[0065] like Figure 5 As shown, the utility model also provides a dephosphorization device, comprising:

[0066] A first support frame 1, wherein a conveying component 22 is disposed on the upper side of the first support frame 1;

[0067] A second support frame, the second support frame is arranged above the first support frame 1, and a telescopic component is arranged on the top of the second support frame;

[0068] In the above-mentioned spray structure, the fixed part of the spray structure is connected to the telescopic end of the telescopic part, and the periphery of the fixed part is connected to a protective shell 20, which is used to cover the outside of the continuous casting billet.

[0069] Specifically, the first support frame 1 is the frame of the dephosphorization device, and a conveying component 22 is arranged on the upper side of the frame. A plurality of leakage holes are arranged on the conveyor belt of the conveying component 22 for the water sprayed by the nozzle 19 to leak downward. The arrangement of the conveying component 22 can conveniently convey a plurality of continuous casting billets to the second support frame for dephosphorization spraying.

The fixed component is connected to the upper end of the protective shell 20, and the lower end of the protective shell 20 is open. Driven by the telescopic component, the fixed component and the protective shell 20 can be raised and lowered. When the continuous casting billet is conveyed into place, the telescopic component extends to drive the protective shell 20 to cover the continuous casting billet, and then the nozzle 19 sprays water to dephosphorize the continuous casting billet to prevent the sprayed water from splashing.

[0070] In this embodiment, the conveyor belt is a chain plate 23, and the telescopic component is a cylinder 17, a hydraulic cylinder or an electric telescopic rod.

[0071] In this embodiment, a bottom spring 21 is disposed at the lower end of the protective shell 20 for elastically contacting the chain plate 23 when the protective shell 20 descends.

[0072] In summary, when the dephosphorization device provided by the utility model is used, take the dephosphorization of a continuous casting billet as an example: when the external pipe 3 is connected to the fixed pipe 2, the external pipe 3 is inserted into the fixed pipe 2. Due to the effect of the external chamfer 8, multiple push rods 6 can be pushed outward with the insertion of the external pipe 3, and then the unlocking rod 5 is inserted into the guide groove 11, and the push rod 6 is inserted into the annular groove 10; then the push part is rotated, and the push rod 6 is pushed downward through the threaded fit, and the push rod 6 is used to drive the external pipe 3 to move downward, compressing the sealing ring 13, thereby completing the sealing connection process. When the sealed fixed connection between the external pipe 3 and the fixed pipe 2 is completed, the continuous casting billet is transported to the position below the protective shell 20 through the chain plate 23, and the protective shell 20 is driven by the cylinder 17 to be sleeved on the continuous casting billet, and then the continuous casting billet is sprayed with water through multiple nozzles 19, thereby completing the dephosphorization process; the water sprayed by the nozzle 19 flows out through the gap of the chain plate 23, thereby completing the use of the dephosphorization device.

[0073] When it is necessary to release the external tube and the fixed tube 2, first rotate the pushing part to move it upward, and then hold the external tube 3 on the anti-slip groove 169 and rotate it, so that the unlocking rod 5 moves outward with the movement of the guide groove 11. As the unlocking rod 5 expands outward, the push rod 6 also moves outward until the unlocking rod 5 is stuck in the positioning groove 12; at this time, the push rod 6 disengages from the annular groove 10 and pulls the external tube 3 outward, and the push rod 6 close to the sealing ring 13 contacts the outer wall of the external tube 3. At this time, the entire joint component is in a state of outward expansion until the external tube 3 is pulled out, thereby completing the operation of disconnecting the external tube 3 from the fixed tube 2.

[0074] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
