Abstract
The invention discloses a kind of paper grade (stock) double-layer filtering net, including screen pack body, screen pack body is made up of double-layer structure, respectively upper screen and lower screen, connected between upper screen and lower screen by supporter, the filter opening of upper screen is more than the filter opening of lower screen, and the outer wall of upper screen and lower screen scribbles anti-affine layer.The beneficial effects of the invention are as follows：It is simple in construction, using simple operation, by the way of double medium filtration, ink, resin and various adhesive can be effectively filtered out, extend service life, fixation between double-layer filtering net, improves stability, improves operating efficiency simultaneously, reduce cost, the setting of overcoat, can effectively prevent the blocking of filter opening, be easy to cleaning.
Description
Technical field
The present invention relates to a kind of screen pack, more particularly to a kind of paper grade (stock) double-layer filtering net.
Background technology
In paper industry typically using timber and wheat straw etc. as raw material, with the enhancing of environmental consciousness, people use back
The waste paper of receipts produces paper as raw material, still, and waste and old paper contains ink, resin and various sickers, ink, resin and each
Planting sicker has affinity, and the screen pack used at present is in filter process, and ink, resin and various sickers are easily to mistake
Filter net jam, the normal production of influence is cleaned, it is necessary to shut down, and is reduced production efficiency, is improved production cost, it is impossible to meets
The demand of industry.
Therefore, to solve the above problems, special provide a kind of new technical scheme.
The content of the invention
The present invention provides a kind of paper grade (stock) double-layer filtering net.
The technical solution adopted by the present invention is：
A kind of paper grade (stock) double-layer filtering net, including screen pack body, the screen pack body are made up of double-layer structure, be respectively on
Metafiltration net and lower screen, are connected, the filter opening of the upper screen between the upper screen and lower screen by supporter
More than the filter opening of lower screen, the outer wall of the upper screen and lower screen scribbles anti-affine layer.
Further, the copolymer for preventing that affine layer is tetrafluoroethene and hexafluoropropene.
Further, the supporter is fixed on the edge of upper screen and lower screen.
Further, the junction of the supporter and upper screen is provided with reinforcement.
Further, the junction of the supporter and lower screen is provided with reinforcement.
The beneficial effects of the invention are as follows：It is simple in construction,, can be effective by the way of double medium filtration using simple operation
Ink, resin and various adhesive are filtered out, service life is extended, while fixation between double-layer filtering net, is improved
Stability, improves operating efficiency, reduces cost, and the setting of overcoat can effectively prevent the blocking of filter opening, is easy to clear
It is clean.
Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
Wherein：1st, upper screen, 2, lower screen, 3, supporter, 4, filter opening, 5, reinforcement.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, does not constitute the restriction to protection scope of the present invention.
A kind of paper grade (stock) double-layer filtering net as shown in Figure 1, including screen pack body, screen pack body is by double-layer structure group
Into respectively upper screen 1 and lower screen 2 are connected, upper metafiltration between upper screen 1 and lower screen 2 by supporter 3
The filter opening 4 of net 1 is more than the filter opening 4 of lower screen 2, and the outer wall of upper screen 1 and lower screen 2 scribbles anti-affine layer, anti-parent
With the copolymer that layer is tetrafluoroethene and hexafluoropropene, supporter 3 is fixed on the edge of upper screen 1 and lower screen 2, supports
The junction of body 3 and upper screen 1 is provided with reinforcement 5, and supporter 3 and the junction of lower screen 2 are provided with reinforcement 5.
The beneficial effects of the invention are as follows：It is simple in construction,, can be effective by the way of double medium filtration using simple operation
Ink, resin and various adhesive are filtered out, service life is extended, while fixation between double-layer filtering net, is improved
Stability, improves operating efficiency, reduces cost, and the setting of overcoat can effectively prevent the blocking of filter opening, is easy to clear
It is clean.
The above described is only a preferred embodiment of the present invention, being not the limit for making any other form to the present invention
System, and any modification made according to technical spirit of the invention or equivalent variations, still fall within model claimed of the invention
Enclose.
