Problems solved by technology

1) The installation height or unit ground weight is not enough, and the vertical extraction tank cannot be used
2) During the original extraction process, the loss of active ingredients in the slag was felt to be large, or in order to increase the yield, the amount of solvent used and the number of extractions had to be increased; 3) The door of the traditional vertical extraction tank is not safe, and it is easy to leak ;4) I want to use basket extraction, but I feel that the supporting conveying and cleaning system is too bulky; 5) I used to use chain row and drum type intermittent countercurrent extraction, and I feel that the extraction efficiency is low; 6) I use spiral continuous countercurrent equipment, but often Blocking materials or materials not suitable for extrusion
However, there are still many problems in the extraction methods of these two methods. The extraction method of the chain row countercurrent has the problems of small flow, small processing capacity, and low work efficiency.
In addition, although the auger countercurrent extraction method can carry out large flow and high pressure extraction, it has poor adaptability to the types of logistics

[0050] Manipulator 12 of the present invention is existing structure, and as preferred scheme, Figure 9 As shown, this embodiment provides one of the manipulator structures. The clamping and rotating manipulator includes a connected clamping part 121 and a rotating part 122. The clamping part 121 is used to clamp the medicine basket 123, and the rotating part 122 is used to drive the medicine basket. 123 flips. In the specific use process, the clamping action for the medicine basket 123 is completed by the clamping member 121, and then the rotating member 122 drives the clamping member 121 to rotate, generally the medicine basket 123 is rotated 180°, so that the medicine basket 123 The opening of the medicine basket is downward, so that the medicine dregs can be completely separated from the medicine basket 123, and the medicine basket 123 is placed in a reversed state, so that the subsequent cleaning process will become easier. The clamping and rotating manipulator can pref...

Description

technical field [0001] The invention relates to an extraction device, in particular, it provides a rotating basket continuous countercurrent extraction device. Background technique [0002] Basket extraction is to put the raw materials of Chinese herbal medicines into several medicine baskets, put them into the decoction tank in layers, and the medicine baskets and medicinal materials are completely immersed in the extraction solvent. In the heating state, the extraction liquid circulates from the side of the decoction tank into the tank through the circulation pump, and enters the basket through the special small hole of the medicine basket to make micro-motion with the medicinal materials, and the active ingredients in the medicinal materials are taken out and dissolved into the extraction solvent inside. [0003] Countercurrent extraction means that during the extraction process, the material and the solvent move continuously at the same time, but in opposite directions....
