The utility model content
The purpose of this utility model be for overcome above-mentioned deficiency provide a kind of by the cleaning high-temperature gas make thermal source, add the new-type thermal source heater of plastic extruder of thermalization barrel, threeway, die head respectively by cartridge heater, flute profile heater.
The purpose of this utility model is achieved in that
The new-type thermal source heater of a kind of plastic extruder, comprising barrel, heater, threeway, die head, the outside of changing barrel, threeway and die head is provided with heater, the air inlet of heater is communicated with through the thermal source of pipe with the centralizedly supply hot-air, the outer wall of changing barrel, threeway and die head is provided with thermocouple, is equipped with the magnetic valve of control hot-air switching on the gas outlet of each heater.
Described thermal source is made up of shell, framework and pipe, pipe is loaded on the framework, thermal source is made up of the multilayer pipe, its neighbouring two-layer pipe is respectively vertical, transversely arranged, be provided with the passage that hot cigarette, flame pass through between the adjacent pipe of each layer, the diagonal angle of framework is fixed on the shell, establishes air inlet, inlet chamber and gas outlet and hot-air chamber on the shell, and air enters the hot-air chamber after pipe is heated.
Described magnetic valve is made up of valve body, valve plate, steel wire rope, pulley and electromagnet mechanism; Valve plate is positioned at the below of valve body baffle plate, and baffle plate is provided with the reference column of valve plate, and valve opening, the pulley of steel wire rope on baffle plate that is contained on the valve plate is connected with electromagnet mechanism.
The new-type thermal source heater of plastic extruder uses air heat, central heating, hot-air heats through cartridge heater handleization barrel, around being trapped among of the cartridge heater barrel, homogeneous heating, rapid, the gas outlet of cartridge heater is provided with magnetic valve, and this magnetic valve measures temperature by the thermocouple on the being located at barrel and design temperature is handled magnetic valve action, automation mechanized operation by electric part more again, guarantees temperature stabilization.Owing to use hot air, and do not compare not pollution with coal, liquefied gas heating, improved staff's environmental protection condition.Threeway and die head part because each one of complete machine all adopts hot air, are convenient to management also with hot air, have also saved electric energy.The outlet of the hot-air of cartridge heater and flute profile heater is connected on the pipe and discharges in addition, utilizes waste heat that water is heated.For having a bath or heat use.
