Description

Technical Field

[0001] The invention belongs to the technical field of extraction and relates to an extraction pre-treatment system and process. Background Art

[0002] Extraction, also known as solvent extraction, liquid-liquid extraction, or extraction, is a unit operation that separates a mixture by exploiting the different solubilities of the components in the solvent. Specifically, it exploits the differences in solubility or partition coefficient between two immiscible (or slightly soluble) solvents to transfer a solute from one solvent to another. It is widely used in the chemical, metallurgical, and food industries, and is also commonly used in the petroleum refining industry. Separating the two immiscible liquids after extraction is called separation.

[0003] At present, extraction technology is used in many industries, such as medicine, chemical industry, food and other fields.

[0070] The present invention also provides a process for extraction using an extraction pretreatment system as described in any one of the above items, comprising the following steps:

[0071] S1, move the extraction cover 16 to the highest height, open the feeding door 17, and add the material to be extracted into the extraction cover 16 through the feeding port 2;

[0072] S2, closing the feeding door 17, and the second driving mechanism lowering the height of the extraction cover 16 so that the extraction cover 16 is immersed in the extraction liquid;

[0073] S3, the extraction cover 16 stops moving, the first driving mechanism drives the rotating column 5 to rotate, and the crushing knife 15 crushes and stirs the material in the extraction cover 16;

[0074] S4, after the extraction is completed, the valve on the pipe at the bottom of the opening and closing door 3 is opened to discharge the liquid in the extraction tank 1;

[0075] S5, the control mechanism opens the opening and closing door 3, the second driving mechanism drives the extraction cover 16 to move to the lowest height, and the discharge door 18 is opened to discharge the solid material in the extraction cover 16.

[0076] The present invention provides an extraction pretreatment system. When extracting a material, the extraction cover 16 is first moved to the highest height, and after opening the feeding door 17, the material to be extracted is added to the extraction cover 16 through the feeding port 2; the feeding door 17 is closed, and the second driving mechanism lowers the height of the extraction cover 16 and immerses the extraction cover 16 in the extraction liquid; the movement of the extraction cover 16 is stopped, and the first driving mechanism drives the rotating column 5 to rotate, and at the same time the crushing knife 15 crushes and stirs the material in the extraction cover 16; after the extraction is completed, the valve on the pipeline at the bottom of the opening and closing door 3 is opened to discharge the liquid in the extraction tank 1; the control mechanism opens the opening and closing door 3, and the second driving mechanism drives the extraction cover 16 to the lowest height, and after opening the discharge door 18, the solid material in the extraction cover 16 is discharged.

[0077] In this way, the crushing and extraction of the material are carried out simultaneously, and there is no need to use separate equipment to crush the material. This not only improves the extraction efficiency, but also reduces the cost of extraction.

[0078] During actual operation, first, the teeth on the second transmission member 21 and the teeth on the first transmission member 20 are in a separated state, and the teeth on the fifth transmission member 39 and the fourth transmission member 33 are in a meshing state; in this way, the power motor 19 drives the lifting screw 27 to rotate through the first transmission member 20, the third transmission member 32, the transmission rod 31, the fourth transmission member 33, the fifth transmission member 39, the adjustment cylinder 37, and the vertical rod 38, and at the same time, the lifting screw 27 drives the first linkage arm 28 and the second linkage arm 29 to rise, so that the extraction cover 16 can be raised, and at this time, the interior of the extraction cover 16 is in a state of maximum space (the first bending circle 40 and the third bending circle 42 at the top are interlocked with each other, the second bending circle 41 and the fourth bending circle 43 at the bottom are interlocked with each other, and the third bending circle 42 in the middle is interlocked with the adjacent fourth bending circle 43);

[0079] When the extraction cover 16 is raised to its highest height, the worker opens the feeding door 17 by operating the handle 45 and adds the material into the extraction cover 16. Then, the operating handle 45 is turned to close the feeding port. The power motor 19 then rotates in the reverse direction to lower the height of the extraction cover 16, so that the extraction cover 16 moves to the middle of the liquid.

[0080] The second adjusting member 35 is then raised, which in turn raises the second linkage portion 36, the adjusting cylinder 37, and the fifth transmission member 39, separating the fifth transmission member 39 from the fourth transmission member 33. The first adjusting member 24 is then raised, raising the lifting portion 22 via the first linkage portion 25, and causing the first transmission member 20 to engage with the second transmission member 21 through the teeth.

[0081] Afterwards, the power motor 19 drives the second transmission member 21, the rotating column 5, the first matching ring 13, the second matching ring 14 and the crushing knife 15 to rotate through the first transmission member 20. The crushing knife 15 can crush and stir the material in the extraction cover 16, and at the same time accelerate the flow of the liquid in the extraction cover 16 and the extraction tank 1; secondly, since the exterior of the first matching ring 13 and the second matching ring 14 is cylindrical, the extraction cover 16 can be unaffected at this time; at the same time, when the first matching ring 13 rotates, it acts on the rotating ring 44, so that the operating handle 45 has the effect of being more tightly pressed against the inner wall of the feeding port, that is, it can prevent the feeding door 17 from opening automatically.

[0082] When the extraction is completed and the liquid in the extraction tank 1 is emptied, the first adjusting member 24 is lowered and the second adjusting member 35 is raised. At this time, the crushing knife 15 no longer rotates, and the first linkage arm 28 and the second linkage arm 29 both move downward; during the movement, the second linkage arm 29 will move to the smooth part 27b without external threads. At this time, the power motor 19 continues to drive the screw part 27a to rotate and drive the first linkage arm 28 downward. At this time, the height of the bottom cover 16b no longer decreases (supported by the support rod 4), and the top cover 16a moves downward, so that the top cover 16a, the middle cover 16c and the bottom cover 16b can squeeze the material in the extraction cover 16, thereby squeezing out the liquid in the solid material, thereby improving the utilization rate of the extraction liquid; or if additional equipment is required for squeezing later, the structure of the present application can save the extrusion structure, which not only saves the process, but also saves the production and use costs of the equipment.

[0083] After the extrusion is completed, the worker removes the raised bolts on the discharge door 18 from the bottom up. At this time, the discharge door 18 can be opened directly to let the material in the extraction cover 16 fall out. After the material in the extraction cover 16 falls out, the discharge door 18 is rotated upward and fixedly connected to the bottom of the bottom cover 16b with bolts.

[0084] Afterwards, the power motor 19 rotates in the opposite direction to raise the first linkage arm 28. The first linkage arm 28 raises the top cover body 16a. The top cover body 16a can pull up the bottom cover body 16b through the first bending circle 40, the third bending circle 42 and the fourth bending circle 43, and make the second linkage arm 29 move from the smooth part 27b to the screw part 27a. At this time, the extraction cover body 16 restores its shape and can be raised to the highest point for the next extraction.

[0085] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
