Description
Technical field
The present invention relates to industry light industry textile industry equipment and technical field, especially a kind of CATION POY spinning manifold on-line cleaning device and cleaning method.
Background technology
Present domestic chemical fiber factory POY fused mass directly spinning mainly has greatly light to produce, half delustring conventional variety is as main, plant area of Hang Seng of Tongkun Group Zhejiang Prov Hengsheng Chemical Fiber Co., Ltd be domestic unique one produce differential CATION POY directly spin enterprise.Compare with conventional variety, added the 3rd monomer in the CATION production process, cohesion, gel-like impurity is more, and the fondant filter cycle (filtering accuracy 25U), generally about 8 days, conventional variety was about 3 months.The filament spinning component cycle also obviously shortens, 300D/96F be the example CATION cycle about 10 days, conventional variety is about 75 days.To compare the CATION fluidity of molten poor with conventional variety, and fusing point is low, easily degraded, and the melt pipeline accompanies hot temperature low, the easy ramming material of tube wall, melt impurity is many simultaneously, and filter, assembly cycle are short, because the coking degree is different, cause the weight silk more etc.
Comprehensive above-mentioned reason, the melt pipeline is peeled off in the CATION spinning manifold material and impurity are higher because of Hang Seng's long filament 8 line output, increase therefore relatively flow into 8 line impurity, cause in the spinning pump, impurity coking situation is comparatively serious in the casing melt pipeline.8 line 13# bit tests are observed, spun 300D/96F, the lower assembly of dismounting is opened measuring pump, and pressure is 14Mpa behind the pump, and upper assembly is opened measuring pump, and pressure is 21Mpa behind the pump.Upper machine pressure illustrates that considerably beyond normal range (NR) the tube wall coking and blocking is serious.With steel wire rope casing melt pipeline is imported and exported and to be cleared up, black coking solids is more, and the coking of measuring pump outlet tube wall is also very serious, and caliber coking diminishes closely 60%, has had influence on melt flow.8 line 1# bit tests observation there is kindred circumstances.
Summary of the invention
But the objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind of CATION POY spinning manifold on-line cleaning device and cleaning method of on-line cleaning spinning manifold.
In order to achieve the above object, the CATION POY spinning manifold on-line cleaning device that the present invention is designed, it mainly comprises casing, be provided with the melt pipeline in the casing, measuring pump on the casing is removed, and install measuring pump base blind plate, outlet at bottom half is connected to purge tank by connector, and purge tank passes through thermometer, Pressure gauge successively, safety valve, delivery pump, safety valve is connected with return tank, and return tank is connected with filter, filter is connected with casing by measuring pump bottom blind plate, is communicated with outdoor by safety valve on the return tank simultaneously.
As optimization, described blind plate is connected the device of high-temperature fusant outlet for blocking the high-temperature fusant import.
All devices all adopt the stainless steel 304 material.
Above-mentioned connector adopts flange to connect, and uses gasket seal, and gasket seal is stainless steel tetrafluoro spirotallic gasket.
Purge tank is provided with cooling water coil simultaneously.
The method of CATION POY spinning manifold on-line cleaning is at first removed measuring pump, installs the measuring pump blind plate, and with pressure-air the melt pipeline is purged; Secondly, install such as claim 1 to device claimed in claim 5; The 3rd step added salpeter solution in purge tank, and open delivery pump salpeter solution is circulated, and record delivery pump outlet initial pressure; In the 4th step, when the salpeter solution temperature rises to 50 ℃, by cooling water coil nitric acid is cooled off, make salpeter solution remain on 75-85 ℃, after 72 hours, stop circulation until the salpeter solution circulation, cleaning is finished, and discharges after simultaneously the air in the return tank being filtered by clear water.
In the cleaning process, running parameter is set as follows
1, salpeter solution delivery temperature: 80 ℃
2, spin manifold temperature: 280 ℃
3, pump flow: 3m
2/ hour
4, delivery pump outlet pressure 260KPa
5, casing inlet pressure 200KPa.
6, cooling box volume 100L.
7, return tank body bulk 80L.
8, cooling water flow: 3m
2/ h.
The resulting CATION POY spinning manifold of the present invention on-line cleaning device and cleaning method, the coking that it can effectively be known in the casing can make spinning manifold run well, and reduces spinning broken end phenomenon, improves equipment operating efficiency.In addition, use this Apparatus and method for to clean, need not to stop, but on-line cleaning does not affect the production of another spinning station of same casing, enhances productivity, and reduces production costs, and increases economic efficiency.
