[0036] A silicone pad is provided in the limiting groove 1201 of each supporting rod 12 to protect the edge of the filter body 001 and prevent the edge of the filter body 001 from being crushed.

[0037] The working steps of the above embodiment are:

[0038] First, the staff opens the box door 2, takes out each movable frame 7, and adjusts the distance between adjacent sliders 9 according to the size of the filter body 001 to be dried, so as to adapt to the filter bodies 001 of different sizes, and limits the filter bodies 001 of different sizes. Then, a filter body 001 model of the size is taken and placed in two opposite limiting grooves 1201. The two opposite limiting grooves 1201 are in an inverted eight-shaped shape to ensure that the filter body 001 model will not fall off the supporting rod 12. Then, the screw 10 is tightened downward so that the screw 10 is fixed. 10 contacts the slide rail 8 to fix the slider 9, and at the same time, the screw 10 is tightened downward, and the spring on the screw 10 is also cooperated to fix the connecting piece 11, and then the filter body 001 model is taken away, and then the external manipulator is controlled to place the filter body 001 on the two opposite limit grooves 1201 in turn. After the staff has checked that the placed filter body 001 is correct, the movable frame 7 is put back on the corresponding carrier plate 6, and the movable frame 7 is pushed into the oven 1, and then the movable frame 7 with the filter body 001 is put back into the oven 1 in turn, and the oven door 2 is closed and locked.

[0039] All fans 4 are controlled to start, and the outside air is sucked into the lower air chamber 1001 by the fans 4. When the outside air passes through the dustproof net, the dustproof net intercepts the dust impurities in the air. When there are a lot of dust impurities intercepted on the dustproof net, in order to avoid affecting the air intake effect of the oven 1, the dustproof net can be removed and cleaned. The air filtered by the dustproof net enters the lower air chamber 1001, and then the air enters the oven 1 through the air port 1002. At the same time, the heater 5 is controlled to start, and the corresponding heating temperature of the heater 5 is set according to the different materials of the filter body 001. The air passing through the air port 1002 is heated by the heater 5 and flows upward, and the rising hot air The filter body 001 is dried by air. Since the position of the limiting groove 1201 and the position of the air outlet 1002 are staggered, water drops from the filter body 001 will not directly drip on the heater 5 to affect the normal operation of the heater 5. During the drying process of the filter body 001, the contact position between the filter body 001 and the supporting rod 12 is not in direct contact with the hot air, resulting in insufficient drying of the filter body 001. Therefore, by providing the air-expanding telescopic member 101, when the filter body 001 is dried, the temperature in the oven 1 rises, and the temperature rise causes the nitrogen in the air-expanding telescopic member 101 to expand greatly due to the heat. Figure 5 As shown, the piston rod of the inflatable telescopic member 101 extends downward, synchronously driving the connecting rod Ⅰ102 and the corresponding parts thereon to move downward, so that the pin rod 104 moves downward. As the wedge-shaped portion of the pin rod 104 moves downward, the two adjacent supporting rods 12 start to rotate under the contraction cooperation of the corresponding tension springs 105, as shown in FIG. Figure 7As shown, the contact point between the filter body 001 and the limiting groove 1201 begins to move from the horizontal position A to the horizontal position B, as shown in FIG. Figure 8 As shown, as the temperature rises, the contact position between the supporting rod 12 and the filter body 001 changes, thereby avoiding the problem that the contact position between the filter body 001 and the supporting rod 12 remains unchanged, resulting in the filter body 001 being unable to be fully dried, affecting the quality of the filter body 001, wherein the diameter of the filter body 001 is larger than the distance between the rotating axes of the two supporting rods 12 on the opposite sides of the limiting groove 1201, so that the filter body 001 will not fall off the supporting rod 12 no matter how the supporting rod 12 rotates.

[0040] The hot air in the oven 1 first flows upward, the air pressure in the upper part of the oven 1 increases, and the hot air is finally discharged from the exhaust pipe 3. After the preset drying time is reached, the heater 5 is controlled to be turned off, and the fan 4 still draws air from the outside and blows it into the oven 1. The inside of the oven 1 is cooled down through the air flow, and then the fan 4 is controlled to be turned off. The staff opens the door 2 and controls the external manipulator to take out the movable racks 7 in the oven 1 one by one. During the drying process of the filter body 001 in the oven 1, other movable racks 7 can also be taken out from the external tool rack, and the filter body 001 can be placed on the corresponding limit groove 1201. Therefore, after the filter body 001 in the oven 1 is dried, the movable rack 7 in the oven 1 is taken out, and the movable rack 7 on which the filter body 001 has been placed can be put into the oven 1, thereby effectively improving the processing efficiency of the filter body 001.

[0041] Second embodiment

[0042] On the basis of the first embodiment, according to Figure 3 and Figure 4 As shown, an upper air chamber 1003 is opened on the top of the oven 1; a plurality of exhaust ports are opened at the lower part of the upper air chamber 1003; an air flow cavity 1004 is opened inside each of the left and right side panels of the oven 1; the upper air chamber 1003 is connected with the two air flow cavities 1004 through connecting pipes; a reflux cavity 6001 is opened in each of the supporting plates 6; each air flow cavity 1004 is connected with the corresponding reflux cavity 6001.

[0043] Each reflux cavity 6001 is provided with absorbent cotton on the opposite sides thereof for absorbing moisture in the hot air.

[0044] The working steps of the above embodiment are:

[0045] On the basis of the above embodiment, it should be noted that when the air flows upward after being heated, the drying effect of the filter body 001 located near the middle of the support rod 12 is better than the drying effect of the filter body 001 near the two ends of the support rod 12. Therefore, a plurality of exhaust ports are provided in the upper air chamber 1003 so that the rising hot air first enters the upper air chamber 1003, and then the hot air enters the two air flow chambers 1004 on the side wall of the oven 1, and then the hot air re-enters the oven 1 through the reflux chamber 6001. And since each movable frame 7 is arranged on the supporting plate 6, when the hot air ejected from the reflux chamber 6001 rises, it will directly heat the filter body 001 near the edge of the supporting rod 12, thereby achieving that the filter body 001 at each location of the supporting rod 12 can be fully dried, and during the above operation process, the hot air on the upper part of the oven 1 is guided to heat the filter body 001 near the edge of the supporting rod 12, thereby achieving the recovery of waste heat and effectively increasing the utilization rate of thermal energy.
