Specifically, the pair of rollers includes two extruding rollers 11 and two roll shafts which are transversely arranged in parallel, each roll shaft penetrates through one extruding roller 11, and the extruding rollers 11 and the roll shafts are relatively fixed and coaxial. The roll shafts are rotatably connected to the inner wall of the extrusion tank 3, for example, both ends of each roll shaft are fixed on the inner side wall of the extrusion tank 3 by matching with the bearing 20 seats, so that the roll shafts can drive the extrusion rollers 11 to rotate when rotating.
The first driving member includes two driving sources 10, and the driving sources 10 may be motors, so that the two driving sources 10 are fixed on the outer side wall of the extrusion tube, and a motor shaft of each driving source 10 and one of the roller shafts may be in transmission connection through a shaft coupling, so that the two driving sources 10 are used for driving the two roller shafts to rotate in opposite directions, that is, the two roller shafts are driven by the driving sources to rotate in opposite directions, thereby enabling the two extrusion rollers 11 to rotate in opposite directions. For example, a roller clockwise rotation of a driving source 10 drive to this roller drives one and to crowded roller 11 clockwise rotation, and another driving source 10 drives another roller anticlockwise rotation, thereby this roller drives another and to crowded roller 11 anticlockwise rotation, and two are crowded roller 11 mutual antiport and can produce the extrusion and pile up kibbling effect like this, can carry out the crushing to crowded with solid-state raw materials.
In some embodiments, the crushing member may be an impeller as long as it can crush the solid raw material.
Because the raw materials can form the residue after smashing and leaching many times, consequently still need take out these residues aggregations, for this reason, in this embodiment, can dismantle in the leaching jar 2 and be provided with filter, filter be used for to the material that second pipeline 9 sent is filtered to intercept solid-state raw materials in the material, then take out filter and can collect the residue, reassemble this filter in leaching jar 2 before using again next time. When the solid raw material can be leached, the filter element can not filter the material sent by the second conveying pipeline 9.
Specifically, with reference to fig. 4 to 6, the filter element comprises a filter cartridge 17, a cartridge cover 18 and a cannula 21; the filter cylinder 17 is in a circular cylindrical shape, the first end and the second end of the filter cylinder are both in a closed state, a plurality of uniformly distributed sieve holes are formed in the filter cylinder 17, and the cylinder cover 18 is detachably arranged at the second end of the filter cylinder 17 in a covering mode; the outlet end of the second delivery duct 9 extends from the first end of the filter cartridge 17 into the filter cartridge 17 and is spaced from the cartridge cover 18; the insertion tube 21 is slidably disposed through the cylinder cover 18, and two ends of the insertion tube 21 are respectively located at two sides of the cylinder cover 18, so that the insertion tube 21 can be abutted to or separated from the outlet end of the second conveying pipeline 9.
Therefore, when repeated crushing and leaching are needed, the insertion pipe 21 is only required to slide towards the direction close to the outlet end of the second conveying pipeline 9, so that the insertion pipe 21 is in butt joint with the outlet end of the second conveying pipeline 9, the insertion pipe 21 plays a role in prolonging the second conveying pipeline 9, the materials in the second conveying pipeline 9 can be directly discharged into the leaching tank 2 through the insertion pipe 21 without being discharged into the filter cartridge 17, and further heating leaching is realized; when filtration is needed, the insertion pipe 21 only needs to slide towards the direction far away from the outlet end of the second conveying pipeline 9, so that the insertion pipe 21 is separated from the outlet end of the second conveying pipeline 9, materials in the second conveying pipeline 9 can enter the filter cylinder 17, filtration is achieved based on the sieve holes of the filter cylinder 17, residues are left, and the solvent is discharged from the sieve holes.
The connection between the cover 18 and the filter cartridge 17 can be achieved by screwing, and of course, can be achieved by screw connection, etc., as long as the connection can be disassembled,
because the solid raw material needs to be taken out from the mixed liquid in a filtering mode after leaching, but because the raw material has certain adsorbability and usually absorbs some solvent components, the raw material needs to be cleaned subsequently, the cleaning is generally to wash the filtered raw material by using clean water, and in the prior art, the material needs to be taken out from the leaching tank and then washed, and certain processing time needs to be consumed.

Specifically, the first end of the filter cartridge 17 is provided with a central hole, and the bearing 20 is embedded in the central hole, so that the second conveying pipeline 9 passes through the bearing 20 to enable the outlet end of the second conveying pipeline to extend into the filter cartridge 17, and the bearing 20 is used for realizing the rotatable matching of the second conveying pipeline 9 and the filter cartridge 17, and ensuring the smoothness and the smoothness of the rotation of the two. Of course, in some embodiments, the filter cartridge 17 may also be fixed with respect to the second conveying duct 9, also enabling a filtering action.
In this embodiment, a plurality of vane plates 19 are disposed on the outer periphery of the filter cartridge 17, and the liquid outlet path of the first filling pipe 4 passes through at least one of the vane plates 19, so that the liquid flowing out of the first filling pipe 4 can push at least one of the vane plates 19, and thus the plurality of vane plates 19 can increase the impact force of the liquid introduced from the first filling pipe 4 on the filter cartridge 17, increase the rotation speed of the filter cartridge 17, and improve the flushing effect, and at the same time, the vanes are disposed to intercept the liquid, so that more liquid can enter the filter cartridge 17.
In this embodiment, since the first adding pipe 4 is disposed on the top of the leaching tank 2, in order to utilize the energy of the falling liquid as much as possible, the filter cartridge 17 is horizontally disposed, the outlet end of the second delivery pipe 9 transversely extends into the filter cartridge 17, and the outlet end of the first adding pipe 4 is located above the filter cartridge 17.
To sum up, the utility model discloses leach device sends the material of deposit in leaching tank 2 bottoms to extrusion jar 3 in through first pipeline and carries out crushing to crowded to make the absorption liquid of solid-state raw materials more ooze in the material, and smash solid-state raw materials for more tiny powdered, from this when the powdered material after smashing sends back to leaching tank 2 in through second pipeline 9, can more fully contact with the solvent, improve and leach the effect.
