Abstract
The utility model discloses a kind of canvas press cloth, it comprises filter cloth, elastic edge, lug boss position protective layer, edge bandage, feeding mouth protective layer; It is cotton layer that filter cloth comprises ground floor, is connected with non-woven fabrics filter core layer, connects adhesive phase below filter core layer, connect superfine fibre layer below adhesive phase below this cotton layer, and adhesive phase is polyolefin or polyolefin derivative thing or improved polyalkene; The maximum extending 5cm of elastic edge, elastic edge is positioned at filter cloth surrounding sealing the margin place, and elastic edge material is rubber; Boss protective layer and feeding mouth protective layer are the filter clothes after brush coating.The utility model structure is simple, and filtering accuracy is high, and intensity is high, not fragile, solves the problem that the filter cloth sealing the margin that causes when plate and frame filter press compresses filter plate is easily torn, and extends filter cloth service life.
Description
Technical field
The utility model relates to a kind of canvas press cloth.
Background technology
At present, known canvas press cloth generally adopts the single or multiple lift structure of cotton or fiber cloth, typical multilayer canvas press cloth is composited by the pure cotton non-woven fabrics filter core layer of the degreasing bleached cotton cloth layer on upper strata, the degreasing bleached cotton cloth layer of lower floor and centre, the canvas press cloth of this sandwich construction, still have that filtering ability is more weak, intensity is low, flimsy defect, and filtering accuracy can not reach high requirement.And filter cloth naturally hangs down and rides over filter plate surface, when filter press compresses filter plate, filter cloth can produce distortion, if now the deflection of filter cloth is too little, just easily tears.And the technical requirement of filter press to filter cloth is more hard better, more not yielding better, because it is most effective when rigid filter media to filter slip, but more the filter medium of rigidity is more unable to undergo to tear.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of canvas press cloth.
For achieving the above object, the technical solution adopted in the utility model is: it comprises filter cloth, elastic edge, lug boss position protective layer, edge bandage, feeding mouth protective layer; It is cotton layer that filter cloth comprises ground floor, is connected with non-woven fabrics filter core layer, connects adhesive phase below filter core layer, connect superfine fibre layer below adhesive phase below this cotton layer, and adhesive phase is polyolefin or polyolefin derivative thing or improved polyalkene; The maximum extending 5cm of elastic edge, elastic edge is positioned at filter cloth surrounding sealing the margin place, and elastic edge material is rubber; Boss protective layer and feeding mouth protective layer are the filter clothes after brush coating.
The utility model has following beneficial effect: the utility model structure is simple, filtering ability is strong, filtering accuracy is high, intensity is high, not fragile again, solves the problem of filter cloth marginal laceration when filter press compresses, and extends filter cloth service life.
