Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] The application scenario of tent hospitals often leads to them being in a humid environment, and the Chinese herbal medicines stored in the hospital are prone to moisture. The existing Chinese herbal medicine drying device adopts a drum design, which is easy to cause damage to the Chinese herbal medicines and lead to the loss of effective ingredients, especially the dried Chinese herbal medicines are more prone to damage.

[0037] In view of this, the present invention provides a tent hospital drying device, including a drying component 100, a base component 200, a transfer component 300 and a storage rack 400, such as Figure 1 As shown, the drying component 100 is installed on the base component 200, and the base component 200 is used to drive the drying component 100 to swing in the vertical plane; the storage rack 400 is arranged in the transfer component 300, and the transfer component 300 drives the storage rack 400 to move in the vertical direction and drives the storage rack 400 to swing in the vertical plane; the dried Chinese herbal medicine pile can enter the storage rack 400 under the action of gravity for storage.

[0038] The following combination Figure 1-Figure 11 The structure and shape of the tent hospital drying device provided in this embodiment are described in detail:

[0039] In this embodiment, the pile of Chinese herbal medicines can be directly placed in the drying assembly 100 for drying, or a drying box can be used to store different Chinese herbal medicines separately. The drying box is conducive to the drying, transportation and storage of Chinese herbal medicines. Specifically, the drying box is a rectangular box with an open top made of a metal mesh or a high-temperature resistant plastic mesh, which is used to hold Chinese herbal medicines and allow hot air to pass through. High-temperature resistant plastics can be PPS, PPA, PEEK, etc. When using a metal mesh, care should be taken to avoid affecting the medicinal properties of the Chinese herbal medicines. Usually, one pile of Chinese herbal medicines corresponds to one drying box for drying, and horizontal partitions or vertical partitions can also be used to store multiple Chinese herbal medicines, and the partitions must be a mesh structure. The piles of Chinese herbal medicines mentioned in the following content refer to piles of Chinese herbal medicines that are directly stacked or piles of Chinese herbal medicines placed in a drying box.

[0040] In an optional solution of this embodiment, the drying assembly 100 includes a supporting plate 110, a pressing plate 120, a closing baffle 150, a lifting baffle 130 and a longitudinal partition 140. Figure 3 , Figure 6 As shown. The support plate 110 includes a U-shaped plate 111 and a lower flow channel plate 112. Figure 6As shown, the two ends of the U-shaped plate 111 along the length direction are the entrance and exit of the Chinese herbal medicine pile respectively, and the lower end is connected to the lower flow channel plate 112. A plurality of lifting baffles 130 are arranged along the length direction of the U-shaped plate 111 to block the Chinese herbal medicine pile or the drying box, and the longitudinal partition 140 is used to limit the moving direction of the Chinese herbal medicine pile and separate the Chinese herbal medicine pile to ensure the interval between the Chinese herbal medicine piles. Specifically, the lifting baffle 130 can be lifted to block the Chinese herbal medicine pile or allow the Chinese herbal medicine pile to pass smoothly. Through the lifting baffle 130 and the longitudinal partition 140, the incoming Chinese herbal medicine pile can be arranged in a rectangular array and kept at intervals to form a flow passage, which is convenient for the hot air flowing out of the Chinese herbal medicine pile to flow and be discharged. That is, the U-shaped plate 111, the two lifting baffles 130 and the two longitudinal partitions 140 form a receiving cavity with an upper opening, which is used to accommodate Chinese herbal medicine or a drying box for holding Chinese herbal medicine, and the adjacent receiving cavities are arranged at intervals to form a flow passage. It should be noted that, in order to prevent the lifting baffle 130 and the longitudinal partition 140 from affecting the hot air flowing out from the surroundings of the Chinese herbal medicine pile, the height of the lifting baffle 130 and the longitudinal partition 140 is much smaller than the height of the drying box or a mesh structure is adopted, that is, a plurality of through holes are opened on the lifting baffle 130 and the longitudinal partition 140 to facilitate air circulation. In addition, the lifting baffle 130 and the longitudinal partition 140 of the mesh structure can be surrounded by the supporting plate 110 to form a receiving cavity with an upper opening for storing the Chinese herbal medicine pile, and the pressing plate 120 is used to block the opening of the receiving cavity and contact with the Chinese herbal medicine. The lifting baffle 130 can be driven by an electric telescopic rod.

[0041] It should be noted that the drying box needs to be filled with Chinese herbal medicines to ensure that the Chinese herbal medicine pile is in contact with the pressing plate 120. Alternatively, a horizontal mesh plate can be placed in the drying box to separate different Chinese herbal medicines.

[0042] Furthermore, an air outlet 10 is provided at the bottom of the U-shaped plate 111, an air inlet 50 is provided on the lower flow channel plate 112, and a lower air duct 40 is provided on the side where the lower flow channel plate 112 and the U-shaped plate 111 are connected, and the lower air duct 40 is communicated with the air inlet 50, so that the hot air entering from the air inlet 50 is dispersed into multiple strands and blown out from the air outlet 10 to form dispersed wind, so that the hot air enters the Chinese herbal medicine pile from the lower surface of the Chinese herbal medicine pile, such as Figure 7 shown.

[0043] In this embodiment, the pressing plate 120 includes a contact plate 121 and an upper flow channel plate 122. Figure 4 , Figure 5As shown, the lower end of the upper flow channel plate 122 is connected to the contact plate 121, and an upper air duct 30 is provided on the side where the upper flow channel plate 122 is connected to the contact plate 121, and an air outlet 10 is provided on the contact plate 121, and the upper air duct 30 is connected to the air outlet 10. The upper flow channel plate 122 is also provided with an air inlet 50 and a return air outlet 20, and the air inlet 50 is connected to the upper air duct 30; the contact plate 121 is provided with a connecting port 60, and the connecting port 60 is connected to the return air outlet 20. The hot air enters from the air inlet 50 and passes through the upper air duct 30 to be dispersed into multiple strands to form dispersed wind, and then blows into the interior of the Chinese herbal medicine pile from the upper surface of the Chinese herbal medicine pile through the air outlet 10. After the hot air flows out from all sides of the Chinese herbal medicine pile, it is finally discharged through the connecting port 60 and the return air outlet 20 in sequence.

[0044] It should be noted that the air outlet 10 is located in the middle of the upper and lower surfaces of the Chinese herbal medicine pile to ensure that hot air is blown into the center of the Chinese herbal medicine pile and then flows around the Chinese herbal medicine pile to make the Chinese herbal medicine pile dry evenly.

[0045] In this embodiment, the closed baffle 150 is hinged to the U-shaped plate 111, and is used to close the entrance and exit of the Chinese herbal medicine pile at both ends of the U-shaped plate 111. The closed baffle 150, the pressing plate 120 and the supporting plate 110 form a rectangular closed space for drying the Chinese herbal medicine pile, and hot air enters from the air inlet 50 and is discharged from the return air outlet 20. Figure 5 As shown, grooves are provided around the contact plate 121 for installing a sealing ring so as to form a good seal between the contact plate 121 and the inner wall of the U-shaped plate 111 .

[0046] In an optional solution of this embodiment, the base assembly 200 includes a switch telescopic rod 210, a swing base plate 220, an adjustment base 230 and a swing telescopic rod 240. Figure 2 As shown. One end of the switch telescopic rod 210 is connected to the upper flow channel plate 122, and the other end is installed on the swing base plate 220.

[0047] In an optional solution of this embodiment, the storage rack 400 includes a load-bearing plate 410, a swing baffle 420, a main frame body 430 and a side baffle 440. Fig.10As shown. The main frame 430 includes an upper top plate, a lower bottom plate and supporting columns. The four supporting columns are arranged in a rectangular shape, and the two ends are connected to the upper top plate and the lower bottom plate respectively; multiple bearing plates 410 are arranged horizontally and arranged in the vertical direction, and are used to carry the piles of Chinese herbal medicines; the swing baffle 420 is installed below the bearing plate 410, and can swing in the vertical plane to block the piles of Chinese herbal medicines placed on the next layer of bearing plates 410; the side baffle 440 extends along the sliding direction of the piles of Chinese herbal medicines, and is used to separate the piles of Chinese herbal medicines to ensure the gap between the piles of Chinese herbal medicines for air circulation. When the piles of Chinese herbal medicines enter and exit, the storage rack 400 is tilted, and when the piles of Chinese herbal medicines enter, the swing baffles 420 swing to a vertical state in turn to block the piles of Chinese herbal medicines, and when the piles of Chinese herbal medicines leave the storage rack 400, the swing baffles 420 swing to a horizontal state in turn to release the piles of Chinese herbal medicines one by one. The lower end of the main frame 430 is also provided with a through transfer slot 70, which is convenient for forklifts and other tools to carry the storage rack 400. The swing baffle 420 can be driven by a motor to swing. The output shaft of the motor is coaxially arranged with the swing axis of the swing baffle 420. In order to provide power to the swing baffle 420, a battery is also arranged on the storage rack 400 to drive the motor. Through the layered design of the storage rack 400 and the blocking of the swing baffle 420, the pile of Chinese herbal medicines can be kept well ventilated. At the same time, the swing baffle 420 can ensure accurate access to the pile of Chinese herbal medicines, and prevent the pile of Chinese herbal medicines from leaving the storage rack 400 in large quantities and sticking to each other, which is convenient for subsequent use.

[0048] In an optional solution of this embodiment, the transfer assembly 300 is used to drive the storage rack 400 to move in the vertical direction and drive the storage rack 400 to swing in the vertical plane. Figure 2 , Figure 8 As shown, the transfer assembly 300 includes an angle adjustment unit 310 and a height adjustment unit 320. The angle adjustment unit 310 includes a lifting base 311, an angle adjustment telescopic rod 312 and a tray 313; the tray 313 is hinged to the lifting base 311 and is used to place the storage rack 400; one end of the angle adjustment telescopic rod 312 is installed on the lifting base 311, and the other end is hinged to the tray 313. Among them, the lifting base 311 includes a second bottom plate and a second hinge rod, the second hinge rod is vertically connected to the second bottom plate and hinged to the tray 313, and the angle adjustment telescopic rod 312 is installed on the second bottom plate. The tray 313 is tilted by the extension and contraction of the angle adjustment telescopic rod 312, thereby driving the storage rack 400 to tilt.

[0049] In this embodiment, the height adjustment unit 320 includes a lifting frame body 321, a driving wheel 322, a wire rope 323 and a guide wheel 324. The lifting frame body 321 includes a lifting bottom plate, a lifting top plate and a guide rod. The four guide rods are arranged in a rectangular shape, and the two ends are connected to the lifting bottom plate and the lifting top plate respectively; the lifting base 311 is installed on the lifting frame body 321 and is slidably connected to the lifting frame body 321. Specifically, a through hole is opened on the second bottom plate of the lifting base 311, and the guide rod is inserted into the through hole; the driving wheel 322 is installed on the lifting top plate, and the guide wheel 324 is installed on the second bottom plate. One end of the wire rope 323 is connected to the driving wheel 322, and the other end is connected to the lifting base 311 and guided by the guide wheel 324 to make the wire rope 323 become a vertical state to ensure stable force. The driving wheel 322 rotates around its own axis to wind the wire rope 323, thereby driving the lifting base 311 to rise and fall, and the driving wheel 322 can be driven by a motor. The guide wheel 324 includes an I-shaped wheel, a rotating shaft and a mounting frame. Fig. 9 As shown, a guide wheel 324 can be set on the lifting top plate, and the guide wheel 324 on the lifting top plate and the second bottom plate is set on a vertical straight line to ensure that the wire rope 323 is vertical, so as to avoid the wire rope 323 tilting due to the diameter change caused by the driving wheel 322 winding the wire rope 323, thereby causing the problem of unbalanced force. The driving wheel 322 winds or releases the wire rope 323 to drive the angle adjustment unit 310 to rise and fall, thereby moving the storage rack 400 to switch the carrier plate 410.

[0050] In the optional solution provided in this embodiment, the tent hospital drying device also includes a transition conveyor belt, which is arranged between the transfer assembly 300 and the drying assembly 100, and is used to transport the dried Chinese herbal medicine pile to the storage rack 400. Specifically, the transition conveyor belt is inclined to have the same inclination angle as the storage rack 400 and the drying assembly 100 to achieve a smooth transition from beginning to end. Similarly, a transition conveyor belt can also be arranged before the Chinese herbal medicine pile enters the drying assembly 100 for transition.

[0051] In the optional solution provided in this embodiment, the tent hospital drying device also includes a return air device, such as Fig.11As shown, the return air device includes a hot air blower 510, a first one-way valve 520, a hair dryer 530, a filter 540, a first humidity sensor 550, a first switch valve 560, a second switch valve 570, a second one-way valve 580 and a second humidity sensor 590 to form a hot air branch, an exhaust branch, a filter branch and a return air branch. Specifically, the hot air blower 510 and the first one-way valve 520 form a hot air branch, and the hot air blower 510 provides hot air to the drying component 100 to dry the pile of Chinese herbal medicines. After being output from the hot air blower 510, the hot air passes through the first one-way valve 520 and is divided into two paths to respectively input hot air to the upper and lower surfaces of the pile of Chinese herbal medicines; the second humidity sensor 590 and the second switch valve 570 form an exhaust branch, and the hot air is discharged from the return air port 20 after being output through the pile of Chinese herbal medicines. The exhausted hot air first passes through the first humidity sensor 550 to detect the humidity. If the humidity is high, the second switch valve 570 is opened to directly discharge the hot air; if the humidity is low, the second switch valve 570 is closed, so that the hot air passes through the second humidity sensor 590 and then passes through the filter branch and the return air branch to return to the drying component 100 to continue drying. Among them, the filter branch includes a first switch valve 560, a filter 540 and a first humidity sensor 550. The filter 540 is used to filter the moisture in the hot air. The first humidity sensor 550 is used to monitor the humidity of the hot air after passing through the filter 540 to determine whether the filter 540 needs to be replaced. In order to avoid downtime caused by replacing the filter 540, two parallel filter branches are set, and the two filter branches do not work at the same time. The return air branch includes a blower 530 and a second one-way valve 580. The hot air passes through the blower 530 and the second one-way valve 580 in sequence and returns to the drying component 100. At this time, the hot air blower 510 can stop working, so as to make full use of the existing hot air for drying and reduce energy consumption. At this time, the first one-way valve 520 can prevent the hot air from flowing back into the hot air blower 510, and the second one-way valve 580 can prevent the hot air blown out by the hot air blower 510 from entering the return air branch. The blower 530 is only used to drive the air flow without heating. In addition, the return air device also includes a temperature sensor for detecting the temperature of the hot air to determine whether the hot air can be used for drying.

[0052] That is, the return air device determines whether the hot air can be recycled by judging the temperature and humidity of the hot air flowing out of the Chinese herbal medicine pile, so as to reduce the energy consumption used for heating and make full use of the heat energy for drying. The filter 540 can reduce the humidity of the hot air to ensure the drying effect when recycled. In the early stage of drying, the hot air is discharged through the exhaust branch, and in the later stage of drying, the hot air is recycled through the filter branch.

[0053] In the optional solution of this embodiment, in order to improve the flexibility of the equipment, casters can be provided on the adjustment base 230 and the main frame 430 to facilitate the transfer of various components, and casters can also be provided on related components. It should be noted that casters with brakes should be selected.

[0054] The working process of the tent hospital drying device provided in this embodiment is as follows:

[0055] The base assembly 200 drives the drying assembly 100 to tilt so that the end of the drying assembly 100 close to the transfer assembly 300 is lower than the end away from the transfer assembly 300, and the switch telescopic rod 210 is extended to make the pressing plate 120 away from the supporting plate 110. At this time, the pile of Chinese herbal medicines slides into the supporting plate 110 under the action of gravity, and the lifting baffle 130 is raised to prevent the pile of Chinese herbal medicines from sliding out from the end of the supporting plate 110 close to the drying assembly 100. Each lifting baffle 130 is used to block a pile of Chinese herbal medicines so that the pile of Chinese herbal medicines maintains sufficient clearance.

[0056] When the drying component 100 is filled with the Chinese herbal medicine pile, the closed baffle 150 is closed, and then the switch telescopic rod 210 is retracted to make the pressing plate 120 descend, and the pressing plate 120 and the bottom of the supporting plate 110 seal the upper and lower sides of the Chinese herbal medicine pile, so that the hot air can only flow out from the surroundings of the Chinese herbal medicine pile. Then the base component 200 drives the drying component 100 to restore the drying component 100 to a horizontal state, and the hot air blower 510 blows in hot air for drying. After drying is completed, the switch telescopic rod 210 is extended to make the pressing plate 120 away from the supporting plate 110, so that the Chinese herbal medicine pile can move under the action of gravity.

[0057] The base assembly 200 drives the drying assembly 100 to tilt, and the lifting baffle 130 retracts to release the pile of Chinese herbal medicines, and the pile of Chinese herbal medicines enters the storage rack 400 for storage through the transition conveying assembly under the action of gravity.

[0058] When storing the pile of Chinese herbal medicines, the height adjustment unit 320 drives the angle adjustment unit 310 to move, and then drives the storage rack 400 to move. The angle adjustment unit 310 drives the storage rack 400 to tilt to facilitate the entry of the pile of Chinese herbal medicines. When in use, the bottom layer of the carrier plate 410 can be loaded first, and the storage rack 400 moves down to load each carrier plate 410, and the lifting baffles 130 are retracted one by one to allow the pile of Chinese herbal medicines to enter the storage rack 400 one by one. After being filled, the storage rack 400 can be moved away by a forklift and an empty storage rack 400 can be placed. It should be noted that this storage and access scheme is suitable for the transportation of Chinese herbal medicines and the centralized storage of the same kind of Chinese herbal medicines.

[0059] When taking out the Chinese herbal medicine pile, the storage rack 400 is placed in the transfer assembly 300, and the angle adjustment unit 310 drives the storage rack 400 to tilt so that the Chinese herbal medicine pile slides out under the action of gravity. At this time, the swing baffles 420 swing to a horizontal state one by one to release the Chinese herbal medicine piles one by one, so as to avoid the Chinese herbal medicine piles being close together and causing inconvenience in taking out.

[0060] The tent hospital drying device provided in this embodiment can dry the herbal medicines evenly without invading the interior of the herbal medicine pile or turning the herbal medicine pile over. After drying, the herbal medicine pile is moved by gravity without invasively grabbing or turning the herbal medicine pile over, thereby avoiding damage to the herbal medicines and the resulting loss of effective ingredients.
