Description

Technical Field

[0002] Acer truncatum seed oil is a new resource food made from Acer truncatum seeds. Because it is rich in unsaturated fatty acids, it has gradually become popular in recent years. In the process of processing Acer truncatum seed oil, supercritical extraction technology is required.

[0003] The solvent used in supercritical extraction technology is a supercritical fluid, which is very sensitive to changes in temperature and pressure and has unique physical properties. After the extraction is completed, the supercritical extraction solvent needs to be recovered.

[0004] The recovery method in the prior art generally changes the temperature and pressure to convert the liquid solvent originally mixed with the solute into a gas state, separates it from the liquid solute, and recovers it. For example, a solvent recovery and reuse device for an oil slurry supercritical extraction system with a publication number of CN212854740U in the prior art.

[0005] However, the solvent and liquid solute have been fully mixed. In the process of converting the solvent into gas, bubbles will be generated in the solute. The bubbles move upward in the solute and are released to the liquid surface. In this process, the greater the depth of the solute, the greater the distance the bubbles move. If the solute is more viscous, the movement of the bubbles will be more difficult, which makes the solvent recovery efficiency low. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-7As shown, the utility model provides a supercritical extraction solvent recovery device for Acer truncatum seed oil, comprising a separation box 1, a controller 2 is fixedly provided on the front side of the separation box 1, a temperature regulating plate 11 is fixedly provided on the inner wall of the separation box 1, a cavity 1101 is opened inside the temperature regulating plate 11, and the top of the temperature regulating plate 11 is two symmetrical slopes;

[0031] The top of the temperature regulating plate 11 is fixedly provided with a plurality of guide protrusions 1102 that play a blocking role, thereby extending the flow path of the liquid. The inner top of the cavity 1101 is fixedly provided with a plurality of heating plates 15 and a plurality of cooling plates 16 for adjusting the temperature.

[0032] A guide tube 13 is fixedly provided on the inner wall of the separation box 1 , and a guide groove 14 is formed at the bottom end of the guide tube 13 . The guide groove 14 is located directly above the temperature regulating plate 11 .

[0033] The unseparated solute and solvent enter the guide tube 13 in a liquid state, then flow downward through the guide groove 14 and fall on the top of the temperature regulating plate 11, and disperse and flow out to both sides along the two slopes at the top of the temperature regulating plate 11. During the flow, the heating plate 15 or the cooling plate 16 adjusts the temperature of the temperature regulating plate 11, thereby causing the temperature of the solute and the solvent to change. When the temperature at which the solvent vaporizes is reached, this causes the solvent to change from liquid to gas, and the guide protrusion 1102 prolongs the time for the solvent to flow at the top of the temperature regulating plate 11, so that its temperature can be fully adjusted. When flowing at the top of the temperature regulating plate 11, the depth of the solute is shallow. After the solvent vaporizes, the distance the bubbles move is shorter, and they can be released more quickly, thereby improving the efficiency of solvent recovery.

[0034] During the operation, the cooling plate 16 cools and dissipates heat at the same time. Figure 2 , 3 As shown in , 4, and 7, a first heat dissipation pipe with a valve is fixedly provided on the rear wall of the separation box 1, and one end of the first heat dissipation pipe is communicated with the interior of the cavity 1101, so as to dissipate heat for the refrigeration plate 16 when it is working;

[0035] A feeding pipe communicating with the flow guide pipe 13 is fixedly provided at the rear side of the separation box 1 , and an infusion pump 9 is fixedly provided on the feeding pipe. The infusion pump 9 is arranged at the output end of the controller 2 to input the mixed solute and solvent into the flow guide pipe 13 .

[0036] If it is necessary to use the cooling plate 16 to cool the solvent, the cooling surface of the cooling plate 16 absorbs heat, and its heat dissipation surface dissipates the heat into the cavity 1101. At this time, the valve on the first heat dissipation tube is opened, so that the heat dissipated by the heat dissipation surface of the cooling plate 16 flows out through the first heat dissipation tube, and the infusion pump 9 transports the solute and solvent to be treated to the guide tube 13 through the feeding tube.

[0037] In the process of separating solute and solvent, it is necessary to adjust the temperature and the gas pressure at the same time, such as Figure 1 , 3 As shown in , 4 and 7, a detachable top cover 4 is provided on the top of the separation box 1, a recovery pipe 6 and a pressure regulating pipe are fixedly provided on the top of the top cover 4, and air is injected into the separation box 1 through the pressure regulating pipe to adjust the internal air pressure. An air pump 5 is fixedly provided on the recovery pipe 6, and the air pump 5 is arranged at the output end of the controller 2;

[0038] An air pressure sensor 12 is fixedly provided on the inner wall of the separation box 1 , and a temperature sensor 17 is fixedly provided on the inner wall of the cavity 1101 .

[0039] An inner box body 10 is provided at the bottom of the separation box 1. The inner box body 10 is located directly below the temperature regulating plate 11. The front side of the inner box body 10 extends to the front side of the separation box 1 and is fixed with an end plate.

[0040] A display screen 3 and a control panel 7 are fixedly provided on the front side of the separation box 1 . The control panel 7 is provided at the input end of the controller 2 , and the display screen 3 is provided at the output end of the controller 2 .

[0041] When the separation work is in progress, it is necessary to inflate or exhaust the separation box 1 through the pressure regulating pipe to adjust the air pressure inside the separation box 1 so that the air pressure inside the separation box 1 is within the range that can vaporize the solvent. At this time, the temperature and air pressure data of the separation process are collected by the temperature sensor 17 and the air pressure sensor 12 and displayed on the display screen 3 through the controller 2 for real-time monitoring. After separation by the temperature regulating plate 11, the solute still flows into the inner box 10 in the form of liquid, and the vaporized solvent is discharged from the separation box 1 under the transportation of the air pump 5 and the recovery pipe 6.

[0042] The separated solvent needs to be properly stored, such as Figure 1 , 2 As shown in , 6 and 7, a storage tank 8 is provided on one side of the separation box 1, one end of the recovery pipe 6 is fixedly connected to the top of the storage tank 8, and a partition 18 is fixedly provided on the inner wall of the storage tank 8. The partition 18 divides the interior of the storage tank 8 into a storage chamber 801 at the top and a regulating chamber 802 at the bottom, and the storage chamber 801 is used to store the recovered solvent;

[0043] An air pressure sensor 12 and a temperature sensor 17 are also fixedly provided on the inner wall of the storage chamber 801 . The air pressure sensor 12 and the temperature sensor 17 are both arranged at the input end of the controller 2 .

[0044] A heating plate 15 and a cooling plate 16 are also fixedly provided at the bottom of the partition 18.

A second heat dissipation pipe communicating with the interior of the regulating chamber 802 is fixedly provided at the rear side of the storage tank 8 to dissipate heat for the cooling plate 16 when the cooling plate 16 is working.

[0045] The vaporized solvent is transported through the recovery pipe 6 and enters the storage chamber 801. Then, the temperature and pressure inside the storage chamber 801 are adjusted by the pressure regulating pipe, the heating plate 15, and the cooling plate 16, so that the vaporized solvent is turned into liquid again and stored inside the storage chamber 801. The air pressure sensor 12 and the temperature sensor 17 on the inner wall of the storage chamber 801 are also used to monitor the air pressure and temperature inside the storage chamber 801 in real time.
