[0010] The beneficial effect of adopting the above technical solution is that the first cover body and the second cover body can be fastened to the pull rod by tightening the nuts at both ends of the pull rod.

[0011] In one embodiment, the ends of the first cover and the second cover that are away from each other are both provided with sealant for covering the portion where the pull rod passes through.

[0012] The beneficial effect of adopting the above technical solution is that the sealant covers the portion where the pull rod passes through the first cover and the second cover to block the gap between the pull rod and the first cover and the gap between the pull rod and the second cover.

[0013] In one embodiment, both ends of the pull rod are provided with external threads for threaded connection with a nut.

[0014] In one embodiment, a plurality of tie rods are evenly arranged along the circumferential direction between the first cover body and the second cover body.

[0015] The beneficial effect of adopting the above technical solution is that the force applied to the first cover and the second cover is more uniform due to the arrangement.

[0016] In one embodiment, the first cover and the second cover are both provided with a limiting boss at one end close to each other for abutting against the inner side of the frame.

[0017] The beneficial effect of adopting the above technical solution is that the limiting boss can limit the radial position of the skeleton to facilitate the fixation of the skeleton.

[0018] In one embodiment, the first cover and the second cover are both provided with a limiting ring at one end close to each other for abutting against the outside of the frameless filter element.

[0019] The beneficial effect of adopting the above technical solution is: such an arrangement can further limit the radial position of the skeleton-less filter element and the skeleton, thereby further fixing the skeleton-less filter element and the skeleton.

[0020] In one embodiment, the first sealing gasket is bonded to the first cover; and / or

[0021] The second sealing gasket is bonded to the second cover.

[0022] In one embodiment, a handle is connected to one end of the second cover away from the first cover.

[0023] The beneficial effect of adopting the above technical solution is that it is arranged in this way to facilitate extraction using the handle.

[0024] The beneficial effects of the present invention are:

[0025] The first cover body and the second cover body can be subjected to the pulling force of multiple pull rods to restrict the frameless filter element on the frame, so as to add the frame without changing the filter material stacking structure on the standard frameless filter element and without the need for additional processing of the filter material stacking, thereby improving the versatility of the frameless filter element.
