General wet spinning primarily of solidifying, spray washing, cold and hot baking, rolling, to oil/starching and a few procedure composition of heat treatment.
Prior heat treatment device divides two kinds: intermittent vacuum heat treatment and the heat treatment of single drying tunnel continous mode.Intermittent vacuum heat treatment is that the silk cylinder of spinning process rolling is put into multistation heat treatment still, and under vacuum condition, heat up, nitrogen is filled in cooling, drives still and obtains finished silk cylinder.The method has the large advantage for the treatment of capacity, but does not stretch to fiber due to during this device heat treatment, and molecularly oriented declines, and product mechanical performance reduces.The heat treatment of single drying tunnel continous mode is at some tension, in nitrogen protection, tow passes through heater continuously at a certain temperature, the method is suitable for the lower tenacity fibers of heat setting temperature below 300 DEG C, and aramid IIII fiber belongs to high-module high-strength special fibre, setting temperature is at 450 DEG C, therefore before and after sizing, the temperature difference is larger, " core " when the quick dehydration of fiber causes height-oriented, " table " layer produces hole, fibre machinery performance is not ideal, fibre strength is 4.5GPa, in addition, single drying tunnel continous mode heat treatment process amount is little, be difficult to meet large-scale industrial production.
Summary of the invention
The utility model is just for above technical problem, a kind of point of warm area multichannel burning optimization on line device is provided, adopting this device can overcome material makes fiber dry out fast in drawing-off weightlessness because being subject to excessive alternating hot and cold, " core ", " table " layer when causing height-oriented produces hole, the problem that fibre machinery performance is undesirable, can also overcome the shortcoming that single drying tunnel continous mode heat treatment process amount is little.
Concrete technical scheme of the present utility model is as follows:
Divide warm area multichannel burning optimization on line device, this device comprises thread supplying machine group, the first directive wheel, straining pulley, multichannel drying tunnel heater, the second directive wheel, the 3rd directive wheel and receipts silk unit, described thread supplying machine group is connected with multichannel drying tunnel heater with straining pulley by the first directive wheel successively, arrange warm area at multichannel drying tunnel heater, the rear end of multichannel drying tunnel heater is connected with receipts silk unit with the 3rd directive wheel by the second directive wheel successively.
Described warm area arranges 9, and the temperature of these 9 warm areas is respectively 250 DEG C-300 DEG C-350 DEG C-400 DEG C-450 DEG C-400 DEG C-350 DEG C-300 DEG C-250 DEG C.
A kind of point warm area multichannel burning optimization on line device that adopts carries out a point warm area multichannel burning optimization on line method, and the method comprises the following steps:
S1, heats up multichannel drying tunnel heater and reaches technological temperature;
S2, is filled with nitrogen in multichannel drying tunnel heater;
S3, puts web-like raw tow into thread supplying machine group;
S4, raw tow is released from thread supplying machine group, successively by the first directive wheel, straining pulley, multichannel drying tunnel heater, the second directive wheel, the 3rd directive wheel and receipts silk unit;
S5, receives silk unit by finished product tow last volume.
The temperature of described multichannel drying tunnel heater is multistage warm area graded, is divided into 9 warm areas according to heating-up temperature, successively by 250 DEG C-300 DEG C-350 DEG C-400 DEG C-450 DEG C-400 DEG C-350 DEG C-300 DEG C-250 DEG C during heat treatment of fiber.
24 parallel equally distributed passages are set in described multichannel drying tunnel heater and run through whole heater.
Owing to have employed this devices and methods therefor, make raw tow in heat treatment process, straining pulley is by tow tension signal feedback to spin bank, and spin bank controls spinning motor spinning speed, thus reaches heat treatment of fiber process identical tension raising molecularly oriented.Raw tow in the heater successively by each warm area, gradual intensification and cooling in each warm area.Being filled with nitrogen in warm area, protecting tow when being heated, not oxidation by air.
Good effect of the present utility model is embodied in:
(1), by adopting the method for multistage warm area graded in multichannel drying tunnel heater, fiber " core ", " table " layer porosity are reduced;
(2), adopt multichannel drying tunnel to process multi beam tow simultaneously, increase heat treatment process amount.
(3), can process multiple fibre, efficiency is higher simultaneously, can obtain steady quality, the fiber that intensity, elastic modelling quantity are higher.
