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

Abstract

The invention relates to a hydraulic oil tank respirator which comprises a lower respiration base, a shell and a lower cover, wherein the lower respiration base is used for connecting an oil tank; the shell is arranged on the lower respiration base; the lower cover is arranged on the shell; an air vent is formed in the lower respiration base; a threaded hole is formed in the lower cover; the hydraulic oil tank respirator further comprises a spiral separating part arranged between the shell and the lower cover; the spiral separating part comprises a separating drum, a spiral blade, a blade shaft and a separating baffle; the outer edge of the spiral blade is fixed on the inner wall of the separating drum; the inner edge of the spiral blade is fixed on the blade shaft; the lower end of the blade shaft is aligned with the lower end of the separating drum; the upper end extends out of the separating drum and is connected with the separating baffle. The hydraulic oil tank respirator aims to reduce the concentration of oil particles arriving at an upper expiration device by an oil filter screen and the spiral separating part arranged in the lower respiration base, so that the cotton web filter element in the upper expiration device can fully absorb the oil particles and the oil particles can be prevented from flowing out of the vent hole, polluting environment and influencing the appearance of the hydraulic oil tank.

Description

technical field [0001] The invention belongs to the technical field of oil tanks and relates to 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 breathing port, so that Hydraulic oi...
