[0029] The working principle of the converter air intake regulating device for vinyl chloride conversion provided by the utility model is as follows:

[0030] First, vinyl chloride gas enters the converter 2 through the intake pipe 1; the interior of the intake pipe 1 is designed as a turbulent flow area and a flat flow area to accommodate vinyl chloride gas with different flow rates;

[0031] Inside the air intake pipe 1, the conical block 3 plays a key role; the conical block 3 changes the flow area of ​​the air intake pipe 1 by sliding on the inner wall of the air intake pipe 1, thereby adjusting the air intake amount; the sliding of the conical block 3 is controlled by the trapezoidal block 5; the inclined surface of the trapezoidal block 5 is installed in cooperation with the back of the conical block 3, and when the trapezoidal block 5 moves up and down, it pushes the conical block 3 to slide along the inner wall of the air intake pipe 1 through the inclined surface;

[0032] The up and down movement of the trapezoidal block 5 is achieved by rotating the threaded rod 51; the threaded rod 51 is threadedly connected to the air intake pipe 1, so when the threaded rod 51 rotates, it moves up and down along the axis of the air intake pipe 1, thereby driving the trapezoidal block 5 to move;

[0034] In addition, in order to improve the sliding stability of the conical block 3, a push rod 7 and a slide groove 13 are provided; one end of the push rod 7 is fixedly connected to the conical block 3, and the other end is slidably connected to the slide groove 13 on the inner wall of the intake pipe 1 through a cross-shaped slide rod 12; this design can ensure that the conical block 3 maintains a stable trajectory and posture during the sliding process;

[0035] Finally, the sealing rings 11 equidistantly arranged on the inner wall of the slope 4 can enhance the sealing performance between the conical block 3 and the slope 4 to prevent the leakage of vinyl chloride gas;

[0036] In summary, the utility model realizes the precise regulation of the air intake amount of the converter for vinyl chloride conversion through the interaction of the conical block 3, the trapezoidal block 5, the threaded rod 51 and the limiting structure; at the same time, the sliding stability of the conical block 3 is improved through the design of the top rod 7 and the slide groove 13, and the sealing performance is enhanced by the sealing ring 11.
