Technical field
The utility model relates to filter, relates in particular to a kind of PUR double pressure filter.
Background technology
PUR is a kind of plastic adhesive, and in certain temperature range, its physical state changes with temperature change, and chemical characteristic is constant, and it is nonpoisonous and tasteless, belongs to environmental-protecting chemical product.
The first step in PUR particle manufacture process be by PUR proportioning well after, clamp-on and in grain forming mould, carry out granulation processing by extruder, high-quality PUR is not allow to occur granule foreign, thereby before particle moulding, needs PUR to carry out filtration treatment.
Prior art is retrieved, is had following prior art:
Patent 1:
Applicant: Jin Yan marine organisms Science and Technology Co., Ltd. of Fujian Province, application number: 201220547492.2, the applying date: 2012-10-24, patent name is that one is carried glue filter, containing organic frame, oscillator, screen frame, screen frame is fixed on frame top by spring support, screen frame top is charge door, and screen frame upper left-hand is provided with sludge outlet, and right side, screen frame bottom is provided with glue outlet, wherein screen cloth is connected with sludge outlet bottom surface, and oscillator and screen frame are integral type structure.The utility model is simple in structure, the screen cloth of integral type and the combination of oscillator, make to be difficult for gathering materials in the isolated by filtration of glue, treating capacity is large and volume is little, screen cloth is connected and keeps 30 ° of angles with sludge outlet bottom, both guaranteed that glue was difficult for directly discharging from sludge outlet, and facilitated again solid impurity to discharge.
Patent 2:
Applicant: Wenzhou Yu Feng chemical fibre equipment Co., Ltd, application number: 201220269310.X, the applying date: 2012-06-08, the utility model discloses a kind of viscose filter, comprise cavity, cylinder mould, viscose glue entrance, viscose glue outlet and end cap, described cylinder mould is positioned at cavity, and on cylinder mould, be provided with screen pack, described cavity is separated into inner chamber and exocoel, described viscose glue entrance communicates with described inner chamber, described viscose glue outlet communicates with described exocoel, it is characterized in that being provided with and thering is external screw-thread the central tube with cavity in described cylinder mould, described central tube is provided with the first through hole, on described central tube, cover has sleeve pipe, two ends at described sleeve pipe are provided with piston, described piston contacts with described cylinder mould inwall, described sleeve pipe is provided with the second through hole, described the second through hole communicates with the first through hole, on described end cap, be provided with screwed pipe, described screwed pipe is threaded with described central tube, described screwed pipe and transmission mechanism are in transmission connection.This structure of the present utility model, can realize and not shut down anti-cleaning automatically, has reached the object of continuous filtration.Simple to operate, automaticity is high, and labour intensity is low.
Existing patented technology scheme has different technical schemes from the present invention above, thereby above prior art can not destroy the novelty of this patent, and combination each other can not destroy the creativeness of this patent.
Utility model content
The purpose of this utility model be the next link that finishes in PUR proportioning by PUR is carried out to filtration treatment, thereby obtain high-quality PUR particle.
For realizing above object, the technical solution adopted in the utility model: a kind of PUR double pressure filter, is characterized in that it comprises sebific duct (1), bearing plate (2), warming plate (3), guide tank (4), resistance wire (5), macropore filter (6), hole filters (7); Described macropore filter (6) is arranged on installing plate (13) above with hole filters (7), and macropore filter (6) is arranged on hole filters (7) inside, between installing plate (13) and bearing plate (2), is provided with Connection Block (9); Above-described resistance wire (5) is arranged between warming plate (3) and guide tank (4); Going out sebific duct (1), bearing plate (2), warming plate (3), guide tank is bolted between (4); On described bearing plate (2), be provided with fluid hole (21).
Under better performance, described guide tank (4) is provided with slope (41).
The beneficial effects of the utility model: described macropore filter and hole filters are arranged on installing plate, macropore filter is arranged on hole filters inside, from but filter process, first in macropore filter, solid impurity particle filtering larger volume is fallen, then in hole filters, little solid impurity particle filtering is fallen, form a kind of staged, improve filter efficiency.
Filter is after shutdown; part PUR is in filter interior cooled and solidified; while again start, impact is normal filters; the critical function that resistance wire has is exactly preheating before again starting shooting; make inner residual PUR softening; thereby strengthen the result of use while again start, the service life of having improved filter.
The next link that the utility model finishes in PUR proportioning is by PUR is carried out to filtration treatment, thereby obtains high-quality PUR particle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model fundamental diagram in the situation that being equipped with force pipe.
The specific embodiment
As shown in Figure 1, structure annexation of the present utility model is: a kind of PUR double pressure filter comprises sebific duct 1, bearing plate 2, warming plate 3, guide tank 4, resistance wire 5, macropore filter 6, hole filters 7; Described macropore filter 6 is arranged on installing plate 13 with hole filters 7, and macropore filter 6 is arranged on hole filters 7 inside, between installing plate 13 and bearing plate 2, is provided with Connection Block 9; Above-described resistance wire 5 is arranged between warming plate 3 and guide tank 4, and described guide tank 4 is provided with slope 41; Go out between sebific duct 1, bearing plate 2, warming plate 3, guide tank 4 and be bolted; On described bearing plate 2, be provided with fluid hole 21.
