Description

Filter residual liquid filtering component with double independent pipelines Technical Field The utility model relates to the field of filter assemblies, in particular to a filter residual liquid filter assembly with double independent pipelines. Background After the traditional filter is finished, partial accumulated liquid (hereinafter referred to as residual liquid) can be remained at the bottom of a filtering tank body (tank body of the filter), the residual liquid is filtered and discharged by pressurizing the inside of the filtering tank body in a mode of injecting compressed gas, but the problem that the gas is discharged from a hole of a filter cylinder on a filter element when not reaching the bottom of the tank can exist in a mode of pressurizing the gas to filter the residual liquid, the pressure is insufficient, and partial accumulated liquid still in the tank cannot be filtered, so that the output of liquid is influenced. Therefore, the application number 2024215857168 discloses a filter element capable of improving the output of liquid, in the normal state, liquid which enters the upper filter cavity and is filtered by the lower filter cylinder is discharged through a notch by a central pipe, liquid is discharged in a mode of injecting compressed gas after the filtration is finished, and when liquid still exists at the bottom of the filter tank body in the mode, residual liquid which enters the lower filter cavity after the filtration of the lower filter cylinder can be discharged through a sleeve, so that the liquid accumulation in the tank is avoided, and the output of the liquid is prevented from being influenced. However, the above structure for discharging residual liquid may affect normal filtration, specifically, in the normal filtration process, the filtrate needs to enter the upper filter cavity after being filtered by the filter cartridge, and then flows into the central tube through the gap in the middle of the central tube to be discharged. Because the sleeve is nested in the central part inside the central tube, and the central tube extends out from the bottom of the sleeve, the structure directly occupies the internal circulation space of the central tube, namely the effective flow area of the cross section of the central tube is reduced due to the existence of the sleeve, the normal filtering speed is affected, and in addition, the nested structure of the sleeve and the central tube possibly forms a flow channel shrinkage effect near a notch, so that turbulent flow is generated when filtrate enters the central tube, and the energy loss is further aggravated.
