[0002] The mixing and clarifying extraction box is widely used in the field of extraction. Its mixing chamber adopts a large mixing tank and a semi-open six-blade disc turbine, and uses the centrifugal force of the turbine to pump and mix the two phases. After the mixing is completed, it enters the clarifying chamber for phase separation, and then the two phases flow back through the interstage pipe located at the bottom of the extraction box. At present, the above-mentioned extraction equipment has a wide range of applications, but there are the following problems in the application process: First, because the mixing chamber occupies a large area of ​​the box, the area of ​​the clarifying chamber cannot be further expanded, the clarification capacity is limited, and the production capacity potential of the extraction box cannot be further explored. Second, the structural form of the mixing chamber combined with the semi-open six-blade disc turbine has a low pumping and mixing efficiency, which affects the extraction stage efficiency and extraction flux. Third, the interstage pipe is arranged below the bottom plate of the extraction phase, and leakage is frequent, affecting the working environment. In view of the above problems, the structure of the extraction box is reasonably optimized on the basis of the existing equipment, which has significant economic and safety and environmental value potential.

DETAILED DESCRIPTION

[0017] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0018] The present invention is further described below in conjunction with the embodiments and drawings:

[0019] Example 1: Figure 1-4 As shown, the embodiment of the utility model discloses a high-efficiency clarification type extraction device without mixing chamber, including a multi-stage extraction box connected together front and back, each extraction box includes a clarification chamber 1, an aqueous phase box 2, an organic phase box 3, an organic phase interstage pipe 4, an aqueous phase interstage pipe 5, a lifting mixer 6, a mixing tee 9, a multi-chamber mixer 7 and a reflux pipe 8, the clarification chamber 1 is provided with an aqueous phase box 2 on the left side, and the clarification chamber 1 on the right side of the aqueous phase box 2 is provided with an organic phase box 3; the clarification chamber 1 is provided with an organic phase interstage pipe 4, an aqueous phase interstage pipe 5, a lifting mixer 6, a mixing tee 9, a multi-chamber mixer 7 and a reflux pipe 8, the clarification chamber 1 is provided with an aqueous phase box 2 on the left side, and the clarification chamber 1 is provided with an organic phase box 3 on the right side of the aqueous phase box 2; the clarification chamber 1 is provided with an organic phase interstage pipe 4, an aqueous phase interstage pipe 5, a lifting mixer 6, a mixing tee 9, a multi-chamber mixer 7 and a reflux pipe 8, The inter-stage pipe 4 and the aqueous phase inter-stage pipe 5, the left end of the organic phase inter-stage pipe 4 passes through the clarification chamber 1 and is fixedly connected with the organic phase box 3 of the upper extraction box, the left end of the aqueous phase inter-stage pipe 5 passes through the clarification chamber 1 and is fixedly connected with the aqueous phase box 2 of the lower extraction box, the right end of the organic phase inter-stage pipe 4 and the right end of the aqueous phase inter-stage pipe 5 are both fixedly connected with the liquid inlet of the lifting mixer 6 through the mixing tee 9, the liquid outlet of the lifting mixer 6 is fixedly connected with the multi-cavity mixer 7, and the output port of the multi-cavity mixer 7 is fixedly connected with the clarification chamber 1 through the reflux pipe 8.

[0020] The multi-cavity mixer 7 is a 90° cross layout of spirals and rectangular block arrays, and different rectangular block arrays are cross-arranged at 90° to form multiple mixing cavities. At the same time, channels are provided in the cavities to ensure full mixing of the two phases and smooth flow.

[0021] like Figure 3As shown, the lifting mixer 6 includes a mixing chamber 10, a motor 11, a coupling 12, and a bearing 13. The motor 11 is arranged above the mixing chamber 10, and the output end of the motor 11 is fixedly connected to the rotating shaft 14 through the coupling 12. The bearing 13 is fixedly installed at the center of the upper side of the mixing chamber 10. The lower end of the rotating shaft 14 passes through the bearing 13 and extends to the inner bottom end of the mixing chamber 10. A sealing ring 28 is provided at the connection between the rotating shaft 14 and the mixing chamber 10. A power impeller 15 is fixedly connected to the lower end of the rotating shaft 14. A static mixing impeller 16 is mounted on the outer side of the rotating shaft 14 above the power impeller 15. A positioning ring 17 fixedly connected to the static mixing impeller 16 is provided in the mixing chamber 10 above the static mixing impeller 16.

[0022] The positioning ring 17 is used to fix the static mixing impeller 16 to prevent the static mixing impeller 16 from rotating during the mixing process of the power impeller 15 .

[0023] Among them, the static mixing impeller 16 can be located in the mixing chamber 10 between the liquid inlet and the liquid outlet of the lifting mixer 6; when working, the motor 11 is started, and the motor 11 drives the rotating shaft 14 to rotate, thereby driving the power impeller 15 to rotate, and the power impeller 15 continuously lifts and mixes the organic phase and the aqueous phase, and the static mixing impeller 16 performs turbulent mixing to improve the mixing efficiency.

[0024] like Figure 1-2 As shown, it also includes a porous plate 18 and a first baffle plate 19. The porous plate 18 distributed in the front-to-back direction and consistent with the front-to-back width of the clarification chamber 1 is provided on the right side of the clarification chamber 1, and the first baffle plate 19 is provided on the left side of the porous plate 18.

[0025] Therefore, when the two-phase mixed liquid flows out through the reflux pipe 8 and enters the clarification chamber 1, it enters the porous plate 18 under the action of the first baffle plate 19, and the porous plate 18 cooperates with the first baffle plate 19 to slow down the flow rate of the two phases, thereby promoting rapid clarification of the two-phase mixed liquid.

[0026] like Figure 1-2 As shown, a second baffle 20 distributed in the front-to-back direction is provided on the right side of the organic phase box 3, and an organic phase outlet 21 extending to the front of the clarification chamber 1 is fixedly connected to the front side of the organic phase box 3, and the organic phase outlet 21 is fixedly connected to the organic phase interstage pipe 4 of the lower extraction box.

[0027] Thus, after the two-phase mixed liquid is layered in the clarification chamber 1, the organic phase is located in the upper layer, and the upper organic phase flows over the second baffle plate 20 and enters the organic phase box 3 for use in the next-stage extraction box.

[0028] like Figure 1-2As shown, a third baffle plate 22 distributed in the front-to-back direction is provided on the right side of the water phase box 2, and the height of the third baffle plate 22 is higher than the height of the second baffle plate 20, and the lower end of the third baffle plate 22 extends to the bottom of the water phase box 2; a water phase overflow pipe 23 with a closed lower end is fixedly connected to the bottom of the water phase box 2, a water phase overflow port 24 is fixedly opened on the outer side of the water phase overflow pipe 23, and a water phase discharge port 25 extending to the rear of the clarification chamber 1 is fixedly connected to the rear side of the water phase box 2, and the water phase discharge port 25 is fixedly connected to the water phase interstage pipe 5 of the upper extraction box.

[0029] By setting the height of the third baffle plate 22 higher than the height of the second baffle plate 20, the organic phase is prevented from flowing over the third baffle plate 22 and entering the water phase box 2; by setting the lower end of the third baffle plate 22 to extend below the water phase box 2 and having a small distance from the bottom of the clarification chamber 1, it is convenient for the water phase to pass through the bottom of the third baffle plate 22 and enter the water phase box 2, while preventing the organic phase from entering the water phase box 2.

[0030] Thus, after the two-phase mixed liquid is separated into layers in the clarification chamber 1, the water phase is located in the lower layer, and the lower water phase enters the water phase box 2 through the water phase overflow port 24 and the water phase overflow pipe 23 to be used in the upper extraction box.

[0031] like Figure 1-2 As shown, an observation port 1 26 is provided on the left side of the upper part of the clarification chamber 1, and an observation port 2 27 is provided on the right side of the upper part of the clarification chamber 1. Thus, it is convenient to observe the inside of the clarification chamber 1.

[0032] Example 2: The present utility model embodiment discloses a high-efficiency clarification extraction method without a mixing chamber, comprising the following steps:

[0033] The organic phase interstage pipe 4 of the current extraction box is connected to the organic phase box 3 of the upper extraction box, and the organic phase enters the organic phase interstage pipe 4 from the upper extraction box; the water phase interstage pipe 5 of the current extraction box is connected to the water phase box 2 of the lower extraction box, and the water phase enters the water phase interstage pipe 5 from the lower extraction box;

[0034] The organic phase and the aqueous phase in the organic phase interstage pipe 4 and the aqueous phase interstage pipe 5 are collected in the mixing tee 9 and enter the lifting mixer 6, which continuously lifts and mixes them. After the mixing is completed, they enter the multi-chamber mixer 7 for collision mixing. After the multi-stage mixed extraction is completed, they enter the clarification chamber 1 of the extraction box of this stage through the reflux pipe 8;

[0035] The first baffle plate 19 and the porous plate 18 in the clarification chamber 1 slow down the flow rate of the two phases to promote rapid clarification, and then the two phases are separated in the clarification chamber 1, the organic phase flows over the second baffle plate 20 into the organic phase box 3, and the water phase flows through the water phase overflow port 24 and the water phase overflow pipe 23 into the water phase box 2;

[0036] The aqueous phase in the aqueous phase box 2 is discharged to the upper extraction box, and the organic phase in the organic phase box 3 is discharged to the lower extraction box, forming a multi-stage combined extraction process.

[0037] In summary, the utility model has a simple structure and is easy to use. It is connected together through multi-stage extraction boxes, and each stage of the extraction box is connected to the lifting mixer 6 and the multi-cavity mixer 7 to achieve multi-stage mixing and rapid extraction, thereby solving the problems of low mixing efficiency and poor clarification effect of the mixing chamber in the existing mixing and clarifying extraction box. At the same time, by eliminating the traditional mixing chamber and increasing the area of ​​the clarification chamber 1, the clarification capacity is significantly improved; further, by embedding the layout of the interstage pipe, the environmental hazards of leakage are eliminated, and the production capacity of the traditional extraction equipment is fully tapped while improving the on-site working environment.
