Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and more particularly to an oil-water separation device for natural citral oily wastewater. Background Art

[0002] Natural citral refers to natural citral, an organic compound with a special aroma, usually found in citrus fruits such as lemon peel and orange peel. It is a colorless or light yellow liquid with a strong aroma and volatility. In terms of chemical structure, natural citral is mainly composed of two isomers, namely citral A and citral B, which have similar chemical properties but slightly different physical properties. In natural citral oily wastewater, citral is usually mixed with other organic matter such as oil and fat. If this wastewater is discharged directly without treatment, it will not only pollute the environment, but also waste precious citral resources. Therefore, the development of an efficient oil-water separation device to achieve effective treatment of natural citral oily wastewater has important practical significance and application value.

[0003] According to patent document: CN118561369B, an oil-water separation device for treating oily wastewater is disclosed, which relates to the technical field of wastewater treatment devices, including reinforced support legs, a gravity separation mechanism is provided on the top of the reinforced support legs, a freezing separation mechanism is provided on the outer wall of the reinforced support legs, the gravity separation mechanism includes an oil-water separation unit and a demulsification heating unit, the freezing separation mechanism includes a drive transposition unit and a temperature adjustment unit, and the demulsification heating unit includes a movable round seat. The present invention is designed with a liquid inlet pipe, so that the user can inject an external demulsifier into the inner cavity of the hollow square tube. Through the design of the rotary joint, the movable round seat and the manual drive handle, the user can manually rotate the hollow square tube as a whole. The demulsifier will then be evenly output from the one-way injection pipe into the interior of the wastewater, destroying the emulsified oil body inside the wastewater, causing the emulsified oil body to float up, thereby ensuring the adequacy of subsequent oil-water separation.

[0004] During the processing of natural citral, some wastewater will be produced. In these wastewaters, there will usually be a part of the natural citral residue produced during the processing. These residues may mix with some oil bodies in the wastewater to form a relatively stable emulsion. The existence of this emulsion greatly increases the difficulty of oil-water separation, making wastewater treatment more complicated and difficult. Summary of the Invention

The front end of the second set of rods 417 is fixedly connected to the second motor 412, and the bottom of the second motor 412 is fixedly connected to the second motor support plate 411. The front side of the motor support plate 411 is fixedly connected to the front side of the waste oil discharge funnel 415. The side of the oil-absorbing paper roller 45 away from the sleeve rod 44 extends to the right side of the oil-water separation tank 41 through the two oil-absorbing paper grooves 42 opened in the oil-water separation tank 41 and is sleeved on the outer wall of one side of the second sleeve rod 417 on the inner side of the two second sleeve rod connecting blocks 416. The bottom of the oil-absorbing paper roller 45 passes through the oil-absorbing paper groove 42 opened on the right side of the oil-water separation tank 41, and is in contact with the bottom C-shaped side plate 418, and the top is in contact with the outer wall of the columnar extrusion rod 4113.

[0035] When it is necessary to separate oil and water from the oily wastewater, the wastewater inlet pipe 62 is connected to the pipeline, and the oily wastewater after natural citral processing is discharged through the wastewater inlet pipe 62. The oily wastewater first passes through the residue filter bag 6111 and the filter screen at the bottom of the residue filter bag 6111 to filter the residue on the inner wall of the residue filter bag 6111. The oily wastewater is discharged into the oil-water separation tank 41. When the residue in the residue filter bag 6111 is full, the residue filter bag 6111 cannot continue to flow wastewater downward. At this time, the two-way liquid is started. After the bidirectional hydraulic push rod 69 is activated, its left and right ends push the L-shaped expansion rod 610 to move inward synchronously, and the L-shaped expansion rod 610 drives the expansion plate 611 to move accordingly. Since the V-shaped rotation rod 612 on the outside of the expansion plate 611 is rotatably connected to the inner wall of the hinge block 66, the expansion plate 611 pushes one end of the V-shaped rotation rod 612 to rotate inward and the other end to rotate outward during the inward movement, thereby driving the baffle push rod 613 to slide on the top inner wall of the guide rod 65, so that the baffles 614 move away from each other;

[0036] At the same time, the columnar horizontal push rod 615 on the inner side of the expansion plate 611 slides on the inner wall of the guide block 67, and the columnar horizontal push rod 615 drives the L-shaped push rod 616 and the clamping plate 617 to move accordingly. Since the clamping plate 617 is located on the left and right sides of the residue filter bag connecting frame 6110, the clamping plate 617 will squeeze the residue filter bag connecting frame 6110 and the residue filter bag 6111 inside it toward the outside of the oil-water separation tank 41 during the movement, so that the oil and water absorbed by the residue in the residue filter bag 6111 are completely squeezed into the oil-water separation tank 41. After cleaning is completed, the two-way hydraulic push rod 69 is started in the reverse direction to drive the various components to reset, and then a new residue filter bag 6111 is installed in the residue filter bag connecting frame 6110 for continued use;

[0037] During the oil-water separation process, the bidirectional hydraulic push rod 69 pushes the L-shaped expansion rods 610 on both sides to move outward. The outward movement of the two sets of L-shaped expansion rods 610 causes the tops of the two sets of V-shaped rotation rods 612 to rotate inward, thereby causing the two sets of baffle push rods 613 to move inward and drive the two baffles 614 to close the top of the wastewater inlet pipe 62, thereby preventing the continuous discharge of wastewater during the oil-water separation process, which would reduce the oil-water separation effect.

[0038] When the oily wastewater is discharged into the oil-water separation tank 41, the motor 47 and the second motor 412 are started. The speed of the second motor 412 is lower than that of the motor 47. The output end of the motor 47 drives the transmission disc 48 to rotate. The transmission disc 48 drives the second turntable 410 to rotate through the crawler 49. The inner wall of the second turntable 410 is fixedly connected to the outer wall of the sleeve rod 44, so the sleeve rod 44 rotates accordingly, and the sleeve rod 44 drives the oil-absorbing paper roller 45 to move in the oil-water separation tank 41. The oil-absorbing paper on the oil-absorbing paper roller 45 absorbs the floating oil in the oil-water separation tank 41. As the oil-absorbing paper roller 45 continues to move, more and more oil floats on the oil-absorbing paper. When the oil-absorbing paper moves to the right side of the oil-water separation tank 41, the second motor 412 starts to drive the second set of rods 417 to drive the oil-absorbing paper roller 45 to reel the oil-absorbing paper, because the second motor 412 has a lower speed than the motor 47. The wastewater after the oil is absorbed is directly discharged into the wastewater discharge pipe 414 through the oil-water separation tank 41 and then discharged into the wastewater collection pipe in the oil-water drainage pipe 5 through the wastewater discharge pipe 414, and then discharged into the wastewater treatment tank 1.

[0039] As the oil absorbed by the oil absorbing paper moves, the columnar squeezing rod 4113 is always in contact with the oil absorbing paper roller 45 under the elastic force of the spring 4111, squeezing the waste oil absorbed by the oil absorbing paper into the waste oil discharge funnel 415 before the oil absorbing paper is rolled up. The waste oil is finally discharged into the waste oil collection pipe of the oil-water drainage pipe 5 through the waste oil discharge funnel 415 and then discharged into the waste oil receiving barrel 3, thereby completing the collection of floating oil.

[0040] After the oil-absorbing paper is completely rolled up on the outer wall of the second sleeve rod 417, when the next wastewater oil-water separation is required, the motor 47 can be started in the reverse direction to roll the oil-absorbing paper toward the side of the sleeve rod 44. The floating oil absorbed last time is squeezed by the columnar squeezing rod 4113 into the waste oil discharge funnel 415 and discharged. At this time, the oil-absorbing paper has been drained and can absorb floating oil again, and then contact the floating oil in the oil-water separation tank 41 again to perform a new round of oil-water separation.

[0041] Working principle of the present invention: when it is necessary to separate oil-water from oily wastewater, the wastewater inlet pipe 62 is connected to the pipeline, and the oily wastewater after processing of natural citral is discharged through the wastewater inlet pipe 62, and the oily wastewater is first filtered through the residue filter bag 6111 through the filter screen at the bottom of the residue filter bag 6111, so that the residue is filtered on the inner wall of the residue filter bag 6111, and the oily wastewater is discharged into the oil-water separation tank 41. When the residue in the residue filter bag 6111 is full, the residue filter bag 6111 cannot continue to flow wastewater downward, and the two-way hydraulic push rod 69 is started. After the two-way hydraulic push rod 69 is started, its left and right ends push the L-shaped expansion rod 610 to move inward synchronously, and the L-shaped expansion rod 610 drives the expansion plate 611 to move accordingly, and the expansion plate During the inward movement, 611 pushes one end of the V-shaped rotating rod 612 to rotate inward and the other end to rotate outward, thereby driving the baffle push rod 613 to slide on the top inner wall of the guide vertical rod 65, so that the baffles 614 move away from each other. At the same time, the columnar horizontal push rod 615 on the inner side of the expansion plate 611 slides on the inner wall of the guide block 67, and the columnar horizontal push rod 615 drives the L-shaped push rod 616 and the clamping plate 617 to move accordingly. Since the clamping plate 617 is located on the left and right sides of the residue filter bag connecting frame 6110, the clamping plate 617 will squeeze the residue filter bag connecting frame 6110 and the residue filter bag 6111 inside it toward the outside of the oil-water separation tank 41 during the movement, so that the oil and water adsorbed in the residue in the residue filter bag 6111 are completely removed. The oil is fully squeezed into the oil-water separation tank 41. During the oil-water separation process, the two-way hydraulic push rod 69 pushes the L-shaped expansion rods 610 on both sides to move outward. The two L-shaped expansion rods 610 move outward, thereby causing the tops of the two groups of V-shaped rotating rods 612 to rotate inward, thereby causing the two groups of baffle push rods 613 to move inward and drive the two baffles 614 to close the top of the wastewater inlet pipe 62. When the oily wastewater is discharged into the oil-water separation tank 41, the motor 47 and the second motor 412 are started at this time. The speed of the second motor 412 is lower than that of the motor 47. The output end of the motor 47 drives the transmission disc 48 to rotate. The transmission disc 48 drives the second turntable 410 to rotate through the crawler 49. The inner wall of the second turntable 410 is fixedly connected to the sleeve rod 44, so the sleeve rod 44 rotates accordingly, and the sleeve rod 44 drives the oil-absorbing paper roller 45 to move in the oil-water separation tank 41, and the oil-absorbing paper on the oil-absorbing paper roller 45 absorbs the floating oil in the oil-water separation tank 41. As the oil-absorbing paper roller 45 continues to move, more and more floating oil is on the oil-absorbing paper. When the oil-absorbing paper moves to the right side of the oil-water separation tank 41, since the second motor 412 and the speed of the second motor 412 are lower than that of the motor 47, the second motor 412 starts to drive the second sleeve rod 417 to drive the oil-absorbing paper roller 45 to reel the oil-absorbing paper. The waste water after the oil is absorbed is directly discharged into the wastewater discharge pipe 414 through the oil-water separation tank 41 and discharged into the wastewater collection pipe in the oil-water drainage pipe 5 through the wastewater discharge pipe 414, and then discharged into the wastewater treatment tank 1.As the oil-absorbing paper roller 45 moves, the columnar squeezing rod 4113 is always in contact with the oil-absorbing paper roller 45 under the elastic force of the spring 4111, squeezing the waste oil absorbed by the oil-absorbing paper before it is rolled up into the waste oil discharge funnel 415, and finally discharged into the waste oil collection pipe of the oil-water drainage pipe 5 through the waste oil discharge funnel 415 and discharged into the waste oil receiving barrel 3, completing the collection of floating oil. After the oil-absorbing paper is completely rolled up on the outer wall of the second sleeve rod 417, when it is necessary to separate the wastewater from oil and water for the next time, the motor 47 can be started in the reverse direction to roll the oil-absorbing paper toward one side of the sleeve rod 44, and the floating oil absorbed last time is squeezed by the columnar squeezing rod 4113 into the waste oil discharge funnel 415 and discharged. At this time, the oil-absorbing paper has been completely discharged and can absorb floating oil again and contact the floating oil in the oil-water separation tank 41 again to carry out a new round of oil-water separation.
