Description

Technical Field

[0001] The invention relates to the technical field of feed processing, in particular to a straw feed blasting reactor. Background Art

[0002] Steam explosion, a recently emerging fiber processing technology, works by penetrating steam molecules into plant tissue and then releasing them instantly. This process converts the steam's internal energy into mechanical energy, which acts on the intercellular layers of the plant tissue, disrupting the fiber structure and releasing nutrients. This technology boasts a short processing time, low cost, no pollution, and high effectiveness. Research has shown that steam explosion significantly increases corn stover utilization, significantly enhances rumen fermentation levels, significantly eliminates microorganisms and mycotoxins, and significantly improves production performance and product quality.

[0003] The blasting reactor includes a reactor body. After straw feed is added to the reactor body, high-pressure steam is introduced into the reactor body. After reaching a preset pressure, the pressure is maintained for a period of time. Then, the discharge port is opened to instantly release the straw feed into the blasting chamber to complete the blasting. In the use of existing blasting reactors, it has been found that the straw feed at the discharge port can be instantly released into the blasting chamber. However, as the pressure in the reactor body decreases, the release pressure of the straw feed inside the reactor body away from the discharge port becomes increasingly smaller, making it impossible to achieve instant blasting of the straw feed, which affects the blasting rate of the straw feed.

[0031] See also Figures 1 to 6The embodiment of the present application provides a straw feed blasting reactor, comprising: a reactor body 1, having a chamber and a steam pipe 11 connected to the chamber, the steam pipe 11 being connected to an external high-pressure steam source, a partition 12 being arranged in the chamber, the partition 12 dividing the chamber into a first chamber 13 and a second chamber 14, the partition 12 being provided with a first communicating hole 121 for communicating the first chamber 13 and the second chamber 14, the top and bottom of the reactor body 1 being respectively provided with a feed port 15 connected to the first chamber 13 and a discharge port 16 connected to the second chamber 14; and a sealing mechanism 2, comprising a sealing plate 21 rotatably arranged on the upper surface of the partition 12 and a driving assembly 22 for driving the sealing plate 21 to rotate, the sealing plate 21 having a second communicating hole 211 communicating with the first communicating hole 121 and a sealing portion 212 for covering the first communicating hole 121.

[0032] In the present application, straw feed is added into the chamber through the feed port 15, and the sealing plate 21 is driven to rotate by the driving component 22 so that the second connecting hole 211 of the sealing plate 21 is aligned with the first connecting hole 121 of the partition 12, and the first chamber 13 and the second chamber 14 remain connected. High-pressure steam is introduced through the steam pipe 11 to maintain high temperature and pressure on the straw feed in the chamber. When the straw feed needs to be discharged and blasted, the sealing plate 21 is rotated so that the sealing part 212 of the sealing plate 21 closes the first connecting hole 121, and the first chamber 13 is isolated from the second chamber 14. Then, the discharge port 16 is opened to complete the blasting and discharge of the straw feed in the second chamber 14. Then, the discharge port 16 is closed, and the straw feed is introduced into the second chamber 14 and blasted again until the blasting and discharge of all the feed in the kettle body 1 is completed. This can ensure that the straw feed in the kettle body 1 is fully blasted and the blasting rate of the straw feed is improved.

[0033] Specifically, the space of the second chamber 14 in the present application can ensure that the straw feed in the second chamber 14 is exploded and discharged at one time. The space of the first chamber 13 is larger than the space of the second chamber 14. The straw feed in the first chamber 13 is introduced into the second chamber 14 in batches to complete the blasting and discharge. The space of the first chamber 13 and the space of the second chamber 14 are also equal. The straw feed in the first chamber 13 can be added to the second chamber 14 at one time to complete the blasting and discharge.

[0034] Specifically, if the air pressure in the cavity does not reach the blasting pressure, the interior of the cavity may be inflated and pressurized during subsequent blasting and discharge.

[0035] In some embodiments, the top of the partition 12 adopts a concave structure, and the bottom of the sealing plate 21 adopts a convex structure that cooperates with the concave structure. A sealing member 122 is provided on the upper surface of the partition 12 around the first connecting hole 121, and the sealing member 122 abuts against the bottom of the sealing plate 21.

[0036] In the present application, the partition 12 adopts a concave structure and the sealing plate 21 adopts a convex structure. When the straw feed in the second chamber 14 is exploded, there is a large pressure difference between the first chamber 13 and the second chamber 14, so that the sealing plate 21 presses the seal 122 to ensure the sealing performance. Moreover, when the second connecting hole 211 is connected to the first connecting hole 121, the concave structure of the partition 12 facilitates the straw feed in the first chamber 13 to fall into the second chamber 14.

[0037] In some embodiments, the driving assembly 22 includes: a driving shaft 221, a driving motor 222 and a driving shaft 223, wherein:

[0038] The driving shaft 221 is used to drive the sealing plate 21 to rotate. The driving shaft 221 passes through the partition 12. The driving shaft 221 is provided with a connecting air channel 2211 along its own axial direction. The connecting air channel 2211 has a first opening 2212 connected to the first chamber 13 and a second opening 2213 connected to the second chamber 14.

[0039] The driving motor 222 is arranged on the kettle body 1 .

[0040] One end of the drive shaft 223 is connected to the power output end of the drive motor 222 , and the other end is connected to the driving shaft 221 . The drive shaft 223 is movable along its own axis to open and close the first opening 2212 of the communicating airway 2211 .

[0041] In the present application, the driving motor 222 drives the driving shaft 223 to rotate, and the driving shaft 223 drives the driving shaft 221 and the sealing plate 21 to rotate, which is used to control the connection between the first chamber 13 and the second chamber 14. The driving shaft 223 can move axially to control the opening and closing of the first opening 2212. When the straw feed in the second chamber 14 is blasted and discharged, the first opening 2212 is in a closed state. The first chamber 13 and the second chamber 14 ensure sealing under the action of the pressure difference. After the discharge port 16 is closed, the driving shaft 223 opens the first opening 2212, so that the first chamber 13 is connected to the second chamber 14. There is no pressure difference between the upper and lower parts of the sealing plate 21, which facilitates the rotation of the sealing plate 21.

[0042] In some embodiments, a fixed plate 17 is provided in the first chamber 13 of the kettle body 1, and the top of the driving shaft 221 passes through the fixed plate 17. The top of the driving shaft 221 is provided with a transmission groove 2214 connected to the connecting air channel 2211, and the bottom of the driving shaft 223 is inserted into the transmission groove 2214, and a sealing assembly is provided at the bottom of the driving shaft 223, which is inserted into the connecting air channel 2211 for opening and closing the first opening 2212.

[0043] In this application, the top and bottom of the driving shaft 221 pass through the fixed plate 17 and the partition 12 respectively, and the driving shaft 221 is connected to the fixed plate 17 and the partition 12 through bearings to ensure the stability of the driving shaft 221. The transmission groove 2214 adopts an internal hexagonal hole, and the bottom of the driving shaft 223 is a hexagonal head. After being inserted into the transmission groove 2214, it drives the driving shaft 221 to rotate, and the opening and closing of the first opening 2212 is controlled by the sealing assembly at the bottom of the driving shaft 223.

[0044] Furthermore, the connecting air channel 2211 includes a ventilation section at the bottom and a sealing section connected to the top of the ventilation section, the inner diameter of the sealing section is larger than the inner diameter of the ventilation section, the first opening 2212 is connected to the sealing section, and the sealing assembly includes: a mounting rod 2231, which is connected to the bottom of the driving shaft 221, the mounting rod 2231 is inserted into the sealing section of the connecting air channel 2211 and is coaxially arranged with the sealing section; and an elastic sealing ring 2232, which is sleeved on the outer peripheral side of the mounting rod 2231, the bottom of the elastic sealing ring 2232 abuts against the inner bottom wall of the sealing section, and the outer peripheral side of the elastic sealing ring 2232 abuts against the side wall of the sealing section to seal the first opening 2212.

[0045] In the present application, the outer diameter of the elastic sealing ring 2232 in its natural state is equal to the inner diameter of the sealing section. When the elastic sealing ring 2232 moves upward for a distance along with the mounting rod 2231, the first opening 2212 is connected to the sealing section, and then the first opening 2212 is connected to the communicating airway 2211. When the first opening 2212 needs to be closed, the mounting rod 2231 drives the elastic sealing ring 2232 to move downward until the bottom of the elastic sealing ring 2232 abuts against the inner bottom wall of the sealing section, and continues to move downward to squeeze and deform the elastic sealing ring 2232. The outer surface of the elastic sealing ring 2232 fully abuts against the inner side wall of the sealing section, thereby closing the first opening 2212. The first opening 2212 can be quickly switched between open and closed, and the sealing effect can be guaranteed.

[0046] In some embodiments, the first opening 2212 is disposed along the radial direction of the driving shaft 221 , and the thickness of the elastic sealing ring 2232 is greater than the diameter of the first opening 2212 .

[0047] In the present application, the thickness of the elastic sealing ring 2232 is greater than the diameter of the first opening 2212 , so that the elastic sealing ring 2232 can fully seal the first opening 2212 .

[0048] In some embodiments, the driving assembly 22 further includes a lifting cylinder 224 mounted on the kettle body 1 and a lifting frame 225 disposed at a movable end at the bottom of the lifting cylinder 224 , and the driving motor 222 is disposed on the lifting frame 225 .

[0049] In the present application, the lifting frame 225 and the driving motor 222 are driven to move up and down by the lifting cylinder 224, so that the driving shaft 223 can move up and down, ensuring that the driving shaft 221 can be driven to rotate while controlling the opening and closing of the first opening 2212.

[0050] In some embodiments, a spiral scraper assembly 3 is further included, which is arranged on the outer peripheral side of the driving shaft 221 , and the outer peripheral side of the spiral scraper assembly 3 abuts against the inner wall of the chamber.

[0051] In the present application, by driving the spiral scraper assembly 3 to rotate through the driving shaft 221, the straw feed attached to the inner surface of the chamber can be cleaned and vertically transported, making it convenient to push the straw feed in the first chamber 13 into the second chamber 14.

[0052] Furthermore, the spiral scraper assembly 3 includes a spiral scraper 31 and a connecting rod 32. The spiral scraper 31 is connected to the driving shaft 221 via the connecting rod 32. The connecting rod 32 adopts an inverted V-shaped structure.

[0053] In the present application, the spiral scraper drives the straw feed on the inner surface of the chamber downward when rotating. The connecting rod 32 adopts an inverted V-shaped structure for the downward transportation of the straw feed, which will not affect the downward transportation of the straw feed. Moreover, when maintaining high temperature and pressure, the spiral scraper 31 can be driven by the driving shaft 221 to rotate in the opposite direction to transport the straw feed upward. The connecting rod 32 stirs the straw feed, so that the straw feed maintains a certain fluffiness, which facilitates the immersion of high-temperature water molecules into the straw feed.

[0054] In some embodiments, a driving hole is provided in the middle of the sealing plate 21, and the driving shaft 221 passes through the driving hole. A rubber ring 2215 is provided on the outer peripheral side of the driving shaft 221, and the rubber ring 2215 is in friction contact with the inner surface of the driving hole. A stopper 123 for limiting the sealing plate 21 is provided on the partition 12 so that the sealing portion 212 of the sealing plate 21 or the second connecting hole 211 is aligned with the first connecting hole 121.

[0055] In the present application, the driving shaft 221 drives the sealing plate 21 to rotate through the friction between the rubber ring 2215 and the driving hole, and the sealing plate 21 is limited by the block 123, so that the sealing plate 21 can stay in a state where the second connecting hole 211 is aligned with the first connecting hole 121 or the sealing part 212 is aligned with the first connecting hole 121, and then the driving shaft 221 rotates without driving the sealing plate 21 to rotate, thereby transporting the straw feed.

[0056] The straw feed blasting reactor adds straw feed into the chamber through the feed inlet 15, and drives the sealing plate 21 to rotate through the driving component 22 so that the second communicating hole 211 of the sealing plate 21 is aligned with the first communicating hole 121 of the partition plate 12, and the first chamber 13 and the second chamber 14 remain connected. High-pressure steam is introduced through the steam pipe 11 to maintain the high temperature and pressure of the straw feed in the chamber. When the straw feed needs to be discharged and blasted, the sealing plate 21 is rotated so that the sealing part 212 of the sealing plate 21 closes the first communicating hole 121, and the first chamber 13 is isolated from the second chamber 14. Then, the discharge port 16 is opened to complete the blasting and discharge of the straw feed in the second chamber 14. Then, the discharge port 16 is closed, and the straw feed is introduced into the second chamber 14 and blasted again until the blasting and discharge of all the feed in the reactor body 1 is completed. This can ensure that the straw feed in the reactor body 1 is fully blasted and the blasting rate of the straw feed is improved.
