In order to achieve the purpose, the utility model provides a novel renewable filter element, which comprises an inner framework, a filter bag sleeved outside the inner framework, a filter bag sealing ring connected to the filter bag, a fixing ring sleeved outside the filter bag sealing ring, a gland and a plurality of O-shaped rings; the O-shaped ring is jointly extruded by the filter bag sealing ring and the fixing ring, and the pressing cover is connected with the fixing ring so that the inner framework and the fixing ring jointly extrude the filter bag sealing ring.

In some embodiments, the filter bag sealing ring is provided with a plurality of clamping grooves, and the O-ring is clamped in the clamping grooves.

In some embodiments, the endoskeleton includes at least one permeate tube, a center tube positioned inside the permeate tube, a spacer panel; the liquid permeating pipe is provided with a plurality of liquid permeating holes, the partition plate is connected to the top of the liquid permeating pipe, and the central pipe penetrates through the partition plate and is connected to the partition plate.

In some embodiments, the pocket seal ring is formed with a laterally extending end, the spacer plate end and the retainer ring co-extruding the laterally extending end.

In some embodiments, the partition plate is provided with a handle, and the handle extends out of the gland.

In some embodiments, the gland is provided with an internal thread, the fixing ring is provided with an external thread, and the internal thread and the external thread are matched.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a novel filter element can regenerate, the dismouting is nimble convenient, still possesses the blowback efficiency, can lift the filter cake outside off the filter bag, makes the filter bag regeneration recycle, in addition, through set up O type circle between filter bag sealing washer and solid fixed ring, has played better sealed effect, prevents the phenomenon of the outside infiltration of joint space.

Detailed Description

The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.

The novel renewable filter element shown in fig. 1-3 comprises an inner framework, a filter bag 1 sleeved outside the inner framework, a filter bag sealing ring 11 connected to the filter bag 1, a fixing ring 4 sleeved outside the filter bag sealing ring 11, a gland 3 and two O-shaped rings 5.

Two clamping grooves 110 are formed in the filter bag sealing ring 11, the O-shaped ring 5 is clamped in the clamping grooves 110 and is stable in structure, the O-shaped ring 5 is jointly extruded by the filter bag sealing ring 11 and the fixing ring 4, a sealing and waterproof effect is achieved, and water seepage from a connecting gap is prevented.

The endoskeleton includes a permeate tube 21, a center tube 22 located inside the permeate tube 21, and a spacer 23. The liquid permeating tube 21 is provided with a plurality of liquid permeating holes, the partition plate 23 is connected to the top of the liquid permeating tube 21, and the central tube 22 penetrates through the partition plate 23 and is connected to the partition plate 23.

The pressing cover 3 and the fixing ring 4 are connected to enable the inner framework and the fixing ring 4 to jointly press the filter bag sealing ring 11, specifically, the filter bag sealing ring 11 is formed with a transverse extending end 111, and the end part of the spacing plate 23 and the fixing ring 4 jointly press the transverse extending end 111 to form a sealing structure.
