Referring to fig. 1, in some embodiments of the present invention, a first air outlet 12 is provided on a cabinet 10 above a heater 30. At this time, after the dehumidifier dries and heats the air, the hot air is discharged into the box 10 from the first air inlet 11 at the upper part of the rear end of the box 10, the hot air is filled at the upper part inside the box 10, and after reaching the second air inlet 22 above the top of the oven 20, the hot air enters the oven 20 from the second air inlet 22 and passes through the conveying component inside the oven 20, and the film material is placed on the conveying component, so that part of moisture can be taken away on the film material by the dried hot air, and meanwhile, the film material is heated to evaporate the moisture in the film material, thereby carrying out preliminary drying and dehumidification on the film material.
After passing through the membrane material, the hot air is discharged from a second air outlet 23 on the right side of the lower end of the oven 20; the hot air discharged from the second air outlet 23 further enters the lower part of the side air duct 13, and the heater 30 positioned in the middle of the side air duct 13 can perform secondary heating on the moist hot air; after the heater 30 is utilized to heat the hot air, the hot air is discharged to the upper part of the heater 30, namely the upper part of the side air duct 13, returns to the upper part inside the box 10, and can pass through the second air inlet 22 along with fresh hot air conveyed from the dehumidifier, enter the oven 20, and dry and dehumidify the film materials on the conveying assembly, so that the aim of drying and dehumidifying the film materials is fulfilled, the drying and dehumidifying efficiency can be improved, and the energy consumption can be reduced. In addition, a part of the hot air heated by the heater 30 is returned to the dehumidifier through the first air outlet 12 to be circulated next time.
Referring to fig. 1, in other embodiments of the present invention, a first air outlet 12 is provided on a cabinet 10 below a heater 30. At this time, after the dehumidifier dries and heats the air, the hot air is discharged into the box 10 from the first air inlet 11 at the upper part of the rear end of the box 10, the hot air is filled at the upper part inside the box 10, and after reaching the second air inlet 22 above the top of the oven 20, the hot air enters the oven 20 from the second air inlet 22 and passes through the conveying component inside the oven 20, and the film material is placed on the conveying component, so that part of moisture can be taken away on the film material by the dried hot air, and meanwhile, the film material is heated to evaporate the moisture in the film material, thereby carrying out preliminary drying and dehumidification on the film material.
After passing through the membrane material, the hot air is discharged from a second air outlet 23 on the right side of the lower end of the oven 20; the hot air discharged from the second air outlet 23 further enters the lower part of the side air duct 13, and the heater 30 positioned in the middle of the side air duct 13 can perform secondary heating on the moist hot air; after the heater 30 is utilized to heat the hot air, the hot air is discharged to the upper part of the heater 30, namely the upper part of the side air duct 13, returns to the upper part inside the box 10, and can pass through the second air inlet 22 along with fresh hot air conveyed from the dehumidifier, enter the oven 20, and dry and dehumidify the film materials on the conveying assembly, so that the aim of drying and dehumidifying the film materials is fulfilled, the drying and dehumidifying efficiency can be improved, and the energy consumption can be reduced. In addition, part of the hot air conveyed from the second air outlet 23 can be conveyed out of the box 10 from the first air outlet 12 and returned to the dehumidifier for the next cycle.
It should also be noted that in other embodiments, the first air outlet 12 may be disposed on the case 10 and located above and below the heater 30. It will be appreciated that after the dried hot air passes through the membrane material, the hot air is discharged from the second air outlet 23 on the right side of the lower end of the oven 20; the heater 30 located in the middle of the side air duct 13 can perform secondary heating on the hot air and discharge the hot air to the upper side of the heater 30, the secondary heated hot air can pass through the second air inlet 22 along with fresh hot air conveyed from the dehumidifier, and enter the oven 20 to dry and dehumidify the film on the conveying assembly, so that the aim of drying and dehumidifying the film is fulfilled, the drying and dehumidifying efficiency can be improved by circulating the process, and the energy consumption can be reduced. In addition, part of the hot air conveyed from the second air outlet 23 can be conveyed back to the dehumidifier from the first air outlet 12 above after being heated by the heater 30, so that the dehumidifier is convenient to heat and dehumidify; the first air outlet 12 below the heater 30 can be directly conveyed out of the box 10 and returned to the dehumidifier for drying and dehumidification, and the next cycle is waited for.
In view of the above three embodiments, it can be understood that the different positions of the first air outlet 12 enable the distribution of the flow field of the hot air in the side air duct 13 and the oven 20 to meet the requirement of the flow line production. Numerical calculation and simulation of the hot air flow field show that under three different arrangement conditions of the first air outlet 12, hot air gas conveyed from the first air inlet 11 is uniformly distributed in the front-rear direction and the left-right direction of the upper belt 211; meanwhile, the gas conveyed in the oven 20 by the internal circulation fan 40 is distributed in all areas of the upper belt 211 approximately identically, so that the requirement of the flow line production can be met. In addition, it will be appreciated that the first air outlet 12 is located below the heater 30 to facilitate the evacuation of the gases within the oven 20, while having the potential to save energy, relative to the situation where the first air outlet 12 is located above the heater 30. Because the temperature of the gas needs to be reduced to condense the moisture, and the temperature of the gas below the heater 30 is lower than that of the gas above the heater 30, the gas is conveniently discharged, and the first air outlet 12 is positioned at one side of the second air outlet at the same time, so that the gas is conveniently discharged.
