[0002] In the existing technology, the baffles of the rapid cooling section of the JCF alloying furnace generally do not have the function of automatically adjusting the baffle opening. The opening of the baffles needs to be manually controlled, which is time-consuming and labor-intensive, and also inconvenient for operators to debug and maintain the equipment. Therefore, there is an urgent need to design an automatic adjustment device for the baffles of the rapid cooling section of the JCF alloying furnace. Summary of the Invention

[0021] The technical solution of the present invention will be specifically described below with reference to the accompanying drawings. The detailed features and advantages of the present invention are described in detail in the specific embodiments. The content is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Based on the specification, claims and drawings disclosed in this specification, those skilled in the art can easily understand the related objects and advantages of the present invention.

[0022] Figure 1This invention shows a paired assembly diagram of the automatic baffle adjustment device for the rapid cooling section of the alloying furnace JCF according to the present invention; Figure 2 The diagram shown is a schematic representation of the disassembled structure of the present invention after removing the handwheel handle; Figure 3 yes Figure 2 A front view of the structure; Figure 4 The internal structure diagram of the automatic adjustment device for the baffle of the rapid cooling section of the alloying furnace JCF is shown.

[0023] An automatic adjustment device for the baffle of the rapid cooling section of an alloying furnace JCF is specifically as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a base plate 9, an electric actuator 1, an electric actuator frame 2, and a baffle 3. The electric actuator 1, the electric actuator frame 2, and the baffle 3 are vertically installed on the base plate 9 from top to bottom. The bottom end of the electric actuator 1 passes through the electric actuator frame 2 via a bushing 4 and is connected to an adapter sleeve 5. The bottom end of the adapter sleeve 5 is provided with a valve stem 6. The electric actuator 1 has a rotating shaft inside, and the bushing 4 is sleeved on the outside of the rotating shaft. In addition, a handwheel handle 8 is installed on the outside of the electric actuator 1. The handwheel handle 8 is connected to the rotating shaft for transmission and can be manually adjusted by the handwheel handle 8.

[0024] The electric actuator frame 2 is fixedly mounted on the top of the baffle 3 with screws. The bushing 4 is sleeved on one end of the adapter sleeve 5, and the other end of the adapter sleeve 5 is keyed to the valve stem 6. The baffle 3 has a through hole through which the valve stem 6 passes, and the bottom of the valve stem 6 is fixedly connected to the base plate 9.

[0025] The bushing 4 and the adapter sleeve 5 are fitted together through a square hole. A flat key 7 is inserted inside the adapter sleeve 5, and the adapter sleeve 5 is clamped and fixed to the valve stem 6 by the flat key 7, as detailed below. Figure 5 , Figure 6 , Figure 7 As shown, the bushing 4 and the electric actuator frame 2 are fixedly connected, and the electric actuator 1 drives the valve stem 6 to rotate through the bushing 4 and the adapter sleeve 5.

[0026] The working principle of the automatic baffle adjustment device for the rapid cooling section of the JCF alloying furnace is as follows:

[0027] The automatic adjustment device for the baffle of the fast cooling section of the alloying furnace JCF has two working modes: manual mode and automatic mode. The manual mode is activated by the transmission shaft in the handwheel handle 8 and the electric actuator 1. The handwheel handle 8 is rotated to drive the valve stem 6 to rotate through the bushing 4 and the adapter sleeve 5, thereby manually adjusting the baffle 3.

[0028] The JCF rapid cooling section baffle automatic adjustment device in this invention typically uses automatic mode. Its working principle in automatic mode is as follows:

[0029] After the electric actuator 1 is working, it drives the bushing 4 to rotate through the internal transmission shaft. Since the bushing 4 and the adapter sleeve 5 are connected by a square hole, the bushing 4 drives the adapter sleeve 5, and the adapter sleeve 5 drives the valve stem 6 to move. Since the baffle 3 and the electric actuator frame 2 are fixedly connected, and the electric actuator bracket 2 and the bushing 4 are fixed structures, the movement of the valve stem 6 can drive the movement of the baffle 3, automatically adjusting the opening of the baffle. This facilitates the debugging and maintenance by the staff and solves the technical problem that the baffle of the JCF fast cooling section cannot be automatically adjusted.

[0030] Finally, it should be noted that although the present invention has been described with reference to specific embodiments, those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Various equivalent changes or substitutions can be made without departing from the concept of the present invention. Therefore, any changes or modifications to the above embodiments within the essential spirit of the present invention will fall within the scope of the claims of the present invention.
