Description

Technical Field

[0001] This utility model relates to the field of coal chute anti-clogging, specifically to a multi-stage coal chute anti-clogging vibration cleaner for coal conveying systems. Background Technology

[0002] The coal conveying pipe connecting the coal bunker and the coal feeder is used to transport raw coal from the coal bunker to the coal feeder and then to the boiler for combustion. However, some coal can easily get stuck when it slides to the corner of the pipe, causing blockage inside the coal drop pipe and affecting the coal conveying efficiency in the coal bunker drop pipe.

[0003] A search revealed that Chinese patent CN223356423U discloses "a coal bunker anti-blocking device for a coal chuting pipe, comprising a coal chuting pipe with an opening at the bottom and a housing at the bottom. Two connecting rods pass through the bottom of the housing, and connecting sleeves are connected to the outer walls of the two connecting rods. This invention uses a motor to drive a rotating rod to rotate, causing an eccentric shaft to continuously strike a connecting plate. Since the vibrating plate and the housing are elastic, the eccentric shaft striking the connecting plate causes the vibrating plate to vibrate continuously. Thus, when coal slides to the corner of the coal chuting pipe, the continuous vibration of the vibrating plate can prevent coal blockage, thereby improving conveying efficiency." However, the following drawbacks still exist: This device relies solely on vibration to prevent coal blockage. However, in actual coal transportation, when the coal has excessive moisture, it easily adheres to the inner wall of the pipe. In this case, relying solely on vibration is insufficient to completely and thoroughly solve the blockage problem caused by coal adhesion.

[0004] To address this, a multi-stage coal chute anti-clogging vibration cleaner for coal conveying systems is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing devices rely solely on a single vibration method to prevent coal blockage. However, in actual coal transportation, when the coal has excessive moisture content, it easily adheres to the inner wall of the pipe. This invention provides a multi-stage coal chute anti-blockage vibration cleaner for coal conveying systems to solve the problems mentioned in the background.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a multi-stage coal chute anti-clogging vibration cleaner for a coal conveying system, including a bend, wherein a cleaning component for cleaning coal adhering inside the bend is provided at the bottom of the bend, and a vibration component for preventing the bend from clogging is provided on one side of the bend in conjunction with the cleaning component. The cleaning assembly includes two sets of connecting pipes bolted to the bottom of the bend, with a first gear disk rotatably connected between the two sets of connecting pipes. A driving component is engaged on one side of the first gear disk, and a cleaning rod is bolted to the inner wall of the first gear disk. The cleaning rod is located inside the bend.

[0007] As a preferred technical solution of this utility model, the vibration component includes a rectangular plate fixedly connected to the outer wall of the bend, a sleeve bolted to one side of the rectangular plate, an air outlet fixedly connected to one end of the sleeve, a connector fixedly installed at the other end of the air outlet, an air disc sleeved on the connector, and a power component fixedly installed at the other end of the sleeve.

[0008] As a preferred technical solution of this utility model, the driving component includes a mounting ring fixedly installed on the outer side wall of the connecting pipe, a servo motor fixedly installed at the bottom of the mounting ring, a rotating shaft installed at the output end of the servo motor, and a second gear disk fixedly installed at the other end of the rotating shaft, the second gear disk meshing with the first gear disk.

[0009] As a preferred technical solution of this utility model, protrusions are fixedly installed on the top and bottom of the first gear disk, and grooves are correspondingly opened on the side walls of the two sets of connecting pipes, with the protrusions engaging in the grooves.

[0010] As a preferred technical solution of this utility model, the power component includes a support ring fixedly disposed on the side wall of the bend, an air compressor fixedly mounted on the top of the support ring, a bellows installed at the output end of the air compressor, and the other end of the bellows fixedly connected to the sleeve.

[0011] As a preferred technical solution of this utility model, the sleeve penetrates through the bend and the rectangular plate and extends into the interior of the bend, and the air outlet is located inside the air disc.

[0012] As a preferred embodiment of this invention, the air disc is located inside the curved tube, and the cleaning rod is located below the air disc.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. With the cleaning component in place, the drive unit will rotate the first gear disc during use. As the first gear disc rotates, the cleaning rod will make a circular motion inside the bend. The cleaning rod will come into contact with the coal material attached to the inner wall of the bend and clean it off by scraping and pushing. This will remove the coal material attached to the inner wall of the bend and remove it from the bend, thereby achieving the purpose of cleaning the coal material attached to the inside of the bend, preventing the coal material from accumulating and causing blockage in the bend, and ensuring the smooth operation of the coal conveying system. 2. With the installed vibration components, during use, the power unit delivers gas into the casing. The gas flows along the casing and is ejected from the gas outlet fixedly connected to the end of the casing. The gas disc generates high-frequency vibration under the impact of the airflow, causing the coal material adhering to the inner wall of the bend to become loose and begin to fall off due to the combined action of vibration and airflow. This vibrates and cleans the coal material inside the bend, preventing blockage and ensuring the smooth operation of the coal conveying system. Attached Figure Description

[0020] like Figure 1 As shown, this embodiment proposes a multi-stage coal chute anti-clogging vibration cleaner for a coal conveying system, including a bend 1. A cleaning component 2 for cleaning coal adhering inside the bend 1 is provided at the bottom of the bend 1, and a vibration component 3 for cooperating with the cleaning component 2 to prevent the bend 1 from clogging is provided on one side of the bend 1. like Figure 2 and Figure 4 As shown, the cleaning component 2 includes two sets of connecting pipes 201 bolted to the bottom of the bend 1. A first gear disk 202 is rotatably connected between the two sets of connecting pipes 201. A driving component 203 is engaged on one side of the first gear disk 202. A cleaning rod 204 is bolted to the inner wall of the first gear disk 202 and is located inside the bend 1. In use, the driving component 203 drives the first gear disk 202 to rotate. As the first gear disk 202 rotates, the cleaning rod 204 makes a circular motion inside the bend 1. The cleaning rod 204 comes into contact with the coal material adhering to the inner wall of the bend 1 and cleans the coal material adhering to the inner wall of the bend 1 by scraping, pushing, etc., so that it falls off the bend 1, thereby achieving the purpose of cleaning the coal material adhering to the inside of the bend 1, preventing the continuous accumulation of coal material and causing blockage of the bend 1, and ensuring the smooth operation of the coal conveying system.

[0021] like Figure 2 and Figure 5As shown, the vibration assembly 3 includes a rectangular plate 301 fixedly connected to the outer wall of the bend 1. A sleeve 302 is bolted to one side of the rectangular plate 301. An air outlet 303 is fixedly connected to one end of the sleeve 302. A connector 304 is fixedly installed at the other end of the air outlet 303. An air disc 305 is sleeved on the connector 304. A power component 306 is fixedly installed at the other end of the sleeve 302. In use, the power component 306 delivers gas into the sleeve 302. The gas flows along the sleeve 302 and is ejected from the air outlet 303 fixedly connected to the end of the sleeve 302. The air disc 305 generates high-frequency vibration under the impact of the airflow, causing the coal material adhering to the inner wall of the bend 1 to become loose and begin to fall off due to the combined action of vibration and airflow. This vibrates and cleans the coal material inside the bend 1, preventing blockage and ensuring the smooth operation of the coal conveying system.

[0022] like Figure 4 and Figure 6 As shown, the driving component 203 includes a mounting ring 2031 fixedly installed on the outer wall of the connecting pipe 201. A servo motor 2032 is fixedly installed at the bottom of the mounting ring 2031. A rotating shaft 2033 is installed at the output end of the servo motor 2032. A second gear disk 2034 is fixedly installed at the other end of the rotating shaft 2033. The second gear disk 2034 meshes with the first gear disk 202. In use, the servo motor 2032 drives the rotating shaft 2033 to rotate. The rotation of the rotating shaft 2033 synchronously drives the second gear disk 2034 to rotate. The rotation of the second gear disk 2034 drives the first gear disk 202 to rotate. The rotation of the first gear disk 202 drives the cleaning rod 204 to make a circular motion inside the bend 1, cleaning the coal material attached to the inner wall of the bend 1 and preventing the bend 1 from becoming blocked.

[0023] like Figure 6 As shown, protrusions 4 are fixedly installed on the top and bottom of the first gear disk 202, and grooves are correspondingly opened on the side walls of the two sets of connecting pipes 201, with the protrusions 4 engaging in the grooves. The grooves restrict and guide the protrusions 4, ensuring that the first gear disk 202 remains stable during rotation and does not shift or shake, thus ensuring the stability and reliability of the cleaning operation.

[0024] like Figure 3 and Figure 5As shown, the power component 306 includes a support ring 3061 fixedly disposed on the side wall of the bend 1. An air compressor 3062 is fixedly mounted on the top of the support ring 3061. A bellows 3063 is fitted onto the output end of the air compressor 3062, and the other end of the bellows 3063 is fixedly connected to the sleeve 302. Compressed high-pressure air is discharged from the output end of the air compressor 3062 and enters the bellows 3063. After passing through the bellows 3063, the air enters the sleeve 302 fixedly connected to it, and then flows along the sleeve 302, finally reaching the air outlet 303 and acting on the air disc 305, causing the air disc 305 to generate high-frequency vibration, thereby cleaning the coal material adhering to the bend 1 and preventing the bend 1 from becoming blocked.

[0025] like Figure 5 As shown, the sleeve 302 passes through the bend 1 and the rectangular plate 301 and extends into the interior of the bend 1. The air outlet 303 is located inside the air disc 305. The high-pressure gas generated by the air compressor 3062 is delivered to the sleeve 302 through the bellows 3063. The gas flows along the sleeve 302 and is finally ejected from the air outlet 303. Under the impact of the airflow, the air disc 305 will generate high-frequency and regular vibrations, which will cause the coal material adhering to the inner wall of the bend 1 to fall off.

[0026] like Figure 5 As shown, the air disc 305 is located inside the bend 1, and the cleaning rod 204 is located below the air disc 305. The vibration of the air disc 305 loosens the coal, and the cleaning rod 204 scrapes the coal adhering to the inside of the bend 1. The air disc 305 and the cleaning rod 204 work together to prevent the bend 1 from becoming blocked and to ensure the smooth operation of the coal conveying system.

[0027] Specifically, when the multi-stage coal chute anti-clogging vibration cleaner of this coal conveying system is in use: the power component 306 delivers gas to the sleeve 302, the gas flows along the sleeve 302 and is ejected from the air outlet 303 fixedly connected to the end of the sleeve 302. The air disc 305 generates high-frequency vibration under the impact of the airflow, causing the coal material adhering to the inner wall of the bend 1 to become loose and begin to fall off due to the combined action of vibration and airflow. This vibrates and cleans the coal material inside the bend 1, preventing blockage. The drive component 203 drives the first gear disc 202 to rotate. As the first gear disc 202 rotates, the cleaning rod 204 will make a circular motion inside the bend 1. The cleaning rod 204 will contact the coal material adhering to the inner wall of the bend 1 and clean it off by scraping and pushing, thus achieving the purpose of cleaning the coal material adhering to the inside of the bend 1, preventing the continuous accumulation of coal material and causing blockage of the bend 1, and ensuring the smooth operation of the coal conveying system.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
