For different kinds of materials, different devices need to be used for extraction, which has poor process flexibility and high investment cost. In addition, product quality and extraction rate cannot be effectively considered. SUMMARY

[0003] The utility model discloses a percolation extraction equipment, which can realize various extraction processes and is suitable for different kinds and forms of materials.

[0004] To achieve this purpose, the utility model adopts the following technical scheme:

[0009] The third pipe group comprises a plurality of parallel third input pipes, and the third input pipes are communicated with the top inlets one by one in a one-to-one correspondence with the percolation columns.

[0010] Preferably, the percolation column is provided with two, which are a first percolation column and a second percolation column;

[0011] The first percolation column has a first bottom inlet, a first bottom outlet, a first top outlet and a first top inlet, the second percolation column has a second bottom inlet, a second bottom outlet, a second top outlet and a second top inlet, the first bottom inlet, the first top inlet and the second top inlet are used for flowing solvent, the second bottom inlet is used for flowing the solvent or extract, and the first bottom outlet, the first top outlet, the second bottom outlet and the second top outlet are used for flowing the extract.

[0012] The second input pipe and the third input pipe are both provided with two, two second input pipes are respectively communicated with the first bottom inlet and the second bottom inlet, and two third input pipes are respectively communicated with the first top inlet and the second top inlet.

[0017] The utility model discloses the beneficial effect lies in:

[0018] The percolation extraction device provided by this utility model includes at least two percolation columns, a first tube group, a second tube group, and a third tube group. Since the first connecting tube connects the percolation columns in series, and its two ends are respectively connected to the top outlet and the bottom inlet, the first tube group combines at least two percolation columns into a series structure. In this case, the solvent can enter the first percolation column through the bottom inlet, and the extract in the first percolation column will flow into the next percolation column through the first connecting tube and the bottom inlet for secondary extraction, and exit from the top outlet of that percolation column. This cycle repeats, with repeated extraction in all percolation columns, thereby achieving series dynamic extraction. Because several parallel second input tubes connect to the percolation column... Each percolation column is connected to the bottom inlet in a corresponding manner. Therefore, the second tube assembly combines at least two percolation columns into a parallel structure. At this time, the solvent can enter all percolation columns through several second input tubes. After extraction, the extract flows out from the top outlet of each percolation column, thus realizing parallel countercurrent dynamic extraction. Since several parallel third input tubes are connected to the top inlet of each percolation column in a corresponding manner, the third tube assembly combines at least two percolation columns into a parallel structure. At this time, the solvent can enter all percolation columns through several third input tubes. The solvent entering the percolation column can soak or spray the material from top to bottom, thus realizing parallel soaking extraction or parallel cocurrent dynamic extraction.

[0019] This percolation extraction equipment can connect at least two percolation columns through a first tube group, a second tube group, and a third tube group, enabling the at least two percolation columns to perform multiple extraction processes. This makes it suitable for materials of different types and forms, and allows for refined management during the extraction process, reducing costs and providing strong process flexibility.

The second injection tube 22 is connected to the solvent storage tank. Both second input tubes 21 are equipped with a delivery pump and a valve, which can flexibly adjust the liquid inlet of the two second input tubes 21 according to the distribution of the material in the first percolation column 4 and the second percolation column 5.
