Abstract
The utility model relates to a non-woven fabrics device, in particular an electromagnetic heating device comprising a material canister, a screw arranged inside the material canister, and an insulation cloth, a heat-insulation layer A, copper wire, and a heat-insulation B which are wound outside around the material canister from interior to exterior. The output frequency of the copper wire is controlled by a host similar to a frequency modulator, thereby realizing high frequency heating, with the control temperature being measured by a temperature control meter and being substantially automatic control. After being electrified, the copper generates high frequency waves, thus to heat the screw. As an integral heating manner is adopted, the electromagnetic heating device features uniform and rapid heating and requires relatively low power. The most critical point lies in that the heat preservation is directly wrapped to the screw, preventing heat loss in principle, thereby achieving the effect of environmental protection and energy saving. The insulation cloth and the heat-insulation layer wound around the screw prevent heat loss.
Description
Technical field
The utility model relates to a kind of non-woven fabrics apparatus, relates in particular to a kind of electromagnetic heating apparatus.
Background technology
Nonwoven fabrics claims adhesive-bonded fabric again, be to constitute by fiber orientation or at random, be environment-friendly materials of new generation, have protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, cheap, capable of circulation characteristics such as use again.Many employing polypropylene (pp material) pellets are raw material, batch continuous one-step and produce through high-temperature fusion, spray silk, shop guiding principle, hot pressing.Because of outward appearance and some performance with cloth are called cloth.Because it is a kind of fabric that does not need to spin cotton and weave cloth and form, just textile staple or long filament are carried out orientation or support row at random, form fibre net structure, adopt methods such as mechanical, hot sticky or chemistry to reinforce then and form.It is not by one one yarns interwoven, woollen yarn knitting together, but with fiber directly method by physics be bonded together, will find so take nonwoven fabrics, be can not take out one by one the end of a thread.Non-weaving cloth has been broken through traditional weaving principle, and has that technological process is short, speed of production is fast, output height, characteristics such as cost is low, purposes is wide, raw material sources are many.But in the existing equipment of producing nonwoven fabrics, the place of screw rod heating all is to adopt the electric heating piece, but the electric heating piece, and power consumption is big, heats inhomogeneously, has reduced product quality.
Summary of the invention
The utility model is big at power consumption in the prior art, heats inhomogeneously, has reduced the deficiency of product quality, and a kind of electromagnetic heating apparatus is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Electromagnetic heating apparatus comprises barrel, and barrel inside is provided with screw rod, and the barrel outside is wound with empire cloth, heat-insulation layer A, copper cash and heat-insulation layer B from the inside to the outside.Copper cash is by the host computer control output frequency that is similar to frequency modulator, thereby reaches high-frequency heated, measures the control temperature by temp controlled meter, all is automation control basically.Copper cash energising back produces high frequency waves, thus heating spiral rod.Because be whole heating, so homogeneous heating, speed is fast, and required power is little, most critical is to be incubated directly to be wrapped in screw rod, has stopped the heat loss in principle, thereby has reached environmental protection, energy-conservation effect.Empire cloth that twines on the screw rod and heat-insulation layer have all prevented scattering and disappearing of heat.
As preferably, heat-insulation layer A is the asbestos tegillum, and described heat-insulation layer B is the heat-preservation cotton layer.
As preferably, barrel is provided with temperature-sensing probe.Obtain temperature signal by temperature-sensing probe and compare output switching signal control frequency modulator to the induction coil power output, produce high frequency waves through temp controlled meter, thus heating spiral rod.
According to the technical solution of the utility model, electromagnetic induction efficient is than higher, and heating is fast rapidly, current wave is little, and particularly after the insulation, heat does not run off basically, and energy-conservation and the working environment of workers are had very big improvement.Initial estimate is energy-conservation about 40%, and ambient temperature can descend 20 ℃.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The 1-barrel, 2-screw rod, 3-empire cloth, 4-heat-insulation layer A, 5-copper cash, 6-heat-insulation layer B, 7-temperature-sensing probe.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Embodiment
With reference to the accompanying drawings 1, electromagnetic heating apparatus comprises barrel 1, and barrel 1 inside is provided with screw rod 2, and barrel 1 outside is wound with empire cloth 3, heat-insulation layer A4, copper cash 5 and heat-insulation layer B6 from the inside to the outside.Heat-insulation layer A4 is the asbestos tegillum, and heat-insulation layer B6 is the heat-preservation cotton layer.Also be provided with temperature-sensing probe 7 on the barrel 1.Obtain temperature signal by temperature-sensing probe 7 and compare output switching signal control frequency modulator to the induction coil power output, produce high frequency waves through temp controlled meter, thus heating spiral rod 2.Copper cash 5 is by the host computer control output frequency that is similar to frequency modulator, thereby reaches high-frequency heated, measures the control temperature by temp controlled meter, all is automation control basically.Copper cash 5 energising backs produce high frequency waves, thus heating spiral rod 2.Because be whole heating, so homogeneous heating, speed is fast, and required power is little, most critical is to be incubated directly to be wrapped in screw rod 2, has stopped the heat loss in principle, thereby has reached environmental protection, energy-conservation effect.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
