Description

Technical Field

[0001] This utility model relates to the field of rotary vibrating screen technology, specifically an ultrasonic rotary vibrating screen. Background Technology

[0002] A vibrating screen is a high-precision fine powder screening machine characterized by low noise and high efficiency. Its working principle involves using a vertical motor as the excitation source. Eccentric weights are installed at both ends of the motor, converting the motor's rotational motion into three-dimensional motion (horizontal, vertical, and inclined), which is then transmitted to the screen surface. This causes the material to move in an outward-expanding involute motion on the screen surface. The vibrating screen consists of a vertical motor, eccentric weights, and a screen surface. The eccentric weights at both ends of the motor convert the motor's rotational motion into three-dimensional motion. By adjusting the phase angle of the upper and lower ends, the trajectory of the material on the screen surface can be changed. Vibrating screens are suitable for screening and filtering granular, powdery, and viscous materials, and are widely used in the chemical, pharmaceutical, and food industries. For example, in the chemical industry, vibrating screens are commonly used for screening resins, coatings, and industrial pharmaceuticals; in the pharmaceutical industry, they are used for screening powders of active pharmaceutical ingredients.

[0003] Currently, the rotary vibrating screen equipment uses an open feed inlet at the top. The open feed inlet not only makes it inconvenient to control the feeding speed, but also causes airflow during the feeding process. The continuous feeding from a high position for a long time creates an impact inside the machine, which causes dust to overflow and spread from the feed inlet, polluting the environment and making it impractical.

A controllable feeding mechanism is provided on the feed inlet 5. A vibrating screen 6 is located inside the vibrating screen body 1. A discharge port 7 is located on one side of the vibrating screen body 1 above the vibrating screen 6. The vibrating screen body 1 is connected to the base 1 via a support rod 9. The frame 31 is equipped with a lifting machine 3, which is inclined. The upper end of the lifting machine 3 near the storage bin 2 is connected to the top of the storage bin 2 through a material guiding mechanism. A control panel 10 is provided on one side of the storage bin 2. The control panel 10 is electrically connected to the controllable feeding mechanism to realize the lifting and storage feeding of the ultrasonic rotary vibrating screen equipment. The high-level feeding is convenient and avoids dust overflow and pollution caused by feeding through the open feed port 5. The size of the feed port 5 is adjustable, that is, the feeding amount is controllable, and the feeding is precise, controllable and locked, so as to stabilize the feeding.

[0023] Specifically, the controllable feeding mechanism includes a feeding plate 51 and a servo motor 52. The feeding plate 51 is provided inside the feeding port 5. Both sides of the feeding plate 51 are connected to the feeding port 5 through connecting shafts. The servo motor 52 is mounted on one side of the feeding port 5 through a motor frame. The output end of the servo motor 52 is connected to the connecting shaft on one side of the feeding plate 51 through a coupling. A positioning mechanism is provided on the side of the feeding port 5 away from the servo motor 52. The servo motor 52 drives the feeding plate 51 to rotate inside the feeding port 5.

[0024] Furthermore, the positioning mechanism includes a positioning toothed disc 53, an electric telescopic rod 54, and a positioning rod 55. The positioning toothed disc 53 is located on the side of the feed inlet 5 away from the servo motor 52. The positioning toothed disc 53 is connected to the connecting shaft on one side of the feed plate 51. The lower end of the storage bin 2 above the positioning toothed disc 53 is provided with an electric telescopic rod 54. The output end of the bottom of the electric telescopic rod 54 is provided with a positioning rod 55. The positioning rod 55 is located above the positioning toothed disc 53. The electric telescopic rod 54 pushes the positioning rod 55 to move downward at the upper limit of the limiting plate 56. The lower end of the positioning rod 55 is inserted between the teeth of the positioning toothed disc 53. The positioning rod 55 positions and locks the positioning toothed disc 53, so that the feed plate 51 is positioned and locked in the feeding state of the feed inlet 5.

[0025] Furthermore, an angle sensor 57 is installed on the top of the feed plate 51 via a mounting slot. The output end of the angle sensor 57 is electrically connected to the input end of the control panel 10. The control panel 10 is electrically connected to the servo motor 52 and the electric telescopic rod 54. The angle sensor 57, the control panel 10, the servo motor 52, and the electric telescopic rod 54 are connected to the power supply via wires. The angle sensor 57 on the feed plate 51 detects the angle of rotation and tilt of the feed plate 51, that is, the size of the opening of the feed port 5. When the data detected by the angle sensor 57 is consistent with the input data, the angle sensor 57 transmits the data signal to the control panel 10. The control panel 10 controls the servo motor 52 to stop running and controls the electric telescopic rod 54 to run.

[0026] Furthermore, a limiting plate 56 is provided on one side of the feed inlet 5 between the electric telescopic rod 54 and the positioning toothed plate 53. The lower end of the positioning rod 55 is set in a V-shaped structure. The positioning rod 55 passes through the limiting hole and the limiting plate 56. The movement of the positioning rod 55 is limited on the limiting plate 56, making the positioning more secure.

[0027] Furthermore, the material guiding mechanism includes a material guide port 4 and a material discharge bag 41. A material guide port 4 is located on one side of the lifting machine 3 above the storage silo 2. The end of the material guide port 4 furthest from the lifting machine 3 is connected to the top of the storage silo 2 via the material discharge bag 41. The lifting machine 3 lifts and feeds material into the storage silo 2 through the material guide port 4 and the material discharge bag 41. The material discharge bag 41 can reduce vibration interference to the lifting machine 3.

[0028] Furthermore, the vibrating screen 6 inside the vibrating screen body 1 has two layers, and the discharge port 7 is set to correspond with the vibrating screen 6 for grading and screening.

[0029] The usage method of this embodiment is as follows: The material to be screened is lifted by the lifting machine 3 and transported to the storage bin 2 through the guide port 4 and the discharge bag 41. According to the operating requirements of the ultrasonic vibrating screen equipment, the control panel 10 is operated to input the opening data of the feed plate 51. The servo motor 52 drives the feed plate 51 to rotate in the feed port 5. The angle sensor 57 on the feed plate 51 detects the angle of rotation of the feed plate 51, that is, the size of the opening of the feed port 5. When the data detected by the angle sensor 57 is consistent with the input data, the angle sensor 57 transmits the data signal to the control panel 10. The control panel 10 controls the servo motor 52 to stop running. The electric telescopic rod 54 is operated, and the electric telescopic rod 54 pushes the positioning rod 55 to move downward at the upper limit of the limiting plate 56. The lower end of the positioning rod 55 is inserted between the teeth of the positioning toothed plate 53. The positioning rod 55 positions and locks the positioning toothed plate 53, so that the feeding plate 51 is positioned and locked in the feeding state of the feeding port 5. The material in the storage bin 2 enters the vibrating screen body 1 through the feeding port 5 and is screened by the vibrating screen 6. It is then screened and discharged through the discharge port 7, realizing the lifting and storage feeding of the ultrasonic vibrating screen equipment. The high-level feeding is convenient and avoids dust overflow and pollution caused by feeding through the open feeding port 5. The size of the feeding port 5 is adjustable, that is, the feeding amount is controllable, and the feeding is precise and controllable, making the feeding stable.
