Description

Technical Field

[0001] This utility model relates to the technical field of grain processing equipment, specifically to a soybean screening, miscellaneous straw crushing and inactivation system. Background Technology

[0002] During the processing of imported genetically modified soybeans, the by-products generated during screening (including light impurities such as pods and straw, and heavy impurities such as stones and clods of soil) must be effectively inactivated to prevent the spread of genetically modified components or potentially bioactive substances and to meet quarantine and environmental protection requirements.

[0003] However, existing inactivation systems are usually designed only for light impurities and mostly use single-chamber or static inactivation methods, which do not provide ideal inactivation results. In addition, to ensure the consistency of inactivation results, light impurities need to be accurately and stably metered, which often uses metering devices such as rotary valves. However, existing rotary valves are prone to adhesion, bridging or blockage when handling high-moisture and high-fiber materials, causing fluctuations in metering and a decrease in metering accuracy, which in turn affects the overall consistency of inactivation.

[0004] To address these issues, a soybean screening and crushing / inactivation system for miscellaneous straw is provided. Utility Model Content

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1 To address the issue that existing inactivation systems often employ single-chamber or static methods for light impurity inactivation, making dynamic continuous inactivation difficult and resulting in less than ideal inactivation effects, please refer to... Figures 1-2 This utility model provides a soybean screening and straw crushing and inactivation system, including a waste material conveying trough 1 for conveying waste materials after screening and cleaning of genetically modified soybeans, and a light waste (pods, straw, etc.) inactivation component and a heavy waste (stones, soil, etc.) inactivation component connected to the end of the waste material conveying trough 1; the light waste inactivation component includes a first light waste suction pipe 2, a crusher 4, a second light waste suction pipe 5, a hopper 6, an inactivation unit 7 and a cooling dryer 8 connected in sequence along the light waste treatment path, the first light waste suction pipe 2 is used to suck the light waste in the waste material conveying trough 1 into the crusher 4; the heavy waste inactivation component includes a heavy waste conveying pipe 3 and a screw conveyor 9, the heavy waste conveying pipe 3 is used to guide the heavy waste in the waste material conveying trough 1 into the screw conveyor 9.

[0020] It should be noted that the top of the hopper 6 is equipped with a suction drive component. The suction drive component generates negative pressure to suck the light impurities crushed by the crusher 4 into the hopper 6 for storage.

[0021] The inactivation unit 7 includes a first inactivation cylinder 701 and a second inactivation cylinder 702 arranged in layers and connected in series. The inlet end of the first inactivation cylinder 701 is connected to the outlet of the hopper 6, the outlet end of the first inactivation cylinder 701 is connected to the inlet end of the second inactivation cylinder 702, and the outlet end of the second inactivation cylinder 702 is connected to the inlet of the cooling dryer 8. A steam input unit 703 is provided on the downstream side of the inlet end of both the first inactivation cylinder 701 and the second inactivation cylinder 702 to introduce inactivation steam into the cylinder. Both the first inactivation cylinder 701 and the second inactivation cylinder 702 are provided with a spiral stirring unit 704 for material mixing and axial conveying, so that the material and steam can be in full contact. The dual-stage inactivation cylinder extends the residence time of light impurities in a high-temperature and high-humidity environment, significantly improving the inactivation rate of genetically modified components or potential bioactive substances. Furthermore, the stacked arrangement of the first inactivation cylinder 701 and the second inactivation cylinder 702 not only makes the path of light impurities more convoluted but also saves floor space.

[0022] Two sets of spaced-apart steam input units 703 are also provided on the downstream side of the feed end of the screw conveyor 9. The two sets of steam input units 703 introduce steam into the screw conveyor 9 to perform two consecutive steam inactivation processes on heavy and impurities.

[0023] In use, light impurities are drawn into the crusher 4 through the first light impurity suction pipe 2 for crushing. The crushed material enters the hopper 6 through the second light impurity suction pipe 5. The material in the hopper 6 is sent to the inactivation unit 7. The material is inactivated in the first inactivation cylinder 701 and the second inactivation cylinder 702 by high-temperature steam provided by the steam input unit 703. The spiral stirring unit 704 achieves uniform mixing and conveying. Finally, the inactivated material enters the cooling dryer 8 for cooling and drying. Heavy impurities are introduced into the spiral conveyor 9 through the heavy impurity conveying pipe 3 and undergo two inactivation treatments through the steam input unit 703 during the conveying process.

[0024] Example 2 Based on Example 1, to address the problem that existing rotary discharge valves easily cause bridging and agglomeration during the discharge of pulverized genetically modified soybean by-products containing pods, straw fragments, fiber, dust, etc., leading to inaccurate quantification and affecting subsequent inactivation effects, such as... Figures 3-6 As shown, a rotary valve assembly 10 for quantitative feeding is also provided between the hopper 6 and the inactivation unit 7; the rotary valve assembly 10 includes a valve body 1001, two sets of bearing seats 1003 symmetrically fixed on both sides of the valve body 1001, a rotating shaft 1002 rotatably disposed in the two sets of bearing seats 1003, a motor 1004 for driving the rotating shaft 1002 to rotate, and a plurality of blades 1005 uniformly fixed on the outer periphery of the rotating shaft 1002 along the circumference; adjacent blades 1005 and the outer periphery of the rotating shaft 1002 together form a metering cavity for containing materials.

[0025] The rotary valve assembly 10 also includes an airflow unit 1006 for assisting in feeding to avoid clogging and sticking; the airflow unit 1006 includes an air inlet ring 1006a fixedly disposed at the end of the valve body 1001 and an air inlet pipe 1006b communicating with the air inlet ring 1006a, the air inlet ring 1006a being rotatably connected to the rotating shaft 1002; the rotating shaft 1002 has an axially extending airflow channel inside, the rotating shaft 1002 has an air inlet hole 1002b communicating with the airflow channel on the peripheral surface of the rotating shaft 1002 corresponding to the air inlet ring 1006a, and the rotating shaft 1002 has a first air outlet hole 1002a communicating with the airflow channel on the peripheral surface of each metering chamber. The air source is introduced into the air intake ring 1006a through the air intake pipe 1006b, and enters the air flow channel inside the rotating shaft 1002 through the air intake hole 1002b on the side of the rotating shaft 1002. It is then directionally ejected from the first air outlet 1002a to assist in pushing the material in the metering chamber and avoid residual blockage.

[0026] To prevent material from entering the first vent 1002a and causing blockage during feeding, such as Figure 7 As shown, the bottom surface of each metering chamber is also provided with an axially movable sealing plate 1007. The sealing plate 1007 is used to selectively open or close the first vent 1002a. Both ends of the rotating shaft 1002 are fixedly fitted with positioning rings 1002c. The sealing plate 1007 slides between the two positioning rings 1002c. The positioning rings 1002c guide the axial movement of the sealing plate 1007. A second vent 1007a is opened on the sealing plate 1007 at the position corresponding to the first vent 1002a.

[0027] One end of the sealing plate 1007 is provided with a drive unit 1008 for driving its axial movement; the drive unit 1008 includes a fixed frame 1008a fixedly mounted on the end face of the positioning ring 1002c, a movable rod 1008b fixedly mounted on the end face of the sealing plate 1007, and a cam ring 1008e fixedly mounted on the valve body 1001; the movable rod 1008b movably passes through the fixed frame 1008a, and a spring 1008c is sleeved on the movable rod 1008b; the end of the movable rod 1008b is provided with a stop block 1008d, and the stop block 1008d rolls with the cam ring 1008e.

[0028] When the metering chamber rotates with the rotating shaft 1002 to the lower discharge position, the abutment 1008d engages with the protrusion of the cam ring 1008e, driving the sealing plate 1007 to move axially so that the second vent 1007a aligns with the first vent 1002a, and the first vent 1002a opens; when the metering chamber rotates to the upper feed position, the abutment 1008d engages with the recess of the cam ring 1008e, the spring 1008c resets and drives the sealing plate 1007 to move in the opposite direction, the second vent 1007a is misaligned with the first vent 1002a, and the first vent 1002a closes.

[0029] To ensure accurate metering by vibrating the material inside the metering chamber during feeding, such as... Figure 7 As shown, the other end of the sealing plate 1007 is provided with a vibration unit 1009 for vibrating the material; the vibration unit 1009 includes a vibrator 1009a fixedly mounted on the valve body 1001 and a vibration transmission block 1009b fixedly mounted on the output end of the vibrator 1009a; the vibration transmission block 1009b is adapted to the end face of the other end of the sealing plate 1007 to ensure effective transmission of vibration. When the metering chamber rotates to the upper feed position, the arc-shaped surface of the sealing plate 1007 abuts against the vibration transmission block 1009b, and the vibration generated by the vibrator 1009a is transmitted to the sealing plate 1007 through the vibration transmission block 1009b. The vibration promotes the material to be fully filled and compacted, improves the metering accuracy, and prevents bridging.

[0030] In practical use, light impurities in the hopper 6 enter the rotary valve assembly 10. The motor 1004 drives the rotating shaft 1002 to rotate. When the metering chamber rotates with the rotating shaft 1002 to the upper feeding position, the drive unit 1008 drives the sealing plate 1007 to move axially to close the first air outlet 1002a. At the same time, the vibration unit 1009 abuts against the sealing plate 1007, and the sealing plate 1007 vibrates the material in the metering chamber to prevent agglomeration and ensure that the material is densely filled. When the metering chamber rotates to the lower discharge position, the drive unit 1008 drives the sealing plate 1007 to move axially to open the first air outlet 1002a. The compressed air of the airflow unit 1006 pushes the material to achieve residue-free discharge, which is fully adapted to the scenario of high moisture, high fiber, and easy stickiness of genetically modified soybean by-products.

[0031] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
