Technical Field

The utility model relates to an improvement invention of coarse filter, especially relate to an improvement invention of coarse filter based on cock switching.

Background

In the chemical fiber production process, the filter mainly plays a role in filtering impurities or gel particles which can influence the subsequent process in the melt to be clean so as to improve the purity of the melt. The traditional single-cylinder pipeline coarse filter needs frequent cleaning in the working process, and the production needs to be stopped during cleaning, so the production efficiency is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a coarse filter based on cock switches.

In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize: this kind of coarse filter based on cock switching, including filter body, last fuse-element import, fuse-element export and the drain of being equipped with of filter body, the drain has set blowoff valve, its characterized in that: still be equipped with on the filter body and control two filter chambers that distribute, be equipped with first coarse filtration core and the coarse filtration core of second in two filter chambers respectively, first coarse filtration core and the coarse filtration export intercommunication melt export and the drain of the coarse filtration core of second, the filtration import and the melt import of the coarse filtration core of first coarse filtration core, the coarse filtration core of second communicate a cylindricality chamber respectively, are equipped with the plug valve sealed firmly with it in the cylindricality chamber, and this plug valve can select to switch on filtration import and the melt import of first coarse filtration core or the filtration import and the melt import of the filter core of second.

The first coarse filter element and the second coarse filter element respectively comprise a coarse filtering porous pipe and a filter main body, and the upper end of the coarse filtering porous pipe is connected into the lower port of the filter main body by threads.

The valve cavity opening of the plug valve communicated with the melt inlet is larger than the melt inlet, and a flow guide column is arranged in the corresponding valve cavity.

The plug valve is provided with a rotary limiting structure.

The rotary limiting structure comprises a horizontal swing arm fixed at the upper end of the plug valve and two longitudinal limiting columns fixed at the upper end of the filter body, and the horizontal swing arm is limited in the two longitudinal limiting columns to rotate.

The utility model has the advantages that the improved coarse filter based on cock switching improves the defect that the traditional single cylinder pipeline coarse filter needs to be cleaned when frequently switched, adds a function of rotary switching, can switch coarse filtering on line, and greatly improves the production efficiency; the coarse filtering porous pipe is detachable from the filtering main body, so that residual materials in the coarse filtering porous pipe can be conveniently cleaned after switching; the flow dividing column is arranged in the plug valve, so that the problem of dead zones when the melt passes through the valve cavity is reduced.

Detailed Description

The drawings show the structure of the present invention, and the details thereof will be further described with reference to the drawings. In the embodiment, the coarse filter based on cock switching comprises a filter body 1, wherein a melt inlet 2, a melt outlet 3 and a sewage outlet 4 are arranged on the filter body 1, the sewage outlet 4 is provided with a sewage valve 5, the filter body 1 is also provided with two filter chambers 6 distributed left and right, a first coarse filter element 7 and a second coarse filter element 8 are respectively arranged in the two filter chambers 6, namely, two cylinder bodies are adopted and are respectively hard-sealed with the first coarse filter element 7 and the second coarse filter element 8, so that the disassembly and the installation of a sealing gasket are omitted; first coarse filtration core 7 and the filtration export intercommunication melt export and drain 4 of the coarse filtration core 8 of second, the filtration import of the first coarse filtration core 7, the filtration import and the fuse-element import 2 of the coarse filtration core 8 of second communicate a cylindricality chamber respectively, are equipped with the plug valve 9 of hard seal with it in the cylindricality chamber, and this plug valve 9 optional switches on the filtration import and the fuse-element import 2 of the first coarse filtration core 7 or the filtration import and the fuse-element import 2 of the second filtration core.

As a further improved embodiment, each of the first coarse filter element 7 and the second coarse filter element 8 comprises a coarse filter perforated pipe 10 and a filter main body 11, wherein the upper end of the coarse filter perforated pipe 10 is connected in the lower port of the filter main body 11 by screw threads, and the detachable arrangement is convenient for cleaning internal residues after switching.

As a further improved specific implementation mode, the valve cavity opening of the plug valve 9 communicated with the melt inlet 2 is larger than the melt inlet 2, namely the plug valve and the melt inlet 2 are communicated in the rotating process, the corresponding valve cavity is internally provided with a flow guide column 12, and the flow guide column 12 reduces the problem of dead zones existing when the melt passes through the valve cavity.
