This invention relates to a cooling device for crosslinked pipes used when crosslinking pipes.

れを架橋管に導入して業橋・冷却し、しかるのちドラム
で巻とるようにしている。In the so-called catenary-type continuous cross-linking equipment and vertical-type continuous cross-linking equipment, an extruder extrudes the insulation coating on the outside of the cable core supplied from the supply drum, and then introduces it into the cross-linking pipe where it is bridged and cooled. , and then wind it up on a drum.

開放して必要な作業を行なうようにしてい、る。In the continuous cross-linking equipment described above, when reassembling work such as exchanging the product size, the heating of the cross-linked pipe is stopped and the cross-linked pipe is cooled to near room temperature, and then the inert gas and cooling medium inside the cross-linked pipe are removed. The pipe is removed and the upper part of the bridge pipe is opened to perform the necessary work.

°大きく、装置の稼動率も低下する。By the way, in order to cool the cross-linked pipe, a cooling method that raises the liquid level of the cooling medium in the pipe, a natural cooling method, etc. are generally adopted. Since the temperature of the cross-linked pipe is high immediately after the cross-linking, if the liquid level of the cooling medium is raised, it will evaporate, causing an abnormal increase in the internal pressure of the cross-linked pipe, and the cross-linked pipe will be rapidly cooled. There is a risk that the mechanical strength of the pipe will decrease and even cracks will occur.On the other hand, the latter natural cooling method takes a long time to cool down, resulting in a very large time loss and reducing the operating rate of the equipment. descend.

A damper is provided, and when the bridge pipe is cooled, each of the dampers is opened to force cooling air from the inlet to the flow path.

成されている。As shown in the figure, an outer cylinder 2 is fitted on the outside of a bridge pipe 1 into which the cable is introduced, and a cylindrical flow path 3 is formed between the two.
なお、架橋管１は、例えば加熱ヒータによって外部加熱
するようになっており、その放熱を防ぐため、前記外筒
２の外側に断熱材より成る保温層を設けることができる
。The cross-linked pipe 1 is designed to be externally heated, for example, by a heater, and in order to prevent heat radiation, a heat retaining layer made of a heat insulating material can be provided on the outside of the outer cylinder 2.

されるようになっている。An inlet 4 is formed at one end of the outer cylinder 2, and an outlet 5 is provided at the other end, and an inlet damper 6 and an outlet damper buff are attached to each of the inlet 4 and the outlet 5. There is. Each of these dampers 6.7 is kept closed when the cross-linked pipe 1 is heated, and is opened when the cross-linked pipe 1 is cooled, so that cooling air is forced through its population 4. .

る時間も短くて済み、稼動率を高めることかできる。As described above, this invention forms a cylindrical flow path on the outside over the entire length of the cross-linked pipe, and cross-links by forcing cooling air through the inlet provided at one end of this flow path. This system is designed to forcefully cool the pipes, and this cooling air is forced through to cool the crosslinked pipes to a certain temperature in a short period of time, and then the liquid level of the cooling medium inside the crosslinked pipes is raised to bring the crosslinked pipes to room temperature. By cooling the cross-linked pipe close to the base, the cross-linked pipe can be rapidly cooled within a range that does not reduce its mechanical strength, which shortens the overall cooling time and reduces the loss of cables consumed during cooling. . In addition, the time required to stop the equipment can be shortened, and the operating rate can be increased.

を挙げることができる。Furthermore, by providing opening/closing dampers at the inlet and outlet of the flow path, if each damper is closed, the inside of the flow path can be quickly disconnected from the outside air, thereby preventing heat radiation when heating the bridge pipe. This can be effective in maintaining the temperature of the crosslinked pipe.
