[0006] Furthermore, each of the pressure rings is fixedly connected with a plurality of connecting arms, and the plurality of connecting arms are arranged in a circle.

[0007] The beneficial effects of the utility model are as follows: since the cross bar is arranged inside the hook, under the action of the spring, the pressure ring, the upper edge of the filter bag and the upper edge of the mesh frame are pressed tightly against the step hole, so that the upper edge of the filter bag and the upper edge of the mesh frame are sealed to ensure the filtering effect; the hook position is reasonably designed, and when the pressure ring needs to be removed or installed, it is only necessary to rotate the cross bar clockwise or counterclockwise, which is very convenient; and the spring, the connecting arm and the cross bar are detachably connected, which is convenient for processing, manufacturing, assembly or disassembly.

DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0013] like Figure 1-Figure 3 As shown, a filling filter comprises a shell 1, an end cover 2, a partition 11, a mesh frame 3, a filter bag 4 and a pressing member. The top of the shell 1 is connected to the end cover 2 through a flange, the partition 11 is horizontally arranged in the shell 1, a liquid inlet 12 is arranged on the side of the shell 1 above the partition 11, and a liquid discharge port 13 is arranged at the bottom of the shell 1. Seven step holes 111 are transparently arranged on the partition 11, and the mesh frame 3 is installed in the step holes 111. The filter bag 4 is installed in the mesh frame 3, and the upper edge of the filter bag 4 is laid on the upper edge of the mesh frame 3. Above the partition 11, each filter bag 4 is provided with a There is a clamping piece, which includes a clamping ring 5, a spring 6, a longitudinal rod 7, a cross rod 71 and two hooks 8. The outer side of each step hole is distributed with two hooks 8 along its own radial direction and the openings of the two hooks 8 are arranged oppositely. The clamping ring 5 fits the upper edge of the filter bag 4. The top of the clamping ring 5 is fixedly connected with a transverse connecting arm 51. The longitudinal rod 7 is penetrated by the connecting arm 51. The bottom of the longitudinal rod 7 is threadedly connected with a bolt 72. The top of the longitudinal rod 7 is fixedly connected with a cross rod 71. A spring 6 is sleeved on the longitudinal rod 7 between the cross rod 71 and the connecting arm 51. The spring 6 presses the cross rod 71 tightly against the two hooks 8.

[0014] Since the cross bar 71 is pressed against the hook 8, under the action of the spring 6, the pressure ring 5, the upper edge of the filter bag 4 and the upper edge of the mesh frame 3 are pressed against the step hole 111, so that the upper edge of the filter bag 4 and the upper edge of the mesh frame 3 are sealed to ensure the filtering effect; the position of the hook 8 is reasonably designed, and when the pressure ring 5 needs to be removed or installed, it is only necessary to rotate the cross bar 71 clockwise or counterclockwise, which is very convenient; and the spring 6 is detachably connected to the connecting arm 51 and the cross bar 71, which is convenient for processing, manufacturing, assembly or disassembly.

[0015] In this embodiment, two connecting arms 51 are fixedly connected to each pressing ring 5 . The two connecting arms 51 are arranged in a circle, which is reasonably designed and improves the uniformity of the force applied to the pressing ring 5 .
