Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural product processing equipment technology, and in particular to a device and method for cleaning and removing impurities from oilseed raw materials. Background Technology
[0002] After harvesting, oilseeds such as rapeseed are often mixed with impurities such as stones, broken leaves, and empty seeds. These impurities not only affect the oil yield and quality during subsequent pressing, but the hard particles can also severely wear down processing equipment. Therefore, oilseeds must be cleaned and impurities removed before entering the oil pressing process.
[0003] Current technology typically uses air separation to sieve out impurities such as stones, broken leaves, and empty seeds. However, for stones with a particle size similar to plump rapeseed seeds, which cannot be effectively separated in the airflow due to density differences alone, air separation is clearly insufficient. These stones will enter the subsequent oil pressing process along with the rapeseed, causing severe wear and tear on the equipment and directly reducing the oil yield and oil quality.

[0029] Furthermore, the sorting trough 2 is fixedly installed on the top of the base 1; the partition 3 is fixedly installed inside the sorting trough 2, and the partition 3 divides the internal space of the sorting trough 2 into a first settling zone 201 and a second settling zone 202; the perforated collection basket 4 is installed inside the first settling zone 201; and the receiving mechanism 5 is installed below the sorting trough 2 and communicates with the second settling zone 202. The feeding chute 6 is fixedly installed on one side of the sorting tank 2; the impurity removal chute 7 is fixedly installed on the side of the sorting tank 2 away from the feeding chute 6; the feeding mechanism 8 is installed on the top of the base 1 and is used to continuously feed the rapeseed to be cleaned and impurities removed into the feeding chute 6; the water supply mechanism 9 is installed on the top of the base 1 and is used to continuously inject high-speed water into the feeding chute 6.
[0030] In this embodiment, the sorting tank 2 is used to hold water, providing space for the hydraulic separation of rapeseed. The top of the partition 3 is lower than the water surface, dividing the internal space of the sorting tank 2 into a first settling zone 201 and a second settling zone 202 along the material flow direction. The first settling zone 201 is used to receive the newly injected slurry and allow stones to settle quickly, while the second settling zone 202 is used for the slow settling of plump rapeseed. The perforated collection basket 4 has multiple water-permeable holes at its bottom and is designed as a liftable structure so that it can be removed from the sorting tank 2 for cleaning after it is full. The receiving mechanism 5 is used to collect and discharge the plump rapeseed after it has slowly settled into the second settling zone 202. The feeding chute 6 is inclined. The water supply mechanism 9 is used to continuously inject high-speed water into the feeding chute 6. The feeding mechanism 8 is used to continuously feed the rapeseed to be cleaned and impurities removed into the feeding chute 6. The rapeseed to be cleaned and impurities removed is mixed with high-speed water flow in the feeding chute 6 to form a slurry. The impurity discharge chute 7 is used to allow light impurities floating on the water surface to flow out with the water flow.
[0031] In operation, the sorting tank 2 is filled with water; the water supply mechanism 9 is activated to continuously inject high-speed water into the feeding chute 6; the feeding mechanism 8 is activated to continuously feed the rapeseed to be cleaned and impurities removed into the feeding chute 6, forming a slurry under the influence of the water flow, which quickly flows into the sorting tank 2; stones in the slurry settle rapidly in the first settling zone 201 and are collected in the perforated collection basket 4; plump rapeseed in the slurry passes over the partition 3 and slowly settles in the second settling zone 202, and is collected by the receiving mechanism 5; empty rapeseed and floating impurities float on the water surface and flow out from the impurity discharge chute 7 with the water flow. In water sorting, the difference in settling speed between stones and rapeseed is greater, making them easier to separate. This solves the problem that existing air separation technology cannot effectively remove stones.
[0032] Furthermore, the V-shaped receiving hopper 501 is fixedly installed at the bottom of the sorting tank 2 and communicates with the second settling zone 202; the bottom of the V-shaped receiving hopper 501 is cylindrical; the pushing member 502 is installed on the V-shaped receiving hopper 501 and is used to push the rapeseed towards the side outlet of the V-shaped receiving hopper 501; the displacement member 503 is fixedly installed on the top of the base 1; the U-shaped frame 504 is installed on one side of the displacement member 503; the L-shaped pipe 505 is fixedly installed on one side of the U-shaped frame 504; the lateral opening of the L-shaped pipe 505 abuts against the side outlet of the V-shaped receiving hopper 501; the filter screen 506 is fixedly installed in the lateral opening of the L-shaped pipe 505; the end cap 507 is threaded onto the vertical outlet of the L-shaped pipe 505; the displacement member 503 is used to drive the L-shaped pipe 505 to move.
[0033] In this embodiment, the V-shaped receiving hopper 501 is used to receive plump rapeseed seeds settling from the second settling zone 202 to the bottom. Its bottom is designed to be cylindrical to match the shape of the pushing member 502, reducing dead angles in the pushing process. The pushing member 502 is disposed within the cylindrical bottom of the V-shaped receiving hopper 501 and is used to continuously push the settled rapeseed seeds towards the side outlet of the V-shaped receiving hopper 501, achieving forced discharge and preventing rapeseed accumulation and blockage. The displacement member 503 is fixedly disposed on the top of the base 1 and is used to provide driving force for linear reciprocating motion. The U-shaped frame 50... 4 is disposed on one side of the displacement member 503 and driven to move by the displacement member 503, for fixing and supporting the L-shaped pipe 505; the L-shaped pipe 505 is fixedly disposed on one side of the U-shaped frame 504, and its lateral opening abuts against the side outlet of the V-shaped receiving hopper 501, and a sealing ring can be provided for sealing; the filter screen 506 is fixedly disposed in the lateral opening of the L-shaped pipe 505 to achieve solid-liquid separation; the displacement member 503 drives the L-shaped pipe 505 to move, for achieving abutment or separation between the lateral opening of the L-shaped pipe 505 and the side outlet of the V-shaped receiving hopper 501. After sorting, the end cap 507 is rotated and opened, the water in the second settling zone 202 is discharged, and the rapeseed is intercepted by the filter screen 506. After all the water is discharged, the displacement member 503 is used to move the L-shaped pipe 505 away from the side outlet of the V-shaped receiving hopper 501. Then, under the action of the pusher 502, the rapeseed is pushed out from the side outlet of the V-shaped receiving hopper 501 one after another.
[0034] Furthermore, the rotating shaft 50201 is rotatably disposed at the bottom of the V-shaped receiving hopper 501; the spiral blade 50202 is fixedly disposed on the rotating shaft 50201; the first motor 50203 is fixedly disposed on one side of the V-shaped receiving hopper 501, and the output end of the first motor 50203 is fixedly connected to the rotating shaft 50201.
[0035] In this embodiment, the first motor 50203 drives the rotating shaft 50201 to rotate the spiral blade 50202, continuously pushing the rapeseed deposited at the bottom of the V-shaped receiving hopper 501 towards the side outlet. Furthermore, the first bracket 50301 is fixedly mounted on the top of the base 1; the two crossbars 50302 are fixedly connected to the U-shaped frame 504 and slidably connected to the first bracket 50301, and pass through the first bracket 50301; the hydraulic cylinder 50303 is fixedly mounted on the first bracket 50301, and the output end of the hydraulic cylinder 50303 is fixedly connected to the U-shaped frame 504.
[0036] In this embodiment, the two crossbars 50302 are used to guide the U-shaped frame 504 to move smoothly along a straight line; the hydraulic cylinder 50303 is used to drive the U-shaped frame 504 and the L-shaped pipe 505 to move forward or backward together, so as to achieve the abutment or separation of the lateral opening of the L-shaped pipe 505 with the side outlet of the V-shaped receiving hopper 501.
[0037] Furthermore, multiple sliding rods 50801 are slidably connected to the L-shaped pipe 505 and pass through the L-shaped pipe 505; each sliding rod 50801 is fixedly provided with a striking head 50802 at one end near the filter screen 506; each sliding rod 50801 is fitted with a spring 50803; the synchronizing block 50804 is fixedly provided at one end of multiple sliding rods 50801 away from the filter screen 506; the mounting shaft 50805 is rotatably mounted on the U-shaped frame 504; the rotating block 50806 is fixedly mounted on the mounting shaft 50805; multiple toggle blocks 50807 are fixedly mounted equidistantly on the rotating block 50806 in the circumferential direction; the second motor 50808 is fixedly mounted on one side of the U-shaped frame 504, and the output end of the second motor 50808 is fixedly connected to the mounting shaft 50805.
[0038] In this embodiment, the second motor 50808 drives the mounting shaft 50805 to rotate, thereby causing the rotating block 50806 and its plurality of toggle blocks 50807 to rotate synchronously; when a certain toggle block 50807 rotates with the rotating block 50806 to contact the synchronizing block 50804, the toggle block 50807 pushes the synchronizing block 50804, thereby causing the plurality of slide rods 50801 together with the striking head 50802 to move away from the filter screen 506. At this time, the spring 50803 sleeved on the slide rod 50801 is compressed to accumulate elastic potential energy; the toggle block 50807... 7. As the rotation continues, the spring 50803 disengages from the synchronization block 50804, releasing its accumulated elastic potential energy and pushing the slide rod 50801 and the striking head 50802 to quickly return to their original position towards the filter screen 506. During the return process, the striking head 50802 strikes the filter screen 506, causing the rapeseed adhering to the screen surface to be shaken off, preventing clogging of the mesh. As the rotating block 50806 continues to rotate, multiple toggle blocks 50807 sequentially toggle the synchronization block 50804, thereby achieving continuous and intermittent striking of the filter screen 506, ensuring that the filter screen 506 remains unobstructed throughout the drainage process.

[0043] Furthermore, the scraping mechanism 10 is disposed on the sorting tank 2 and is used to scrape impurities floating on the water surface to the impurity discharge slide 7.
[0044] In this embodiment, after the water supply is stopped, floating impurities still float on the water surface, at which point the scraping mechanism 10 is required.
