[0010] Preferably, a temperature sensor is installed in the box.

[0011] Preferably, activated carbon is provided in the heater.

[0012] Preferably, a drain pipe is also included; a drain groove is provided on the lower side of the box body; a drain pipe is fixedly connected to the rear side of the box body; the drain groove is connected to the drain pipe; each connecting roller is hollow; a drain port is provided on each sliding plate; a water inlet is provided on each connecting roller, and each drain port is connected to the corresponding water inlet; the connecting rollers located at the bottom are connected to the drain groove.

Through this method, the drying efficiency in each drying area is maximized, the drying effect is guaranteed, and energy consumption is reduced; and because the bearing capacity of the spring is limited, when the weight of the drying material placed on the bearing plate is greater than the bearing capacity of the spring, the spring will directly contract and cause the sliding plate to drop directly. Therefore, workers can set the height of the limit ring in advance according to the height of the drying material to prevent the sliding plate from dropping directly due to the heavier drying material and squeezing the drying material on the next layer, causing damage to the material.

[0025] A temperature sensor is installed in the box 1, which monitors the temperature in the box 1 and then transmits the monitored temperature data to the controller 2 in real time. The controller 2 adjusts the operating state of the equipment in real time according to the received temperature data to maintain the stability of the temperature in the box 1, ensure that the temperature in the box 1 is always in the best working state, avoid energy waste, and thus achieve the purpose of saving energy.

[0026] Activated carbon is arranged in the heater 3, and the moisture in the air drawn into the box body 1 is adsorbed by the activated carbon, so as to reduce the moisture content in the box body 1 and improve the drying effect.

[0027] The working principle of the above embodiment is as follows: First, Figure 1 The view is the visual reference, where the side where the controller 2 is marked is the left side. First, the worker opens the door on the box body 1, and then puts the materials to be dried on the supporting plate 104. During this process, the worker can pull the supporting plate 104 forward to facilitate the worker to place the materials. After the materials are placed, the worker pushes the supporting plate 104 back, and then screws the first locking screw 10401 into the corresponding fixing groove 10105 to fix the supporting plate 104 to prevent the supporting plate 104 from slipping out and affecting the worker from placing other materials into other supporting plates 104. After all the materials to be dried are placed, the door on the box body 1 is closed, and the heater 3 and the circulating fan 4 are started by the controller 2. The external air is drawn into the heater 3 by the circulating fan 4, and the hot air heated by the heater 3 is sent into the box body 1 to dry the materials in the box body 1, and then the air is discharged from the box body 1. In this process, Figure 3As shown: after the hot air is blown out from the heater 3, it will enter the air inlet grooves 1001 on both sides of the box body 1 and enter between two adjacent sliding plates 101; the material on the supporting plate 104 is dried; then the gas will be discharged upward into the circulation fan 4 through the exhaust port 10102 and the exhaust groove 10501 in the middle of the sliding plate 101, and finally discharged from the box body 1; and during the drying process, the temperature sensor monitors the temperature inside the box body 1, and then transmits the monitored temperature data to the controller 2 in real time. The controller 2 adjusts the operating state of the equipment in real time according to the received temperature data to maintain the stability of the temperature inside the box body 1, ensure that the temperature inside the box body 1 is always in the best working state, avoid energy waste, and thus achieve the purpose of saving energy; activated carbon is arranged in the heater 3, and the moisture in the air drawn into the box body 1 is adsorbed by the activated carbon, so as to reduce the moisture content in the box body 1 and improve the drying effect.

[0028] However, in order to facilitate workers to place the materials to be dried, the existing hot air circulation bellows usually have large gaps between the compartments, which results in a large internal space of the bellows. As a result, during the heating process, it takes a long time for the hot air to fill the entire bellows, so that the materials in the bellows can be evenly heated. This not only prolongs the drying time, but also increases energy consumption, making the entire drying process time-consuming and laborious. Therefore, during the drying process, the controller 2 controls the telescopic part of the electric push rod 5 to be pushed downward, and then the electric push rod 5 pushes the pressure plate 105 to move downward, and then the pressure plate 105 will squeeze each connecting roller 103 downward, and then Figure 5 and Figure 6 As shown, the springs 106 between the adjacent connecting rollers 103 will be compressed and contracted, and then the connecting rollers 103 will drive the connecting block and the sliding plate 101 to move downward, so that the distance between the upper and lower sliding plates 101 is reduced, and due to the interaction force between the springs 106, each spring 106 will be relatively uniformly contracted, so that the distance between the upper and lower adjacent sliding plates 101 will be relatively uniformly reduced, and finally present Fig.10 In the state shown, the hot air will only enter between two adjacent sliding plates 101 through the air inlet slot 1001 to dry the materials on the carrying plate 104, thereby reducing the drying space of the equipment, greatly improving the drying efficiency, reducing energy consumption, and saving costs; but at this time there will be a large space on the upper side of the pressure plate 105, and the gas will enter the upper side of the pressure plate 105, while there is no heated object on the upper side of the pressure plate 105, so the space on the upper side of the pressure plate 105 is divided by the sealing curtain 108; and then during the drying process, the hot air will not enter the upper side of the pressure plate 105, avoiding the waste of hot air; After drying, ambient air at room temperature is drawn into the box body 1 through the circulating fan 4 to cool the inside of the box body 1. At this time, the telescopic part of the electric push rod 5 is controlled by the controller 2 to move upward and reset, thereby releasing the squeezing of the pressure plate 105 and the spring 106. At this time, the spring 106 stretches and resets, thereby driving each sliding plate 101 to move upward and reset. Then the space between two adjacent sliding plates 101 becomes larger, which is convenient for cooling air to enter the box body 1, thereby improving the subsequent heat dissipation, cooling speed and cooling effect of the box body 1, and making it convenient for workers to put materials into the carrying plate 104. Wheels 6 are fixedly connected to the lower side of the box body 1, and the staff can push the box body 1 to move and push the box body 1 to the material cleaning area, so that the workers can directly put the materials after cleaning into the box body 1 for drying.

[0029] Furthermore, when the hot air enters the area between the adjacent sliding plates 101 through the air inlet slot 1001, the air permeable curtain 102 between the sliding plates 101 blocks the hot air intake, so that most of the hot air enters the lower side of the supporting plate 104 through the air inlet 10101 and flows upward through the filter screen on the lower side of the supporting plate 104, so that the hot air flows upward from the lower side of the material to evenly dry the material; at the same time, when the prior art is drying, the water vapor generated in the drying process will flow upward and enter the drying space of the upper layer, causing the upper layer of material to be moistened by the water vapor, affecting the overall drying effect and causing uneven drying. Figure 7 As shown: only the exhaust port 10102 in the middle is connected between two adjacent sliding plates 101, so water vapor can only flow upward through the exhaust port 10102 in the middle. When water vapor enters the exhaust port 10102 and flows upward, the gas is guided by the guide plate 107 so that the gas can only flow upward through the drainage groove 10701 inclined toward the middle and enter the upper space, thereby preventing water vapor from entering the upper drying space during the upward flow and wetting the material in the upper layer, which affects the overall drying effect of the material.

[0030] Furthermore, when it is necessary to dry materials of different sizes, due to the interaction force between the springs 106, the distance between the upper and lower two adjacent sliding plates 101 will be relatively uniformly reduced, so the reduced distance between the upper and lower two adjacent sliding plates 101 can only accommodate the largest material; resulting in a larger space between the other upper and lower adjacent sliding plates 101, affecting the overall drying effect. Therefore, in the initial state, the wedge surface 20301 does not contact the wedge block 204. At this time, the limit ring 202 is slidably connected to the connecting rod 201. Therefore, the worker can pull the limit ring 202 upward according to the height of the dried material, so that the lower surface of the limit ring 202 is consistent with the highest height of the dried material, and then the worker twists the second locking screw 203 backward to make the wedge surface 20301 move backward, squeeze the wedge block 204, and then squeeze the wedge block 204 against the corresponding connecting roller 103, so that the wedge block 204 is in contact with the surface of the connecting roller 103 The contact between the wedge block 204 and the surface of the connecting roller 103 increases, thereby increasing the friction between the wedge block 204 and the surface of the connecting roller 103, thereby locking the limit ring 202; then, when the sliding plate 101 of the upper layer moves downward and contacts the limit ring 202, it is limited by the limit ring 202, and the sliding plate can no longer move downward. In this way, the distance between the upper and lower adjacent sliding plates 101 is only one limit ring 202 higher than the height of the drying material. In this way, the drying efficiency in each drying area is maximized, the drying effect is guaranteed, and the energy consumption is reduced. Moreover, because the bearing capacity of the spring 106 is limited, when the weight of the drying material placed on the bearing plate 104 is greater than the bearing capacity of the spring 106, the spring 106 will directly contract, causing the sliding plate 101 to directly drop. Therefore, the worker can set the height of the limit ring 202 in advance according to the height of the drying material, so as to prevent the sliding plate 101 from being directly dropped due to the heavier drying material, squeezing the drying material of the next layer, and causing damage to the material.

[0031] Example 2 On the basis of Example 1, Figure 2-Figure 6 As shown, it also includes a drain pipe 205; a drain groove 1002 is opened on the lower side of the box body 1; the drain pipe 205 is fixedly connected to the rear side of the box body 1; the drain groove 1002 is connected to the drain pipe 205; each connecting roller 103 is hollow; each sliding plate 101 is provided with a drain port 10103; each connecting roller 103 is provided with a water inlet 10302, and each drain port 10103 is connected to the corresponding water inlet 10302; the connecting rollers 103 located at the bottom are connected to the drain groove 1002.

[0032] A filter is provided at each drain outlet 10103.

[0033] The working principle of the above embodiment is as follows: When placing the dried material on the carrying plate 104 as described in Example 1: When encountering some materials with high water content, the staff will drain the materials first to reduce the water content of the materials and then put the materials into the box 1 for drying in order to improve the drying efficiency, reduce the drying energy consumption and save costs. However, during the draining process, the materials are easily contaminated by the outside world, which affects the quality of the dried materials. Figure 2-Figure 6 As shown: After the items are cleaned, workers can directly put the materials on the supporting plate 104, and then the moisture in the materials will flow into the upper surface of the sliding plate 101 through the filter on the lower side of the supporting plate 104, and then be discharged into the connecting roller 103 through the corresponding drain port 10103 and the water inlet 10302, and then flow downward through the lowest connecting roller 103 and be discharged into the drainage trough 1002, and finally be discharged from the box 1 through the drain pipe 205, and then directly drain the materials with high water content in the box 1 to avoid external contamination of the materials and ensure the quality of the materials after drying; further, the drain port 10103 is provided with a filter to prevent some small materials or impurities from falling into the upper surface of the sliding plate 101 through the filter on the lower side of the supporting plate 104, and then flowing into the connecting roller 103 and being washed away.

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