Spiral separation device for hydraulic oil tank breather

Abstract

The invention relates to a spiral separation device for a hydraulic oil tank respirator. The spiral separation device comprises a connecting seat used for being connected with an oil tank, a housing arranged on the connecting seat, a cover body arranged on the housing, and a spiral separation part arranged between the housing and the cover body, wherein a vent hole is formed in the connecting seat; a threaded hole is formed in the cover body; the spiral separation part comprises a separation cylinder, a spiral blade, a blade shaft and a baffle; the outer edge of the spiral blade is fixed on the inner wall of the separation cylinder; the inner edge of the spiral blade is fixed on the blade shaft; the lower end of the blade shaft aligns with the lower end of the separation cylinder; and the upper end of the blade shaft extends out of the separation cylinder and is connected with the baffle. The invention aims to achieve the effects that through the arrangement of an oil filter screen and the spiral separation part, oil particles in exhausted air can be effectively adsorbed on the oil filter screen and the spiral separation part, so that the concentration of the oil particles getting to the respirator can be reduced, and the phenomena that the environment is contaminated and the appearance of the hydraulic oil tank is influenced by the oil particles flowing out of an air outlet of the respirator can be avoided.

Description

technical field [0001] The invention belongs to the technical field of oil tanks, and relates to a spiral separation device for a hydraulic oil tank respirator. Background technique [0002] The hydraulic oil tank is an essential oil storage container for hydraulic equipment. When the piston rod of the hydraulic cylinder is stretched out, the hydraulic pump sends the hydraulic oil to the hydraulic cylinder, and when the piston rod of the hydraulic cylinder retracts, the hydraulic oil returns. The hydraulic oil tank, so the hydraulic oil tank needs to be provided with a breathing port to communicate with the outside, so that the air in the tank can flow in and out with the hydraulic oil in and out. After the equipment works for a long time, there are many hydraulic oil particles floating in the air in the hydraulic oil tank. When the hydraulic oil returns to the hydraulic oil tank, the hydraulic oil in the hydraulic oil tank increases, and the air is discharged from the breat...

AI Technical Summary

Problems solved by technology

When the air in the hydraulic oil tank enters and leaves the respirator with this structure, the hydraulic oil particles contained in the air adhere to the filter cotton. When the hydraulic oil adhered to the filter cotton reaches saturation, the hydraulic oil on the filter cotton is exhaled. Under the action of airflow and gravity, it flows out through the air outlet of the respirator to pollute the environment and affect the appearance of the hydraulic oil tank
