Abstract
Provided is a reverse-flow melt filter. The problems that in an existing melt filter, the cost can be increased and the melt purity can be influenced under the conditions that an inlet is high and an outlet is low are solved. The reverse-flow melt filter comprises a heating box body and a filter chamber, a filter core is arranged in the filter chamber, the two ends of the filter chamber are connected with an inlet pipe and an outlet pipe respectively, the outlet pipe is placed at the upper end of the outlet pipe, switching valves are arranged both in the inlet pipe and the outlet pipe, a vent valve is arranged at the end, close to the inlet pipe, on the filter chamber, and a blow-down valve is further arranged on the outlet pipe. According to the reverse-flow melt filter, the production line that melt goes in from the upper position, goes out from the lower position, goes in from the outside and goes out from the inside, and exhausts gas and sewage is used in the reverse-flow melt filter which is mainly suitable for a polymer continuous spinning production line which requires a high inlet and a low outlet. The reverse-flow melt filter is compact and reasonable in structure, the empty volume inside the filter is the smallest, the standing time of the melt is the shortest, and the quality of products is guaranteed.
Description
Technical field
The utility model relates to the filter plant in a kind of chemical fibre production, is specifically related to a kind of reverse-flow fondant filter.
Background technology
In production of chemical fibres, the Main Function of filter is that impurity or the gel particles that can affect later process in melt are filtered totally, to improve the purity of melt.Conventional fondant filter be all use very low with import and on polymer continuous spinning production line that outlet is very high, even import is very high, in the lower situation of outlet, be also to adopt the pipeline connection of going for a stroll, can produce following consequence like this: 1, pipeline lengthens, increase the time of staying of material in filter, affected the quality of product; 2, the volume of filter strengthens, so the also corresponding increasing of the floor space at user scene, comprises all corresponding increases of energy consumption, has increased greatly the production cost of product.
Summary of the invention
Export a lot of costs of lower meeting increase for solving existing fondant filter in background technology in the situation that import is high, and affect the problem of melt purity, the utility model provides a kind of reverse-flow fondant filter.
The technical solution of the utility model is: a kind of reverse-flow fondant filter, comprise heating casing and filter chamber, be provided with filter core in described filter chamber, the two ends of described filter chamber join with inlet tube and outlet respectively, described inlet tube is positioned at the upper end of outlet, be equipped with transfer valve on described inlet tube and outlet, described filter chamber is provided with air bleeding valve at the end near inlet tube, also is provided with drain valve on described outlet.
As a kind of improvement of the present utility model, described filter chamber is by push rod vertical hanging and heating casing.
As further improvement of the utility model, the bottom of described filter chamber is arc surface, and described outlet inserts in filter chamber and be corresponding with its arc surface.
As further improvement of the utility model, described heating casing is provided with a plurality of heating agent interfaces.
As further improvement of the utility model, the transfer valve on described inlet tube and outlet is three-way switch valve.
The beneficial effects of the utility model are, polymer melt enters filter chamber by inlet pipeline, get rid of the air in filter chamber when switching, filter core was housed in filter chamber, melt passed through filter core under the effect of pressure, and impurity is stayed in filter chamber, and the material after filtration flows into down equipment one by outlet, the bottom of filter is provided with drain valve, after switching for the melt in emptying filter chamber.Filter of the present utility model adopts the melt upper entering and lower leaving, goes out in advancing outward, the production line of exhaust blowdown, mainly is applicable to require import very high and go out on lower polymer continuous spinning production line.The utility model compact conformation is reasonable, the empty volume minimum of filter interior, and the time of staying of melt is the shortest, has guaranteed the quality of product.
The accompanying drawing explanation
The structural representation that accompanying drawing 1 is the utility model embodiment.
In figure, 1, the heating casing; 2, filter chamber; 21, filter core; 22, arc surface; 3, inlet tube; 4, outlet; 5, transfer valve; 6, air bleeding valve; 7, drain valve; 8, push rod; 9, heating agent interface.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of reverse-flow fondant filter, comprise heating casing 1 and filter chamber 2, and specifically, described heating casing 1 is provided with a plurality of heating agent interfaces 9.Be provided with filter core 21 in described filter chamber 2, the two ends of described filter chamber 2 join with inlet tube 3 and outlet 4 respectively, described inlet tube 3 is positioned at the upper end of outlet 4, be equipped with transfer valve 5 on described inlet tube 3 and outlet 4, specifically, the transfer valve 5 on described inlet tube 3 and outlet 4 is three-way switch valve.Described filter chamber 2 is provided with air bleeding valve 6 at the end near inlet tube 3, on described outlet 4, also is provided with drain valve 7.The beneficial effects of the utility model are, polymer melt enters filter chamber by inlet pipeline, get rid of the air in filter chamber when switching, filter core was housed in filter chamber, melt passed through filter core under the effect of pressure, and impurity is stayed in filter chamber, and the material after filtration flows into down equipment one by outlet, the bottom of filter is provided with drain valve, after switching for the melt in emptying filter chamber.Filter of the present utility model adopts the melt upper entering and lower leaving, goes out in advancing outward, the production line of exhaust blowdown, mainly is applicable to require import very high and go out on lower polymer continuous spinning production line.The utility model compact conformation is reasonable, the empty volume minimum of filter interior, and the time of staying of melt is the shortest, has guaranteed the quality of product.
Described filter chamber 2 is by push rod 8 vertical hangings and heating casing 1.Such structure makes after transfer valve work, as long as first open drain valve, drains the melt in filter chamber, unclamps push rod and can hang out easily filter chamber and cleaned.
The bottom of described filter chamber 2 is arc surface 22, and it is interior and corresponding with its arc surface 2 that described outlet 4 inserts filter chamber 2.Such structure does not have dead angle while making melt discharge, and is convenient to lasting production and processing product.
Every technical staff's notice: although the utility model describes according to the above-mentioned specific embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
