Description
Technical field
The present invention relates to a kind of energy saver, especially a kind ofly can solve the device that there is the waste of energy problem in using in plastic machine, be applicable to the energy-saving device of plastic machine of injection machine, comminutor, extruder, wire drawing machine barrel.
Background technology
At present, the energy-conservation existing a variety of modes of plastic machine barrel are like simple barrel stay-warm case; Electromagnetism mode of heating etc.
Study, test discovery for a long period of time through me: because of the barrel heating-up temperature generally all between 180 ℃-500 ℃ and environment temperature have the very big temperature difference, the big more thermal loss of the temperature difference is many more.So simple stay-warm case mode power savings is not obvious, generally about 10%.Because meeting is because of the friction self-heating in the plastic material process, causing unnecessary heat to distribute and not going out influences product quality simultaneously.Another kind of power-economizing method is the electromagnetism mode of heating, and its principle is that the power frequency supply with 50Hz is reverse into high frequency electric source about 20000Hz and acts on and produce eddy current on the barrel and make the barrel self-heating.The method heats to compare with the conventional, electric-resistance formula can economize on electricity about 30%-70%, and energy-saving effect is preferably arranged.
Also there is following weak point in but above-mentioned battery saving mode:
1), the work of great-power electromagnetic heating controller the time can produce a large amount of harmonic waves, pollute electrical network and cause the improper use of other electrical equipment (like the plastic machine electric motor frequency converter) sometimes.
2), a plurality of electromagnetic heater can produce mutual interference effect when heating a barrel simultaneously, can cause the controller life-span short, fault rate is high.
Above reason makes above-mentioned two kinds of power-economizing methods just local on probation in practice for many years, is not extensively promoted.Based on the weak point of above-mentioned two kinds of battery saving modes, the inventor has designed the present invention's " a kind of energy-saving device of plastic machine ".
Summary of the invention
The technical problem not enough to be solved that the present invention is directed to above-mentioned prior art is: provide a kind of and can solve the device that has the waste of energy problem in the plastic machine use, be applicable to the energy-saving device of plastic machine of injection machine, comminutor, extruder, wire drawing machine barrel.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of energy-saving device of plastic machine comprises barrel, is provided with the resistance heated circle in the barrel periphery; The resistance heated circle outside is coated with outer guard shield, and the resistance heated circle below of barrel downside is glued with an electromagnetism and adds hot iron plate, and this electromagnetism adds the hot iron plate below and is provided with the arc solenoid; The arc solenoid is connected with electromagnetic controller through lead; Electromagnetic controller is connected with power supply, the outer guard shield inboard insulation reservoir that has been sticked, and insulation reservoir inboard is a thermal reflective material layer.The present invention adopts original resistance heated circle of plastic machine and the coefficient mode of electromagnetism afterburner to heat.The solenoid of barrel bottom began to produce high frequency magnetic field when the original resistance heated circle of barrel passed to barrel along circumference with heat during work under the effect of electromagnetic controller; High frequency magnetic field acts on the iron plate of barrel bottom; Make the rapid heating up of iron plate; From the lower heating barrel, make the heating power of barrel bottom obviously greater than the heating power at side direction and top, utilize heat energy to greatest extent according to the principle of heat rising.Be dispersed into barrel heat on every side and returned heating cylinder by the heat-reflecting material coating, insulation reservoir and outer guard shield acting in conjunction prevent heat-energy losses.When the indivedual warm areas of barrel occurring and exert an influence the unnecessary heat of product quality because of the plastic material frictional heat; Can open the top heat dissipating housing discharges unnecessary heat; When the no unnecessary frictional heat that influences product quality, cover heat dissipating housing and reach the fully efficient of heat energy and utilize.
Described outer guard shield is provided with and is used for heat dissipating housing that unnecessary heat is discharged, and the quantity of heat dissipating housing is one or more.
The bottom of described each heat dissipating housing heat preserving and insulating material layer that has been sticked.
Described outer guard shield is processed by metal or nonmetallic materials.
The beneficial effect of a kind of novel electromagnetic induction heating collar of the present invention is:
Through this power save mode, improved heat utilization efficiency, thereby improved power saving rate; Solved owing to distribute the problem of product quality that influences of not going out because of the unnecessary heat of friction self-heating in the plastic material process; Utilize the fast advantage of electromagnetism firing rate, the shortcoming that adopt the mode of the quick concurrent heating of unit small-power promptly to avoid the great-power electromagnetic heater to use to pollute electrical network to avoid again working simultaneously to influence each other, fault rate is high because of a plurality of electromagnetic heaters.
