[0020] Please see Figure 1-3 A multifunctional extraction tank for preparing Sichuan pepper essential oil includes an explosion-proof tank body 1. An explosion-proof door 4 is connected to one side of the front end of the explosion-proof tank body 1 via a hinge 3. The explosion-proof tank body 1 and the explosion-proof door 4 provide the extraction tank with explosion-proof functionality. Tank feet 2 are provided on both sides of the bottom of the explosion-proof tank body 1. A heating element 5 is located on the left side inside the explosion-proof tank body 1. An outer liner 6 is inserted into the top of the heating element 5. An inner liner 7 is located inside the outer liner 6. A sealing piston 8 is plugged into the top of the inner liner 7. The top of the explosion-proof tank 1 is connected to a connecting pipe 9. A condenser pipe 11 is installed on the right side inside the explosion-proof tank 1. The end of the connecting pipe 9 is connected to the air inlet 16 at the top of the condenser pipe 11 through a detachable connector 10. An essential oil collection bottle 15 is installed directly below the liquid outlet 17 at the bottom of the condenser pipe 11. A water inlet 12 is installed on the upper right side of the condenser pipe 11. A water outlet 13 is installed on one side of the bottom of the condenser pipe 11. A heat insulation plate 18 is installed inside the explosion-proof tank 1 and between the heating stove body 5 and the condenser pipe 11.
[0021] A valve 14 is installed on the outlet 13.
[0022] The inner liner 7 is in contact with the outer liner 6, but the two are not connected. The inner liner 7 and the outer liner 6 are designed so that the glass inner liner or the stainless steel inner liner can be replaced according to the preparation type, which can adapt to different extraction methods and make it replaceable, thus enhancing its functionality.
[0023] The condenser pipe 11 is connected to the inner wall of the explosion-proof tank 1 via a support rod at the middle right side.
[0024] The explosion-proof tank 1 is covered with a heat insulation mesh 19 on the top, and the upper end of the water inlet 12 passes through the heat insulation mesh 19, and the top of the water inlet 12 passes through the heat insulation mesh 19.
[0025] Among them, the connecting pipe 9 has an inverted U-shaped structure.
[0026] The working principle and usage process of this utility model are as follows: First, when working, open the sealing piston 8 at the top of the inner liner 7, pour the crushed peppercorns into the inner liner 7, and add an appropriate amount of water, the amount of water should be enough to submerge the peppercorns. Then, the heating source set in the heating stove body heats the inner liner 7 and the outer liner 6, so that the generated water vapor enters the condenser tube 11 through the connecting pipe 9. At the same time, cooling water is injected into the condenser tube 11 through the water inlet 12 and discharged from the water outlet 13. The peppercorn essential oil formed after the water vapor cools flows into the essential oil collection bottle 15 through the liquid outlet 17 for collection.
[0027] By setting up an explosion-proof tank body 1 and an explosion-proof door 4, the extraction tank is equipped with an explosion-proof function. By setting up an inner liner 7 and an outer liner 6, the inner liner can be replaced with either a glass inner liner or a stainless steel inner liner according to the preparation type, which can adapt to different extraction methods and make it replaceable, thus enhancing its functionality. When replacing the inner liner 7, the sealing piston 8 is removed from the inner liner 7 and pulled out from the outer liner 6, and then the required glass inner liner or stainless steel inner liner is inserted. The contents not described in detail in this specification are prior art known to those skilled in the art.
