Abstract
The present invention discloses a nylon filtering belt for a belt filter press, which is characterized in that in the wet dedusting technology of converter steelmaking, the used filtering belt of the belt filter press is formed by braiding nylon threads by a netting machine according to warp threads and weft threads. The present invention has the advantages that the filtering belt which is made of the nylon threads and is braided by the netting machine has the advantages of acid resistance, alkali resistance, abrasion resistance, good flexibility, large extensibility and dehydration rate higher than a polyester filtering belt; a satin structure of the present invention has the advantages of flatness, good water permeability and no material leakage; the service life of the nylon filtering belt is as long as 4000 to 5000 hours.
Description
The present invention relates to the material of belt filter press strainer, particularly a kind of nylon strainer that is applied on the belt filter press.
At present; in the steel-making industry; open hearth steelmaking is replaced by pneumatic steelmaking gradually; in pneumatic steelmaking, generally all be to adopt wet dedusting, steel per ton will produce 3% dust; this part dust iron-holder can reach more than 58%; be that well raw material is reclaimed in ironmaking, reclaiming this part dust will have good economic benefits, also will play very important effect to the protection environment.China introduces by the CPF-5 of mine, Huaibei Machines Plant production with from Italy's introduction from Austria and changes the DYT-2000 belt filter press that shape is produced by Dandong water treatment research institute, reclaim iron content mud for the converter wet dedusting assurance is provided, but the material of the strainer of this belt filter press is made into for the polyester monofilament, this polyester strainer is short service life, and be 300-700 hour cover polyester strainer service life.
The purpose of this invention is to provide a kind of nylon strainer that is applied on the belt filter press, reach more than 4000 hours the service life of this nylon strainer.
Technical scheme of the present invention is to solve like this:
A kind of nylon strainer that is applied on the belt filter press is characterized in that: in the wet dedusting technology of pneumatic steelmaking, the strainer of the belt filter press of use is to form with warp, parallel braiding through netting machine with nylon wire.
Above-mentioned nylon strainer texture structure is chevron or broken satin weave structure.
Characteristics of the present invention are: the strainer that is made into through netting machine with nylon wire have acidproof, alkaline-resisting, wear-resisting, flexibility is good, ductility is big, dehydration rate is higher than the polyester strainer; It is smooth that wherein broken satin weave structure has wire side, good water permeability, the advantage of material ne-leakage; Can reach 4000-5000 hour the service life of this nylon strainer.
Embodiment 1:
The strainer of the belt filter press of embodiment 1 adopts nylon 6 wire drawings, is compiled into strainer through netting machine with warp, parallel, and its strainer structure is broken satin weave structure.
Embodiment 2:
The strainer of the belt filter press of embodiment 2 adopts nylon 66 wire drawings, is compiled into strainer through netting machine with warp, parallel, and its strainer structure is the chevron structure.
Embodiment 3:
The strainer of the belt filter press of embodiment 3 adopts nylon 14 wire drawings, is compiled into strainer through netting machine with warp, parallel, and its strainer structure is broken satin weave structure.
Following examples do not exemplify one by one; series of products with nylon; the strainer of making as nylon-7, nylon-8, nylon-9, nylon-10, nylon-11, PA-12, nylon-46, nylon-610, nylon-6 12, nylon-1010 etc.; the structure of signing an undertaking adopts broken satin weave structure or chevron structure, all belongs to the scope of this patent protection.
