[0036] Specifically, as Figure 1 and Figure 2As shown, a control panel 2 is fixedly connected to the middle of the front surface of the housing 1. Feeding ports 3 are provided in the middle of both the left and right ends of the housing 1. Sealing doors 5 are hinged to the middle of both the left and right ends of the housing 1 and are located below the fixing frames 4. Among them, an air curtain is fixedly installed at the inner top of the feeding port 3, which can prevent the hot air inside the housing 1 from overflowing. The control panel 2 is electrically connected to the fan 16, the heating pipe 22, the electric cylinder 25, and the temperature sensor. Through the control panel 2, the fan 16, the heating pipe 22, and the electric cylinder 25 can be controlled to make the temperature during drying reach the optimum.

[0037] Specifically, as Figure 1 and Figure 2 shown, fixing frames 4 are fixedly connected below both of the two feeding ports 3. A mesh conveyor belt 6 passing through the feeding ports 3 is installed between the two fixing frames 4. The mesh conveyor belt 6 is located below the temperature control mechanism. Through the mesh conveyor belt 6, shoes can be conveyed into the housing 1, and at the same time, the mesh conveyor belt 6 can allow the air in the drying chamber 8 to pass through and enter the air collecting frame 10.

[0038] Specifically, as Figures 2-4 shown, the air collecting frame 10 is located below the mesh conveyor belt 6. A plurality of through holes 11 evenly distributed at equal intervals are provided in the middle of the bottom end of the air collecting frame 10.

The two enclosing plates 12, the air collecting frame 10, and the housing 1 can enclose a closed chamber, so that the gas above can be collected into this chamber.

[0040] Specifically, as Figures 2-4 shown, sliding rail grooves 14 are fixedly connected to the middle parts of the sides of the two enclosing plates 12 close to each other. An activated carbon filter 15 is slidably connected between the two sliding rail grooves 14, and the activated carbon filter 15 corresponds to the sealing door 5. The activated carbon filter 15 can dehumidify and adsorb the recovered gas, making the circulated gas dry and odorless.

[0041] Specifically, as Figure 3 and Figure 4As shown in the figure, two fans 16 are fixedly connected to the inner bottom end of the circulation chamber 9. The two fans 16 are respectively located at the right end of the front side of the front baffle 12 and the left end of the rear side of the rear baffle 12.

At the same time, the air pressure in the chamber formed by the two baffles 12 becomes lower. Under the action of the air pressure, the gas in the drying chamber 8 enters the chamber through the mesh conveyor belt 6 and the air collecting frame 10.

[0042] Specifically, as Figures 3-4 shown, the heating mechanism includes a heating box 21. The heating box 21 is fixedly connected to the upper surface of the fixing plate 7 and is located between the L-shaped plate 19 and the housing 1. A plurality of heating tubes 22 are fixedly installed inside the heating box 21 and are distributed at equal intervals. The top of the heating box 21 is fixedly connected to four exhaust pipes 23 through a four-way pipe. One ends of the four exhaust pipes 23 away from the heating box 21 penetrate through the vertical plate 20 and are connected to the temperature control mechanism; under the action of the fan 16, the filtered gas can be sent into the heating box 21 through the air outlet pipe 18. Under the control of the control panel 2, the heating tubes 22 can heat the gas to the set temperature, and then send it between the two L-shaped plates 19 through the exhaust pipes 23.

[0043] Specifically, as Figures 2-3 shown, the temperature control mechanism includes a movable plate 24. The movable plate 24 is slidably connected between the two vertical plates 20. Electric cylinders 25 are fixedly connected between the upper surfaces of the two ends of the movable plate 24 and the inner bottom wall of the housing 1; the telescopic movement of the electric cylinders 25 can be controlled through the control panel 2. The electric cylinders 25 drive the movable plate 24 to move up and down. Among them, the up and down movement of the movable plate 24 can drive the exhaust pipes 23 to move up and down, so that the distance between the exhaust pipes 23 and the shoes can be adjusted. At the same time, in cooperation with the air output of the fan 16, the height of the exhaust pipes 23 can be adjusted according to different shoes, so that the drying temperature can be controlled.

[0044] Specifically, as Figures 2-3 shown, eight mounting holes are provided in the middle of the movable plate 24. Corresponding exhaust pipes 23 are fixedly connected inside the eight mounting holes. The exhaust pipes 23 penetrate through the mounting holes and extend downward to be fixedly connected with air jet covers; in this way, the air output of the fan 16 can be adjusted according to the direction of the shoes. When the shoes are conveyed from left to right, the air output of the left fan 16 can be increased, and the air output of the right fan 16 can be reduced. In this way, the drying efficiency of the shoes can be greatly improved.

[0045] In summary, compared with the prior art, the circulating drying device has at least the following beneficial effects: By arranging a circulating mechanism in the housing 1, the gas in the drying chamber 8 can be collected through the recycling mechanism, heating mechanism and the fan 16 therein. The collected gas can be dehumidified and adsorbed through the activated carbon filter 15, making the circulating gas dry and odorless. The filtered gas is heated by the heating mechanism and then transported back to the drying chamber 8 again, enabling the hot air to be recycled, not only avoiding the leakage of hot air, but also improving the drying efficiency. At the same time, under the adjustment of the temperature control mechanism, the electric cylinder 25 drives the movable plate 24 to move up and down, so that the height of the exhaust pipe 23 can be adjusted to dry different shoes, greatly improving the drying efficiency.

[0046] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
