Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to an automatic monitoring device for coal blockage of a coal conveying belt. Background Technique

[0002] Power plants use coal as a raw material for power generation and use belt conveyors to transport coal. The coal is often small coal blocks and pulverized coal, which are transferred to other places through a coal dropping pipe. In actual production, the machine is often shut down due to the blockage of the coal dropping pipe. The reasons for the blockage are that the volume of coal blocks is relatively large, blocking the coal dropping pipe, and the high humidity of pulverized coal causes adhesion in the coal dropping pipe, resulting in blockage. Continuing to transport coal after the coal dropping pipe is blocked will cause coal to overflow, affecting the coal transport environment, and manual cleaning is troublesome.

[0003] In the prior art, as disclosed in Chinese Patent No.: CN214609973U, a coal blockage monitoring device for a power plant coal conveying belt is disclosed, including a conveyor and a coal dropping pipe arranged at one end of the conveyor.

[0030] Embodiment 2 is as Figures 1 to 4 shown. On one side near the top of the collecting frame 506, two second fixing blocks 601 are symmetrically and fixedly installed. On the opposite sides of the two second fixing blocks 601, a connecting pipe 602 is fixedly embedded. On the outer surface of the connecting pipe 602, a plurality of air outlet pipes 603 are fixedly embedded at equal intervals. On the other side near the top of the collecting frame 506, a high-pressure blower 6 is fixedly installed. The air outlet end of the high-pressure blower 6 is fixedly installed at one end of the connecting pipe 602.

[0031] In this embodiment, the controller is used to control the high-pressure blower 6 to start, so that it conveys hot air into the connecting pipe 602, and the hot air is blown out through the air outlet pipes 603 onto the surface of the toughened glass 307 to dry the water stains on the surface of the toughened glass 307. At the same time, the collecting frame 506 and the scraping plate 507 are in a state of rotating in a certain arc. The scraping plate 507 can scrape off the water droplets on the surface of the toughened glass 307, and the air outlet pipes 603 will blow hot air on the surface of the toughened glass 307. In this way, after the toughened glass 307 is cleaned, it can keep the toughened glass 307 in a dry state, thereby reducing the amount of pulverized coal adsorbed on the toughened glass 307.

[0032] Working principle: During use, the coal conveyor belt 1 is used to convey the coal material, causing the coal material to fall into the inside of the coal dropping pipe 2. The camera device 306 monitors the blockage condition of the coal material inside the coal dropping pipe 2. When there is a large amount of coal powder adsorbed on the surface of the toughened glass 307, which affects the monitoring of the blockage condition of the coal material inside the coal dropping pipe 2 by the camera device 306, the controller is used to control the motor 501 to start, so that its output shaft drives the rotating rod 502 to rotate, synchronously driving the gear disk 503 to rotate. Then, under the meshing action of the gear disk 503 and the sector gear 504, the sector gear 504 can be rotated, synchronously driving the connecting bar 505, the collection frame 506 and the scraper 507 to rotate, so that the scraper 507 moves to the position directly below the toughened glass 307. Synchronously, the controller is used to control the electric telescopic rod 303 to start, so that it extends, driving the cover body 304, the camera device 306 and the toughened glass 307 to move downward, making the toughened glass 307 contact with the scraper 507. By controlling the forward and reverse rotation of the motor 501, the scraper 507 can rotate in a certain arc to scrape the coal powder on the surface of the toughened glass 307. Synchronously, the controller is used to control the water pump 401 to start, so that it sucks out the clear water inside the water tank 4, and successively passes through the telescopic hose 402, the U-shaped pipe 403 and the spray pipe 404, and sprays it onto the top of the scraper 507, which can wash the scraper 507 and the toughened glass 307 at the same time, and cooperate with the scraping of the scraper 507 to clean the coal powder on the surface of the toughened glass 307. This can avoid the incomplete cleaning of the coal powder on the surface of the toughened glass 307, thereby improving the cleaning effect of the toughened glass 307, and further ensuring the clarity of the monitoring of the inside of the coal dropping pipe 2 by the camera device 306. When the toughened glass 307 is cleaned, the water pump 401 is turned off, and the controller is used to control the high-pressure blower 6 to start, so that it conveys the hot air into the inside of the connecting pipe 602, and the hot air blows out against the surface of the toughened glass 307 through the air outlet pipe 603 to dry the water stains on the surface of the toughened glass 307. At the same time, the collection frame 506 and the scraper 507 are in a state of rotating in a certain arc. The scraper 507 can scrape off the water droplets on the surface of the toughened glass 307, and the air outlet pipe 603 blows the hot air on the surface of the toughened glass 307. In this way, after the toughened glass 307 is cleaned, the toughened glass 307 can be kept in a dry state, thereby reducing the amount of coal powder adsorbed on the toughened glass 307. When the camera device 306 monitors the inside of the coal dropping pipe 2, the collection frame 506 and the scraper 507, etc. need to be rotated from below the camera device 306 to one side. Then, through the setting of the filter plate 509, it is convenient to filter the sewage. Finally, the valve of the drain pipe 508 can be opened to discharge the filtered water through the drain pipe 508.

[0033] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
