Abstract
The utility model discloses a polyester melt filter. The polyester melt filter comprises a rack and two filtering chambers fixed on the rack, wherein a melt outlet is provided with a filtered melt sampling valve; a melt inlet is provided with a unfiltered melt sampling valve; the upper end of the rack is horizontally provided with a first heating medium outlet; the right end of the first heating medium outlet is provided with an exhaust opening; the lower end of the rack is horizontally provided with a first heating medium inlet; the right end of the first heating medium inlet is provided with a discharge outlet; the right side of the rack is provided with a heating medium pipe; the upper end of the heating medium pipe is provided with a second heating medium outlet; the lower end of the heating medium pipe is provided with a second heating medium inlet; the upper end, the lower end and the right side of the rack are provided with heating medium channels, so that the filtering chamber can constantly keep the constant temperature so as to guarantee that a polyester melt can flow in the filter; moreover, the melt outlet and the melt inlet are respectively provided with the filtered melt sampling valve and the unfiltered melt sampling valve which can be used for sampling the melt for observation, and once the polyester melt has a problem, measures can be taken immediately, and thus the scrapping of a great quantity of polyester melts can be prevented.
Description
Technical field
The utility model relates to a kind of polyester fondant filter, belongs to production of polyester technical field.
Background technology
In polyester production process, can filter melt, be used for removing aggregated particle and other impurity in melt.This filter is operated in (approximately 280 ℃ of temperature under high-temperature high-pressure state, pressure 100～200bar), and the ratio of viscosities of polyester fondant is higher, the mobile performance of melt is poor, once local temperature or pressure are inadequate, can cause local melt to remain static in filter, because long high temperature causes the polyester fondant even carbonization of degrading, when appearring in melt pipeline upward pressure, fluctuation has Partial digestion thing along with flowing of normal melt taken out of, thereby form " sandwich " particle, the purity of polyester fondant is affected.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of being heated evenly, and good filtration effect samples polyester fondant filter easily.
For achieving the above object, the technical solution of the utility model is: a kind of polyester fondant filter, comprise frame and be fixed on two filter chambers in frame, in filter chamber, be provided with filter core, the upper end of described filter chamber communicates with melt outlet, the lower end of filter chamber communicates with melt inlet, described melt outlet is provided with the rear melt sample valve of filter, melt inlet is provided with the front melt sample valve of filter, the upper end of described frame is laterally provided with the first heating agent outlet, the right-hand member of the first heating agent outlet is provided with exhaust outlet, the lower end of described frame is laterally provided with the first heating agent entrance, the right-hand member of the first heating agent entrance is provided with floss hole.
Further setting as such scheme: described frame right side is provided with heat medium pipe, the upper end of heat medium pipe is the second heating agent outlet, the lower end of heat medium pipe is the second heating agent entrance.
The beneficial effects of the utility model are: on upper end, lower end and the right side of frame, be provided with heat medium passage simultaneously, make the filter chamber in the middle of frame can keep stationary temperature always, guarantee that polyester fondant flows in filter, and the right-hand member at the first heating agent outlet and the first heating agent entrance is respectively equipped with exhaust outlet and floss hole, makes heating agent can keep unimpeded always and flow; And melt sample valve be provided with filter in melt outlet after, melt inlet is provided with the front melt sample valve of filter, can sample observation to filtering forward and backward melt, once find that polyester fondant goes wrong in sampling, can take immediate steps, avoid scrapping of a large amount of polyester fondants.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is top view of the present utility model.
Wherein: frame 1, filter chamber 2, cross melt sample valve 7a before melt sample valve 6a after filter core 2a, heat medium pipe 3, the second heating agent outlet 3a, the second heating agent entrance 3b, floss hole 4, exhaust outlet 5, melt outlet 6, filter, melt inlet 7, filter, the first heating agent entrance 8, the first heating agent outlet 9.
The specific embodiment
Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of polyester fondant filter of the utility model, comprise frame 1 and be fixed on two filter chambers 2 in frame 1, in filter chamber 2, be provided with filter core 2a, the upper end of described filter chamber 2 communicates with melt outlet 6, the lower end of filter chamber 2 communicates with melt inlet 7, described melt outlet 6 is provided with the rear melt sample valve 6a of filter, melt inlet 7 is provided with the front melt sample valve 7a of filter, the upper end of described frame 1 is laterally provided with the first heating agent outlet 9, the right-hand member of the first heating agent outlet 9 is provided with exhaust outlet 5, the lower end of described frame 1 is laterally provided with the first heating agent entrance 8, the right-hand member of the first heating agent entrance 8 is provided with floss hole 4.Described frame 1 right side is provided with heat medium pipe 3, and the upper end of heat medium pipe 3 is the second heating agent outlet 3a, and the lower end of heat medium pipe 3 is the second heating agent entrance 3b.
On upper end, lower end and the right side of frame 1, be provided with heat medium passage simultaneously, make the filter chamber 2 in the middle of frame 1 can keep stationary temperature always, guarantee that polyester fondant flows in filter 2, and the right-hand member at first heating agent outlet the 9 and first heating agent entrance 8 is respectively equipped with exhaust outlet 5 and floss hole 4, makes heating agent can keep unimpeded always and flow; And melt sample valve 6a be provided with filter in melt outlet 6 after, melt inlet 7 is provided with the front melt sample valve 7a of filter, can sample observation to filtering forward and backward melt, once find that polyester fondant goes wrong in sampling, can take immediate steps, avoid scrapping of a large amount of polyester fondants.
Polyester fondant enters filter chamber 2 from melt inlet 7, polyester fondant under the effect of the 2 inner filtration core 2a of filter chamber by its contaminant filter, polyester fondant after filtration enters next equipment from melt outlet 6, in filter process, can to melt, sample observation by melt filtration valve 7a after melt filtration valve 6a before filtering and filter.
