Description
Technical field
The utility model relates to a kind of for nylon polymerization device underwater pelletizer pelletizing water filtering device.
Background technology
Germany's Lurgi Zimmer company's polyamide fibre (PA6) polymerization technique is the typical process of the civilian silk of the production PA6 section that generally adopts of our times.Its main feature: adopt the continuous polymerization of large-scale VK pipe, 260 DEG C of polymerization temperatures, time 20h, residual monomer and oligomer in hot water counter-current extraction section, stream of nitrogen gas are dry, the control of DCS distributing system, MONOMER RECOVERY adopts the continuous three-effect evaporation and condensation of extraction water, is interrupted distilled and concentrated solution technique.There is production serialization, output is high, quality good, floor space is few feature.
Germany Lurgi Zimmer company technique PA6 granulation adopts underwater pelletizer; PA6 melt stretching and granulation under water; pelletizing is sent to subsequent processing through centrifugal drying; the water of centrifugal drying recycles after circulating after chilled water is cooling; because contain short grained section powder in water; must remove in time, otherwise accumulation will cause centrifugation normally to move in system.
In existing product, pelletizing hydromining filters with box filter, the box filter existing problems that use at present:
1, will close after box filter, with the direct flushing filtering net of pure water and water is drained entirely, this method can not thoroughly be cleaned filter screen, and can waste a large amount of pure water;
If 2 need to thoroughly clean filter screen, each cleaning all will be taken out filter screen, then delivers to cleaning area giant and clean, but filter screen is heavier, and workload is very large;
If 3 reduce cleaning frequencies, along with increasing of filter residue, the resistance of filter screen can be increasing, can deform, breakage at the impact lower filter screen of pelletizing water;
4, the solid impurity that box filter does not filter out, first can in Pellets cooling water tank PCWT, deposit, because the Pellets cooling water tank PCWT cleaning frequency is very long, in tank, tend to deposit the impurity that one deck is very thick, long these monomers of time one or condensate impurity can go bad, and improve Filter Precision and can effectively alleviate the deposition of impurity in Pellets cooling water tank PCWT and rotten.
Utility model content
The problem that the utility model exists for above-mentioned prior art is made improvement; be that technical problem to be solved in the utility model is to provide one for nylon polymerization device underwater pelletizer pelletizing water filtering device; not only the cycle of operation is long; manual operation workload is little; and energy consumption is low, good product quality; device operates steadily reliably, can greatly extend the life cycle of drying system.
In order to solve the problems of the technologies described above; the technical solution of the utility model is: a kind of for nylon polymerization device underwater pelletizer pelletizing water filtering device; comprise columnar filter screen; described filter screen comprises metallic framework and covers the screen pack on skeleton; on one lateral wall of described filter screen, be provided with feed pipe; in described filter screen, be provided with not the swash plate with rotation, the top of described filter screen is provided with cleaning hose, described cleaning hose be arranged in swash plate directly over.
Further, by one, the motor with decelerator drives rotation to described filter screen.
Further, described swash plate is made up of a framework and the filter screen covering on framework.
Further, the bottom of described swash plate is provided with pelletizing collecting box, and described pelletizing collecting box is arranged in filter screen outside.
Further, the bottom of described filter screen is provided with water tank.
Compared with prior art, the utlity model has following beneficial effect:
1, adopt centrifugal separation method, efficiency is high, and equipment volume is little;
2, screen pack rotating speed is low, and system run all right is reliable;
3, screen pack is wire netting, screen pack long service life;
4, can procedure auto-control, periodic flushing;
5, regularly collect the particle washing down, impurity collecting box is movable, does not need to stop, and does not also affect the normal operation of pelleter.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Brief description of the drawings
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-filter screen, 2-feed pipe, 3-swash plate, 4-pelletizing collecting box, 5-cleaning hose, the motor of 6-with decelerator, 7-water tank.
Detailed description of the invention
Embodiment mono-: as shown in Figure 1; a kind of for nylon polymerization device underwater pelletizer pelletizing water filtering device; comprise columnar filter screen 1; described filter screen 1 comprises metallic framework and covers the screen pack on skeleton; on one lateral wall of described filter screen 1, be provided with feed pipe 2; in described filter screen 1, be provided with not the swash plate 3 with rotation, the top of described filter screen 1 is provided with cleaning hose 5, described cleaning hose 5 be arranged in swash plate 3 directly over.
In the present embodiment, by one, the motor 6 with decelerator drives rotation to described filter screen.
In the present embodiment, described swash plate 3 is made up of a framework and the filter screen covering on framework.
In the present embodiment, the bottom of described swash plate 3 is provided with pelletizing collecting box 4, and described pelletizing collecting box 4 is arranged in filter screen 1 outside.
In the present embodiment, the bottom of described filter screen 1 is provided with water tank 7.
In the utility model, pelletizing water enters motor from feed pipe 2 and drives in the filter screen 1 rotating; The particle that is greater than 100 μ m is tackled on screen pack, regularly by cleaning hose 5, filter screen 1 is cleaned, and the particle washing down from filter screen enters swash plate 3, and the filtering accuracy of this swash plate 3 is 100 microns.Swash plate 3 guarantees that the particle rinsing enters in dismountable pelletizing collecting box 4 automatically, and equipment can move continuously, as long as regularly take the material filtering down in pelletizing collecting box 4 away, does not need to stop, and does not also affect the normal operation of pelleter.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
