Abstract
The utility model relates to an electric heating ring comprising a shell body, wherein heating tubes made of quartz tubes are uniformly distributed in the shell body, the outer face of the shell body is covered with a C-shaped thermal insulation layer, the two ends of the thermal insulation layer are provided with a connection mechanism, the shell body and the thermal insulation layer are made of stainless steel and therefore the shell body and the thermal insulation layer are improved in strength coefficient, a screw bolt runs through via holes and therefore the two ends of the thermal insulation layer are connected, the electric heating ring can be adjusted to an appropriate tightness degree according to actual demand, the electric heating ring cannot be broken due to excessive applied force in work processes, and therefore the service life can be greatly prolonged.
Description
Technical field
The utility model relates to a kind of electric heating coil of plastic extrusion facility.
Background technology
Electric heating coil is to be mainly applied in industrial production as heater element, for example, in the application of injection machine.At present in actual applications, because the pressure ratio to electric heating coil is larger, the ambient pressure maximum that especially electric heating coil junction is subject to, can make junction very easily rupture, and the life-span of electric heating coil is reduced greatly.
Utility model content
For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of electric heating coil that can greatly reduce electric heating coil junction generation fracture possibility.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of electric heating coil, comprise housing, and in housing, be uniformly distributed heating tube, described heating tube is quartz ampoule, this housing outside is coated with heat-insulation layer, and heat-insulation layer is " C " font, and these heat-insulation layer two ends are provided with bindiny mechanism.
Further, described bindiny mechanism comprises two hollow cylinders, and this hollow cylinder is welded in respectively heat-insulation layer two ends.
Further, in described hollow cylinder, be placed with joint pin, in the middle of joint pin, have through hole, pass through hole by bolt heat-insulation layer two ends are connected.
Further, described heat-insulation layer and surface of shell adopt stainless steel manufacture.
Compared with prior art, the utility model has the advantage of: first housing and heat-insulation layer all adopt stainless steel, increase its strength factor, secondly, pass through hole by bolt heat-insulation layer two ends are connected, can regulate according to actual needs, be adjusted to a suitable elasticity, electric heating coil is just can be not stressed not excessive and rupture at work, greatly improves the life-span.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing, embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of electric heating coil, comprise housing 1, in housing, 1 is uniformly distributed heating tube, described heating tube is quartz ampoule, this housing 1 outside is coated with heat-insulation layer 2, heat-insulation layer 2 is " C " font, these heat-insulation layer 2 two ends are provided with bindiny mechanism 4, described bindiny mechanism 4 comprises two hollow cylinders, this hollow cylinder is welded in respectively heat-insulation layer 2 two ends, in described hollow cylinder, be placed with joint pin 4, in the middle of joint pin 4, have through hole 5, through through hole 5, heat-insulation layer 2 two ends are connected by bolt 6, described heat-insulation layer 2 and housing 1 surface adopt stainless steel manufacture, housing and heat-insulation layer all adopt stainless steel, increase its strength factor, secondly, passing through hole by bolt connects heat-insulation layer two ends, can regulate according to actual needs, be adjusted to a suitable elasticity, electric heating coil is just can be not stressed not excessive and rupture at work, greatly improve the life-span.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, it will be understood by those of skill in the art that its technical scheme that still can record aforementioned each embodiment modifies, or part technical characterictic is wherein replaced on an equal basis; And these amendments or replacement do not make the essence of appropriate technical solution depart from spirit and the scope of the each embodiment technical scheme of the utility model.
