Abstract

The utility model belongs to the technical field of filter elements, in particular to a filter element with replaceable filter materials, which comprises a supporting tube and a filter screen, wherein the filter screen is sleeved outside the supporting tube; an interface end cover is welded at one end of the supporting tube, external threads are arranged on the welding interface, a connecting ring is welded at one end of the filter screen, internal threads are arranged on the connecting ring, and the connecting ring is connected with the interface end cover through the internal threads and the external threads; the other end of the filter screen is connected with the supporting tube through a back cover. The utility model discloses it is convenient to dismantle, has broken away from the integrative not detachable problem that exists of traditional filter core and stay tube welding, when the filter screen blockking up and can not reach the requirement, changes the filter screen and just can continue to use, has improved the utilization ratio of other components, can reduce the cost of manufacture of filter core.

Description

Filter element with replaceable filter material

Technical Field

The utility model belongs to the technical field of the filter core, especially, relate to a filter core of removable filter media.

Background

As shown in figure 1, the integral structure of the traditional folding filter element is welded into a whole and is not detachable. The service life of the filter element is mainly determined by the service life of the filter screen. 98% of filter elements are blocked by the filter screen, and the filter elements can not be used any more and can only be discarded due to failure of the filter requirements. However, other parts of the filter element are not damaged, and theoretically, the possibility of multiple use exists. However, the filter element is welded into a whole, so that the filter element can only be integrally replaced, and great waste is caused. Therefore, the invention provides a filter element with replaceable aluminum.

SUMMERY OF THE UTILITY MODEL

The utility model provides a filter core of removable aluminum product, aim at realize the repetitious usage of components such as stay tube, interface end cover and back cover.

In order to achieve the above object, the utility model adopts the following technical scheme:

a filter element with replaceable filter material comprises a supporting tube and a filter screen, wherein the filter screen is sleeved outside the supporting tube;

an interface end cover is welded at one end of the supporting tube, external threads are arranged on the interface end cover, a connecting ring is welded at one end of the filter screen, internal threads are arranged on the connecting ring, and the connecting ring is connected with the interface end cover through the internal threads and the external threads;

the other end of the filter screen is connected with the supporting tube through a back cover.

Further, the back cover is of a stud structure.

Further, the connecting ring is of an integral stamping structure or a machining structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses an one end welding at the stay tube has the interface end cover of external screw thread, the one end welding at the filter screen has the internal screw thread go-between, be connected with the internal and external screw thread of interface end cover through the go-between, make the stay tube together fixed with the one end of filter screen, and the other end inserts in the stay tube through the back cover of screw column type, make the other end also be swing joint, adopt this kind of structure, it is convenient to dismantle, the detachable problem that traditional filter core and stay tube welding an organic whole exist has been got rid of, when the filter screen stops up and can not reach the requirement, it just can continue to use to change the filter screen, the stay tube has been improved, the utilization ratio of interface end cover and back cover, can reduce the cost of manufacture of filter core, make the product more have the competitiveness.
