Abstract
Provided is a production system for a novel filtering material non-woven fabric. The system comprises a drying tower, a screw extruder, a precision filter, a spinning cabinet, a tensioning roller, a draw roll, an air-flow stretching system, a web former, heat-setting machine, a cooling roller, and a winding roller. The discharge port of the drying tower is connected with the feed port of the screw extruder. The discharge port of the screw extruder is connected with the precision filter. The precision filter is above the spinning cabinet. The tensioning roller, the draw roll, the air-flow stretching system, and the web former are below the spinning cabinet from top to bottom in sequence. In the system, PET which is melted and filtered enters the spinning cabinet and respectively passes through a first spinneret plate and a second spinneret plate, and a fiber web formed by the PET, manufactured by a spinning device, is directly sent to the heat-setting machine to solidify. The fiber web is not influenced by external forces, and a product is fluffy, and product gas permeability is greatly improved, so the manufactured novel filtering material non-woven fabric can be preferably used in a low pressure difference filtering device. Therefore, a problem that production of a novel filtering material non-woven fabric is difficulty is solved.

Detailed description of the invention
A kind of nonwoven production system of novel filter material, comprise drying tower 1, screw extruder 2, accurate filter 3, manifold 4, tightening roller 5, draw roll 6, air drawing system 7, lapper 8, heat setting machine 9, chill roll 10 and winding roller 11, the discharging opening of drying tower 1 is connected with the charging aperture of screw extruder 2, the discharging opening of screw extruder 2 connects accurate filter 3, accurate filter 3 is positioned at manifold 4 tops, tightening roller 5, draw roll 6, air drawing system 7 and lapper 8 are positioned at manifold 4 belows from top to bottom successively, heat setting machine 9, chill roll 10 and winding roller 11 are positioned at lapper 8 fronts successively, interior the first spinneret 12 and the second spinneret 13 of arranging respectively of manifold 4, on the first spinneret 12, evenly offer several the first connecting holes 15, on the second spinneret 13, evenly offer several the second connecting holes 17, first spinneret 12 one end connect the first gear 18, second spinneret 13 one end connect the second gear 19, between the first gear 18 and the second gear 19, driving gear 20 and driven gear 21 are set, driving gear 20 is connected with actuating unit, driving gear 20 engages with the first gear 18 and driven gear 21 respectively, driven gear 21 engages with the second gear 19, angle α between the first spinneret 12 and the second spinneret 13 is 0 °-120 °, the inclination angle beta of the first spinneret 12 is 0 °-60 °. job step of the present invention is as follows, and wet PET section is removed to the moisture in section through pre-crystallized and drying tower 1, improves degree of crystallinity and the softening point of PET section. dried PET section, enters screw extruder 2 and melts, and enters manifold 4, then spray elongated filament by the first spinneret 12 and the second spinneret 13 respectively by accurate filter 3 after filtering. for novel filter material nonwoven is better applicable on low voltage difference filter plant, angle between the first spinneret 12 and the second spinneret 13 can be carried out adjusted in concert by driving gear 20, this structure has improved product uniformity and tensile strength, dwindles PRODUCTS FIELD to strength ratio. the as-spun fibre silk that the first spinneret 12 and the second spinneret 13 spray first stretched roller 6 carries out mechanical stretching, more again stretches by air drawing system 7, and by air-flow, filament is layered on lapper 8 uniformly. this structure can fully stretch to fiber, better controls the fineness of fiber, improves dawn number and the brute force of fiber, ensures interfibrous spacing, has improved product gas permeability and intensity. the fibre web of completing is sent into heat setting machine 9, and the fibre web rear portion filament that is heated melts with adjacent filament adhered to one anotherly, and fibre web is consolidated at the formation novel filter material nonwoven of lower the temperature through chill roll 10, and on winding roller 11 rolling. this structure has improved the power of tearing of product, has greatly increased product gas permeability, makes product have fluffy sense, thereby has increased product thickness.
The first described connecting hole 15 upper ends are offered the first bellmouth 14, the second connecting hole 17 upper ends and are offered the second bellmouth 16. This structure has increased filament and has entered connecting hole, has improved product uniformity and tensile strength, dwindles PRODUCTS FIELD to strength ratio, and novel filter material nonwoven is better applicable on low voltage difference filter plant.
Through applicant's experiment repeatedly and contrast, the optimized angle of the angle α between described the first spinneret 12 and the second spinneret 13 is 90 °, and the optimized angle of the inclination angle beta of the first spinneret 12 is 45 °. This set can improve product uniformity and tensile strength, dwindles PRODUCTS FIELD to strength ratio, and novel filter material nonwoven is better applicable on low voltage difference filter plant.
