In order to further reduce the external air from entering the first water outlet pipe 33, a one-way valve 6 is disposed at one end of the first water outlet pipe 33 close to the steam distributor 3, and the condensed water in the steam distributor 3 can be discharged from the one-way valve 6, so that the external air is difficult to enter the steam distributor 3 from the one-way valve 6.

Referring to fig. 2, every two adjacent steam distributors 3 are arranged as a group, two steam inlet pipes 32 in a group of steam distributors 3 are oppositely connected with steam pipes 51, a four-way pipe 5 is connected between the two steam pipes 51, two openings of the four-way pipe 5 in the depth direction of the water tank 4 are respectively arranged as a water outlet end 52 and a steam inlet end 55, the water outlet end 52 is one end of the four-way pipe 5 close to the water tank 4, the steam inlet end 55 is one end of the four-way pipe 5 far away from the water outlet end 52, a second water outlet pipe 53 is connected at the water outlet end 52, the second water outlet pipe 53 extends to the bottom of the water tank 4, and the steam inlet end 55 is connected with a main steam inlet pipe 54. When steam entering the main steam inlet pipe 54 enters the steam pipeline 51 through the four-way pipe 5, hot steam is easy to condense into water when encountering the cold steam pipeline 51, the second water outlet pipe 53 is arranged, the condensed water can be discharged into the water tank 4 from the second water outlet pipe 53, and therefore the condensed water can be reduced from entering the steam inlet pipe 32. In order to make it difficult for the water condensed in the steam pipe 51 to flow into the steam inlet pipe 32 and to directly flow into the water tank 4 from the second water outlet pipe 53, the steam pipe 51 is connected obliquely between the cross pipe 5 and the steam inlet pipe 32, in order to facilitate the connection between the steam inlet pipe 32 and the steam pipe 51, the steam pipe 51 is configured as an S-shaped pipe, and the height of one end of the steam pipe 51 close to the steam inlet pipe 32 from the water tank 4 is 0.6 to 0.7 times the height of one end of the steam pipe 51 close to the cross pipe 5 from the water tank 4, in one embodiment, preferably, the height of one end of the steam pipe 51 close to the steam inlet pipe 32 from the water tank 4 is 0.6 times the height of one end of the steam pipe 51 close to the cross pipe 5 from the water tank 4, on the one hand, the connection between the steam inlet pipe 32 and the steam pipe 51 can be facilitated, on the other hand, the condensed water above the steam pipe 51 can be discharged into the, thereby reducing the ingress of condensed water into the steam inlet pipe 32.

Referring to fig. 3, although the water condensed on the steam pipe 51 can directly enter the second water outlet pipe 53 and be discharged into the water tank 4, when the steam enters the steam distributor 3 from the steam inlet pipe 32, the hot steam still condenses into water when encountering the cold steam distributor 3 or the cold steam inlet pipe 32, and therefore, the side surfaces of the steam distributor 3 at the two sides of the steam inlet pipe 32 are both provided with the first inclined surfaces 34, and the condensed water can flow to the steam distributor 3 from the first inclined surfaces 34, then enters the first water outlet pipe 33, and flows into the water tank 4 through the first water outlet pipe 33. In order to make the condensed water generated in the steam inlet pipe 32 not easily drop on the copper wire, a plurality of flow deflectors 37 are arranged at one end of the steam inlet pipe 32 extending into the steam distributor 3, the flow deflectors 37 are all arranged in an inclined manner, one ends of the flow deflectors 37 far away from the steam inlet pipe 32 are respectively abutted to the side walls of the corresponding positions of the steam distributor 3, one ends of the flow deflectors 37 far away from the steam inlet pipe 32 are provided with flow guide inclined planes 36, the flow guide inclined planes 36 are arranged in an inclined manner towards the first inclined planes 34, and the flow guide inclined planes 36 can enable the condensed water on the flow deflectors 37 to be transited to the first inclined planes 34. The condensed water falls down to the first inclined plane 34 along the inclined direction of the guide vane 37, and the condensed water falls down to the first water outlet pipe 33 through the first inclined plane 34. In order to more rapidly discharge the condensed water falling from the first slope 34 into the water tank 4, the sides of the steam distributor 3 located at both sides of the first water outlet pipe 33 are provided with second slopes 35 (as shown in fig. 2). The condensed water can flow through the first slope 34 to the second slope 35 and then from the second slope 35 into the first outlet pipe 33 and then through the first outlet pipe 33 into the sump 4.

In order to enable the first water outlet pipe 33 and the second water outlet pipe 53 to form a water seal in the water tank 4, the distance from one end of the first water outlet pipe 33 far away from the steam distributor 3 to the bottom of the water tank 4 is 0.1-0.15 times of the depth of the water tank 4, and the distance from one end of the overflow pipe 41 extending into the water tank 4 to the bottom of the water tank 4 is 0.7-0.8 times of the depth of the water tank 4. In one embodiment, preferably, the distance from one end of the first water outlet pipe 33 away from the steam distributor 3 to the bottom of the water tank 4 is 0.1 times the depth of the water tank 4, and the distance from one end of the overflow pipe 41 extending into the water tank 4 to the bottom of the water tank 4 is 0.8 times the depth of the water tank 4, so that a water sealing effect can be further achieved between the first water outlet pipe 33 and the water tank 4, and external air can hardly enter the steam distributor 3. When high-pressure steam was discharged from copper wire outlet 31, the temperature of steam was still higher, consequently the equal vertical baffle 42 that is provided with in the edge of basin 4 near the one side of steam distributor 3, baffle 42 can play the effect of protection for reduce the production of staff potential safety hazard in the course of the work, baffle 42 end to end connects around forming a protective housing 43, and a plurality of steam distributor 3 all are located protective housing 43.

The implementation principle of the above embodiment is as follows: when the copper wire is annealed, the temperature is increased, and the surface of the copper wire is easily oxidized when meeting air, so that the copper wire needs to be isolated from the air. First, water is filled in the water tank 4, the first water outlet pipe 33 and the second water outlet pipe 53 extend into the water tank 4, and water in the water tank 4 enables the first water outlet pipe 33 and the second water outlet pipe 53 to form water seal, so that outside air is not easy to enter the steam distributor 3 from the first water outlet pipe 33 and the second water outlet pipe 53. Then high-pressure steam is introduced into the steam inlet end 55 of the four-way pipe 5, the high-pressure steam enters the steam distributor 3 from the steam inlet pipe 32, the steam entering the steam distributor 3 enters the copper wire placing pipe 2, and the steam entering the steam distributor 3 discharges the air inside the copper wire placing pipe 2, so that oxygen does not exist in the copper wire placing pipe 2. The steam introduced into the interior of the steam distributor 3 is also discharged from the copper wire outlet 31, thereby making it difficult for outside air to enter the steam distributor 3 from the copper wire outlet 31. When the high-pressure steam enters the four-way pipe 5 and the steam distributor 3, condensed water is easily generated, and the condensed water on the steam pipeline 51 is discharged into the water tank 4 through the second water outlet pipe 53. The condensed water located in the steam distributor 3 flows to the second slope 35 through the first slope 34, then flows to the first outlet pipe 33 through the second slope 35, and then is discharged from the first outlet pipe 33 into the water tank 4.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
