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

Embodiment Construction
[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0027] Such as Figure 1-2 As shown, a fuel tank respirator with centrifugal separation includes a respirator and a centrifugal separation device arranged on the respirator, and the respirator includes a breathing seat 8, an upper cover 9 arranged on the breathing seat 8 and an The cotton mesh filter element 10 between the upper cover 9 and the contact between the cotton mesh filter element 10 and the breathing seat 8 and the upper cover 9 are all provided with a first sealing gasket 11, and an upper air outlet is arranged around the top of the breathing seat 8, and an upper air outlet is arranged in the middle. There is an upper air inlet, and the centrifugal separation device includes a connecting seat 1 for connecting the oil tank, a housing 2 arranged on the connecting seat 1 and a lower cover 3 arranged on the housing 2, and the housin...

The invention relates to an oil tank ventilator with a function of centrifugal separation. The oil tank ventilator includes a connection seat used for connecting an oil tank, a housing arranged on the connection seat and a lower cover arranged on the housing. The connection seat is provided with a vent hole, and the lower cover is provided with a threaded hole to connect the ventilator. The oil tank ventilator further includes a centrifugal separation mechanism arranged between the housing and the lower end, the centrifugal separation mechanism includes an installation plate, a centrifugal separating cylinder, an air inlet header pipe, an air inlet pipe, an air outlet pipe and an oil draining valve. By the arrangement of an oil-filter screen and the centrifugal separation mechanism, oil particles discharged from air can be effectively adsorbed in the oil-filter screen and the centrifugal separation mechanism, the concentration of the oil particles which reach the ventilator is reduced, and therefore the oil particles flowing out of an air outlet hole of the ventilator are prevented from polluting the environment and affecting the appearance of a hydraulic oil tank.
Description
technical field [0001] The invention belongs to the technical field of fuel tanks, and relates to a fuel tank respirator with centrifugal separation. 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, ...
