Embodiment Construction

[0016] figure 1 A filter cartridge 10 is shown having a metal end member 30 in accordance with a preferred embodiment of the present invention. figure 2 show figure 1 Alternative embodiments of an embodiment. It should be noted that the invention is not limited to the embodiments shown, but that many other embodiments can be devised without departing from the scope of the appended claims.

[0017] Filter cartridge 10 includes filter element 20 . The filter element 20 is generally in the form of a porous fabric or its equivalent. The filter element 20 is generally arranged in a pleated form to increase the overall surface area. It should be noted, however, that the invention is not limited to pleated filter elements. The most common shape of filter element 20 is that of a hollow cylinder.

[0018] The filter cartridge 10 includes at least one metal end member 30 , although often two metal end members 30 are employed. If the filter element 20 is rectangular, four metal e...

Abstract

The filtration cartridge (10) comprises a filtration element (20) and a heat-resistant extension band (40) having a first (42) and a second longitudinal edge (44). The first edge (42) of the extension band (40) is attached along an edge (22) of the filtration element (20). In a first embodiment, a metallic cast end member (30) is formed by immersing the second edge (44) of the extension band (40) into molten metal. The molten metal is then allowed to solidify with the second edge (44) of the extension band (40) embedded therein. In a second embodiment, the extension band (40) is squeezed on a porous inner core (50) and an end plate (72) is welded on the end of the inner core (50). Providing filtration cartridges (10) with a metallic end member (30) allows increasing their resistance to mechanical shocks and increasing their maximum operating temperatures.

Description

Background technique [0001] As is well known, filtration cartridges have been widely used as fluid (liquid or gas) cleaning tools. For example in the case of gas, filter cartridges have effectively replaced filter bags made of porous paper or porous fabric to remove particles from the gas. [0002] In a factory, the treatment of dust from the operation process is usually handled by a dust collector that includes hundreds or even thousands of filter bags. As is known in the art, filter bags must be replaced periodically with new ones when they become full or clogged. Today, filter bags are gradually being replaced by filter cartridges, especially cylindrical filter cartridges with a pleated filter element consisting of a pair of ends that ensure a good seal of the filter cartridge in the container A member is supported or supported between the pair of end members. A distinct advantage of these filter cartridges over filter bags is that the surface area of ​​the filter elemen...
