[0001] This utility model relates to the technical field of feeding mechanisms, specifically to a feeding mechanism for a rotary kiln combustion chamber. Background Technology

[0002] The feeding mechanism of the rotary kiln combustion chamber is a very important component. The ease of maintenance of the feeding mechanism determines the utilization rate of the rotary kiln equipment. The feeding mechanism can continuously provide a large amount of combustion raw materials to the rotary kiln combustion chamber, enabling the rotary kiln combustion chamber to continuously provide a heat source for calcination operations.

[0003] Currently, the feeding mechanism pours a large amount of fuel into the storage hopper, which continuously supplies fuel to the combustion chamber. However, the accumulation of a large amount of fuel in the storage hopper can cause problems with fuel delivery. Sometimes, manual unblocking is required at the top of the storage hopper. There is an urgent need to design a feeding mechanism for the rotary kiln combustion chamber to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for the combustion chamber of a rotary kiln to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding mechanism for a rotary kiln combustion chamber includes a storage cylinder with a tapered bottom. A conveying chamber is located at the bottom of the storage cylinder. A conveying pipe connected to the conveying chamber is installed on one side of the bottom of the storage cylinder. A motor is installed at one end of the conveying pipe, and a rotating rod is fixedly connected to the output end of the motor. A auger blade is arranged around the circumference of the rotating rod, and the auger blade is located within the conveying chamber and the conveying pipe. A discharge port is opened at the bottom of one end of the conveying pipe. A vertical lift is installed on one side of the storage cylinder, and a lifting plate is slidably fitted on one side of the vertical lift. A material-carrying frame is rotatably fitted on the top of the lifting plate. A fixed plate is installed on the top of the storage cylinder. A sliding rod is slidably fitted inside the storage cylinder. A movable ring is installed at the top of the sliding rod, and multiple shovel blocks are rotatably fitted at the bottom of the movable ring. A reciprocating lifting mechanism is provided between one end of the sliding rod and one end of the rotating rod.

[0007] Furthermore, a driver is installed on one side of the vertical lift, and a chain is installed on the driver. One end of the chain passes through the vertical lift and is fixedly connected to the top of the lifting plate. Multiple fall arrestors are installed inside the vertical lift.

[0008] Furthermore, a fixing rod is installed on one side of the material loading frame, and a stop bar is installed on one side of the vertical lifting machine, with the stop bar corresponding to the fixing rod.

[0009] Furthermore, multiple support rods are installed between the bottom of the fixing plate and the periphery of the storage cylinder, a ladder is provided on one side of the fixing plate, and a protective frame is installed on one side of the ladder.

[0010] Furthermore, the reciprocating lifting mechanism includes a rotating disk mounted on one end of the rotating rod, a connecting rod rotatably engaged with one side of the rotating disk, a cavity provided inside the storage cylinder, the rotating disk and the connecting rod located inside the cavity, and one end of the connecting rod rotatably engaged with the bottom end of the sliding rod.

[0011] Furthermore, the bottom of the movable ring is provided with multiple connecting blocks, which are arranged in a circular array. The multiple shovel blocks are rotatably engaged with the multiple connecting blocks. The shovel blocks are L-shaped and have an angled bottom.

[0012] In the above technical solution, the feeding mechanism for the rotary kiln combustion chamber provided by this utility model has the following beneficial effects:

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a feeding mechanism for the combustion chamber of a rotary kiln.

[0022] The system includes a storage cylinder 1, the bottom of which is conical and gradually tapers. A conveying chamber 2 is provided at the bottom of the storage cylinder 1. A conveying pipe 3 connected to the conveying chamber 2 is installed on one side of the bottom of the storage cylinder 1. A motor 4 is installed at one end of the conveying pipe 3. A rotating rod 5 is fixedly connected to the output end of the motor 4. A auger blade 6 is provided around the rotating rod 5. The auger blade 6 is located inside the conveying chamber 2 and the conveying pipe 3. A discharge port is opened at the bottom of one end of the conveying pipe 3. A vertical lifting machine 7 is installed on one side of the storage cylinder 1. A lifting plate 8 is slidably fitted on one side of the vertical lifting machine 7. A material carrying frame 9 is rotatably fitted on the top of the lifting plate 8. A fixed plate 10 is installed on the top of the storage cylinder 1. A sliding rod 11 is slidably fitted inside the storage cylinder 1. A movable ring 12 is installed at the top of the sliding rod 11. Multiple shovel blocks 13 are rotatably fitted at the bottom of the movable ring 12. A reciprocating lifting mechanism 14 is provided between one end of the sliding rod 11 and one end of the rotating rod 5.

[0023] Reference Figure 1 In this embodiment, a driver 15 is installed on one side of the vertical lifting machine 7. A chain 16 is installed on the driver 15. One end of the chain 16 passes through the vertical lifting machine 7 and is fixedly connected to the top of the lifting plate 8. Multiple fall arresters are installed inside the vertical lifting machine 7. By using the driver 15, the driver 15 can retract the chain 16, causing the chain 16 to drive the lifting plate 8 to move upward. When the chain 16 is released, the lifting plate 8 will move downward. The fall arresters can prevent the lifting plate 8 and the loading frame 9 from suddenly falling.

[0024] Reference Figure 1In this embodiment, a fixing rod 17 is installed on one side of the loading frame 9, and a stop rod 18 is installed on one side of the vertical lifting machine 7. The stop rod 18 corresponds to the fixing rod 17. When the loading frame 9 moves the fixing rod 17 to the top of the vertical lifting machine 7, the stop rod 18 will squeeze the fixing rod 17, causing the fixing rod 17 to rotate the loading frame 9 and pour the combustion raw material in the loading frame 9 into the storage cylinder 1.

[0025] Reference Figure 2 In this embodiment, multiple support rods 19 are installed between the bottom of the fixed plate 10 and the periphery of the storage cylinder 1. A ladder 20 is provided on one side of the fixed plate 10, and a protective frame 21 is installed on one side of the ladder 20. The support rods 19 support the fixed plate 10, and workers can climb the ladder 20 to the fixed plate 10 for observation. The protective frame 21 provides safety protection for workers climbing the ladder 20.

[0026] Reference Figure 3 The reciprocating lifting mechanism 14 of this embodiment includes a rotating disk 22 mounted on one end of the rotating rod 5 and a connecting rod 23 rotatably engaged with one side of the rotating disk 22. A cavity is provided inside the storage cylinder 1, and the rotating disk 22 and connecting rod 23 are located within the cavity. One end of the connecting rod 23 is rotatably engaged with the bottom end of the sliding rod 11. Through the rotating disk 22, when the motor 4 drives the rotating rod 5 to rotate, the rotating rod 5 drives the auger blades 6 to rotate and transport the combustion raw materials. Simultaneously, the rotating rod 5 drives the rotating disk 22 to rotate, causing the rotating disk 22 to drive one end of the connecting rod 23 to move in a circular motion. The connecting rod 23 pulls and pushes the sliding rod 11, causing the sliding rod 11 to drive the movable ring 12 to reciprocate and lift.

[0027] Reference Figure 4 In this embodiment, the bottom of the movable ring 12 is provided with multiple connecting blocks 24 arranged in a circular array. Multiple shovel blocks 13 are rotatably engaged with the multiple connecting blocks 24. The shovel blocks 13 are L-shaped and have an angled bottom. Through the shovel blocks 13, the L-shaped shovel blocks 13 will pull the combustion raw material, and the angled bottom of the shovel blocks 13 can scoop up the combustion raw material on the inner wall of the storage cylinder 1.

[0028] Working principle: In use, the fuel material is first placed into the loading frame 9. The vertical lifting machine 7 is started, which drives the lifting plate 8 to move upward, causing the loading frame 9 to move upward. When the loading frame 9 moves to the top of the storage cylinder 1, the loading frame 9 can rotate and tilt the fuel material, pouring the fuel material into the storage cylinder 1. When enough fuel material is poured into the storage cylinder 1, the motor 4 is started, which drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 will drive the auger blade 6 to rotate, so that the auger blade 6 conveys the fuel material in the conveying chamber 2 through the conveying pipe 3. The fuel material is continuously pushed by the auger blade 6 in the conveying pipe 3 to the discharge port and discharged into the rotary kiln combustion chamber, providing fuel material for the rotary kiln combustion chamber. At the same time as the rotating rod 5 rotates, the reciprocating lifting mechanism 14 is also activated, which drives the sliding rod 11 to move back and forth. The movement of the sliding rod 11 will drive the movable ring 12 to move, so that the movable ring 12 and multiple shovel blocks 13 can clear the fuel material in the storage cylinder 1.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
