Fig. 6 is the perspective view of other local members of Fig. 4, promptly seals the bottom of the canned filter course of fold.

What Fig. 7 showed is to bow from eminence toward lower to see the vertical view of the filter of being furnished with the filter element on the gripper shoe of being installed in.

The specific embodiment:

According to picture mentioned above, Fig. 1 can illustrate fully that dedusting filter is furnished with a plurality of filter elements, and in this tubulose special construction, parts abut against and are placed in together in the same structure.Each parts 2 comprises a filtering bodies of being furnished with fold tubulose filter course 3, and filtering bodies is parallel each other.The bottom of each filter course all seals, and the other end that is used to export the air that has purified is an opening.Some impurity can be stopped in the outside of filter course.

Each filter element 2 comprises the ring support 4 of a plastic material compacting in addition, and it is placed in the filter body and is bonded to the openend of filter course 3.

These parts 2 all are concentrated on the gripper shoe 5 with a plurality of open-works, and each open-work 6 all is connected with parts, and ring support 4 all has been installed in each hole.

In the outside each ring support 4 all be contained in to around extend and form between them the groove 41 of certain angle.Each groove all will axially embed and rotate fixing mode and carry out the bayonet socket connection, and gives prominence to the outside, edge 61 at corresponding open-work.The groove 41 of each ring support all has an axial import 42 so that axially insert at outstanding position 61.Groove 41 on each support and the ledge 61 of corresponding open-work internal edge is all angled lays is in order to make each groove can be connected with spinning movement and separate according to identical insertion simultaneously with ledge like this.

Each ring support 4 all is installed between two groups of grooves, and two groups of grooves 41 are one high and one low: thus every group of groove all between the axially-aligned shape have a certain degree.The ledge 61 of hole internal edge is to be connected with one group or other one group of groove selectively: if support selects high-order groove to be connected on the gripper shoe, so just have from bottom to top support to be inserted into (Fig. 1) in the air, otherwise then select Lower tank (Fig. 7).The axial inlet of one group of groove all is in same direction, and the import of another group then is in opposite direction, like this can from last or by under have selection that support 4 is inserted on the gripper shoe 5 the corresponding open-work 6.

Each ring support 4 all is furnished with a ring washer 7, and this packing ring 7 is installed in collar flange place 43 and radially can seals corresponding open-work 6 edges with putting up.Packing ring 7 has one to the groove that extends all around in the outside, it is used in the flange place 43 in the ring support outside.The flange place has two to the groove 44 that extends all around, one last, one following, main with being that packing ring becomes two flange places 71 of opposing face, so just can form two ledges, be the C shape substantially, so just can hinder packing ring 7 and run out of, particularly filter is being implemented the pressure-air clean-up phase from edge 43.According to support is to locate to be inserted on the gripper shoe by eminence (Fig. 7) or by low (Fig. 1), selects the sealing surface of packing ring, upside 72 or downside 73,

Ring support 4 inside are furnished with a plurality of primary structural components, and can play fastening effect in lining portion protrusion formation ring-type 45, can manually rotate when implementing to connect and separate.

The edge of ring support 4 is furnished with bayonet type parts 46, and has drawn back certain distance with support, and shape has a certain degree, and is connected with external equipment by taking off mouthful groove, such as the compressed air pipe of cleaning filter.

Each filter element 2 all comprises a bottom 8, is connected at the blind end of bottom filtering surface 3, also comprises a star disk 81, a fold of the corresponding fold filtering surface in each summit on the disk.

Bottom 8 is made by plastic material, is sticked together by the blind end of viscose glue with it and filtering surface.It is in order to hold the end of filtering surface that the star-shaped rim of disk has a ledge 82.Disk has an axial protrusion 83 to be used for the end of inner limiting filter face in addition, and

protrusion

82 and 83 can be delimited the control area by edge, so that utilize viscose glue to come the adhesion filtering surface.The bottom of star disc type can make the fold face open, thereby make to allow gap is freely arranged between the pleat, and when cleaning, the impurity that breaks away from filtering surface just can be removed easily.

Filter element 2 also comprises the netted tubular annex 9 that plastics are made in addition, it is installed in the inside of tubulose fold filtering surface and plays reinforcement effect, the star ring that plays restraining function is placed in zone line, and all corresponding fold of fold face accordingly in each summit on the ring.

Each filter element part 2 is inserted (making ledge 61 enter into import 42), and also rotation is fixing on gripper shoe 5, both is linked together, just as buckle connects.Invention can make a large amount of modifications when specifically practicing, but the details of manufacture view can not run out of the inventive concept scope hereto.
