Description

Technical Field

[0001] The utility model relates to the field of filtration, and specifically, to a stacked filter screen. Background Art

[0002] The stacked filter is installed in the filter and can be used for primary filtration, decarbonization, deep filtration, semi-fine filtration, and fine filtration. The stacked filter is composed of multiple layers of overlapping filter screen plates and filter frames. The screen plate holes are punched by computer, and the hole density is small and uniform, which can ensure that the filter material pressure on each layer of the filter screen plate is uniform, so that the filtration accuracy is excellent.

[0003] However, the existing stacked filter screens have certain defects in actual use. Most of them are stacked together, which makes it inconvenient to disassemble them individually. After long-term use, individual filter screens will be damaged. If they are not replaced, the filtering effect will be affected. If they are replaced, the entire screen needs to be replaced and cannot be replaced individually, which is relatively costly. Utility Model Content

[0026] See also Figure 1-Figure 5 In order to facilitate the assembly operation of the filter body 3, to facilitate regular disassembly, cleaning or replacement thereof, and to facilitate assembly and use, mounting card slots 5 for mounting components are equidistantly provided in the two side walls of the frame 1, and mounting card plates 11 that can be conveniently inserted and moved in the mounting card slots 5 are welded on both sides of the mounting frame 2. In order to ensure the effect of plugging, auxiliary positioning and fixation can be performed after plugging. An auxiliary slot 8 for an auxiliary component is provided at one end of the interior of the frame 1, and a fixed magnetic suction 10 is bonded inside the slot and at the end of the mounting frame 2. The two magnetic forces are opposite, and can assist in attraction and fixation after plugging, thereby further improving the effect of plugging.

[0027] See also Figure 1-Figure 5 In order to ensure the firmness during assembly and facilitate the subsequent disassembly of a single filter body 3, a rotating member 14 is bonded to the other end of the mounting frame 2 (the end away from the fixed magnetic attraction 10), and a sleeve 13 is provided for rotation (the principle of the rotating member 14 is the same as that of the bearing, which is a relatively mature technology and will not be described in detail here). A sliding cavity 16 of a reset assembly is provided in the sleeve 13, and a moving plate 17 is installed inside the sliding cavity 16 through a spring 15, which can slide conveniently in the sliding cavity 16. In order to facilitate the subsequent rotation of the rotating plate 6 and the sleeve 13, the moving plate 17 can be easily moved. A guide block 19 is bonded to the side surface of the movable plate 17, and a guide groove 18 is provided inside the sliding cavity 16 to facilitate the sliding of the guide block 19. A sliding rod 9 is fixed to the end of the movable plate 17 away from the spring 15. The sliding rod 9 slides out of the sliding cavity 16 and is welded and fixed to the rotating plate 6. An empty groove 4 adapted to the rotating plate 6 is provided on the frame 1, which can facilitate the pulling and removal of the rotating plate 6. The limit blocks 12 of the positioning assembly are symmetrically welded on the side surfaces of the rotating plate 6, and a positioning hole 20 is provided on the side wall close to the frame 1, and a positioning block 7 for positioning with the positioning hole 20 is bonded to the frame 1.

[0028] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0029] In summary, with the aid of the above technical solution of the utility model, when assembling the filter body 3, the installation frame 2 is inserted into the empty slot 4, and the installation card plate 11 is installed into the installation card slot 5 to complete the plug-in operation, and the fixed magnetic suction 10 enters the auxiliary slot 8, and is attracted and fixed with another fixed magnetic suction 10 to complete the initial installation and positioning. At this time, the installation frame 2 is first pressed, and then the rotating plate 6 is pulled, and the slide bar 9 and the movable plate 17 slide in the sliding cavity 16, and the guide block 19 slides in the guide groove 18. The spring 15 is stretched by force to store potential energy, and then the rotating plate 6 can be moved out of the empty slot 4, and the rotating plate 6 is rotated to cooperate with the limit of the guide block 19 and the guide groove 18. , the sleeve 13 can be rotated on the rotating member 14, and the positioning hole 20 on the limit block 12 can be aligned with the positioning block 7. At this time, it is reset under the action of the potential energy of the spring 15, and the positioning block 7 is plugged into the positioning hole 20. At this time, the spring 15 is still in a stretched state to ensure the effect of the engagement, thereby completing the positioning and fixing, and does not affect the subsequent filtering use. When it is necessary to disassemble, replace or clean it separately, by pulling the rotating plate 6, the limit block 12 can be moved outward, and the positioning hole 20 leaves the positioning block 7, and then it is rotated and pulled outward, and the fixed magnetic suction 10 is separated by force, and then the installation frame 2 can be pulled out, which is convenient for cleaning or replacing the filter body 3, which is more convenient.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
