Technical Field

The utility model relates to the technical field of heating and drying equipment, in particular to a heat conduction oil drying cylinder with long service life.

Background

The heat conducting oil drying cylinder is a heating and drying device widely used in the industries of textile printing and dyeing coating and grinding tools and the like. In actual use, the problem of oil leakage of most stretching drying cylinders after two or three years of use is found, and the repairing cost is almost the same as the new manufacturing cost. As shown in fig. 1, which is a cut-away view of the existing drying cylinder, the internal structure of the drying cylinder is unreasonable, when hot oil enters from a shaft head 1 and flows into an interlayer between an outer cylinder 4 and an inner cylinder 6 through a connecting pipe 5, the connecting pipe 5 is rapidly heated and expanded, and the head plate 2 is slowly heated and expanded to be inconsistent with the expansion of the connecting pipe 5, so that stress damage is generated to a welding seam, and the welding seams at two ends of the connecting pipe 5 are cracked and leaked oil after a long time; in the rotary work of the stretching drying cylinder, due to the combined action of the large tension of the cloth base wound on the roller surface and the gravity of the drying cylinder, the shaft head 1, the head plate 2 and the connecting pipe 5 are large in periodic deformation due to the fact that the head plate 2 is not evenly distributed with reinforcing ribs, and the connecting pipe 5 is enabled to leak oil due to fatigue cracks of welding seams at two ends of the connecting pipe 5. Therefore, the service life of the stretching drying cylinder is greatly reduced due to the superposition of dual factors of asynchronous heating expansion and rotation period deformation fatigue.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a heat conduction oil drying cylinder with long service life aiming at the defects of the prior art so as to solve the problem of short service life caused by asynchronous heating expansion and insufficient rigidity of the drying cylinder.

the utility model provides a long service life's a conduction oil dries by fire section of thick bamboo, includes the inner tube, the inner tube overcoat is equipped with the urceolus, the both ends welding of urceolus has outer shrouding, the both ends welding of inner tube has interior shrouding, be interior chamber in the inner tube, the intermediate layer between inner tube and the urceolus is for leading the grease chamber, the welding has the spindle nose on the outer shrouding at both ends respectively, wherein the center of one end spindle nose is equipped with the oil inlet, the center of other end spindle nose is equipped with the oil-out, the inner of spindle nose passes outer shrouding, and the end that passes is located between interior shrouding and the outer shrouding.

Preferably, a plurality of reinforcing ribs which are uniformly distributed are welded between the inner sealing plate and the outer sealing plate. Reinforcing ribs are added and uniformly distributed between the inner sealing plate and the outer sealing plate, so that the integral rigidity of the drying cylinder is greatly enhanced.

Preferably, the inner sealing plate is welded with a plurality of exhaust pipes, the outer ends of the exhaust pipes are welded with the outer sealing plate, and the inner cavity is communicated with the outside through the exhaust pipes. Along with the temperature rise, the air in the inner chamber expands and is exhausted through the exhaust pipe, so that the stress generated by expansion with heat and contraction with cold is reduced.

The utility model has the beneficial effects that: the original connecting pipe is replaced by the inner sealing plate, so that the temperature rise and expansion are synchronous, the welding seams at the two ends of the connecting pipe are prevented from cracking and leaking oil, and the service life is prolonged.
