Description

Filter cartridge capable of keeping filter element folding part stable

Technical Field

The utility model relates to the technical field of filter element manufacturing, in particular to a filter cylinder capable of keeping a folding part of a filter element stable.

Background

The filter cartridge is a special part in the filtering industry and is usually used for filtering foreign matter impurities such as sand, dust, water vapor and the like in the external environment, and at present, most of the filter cartridge consists of a sealing ring, an upper cover, an inner protective net, filter core paper, a lower end cover and the like.

The filter element paper can bear larger filtering pressure in the using process of the filter cartridge, if the filter element paper is not connected and fixed, the folding part of the filter element paper can be combined after long-term use, and the filtering efficiency is affected, so the filter element paper can be fixed in the following three modes in the prior art;

firstly, glass fiber cloth is wound on the peripheral surface of filter element paper, and then the glass fiber cloth is smeared at the joint of the filter element paper and the glass fiber cloth through structural adhesive for fixing, but the mode cannot apply too large tension and cannot press the joint between the glass fiber cloth and the filter element paper in the winding process so as to achieve the purpose of firm bonding, if too large tension or pressing force is applied, the glass fiber cloth is folded along the filter element paper, and if too small force is applied, the tightness of the glass fiber cloth cannot be ensured, so that the fixation of the folded part of the filter element paper cannot be realized;

secondly, grids Kong Lvwang are arranged on the inner side and the outer side of the filter element paper, and then the filter element paper and the grid hole filter screen are fixed through the structural adhesive, so that the filter element paper and the grid Kong Lvwang have good connection firmness, the two modes can not be used for keeping the space between the folding parts of the filter element paper stable, the filtering efficiency is affected due to the fact that the filtering areas of the different positions of the filter element paper are not uniform, and after the filter element paper is connected with the glass fiber cloth or the grid hole filter screen through the structural adhesive, the structural adhesive falls off after the filter element is used for a long time, so that the filter element paper is combined;

thirdly, the wire mesh cover is added in the filter element paper, so that the filter element paper has better molding stability, and the phenomenon of combining the filter element paper in the use process is reduced, but the folding filter element with the wire cannot be used in the environment with corrosive media, so that the use of the folding filter element with the wire is limited, and therefore, the three filter elements are problematic in use, and a new filter element capable of keeping the folding part of the filter element stable is needed.

Disclosure of Invention

The utility model aims to provide a filter cartridge capable of keeping a filter element folding part stable, which is used for solving the problems that the filter efficiency of the filter cartridge is reduced because the filter element folding part is combined after the filter cartridge is used for a long time and the interval between the filter element folding parts cannot be kept uniform in the prior art.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: the utility model provides a can keep filter core folding portion stable to strain, includes the bottom plate, is provided with circular folding filter core at the fixed bottom plate's of interior bottom surface, is equipped with the upper cover at folding filter core's upper end fixed cover, at folding filter core's internal face fixedly connected with inner support net, its characterized in that: the periphery fixed cover at folding filter core is equipped with the clamp, one end at the clamp is provided with the lock joint frame, one side that is located the lock joint frame is fixed being provided with first fixed frame on the clamp, one side that is located first fixed frame is fixed being provided with the second fixed frame on the clamp, the other end at the clamp is provided with the plugboard, the fixed support bar that is provided with a plurality of even annular arrangement at the internal face of clamp, the support bar sets up to the toper, one end integrated into one piece at the support bar is provided with the parting bead, the parting bead sets up to the diamond, the parting bead is used for evenly separating folding position of folding filter core, the opposite both sides surface of parting bead is laminated with folding position's of folding filter core surface, the diameter-reducing end of support bar is connected with the expanded end of parting bead, open at the surface of first fixed frame and second fixed frame has the through-hole, open at the surface of lock joint frame has fixed holding chamber, the plugboard stretches into the fixed holding intracavity of lock joint frame and rather than fixed grafting chamber one end, the surface at the fixed holding chamber one end of lock joint frame is provided with the closing mouth, the surface and plugboard laminating each other, one end face and plugboard's surface are provided with the parting bead, the inside the boss is used in the cooperation with the draw-in groove.

Further, in the embodiment of the utility model, the total length of the supporting strips and the separating strips is 3-5cm, the length of the separating strips is one third of the length of the supporting strips, and the intervals among a plurality of supporting strips are all set to be 2-3cm.

Further, in the embodiment of the present utility model, a plurality of reinforcing ribs are fixedly disposed on an inner wall surface of the clip, and the reinforcing ribs are disposed in an arc shape.

Further, in the embodiment of the utility model, a plurality of fastening grooves which are arranged at intervals are formed in the surface of one side, facing the boss, of the fixing accommodating cavity of the fastening frame, and clamping blocks are fixedly arranged on the surface of the boss and can be matched with the fastening grooves.

The beneficial effects of the utility model are as follows: according to the utility model, the interval between the folding parts of the folding filter element can be fixed through the clamp, and the folding parts of the folding filter element can be prevented from being combined in the using process, because the folding parts are combined with each other due to the fact that no fixing object is arranged in the folding filter element after folding, the filtering efficiency is reduced, if the folding parts of the folding filter element can be reduced and combined with each other through adding metal wires in the filter element, the folding filter element is limited due to the fact that the folding filter element with the metal wires cannot be used in an environment with corrosive mediums, and glass fiber cloth is connected to the outer peripheral surface of the folding filter element through structural adhesive, and the using limitation of the folding filter element after the metal wires is eliminated, but the glass fiber cloth is connected to the outer peripheral surface of the folding filter element through the structural adhesive, so that the glass fiber cloth is separated from the folding filter element due to the fact that the folding parts of the folding filter element are combined in the long-time filtering process. And, can prevent through the clamp that folding filter core from receiving the phenomenon that opens that leads to when great filtration pressure in the use, replaced the use of glass fiber cloth, can make folding filter core have better steadiness, and can make the folding part of folding filter core keep stable each other through dividing strip and support bar interval to avoided folding filter core emergence in the use to bind the phenomenon.
