Description

Technical Field

[0001] This invention relates to the field of petrochemical machinery technology, specifically to an oil collection device for petrochemical machinery. Background Technology

[0002] Petrochemicals refers to the chemical industry based on petroleum and natural gas. Petrochemicals have abundant raw material resources with low cost and high purity. Most petrochemical reactions can produce a series of products with a larger quantity and wider applications than the starting raw material compounds.

[0003] Petrochemical machinery often discharges petroleum during operation, and this discharged petroleum contains a large amount of solid residue. Although existing technologies can filter and recover the discharged petroleum, some problems still exist in the filtration and recovery process:

[0004] 1. Different petrochemical machinery and equipment discharge different types of oil during operation. The existing oil collection device is inconvenient to replace the filter plates used for filtering oil and the oil tanks used for recycling oil in a timely manner. This makes the recycling of oil of different types inconvenient. At the same time, if the filter plates and oil tanks are reused, oil of different types is prone to be mixed, which will affect the quality of the recycled oil.

[0005] 2. In the existing oil recovery devices, it is inconvenient to automatically clean the solid residue on the filter plate in a timely manner when recovering oil, which makes the cleaning of solid residue inconvenient. At the same time, it is inconvenient for operators to collect the solid residue in a unified manner afterward. In order to solve the above problems, the inventor proposes an oil recovery device for petrochemical machinery. Summary of the Invention

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example: Figure 1-12 As shown, the present invention provides an oil collection device for petrochemical machinery, including a collection box 1. A partition plate 11 is fixedly installed on the inner wall of the collection box 1. An oil collection chamber 12 and a residue collection chamber 13 are formed between the two sides of the partition plate 11 and the inner wall of the collection box 1, respectively. An L-shaped inlet pipe 16 is fixedly installed on the upper end face of the collection box 1. An equipment plate 17 is also provided on the upper end face of the collection box 1. The equipment plate 17 is hollow. The end of the L-shaped inlet pipe 16 near the collection box 1 is located above the equipment plate 17. A conical guide bucket 18 is fixedly installed on the side wall of the oil collection chamber 12. The conical guide bucket 18 is located below the equipment plate 17. A filter mechanism 2 is provided inside the equipment plate 17. A filter switching mechanism 3 is provided on the upper end face of the collection box 1. A residue cleaning mechanism 5 is provided on the lower end face of the equipment plate 17. An oil tank switching mechanism 7 is provided on the bottom wall of the oil collection chamber 12.

[0036] By adopting the above technical solution, the collection box 1 is divided into an oil collection chamber 12 and a residue collection chamber 13 by a partition plate 11. Oil is collected in the oil collection chamber 12, and residue in the oil is collected in the residue collection chamber 13. A filter mechanism 2 is set up to facilitate the filtration of oil. A filter switching mechanism 3 and an oil tank switching mechanism 7 are set up to facilitate the filtration of different types of oil and the collection of filtered oil. A residue cleaning mechanism 5 is set up to clean the residue and make it fall into the residue collection chamber 13.

[0037] A front door 14 is hinged to one side of the collection box 1, and a rear door 15 is hinged to the side of the collection box 1 away from the front door 14.

[0038] By adopting the above technical solution, the front chamber door 14 can be opened by rotating it, making it easy for operators to take out the filtered oil from the oil collection chamber 12, and the rear chamber door 15 can be opened by rotating it, making it easy for operators to take out the filtered residue from the residue collection chamber 13.

[0039] The filtration mechanism 2 includes a cross partition 21, which is fixedly connected to the inner wall of the equipment plate 17. Four sector-shaped cavities 22 are formed between the cross partition 21 and the inner wall of the equipment plate 17. A cross baffle 23 is fixedly installed on the upper surface of the cross partition 21. A sector-shaped sealing gasket 24 is provided on the inner wall of the sector-shaped cavity 22. A sector-shaped frame 25 is fixedly installed on the inner wall of the sector-shaped sealing gasket 24. A sector-shaped filter plate 26 is fixedly installed on the inner wall of the sector-shaped frame 25. One end of the L-shaped inlet pipe 16 near the collection box 1 is vertically aligned with one of the sector-shaped filter plates 26. A conical guide bucket 18 is vertically aligned with one of the sector-shaped filter plates 26. The upper opening of the conical guide bucket 18 is larger than the area of ​​the sector-shaped filter plate 26.

[0040] By adopting the above technical solution, by setting the sector-shaped sealing gasket 24, the sealing performance between the sector-shaped frame 25 and the sector-shaped cavity 22 can be improved. By setting four sector-shaped filter plates 26, when different sector-shaped filter plates 26 are vertically aligned with the L-shaped inlet pipe 16, it is convenient to filter different oil products. The filtered oil drips downward through the conical guide bucket 18, and the residue filtered out in the oil stays on the upper surface of the sector-shaped filter plate 26.

[0041] The fan-shaped filter plate 26 is inclined away from the axis of the equipment plate 17 and is set on the inner wall of the fan-shaped frame 25. The fan-shaped frame 25 and the fan-shaped sealing gasket 24 are both provided with a slag discharge groove 27 on one side. The bottom wall of the slag discharge groove 27 is horizontally aligned with the upper surface of the fan-shaped filter plate 26.

[0042] By adopting the above technical solution, by setting the slag discharge trough 27, the waste residue on the fan-shaped filter plate 26 can be discharged through the slag discharge trough 27 and fall into the residue collection chamber 13. By setting the cross baffle 23, when the residue on the upper surface of one fan-shaped filter plate 26 is discharged through the slag discharge trough 27, the cross baffle 23 prevents the residue on one fan-shaped filter plate 26 from falling onto the upper surface of the other two fan-shaped filter plates 26.

[0043] The filter switching mechanism 3 includes four first rotating shafts 31. One end of each of the four first rotating shafts 31 is rotatably connected to the upper end of the collection box 1. The other end of each of the four first rotating shafts 31 is fixedly mounted with a transmission wheel 32. A transmission belt 33 is installed between the four transmission wheels 32. A plurality of evenly distributed first teeth 34 are fixedly installed on the inner wall of the transmission belt 33. A first transmission rod 35 is rotatably mounted on the side wall of the residue collection chamber 13. A first gear 36 is fixedly mounted on one end of the first transmission rod 35. The first teeth 34 and the first gear 36 are at the same height. A first rotating rod 37 is fixedly mounted on the upper surface of the cross baffle 23. A synchronous pulley 38 is fixedly mounted on the middle of the first transmission rod 35 and one end of the first rotating rod 37. A synchronous belt 39 is connected between the two synchronous pulleys 38.

[0044] By adopting the above technical solution, by driving a first rotating shaft 31 to rotate, four first rotating shafts 31 and four transmission wheels 32 rotate synchronously, and the transmission belt 33 transmits the power. The transmission belt 33 causes the first tooth 34 to move synchronously. When the first tooth 34 meshes with the first gear 36, the first tooth 34 drives the first gear 36 to rotate. The first gear 36 causes the first transmission rod 35 to rotate. The first transmission rod 35 causes the first rotating rod 37 to rotate through two synchronous wheels 38 and synchronous belt 39. The first rotating rod 37 causes the equipment disc 17 and four sector filter plates 26 to rotate synchronously through cross baffles 23 and cross partitions 21. When the four sector filter plates 26 rotate once, another sector filter plate 26 is vertically aligned with the conical guide bucket 18. When the first tooth 34 disengages from the first gear 36, the four sector filter plates 26 stop rotating.

[0045] A first motor 4 is fixedly installed on the other side of the collection box 1. A second rotating rod 41 is fixedly installed on the drive output end of the first motor 4. A first bevel gear 42 is fixedly installed on the end of the second rotating rod 41 away from the first motor 4 and on one of the first rotating shafts 31. The two first bevel gears 42 mesh with each other. A circular slide rail 43 is fixedly installed on the side wall of the oil collection chamber 12 and the residue collection chamber 13. The circular slide rail 43 is coaxial with the equipment plate 17. Two arc-shaped sliders 44 are slidably installed on the inner wall of the circular slide rail 43. A connecting rod 45 is fixedly installed on the opposite side of the two arc-shaped sliders 44. One end of the two connecting rods 45 is fixedly connected to the outer wall of the equipment plate 17.

[0046] By adopting the above technical solution, by turning on the first motor 4, the drive shaft of the first motor 4 causes the second rotating rod 41 to rotate. The second rotating rod 41 causes a first rotating shaft 31 to rotate through two first bevel gears 42. By setting up a circular slide rail 43, an arc-shaped slider 44 and a connecting rod 45, when the equipment disk 17 rotates, the equipment disk 17 causes the arc-shaped slider 44 to slide around the axis of the circular slide rail 43 through the connecting rod 45. The connecting rod 45 and the arc-shaped slider 44 support the equipment disk 17 and improve the stability of the equipment disk 17.

[0047] The residue cleaning mechanism 5 includes a lifting plate 51, located below the equipment plate 17. Two push plates 53 are fixedly mounted on the upper surface of the lifting plate 51. The ends of the two push plates 53 away from the lifting plate 51 are in movable contact with the lower surface of another sector frame 25. A counterweight 54 is fixedly mounted on the lower surface of the lifting plate 51. An arc-shaped groove 55 is formed on the side of the counterweight 54 away from the lifting plate 51. Several guide grooves 56 are arranged in a ring-shaped array on the inner wall of the equipment plate 17. Guide blocks 57 are slidably connected to the inner wall of the guide grooves 56. An L-shaped connecting frame 58 is fixedly mounted on one side of the guide block 57. One end of two adjacent L-shaped connecting frames 58 is fixedly connected to the lower surface of a sector frame 25. A telescopic rod 59 is fixedly mounted on one end of the guide groove 56. The piston end of the telescopic rod 59 is fixedly connected to the upper surface of the guide block 57. A return spring 6 is movably sleeved on the outer wall of the telescopic rod 59. One end of the positioning spring 6 is fixedly connected to one end of the guide groove 56, and the other end of the reset spring 6 is fixedly connected to the upper surface of the guide block 57. A third rotating rod 61 is rotatably installed on the other side of the collection box 1. The third rotating rod 61 passes through the partition plate 11 and is rotatably connected to the partition plate 11. A cam 62 is fixedly installed on one end of the third rotating rod 61. The cam 62 is vertically aligned with the arc groove 55. A second transmission rod 63 is also rotatably installed on the other side of the collection box 1. A second bevel gear 64 is fixedly installed on one end of the second transmission rod 63 and the end of the third rotating rod 61 away from the cam 62. The two second bevel gears 64 mesh with each other. A second gear 65 is fixedly installed on the other end of the second transmission rod 63. A number of evenly distributed second teeth 66 are fixedly installed on the outer wall of the transmission belt 33. The second teeth 66 are staggered from the first teeth 34 and are at the same height as the second gear 65.

[0048] By adopting the above technical solution, when the transmission belt 33 transmits, after the first tooth 34 disengages from the first gear 36, the second tooth 66 meshes with the second gear 65 and drives the second gear 65 to rotate. The second gear 65 causes the second transmission rod 63 to rotate. The second transmission rod 63 causes the third rotating rod 61 to rotate through two second bevel gears 64. The third rotating rod 61 causes the cam 62 to rotate. The protruding part of the cam 62 contacts the arc groove 55 and causes the lifting plate 51 and the push plate 53 to rise vertically through the counterweight 54. The push plate 53 pushes a sector frame 25 and a sector filter plate 26 to rise vertically. After the sector filter plate 26 rises, the residue on its upper surface is discharged into the residue collection chamber 13 through the slag discharge trough 27. Meanwhile, the sector frame 25 causes the guide block 57 to rise vertically along the inner wall of the guide groove 56 via two L-shaped connecting brackets 58. The guide block 57 presses the telescopic rod 59 and the return spring 6. When the cam 62 disengages from the arc groove 55, the counterweight 54 drives the lifting plate 51 and the push plate 53 to descend vertically and return to their original positions. The sector frame 25 loses its upward thrust, and the telescopic rod 59 and the return spring 6 retract, pushing the guide block 57 to slide downward. The guide block 57 causes the sector frame 25 and the sector filter plate 26 to descend vertically and return to their original positions via the L-shaped connecting brackets 58. When the second tooth 66 disengages from the second gear 65, the cam 62 stops rotating, and the sector frame 25 and the sector filter plate 26 stop reciprocating up and down and return to their initial height.

[0049] Two L-shaped guide rods 52 are fixedly installed on the side wall of the oil receiving chamber 12, and the lifting plate 51 and the two L-shaped guide rods 52 are slidably connected.

[0050] By adopting the above technical solution, and by setting an L-shaped guide rod 52, the L-shaped guide rod 52 guides the lifting plate 51 in the vertical direction, so that the lifting plate 51 keeps rising and falling in the vertical direction.

[0051] The oil tank switching mechanism 7 includes a rotating disk 71, which is in contact with the bottom wall of the oil receiving chamber 12. Four oil receiving tanks 72 arranged in a ring array are fixedly installed on the upper surface of the rotating disk 71. A conical guide bucket 18 is located above the oil receiving tanks 72 and is vertically aligned with one of the oil receiving tanks 72. A second rotating shaft 73 is rotatably installed on the lower end face of the collection box 1. One end of the second rotating shaft 73 is fixedly connected to the lower surface of the rotating disk 71. A grooved wheel 74 is fixedly installed on the end of the second rotating shaft 73 away from the rotating disk 71.

[0052] By adopting the above technical solution, four oil collection tanks 72 are set up, which are vertically aligned with four sector-shaped filter plates 26. When the four sector-shaped filter plates 26 rotate once, the four oil collection tanks 72 rotate once. One oil collection tank 72 that has not collected oil is vertically aligned with one sector-shaped filter plate 26 that has not filtered oil, thereby realizing the classified collection of different oil products. By driving the groove wheel 74 to rotate once, the groove wheel 74 causes the four oil collection tanks 72 to rotate once through the second rotating shaft 73 and the rotating disk 71.

[0053] A second motor 75 is fixedly installed on the lower end face of the collection box 1. A fourth rotating rod 76 is fixedly installed on the drive output end of the second motor 75. A fixed plate 77 is fixedly installed on the end of the fourth rotating rod 76 away from the second motor 75. A drive plate 78 is fixedly installed on the side of the fixed plate 77 away from the fourth rotating rod 76. A drive rod 79 is fixedly installed on the side of the fixed plate 77 close to the drive plate 78. The diameter of the drive rod 79 is the same as the groove width of the groove wheel 74.

[0054] By adopting the above technical solution, by turning on the second motor 75, the drive shaft of the second motor 75 causes the fixed disk 77, the drive disk 78 and the drive rod 79 to rotate through the fourth rotating rod 76. The drive rod 79 revolves around the axis of the fixed disk 77. When the drive rod 79 contacts one slot of the groove wheel 74, the drive rod 79 causes the groove wheel 74 to rotate a quarter turn through one slot, thereby completing the switching of the four oil receiving tanks 72.

[0055] Working principle: When oil needs to be recovered, the operator first introduces the oil to be recovered into a sector-shaped filter plate 26 through the L-shaped inlet pipe 16. The introduced oil drips onto the upper surface of the sector-shaped filter plate 26, which filters the oil. The filtered oil drips through the conical guide bucket 18 into a vertically corresponding oil collection tank 72. The residue in the oil remains on the upper surface of the sector-shaped filter plate 26.

[0056] When it is necessary to recover oil of different types, the operator first turns on the first motor 4. The drive shaft of the first motor 4 causes the second rotating rod 41 to rotate. The second rotating rod 41 causes the corresponding first rotating shaft 31 to rotate through two first bevel gears 42. At this time, the four first rotating shafts 31 and the four transmission wheels 32 rotate synchronously. The transmission belt 33 follows the transmission, and the transmission belt 33 causes multiple first teeth 34 and multiple second teeth 66 to move synchronously.

[0057] First, multiple first teeth 34 mesh with the first gear 36, driving the first gear 36 to rotate. The first gear 36 then rotates the first transmission rod 35. The first transmission rod 35, through two synchronous pulleys 38 and a synchronous belt 39, causes the first rotating rod 37 to rotate. The first rotating rod 37, through a cross stop bar 23 and a cross partition 21, causes the equipment disc 17 and four sector-shaped filter plates 26 to rotate synchronously. After the four sector-shaped filter plates 26 rotate once, another sector-shaped filter plate 26 aligns vertically with the conical guide bucket 18. Simultaneously, the multiple first teeth 34 disengage from the first gear 36, and the four sector-shaped filter plates 26 stop rotating. During this process, the second motor 75 is simultaneously activated. The drive shaft of the second motor 75, through the fourth rotating rod 76, causes the fixed disc 77, the drive disc 78, and the drive rod 79 to rotate. The drive rod 79 revolves around the axis of the fixed disk 77. When the drive rod 79 contacts one slot of the groove wheel 74, the drive rod 79 causes the groove wheel 74 to rotate a quarter turn through the slot. The groove wheel 74 causes the four oil collection tanks 72 to rotate once through the second rotating shaft 73 and the rotating disk 71. At this time, one oil collection tank 72 that has not recovered oil and one sector filter plate 26 that has not filtered oil are vertically aligned. Then, according to the operation steps described above, the filtration and recovery of another type of oil is completed, thus conveniently realizing the filtration and recovery of different types of oil. This effectively improves the convenience of recovering different types of oil. At the same time, it avoids the mixing of different types of oil due to the repeated use of the sector filter plate 26 and the oil collection tank 72, thus avoiding the impact on the quality of the recovered oil.

[0058] Simultaneously, as multiple first teeth 34 disengage from the first gear 36, multiple second teeth 66 mesh with the second gear 65, driving the second gear 65 to rotate (at this time, the multiple sector-shaped filter plates 26 are in a stopped state). The second gear 65 causes the second transmission rod 63 to rotate, and the second transmission rod 63 causes the third rotating rod 61 to rotate through two second bevel gears 64. The third rotating rod 61 causes the cam 62 to rotate. When the protruding part of the cam 62 contacts the inner wall of the arc groove 55, the cam 62 causes the lifting plate 51 and two pushers to rotate through the counterweight 54. Plate 53 rises vertically, and two push plates 53 push a corresponding sector frame 25 and a sector filter plate 26 (the sector filter plate 26 has residue from the oil) to rise vertically. After the sector filter plate 26 rises, because the sector filter plate 26 is inclined, the residue on its upper surface is discharged into the residue collection chamber 13 through the slag discharge trough 27. At the same time, a sector frame 25 causes two guide blocks 57 to rise vertically along the inner wall of the corresponding guide groove 56 through two L-shaped connecting frames 58. The two guide blocks 57 press against two telescopic rods 59 and two composite rods 50. When the cam 62 disengages from the inner wall of the arc groove 55, the counterweight 54 drives the lifting plate 51 and the two push plates 53 to descend vertically and reset. A sector frame 25 loses its upward thrust. At this time, the two telescopic rods 59 and the two reset springs 6 retract, pushing the two guide blocks 57 to slide downwards. The two guide blocks 57, through the two L-shaped connecting brackets 58, cause a sector frame 25 and a sector filter plate 26 to descend vertically and reset. During the meshing of the multiple second teeth 66 and the second gear 65, the cam 62 rotates several times, causing a sector... The filter plate 26 reciprocates multiple times. When multiple second teeth 66 disengage from the second gear 65, the cam 62 stops rotating. A sector frame 25 and a sector filter plate 26 stop reciprocating and return to their initial height. During this period, as a sector filter plate 26 reciprocates multiple times, the residue on the sector filter plate 26 is completely discharged into the residue collection chamber 13, thus facilitating the automatic cleaning and collection of residue. This effectively improves the convenience of cleaning residue and makes it easier for subsequent operators to collect the residue uniformly.
