the residence time of air in the main drying chamber, and improving the drying effect. Since it is perpendicular to the upper air inlet, the air flow direction of the air entering the auxiliary drying chamber through the upper air inlet is parallel to the vibrating plate. Therefore, when the air flows in the auxiliary drying chamber, the water droplets on the evaporation tube and the vibrating plate can be blown off and enter the water storage tank through the water outlet, avoiding the growth of bacteria due to the long-term residual water droplets on the vibrating plate and the evaporation tube, and also avoiding the water droplets covering the evaporation tube, preventing the air from directly contacting the evaporation tube and affecting the condensation effect.

[0013] Preferably, the rear end of the partition extends into the heating assembly. The heating assembly includes a condensation tube, a support plate, an upper air outlet, a third chute, and a second moving plate. Both ends of the condensation tube are connected to both sides of the inner wall of the connection shell. The support plate is connected inside the connection shell, and the condensation tube is perpendicular to the support plate. The third chute is opened on the inner wall of the connection shell and is located at the rear end of the condensation tube. The second moving plate is connected to the third chute. The condensation tube is connected to the preheating assembly. The upper air outlet is opened above the connection shell.

[0014] In the above solution, by extending the partition into the heating assembly, the heating assembly is divided into two equal parts with equal left and right spaces. One is the main heating chamber, and the other is the auxiliary heating chamber. The main heating chamber is communicated with the main drying chamber, the auxiliary heating chamber is communicated with the auxiliary drying chamber, and the auxiliary drying chamber is communicated with the main heating chamber through a sealing assembly. After being dried in the main drying chamber, the air first enters the main heating chamber, and the air entering the inside is heated by the condensation tube. Under the restriction of the second moving plate, the heated gas enters the auxiliary drying chamber through the upper air outlet. Then, the air coming out of the auxiliary drying chamber enters the auxiliary heating chamber and is discharged from the auxiliary heating chamber. Since the upper air outlet is located at the top and the density of hot air is less than that of cold air, the air that is first heated enters the auxiliary drying chamber for secondary drying first, so that the gas for secondary drying is fully heated. The moisture inside the heated air is more easily condensed out, further improving the drying effect.

[0015] Preferably, the sealing assembly includes a sealing shell, a second chute, a first gear, a sliding plate, and a first motor. The sealing shell is connected to the upper side of the connection shell and covers the upper air inlet and the upper air outlet. The second chute is formed on the inner wall of the sealing shell. The two sliding plates are slidably connected to the second chute, and tooth teeth are provided on the corresponding surfaces of the two sliding plates. The first gear is connected between the two sliding plates and meshes with the tooth teeth. The output end of the first motor is connected to the first gear. The rear end of the partition extends into the heating assembly. A power assembly is connected inside the partition. The power assembly includes a rotating shaft, a second gear, and a second motor. The rotating shaft is connected inside the partition. The second gear is connected to the front and rear ends of the rotating shaft. The second motor is connected to the rear end of the rotating shaft.

[0016] In the above solution, the upper air inlet of the main drying chamber and the upper air outlet of the auxiliary heating chamber are sealed by the sliding plate, so that air flows in the order of the main drying chamber, the main heating chamber, the auxiliary drying chamber, and the auxiliary heating chamber. The first motor and the second motor rotate synchronously to control the movement of the sliding plate, the first moving plate, and the second moving plate, change the sealing positions of the upper air inlet and the upper air outlet, as well as the air inlet position of the drying assembly and the air outlet position of the heating assembly, so as to interchange the relationship between the main drying chamber and the auxiliary drying chamber, and interchange the relationship between the main heating chamber and the auxiliary heating chamber. Because the moisture condensed in the main drying chamber is more than that in the auxiliary drying chamber, through the interchange of the main and auxiliary relationships, during the second dehumidification, the flowing air flow is used to clean the auxiliary drying chamber that was the main drying chamber before, so as to clean the two drying chambers alternately, and blow the water droplets in the two drying chambers into the water storage tank, thus avoiding the main drying chamber being always in a wet state, resulting in the growth of bacteria inside and then affecting the quality of the entering air.

[0017] Preferably, the sliding plate, the first moving plate, and the second moving plate have the same length, and the length and width of the sliding plate are both greater than the width and length of the upper air inlet and the upper air outlet.

[0018] In the above solution, when the sliding plate, the first moving plate, and the second moving plate move by the rotation of the first gear and the second gear, the sliding plate, the first moving plate, and the second moving plate can move synchronously, avoiding the air leaking from the heating assembly in advance due to the misalignment of the positions of the sliding plate, the first moving plate, and the second moving plate, which affects the dehumidification effect.

[0019] Preferably, the preheating assembly includes a heat exchange tube. The heat exchange tube is connected inside the connection shell and is connected to the water storage assembly.

[0020] In the above solution, the entering gas is heated by the heat exchange tube, avoiding the decrease of the condensation effect due to the low temperature of the gas in winter, and at the same time cooling the coolant inside the heat exchange tube to improve the cooling effect of the coolant.

[0021] Preferably, the water storage assembly includes a water storage tank, an exhaust pipe, a discharge port, and a through groove. The water storage tank is connected to the bottom of the inner wall of the housing. The exhaust pipe is connected to the upper side of the outer wall of the water storage tank and communicates with the outside of the housing. The discharge port is opened at the top of the water storage tank and communicates with the water outlet. The through groove is opened in the middle of the water storage tank. The heat exchange tube is connected to the inside of the through groove.

[0022] In the above solution, the water storage tank is used to receive the water discharged by the drying assembly, so as to facilitate the collection of condensed water. The heat exchange tube passes through the through groove, and the condensed water in the water storage tank is used to cool the heat exchange tube, achieving the effect of water cooling, thereby improving the cooling effect on the heat exchange tube. At the same time, the cooling water in the water storage tank is heated and evaporated by the heat exchange tube, and the evaporated water vapor is discharged from the exhaust pipe, thus avoiding the accumulation of condensed water inside and discharging it in the form of water vapor. Compared with directly discharging in the form of liquid, it avoids the surrounding environment from being in a humid state, thereby increasing the humidity of the surrounding air.

[0023] Preferably, the water storage assembly further includes a floating block, which is slidably connected to the discharge port, and the cross section of the floating block is set to a funnel shape.

[0024] In the above solution, the floating block is used to block the discharge port, thereby avoiding the complete evaporation of the water inside and losing the water cooling effect.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. By providing a partition and a drying assembly, the drying assembly is divided into an auxiliary drying chamber and a main drying chamber by the partition. The air first enters the main drying chamber in a direction parallel to the connecting shell. At this time, under the restriction of the vibrating piece, the air only enters the main drying chamber through the circulation holes, thereby reducing the air flow rate in the main drying chamber and increasing the residence time of the air in the main drying chamber, so that the air entering from the outside can be fully dried, thereby improving the drying effect. After the first drying, the air enters the heating assembly and flows into the auxiliary drying chamber from the heating assembly. At this time, the air flows in a direction perpendicular to the connecting shell. At this time, the air flow direction in the auxiliary drying chamber is parallel to the vibrating piece, and the water droplets on the evaporation tube and the vibrating piece can be blown into the water storage tank, avoiding the growth of bacteria due to the long-term residual water droplets on the vibrating piece and the evaporation tube, and also avoiding the water droplets covering the evaporation tube, preventing the air from directly contacting the evaporation tube and affecting the condensation effect.

[0027] 2. By providing a through groove, the condensing tube passes through the through groove and is connected to the evaporation tube, and is cooled by the condensed water in the water tank, thereby increasing the cooling effect of the condensing tube. At the same time, the cooling water in the water storage tank is heated and evaporated by the heat exchange tube, and the evaporated water vapor is discharged from the exhaust pipe, thus avoiding the accumulation of condensed water inside.

[0028] 3. By setting up a heating component, the heating component is divided into an auxiliary heating chamber and a main heating chamber by a partition board. The air dried in the main drying chamber first enters the main heating chamber, and the heated gas enters the auxiliary drying chamber from the upper air outlet. Since the upper air outlet is located at the top and the density of hot air is less than that of cold air, the air that is heated first enters the auxiliary drying chamber for secondary drying. As a result, the gas for secondary drying is fully heated, and the moisture inside the heated air is more easily condensed out, further improving the drying effect.

[0029] 4. By setting up a sealing component and a power component, the slide plate in the sealing component is controlled by the power component to change the sealing position. At the same time, the first moving plate and the second moving plate are controlled by the power component to change the shielding positions of the drying component and the heating component. Thus, the conversion between the main heating chamber and the auxiliary heating chamber, as well as the switching between the main drying chamber and the auxiliary drying chamber, are achieved. By changing the flow direction of air between each chamber, the condensed water in the auxiliary drying chamber that was previously the main drying chamber is cleared, thereby avoiding the situation where the condensation in the main drying chamber cannot be cleared in time, resulting in water droplets covering the evaporation tube and preventing the air from directly contacting the evaporation tube, which affects the condensation effect. At the same time, the growth of bacteria is also avoided, thereby improving the intake air quality. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention, and in combination with the working state, make its structural features more detailed. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1 to 10 , the present invention provides a water-cooled dehumidifying and temperature control device for a prefabricated metal granary, and the technical solution is as follows:

[0043] A water-cooled dehumidifying and temperature control device for a prefabricated metal granary, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 and Figure 10, used in conjunction with the prefabricated metal granary 1, including a housing 2 and a fan 3. An air inlet 201 is provided on the front side of the housing 2. It further includes a connecting shell 4, a water storage component 5, a heating component 6, a drying component 7, a preheating component 8, and a sealing component 9. The connecting shell 4 is connected to the inner wall of the housing 2 and is in communication with the air inlet 201. The preheating component 8, the drying component 7, and the heating component 6 are all connected inside the connecting shell 4. And the drying component 7 is located behind the preheating component 8, and the heating component 6 is located behind the drying component 7. The drying component 7 includes a partition 701. The partition 701 is connected to the connecting shell 4. The partition 701 divides the drying component 7 and the heating component 6 into two left and right chambers, and the upper cross-sections of the four chambers are in a cross shape. The water storage component 5 is arranged inside the housing 2 and is in communication with the drying component 7. The sealing component 9 is connected to the connecting shell 4 and is located above the heating component 6 and the drying component 7, and is in communication with the heating component 6 and the drying component 7. The preheating component 8 preheats the air inhaled by the fan 3. The heated air enters the left chamber of the drying component 7 for dehumidification, then enters the left chamber of the heating component 6 for heating, and then enters the right chamber of the drying component 7 from above through the sealing component 9, and blows off the condensed water in the right chamber of the drying component 7, so that the condensed water can flow into the water storage component 5 faster, avoiding the growth of bacteria caused by the long-term wet environment in the right chamber of the drying component 7, which affects the air quality. Finally, the dried air enters the right chamber of the heating component 6 for heating and is discharged into the prefabricated metal granary 1.

[0044] As an implementation manner of the present invention, refer to Figure 4 , Figure 5 and Figure 6, the drying component 7 further includes a vibration plate 702, an evaporation tube 703, a fixed shell 704, an upper air inlet 705, a first chute 706, a first moving plate 707, and a water outlet 708. The fixed shell 704 is connected inside the connection shell 4. The partition plate 701 is connected to the middle of the fixed shell 704, and the lower side and the front side are respectively perpendicular to the bottom of the connection shell 4 and the front air inlet 201, dividing the drying component 7 into two equal parts with equal left and right spaces. One of them is the main drying chamber 15, and the other is the auxiliary drying chamber 13. A plurality of the vibration plates 702 are connected inside the fixed shell 704. The two ends of the evaporation tube 703 are respectively connected to the left and right sides of the fixed shell 704 and penetrate through a plurality of vibration plates 702. The upper air inlet 705 is opened on the upper side of the fixed shell 704 and penetrates through the upper side of the connection shell 4. The first chute 706 is opened on the inner wall of the fixed shell 704 and is located in front of the evaporation tube 703. The first moving plate 707 is connected to the first chute 706. The side blocked by the first moving plate 707 is the auxiliary drying chamber 13, and the unblocked side is the main drying chamber 15. The newly entered gas is blocked by the first moving plate 707 and first enters the main drying chamber 15. After drying is completed, it enters the heating component 6 for heating up, and then is discharged from the heating component 6, enters the auxiliary drying chamber 13 through the upper air inlet 705, and undergoes two cycles of drying, thereby improving the dehumidification effect, avoiding the situation of poor drying effect in rainy weather in winter. Also, because of the heating by the heating component 6, the moisture in the air is more easily condensed, further improving the dehumidification effect. The water outlet 708 is opened at the bottom of the fixed shell 704. The water outlet 708 is connected to the water storage component 5. The condensed moisture in the air will gather at the bottom of the fixed shell 704 and be discharged into the water storage tank 501 through the water outlet 708.

[0045] As an implementation manner of the present invention, referring to Figure 4 and Figure 5 , a plurality of the vibration plates 702 are perpendicular to each other. Therefore, air only enters the main drying chamber 15 through the circulation holes 709, thereby reducing the flow rate of the air in the main drying chamber 15, increasing the residence time of the air in the main drying chamber 15, and thus improving the drying effect. And it is parallel to the front air inlet 201 and perpendicular to the upper air inlet 705. So the air flow direction of the air entering the auxiliary drying chamber 13 through the upper air inlet 705 is parallel to the vibration plates 702. Therefore, when the air flows in the auxiliary drying chamber 13, the water droplets on the evaporation tube 703 and the vibration plates 702 can be blown off and enter the water storage tank 501 through the water outlet 708, avoiding the breeding of bacteria due to the long-term residual water droplets on the vibration plates 702 and the evaporation tube 703. The circulation holes 709 are opened in front of the vibration plates 702.

[0046] As an implementation manner of the present invention, referring to Figure 4 , Figure 5 and Figure 6, the rear end of the partition plate 701 extends into the heating component 6, thereby dividing the heating component 6 into two equal parts with equal left and right spaces. One is the main heating chamber 14, and the other is the auxiliary heating chamber 12. The main heating chamber 14 is communicated with the main drying chamber 15, and the auxiliary heating chamber 12 is communicated with the auxiliary drying chamber 13. The air dried in the main drying chamber 15 first enters the main heating chamber 14. The heating component 6 includes a condensing pipe 601, a support plate 602, an upper air outlet 603, a third chute 604 and a second moving plate 605. The two ends of the condensing pipe 601 are respectively connected to both sides of the inner wall of the connection shell 4. The support plate 602 is connected inside the connection shell 4. The condensing pipe 601 and the support plate 602 are perpendicular to each other. The air entering the inside is heated by the condensing pipe 601. The third chute 604 is opened on the inner wall of the connection shell 4 and is located at the rear end of the condensing pipe 601. The second moving plate 605 is connected to the third chute 604. Among them, the part blocked by the second moving plate 605 is the main heating chamber 14, and the unblocked part is the auxiliary heating chamber 12. Under the restriction of the second moving plate 605, the heated gas enters the auxiliary drying chamber 13 from the upper air outlet 603. Then the air coming out of the auxiliary drying chamber 13 enters the auxiliary heating chamber 12 and is discharged from the auxiliary heating chamber 12. Because the upper air outlet 603 is arranged at the top, and because the density of hot air is less than that of cold air, the air that is heated first enters the auxiliary drying chamber 13 for secondary drying, so that the gas for secondary drying is fully heated. The moisture inside the heated air is more easily condensed out, further improving the drying effect. The condensing pipe 601 is connected to the preheating component 8. The upper air outlet 603 is opened above the connection shell 4.

[0047] As an embodiment of the present invention, referring to Figure 4 and Figure 6, the sealing assembly 9 includes a sealing housing 901, a second chute 902, a first gear 903, a sliding plate 904, and a first motor 905. The sealing housing 901 is connected to the upper side of the connecting housing 4 and covers the upper air inlet 705 and the upper air outlet 603. The second chute 902 is opened on the inner wall of the sealing housing 901. The two sliding plates 904 are slidably connected to the second chute 902, and tooth teeth are provided on the corresponding surfaces of the two sliding plates 904. The upper air inlet 705 of the main drying chamber 15 and the upper air outlet 603 of the auxiliary heating chamber 12 are sealed by the sliding plates 904, so that air flows in the order of the main drying chamber 15, the main heating chamber 14, the auxiliary drying chamber 13, and the auxiliary heating chamber 12. The first gear 903 is connected between the two sliding plates 904 and meshes with the tooth teeth. The output end of the first motor 905 is connected to the first gear 903. The rear end of the partition plate 701 extends into the heating assembly 6. A power assembly 10 is connected inside the partition plate 701. The power assembly 10 includes a rotating shaft 1001, a second gear 1002, and a second motor 1003. The rotating shaft 1001 is connected inside the partition plate 701. The second gear 1002 is connected to the front and rear ends of the rotating shaft 1001. The second motor 1003 is connected to the rear end of the rotating shaft 1001. The first motor 905 and the second motor 1003 rotate synchronously to drive the first gear 903 and the second gear 1002 to rotate. The first gear 903 and the second gear 1002 mesh with the tooth teeth to control the movement of the sliding plate 904, the first moving plate 707, and the second moving plate 605, thereby changing the sealing positions of the sliding plate 904 with the upper air inlet 705 and the upper air outlet 603, as well as the air inlet positions of the first moving plate 707 and the drying assembly 7, and the air outlet positions of the second moving plate 605 and the heating assembly 6, so as to mutually transform between the main drying chamber 15 and the auxiliary drying chamber 13, and mutually transform the relationship between the main heating chamber 14 and the auxiliary heating chamber 12, so as to alternately clean the two drying chambers, blow the water droplets in the two drying chambers into the water storage tank 501, thereby avoiding the drying chambers being in a humid state, resulting in the growth of bacteria inside and further affecting the quality of the incoming air.

[0048] As an embodiment of the present invention, referring to Figure 4 , Figure 5 and Figure 6 , the sliding plate 904, the first moving plate 707, and the second moving plate 605 have the same length. Because the rotation speeds of the first gear 903 and the second gear 1002 are the same, when controlling the movement of the sliding plate 904, the first moving plate 707, and the second moving plate 605, the moving distances are also the same, so as to realize the synchronous movement of the sliding plate 904, the first moving plate 707, and the second moving plate 605. The length and width of the sliding plate 904 are both greater than the width and length of the upper air inlet 705 and the upper air outlet 603.

[0049] As an embodiment of the present invention, referring toFigure 5 and Figure 8 The preheating component 8 includes a heat exchange tube 801 which is connected inside the connection shell 4. The heat exchange tube 801 is used to heat the incoming gas, avoiding the decrease in the condensation effect due to the low gas temperature in winter. At the same time, it also cools the coolant inside the heat exchange tube 801, improving the cooling effect of the coolant. The heat exchange tube 801 is connected to the water storage component 5.

[0050] As an implementation manner of the present invention, referring to Figure 8 The water storage component 5 includes a water storage tank 501, an exhaust pipe 502, a discharge port 503 and a through groove 504. The water storage tank 501 is connected to the bottom of the inner wall of the outer shell 2, and the water storage tank 501 is used to receive the water discharged by the drying component 7, thus facilitating the collection of condensed water. The exhaust pipe 502 is connected to the upper side of the outer wall of the water storage tank 501 and communicates with the outside of the outer shell 2. The evaporated condensed water is discharged from the exhaust pipe 502 and blown away by the outside gas. Compared with direct discharge, it avoids the surrounding environment from being in a humid state, thereby increasing the humidity of the surrounding air. The discharge port 503 is opened at the top of the water storage tank 501 and communicates with the water outlet 708. The through groove 504 is opened in the middle of the water storage tank 501, and the heat exchange tube 801 is connected inside the through groove 504, so that the heat exchange tube 801 passes through the through groove 504. The condensed water in the water storage tank 501 is used to cool the heat exchange tube 801 to achieve the water cooling effect, thereby improving the cooling effect on the heat exchange tube 801. At the same time, the heat exchange tube 801 heats and evaporates the cooling water in the water storage tank 501, and the evaporated water vapor is discharged from the exhaust pipe 502, thus avoiding the accumulation of condensed water inside.

[0051] As an implementation manner of the present invention, referring to Figure 3 、 Figure 5 and Figure 8 The water storage component 5 further includes a floating block 505 which is slidably connected to the discharge port 503. The cross-section of the floating block 505 is set to be funnel-shaped. When the water level is low, the floating block 505 blocks the discharge port 503, thus avoiding the complete evaporation of the internal water and losing the water cooling effect.

[0052] Working principle: Start the fan 3, suck the outside air from the front air inlet 201 into the inside of the outer shell 2 and enter the connection shell 4, then sequentially pass through the preheating component 8, the drying component 7 and the heating component 6, and finally discharge from the outlet of the fan 3. When passing through the preheating component 8, the air is preheated to avoid the decrease in the condensation effect of the moisture in the air due to the low air temperature, thereby improving the dehumidification effect. When the air passes through the drying component 7, the drying component 7 condenses and dries the air and discharges the condensed water into the water storage tank 501. When the air enters the heating component 6, the heating component 6 heats the air.

[0053] In order to avoid the problem of poor dehumidification effect caused by low air temperature in rainy weather in winter, the inside of the drying component 7 is divided into two identical chambers by a partition plate 701, and air enters the two chambers in sequence for dehumidification, so as to increase the dehumidification times and improve the dehumidification effect. And it is heated by the heating component 6 before the second dehumidification, further improving the dehumidification effect;

[0054] Specifically: the drying component 7 is divided into two chambers by a partition plate 701. The chamber on the air inlet side blocked by the first moving plate 707 is the auxiliary drying chamber 13, and the unblocked one is the main drying chamber 15. Since the partition plate 701 extends into the heating component 6, the heating component 6 is also divided into two chambers. The chamber on the air outlet side blocked by the second moving plate 605 is the main heating chamber 14, and the unblocked one is the auxiliary heating chamber 12. When the gas enters the inside of the connection shell 4, blocked by the first moving plate 707, the air enters the main drying chamber 15, is dried by the main drying chamber 15 and then enters the main heating chamber 14. Since the air outlet side of the main heating chamber 14 is blocked, the air enters the inside of the sealing shell 901 through the upper air outlet 603. Since the upper air inlet 705 of the main drying chamber 15 and the upper air outlet 603 of the auxiliary heating chamber 12 are blocked by the sliding plate 904, the air enters the auxiliary drying chamber 13 through the upper air inlet 705 above the auxiliary drying chamber 13 for secondary drying, thus improving the dehumidification effect of the air. The air dried for the second time enters the auxiliary heating chamber 12 and finally is discharged from the auxiliary heating chamber 12 and enters the assembled metal granary 1 through the fan 3.

The scope of the present invention is defined by the appended claims and their equivalents.
