Description
Technical field
The present invention relates to the air distributing device that a kind of vacuum filter in vacuum filtration machine equipment is used.
Background technology
The air distributing device that vacuum filter is used, the control head using while distributing source of the gas in vacuum filtration machine equipment specifically, can make vacuum filter be divided into Cheng Bing district, dry section, dead band, discharge zone and ，Ge district, renewing zone relatively airtight by distribution head, finally reach the effect of material thing dehydration.
At present, in the factory technics flow process dewatering periods such as ore dressing plant, coal washery, pulp mill, sewage treatment plant, often adopt thickener to add the dewatering process of vacuum filter; Because processed raw meal particle size is more and more thinner, the difficulty that reaches dewatering process index is increasing.The material concentration that general thickener gets off is only at 40%-60%, and current factory need to consider the needs of environmental protection or back segment flow process, and the final water content requirement of material thing has been reached to even lower 15% below, like this to the requirement of filter with regard to height very.
Traditional vacuum filter can reach below 11% at processing thicker material (200 orders account for 80%) moisture; And at present, need dehydrated thin material (325 orders account for 90%) more and more, traditional vacuum filter cannot be controlled the formation thickness of filter cake, so, because material thing is meticulous, the barrier film water, soakage water, the pore water that in thicker filter cake, are mingled with are more, and vacuum draft is difficult to slough these moisture, so be controlled to thinner filter cake, are to slough more juicy key.
The too high meeting of moisture of material thing causes larger economic loss to back segment flow process, to such an extent as to there are at present a lot of methods to remove to reduce the final moisture of material, wherein by vacuum filter, dewatering is most cost-saving and effect mode preferably, except vacuum dehydration, also have pressurizing and dehydrating and drying and dehydrating, financial cost is but 2-3 times of vacuum dehydration.Therefore, develop the air distributing device that a kind of vacuum filter uses is new problem anxious to be resolved always.
Summary of the invention
