Bħala l-"ċentru ta' kmand" ta' filtru tat-tamburu ta' vakwu, id-disk ta' distribuzzjoni tal-gass huwa mu fisslti-channel disc valve. Its core mission is to coordinate with the rotation of the drum and accurately deliver the two "power commands"—vacuum from the vacuum box and compressed air—to the filter chamber that is currently at the responsive workstation. This precise gas distribution process relies on the airtight cooperation between the distributor head (which rotates synchronously with the drum) and the surface of the fixed gas distribution disc. This ensures the continuous and cyclic operation of the four stages: filtration, washing, dewatering, and discharging.

Funzjonijiet Ewlenin: Bidla ta' Triq tal-Gass u Kontroll ta' Proċess

Bħala l-qalba ta' kontroll tal-filtru tat-tamburu ta' vakwu, id-disk ta' distribuzzjoni tal-gass jiżgura kull filter chamber on the drum sequentially performs the following operations through its internally precise gas path zoning:

Żona ta' Filtrazzjoni: Id-disk ta' distribuzzjoni tal-gass jikkonnetti mal-pipeline ta' vakwu, u jippermetti li l-filtrat ikun suctioned in. Solid particles are adsorbed on the drum surface and form green tea cakes.

Washing Zone: Jgħidilill-likwidu tat-tnixxija jgħaddi b'mod uniformi mis-saff tal-kejk tal-filtru, u jibbesaway the waste liquid after the washing process is completed.

Dewatering Zone: Grad għoli ta' vakwu jinżamm kontinwament biex jitneħħa b'mod fond il-likwidu mħallat mill filter cake, achieving further drying.

Discharging Zone: It-triq tal-gass tinbidel għal arja kkumpressata, u l-fluss ta' l-arja jintuża biex jinflaħ il-filter cake off the filter cloth. A scraper needs to be used in conjunction to ensure clean discharging.

Karatteristiċi Strutturali Ewlenin

Id-disinn strutturali tad-disk ta' distribuzzjoni tal-gass huwa assoċjat direttament mal-filtru tiegħuation efficiency and operational stability, with its main features reflected in three aspects:

Clear Zoning: Il-wiċć tad-disk huwa maqsum b'mod preċiż f'żoni multipli indipendenti ta' triq tal-gass f'forma ta' mergħas, which correspond to process stages such as filtration, washing, dewatering, and discharging respectively. This ensures accurate and orderly gas path switching during each stage.

Tight Sealing: Siġilli ta' preċiżjoni għolja jintużaw bejn id-disk u r-ras tad-distributur rotanti, effettivamentively preventing cross-talk between the vacuum and compressed air circuits. This guarantees the stability of the system’s vacuum degree and the smoothness of the discharging action.

Id-disk ta' distribuzzjoni tal-gass huwa l-aktar magħmul minn azzar inox, ligi speċjali, jew plastik ta' saħħa għolja-strength cast iron with surface hardening treatment. It exhibits excellent wear resistance and corrosion resistance, enabling it to withstand long-term rotational friction and erosion under complex working conditions.
