Description

A new type of oil mist purification and recovery device in the fuel tank

technical field

The utility model belongs to the technical field of lubrication and relates to a novel oil mist purification and recovery device in an oil tank.

Background technique

Whether it is in the process of CNC machine tool processing or in the process of high-pressure rapid oil supply and oil return in oil stations in the hydraulic lubrication industry, a large amount of oil mist is often generated, which implicitly and seriously damages the physical and mental health of the staff, and the oil mist Permeating the site is disgusting and irritating, affecting production efficiency; secondly, if the oil mist is allowed to spread in the workshop for a long time, it will also cause damage to the components in the lubrication system and cause losses.

Therefore, as people pay more and more attention to environmental protection today, it is an urgent problem for many lubricating equipment manufacturers to choose a clean air environment that can eliminate oil mist and recycle expensive lubricating oil.

Some imported oil mist collection devices used in oil stations are very expensive, and the follow-up maintenance costs are high, making it unaffordable for domestic manufacturers. At the same time, at present, most of the oil mist collection devices at home and abroad use multi-layer fine filter materials, trying to achieve the filtering effect with a large number of barriers. This type of oil mist collection device has a short service life, is easy to block, and has a large pressure loss. The fuselage is easy to vibrate during use and requires frequent maintenance and cleaning.

At present, manufacturers in the domestic lubrication industry install small blower equipment on the oil tank of the oil station to replace the oil mist purifier device to remove the dirty oil mist generated inside the oil tank. The blower is mainly composed of a motor, an impeller and a baffle, which are almost completely enclosed in a metal shell. Since the shell needs to consider the position of the baffle, the setting of the fixed position of the motor, etc., the airflow channel formed by the rotating impeller and the shell is restricted. , resulting in low exhaust efficiency and weak pumping rate; at the same time, the maintenance of this type of oil mist collector is also inconvenient, and most of them need to be disassembled to varying degrees, which is very cumbersome.

In addition, the suction port of the blower is connected to the fuel tank, and the oil mist inside the fuel tank is not filtered, and is directly discharged into the air through the bore pipe of the blower, which can easily cause air pollution and seriously damage the physical and mental health of on-site workers. A large amount of oil and gas spread in the air for a long time will eventually cause damage to the components in the lubrication system and cause losses. Secondly, it is not conducive to the separation of oil and gas, so that oil droplets can be recycled and reused.

Example

During the continuous oil supply and oil return process of the lubricating oil station, when the oil flows and splashes, a large amount of oil mist is often generated in the oil tank. If the oil mist is not cleared, not only will the working performance of the lubrication system be unstable, but the The water vapor in the oil will cause damage to the components of the lubrication system and cause losses, and the oil mist inside the oil tank will penetrate into the outside air through the gap, which will cause air pollution and environmental pollution. However, the blower currently used cannot completely separate the oil and gas in the oil mist. It only extracts the oil mist inside the oil tank to the outside, which also causes air pollution. A large amount of oil mist diffuses in the workshop, and the water vapor in the oil mist This in turn leads to damage to the components of the lubrication system, which affects the performance of the lubrication system.
