Description

Plastics, rubber installation electromagnetical heater
Technical field
The utility model relates to a kind of electromagnetic heater, specifically relates to a kind of plastics, rubber installation electromagnetical heater.
Background technology
Plastics, rubber processing industry are an industry of very popularizing, and especially plastic processing industry along with being extensive use of of plastic products, has become a kind of processing industry that must the old man can not leave.Need heat in plastics, rubber processing, existing mode of heating generally has two kinds:
First kind of scheme, it mainly comprises hopper, feed pipe, feeding spiro rod and resistance heater etc.Operation principle is: in the process, raw material is added by hopper, and under the promotion of screw rod, raw material progressively travels forward, because there is resistive heater heats the feed pipe outside, so plastic powders progressively liquefies, to satisfy the requirement of plastic processing.
Second kind of scheme, it mainly comprises hopper, feed pipe, feeding spiro rod and high frequency heating coil etc.Hopper, feed pipe, feeding spiro rod are identical with first kind, mode of heating difference only, and the former is the resistance heated mode, the latter is the electromagnetism mode of heating.
These two kinds of mode of heatings respectively have advantage, but also deficiency are arranged respectively.The former has satisfied technological requirement preferably, but power consumption is too big, and makes the environment temperature of working space be subjected to bigger influence.The latter has overcome the deficiency of the big and thermal pollution environment of the former energy consumption, but has also produced some problems.Mainly contain: 1. since coil on feed pipe, the axis of coil and the axis of plastic tube coincide.The magnetic line of force that coil produced has not only cut feed pipe, has also cut feeding spiro rod simultaneously.So in the heating feed pipe, also heat feeding spiro rod.Because the gap of feed pipe and feeding spiro rod very little (about general 0.14mm) is so it is stuck that the screw rod overheating deforming just might make it, and causes equipment breakdown.2. require the temperature of feed pipe different parts can be controlled on the technology, thus the segmentation heating required, and this mode of heating is because coil is an integral body, so, implement comparatively difficulty.3. this whole processing mode that twines is not suitable for producing in enormous quantities.4. install, keep in repair all very inconveniently, and, cause bigger loss in case damage is scrapped with regard to integral body.
Summary of the invention
The purpose of this utility model just is to provide a kind of deficiency that overcomes above-mentioned two schemes.The advantage and the high frequency electric source electromagnetism heating and energy saving and the advantage of improving environment that also have the easy segmentation heating of resistance heated simultaneously.
The purpose of this utility model can realize by following measure:
The utility model comprises hopper, hopper is provided with feed pipe, the center of feed pipe is a screw rod, end at feed pipe is provided with die head, be provided with semicircle asbestos housing in the feed pipe external symmetry, be wound with magnetizing coil in the asbestos housing, the axis of magnetizing coil and the axis of feed pipe are perpendicular; Die head is provided with the asbestos housing, and the asbestos housing is provided with magnetizing coil, and the axis normal of described magnetizing coil is in the die head plane.
Outside described feed pipe, be symmetrically arranged with a plurality of semicircle asbestos housings in the utility model vertically.It is a side of die head or the both sides that lay respectively at the die head plane that asbestos housing that is provided with on the described die head and magnetizing coil are distributed in.
The utlity model has following advantage, 1. owing to having adopted the electromagnetism heating, so still kept energy-saving advantages.2. because the flow direction of magnetic flux is perpendicular to the axis of feed pipe, under the shielding of feed pipe, there are not a large amount of magnetic lines of force directly to cut feeding spiro rod, so, have only the feed pipe heating, feeding spiro rod then can not generate heat in a large number, and this has also just prevented because the undue caused stuck phenomenon of thermal deformation.3. owing to segmentation (be divided into four sections among the figure, will be determined on a case-by-case basis in the actual the use) mode of heating that has adopted as resistance heated, so can satisfy the requirement of segmentation control temperature on the technology.4. simultaneously, because the effect that prevents thermal radiation has objectively been played in the existence of asbestos housing, thereby, saved energy, improved workman's working environment.5. owing to be designed to the part of semicircle one by one, be suitable for mass production.Easy for installation, easy to maintenance.Even if damage, also can not just all scrap quickly, therefore, saved maintenance cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of feed pipe, screw rod and asbestos housing in the utility model;
Fig. 3, Fig. 4 all are principle schematic of magnetizing coil and binding post in the asbestos housing in the utility model.
Fig. 5 be in the utility model die head and on the asbestos housing and the structural representation of magnetizing coil.
The specific embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises hopper 1, hopper 1 is provided with feed pipe 2, the center of feed pipe 2 is screw rods 3, end at feed pipe 2 is provided with die head 7, be provided with semicircle asbestos housing 5 in feed pipe 2 external symmetrys, be wound with magnetizing coil 4 in asbestos housing 5, the axis of the axis of magnetizing coil 4 and feed pipe 2 is perpendicular; Die head is provided with the asbestos housing, and asbestos housing 5 is provided with magnetizing coil, and the axis normal of described magnetizing coil is in the die head plane.The utility model is symmetrically arranged with a plurality of semicircle asbestos housings 5 vertically outside described feed pipe 2.It is a side of die head or the both sides that lay respectively at the die head plane that asbestos housing that is provided with on the described die head and magnetizing coil are distributed in.Label 6 is the binding post on the magnetizing coil 4.
Operation principle of the present utility model is as follows: the utility model adopts 20-40KHz high frequency electric source electromagnetism mode of heating.Specific practice is seen Fig. 1, Fig. 2, Fig. 3, Fig. 4.The basic principle of Fig. 3, Fig. 4 is identical, and just difference slightly on magnetic circuit is indicated in the branch Fabric situation map of the magnetic line of force, can use in different occasions.Fig. 4 uses when for example can heat in the plane.
The utility model is owing to having adopted the electromagnetism heating, so still kept energy-saving advantages; Because the flow direction of magnetic flux is perpendicular to the axis of feed pipe, under the shielding of feed pipe, does not have a large amount of magnetic lines of force directly to cut feeding spiro rod, so, have only the feed pipe heating, feeding spiro rod then can not generate heat in a large number, and this has also just prevented because the undue caused stuck phenomenon of thermal deformation; Owing to adopted segmentation (be divided into four sections among the figure, will be determined on a case-by-case basis in actual the use) mode of heating, so can satisfy the requirement of segmentation control temperature on the technology as resistance heated; Simultaneously, because the effect that prevents thermal radiation has objectively been played in the existence of asbestos housing, thereby, saved energy, improved workman's working environment; Owing to be designed to the part of semicircle one by one, be suitable for mass production.Easy for installation, easy to maintenance.Even if damage, also can not just all scrap quickly, therefore, saved maintenance cost.The utility model not only can be used for plastics, rubber equipment, and the electromagnetism that also can be used for other fields such as metallurgy, mould adds to be pined for.
