Description

Technical Field

[0001] This utility model relates to the field of material granulation, specifically to a granulation device for precipitating hydrolysate from plant fiber raw materials. Background Technology

[0002] Plant fiber raw materials are renewable biomass raw materials. Using them as raw materials, monosaccharides can be obtained through hydrolysis, and then processed through fermentation or chemical processes to produce feed protein, food, and chemical products, thus reducing carbon emissions. Chinese patent CN200710030294.2 solved the problem of preparing hydrolysate from concentrated acid in plant fiber raw materials, and Chinese patent CN200810145571.9 solved the problem of sugar-acid separation in concentrated acid hydrolysate of plant fiber raw materials. In the sugar-acid separation process, to accelerate the separation, the hydrolysate precipitate needs to be transformed from a large lump into small particles. However, before granulation, the hydrolysate precipitate is a soft, dough-like semi-solid state rich in sulfuric acid, increasing the difficulty of equipment selection. Therefore, a dedicated hydrolysate precipitation and granulation device needs to be developed. Summary of the Invention

[0003] To overcome the shortcomings and deficiencies of existing technologies, the purpose of this utility model is to provide a granulation device for the precipitation of plant fiber raw material hydrolysate. The device has a simple structure. The feeding component is used for feeding the plant fiber raw material hydrolysate and forming the precipitate into thin sheets. The granulation component is used for granulating the thin sheet-like plant fiber raw material hydrolysate. The feeding component and the granulation component work together to eliminate the need for manual feeding and pressing, thereby reducing the burden of manpower and improving work efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A granulation device for precipitating hydrolysate from plant fiber raw materials includes a feeding assembly and a granulation assembly arranged sequentially from top to bottom. The granulation assembly includes a granulation roller and a counter-pressure roller arranged horizontally. The axis of the granulation roller and the axis of the counter-pressure roller are parallel. The granulation roller is covered with a granulation mold in a circumferential direction. The side of the counter-pressure roller abuts against the granulation mold, and the upper end of the counter-pressure roller at the point of contact with the granulation mold layer forms a feed inlet. The feeding assembly includes multiple sets of guide rollers arranged sequentially from top to bottom. Each set of guide rollers includes a first guide roller and a second guide roller arranged horizontally. The axes of the first guide roller and the second guide roller are parallel. A gap communicating with the feed inlet is left between the first guide roller and the second guide roller. The multiple gaps arranged sequentially from top to bottom form a feeding channel communicating with the feed inlet. The diameter of the feeding channel gradually decreases from top to bottom.

[0006] Furthermore, the surface of the pelletizing mold is provided with multiple material placement grooves.

[0007] Furthermore, the cross-section of the feeding trough along the tangent direction of the granulation roller is at least one of a triangle, a square, or a hexagon.

[0008] Furthermore, the pelletizing assembly also includes a scraper located at the lower end of the contact point between the pressure roller and the pelletizing die, the blade of the scraper abutting against the surface of the pelletizing die.

[0009] Furthermore, the granulation device for precipitating hydrolysate of plant fiber raw materials also includes a material flushing assembly located on one side of the granulation roller. The material flushing assembly includes a guide plate, a spray pipe, and a precipitant tank connected to the spray pipe. The water outlet of the spray pipe is located at the upper end of the water inlet of the guide plate, and the water outlet of the guide plate is located on one side of the granulation mold.

[0010] Furthermore, the outer surfaces of the first inlet roller, the second inlet roller, the granulation roller, and the counter-pressure roller are coated with a layer of polymer material.

[0011] Furthermore, the outer surface of the scraper is covered with a layer of polymer material, or the scraper is made of polymer material.

[0013] Furthermore, bearing seats are provided at both ends of the roller shafts of the first inlet roller, the second inlet roller, the granulation roller, and the counterweight roller.

[0014] Furthermore, a drive wheel is provided at one end of the roller shafts of the first inlet roller, the second inlet roller, the granulation roller, and the counterweight roller.

[0015] The beneficial effects of this utility model are as follows: The granulation device for the precipitation of plant fiber raw material hydrolysate has a simple structure. The material guiding component gradually reduces the gap between the first and second inlet rollers in multiple sets of inlet roller groups from top to bottom, so that the hydrolysate precipitate gradually becomes thinner after being pressed by multiple sets of inlet roller groups, making the hydrolysate precipitate into a thin sheet suitable for granulation. The granulation component presses the thin sheet-like hydrolysate precipitate into the granulation mold of the granulation roller through the pressing action of the pressure roller. The granulation mold forms the thin sheet-like hydrolysate precipitate into individual hydrolysate granules, completing the granulation process.

Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0022] like Figure 1-2 As shown, a granulation device for precipitating hydrolysate from plant fiber raw materials includes a feeding assembly 2 and a granulation assembly 1 arranged sequentially from top to bottom. The granulation assembly 1 includes a granulation roller 11 and a counter-pressure roller 13 arranged horizontally. The axis of the granulation roller 11 and the axis of the counter-pressure roller 13 are parallel. The granulation roller 11 is covered with a granulation mold 12 in a circumferential direction. The surface of the counter-pressure roller is flat and smooth. The side of the counter-pressure roller 13 abuts against the granulation mold 12, and the upper end of the contact point between the counter-pressure roller 13 and the granulation mold 12 forms a feed inlet 15. The feeding assembly 2 includes multiple sets of guide roller groups arranged sequentially from top to bottom. Each guide roller group includes a first guide roller 21 and a second guide roller 22 arranged horizontally. The axis of the first guide roller 21 and the axis of the second guide roller 22 are parallel to each other. The axes of rollers 22 are arranged in parallel. A gap 23 is left between the first guide roller 21 and the second guide roller 22. Multiple gaps 23 arranged sequentially from top to bottom form a guide channel 24. The guide channel 24 is connected to the inlet 15. The diameter of the guide channel 24 gradually decreases from top to bottom. That is, the distance of the gap 23 between the first guide roller 21 and the second guide roller 22 in the multiple sets of guide rollers gradually decreases from top to bottom. The upper end of the guide channel 24 is the guide port, and the lower end of the guide channel 24 is the guide outlet. That is, the gap 23 between the first guide roller 21 and the second guide roller 22 in the uppermost guide roller group is the inlet and outlet, and the gap 23 between the first guide roller 21 and the second guide roller 22 in the lowermost guide roller group is the outlet.

[0023] This utility model discloses a granulation device for the precipitation of plant fiber raw material hydrolysate. The device has a simple structure. The feeding component 2 is used for feeding the plant fiber raw material hydrolysate and forming it into thin sheets. The granulation component 1 is used for granulating the thin sheet-like plant fiber raw material hydrolysate. The feeding component 2 and the granulation component 1 work together, eliminating the need for manual feeding and pressing, thus reducing manpower and improving work efficiency. Specifically, the gap 23 between the first guide roller 21 and the second guide roller 22 in the multiple sets of guide rollers gradually decreases from top to bottom. The flow rate gradually decreases, causing the hydrolysate precipitate to become thinner as it passes through multiple sets of inlet rollers. This thin sheet-like hydrolysate precipitate is then fed into the space between the granulation mold 12 and the pressure rollers via the inlet 15. The pressure rollers press the thin sheet-like hydrolysate precipitate into the granulation mold 12, where it is formed into individual hydrolysate precipitate particles, completing the granulation process. Finally, as the granulation rollers rotate, the formed hydrolysate precipitate particles fall from the granulation mold 12 under the influence of gravity and detach from the granulation rollers. The operation is simple, stable, and reliable.

[0024] It should be noted that the distance between the lower end face of the first inlet roller 21 located at the upper end and the upper end face of the first inlet roller 21 in the adjacent lower inlet roller group is very short, so that the hydrolysate precipitate cannot be separated from the feed channel 24 between the first inlet rollers 21; and the distance between the lower end face of the second inlet roller 22 located at the upper end and the upper end face of the second inlet roller 22 in the adjacent lower inlet roller group is very short, so that the hydrolysate precipitate cannot be separated from the feed channel 24 between the second inlet rollers 22; and the distance between the lower end face of the first inlet roller 21 in the lowest inlet roller group and the surface of the granulation mold 12 is very short, and the distance between the lower end face of the second inlet roller 22 in the lowest inlet roller group and the surface of the pressure roller 13 is also very short, so that the hydrolysate precipitate cannot be separated from the feed inlet 15.

[0025] Furthermore, the granulation mold 12 has multiple material placement grooves 121 on its surface. Through the pressing action of the pressure roller, the thin sheet-like hydrolysate is pressed into the material placement grooves 121 of the granulation mold 12 to complete the granulation process. Preferably, the material placement groove 121 is a through groove that runs through the granulation mold 12 from the outside to the inside, so that the solution flows out after the thin sheet-like hydrolysate is pressed by the pressure roller.

[0026] Furthermore, such as Figure 3 As shown, the cross-section of the material feeding trough 121 along the tangent direction of the granulation roller 11 is at least one of a triangle, a square, or a hexagon. Preferably, the cross-section of the material feeding trough 121 along the tangent direction of the granulation roller 11 is at least one of a right-angled equilateral triangle, an equilateral triangle, a square, or a regular hexagon. The appropriate cross-sectional shape can be selected as needed.

[0027] Furthermore, the granulation assembly 1 also includes a scraper 14 located at the lower end of the contact point between the pressure roller 13 and the granulation mold 12. The blade of the scraper 14 abuts against the surface of the granulation mold 12. The scraper 14 is used to scrape off the hydrolysate precipitate that did not enter the granulation mold 12 during the forming process, so as to prevent the formed particles in the granulation mold 12 from sticking together with the hydrolysate precipitate that did not enter the granulation mold 12, thereby forming independent and unconnected hydrolysate precipitate particles.

[0028] Furthermore, the granulation device for precipitating hydrolysate from plant fiber raw materials also includes a flushing assembly 3 located on one side of the granulation roller 11. The flushing assembly 3 includes a guide plate 31, a spray pipe 32, and a precipitant tank 33 connected to the spray pipe 32. The water outlet of the spray pipe 32 is located above the water inlet of the guide plate 31, and the water outlet of the guide plate 31 is located on one side of the granulation mold 12. Specifically, the precipitant tank 33 contains a precipitant, which continuously flows from the precipitant tank 33 into the spray pipe 32, and then is sprayed from the spray pipe 32 through the guide plate 31 onto the granulation mold 12 on the surface of the granulation roller. This washes away the hydrolysate precipitates that have not fallen off under gravity and carries them away from the granulation mold 12. At the same time, the granulation roller returns to its initial state.

[0029] Furthermore, the outer surfaces of the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counter-pressure roller 13 are coated with a polymer material layer. In this embodiment, the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counter-pressure roller 13 are made of metal, and their outer surfaces are coated with a polymer material layer. This polymer material layer is used to prevent sulfuric acid in the hydrolysate from corroding the metal, thus extending the service life of the granulation device.

[0030] Furthermore, the outer surface of the scraper 14 is coated with a polymer material layer. In this embodiment, the scraper 14 is made of metal, and the polymer material layer on its outer surface prevents sulfuric acid in the hydrolysate from corroding the metal. In another embodiment, the scraper 14 is made of a polymer material to prevent sulfuric acid in the hydrolysate from corroding the scraper 14, thus extending the service life of the granulation device.

[0031] Furthermore, the polymer material layer is made of a polymer material, wherein the polymer material is an existing material, and the polymer material is composed of at least one of acid-resistant plastics or rubber. The acid-resistant plastic is at least one of polypropylene, polyethylene, phenolic resin, and furfuryl alcohol resin.

[0032] Furthermore, bearing seats 4 are provided at both ends of the roller shafts of the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counterweight roller 13. The bearing seats 4 are used to ensure that the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counterweight roller 13 remain stable during rotation and avoid deviation or vibration.

[0033] Furthermore, a transmission wheel 5 is provided at one end of the roller shafts of the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counterweight roller 13. The transmission wheel 5 is located outside the bearing. In this embodiment, at least one of the roller shafts corresponding to the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counterweight roller 13 serves as a drive shaft and is connected to the motor reducer 6. The transmission wheel 5 on the drive shaft drives the transmission wheels 5 on the other roller shafts through a transmission mechanism. The transmission mechanism adopts a prior art transmission mechanism, which can be a gear transmission mechanism. During the rotation of the first inlet roller 21, the second inlet roller 22, the granulation roller 11, and the counter-pressure roller 13, the first inlet roller 21 rotates clockwise toward the second inlet roller 22, and the second inlet roller 22 rotates counterclockwise toward the first inlet roller 21. That is, both the first inlet roller 21 and the second inlet roller 22 rotate toward the direction of hydrolysate precipitation, which facilitates the hydrolysate precipitation to move toward the gap 23 between the first inlet roller 21 and the second inlet roller 22 in the inlet roller group located at its lower end, and gradually become thinner. The granulation roller 11 rotates clockwise toward the counter-pressure roller 13, and the counter-pressure roller 13 rotates counterclockwise toward the granulation roller 11. That is, both the granulation roller 11 and the counter-pressure roller 13 rotate toward the direction of hydrolysate precipitation, which facilitates the movement of the thin sheet-like hydrolysate precipitation between the granulation roller 11 and the counter-pressure roller 13. Through the pressure of the pressure roller, the thin sheet-like hydrolysate precipitation enters the granulation mold 12 of the granulation roller for granulation.

[0034] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
