The existing oil absorption filter comprises a filter cover, a filter element, a shell, a bypass valve, a self-sealing valve, a filter element pollution and dyeing device and the like.
As shown in figure 1, when the hydraulic pump absorbs oil, the oil in the hydraulic oil tank firstly passes through the small hole on the shell 3, enters the filter element 2 through the self-sealing valve 5, and flows out of the oil absorption flange at the port A and enters the hydraulic system after the filtration treatment of the multi-layer filter materials. When the filter core is replaced or cleaned by the oil absorption filter, the filter cover 1 is unscrewed, the self-sealing valve 5 moves leftwards along with the filter core 2 under the action of the spring at the bottom of the filter until the oil tank is completely closed, an oil way of the oil tank is disconnected, and oil in the oil tank cannot flow outwards. After the filter element 2 is blocked by pollutants and the outlet pressure reaches a set value, the alarm device 6 alarms, and the hydraulic system still operates at the moment, so that the bypass valve 4 is opened to avoid the suction of the hydraulic pump. However, after the self-sealing valve 5 is closed, part of the oil still cannot be discharged from the A-port oil suction flange in the filter shell 3, and after the filter cover 1 is screwed off, the part of the redundant oil flows out along the filter cover, so that the discharged oil is inconvenient to collect and can pollute the filter cover.

The technical scheme is as follows: the self-sealing oil absorption filter comprises a shell, an oil inlet and an oil outlet are formed in the side edge of the shell, one end of the shell is detachably sealed through threads of a filter cover, a filter element is arranged in the shell, a self-sealing valve communicated with the oil inlet is arranged at the inner end of the filter element and abuts against the shell through a spring, an adjusting bracket is connected to the outer end of the filter element through a bracket spring, the adjusting bracket is pressed on the inner end face of the filter cover, an adjusting bolt is arranged on the filter cover and screwed in inwards from the outer end face, the adjusting bracket is extruded, the self-sealing valve is opened/closed through screwing in/screwing out of the adjusting bolt, and an oil drain port is further formed in the side wall of the shell.
Further, the adjusting support is of a groove structure, the support spring is arranged in the groove, a positioning groove corresponding to the outer wall of the adjusting support is arranged in the filter cover, and the adjusting support is arranged in the positioning groove.
Further, the outer end of the filter element is provided with a filter element support, and a groove at the outer end of the filter element support is used for placing a support spring.
Further, the inner wall of the filter cover is provided with a positioning groove for sliding connection of the outer wall of the filter core bracket.
Further, the adjusting bolt is positioned at the center of the filter cover.
Further, the oil drain port is circumferentially arranged at a plurality of angles on the side wall of the shell.
The beneficial effects are that: compared with the prior art, the utility model has the advantages that: under the condition that the filter cover is not opened, firstly discharging the oil liquid remained in the shell, enabling the oil-free liquid to flow to the filter cover and flow out, and enabling the oil liquid not to pollute the filter cover or the environment; the oil drain ports are arranged at multiple angles, and the proper oil drain port can be selected to be connected with the oil drain pipe according to the installation angle of the oil suction filter, so that the adaptability is higher; the reliability of the overall filter increases.
