It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] like Figure 1-4As shown, an oil-water separation device for plant essential oil comprises a separation cylinder 1, wherein a fixed bracket 2 and a movable bracket 9 are fixedly connected from top to bottom in the separation cylinder 1, respectively; the fixed bracket 2 is fixed in the separation cylinder 1, and the movable bracket 9 is rotatable and can be lifted and lowered in the separation cylinder 1; oil-water separation membranes 3 are arranged on the opposite surfaces of the fixed bracket 2 and the movable bracket 9, and the arranged oil-water separation membranes 3 are used to squeeze the plant essential oil between the fixed bracket 2 and the movable bracket 9 when the movable bracket 9 moves toward the fixed bracket 2, so that the water in the plant essential oil quickly passes through the oil-water separation membrane on the movable bracket 9 3, that is, to achieve rapid separation of oil and water, a one-way valve 4 for pouring plant essential oil is installed on the fixed bracket 2, the one-way valve 4 is an elastic one-way valve, and is connected to a water pipe when actually used, and the plant essential oil to be separated is forced to open the one-way valve 4 with a certain pressure by the water pipe, and is injected between the fixed bracket 2 and the movable bracket 9, the surface of the movable bracket 9 is hollowed out, and the hollow part is used to install the oil-water separation membrane 3, the movable bracket 9 is located between two adjacent hollow parts and a paddle 7 is inserted, and a rectangular rod 12 is fixedly connected to the center of the bottom surface of the movable bracket 9, and the outer cover of the rectangular rod 12 is provided with a rectangular rod 12 that is rotatably connected to the bottom of the separation cylinder 1 The rectangular sleeve 11 is used to rotate the rectangular rod 12, and the movable bracket 9 drives the plurality of paddles 7 to rotate, so that the plant essential oil on the movable bracket 9 can generate centrifugal force, thereby realizing the rapid separation of oil and water in the plant essential oil, and the top edge of the side wall of the rectangular rod 12 is rotatably connected with a connecting block 16 that matches the clearance of the outer wall of the rectangular sleeve 11, the plug-in part of the rectangular rod 12 and the rectangular sleeve 11 is a block-shaped setting, and the rotatable connection part with the connecting block 16 is a cylindrical setting, so as to ensure that when the rectangular rod 12 rotates, the connecting block 16 will not interfere with the rectangular sleeve 11, and the bottom of the separation cylinder 1 is rotatably connected with the connecting block 16. The connecting block 16 is threadedly penetrated by a reciprocating screw 15 which is rotatably connected to the bottom edge of the movable bracket 9. The reciprocating screw 15 is arranged to ensure that the connecting block 16 does not rotate with the rotation of the rectangular rod 12. Moreover, through the rotational connection between the connecting block 16 and the rectangular rod 12, and the rotational connection between the reciprocating screw 15 and the bottom edge of the movable bracket 9, it is ensured that the movable bracket 9 can rotate smoothly without being restricted by the connecting block 16 and the reciprocating screw 15. Conversely, by rotating the reciprocating screw 15, the connecting block 16 can drive the rectangular rod 12 to rise and fall in the rectangular sleeve 11, thereby realizing the movement of the movable bracket 9 relative to the fixed bracket 2.

[0023] Further discussion: A spring rod 6 is fixedly connected between the bottom edge of the paddle 7 and the movable bracket 9, and a roller 8 is embedded and rotatably connected to the top edge of the paddle 7. When the movable bracket 9 rises to the point where the roller 8 contacts the oil-water separation membrane 3 on the bottom surface of the fixed bracket 2, the roller 8 rotates to ensure that the movable bracket 9 smoothly drives the paddle 7 to rotate. The spring rod 6 can also ensure that when the movable bracket 9 continues to rise, the elastic expansion and contraction of the spring rod 6 can be utilized to enable the paddle 7 to overcome the elastic force of the spring rod 6 and descend, i.e., to ensure that the movable bracket 9 can rise to fit with the fixed bracket 2.

[0024] Further discussion: The bottom of the separation cylinder 1 is fixedly connected to a motor 10 for driving the rectangular sleeve 11 to rotate, and the bottom end of the reciprocating screw 15 is fixedly connected to a driven gear 14, and the tooth surface of the driven gear 14 is meshingly connected to a gear ring 13 fixed on the main shaft of the motor 10. The motor 10 is used to drive the rectangular sleeve 11 to rotate, and then the gear ring 13 rotates to drive the driven gear 14 to rotate, and the reciprocating screw 15 rotates, so that the connecting block 16 can drive the rectangular rod 12 to reciprocate and rise and fall. In addition, the thread height on the reciprocating screw 15 is equal to the maximum distance between the fixed bracket 2 and the movable bracket 9, and the diameter of the gear ring 13 is smaller than the diameter of the driven gear 14, thereby ensuring that the reciprocating screw 15 rotates at a speed lower than the rectangular sleeve 11.

[0025] Further discussion: Drain pipes 5 are provided on the wall of the separation cylinder 1 from top to bottom at the movable bracket 9 and the bottom of the separation cylinder 1. The drain pipes 5 at the upper and lower positions are used for discharging essential oil and water, respectively. During actual use, a switch valve is installed on the drain pipe 5 to realize automatic remote control of opening and closing, thereby realizing the discharge and collection of separated water and essential oil after separation.

[0026] Working principle: the liquid to be separated enters between the fixed bracket 2 and the movable bracket 9 along the one-way valve 4, and the motor 10 is used to drive the rectangular sleeve 11 to rotate and drive the rectangular rod 12 to rotate, so that the movable bracket 9 drives several paddles 7 to rotate, so that the plant essential oil on the movable bracket 9 can generate centrifugal force, so as to realize the rapid stratification of oil and water in the plant essential oil, and in the stratification process, the gear ring 13 on the motor 10 rotates accordingly, and the rotation of the gear ring 13 drives the driven gear 14 to rotate, so as to realize the rotation of the reciprocating screw rod 15, so as to realize the connection block 16 drives the rectangular rod 12 to reciprocate and rise and fall, so as to realize the reciprocating rise and fall of the movable bracket 9, which can fix the bracket 2 and the oil-water separation membrane 3 on the surface, so that the water in the lower layer of the liquid that has been stratified on the movable bracket 9 is squeezed out and filtered through the oil-water separation membrane 3 on the movable bracket 9.
