Description

Technical Field

[0001] This utility model relates to the technical field of cottonseed oil raw material processing, and in particular to a device for coarsely peeling and extracting kernels from cottonseeds for oil extraction. Background Technology

[0002] Cottonseed oil, extracted from cottonseeds, is classified into several types, including pressed cottonseed oil, solvent-extracted cottonseed oil, genetically modified cottonseed oil, crude cottonseed oil, and finished cottonseed oil. It is darker red in color than other oils and, after refining, is edible. It contains a large amount of essential fatty acids and is best consumed mixed with animal fats. To improve the oil yield and quality, cottonseeds need to be dehulled to prevent the outer shell and its lint from affecting the taste and stability of the oil. Existing technology publication number CN24148110U discloses a cottonseed kernel and hull separator, comprising a frame frame with a fixed sealed shell. Inside the frame, three layers of separating screens are arranged from top to bottom: a first separating screen, a second separating screen, and a third separating screen. The separating screens are connected to the frame with snap-on plates. A spiral auger is located below the third separating screen. The frame is equipped with a drive device connected to a stirring rod, which is installed on each layer of separating screens. However, this separator uses particle size for screening, which may not remove some small shells. This may result in too many shells in the kernel, affecting the subsequent leaching effect. When the feed rate is too high, the material may accumulate at the feed point. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cottonseed coarse peeling and kernel extraction device that can gradually feed materials, avoid accumulation, improve separation quality, ensure subsequent leaching effect, and is easy to use.

[0004] This utility model discloses a cottonseed coarse peeling and kernel extraction device for oil extraction, comprising a separation box, a bottom plate, a feeding component, a primary separation component, a separation component, a cotton kernel discharge component, and a cotton hull discharge component. The bottom plate is installed at the bottom of the separation box, the feeding component is installed at the top of the separation box, the primary separation component is installed on the upper side inside the separation box, the separation component is installed on the right side of the separation box, the cotton kernel discharge component is installed on the lower side inside the separation box, and the cotton hull discharge component is installed inside the separation component. Material is gradually added into the separation box through the feeding component to avoid accumulation. The primary separation component performs initial separation of the cotton hull and cotton kernel, and then the separation component performs further separation of the cotton hull to improve separation quality and ensure subsequent leaching effect. The cotton kernel discharge component and the cotton hull discharge component can discharge the cotton hull and cotton kernel respectively.

[0005] Preferably, the feeding assembly includes a mounting block, a feeding cylinder, a feeding head, a rotating shaft, two spiral conveyor blades, and a feeding motor. The mounting block is installed on the top left side of the separation box, and the top of the mounting block is connected to the feeding cylinder. A discharge port communicating with the inside of the feeding cylinder is opened inside the mounting block. The feeding head is connected to the middle of the top of the feeding cylinder. The rotating shaft is rotatably installed inside the feeding cylinder, and spiral conveyor blades are symmetrically installed before and after the rotating shaft. The input end of the rotating shaft is connected to the output end of the feeding motor. When material is added to the feeding head, the feeding motor is started, which drives the two spiral conveyor blades to rotate through the rotating shaft, pushing the material from the middle to both sides, and gradually and evenly entering the separation box through the discharge port to avoid accumulation and improve the separation effect.

[0006] Preferably, the initial separation component includes a first blower, a guide plate, and a separation box. The first blower is installed on the upper left side wall of the separation box, and a guide plate is installed on the right side wall of the separation box. The upper part of the guide plate is a first arc shape, and the lower part of the guide plate is a second semi-circular arc shape. The separation box is installed on the right side wall of the separation box, and an opening is provided on the right side wall of the separation box, which communicates with the interior of the separation box. The first blower is started to blow air onto the falling material. Taking advantage of the difference in specific gravity between cotton kernels and cotton hulls, they are thrown a different distance under the action of wind, separating the kernels and hulls. The hulls fall onto the guide plate and are introduced into the separation box for further processing.

[0007] Preferably, the separation assembly includes a rotating rod, multiple push plates, a bellows, a second fan, and a drive motor. The rotating rod is rotatably mounted on the right end of the separation box. Multiple push plates are axially mounted on the outer wall of the rotating rod, and the push plates slide in a second arc shape with the guide plate. The input end of the rotating rod is connected to the output end of the drive motor. The bellows is installed on the upper left side wall of the separation box, and air inlet slots are opened at both ends of the bellows. The second fan is installed inside the bellows. When the drive motor is started, it drives the rotating rod to rotate, which in turn drives the multiple push plates to rotate, throwing the cotton shells that have slid off the guide plate to the upper right. Because the cotton shells are light, they fly far and fall a long distance, while the cotton kernels are heavy and fall a short distance, thus separating the kernels and shells again. At the same time, the second fan is started to blow air into the separation box. The blowing intensity is less than that of the first fan, further improving the separation effect.

[0008] Preferably, it also includes a connecting pipe and a guide block. The guide block is installed at the bottom of the separation box. The left side of the guide block is connected to the connecting pipe, and the left end of the connecting pipe is connected to the right side wall of the separation box. The separated cotton kernels fall to the left end of the separation box and can be reintroduced into the separation box through the connecting pipe. At the same time, the cotton husks are collected and accumulated at the right end of the separation box.

[0009] Preferably, the cotton kernel discharge assembly includes a receiving seat, a third rotating rod, a third spiral conveyor blade, a second drive motor, and a cotton kernel discharge pipe. The receiving seat is installed inside the ejection box, with a V-shaped upper part and a cylindrical lower part. The third rotating rod is rotatably mounted at the cylindrical lower part of the receiving seat, and a third spiral conveyor blade is installed on the outer wall of the third rotating rod. The input end of the third rotating rod passes through the side wall of the ejection box and connects to the output end of the second drive motor. A cotton kernel discharge pipe is installed on the left side wall of the ejection box. The cotton kernels fall downward onto the upper surface of the receiving seat, and the V-shape of the upper part of the receiving seat guides the cotton kernels towards the center. The second drive motor is started to drive the third rotating rod to rotate, which in turn drives the third spiral conveyor blade to rotate, pushing the cotton kernels to the left and discharging them through the cotton kernel discharge pipe for subsequent processing.

[0010] Preferably, the cotton hull discharge assembly includes a discharge cylinder, a second rotating rod, a second spiral conveyor blade, a discharge pipe, and a motor. The discharge cylinder is installed on the right side of the bottom of the separation box. The second rotating rod is rotatably installed inside the discharge cylinder, and the second spiral conveyor blade is installed on the outer wall of the second rotating rod. The discharge pipe is installed at the rear end of the separation box, and the front end of the second rotating rod is connected to the output end of the motor. When the motor is started, it drives the second rotating rod to rotate, which in turn drives the second spiral conveyor blade to rotate, pushing the cotton hulls accumulated on the right side of the separation box backward and discharging them through the discharge pipe for easy collection and processing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is gradually added into the separation box through the feeding component to avoid accumulation; the cotton hull and cotton kernel are initially separated by the initial separation component; and then the cotton hull is separated again by the separation component to improve the separation quality and ensure the subsequent leaching effect; the cotton kernel discharge component and the cotton hull discharge component can discharge the cotton hull and cotton kernel respectively.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] like Figures 1 to 5As shown, a base plate 2 is installed at the bottom of the release chamber 1, and a mounting block 3 is installed on the top left side of the release chamber 1. A feed cylinder 4 is connected to the top of the mounting block 3, and a discharge port communicating with the inside of the feed cylinder 4 is opened inside the mounting block 3. A feeding head 5 is connected to the middle of the top of the feed cylinder 4. A rotating shaft 6 is rotatably installed inside the feed cylinder 4, and spiral conveying blades 7 are symmetrically installed at the front and rear of the rotating shaft 6. The input end of the rotating shaft 6 is connected to the output end of the feeding motor 8. A first fan 9 is installed on the upper part of the left side wall of the release chamber 1 and on the right side wall of the release chamber 1. A guide plate 10 is installed, with its upper section forming a first arc and its lower section forming a second semi-circular arc. A separation box 13 is installed on the right side wall of the release box 1, with an opening communicating with the interior of the separation box 13. A rotating rod 11 is rotatably mounted on the right end of the release box 1. Multiple push plates 12 are axially mounted on the outer wall of the rotating rod 11, slidingly engaging with the second arc of the guide plate 10. The input end of the rotating rod 11 is connected to the output end of the drive motor 22. A bellows 14 is also present. Installed on the upper left side wall of the separator 13, the air box 14 has air inlet slots at both ends. A second fan 15 is installed inside the air box 14. A guide block 17 is installed at the bottom inside the separator 13. A connecting pipe 16 is connected to the left side of the guide block 17, and the left end of the connecting pipe 16 is connected to the right side wall of the separator 1. A receiving seat 23 is installed inside the separator 1. The upper part of the receiving seat 23 is V-shaped, and the bottom end is cylindrical. A third rotating rod 24 is rotatably installed at the cylindrical position at the bottom end of the receiving seat 23. A third spiral conveyor blade 25 is installed on the outer wall. The input end of the third rotating rod 24 passes through the side wall of the separation box 1 and is connected to the output end of the second drive motor 26. A cotton kernel discharge pipe 27 is installed on the left side wall of the separation box 1. The discharge cylinder 18 is installed on the right side of the bottom end of the separation box 13. A second rotating rod 19 is rotatably installed inside the discharge cylinder 18. A second spiral conveyor blade 20 is installed on the outer wall of the second rotating rod 19. A discharge pipe 21 is installed at the rear end of the separation box 13. The front end of the second rotating rod 19 is connected to the output end of the motor 28.

[0020] Material is added to the feeding head 5. The feeding motor 8 is started, which drives the two spiral conveyor blades 7 to rotate via the rotating shaft 6, pushing the material from the center to both sides. The material gradually and evenly enters the separation box 1 through the discharge port, avoiding accumulation and improving the separation effect. The first blower 9 is started to blow air onto the falling material. Utilizing the difference in specific gravity between cotton kernels and cotton husks, the material is thrown at different distances under the action of the wind, separating the kernels and husks. The husks fall onto the guide plate 10 and are introduced into the separation box 13 for further processing. The drive motor 22 is started to drive the rotating rod 11 to rotate. The rotating rod 11 drives multiple push plates 12 to rotate, throwing the cotton husks that slide off the guide plate 10 to the upper right. Because the cotton husks are light, they fly farther and fall a longer distance, while the cotton kernels are heavier and fall a shorter distance, separating the kernels and husks again. At the same time, the second blower 15 is started to blow air onto the separation box 1. The internal airflow is less intense than that of the first fan 9, further improving the separation effect. The separated cotton kernels fall to the left end of the separation box 13 and can be reintroduced into the separation box 1 through the connecting pipe 16. At the same time, the cotton shells accumulate and are collected at the right end of the separation box 13. The cotton kernels fall downwards onto the upper surface of the receiving seat 23. The V-shaped upper part of the receiving seat 23 guides the cotton kernels towards the center. The second drive motor 26 is started to drive the third rotating rod 24 to rotate. The third rotating rod 24 drives the third spiral conveyor blade 25 to rotate, pushing the cotton kernels to the left and discharging them through the cotton kernel discharge pipe 27 for subsequent processing. The motor 28 is started to drive the second rotating rod 19 to rotate. The second rotating rod 19 drives the second spiral conveyor blade 20 to rotate, pushing the cotton shells accumulated on the right side of the separation box 13 backwards and discharging them through the discharge pipe 21 for easy collection and processing.

[0021] like Figures 1 to 5As shown, this utility model discloses a cottonseed coarse peeling and kernel extraction device for oil extraction. During operation, material is added to the feeding head 5. The feeding motor 8 is started, driving two spiral conveyor blades 7 to rotate via the rotating shaft 6, pushing the material from the center to both sides. The material gradually and evenly enters the separation box 1 through the discharge port, preventing accumulation. The first blower 9 is started to blow air onto the falling material. Utilizing the difference in specific gravity between cotton kernels and cotton hulls, they are thrown at different distances under the action of the wind, separating the kernels and hulls. The hulls fall onto the guide plate 10 and are guided into the separation box 13 for further processing. The drive motor 22 is started, driving the rotating rod 11 to rotate. The rotating rod 11 drives multiple push plates 12 to rotate, throwing the cotton hulls sliding off the guide plate 10 upwards and to the right. Because the cotton hulls are light, they fly farther and fall a longer distance, while the cotton kernels are heavier and fall a shorter distance, thus separating the kernels and hulls again. During separation, the second fan 15 is activated to blow air into the separation box 13. The blowing intensity is less than that of the first fan 9, further improving the separation effect. The separated cotton kernels fall to the left end of the separation box 13 and can be reintroduced into the separation box 1 through the connecting pipe 16. At the same time, the cotton shells accumulate and are collected at the right end of the separation box 13. The cotton kernels fall downward onto the upper surface of the receiving seat 23. The V-shaped upper part of the receiving seat 23 guides the cotton kernels towards the center. The second drive motor 26 is activated to drive the third rotating rod 24 to rotate. The third rotating rod 24 drives the third spiral conveyor blade 25 to rotate, pushing the cotton kernels to the left and discharging them through the cotton kernel discharge pipe 27. The drive motor 28 drives the second rotating rod 19 to rotate, which in turn drives the second spiral conveyor blade 20 to rotate, pushing the cotton shells accumulated on the right side of the separation box 13 backward and discharging them through the discharge pipe 21.
