Description

Technical Field

[0001] This utility model relates to the technical field of cylindrical primary cleaning screen devices, specifically a high-efficiency cylindrical primary cleaning screen for raw materials. Background Technology

[0002] The raw material cylindrical primary cleaning screen is a device used for preliminary cleaning of various raw materials. It is widely used in the food and chemical industries, such as feed, oil, flour, rice milling, and grain storage.

[0003] Existing screening equipment typically uses a fixed installation method for the screening cylinder, with an adjustable tilt angle. This makes it difficult to adapt to materials with different physical properties. For high-moisture or viscous materials (such as grains harvested after rain or oil crops with a slurry surface), the fixed tilt angle causes the material to slide down quickly due to poor flowability. Fine particles cannot pass through the screen and are prone to sticking and clogging at the screen holes. This not only reduces screening accuracy but also requires frequent shutdowns to clean the screen, severely affecting production continuity. When processing loose and easily screenable materials (such as dry beans or powdery raw materials), the fixed angle cannot fully utilize the equipment's potential. The material stays in the screen cylinder for too long, extending the screening time and reducing the output per unit time. To address the shortcomings of existing technology, we propose a high-efficiency raw material cylindrical primary cleaning screen to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses a high-efficiency raw material cylindrical primary cleaning screen.

[0027] According to the appendix Figure 1-8As shown, the system includes a symmetrically arranged first support frame 1 and a symmetrically arranged second support frame 2. The two sets of first support frames 1 and two sets of second support frames 2 are fixedly connected by crossbars 3. A screening cylinder 4 is provided on the top of the first support frame 1 and the second support frame 2. The two ends of the screening cylinder 4 are the inlet and the outlet, respectively, for feeding and discharging materials. An installation cylinder 5 is sleeved on the outer peripheral wall of the screening cylinder 4. The bottom of the installation cylinder 5 is open. An angle adjustment component 6 is provided on the top of the first support frame 1 and the second support frame 2. The angle adjustment component 6 adjusts the tilt angle of the installation cylinder 5. A drive component 7 is provided inside the installation cylinder 5. The drive component 7 drives the screening cylinder 4 to rotate and is connected inside the installation cylinder 5. Before screening the material, the tilt angle of the installation cylinder 5 to the screening cylinder 4 can be adjusted by the angle adjustment component 6 according to the properties of the material to be screened, thereby meeting the screening needs of materials with different properties.

[0028] The installation cylinder 5 is equipped with a support assembly 8. Multiple sets of support assemblies 8 are equidistantly distributed along the length of the installation cylinder 5. The support assemblies 8 support the screening cylinder 4. When screening materials, the material to be screened is first added into the screening cylinder 4 through the feed inlet. With the cooperation of the drive assembly 7, the screening cylinder 4 can be driven to rotate inside the installation cylinder 5, thereby causing the guide plate 41 inside the screening cylinder 4 to rotate and drive the material to be continuously conveyed towards the drum outlet, realizing the continuous flow of material in the screening cylinder 4 and ensuring the continuity of screening operation. During the screening process, under the action of gravity, the particles in the material will generate different movement trajectories on the screening cylinder 4 according to their size and weight. Smaller particles can fall through the screen holes, while larger impurities are left on the screen. As the screening cylinder 4 rotates, they gradually move towards the impurity discharge port and are finally discharged through the discharge port. This cycle is repeated to screen the material.

[0029] The tops of the two sets of second support frames 2 are respectively fixedly installed with second hinge seats 21, and the bottom outer peripheral walls of the mounting cylinder 5 are fixedly installed with second connecting shafts 22. One end of the second connecting shaft 22 is rotatably connected to the second hinge seat 21. The bottom of the mounting cylinder 5 rotates around the second connecting shaft 22. When processing high humidity or viscous materials, the tilt angle can be reduced to prolong the contact time between the material and the screening cylinder 4, so that fine particles have a better chance to pass through the screen holes and improve the screening accuracy. When processing loose and easy-to-screen materials, such as raw materials with low impurity content and large particle size difference, the tilt angle can be increased to speed up the material passage speed and increase the throughput per unit time. Thus, the tilt angle of the screening cylinder 4 can be adjusted according to the properties of the material, so as to improve the screening efficiency while ensuring the screening quality of the material.

[0030] A guide plate 41 is fixedly installed on the inner circumferential wall of the screening cylinder 4. The guide plate 41 is spiral-shaped. The angle adjustment assembly 6 includes an adjustment cylinder 61, a first hinge seat 62, a first connecting shaft 63, and a guide rail 64. The adjustment cylinder 61 is fixedly installed on the top of the two sets of crossbars 3. The output end of the adjustment cylinder 61 is fixedly connected to the first hinge seat 62. When increasing the tilt angle of the screening cylinder 4 to screen easily screened materials, the two sets of adjustment cylinders 61 are activated, causing the first hinge seat 62 at the top of the adjustment cylinder 61 to push one end of the screening cylinder 4 upward. During the upward movement, one end of the first connecting shaft 63 slides along the guide rail 64, while the other end of the first connecting shaft 63 is rotatably connected to the first hinge seat 62, thereby enabling the adjustment of the tilt angle of the screening cylinder 4.

[0031] The guide rail 64 is fixedly installed on both sides of the outer peripheral wall at the front end of the mounting cylinder 5. One end of the first connecting shaft 63 is rotatably connected to the first hinge seat 62, and the other end is slidably connected to the guide rail 64 through the mounting plate. When the screening cylinder 4 is tilted, the bottom end of the screening cylinder 4 rotates around the two sets of second connecting shafts 22 as the axis, so that one end of the two sets of second connecting shafts 22 is rotatably connected to the two sets of second hinge seats 21 respectively. The drive assembly 7 includes a drive motor 71, a drive gear 72, and a drive gear ring 73. The drive motor 71 is fixedly installed on the outer wall at the front end of the mounting cylinder 5, and the drive gear ring 73 is fixedly sleeved on the screening cylinder. 4. The output end of the drive motor 71 is fixedly connected to the drive gear 72 on the outer peripheral wall of the front end. The drive gear 72 meshes with one side of the drive gear ring 73. By starting the drive motor 71, the drive motor 71 drives the drive gear 72 to rotate. Through the meshing action between the drive gear 72 and the drive gear ring 73, the screening cylinder 4 can be rotated inside the mounting cylinder 5. When the material enters the rotating screening cylinder 4, it is pushed towards the inner wall of the cylinder under the action of centrifugal force. At the same time, under the action of gravity, the particles in the material will generate different movement trajectories on the screen according to their size and weight. Smaller particles can fall through the screen holes, while larger impurities are left on the screen and gradually move towards the impurity discharge port as the screen cylinder rotates.

[0032] The support assembly 8 includes a support half-ring 81, a connecting ring 82, and a support rod 83. The support half-ring 81 is fixedly installed on the inner circumferential wall of the mounting cylinder 5. Multiple sets of support rods 83 are evenly distributed along the outer circumferential wall of the screening cylinder 4. The connecting ring 82 consists of a T-shaped ring 821 and a drive ring 822. The T-shaped ring 821 is rotatably connected inside the support half-ring 81, and the drive ring 822 rotates along the inner circumferential wall of the support half-ring 81. The T-shaped ring 821 and the drive ring 822 are fixedly connected. The two ends of the support rod 83 are fixedly connected to the drive ring 822 and the screening cylinder 4, respectively. When the screening cylinder 4 rotates, the multiple sets of support assemblies 8 can connect the screening cylinder 4 and the mounting cylinder 5, ensuring the stability of the connection between the screening cylinder 4 and the mounting cylinder 5 and improving the stability of the screening cylinder 4 during rotation.
