[0002] In the fields of purification of multi-pollutants in glass furnaces, coking furnaces, industrial boilers, waste incineration and other flue gases, ceramic fiber filter cartridges are a widely used type of filter, which uses rigid microporous materials as filter elements. Compared with traditional granular filter materials, ceramic fiber filter cartridges have a larger specific surface area of fiber filter materials, have a larger interfacial adsorption and can intercept suspended matter, and have good filtration effects; compared with traditional filter materials such as cloth bags, ceramic fiber filter cartridges can be used in high-temperature or even ultra-high-temperature environments; compared with porous ceramics and metal filter materials, ceramic fiber filter cartridges do not require sintering, have low resistance and save energy consumption, and have good chemical stability and thermal shock resistance.

[0029] The present utility model provides a support assembly for forming the flange end of a ceramic fiber filter cartridge, which is used to support the support assembly for forming the flange end of a ceramic fiber filter cartridge. By setting a suction filter plate and a device connecting to the suction filter vacuum, the strength of the flange end of the ceramic fiber filter cartridge can be greatly increased, the failure rate can be reduced, the connection of the ceramic fiber filter cartridge can be ensured to be stable, and the service life can be increased.

[0030] As Figure 1 shown, in this embodiment, the support assembly includes a support base 610 which has a through hole 611 for installing a shaft part for rotary centrifugal cloth feeding or a bearing for supporting a shaft part.

[0031] One side of the support base 610 has a suction filtration orifice plate 620 which serves as a forming template for the flange end of the ceramic fiber filter cartridge. As Figure 2 shown, the suction filtration orifice plate 620 has a plurality of filter holes for allowing water and gas to pass through. The support base 610 has at least one channel 612 communicating with the suction filtration orifice plate 620, and the support base 610 also has a suction filtration interface 613 installed at the other end of the channel 612.

[0032] In the above embodiment, the support base 610 of the support assembly is fixedly arranged and mainly used for supporting a shaft-type part for cloth feeding. The shaft-type part can be as Figure 3 shown. The shaft-type part can include a mounting shaft section 510 and a cloth feeding shaft section 520, and a flow channel 501 for allowing slurry to flow is arranged inside. The mounting shaft section 510 is used for connecting with a device for driving its rotation, and one end of the mounting shaft section 510 is provided with a slurry feeding interface 511. The slurry feeding interface 511 of the flow channel 501 can be connected with a feeding part to provide a continuous supply of slurry, and the other end of the flow channel 501 can be blocked so that the slurry can only flow out from the following cloth holes 502. In the embodiment of the present utility model, the support base 610 of the support assembly is installed at the shoulder position at the junction of the mounting shaft section 510 and the cloth feeding shaft section 520 for supporting the rotary centrifugal motion of the shaft-type part.

[0033] As Figure 4 shown, it is a structural schematic diagram of the above-mentioned ceramic fiber filter cartridge. The ceramic fiber filter cartridge includes a body part 11, a flange end 12 and a plug end 13. The support base 610 of the support assembly is used for covering the flange end of the ceramic fiber filter cartridge and can also be regarded as belonging to the forming template of the flange end; the support base 610 of the support assembly is provided with a suction filtration orifice plate 620 which can be connected with a vacuum pumping device for suction filtering vacuum during the forming process of the flange end of the ceramic fiber filter cartridge to quickly pump away water and gas, so that the flange end is quickly formed; and by increasing the vacuum degree, the density of the flange end is increased, so that the strength of the flange end of the formed ceramic fiber filter cartridge is increased.

[0034] In some embodiments, there are two or more channels 612 in the support base 610 that communicate with the suction filtration orifice plate 620. The other end of each channel 612 is provided with a suction filtration interface 613, which is used to connect to the pipeline of a vacuum pumping device. Preferably, the suction filtration interface 613 is located at one end of the support base 610 opposite to the suction filtration orifice plate 620. By providing two or more channels 612, the pipelines of multiple vacuum pumping devices can be connected, which can increase the suction filtration vacuum degree or enable more precise control of the vacuum degree through functional valves on the pipeline, so as to form the flange end.

[0035] In some embodiments, as Figure 1 shown, a pair of bearings 631 for supporting shaft-like parts are installed in the through hole 611 of the support base 610. Preferably, a bearing end cover 632 is installed on the end face of the support base 610 close to the bearing 631. In this embodiment, one side of the bearing is fixed by the annular table surface of the through hole 611, and the other side of the bearing is fixed by the additional bearing end cover 632. In this embodiment, by providing bearings for supporting shaft-like parts, the friction of the shaft-type parts can be reduced, making it have a smaller rotational eccentricity error and more uniform cloth distribution.

[0036] In some embodiments, as Figure 1 shown, the support base 610 is provided with a sealing structure 614 on the end face where the suction filtration orifice plate 620 is located to seal the forming space of the ceramic fiber filter cartridge, preventing external gas from entering and internal slurry from leaking.

[0037] In the above embodiments, the forming of the ceramic fiber filter cartridge also requires an external mold. The inner cavity contour of the external mold is the outer contour of the ceramic fiber filter cartridge, and the support base 610 is used to block the flange end of the ceramic fiber filter cartridge. Since the support base and the external mold are in a butt-jointed structure, a sealing structure needs to be provided on their butt-jointed end faces to prevent the loss of slurry in the inner cavity or the entry of external air, which may affect the forming process of the ceramic fiber filter cartridge.

[0038] Preferably, the sealing structure 614 can be an inwardly recessed annular sealing groove or an annular rubber ring. When the sealing structure 614 is an inwardly recessed annular sealing groove, correspondingly, the butt-jointed end face of the external mold has a protruding annular sealing structure to form a labyrinth seal.

[0039] In some embodiments, as Figure 1 shown, the channel 612 is a bent or inclined structure to avoid the installation space of the bearing 631.
