Description

Technical Field

[0001] This invention relates to the field of guide wheel bearing arrangement in slag removal machines, and in particular to a guide wheel bearing protection device. Background Technology

[0002] During the operation of traditional slag removers, the guide wheel bearings are in a harsh working environment for a long time. They are immersed in slag water containing ash and slag. Although air-sealed oil seals are used, the sealing lips are prone to wear due to the corrosiveness of the slag water and the impact of ash and slag particles. This leads to the slag water penetrating into the bearing, aggravating bearing wear, reducing bearing service life, and seriously affecting the normal operation and production efficiency of the slag remover.

[0003] Furthermore, when the bearing needs maintenance or replacement, the entire guide wheel assembly must be disassembled, which is extremely complicated and time-consuming, causing the slag remover to malfunction. The long downtime brings great inconvenience and losses to production. Therefore, in order to maximize the protection of the bearing, extend its service life, and reduce the complexity of disassembling and replacing the bearing, we propose a guide wheel bearing protection device. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is that the bearing of the guide wheel is in a slag water environment for a long time, which is easily corroded, and the entire guide wheel component needs to be disassembled when replacing the bearing, which is very troublesome.

[0005] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes a guide wheel bearing protection device, which includes a guide wheel disposed on the inner side of the machine plate of the slag remover; and a bearing disposed on the outer side of the machine plate of the slag remover; and the guide wheel and the bearing are connected by a rotating shaft, and the bearing is disposed in a bearing housing, and the bearing housing and the machine plate are sealed.

[0006] In a preferred embodiment of the guide wheel bearing protection device of the present invention: a sealing structure is provided on the inner side of the bearing housing, the sealing structure including a stationary ring and a rotating ring, the stationary ring being fixedly connected to the machine plate by bolts through a flange.

[0007] In a preferred embodiment of the guide wheel bearing protection device of the present invention: the moving ring is disposed on the side of the stationary ring close to the bearing, an elastic element is sleeved on the outside of the moving ring, and an extension ring is provided at one end of the moving ring.

[0008] In a preferred embodiment of the guide wheel bearing protection device of the present invention: the inner wall of the bearing housing is provided with a movable groove, and the extension ring is movably engaged with the movable groove.

[0009] In a preferred embodiment of the guide wheel bearing protection device of the present invention: a sealing ring is provided inside the movable groove, and the sealing ring is movably engaged with the extension ring.

[0010] In a preferred embodiment of the guide wheel bearing protection device of the present invention: an air injection hole is provided through the outer wall of the movable groove, the air injection hole is connected to an air source, and by injecting gas into the air injection hole, the gas enters the movable groove and cooperates with the sealing ring.

[0011] In a preferred embodiment of the guide wheel bearing protection device of the present invention: the rotating shaft is split into two sections, and the two sections are connected by a coupling. One end of one section is connected to the guide wheel, and the other end of the other section is connected to the bearing.

[0012] In a preferred embodiment of the guide wheel bearing protection device of the present invention: an oil injection nozzle is provided above the bearing housing, and the oil injection nozzle is connected to an automatic lubrication pump.

[0013] In a preferred embodiment of the guide wheel bearing protection device of the present invention: a drain outlet is provided below the bearing housing, and a humidity sensor and a drain valve are provided at the drain outlet.

[0015] The beneficial effects of this invention are as follows: by using an external bearing housing to isolate the slag and water, the bearing is prevented from being corroded by the slag and water environment. This design eliminates the need for the complex operation of disassembling the guide wheel when replacing the bearing, thus extending the service life of the bearing. Furthermore, the sealing structure provides secondary protection for the bearing, preventing slag and water from entering the intermediate bearing due to wear and causing damage, thereby maximizing the protection of the bearing.

[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0022] Reference Figure 1 This embodiment provides a guide wheel bearing protection device, including a guide wheel 1, which is disposed on the inner side of the machine plate 2 of the slag remover; and a bearing 3, which is disposed on the outer side of the machine plate 2 of the slag remover; and the guide wheel 1 and the bearing 3 are connected by a rotating shaft 11, and the bearing 3 is disposed in a bearing housing 31, and the bearing housing 31 and the machine plate 2 are sealed.

[0023] The guide wheel 1 of the slag remover is mainly used to provide guidance and support for the conveying components such as chains or scrapers, ensuring that the conveying components can operate smoothly and efficiently, thereby ensuring the normal operation of the slag remover.

[0024] Originally, both the guide wheel 1 and the bearing 3 were located on the inner side of the machine plate 2. However, this arrangement would cause the bearing 3 to be immersed in the slag water environment for a long time, resulting in corrosion and wear of the bearing 3. Therefore, a split design was adopted, placing the bearing 3 on the outer side of the slag remover machine plate 2 to physically isolate it from the slag water, and then providing secondary sealing protection for the bearing housing 31.

[0025] As an optional embodiment, the bearing housing 31 is provided with a sealing structure 4 on the inner side. The sealing structure 4 includes a stationary ring 41 and a rotating ring 42. The stationary ring 41 is bolted to the machine plate 2 via a flange 21.

[0026] like Figure 3 As shown, the sealing structure 4 adopts a double-layer sealing ring. The stationary ring 41 is welded to the flange face of the machine plate 2, and the dynamic ring is embedded in the bearing housing 31. The sealing gap can be filled with high-temperature resistant fluororubber to enhance the sealing effect.

[0027] As an optional embodiment, the moving ring 42 is disposed on the side of the stationary ring 41 close to the bearing 3, and an elastic element 421 is sleeved on the outside of the moving ring 42. An extension ring 422 is provided at one end of the moving ring 42.

[0028] The elastic element 421 is preferably a compression spring.

[0029] The diameter of the extension ring 422 is larger than that of the moving ring 42, and the extension ring 422 and the moving ring 42 are integrally connected.

[0030] As an optional embodiment, the inner wall of the bearing housing 31 is provided with a movable groove 311, and the extension ring 422 is movably engaged with the movable groove 311.

[0031] The movable groove 311 is set as an annular shape, and the extension ring 422 can slide inside it.

[0032] As an optional embodiment, the movable groove 311 is provided with a sealing ring 3111 inside, and the sealing ring 3111 is movably engaged with the extension ring 422.

[0033] One end of the sealing ring 311 contacts the extension ring 422, and the air injection hole 3112 is located at the other end of the sealing ring 311.

[0034] As an optional embodiment, the outer wall of the movable groove 311 is provided with an air injection hole 3112. The air injection hole 3112 is connected to an air source. By injecting gas into the air injection hole 3112, the gas enters the movable groove 311 and cooperates with the sealing ring 3111.

[0035] Air inlet 3112 connects to a device that can provide an air source, such as a compressed air supply.

[0036] By injecting gas into the air injection hole 3112, the gas enters the movable groove 311 and cooperates with the sealing ring 3111. The sealing ring 3111 then contacts the moving ring 42, thereby providing preload in the direction close to the stationary ring 41, thus strengthening the seal and providing a second layer of protection on top of physically isolating the bearing 3.

[0037] As an optional embodiment, the rotating shaft 11 is split into two sections, which are connected by a coupling 12. One end of one section of the rotating shaft 11 is connected to the guide wheel 1, and the other end of the rotating shaft 11 is connected to the bearing 3.

[0038] With its split design, when the bearing housing 31 needs to be disassembled and replaced, there is no need to pull out the guide wheel 1 before disassembling the bearing 3. This design makes disassembly and replacement more convenient and prevents sludge and water from getting into the bearing.

[0039] As an optional embodiment, an oil injection nozzle 312 is provided above the bearing housing 31, and the oil injection nozzle 312 is connected to an automatic lubrication pump.

[0040] The main function of the grease nipple 312 is to add oil to the bearing 3 and to lubricate the bearing 3 periodically.

[0041] As an optional embodiment, a drain outlet 313 is provided below the bearing housing 31, and a humidity sensor and a drain valve are installed at the drain outlet 313.

[0042] The main function of the drain outlet 313 is to prevent water from entering due to poor sealing. The drain outlet 313 can drain water, and the humidity sensor monitors it, providing an extra layer of protection for the bearing 2 and improving the overall service life.

[0043] A temperature sensor can be installed inside the bearing housing 31 to monitor the temperature and transmit the data to the control center.

[0044] As an optional embodiment, a base 314 is provided at the bottom of the bearing housing 31 to support the bearing housing 31. A dust cover 315 is provided at the top of the bearing housing 31, and the outer wall of the dust cover 315 is fixedly connected to the machine plate 2 of the slag remover. The dust cover 315 covers the interface of the bearing housing 31 from above for protection.

[0045] By placing the bearing housing 31 on the outside of the slag remover plate 2 and the guide wheel 1 on the inside of the slag remover plate 2, the bearing 3 is prevented from directly contacting the slag and water, thus preventing the bearing 3 from being corroded and damaged by being in the slag and water environment for a long time. In addition to physical isolation, a sealing structure 4 is added to improve the protection effect.

[0046] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
