Description

Technical Field

[0001] The utility model relates to the technical field of flour production devices, in particular to a rotary vibrating screen for flour production. Background Art

[0002] The rotary vibrating screen is a high-precision fine powder screening machine produced by Xinxiang Weimeng. It has low noise, high efficiency, and can quickly change the screen in 3-5 minutes. It is suitable for screening and filtering of materials such as particles, powders, and mucus. The rotary vibrating screen uses an upright motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface. By adjusting the phase angle at the upper and lower ends, the motion trajectory of the material on the screen surface can be changed.

[0003] At present, the existing utility model provides a powder rotary vibrating screen, and a feeding hopper and a feeding port are set, so that the waste enters the interior of the conveying pipe through the feeding hopper, and cooperates with the set motor and conveying assembly to allow the material to enter the feed port through the discharge elbow and enter the interior of the rotary vibrating screen body, thereby facilitating the transportation of the waste from a low place to a high place, effectively reducing work fatigue, and at the same time, the waste can be evenly transported through the set rotating blades, avoiding the rotary vibrating screening effect being affected to a certain extent due to excessive dumping of waste, further improving the screening quality, and being more convenient to use and operate.

[0004] For example, a powder rotary vibrating screen disclosed in the authorization number CN218424059U includes a rotary vibrating screen body, a feed port is provided on the top of the rotary vibrating screen body, a block is fixedly installed in the middle of one side of the rotary vibrating screen body, a fixed plate is connected to the outside of the block, a conveying pipe is fixedly installed inside the fixed plate, a conveying assembly is provided inside the conveying pipe, the conveying assembly includes a roller and a plurality of rotating blades, the roller is rotatably connected to the middle of the top of the inner wall of the conveying pipe, a plurality of rotating blades are evenly fixedly installed on the surface of the roller, a motor is fixedly installed in the middle of the bottom end of the conveying pipe, the transmission shaft of the motor passes through the conveying pipe and is fixedly connected to the bottom end of the roller, a feeding port is opened at the bottom of one side of the conveying pipe, and a feeding hopper is fixedly installed on the surface of the feeding port. However, such a powder rotary vibrating screen will cause dust to float outward when the rotary vibrating screen vibrates, and the operator inhaling dust is harmful to health.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that when the rotary vibrating screen vibrates, dust will be scattered outward, and the operator will inhale the dust, which is harmful to health. Therefore, it is necessary to improve the existing technology. Utility Model Content
