The utility model is simple in structure and convenient to use, effectively reduces the radiation injury on the human body, solves the problem of damage due to interference in the frequency converter and microcomputer, saves the electric power by 30-60%, and thus, is safe, energy-saving and environment-friendly.
Description
(1) technical field
The utility model belongs to technical field of heating, particularly a kind of electromagnetic induction heating injection-moulding device electricity-saving appliance.
(2) background technology
At present; various plastics machineries such as the employed injection machine of people, comminutor, blow moulding machine are famous electricity-eating tigers; wherein all be to adopt heating wire, electrothermal tube heating; utilization rate is extremely low, can reach about 60%, has 40 ~ 50% heat energy to run off in air; can not take full advantage of; not only increase cost to manufacturing industry, polluted environment, also be easy to generate unsafe factors such as electric leakage.
Along with science and technology development, new technology continues to bring out, and has occurred a collection of technological innovation personnel in recent years and has already made various reducing energy consumption schemes for injection moulding, but still it is not thoroughly perfect, for example, aspect temperature control, exchange too frequent starting of contact aspect, reduced the service life of A.C. contactor; For another example, very big injury and damage that high frequency radiation interference aspect does not have solution that human body and frequency converter, micro computer are caused produce the secondary pollution problem to electrical network especially and do not solve.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of electromagnetic induction heating injection-moulding device electricity-saving appliance of simple in structure, environmental protection and energy saving is provided.
The utility model is achieved by the following technical solution:
A kind of electromagnetic induction heating injection-moulding device electricity-saving appliance, comprise the power-supply filter that is communicated with alternating current circuit, it is characterized in that: described power-supply filter is connected with the full bridge PWM current rectifying and wave filtering circuit, the full bridge PWM current rectifying and wave filtering circuit connects the button solenoid by the control drive circuit, the water-cooled constant temperature system that connection arranged side by side is installed on the control drive circuit be connected switching system.
The utility model connects the full bridge PWM current rectifying and wave filtering circuit at power-supply filter, prevents that clutter from injecting electrical network, and the water-cooled constant temperature system has guaranteed the accuracy of temperature control, effectively realizes the integrated of button solenoid and temperature control system.
More excellent scheme of the present utility model is:
Described button solenoid is for adding the device of pyroceram fibre open type fastener type insulating tube in metal cylinder, eliminate and wrap after the heat-preservation cotton mounting means of winding again on the virgin metal tube, and repair and replacement are convenient, and temperature control is accurate simultaneously.
Be coated with high frequency radiation protection bisque on the insulating tube of described button solenoid, effectively solve the radiation injury to human body.
The utility model is simple in structure, and is easy to use, effectively reduced the injury to human body radiation, solved the infringement that frequency converter, micro computer are disturbed, and power saving rate can reach 30 ~ 60%, energy-saving safe and environmental protection.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 power-supply filter, 2 full bridge PWM current rectifying and wave filtering circuits, 3 control drive circuits, 4 button solenoids, 5 water-cooled constant temperature systems, 6 connect switching system, 7 insulating tubes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the power-supply filter 1 that is communicated with alternating current circuit, described power-supply filter 1 is connected with full bridge PWM current rectifying and wave filtering circuit 2, full bridge PWM current rectifying and wave filtering circuit 2 connects button solenoids 4 by control drive circuit 3, the water-cooled constant temperature system 5 that connection arranged side by side is installed on the control drive circuit 3 be connected switching system 6; Described button solenoid 4 is for adding the device of pyroceram fibre open type fastener type insulating tube 7 in metal cylinder; Be coated with high frequency radiation protection bisque on the insulating tube 7 of described button solenoid 4.
The utility model adopts the high-frequency induction heating principle to convert electric energy to heat energy, at first by power-supply filter 1 alternating current of 50Hz is become direct current, converting direct current to high frequency voltage that frequency is 16 ~ 28KHz through the full bridge PWM current rectifying and wave filtering circuit, the electric current that changes can produce the magnetic field that changes at a high speed by button solenoid 4 and metal under the effect of control drive circuit 3 at a high speed, when the magnetic line of force in the magnetic field passes through by metal object, can in being heated metal object, produce countless little eddy current, be heated metal object heating at a high speed itself thereby make; Reach by the water-cooled constant temperature system 5 on the temperature control control system circuit and to be heated the required temperature of equipment barrel and to implement, simultaneously by connecting the switching on and shutting down frequency that switching system 6 has reduced the temperature control A.C. contactor of this equipment, prolonged the service life of this equipment, eliminate radiation, reach the personal safety purpose, its system thermal efficiency easy for installation has obtained energy-saving and environmental protection that whole utilization reaches, purpose of safety.
