By introducing processor control technology, more accurate amplitude and higher precision screening can be achieved, which greatly improves screening efficiency and product quality. However, in the existing rotary vibrating screen, it is necessary to stop the machine during the re-discharging process, open the discharge door on the discharge port and manually discharge the screened material, which makes the screen of the rotary vibrating screen wear and damage very quickly. In addition, most of the existing discharge doors use hinged inward or outward door technology, which makes the discharge door and the fine powder screen not tightly closed, which will cause powder leakage during the re-screening process and unclean discharge. At the same time, the wear and sagging of the hinges may also cause the screen to be damaged, seriously affecting the effectiveness of the screening process. Summary of the invention

The length of the lower screen frame mounting portion protruding toward the inner wall of the frame is greater than the inner wall size of the upper frame. The protruding mesh flange screen hoop adopts an annular cylindrical structural design. Therefore, the contact part between the protruding mesh flange screen hoop and the screen is also an arc structure, so that the screen does not contact the angled The sharp parts will generate vibration during the operation of the ternary rotary vibration equipment.

Since the mesh height of the screen is not lower than the height of the bottom of the discharge porch, the powder on the screen will enter the discharge porch during the rotary vibration process, but the discharge port at the end of the discharge porch The material in the discharge porch will return to the mesh surface for further screening under the action of the horizontal and vertical amplitudes of the vibrating screen until the powder is completely screened and discharged through the discharge port. The design of the discharge porch and its height design can effectively avoid the need to open a discharge door on the side wall of the screen frame. If a discharge door is opened on the side wall, the discharge door cannot be completely fitted with the side wall of the screen frame, resulting in serious material leakage during the screening process. The opening and closing of the discharge door will also cause wear on the screen, reducing the service life of the screen. In addition, the screened material is incomplete and the discharge is unclean.

A valve body sealing ring is also provided in the circle of the valve body that fits the valve plate, so that the sealing of the valve body on the discharge port is better, and the sieved material will not leak out of the discharge port during the screening process. The design of the butterfly valve structure allows its operation to be realized in a variety of ways such as manual, electric, and pneumatic, so that the automatic discharge door of the vibrating screen can be better remotely controlled and automatically operated.
