Segmented Replacement Cartridge Filters

Abstract

The invention relates to a filter capable of replacing filter cores in a sectional form. The filter comprises a filter shell, and is characterized in that the upper end of the filter shell is connected with an upper cover, the lower end of the filter shell is connected with a lower cover, and the upper cover is provided with a water inlet and a water outlet; an upper layer of filter core and a lower layer of filter core are arranged inside the filter shell, the outer surface of each filter core is a fluctuated undulate surface, the upper end of each filter core is connected with an upper connection cover, and the lower end of each filter core is connected with a lower connection cover; an annular guide groove is formed between each filter core and the inner wall of the filter shell, and the water inlet is communicated with the guide groove; convex thorns are formed on the inner surface of the lower cover, a fourth sealing ring is respectively fixed on each convex thorn, and the fourth sealing rings push against the lower connection cover of the lower layer of filter core. The filter cores are replaced in a sectional form, so that the waste is reduced, and the service life of the filter core can be prolonged; moreover, the outer surface of the filter core is provided with a plurality of projections to form the fluctuated undulated surface, the filter area is increased by virtue of the projections, and the filter effect can be effectively improved.

Description

technical field [0001] The invention relates to a filter, in particular to a segmented replacement filter element, which belongs to the technical field of water purification equipment. Background technique [0002] In the prior art, the filter generally has a filter element placed in the filter housing, and the function of the filter to filter water is realized through the filter element. The current filter element is generally cylindrical, and can be a layer of filter elements, or multiple filter elements. When in use, the gravity of the water itself passes through the filter element to achieve the filtering effect, but this method is often unsatisfactory; and because the filter element is generally cylindrical with uniform thickness up and down, when the water flows downward under its own gravity, the filter element The lower part of the filter element tends to filter most of the water, while the upper part of the filter element only filters a small part of the water; thi...

When in use, the gravity of the water itself passes through the filter element to achieve the filtering effect, but this method is often unsatisfactory; and because the filter element is generally cylindrical with uniform thickness up and down, when the water flows downward under its own gravity, the filter element The lower part of the filter element tends to filter most of the water, while the upper part of the filter element only filters a small part of the water; this causes a waste of filter element filtration resources. Often when the upper part of a filter element has not absorbed any impurities, the lower part has exceeded loaded
