Problems solved by technology

Apparently, a drum with a cylindrical structure cannot produce such an effect
[0012] 3. The material enters the drum from the shell space, relying on the self-priming effect produced by the drum and the impeller at the bottom of the shell, while the self-priming effect produced by the cylindrical structure is poor

Embodiment Construction

[0029] see figure 1 , a rotating drum 4 with blades 5 is arranged in the cylindrical housing 2, and each feed pipe and discharge pipe are respectively arranged on the side of the cylindrical housing 2, and the rotating drum 4 is set as a conical frustum body with a taper, and the conical frustum The body has a small lower bottom and a large upper bottom, and the size of the taper is properly set according to the density difference between the light and heavy phases. If the density difference is large, the taper can be appropriately smaller;

[0030] In order to ensure the synchronous rotation of the material and the drum, the blade 5 is set to have a taper that matches the drum 4, and the output shaft of the drive motor 8 is directly connected to the central shaft of the drum 4 with a coupling 9 to realize the drive motor. The direct drive form of the drum avoids problems such as wear and pollution caused by the belt drive.

[0031] The light and heavy phase materials are res...

Abstract

A conical barrate centrifugal extractor is provided with a barrate with blades in a cylindrical casing, each charging tube and discharging tube is arranged on a lateral part of the cylindrical casing separately, is characterized in that the barrate is a round bench body with conicity, and the round bench body has a small lower bottom and a large upper bottom. By means of using the conical barrate, it is capable of increasing the material detention period in the barrate without alteration of the barrate height, so that the material may be mixed and transferred with mass perfectly. The barrate is capable of generating different centrifugal forces in the height direction, and further meets the requirement of an extraction process.

Description

technical field [0001] The invention relates to industrial equipment used in the fields of chemical industry, petrochemical, pharmaceutical, traditional Chinese medicine extraction, biology, hydrometallurgy, cosmetics, etc., more specifically an extraction equipment. Background technique [0002] The operation of extracting a certain component from a liquid mixture with a solvent is called liquid / liquid extraction or solvent extraction. The extraction operation includes two processes: one is that the raw material liquid and the extractant are fully mixed and contacted to complete the mixed mass transfer process; the second is that the material after the mixed mass transfer will form light and heavy phases under the action of centrifugal force due to the difference in density , to achieve the purpose of separation and complete the separation process. The centrifugal extractor is a kind of equipment that realizes the above functions. The drums of centrifugal extractors in th...
