Description

Technical Field

[0001] This invention relates to the field of sesame raw material processing technology, and in particular to an integrated multi-stage air separation and magnetic separation device for sesame raw materials used in sesame oil production. Background Technology

[0002] Sesame oil is an edible oil extracted from sesame seeds. In industrial production, after the sesame raw materials enter the factory, they first undergo a pre-treatment process, which involves screening, air separation, gravity separation, and magnetic separation to clean the material and remove foreign matter such as straw debris, stones, and iron impurities. After cleaning, the sesame seeds can be washed and conditioned according to the process route. Subsequently, oil can be extracted using either the water displacement method or the pressing method. The water displacement method requires roasting the seeds, cooling the smoke, grinding into a paste, mixing the paste and oil, and separating the oil and water to obtain crude oil. The pressing method involves roasting the processed sesame seeds and then directly pressing them mechanically to obtain crude oil. The crude oil then undergoes sedimentation and filtration processes to obtain the finished sesame oil. The entire processing flow is carried out in accordance with the oil production standards.

[0003] A sesame cleaning machine, disclosed in CN204933757U, includes a raw material silo, a discharge device, an air separator, a screening machine, a destoner, and a magnetic funnel connected in sequence. Each of the discharge device, air separator, and destoner is connected to a cyclone separator, and each cyclone separator has an impurity outlet at its bottom. The air separator includes at least two air separation chambers; one air separation chamber has a sesame outlet connected to the screening machine at its bottom, and the other air separation chambers have impurity outlets at their bottoms. Sesame seeds are lifted from the raw material silo by a pneumatic elevator to the discharge device, and then enter the air separator, where impurities with a specific gravity lower than sesame seeds, such as sesame husks and straw fragments, are separated according to their specific gravity. The sesame seeds then enter the screening machine, where larger impurities are separated according to their size. Next, the sesame seeds enter the destoner, where larger impurities, such as pebbles, are separated according to their specific gravity. Finally, the sesame seeds enter the magnetic funnel, where magnetic sand and gravel are separated, resulting in relatively pure sesame seeds.

[0004] There are still some problems when processing sesame seeds.

[0005] In the sesame raw material cleaning process, air separators are often used to separate lighter impurities such as stems, leaves, and shriveled husks, followed by magnetic separators to remove small metal particles such as iron filings and iron powder mixed in with the material. Currently, sesame seeds are often laid flat on a screen surface, and impurities are removed by blowing air through a fan. In this method, the airflow from the fan directly acts on the sesame material on the screen. The airflow intensity needs to balance the removal of light impurities with the retention of sesame seeds, making parameter adjustment difficult. If the fan volume is increased to ensure effective impurity removal, some lighter, intact sesame seeds are easily blown off the screen along with the impurities, resulting in raw material loss and waste of resources, which is detrimental to improving raw material utilization. Summary of the Invention

[0006] The purpose of this application is to provide a multi-stage air separation and magnetic separation integrated device for sesame raw materials used in sesame oil production. The device enables sesame seeds inside the collection hopper to enter the screen plate. The rotation of the fan shaft generates airflow, which blows the lighter impurities of stems and leaves in the sesame seeds on the screen plate into the collection box for centralized collection. Then, the sesame seeds enter the box through the receiving plate for magnetic separation.

[0007] To achieve the above objectives, this application provides the following technical solution: a multi-stage air-separation and magnetic separation integrated device for sesame raw materials used in sesame oil production, comprising a base, a housing fixedly installed on the base, a door provided at the bottom of the housing, a pair of supports fixedly connected to the top surface of the base, and a collection hopper fixedly installed at the top of the pair of supports; an air-separation component disposed at the bottom of the collection hopper for separating impurities in the raw materials inside the collection hopper; and a magnetic separation component disposed inside the housing for adsorbing and separating magnetic substances from the raw materials.

[0008] Preferably, the air separator assembly includes a docking plate, a receiving plate, a limiting plate, a wind hood, and a wind blade shaft; one end of the docking plate is fixedly connected to a bracket, the other end of the docking plate is fixedly connected to the receiving plate, the limiting plates are fixed on both sides of the receiving plate, a wind hood is installed between the limiting plates, and a wind blade shaft is rotatably connected inside the wind hood.

[0009] Preferably, a support plate is fixedly connected to the bracket, one end of the support plate is fixedly connected to a docking column, the docking column is fixedly connected to a collection box, a sieve plate is installed on the collection box by bolts, and a vibration motor is installed on both sides of the sieve plate.

[0010] Preferably, the magnetic separator includes a magnetic cylinder, a rotating shaft, a first pulley, a first transmission belt, a second pulley, a drive rod, and a drive motor; the magnetic cylinder is disposed inside the housing, a rotating shaft is fixedly connected to one side of the magnetic cylinder, one end of the rotating shaft extends outside the housing, a first pulley is fixedly connected to one end of the rotating shaft, a first transmission belt is sleeved on the first pulley, and the other end of the first transmission belt is sleeved on the second pulley.

[0011] Preferably, the second pulley is fixedly connected to one end of the drive rod, the other end of the drive rod is fixedly connected to the output end of the drive motor, and the drive motor is fixedly mounted on the base.

[0012] Preferably, a third pulley is fixedly connected to the rotating shaft, a second transmission belt is sleeved on the third pulley, the other end of the second transmission belt is sleeved on a fourth pulley, and the fourth pulley is fixedly connected to one end of the fan blade shaft.

[0013] Preferably, a positioning rod is fixedly connected to the inner wall of the housing, one end of the positioning rod extends into the interior of the magnetic cylinder, the other side of the magnetic cylinder is rotatably connected to the positioning rod, and an electromagnet is fixedly installed on the positioning rod.

[0014] Preferably, a discharge hopper is installed on one side of the box, and a receiving box is installed on the other side of the box.

[0015] In summary, the present invention has the following beneficial effects:

[0016] This device uses an inclined screen plate and a vibrating motor to continuously vibrate the sesame seeds falling onto the screen plate. This effectively breaks up clumps of sesame seeds, prevents material buildup and blockage, and ensures that the sesame seeds can be smoothly conveyed downwards along the screen plate. At the same time, the rotating fan shaft inside the fan hood generates airflow, which blows lighter impurities such as shriveled shells and debris from the sesame seeds into the collection box. This achieves air separation of sesame seeds from light impurities, completing the initial impurity removal process in advance and improving the cleanliness of the materials to be processed later.

[0017] 2. A semi-circular electromagnet is used in conjunction with a rotating magnetic cylinder for metal impurity removal. The magnetic cylinder rotates continuously with the shaft, and under the action of the electromagnet's magnetic force, it can efficiently adsorb metal impurities such as iron filings mixed in the sesame raw materials. When the magnetic cylinder rotates to the discharge hopper position, there is no magnetic force from the electromagnet in this area, and the metal impurities adsorbed on the outer wall of the magnetic cylinder automatically fall off into the discharge hopper, completing the automatic separation of metal impurities. There is no need for manual cleaning of impurities on the surface of the magnetic cylinder. The impurity removal operation is continuous and stable, effectively preventing metal impurities from being mixed into the finished sesame product and ensuring processing safety.

[0018] 3. The equipment integrates vibrating screening, air separation and magnetic separation for impurity removal. Sesame seeds are first fed into the hopper and the vibrating screen removes light impurities. Then, they enter the box to complete the adsorption and separation of metal impurities. The two impurity removal processes are connected continuously, and the material flow does not require manual transfer, which simplifies the processing flow, improves the overall impurity removal efficiency of sesame seeds, reduces manual operation, and is suitable for large-scale sesame processing.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example: Reference Figure 1 - Figure 8The device shown is an integrated multi-stage air-separation and magnetic separation device for sesame raw materials used in sesame oil production. It includes a base 100, a housing 101 fixedly installed on the base 100, a door 102 at the bottom of the housing 101, a pair of supports 103 fixedly connected to the top surface of the base 100, and a collection hopper 104 fixedly installed at the top of the pair of supports 103; an air separation component 200, which is located at the bottom of the collection hopper 104 and is used to separate impurities in the raw materials inside the collection hopper 104; and a magnetic separation component 300, which is located inside the housing 101 and is used to adsorb and separate magnetic substances from the raw materials.

[0031] Specifically, it should be noted that the vibration motor 210 and the drive motor 307 are electrically connected to the control unit via wires. The specific working principles between them are based on existing technology and will not be elaborated on here. The wind speed generated by the rotation of the fan shaft 205 is controlled at 2.5-3.5 m / s to prevent the sesame seeds from being blown away. The positioning rod 311 is hollow inside and is used to insert wires to power the electromagnet 312.

[0032] As one embodiment of this invention, the air separation component 200 includes a docking plate 201, a receiving plate 202, a limiting plate 203, an air hood 204, and a fan shaft 205. One end of the docking plate 201 is fixedly connected to the bracket 103, and the other end of the docking plate 201 is fixedly connected to the receiving plate 202. Limiting plates 203 are fixed on both sides of the receiving plate 202. An air hood 204 is installed between the limiting plates 203. The fan shaft 205 is rotatably connected inside the air hood 204. A support plate 206 is fixedly connected to the bracket 103. One end of the support plate 206 is fixedly connected to a docking column 207. The docking column 207 is fixedly connected to a collection box 208. A sieve plate 209 is installed on the collection box 208 by bolts. Vibration motors 210 are installed on both sides of the sieve plate 209.

[0033] Specifically, sesame seeds are added to the inside of the collecting hopper 104, and then the sesame seeds enter the sieve plate 209 through the bottom opening of the collecting hopper 104. The sieve plate 209 is inclined, and a limiting plate 203 is fixedly connected to the receiving plate 202. A wind hood 204 is fixedly installed on the limiting plate 203. A fan shaft 205 is rotatably connected inside the wind hood 204. The rotation of the fan shaft 205 generates airflow, which blows air onto the sieve plate 209. Because the sieve plate 209 is inclined, and the two sides of the sieve plate 209... A vibration motor 210 is installed on the side. The operation of the vibration motor 210 causes the sieve plate 209 to vibrate, preventing sesame seeds from piling up. Then, the airflow blows the lighter impurities in the sesame seeds into the collection box 208, while the heavier sesame seeds enter the receiving box 314 through the lower side of the receiving plate 202. The bottom of the receiving box 314 is inclined, and the receiving box 314 is connected to the box body 101. The sesame seeds inside the receiving box 314 will enter the box body 101 for further processing.

[0034] In one embodiment of this invention, the magnetic separator 300 includes a magnetic cylinder 301, a rotating shaft 302, a first pulley 303, a first transmission belt 304, a second pulley 305, a drive rod 306, and a drive motor 307. The magnetic cylinder 301 is disposed inside the housing 101. The rotating shaft 302 is fixedly connected to one side of the magnetic cylinder 301. One end of the rotating shaft 302 extends outside the housing 101, and the first pulley 303 is fixedly connected to one end of the rotating shaft 302. The first transmission belt 304 is sleeved on the first pulley 303, and the other end of the first transmission belt 304 is sleeved on the second pulley 305. The second pulley 305 is fixedly connected to one end of the drive rod 306, and the other end of the drive rod 306 is connected to the drive motor 307. The output end of 07 is fixedly connected, the drive motor 307 is fixedly installed on the base 100, the third pulley 308 is fixedly connected to the rotating shaft 302, the second transmission belt 309 is sleeved on the third pulley 308, the other end of the second transmission belt 309 is sleeved on the fourth pulley 310, the fourth pulley 310 is fixedly connected to one end of the fan blade shaft 205, the positioning rod 311 is fixedly connected to the inner wall of the housing 101, one end of the positioning rod 311 extends into the interior of the magnetic cylinder 301, the other side of the magnetic cylinder 301 is rotatably connected to the positioning rod 311, the electromagnet 312 is fixedly installed on the positioning rod 311, the discharge hopper 313 is installed on one side of the housing 101, and the receiving box 314 is installed on the other side of the housing 101.

[0035] Specifically, when sesame seeds enter the box 101, the drive motor 307 operates to rotate the second pulley 305 on the drive rod 306. The rotation of the second pulley 305 drives the first pulley 303 to rotate through the first transmission belt 304, thereby facilitating the rotation of the shaft 302 to drive the magnetic cylinder 301 to rotate. The electromagnet 312 is set to half a turn, so that the bottom of the box 101 and the side near the discharge hopper 313 are magnetic areas. The electromagnet 312 generates magnetic force to attract metal objects in the sesame seeds to the outer surface of the magnetic cylinder 301. Then, when the magnetic cylinder 301 continues to rotate to the position of the discharge hopper 313, the metal impurities on the surface of the magnetic cylinder 301 will fall into the discharge hopper 313 and be separated.

[0036] To further explain, a rotating shaft 302 is fixedly connected to one side of the magnetic cylinder 301, and the other side of the magnetic cylinder 301 is rotatably connected to the positioning rod 311. One end of the positioning rod 311 is fixedly connected to the housing 101, and the other end of the positioning rod 311 extends into the magnetic cylinder 301 without contacting the inner wall of the magnetic cylinder 301, and is used to install the electromagnet 312.

[0037] The working principle of this invention is as follows: Sesame seeds are added to the inside of the collecting hopper 104, and then the sesame seeds enter the sieve plate 209 through the bottom opening of the collecting hopper 104. The sieve plate 209 is inclined, and a limiting plate 203 is fixedly connected to the receiving plate 202. A wind hood 204 is fixedly installed on the limiting plate 203. A fan shaft 205 is rotatably connected inside the fan hood 204. The rotation of the fan shaft 205 generates airflow, which blows air onto the sieve plate 209. Since the sieve plate 209 is inclined, and vibration motors 210 are installed on both sides of the sieve plate 209, the operation of the vibration motors 210 causes the sieve plate 209 to vibrate, preventing the sesame seeds from piling up. Then, the airflow blows the lighter impurities in the sesame seeds into the inside of the collecting box 208, while the heavier sesame seeds enter the box 101 through the receiving plate 202 for further processing.

[0038] When sesame seeds enter the box 101, the drive motor 307 operates, causing the second pulley 305 on the drive rod 306 to rotate. The rotation of the second pulley 305 drives the first pulley 303 to rotate through the first transmission belt 304, thereby facilitating the rotation of the shaft 302 to drive the magnetic cylinder 301 to rotate. The electromagnet 312 is set to half a turn. The electromagnet 312 generates magnetic force to attract metal objects in the sesame seeds to the outer surface of the magnetic cylinder 301. Then, when the magnetic cylinder 301 continues to rotate to the discharge hopper 313, the metal impurities on the surface of the magnetic cylinder 301 will fall into the discharge hopper 313 and be separated because there is no magnetic force from the electromagnet 312.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
