[0001] The utility model belongs to the technical field of drying rotary kilns, and particularly relates to a drying rotary kiln. Background Art
[0002] The rotary drying kiln is a commonly used drying device, usually an inclined cylindrical barrel made of metal materials such as steel plates. The length and diameter of the barrel are designed according to the production scale and the material handling capacity. The inclination angle is generally about 3-5 degrees, which enables the material to slowly move from the feeding end to the discharging end under the combined action of gravity and rotational force inside the barrel. The tail smoke chamber of the kiln is located at the tail of the rotary drying kiln, which is a transition part connecting the kiln body and the flue. It is usually designed as a relatively large cavity structure, and its shape is generally rectangular or polygonal to adapt to the connection with the kiln body outlet and the flue inlet. Due to the long-term sedimentation of soot in the tail smoke chamber on the lining plate of the tail kiln, it needs to be cleaned regularly. Since the tail kiln is sealed and installed on the barrel, due to its large volume, it is difficult to remove it from the barrel when cleaning the soot, which is not conducive to the staff to clean the soot deposited on the lining plate. Content of the Utility Model
[0003] The utility model provides a drying rotary kiln, which has the characteristic that it is not convenient for the staff to clean the soot deposited on the lining plate.
[0004] The utility model provides the following technical solution: It includes a kiln barrel body and a kiln tail. One end of the kiln tail is rotatably connected with a rotating plate, and a docking hole communicating with the kiln barrel body is opened on the rotating plate. A plurality of mounting plates matching with the docking hole are slidably connected to the inner wall of the kiln barrel body. A rotating groove is opened at the center of the rotating plate, and a central plate is rotatably connected to the inner wall of the rotating groove. A sliding rod is slidably connected to the inner wall of the central plate. A lead screw is rotatably connected to the center of the sliding rod. A connecting ring is threadedly connected to the outer wall of the lead screw. A horizontal rod penetrating through the connecting ring is installed on one side of the sliding rod. An adjusting ring is arranged at one end of the sliding rod, and a side plate is fixedly connected to the outer wall of the adjusting ring. A connecting plate is fixedly connected to the inner wall of the mounting plate, and a docking plate corresponding to the side plate is fixedly connected to one end of the connecting plate.
[0005] Wherein, a limiting hole is opened on the docking plate, and a plug rod is fixedly connected to one side of the side plate, and the plug rod is matched with the limiting hole.
[0006] Wherein, a sealing plate is installed on the inner wall of the docking hole, a connecting groove is opened on the inner wall of the docking hole, a convex plate matching with the connecting groove is installed on the sealing plate, and the convex plate and the convex plate are connected by a pin.
[0007] Among them, a fixed rod is installed on the inner wall of the kiln tail, and one side of the fixed rod is rotatably connected to one end of the lead screw.
[0008] Among them, the sliding rod and the adjusting ring are connected by a connecting rod. A rotating groove is formed at the center of the rotating plate, and the central plate matches the rotating groove.
[0009] Among them, a plurality of docking blocks corresponding to the mounting plates are fixedly connected to the outer wall of the rotating plate. A rack is detachably connected to the docking blocks. A motor is fixedly connected to the rack, and the driving end of the motor is engaged with the lead screw.
[0010] Among them, both ends of the rack correspond to two of the relatively symmetric docking blocks, and the rack is slidably connected to the rotating plate.
[0011] The beneficial effect of the present utility model is that the docking holes formed in the rotating plate can correspond to each section of the mounting plate, and then the sliding rod, the adjusting ring and the side plate can correspond to different docking plates. The connecting ring rotatably connected to the inner wall of the adjusting ring is threadedly connected to the lead screw. After the connecting ring is limited by the horizontal rod, the side plate can adjust the positions of the respective docking plates, so that the staff can conveniently clean the soot adhering to the mounting plate, avoiding directly separating the kiln tail from the kiln barrel body. Since its volume is large, it is not conducive to the staff to clean the soot residue in the kiln tail.

[0019] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: including a kiln barrel body 1 and a kiln tail 11, one end of the kiln tail 11 is rotatably connected to a rotating plate 2, a docking hole 21 communicating with the kiln barrel body 1 is opened on the rotating plate 2, a plurality of mounting plates 12 matching the docking hole 21 are slidably connected to the inner wall of the kiln barrel body 1, a rotating groove 231 is opened at the center of the rotating plate 2, a central plate 23 is rotatably connected to the inner wall of the rotating groove 231, a slide bar 24 is slidably connected to the inner wall of the central plate 23, a lead screw 31 is rotatably connected to the center of the slide bar 24, a connecting ring 252 is threadedly connected to the outer wall of the lead screw 31, a horizontal rod 253 passing through the connecting ring 252 is installed on one side of the slide bar 24, an adjusting ring 25 is provided at one end of the slide bar 24, a side plate 26 is fixedly connected to the outer wall of the adjusting ring 25, a connecting plate 13 is fixedly connected to the inner wall of the mounting plate 12, and a docking plate 14 corresponding to the side plate 26 is fixedly connected to one end of the connecting plate 13.
[0020] In this implementation: During use, the kiln tail 11 is hermetically installed at one end of the kiln barrel body 1. The rotating plate 2 rotatably connected to one end of the kiln tail 11 can adjust the position of the docking hole 21 opened on the rotating plate 2 through rotation to correspond to the corresponding position of the kiln tail 11, so that the docking hole 21 can correspond to the mounting plate 12 slidably connected to the inner wall of the kiln tail 11. After the docking hole 21 corresponds to the mounting plate 12, the staff can slide the mounting plate 12 to slide outward from the inner wall of the kiln tail 11 and pass through the docking hole 21 opened on the rotating plate 2, so that the mounting plate 12 can be separated from the kiln tail 11. After separating a certain mounting plate 12, it can be sequentially separated through the corresponding docking hole 21 at this time, avoiding the need to integrally separate the kiln tail 11 from the kiln barrel body 1 and then separate the mounting plate 12. When separating the mounting plate 12, the central plate 23 rotatably connected to the center of the rotating plate 2 can ensure that when the rotating plate 2 rotates, the central plate 23 will not affect the rotation of the rotating plate 2 when being limited. The sliding rod 24 slides at the center of the central plate 23. The adjusting ring 25 provided at one end of the sliding rod 24 can perform synchronous position adjustment with the adjusting ring 25, enabling the staff to rotate the sliding rod 24 outside the rotating plate 2. After the sliding rod 24 rotates, the side plate 26 fixedly connected to the outer wall of the adjusting ring 25 can rotate to the corresponding position of the docking plate 14 installed on the inner wall of the mounting plate 12. The docking plate 14 is supported and fixed by the connecting plate 13, enabling the equidistantly distributed mounting plates 12 to be erected by the connecting plate 13, so that when the side plate 26 rotates and adjusts the position, the side plate 26 can correspond to each docking plate 14. After corresponding, at this time, the connecting ring 252 can be threadedly connected to the lead screw 31 rotatably connected to the center of the central plate 23. After the lead screw 31 rotates under external drive, due to its threaded connection with the connecting ring 252, the connecting ring 252 can adjust its position on the outer wall of the lead screw 31 under the limitation of the horizontal rod 253, so that the side plate 26 can perform synchronous position adjustment with the adjusting ring 25, enabling the side plate 26 to push the corresponding docking plate 14 and displace the docking plate 14. At this time, the docking hole 21 corresponds to the mounting plate 12 connected to the docking plate 14, enabling the mounting plate 12 to be pushed, so that the mounting plate 12 can slide out of the docking hole 21, facilitating the staff to clean the soot attached to the mounting plate 12 and avoiding directly separating the kiln tail 11 from the kiln barrel body 1, which is not conducive to the staff to clean the soot residue in the kiln tail 11 due to its large volume.
[0021] The docking plate 14 is provided with a limiting hole 15. One side of the side plate 26 is fixedly connected with a plug rod 27, and the plug rod 27 is matched with the limiting hole 15. The limiting hole 15 opened on the docking plate 14 is used to correspond to the plug rod 27 fixedly connected to one side of the side plate 26, so that the plug rod 27 can be inserted into the limiting hole 15 to ensure that the side plate 26 is limited on the docking plate 14, enabling the side plate 26 to be firmly connected to the docking plate 14 during displacement and pushing the docking plate 14 to displace.
[0022] A sealing plate 22 is installed on the inner wall of the docking hole 21. A connecting groove 211 is opened on the inner wall of the docking hole 21. A convex plate 221 matched with the connecting groove 211 is installed on the sealing plate 22, and the convex plates 221 are connected by a pin 222.
[0023] A fixed rod 32 is installed on the inner wall of the kiln tail 11. One side of the fixed rod 32 is rotatably connected to one end of the lead screw 31. The fixed rod 32 installed on the inner wall of the kiln tail 11 is used to support one end of the lead screw 31, so that the lead screw 31 is stably supported at the center in the kiln tail 11, enabling it to adjust the horizontal position of the connecting ring 252.
[0024] The sliding rod 24 is connected to the adjusting ring 25 through a connecting rod 251. A rotating groove 231 is opened at the center of the rotating plate 2, and the central plate 23 is matched with the rotating groove 231.
[0025] A plurality of docking blocks 34 corresponding to the mounting plate 12 are fixedly connected to the outer wall of the rotating plate 2. A frame rod 33 is detachably connected to the docking block 34. A motor 3 is fixedly connected to the frame rod 33, and the driving end of the motor 3 is engaged with the lead screw 31. The docking blocks 34 fixedly connected to the outer wall of the rotating plate 2 are used to erect the frame rod 33, enabling the frame rod 33 to support the motor 3. Thus, after the driving end of the motor 3 is engaged with the lead screw 31, it can drive the lead screw 31 to rotate, and through the connection and support of both ends of the frame rod 33 with two of the docking blocks 34, it can make way for the docking hole 21, enabling the mounting plate 12 to slide out through the docking hole 21.
[0026] Both ends of the frame rod 33 correspond to two of the symmetric docking blocks 34, and the frame rod 33 is slidably connected to the rotating plate 2. The correspondence between both ends of the frame rod 33 and the docking blocks 34 enables every two docking blocks 34 as a group to support the frame rod 33, and the sliding connection between the frame rod 33 and the rotating plate 2 ensures that the rotation of the rotating plate 2 is not limited by the frame rod 33.
[0027] Working principle and usage process of the utility model: The docking holes 21 opened on the rotating plate 2 rotatably connected to one end of the kiln tail 11 correspond to the mounting plate 12. After the docking holes 21 and the mounting plate 12 are corresponding, at this time, the sliding rod 24 can slide at the center of the center plate 23. After the sliding rod 24 rotates, the side plate 26 fixedly connected to the outer wall of the adjusting ring 25 can rotate to the corresponding position of the docking plate 14 installed on the inner wall of the mounting plate 12. After corresponding, at this time, it can be threadedly connected with the lead screw 31 rotatably connected to the center of the center plate 23 through the connecting ring 252. After the lead screw 31 is rotated by an external drive, since the connecting ring 252 is threadedly connected with it, under the limit of the horizontal rod 253, the position of the connecting ring 252 on the outer wall of the lead screw 31 can be adjusted, so that the side plate 26 can be synchronously adjusted in position with the adjusting ring 25, and the side plate 26 can push the corresponding docking plate 14, so that the docking plate 14 is pushed to displace. At this time, the mounting plate 12 connected to the docking plate 14 corresponds to the docking hole 21, so that the mounting plate 12 can be pushed, so that the mounting plate 12 can slide out of the docking hole 21, so that the staff can conveniently clean the soot attached to the mounting plate 12, avoiding directly separating the kiln tail 11 from the kiln barrel body 1. Because of its large volume, it is not conducive to the staff to clean the soot residue in the kiln tail 11.
