Description

Technical Field

[0001] The utility model relates to the technical field of rolling rollers, in particular to a wear-resistant and corrosion-resistant rolling roller. Background Art

[0002] The rolling roller (oil processing) is a kind of equipment component specially used in the oil processing process. In the oil processing industry, especially in refineries, chemical plants and other related facilities, it is often necessary to roll, mix or process oil products. These processes usually involve high temperature, high pressure and corrosive environment, so extremely high requirements are placed on the equipment components used. At present, the wear resistance and corrosion resistance of the rolling roller are improved on the material, and the rotating parts and the rotating shaft at both ends of the rolling roller will be affected by corrosion, resulting in a greatly reduced life of the rolling roller and reduced transmission efficiency. At the same time, if larger raw materials are encountered during the rolling process, the rotating shaft will be affected and vibrate, which will affect the shaft seat and the power unit and will also generate noise. Therefore, we propose a wear-resistant and corrosion-resistant rolling roller. Utility Model Content

The wear resistance and corrosion resistance of the rolling roller are improved by improving the material. However, the rotating parts at both ends of the rolling roller and the rotating shaft will be affected by corrosion, which will greatly reduce the life of the rolling roller and reduce the transmission efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Furthermore, the shock absorbing structure includes a shock absorber and a bending piece, wherein the bending piece is close to the rotating shaft, and when the rotating shaft vibrates, the rotating shaft contacts the bending piece and transmits the vibration to the shock absorber through the bending piece for absorption and relief.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, through the design of the cover seat, the coupling and the shaft seat are built into the groove body opened at the end of the rolling roller for protection to prevent the connection part from being corroded. At the same time, the design of the sealing gasket makes it more convenient to clean, and the sealing gasket can be replaced, and the corrosion resistance effect is improved.
