Description

Oil leakage prevention grinding roller Technical Field The utility model relates to the technical field of grinding rolls, in particular to an oil leakage prevention grinding roll. Background The vertical mill is a main device for producing cement clinker, ensures that the stable operation of the vertical mill has important significance for cement production lines, and the grinding roller is a key component of the vertical mill, so that the grinding roller bearing is required to be lubricated in order to ensure smooth production. When the oil in the oil placing cavity is at a high liquid level, the oil enters the oil tank through the oil recovery pipeline, the oil cannot overflow from the breather, the automatic circulation of the oil is realized through the liquid level meter, the electric valve and the oil recovery pump, and when the liquid level meter monitors that the oil is at the high liquid level, the electric valve is automatically started to be opened and the oil recovery pump starts to work. However, the existing lubrication system adopts centralized lubrication of oil stations, the pipeline is longer, the viscosity of the lubricating oil is high and high in the low-temperature operation in winter, the fluidity is reduced, the oil return is not smooth, the lubricating oil is leaked, the leaked lubricating oil not only wastes resources, but also pollutes the environment, and meanwhile, hidden danger is brought to the normal operation of equipment. Disclosure of utility model In order to solve the technical problems, the utility model provides the oil leakage prevention grinding roller which can recycle the lubricating oil overflowed during low-temperature operation through the oil return bypass and the temperature control valve, reduce the use of the lubricating oil, further reduce the maintenance cost, reduce the environmental pollution and increase the equipment operation rate. The oil leakage preventing grinding roller comprises an oil supply mechanism, an oil return mechanism and a recovery mechanism, wherein the oil return mechanism is arranged on the oil supply mechanism and is convenient for lubricating oil to flow back, the recovery mechanism is arranged on the oil return mechanism and is used for avoiding lubricating oil from overflowing, the oil supply mechanism conveys lubricating oil into the grinding roller, the lubricating oil flows back into an oil tank through the oil return mechanism after lubrication is finished, and when the oil return temperature is too low, the recovery mechanism automatically recovers the overflowing lubricating oil and flows back into the oil tank, so that maintenance cost is reduced, environmental pollution is reduced, and equipment operation rate is increased. Preferably, the oil supply mechanism comprises an oil tank, an oil supply pipeline, a grinding roller and a lubricating oil cavity, wherein the oil tank is arranged on the working surface, the oil supply pipeline is communicated with the interior of the oil tank, the grinding roller is arranged on the working surface, the lubricating oil cavity is arranged in the grinding roller and is communicated with the interior of the oil supply pipeline, lubricating oil in the oil tank is conveyed into the lubricating oil cavity through the oil supply pipeline, and the lubricating oil lubricates the grinding roller. Preferably, the oil return mechanism comprises a return pipeline and an exhaust valve, the return pipeline is arranged on the lubricating oil cavity and is communicated with the inside of the grinding roller, the exhaust valve is arranged on the return pipeline, lubricating oil in the lubricating oil cavity flows back into the oil tank through the return pipeline, and ventilation is facilitated by arranging the exhaust valve. Preferably, the recovery mechanism comprises a reflux bypass and a temperature controller, wherein the reflux bypass is arranged between the exhaust valve and the oil tank in a communicating way, the temperature controller is arranged at the front end of the reflux bypass, when the oil return temperature is too low, the temperature controller is opened, the overflowed lubricating oil is automatically recovered to the oil tank, the condition is normal when the oil temperature of the lubricating system is normal, and the temperature controller is closed. Preferably, the device also comprises a heat preservation facility which is additionally arranged on the reflux bypass, and the fluidity of the lubricating oil in winter is increased through the heat preservation facility. Compared with the prior art, the oil supply mechanism has the beneficial effects that the oil supply mechanism conveys lubricating oil into the grinding roller, the lubricating oil flows back into the oil tank through the oil return mechanism after lubrication is finished, when the oil return temperature is too low, the recovery mechanism automatically recovers the overflowed lubricating oil and flows back into
