Abstract
The utility model relates to a filter device, in particular to a melt filter device in the chemical fiber industry. The melt filter device mainly includes a filter, heat exchangers and three-way valves; the filter mainly comprises filtration chambers and filter elements, the filter elements are arranged in the filtration chambers, the heat exchangers are arranged on the peripheries of the filtration chambers, and jackets of the heat exchangers are filled with liquid media; the filter is further provided with a feed port and a discharge port, the feed port is connected with a feed pipeline, one three-way valve is arranged on the feed pipeline, the discharge port is connected with a discharge pipeline, and the other three-way valve is arranged on the discharge pipeline. The melt filter device is ingenious in conception, and the filter elements with the filter fineness of 15 microns are adopted behind a final polycondensation reactor, so that mechanical impurity particles with the diameters greater than 15-20 microns in melt are filtered out. The melt filter device also has an effect of homogenizing the melt, therefore, the quality of the melt is improved, and fractures of the melt in the production process are reduced.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to the melt filter in chemical fibre industry.
Background technology
In the melting high-speed spinning forming process, improve spinning quality, reduce the spinning cost, the filter device that is absolutely necessary, because spinning strand diameter is very thin, spinneret orifice is very little, does not allow in melt to be mixed with any impurity or gel particles, therefore improve the purity of melt, is that one of key with the finished silk quality is normally carried out in the assurance spinning.So high speed spinning must install prefilter additional,, to improve the purity of melt, reduce the burden of filter course in filament spinning component, extend life cycle, the waste silk that minimizing produces because of the transposing filament spinning component has improved like this quality and has reduced again cost.Must choose suitable filter at device in prefilter, be difficult for stopping up, withstand voltage, heatproof and corrosion resistant characteristics, and will adapt to the continuous spinning requirement.
The general use of existing filter core be that filtering accuracy is that the filter core of 20um or 25um uses, in melt, diameter does not fall greater than the mechanical admixture particulate filter of 15-20um, and melt is not carried out corresponding homogenize in the process of filtering, cause melt quality to descend.
The utility model content
The utility model has designed a kind of melt filter in order to address the above problem, its purpose is: adopting filtering accuracy after terminal polymerization kettle is the filter core of 15um, filter out in melt diameter greater than the mechanical admixture particle of 15-20um, and have the effect of homogenize melt concurrently, improve melt quality, reduce in production process and break end.
The utility model technical solution:
A kind of melt filter, mainly comprise: filter, heat exchanger and triple valve, it is characterized in that: described filter mainly comprises filter chamber and filter core, described filter core is arranged on inside, filter chamber, be arranged with heat exchanger outside filter chamber, fill liquid media in the heat exchanger chuck, described filter also is provided with charging aperture and discharging opening, described charging aperture is connected with feed pipe, be provided with triple valve on described feed pipe, described discharging opening is connected with discharge pipe, also is provided with triple valve on described discharge pipe.
Described filter chamber is made by stainless steel integrated, adopts jacketed type exchanger outside filter chamber, and the whole welding type bottom, be used for heat is delivered to filter chamber from heating agent.
Described filter core mainly comprises core cylinder and metal knitted filter screen, and described core cylinder arranges the metal knitted filter screen of at least one layer outward.
The beneficial effects of the utility model:
The utility model is skillfully constructed, and adopting filtering accuracy after terminal polymerization kettle is the filter core of 15um, filters out in melt diameter greater than the mechanical admixture particle of 15-20um, and has the effect of homogenize melt concurrently, improves melt quality, reduces in production process and breaks end.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, filter mainly comprises filter chamber 4 and filter core 1, filter core is arranged on inside, filter chamber, be arranged with heat exchanger 2 outside filter chamber, fill liquid media in the heat exchanger chuck, filter also is provided with charging aperture and discharging opening, charging aperture is connected with feed pipe, be provided with triple valve 3 on feed pipe, discharging opening is connected with discharge pipe, also is provided with triple valve on discharge pipe.Filter chamber is made by stainless steel integrated, adopts jacketed type exchanger outside filter chamber, and band whole welding type bottom, be used for heat is delivered to filter chamber from heating agent.Filter core 1 mainly comprises core cylinder 5 and metal knitted filter screen 6, and the core cylinder arranges the metal knitted filter screen 6 of at least one layer outward.
The specific works process:
adopt fondant filter to carry out impurity screening to melt after terminal polymerization kettle, melt from feed pipe through triple valve 3, charging aperture enters filter chamber 4, triple valve 3 can switch according to pressure differential size before and after filter, be used alternatingly filter chamber 4, to guarantee the continuity of melt filtration, 4 inside, filter chamber arrange some filter cores 1, adopting filtering accuracy is the filter core of 15um, filter core 1 is made supporter by core cylinder 5 with holes, skin arranges the metal knitted filter screen 6 of single or multiple lift, the filter core 1 that switches is after clean, damage as nothing, can reuse, the shell of filter chamber 4 is made by stainless steel integrated, outside and heat exchanger 2 connects into an integral body, heat exchanger 2 is delivered to filter chamber 4 to heat, melt is heated, more be conducive to the filtration of melt, the melt that has filtered from filter chamber 4 discharging flow out from discharge pipe through another triple valve 3, enter next process.
To sum up, the utility model produces a desired effect.
