Forced reflux extraction tank and forced reflux extraction process

Abstract

The invention discloses a forced reflux extraction tank, which comprises a tank body, wherein a grate is arranged on the bottom part in the tank body; the tank body is provided with a cyclone system; the cyclone system comprises a fluid suction port, a pump and a cyclone which are connected through a pipeline; the fluid suction port is arranged on the upper part in the tank body; the cyclone comprises a main cyclone tube and sub cyclone tubes connected onto the main cyclone tube; the main cyclone tube is in an arc shape; one end of each sub cyclone tube is connected with the inner side of the arc shape, and the other end of each sub cyclone tube is provided with an opening; and the sub cyclone tube are inclined towards the opening direction of the main cyclone tube. According to the reflux extraction tank, the cyclone system is adopted, the trash pump is used for sucking liquid medicine on the top part in the tank body from the fluid suction port and pumping into the cyclone, and then the liquid medicine is respectively sprayed out through the main cyclone tube and the sub cyclone tubes, so that medicinal materials deposited on the grate is rotated and turned accordingly, the accumulation of the medicinal materials is effectively avoided, the mixing of the medicinal materials is more uniform, and the heating is also more uniform.

Description

technical field [0001] The invention relates to the field of medicinal material extraction, in particular to an extraction tank and a forced reflux extraction process. Background technique [0002] Commonly used extraction tanks generally put the medicine into the extraction tank when extracting the medicine, and then soak and heat it. There is a filtering grate at the bottom of the extraction tank, and there is a liquid outlet and a spare liquid outlet at the bottom of the tank. The heated and soaked medicinal liquid flows out from the liquid outlet and enters the next process. However, because the dregs of the medicine will settle naturally, it is easy to block the grate, which greatly affects the normal production, and the cleaning is also very troublesome. Such a process cannot meet the requirements of mass production. Contents of the invention [0003] The object of the present invention is to provide a forced reflux extraction tank and a forced reflux extraction pr...
