Description

Technical Field

[0001] The present invention relates to a separation device, and in particular to a device for wet-separating flaxseed hulls and flaxseed kernels. Background Art

[0002] Flax (Linum usitatissimum L.), also known as common flax, is one of the seven major oil crops in the world. The output of flaxseed in China ranks second in the world after Canada. Flaxseed contains various valuable components, such as flaxseed gum, lignans, flaxseed oil, flax cyclopeptides, flax protein, etc. Flaxseed gum and lignans mainly exist in flaxseed hulls, while flaxseed oil, flax cyclopeptides, and flax protein mainly exist in flaxseed kernels. Directly extracting flaxseed gum and lignans from unpeeled flaxseed results in a low extraction rate of flaxseed gum and lignans due to the intact flaxseed hulls, and there is still a high residue, which also affects the extraction rate of flax protein and flax cyclopeptides in flaxseed kernels. If the flaxseed hulls and kernels can be separated, it will reduce the mutual interference during the extraction of components from flaxseed, making it easier to extract these components from flaxseed, with a higher extraction rate, and being more conducive to the comprehensive development and utilization of flaxseed.

[0003] However, the separation of flaxseed hulls and kernels is difficult, including two problems. One problem is that it is not easy to remove the hulls from flaxseed due to the tight combination of flaxseed hulls and kernels and the high oil content in flaxseed kernels, making it difficult to separate the hulls and kernels. Another problem is that it is very difficult to separate the hull-kernel mixture after hull-kernel separation because the flaxseed hulls are relatively thick and are difficult to separate from the flaxseed kernels. With the continuous in-depth study of flaxseed, some solutions have emerged for the first problem; for the second problem, electrostatic adsorption separation equipment is currently used in practical production, but this type of equipment has high costs, large investments, high energy consumption, and limited processing capacity, greatly restricting the in-depth development and application of flaxseed; Patent CN2020103457334 provides a method for separating the hull-kernel mixture after flaxseed hull-kernel separation, but this method has high requirements for the uniformity of flaxseed hulls and flaxseed kernels, and has poor effects on non-uniform flaxseed hulls and flaxseed kernels. Therefore, in order to better comprehensively develop and utilize flaxseed, a way to solve the separation of non-uniform flaxseed hulls and flaxseed kernels is needed. Summary of the Invention

[0004] In order to solve the problems raised in the background art, the present invention provides a device for wet-separating flaxseed hulls and flaxseed kernels, which solves the problem of difficult separation of non-uniform flaxseed hulls and flaxseed kernel mixtures after flaxseed hull-kernel separation, and lays a foundation for the further comprehensive development and utilization of flaxseed.

[0005] To achieve the above object, the technical solution provided by the present invention is: a device for wet separation of flaxseed husks and flaxseed kernels, comprising: a cylinder body, cylinder ears, sprockets, a connecting shaft, a motor, a belt, a flywheel, a chain, a controller, a support plate, a separation net, a sealing ring, a piston shaft, a piston plate, an adsorption sponge, a clamping protrusion, a drain valve, characterized in that: each of the two cylinder ears has 6 sprockets (3 on each side), a chain, a support plate, and a separation net inside. The sprockets are connected by an intermediate sprocket connecting shaft. Half of the support plate close to the outside of the cylinder body is fixed to the chain. The motor is outside the cylinder ear and is connected to the sprockets inside the cylinder ear through a belt, a flywheel, and an intermediate connecting shaft. The controller is connected to the two motors, and by controlling the motors to drive the sprockets to rotate clockwise or counterclockwise, the expansion and contraction and stop of the support plate are adjusted. A separation net is placed on one side of the support plate close to the cylinder body. The holes in the middle of the separation net and the convex columns at the corresponding support plate positions are fixed horizontally through clamping protrusions. The sealing ring plays a role in preventing liquid leakage at the connecting shaft connected to the flywheel. The piston shaft can drive the piston plate to move up and down inside the cylinder body filled with water. The piston plate is at the bottom of the piston shaft. The adsorption sponge is below the piston plate, and the piston plate and the adsorption sponge are the same size horizontally. The drain valve is at the lower end outside the cylinder body and can drain the water in the cylinder body.

[0006] Further, the device for wet separation of flaxseed husks and flaxseed kernels is characterized in that: the support plate and the separation net have pores, and the pore size is 0.1 - 1.5 mm.

[0007] Further, the device for wet separation of flaxseed husks and flaxseed kernels is characterized in that: when the support plate extends into the cylinder, the separation nets on both sides can just come into contact with each other, and when the support plate contracts into the cylinder ear, the separation net can completely enter the cylinder ear.

[0008] Further, the device for wet separation of flaxseed husks and flaxseed kernels is characterized in that: the separation net can also have a spare separation net.

[0009] When the adsorption sponge adsorbs the flaxseed husks and leaves the water surface, the water surface has a certain surface tension, which will cause some of the flaxseed husks adsorbed by the adsorption sponge to fall back into the water and sink to the bottom. Therefore, the present invention designs a support plate and a separation net structure to receive the fallen flaxseed husks and intercept them again.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. By utilizing the different adsorption capabilities of the adsorption sponge for flaxseed husks and flaxseed kernels, the mixture of flaxseed husks and flaxseed kernels after flaxseed peeling can be separated, especially the non-uniform mixture of flaxseed husks and kernels can be separated, and the separation effect is good, solving the problem that it is difficult to separate the mixture of flaxseed husks and flaxseed kernels after peeling, and laying a foundation for the further comprehensive development and utilization of flaxseeds.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present invention will be specifically described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0016] Embodiment 1

[0017] As Figure 1 and Figure 2 shown, there are 6 sprockets 8 (3 on each side), chains 9, support plates 10, and separation nets 11 respectively inside the two cylinder ears 5 of the device for wet separation of flaxseed skin and flaxseed kernel mixture. The pore sizes of the support plates 10 and the separation nets 11 are 0.1 - 1.5 mm. The sprockets 8 are connected by sprocket connecting shafts 14. Half of the support plate 10 close to the outside of the cylinder block 4 is fixed to the chain 9. The motor 7 is outside the cylinder ear 5 and is connected to the sprocket 8 inside the cylinder ear 5 through a belt 12, a flywheel 13, and an intermediate connecting shaft 14. The controller 15 is connected to the two motors 7, and the expansion and contraction and stop of the support plate 10 are adjusted by controlling the motors to drive the sprockets 8 to rotate clockwise or counterclockwise. A separation net 11 is placed on one side of the support plate 10 close to the cylinder block 4. The holes in the middle of the separation net 11 and the convex columns at the corresponding positions of the support plate 10 are horizontally fixed by clamping protrusions 16. The sealing ring 6 plays a role in preventing liquid leakage at the connecting shaft 14 connected to the flywheel 13. The piston shaft 1 drives the piston plate 2 to move up and down inside the cylinder block 4 filled with water. The piston plate 2 is at the bottom of the piston shaft 1. The adsorption sponge 3 is below the piston plate 2. The piston plate 2 and the adsorption sponge 3 are the same size in the horizontal direction. The drain valve 18 is at the lower end outside the cylinder block 4 and can be used to drain the water in the cylinder block.

[0018] In the specific operation of the above embodiments: A certain amount of water is contained in the cylinder block 4, and the water level line 17 is above the cylinder lugs 5. The mixture of flaxseed husks and flaxseed kernels after the separation of flaxseed husks and kernels is at the bottom of the cylinder block 4. When the piston shaft 1 drives the piston plate 2 and the adsorption sponge 3 into the cylinder block 4 and moves downward, when the adsorption sponge 3 contacts the flaxseed husks and flaxseed kernels at the bottom of the cylinder block 4, due to the strong adsorption effect between the adsorption sponge 3 and the flaxseed husks, the flaxseed husks are preferentially adsorbed. Then, the adsorbed flaxseed husks move upward with the adsorption sponge 3 driven by the piston shaft 1. When it moves above the plane where the separation net 11 is located, the controller 15 is activated to drive the motor 7 to extend the supporting plates 10 on both sides together with the separation net 11 thereon. The two sides move towards each other until the two separation nets 11 reach the position where they contact each other. Then, the piston shaft 1 continues to move upward to completely lift the bottom adsorption sponge 3 above the water surface. After scraping off the flaxseed husks on the adsorption sponge 3, the separation net 11 is taken out, and the flaxseed husks on the separation net 11 are scraped off. The flaxseed husks in the two places are combined together, and then the separation net 11 (or the spare separation net 11) is continued to be placed back to the original position. The direction of the motor 7 is switched through the controller 15 to make the supporting plate 10 and the separation net 11 enter the cylinder lug 5 together. Then, after squeezing out the water on the adsorption sponge 3 under the piston plate 2, the piston shaft 1 is activated to move downward and continue to enter the cylinder block 4 to adsorb the flaxseed husks. The above operations are repeated until all the flaxseed husks in the cylinder block 4 are adsorbed and separated. The flaxseed kernels at the bottom are fished out with a filter screen, and then a new mixture of flaxseed husks and flaxseed kernels is added to the cylinder block 4, and the above steps are continued to be repeated until the separation is completed. If the water in the cylinder block 4 is relatively dirty during this operation process, the water inside can be drained through the drain valve 18 and replaced with new water. After the entire operation is completed, the water in the cylinder block 4 is also drained through the drain valve 18.

[0019] In addition, it should be understood that although this specific embodiment is described according to the implementation manner, not every implementation manner only contains an independent technical solution. The above description is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in the embodiments can also be appropriately combined, changed, replaced, or modified to form other implementation manners that can be understood by those skilled in the art, and still fall within the protection scope of the present invention.
