Description
Technical field:
The utility model relates to the electromagnetic heating technique field, more specifically to a kind of electromagnetic heater of Controllable Temperature.
Background technology:
Existing plastics machinery adopts the resistance-type heating mostly; Mode through the contact conduction is transmitted to heat on the barrel; Its weak point is: only be absorbed near the inboard heat of barrel; And run off near the heat in the barrel outside is most of, to also have a shortcoming be exactly that power density is low in the resistance wire heating in addition, has some to need the higher occasion of temperature just can't adapt to.
Electromagnetic heating technique is to make metal barrel self-heating, and as the case may be at the certain heat-insulation and heat-preservation material of barrel outer wrap, so just significantly reduces the loss of heat; Improved the thermal efficiency; Can reach more than 96%, so power savings very significantly can reach more than 30%; And firing rate raising 60%, saved preheating time greatly.Its weak point is: because the outer wall of barrel is processed by insulation material; So its heat radiation is slow, heat radiation needs long time, has influenced operating efficiency; The temperature of barrel can't accurately be controlled simultaneously, the needs that in the time of can't satisfying some plastic processings temperature accurately required.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art, and a kind of electromagnetic heater of Controllable Temperature is provided, and its rapid heat dissipation can accurately be controlled the temperature in the barrel in the process.
The technological solution of the utility model is following:
A kind of electromagnetic heater of Controllable Temperature; Comprise barrel, insulation layer, solenoid support, solenoid and support; The external packets of barrel is covered with the insulation layer, and the external stability of insulation layer has the solenoid support, and solenoid is wound on the solenoid support that insulating materials manufactures; The solenoid support is fixed on the support; Clamping has the high molecular nanometer alloy material to manufacture the wind guide tank that forms between barrel and the insulation layer, forms several apertures on the wind guide tank, and the wind of air blast is to wind guide tank.
Said wind guide tank is weldingly fixed on the barrel.
Said wind guide tank is shaped as frame.
The beneficial effect of the utility model is:
1,, can reduce the temperature of barrel fast through air blast in wind guide tank, so its rapid heat dissipation owing on the barrel outer wall, be furnished with wind guide tank.
2, it adopts nano-high molecule alloy Heat Conduction Material to manufacture wind guide tank; Form cooling control tunnel; And on nano-high molecule alloy Heat Conduction Material, carry out the aperture design; When the wind of air blast is blown over, can accurately control the temperature in the barrel, to satisfy temperature controlled requirement in the process from wind guide tank.

Among the figure: 1, barrel; 2, wind guide tank; 21, aperture; 3, insulation layer; 4, solenoid; 5, support; 6, solenoid support; 7, air blast.
The specific embodiment:
Embodiment: see shown in Fig. 1 to 4; A kind of electromagnetic heater of Controllable Temperature comprises barrel 1, insulation layer 3, solenoid support 6, solenoid 4 and support 5, and the external packets of barrel 1 is covered with insulation layer 3; 3 external stability of insulation layer have solenoid support 6; Solenoid 4 is wound on the solenoid support 6 that insulating materials manufactures, and solenoid support 6 is fixed on the support 5, the wind guide tank 2 that clamping has the high molecular nanometer alloy material to manufacture to form between barrel 1 and the insulation layer 3; Form several apertures 21 on the wind guide tank 2, the wind of air blast 7 is to wind guide tank 2.
Said wind guide tank 2 is weldingly fixed on the barrel 1.
Said wind guide tank 2 is shaped as frame.
Operation principle: owing on barrel 1 outer wall, be furnished with wind guide tank 2, can reduce the temperature of barrel 1 fast through air blast in wind guide tank 2, so its rapid heat dissipation.
It adopts nano-high molecule alloy Heat Conduction Material to manufacture wind guide tank 2; Form cooling control tunnel, and on the wind guide tank 2 that nano-high molecule alloy Heat Conduction Material is manufactured, carry out aperture 21 designs, when the wind of air blast 7 is blown over from wind guide tank 2; The insulation layer 3 that utilizes aperture 21 to manufacture to the ventilative material of asbestos is ventilative; And directly dry to barrel 1 through wind guide tank 2, can accurately control the temperature in the barrel 1, to satisfy temperature controlled requirement in the process.
Temperature control in the barrel 1; Can in barrel 1, temperature probe be set; The temperature signal of temperature probe flows to plastics machinery switch board main frame, sends the size of command signal control air blast 7 air quantity by plastics machinery switch board main frame, thereby realizes accurately controlling the temperature in the barrel 1.
