Centrifugal automatic oil liquid filtering and circulating device

Abstract

The invention discloses a centrifugal automatic oil liquid filtering and circulating device. The automatic oil liquid filtering and circulating device comprises an underframe and an oil tank, a motor cavity is arranged at the lower end of the oil tank in a sealing manner, a turntable is arranged on the motor cavity, a centrifugal drum is fixedly arranged on the turntable, a pushing piston is arranged in the oil tank on the outer side of the centrifugal drum and is fixedly connected with pushing rods, oil outlet pipes are arranged at the lower end of the oil tank, and communicate onto an oil liquid cleanliness detection instrument. The structure of the centrifugal automatic oil liquid filtering and circulating device is driven by a motor I, then the centrifugal drum is driven to rotate, the oil liquid rapidly penetrates through a filtering plate under the action of the centrifugal force, the oil liquid treated by the centrifugal force is discharged to the oil tank, a motor II drives an eccentric turntable to rotate, the pushing rods are driven to move up and down, the filtered oil liquid in the oil tank penetrates through the oil outlet pipes and enters the oil liquid cleanliness detection instrument under the action of the pushing piston, when being detected to be qualified, the oil liquid is discharged through a discharging pipeline; and when being detected to be not qualified, the discharging pipeline is sealed, and the oil liquid enters the centrifugal drum again through a circulating pipeline to be filtered.

Description

technical field [0001] The invention relates to the technical field of oil filtration, in particular to a centrifugal automatic oil filtration and circulation device. Background technique [0002] The oil filter is installed on the pipeline to remove large solid impurities in the fluid, so that the machinery, equipment and instruments can work and operate normally, so as to stabilize the process and ensure safe production. It is usually used for oil filtration in gearboxes . [0003] At present, most of the existing oil filter devices adopt pressurized hydraulic filtration, so that the oil can quickly pass through the filter element under the action of pressure. In this way, the filter element needs to be cleaned or replaced frequently to maintain sufficient flow capacity for a long time. If the hydraulic pressure If it is too large, it will easily cause damage to the filter element, and if the hydraulic pressure is too small, it will affect the filtering effect. Unqualifi...

Problems solved by technology

[0003] At present, most of the existing oil filter devices adopt pressurized hydraulic filtration, so that the oil can quickly pass through the filter element under the action of pressure. In this way, the filter element needs to be cleaned or replaced frequently to maintain sufficient flow capacity for a long time. If the hydraulic pressure If it is too large, it will easily cause damage to the filter element, and if the hydraulic pressure is too small, it will affect the filtering effect. Unqualified oil cannot be circulated and filtered, resulting in extremely poor filtering effect, which has a particularly large impact on the gearbox, which may result in failure to shift gears, and may also cause damage to the gearbox. For this reason, we propose a centrifugal oil Liquid automatic filtration circulation device is used to solve the above problems
