Description

Technical Field

[0001] This utility model relates to the technical field of grinding rollers, and in particular to an oil-leakage-proof grinding roller. Background Technology

[0002] Vertical mills are the main equipment for producing cement clinker. Ensuring the stable operation of vertical mills is of great significance to cement production lines. Grinding rollers are key components of vertical mills, and the bearings of grinding rollers need to be lubricated to ensure smooth production.

[0003] Existing grinding rollers, such as the cement vertical mill grinding roller oil leakage prevention control device disclosed in utility model patent application number 202321543848.X, mainly include an oil inlet of the lubricating oil placement chamber connected to the oil tank through an oil inlet pump and pipeline, an oil return port of the lubricating oil placement chamber connected to the oil tank through a return oil pump and pipeline, and a lubricating oil placement chamber connected to the breather through an air inlet pipe. In use, when the lubricating oil in the lubricating oil placement chamber is at a high level, the lubricating oil enters the oil tank through the oil recovery pipe and will not overflow from the breather. The lubricating oil is automatically circulated through a level gauge, an electric valve, and an oil recovery pump. When the level gauge detects that the lubricating oil is at a high level, the electric valve is automatically opened and the oil recovery pump starts working.

[0004] However, existing lubrication systems use centralized lubrication stations with long pipelines. In winter, when the temperature is low, the viscosity of the lubricating oil increases, its fluidity decreases, and the return of oil is not smooth, resulting in lubricating oil leakage. The leaked lubricating oil not only wastes resources and pollutes the environment, but also poses a hidden danger to the normal operation of the equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an oil-proof grinding roller that can recover lubricating oil overflowing during low-temperature operation through a return oil bypass and a temperature control valve, thereby reducing the use of lubricating oil, reducing maintenance costs, reducing environmental pollution, and increasing equipment operating rate.

[0006] This utility model discloses an oil-leakage-proof grinding roller, including an oil supply mechanism, an oil return mechanism, and a recovery mechanism. The oil return mechanism is installed on the oil supply mechanism to facilitate the return of lubricating oil, and the recovery mechanism is installed on the oil return mechanism to prevent lubricating oil from overflowing. The oil supply mechanism delivers lubricating oil into the grinding roller, and after lubrication, it flows back to the oil tank through the oil return mechanism. When the return oil temperature is too low, the recovery mechanism automatically recovers the overflowing lubricating oil and returns it to the oil tank, reducing maintenance costs, reducing environmental pollution, and increasing equipment operating rate.

[0007] Preferably, the oil supply mechanism includes an oil tank, an oil supply pipeline, a grinding roller, and a lubricating oil chamber. The oil tank is installed on the working surface, and the oil supply pipeline is connected to the inside of the oil tank. The grinding roller is installed on the working surface, and a lubricating oil chamber is provided inside the grinding roller and is connected to the inside of the oil supply pipeline. The lubricating oil in the oil tank is transported to the lubricating oil chamber through the oil supply pipeline, and the lubricating oil lubricates the grinding roller.

[0008] Preferably, the oil return mechanism includes a return pipeline and an exhaust valve. The return pipeline is installed on the lubricating oil chamber and communicates with the inside of the grinding roller. The exhaust valve is installed on the return pipeline. The lubricating oil in the lubricating oil chamber returns to the oil tank through the return pipeline. The exhaust valve facilitates ventilation.

[0009] Preferably, the recovery mechanism includes a reflux bypass and a temperature controller. The reflux bypass is connected and installed between the exhaust valve and the oil tank, and the temperature controller is installed at the front end of the reflux bypass. When the return oil temperature is too low, the temperature controller is turned on to automatically recover the overflowed lubricating oil to the oil tank. After the wear condition is normal and the lubrication system oil temperature is normal, the temperature controller is turned off.

[0010] Preferably, it also includes adding insulation facilities on the return bypass; the insulation facilities increase the fluidity of the lubricating oil in winter.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the oil supply mechanism delivers lubricating oil to the grinding roller, and after lubrication, it flows back to the oil tank through the oil return mechanism. When the return oil temperature is too low, the recovery mechanism automatically recovers the overflowing lubricating oil and returns it to the oil tank, thereby reducing maintenance costs, reducing environmental pollution, and increasing equipment operating rate.

After the grinding condition is normal and the lubrication system oil temperature is normal, the temperature controller 32 is closed. The heat preservation facility increases the fluidity of the lubricating oil in winter.
