Abstract
The invention discloses a novel extruder which comprises an extrusion barrel body, wherein a heating structure is arranged on the periphery of the extrusion barrel body; an insulation structure is arranged on the periphery of the heating structure; and the insulation structure comprises an insulation material layer and a vacuum insulation layer arranged in sequence from inside to outside. According to the novel extruder, a vacuum layer is arranged on the basis of the conventional insulation layer, so that the heat transfer quantity can be effectively reduced, the power energy can be saved and the production efficiency can be improved.
Description
Technical field
The present invention relates to the device of plastic processing technical field, be specifically related to a kind of novel extruder for extrusion plastic.
Background technology
At present, in the production process of plastics, need extruder, extruder is with the plastics heating and melting in the cylindrical shell and extrudes, the resistance wire heating is generally adopted in the heating of extruder at present, the temperature of extruder is very high, therefore need be at extruder barrel outer wrap heat-insulation and heat-preservation material, and the effect of heat-insulation and heat-preservation material is to prevent that the extruder heating heat scatters and disappears outsidely, improves the efficiency of heating surface of extruder; The 2nd, can be with high temperature and the external isolation of extruder, avoid the extruder environment temperature too high, also can avoid the generation of security incidents such as scalding, be 201020698988.0 as the patent No., and name is called: the extruder utility model patent of electromagnetism heating and heat-insulating device.This utility model discloses a kind of extruder electromagnetism heating and heat-insulating device, comprises that described insulation halfbody fits in tubular at least two insulation halfbodies that coat the extruder barrel external body.This electromagnetism heating and heat-insulating device is easy for installation, and thickness is even, makes the frequency stabilization of electromagnetic heater output, has also just prolonged the service life of electromagnetic heater, is convenient to the maintenance of extruder, has reduced installation and maintenance cost.
Yet just be entwined with the heat-preservation cotton scene in the cylindrical shell outside of extruder at present, but, inhomogeneous and the volume heaviness of heat-preservation cotton, make easily with the machine barrel heating heat and dissipate, because the extruder heater is consumable accessory, need periodic replacement, inconvenience is installed causes a lot of unnecessary troubles to production.
Summary of the invention
The present invention is intended to address the above problem to a certain extent.
Goal of the invention of the present invention is to overcome the defective of prior art, and a kind of high insulating effect is provided, the novel extruder of long service life.
For achieving the above object, the present invention adopts following technical scheme, a kind of novel extruder, comprise and extrude cylindrical shell, the described periphery of extruding cylindrical shell is provided with heating arrangement, affiliated heating arrangement periphery is provided with insulation construction, and described insulation construction comprises adiabator layer and the vacuum heat-insulating layer that sets gradually from inside to outside.
Under the normal pressure, the mutual bump between the thermo-molecular has caused heat to be propagated, and spread scope enlarging gradually, if when adopting vacuum layer, because the molecule in the vacuum layer is less, the number of times of the more few bump of molecule is also more little, and the spread speed of heat also descends thereupon.The present invention can effectively reduce the heat transmission by setting up one deck vacuum layer on the basis of existing heat-insulation layer, saves electric power energy, enhances productivity.
The present invention further improves and is that described heating arrangement is resistance wire, and the resistance wire heating is effective, and cost is cheap.
The present invention further improves and is, described adiabator layer is one or more composite in mineral wool goods layer, foam glass layer, expansion pearlite thermal insulation product layer, the cotton layer of mineral spraying.
The present invention further improves and is that the thickness of described vacuum heat-insulating layer is 10-15mm.
The invention has the beneficial effects as follows that the present invention can effectively reduce the heat transmission by setting up one deck vacuum layer on the basis of existing heat-insulation layer, save electric power energy, enhance productivity.
Description of drawings
Fig. 1 is the schematic diagram of invention structure.
Accompanying drawing only is used for exemplary illustration, can not be interpreted as limitation of the present invention; For better explanation embodiment, some parts of accompanying drawing have omission, amplify or dwindle, and do not represent the size of actual product; To those skilled in the art, in the accompanying drawing some known features and explanation thereof may to omit be understandable.
The specific embodiment
Describe structure of the present invention and operation principle in detail below in conjunction with accompanying drawing.
With reference to shown in Figure 1, novel extruder of the present invention comprises extrudes cylindrical shell 3, extrude on the periphery of cylindrical shell 3 electrical heating resistance wire 1 is housed, the periphery of resistance wire 1 is provided with one deck adiabator layer 2, and the periphery at adiabator layer 2 covers one deck vacuum heat-insulating layer 4 again, by vacuumizing, make vacuum shape grade attitude in the vacuum heat-insulating layer 4 inner appearance, vacuum refers in designated space, is lower than an atmospheric gaseous state.Vacuum is divided into different vacuum level according to different pressures, has respectively: low vacuum, middle vacuum, high vacuum, ultrahigh vacuum, XHV etc.The employed vacuum level of vacuum heat-insulating layer is middle vacuum pressure, and this is maximum vacuum field of using in most of vacuum techniques.Carry out heat insulationly at usual natural environment, middle vacuum level just can demonstrate enough heat-proof qualities.Under the normal pressure, the mutual bump between the thermo-molecular has caused heat to be propagated, and spread scope enlarging gradually, if when adopting vacuum layer, because the molecule in the vacuum layer is less, the number of times of the more few bump of the molecule also spread speed of more little heat also descends thereupon.The speed of calorie spread has descended, and the heat that distributes of machine barrel has also reduced so, thereby plays the effect of barrel zone temperature insulation.Save electric power energy, enhance productivity.
Describe the position relation in the accompanying drawing and only be used for exemplary illustration, can not be interpreted as the restriction to this patent.
Obviously, the above embodiment of the present invention only is for example of the present invention clearly is described, and is not to be restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.All any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the protection domain of claim of the present invention.
