Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, specifically to a wheat impurity removal device for flour processing. Background Technology

[0002] In flour processing, wheat impurity removal is a crucial step, aiming to remove various impurities from the wheat to ensure the purity and quality of the flour. Existing wheat impurity removal devices mostly employ simple sieving methods, using vibrating screens or fixed meshes to initially screen the wheat, effectively removing larger particles such as stones and sand. While this sieving method improves wheat purity to some extent, its application scope and effectiveness have significant limitations.

[0003] However, existing impurity removal devices have many shortcomings in practical applications. First, simple sieving methods are not effective at removing fine impurities such as wheat awns, dust, and light impurities. These fine impurities may mix into the flour during subsequent processing, affecting the purity and quality of the flour. Second, traditional impurity removal devices have a slow sieving speed and limited processing capacity, making it difficult to meet the needs of large-scale flour processing.

[0004] Therefore, a wheat impurity removal device for flour processing is proposed. Utility Model Content

[0024] like Figures 1 to 4 As shown, a wheat impurity removal device for flour processing includes a frame 1, a movable frame 2 slidably mounted on the surface of the frame 1, a metal mesh plate 3 fixedly installed inside the movable frame 2 for screening wheat, a spring 4 mounted on the surface of the frame 1, and two ends of the spring 4 fixedly connected to the stepped surface of the frame 1 and the end face of the movable frame 2, respectively. An air separation mechanism 5 is provided on the frame 1; Figure 1 and Figure 4 As shown, specifically, the air separation mechanism 5 includes a feeding channel 501 fixedly installed on the frame 1. An air inlet hood 502 is fixedly installed on one side wall of the feeding channel 501, and an installation frame 503 is fixedly installed on the inner wall of the air inlet hood 502. A fan 504 is fixedly installed inside the installation frame 503. An exhaust hood 505 is provided on the other side wall of the feeding channel 501, and a discharge port 506 is fixedly installed at the bottom end of the feeding channel 501.

[0025] More specifically, wheat is fed through the hopper 6 and falls through the feeding channel 501. The blower 504 generates airflow, which is then blown laterally through the air inlet hood 502 into the exhaust hood 505. Light impurities such as wheat awns and dust are blown into the exhaust hood 505 to remove them, thus achieving the air separation function and improving the purity of the wheat. The wheat is then guided through the discharge port 506 to fall onto the surface of the metal mesh plate 3.

[0026] like Figure 4 As shown, in some practical applications, the exhaust hood 505 and the air inlet hood 502 are arranged in parallel and corresponding positions, and a filter screen is fixedly installed at the air inlet end of the air inlet hood 502.

[0027] More specifically, a filter screen is fixedly installed at the air inlet of the feeding channel 501 to protect the normal operation of the fan 504 and ensure the cleanliness of the air during the air separation process, thus avoiding secondary pollution.

[0028] A hopper 6 is fixedly connected to the end of the air separation mechanism 5. A cam assembly 7 is installed on the frame 1 to drive the metal mesh plate 3 and the spring 4 to move vertically back and forth on the surface of the frame 1; Figure 2 As shown, specifically, the cam assembly 7 includes a rotating shaft 702 fixedly installed on both sides of the frame 1, and a motor 701 is fixedly installed on the surface of the frame 1. The output end of the motor 701 is fixedly connected to the end of the rotating shaft 702, and a cam body 703 is fixedly sleeved on the surface of the rotating shaft 702.

[0029] More specifically, the rotating shaft 702 is driven to rotate by the electric motor 701, and the eccentric design of the cam body 703 causes the movable frame 2 to move vertically back and forth on the surface of the frame 1, which drives the metal mesh plate 3 to vibrate, thereby realizing the vibration screening of wheat and improving screening efficiency and effect.

[0030] In some practical applications, the inner wall of the silo 6 is fixedly equipped with a guide plate 61 to filter the large straw of wheat before it falls into the air separation mechanism 5.

[0031] More specifically, before the wheat falls into the feeding channel 501, the guide plate 61 performs preliminary filtration of larger impurities such as large straw in the wheat to prevent these impurities from entering the feeding channel 501 and affecting the air separation effect.

[0032] In some practical applications, the surface of the frame 1 and the inner wall of the movable frame 2 are coated with lubricating oil to facilitate the stable sliding of the movable frame 2 on the surface of the frame 1.

[0033] More specifically, the surfaces of the frame 1 and the movable frame 2 are coated with lubricating oil to reduce the friction when the movable frame 2 slides on the surface of the frame 1, ensuring that the movable frame 2 can slide stably and smoothly, and extending the service life of the equipment.

[0034] In summary: A metal mesh plate 3 is fixedly installed inside the movable frame 2 for screening wheat. The two ends of the spring 4 are fixedly connected to the stepped surface of the frame 1 and the end face of the movable frame 2, respectively, to play a resetting role. A hopper 6 is fixedly connected to the end of the air separation mechanism 5 for air separation of wheat to remove light impurities. The cam assembly 7 is used to drive the metal mesh plate 3 and the spring 4 to move vertically back and forth on the surface of the frame 1 to realize the vibration screening of wheat and improve screening efficiency.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
