Detailed Implementation

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0022] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0023] A filter paper mounting structure for a filter washing and drying machine, such as Figure 1 As shown, the system includes a chassis 1, with a perforated plate 2 fixed above the chassis 1, forming a media collection chamber between the perforated plate 2 and the chassis 1. A drain pipe 101 connected to the media collection chamber is provided on the chassis 1. A filter medium 3, which is filter paper, is fixed above the perforated plate 2. A lower flange 4 is fixedly connected to the outer periphery of the chassis 1. An upper flange 5 is detachably connected to the upper end of the lower flange 4 via threaded fasteners. The upper flange 5 is used for fixed connection to a container. The filter medium 3 is circumferentially located between the upper flange 5 and the lower flange 4, and a first sealing ring 6 is provided between the upper end face of the filter medium 3 and the upper flange 5. A second sealing ring 7 is provided between the upper flange 5 and the lower flange 4 on the outer periphery of the filter medium 3. The particulate medium enters the area above the filter medium 3 in the middle of the upper flange 5. After being filtered by the filter paper, the filtrate enters the medium collection chamber through the perforated plate 2 and is then discharged through the drain pipe 101. The particulate medium remains above the filter paper. When the filter medium 3 needs to be replaced, the threaded fasteners are removed and the base plate 1 is taken off to replace the filter paper. This is convenient, quick, and has low production costs.

[0024] Specifically, such as Figure 2 , Figure 3 As shown, the lower flange 4 has several lower U-shaped openings 401 on its outer periphery, and the upper flange 5 has several upper U-shaped openings 501 at corresponding positions on its outer periphery. The threaded fasteners are bolts 801 and nuts 802. The bolts 801 are hinged to the lower end of the lower flange 4 or the upper end of the upper flange 5. The bolts 801 are turned into the lower U-shaped openings 401 and the upper U-shaped openings 501, and the nuts 802 are used to fasten the upper flange 5 and the lower flange 4. This design facilitates the assembly and disassembly of the upper flange 5 and the lower flange 4, resulting in higher filter paper replacement efficiency.

[0025] Furthermore, a hinge ring 9 is fixed to the bottom of the lower flange 4 at the lower U-shaped opening 401, and the bolt 801 is hinged to the hinge ring 9. The hinge ring 9 and the lower flange 4 are fixed by several fasteners, which are connected to the lower flange 4 between adjacent lower U-shaped openings 401 by screws, making the overall structure simple and easy to disassemble and assemble.

[0026] Furthermore, the upper end of the inner circumference of the lower flange 4 is provided with a limiting groove that is adapted to the thickness of the perforated plate 2. The perforated plate 2 is circumferentially limited within the limiting groove. After the perforated plate 2 is placed in the limiting groove, the upper surface of the lower flange 4 is flush with the upper surface of the perforated plate 2, so that the filter paper is laid flat and fixed.

[0027] Furthermore, the lower end face of the upper flange 5 is provided with a first sealing groove and a second sealing groove corresponding to the first sealing ring 6 and the second sealing ring 7, respectively. The first sealing ring 6 and the second sealing ring 7 are embedded in the first sealing groove and the second sealing groove. The first sealing ring 6 and the second sealing ring 7 are O-rings, and the first sealing groove and the second sealing groove are dovetail grooves. The dovetail groove structure of the first sealing groove and the second sealing groove effectively fixes the O-ring structure of the first sealing ring 6 and the second sealing ring 7, facilitating assembly.

[0028] Furthermore, at least two second sealing rings 7 of different diameters are provided between the upper flange 5 and the lower flange 4. The multi-seal structure forms an effective and reliable sealing effect.

[0029] like Figure 3 As shown, the upper surface of the chassis 1 is provided with a medium collection tank 102. A guide strip 103 protrudes upwards from the bottom surface of the medium collection tank 102, and a drain port 104 connected to the drain pipe 101 is located at the center of the medium collection tank 102. Furthermore, the upper surface of the guide strip 103 is attached to the bottom surface of the perforated plate 2, providing both guidance and reliable support. Furthermore, the bottom surface of the medium collection tank 102 has a centripetal flow slope. Here, the slope change of the bottom surface of the medium collection tank 102 is small, avoiding a significant impact on the overall thickness of the chassis 1. Specifically, the centripetal flow slope can be formed by a conical surface or by a gradually changing annular stepped height.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
