Description

Technical Field

[0001] This utility model relates to a vibrating screen, specifically a high-efficiency impurity removal device in the quinoa processing process. Background Technology

[0002] Quinoa vibrating screen impurity removal is a crucial step in quinoa processing. It utilizes the sieving principle of a vibrating screen to effectively separate impurities from the quinoa, thereby improving its purity and quality. The working principle of a quinoa vibrating screen is that it is driven by a motor, causing the screen body to vibrate at high frequency. This vibration causes the quinoa to jump and tumble on the screen surface. Simultaneously, the size of the screen openings separates impurities of different sizes from the quinoa. The vibrating screen effectively separates hard impurities such as stones, sand, and metal shavings, as well as lighter impurities such as dust and paper scraps, ensuring the purity of the quinoa. By adjusting the size of the screen openings, quinoa can also be graded to meet different particle size and quality requirements. When using a quinoa vibrating screen, it is necessary to regularly inspect and maintain the screen surface to ensure its flatness and integrity. Regular cleaning of the screen surface and openings is also required to prevent clogging and maintain sieving efficiency.

[0003] Utility model patent CN210171913U discloses a high-efficiency vibrating screen for quinoa processing, including a frame and a screen and cleaning mechanism installed inside the frame. A feed hopper is located at the top of the frame. A motor is installed on one side of the frame's exterior. Threaded rods are mounted on both sides of the frame's interior via bearings. A fixing plate is installed inside the frame via a sliding groove, and the fixing plate is connected to the threaded rods via threaded grooves. The cleaning mechanism consists of a cleaning chamber, an exhaust pipe, and a booster pump. The booster pump is installed outside the exhaust pipe, and the other end of the exhaust pipe is connected to the cleaning chamber. Cleaning rollers are mounted on both ends of the cleaning chamber via bearings. Limiting blocks are installed on both sides of the frame's interior, and two sets of support plates are installed inside each limiting block. This utility model effectively screens quinoa with high efficiency and facilitates quick cleaning of the screen surface, effectively ensuring screen cleanliness. The aforementioned equipment requires machine shutdown for cleaning and cannot effectively utilize the vibration generated by the vibrating screen. Furthermore, the threaded rods are located above the screen, making them susceptible to clogging by quinoa particles and other debris. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a highly efficient impurity removal device for quinoa processing.

[0005] To achieve the above objectives, this utility model provides a high-efficiency impurity removal device for quinoa processing, comprising a base and a sieve body elastically supported on the base. Baffles are provided on both sides of the sieve body, and a square frame plate for vibrating motors is fixed to the top of the baffles. Symmetrical vibrating motors are fixed to the surface of the square frame plate. Multiple screen structures are fixed within the openings on the surface of the sieve body. Each screen structure includes a quadrilateral screen fixing frame and square frame plates covering the upper and lower openings of the screen fixing frame. The opening of the upper square frame plate is covered with a screen, and multiple sets of symmetrical support bars are fixed to the upper two surfaces of the lower square frame plate. Two vibrating motors... The moving strips are connected and fixed together by multiple parallel brush strips to form a grid structure. The grid structure is installed in the screen fixing frame below the screen. The lower side of each moving strip is provided with the same number of top vibration spring fixing strips as the support strips. Every two mutually symmetrical support strips are located at the center between two mutually symmetrical top vibration spring fixing strips. Adjacent top vibration spring fixing strips and support strips are fixedly connected by vibration springs, so that the grid structure is supported inside the screen fixing frame by each vibration spring. The upper side of each brush strip is provided with brush bristles that contact the screen.

[0006] Furthermore, each support bar is inclined, and adjacent symmetrical support bars are arranged in a figure-eight shape. Each top vibration spring fixing bar is also inclined, and adjacent two symmetrical top vibration spring fixing bars are also arranged in a figure-eight shape. Each top vibration spring fixing bar is located above the support bar.

[0007] Furthermore, the vibration springs between the adjacent top vibration spring fixing strip and the support strip are inclined, with the upper end of the vibration spring fixed on the top vibration spring fixing strip and the lower end of the vibration spring fixed on the support strip.

[0008] Furthermore, the bottom of the bristles is embedded in the bristle fixing plate on the upper side of the bristle strip, and the bristle fixing plate is fixed to the bristle strip by screws.

[0009] Furthermore, the outer side of the baffle is fixed with reinforcing ribs, while the inner sides are fixedly connected by multiple reinforcing rods.

[0010] Furthermore, a funnel-shaped quinoa collection bin is provided below the opening of the sieve body.

[0011] Furthermore, the top cross-section of the multiple vertical bristles on each bristle strip is triangular, and the tip of the longest bristle on each bristle strip protrudes outside the surface of the screen, while the tip of the shortest bristle on each bristle strip is in the same horizontal plane as the lower surface of the screen.

[0012] By adopting the above technical solution, the sieve body of this utility model is provided with a sieve structure. The grid structure inside the sieve structure is supported inside the sieve fixing frame by each vibration spring. When the sieve body vibrates, it can drive the sieve structure to vibrate at the same time. Each vibration spring can be slightly compressed appropriately, and the grid structure vibrates as well. In this way, the two upward vibration springs form an upward support force on the grid structure, which makes it easy for the brush to contact the sieve when vibrating, regardless of whether the vibration springs on each side are contracted or extended. This ensures that the brush can fully brush the sieve when the grid structure vibrates. Similarly, the tips of the brushes of different lengths can reach the top and bottom surfaces of the sieve, so that both sides of the sieve can be brushed when vibrating, thereby effectively preventing the sieve from being blocked by quinoa particles.

[0013] This invention cleverly utilizes the vibration of the vibrating screen itself during operation to perform real-time anti-clogging and cleaning. Multiple units can be configured for multi-stage separation based on the screen mesh size. For example, a mesh size just large enough to pass through quinoa particles can be set, allowing for more efficient passage of quinoa particles and effectively preventing clogging of the screen. Larger stalks and other debris are sieved out. When the screen cannot pass through quinoa particles, fine sand and other impurities contained within the quinoa particles are sieved out. This effectively removes small impurities stuck in the screen, making it more flexible to use. Furthermore, the sieving and cleaning processes are performed simultaneously, eliminating the need to stop the machine for separate screen cleaning, thus improving the sieving efficiency and quality during quinoa processing and ultimately enhancing the quality of quinoa products.

[0017] like Figure 1-3As shown, a high-efficiency impurity removal device for quinoa processing includes a base 11 and a sieve body 12 elastically supported on the base 11. The sieve body 12 is elastically supported by a spring structure. Baffles 13 are provided on both sides of the sieve body 12. A square frame plate 14 for vibrating motors is fixed to the top of the baffles 13. Symmetrical vibrating motors 15 are fixed to the surface of the square frame plate 14. Multiple screen structures are fixed within the openings on the surface of the sieve body 12. Each screen structure includes a quadrilateral screen fixing frame 1 and square frame plates 2 covering the upper and lower openings of the screen fixing frame 1. A screen 3 is covered within the opening of the upper square frame plate 2. Multiple sets of mutually symmetrical support bars 4 are fixed to the upper two surfaces of the lower square frame plate 2. Two vibrating bars 5 are connected and fixed together by multiple parallel brush strips 6 to form a grid structure. The grid structure is installed on the screen 3. Inside the lower screen fixing frame 1, the lower side of each vibrating bar 5 is provided with the same number of top vibrating spring fixing bars 7 as the support bars 4, and every two mutually symmetrical support bars 4 are located at the center between two mutually symmetrical top vibrating spring fixing bars 7. Adjacent top vibrating spring fixing bars 7 and support bars 4 are fixedly connected by vibrating springs 8, so that the grid structure is supported inside the screen fixing frame 1 by each vibrating spring 8. The upper side of each brush bar 6 is provided with brushes 9 that contact the screen 3. The outer side of the baffle 13 is fixed with reinforcing ribs 16, and the inner sides are fixedly connected by multiple reinforcing rods 17. A funnel-shaped quinoa collection bin 18 is provided below the opening of the screen body 12.

[0018] Specifically: Each support bar 4 is inclined, and adjacent symmetrical support bars 4 are arranged in a V-shape. Similarly, each top vibration spring fixing bar 7 is inclined, and adjacent symmetrical top vibration spring fixing bars 7 are also arranged in a V-shape. Each top vibration spring fixing bar 7 is located above the support bar 4. The vibration springs 8 between adjacent top vibration spring fixing bars 7 and support bars 4 are inclined, with the upper end of the vibration spring 8 fixed to the top vibration spring fixing bar 7 and the lower end of the vibration spring 8 fixed to the support bar 4. The bottom of the bristles 9 is embedded... The bristle fixing plate 10 is located on the upper side of the bristle strip 6 and is fixed to the bristle strip 6 by screws, which facilitates the replacement of the bristles 9. The top cross-section of the multiple vertical bristles 9 on each bristle strip 6 is triangular, and the tip of the longest bristle 9 on each bristle strip 6 protrudes outside the upper surface of the screen 3, while the tip of the shortest bristle 9 on each bristle strip 6 is in the same horizontal plane as the lower surface of the screen 3. In this way, the tips of the bristles 9 of different lengths can touch the upper and lower surfaces of the screen 3, so that both sides of the screen 3 can be brushed, achieving self-cleaning on both sides and better cleaning effect.

[0019] The working principle of this utility model is the same as that of existing vibrating screen equipment, that is, the entire screen body 12 is driven to vibrate by the vibrating motor 15 to form a vibrating screening effect. The difference is that a screen structure is set inside the screen body 12. The grid structure inside the screen structure is supported inside the screen fixing frame 1 by each vibrating spring 8. When the screen body 12 vibrates, it drives the screen structure to vibrate at the same time. Each vibrating spring 8 can be slightly compressed appropriately, and the grid structure also vibrates. In this way, the two upwardly inclined vibrating springs 8 form an upward support force on the grid structure, which makes it easy for the brush bristles 9 to contact the screen 3 when vibrating, regardless of whether the vibrating springs 8 on each side are contracted or extended. This ensures that the brush bristles 9 can fully brush the screen 3 when the grid structure vibrates. Similarly, the tips of the brush bristles 9 of different lengths can reach the upper and lower surfaces of the screen 3, so that both surfaces of the screen 3 can be brushed when vibrating, thereby effectively preventing the screen from being blocked by quinoa particles.

Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
