This exhaust gas entered in preheating outer tube 25 is finally drawn delivery pipe 19 from tail gas and is discharged, and since exhaust gas itself is with very high
Temperature, thus into feeding pipe 13 and preheating outer tube 25 between cavity after, may be implemented to expects pipe 13 very using high-temp waste gas
Good preheating and heat preservation, at this time the material in expects pipe 13 can not only be preheated, but also can be with insulation, for cold zone
For avoid using additional heat-preserving equipment in, whole equipment, reduce energy consumption, while also avoiding material and the feelings freezed occur
Condition, integral extrusion process are more smooth.
The expects pipe 13 is made of channel steel material, whole to have preferable heat conductivility, and the outside of pre- hot blast pipe 16
It is cased with collet, can prevent pre- hot blast pipe 16 from excessive outside heat dissipation occur in this way.
The stirring tank body 1 is fixedly mounted on using screw on tank body supporting rack 10.
Sample tap is offered on the outer wall of the stirring tank body 1, and the sample tap goes out to be connected with probe tube 15.
It is also cased with collet on the outer wall of the preheating outer tube 25.
The present invention operation principle be：Into the exhaust gas in preheating outer tube 25 finally 19 row of delivery pipe is drawn from tail gas
Go out, and since exhaust gas itself has very high temperature, into after the cavity between feeding pipe 13 and preheating outer tube 25, utilize
High-temp waste gas may be implemented to preheating and the heat preservation well of expects pipe 13, and the material in expects pipe 13 can be both preheated at this time, together
When can avoid again in, whole equipment using additional heat-preserving equipment for cold zone, reduce energy consumption with insulation,
The case where material freezes is also avoided simultaneously, integral extrusion process is more smooth.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
