Description

Technical Field

[0001] This utility model relates to the field of hot blast stove track cleaning technology, and in particular to a hot blast stove sliding track foreign object cleaning device. Background Technology

[0002] In industrial production such as steel and metallurgy, hot blast stoves are key equipment for providing high-temperature hot air, and their operational stability directly affects smelting efficiency and product quality. The stove body or related components often need to be moved or raised along sliding tracks to achieve functions such as hot air delivery and maintenance. Therefore, the cleanliness of the sliding tracks is a core prerequisite for ensuring smooth equipment operation. However, the operating environment of hot blast stoves is harsh, and the sliding tracks easily accumulate various foreign objects, mainly including: first, solid impurities such as iron filings, slag, and dust generated during production, which fall into the track gaps as the equipment operates; second, condensed metal oxides that volatilize under high temperatures, adhering to the track surface to form hard scale; and third, tool debris, insulation material fragments, etc., left over from maintenance. If these foreign objects are not cleaned in time, they will cause a series of problems.

[0003] Foreign objects can exacerbate friction and wear between the track and sliding components, causing scratches and deformation on the track surface, and even jamming of the sliding components, increasing the resistance of equipment operation. In severe cases, it may cause mechanical failure, forcing the production line to stop for maintenance and causing huge economic losses. When using existing cleaning devices, workers need to fix them to one side of the slider and adjust the cleaning device to make it abut against the track. The adjustment is time-consuming and laborious, and the position needs to be locked with bolts after the adjustment, making it inconvenient to remove the cleaning device later. Therefore, we have proposed a foreign object cleaning device for the sliding track of a hot blast stove. Utility Model Content

[0032] In this embodiment, the track cleaning guide assembly 1 also includes a motor 18, a worm gear 19, and a worm wheel 20. The motor 18 is fixedly installed inside the control box 6, the worm gear 19 is fixedly installed at the output end of the motor 18, and the worm wheel 20 is fixedly installed outside the first rotating shaft 11. The worm gear 19 and the worm wheel 20 mesh with each other. The motor 18 drives the worm gear 19 to mesh with the worm wheel 20, thereby driving the first rotating shaft 11 and the turntable 12 to rotate. The connecting rocker arm 13 then pushes the guide slider 14 to slide along the guide groove, so that the wire brush 16 and the wiping roller 17 on the outside of the second rotating shaft 15 automatically approach or move away from the track body 3. There is no need for manual adjustment and bolt locking, which solves the problem of time-consuming and laborious adjustment of traditional devices and greatly improves the operating efficiency.

The rotating limiting scraper 24 is fixedly installed on the outside of the movable shaft 22 and the auxiliary shaft 23. The rotating limiting scraper 24 works in coordination with the limiting guide scraper 21, which makes the rotating limiting scraper 24 and the limiting guide scraper 21 relatively stable during movement and prevents them from shaking. It also prevents the cleaning device from detaching from the inside of the track body 3. After the rotating limiting scraper 24 rotates, it can fit against the inner wall of the track body 3, resulting in a better cleaning effect. After cleaning, rotating it in the opposite direction makes it easy to remove.

[0034] In this embodiment, the track cleaning and dust collection assembly 2 further includes a transmission gear 25, a synchronous pulley 26, and a synchronous belt 27.

[0036] In this embodiment, the control box 6 is provided with multiple guide grooves, and the guide slider 14 is slidably installed on the inner side of the guide grooves; the guide grooves allow the guide slider 14 to slide only after being subjected to force, preventing it from deviating or other situations.

[0037] In this embodiment, the wire brush 16 and the wiping roller 17 are fixedly installed on the outside of the second rotating shaft 15 by connecting flange and bolts; the wire brush 16 and the wiping roller 17 are detachably installed on the outside of the second rotating shaft 15 by connecting flange and bolts, which facilitates quick replacement after wear; the movable slider 4 is connected to the control box 6 by connecting flange 8, and can be separated by loosening the bolts, which solves the problem of inconvenience in removing the traditional device later, and reduces maintenance time and cost.

[0038] Specifically, the track cleaning guide assembly 1 is driven by a motor 18 to engage a worm gear 19 with a worm wheel 20, which in turn drives the first rotating shaft 11 and the turntable 12 to rotate. The connecting rocker arm 13 then pushes the guide slider 14 to slide along the guide groove, causing the wire brush 16 and wiping roller 17 on the outside of the second rotating shaft 15 to automatically move closer to or away from the track body 3. This eliminates the need for manual adjustment and bolt locking, solving the problem of time-consuming and labor-intensive adjustment in traditional devices and significantly improving operational efficiency. The wire brush 16 and wiping roller 17 are detachably installed on the outside of the second rotating shaft 15 via connecting flanges and bolts, facilitating quick replacement after wear. The movable slider 4 is connected to the control box 6 via connecting flange 8, and can be separated by loosening the bolts, solving the problem of inconvenient removal in traditional devices and reducing maintenance time and costs.

[0039] The wire brush 16 can remove hard scale and iron filings from the surface of the track body 3, and the wiping roller 17 further wipes away residual dust. In conjunction with the limiting guide scraper 21 and the rotating limiting scraper 24 of the track cleaning vacuum assembly 2, it can scrape away foreign objects in the track gaps. The vacuum pump 28 sucks the dust generated during cleaning into the vacuum box 9 through the vacuum tube 29, and the collection drawer 30 centrally processes it to avoid secondary pollution, reduce foreign objects in the track in all directions, and reduce the risk of friction and wear.

[0040] The guide pulley 5 on the inner side of the movable slider 4 abuts against the track body 3, ensuring that the device slides smoothly along the track. The cooperation of the synchronous wheel 26 with the synchronous belt 27 and the transmission gear 25 enables the rotating limit scraper 24 and the limit guide scraper 21 to work together, which makes the rotating limit scraper 24 and the limit guide scraper 21 relatively stable during movement, without shaking, and prevents the cleaning device from detaching from the inside of the track body 3. After the rotating limit scraper 24 rotates, it can fit against the inner wall of the track body 3, resulting in a better cleaning effect. After cleaning, rotating it in the opposite direction makes it easy to remove, avoiding track scratches caused by component shaking during cleaning, ensuring smooth operation of the hot air furnace sliding components, and reducing mechanical failures and downtime losses.
