[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0036] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] The existing weighing components in stacked filters are only used to weigh the stacked filter itself. When there are a large number of reactants involved, it is impossible to accurately control the reaction feed, which leads to a decrease in the purity of the product or even reaction failure.

[0038] Based on this, this application provides a stacked filter 100, which has the advantage of being easy to disassemble for cleaning or replacement of filter paper.

[0039] Please refer to Figures 1 to 7 As shown, a stacked filter 100 provided in an embodiment of this application includes: a filter cartridge 10, a stacked filter assembly 20, a linkage assembly 30, and a drive assembly 40.

[0040] The filter cartridge 10 includes a cartridge body 11 and an upper cover 12. The cartridge body 11 encloses a filtration space 111, and the upper cover 12 is disposed above the cartridge body 11 to seal the filtration space 111. The stacked filter assembly 20 has an opening 201 at its center that penetrates the stacked filter assembly 20.

[0041] The upper and lower ends of the linkage component 30 pass through the opening 201 and are located above and below the stacked filter component 20, respectively. The lower end of the linkage component 30 abuts against the lower part of the stacked filter component 20.

[0042] The drive component 40 is connected to the upper end of the linkage component 30. The drive component 40 is used to drive the linkage component 30 to move up and down, thereby driving the stacked filter component 20 to move up and down.

[0043] The stacked filter 100 provided in this application, by setting the linkage component 30 and the drive component 40 to cooperate with the stacked filter component 20, can quickly remove the stacked filter component 20 from the cylinder 11 for cleaning or replacement of the filter paper, which is more convenient and faster.

[0044] Preferably, in one embodiment of the stacked filter 100 provided in this application, the linkage assembly 30 includes a central rod 31, a first retaining ring 32, and a connecting pipe 33. The upper and lower ends of the central rod 31 pass through the opening 201 and are located above and below the stacked filter assembly 20, respectively. The first retaining ring 32 is connected to the upper end of the central rod 31, and the drive assembly 40 is connected to the first retaining ring 32. The connecting pipe 33 is connected to the lower end of the central rod 31, and abuts against the lower part of the stacked filter assembly 20. The connecting pipe 33 is used to connect to the discharge pipe (not shown) of the stacked filter 100.

[0045] The stacked filter 100 provided in this application includes a central rod 31, a first handle ring 32, and a connecting pipe 33. The central rod 31 passes through the opening 201 and is located above and below the stacked filter assembly 20. The first handle ring 32 and the connecting pipe 33 are connected to the upper and lower parts of the stacked filter assembly 20, respectively. The first handle ring 32 is also connected to the drive assembly 40, so that the drive assembly 40 can drive the entire stacked filter assembly 20 to move up and down by driving the first handle ring 32, thereby facilitating the cleaning, maintenance, and filter paper replacement of the stacked filter assembly 20.

[0046] Optionally, in one embodiment of the stacked filter 100 provided in this application, the upper cover 12 is provided with a second ring 121 and a handle 122 connected to the upper cover 12. The second ring 121 is used to connect to the drive assembly 40 so that the drive assembly 40 can drive the upper cover 12 to move up and down. The handle 122 is used for manually lifting the upper cover 12.

[0047] The stacked filter 100 provided in this application includes a second handle 121 and a handle 122. The second handle 121 is connected to the drive assembly 40 so that the drive assembly 40 can drive the upper cover 12 to move up and down. The handle 122 is used to manually lift the upper cover 12, making it easy to open the upper cover 12. At the same time, since the cylinder 11 provided in this application is equipped with an upper cover 12, and the stacked filter 100 provided in this application only requires opening the upper cover 12 to maintain and clean the components located inside the cylinder 11, compared to opening from below and maintaining the components inside the cylinder 11, the filtrate inside the cylinder 11 will not leak out after opening the cylinder 11. This reduces material waste and saves costs when filtering some high-value materials.

[0048] Preferably, in one embodiment of the stacked filter 100 provided in this application, the stacked filter assembly 20 includes a filter layer 21, and the filter layer 21 has an opening 201 penetrating through the center of the filter layer 21. Multiple filter layers 21 are provided, and the multiple filter layers 21 are stacked vertically.

[0049] The stacked filter 100 provided in this application forms a stacked filter assembly 20 by setting multiple filter layers 21 stacked vertically. The multi-layer filter layer 21 stacked design can form a gradient filtration effect, enabling the stacked filter 100 provided in this application to first intercept large particles of impurities and then filter small particles, thereby improving the overall filtration accuracy of the stacked filter 100. At the same time, the multiple filter layers 21 stacked vertically can maximize the filtration area in the limited filtration space 111, thereby increasing the filtration volume per unit time and improving the working efficiency of the stacked filter 100.

[0050] Preferably, in one embodiment of the stacked filter 100 provided in this application, the filter layer 21 includes a filter frame 22 and a filter plate 23 stacked vertically. When using the stacked filter 100 provided in this application, the filtration effect of the stacked filter 100 is improved by placing filter paper (not shown) between the filter frame 22 and the filter plate 23. The filter frame 22 includes an outer frame 221, an inner frame 222, and a support tube 223. The outer frame 221 and the inner frame 222 are annular. Multiple support tubes 223 are provided and arranged circumferentially between the outer frame 221 and the inner frame 222. The filter plate 23 includes a frame portion 231, an annular portion 232, and a filter plate portion 233. The filter plate portion 233 is disposed between the frame portion 231 and the annular portion 232. Multiple filter holes 2330 are provided on the filter plate portion 233, and the multiple filter holes 2330 are evenly distributed on the filter plate portion 233.

[0051] The stacked filter 100 provided in this application is configured with a filter frame 22 and a filter plate 23. The filter frame 22 includes an outer frame 221, an inner frame 222, and a support tube 223. Since the filter plate 23 needs to withstand the pressure of the fluid during operation, the support tube 223 can provide support for the filter plate 23, thereby preventing the filter plate 23 from bending, denting, or breaking due to excessive fluid pressure, which would lead to filter plate 23 failure. At the same time, the support tube 223 forms a rigid support structure, which can offset the impact of fluid pressure on the filter plate 23, ensuring that the filter plate 23 always maintains a flat filter surface, thereby maintaining the filtration efficiency of the filter plate 23.

[0052] Preferably, in one embodiment of the stacked filter 100 provided in this application, the filter plate 23 includes a first filter plate 24 and a second filter plate 25 stacked vertically. The first filter plate 24 is located above the second filter plate 25, and a filtrate space is formed between the first filter plate 24 and the second filter plate 25. An opening 201 is provided at the center of the first filter plate 24 and the second filter plate 25, and an outlet 251 is provided at the opening of the second filter plate 25. The outlet 251 communicates with the inlet (not shown) of the stacked filter 100, and the filtrate flows out from the outlet 251 into the filtrate space, filling the filtration space 111 within the entire cylinder 11. The outlet 251 is located within the filtrate space.

[0053] The stacked filter 100 provided in this application consists of a first filter plate 24 and a second filter plate 25, which are stacked to form the filter plate 23 described in this application. The first filter plate 24 and the second filter plate 25 form a filtrate space. The second filter plate 25 is provided with an outlet 251, so that the filtrate flows out of the outlet 251 and is first filtered by the first filter plate 24 and the second filter plate 25 before filling the entire filtration space 111, thereby improving the filtration effect.

[0054] Optionally, in one embodiment of the stacked filter 100 provided in this application, the first filter plate 24 and the second filter plate 25 are connected by embedding, and the first filter plate 24 is embedded in the second filter plate 25.

[0055] The stacked filter 100 provided in this application sets the first filter plate 24 and the second filter plate 25 to be embedded, so that each component can be disassembled and cleaned without dead angles, thereby reducing the cleaning difficulty and improving the installation or disassembly speed.

[0056] Preferably, in one embodiment of the stacked filter 100 provided in this application, the outlet 251 is rectangular in shape. The first filter plate 24 and the second filter plate 25 are provided with a plurality of filter holes 2330, the inner diameter of the filter holes 2330 being greater than or equal to 5 micrometers and less than or equal to 100 micrometers.

[0057] Optionally, in another embodiment of the stacked filter 100 provided in this application, the shape of the outlet 251 can be circular or square, etc.

[0058] For example, the inner diameter of the filter pore 2330 can be 5 micrometers, 25 micrometers, 50 micrometers, 75 micrometers, 100 micrometers, etc., and this application does not limit it.

[0059] The stacked filter 100 provided in this application improves filtration efficiency by setting the shape of the liquid outlet 251 to be rectangular, thereby increasing the liquid outlet area and accelerating the liquid outlet speed. At the same time, by setting the inner diameter of the filter pores 2330 to be greater than or equal to 5 micrometers and less than or equal to 100 micrometers, the pore size distribution of the filter pores 2330 on the filter plate portion 233 can be maximized, thereby forming dense micrometer-level filtration channels and improving the filtration capacity of the stacked filter 100 provided in this application.

[0060] Optionally, in one embodiment of the stacked filter 100 provided in this application, the surface of the filter layer 21 is provided with an oleophobic coating or a hydrophilic modified layer.

[0061] The stacked filter 100 provided in this application provides an oleophobic coating or a hydrophilic modification layer on the surface of the filter layer 21. When filtering oily filtrates, the oleophobic coating reduces the adhesion of the filtrate to the filter layer 21, thereby reducing the difficulty of subsequent cleaning of the filter layer 21. When filtering colloidal solutions, the hydrophilic modification layer on the surface of the filter layer 21 reduces the adhesion of the filtrate to the filter layer 21, thereby reducing the difficulty of subsequent cleaning of the filter layer 21.

[0062] Optionally, in one embodiment of the stacked filter 100 provided in this application, the drive assembly 40 includes a drive member 41, a connector 42, and a hook 43. The hook 43 is connected to one end of the connector 42, and the opposite end of the connector 42 is connected to the drive member 41. The hook 43 is used to connect to the upper end of the linkage assembly 30.

[0063] The stacked filter 100 provided in this application, by setting a drive component 40, which includes a drive component 41, a connector 42 and a hook 43, drives the linkage component 30 and the stacked filter component 20 to move smoothly up and down, preventing shaking or other phenomena when the linkage component 30 and the stacked filter component 20 move.

[0064] Optionally, in one embodiment of the stacked filter 100 provided in this application, the drive member 41 may be a cylinder or a motor, etc., and the connector 42 includes a first main body 421, a second main body 422, an elbow 423, a connecting flange 424, and a diagonal brace 425.

[0065] The two ends of the elbow 423 are connected to the first main body 421 and the second main body 422 respectively. One end of the second main body 422 is connected to the drive member 41 through the connecting flange 424, and one end of the first main body 421 is connected to the hook 43. The two ends of the diagonal brace 425 are connected to the first main body 421 and the second main body 422 respectively.

[0066] The stacked filter 100 provided in this application, by providing a first main body 421, a second main body 422, an elbow 423, a connecting flange 424, and a diagonal brace 425, can improve the structural strength and stability of the connector 42 and prevent shaking or other phenomena when driving the stacked filter assembly 20 and the linkage assembly 30 to move.

[0067] Preferably, in one embodiment of the stacked filter 100 provided in this application, the stacked filter 100 further includes a sealing element 50. The sealing element 50 is disposed between the upper cover 12 and the cylinder 11 to seal the gap between the upper cover 12 and the cylinder 11.

[0068] Optionally, in this embodiment, the seal 50 can be an O-ring or sealant, etc., and this application does not limit it.
