[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0017] A turbine extractor, provided with a tower body 1, the tower body 1 is divided into upper section a, middle section b, lower section c, the lower section c is provided with heavy phase outlet 2 in lower part, light phase inlet 3 in upper part, the upper section is provided with light phase outlet 4 in upper part, heavy phase inlet 5 in lower part;Tower body is provided with stirring device 6 at the center, the stirring shaft 7 of stirring device 6 extends from the upper section of tower body to the middle section of tower body from top to bottom, the paddle of stirring shaft 7 is uniformly distributed in the middle section of tower body, and sieve plate 8 is arranged between the paddles;The outer wall of the lower section of the tower body is provided with a jacket 9, and a coil pipe 10 is further arranged between the jacket 9 and the lower section of the tower body 1, and a drain port 11 is arranged on the lower end surface of the jacket.

[0018] The overall structure of the sieve plate 8 is ladder-shaped, the sieve plate is made by stacking welding of different diameter hole rings 81, and the height of the center of the sieve plate gradually decreases from inside to outside, the center hole 82 of the sieve plate is sleeved on the outer end of the stirring shaft, the outermost circumference of the sieve plate 8 is provided with a positioning hole 83, and the upper end and the lower end of the positioning rod 84 are fixed in the tower body 1, the positioning rod 84 passes through the positioning hole 83 of the sieve plate, and the sieve plate is fixed in the tower body 1.

[0019] The medium discharge pipe 12 is arranged in the middle part of the middle section of the tower body, and the medium discharge pipe is returned to the upper section a of the tower body 1 through the lifting pump, and the upper end of the medium discharge pipe is arranged between the light phase outlet 4 and the heavy phase inlet 5.

[0020] The working principle of the utility model is: when liquid-liquid extraction operation is carried out, the heavy phase enters the tower body from the lower heavy phase inlet of the upper section of the tower body, and the light phase enters from the upper light phase inlet of the lower section of the tower body. The stirring shaft of the stirring device drives the paddle of the middle section to rotate, the medium layer of the middle section is moderate in density, is suitable for mixing with light phase and heavy phase medium, plays a premixing role, reduces the possibility of forming local non-uniform area of light phase and heavy phase in the tower, and speeds up the starting speed of extraction reaction. After the paddle mixes the heavy phase and the light phase for a period of time, the medium discharge pipe can be closed, that is, the formal liquid-liquid extraction is started. When the heavy phase and the light phase pass through the sieve plate during stirring, they can contact each other at each level of the sieve plate instead of a single plane. The sieve plate between the paddles plays the role of prolonging the contact time on the one hand, and on the other hand, due to the ladder-shaped structure, it can guide the mixed liquid to form a specific flow pattern. After the light phase medium passes through the sieve plate as a whole, it will flow upwards, the ladder-shaped structure can accelerate the flow speed of the light phase medium, so that the heavy phase and the light phase are fully mixed.

[0021] The jacket and the coil pipe of the outer wall of the lower section of the tower body can adjust the temperature of the entering heavy phase and light phase as required, so as to provide a suitable temperature environment for the extraction process. Under the joint action of stirring and temperature, the target substances in the heavy phase and the light phase are exchanged and separated, the coil pipe can heat the lower section of the tower body, and the jacket is provided with condensed water to ensure that the temperature of the lower section of the tower body can be accurately controlled, so as to provide a suitable temperature condition for the extraction process.

[0022] The light phase after extraction gradually rises under the action of buoyancy, etc., and is discharged from the upper light phase outlet of the upper section of the tower body; the heavy phase gradually descends under the action of gravity, enters the upper section from the lower heavy phase inlet of the upper section of the tower body, and then descends to the middle section, and is finally discharged from the lower heavy phase outlet of the lower section of the tower body.
