[0034] More preferably, the spherical concave head adopts a hollow trumpet-shaped structure; the spherical convex head adopts a hollow boss-shaped structure, and the shape of the boss-shaped structure is adapted to the inner cavity of the trumpet-shaped structure. When the boss-shaped structure is located in the trumpet-shaped structure, the outer wall of the boss-shaped structure fits with the inner wall of the trumpet-shaped structure.

[0035] A ball head rubber pad is also provided in the trumpet-shaped structure, and when the boss-shaped structure is located in the trumpet-shaped structure, it is used to seal the two. That is, liquid leakage between the boss-shaped structure and the inner wall of the trumpet-shaped structure is prevented.

The locking device adopts a horizontal locking type quick clamp; when the spherical convex head is located in the spherical concave head, the horizontal locking type quick clamp is pressed against the outer wall of the spherical concave head.

[0036] Combined with the accompanying drawings and technical solutions, the use process of the utility model is described as follows:

[0037] like Figure 1 As shown, the movable furnace door 2 can move relative to the fixed furnace body 1; one end of the ball head quick connect joint 10 is connected to the fixed water inlet pipe group 13 and the fixed water return pipe group 3, and the other end is connected to the movable water inlet pipe group 9 and the movable water return pipe group 5. When the movable furnace door 2 is docked with the fixed furnace body 1, both ends of the ball head quick connect joint 10 are in a connected state, and when the movable furnace door 2 is separated from the fixed furnace body 1, both ends of the ball head quick connect joint 10 are in a disconnected state.

[0038] like Figure 2 , 3As shown, the fixed water inlet pipe group 13 and the fixed water return pipe group 3 include multiple water pipes, which supply water to the cooling bed, the crystallizer and the furnace door respectively. Each water pipe includes a fixed butterfly valve 12 and a fixed ball valve 11; the fixed butterfly valve 12 is located at the low point and can control the on-off of the pipeline; the fixed ball valve 11 is located at the pipeline side interface, which is higher than the fixed butterfly valve 12 and lower than the spherical convex head pipe 17, and can discharge the residual water in the pipeline. When smelting, the fixed butterfly valve 12 is opened and the fixed ball valve 11 is closed.

[0039] like Figure 2 , 3 As shown, the movable water inlet pipe group 9 and the movable water return pipe group 5 include multiple water pipes, each of which includes a movable butterfly valve 7, an air suction valve 8 and a pressure ball valve 6. The movable butterfly valve 7 is flush with the pipeline and can control the on and off of the pipeline; the air suction valve 8 and the pressure ball valve 6 are both located at the high point of the pipeline branch.

[0040] During smelting, open the movable butterfly valve 7 and close the pressure ball valve 6. Before opening the furnace door after smelting, keep the locking device 16 in a locked state, close the fixed butterfly valve 12 and the movable butterfly valve 7, open the fixed ball valve 11, and then the suction valve 8 automatically inhales air, and the residual water in the pipeline closed by the butterfly valve is discharged through the fixed ball valve 11. The furnace is opened after the water is drained.

[0041] The utility model saves space: If the electron beam melting furnace door uses the traditional hose to supply water, it will occupy a lot of space above the ground, affecting the furnace cleaning and maintenance work. The utility model uses a separate hard pipe water supply pipeline. Only the necessary pipe joints need to be set above the ground to supply water to the furnace door, cooling bed and crystallizer at the same time, saving a lot of space;

[0042] The utility model is convenient and fast for waterway docking, with high reliability: the mobile and fixed ends use special ball head quick connectors, which are equipped with special spherical rubber pads for sealing, and are connected in series with bellows to compensate for deviations. Compared with standard flat waterway quick connectors, this spherical connector does not require manual adjustment, and can automatically complete the simultaneous docking of multiple connectors by a rail car. The spherical design and bellows can ensure self-alignment under certain deviations, and the connection is reliable and leak-proof;

[0043] The utility model is convenient for users to maintain: the movable end and the fixed end of the water channel are equipped with isolation butterfly valves. Before opening the furnace, the quick-connect joint can be cut off from the water supply end and the external water source end respectively. At this time, the fixed ball valve is opened, and the air intake valve automatically inhales air to balance the air pressure. The residual water in the pipeline between the isolation butterfly valves can automatically flow out from the ball valve, and the rear end of the ball valve can be connected to the sewage system according to the customer's on-site conditions. This design avoids the waste caused by the outflow of water in the furnace door, cooling bed, and crystallizer, and avoids the turbulent splashing of the residual water in the pipeline caused by directly separating the quick-connect joint; in addition, a pressure ball valve is set at the high point of the movable pipeline, which is closed daily. When necessary, it can be conveniently connected to the gas circuit for local pressure testing and leak detection, which is convenient for users to maintain the equipment.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. Therefore, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope defined by the claims of the present invention.
