ある。[Detailed description of the invention] The present invention relates to, for example, a cylinder drum for drying sizing warp yarns and a drying cylinder drum for woven fabric, paper, film, etc. provided in a warp sizing dryer, and is designed to uniformly heat this drying cylinder with thermal efficiency. This is an improved version.

の困難さなどがある、等である。 For example, in the warp sizing machine and the drying process of dyed cloth,
-24392 (the boiler is not shown), the cylinder is heated with heated steam generated by an externally installed boiler, and the warp and cloth wrapped around the cylinder are dried. The disadvantage of this method of heating the cylinder with steam is that it requires a lot of time (1 to 2 hours) and thermal energy for warming up before steam generation. Decreased thermal efficiency and increased operating costs due to steam leaks; repair costs and time required for steam leaks; increased fuel consumption due to low heat exchange efficiency; and large-scale boiler equipment and its management technology. These include the need for larger floor spaces due to larger equipment, and the difficulty of maintenance and inspection.

燥シリンダ加熱装置の開発が切望されている。 As described above, steam-type drying cylinder heating devices have many drawbacks, such as shortened warming-up time, low running costs, energy saving, labor saving, reduced equipment costs, and high thermal efficiency. There is a strong demand for the development of a dry cylinder heating device that satisfies this demand.
そこで、例えば実公昭56−55585（シリンダが乾

採用されにくい方式である。 Therefore, direct-fired gas burners such as Utility Model No. 56-55585 (in which the cylinder serves as a drying chamber) and Utility Model No. 55-52313 (a drum heater for paper drying in which the burner is replaced with a heater) are used. One possible method is to blow flame into the cylinder to heat it efficiently. However, with this method, not only the cylinder surface is not evenly heated, but also the warp, cloth, paper, etc.
This method is difficult to adopt because of the problem that if the rotation of the cylinder is stopped while it is being used as a drying cylinder for films, etc., the cylinder surface temperature will rise rapidly and the warp threads will be burned out.

利点がある。 That is, the cylinder heating device of the present invention uses a direct flame burner (an oil burner or a gas burner) as a heat source.
In order to heat the entire surface of the cylinder to a uniform temperature, the cylinder has a built-in annular boiler cylinder with a vacuum structure that generates steam using a burner. The heated steam generated in the boiler is sent into a drying cylinder with a vacuum structure to uniformly heat the cylinder, and the water condensed here is returned to the boiler using the rotational movement of the cylinder to be reheated. I made it.
This not only heats the cylinder quickly and evenly, but also allows the cylinder surface temperature to be controlled over a wide range of 60 to 160℃ due to the steam temperature in a vacuum. It has the advantage of

The water W is immediately turned into heated steam a, which is then sent to the drying cylinder 1 through the communication hole 13 b at the left end.
It runs widely in the space S of 0 and rapidly heats its entire surface at an even temperature. After heating, the steam decreases in temperature and condenses, forming a drain (water) at the bottom of the cylinder 10.
It is stored as D. This drain D is pumped up by the pumping vanes 15 as the cylinder 10 rotates clockwise, as shown in Figs . Collect,
The heat cycle of being reheated by burner B is repeated to produce heated steam a again.

多くの効果を発揮するものである。 When using the drying cylinder uniform heating device of the present invention, a ring-shaped annular boiler cylinder made of double cylinders is integrated into the shaft support cylinder in the drying cylinder, which is rotatably supported through the shaft support cylinders at both ends. The inside of the drying cylinder and the annular boiler cylinder are made into a vacuum structure in an airtight manner,
A burner (oil burner or gas burner) that sends a flame into the annular boiler cylinder is installed on one side of the shaft supporting cylinder, and the water accumulated at the bottom of the annular boiler cylinder is heated by the burner and the steam generated is transferred from the annular boiler cylinder. A communication hole for feeding into the drying cylinder is bored in the end face on the side opposite to the burner, and a communication gutter is installed in the cylinder on the burner side to return the drain (water) that condenses in the drying cylinder and accumulates at the bottom of the cylinder to the annular boiler cylinder. Since the end surface is arranged radially, a burner is used as the heating source, dramatically improving thermal efficiency.In addition, a small boiler (annular boiler) is built into the cylinder, which is heated by the burner to generate heated steam. By letting steam run widely through the small holes in the vacuumed drying cylinder, the cylinder surface is heated to a rapid and uniform temperature, and the surface temperature does not rise above the steam temperature, preventing condensation inside the cylinder. Since the waste drain is collected into the boiler using the rotation of the cylinder, running costs are low, and maintenance and inspection of the cylinder, burner, etc. can be facilitated. Due to its low equipment cost and compact size, it has excellent applicability as a cylinder for warp sizing dryers, fabric dyeing, paper, and film dryers.
