[0019] The present invention provides an efficient petrochemical extraction device through improvements, which has the following improvements and advantages compared with the prior art:

[0020] First, when the rotating tube of the present invention rotates, the centrifugal force can cause the swing arm with the weighted ball end to swing upward.

[0021] Secondly, when the rotating tube rotates, the present invention can drive the sloped ring cylinder on the outer peripheral wall to rotate synchronously. When the sloped ring cylinder rotates, it can resist the ball head rod on the side arm frame. In conjunction with the subsequent return spring, the side arm frame can reciprocate in the vertical direction, and drive the short rod and the liquid diverter plate on the short rod to move synchronously, thereby achieving vibration of the raw material and the extractant, promoting mixing between the raw material and the extractant, and achieving the purpose of improving the extraction efficiency.

[0022] Thirdly, the rotating plate provided in the present invention can rotate together with the rotating tube, and cooperates with the provided corrugated sheet to promote mixing between materials. After the extraction and stirring are completed, the driving motor can be turned off. At this time, the swing arm with the counterweight ball end moves downward, and the multiple movable swing plates are retracted. At the same time, the side arm frame stops moving up and down due to the loss of the resistance of the slope ring cylinder. At this time, the closed movable swing plates and the stopped liquid diverter plate can stabilize the flow of the stirred materials, thereby promoting the rapid stabilization of the materials and accelerating the stratification rate of the materials.

[0023] Fourthly, when the inner end rod of the present invention rotates, it can drive the triangular cavity block and the auger blade to rotate. The rapidly rotating triangular cavity block cooperates with the through hole to form a throwing and mixing process for the raw material and the extractant in the initial stage of feeding. At the same time, when the material flows downward along the auger blade, it can also produce a mixing effect on the material, so as to achieve the purpose of improving the extraction efficiency of the device.

[0037] The present invention provides an efficient petrochemical extraction device through improvement. The technical solution of the present invention is:

[0038] like Figures 1 to 9 As shown, an embodiment of the present invention provides an efficient petrochemical extraction device, comprising an extraction tank 1, a base 102 being provided at the bottom end of the extraction tank 1, and a support member being provided between the base 102 and the extraction tank 1, the support member being able to cooperate with the base 102 to ensure the structural stability of the extraction tank 1, and further comprising a feeding assembly, a mixing assembly, and an oscillating assembly;

[0039] The feeding assembly includes a rotating tube 12 rotatably mounted on the extraction tank 1, and the top of the rotating tube 12 is rotatably connected to the top tube 10, a pair of fixed support rods 20 are fixed between the outer peripheral wall of the top tube 10 and the extraction tank 1, and an inner end rod 5 is rotatably mounted between the rotating tube 12 and the top tube 10. A driving unit is installed on the side of the top of the extraction tank 1 close to the rotating tube 12, and multiple feeding ports are opened at the position of the outer peripheral wall of the rotating tube 12 close to the bottom end, and a one-way liquid outlet valve 121 is fixedly installed in each feeding port; during extraction, raw materials and extractants can be added to the rotating tube 12. At the same time, when the rotating tube 12 rotates, the raw materials and extractants are evenly added to the extraction tank 1 through the feeding port and the one-way liquid outlet valve 121. During the feeding process, the extractant and the raw materials are preliminarily mixed.

[0040] The mixing assembly includes a plurality of swing arms 13 rotatably connected to the outer peripheral wall of the rotating tube 12 by a movable shaft, and a counterweight ball end 131 is fixed to the end of each swing arm 13. A group of movable swing plates 132 are rotatably connected to the outer peripheral wall of the rotating tube 12 near the swing arm 13 by a movable shaft, and each group of movable swing plates 132 and the swing arm 13 are provided with a frame bar 133. The swing arm 13 and the movable swing plate 132 are fixedly installed with a limiting protrusion at the position near the frame bar 133, and the limiting protrusion is slidably connected to the inner wall of the frame bar 133; when the rotating tube 12 rotates, the swing arm 13 with the counterweight ball end 131 can be swung upward under the action of centrifugal force. At the same time, when the swing arm 13 is raised, the frame bar 133 can be used to drive the multiple movable swing plates 132 to be raised in sequence, thereby effectively expanding the stirring range of the mixing assembly. In actual use, the centrifugal force generated by the swing arm 13 can be changed by adjusting the speed of the subsequent driving motor 9 to achieve the purpose of changing the stirring range of the mixing assembly.

[0041] The oscillation assembly includes two side arms 14, and the tops of the two side arms 14 are fixedly mounted with piston rods 301 and ball rods 17. The end of the outer peripheral wall of the rotating tube 12 near the top is fixed with a sloped ring cylinder 19. The ball rod 17 contacts the bottom side of the sloped ring cylinder 19. The piston rod 301 and the ball rod 17 are both slidably connected to the top of the extraction tank 1. The bottom ends of the two side arms 14 are fixed with short rods 152, and each short rod 152 is fixed with multiple liquid dipping discs 15, and each liquid dipping disc 15 is provided with multiple turbulence holes 151. The above structure can drive the sloped ring cylinder 19 on the outer peripheral wall to rotate synchronously when the rotating tube 12 rotates. When the sloped ring cylinder 19 rotates, it can resist the ball head rod 17 on the side arm 14. In conjunction with the subsequent return spring 302, the side arm 14 can be made to reciprocate in the vertical direction, and drive the short rod 152 and the liquid diverter 15 on the short rod 152 to move synchronously, thereby achieving oscillation of the raw material and the extractant, promoting mixing between the raw material and the extractant, and achieving the purpose of improving the extraction efficiency.

[0042] As a further solution of the present invention, in order to make the rotating tube 12 and the inner end rod 5 rotate towards each other, the present application provides a driving unit, which includes a driving motor 9 fixedly mounted on the top of the extraction tank 1, and the output shaft of the driving motor 9 is fixedly mounted with a driving conical tooth 91, the end of the inner end rod 5 near the top is fixed with a driven conical tooth 1 4, and the outer peripheral wall of the end of the rotating tube 12 near the top is fixed with a driven conical tooth 2 18, and the driven conical tooth 1 4 and the driven conical tooth 2 18 are engaged with the driving conical tooth 91; when the device is in operation, the driving motor 9 can be controlled to start, and through the transmission action of the driving conical tooth 91, the driven conical tooth 1 4 and the driven conical tooth 2 18, the rotating tube 12 and the inner end rod 5 can be rotated towards each other, and when the inner end rod 5 rotates, pre-mixing treatment can be performed.

[0043] Furthermore, in order to facilitate the addition of materials, the outer peripheral wall of the top tube 10 is fixedly connected on both sides with a feed pipe 2 and a feed pipe 2 201 which are arranged in an interlaced manner, and the other ends of the feed pipe 1 2 and the feed pipe 2 201 are respectively connected to an external raw material supply system and an extractant supply system; when the device is in use, materials can be added to the top tube 10 and the rotating tube 12 through the external raw material supply system and the extractant supply system, and through the feed pipe 1 2 and the feed pipe 2 201.

[0044] As a further solution of the present invention, in order to mix the materials when adding, a plurality of equally distributed triangular cavity blocks 501 are fixed to one end of the inner end rod 5 close to the top tube 10, and a plurality of equally distributed through holes 502 are opened on the triangular cavity blocks 501, and an auger blade 503 is fixed on the outer peripheral wall of the inner end rod 5; when the inner end rod 5 rotates, it can drive the triangular cavity block 501 and the auger blade 503 to rotate, and the rapidly rotating triangular cavity block 501 cooperates with the through holes 502 to form a throwing and mixing treatment for the raw material and the extractant in the initial stage of adding. At the same time, when the material flows downward along the auger blade 503, it can also produce a mixing effect on the material, so as to achieve the purpose of improving the extraction efficiency of the device.

[0045] Furthermore, guide cylinders 3 that slide with the piston rod 301 are fixedly installed on both sides of the top of the extraction tank 1, and return springs 302 are fixed between the guide cylinder 3 and the piston rod 301; the guide cylinder 3, the piston rod 301 and the return spring 302 cooperate with each other, and can cooperate with the slope ring cylinder 19 and the ball head rod 17 to promote the side arm frame 14 to perform stable reciprocating motion in the vertical direction.

[0046] As a further solution of the present invention, a partition 11 is fixed at one end of the interior of the extraction tank 1, a rotating tube 12 is rotatably connected to the partition 11, two side arms 14 are slidably connected to the partition 11, and the support member includes a plurality of legs 104 fixed on the base 102, and the top ends of the plurality of legs 104 are commonly fixed with an outer ring frame 101, and the outer ring frame 101 is fixedly connected to the outer peripheral wall of the extraction tank 1; the provided legs 104 and outer ring frame 101 can ensure the stability of the structure between the base 102 and the extraction tank 1.

[0047] Furthermore, in order to quickly release the lower layer of liquid after the extraction operation is completed, the bottom end of the extraction tank 1 is fixedly connected to a valved drain pipe 103, and a transparent observation window 105 is fixedly provided on one side of the extraction tank 1; the transparent observation window 105 is convenient for observing the extraction status inside the extraction tank 1 and the stratification position of subsequent materials, thereby playing an auxiliary role in the extraction of the upper layer of liquid.

[0048] Furthermore, a rotating plate 16 is fixed to the bottom end of the rotating tube 12, and corrugated sheets 161 are fixed to the outer walls on both sides of the rotating plate 16; the rotating plate 16 is capable of rotating together with the rotating tube 12, and the corrugated sheets 161 are coordinated to promote mixing between materials; and after the extraction and stirring are completed, the driving motor 9 can be turned off. At this time, the swing arm 13 with the counterweight ball end 131 moves downward, and the multiple movable swing plates 132 are retracted. At the same time, the side arm frame 14 stops moving up and down due to the loss of the resistance of the slope ring cylinder 19; at this time, the closed movable swing plate 132 and the stopped liquid dipping plate 15 can stabilize the flow of the stirred material, so as to promote the material to quickly stabilize and accelerate the stratification rate of the material.

[0049] As a further solution of the present invention, a liquid extraction pipe 6 is slidably connected to one side of the top of the extraction tank 1 in the vertical direction. The liquid extraction pipe 6 has a U-shaped structure as a whole. A rack 601 is fixed on the side wall of one end of the liquid extraction pipe 6. A side frame 7 is fixed on one side of the outer peripheral wall of the extraction tank 1, and an arc-shaped limiting hoop 701 is fixed on the side frame 7. The liquid extraction pipe 6 is slidably connected to the arc-shaped limiting hoop 701. A self-locking servo motor 702 is fixed to the inner wall of one side of the side frame 7, and the output shaft of the self-locking servo motor 702 is fixedly installed with a driving gear 703 that meshes with the rack 601. After the lower layer of liquid is discharged through the valved discharge pipe 103, the provided self-locking servo motor 702 can be used to drive the driving gear 703 to rotate, and through the transmission action of the rack 601, the liquid extraction pipe 6 is driven to adjust in the vertical direction. When the bottom end of the liquid extraction pipe 6 is placed in the upper layer of liquid, the self-locking servo motor 702 stops running and uses its own position ring to lock to lock the position of the liquid extraction pipe 6.

[0050] Furthermore, a liquid pump 8 is fixedly installed on one side of the top outer wall of the base 102, and the output end of the liquid pump 8 is fixedly connected to an output pipe 801. In order to avoid interference between the liquid pump 6 and the liquid pump 8 when the liquid pump 6 moves up and down, a corrugated hose 602 is fixedly connected between the input end of the liquid pump 8 and the liquid pump 6; when the set liquid pump 8 is in operation, it can cooperate with the set liquid pump 6 and the corrugated hose 602 to extract the upper liquid in the extraction tank 1.

[0051] The specific working method is as follows: when in use, the raw material supply system and the extractant supply system are connected, and the material is added into the top tube 10 and the rotating tube 12 through the feed pipe 1 2 and the feed pipe 2 201, the drive motor 9 is controlled to start, and the driving conical gear 91 and the driven conical gear 1 4 and the driven conical gear 2 18 are driven to drive the rotating tube 12 and the inner end rod 5 to rotate in opposite directions. When the inner end rod 5 rotates, the triangular cavity block 501 and the auger blade 503 are driven to rotate. The rapidly rotating triangular cavity block 501 cooperates with the through hole 502. In the initial stage of feeding, the raw material and the extractant are scattered and mixed. At the same time, when the material flows downward along the auger blade 503, the material is also mixed, so as to achieve the purpose of improving the extraction efficiency of the device. At the same time, when the rotating tube 12 rotates, the raw material and the extractant are evenly added into the extraction tank 1 through the feeding port and the one-way liquid outlet valve 121. During the feeding process, the extractant and the raw material are preliminarily mixed.

[0052] When the rotating tube 12 is rotating, under the action of centrifugal force, the swing arm 13 with the counterweight ball end 131 swings upward. At the same time, during the lifting process of the swing arm 13, the frame bar 133 drives the multiple movable swing plates 132 to lift up in sequence, thereby effectively expanding the stirring range of the mixing assembly. In actual use, the centrifugal force generated by the swing arm 13 can be changed by adjusting the speed of the subsequent drive motor 9 to achieve the purpose of changing the stirring range of the mixing assembly; when the rotating tube 12 rotates, the sloped ring cylinder 19 on the outer peripheral wall is driven to rotate synchronously. When the sloped ring cylinder 19 rotates, it contacts the ball head rod 17 on the side arm frame 14, and cooperates with the subsequent return spring 302 to make the side arm frame 14 reciprocate in the vertical direction, and drive the short rod 152 and the short rod 152 to rotate. The liquid-dipping disc 15 on the rod 152 moves synchronously, thereby achieving oscillation of the raw material and the extractant, thereby promoting mixing between the raw material and the extractant, and achieving the purpose of improving the extraction efficiency; the rotating plate 16 is provided, and rotates together with the rotating tube 12, and cooperates with the wavy sheet 161 to promote mixing between the materials; and after the extraction and stirring are completed, the drive motor 9 can be turned off. At this time, the swing arm 13 with the counterweight ball end 131 moves downward, and the multiple movable swing plates 132 are retracted. At the same time, the side arm frame 14 stops moving up and down due to the loss of the resistance of the slope ring 19; at this time, the closed movable swing plates 132 and the stopped liquid-dipping disc 15 play a stabilizing role for the stirred material, thereby promoting the rapid stabilization of the material and accelerating the stratification rate of the material;

[0053] After the lower layer of liquid is released through the valved drain pipe 103, the self-locking servo motor 702 can be used to drive the drive gear 703 to rotate, and through the transmission action of the rack 601, the liquid extraction tube 6 is driven to adjust in the vertical direction. When the bottom end of the liquid extraction tube 6 is placed in the upper layer of liquid, the self-locking servo motor 702 stops running and uses its own position ring to lock the position of the liquid extraction tube 6. When the liquid extraction pump 8 is running, it cooperates with the liquid extraction tube 6 and the corrugated hose 602 to extract the upper layer of liquid in the extraction tank 1.
