The inductance coil displacement-type is regulated the automatic temperature control system of materail tube heating
Technical field
The utility model belongs to the adjustment control technology field to materail tube, particularly includes the materail tube that material flows in pipe, the materail tube thermoregulating system that carries out temperature adjustment with inductance coil displacements mode.
Background technology
Thereby now with heating materail tube, be, give materail tube with the heat conduction of resistance-type heating piece, and materail tube is heated at a plurality of resistance-types heating of the outer bread of materail tube piece to the materail tube that the flowable materials in the materail tube heats.It is with air blast resistance-type heating piece to be dried that adjusting promptly reduces the materail tube temperature, reduces the temperature of resistance-type heating piece, reduces the materail tube temperature indirectly.Its weak point is: the heat major part of resistance-type heating piece rejects heat in the ambient air, wasted heat, waste electric energy, but also to producing thermal pollution around the resistance-type heating piece.If the temperature of resistance-type heating piece will be raised to more than 70 ℃, then resistance-type heating piece is dangerous to the people on every side.So the technology to the materail tube heating is that power consumption, cost are high, the adventurous technology of possibility now.
The utility model content
The purpose of the utility model provides materail tube external inductance coil position is moved the automatic temperature control system of regulating the materail tube temperature.
The syndeton of the utility model is:
The inductance coil displacement-type is regulated the automatic temperature control system of materail tube heating; Comprise metal tube 1, master controller 11, electric conduction quantity controller 13 and motor 16; It is characterized in that: the outer surface of metal tube 1 is with a plurality of movably nonmetallic rings 14, is wound with inductance coil 3 on the nonmetallic ring 14; Nonmetallic ring 14 or inductance coil 3 are connected with movable mechanism 15, and movable mechanism 15 is connected with motor 16, are connected with displacement controller 17 between motor 16 and the master controller 11;
Be provided with temperature sensor 10 in the metal tube 1, temperature sensor 10 is connected with master controller 11, and master controller 11 is connected with electric conduction quantity controller 13, and electric conduction quantity controller 13 is connected with inductance coil 3.
For inductance coil 3 can outside metal tube 1, be slided, so be wrapped in inductance coil 3 slidably on the nonmetallic ring 14.Movable mechanism 15 can drive nonmetallic ring 14 or inductance coil 3 can slide inductance coil 3 at metal tube 1 outer surface; Regulate the position of adjacent two inductance coils 3; Under the constant situation of the electric conduction quantity that faces two inductance coils 3; Distance between these two inductance coils 3 is near more, and metal tube 1 temperature between these two inductance coils 3 is high more; Distance between these two inductance coils 3 is far away more, and metal tube 1 temperature between these two inductance coils 3 is low more.
A kind of concrete metal tube 1 and inductance coil 3: the interior diameter of metal tube 1 is 10--20 centimetre, and inductance coil 3 is when 210-400 volt power supply, and the inductance of inductance coil 3 is the 50-500 microhenry.This is a kind of inductance type heating materail tube that is fit to do the plastic rubber shaping machine, and the plastic material in the metal tube 1 can be heated to 400 ℃.
The advantage of the utility model: regulate the metal tube temperature and can use and regulate between adjacent two inductance coils distance and regulate recently, can reduce the cold wind that reduces temperature and take away heat, reduce thermal loss, save approximately.
