[0002] In the field of zinc oxide production, rotary kilns are widely used as core equipment in the calcination treatment of zinc slag and zinc-containing waste. They consist of processes such as gas flow, fuel combustion, heat transfer and material movement. The rotary kiln is designed to ensure that the fuel can burn completely and that the heat from the fuel combustion can be effectively transferred to the material. After receiving the heat, the material undergoes a series of physicochemical changes, and finally forms the finished clinker.

This operation is prone to clogging, which affects the efficiency of the rotary kiln in processing zinc oxide. In addition, adding material all at once will cause a sharp change in the temperature inside the kiln, which is difficult to control precisely. Furthermore, it will put a large load on the equipment, which may lead to equipment failure and affect the continuity and stability of production.

At the same time, during the pushing process, it will also block the feed hopper 8 to prevent it from continuing to discharge material. While pushing the material, the material in the feed hopper 8 can also be discharged intermittently.

[0039] Example 2

[0040] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-2 and Figure 5-10 The unblocking component 7 includes a rotating rod 71 movably installed on the rear side of the feed frame 3 near the right side and a drive gear 72 fixedly sleeved on the outside of the rotating rod 71. A driven gear 73 meshes with the left side of the drive gear 72, and a movable shaft is fixedly installed through the middle of the driven gear 73. The front end of the movable shaft is movably installed on the feed frame 3, and a turntable 74 is fixedly installed at the rear end of the movable shaft. A sliding shaft 75 is fixedly installed near the edge of the rear side of the turntable 74. A sliding frame 76 is movably sleeved on the outside of the sliding shaft 75. A connecting plate is fixedly installed at the middle of the top of the sliding frame 76, and a special-shaped connecting rod 77 is fixedly installed on the rear side of the connecting plate. An unblocking plate 78 is fixedly installed at the end of the special-shaped connecting rod 77 away from the connecting plate. Several unblocking rods 79 are fixedly installed at equal intervals at the bottom of the unblocking plate 78, which can drive the several unblocking rods 79 to move back and forth up and down, which is conducive to the unblocking work and avoids blockage during material feeding.

[0041] Specifically, a movable plate 781 is fixedly installed at the middle of the front side of the unblocking plate 78, and a limiting telescopic rod 782 is fixedly installed at the bottom of the movable plate 781. A flat plate 783 is fixedly installed at the lower end of the limiting telescopic rod 782, and the rear side of the flat plate 783 is fixedly installed on the feed frame 3, which serves to guide and limit the movement of the unblocking plate 78, thus ensuring high stability.

[0042] In this embodiment, the transmission assembly 6 includes an L-shaped rack plate 61 located on the rear side of the feed frame 3 near the left side and a transmission gear 62 meshing with the top of the L-shaped rack plate 61 near the right side. The front end of the L-shaped rack plate 61 is fixedly mounted on the movable block 57 on the rear side. A transmission rod 63 is fixedly installed through the middle of the transmission gear 62. An L-shaped support plate is movably mounted on the rear end of the transmission rod 63. The front side of the L-shaped support plate is fixedly mounted on the feed frame 3. A ratchet disc A64 is fixedly mounted on the front end of the transmission rod 63. A ratchet disc B65 is engaged on the front side of the ratchet disc A64. A disc 66 is provided on the front side of the ratchet disc B65. The middle of the front side of the disc 66 is fixedly connected to the rear end of the rotating rod 71. The arrangement of the L-shaped rack plate 61 and the transmission gear 62 facilitates the power to rotate the disc 66 and allows for unidirectional transmission, avoiding interference with the unblocking operation.

[0043] Specifically, the upper and lower sides of the ratchet disc B65 and the disc 66 are elastically connected by a telescopic spring 661, which facilitates the rotation and restoration of the ratchet disc B65.

[0044] In this embodiment: when the movable block 57 moves to the right, it drives the L-shaped rack plate 61 to move to the right. The L-shaped rack plate 61 moving to the right drives the transmission gear 62 to rotate. The transmission gear 62 rotating drives the transmission rod 63 to rotate. The transmission rod 63 rotating drives the ratchet disc A64 to rotate. The ratchet disc A64 rotates in conjunction with the ratchet disc B65, continuously compressing the extension spring 661. When the movable block 57 moves to the left, it drives the ratchet disc A64 to rotate in the opposite direction, engaging with the ratchet disc B65 and causing it to rotate. The rotation of the ratchet disc B65 drives the disc 661. When the disc 66 rotates, it drives the rotating rod 71 to rotate, which in turn drives the driving gear 72 to rotate. The driving gear 72, in turn, drives the turntable 74 to rotate via the driven gear 73. The turntable 74, in turn, drives the sliding frame 76 to move up and down via the sliding shaft 75. The sliding frame 76, in turn, drives the irregular connecting rod 77, in turn, drives the unblocking plate 78, in turn, drives the unblocking rod 79, in turn, thus clearing the material in the feed hopper 8 and preventing blockages.

[0045] Working principle: During use, the material to be processed can be added into the feed hopper 8, and the material in the feed hopper 8 will fall into the feed frame 3. After the material is added into the feed hopper 8, the drive motor 52 can be started. When the drive motor 52 runs, it will drive the reciprocating screw 53 to rotate through the transmission shaft. When the reciprocating screw 53 rotates, it will drive the screw nut 55 to move back and forth left and right. When the screw nut 55 moves left and right, it will drive the adjacent movable block 57 to move left and right synchronously through the L-shaped rod 56. When the movable block 57 moves left and right, it will drive the adjacent moving rod 57 to move left and right synchronously. 71 together drive the push plate 58 to move left and right. When the push plate 58 moves left and right, it will drive the L-shaped baffle plate 59 to move back and forth left and right through the connecting rod 581. When the L-shaped baffle plate 59 moves to the right, it will push the material into the feeding frame 2, so that it can be pushed into the rotary kiln body 1. At the same time, during the pushing process, it will also block the feed hopper 8 to prevent it from continuing to feed. While pushing, it can also allow the material in the feed hopper 8 to be discharged intermittently. In addition, when the movable block 57 moves to the right, it will drive the L-shaped rack plate 61 to move to the right, and the L-shaped rack plate 61 will move to the right. When plate 61 moves to the right, it drives transmission gear 62 to rotate. Transmission gear 62 rotates, which in turn drives transmission rod 63 to rotate. Transmission rod 63 rotates, which in turn drives ratchet disc A64 to rotate. Ratchet disc A64 rotates against ratchet disc B65, continuously compressing the telescopic spring 661. When movable block 57 moves to the left, it drives ratchet disc A64 to rotate in the opposite direction, engaging with ratchet disc B65 and causing it to rotate. The rotation of ratchet disc B65 drives disc 66 to rotate, which in turn drives rotating rod 71 to rotate. When the rotating rod 71 rotates, it drives the driving gear 72 to rotate. When the driving gear 72 rotates, it drives the turntable 74 to rotate through the driven gear 73. When the turntable 74 rotates, it drives the sliding frame 76 to move up and down back and forth through the sliding shaft 75. When the sliding frame 76 moves up and down, it drives the irregular connecting rod 77 to move up and down through the connecting plate. When the irregular connecting rod 77 moves up and down, it drives the unblocking plate 78 to move up and down back and forth. When the unblocking plate 78 moves up and down, it drives the unblocking rod 79 to move up and down back and forth, thereby clearing the material in the feed hopper 8 and preventing blockage.
