The utility model content
Purpose of design: for avoiding the deficiency in the background technology, design a kind of ECDP spinning drying system of effective reduction spinning chips moisture.
Design: for realizing above-mentioned purpose of design.1, crystallizing bed inside is provided with the zone one that top communicates successively, zone two and zone three, one bottom, zone is provided with air inlet one, this air inlet one is connected with heater one by pipeline, two bottoms, zone are provided with air inlet two, this air inlet two-way piping is connected with heater two, heater one is connected with air blast by pipeline respectively with heater two, three bottoms, zone are provided with discharging opening, this discharging opening links to each other with drying tower by pipeline, heater threeway piping one end links to each other with drying tower, the other end links to each other with dehumidifying machine, the outlet that a crystallizing bed side is equipped with pan feeding three-way pipe and pan feeding three-way pipe is positioned at zone one, crystallizing bed top is provided with the gas outlet, this gas outlet links to each other with the garbage collection storehouse by pipeline, the material mouth that blows of suction blower fan is connected by pipeline with the import of pan feeding three-way pipe, the top ports in the material sucking port of suction blower fan and garbage collection storehouse is one of technical characterictic of the present utility model by the design that pipeline is connected.The purpose of design is like this: in the one-tenth product process of terylene, the height that the section moisture content is done in spinning will directly affect the state of spinning and the quality of product quality.The wet section of spinning is after passing through the pan feeding three-way pipe, successively through the crystallizing bed zone of setting up separately, zone two and zone three, in experience zone one by heater one and air blast combination from bottom providing warm air and zone two by heater two and the air blast combination drying from the bottom providing warm air, spinning chips will form crystallizations regional three, after the spinning chips crystallization, to enter the drying tower drying, dry warm braw is anhydrated gas by dehumidifying machine and forms by heater three behind the gas in the drying tower, guaranteed that crystallization can be by the steam secondary pollution, dry crystallization needs through sampling after the assay was approved again, just can carry out discharging production, spinning chips is when crystallizing bed middle drying crystalline, there are sub-fraction spinning chips and dust to enter the garbage collection storehouse by crystallizing bed gas outlet, this spinning chips will carry out recycle by the suction blower fan through after filtering.This system is low and stable at chip drying process Air dew point, and the section moisture content generally is lower than 50ppm after dry, and intrinsic viscosity falls also less than 0.02dl/g, and the spinning quality of production is better.2, the design of filter is installed in the pipeline between suction blower fan and garbage collection storehouse, is two of technical characterictic of the present utility model.The purpose of design is like this: in dry run, sub-fraction spinning chips and dust enter the garbage collection storehouse by crystallizing bed gas outlet, spinning chips utilizes again by the suction blower fan, in the pipeline between suction blower fan and garbage collection storehouse filter is installed, can Chalk-dust filtering, improve the degree of purity of the spinning chips of recycling.3, lower end, garbage collection storehouse is connected to the design of dust bucket, is three of technical characterictic of the present utility model.The purpose of design is like this: after the whole system running, will assemble a large amount of dust things in the garbage collection storehouse, termination dust bucket can in time be processed the dust accumulation thing under the garbage collection storehouse, and whole system is normally moved.4, the bottom of drying tower is equipped with discharge nozzle, and this discharge nozzle is two to be in charge of and two to be in charge of the middle design that discharge valve and Sampler valves are installed respectively, is four of technical characterictic of the present utility model.The purpose of design is like this: it is an important physical index that the section moisture content is done in spinning, its height will directly affect the state of spinning and the quality of product quality, bottom at drying tower is equipped with discharge nozzle, this discharge nozzle is two to be in charge of and two to be in charge of middle discharge valve and the Sampler valves installed respectively, can open at any time the Sampler valves sampling, judge whether section enhydrous amount is done in spinning up to standard, thereby determine whether to open the discharge valve blowing.5, heater one heating-up temperature is at 60 ℃-80 ℃, and heater two heating-up temperatures are five of technical characterictics of the present utility model 120 ℃-140 ℃ design.The purpose of design is like this: enter the wet section of regional a pair of spinning after the wind that air blast produces is heated to 60 ℃-80 ℃ by heater one and carry out preliminarily dried, and be blown into regional two, spinning chips is accepted the warm braw of heater two heating-up temperatures to 120 ℃-140 ℃ in zone two dry, and be blown into regional three, in the drying through zone one and zone two, spinning chips forms crystallization regional three.6, the lower port of pan feeding three-way pipe is equipped with the design of capping, is six of technical characterictic of the present utility model.The purpose of design is like this: because the wet section of spinning humidity is high, viscosity is strong, has after entering the pan feeding three-way pipe and long-pendingly cover even stops up three-way pipe, the lower port of pan feeding three-way pipe is equipped with capping, can remove when many amassing to cover like this, can dredge during obstruction.
