Abstract
The utility model discloses an efficient electric heating coil suitable for injection molding machines, plastic extruders, bottle blowing machines, mold blowing machines and a number of mechanical screw rod heating devices. The electric heating coil comprises an electric heating body, a fastening screw arranged on the electric heating body and a connection terminal, wherein an insulation cover is arranged on the electric heating cover. According to the efficient electric heating coil, the electric heating body and the insulation cover are perfectly combined, so that the electric heating body becomes a single-surface inward-heating structure from the primary two-surface radiation structure during the heating process, and has the effect that heat loss closes to zero and achieves the energy-saving purpose.
Description
Technical field
The utility model relates to a kind of electric heating coil, the heat efficient electric gas ket of plant equipment of particularly a kind of injection machine, plastic extruder, bottle blowing machine, blow molding machine of being applicable to, and some screw rods.
Background technology
Electric heating coil occurring on the market mainly is by electric heating element and holding screw, and binding post forms.Its middle connecting terminal is installed on the electric heating element, and is connected with the wire of drawing on the electric heating element.During use, suppose that electric heating coil is under the heated condition, its inside and outside meeting produces a large amount of heats.Because the lateral surface of electric heating coil and contact with air, the phenomenon of heat energy loss appears easily, cause the waste of large volume and electricity, so there is the poor problem of energy-saving effect in present electric heating coil.
The utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of efficient electric gas ket.
For achieving the above object, the utility model provides a kind of efficient electric gas ket, comprises electric heating element and the holding screw on electric heating element, and binding post.Wherein be provided with stay-warm case on the electric heating element.Thus; the electric heating element periphery is equipped with the heat insulation stay-warm case that prevents that heat runs off of tool; so that electric heating element becomes present single face to the structure of internal heat generation by original two sides heat radiation in heating process; the heat of protection electric heating element inwardly can outwards not dispel the heat all the time and hold; improved the efficient of electric heating coil periodic duty, the energy-conservation purpose of realization.
In some embodiments, stay-warm case comprises the shell that is connected with electric heating element and the insulation bag that is provided with between shell and electric heating element.Thus, so that stay-warm case is easier when assembling; Also be more convenient for being incubated the replacing of bag.
In some embodiments, shell is folding U-shaped shell, forms annular compartment between folding U-shaped shell and the electric heating element, and the insulation bag is arranged in the annular compartment.Thus, adopt folding U-shaped shell mechanism, guaranteed that the installation of insulation bag puts in place more.
In some embodiments, binding post is arranged on the folding U-shaped shell.Thus, main purpose is that convenient wire of drawing from electric heating element can be received on the binding post.
In some embodiments, insulation comprises the glass fabric of insulation material and parcel insulation material.Thus, the structure of parcel realizes heat insulation or prevents that heat runs off close to zero effect.
Description of drawings
Fig. 1 is the structural representation of the efficient electric gas ket of the utility model one embodiment;
Fig. 2 is after Fig. 1 launches, the structural representation of folding U-shaped shell and insulation bag decomposing state;
Fig. 3 is after Fig. 1 launches, and folding U-shaped shell and insulation package close the structural representation of state.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Show that such as Fig. 1 to 3 a kind of efficient electric gas ket comprises electric heating element 1 and the holding screw on electric heating element 17, and binding post 8.Electric heating element 1 mainly is the stainless steel electric heating coil, injection machine electric heating coil, mica stainless steel heating circle, the thermal-insulating type electric heating coil, braiding line-outgoing type electric heating coil, plasticity machines electric heating coil, lead-in wire nozzle type electric heating coil, porcelain joint formula electric heating coil, energy-saving electrical gas ket, mica electric heating coil, the plug-type electric heating coil, the extruder electric heating coil, energy-saving heating circle, mica ceramics electric heating coil, the empennage-type electric heating coil, ceramic electric heating ring, ceramic stainless steel heating circle, desk-top outlet electric heating coil, lead-in wire band cellular type electric heating coil, the thickening type electric heating coil, cast aluminium electric heating coil, cast copper heating circle etc.
Be provided with stay-warm case 2 on the lateral surface of electric heating element 1.Stay-warm case 2 comprises the shell that is connected with electric heating element 1 hinge 3 and the insulation bag 4 that is provided with between shell and electric heating element 1.
Shell is folding U-shaped shell 5, and this folding U-shaped shell 5 is connected by two semicircle U-shaped shell 6 hinges 3 and forms, and realizes folding function.After namely two semicircle U-shaped shells 6 are surrounded electric heating element 1, fix two semicircle U-shaped shells 6 with holding screw 7.Form annular compartment between folding U-shaped shell 5 and the electric heating element 1, insulation is wrapped 4 and is arranged in the annular compartment, and binding post 8 is arranged on the folding U-shaped shell 5 of wire 9 opposite positions of drawing from electric heating element 1.Insulation bag 4 comprises the glass fabric of insulation material and parcel insulation material, wherein insulation material such as asbestos and alumina silicate etc.
During use, first that the holding screw 7 on the electric heating element 1 is fixing tight; Afterwards insulation bag 4 is put into folding U-shaped shell 5 inside, the folding U-shaped shell 5 that closes, and fixing with holding screw 7; At last the wire 9 of drawing on the electric heating element 1 is linked on the binding post 8.
Above-described only is embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
