Detailed Implementation

[0026] 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.

[0027] 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.

[0028] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely 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.

[0029] like Figures 1 to 5 As shown in the figure, an online backflushing filter washing and drying machine chassis assembly according to an embodiment of the present invention includes a filter plate 1, a guide plate 2, and a base 3 arranged from top to bottom.

[0030] The filter plate 1 and the guide plate 2 have a medium channel 202 for the medium to pass through, and the guide plate 2 has a first connecting hole 201 at its center.

[0031] It also includes a mother liquor inlet 4, a first control valve 5, and a second control valve 6. The mother liquor inlet 4 has a first port 41, a mother liquor outlet 42, and a backflush inlet 43.

[0032] The first port 41 is connected to the first connection hole 201 and communicates with the medium channel 202. The mother liquor outlet 42 is connected to the first control valve 5. The first port 41 is connected to the first connection hole 201 and communicates with the medium channel 202. The mother liquor outlet 42 is connected to the first control valve 5 and controls whether the liquid leaves the mother liquor connector 4 through the mother liquor outlet 42. The backflush inlet 43 is connected to the second control valve 6 and controls whether the gas enters the mother liquor connector 4 through the backflush inlet 43.

[0033] With this setup, when in use, the second control valve is closed and the first control valve is opened. The mother liquor passing through the filter plate and media channel can be recovered by leaving the mother liquor connector through the mother liquor outlet. When the first control valve is closed and the second control valve is opened, the backflushing gas can reach the media channel along the mother liquor connector and disperse below the filter plate. Then, it can promote the complete fusion of the material and the cleaning solvent through the filter plate. The structure is simplified, and the effects of unclogging the filter plate and thoroughly cleaning the material are achieved at the same time.

[0034] The flow guide plate 2 includes a connecting chassis 21 and an annular baffle assembly connected to the upper end of the connecting chassis 21.

[0035] The annular baffle assembly includes a first annular baffle 22 surrounding the first connecting hole 201 and several second annular baffles 23 surrounding the first annular baffle 22 and arranged from the inside out. Each annular baffle is provided with a flow guide 24, and a baffle 25 is provided between adjacent annular baffles. The adjacent flow guides 24 are located on both sides of the baffle 25.

[0036] With this setup, the backflushing gas is evenly distributed to the lower end face of the filter plate along the path formed by each annular baffle, further improving the fusion effect of the material and the cleaning solvent, and enhancing the sufficiency of the filter plate in clearing and cleaning the material.

[0037] The upper end of the first annular partition 22 is connected to a barrier plate 26 that closes off its upper port.

[0038] With this configuration, the backflush gas can only pass through the guide port of the first annular baffle and will not diffuse directly from its upper port to the top of the filter plate, thus improving the uniform distribution of the backflush gas on the lower end face of the filter plate.

[0039] There is a gap between the upper end of the barrier plate 26 and the lower end of the filter plate 1.

[0040] With this setting, the backflush gas can reach the center of the filter plate through the gap between the two, further improving the uniform distribution of the backflush gas on the lower end face of the filter plate.

[0041] The upper end of each second annular partition 23 abuts against the lower end of the filter plate 1.

[0042] With this setting, the backflush gas can only pass through the guide port of the second annular baffle and will not diffuse directly from its upper end to the top of the filter plate, further improving the uniform distribution of the backflush gas on the lower end face of the filter plate.

[0043] Each annular baffle is set concentrically.

[0044] This setting improves the symmetry of backflush gas diffusion.

[0045] The upper surface of the connecting chassis 21 slopes downward from the outside to the center to form a guide slope 211.

[0046] With this setup, the mother liquor tends to converge towards the center and is less likely to accumulate on the filter plate.

[0047] It also includes a filter plate bracket 7, wherein the upper inner circumference of the filter plate bracket 7 is provided with a first positioning ring groove 71 that is adapted to the shape of the filter plate 1, and the filter plate 1 is connected in the first positioning ring groove 71;

[0048] The filter plate bracket 7 has a second positioning ring groove 72 on the inner circumference of its lower end that matches the shape of the outer circumference of the upper end of the base 3, and the filter plate bracket 7 is connected to the base 3.

[0049] This design improves the ease of disassembly and assembly of the chassis components, while also enhancing the positioning accuracy during installation.

[0050] 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.
