Uas lub "command center" ntawm tshuab npog drum vacuum, cov cov pa qhia cuab yeej yog ib lub ruaj khov multi-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.

Cov Hauj Lwm Tseem Ceeb: Gas Txoj Kev Hloov Thiab Kev Tswj Txheej Txheem

Uas lub tswj tseem ceeb ntawm tshuab npog drum vacuum, cov pa qhia cuab yeej ntseeg tau txhualter chamber on the drum sequentially performs the following operations through its internally precise gas path zoning:

Cheeb Tsam Npog: Cov pa qhia cuab yeej txuas nrog vacuum paj ncauj, pab cov kua npog los suctioned in. Solid particles are adsorbed on the drum surface and form green tea cakes.

Washing Zone: Nws qhia cov kua ntxuav hla sib xws ntawm cov khoom nrig theem, thiab nyobaway the waste liquid after the washing process is completed.

Dewatering Zone: Vacuum siab ruaj khov tsis nres kom muab cov kua sib xyaw muab tawm tob ntawm cov filter cake, achieving further drying.

Discharging Zone: Cov pa txoj kev hloov mus rau compressed cua, thiab cov cua siv los qw cov qhuav filter cake off the filter cloth. A scraper needs to be used in conjunction to ensure clean discharging.

Cov Kab Nrig Yam Ntxim Tseem Ceeb

Cov kab nrig kev tsim ntawm cov pa qhia cuab yeej cuam tshuam ncaj qha nrog nws cov npogation efficiency and operational stability, with its main features reflected in three aspects:

Clear Zoning: Cov daim ntsej muag faib ncaj ncees mus rau ntau lub fan-shaped gas txoj kev cheeb tsams, 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: Cov seals ncaj ncees siab siv ntawm cov daim thiab tig distributor head, ua hauj lwmively 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.

Khoom Siv Tiv Thaiv Kev Hnav: Cov pa qhia cuab yeej feem ntau ua los ntawm stainless hlau, cov alloys tshwj xeeb, lossis siab-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.
