[0031] The device adopts the above structure for cooperation, can filter tea oil, get pure tea oil, specific operation is, through in the tea oil enters the inside of the collecting tank 311, will pass through the filter plate 31 and filter the dregs in the tea oil on the upper surface of the filter plate 31, this is the first filtration, after the first filtration, the tea oil can be heated, remove n-hexane in tea oil, then the tea oil can be collected, in the process of collection, the tea oil is transported to the inside of the liquid collecting bin 331, the device transports the tea oil to the inside of the liquid collecting bin 331, from bottom to top, in the process of transportation, will pass through the filter screen 33, the filter screen 33 can filter out the tiny dregs in the tea oil, this is the second filtration, through twice filtration, can get pure tea oil, in order to continue to process tea oil in subsequent operation.

[0032] In a preferred embodiment, the inside of the extraction tank 1 is slidably installed with a baffle 4, a sliding groove 5 is formed in the inner wall of the extraction tank 1, a moving block 6 is slidably connected in the inside of the sliding groove 5, a spring 7 is fixedly connected to one side of the moving block 6, the other end of the spring 7 is fixedly connected to the inner wall of the sliding groove 5, and the baffle 4 is fixedly connected to one side of the moving block 6. The device removes n-hexane in tea oil by heating tea oil, but the steam generated after n-hexane is heated has certain harm, in order to prevent the steam from polluting the atmosphere, the device uses the baffle 4 to limit the position of the steam, which is convenient for collecting and treating the steam.

[0033] In a preferred embodiment, the top of the support frame 2 is fixedly connected with a gas cylinder 8, the telescopic end of the gas cylinder 8 is rotatably connected with a transmission rod 9, one end of the transmission rod 9 is fixedly connected with a pressing plate 10, a plurality of through holes 11 are formed in the upper surface of the pressing plate 10 and are evenly arranged on the upper surface of the pressing plate 10. After the raw materials are crushed, they are added into the U-shaped bin 12. Since the crushed raw materials are very light, they will float in the organic solvent, and the efficiency of thorough mixing will be slow. Therefore, the device uses the gas cylinder 8 to control the movement of the pressing plate 10, so that the raw materials are all pressed in the organic solvent, thereby accelerating the mixing of the raw materials and the organic solvent to form tea oil.

[0034] In a preferred embodiment, the inside of the extraction tank 1 is fixedly connected with a U-shaped bin 12, the bottom of the U-shaped bin 12 is fixedly connected with a discharge pipe 13, the outer surface of the discharge pipe 13 is provided with an electric control valve 14, the rotating shaft of the electric control valve 14 is fixedly connected with a disc 15, the outer side of the disc 15 is fixedly connected with a protrusion 16, and the protrusion 16 corresponds to the position of the baffle 4. In order to conveniently control the lifting of the filter plate 31 in the collecting tank 311, the disc 15 is installed outside the electric control valve 14, and the protrusion 16 is installed on the side of the disc 15. Through the rotation of the disc 15, the protrusion 16 can be rotated, so that the baffle 4 can be controlled to move through the protrusion 16, thereby driving the filter plate 31 to move up and down in the collecting tank 311, meeting the use.

[0035] The device uses organic solvent and raw materials to produce tea oil, and after the production of tea oil, the inside is still mixed with organic solvent. In order to ensure the purity of the tea oil, the electric heating plate 17 is fixedly connected at the bottom of the collecting tank 311, the electric heating plate 17 is electrically connected with the PLC controller 18, the PLC controller 18 is electrically connected with the temperature sensor 19, and the temperature sensor 19 is fixedly installed at the bottom of the extraction tank 1. Because the organic solvent has strong volatility, the organic solvent is volatilized by heating the collecting tank 311, so as to remove the organic solvent in the tea oil and obtain pure tea oil.

[0036] After removing the organic solvent in the tea oil, the tea oil needs to be transferred to the inside of the liquid collecting bin 331. In order to facilitate the transfer of the tea oil, the liquid pumping machine 20 is fixedly connected to the outer surface of the extraction tank 1. The inlet end of the liquid pumping machine 20 is fixedly connected with the water inlet pipe 21, and the water inlet pipe 21 is in communication with the inside of the collecting tank 311. The outlet end of the liquid pumping machine 20 is fixedly connected with the connecting pipe. The tea oil in the collecting tank 311 is pumped out by the liquid pumping machine 20 and transported into the inside of the liquid collecting bin 331, which is convenient for collecting the tea oil.

[0037] The steam generated after n-hexane is heated will pollute the atmosphere, so the waste gas treatment mechanism 22 is arranged on the hollow cylinder 321. The waste gas treatment mechanism 22 includes a refrigerator 221, a temperature detector 222 and an air inlet pipe 223. The refrigerator 221 is fixedly installed at the top of the hollow cylinder 321. The temperature detector 222 is fixedly installed outside the hollow cylinder 321, and the detection end is arranged in the inside of the hollow cylinder 321. One end of the air inlet pipe 223 is in communication with the inside of the hollow cylinder 321, and the other end is in communication with the inside of the extraction tank 1. The bottom of the baffle plate 4 is fixedly connected with the connecting rod 23. One end of the connecting rod 23 is fixedly connected with the upper surface of the filter plate 31. The connecting rod 23 is provided with two and is evenly arranged on the upper surface of the filter plate 31. In actual use, the steam in the extraction tank 1 is transported into the inside of the hollow cylinder 321, and the temperature in the inside of the hollow cylinder 321 is lowered in advance, so as to change the steam into liquid. Finally, the liquid is discharged from the inside of the hollow cylinder 321, which effectively prevents the steam from polluting the atmosphere and meets the use.

[0038] The device is provided with a filter plate 31 in the collecting tank 311, which filters out the crushed material. In order to facilitate the removal of the crushed material on the filter plate 31, the cleaning pipe 32 is arranged to blow the crushed material away. A plurality of slag discharge holes 24 are arranged on the bottom of the extraction tank 1, which can make the crushed material falling into the bottom of the extraction tank 1 fall from the position of the slag discharge hole 24, so as to keep the inside of the extraction tank 1 clean and facilitate the continuous use in the later period.

[0039] Specifically, the working process or working principle of the camellia oil extraction device is as follows: the current extraction steps of camellia oil are cleaning, drying and crushing camellia seeds, then putting the crushed camellia seeds into an extraction tank 1, and putting n-hexane in the tank, through the mixing of the two, camellia oil can be obtained, then separation and filtration are carried out to obtain pure camellia oil.

[0040] However, for the filtration operation, the separated camellia oil is filtered by a filter screen 33. Since the raw material is camellia seed residue, it is difficult to completely filter the camellia seed residue by general filtration, so multiple filtration is required to obtain pure camellia oil, which wastes time, increases the process and increases the production cost. Therefore, the device is designed to solve the problem. The specific operation is as follows: connect the external power supply. The device directly operates on the crushed raw material. Therefore, the crushed camellia seeds are added to the inside of the collection tank 311 through the top of the extraction tank 1, and an organic solvent such as n-hexane is added to the inside of the U-shaped bin 12 in advance. The organic solvent is mixed with the raw material. After the raw material is added to the organic solvent, the air cylinder 8 is opened, the telescopic end of the air cylinder 8 is extended, and the pressing plate 10 is driven to extend into the inside of the U-shaped bin 12. Since the upper surface of the pressing plate 10 is provided with a plurality of through holes 11, the pressing plate 10 can be completely immersed in the liquid, and the raw material can be completely immersed in the liquid.

[0041] After a period of immersion, the tea oil component in the raw material can be dissolved out to form tea oil in the liquid. The device is provided with an electric control valve 14 on the discharge pipe 13 at the bottom position of the U-shaped bin 12, which is electrically connected with the PLC controller 18 and can automatically control the operation of the electric control valve 14. The discharge pipe 13 is opened, and the liquid in the U-shaped bin 12 will flow into the inside of the collection tank 311. When the electric control valve 14 is working, the disc 15 will be driven to rotate, thereby driving the protruding block 16 to rotate. When the protruding block 16 is downward, the discharge pipe 13 is in an open state, and at this time the baffle 4 will move downward under the extrusion of the protruding block 16, and drive the filter plate 31 to move downward in the inside of the collection tank 311, to prevent the liquid from splashing out of the filter plate 31.

[0042] By setting the filter plate 31 which can slide up and down in the inside of the collection tank 311, the crushed material in the liquid can be filtered, preventing a large amount of crushed material from mixing with the tea oil in the inside of the collection tank 311. After the liquid in the U-shaped bin 12 is discharged, the electric control valve 14 is controlled to close the discharge pipe 13. At this time, the baffle 4 will move upward under the action of the spring 7, and drive the filter plate 31 to move upward in the inside of the collection tank 311.

[0043] Since the shielding plate 4 drives the filter plate 31 to move downward before, the filter plate 31 will be soaked in the liquid inside the collecting tank 311, when the shielding plate 4 moves upward, drives the filter plate 31 to move upward, lifts the debris on the filter plate 31 out of the liquid, separates the debris from the liquid, realizes the effect of removing slag from the liquid, in order to remove n-hexane in the liquid, so after the liquid completely enters the inside of the collecting tank 311, the electric heating plate 17 can be opened, and the collecting tank 311 is heated by the electric heating plate 17. Since n-hexane is volatile, the volatilization effect is more obvious after being heated, so through heating, n-hexane in the liquid can be removed, and by controlling the heating temperature, the steam generated by tea oil itself can be greatly reduced. The steam is concentrated at the bottom end inside the extraction tank 1 by the shielding of the shielding plate 4.

[0044] In order to facilitate the treatment of waste gas and prevent pollution control, when extracting tea oil, the refrigeration machine 221 is first opened, and the temperature inside the hollow cylinder 321 is lowered by the refrigeration machine 221. At this time, the air pressure inside the hollow cylinder 321 is also low, so that the air pressure difference is formed with the inside of the extraction tank 1, and the generated steam is automatically sucked into the inside of the hollow cylinder 321. The waste gas can be collected and treated, and the waste gas entering the inside of the hollow cylinder 321 will not immediately become liquid, so the air suction machine 322 can be opened at this time. The air suction machine 322 sucks the gas in the hollow cylinder 321 and discharges it through the cleaning pipe 32. The gas blown out of the cleaning pipe 32 will directly blow the upper surface of the filter plate 31, blow off all the debris on the upper surface of the filter plate 31, and fall to the bottom of the extraction tank 1. The debris is discharged from the extraction tank 1 through the slag discharge hole 24.

[0045] If the gas in the hollow cylinder 321 is not needed, the air suction machine 322 is closed. At this time, the gas in the hollow cylinder 321 will gradually form liquid at low temperature, and then it can be discharged, effectively preventing pollution of the atmosphere.

[0046] At this time, the liquid in the collecting tank 311 is tea oil left after separation, and then the liquid suction machine 20 is opened. The tea oil in the collecting tank 311 is transferred to the inside of the liquid collecting bin 331 by the liquid suction machine 20. The liquid suction machine 20 transports the tea oil to the bottom of the liquid collecting bin 331. As the tea oil in the liquid collecting bin 331 increases, the filter screen 33 will be soaked in the tea oil. As the tea oil increases, the liquid level in the liquid collecting bin 331 will also rise. At this time, the tea leaves can be further filtered by the filter screen 33 to filter out small debris and leave it in the liquid collecting bin 331, so as to obtain pure tea oil. Then the tea oil is transferred to the subsequent process for processing, and the tea oil containing debris at the bottom of the liquid collecting bin 331 is cleaned out.

[0047] After the operation is completed, the power supply needs to be turned off, and the device is cleaned and dried for later use.

[0048] It should be noted that the air suction machine 322, the cylinder 8, the electric control valve 14, the PLC controller 18, the temperature sensor 19, the refrigerating machine 221 and the temperature detector 222 are devices or equipment existing in the prior art or devices or equipment that can be realized in the prior art, and their power supply, specific components and principles are clear to those skilled in the art, and thus will not be described in detail.
