[0042] Furthermore, the electric heating tube 11 is fixedly installed inside the extraction cylinder 7. The electric heating tube 11 has a spiral structure. A rotating structure is formed between the stirring shaft 10 and the extraction cylinder 7. The diameter of the stirring shaft 10 is smaller than the diameter of the electric heating tube 11. During use, the electric heating tube 11 is fixedly installed inside the extraction cylinder 7. The electric heating tube 11 can be heated by the heating component 20. During the heating process, the material to be extracted inside the extraction cylinder 7 can be heated, thereby improving the efficiency of the device during the extraction process.

[0043] Furthermore, the circulation pipe 12 forms a flow structure with the cooling cylinder 16 through the circulation liquid outlet pipe 15, and the cooling cylinder 16 forms a flow structure with the circulation pipe 12 through the liquid inlet pipe 17. The circulation pipe 12 is a spiral structure, and the circulation liquid outlet pipe 15 and the liquid inlet pipe 17 are both Y-shaped structures. During use, the circulation pipe 12 can heat the extracted chemical raw materials inside the extraction cylinder 7 through the liquid with a higher temperature inside. The liquid inside the circulation pipe 12 enters the cooling cylinder 16 through the circulation liquid outlet pipe 15, and then the liquid exchanges heat with the steam in the condenser 28 installed inside the cooling cylinder 16, and then flows back to the circulation pipe 12 through the liquid inlet pipe 17.

[0045] Furthermore, the stirring frame 26 forms a rotating structure with the first separation chamber 24 through the second motor 25, and the first separation chamber 24 forms a circulation structure with the condensation outlet pipe 29 through the cooperation between the steam pipe 27 and the condensation pipe 28. The condensation pipe 28 has a spiral structure.

Since the condensation pipe 28 has a spiral structure, the contact area between the condensation pipe 28 and the cooling water inside the cooling cylinder 16 can be increased, which facilitates the cooling of the steam inside the condensation pipe 28. Then, the cooled water vapor is passed into the interior of the collecting pipe 30 through the condensation outlet pipe 29 for storage. Then, the condensed water used to cool the condensation pipe 28 can heat the inside of the extraction cylinder 7 through the liquid inlet pipe 17 and the circulating liquid outlet pipe 15, thereby improving the energy utilization rate of the device.

[0046] Furthermore, the second raw material inlet pipe 31 and the condensation liquid outlet pipe 29 are fixed to each other, and a flow structure is formed between the second raw material inlet pipe 31 and the collecting pipe 30.

At the same time, the second raw material inlet pipe 31 and the condensation liquid outlet pipe 29 are fixed to the collecting pipe 30 through the same inlet, thereby improving the space utilization efficiency inside the device.

[0047] Working principle: First, the bottom seat frame 1 and the bracket on the top of the bottom seat frame 1 can be fixed together by the push rod 2 and the right bottom rod 3 on the right side, the push rod 2 is installed inside the adjustment slot 4, and then the position of the push rod 2 is fixed by the fixing bolt 5, and at the same time, the rear frame assembly 6 on the rear side inserts the clamping rod 606 into the inner cavity 601, and then during the entry of the clamping rod 606, the clamping block 605 will be squeezed by the clamping rod 606, and during the extrusion process, the two sets of clamping plates 603 are rotated by the rotating shaft 602, and during the rotation process, they will be squeezed by the spring 604, and then the clamping rod 606 continues to enter the bottom to the left, and the clamping plate 603 will return to its original position through the elastic action of the spring 604 to fix the clamping rod 606.

[0048] Therefore, the extraction component and the separation and purification component can be disassembled and installed during use, which improves the flexibility of the device during use and also facilitates maintenance and replacement of the device.

[0049] The chemical raw materials to be extracted are placed in the extraction cylinder 7 for extraction and separation. During the extraction process, the electric heating tube 11 and the circulation tube 12 can heat the raw materials inside. At the same time, the circulation tube 12 can heat the extracted chemical raw materials inside the extraction cylinder 7 through the liquid with a higher temperature inside. The liquid inside the circulation tube 12 enters the cooling cylinder 16 through the circulation liquid outlet tube 15, and then the liquid exchanges heat with the steam in the condenser 28 installed inside the cooling cylinder 16, and then flows back to the circulation tube 12 through the liquid inlet tube 17. At this time, the liquid temperature inside the circulation tube 12 is relatively high, which can heat the material inside the extraction cylinder 7. The circulation tube 12 and the electric heating tube 11 cooperate with each other to heat the inside of the extraction cylinder 7, which can save energy, and the electric heating tube 11 can be turned off for heating at some times, thereby improving the efficiency of energy utilization inside the device and making the device more resource-saving.

[0050] After that, the material liquid outlet pipe 13 and the raw material pipeline 21 are fixed together, and the raw material that has been extracted in the extraction cylinder 7 can be passed to other locations through the material liquid outlet pipe 13 and the raw material pipeline 21, and then the raw material pipeline 21 is divided through the first branch pipe 22 and the second branch pipe 23 on the right according to the characteristics of the chemical raw material, and the material passed into the first separation chamber 24 through the first branch pipe 22 is distilled, purified and separated, and then the material diverted through the second branch pipe 23 can be separated in other ways, and then the raw material in the first separation chamber 24 is evaporated into water vapor. The water vapor distilled in the first separation chamber 24 enters into the condenser 28 through the steam pipe 27. Since the condenser 28 is a spiral structure, the contact area between the condenser 28 and the cooling water in the cooling cylinder 16 can be increased, so that the steam in the condenser 28 can be cooled conveniently. Then, the cooled water vapor is passed into the collecting tube 30 through the condensation liquid outlet pipe 29 for storage. Then, the condensed water used to cool the condenser 28 can be heated to the inside of the extraction cylinder 7 through the liquid inlet pipe 17 and the circulating liquid outlet pipe 15, so as to improve the energy utilization rate of the device.
