Description

Technical Field

[0001] The present application belongs to the technical field of lubrication devices, and in particular relates to a lubrication device and a ring cooler. Background Art

[0002] The ring cooler is a device used for blast cooling of materials in the sintering and pelletizing production processes. A track is installed at the bottom of the rotating body of the rotary frame type ring cooler. The track is in contact with many support wheels fixed on the frame. The rotating body completes the circular rotation motion through the rolling friction between the track and the support wheels. The support wheels bear the weight of the rotating body of the ring cooler and the weight of the materials. The load on a single support wheel is very large. In the actual operation process, due to the thermal deformation of the rotating frame and the installation error of the support wheel, the rolling friction between the track fixed on the rotating body and the surface of the support wheel, which should be in the tangential direction, is changed to the axial sliding friction of the support wheel, resulting in damage to the support wheel bearings, wheel surface and track.

[0003] At present, in order to reduce this sliding friction, some companies manually apply grease to the surface of the support wheel for lubrication, or use immersion oil lubrication for the support wheel; manual grease application is difficult to continuously replenish, which affects the lubrication effect, and further causes damage to the contact surface between the support wheel and the rail, affecting the service life of the device; immersion oil lubrication easily causes some oil products to adhere to the rail and evaporate or drip, which cannot meet the requirements of current environmental protection policies.

[0036] See also Figure 1 as well as Figure 2, the lubrication device provided in the embodiment of the present application includes a fixing seat 100, a housing 200 and a pushing portion 300;

[0037] The fixing seat 100 is connected to the supporting wheel 400 to provide a supporting foundation for the housing 200. In some embodiments, the fixing seat 100 is detachably connected to the supporting wheel 400, and the fixing seat 100 is bolted to the supporting wheel 400; in some embodiments, the supporting wheel 400 includes a hinged wheel body 410 and a supporting seat 420, and the fixing seat 100 is detachably connected to the supporting seat 420, and a fixing hole is provided on the fixing seat 100 to install the housing 200; in some embodiments, the fixing seat 100 is in a "z" shape;

[0038] The housing 200 is connected to the fixing seat 100. The housing 200 is provided with a receiving cavity for receiving the lubricating block 210. The receiving cavity is communicated with the outside of the housing 200. In some embodiments, the housing 200 is cylindrical and has an opening at one end for installing the lubricating block 210. In some embodiments, the housing 200 is connected to the fixing seat 100, and the opening faces the peripheral surface of the supporting wheel 400. In some embodiments, the lubricating block 210 is a graphite block.

[0039] The pushing part 300 is partially located in the accommodating cavity. The pushing part 300 can reciprocate along the radial direction of the supporting wheel 400.

Due to the spring 323, the lubricating block 210 can be continuously in contact with the circumference of the support wheel 400 to a certain extent, thereby ensuring its lubrication effect. In some embodiments, the spring 323 extends along the axial direction of the shell 200.

[0043] In some embodiments, a plurality of springs 323 are provided, which are spaced apart along the circumference of the support plate 321 or the connecting plate 322 to further enhance the force of the support plate 321 on the lubricating block 210; in some embodiments, there are two, three, or four springs 323. In some embodiments, the connecting plate 322 is provided with an installation groove for installing the spring 323, so that the spring 323 can be stably installed.

In some embodiments, the shell 200 is cylindrical, one end is connected to the outside, and the other end is provided with a connecting part for threaded connection of the pushing rod 310, and a vent hole is provided on the side close to the connecting part.

[0048] In some embodiments, a plurality of ventilation holes are provided and spaced apart along the circumference of the shell 200 to further improve the ventilation effect. In some embodiments, two, six, or eight ventilation holes are provided.

[0049] A second embodiment of the present application provides a ring cooler to provide a stable lubrication effect for its supporting wheel 400.

[0050] See also Figure 3The ring cooler provided in the embodiment of the present application includes a main body and a lubricating device, and the lubricating device is detachably connected to the main body. In some embodiments, the lubricating device is detachably connected to the support wheel 400 of the main body, and the support wheel 400 includes a wheel body 410 and a support seat 420 connected to each other. The lubricating device is detachably connected to the support seat 420, and the shell 200 is located on the side of the support wheel 400.

[0051] The following is a detailed description of the use of the lubrication device of the present application:

[0052] See also Figure 3 The fixing seat 100 is fixed to the side of the supporting seat 420 of the supporting wheel 400, so that the opening of the housing 200 faces the supporting wheel 400, and the pushing rod 310 is rotated to move the pushing rod 310 along the axial direction of the housing 200 to push the lubricating block 210 in the housing 200 toward the supporting wheel 400. When the lubricating block 210 abuts against the peripheral surface of the supporting wheel 400, the pushing is stopped. When the supporting wheel 400 rotates, the lubricating block 210 can continuously act on the peripheral surface of the supporting wheel 400 to lubricate the supporting wheel 400. The spring 323 acts on the lubricating block 210 through the support plate 321, so that the lubricating block 210 is tightly attached to the circumference of the support wheel 400 to a certain extent. When the lubricating block 210 is consumed to a certain extent and a gap is generated between the lubricating block 210 and the circumference of the support wheel 400, the push rod 310 is rotated to push the seat 320 close to the support wheel 400 to push the lubricating block 210 so that the lubricating block 210 continues to act on the support wheel 400. When the lubricating block 210 is completely consumed, the push rod 310 is rotated in the opposite direction to install the lubricating block 210.
