Description

Technical Field

[0001] This utility model belongs to the field of rotary vibrating screen technology, and in particular relates to a rotary vibrating screen that can uniformly distribute materials. Background Technology

[0002] A vibrating screen is a high-precision fine powder screening machine. It features low noise, high efficiency, and a fully enclosed structure, making it suitable for screening and filtering granular, powdery, and viscous materials. The vibrating screen uses a vertical motor as the excitation source, with eccentric weights installed at both the upper and lower ends of the motor. This converts the motor's rotational motion into a three-dimensional motion (horizontal, vertical, and inclined), which is then transmitted to the screen surface. Adjusting the phase angle at the upper and lower ends changes the trajectory of the material on the screen surface.

[0003] In existing vibrating screens, material tends to accumulate on the screen mesh during use, preventing the material from passing through quickly. Therefore, we propose a vibrating screen that can uniformly distribute material. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a vibrating screen that can uniformly distribute materials, thereby achieving uniform material distribution.

[0005] In view of this, the present invention provides a rotary vibrating screen capable of uniformly distributing materials, comprising a base, a vibration spring mounted on the top of the base, a bottom frame mounted on the top of the vibration spring, a bracket welded to the bottom edge of the bottom frame, an excitation motor mounted on the inner wall of the bracket, an excitation block mounted on the output end of the excitation motor, a rotary vibrating frame sealed to the top of the bottom frame, a ball-supporting frame welded to the inner wall of the rotary vibrating frame, a screen mounted on the outer wall of the ball-supporting frame, a connecting rope mounted on the inner wall of the ball-supporting frame, a bouncing ball sleeved on the outside of the connecting rope, a material distribution motor mounted at the bottom of the bottom frame, a rotating shaft mounted on the output end of the material distribution motor, a material distribution seat fixedly connected to the outer wall of the rotating shaft, a material distribution plate welded to the outer wall of the material distribution seat, a cover plate welded to the top of the rotary vibrating frame, a hopper welded to the top of the cover plate, and a discharge slot welded to the outer wall of the rotary vibrating frame.

[0006] Based on the above structure, the excitation motor drives the excitation block to rotate, which in turn drives the screen on the outer wall of the ball support frame to vibrate through the vibration spring. The screen screen is used to screen the material. At the same time, the distribution motor drives the distribution seat on the outer wall of the rotating shaft to rotate. The rotation of the distribution seat drives the distribution plate to rotate synchronously, thereby distributing the material on the screen and preventing material accumulation.

[0007] Preferably, there are two sets of excitation blocks, which are perpendicular to each other. In this embodiment, the excitation motor drives the excitation blocks to rotate, which in turn drives the screen on the outer wall of the ball support frame to vibrate through the vibration spring, and the material is screened through the screen.

[0008] Preferably, the ball-supporting frame is provided in two sets, and the two sets of ball-supporting frames are distributed parallel to each other and at equal intervals along the inner wall of the vibrating frame. In this embodiment, by providing two sets of ball-supporting frames, multi-stage screening of materials can be achieved.

[0009] Preferably, the bouncing balls are arranged in six groups, and the six groups of bouncing balls are distributed in a circle at equal angles about the center of the ball-supporting frame. In this embodiment, by setting six groups of bouncing balls, the vibration of the screen is driven by the connecting rope to make the bouncing balls vibrate, so that the vibration of the bouncing balls beats the screen, thereby clearing the material blocked inside the screen and greatly improving the screening efficiency of the screen.

[0010] Preferably, the material distribution plate is arc-shaped, and there are four sets of material distribution plates. The four sets of material distribution plates are distributed in a circle at equal angles about the central axis of the material distribution seat. In this embodiment, by setting the arc-shaped material distribution plates, the material distribution motor drives the material distribution seat on the outer wall of the rotating shaft to rotate, and the rotation of the material distribution seat drives the material distribution plate to rotate synchronously, thereby distributing the material on the screen.

[0011] Preferably, the material distribution seat is provided in two sets, and the material distribution plates on the outer walls of the two sets of material distribution seats are oriented in opposite directions. In this embodiment, by setting the material distribution plates in opposite directions, the material on the screen is not distributed and the material accumulation is avoided.

[0012] Preferably, three sets of feeding troughs are provided, and the three sets of feeding troughs are distributed parallel to each other and at equal intervals along the outer wall of the vibrating frame. In this embodiment, by providing three sets of feeding troughs, the orderly feeding operation of the screened material is achieved.

[0013] The beneficial effects of this utility model are: 1. This rotary vibrating screen, which can uniformly distribute materials, is equipped with a material distribution plate. The vibrating motor drives the vibrating block to rotate, which in turn drives the screen on the outer wall of the ball support frame to vibrate through the vibration spring. The material is then screened through the screen. At the same time, the material distribution motor drives the material distribution seat on the outer wall of the rotating shaft to rotate. The rotation of the material distribution seat drives the material distribution plate to rotate synchronously, thereby distributing the material on the screen and preventing material accumulation.

[0014] 2. This rotary vibrating screen, which can evenly distribute materials, uses a connecting rope. The vibration of the screen mesh drives the bouncing balls to vibrate through the connecting rope. The bouncing balls vibrate and beat the screen mesh, thereby clearing the material blocked inside the screen mesh. This greatly improves the screening efficiency of the screen mesh and at the same time prevents the bouncing balls from shifting, which would cause uneven cleaning of the screen mesh.

[0020] Based on the above structure, the excitation motor 5 drives the excitation block 501 to rotate, which in turn drives the screen 8 on the outer wall of the ball support frame 7 to vibrate through the vibration spring 2. The screen 8 is used to screen the material. At the same time, the distribution motor 11 drives the distribution seat 13 on the outer wall of the rotating shaft 12 to rotate. The rotation of the distribution seat 13 drives the distribution plate 14 to rotate synchronously, thereby distributing the material on the screen 8 and preventing material accumulation.

[0021] In one embodiment, two sets of excitation blocks 501 are provided, and the two sets of excitation blocks 501 are perpendicular to each other.

[0022] In this embodiment, the vibrating motor 5 drives the vibrating block 501 to rotate, which in turn drives the screen 8 on the outer wall of the ball support frame 7 to vibrate through the vibration spring 2, and the material is screened through the screen 8.

The material is then screened through the screen 8. At the same time, the distribution motor 11 drives the distribution seat 13 on the outer wall of the rotating shaft 12 to rotate. The rotation of the distribution seat 13 drives the distribution plate 14 to rotate synchronously, thereby distributing the material on the screen 8 and preventing material accumulation.

[0034] Finally, the vibration of the screen 8 drives the bouncing ball 10 to vibrate through the connecting rope 9, which in turn causes the bouncing ball 10 to beat the screen 8, thereby clearing the material blocked inside the screen 8 and greatly improving the screening efficiency of the screen 8.
