Description

An extraction pretreatment system and process Technical Field

[0001] This invention belongs to the field of extraction technology and relates to an extraction pretreatment system and process. Background Technology

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that separates a mixture by utilizing the different solubilities of its components in a solvent. Specifically, it utilizes the difference in solubility or partition coefficients of a substance in two immiscible (or slightly soluble) solvents to transfer the solute from one solvent to the other. It is widely used in chemical, metallurgical, and food industries, and is commonly used in the petroleum refining industry. The operation of separating the two immiscible liquids after extraction is called liquid-liquid extraction.

[0003] Currently, extraction technology is used in many industries, such as pharmaceuticals, chemicals, and food. In order to improve the extraction efficiency, solid materials are usually crushed before extraction to reduce the volume of solid materials and increase the total contact area between them and the extraction liquid. However, this means that the materials need to be introduced into crushing equipment first and then transferred to extraction equipment. This process involves many steps and results in low extraction efficiency.

The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention. The same or similar reference numerals in the drawings represent the same or similar parts.

A hinged door 3 at the bottom controls the opening and closing of the extraction tank 1. A support rod 4 is horizontally installed on the inner wall of the bottom of the extraction tank 1. A control mechanism for the opening and closing door 3 is located on the side of the extraction tank 1. The opening and closing door 3 has an L-shaped frame at its top and an L-shaped connecting frame at the bottom of the extraction tank 1, which are hinged together. A hydraulic cylinder is located on the side wall of the extraction tank 1, with its top hinged to the side wall and its piston rod hinged to the frame. Thus, the cylinder can open and close when it extends or retracts. Door 3 rotates to close or open the bottom of extraction tank 1. Simultaneously, a horizontally rotating reinforcing ring is installed at the bottom of extraction tank 1. A hydraulic cylinder is located between the outer end of the reinforcing ring and the outer wall of extraction tank 1, driving the reinforcing ring to rotate. The bottom of the reinforcing tube has an L-shaped reinforcing groove, and the free end of the door 3 has a reinforcing rod. When the door 3 is closed, the reinforcing rod engages in the reinforcing groove. After the hydraulic cylinder drives the reinforcing ring to rotate, the reinforcing groove drives the reinforcing rod upwards, resulting in a better seal between the door 3 and the bottom of extraction tank 1. Depending on the actual situation, a sealing ring can also be installed between the top of the door 3 and the bottom of extraction tank 1 to improve the sealing of the extraction process.

[0055] The rotating column 5 has a rectangular cross-section. The outer wall of the rotating column 5 is provided with a first cylindrical part 11 and a second cylindrical part 12. The first cylindrical part 11 is rotatably connected to the top of the extraction tank 1, and the second cylindrical part 12 is rotatably connected to the support rod 4.

[0056] A first driving mechanism is used to drive the rotating column 5 to rotate.

[0057] The first mating ring 13 and the second mating ring 14 are both provided with holes in the middle of the first mating ring 13 and the second mating ring 14 that mate with the rotating column 5.

[0061] A lifting part 22 is vertically and movably arranged on the top of the rotating column 5. The second transmission member 21 is located on the top of the lifting part 22. Two first limiting rails 23 are vertically arranged on the side wall of the extraction tank 1. The cross-section of the two first limiting rails 23 is L-shaped. A first adjusting member 24 is vertically and movably arranged between the two first limiting rails 23. A first linkage part 25 is horizontally arranged on the top of the first adjusting member 24. The lifting part 22 is rotatably connected to the free end of the first linkage part 25. The first adjusting member 24 can control the first transmission member 20 to engage or disengage with the second transmission member 21.

[0062] The extraction tank 1 has a protruding part 26 protruding outward on its side. A lifting screw 27 is vertically arranged inside the protruding part 26. The lifting screw 27 is rotatably connected to the top and bottom of the protruding part 26. The extraction cover 16 has a first linkage arm 28 and a second linkage arm 29 on its side. Both the first linkage arm 28 and the second linkage arm 29 are threadedly engaged with the lifting screw 27.

[0063] The second driving mechanism includes a support frame 30 disposed on the top of the extraction tank 1. A transmission rod 31 is horizontally rotatably disposed on the top of the support frame 30. A third transmission member 32 and a fourth transmission member 33 are respectively disposed at both ends of the transmission rod 31. Teeth are provided on the outer side of the third transmission member 32, the outer side of the fourth transmission member 33, and the top of the first transmission member 20. The third transmission member 32 and the top of the first transmission member 20 are engaged by the teeth.

[0064] The side wall of the extraction tank 1 is also vertically provided with two second limiting rails 34. The cross-section of each of the two second limiting rails 34 is L-shaped. A second adjusting member 35 is vertically and movably arranged between the two second limiting rails 34 (the raising and lowering of the first adjusting member 24 and the second adjusting member 35 can be manually adjusted and fixed in position by bolts or pins after adjustment; or it can be driven by a structure such as a hydraulic cylinder, pneumatic cylinder or electric actuator). A second linkage part 36 is horizontally arranged on the top of the second adjusting member 35, and an adjustment mechanism is vertically arranged on the second linkage part 36. The adjusting cylinder 37 is rotatably connected to the second linkage part 36, and the second linkage part 36 can drive the adjusting cylinder 37 to rise and fall.

[0065] The extraction cover 16 includes a top cover 16a, a bottom cover 16b, and several middle covers 16c. The diameters of the middle covers 16c vary. The heights of the top cover 16a, the middle covers 16c, and the bottom cover 16b decrease sequentially. The top cover 16a is a cover with its opening facing downwards, the bottom cover 16b is a cover with its opening facing upwards, and the middle covers 16c are annular. A first annular bend 40 is provided on the outer side of the bottom of the top cover 16a. The bottom cover 16b has an annular second bending ring 41 on the inner side of its top. The middle cover 16c has a third bending ring 42 on the inner side of its top and a fourth bending ring 43 on the outer side of its bottom. The first bending ring 40 and the third bending ring 42 located at the top can be engaged with each other. The second bending ring 41 and the fourth bending ring 43 located at the bottom can be engaged with each other. The third bending ring 42 located in the middle can be engaged with the adjacent fourth bending ring 43.

[0066] The lifting screw 27 includes a screw portion 27a and a smooth portion 27b located at the bottom of the screw portion 27a. When the first linkage arm 28 and the second linkage arm 29 are both threadedly connected to the screw portion 27a, the space inside the extraction hood 16 is at its maximum. When the second linkage arm 29 is located at the smooth portion 27b, the screw portion 27a can drive the first linkage arm 28 to descend, and the material inside the extraction hood 16 is squeezed by the top hood 16a, the middle hood 16c, and the bottom hood 16b.

[0067] The top of the top cover 16a has a fan-shaped feeding port. The shape of the feeding gate 17 matches the shape of the feeding port, and the feeding gate 17 is located below the feeding port. The inner end of the feeding gate 17 is provided with a rotating ring 44, which is rotatably connected to the first mating ring 13. The top of the feeding gate 17 is provided with an operating handle 45. When the crushing blade 15 is in the working state, the feeding gate 17 is in the closed state, and the first mating ring 13 acts on the rotating ring 44, causing the operating handle 45 to abut against the inner wall of one side of the feeding port.

[0068] The second mating ring 14 is rotatably connected to the bottom of the bottom cover 16b. The bottom of the bottom cover 16b is provided with a discharge port. One side of the discharge gate 18 is hinged to the discharge port. The outer side of the free end of the discharge gate 18 and the outer side of the bottom of the bottom cover 16b are both provided with protrusions. The protrusions of the discharge gate 18 and the protrusions on the bottom cover 16b are detachably connected by bolts.

[0069] There are two discharge doors 18, which are symmetrically distributed at the bottom of the bottom cover 16b.

[0070] The adjusting cylinder 37 is movably connected to the outer side of the support frame 30, and the outer wall of the adjusting cylinder 37 is movably attached to the support frame 30.

[0071] The present invention also provides a process for extraction using an extraction pretreatment system as described in any of the preceding claims, comprising the following steps:

[0072] S1, move the extraction hood 16 to the highest height, open the feeding door 17, and add the material to be extracted into the extraction hood 16 through the feeding port 2;

[0073] S2, close the feeding door 17, the second drive mechanism lowers the height of the extraction hood 16 and immerses the extraction hood 16 in the extraction liquid;

[0074] S3, stop moving the extraction hood 16, the first drive mechanism drives the rotating column 5 to rotate, and at the same time the crushing blade 15 crushes and stirs the material in the extraction hood 16;

[0075] S4, after extraction is complete, the valve on the pipe at the bottom of the door 3 is opened to drain the liquid in the extraction tank 1;

[0076] S5, the control mechanism opens the opening and closing door 3, the second drive mechanism drives the extraction hood 16 to move to the lowest height, and after opening the discharge door 18, the solid material in the extraction hood 16 is released.

[0077] The present invention provides an extraction pretreatment system. When extracting materials, the extraction chamber 16 is first moved to its highest height, and the feeding door 17 is opened. The material to be extracted is then added into the extraction chamber 16 through the feeding port 2. The feeding door 17 is closed, and the second drive mechanism lowers the height of the extraction chamber 16, immersing it in the extraction liquid. The movement of the extraction chamber 16 is stopped, and the first drive mechanism drives the rotating column 5 to rotate. Simultaneously, the crushing blade 15 crushes and stirs the material inside the extraction chamber 16. After extraction, the valve on the pipe at the bottom of the opening / closing door 3 is opened, discharging the liquid from the extraction tank 1. The control mechanism opens the opening / closing door 3, and the second drive mechanism drives the extraction chamber 16 to its lowest height. After opening the discharge door 18, the solid material inside the extraction chamber 16 is released.

[0078] In this way, the crushing and extraction of materials are carried out simultaneously, eliminating the need for separate equipment for crushing materials. This not only improves extraction efficiency but also reduces extraction costs.

[0079] In actual operation, the teeth on the second transmission member 21 are initially separated from those on the first transmission member 20, while the teeth on the fifth transmission member 39 and the fourth transmission member 33 are engaged. The power motor 19 then drives the lifting screw 27 to rotate via 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 adjusting cylinder 37, and the vertical rod 38. Simultaneously, the lifting screw 27 drives the first linkage arm 28 and the second linkage arm 29 to rise, thus allowing the extraction hood 16 to rise. At this point, the interior of the extraction hood 16 is in its maximum space state (the first bending ring 40 engages with the top third bending ring 42, the second bending ring 41 engages with the bottom fourth bending ring 43, and the middle third bending ring 42 engages with the adjacent fourth bending ring 43).

[0080] When the extraction hood 16 is raised to its maximum height, the worker opens the feeding door 17 through the operating handle 45 and adds the material into the extraction hood 16. Then, the operating handle 45 is turned to close the feeding port. Then, the power motor 19 rotates in the opposite direction to lower the height of the extraction hood 16, so that the extraction hood 16 moves to the middle position of the liquid.

[0081] Then, the height of the second adjusting member 35 is raised, and the second adjusting member 35 raises the second linkage part 36, the adjusting cylinder 37 and the fifth transmission member 39 in sequence, so that the fifth transmission member 39 is separated from the fourth transmission member 33; then the first adjusting member 24 is raised, which raises the lifting part 22 through the first linkage part 25, and makes the first transmission member 20 and the second transmission member 21 mesh through the teeth.

[0082] Then, the power motor 19 drives the second transmission component 21, the rotating column 5, the first mating ring 13, the second mating ring 14, and the crushing blade 15 to rotate through the first transmission component 20. The crushing blade 15 can crush and stir the material in the extraction hood 16, and at the same time accelerate the flow of liquid in the extraction hood 16 and the extraction tank 1. Secondly, since the outer surfaces of the first mating ring 13 and the second mating ring 14 are cylindrical, the extraction hood 16 is not affected at this time. At the same time, when the first mating ring 13 rotates, it acts on the rotating ring 44, which makes the operating handle 45 press more firmly against the inner wall of the feeding port, that is, it can prevent the feeding door 17 from opening automatically.

[0083] After extraction is complete and the liquid in extraction tank 1 is drained, the first adjusting member 24 is lowered and the second adjusting member 35 is raised. At this time, the crushing blade 15 stops rotating, while the first linkage arm 28 and the second linkage arm 29 both move downward. During the movement, the second linkage arm 29 moves to the smooth part 27b without external threads. At this time, the power motor 19 continues to drive the lead 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), while the top cover 16a moves downward. In this way, 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 and improving the utilization rate of the extract. Alternatively, if additional equipment is required for subsequent squeezing, the structure of this application can save the squeezing structure, which not only saves the process but also saves the production and use costs of the equipment.

[0084] After the extrusion is complete, the worker removes the protruding bolts on the discharge gate 18 from bottom to top. At this point, the discharge gate 18 can be opened directly, allowing the material inside the extraction hood 16 to fall out. After all the material inside the extraction hood 16 has fallen out, the discharge gate 18 is rotated upwards and then bolted to the bottom of the bottom hood 16b.

[0085] Then the power motor 19 rotates in the opposite direction, raising the first linkage arm 28. The first linkage arm 28 raises the top cover 16a. The top cover 16a, through the first bending ring 40, the third bending ring 42 and the fourth bending ring 43, can lift the bottom cover 16b upwards, and cause the second linkage arm 29 to move from the smooth part 27b to the lead screw part 27a. At this time, the extraction cover 16 returns to its shape and can be raised to the highest point for the next extraction.
