Step 1：Flight is manufactured, the width of the flight is less than the internal diameter of the heat exchanger；
Step 2：One groove is respectively set on the flight two sides, and the groove extends along side；
Step 3：Using the central point of two neighboring flight two end faces adjacent to each other as tie point, multiple flights are connected,
Form a flight group；
Step 4：Solder is placed in the groove；
Step 5：The flight is assembled into the heat exchanger using tooling, the multiple flight is kept to be changed described
In hot device ontology, radially, there are a gaps with the heat exchanger inner wall；
Step 6：The solder is melted in heating, so that the flight group is fixedly connected with the heat exchanger, the flight group exists
It is all welded with the heat exchanger inner wall contact surface on entire hand of helix.
The present invention also provides a kind of heat exchangers of built-in flight, including flight group and heat exchanger body, the spiral shell
Rotation group is at least formed by connecting by two flights；Two neighboring flight is connection with the central point of two end faces adjacent to each other
Point connection；The flight group is axially distributed in the heat exchanger body；The flight two sides are respectively provided with recessed together
Slot, the groove extend along the flight side；The flight group on entire hand of helix in the heat exchanger
Wall contact surface is all welded.
Preferably, the flight group has a gap with the heat exchanger body inner wall.
Preferably, the two adjacent flights is of same size.
Compared with prior art, the technical advantages of the present invention are that：Due to having enough between flight and heat exchanger
Weld strength can effectively avoid flight occurs being extruded the accidents such as fall off, operation in highly viscous medium devolatilization processes
Securely and reliably.

Specific implementation mode
The present invention is further explained with reference to embodiment and attached drawing.Following embodiments do not limit this in any form
Invention.All technical solutions obtained by the way of equivalent substitution or equivalent transformation, be in protection scope of the present invention it
In.
Fig. 1 is the fluting dimensional drawing of flight 1；Fig. 2 is the schematic diagram for individually setting reeded flight 1.Such as Fig. 1 and figure
Shown in 2, the upper and lower end face of flight is of same size, and the flight is torsion point with the symmetrical centre of its own, with its own
It is rotary shaft in the symmetry axis of length direction, reverses 180 °.The centre of 1 side of flight be equipped with a road width b, the groove of deep a,
Middle a>B, the groove extend along the side of flight 1.
Fig. 3 is flight 1 and 2 welded section schematic diagram of heat exchanger body.Since flight 1 needs to be enclosed in after processing is completed
It is welded again in heat exchanger body 2, for the ease of flight 1 to be packed into heat exchanger body 2, flight 1 need to be kept and changed
Suitable fit-up gap c there are one being deposited between hot device ontology 2.In addition, in order to ensure between flight 1 and heat exchanger body 2
With enough weld strengths, the present invention uses Full connected face welding method, make flight 1 on entire hand of helix with change
Hot 2 contact surface of device ontology is all welded.The specific method is as follows,
Step 1：Flight 1 is manufactured, the upper and lower end face for controlling flight 1 is of same size, and width is less than heat exchanger body 2
Internal diameter.Flight 1 with the symmetrical centre of its own be torsion point, using its own length direction symmetry axis as rotary shaft, turn round
Turn 180 °.
Step 2：A groove is outputed centered on 1 two sides of flight by the symmetry axis of its length direction respectively, the groove
Wide b, deep a, and extend along 1 two sides of flight.
Step 3：Using the central point of two end faces adjacent to each other of two neighboring flight 1 as tie point, it is welded to connect multiple spiral shells
Blade 1 forms the flight group of a continuously coupled multiple flights 1.
Step 4：Solder 3 is fitted into the groove of 1 both sides of flight, solder is made to be full of entire groove.
Step 5：It recycles tooling that the flight of multiple flights 1 is assembled into heat exchanger body 2, keeps multiple flights 1
Flight group in axial direction placed in heat exchanger body 2, and there are a gap c with the inside of heat exchanger body 1.
Step 6：Heating fusing solder 3, solder 3 are flowed out from groove, are filled up between 2 inner wall of flight 1 and heat exchanger body
Gap makes the flight 1 be fixedly connected with heat exchanger body 2, it is ensured that flight 1 on entire hand of helix with heat exchanger sheet
2 inner wall contact surface of body is all welded.
Thus between the flight 1 and heat exchanger body 2 that are welded have enough weld strengths, heat and mass,
Liquid consolidates mixed process, especially in highly viscous media applications, avoids occurring flight and is extruded the accidents such as fall off, operation peace
It is complete reliable, improve working efficiency.
Fig. 4 is a kind of schematic diagram of the heat exchanger for the built-in flight for meeting the embodiment of the present invention.The heat exchanger includes changing
The flight group of hot device ontology 2 and continuously coupled multiple flights 1, flight group are in multiple in an axial direction in heat exchanger body 2
It is continuously distributed；Two neighboring flight 1 is connected by tie point of the central point of two end faces adjacent to each other；Flight 1 is whole
It is all welded with 2 inner wall contact surface of heat exchanger body on a hand of helix, the flight 1 being thus welded and heat exchanger sheet
There is enough weld strengths between body 2, in highly viscous medium devolatilization processes, generation flight can effectively be avoided to be squeezed
It has the accidents such as fall off, it is safe and reliable to operation.
It should be noted that the embodiment of the present invention has preferable implementation, and not the present invention is made any type of
Limitation, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above equivalent effective
