Split-flow filtration type gas-liquid-solid three-phase cyclone separation apparatus

Abstract

The invention discloses a split-flow filtration type gas-liquid-solid three-phase cyclone separation apparatus, and is applied in the field of hydraulic fluid cleaning. The apparatus comprises a swirling barrel, an exhaust pipe installed on the top of the barrel, inflow pipes tangential to the upper wall of the barrel, a split-flow baffle plate inside the barrel, a lateral outflow pipe tangential to the lower wall of the barrel, a filtering apparatus with a filtering net arranged inside the filtering apparatus, and connected with the lateral outflow pipe, a funnel-shaped vertical outflow port communicating with the inside of the split-flow baffle plate, and a confluence pipeline. The apparatus firstly uses swirling centrifugal force to realize boundary aggregation of contamination impurities and formation of a gas core center, then separation of boundary impurity oil is completed by the split-flow baffle plate, and at the same time a high-speed swirling state required for bubble elimination is maintained, so that oil filtration is completed, bubble elimination is ensured, and three-phase synchronous efficient separation is realized. At the same time, the boundary contamination oil after filtration participates in the system oil circulation, and thus stability of a system flow is ensured. The apparatus structure is simple, separation is efficient, the equipment manufacturing cost is low, and application ranges are wide.

Description

technical field [0001] The invention relates to the field of hydraulic oil cleaning, in particular to a split-flow filter type gas-liquid-solid three-phase cyclone separation device. Background technique [0002] During the operation of the hydraulic system, due to the suction of the hydraulic pump or the high-speed jet flow at the valve port, a certain amount of gas will be mixed into the oil, causing cavitation of components, vibration and noise of the hydraulic system, and crawling of the hydraulic cylinder; at the same time, due to Due to the wear of hydraulic components and the intrusion of pollutants, the oil will be polluted by impurities, which will cause damage to the hydraulic components and reduce the service life. [0003] At present, the methods used to remove air bubbles and impurities in hydraulic oil are mainly divided into natural precipitation and sedimentation methods, filtration methods, etc. Moreover, at present, the separation of air bubbles and impuri...

AI Technical Summary

Problems solved by technology

Moreover, at present, the separation of air bubbles and impurities is mostly carried out separately, and the separation efficiency is low and the effect is limited.

The natural precipitation method is suitable for large-volume oil tanks. The precipitation of air bubbles and the sedimentation of impurities are slow, and the cleaning efficiency of the oil in the flowing state is low; directly installing a filter at the oil return port can effectively ensure the cleanliness of the oil, which is convenient and quick, but due to the natural In the oil return state, there is a pressure loss in the oil passing through the filter, and the flow rate slows down, which has a great impact on the oil flow state
