[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 The refined cotton dual-chamber drying device in this embodiment includes a drying box 1, which is an insulated box structure with a sealed door.

[0037] The drying oven 1 is also fixedly installed with a drying chamber 2, and the drying chamber 2 is equipped with a drying cart 3.

[0038] The drying chamber 2 is a rectangular structure with a deep groove on the front, and gaps are reserved between the inner top wall, the rear inner wall, and the two inner side walls of the drying chamber 2 and the drying box 1.

[0039] It should be noted that the gap between drying chamber 2 and drying box 1 is reserved at 4-6cm to facilitate the even distribution of heating air outside drying chamber 2.

[0040] Furthermore, a partition 201 is inserted through the middle of the drying chamber 2 and is attached to the inner top wall of the drying box 1. The partition 201 separates the deep groove opened on the front of the drying chamber 2 to form two independent cavities, which are used to distribute the volume of the drying chamber 2 to form two drying areas.

[0041] It should be noted that a connecting doorway 202 is provided through the middle of the partition 201. The connecting doorway 202 is rectangular in structure to facilitate the transfer of the drying cart 3 between the two drying areas.

[0042] It is worth noting that a crossbeam plate 203 is fixedly connected to the top of the drying chamber 2. The crossbeam plate 203 is flush with the cross section of the drying box 1, so that the crossbeam plate 203 divides the gap between the drying box 1 and the drying chamber 2 into an upper rectangular space and a lower U-shaped space.

[0043] Please see Figures 1 to 2In this embodiment, the top of the drying chamber 1 is also connected to a grid dehumidification pipe 103 and an exhaust pipe 102 for maintaining air pressure balance. The grid dehumidification pipe 103 and the exhaust pipe 102 each include two sets. The two sets of grid dehumidification pipe 103 and exhaust pipe 102 are symmetrically distributed on both sides of the partition 201 to connect the two areas of the drying chamber 2.

[0044] In addition, blowers 101 are installed on both outer walls of the drying chamber 1 to improve the uniformity of the distribution of heated air in the drying chamber 1. The upper and lower areas of the corresponding crossbeam plate 203 are interconnected so that the air blown into the drying chamber 1 by the blowers 101 can be mixed with the heated air.

[0045] In order to facilitate the distribution of heat source in the drying chamber 2, grid holes 204 are provided through the two side walls of the drying chamber 2. The grid holes 204 and the gap outside the drying chamber 2 are interconnected, so that heated air can enter the drying chamber 2 to dry the drying cart 3 inside the drying chamber 2.

[0046] Please see Figure 3 In this embodiment, the drying cart 3 includes a structural frame 301 for support and trays 302 continuously distributed between the structural frames 301. The trays 302 are stacked and spaced apart, and a mobile trolley 303 is fixedly arranged below the structural frame 301.

[0047] It should be noted that the lower end of the mobile trolley 303 is designed to be flat, and the bottom surface of the mobile trolley 303 is in contact with the bottom wall of the drying chamber 2, so as to reduce the gap between the mobile trolley 303 and the drying chamber 2. The mobile trolley 303 is composed of a motor, a drive shaft and rollers for movement. The rollers are hidden in the middle of the mobile trolley 303 and contact the drying chamber 2 downwards, which is used to control the movement of the trolley 303 within the drying chamber 2.

[0048] Understandably, the size of the drying cart 3 is smaller than the size of the connecting doorway 202, which allows the drying cart 3 to move horizontally and change the two spaces inside the drying chamber 2.

[0049] This design allows refined cotton to be evenly stored on the tray 302, and at the same time, driven by the moving trolley 303, it is easy to control the transfer of the drying cart 3 between the two independent spaces of the drying chamber 2.

[0050] Please see Figure 3 In this embodiment, extension frames 4 are also fixedly installed on both sides of the structural frame 301. An insulation board 5 corresponding to the connecting doorway 202 is fixedly connected to the extension frame 4. The size of the insulation board 5 is the same as that of the connecting doorway 202, and the thickness of the insulation board 5 is less than that of the connecting doorway 202.

[0051] This design allows the drying cart 3 to be placed in any area of ​​the drying chamber 2, regardless of where it is located. The insulation board 5 on one side of the drying cart 3 can be embedded in the connecting doorway 202 to seal the partition 201, thus creating two independent spaces within the drying chamber 2.

[0052] Based on this, by controlling the ambient temperature of the two independent spaces in the drying chamber 2 to tend to different temperature ranges, and by moving the drying cart 3 between the two independent spaces, a rapid temperature control effect can be achieved.

[0053] To prevent the drying cart 3 from moving freely, a pneumatic component is provided on the insulation board 5. A groove 501 is provided on the side of the insulation board 5 facing the top of the drying cart 3. The pneumatic component includes a sliding plate 502 and a high-temperature cylinder 503 for pushing the sliding plate 502. The sliding plate 502 slides relative to the groove 501, so that the sliding trajectory of the sliding plate 502 is stable and can be lifted to the outside of the insulation board 5 under the push of the high-temperature cylinder 503 to prevent the insulation board 5 from going over the partition 201.

[0054] Please see Figure 4 In this embodiment, a heat source pipe 6 for providing a heat source is provided on the rear side of the drying box 1, and a heating port 7 is also connected to the rear side of the drying box 1. The heat source pipe 6 and the heating port 7 are interconnected.

[0055] Among them, the heat source pipe 6 is a T-shaped tee pipe. Both ends of the heat source pipe 6 are connected to two heating ports 7 respectively, and the other end is connected to the heating element for inputting heated air.

[0056] Furthermore, a shut-off valve 601 for controlling the on / off of the heat source is provided at one end of the heat source pipe 6 connected to the heating air. A pressure regulating valve 602 is provided at both ends of the heat source pipe 6 and the heating port 7 for controlling the input of the heat source, thereby realizing zoned temperature control.

[0057] It should be noted that a pressure relief pipe 8 is connected to the rear side of the drying oven 1 via a valve to deal with emergency situations.

[0058] The working principle of the above embodiment is as follows: The drying cart 3, loaded with refined cotton, is placed inside the drying chamber 2. The drying box 1 is closed, and a heat source is input into the drying box 1 through the heat source pipe 6. The heat source is distributed within the inner cavity of the drying chamber 2 along the three-way branch of the heat source pipe 6. Then, the blower 101 is controlled to blow air into the drying box 1 to improve the uniformity of heat source distribution within the drying chamber 2. Since the insulation plate 5 on the outside of the drying cart 3 is embedded in the connecting doorway 202 on the partition 201, and simultaneously, the high-temperature cylinder 503 is controlled to push the sliding plate 502 to rise above the insulation plate... Plate 5 blocks the drying cart 3 to one side of partition 201. At this time, the two equally divided spaces in the drying chamber 2 are temperature-isolated from each other. By adjusting the pressure regulating valve 602 on the heat source pipe 6, a temperature difference of 20°C is formed between the two areas in the drying chamber 2. When the refined cotton is being dried in a gradient, the slide plate 502 is retracted by controlling the high temperature cylinder 503, and the drying cart 3 is moved to another space in the drying chamber 2 under the traction of the moving trolley 303. The partition 201 is sealed again by the heat insulation plate 5 to achieve efficient temperature control for drying the refined cotton.

[0059] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.
