Description

Filter element of filter Technical Field The utility model relates to the technical field of filtering equipment, in particular to a filter element of a filter. Background The cross-flow filtration is that substances to be filtered move at high speed in the pore canal of the filter membrane with different apertures by a circulating pump, and the filtrate is filtered out in a tangential passing mode under the action of pressure, so that the filtrate forms turbulence due to the high-speed movement, the inner surface of a membrane rod is continuously washed, and a small amount of solid matters attached to the membrane are taken away, thereby preventing the filter membrane from being blocked and keeping the normal operation of filtration. The existing cross-flow filter element generally comprises a hollow tube, an upper sealing part, a lower sealing part and a dry hollow fiber ultrafiltration membrane, wherein the upper sealing part and the lower sealing part fix the two ends of the hollow fiber ultrafiltration membrane at the two ends of the hollow tube, an inlet is arranged on the lower sealing part, a backflow hole is arranged on the side wall of the hollow tube at the end of the upper sealing part, and an outlet is formed at the end part of the hollow fiber ultrafiltration membrane by penetrating through the upper sealing part. The principle is that the stock solution to be filtered enters the hollow tube from the inlet, and is permeated through the hollow fiber ultrafiltration membrane from outside to inside in the radial direction under the action of pressure difference in the axial conveying process of the hollow tube to become permeate, the permeate flows to the end of the upper sealing part in the hollow fiber ultrafiltration membrane and finally is discharged from the outlet, and the trapped substances are collected outside the hollow fiber ultrafiltration membrane and are conveyed along with the stock solution flow so that the end of the upper sealing part is discharged from the backflow hole. At present, in the existing cross-flow filter element, the hollow fiber ultrafiltration membrane is fixed inside the hollow tube and cannot be detached, the hollow fiber ultrafiltration membrane is easy to lose the use effect after long-term use, and then after the hollow fiber ultrafiltration membrane fails, the whole filter element also fails, so that the service life of the filter element is shorter. Disclosure of utility model The utility model aims to solve the problems, and provides the filter element of the filter, wherein the core body is convenient to assemble and disassemble, so that the filter element of the whole filter is convenient to replace, and the service life of the filter element of the filter is greatly prolonged. The filter element of the filter comprises a hollow tube, wherein a backflow hole is formed in the side wall of the hollow tube, a core body is arranged in the hollow tube, the core body comprises an upper sealing cover and a lower sealing cover, an outlet is formed in the upper sealing cover, an inlet is formed in the lower sealing cover, a hollow fiber ultrafiltration membrane is arranged between the upper sealing cover and the lower sealing cover, an installation shell is arranged on the hollow tube, an embedded block used for being embedded into the installation shell is arranged on the lower sealing cover, a plurality of buckles are arranged on the side wall of the embedded block, a plurality of clamping grooves used for buckling the buckles are formed in the side wall of the installation shell, the buckles can move along the radial direction of the embedded block, and a limiting assembly used for fixing the buckles is arranged on the embedded block.
