[0002] With the severe challenges of global energy structure transformation and climate change, energy conservation, emission reduction, and green transformation have become inevitable trends for the cement industry, which is one of the traditional industries with high energy consumption and high emissions. In recent years, cement companies have been gradually increasing the proportion of alternative fuels used to reduce the consumption of fossil fuels.
[0003] However, when cement kilns co-process alternative fuels, problems such as fuel accumulation and blockage, unstable and inefficient feeding systems, and uneven material dispersion occur during the feeding process, affecting the supply of alternative fuels and their combustion effect in the kiln. Utility Model Content
[0004] To address the aforementioned problems such as fuel accumulation and blockage, unstable and inefficient feeding system, and uneven material dispersion, this utility model provides a cement kiln alternative fuel feeding device.
[0005] The present invention adopts the following technical solution:
[0006] A cement kiln alternative fuel feeding device includes a discharge pipe. Two cam components are symmetrically arranged at the lower end of the side wall of the discharge pipe. A buffer component is movably arranged at the bottom of the inner wall of the discharge pipe, and the lower end of the buffer component slides in cooperation with the outer wall of the cam component. Two internally threaded pipes are symmetrically arranged at the upper end of the side wall of the discharge pipe. A fixing plate is fixedly arranged on the side wall of the discharge pipe, and the fixing plate is connected to the internally threaded pipes by a torsion spring. A dispersing rod is movably arranged at the top of the inner wall of the discharge pipe, and the two ends of the dispersing rod are respectively threaded into the two internally threaded pipes. Steel cables are fixedly arranged at both ends of the buffer component, and the upper ends of the steel cables pass through the discharge pipe and are wound around the internally threaded pipes.
[0007] The above technical solution facilitates the feeding of alternative fuel into the cement kiln through the feed pipe, and the rotation of the cam component facilitates the control of the up-and-down movement of the buffer component. As the buffer component moves, it helps to buffer and disperse the alternative fuel, thereby reducing the impact of the alternative fuel on the cement kiln.
[0008] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, two vertical grooves are symmetrically opened on the bottom wall of the inner wall of the material drop pipe, and the two ends of the buffer are respectively inserted into the two vertical grooves and slide in cooperation with the inner wall of the vertical grooves.
[0009] The above technical solution uses two vertical slots to limit the movement of the buffer component, allowing it to move only up and down.
[0010] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, the cam component includes a motor and a cam disk. The motor is fixedly installed on the outer wall of the discharge pipe, the rotating shaft of the motor passes through the discharge pipe and is fixedly connected to the cam disk, and the cam disk is located in the vertical groove and slides in cooperation with the inner wall of the vertical groove.
[0011] The above technical solution allows the motor to easily drive the cam disk to rotate, and as the cam disk rotates, it is easy to control the movement of the buffer component along the inner wall of the vertical groove.
[0012] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, both ends of the buffer are fixedly provided with sliders. The sliders are located in the vertical groove and slide in cooperation with the inner wall of the vertical groove. The sliders are connected to the inner bottom wall of the vertical groove by a spring. A round rod is fixedly provided on the bottom surface of the slider, and the lower end of the round rod slides in cooperation with the outer wall of the cam plate.
[0013] With the above technical solution, as the motor drives the cam disk to rotate, the round rod slides along the outer wall of the cam disk, thereby causing the round rod to drive the buffer to move up and down.
[0014] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, the buffer element is in the shape of an inverted V, and the top surface of the buffer element has several through holes.
[0015] The above technical solution allows the buffer to cushion and disperse the alternative fuel, while the through-holes allow the alternative fuel to fall into the cement kiln through the buffer.
[0016] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, an annular groove is provided on the internally threaded pipe, one end of the steel cable is fixedly connected to the slider, and the other end of the steel cable is wound and arranged in the annular groove.
[0017] With the above technical solution, when the buffer moves the slider, it is easy to move the steel cable synchronously, and the steel cable can be used to pull the internal threaded tube to rotate.
[0018] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, both ends of the dispersing rod are provided with external threads adapted to the internal threaded pipe, and two auxiliary rods are symmetrically arranged on the outer wall of the dispersing rod, with both ends of the two auxiliary rods being movably inserted into the inner wall of the discharge pipe.
[0019] With the above technical solution, when the internally threaded tube rotates, the disintegrating rod moves along the axial direction of the internally threaded tube, and the auxiliary rod moves synchronously as the disintegrating rod moves.
[0020] Optionally, in the above-mentioned cement kiln alternative fuel feeding device, the outer walls of both the auxiliary rod and the dispersing rod are fixedly provided with a number of breaking nails.
[0021] The above technical solution allows the dispersing rod to easily move the auxiliary rod and the breaking nail, thereby dispersing the alternative fuel through the breaking nail.
[0022] In summary, this utility model has at least one of the following beneficial effects:
[0023] When the buffer moves, it pulls the steel cable down. At this time, the steel cable pulls the internal threaded tube to rotate and causes the dispersing rod to move inside the discharge tube, thereby continuously dispersing the alternative fuel inside the discharge tube and reducing the possibility of the alternative fuel clogging the discharge tube.
[0024] The rotation of the cam component facilitates the control of the up-and-down movement of the buffer component. As the buffer component moves, it helps to cushion and disperse the alternative fuel, thereby reducing the possibility of the alternative fuel exerting a large impact on the cement kiln and improving the uniformity of material dispersion.

[0029] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0030] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a cement kiln alternative fuel feeding device, including a discharge pipe 1, which is installed on the cement kiln to allow fuel to fall into the cement kiln; two cam members 2 are symmetrically arranged at the lower end of the side wall of the discharge pipe 1, and a buffer member 3 is movably arranged at the bottom of the inner wall of the discharge pipe 1. The lower end of the buffer member 3 slides with the outer wall of the cam member 2, and two vertical grooves 11 are symmetrically opened on the bottom wall of the inner wall of the discharge pipe 1. The two ends of the buffer member 3 are respectively inserted into the two vertical grooves 11 and slide with the inner wall of the vertical grooves 11. The two vertical grooves 11 facilitate the limiting of the buffer member 3, so that the buffer member 3 can only move up and down, thereby buffering the alternative fuel through the buffer member 3.
[0031] The cam component 2 includes a motor 21 and a cam disk 22. The motor 21 is fixedly mounted on the outer wall of the discharge pipe 1. The rotating shaft of the motor 21 passes through the discharge pipe 1 and is fixedly connected to the cam disk 22. The cam disk 22 is located in the vertical groove 11 and slides in cooperation with the inner wall of the vertical groove 11. The motor 21 can easily drive the cam disk 22 to rotate. As the cam disk 22 rotates, it is easy to control the buffer component 3 to move along the inner wall of the vertical groove 11, thereby buffering the alternative fuel through the buffer component 3.
[0032] Both ends of the buffer 3 are fixedly provided with sliders 31. The sliders 31 are located in the vertical groove 11 and slide in cooperation with the inner wall of the vertical groove 11. The sliders 31 are connected to the inner bottom wall of the vertical groove 11 by a spring 32. A round rod 33 is fixedly provided on the bottom surface of the slider 31. The lower end of the round rod 33 slides in cooperation with the outer wall of the cam disk 22. The cooperation between the slider 31 and the vertical groove 11 facilitates the limiting of the buffer 3, thereby increasing the stability of the buffer 3 when it moves. As the motor 21 drives the cam disk 22 to rotate, the round rod 33 slides along the outer wall of the cam disk 22, thereby causing the round rod 33 to drive the buffer 3 to move up and down.
[0033] The buffer element 3 is in the shape of an inverted V. Several through holes 34 are provided on the top surface of the buffer element 3. The buffer element 3 facilitates the buffering of the alternative fuel and disperses the alternative fuel. The alternative fuel can fall into the cement kiln through the through holes 34.
[0034] Two internally threaded tubes 4 are symmetrically arranged at the upper end of the side wall of the discharge tube 1. A fixing plate 5 is fixedly installed on the side wall of the discharge tube 1. The fixing plate 5 is connected to the internally threaded tube 4 by a torsion spring 6. When the internally threaded tube 4 rotates, the torsion spring 6 is torsionally deformed, and the internally threaded tube 4 is easily rotated and reset through the torsion spring 6.
[0035] A dispersing rod 7 is movably installed at the top of the inner wall of the discharge pipe 1. The two ends of the dispersing rod 7 are threaded into two internally threaded pipes 4 respectively. Both ends of the dispersing rod 7 are provided with external threads that are compatible with the internally threaded pipes 4. Two auxiliary rods 71 are symmetrically arranged on the outer wall of the dispersing rod 7. Both ends of the two auxiliary rods 71 are movably inserted into the inner wall of the discharge pipe 1. The two auxiliary rods 71 cooperate to limit the dispersing rod 7. When the internally threaded pipe 4 rotates, the dispersing rod 7 moves along the axial direction of the internally threaded pipe 4. As the dispersing rod 7 moves, it drives the auxiliary rods 71 to move synchronously, thereby reducing the possibility of alternative fuel clogging the discharge pipe 1.
[0036] Several crushing nails 72 are fixedly installed on the outer walls of both the auxiliary rod 71 and the dispersing rod 7. The dispersing rod 7 facilitates the movement of the auxiliary rod 71 and the crushing nails 72, and the crushing nails 72 disperse the alternative fuel, thereby reducing the possibility of the alternative fuel clogging the feed pipe 1.
[0037] Both ends of the buffer 3 are fixedly provided with steel cables 8. The upper end of the steel cable 8 passes through the feed pipe 1 and is wound around the internal threaded pipe 4. The internal threaded pipe 4 has an annular groove 41. One end of the steel cable 8 is fixedly connected to the slider 31, and the other end of the steel cable 8 is wound around the annular groove 41. The annular groove 41 facilitates the storage of the steel cable 8. When the buffer 3 drives the slider 31 to move, it facilitates the synchronous movement of the steel cable 8, and the steel cable 8 facilitates the rotation of the internal threaded pipe 4.
[0038] Working principle: When using this alternative fuel feeding device, the alternative fuel is easily fed into the cement kiln through the feed pipe 1. The rotation of the cam component 2 facilitates the up and down movement of the buffer component 3. As the buffer component 3 moves, it helps to buffer the alternative fuel and disperse it, thereby reducing the possibility of the alternative fuel having a large impact on the cement kiln.
[0039] When the buffer 3 moves down, it pulls the steel cable 8 down. At this time, the steel cable 8 pulls the internal threaded tube 4 to rotate and causes the dispersing rod 7 to move inside the discharge tube 1. As the internal threaded tube 4 rotates, it causes the torsion spring 6 to twist and deform.
[0040] When the buffer 3 moves upward, the steel cable 8 loses tension. At this time, the torsion spring 6 drives the internal threaded tube 4 to rotate and reset, thereby causing the dispersing rod 7 to move in the opposite direction. This process is repeated to continuously disperse the alternative fuel in the discharge pipe 1, thereby reducing the possibility of the alternative fuel clogging the discharge pipe 1.
[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
