Description
Technical Field
The utility model relates to the technical field of hydraulic filtration of wind power generation gear boxes, in particular to an air filtering device for a wind power generation gear box.
Background
The air filter installed on the wind power gear box mainly has two functions. Firstly, particle impurities and moisture in air entering a box body are filtered, the particles and the moisture are prevented from entering the interior of a gear box to cause failure of the gear box, and the service life of the gear box is prolonged; secondly, under the condition of continuous operation of the wind power gear box, the temperature can become very high, so that the gas inside the gear box expands and the pressure rises, the atmospheric pressure inside and outside the gear box is balanced by ventilation of the air filter, and meanwhile, the oil mist in the gear box is captured to avoid entering the engine room.
An existing wind power gear box air filter is directly installed on a box body as shown in figure 3, and when the gear box runs for a period of time, an oil leakage phenomenon exists at the air filter. Reasons for oil bleeding include: on one hand, the rotating gear in the gearbox body drives the lubricating oil to splash to the air outlet of the air filter at a high speed and then seep out; on the other hand, lubricating oil forms certain oil mist at high temperature, enters the air filter along with hot air flow, and seeps out after being cooled.
At present, to solve the oil leakage phenomenon, there are two measures generally adopted: (1) the height of the air filter is increased, the height of an installation lug of the air filter in a box body is increased, or a transition sleeve is added between an installation hole of the box body of the gear box and the air filter; (2) an oil baffle plate or a purification cylinder and the like are additionally arranged below the gearbox body at the mounting hole of the air filter. With the first measure, increasing the height of the air cleaner brings new problems in terms of installation and lifting. For the second measure, the oil baffle plate has the main function of blocking lubricating oil which is driven by a gear rotating in the box body and splashes to the air outlet of the air filter at a high speed, and has little effect on separating oil mist in air in the box. The purification cylinder can prevent lubricating oil splashed at a high speed from entering the air filter, and has a certain separation effect on oil mist in hot air flow, but is not high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an air filtering device for a wind power gear box, which is used for solving at least one technical problem, can prevent lubricating oil splashed at a high speed from entering an air filter, has a high separation effect on oil mist in hot air flow, does not influence the installation and hoisting of the gear box, and effectively solves the problem of oil leakage at the air filter.
The embodiment of the utility model is realized by the following steps:

Due to the action of centrifugal force, most oil mist in the air flow is thrown onto the outer inner wall of the cyclone, and a small part of oil mist enters the inner cavity of the central guide cylinder along with the air flow through gaps of the central guide cylinder and an air vent of the air filter. Because of the change of the airflow direction, large airflow disturbance is caused, oil mist in the airflow collides against the wall surface, is cooled and condensed into liquid and slides to the bottom of the cylinder.
In a preferred embodiment of the utility model, the diameter of the central guide cylinder of the air filtering device for the wind power gear box is larger than that of the air vent.
In a preferred embodiment of the utility model, the flange ring of the air filtering device for the wind power gear box is mounted at the mounting opening of the wind power gear box through bolts.

The technical effects are as follows: the diameter and the quantity of the oil outlet holes in the bottom of the central guide cylinder are arranged, so that lubricating oil can fully flow back into the box body of the wind power gear box, and meanwhile, the lubricating oil splashed in the box body is prevented from entering the inside of the central guide cylinder. The oil mist penetrates through the oil outlet and falls into the wind power gear box.
The embodiment of the utility model has the beneficial effects that:
the utility model can prevent the lubricating oil splashed at high speed from entering the air filter, simultaneously has higher separation efficiency on oil mist in the air in the wind power gear box, enables less oil mist to enter the air filter, reduces the risk of oil leakage at the air filter and prolongs the service life of the air filter.
