Description
Technical Field
[0001] This invention relates to the field of feeding grate technology, and in particular to a feeding grate with anti-jamming function. Background Technology
[0002] Currently, waste incinerators have become an important piece of equipment for waste treatment. Typically, when a waste incinerator is in use, a feeding grate pushes the municipal solid waste entering from the feed chute into the combustion chamber for combustion. The grate bars are commonly used combustion components in the combustion chamber; the fixed, sliding, and tilting grate bars respectively support, propel, and tilt the municipal solid waste within the incinerator.
[0003] In existing technologies, due to the influence of the gravity of the municipal solid waste itself, the feeding grate is prone to lifting, shaking, and deviating at the tail end during the process of pushing the municipal solid waste.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0034] As described in the background section, the feeding grate is prone to tail lifting, shaking, and deviation during the process of pushing municipal solid waste. This can lead to squeezing, friction, and jamming at the tail of the feeding grate, preventing it from pushing material back and forth normally and causing many difficulties in production operations.
[0035] To solve this technical problem, the present invention provides a feeding grate with anti-jamming function, which is applied to a waste incinerator.
[0036] For details, please refer to Figures 1-6 The feed grate with anti-jamming function specifically includes:
[0037] The outer frame 1 has a movable frame 2 inside it, and a hydraulic telescopic mechanism 3 for pushing the movable frame 2 to move is also provided inside the outer frame 1.
[0038] The lifting beam 4 is located at the lower inner side of the outer frame 1 and is used for guiding and limiting the movement of the movable frame 2.
[0039] The anti-tilting beam 5 is located on the upper inner side of the outer frame 1 and is used for guiding and limiting the movement of the movable frame 2.
[0040] The guide rail 6 is located on the inner side wall of the outer frame 1 and is used for guiding and limiting the movement of the movable frame 2.
[0041] The bottom of the mobile frame 2 is provided with a first guide wheel 7 that cooperates with the lifting beam 4, the top of the mobile frame 2 is provided with a second guide wheel 8 that cooperates with the anti-tilting beam 5, and the side of the mobile frame 2 is provided with a third guide wheel 9 that cooperates with the guide side rail 6.
[0042] The feeding grate with anti-jamming function provided by this invention significantly improves motion stability through the combination of multi-dimensional guidance and rolling structure. The three-way guiding mechanism of bottom support beam 4, top anti-tilting beam 5 and side guide rail 6, together with the synergistic effect of guide rail and rolling components, converts sliding friction into rolling friction. This design can evenly distribute the load and accurately limit the displacement trajectory of the moving frame 2, avoiding its tilting, deviation or shaking, and fundamentally reducing the risk of jamming caused by mechanical misalignment.
[0043] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0044] Example 1:
[0045] Please refer to Figures 1-6 A feeding grate with anti-jamming function, comprising:
[0046] The outer frame 1 contains a movable frame 2, and a hydraulic telescopic mechanism 3 for pushing the movable frame 2. The hydraulic telescopic mechanism 3 achieves smooth movement of the movable frame 2 within the outer frame 1 by precisely controlling the telescopic amount. A feeding hopper 12 is located at the end of the outer frame 1 for guiding the disposal of waste.
[0047] The lifting beam 4 is located at the lower inner side of the outer frame 1 and is used for guiding and limiting the movement of the movable frame 2.
[0048] Specifically, the lifting beam 4 includes a first beam 41 and a second beam 42. The first beam 41 is located at the lower middle part of the mobile frame 2, and there are two second beams 42, which are located on the lower sides of the mobile frame 2 respectively. This layout can evenly distribute the weight of the mobile frame 2 and ensure that the mobile frame 2 remains stable during movement.
[0049] The anti-tilting beam 5 is located on the upper inner side of the outer frame 1 and is also used for guiding and limiting the movement of the mobile frame 2. During the movement of the mobile frame 2, the anti-tilting beam 5 can effectively prevent the rear end of the mobile frame 2 from tilting upward, ensuring the accuracy of its movement trajectory.
[0050] The guide side rail 6 is located on the inner side wall of the outer frame 1 and is used to guide and limit the movement of the movable frame 2. During the movement of the movable frame 2, the guide side rail 6 can effectively prevent the movable frame 2 from deviating to the left or right and ensure the accuracy of its movement trajectory.
[0051] The bottom of the mobile frame 2 is equipped with a first guide wheel 7 that cooperates with the supporting beam 4. Specifically, the first guide wheel 7 includes a limiting wheel 71 and a load-bearing wheel 72. The limiting wheel 71 is fixedly connected to the mobile frame 2 and is tactilely connected to the first beam 41. There are multiple limiting wheels 71, which are arranged along the length of the first beam 41. Through the tactile connection between the limiting wheels 71 and the first beam 41, the mobile frame 2 can move smoothly on the first beam 41 and play a certain limiting role. The load-bearing wheel 72 is fixedly connected to the second beam 42 and is tactilely connected to the bottom of the mobile frame 2. There are also multiple load-bearing wheels 72, which are arranged along the length of the second beam 42. The load-bearing wheels 72 mainly bear the weight of the mobile frame 2 to ensure that the mobile frame 2 will not jam or cause other problems due to excessive weight during movement.
[0052] Furthermore, a first T-shaped limiting guide rail 10 is fixedly connected to the upper end of the first beam 41, and the limiting wheel 71 is rolledly connected to the first beam 41 through the first T-shaped limiting guide rail 10. The design of the first T-shaped limiting guide rail 10 can further restrict the movement direction of the limiting wheel 71, prevent it from detaching from the first beam 41, and improve the stability of the movement of the moving frame 2.
[0053] Furthermore, the top of the movable frame 2 is provided with a second guide wheel 8 that cooperates with the anti-tilting beam 5. The lower end of the anti-tilting beam 5 is fixedly connected with a second T-shaped limiting guide rail 11. The second guide wheel 8 is in rolling connection with the anti-tilting beam 5 through the second T-shaped limiting guide rail 11. The second T-shaped limiting guide rail 11 can guide the movement direction of the second guide wheel 8 and prevent the movable frame 2 from tilting upward, ensuring that the movable frame 2 is stable in the vertical direction.
[0054] Furthermore, the side of the movable frame 2 is provided with a third guide wheel 9 that cooperates with the guide side rail 6, which effectively prevents the movable frame 2 from shifting left or right and ensures the accuracy of its movement trajectory.
[0055] Through the above structural design, the lifting beam 4, the anti-tilting beam 5, and the guide side rail 6 guide and limit the moving frame 2 from the bottom, top, and side directions, respectively. With the rolling connection between each guide wheel and the corresponding guide rail, the moving frame 2 can move smoothly and steadily within the outer frame 1, effectively avoiding jamming and improving the working efficiency and reliability of the feeding grate.
[0056] Example 2:
[0057] The feed grate with anti-jamming function provided in Example 1 has been further optimized, specifically, as follows: Figures 7-8 As shown, the inner side of the guide rail 6 is provided with a vertical movement limiting groove 61 along the length direction, and the inner wall of the vertical movement limiting groove 61 is provided with a horizontal movement limiting groove 62 along the length direction, which provides precise guidance for the side movement of the moving frame 2; the third guide wheel 9 includes a fixed plate 90, which is fixedly connected to the moving frame 2. The side of the fixed plate 90 is rotatably connected with a transverse guide wheel 91 and a longitudinal guide wheel 92, respectively. The transverse guide wheel 91 is located inside the vertical movement limiting groove 61, and the longitudinal guide wheel 92 extends to the inside of the horizontal movement limiting groove 62.
[0058] Through the above structural design, the transverse guide wheel 91 and the longitudinal guide wheel 92 can roll within the vertical and horizontal movement limiting grooves 61 and 62 respectively, further precisely limiting the movement trajectory of the moving frame 2 in the lateral direction. During the movement of the moving frame 2, the transverse guide wheel 91 prevents the moving frame 2 from shifting in the forward and backward direction perpendicular to the movement direction, while the longitudinal guide wheel 92 prevents the moving frame 2 from swaying in the left and right direction, thereby ensuring the movement accuracy of the moving frame 2 in three-dimensional space and further improving the anti-jamming performance of the feeding grate. Through the above structural design, the movement of the moving frame 2 is more stable and reliable, reducing jamming problems caused by unstable movement.
[0059] Example 3:
[0060] The feed grate with anti-jamming function provided in Example 2 has been further optimized, specifically, as follows: Figure 8As shown, a cleaning block 93 is fixedly connected to the side of the movable frame 2, near the fixed plate 90. The cleaning block 93 is located inside the vertical movement limiting groove 61. A V-shaped groove is formed at the end of the cleaning block 93 away from the fixed plate 90. This V-shaped groove design allows the upper and lower ends of the V-shaped groove at the end of the cleaning block 93 to contact the top and bottom of the inner side of the vertical movement limiting groove 61, respectively, during movement. A protrusion 94 is fixedly connected to the middle of the cleaning block 93. The protrusion 94 extends to the inner side of the horizontal movement limiting groove 62 and can contact the inner wall of the horizontal movement limiting groove 62. The cleaning block 93 is fixedly connected to the movable frame 2 by fixing bolts 95.
[0061] Through the above structural design, during the movement of the moving frame 2, the upper and lower ends of the V-shaped groove at the end of the cleaning block 93 contact and scrape the top and bottom of the inner side of the upper and lower moving limit groove 61, respectively, thereby removing the attached materials on the top and bottom of the inner side of the upper and lower moving limit groove 61. At the same time, as the protrusion 94 moves along with the cleaning block 93, it simultaneously scrapes the attached materials on the inner wall of the left and right moving limit groove 62. These attached materials may be dust, impurities, etc. generated during the feeding process. If they are not cleaned in time, they will gradually accumulate, affecting the smooth movement of the moving frame 2 and even causing jamming. The design of the cleaning block 93 and the protrusion 94 can effectively solve this problem, keep the upper and lower moving limit groove 61 and the left and right moving limit groove 62 clean, further improve the anti-jamming performance of the feeding grate, and extend the service life of the equipment.
