Description

Technical Field

[0001] This utility model relates to the technical field of boiler furnace flame monitoring devices, specifically a boiler furnace flame monitoring device. Background Technology

[0002] A boiler is a device that uses various fuels, electricity, or other energy sources to heat a contained liquid to certain parameters and provides heat energy through the output of a medium. Its scope typically includes pressurized steam boilers with a normal design water volume greater than or equal to 30L and a rated steam pressure greater than or equal to 0.1MPa (gauge pressure); pressurized hot water boilers with an outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and a rated power greater than or equal to 0.1MW; and organic heat carrier boilers with a rated power greater than or equal to 0.1MW. To facilitate monitoring of the boiler flame, observation devices are usually installed on the boiler for easy flame observation.

[0003] For example, the observation device for boiler flame monitoring proposed in Chinese patent CN220229261U uses an elastic scraper assembly to ensure that the scraper is always in close contact with the glass plate by setting up a cleaning mechanism, thus ensuring the cleaning effect.

[0004] Although the above solution uses scrapers and other structures to clean the observation window, the boiler produces a large amount of flue gas during operation. When the flue gas is cleaned by the scraper, it adheres to the outside of the scraper, which affects the subsequent cleaning of the scraper and thus affects the flame monitoring operation of the boiler.

[0031] The guide block 71 can rotate with the first gear 5, the slide plate 72 can slide linearly inside the guide block 71, and the slide plate 72 can scrape the outside of the monitoring window 2. The guide block 74 can guide the slide plate 72 to move linearly, and the connecting rod 76 can drive the L-shaped scraper 77 to move up and down. The L-shaped scraper 77 can clean the slide plate 72.

[0032] Please see Figure 3 and Figure 4 The bottom of the motor 3 is equipped with a base 31, and the base 31 is connected to the observation window 1. The base 31 can support and fix the motor 3. The motor 3 has a seated spherical bearing 73 inserted inside, and the seated spherical bearing 73 is connected to the guide groove block 71. The seated spherical bearing 73 can support the guide groove block 71 and improve the stability of the guide groove block 71 during movement.

[0033] The guide block 71 has slots 79 on both sides inside. The slots 79 are slidably connected to the connecting rod 76. The slots 79 facilitate the transmission of the connecting rod 76. A telescopic rod 78 is connected between the L-shaped scraper 77 and the guide block 71. The telescopic rod 78 includes a sleeve and a sliding rod. The sliding rod is slidably connected to the sleeve. The sliding rod and the sleeve are respectively connected to the guide block 71 and the L-shaped scraper 77. The telescopic rod 78 can guide the L-shaped scraper 77 to make it perform linear reciprocating motion.

[0034] The end of the slide plate 72 near the cylinder 4 has a rounded corner design, and the slide plate 72 is slidably connected to the cylinder 4.

When the monitoring window 2 needs to be cleaned, the motor 3 is started to drive the second gear 6 to rotate, which in turn drives the first gear 5 to rotate, and then drives the cleaning mechanism 7 to scrape the monitoring window 2, thus completing the cleaning of the monitoring window 2. At the same time, when the guide block 71 and the slide plate 72 rotate, the slide plate 72 will collide with the cylinder 4 and then retract into the inside of the guide block 71. Then, it will be returned to its original position by the spring 75. This reciprocating motion realizes the self-cleaning of the slide plate 72, preventing dust from adhering to the outside of the slide plate 72. At the same time, when the slide plate 72 moves, it drives the connecting rod 76 to drive the L-shaped scraper 77 to move up and down, scraping the outside of the slide plate 72, preventing dust from adhering to the outside of the slide plate 72 and being shaken off properly.

[0037] The furnace flame of the boiler is monitored through monitoring window 2.

At the same time, the cleaning mechanism 7 works with the added cylinder 4 to shake the plate 72 to prevent dust from adhering to the outside of the plate 72 and affecting its normal cleaning effect. At the same time, the added connecting rod 76 and L-shaped scraper 77 can clean the plate 72 again when the plate 72 is shaken, to prevent dust from solidifying on the outside of the plate 72 and not being able to be shaken off properly, thus affecting the normal operation of the plate 72.
