Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal extraction devices, in particular to a centrifugal extraction device capable of removing precipitation. Background Art

[0002] The centrifugal extractor is a high-efficiency liquid-liquid extraction device, which can make the mixing and separation of logistics have higher performance than general equipment. General equipment is not easy to mix two systems with a large difference in specific gravity, while the centrifugal extractor has a powerful mixing function, which can fully mix the two-phase logistics, so that the two-phase logistics can easily react or transfer mass, and it is also easy to separate systems with a small difference in specific gravity or high viscosity. This is because the separation of the centrifugal extractor relies on the centrifugal force that is hundreds of times greater than gravity.

[0003] In the extraction process of D-lactic acid, magnesium lactate is extracted from aqueous solution to butanol phase to become free acid, and then free lactic acid is back-extracted into aqueous solution to become sodium lactate. During the whole process, magnesium hydroxide precipitation will be produced. Although impurities are removed before entering the centrifugal extractor, when using the centrifugal extractor for extraction, as the mixing degree of the extract increases or the temperature changes during the extraction process, the precipitation in the extract may increase. When the centrifugal extractor discharges liquid, the precipitation will be discharged together with the liquid, thereby blocking the liquid outlet pipe and affecting normal liquid discharge. At present, in order to prevent the problem of clogging of the liquid outlet pipe, a filter device is generally set on the liquid outlet pipe, but the filter device needs to be replaced regularly, which requires increased labor and consumables expenses.

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a centrifugal extraction device with removable precipitates.

[0005] According to the technical solution provided in the embodiment of the present application, a centrifugal extraction device with removable precipitates includes an equipment body, wherein the equipment body is composed of an extraction chamber and a precipitate removal chamber, the extraction chamber is arranged at the upper end of the equipment body, and the precipitate removal chamber is arranged at the lower end, the stirring device A arranged in the extraction chamber and the stirring device B arranged in the precipitate removal chamber share the same rotating shaft, the precipitate removal chamber gathers the precipitate in the sedimentation collection chamber at the lower end of the precipitate removal chamber through the stirring of the stirring device B, the precipitate removal chamber is connected with the extraction chamber through the through hole above the extraction chamber, and the extraction chamber realizes the extraction of liquids of different densities from different liquid outlets through the centrifugal stirring of the stirring device A.

[0006] Furthermore, a liquid inlet is provided on the sediment removal chamber to achieve liquid inlet.

[0007] Furthermore, the sediment removal chamber realizes centrifugal sedimentation through the cyclone separation principle.

[0008] Furthermore, the through hole is located at the center of the extraction chamber, and the rotating shaft passes through the through hole via the bearing and the connecting rod, so that the liquid in the sediment removal chamber enters the extraction chamber.

[0009] Furthermore, a light phase weir plate, a heavy phase weir plate, a dispersion plate, a heavy phase liquid outlet and a light phase liquid outlet are arranged in the extraction chamber to realize the separation and extraction of the light phase and heavy phase liquids.

[0010] Furthermore, the sedimentation chamber is detachably connected to the sedimentation removal chamber, which is convenient for manual impurity removal.

[0011] Furthermore, the sedimentation chamber is connected to the sedimentation removal chamber by threads, which is convenient and quick to use.

[0012] Furthermore, the device body is fixedly supported by a shock-proof bracket, which reduces the vibration of the device body during operation and ensures smooth operation of the device.

[0013] In summary, the beneficial effects of the present application are as follows: the present application device, according to the centrifugal sedimentation principle used for mud-water separation, first performs centrifugal sedimentation on the extract entering the centrifugal extraction chamber, removes the precipitate appearing in the extract, and then uses the centrifugal extraction principle to separate the light phase and the heavy phase of the obtained clear liquid, thereby realizing extraction separation; the present device can greatly reduce the probability of clogging the liquid outlet pipe when the precipitate flows through the liquid outlet pipe with the extract, thereby reducing the cost of labor and various consumables.

It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] A centrifugal extraction device with removable precipitate, such as Figure 1 and Figure 2 As shown, an extraction chamber 2 is arranged at the upper end of the equipment body 1, and a sediment removal chamber 3 is arranged at the lower end, the extraction chamber 2 is fixed to the upper end surface of the sediment removal chamber 3, and the extraction chamber 2 is communicated with the sediment removal chamber 3 through a through hole 22 in the middle part of the lower end surface thereof, the stirring device A21 arranged in the extraction chamber 2 and the stirring device B31 in the sediment removal chamber 3 share a rotating shaft 4, the upper end of the rotating shaft 4 is fixedly connected to the top end surface of the extraction chamber 2 through a bearing, and the motor shaft of the rotating motor fixed to the top end surface of the extraction chamber 2 is fixedly connected to the rotating shaft 4;

[0022] like Figure 3 As shown, the rotating shaft 4 passes through the through hole 22 through a bearing and a connecting rod, that is, a bearing is fixedly sleeved on the rotating shaft 4, and the outer end surface of the bearing is fixedly connected to the inner end surface of the through hole 22 through a circular connecting rod. Similarly, the lower end of the rotating shaft 4 is connected to the inner wall of the sediment removal chamber 3 through a bearing and a connecting rod, so that the rotating shaft 4 can drive the stirring device A21 and the stirring device B22 to rotate in the extraction chamber 2 and the sediment removal chamber 3 respectively through the rotating motor;

[0023] like Figure 1 and Figure 2 As shown, a liquid inlet 32 ​​is arranged at the upper end of the sedimentation removal chamber 3, and two different liquid outlets are divided at the upper end of the extraction chamber 2 by a light phase weir plate and a heavy phase weir plate, respectively extracting light liquid and heavy liquid to achieve extraction separation.

[0024] Before use, start the rotating motor to rotate the stirring device B31 and the stirring device A21, and then let the mixed liquid with the extractant enter the sedimentation removal chamber 3 through the liquid inlet 32. According to the principle of centrifugal sedimentation, the liquid entering the sedimentation removal chamber 3 moves downward in a spiral in the sedimentation removal chamber 3. At the same time, under the rotation of the stirring device B31, the precipitate will be deposited at the lower part of the sedimentation removal chamber 3, and the liquid will overflow to the upper end of the sedimentation removal chamber 3 and enter the extraction chamber 2 from the through hole 22 above the sedimentation removal chamber 3. Since the stirring shaft 4 in the extraction chamber 2 is provided with a dispersion disk and stirring blades, the separation of flow phases of different densities can be achieved under high-speed rotation, so that the liquid is discharged from different liquid outlets on the extraction chamber 2 to achieve the separation and extraction of the flow.
