[0023] The special component 5 for the spring energy storage quick-opening rotary ball valve includes a valve body 51, inside of which is a ball 52 for opening and closing the ball valve by rotation. The upper end of the ball 52 is connected to a quick-opening shaft 53, which is fixed to the bottom of a shaft sealing cover 54. The upper part of the shaft sealing cover 54 is fixedly connected to a ball shaft 55, thereby establishing a linkage relationship between the ball shaft 55 and the ball 52. When the ball shaft 55 rotates, it drives the ball 52 to rotate, thereby opening or closing the ball valve passage.

[0024] A rotating gear 9 is installed on the ball shaft 55 , and the rotating gear 9 is meshed and driven by a traverse linear motion mechanism. When the rotating gear 9 rotates, the ball shaft 55 is driven to rotate, and then the ball 52 is driven to rotate.

[0025] The traverse linear motion mechanism includes multiple groups of energy storage pressure spring groups 16, one end of the energy storage pressure spring group 16 is a fixed end, and the other end is fixed to the spring end plate 12. Under the action of the ball valve hydraulic control mechanism 14, the spring end plate 12 is pushed to move back and forth by the elastic force of the spring. A linear rack 10 is arranged in the middle of the spring end plate 12 and is perpendicular to it and meshes with the rotating gear 9. A rack slider 13 is arranged on the outer side of the linear rack 10.

[0026] The energy storage pressure spring group 16, the linear rack 10 and the rack slider 13 form an integrated transverse linear motion mechanism, which is controlled by the ball valve hydraulic control mechanism 14. Under the action of the elastic force, the energy storage pressure spring group 11 releases elastic potential energy, instantly pushing the spring end plate 12 to the right, so that the linear rack 10 drives the rotating gear 9 to mesh and transmit, and the rotating gear 9 then drives the ball 52 to rotate to open the ball valve. A hydraulic cylinder device 15 for pushing the linear rack 10 to move in the opposite direction is provided on one side of the free end of the linear rack 10. The hydraulic cylinder device 15 pushes the linear rack 10 in the opposite direction, so that the energy storage pressure spring group 16 is compressed, and the ball valve can be closed.

[0027] The utility model provides a special spring energy storage quick-opening rotary ball valve component which is used in special equipment for separating vascular plant tissues into straw fiber bundles. The special equipment comprises a tubular steel pressure vessel 1 which can bear pressure. A feed bin 2 is connected above the tubular steel pressure vessel 1. A feed port 21 is located above the feed bin 2. Primary materials cut into inch-long straw segments enter through the feed port 21. A feed screw 22 is provided at the bottom of the feed bin 2. The feed screw 22 spirally conveys the primary straw materials in a vertical manner. A feed bin outlet 23 is provided at the lower end of the feed screw 22. The straw materials are continuously pushed to the feed bin outlet 23 at the bottom by the feed screw 22 and then enter the tubular steel pressure vessel 1.

[0028] The tubular steel pressure vessel 1 is arranged horizontally, one end of which is the gas source end and the other end is the material delivery end. In this embodiment, the left end of the tubular steel pressure vessel 1 is the gas source end and the right end is the material delivery end. The gas at the gas source end is the pressure-adjustable normal temperature compressed air provided by the air compressor 8. Preferably, the gas source end can be connected to the compressed air storage bag 7, and the air storage bag 7 provides the gas source through the air compressor 8. The weight of the tubular steel pressure vessel 1 is supported by the equipment at the bottom.

[0029] A horizontal conveying screw 11 is provided in the feeding end to convey the straw material transported by the feeding bin 2 in a horizontal manner. The cross section of the discharge end of the horizontal conveying screw 11 gradually converges and is connected to the collecting bin 3 through the Laval three-section component 4. The Laval three-section component 4 is designed according to a structure that converges first and then expands. When the straw fiber passes through the Laval three-section component 4, the compressed air will undergo a fluid change due to the change in cross-sectional area, causing the airflow to change from subsonic to sonic and then to supersonic. When the straw fiber passes through the expansion section, the gas volume is instantly expanded, and the gas compressed in the straw vascular tube expands and does work, dissociating the straw along the natural growth direction of the straw fiber into a fiber bundle product, which is then sprayed into the collecting bin 3, so that the straw material completes the process of dissociating from inch segments into fiber bundles in the collecting bin. A collecting bin discharge screw 31 for continuous discharge is provided at the bottom of the collecting bin 3, and the dissociated fiber bundle is finally transported to the collecting bin discharge port by the collecting bin discharge screw 31.

[0030] At the feed bin discharge port 23, a conical plunger 24 is also provided which matches the gap with the lip of the feed bin discharge port 23. Generally, the straw is cut into inch-sized raw materials with a length of about 1 inch (3.2 cm) by a grass cutter and put into the feed port 21 of the feed bin. The feed screw 22 pushes the inch-sized raw materials to the feed bin discharge port 23. At the feed bin discharge port 23, the feed screw 22 continuously rotates and pushes the straw material to form a straw plug 25. The straw plug 25 forms a sealing pair with the lip of the feed bin discharge port and the conical plunger 24, sealing the feed bin discharge port 23 to achieve the purpose of auxiliary sealing, so that the tubular steel pressure vessel 1 can obtain the process pressure holding value required for dissociating the straw fiber bundles.

[0031] The bottom of the conical plunger 24 is connected to a sealing control mechanism 6, which is a sealing component for automatically and quantitatively controlling the discharge port of the feed bin. The conical plunger 24 cooperates with the sealing control mechanism 6 to better achieve the purpose of assisting the sealing of the discharge port 23 of the feed bin.

[0032] The Laval three-section component includes a convergent section 41 with a gradually narrowing cross section connected to the discharge end of the horizontal conveying screw, an expanding collection section 43 with a gradually expanding cross section connected to the inlet end of the collection bin, the expanding collection section 43 adopts a 6° to 12° taper to prevent the fluid from separating from the pipe wall, and a narrow throat section 42 arranged horizontally between the convergent section 41 and the expanding collection section 43. The cross-sectional area of ​​the narrow throat section 42 is the smallest compared to the convergent section 41 and the expanding collection section 43, and thus becomes the thinnest section in the Laval three-section component. One end of the narrow throat section 42 is connected to the convergent section 41, and the other end is connected to the expanding collection section 43. The narrow throat section 42 has a critical cross section, at which its cross-sectional area is the smallest.

[0033] Through this design of the Laval three-section component, the cross-section of the pipe through which the straw material passes is first converged and then expanded. In the tubular steel pressure vessel 1, the compressed air is first subsonic and passes through the narrow throat section 42 to achieve the purpose of supersonic airflow. The narrow throat section 42 has the ability to increase the work of airflow density. At the same time, the airflow pressure and temperature are constantly increasing. When the compressed air flow pushes the straw material through the critical cross-section of the narrow throat section 42 and enters the expansion collection section 43 of the Laval three-section component, the volume of the gas will be instantly expanded due to the sudden change of the cross-section. The gas compressed in the straw vascular tube expands and does work, tearing the straw along the direction of the straw fiber to form a fiber bundle product, and the compressed air flow is quickly sprayed into the collection bin 3 along with these straw materials.

[0034] The special component of the spring energy storage quick-opening rotary ball valve provided by the utility model is located at the narrow throat section 42. Under the control of the ball valve hydraulic control mechanism, the special component of the spring energy storage quick-opening rotary ball valve sets different gas pressure values ​​according to the different dissociation values ​​of different dissociated fiber bundle products such as wheat, corn, and rice straw, so as to realize the quick opening and closing function of the ball valve.

[0035] When the pressure in the tubular steel pressure vessel 1 reaches the set dissociation pressure value, the energy storage pressure spring group 16 releases elastic potential energy, instantly pushing the spring end plate 12 to the right, so that the linear rack 10 drives the rotating gear 9 to engage the transmission, and the rotating gear 9 then drives the ball 52 to rotate to open the ball valve. The opening of the ball valve is completed within 0.0042 seconds. At this time, the rapid airflow quickly pushes the straw material from the narrow throat section 42 into the expansion and collection section 43 instantly. In the expansion and collection section 43, microtubule plant materials such as straw expand rapidly with the airflow, and the gas compressed in the straw vascular tube expands and does work, tearing the straw along the direction of the straw fiber to become a fiber bundle product, completing the above-mentioned dissociation process.

[0036] The spring energy storage quick-opening rotary ball valve special component 5 has the function of quickly opening and closing, which satisfies the change of the spray cross-sectional area of ​​the straw and other vascular plant materials in the expansion section with the airflow, and obtains a strong airflow expansion spray force power, so as to achieve the purpose of dissociating the straw tissue into a fiber bundle product.
