Description
Technical Field
[0001] This utility model relates to the technical field of citrus seed processing equipment, and in particular to a citrus seed separation system. Background Technology
[0002] Citrus fruits, including oranges, grapefruits, and tangerines, are characterized by their peel and segmented pulp. In breeding, the peel needs to be removed, the pulp broken up, and the seeds separated before further cleaning. Current techniques typically involve removing the peel first, then feeding the pulp into a crusher to break it down before separating the seeds. However, in practice, the seeds may be damaged by the crushing process, resulting in a low percentage of intact seeds. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a citrus seed separation system that solves the problem that citrus seeds may be damaged by crushing in existing technologies.
[0004] According to an embodiment, a citrus seed separation system is provided, which includes a separation tank and a compression separation tube fixedly installed above the separation tank. The compression separation tube extends laterally and has a first mounting shaft coaxially rotating inside it. A first drive motor for driving the first mounting shaft is installed at one end of the compression separation tube, and a slag discharge pipe is installed at the other end. A feed hopper is fixedly connected to the end of the compression separation tube where the first drive motor is installed. A compression screw is also fixedly installed on the first mounting shaft. The compression separation tube is also provided with a plurality of first through holes located directly above the separation tank and directly below the compression screw. A water inlet pipe and a water outlet pipe are also provided at its upper end and bottom of the separation tank. The separation tank is also provided with a slag removal port that is offset from the compression separation tube. In this solution, peeled citrus pulp is fed into the hopper and moved to the other end by the extrusion screw. During the process, the pulp is crushed by the extrusion screw. The citrus seeds can pass through the first perforation into the separation tank below, while the remaining pulp can enter the slag discharge pipe and be discharged. The extrusion screw causes less damage to the citrus seeds during the process, so the obtained citrus seeds have a higher integrity rate. This solves the problem that the crusher in the prior art may cause the citrus seeds to be agitated and damaged.
[0005] Furthermore, a first partition, a second partition, and a third partition are fixedly connected inside the extrusion separation tube, dividing the extrusion spiral into a first extrusion section, a second extrusion section, and a third extrusion section with gradually decreasing pitch. The first mounting shaft rotates through the first partition, the second partition, and the third partition, and the first partition, the second partition, and the third partition are respectively provided with a plurality of second perforations, a plurality of third perforations, and a plurality of fourth perforations with gradually decreasing inner diameters, and the inner diameter of the fourth perforation is larger than that of the first perforation.
[0006] Furthermore, the first perforation is located between the first partition, the second partition, and the third partition.
[0007] Furthermore, a return trough is provided on the side of the separation tank away from the slag outlet. A connecting channel and a guide plate inclined through the connecting channel are provided between the return trough and the separation tank. The higher end of the guide plate is located in the separation tank and the lower end is located in the return trough.
[0008] Furthermore, the drain pipe is located below the higher end of the guide plate, and the higher end of the guide plate is also provided with a fifth perforation.
[0009] Furthermore, a fourth partition is fixedly connected to the lower end of the guide plate, and a sixth perforation is provided on the fourth partition.
[0010] Furthermore, a second mounting shaft extending laterally is also provided inside the separation tank, and a second drive motor for driving the second mounting shaft is also provided outside the separation tank. An agitating spiral is also fixedly provided on the second mounting shaft.
[0011] Furthermore, the stirring spiral is located below the slag extraction port and above the fifth perforation.
[0012] Furthermore, the separation tank is also fixedly connected to a slag discharge trough, and an overflow port is provided between the slag discharge trough and the slag removal port.
[0013] Furthermore, the end of the slag discharge pipe that is away from the extrusion separation pipe extends above the slag discharge trough.
[0014] Compared with the prior art, the present invention has the following beneficial effects: An extrusion screw is installed inside the extrusion separation tube to extrude the peeled citrus pulp, so that the citrus seeds pass through the first perforation into the separation tank, while the remaining pulp is discharged from the slag discharge pipe. During the process, the extrusion screw causes less damage to the citrus seeds, so the obtained citrus seeds have a higher integrity rate, which solves the problem that the crusher may cause the citrus seeds to be agitated and damaged in the existing technology. Water is filled into the separation tank. The remaining pulp that comes into the tank with the citrus seeds will float to the surface and can be scooped out through the pulp outlet, while the citrus seeds will sink to the bottom, thus enabling more efficient collection of citrus seeds.

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 , 2As shown, this embodiment provides a citrus seed separation system, which includes a separation tank 1 and a return tank 2, which share a common wall 3. A connecting channel 4 is provided at the lower end of the common wall 3 to connect the separation tank 1 and the return tank 2. A laterally extending extrusion separation tube 5 is fixedly connected above the separation tank 1. A first mounting shaft 6 is coaxially arranged inside the extrusion separation tube 5. A first drive motor 7 that drives the first mounting shaft 6 to rotate is fixedly arranged outside one end of the extrusion separation tube 5. A slag discharge pipe 8 connected to the other end of the extrusion separation tube 5 is provided. A slag discharge pipe located at the separation tank is also provided on the extrusion separation tube 5. Multiple first perforations 9 are located directly above the first mounting shaft 6. A compression screw extending from one end of the compression separation tube 5 to the other is fixedly connected to the first mounting shaft 6. A feed hopper 10 is fixedly connected above the end of the compression separation tube 5 near the first drive motor 7. Peeled citrus pulp can be introduced through the feed hopper 10. As the first drive motor 7 runs, the compression screw pushes the citrus pulp toward the slag discharge pipe 8. During the movement, the citrus pulp is compressed and broken. Citrus seeds in the pulp can pass through the first perforations 9 into the separation tank 1 below, while the remaining pulp can enter the slag discharge pipe. 8. Then, the seeds are exported. During the process, the squeezing spiral causes less damage to the citrus seeds, resulting in a higher integrity rate. This solves the problem that the crusher in the prior art may cause damage to the citrus seeds. A water inlet pipe 11 is fixedly connected to the separation tank 1 and located at its upper end to introduce clean water. A drain pipe 12 is also provided at the bottom of the separation tank 1. The citrus seeds carry a lot of pulp with them when passing through the first perforation 9. In the separation tank 1, the pulp floats on the water surface, while the citrus seeds sink to the bottom, thus achieving separation. Furthermore, the separation tank 1 is also equipped with... The pulp can be scooped out of the pulp outlet 13, which is offset from the extrusion separation pipe 5. After the pulp is processed, the water can be drained through the bottom drain pipe 12 to remove the citrus seeds. In this solution, an inclined guide plate 14 is also provided. The higher end of the guide plate 14 is located in the separation tank 1. The guide plate 14 extends obliquely downward through the connecting channel 4 and into the return tank 2. In this way, the citrus seeds will fall onto the guide plate 14 and then pass obliquely downward through the connecting channel 4 into the return tank 2. This makes it easier to collect the citrus seeds in the return tank 2.
[0018] like Figure 1 , 2As shown, a first partition 15, a second partition 16, and a third partition 17 are fixedly installed from one end to the other inside the extrusion separation tube 5, and each partition has multiple second through holes, multiple third through holes, and multiple fourth through holes 18. Simultaneously, the first mounting shaft 6 rotates through the first partition 15, the second partition 16, and the third partition 17. The extrusion screw also includes a first extrusion section 19 and a second extrusion section 20 located on both sides of the first partition 15, and a third extrusion section 21 located between the second partition 16 and the third partition 17. That is, the citrus pulp introduced through the feed hopper 10 is extruded through the second through holes by the first extrusion section 19 and then enters the second extrusion section. The pulp is compressed in section 20, then passes through the third perforation into the third compression section 21, and finally passes through the fourth perforation 18 to be discharged into the slag discharge pipe 8. Furthermore, the inner diameters of the second, third, and fourth perforations 18, as well as the first perforation 9, gradually decrease. During the process, the pulp mainly passes through the second, third, and fourth perforations 18, while some pulp, mixed with citrus seeds, passes through the first perforation 9 (the inner diameter of the first perforation 9 is larger than the normal size of citrus seeds, such as 5-8 mm) into the separation tank 1 below. Even further, the first perforation 9 is located between the first partition 15, the second partition 16, and the third partition 17, i.e., in the first compression section... In section 19, all the pulp and citrus seeds pass through the second perforation. Only in the second extrusion section 20 and the third extrusion section 21 does some pulp, mixed with citrus seeds, pass through the first perforation 9. That is, in the first extrusion section 19, the pulp is mainly crushed. In the subsequent second extrusion section 20 and the third extrusion section 21, as the pulp continues to be crushed, the citrus seeds are separated. In particular, the first perforation 9 can be arranged in an arc shape and extend laterally on the bottom wall of the extrusion separation tube 5. In this way, during the spiral pushing process of pulp and citrus seeds, some pulp mixed with citrus seeds can pass through the first perforation 9 into the separation groove 1 below. Furthermore, the first extrusion section 19, the second extrusion section 20, and the third extrusion section 21 are designed to... The pitch of section 21 gradually decreases, meaning that the squeezing force on the pulp gradually increases as it spirals through the extrusion separation tube 5, thus more efficiently squeezing the citrus seeds into the separation groove 1 below. Furthermore, as the pulp passes through the second and third perforations, it is also subjected to shearing forces that tear it, allowing the citrus seeds in the pulp to come out smoothly. More specifically, the outer periphery of the first partition 15, the second partition 16, and the third partition 17 are all recessed to form corresponding second, third, and fourth perforations 18, so that the pulp on the tube wall of the separation tube can smoothly pass through the first partition 15, the second partition 16, and the third partition 17 during the advancement process.
[0019] like Figure 1 , 3As shown, the third baffle 17 can be located at the end of the extrusion separation tube 5, that is, the slag discharge tube 8 is fixed to the third baffle 17. After the pulp passes through the fourth perforation 18, it goes directly into the slag discharge tube 8 and is smoothly discharged. Furthermore, in this solution, an overflow port 22 can be set at the slag outlet 13. Clean water is continuously introduced through the water inlet pipe 11. The water overflows from the overflow port 22, so that the pulp floating on the water surface in the separation tank 1 will also be discharged with the overflow, so as to avoid the need for operators to manually pick it up. Furthermore, a slag discharge trough 23 located outside the separation tank 1 and connected to the overflow port 22 can be fixedly connected to it. The overflowed pulp is finally guided away through the slag discharge trough 23. In a further solution, the end of the slag discharge tube 8 away from the extrusion separation tube 5 can extend above the slag discharge trough 23, so that the pulp discharged through the extrusion separation tube 5 can also be discharged together with the slag discharge trough 23.
[0020] like Figure 1 and 4As shown, the drain pipe 12 is located below the higher end of the guide plate 14, and the higher end of the guide plate 14 is also provided with a fifth perforation 24. The fifth perforation 24 is also located on both sides of the third partition 17, separate from the third extrusion section 21. That is, the citrus seeds falling into the separation tank 1 will not directly reach the fifth perforation 24. At the same time, the fifth perforation 24 can be made smaller to prevent the citrus seeds from passing through. In actual operation, the drain pipe 12 at the bottom can be opened so that some water is discharged from the drain pipe 12 and some water is discharged from the overflow port 22, so that the water volume of the inlet pipe 11 is greater than the water volume of the drain pipe 12. In this way, there is a first water flow path flowing towards the overflow port 22 and a second water flow path flowing through the fifth perforation 24 towards the drain pipe 12 in the separation tank 1. Under the coordination of the first and second water flow paths, the overall water flow is directed towards the overflow outlet 22, allowing the pulp to pass through the overflow outlet 22 more efficiently. The citrus seeds are also affected by the overall water flow and flow towards the overflow outlet 22, but they will sink and, guided by the second water flow path, may fall onto the higher end of the guide plate 14. In a further embodiment, a fourth partition 25 is fixedly connected to the lower end of the guide plate 14. The fourth partition 25 has a sixth perforation 26, meaning the bottom of the guide plate 14 and the return trough 2 are separated. The fourth partition 25 supports the end of the guide plate 14, thus forming a recessed space 27 at the bottom of the return trough 2, located outside the end of the guide plate 14. This allows for the extrusion separation tube 5 to... After all the pulp in the fruit is discharged outside the extrusion separation tube 5, clean water is continuously supplied so that all the pulp floating on the water surface is discharged through the overflow port 22 (the remaining pulp can also be manually scooped out to save time). Then the water supply to the inlet pipe 11 can be turned off, and only the water in the separation tank 1 is discharged through the drain pipe 12. In this way, the water is generally downward and also has a third water flow path along the guide plate 14 and then through the sixth perforation 26 to the drain pipe 12. In this way, the citrus seeds falling on the guide plate 14 will reach the concave space 27 more efficiently. The sixth perforation 26 is designed so that the citrus seeds cannot pass through, thus intercepting the citrus seeds in the concave space 27. After the water level is lower than the fifth perforation 24, only the third water flow path exists, which can guide the seeds to the concave space 27. All the citrus seeds on the feed plate 14 are guided into the recessed space 27. In a further embodiment, a collection basket 28 can be placed in the recessed space 27. The collection basket 28 allows water to pass through and can intercept the citrus seeds. The upper end of the collection basket 28 is lower than the lower end of the feed plate 14 and one side abuts against the fourth partition 25. This allows the citrus seeds to go directly into the collection basket 28, making it easier to remove them later. In a more detailed embodiment, the lower end of the feed plate 14 extends above the opening of the collection basket 28, allowing the citrus seeds to reach the collection basket 28 more smoothly. At the same time, the collection basket 28 is lower than the lower end of the feed plate 14 and there is a gap between the collection basket 28 and the inner wall of the return trough 2, so that the collection basket 28 can be easily picked up and put in.
[0021] like Figure 1As shown, an agitator spiral 29 is also installed in the separation tank 1. The agitator spiral 29 is fixed on a second mounting shaft 30. The second mounting shaft 30 extends laterally and one end rotates to the outside of the separation tank 1, where it is connected to a second drive motor 31 that drives its rotation. The agitator spiral 29 is located below the water surface. When the second drive motor 31 runs, the agitator spiral 29 can agitate the water, thereby enabling the pulp and citrus seeds in the separation tank 1 to be separated more efficiently. Furthermore, the other end of the second mounting shaft 30 can be rotatably connected to the common wall 3, and the agitator spiral 29 can be positioned at the residue removal point. Between the opening 13 and the fifth perforation 24, the agitation is more concentrated in the separation tank 1 near the overflow port 22. When the second drive motor 31 is running, the agitating spiral 29 can pull the water flow towards the overflow port 22 by rotating. At the same time, it assists the water flow towards the overflow port 22. Meanwhile, during operation, some pulp and citrus seeds may be tightly bound together and will flow downward with the second water flow path. In this way, the second water flow path will directly pass through the agitating spiral 29 and its vicinity, and the pulp will be agitated to a greater extent, thus completely separating it from the citrus seeds and achieving more thorough separation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
