Boundling point being shaped by quenching from spinnerets to melt thread, in the distance more than this meter, has formed a variations in temperature field that has huge gradient, and this district is one of the most unsettled region, is also the region that industrial circle field management is focused on the most.In order to realize the object of stable state spinning, in this region, produce to be born and many monotechnics, as: the laminar flow implement device of the slow cooling technology having their own characteristics each, various net, pipe, nonwoven fabric, ring blowing technology, flat mouth oil etc., the application of these monotechnicss, promote product stable, affected the lifting of melt spinning industry quality of China and the tremendous development of scale.
The spray silk outlet position of spin mouthful-general reference filament spinning component, melt thus key position becomes thread, by cooling, solidify, stretch, become spun filament.If the temperature of spinning mouthful place sharply changes than temperature in spinning manifold, can make a big impact to the product quality of melt spinning.Therefore, be necessary to carry out structural optimization improvement to spinning the heater of mouthful position, to guarantee that it can guarantee to spin the stable of mouthful place's temperature, improves the end product quality of melt spinning.
Utility model content
Technical problem to be solved in the utility model is to provide mouthful heater that spins using in a kind of spinning production process, and it can effectively guarantee to spin the stable of mouthful place's temperature, thereby eliminates the defect in above-mentioned background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is:
That in a kind of spinning production process, uses spins a mouthful heater, be installed on spinnerets under, comprise base, sensor wire and magnetic conductor, described base is circular, and cross section is U-shaped, offers the import and export of described sensor wire on the sidewall of described base, the cross section of described sensor wire is oval, by described import and export, penetrate described base inner, and at the inner disk of described base around forming radio-frequency induction coil, and between adjacent windings, there is gap; The inner clamps of described base is equipped with described magnetic conductor, and described magnetic conductor is shaped as U-shaped, and is uniformly distributed in the inside of described base, and the radio-frequency induction coil that described sensor wire is formed is fixed; Described base inside is also filled with refractory seals packing layer, and described radio-frequency induction coil and the sealing of described magnetic conductor is fixing; On the outer wall of described base, be provided with fixture.Fixture is to be used for fixing base, base is fixed to the below of spinnerets.
As a kind of improvement, described base is 6061 aluminium alloy annulus.
As a kind of improvement, the internal diameter of described base is than the large 2mm of spinneret face diameter, and external diameter is than the large 40mm of internal diameter, and the height of described base is 35mm.
In the utility model, described refractory seals packing layer is the mixture of ceramic clay raw material and high temperature resistant binder, is solidified into one, and can not chaps through high-temperature process.
In the utility model, described magnetic conductor can be assembled magnetic flux, thereby improves the efficiency of heating surface, can also regulate the matching properties with high frequency induction power supply simultaneously.
As a kind of improvement, described sensor wire is the copper conductor of the coated temperature-resistant insulation layer of outer wall, and the specification of described copper conductor is 2 squares or 2.5 squares, and the number of turns of radio-frequency induction coil is determined according to heating power.
Spin mouthful heating as a crucial technology controlling and process point, significant.First, spin a mouthful heating and make spinnerets initiatively produce uniform heat energy, and realize essence control, on original environmental basis, reach the consistent continuously of plate surface temperature, the melt thread that guarantees each hole ejection is heated evenly, and guarantees that stable state continuous between monofilament is consistent from source.Secondly, do not changing under the condition of original related process, to spin mouthful Temperature Setting for the temperature same with spinning manifold, can reduce freezing point 3-10cm, the elongation of coiling fiber increases obviously, jet stretch ratio in technological design can increase, and after adjusting process, will improve at least production capacity of 2-3%.Again, spin mouthful temperature and can reach the temperature higher compared with spinning manifold, realize " melt relative low temperature in pipeline is carried, the high temperature spinning of moment " design of new processes.There is this three effect greatly, can derive the design direction of the aspects such as many related products performances, product variety, product category.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
This uses novel high-frequency induction to spin a mouthful heater, be arranged on filament spinning component under, temperature can be controlled between room temperature-350 ℃.This device can directly heat spinnerets by high frequency induction power supply, electric energy conversion is heat energy the various piece that is passed to rapidly spinnerets, on the basis of spinnerets original temperature, improve 5-15 ℃, thereby make the melt temperature flowing out from spinnerets than the high 5-10 ℃ of melt true temperature, reach the moment that melt flows out spinnerets spinneret orifice, tens, hundreds of so several thousand thread thermal histories consistent.Further can reduce screw rod transmission temperature and manifold equitemperature, reduce Energy Intensity Reduction cost, increase economic efficiency.
It is the extra cell equipment that is independent of spinning equipment that this high-frequency induction spins mouthful heater, heating system and tele-control system two parts, consists of, and can be applied to neatly all kinds of apparatus for melt spinning, and does not change structure and the flow process of original equipment.
In sum, the utility model can guarantee to spin the stable of mouthful place's temperature, improves the end product quality of melt spinning.
