Description

Technical Field

[0001] The present invention belongs to the technical field of distiller's grains fermentation, and specifically relates to a device and a preparation method for efficiently fermenting carbon sources using distiller's grains. Background Art

[0002] Distiller's grains are the main by-products of the brewing industry, rich in organic components such as cellulose, starch, and protein. They can be used as low-cost and renewable carbon sources and can be converted into high-value-added carbon sources through fermentation technology, such as volatile fatty acids (VFA), ethanol, and methane, which are widely used in fields such as sewage treatment, bioenergy production, and microbial culture.

[0003] In the process of preparing distiller's grains fermented carbon sources, the key equipment includes a pretreatment system (crushing, hydrolysis), a fermentation reactor (anaerobic / aerobic), a product separation device (solid-liquid separation, distillation), and an intelligent control system.

[0004] However, during the pretreatment of distiller's grains, the distiller's grains contain a large amount of incompletely decomposed grain husks and plant cell wall structures, which makes it difficult for microorganisms and enzymes to effectively contact the internal organic matter, easily causing an imbalance in the initial carbon-nitrogen ratio and affecting the growth and metabolism of microorganisms. In addition, when the lignocellulose structure in the distiller's grains is not destroyed, cellulase is difficult to effectively act on the crystalline region, resulting in a 30% - 50% decrease in saccharification efficiency, an extended fermentation cycle, and an increased production cost.

[0005] Therefore, the present invention provides a device and a preparation method for efficiently fermenting carbon sources using distiller's grains. Summary of the Invention

[0024] A method for using a device for efficiently fermenting carbon source from distiller's grains, comprising the following steps:

[0025] S1: First, open the feed inlet, send the distiller's grains into the interior of the fermentation barrel. The distiller's grains enter the interior of the crushing box through the gaps between multiple baffle plates. Then, through the reciprocating sliding of the piston inside the air cylinder, gas is sent into the elastic block to block the gaps between the multiple baffle plates.

[0026] S2: Second, drive the driving wheel and the driven wheel to rotate through the driving motor, and control the crushing blades to crush the distiller's grains.

[0027] S3: Finally, control the scraping ring to slide down along the interior of the crushing box to scrape off the attached distiller's grains.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. In the device and preparation method for efficiently fermenting carbon source from distiller's grains of the present invention, the driving motor drives the driving wheel to rotate. Under the action of the belt, the driven wheel is driven to rotate. At this time, the rotating shaft drives the air ring to rotate, and the first bevel gear and the second bevel gear are engaged in cooperation with the rotating rod. The second reciprocating lead screw drives the transmission rod and the piston to reciprocate inside the air cylinder. Through the cooperation of the first air pipe and the second air pipe, gas can be transported into the interior of the air ring, and then into the interior of the elastic block to fill the gaps between the multiple baffle plates. At the same time, the rotating shaft also drives the crushing blades to crush the distiller's grains, which can effectively destroy the lignocellulose structure in the distiller's grains and act on the crystallization area, thereby reducing the fermentation period and further reducing the production cost.

[0030] 2. In the device and preparation method for efficiently fermenting carbon source from distiller's grains of the present invention, by controlling the driving motor to reverse, the positioning ring drives the toothed ring to reverse and drives the control gear to rotate. Under the cooperation of the ratchet lever and the ratchet wheel, the first reciprocating lead screw can be driven to rotate. At this time, the scraping ring reciprocates up and down along the interior of the crushing box to scrape off the distiller's grains attached to the inner wall of the crushing box. At the same time, the top pressure rod arranged at the bottom of the scraping ring can press the top of the C-shaped buckle to release its limit on the blocking cone, automatically completing the unloading of the crushing box, which helps the distiller's grains to ferment inside the fermentation barrel.

[0044] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0045] like Figures 1 to 10 As shown, an apparatus for preparing a carbon source by using wine lees for efficient fermentation according to an embodiment of the present invention comprises a fermentation barrel 1, and a feed port 2 is provided on the fermentation barrel 1;

[0046] The fermentation barrel 1 is provided with a crushing box 3 with a top opening. A rotating shaft 8 is rotatably installed inside the crushing box 3. A crushing blade 6 is fixedly installed on the outer wall of the rotating shaft 8. A blocking cone 7 is slidably installed at the bottom end of the crushing box 3.

[0047] When the rotating shaft 8 rotates, it can drive the crushing blade 6 to rotate. At this time, the lees entering the crushing box 3 can be crushed again, which can destroy the lignocellulose structure in the lees and effectively act on the crystallization area, thereby reducing the fermentation cycle and further reducing production costs.

[0048] An air ring 25 is rotatably installed inside the crushing box 3, and a plurality of shielding pieces 4 are fixedly installed on the outer wall of the air ring 25. A positioning ring 5 is fixedly installed on the outer wall of the plurality of shielding pieces 4. The positioning ring 5 is rotatably connected to the crushing box 3. Gaps are left between the plurality of shielding pieces 4 for the lees to fall. An elastic block 24 with a cavity is slidably installed between the two shielding pieces 4. The inner cavities of the plurality of elastic blocks 24 are all in communication with the inner cavity of the air ring 25.

[0049] The fermentation barrel 1 is provided with a gas supply assembly for delivering gas to the interior of the elastic block 24;

[0050] The gas is transported to the inside of the air ring 25 through the provided air supply component, and then enters the inside of the plurality of elastic blocks 24. The elastic blocks 24 are deformed by air pressure and move through the gaps between the plurality of shielding sheets 4. The gaps can be blocked by the deformation of the elastic blocks 24. At this time, the plurality of elastic blocks 24 and the shielding sheets 4 can block the top opening of the crushing box 3, so that when the crushing blade 6 crushes the distillers grains, they will not fly out.

[0051] A locking component is arranged inside the crushing box 3 for locking the blocking frustum 7 inside the crushing box 3.

[0052] When the blocking frustum 7 is located at the bottom of the crushing box 3, the provided locking component can fix the current position of the blocking frustum 7, effectively blocking the distillers grains inside the crushing box 3. When the locking component releases the fixation of the blocking frustum 7, the blocking frustum 7 will slide out of the inside of the crushing box 3. At this time, the crushed distillers grains inside the crushing box 3 can fall into the fermentation barrel 1 for fermentation.

[0053] As a preferred embodiment of the present invention, the air supply component includes an air cylinder 16, a piston 17, a first air pipe 18 and a second air pipe 19. The air cylinder 16 is fixedly installed inside the fermentation barrel 1, the piston 17 is slidably installed inside the air cylinder 16, both the first air pipe 18 and the second air pipe 19 are fixedly installed on the air cylinder 16. The other end of the first air pipe 18 extends outside the fermentation barrel 1, and the other end of the second air pipe 19 extends into the inside of the air ring 25. One-way valves are arranged on both the first air pipe 18 and the second air pipe 19.

[0054] The one-way valve arranged on the first air pipe 18 only allows the outside gas to enter the inside of the air cylinder 16.

[0055] The one-way valve arranged on the second air pipe 19 only allows the gas inside the air cylinder 16 to enter the inside of the second air pipe 19.

[0056] Therefore, when the piston 17 slides leftward inside the air cylinder 16, the first air pipe 18 will suck the outside gas into the inside of the air cylinder 16. When the piston 17 slides rightward inside the air cylinder 16, the gas inside the air cylinder 16 can be sent into the inside of the air ring 25 through the second air pipe 19, and finally the elastic blocks 24 are deformed.

[0057] As a preferred embodiment of the present invention, one end of the piston 17 is fixedly installed with a transmission rod 21. A second reciprocating lead screw 20 is connected inside the transmission rod 21 by threads. The end of the second reciprocating lead screw 20 far from the piston 17 is fixedly installed with a first bevel gear 22. A rotating rod 27 is fixedly installed inside the air ring 25, and a second bevel gear 23 meshing with the first bevel gear 22 is fixedly installed at the top of the rotating rod 27.

[0058] When the air ring 25 rotates, it can drive the rotating rod 27 to rotate synchronously. Therefore, the first bevel gear 22 can be driven to rotate by the second bevel gear 23, so that the second reciprocating lead screw 20 rotates, and the transmission rod 21 will drive the piston 17 to slide reciprocally inside the air cylinder 16.

[0059] As a preferred embodiment of the present invention, a rotating ring 26 is rotatably installed at the top end of the air ring 25. One end of the second air pipe 19 penetrates through the rotating ring 26 and extends into the air ring 25. A third air pipe 29 is provided on the rotating ring 26. The other end of the third air pipe 29 extends outside the fermentation barrel 1, and a pressure relief valve is provided on the third air pipe 29.

[0060] When the rotating ring 26 drives the air ring 25 to rotate, it will not affect the connection between the second air pipe 19 and the air ring 25.

[0061] The setting of the third air pipe 29 can discharge the excess gas after the gas inside the elastic block 24 is saturated.

[0062] As a preferred embodiment of the present invention, the locking assembly includes an annular card slot 30 and a C-shaped buckle 31. The annular card slot 30 is opened on the outer wall of the blocking frustum 7. The C-shaped buckle 31 is elastically installed on the inner wall of the crushing box 3, and the top and bottom ends of the C-shaped buckle 31 are both inclined.

[0063] When the blocking frustum 7 is located at the bottom end of the crushing box 3, the bottom end of the C-shaped buckle 31 will snap into the annular card slot 30 to limit the blocking frustum 7.

[0064] Since the top and bottom ends of the C-shaped buckle 31 are both inclined, the C-shaped buckle 31 can be pushed into the crushing box 3 and separated from the blocking frustum 7 by pressing from the top and bottom ends of the C-shaped buckle 31.

[0065] As a preferred embodiment of the present invention, a first reciprocating lead screw 10 is rotatably installed inside the crushing box 3. A scraping ring 11 is slidably installed on the first reciprocating lead screw 10. The outer wall of the scraping ring 11 fits against the inner wall of the crushing box 3. A pressing rod 15 for pressing the C-shaped buckle 31 is fixedly installed at the bottom end of the scraping ring 11;

[0066] When the first reciprocating lead screw 10 rotates, it can drive the scraping ring 11 to slide on the inner wall of the crushing box 3, scrape off the distillers' grains adhering to the inner wall of the crushing box 3, improve the discharge rate, and the pressing rod 15 provided at the bottom of the scraping ring 11 can press the top of the C-shaped buckle 31 to release the limit of the blocking frustum 7, and discharge the crushed distillers' grains inside the crushing box 3.

[0067] By controlling the forward and reverse rotation of the first reciprocating lead screw 10, the up and down sliding of the scraping ring 11 can be controlled.

[0068] The positioning rod 9 is elastically installed inside the rotating shaft 8, and the other end of the positioning rod 9 is fixedly connected to the blocking frustum 7;

[0069] The elastically arranged positioning rod 9 can make the blocking frustum 7 always tend to be located inside the crushing box 3. Therefore, when the C-shaped buckle 31 releases the limit on the blocking frustum 7, at this time, the weight of the distiller's grains can drive the blocking frustum 7 to slide out from the inside of the crushing box 3 until the distiller's grains are completely discharged, and then the blocking frustum 7 is pulled back into the inside of the crushing box 3 by the elastic force, and the bottom end of the C-shaped buckle 31 is pressed, which is convenient for the C-shaped buckle 31 to re-limit the blocking frustum 7.

[0070] The bottom end of the blocking frustum 7 is connected to the bottom end of the crushing box 3 by a safety rope 32.

[0071] The safety rope 32 provided can limit the sliding distance of the blocking frustum 7.

[0072] As a preferred embodiment of the present invention, an installation table 40 is fixedly installed inside the crushing box 3 and coincides with the axis of the rotating shaft 8. A first transmission block 33 and a first transmission gear 34 are rotatably installed inside the installation table 40. A first tooth block meshing with the first transmission gear 34 is fixedly installed on the first transmission block 33, and the first transmission block 33 is fixedly connected to the rotating shaft 8;

[0073] When the rotating shaft 8 rotates, it can drive the first transmission block 33 to rotate. Through the setting of the first tooth block, when the first transmission block 33 rotates one circle, the first transmission gear 34 can be driven to rotate a certain distance.

[0074] A second transmission block 35 is fixedly installed at the top end of the first transmission gear 34. A second transmission gear 28 is fixedly installed on the outer wall of the rotating rod 27. A second tooth block meshing with the second transmission gear 28 is fixedly installed on the second transmission block 35.

[0075] When the first transmission gear 34 rotates, it can drive the second transmission block 35 to rotate. Under the setting of the second tooth block, when the second transmission block 35 rotates one circle, the second transmission gear 28 can be driven to rotate a certain distance.

[0076] Through the setting of the differential speed, the rotation speed of the crushing blade 6 can be effectively slowed down, and the kinetic energy is transmitted to the rotating rod 27, and the first bevel gear 22 and the second bevel gear 23 are cooperated to control the piston 17 to reciprocate inside the air cylinder 16, and is conveyed to the elastic block 24 through the gas to block the top opening of the crushing box 3.

[0077] As a preferred embodiment of the present invention, a toothed ring 36 is fixedly installed at the bottom end of the positioning ring 5, and a control gear 37 meshing with the toothed ring 36 is arranged at the top end of the first reciprocating lead screw 10;

[0078] Inside the control gear 37, a ratchet wheel 38 is rotatably installed. The ratchet wheel 38 is fixedly connected to the first reciprocating lead screw 10. Inside the control gear 37, a ratchet lever 39 is elastically installed for blocking the rotation of the ratchet wheel 38.

[0079] When the positioning ring 5 rotates, it can drive the toothed ring 36 to rotate. The ratchet lever 39 can block the clockwise rotation of the ratchet wheel 38. Therefore, when the toothed ring 36 rotates counterclockwise, at this time, the control gear 37 will rotate clockwise. At this time, the ratchet lever 39 will rotate clockwise along the outside of the ratchet wheel 38, and the ratchet lever 39 will not drive the ratchet wheel 38 to rotate. When the toothed ring 36 rotates clockwise, the control gear 37 will drive the ratchet lever 39 to rotate counterclockwise. At this time, it will drive the ratchet wheel 38 to rotate counterclockwise at the same time. At this time, the first reciprocating lead screw 10 will rotate, driving the scraping ring 11 to slide up and down reciprocally.

[0080] As a preferred embodiment of the present invention, a driving motor 12 is fixedly installed inside the crushing box 3. The output end of the driving motor 12 is fixedly connected to a driving wheel 13. An idle wheel 14 is fixedly installed on the outer wall of the rotating shaft 8. The driving wheel 13 and the idle wheel 14 are connected by a belt.

[0081] The driving motor 12 drives the driving wheel 13 to rotate. Under the action of the belt, it drives the idle wheel 14 to rotate. At this time, the rotating shaft 8 will drive the crushing blades 6 to crush the distillers grains.

[0082] As Figure 11 shown, a method for using an apparatus for efficiently fermenting carbon source from distillers grains. This method uses the above-mentioned apparatus for efficiently fermenting carbon source from distillers grains, including the following steps:

[0083] S1: First, open the feed port 2, and send the distillers grains into the interior of the fermentation barrel 1. The distillers grains enter the interior of the crushing box 3 through the gaps between the multiple shielding sheets 4. Then, by the piston 17 reciprocally sliding inside the air cylinder 16, air is sent into the elastic block 24 to block the gaps between the multiple shielding sheets 4.

[0084] S2: Second, drive the driving wheel 13 and the idle wheel 14 to rotate by the driving motor 12, and control the crushing blades 6 to crush the distillers grains.

[0085] S3: Finally, control the scraping ring 11 to slide down along the interior of the crushing box 3 to scrape off the attached distillers grains. At the same time, use the top pressure rod 15 to press against the C-shaped buckle 31, so that it is withdrawn from the annular card slot 30, releasing the restriction on the blocking frustum 7, and completing the discharge of the distillers grains inside the crushing box 3.

[0086] Working principle: After the wine lees enter the crushing box 3, the driving motor 12 drives the active wheel 13 to rotate, and under the action of the belt, drives the driven wheel 14 to rotate. At this time, the rotating shaft 8 will drive the crushing blade 6 to crush the wine lees. At the same time, the rotating shaft 8 will drive the air ring 25 to rotate, and cooperate with the rotating rod 27 to make the first bevel gear 22 and the second bevel gear 23 engage. The second reciprocating screw 20 will drive the transmission rod 21 and the piston 17 to slide back and forth inside the air cylinder 16. Through cooperation with the first air pipe 18 and the second air pipe 19, the gas can be transported to the inside of the air ring 25, and then enter the inside of the elastic block 24 to fill the gaps of multiple shielding pieces 4 to prevent the wine lees from being thrown out when being crushed.

[0087] After the lees are crushed, by controlling the drive motor 12 to reverse, the positioning ring 5 will drive the gear ring 36 to reverse and drive the control gear 37 to rotate. With the cooperation of the ratchet rod 39 and the ratchet wheel 38, the first reciprocating screw 10 can be driven to rotate. At this time, the scraper ring 11 will slide back and forth up and down along the inside of the crushing box 3 to scrape off the lees attached to the inner wall of the crushing box 3. At the same time, the pressing rod 15 provided at the bottom of the scraper ring 11 can press the top of the C-shaped buckle 31 to release the limit on the blocking cone 7 and complete the unloading of the crushing box 3.

[0088] The above-mentioned front, back, left, right, up and down are all based on the Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
