Description

TECHNICAL FIELD

[0001] The utility model relates to extraction device technical field, concretely is a kind of environment-friendly biological enzyme auxiliary extraction extraction device. BACKGROUND

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that separates mixtures by taking advantage of the different solubilities of components in solvents. With the improvement of environmental protection consciousness and the rapid development of biotechnology, the extraction and utilization of natural products have become a research hotspot. Traditional extraction methods such as solvent extraction, distillation and pressing not only have low efficiency but also may cause environmental pollution. Currently, in order to achieve efficient extraction and reduce environmental pollution, biological enzyme auxiliary extraction operation is usually used for extraction.

[0003] After searching, a device for extracting steviol glycosides from biological enzyme fermentation broth with application number 202120868702.7 was found. The device has the advantages of preventing blockage and uniform heating by the cooperation of heating wires, filter boxes, filter plates, electric telescopic rods, brushes, reaction kettles, cavities, electromagnetic valves, fans and control panels. It solves the problem of uneven heating and poor heating effect of existing steviol glycoside extraction devices, which are usually heated by heating blocks. However, in actual application, when steam is dispersed in the reaction kettle interlayer to heat the reaction kettle, high-temperature steam first heats the reaction kettle. After the reaction kettle is heated, the temperature is transmitted to the raw materials to heat them. The heating efficiency is relatively low, which leads to uneven heating of the raw materials in the reaction kettle. At the same time, during the steam dispersion process, part of the steam condenses into water and accumulates at the bottom of the interlayer, which cannot be discharged. SUMMARY

[0004] Therefore, the utility model aims to provide an environment-friendly biological enzyme auxiliary extraction extraction device to solve the technical problems in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an environment-friendly biological enzyme auxiliary extraction extraction device, comprising a reaction kettle and an oil storage tank. A stirring rod is installed inside the reaction kettle, and the stirring rod penetrates the top of the reaction kettle.

[0010] Further, the stirring rod and the stirring blade are both hollow, and the stirring blade is in communication with the stirring rod.

[0011] By adopting the technical scheme, under the driving of the rack, the extrusion rod drives the piston to reciprocate in the extrusion box. Through the cooperation of the piston and the extrusion box, the heat-conducting oil in the oil storage tank is delivered to the inside of the stirring rod and the stirring blade through the delivery of the first oil delivery pipe, the second oil delivery pipe, the third oil delivery pipe and the fourth oil delivery pipe. Thus, the raw materials in the reaction kettle are heated more uniformly.

[0012] Further, one end of the first oil delivery pipe and the fourth oil delivery pipe is connected with the oil storage tank.

[0013] By adopting the technical scheme, under the driving of the air cylinder output end, the rack engages with the gear, the stirring rod drives the stirring blade to stir the raw materials in the reaction kettle, and the extrusion rod drives the piston to reciprocate, the heat-conducting oil in the oil storage tank is replaced with the heat-conducting oil in the stirring blade. Thus, the raw materials do not need to be heated through the reaction kettle to conduct heat to the raw materials, and the heating efficiency of the raw materials is improved.

[0014] Further, the first oil delivery pipe, the second oil delivery pipe, the third oil delivery pipe and the fourth oil delivery pipe are all provided with electromagnetic one-way valves on the outer surfaces.

[0015] By adopting the technical scheme, when the piston moves towards the cylinder, the electromagnetic check valves on the first oil pipe and the fourth oil pipe are opened at this time, the heated heat conducting oil in the oil storage tank is sucked into the extrusion box, and the heat conducting oil in the extrusion box is extruded into the oil storage tank through the fourth oil pipe, when the piston moves towards the first oil pipe, the electromagnetic check valves on the second oil pipe and the third oil pipe are opened at this time, the heated heat conducting oil in the extrusion box enters the stirring rod and the stirring blade through the second oil pipe, and the heat conducting oil in the stirring rod and the stirring blade enters the extrusion box through the third oil pipe, the heat conducting oil in the stirring blade is circulated with the heat conducting oil in the oil storage tank through the above-mentioned mode, and the temperature of the heat conducting oil in the stirring blade is always controlled within a certain range.

[0018] Further, the extrusion rod penetrates through one side of the extrusion box and is slidingly connected with the extrusion box.

[0019] By adopting the technical scheme, under the driving of the rack, the extrusion rod drives the piston to reciprocate in the extrusion box, so that the piston circulates and replaces the heat conducting oil in the oil storage tank and the heat conducting oil in the stirring blade, without the need of an additional power device, thereby reducing energy consumption and making the device more environmentally friendly.

[0020] Further, the control panel is mounted on the outer surface of the oil storage tank, and the heating block, the electromagnetic valve, the electromagnetic check valve and the cylinder are electrically connected with the control panel.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. This utility model is equipped with an extrusion box, a piston and an extrusion rod. Driven by a rack and pinion, the extrusion rod drives the piston to move back and forth, replacing the heated heat transfer oil in the oil storage tank with the heat transfer oil in the stirring blade. This allows the heat transfer oil to circulate between the stirring blade and the oil storage tank, thus eliminating the need to heat the reactor to transfer heat to the raw materials, improving the heating efficiency of the raw materials, and preventing the condensate from remaining in the reactor jacket and being unable to drain.

[0024] 2. This utility model is equipped with a rack, gear, stirring rod, and stirring blade. When the operator starts the cylinder, the cylinder output end drives the rack to move back and forth. Through the meshing of the rack and gear, the stirring rod drives the stirring blade to rotate. The stirring blade stirs the raw materials and biological enzymes in the reaction vessel, ensuring that the biological enzymes and raw materials are in full contact. At the same time, during stirring, the heat dissipated by the heat transfer oil heats the raw materials, making the raw materials more evenly heated. This avoids uneven heating, which would reduce the activity of biological enzymes and affect the reaction efficiency. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1: An environmentally friendly bio-enzyme-assisted extraction device, such as...Figures 1-4 As shown, the reactor includes a reaction vessel 1 and an oil storage tank 2. A stirring rod 9 is installed inside the reaction vessel 1, extending through the top of the reaction vessel 1. A first bushing 10 and a second bushing 19 are connected to both ends of the stirring rod 9. A stirring blade 11 and a gear 20 are installed on the outer surface of the stirring rod 9. A cylinder 6 is installed on one side of the top of the reaction vessel 1, and a rack 7 is connected to the output end of the cylinder 6. A compression chamber 12 is installed on the top of the oil storage tank 2. A piston 13 is connected inside the compression chamber 12, and a compression rod 8 is connected to one side of the piston 13. One end of the compression rod 8 is connected to the rack 7. The first oil supply pipe 14, the second oil supply pipe 15, the third oil supply pipe 16 and the fourth oil supply pipe 17 are connected to both sides of the reactor 1 respectively. The top of the reactor 1 is equipped with a feed pipe 3 and an addition pipe 4. The discharge port of the reactor 1 is equipped with a solenoid valve 5. The operator adds the raw material into the reactor 1 through the feed pipe 3, and then adds the biological enzyme into the reactor 1 through the addition pipe 4. The biological enzyme acts as a catalyst to accelerate the extraction speed of steviol glycosides. The opening time of the discharge port of the reactor 1 is controlled by the solenoid valve 5. The extracted mixture leaves from the discharge port of the reactor 1.

[0033] See Figure 1 and Figure 2 In the above embodiment, gear 20 meshes with rack 7, and stirring rod 9 is rotatably connected to reactor 1. The operator starts cylinder 6 through control panel 22. The output end of cylinder 6 drives rack 7 to move back and forth. Through the meshing of rack 7 and gear 20, stirring rod 9 drives stirring blade 11 to rotate. Stirring blade 11 stirs the raw materials and biological enzymes in reactor 1, so that biological enzymes and raw materials are in full contact, thereby accelerating the enzymatic hydrolysis reaction rate of biological enzymes on raw materials.

[0034] See Figure 4 In the above embodiment, both the stirring rod 9 and the stirring blade 11 are hollow, and the stirring blade 11 is connected to the stirring rod 9. Driven by the rack 7, the extrusion rod 8 drives the piston 13 to reciprocate within the extrusion box 12. Through the cooperation of the piston 13 and the extrusion box 12, the heat transfer oil in the oil storage tank 2 is transported to the interior of the stirring rod 9 and the stirring blade 11 via the first oil supply pipe 14, the second oil supply pipe 15, the third oil supply pipe 16 and the fourth oil supply pipe 17, thereby making the raw materials in the reactor 1 more evenly heated.

[0035] See Figure 1 and Figure 2In the above embodiment, one end of the first oil supply pipe 14 and the fourth oil supply pipe 17 are both connected to the oil storage tank 2. Driven by the output end of the cylinder 6, the cylinder 7 meshes with the gear 20, so that the stirring rod 9 drives the stirring blade 11 to stir the raw materials in the reactor 1, and pushes the extrusion rod 8 to drive the piston 13 to move back and forth, so as to replace the heat transfer oil in the oil storage tank 2 with the heat transfer oil in the stirring blade 11, thereby eliminating the need to transfer heat to the raw materials by heating the reactor 1, and improving the heating efficiency of the raw materials.

[0036] See Figure 1 and Figure 2 In the above embodiment, electromagnetic check valves 18 are installed on the outer surfaces of the first oil supply pipe 14, the second oil supply pipe 15, the third oil supply pipe 16, and the fourth oil supply pipe 17. When the piston 13 moves toward the cylinder 6, the electromagnetic check valves 18 on the first oil supply pipe 14 and the fourth oil supply pipe 17 open, and the heated heat transfer oil in the oil storage tank 2 is drawn into the extrusion box 12. At the same time, the heat transfer oil in the extrusion box 12 is squeezed into the oil storage tank 2 through the fourth oil supply pipe 17. When the piston 13 moves toward the first oil supply pipe 14... When moving, the electromagnetic check valves 18 on the second oil supply pipe 15 and the third oil supply pipe 16 are opened. The heated heat transfer oil in the extrusion box 12 enters the stirring rod 9 and the stirring blade 11 through the second oil supply pipe 15. At the same time, the heat transfer oil in the stirring rod 9 and the stirring blade 11 enters the extrusion box 12 through the third oil supply pipe 16. In this way, the heat transfer oil in the stirring rod 9 and the stirring blade 11 is circulated with the heat transfer oil in the oil storage tank 2, so that the temperature of the heat transfer oil in the stirring blade 11 is always controlled within a certain range.

[0037] See Figures 1-4 In the above embodiment, one end of the second oil pipe 15 is rotatably connected to the second bushing 19, and one end of the third oil pipe 16 is rotatably connected to the first bushing 10. Driven by the rack 7, the gear 20 drives the stirring rod 9 to rotate. The first bushing 10 and the second bushing 19 are rotatably connected to the third oil pipe 16 and the second oil pipe 15 respectively, thereby avoiding the third oil pipe 16 and the second oil pipe 15 from rotating with the stirring rod 9 and affecting the practicality of the device.

[0038] See Figure 1 and Figure 2 In the above embodiment, the extrusion rod 8 passes through one side of the extrusion box 12 and is slidably connected to the extrusion box 12. Driven by the rack 7, the extrusion rod 8 drives the piston 13 to reciprocate within the extrusion box 12, so that the piston 13 circulates and replaces the heat transfer oil in the oil storage tank 2 and the heat transfer oil in the stirring blade 11. No additional power device is required, thereby reducing energy consumption and making the device more environmentally friendly.

[0039] Example 2: To improve production efficiency, Example 2 is an improvement on Example 1. (See attached document.) Figure 1 andFigure 2 The outer surface of the oil storage tank 2 is equipped with a control panel 22, and the heating block 21, solenoid valve 5, solenoid check valve 18 and cylinder 6 are all electrically connected to the control panel 22. The operator controls the heating block 21, solenoid valve 5, solenoid check valve 18 and cylinder 6 through the control panel 22, thereby accurately controlling the temperature of the heat transfer oil and the opening timing of solenoid check valve 18 and solenoid valve 5, and improving production efficiency.

[0040] The implementation principle of this utility model is as follows: The operator adds raw materials into the reaction vessel 1 through the feed pipe 3, then adds biological enzymes into the reaction vessel 1 through the addition pipe 4, and simultaneously activates the heating block 21 and the cylinder 6. The heating block 21 heats the heat transfer oil in the oil storage tank 2. The output end of the cylinder 6 drives the rack 7 to reciprocate. Through the meshing of the rack 7 and the gear 20, the stirring rod 9 drives the stirring blade 11 to rotate, stirring the raw materials in the reaction vessel 1. Simultaneously, driven by the rack 7, the extrusion rod 8 drives the piston 13 to reciprocate within the extrusion chamber 12. When the piston 13 moves towards the cylinder 6, the electromagnetic check valves 18 on the first oil supply pipe 14 and the fourth oil supply pipe 17 open, and the heated heat transfer oil in the oil storage tank 2 is drawn into the extrusion chamber 12. The heat transfer oil in the extrusion chamber 12 is squeezed into the storage tank 2 through the fourth oil supply pipe 17. When the piston 13 moves towards the first oil supply pipe 14, the electromagnetic check valves 18 on the second oil supply pipe 15 and the third oil supply pipe 16 are opened. The heated heat transfer oil in the extrusion chamber 12 enters the stirring rod 9 and the stirring blade 11 through the second oil supply pipe 15. At the same time, the heat transfer oil in the stirring rod 9 and the stirring blade 11 enters the extrusion chamber 12 through the third oil supply pipe 16, thereby circulating the heat transfer oil in the storage tank 2 and the heat transfer oil in the stirring blade 11. This allows the stirring blade 11 to heat the raw material through the heat dissipated by the heat transfer oil while stirring the raw material. After extraction, the electromagnetic valve 5 is opened, and the extracted mixture leaves from the outlet of the reactor 1 for subsequent processing.
