With the rapid development and application of advanced technologies, whether in life or industrial production, people have higher and higher requirements on fluid cleanliness, especially in the industries of chemical industry, new energy, pharmacy, food and the like. Most of the conventional filters are bag filters and filter element filters. These filters have been far from meeting the requirements of certain applications. The appearance of the cluster filter pipe widens the application field of the filter pipe. The bundling tube is generally composed of a filter bag for filtration, a liquid permeating tube with liquid permeating holes, and a central tube. Liquid to be filtered enters the liquid permeating pipe through the liquid permeating holes after being filtered by the filter bag, is gathered to the liquid collecting cavity at the bottom of the bundling pipe along with the trend of the liquid permeating pipe, and is finally discharged through the central pipe and the liquid outlet pipe connected with the central pipe.
Regarding the bundled filter tube, the applicant previously filed several related patents, but in the practical use, there was a problem that the bundled filter tube has a liquid permeation phenomenon at the connection gap, and therefore, the applicant studied and developed a new type of renewable filter element to solve the problem.

In order to achieve the purpose, the invention 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, wherein the filter bag is sleeved outside the inner framework; 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 invention has the beneficial effects that: the novel renewable filter element provided by the invention is flexible and convenient to disassemble and assemble, has a back flushing effect, can be used for disassembling filter cakes outside filter bags, and enables the filter bags to be recycled.

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 functional, methodological, 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.
Be equipped with the internal thread on the gland 3, be equipped with the external screw thread on the solid fixed ring 4, internal thread and external screw thread cooperate. Through the connection of the gland 3 and the fixing ring 4, the compression of the spacing plate 23 is realized, so that the spacing plate 23 and the fixing ring 4 more tightly press the filter bag sealing ring 11.
