Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a novel vibrating circular screen. Background Technology

[0002] The vibrating circular screen is a high-efficiency screening device, mainly used for screening, grading, and removing impurities from granular materials. It employs rotary vibration combined with dynamic screen cleaning technology, making it suitable for industries such as chemical, food, pharmaceutical, and metallurgy, and especially ideal for scenarios requiring high-precision screening and prone to clogging.

[0003] Traditional vibrating circular screens mostly use fixed screens or a single vibration mode, which suffers from problems such as easy screen clogging, low screening efficiency, and excessive material residue. In existing technologies, some screening equipment improves screening efficiency by adding a rotating mechanism, but large particles can still clog the screen holes during use. Therefore, there is an urgent need for a new type of vibrating circular screen with a simple structure and high screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel vibrating circular screen to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A novel vibrating circular screen includes a vibrating circular screen body, within which a rotating mechanism and a screen are disposed. The rotating mechanism includes a rotating shaft and a stirring paddle. The rotating shaft is distributed along the axial direction of the vibrating circular screen body, and the stirring paddle is fixedly connected to the outer periphery of the rotating shaft. Grooves are formed on the inner walls at both axial ends of the vibrating circular screen body, and the screen is rotatably connected within the grooves. The stirring paddle includes a connecting rod, a spring, and a first collision block. One end of the connecting rod is fixedly connected to the rotating shaft, the other end of the rotating shaft is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the first collision block. A second collision block is fixedly connected to the inner wall of the screen, and the first and second collision blocks are located on the same arc.

[0007] Furthermore, the vibrating circular screen body has a feed inlet at the top, a screening outlet at the bottom, and a discharge outlet at the tail end.

[0008] Furthermore, it also includes a frame and a power mechanism, with the vibrating circular screen body fixedly connected to the frame.

[0009] Furthermore, the power mechanism includes a drive motor, a drive wheel, a belt, and a driven wheel. The drive motor is fixedly connected to the frame, the drive wheel is fixedly connected to the power output end of the drive motor, the driven wheel is fixedly connected to one end of the rotating shaft, and the drive wheel and the driven wheel are connected by belt drive.

[0010] Furthermore, a rubber layer is fixedly connected to the surface of both the first and second collision blocks.

[0011] The beneficial effects are:

[0012] This invention uses a rotating mechanism to drive the stirring paddle to rotate, which pushes the material to be evenly dispersed and pass through the screen, thereby improving the screening efficiency. While the stirring paddle is rotating, the first collision block of the stirring paddle periodically impacts the second collision block of the screen, causing the screen to vibrate and rotate, preventing blockage. When the first collision block periodically impacts the second collision block of the screen, the rubber layer reduces wear and noise. The overall structure is simple and reliable, and is suitable for industrial production. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] See Figures 1-4 As shown, this utility model provides a novel vibrating circular screen, including a vibrating circular screen body 1, which is fixedly connected to a frame 4; the top of the vibrating circular screen body 1 has a feed inlet 11, the bottom of the vibrating circular screen body 1 has a screening inlet 12, and the tail end of the vibrating circular screen body 1 has a discharge outlet 13; the vibrating circular screen body 1 is provided with a rotating mechanism and a screen 3, the rotating mechanism stirs the material in the vibrating circular screen body 1, and the stirred material is screened and classified by the screen 3, the rotating mechanism includes a rotating shaft 21 and a stirring paddle 22, the rotating mechanism is driven by a power mechanism to rotate in the vibrating circular screen body 1; the power mechanism includes a drive motor 51, a drive wheel 52, a belt 53, and a driven wheel 54, the drive motor 51 is fixedly connected to the frame 4, the drive wheel 52 is fixedly connected to the power output end of the drive motor 51, the driven wheel 54 is fixedly connected to one end of the rotating shaft 21, and the drive wheel 52 and the driven wheel 54 are connected by a belt 53.

[0021] During operation, the active motor 51 drives the active wheel 52 to rotate, and the active wheel 52 drives the driven wheel 54 to rotate via the belt 53. The driven wheel 54 drives the rotating shaft 21 to rotate, thereby enabling the stirring paddle 22 to stir the material and the screen 3 to complete the screening.

[0022] In this embodiment, the rotating shaft 21 is distributed along the axial direction of the vibrating circular screen body 1, and the stirring paddle 22 is fixedly connected to the outer periphery of the rotating shaft 21; the inner walls of the two axial ends of the vibrating circular screen body 1 are provided with roller grooves 23, and the screen 3 is rotatably connected in the roller grooves 23.

[0023] To improve the sorting effect, in this embodiment, the stirring paddle 22 includes a connecting rod 221, a spring 222, and a first collision block 223. One end of the connecting rod 221 is fixedly connected to the rotating shaft 21, the other end of the rotating shaft 21 is fixedly connected to one end of the spring 222, and the other end of the spring 222 is fixedly connected to the first collision block 223. A second collision block 31 is fixedly connected to the inner wall of the screen 3, and the first collision block 223 and the second collision block 31 are located on the same arc.

[0024] When the stirring paddle 22 rotates, the connecting rod 221 drives the first collision block 223 to rotate. Since the first collision block 223 and the second collision block 31 are located on the same arc, the first collision block 223 will collide with the second collision block 31 when it rotates, which can bring about the following effects:

[0025] First, a certain amount of kinetic energy can be applied to the second collision block 31, which can cause the second collision block 31 to drive the screen 3 to rotate slightly, so that the material at the bottom of the screen 3 moves, improving the screening effect. After the kinetic energy is applied, the screen 3 will also vibrate slightly, further improving the screening effect.

[0026] In this embodiment, a rubber layer is fixedly connected to the surface of both the first collision block 223 and the second collision block 31. When the first collision block periodically impacts the second collision block of the screen, the rubber layer reduces wear and noise.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
