Description
Technical Field
The invention relates to the technical field of vertical mills, in particular to an oil return flow guide device for a grinding roller of a vertical mill.
Background
The vertical mill is a main grinding device and is widely applied to occasions of grinding raw materials, cement, coal dust, slag, steel slag and the like. The grinding roller is one of the core components of the vertical mill, and the quality of the sealing performance of the grinding roller is an important index for evaluating the performance of the vertical mill. At present, most of vertical grinding roller lubrication oil return all adopt to add a section honeycomb duct at the roller axle tip and control the interior oil level of grinding roller, and this kind of form has increased the pipeline and has installed more complicacy, if the installation is insecure, the condition that takes place to drop easily, easily causes more serious accident.
Disclosure of Invention
The invention aims to solve the technical problem of providing the oil return flow guide device of the grinding roller of the vertical mill, which has the advantages of simple structure, easy adjustment and good oil return effect by changing the internal structure of the pressure plate.
In order to solve the technical problem, the invention is realized as follows: designing an oil return flow guide device of a grinding roller of a vertical mill, which consists of a pressure plate, a connecting bolt, a double-lug stop gasket and an adjusting bolt; the pressing plate is circular, and the diameter of the pressing plate is larger than that of the grinding roller shaft; the pressing plate is fixedly connected with the end surface of the grinding roller shaft through a connecting bolt and a double-lug stop gasket; the edge of the pressure plate is tightly attached to a grinding roller bearing arranged on a grinding roller shaft and forms sealing connection; the inner side of the pressure plate is provided with a diversion trench communicated with the oil return channel of the grinding roller shaft.
Furthermore, a plurality of oil return ports are formed in the inner wall of the guide groove on the pressing plate, and adjusting bolts are installed on the oil return ports.
The invention has the following positive effects: in the technical scheme, the oil return flow guide device of the vertical grinding roller is simple in structure, easy to adjust and good in oil return effect by changing the internal structure of the pressing plate, is applied to engineering projects and achieves a good effect.

In the figure, 1, a platen; 2. a connecting bolt; 3. a binaural stopper pad; 4. adjusting the bolt; 5. an oil return port; 6. a diversion trench; 7. a roll axis of the mill; 8. an oil line; 9. grinding roller bearing.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the following detailed description and the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
As shown in fig. 1, the oil return guiding device of the grinding roller of the vertical grinding mill comprises a pressure plate 1, a connecting bolt 2, a double-lug stop gasket 3 and an adjusting bolt 4; the pressing plate 1 is circular, and the diameter of the pressing plate is larger than that of the grinding roll shaft 7; the pressing plate 1 is fixedly connected with the end surface of the grinding roll shaft 7 through a connecting bolt 2 and a double-lug stop gasket 3; the edge of the pressure plate 1 is tightly attached to a grinding roller bearing 9 arranged on the grinding roller shaft 7 and is in sealing connection; the inner side of the pressure plate 1 is provided with a diversion trench 6 communicated with an oil return channel of the grinding roller shaft 7.
Furthermore, a plurality of oil return openings 5 are formed in the inner wall of the guide groove 6 on the pressing plate 1, and adjusting bolts 4 are installed on the oil return openings 5. When the oil level adjusting device is used, the corresponding adjusting bolt is removed to achieve the purpose of adjustment only by selecting the required oil level (see the oil level line 8 in the drawing).
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention, and various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention shall fall within the protection scope of the present invention, and the technical contents of the present invention which are claimed are all described in the claims.
