DETAILED DESCRIPTION
[0021] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0022] like Figure 1 As shown, a rotary drying line includes a drying room 1 (in order to show the internal structure, the drying room 1 is shown as a frame only), a rotary assembly and a driving device 2, and the rotary assembly includes a conveying mechanism 3. Figures 2 to 6 As shown, the conveying mechanism 3 includes a mounting beam 4, a driving sprocket 5, a driven sprocket 6, a conveyor chain 7 (only a portion of the conveyor chain 7 is shown schematically), and several suspension mechanisms. The driving sprocket 5 and the driven sprocket 6 are both rotatably connected to the mounting beam 4, and the driving sprocket 5 and the driven sprocket 6 are connected by a transmission through the conveyor chain 7. The suspension mechanism includes a support rod 8 and a suspension member. One end of the support rod 8 is fixedly connected to the outside of the conveyor chain 7, and the suspension member is rotatably connected to the other end of the support rod 8. The mounting beam 4 is fixedly mounted at the upper portion of the drying room 1. The upper and lower sides of the conveyor chain 7 are parallel to the horizontal direction and located in the same vertical plane. The rotation axis of the suspension member rotating on the support rod 8 is perpendicular to the vertical plane of the conveyor chain 7.
[0023] During the drying operation, the materials to be dried are hung on the respective hanging parts. Starting the driving device can drive the active sprocket 5 to rotate, thereby driving the conveyor chain 7 and the various hanging mechanisms to reciprocate in the vertical plane. The support rods 8 on the upper and lower sides of the conveyor chain 7 are both vertically arranged, so that there is a gap between the upper and lower hanging parts of the conveyor chain 7 to accommodate the materials. At the same time, due to the rotatable connection between the hanging parts and the support rods 8, during the reciprocating rotation process after the materials are hung, the materials can always maintain their hanging posture under the action of their own weight (such as Figure 7 The rotary drying line can keep the materials in a suspended position in the drying room and continuously rotate back and forth, which can make the drying of each material more uniform and improve the overall drying efficiency.
[0024] When implementing it specifically, Figure 3 、 Figure 4 As shown, the conveying mechanism 3 also includes a guide device, which includes two guide rods 9. The two guide rods 9 are arranged below the mounting beam 4 and are parallel to each other. A first guide groove is formed between the two guide rods 9, and each strut 8 can slide in the first guide groove. A second guide groove is provided on the top surface of the mounting beam 4, and a third guide groove is formed between the guide rods 9 and the bottom surface of the mounting beam 4. The upper side of the conveyor chain 7 is slidably arranged in the second guide groove, and the lower side of the conveyor chain 7 is slidably arranged in the third guide groove. The second guide groove and the third guide groove are used to limit the operation of the conveyor chain 7. The guide device also includes two guide rings 10. The shape of the guide rings 10 is adapted to the shape of the conveyor chain 7 and the length of the strut 8. The two guide rings 10 are parallel to each other. A fourth guide groove is formed between the two guide rings 10. Several struts 8 can be slidably arranged in the fourth guide groove. The first guide groove and the fourth guide groove are used to limit the position of each strut 8 during the aforementioned reciprocating rotation process.
[0025] The aforementioned rotary assembly can be provided separately, for example, with its mounting beam 4 fixedly positioned in the middle of the drying chamber 1. Each suspension mechanism includes two suspension members, symmetrically positioned on either side of the support rod 8. During use, materials are suspended from the two suspension members for drying. This embodiment employs a cantilevered suspension system for a single material, which has some limitations on the size and weight of the material and is therefore primarily suitable for drying smaller materials.
[0026] In this embodiment, Figure 1 As shown, the rotary assembly includes two conveying mechanisms 3, the two conveying mechanisms 3 are symmetrically arranged, the two conveying chains 7 are parallel to each other, and each suspension member is arranged on the opposite side of the two conveying mechanisms, and a suspension slot is opened on the suspension member. Figure 7 As shown, when in use, the two ends of the material are respectively placed in the hanging notches of two opposite hanging parts, which can achieve continuous drying of materials with larger size and weight.
[0027] When implementing it specifically, Figure 6 As shown, the aforementioned hanging member can be fabricated from a square plate 11 and an angle steel block 12. One side of the square plate 11 is rotatably connected to the support rod 8, while one end of the angle steel block 12 is fixedly connected to the other side of the square plate 11 by welding or other means. The hanging member is thus fabricated. The aforementioned hanging notch is formed between the inner side of the angle steel block 12 and the square plate 8. This hanging notch is square in shape. When the material is suspended via the square rod, the rotational freedom among the material, the square rod, and the hanging member is constrained, facilitating the maintenance of the material's posture while suspended.
[0028] Further, combined Figure 5 、 Figure 7 As shown, the driving device 2 includes a driving shaft 13 and two transmission mechanisms, and the transmission mechanism includes a first sprocket, a second sprocket 14 and a driving chain 15. The first sprocket and the second sprocket 14 are connected by the driving chain 15; the driving shaft 13 is rotatably arranged outside the drying room 1, and the two first sprockets are fixedly mounted on both ends of the driving shaft 13, and the two second sprockets 14 are coaxially fixedly connected to the two driving sprockets 5. When the driving shaft 13 rotates, it can drive the two first sprockets to rotate, and the two second sprockets 14 can be synchronously driven to rotate through the transmission mechanism, and then the two driving sprockets 5 rotate synchronously, thereby realizing the synchronous drive of the two conveying mechanisms 3; the driving shaft 13 and the driving motor that drives it to rotate are arranged outside the drying room 1 to avoid being affected by hot air. It should be noted that Figure 5 The figure is only a schematic diagram of the structure. The position shown on the upper side of the chain 7 in the figure is misplaced. It should be understood that the upper side of the conveyor chain 7 here should be slidably set in the second guide groove. The specific implementation of this part shall be subject to the written record.
[0029] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
