Description

Technical Field

[0001] This utility model belongs to the field of milk thistle separation technology, and specifically relates to a milk thistle separation device. Background Technology

[0002] Milk thistle is a herb, and milk thistle seed oil is extracted from the milk thistle seeds, which are used for both medicinal and edible purposes. The production of milk thistle seed oil requires separating the shell and kernel of the milk thistle seeds and then pressing the kernels.

[0003] Existing traditional separation methods are not conducive to separating milk thistle seed shells and kernels, which easily leads to a lot of kernels sticking to the shells, resulting in waste of milk thistle seed kernels. At the same time, they cannot effectively separate shells, whole seeds and damaged seeds, thus affecting the economic benefits of the product and having certain limitations. Summary of the Invention

[0004] This utility model provides a milk thistle separation device, which aims to solve the problems of existing traditional separation methods that are not conducive to separating milk thistle seed shells and kernels, easily causing a lot of kernels to stick to the shells and resulting in waste of milk thistle seed kernels. At the same time, it is not possible to sort shells, whole seeds and damaged seeds well, thus affecting the economic benefits of the product and having certain limitations.

[0005] This utility model provides a milk thistle separation device, including a separation cylinder, an inlet pipe connected to the upper side of the separation cylinder, an outlet pipe connected to the upper middle part of the separation cylinder, a separation groove integrally formed on the periphery of the separation cylinder, a first outlet provided at the lower end of the separation cylinder, a plurality of nozzle groups provided on the inner wall surface of the separation cylinder, and a flow guide provided on the inner wall of the separation cylinder.

[0006] Furthermore, the feed pipe enters along the tangential direction of the separator cylinder.

[0007] By adopting the above technical solution, the material rotates tightly against the inner wall of the separation cylinder under the action of centrifugal force, forming a stable vortex layer. This design utilizes density differences to achieve initial separation: the heavier milk thistle kernels are thrown to the outside due to centrifugal force, while the lighter shells, debris, etc. gather towards the center, providing a basis for subsequent grading and solving the problem of shell and kernel mixing in traditional separation.

[0008] Furthermore, the separation groove is arranged around the outer wall of the separation cylinder, the interior of the separation groove is connected to the interior of the separation cylinder, the bottom of the separation groove is inclined, and the bottom of the separation groove is provided with multiple second discharge ports, each of which is equipped with an electrically controlled valve.

[0009] By adopting the above technical solution, the separation tank serves as a graded collection channel. Its inclined structure guides the broken kernels to gather at a lower level. By controlling the opening and closing of the electronically controlled valve, the discharge of half-kernel broken kernels (medium quality) can be achieved, which significantly improves resource utilization and reduces the waste of half-kernel broken kernels.

[0010] Furthermore, the nozzle assembly includes an upper nozzle fixed to the upper side of the separation tank and a lower nozzle fixed to the lower side of the separation tank. The upper nozzle is tilted downward at 15° and the lower nozzle is tilted upward at 10°.

[0011] By adopting the above technical solution, the upper nozzle can generate a downward airflow, preventing the light shells from entering the separation tank under the action of the airflow. At the same time, the heavy whole kernels will continue to move downward under the action of centrifugal force until they are discharged from the first discharge port. The lower nozzle can generate an upward airflow, so the medium-quality half-kernels and broken kernels will be lifted into the separation tank by the upward airflow. The light shells will be lifted upward and discharged from the discharge pipe under the action of airflow and negative pressure adsorption. The heavy whole kernels will still be discharged from the first discharge port under the action of their own weight and centrifugal force.

[0012] Furthermore, the upper and lower nozzles are staggered in the vertical direction.

[0013] By adopting the above technical solution, the staggered layout eliminates the spray blind zone of the nozzle group, covers the entire cross-section of the separation cylinder, enhances the penetration of the material layer, and improves the separation efficiency.

[0014] Furthermore, the flow guide is located on the upper side of the upper nozzle, and the flow guide includes a beveled part and an arc-shaped part, which are integrally formed and the beveled part is located on the upper side of the arc-shaped part.

[0015] By adopting the above technical solution, the heavy whole kernels thrown out by centrifugal force are guided to slide down the wall to the first discharge port, avoiding the kernels from entering the separation tank through the central light zone, reducing the risk of shell and kernel mixing from the source. The arc surface can guide the flow direction of the upward airflow, avoiding collision with the main airflow from the feed pipe, thus generating turbulence and improving the overall separation efficiency.

[0016] Furthermore, the bottom of the discharge pipe is located between the guide section and the feed pipe, and the bottom of the discharge pipe is tapered, narrower at the top and wider at the bottom.

[0017] By adopting the above technical solution, the lightweight shell can be adsorbed and discharged from the bottom of the discharge pipe under the action of the central negative pressure zone, and the flared cone shape of the discharge pipe can improve the discharge efficiency.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through the setting of the separation tank and the nozzle assembly, allows the upper and lower nozzles to form an air curtain when screening materials, thereby preventing light shells from entering the separation tank. At the same time, it can screen medium-quality half-kernel fragments, allowing them to enter the separation tank under the action of centrifugal force and airflow, thus achieving the separation of light shells, medium-quality half-kernel fragments, and heavy-quality whole kernels.

[0020] 2. This utility model, through the setting of the flow guide, guides the heavy whole kernels thrown out by centrifugal force to slide down the wall to the first discharge port, avoiding the kernels from entering the separation tank through the central light zone, reducing the risk of shell and kernel mixing from the source. The arc surface can guide the flow direction of the upward airflow, avoiding collision with the main airflow from the feed pipe, thereby generating turbulence and improving the overall separation efficiency.

The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1-3 This utility model provides a milk thistle separation device, including a separation cylinder 1. The upper side of the separation cylinder 1 is connected to a feed pipe 2. The feed pipe 2 enters along the tangential direction of the separation cylinder 1. Under the action of centrifugal force, the material rotates tightly against the inner wall of the separation cylinder 1, forming a stable vortex layer. The initial separation is achieved by utilizing the density difference. The heavier milk thistle kernels are thrown to the outside due to centrifugal force, while the lighter shells, debris, etc. gather towards the center, providing a basis for subsequent grading and solving the problem of shell and kernel mixing in traditional separation.

[0029] Reference Figures 1-3 The upper middle part of the separating cylinder 1 is connected to the discharge pipe 3. The bottom of the discharge pipe 3 is located between the guide section 7 and the feed pipe 2. The bottom of the discharge pipe 3 is tapered, narrow at the top and wide at the bottom. The lightweight shell can be drawn upward and discharged from the bottom of the discharge pipe 3 under the action of the central negative pressure zone. The flared tapered shape of the discharge pipe 3 can improve the discharge efficiency. The separating cylinder 1 is integrally formed with a separating groove 4 around its periphery. The separating groove 4 is arranged around the outer wall of the separating cylinder 1. The interior of the separating groove 4 is connected to the interior of the separating cylinder 1. The bottom of the separating groove 4 is inclined. The bottom of the separating groove 4 is provided with multiple second discharge ports 41. The second discharge ports 41 are equipped with electric control valves. The separating groove 4 serves as a graded collection channel. Its inclined bottom structure guides the broken seeds to gather at a lower position. By controlling the opening and closing of the electric control valve, which is connected to an external power supply and controlled by an external controller, the medium quality of half-kernel broken seeds can be discharged, which significantly improves resource utilization and reduces the waste of half-kernel broken seeds.

[0030] Reference Figures 1-3The lower end of the separator 1 is provided with a first discharge port 5. The inner wall of the separator 1 is provided with several nozzle assemblies 6. Each nozzle assembly 6 includes an upper nozzle 61 fixed to the upper side of the separator 4 and a lower nozzle 62 fixed to the lower side of the separator 4. The upper nozzle 61 is inclined downwards at 15°, and the lower nozzle 62 is inclined upwards at 10°. The upper nozzle 61 and lower nozzle 62 are staggered in the vertical direction. The upper nozzle 61 is installed at full-point positions on the inner wall of the separator 1, such as 0° and 30°, while the lower nozzle 62 is installed at half-point positions on the inner wall of the separator 1, such as 15° and 45°. This staggered layout eliminates the blind spots of the nozzle assembly 6, covering the entire area. The cross-section of the separation cylinder 1 enhances the penetration of the material layer and improves the separation efficiency. The upper nozzle 61 can generate a downward airflow to prevent light shells from entering the separation tank 4 under the action of the airflow. At the same time, the heavy whole kernels will continue to move downward under the action of centrifugal force until they are discharged from the first discharge port 5. The lower nozzle 62 can generate an upward airflow, so the medium-quality half-kernel fragments will be lifted into the separation tank 4 by the upward airflow. The light shells will be lifted upward and discharged from the discharge pipe 3 under the action of the airflow and the negative pressure adsorption. The heavy whole kernels will still be discharged from the first discharge port 5 under the action of their own weight and centrifugal force.

[0031] Reference Figures 1-3 The inner wall of the separation cylinder 1 is provided with a flow guide 7, which is located on the upper side of the upper nozzle 61. The flow guide 7 includes an inclined surface 71 and an arc surface 72. The inclined surface 71 and the arc surface 72 are integrally formed, and the inclined surface 71 is located on the upper side of the arc surface 72. It guides the heavy whole kernels thrown out by centrifugal force to slide down the wall to the first discharge port 5, avoiding the kernels from entering the separation tank 4 through the central light area, thus reducing the risk of shell and kernel mixing from the source. The arc surface 72 can guide the flow direction of the upward airflow, avoiding collision with the main airflow from the feed pipe 2, thereby generating turbulence and improving the overall separation efficiency.

[0032] The specific implementation method is as follows: When in use, the processed material will rotate and descend along the inner wall of the separation cylinder 1 from the feed pipe 2, generating centrifugal force. The heavy whole kernels will continue to descend under their own weight and the action of the upper nozzle 61 until they are discharged from the first discharge port 5. At the same time, the airflow of the upper nozzle 61 and the lower nozzle 62 will cause the medium half kernels to overcome the centrifugal force and enter the separation tank 4 until the electric control valve in the separation tank 4 opens and is discharged from the second discharge port 41. The light shell will move upward under the airflow of the lower nozzle 62 and the negative pressure adsorption of the central area and be discharged from the discharge pipe 3. The whole process realizes that the light shells, medium half kernels, and heavy whole kernels are discharged from different discharge ports, avoiding the waste of kernels and reducing limitations.
