A tube coiler and method for coiling a separation column

Abstract

The invention discloses a pipe winding machine for winding separation columns and a method. The pipe winding machine comprises a rack and further comprises winding modules, a drive device, a guide shaft and a guide wheel. A rotary shaft is arranged on the rack. The winding modules are rotatably connected to the rotary shaft and each comprises a sleeve and a first clamping opening. A hollow straight pipe is wound around the side wall of each sleeve. Each first clamping opening is used for fixing one end of the corresponding hollow straight pipe. The first clamping openings are formed in the side walls of the corresponding sleeve. The drive device is connected with the winding modules and drives the winding modules to rotate around the rotary shaft. The guide shaft is fixedly arranged relative to the rotary shaft. The guide wheel is slidably arranged on the guide shaft and rotates around the guide shaft. A guide groove is formed in the guide wheel. The guide groove is matched with the hollow straight pipes. By the adoption of the pipe winding machine, the problems that an existing winding machine only can achieve one circle of winding, and spiral pipes cannot be wound; and an existing spring coiling machine can wind spiral objects, but wound products rebound seriously, and adjacent two coils of circular rings cannot be tightly arranged in the prior art can be solved effectively. Meanwhile, the pipe winding machine is simple in structure, easy and convenient to operate and low in cost.

Description

technical field [0001] The invention relates to the field of machining, in particular to a pipe coiling machine and method for coiling a separation column. Background technique [0002] Nuclear fusion reactors use deuterium-tritium as nuclear fuel, so hydrogen isotope separation is one of the core technologies of the fusion reactor nuclear fuel cycle. The effective control of the environmental release of tritium during the operation of the reactor can also be applied to the multiplication and extraction of tritium, plasma discharge and treatment, etc. [0003] When using low-temperature chromatographic hydrogen isotope separation (GC) or palladium heat displacement chromatography hydrogen isotope separation to separate a large amount of hydrogen isotopes, it is necessary to fill the hollow straight tube with molecular sieve material or palladium material to form a separation column, and the separation column is cooled to reduce the temperature. Molecular sieve materials or ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the existing coiling machine in the prior art that can only roll a circle of hollow straight tubes, and cannot roll it into a spiral tube. Although the existing coiling machine can roll a spiral Shaped objects, but its function and structure are designed taking into account the characteristics of the rolled product, that is, the spring. The rolled product has elasticity and severe rebound, and it is impossible to make the two adjacent rings of the spiral object tightly In view of the above-mentioned deficiencies of the arrangement, a coiler and method for coiling a separation column are provided
