Embodiment

[0030] Embodiment: a kind of filter element 100, as figure 1 and figure 2 As shown, it includes a filter body 101 and a connector 102. The filter body 101 is a cylindrical filter body with a cavity 1011 in the middle, and the cavity 1011 is a through hole extending from the lower end of the filter body 101 to the upper end. , the connecting piece 102 has two and is respectively embedded in the upper end and the lower end of the filter body 101, the connecting piece 102 is a stepped tubular connecting piece formed by connecting the upper tube 1021 and the lower tube 1022, and the The inner diameter of the lower tube 1022 matches the outer diameter of the upper tube 1021, the outer diameter of the lower tube 1022 matches the cavity 1011 of the filter body 101, and is located on the upper end of the connector 102 at the upper end of the filter body 101. The tube 1021 protrudes from the upper end of the filter element body 101 .

[0031] In this embodiment, the connectors 102 a...

Abstract

The invention discloses a filter element and a multi-stage composite filter element formed by the same. The filter element comprises a filter body and connecting pieces, wherein the filter element body is a cylindrical filter body with a cavity in the middle, and the connecting piece is provided with an upper end and a lower end which are respectively embedded in the filter element body; the connecting piece is a stepped tubular connecting piece formed by connecting an upper pipe and a lower pipe, and the inner diameter of the lower pipe is matched with the outer diameter of the upper pipe; and the outer diameter of the lower pipe is matched with the cavity of the filter element body, and the upper pipe of the connecting piece positioned at the upper end of the filter element body protrudes out of the upper end of the filter element body. The two ends of the filter element are embedded with the connecting pieces, and different sizes and different specifications of filter elements can be freely combined according to the waste liquid treatment capacity to meet the flow demand. The length of the composite filter element is not limited and the filter elements are combined completely according to the need, and the fast butting, accurate positioning and convenient installation can be realized in the combination process, thus obviously improving the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of filter elements, in particular to a filter element and a multi-stage composite filter element composed of the filter element. Background technique [0002] At present, the filter elements widely used in domestic water purification equipment are integrated water purification filter elements, which integrate multiple filter materials into one body, have multiple filtering effects, and can improve space utilization, reduce the number of filter cartridges, and reduce production costs. However, in the existing integrated water purification filter element, if a certain filter element material fails and needs to be replaced, the entire filter element must be replaced, that is, multiple materials of the filter element body are replaced at the same time, so as to cause waste of other available filter materials. [0003] In order to solve the above problems, a filter element structure composed of a plurality of sma...
