Description

[Technical Field]

[0001] The present invention relates to the field of boilers, and more particularly to a boiler clinker treatment and recovery device. [Background technology]

[0002] Boiler clinker is a major solid waste generated during the operation of coal-fired boilers. Its composition is complex, its hardness is heterogeneous, and it often contains a certain amount of metal impurities or sintered agglomerates. To utilize it as a resource, it is typically crushed and adjusted to a specific particle size required for subsequent sorting, building material production, or landfill disposal. However, in actual operation, blockages at the feed port of existing crushers are common when processing boiler clinker. This is mainly due to the irregular shape of the clinker, which causes bridging at the feed chute or the inlet of the crushing chamber, resulting in blockages and necessitating equipment shutdowns for cleaning. Frequent blockages not only reduce processing efficiency, but also increase the manual cleaning burden and equipment maintenance costs. Furthermore, they can lead to equipment overload, damage, and even safety accidents, severely impacting the continuous and stable operation of the entire clinker processing system. Summary of the Invention

[0003] Therefore, the technical problem that this invention aims to solve is that the irregular shape of the clinker mainly causes a bridging phenomenon at the entrance of the feed chute or crushing chamber, causing clogging and forcing the equipment to be shut down for cleaning work.

[0004] The above technical problems are solved by the following technical solutions. The present invention provides a boiler clinker treatment and recovery device, the device comprising: A crushing box having a through hole formed therein and gradually contracting inward from the middle to the bottom of the crushing box; a drive member used to provide power; a driving roller rotatably connected to the inside of the crushing box; a driven roller rotatably connected to the inside of the crushing box and having the same structure as the driven roller; a guide block fixedly connected to the inside of the crushing box, a vibration plate rotatably connected to the top of the guide block, and a clogging prevention member including trigger blocks fixedly connected to both ends of the driving roller and the driven roller; Specifically, when the driving member is operated, the driving member drives the main roller and the driven roller to rotate relative to each other inside the crushing box, thereby crushing the clinker. The crushed clinker falls into a collection box previously provided at the bottom of the crushing box. In addition, as the main roller and the driven roller rotate, the trigger block is rotated, and the trigger block drives a vibrating plate to vibrate intermittently at the top of the guide block, thereby discharging the clinker inside and preventing blockages caused by bridging.

[0005] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, a feed pipe is provided at the top of the crushing box, and a coupler is fixedly connected to the bottom of the feed pipe, and the coupler 12 is fitted to the top of the crushing box and used to connect the feed pipe and the crushing box.

[0006] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, the driving member includes a motor, a driving gear fixedly connected to the output end of the motor, and a toothed belt attached and engaged with the driving gear, and by operating the motor, the driving gear rotates, thereby rotating the toothed belt engaged with the driving gear.

[0007] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, a double gear is provided at one end of the driving roller, and a driven gear is provided at one end of the driven roller, the inner toothed disc of the double gear meshes with the driven gear, and the outer toothed disc of the double gear meshes with the toothed belt, the rotation of the toothed belt rotates the double gear, which in turn rotates the driven gear meshing with it, and the rotation of the double gear and the driven gear rotates the driving roller and the driven roller relative to each other to crush the clinker.

[0008] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, anti-detachment rings are fixedly connected to both sides of the drive gear, and anti-detachment rings are fixedly connected to both sides of the outer toothed disc of the double gear, and the anti-detachment rings restrain the toothed belt hanging on the outside of the double gear and the drive gear, preventing the toothed belt from falling off.

[0009] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, the guide block is gradually inclined downward toward the gap between the driving roller and the driven roller, and the inclined design of the guide block guides the clinker to fall reliably between the driving roller and the driven roller.

[0010] In a preferred embodiment of the boiler clinker treatment and recovery device of the present invention, the vibrating plate includes a rotating shaft rotatably connected to the inside of the guide block, an inclined plate fixedly connected to the outside of the rotating shaft, and an inclined rod fixedly connected to both ends of the rotating shaft, and the guide block provides a support function for the inclined plate; Specifically, when the tilt rod is pressed, it rotates the rotary shaft, thereby rotating the tilt plate outside the rotary shaft; when the tilt rod is not pressed, the tilt plate returns to its original position and adheres to the surface of the guide block under the pressure of the gravity of the clinker. When the tilt rod is continuously subjected to intermittent pressure, it generates a vibration effect on the tilt plate, achieving the effect of clinker clearance.

[0011] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, the trigger block includes a ring fixedly connected to both ends of the driving roller and the driven roller, and a protruding block fixedly connected to the outside of the ring, and the rotation of the driving roller and the driven roller causes the ring to rotate, thereby rotating the protruding block located outside the ring, and the rotating protruding block can intermittently press the tilting rod and generate vibrations in the tilting plate.

[0012] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, the protruding blocks on the ring attached to the outside of the driving roller and the protruding blocks on the ring attached to the outside of the driven roller are offset from each other in the circumferential position. Due to this offset design, the two inclined plates vibrate at different frequencies, which further provides a permeating effect on the clinker.

[0013] In a preferred embodiment of the boiler clinker treatment and recovery device described in the present invention, the device further includes a support base, wherein the crushing box is attached to the top of the support base by bolts, and the motor is attached to the top of the support base.

[0014] The beneficial effects of this invention are as follows: The rotating protruding block periodically presses the tilting rod and continuously vibrates the tilting plate, effectively breaking up the bridges formed by clinker on the surface of the guide block and fundamentally preventing the feed port from being blocked. At the same time, the protruding blocks on both roller sides are offset, allowing the two tilting plates to vibrate alternately, further enhancing drainage efficiency and reliability. This structure effectively reduces the frequency of cleaning work due to equipment shutdowns and maintenance costs, improves the continuity and stability of the crushing process, and ensures the efficient operation of the entire clinker recycling system.

[0016] In order to enable those skilled in the art to better understand the present invention, the following will describe the present invention in more detail in combination with specific embodiments and drawings.

[0017] The terms used in this specification are general terms currently widely used in the art, taking into consideration the functions of the specification. However, these terms may be changed according to the intentions of those skilled in the art, existing practices, or the development of new technologies in the art. Furthermore, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the specification. Therefore, the terms used in this specification should not be understood as simple names, but should be understood based on the meaning of the terms and the overall description of the specification.

[0018] 1 to 7, the present embodiment provides a boiler clinker treatment and recovery device, the device comprising: A crushing box 1, which has a through hole provided therein and gradually shrinks inward from the middle to the bottom of the crushing box 1; a driving member 2 used to provide power; A driving roller 3 rotatably connected inside the crushing box 1; A driven roller 4 is rotatably connected to the inside of the crushing box 1 and has the same structure as the driven roller 3; a guide block 51 fixedly connected to the inside of the crushing box 1, a vibration plate 52 rotatably connected to the top of the guide block 51, and a clogging prevention member 5 including trigger blocks 53 fixedly connected to both ends of the driving roller 3 and the driven roller 4; Specifically, when the driving member 2 is operated, the driving member 2 drives the driving roller 3 and the driven roller 4 to rotate relative to each other inside the crushing box 1, thereby crushing the clinker. The crushed clinker falls into a collection box previously installed at the bottom of the crushing box 1. In addition, as the driving roller 3 and the driven roller 4 rotate, the trigger block 53 rotates, and the trigger block 53 drives the vibration plate 52 to vibrate intermittently at the top of the guide block 51, thereby discharging the clinker inside and preventing blockages caused by bridging.

[0019] A supply pipe 11 is provided at the top of the crushing box 1, and a coupler 12 is fixedly connected to the bottom of the supply pipe 11. The coupler 12 is fitted to the top of the crushing box 1 and is used to connect the supply pipe 11 to the crushing box 1.

[0020] The drive member 2 includes a motor 21, a drive gear 22 fixedly connected to the output end of the motor 21, and a toothed belt 23 attached to and engaged with the drive gear 22. By operating the motor 21, the drive gear 22 rotates, causing the toothed belt 23 engaged with the drive gear 22 to rotate.

[0021] A double gear 31 is provided at one end of the driving roller 3, and a driven gear 41 is provided at one end of the driven roller 4. The inner toothed disc of the double gear 31 meshes with the driven gear 41, and the outer toothed disc of the double gear 31 meshes with the toothed belt 23. The rotation of the toothed belt 23 rotates the double gear 31, which in turn rotates the driven gear 41 that meshes with it. The rotation of the double gear 31 and the driven gear 41 rotates the driving roller 3 and the driven roller 4 relative to each other, thereby crushing the clinker.

[0022] As one embodiment provided, as shown in Figures 1 to 7, anti-detachment rings 100 are fixedly connected to both sides of the drive gear 22, and anti-detachment rings 100 are fixedly connected to both sides of the outer toothed disk of the double gear 31, and these anti-detachment rings 100 restrain the position of the toothed belt 23 hanging on the outside of the double gear 31 and the drive gear 22, preventing the toothed belt 23 from falling off.

[0023] As an example, as shown in FIGS. 4 and 5, the guide block 51 is gradually inclined downward toward the gap between the driving roller 3 and the driven roller 4. Due to the inclined design of the guide block 51, the clinker is guided and falls reliably between the driving roller 3 and the driven roller 4.

[0024] The vibration plate 52 includes a rotary shaft 521 rotatably connected to the inside of the guide block 51, an inclined plate 522 fixedly connected to the outside of the rotary shaft 521, and an inclined rod 523 fixedly connected to both ends of the rotary shaft 521, and the guide block 51 provides a support function for the inclined plate 522. Specifically, when the tilting rod 523 is pressed, it rotates the rotating shaft 521, thereby rotating the tilting plate 522 outside the rotating shaft 521; when the tilting rod 523 is not pressed, the tilting plate 522 returns to its original position and adheres to the surface of the guide block 51 under the pressure of the gravity of the clinker. When the tilting rod 523 is continuously and intermittently pressed, it generates a vibration effect on the tilting plate 522, thereby achieving the effect of clinker clearance.

[0025] The trigger block 53 includes a ring 531 fixedly connected to both ends of the driving roller 3 and the driven roller 4, and a protruding block 532 fixedly connected to the outside of the ring 531. The rotation of the driving roller 3 and the driven roller 4 rotates the ring 531, thereby rotating the protruding block 532 located outside the ring 531. The rotating protruding block 532 can intermittently press the tilting rod 523, generating vibrations in the tilting plate 522.

[0026] The protruding blocks 532 on the ring 531 attached to the outside of the driving roller 3 and the protruding blocks 532 on the ring 531 attached to the outside of the driven roller 4 are offset from each other in the circumferential direction. This offset design allows the two inclined plates 522 to vibrate at different frequencies, further providing a permeating effect on the clinker.

[0027] In one embodiment provided, as shown in FIGS. 1 to 3, the crushing box 1 is attached to the top of the support base 6 by bolts, and the motor 21 is attached to the top of the support base 6.

[0028] From the above, motor 21 is started to rotate drive gear 22, which in turn rotates toothed belt 23 to rotate double gear 31. The inner toothed disc of double gear 31 meshes with driven gear 41, thereby rotating drive roller 3 and driven roller 4 relative to each other and crushing clinker. As drive roller 3 and driven roller 4 rotate, ring 531 and protruding block 532 attached to both ends of drive roller 3 and driven roller 4 rotate accordingly. Protruding block 532 intermittently presses against tilting rod 523, forcing rotation of rotating shaft 521 and causing vibration of tilting plate 522. After protruding block 532 is released, tilting plate 522 returns to its original position under the gravity of the clinker and adheres to the surface of guide block 51. The continuous and intermittent pressure from protruding block 532 creates a vibration effect on tilting plate 522, effectively breaking down the bridge structure formed by clinker on the surface of guide block 51 and preventing blockage of the feed port. Furthermore, the protruding blocks 532 on both sides of the driving roller 3 and the driven roller 4 are offset in the circumferential direction, causing the two inclined plates 522 to vibrate at different frequencies, further enhancing the permeability effect. The crushing box 1 has a structure that gradually contracts inward from the middle to the bottom, which helps guide the material to be treated, and the inclined design of the guide block 51 ensures that the clinker falls reliably between the two rollers. The entire device uses mechanical interlocking to achieve automatic blockage prevention, significantly improving treatment efficiency, reducing the frequency of cleaning work due to equipment shutdowns, and ensuring continuous, stable operation of the system.

[0029] Finally, it should be pointed out that the methods and apparatus described in detail above are merely examples, and that those skilled in the art can make many modifications to these examples without departing from the scope of the present invention.
