Description of drawings
Fig. 1 is the structural representation of the electro-heat equipment of the preferred drying machine of the utility model;
Fig. 2 is the schematic cross-section of the electro-heat equipment of the preferred drying machine of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of electro-heat equipment 100 of drying machine, and this electro-heat equipment 100 comprises heat generating core 10 and the outer tube 20 that is sheathed on heat generating core 10 outsides.The outer tube 20 preferred metal materials that adopt are processed, and the top of outer tube 20 connection air-supply arrangement 30, and said air-supply arrangement 30 is preferably fan or air blast etc.The bottom of outer tube 20 connects drying machine 200.Also be provided with an even numbers mutually nested interior pipe between electro-heat equipment 10 and the outer tube 20; Pipe in for example mutually nested two, pipe etc. in pipe or six in four; Form ventilating duct between the every adjacent body of outer tube 20 and interior pipe; After air-supply arrangement 30 forms wind, also finally directly send wind to drying machine 200 through said ventilating duct, to realize the function of drying material by the interior pipe of innermost layer.Why the utility model adopts the individual interior pipe of even numbers, is because an even numbers interior pipe can be realized the one-way transmission of wind, and promptly on wind direction, hot blast can finally directly be sent into drying machine 200 through innermost interior pipe; And if adopt pipe in the odd number, hot blast just can be sent to drying machine 200 after can innermost in, producing revolution in the pipe at last, during can generation hot blast adverse current to outer tube 20, cause thermal loss.
The even numbers of a utility model mutually nested interior pipe can be realized good thermal insulation protection between heat generating core 10 and outer tube 20, guarantee that heat can not run off through outer tube 20, makes that the programming rate of electro-heat equipment 30 is fast and more energy-conservation.Obviously the pipe number is many more in being provided with, and effect of heat insulation is good more, but cost also can improve relatively.
Preferably, heat generating core 10 can be heating sheet, heating wire, heat-generating pipe or thick film heating layer.And; The top of outer tube 20 connects air-supply arrangement 30 through first ring flange 21; The bottom of outer tube 20 is through the hopper 201 of second ring flange, 22 connection drying machines 200, and said drying machine 200 is preferably injection molding drier, can dry the plastic material in the hopper 201 like this.Said outer tube 20 is preferably cylindrical or square column type with interior pipe, can certainly be other arbitrary shapes.
In the utility model preferred embodiment; Be provided with two mutually nested interior pipes between electro-heat equipment 10 and the outer tube 20; As depicted in figs. 1 and 2, comprise in first and manage 50 in the pipe 40 and second that the width of outer tube 20 is greater than the width of the first interior pipe 40; Can form first ventilating duct 61 between the tube wall of pipe 40 in the outer tube 20 and first like this; The width of pipe 40 is greater than the width of pipe 50 in second in first, can form second ventilating duct 62 between the tube wall of pipe 50 in the pipe 40 and second in such first, and the width of pipe 50 is greater than the width of heat generating core 10 in obvious second.Managing 50 in first in the pipe 40 and second is preferably processed by metal material.Outer tube 20 comprises closed type top 21 and closed type bottom 22.Manage 40 in first and comprise closed type top 41 and open-type bottom 42, and the 42 closed type bottoms 22 than outer tube 20 exceed first length relatively bottom the open-type of the first interior pipe 40, can be communicated with first ventilating duct 61 and second ventilating duct 62 like this.Pipe 50 comprises open-type top 51 and open-type bottom 52 in second; The closed type top 41 of open-type top 51 to the first interior pipes 40 of pipe 50 hangs down second length relatively in second; The inside that so just can be communicated with pipe 50 in second ventilating duct 62 and second, and the open-type bottom 52 of pipe 50 extends into drying machine 200 in second.Be more preferably, the closed type top 41 of the first interior pipe 40 is back taper, more helps the circulation of hot blast.Certainly, pipe in four even the more even numbers can be set also, only need to guarantee hot blast through behind some ventilating ducts, the hopper of directly sending into drying machine 200 via pipe in innermost gets final product.
Like this; After heat generating core 10 heating; Air-supply arrangement 30 is sent wind to drying machine 200 through the open-type bottom 52 of pipe 50 in the open-type top 51 and second of pipe 50 in the open-type bottom of pipe in first ventilating duct 61, first 42, second ventilating duct 62, second, constitutes a unidirectional aeration structure on the whole, and it not only can send hot blast into drying machine 200; And can between heating core 10 and outer tube 20, carry out thermal insulation protection, pass through outside outer tube 20 losses extremely to avoid heat.
In sum; The utility model is through being provided with an even numbers mutually nested interior pipe between electro-heat equipment and outer tube; Form ventilating duct between the every adjacent body of said outer tube and interior pipe, air-supply arrangement is also finally sent wind to drying machine by the interior pipe of innermost layer through said ventilating duct.Because an even numbers mutually nested interior pipe not only can ventilate; And can the heat between heat generating core and the outer tube be carried out well heat insulation; Heat can not run off through outer tube again; Thereby can realize good thermal insulation protection, make that the programming rate of electro-heat equipment is fast and more energy-conservation, and keep good working environment.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
