Acid And Alkali Resisting Polyester Mesh Screen For Sludge Dewatering

Acid And Alkali Resisting Polyester Mesh Screen For Sludge Dewatering

Brief Introduction:

Polyester Sludge Dehydration Fabrics is also called press-filter Fabrics which is mainly used for sludge dehydration, paper pulp and juice squeeze, mine smelting, mine tailing disposal and other pressure filtration industries.

They have the characteristics of good water permeability and non-revealed sludge, acid-resisting and alkali-resisting. Because of their designing structure, The sludge can be peel off easily from the filter cake, So the screen are easily cleaned and have a long working time.

Mainly matching with belt type filter press, vacuum rubber belt filter and horizontal vacuum belt filter.

Introduction of belt details:

Polyester press filter screen belt are characterized by high abrasion resistance and very good dimensional stability under machine load. The fabrics have a special construction so that the pressed liquid can drain and at the same time the filter cake is not pushed through the fabric. Individual fabrics differ in the speed of drainage, the size of the holes in the fabric, the smoothness of the surface for easy separation of the filter cake, the resistance to abrasion, etc.

Connections:

The edges of the sieve are smoothed by thermal sealing, reinforced in a width of about 4 cm with a two-component flexible adhesive. The sieves are connected into an endless strip by a demountable stainless steel (AISI 316) clipper joint. Another option for connecting the sieve into an endless strip is a woven non-separable joint, which has a longer service life than the clip joint, but can only be used on machines that allow the installation of an endless belt.

Filter screens are used as endless strips connected by a detachable or non-separable joint.

The edges of the filter screens are melted and reinforced with mechanically resistant flexible two-component adhesive. Triangular reinforcement of the joint at the edges of the sieve increases the mechanical resistance of the joint.

Advantages:

Very good drainage ability

Easy to clean

Universal sieve type for most industrial applications

Very high abrasion resistance

Long service life

For very abrasive sludges
