Description
Technical field
The present invention relates to the processing and manufacturing technology of multiple spiral coil pipe, specifically a kind of few head spiral coil and its group
The method for dressing up large-scale multiple spiral coil pipe.
Background technology
Spiral coil is the conventional heat exchange element of boiler of organic heat carrier or heat exchanger, is using similar multiple-threaded shape
Many steel pipe disks are made the heat exchange element of cylindrical shape by formula（Referring to Fig. 1）.As the power of boiler and heat exchanger constantly increases,
Requirement to spiral coiler capacity of equipment is also accordingly improved constantly, and the demand of large-scale multiple spiral coil pipe also gradually increases,
But the ability of existing spiral coiler cannot gradually meet production requirement, become the bottle of high-capacity boiler and heat exchanger
Neck.And the relatively costly of large-scale coiler is purchased, enterprise's manufacturing cost is increased, and as high-capacity boiler and heat exchanger are produced
Amount is few, and large-scale coiler utilization rate of equipment and installations can be caused low.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of few head spiral coil and its assembling
Into the method for large-scale multiple spiral coil pipe, the technology can substantially reduce the requirement to spiral coiler capacity of equipment, not increase
In the case that oil (gas) filling device puts into, it becomes possible to produce large-scale multiple spiral coil pipe.
According to the technical scheme that the present invention is provided：Few head spiral coil, it is characterised in that：Few head spiral coil includes
At least one parallel helical tube body for being close to coil, leaves gap between the adjoining spiral coiling circle on few head spiral coil, should
Integral multiple of the width in gap for single spiral tube body caliber.
As a further improvement on the present invention, the helical tube body quantity in few head spiral coil is 1 ~ 4.
The method that few head spiral coil is assembled into large-scale multiple spiral coil pipe, it is characterised in that comprise the steps：
（1）, select multiple few spiral coils for matching, the lead of screw angles of described multiple few head spiral coils will
Unanimously, the gap between the adjoining spiral coiling circle on one of spiral coil will be with the coiled coil on remaining spiral coil
Circle width sum is adapted；
（2）, two of which few head spiral coil placed in the way of end vis-a-vis, axial line are coaxial, then make
They translate opposite close, the rotation in translation motion adjusts the relative position of the two so as in a few head spiral coil
Helical disk pitch of the laps termination alignment continues logical in the gap between the adjoining spiral coiling circle on another few head spiral coil
The two few head spiral coil nestings are combined into one by the mode for crossing rotation propulsion；If the few helical disk of more than three
Pipe is combined, and remaining few head spiral coil is combined also according to above-mentioned steps are nested；
（3）, few whole spiral coils carry out shaping after combining, make all of few head spiral coil keep flat
Together, that is, make large-scale multiple spiral coil pipe.
The present invention compared with prior art, with advantages below：The present invention rationally utilizes existing spiral coiler, not
In the case of increasing equipment investment, by the improvement of process meanses, large-scale multiple spiral coil pipe is succinctly effectively produced, reduced
Equipment investment cost and cycle, solve the bottleneck problem of high-capacity boiler and heat exchanger.

Specific embodiment
The embodiment combined in accompanying drawing is further described by the present invention below：
Embodiment 1
As shown in Fig. 2 embodiment 1 is a kind of two spiral coils, which is by two parallel 1 group of helical tube bodies for being close to coil
Into, gap 3 is left between the adjoining spiral coiling circle 2 on two spiral coils, the width d in the gap 3 is single spiral tube
2 times of 1 caliber r of body.
Embodiment 2
As shown in figure 3, embodiment 2 is a kind of three spiral coils, which is by three parallel 1 group of helical tube bodies for being close to coil
Into, gap 3 is left between the adjoining spiral coiling circle 2 on three spiral coils, the width d in the gap 3 is single spiral tube
3 times of 1 caliber r of body.
Embodiment 3
Embodiment 3 is that two spiral coils in Fig. 2 and three spiral coils in Fig. 3 are assembled into medium-and-large-sized five spiral shells of Fig. 1
The method of capstan pipe, which comprises the steps：
1st, using existing spiral coiler, by spiral coiler capacity of equipment scope, by controlling spiral coiler
Lead angle coils the adjoining spiral of few spiral coil and formed between circle 2 gap 3, bends out two spiral coils in Fig. 2
It is consistent with the lead of screw angle of three spiral coils in Fig. 3, two spiral coils and three spiral coils, two spirals
The 3 width d of gap between adjoining spiral coiling circle 2 on coil pipe is mutually fitted with 2 width D of helical disk pitch of the laps on three spiral coils
Match somebody with somebody；
2nd, two spiral coils and three spiral coils are placed in the way of end vis-a-vis, axial line are coaxial, so
After to translate them opposite close, the rotation in translation motion adjusts the relative position of the two, makes the spiral of two spiral coils
Coiling circle 2 terminations alignment continues through rotation in the gap 3 between the adjoining spiral coiling circle 2 on three spiral coils
Their nestings are combined into one by the mode of propulsion；
3rd, two spiral coils and three spiral coil nestings carry out shaping after combining, and make the two keep concordant, i.e.,
Make large-scale five spiral coils of Fig. 1.
