[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes an oil mist purification and collection device.

[0037] Example 1:

[0038] See also Figures 1-11 An oil mist purification and collection device includes an oil mist purifier 1, the oil mist purifier 1 includes a purification chamber 2 and a filter chamber 3, a purification component 4 and a spray component 5 are provided in the purification chamber 2, a multiple filter component 6 is provided in the filter chamber 3, and a circulation component 7 is provided between the purification chamber 2 and the filter chamber 3;

[0039] The purification assembly 4 includes a plurality of demisters 41, and the plurality of demisters 41 are fixedly installed in the purification chamber 2;

[0040] The spray assembly 5 includes a spray net 51 and a plurality of spray pipes 52. A driving member 53 is provided outside the spray pipe 52. The spray pipe 52 is located between the two demisters 41. The driving member 53 drives the spray pipe 52 to rotate and move back and forth.

[0041] The multi-filtration assembly 6 includes a debris filtration area 61, an oil mist collection area 62, and a water purification area 63. The water mist sprayed by the spray assembly 5 passes through the demister 41, forming water droplets with oil attached thereto. The water droplets then enter the debris filtration area 61. The debris filtration area 61 performs solid-liquid separation on the water droplets, leaving the solids in the debris filtration area 61 and the liquid in the oil mist collection area 62. The oil mist collection area 62 performs liquid-liquid separation on the liquid, leaving the oil mist in the area and the water in the water purification area 63.

[0042] The circulation element 7 transports the water flow in the water purification area 63 to the spray assembly 5 .

[0043] Specifically, the oil mist enters the purification chamber 2 and passes through multiple demisters 41, so that the oil and solid particles in the oil mist adhere to the surface of the demister 41. During the demisting process, the spray net 51 and the spray pipe 52 operate at the same time. The spray net 51 operates to perform secondary purification on the purified gas. The driving member 53 drives the spray pipe 52 to move back and forth between the two demisters 41 while rotating. The high-pressure water flow generated by the spray pipe 52 removes the oil and solid particles on the demister 41, so that the liquid mixed with oil, water and solid particles flows to the filter chamber 3, and the liquid is separated into solids and liquids by the debris filtering area 61 so that the solids remain in the debris filtering area 61. The liquid after solid-liquid separation enters the oil mist collecting area 62, and the oil mist collecting area 62 performs liquid-liquid separation on the liquid so that the oil remains in the oil mist collecting area 62. The filtered water flow enters the clean water area 63, and the circulation member 7 transports the water flow in the clean water area 63 to the spray assembly 5;

[0044] A filter bin 3 is provided at the bottom of the purification bin 2, which is convenient for performing solid-liquid separation and liquid-liquid separation operations on the liquid generated by the spray assembly 5. After the spray assembly 5 cleans the demister 41, the mixed liquid generated thereby enters the debris filtering area 61, and the debris filtering area 61 performs solid-liquid separation on the liquid so that the solid remains in the debris filtering area 61. The liquid after solid-liquid separation enters the oil mist collecting area 62, and the oil mist collecting area 62 performs liquid-liquid separation on the liquid so that the oil remains in the oil mist collecting area 62. The filtered water flows into the clean water area 63, and the circulation component 7 transports the water in the clean water area 63 to the spray assembly 5, thereby achieving separation of oil, solid debris and water, and recycling of water resources, thereby solving the problem of directly excreting the liquid generated when cleaning the demister 41, which would pollute the environment and waste water resources.

[0045] The driving member 53 drives multiple spray pipes 52 to rotate and move back and forth between the two demisters 41. The liquid sprayed by the spray pipes 52 flushes the top and bottom surfaces of the two demisters 41, thereby cleaning each demister 41. This solves the problem that a conventional purifier will install a spray system inside to clean the demister 41. The spray system has a poor cleaning effect on the demister 41 at the bottom of the purifier, making it difficult to form a good cleaning effect on the demister 41, and easily causing the demister 41 to be blocked.

[0046] Example 2:

[0047] The difference from the above embodiment 1 is that, see Figures 1-11 , for the above-mentioned spray assembly 5, the top and bottom of one side of the purification chamber 2 are fixedly connected with an air outlet pipe 8 and an air inlet pipe 9 respectively, and the bottom of the oil mist collection area 62 is fixedly connected with an oil discharge pipe 10;

[0048] The spray net 51 includes multiple water pipes 511 and spray heads 512. A water storage tank 513 is fixedly connected to the top of one side of the purification chamber 2. Multiple water pipes 511 are fixedly installed on the top of the purification chamber 2 and one end extends into the water storage tank 513. Multiple spray heads 512 are fixedly installed at the bottom of the water pipes 511;

[0049] A plurality of spray holes 521 are provided on the spray pipe 52, and guide rail grooves 522 are provided on both sides of the purification chamber 2. Both ends of the spray pipe 52 are rotatably connected to guide rail blocks 523 through bearings. The guide rail blocks 523 are slidably arranged in the guide rail grooves 522. A fixed chamber 524 is fixedly connected to one side of the purification chamber 2, and the fixed chamber 524 is communicated with the purification chamber 2. A hose 525 is rotatably connected to one end of the guide rail blocks 523 through a bearing. One end of the hose 525 is rotatably connected to one end of the spray pipe 52 through a bearing, and the other end of the hose 525 is fixedly connected to the fixed chamber 524.

[0050] The driving member 53 includes an external gear 531 and a tooth plate 532. The external gear 531 is fixedly mounted on the spray pipe 52, and the tooth plate 532 is fixedly mounted in the purification chamber 2. The external gear 531 is meshed with the tooth plate 532. A reciprocating screw rod 533 is rotatably connected to the guide rail groove 522 through a bearing. A sliding block 534 is fixedly connected to the bottom of the guide rail block 523. The sliding block 534 is assembled on the reciprocating screw rod 533 through a thread. Two main gears 535 are rotatably connected to the outside of the purification chamber 2 through a bearing. The main gear 535 is fixedly connected to one end of the reciprocating screw rod 533. The outer sleeves of the two main gears 535 are provided with a toothed belt 536 meshed with the main gears 535. A first motor 537 is fixedly connected to the purification chamber 2, and the output end of the first motor 537 is fixedly connected to one of the main gears 535.

[0051] Specifically, the oil mist enters the purification chamber 2 through the air inlet pipe 9 and passes through multiple demisters 41, so that the oil and solid particles in the oil mist adhere to the surface of the demister 41. During the demisting process, the spray net 51 and the spray pipe 52 operate at the same time. The spray net 51 operates to perform secondary purification on the purified gas. At the same time, the driving member 53 operates, and the first motor 537 drives one of the main gears 535 to rotate. Through the meshing connection between the two main gears 535 and the toothed belt 536, the two main gears 535 are driven to rotate at the same time, thereby driving the two reciprocating screws 533 to rotate at the same time, and passing through the bottom of the guide rail block 523. The setting of the sliding block 534 and the reciprocating screw 533 being threadedly assembled makes it possible for the reciprocating screw 533 to rotate, thereby driving the guide rail block 523 to move back and forth in the guide rail groove 522, thereby driving the spray pipe 52 to move back and forth, through the meshing connection between the external gear 531 and the tooth plate 532 on the outer periphery of the spray pipe 52, and the setting of the simultaneous rotational connection between the spray pipe 52 and the guide rail block 523 and the hose 525 through bearings, so that the spray pipe 52 rotates while moving, and through the setting of the spray hole 521 on the outer periphery of the spray pipe 52, the spray pipe 52 cleans the demister 41 at its top and bottom.

[0052] Example 3:

[0053] The difference from the above embodiment 2 is that, see Figures 1-11 As for the above-mentioned debris filtering area 61, the debris filtering area 61 is fixedly installed on the outside of the purification chamber 2. A passage opening 11 is provided between the debris filtering area 61 and the purification chamber 2. A transport member 12 is provided in the passage opening 11. A movable filter plate 13 is provided between the purification chamber 2 and the filter chamber 3. The filter hole of the movable filter plate 13 is located at the top of the oil mist collection area 62. One end of the movable filter plate 13 is movably hinged to the inner wall of the purification chamber 2. A torsion spring 14 is provided at the hinge between the movable filter plate 13 and the inner wall of the purification chamber 2.

[0054] The debris filtering area 61 is connected to the oil mist collecting area 62 and a filtering channel 15 is provided at the connecting point. A filter screen 16 is fixedly installed in the filtering channel 15.

[0055] The transport member 12 includes a movable rotating plate 121, a rotating roller 122 is rotatably connected to the passage opening 11 through a bearing, and circular plates 123 are fixedly connected to both ends of the rotating roller 122. The circular plates 123 are embedded in the two side walls of the passage opening 11 and rotate with the side walls of the passage opening 11. A plurality of fixed plates 124 are fixedly connected to the outer periphery of the rotating roller 122. An inner groove 125 is provided on the top of the fixed plate 124. The movable rotating plate 121 is slidably arranged in the inner groove 125. A sliding groove 126 is provided on one side of the circular plate 123. Both ends of the bottom of the movable rotating plate 121 are fixedly connected A slider 127 is connected, and the slider 127 is slidably arranged in the slide groove 126. A guide shaft is fixedly connected in the slide groove 126. The slider 127 is sleeved on the guide shaft. First springs 128 are fixedly connected on both sides of the slider 127. The first spring 128 is sleeved on the guide shaft. The top of the movable rotating plate 121 contacts the top and bottom of the channel opening 11. The side of the movable rotating plate 121 contacts one side of the movable filter plate 13. A second motor 129 is fixedly connected to the outside of the channel opening 11. The output end of the second motor 129 is fixedly connected to one end of the rotating roller 122.

[0056] Specifically, the liquid generated by the spray assembly 5 flows downward and is concentrated on the movable filter plate 13. The movable filter plate 13 is tilted to make the liquid on the movable filter plate 13 flow toward the filter holes and the channel opening 11. When the liquid passes through the filter holes, the solid impurities in the liquid will be filtered and left near the movable filter plate 13 and the channel opening 11. The top ends of the two movable rotating plates 121 in the conveying member 12 are in contact with the top and bottom surfaces of the channel opening 11, so that the liquid will not flow into the debris filtering area 61 in large quantities. The second motor 129 drives the rotating roller 122 to rotate, thereby driving the movable rotating plate 121 to rotate. Through the setting of the movable rotating plate 121, the solid debris near the channel opening 11 is transported to the debris filtering area 61. When the movable rotating plate 121 rotates, the movable rotating plate 121 contacts the movable filter plate 13. The movable filter plate 13 is hinged to the inner wall of the purification chamber 2 and the torsion spring 14 is set. Therefore, during the rotation of the movable rotating plate 121, the movable filter plate 13 is driven to vibrate, thereby transporting the solid impurities at the filter holes on the top surface of the movable filter plate 13 to the vicinity of the channel opening 11, and the solid impurities are transported into the debris filtering area 61 through the movable rotating plate 121. During the rotation of the movable rotating plate 121, part of the liquid will be driven to flow into the debris filtering area 61. Through the arrangement that the debris filtering area 61 is connected to the oil mist collecting area 62 and the filter screen 16 is provided at the connection point, and the filter channel 15 is inclined, the liquid in the debris filtering area 61 flows into the oil mist collecting area 62.

[0057] Example 4:

[0058] The difference from the above embodiment 3 is that, see Figures 1-11As for the above-mentioned oil mist collection area 62 and water purification area 63, a filter plate 17 is fixedly connected between the oil mist collection area 62 and the water purification area 63. A scraper 18 is provided on the side of the filter plate 17 close to the oil mist collection area 62. A horizontal plate 19 is fixedly connected to the top of the scraper 18. A telescopic rod 20 is fixedly connected between the bottom of the horizontal plate 19 and the top of the filter plate 17. A second spring 21 is sleeved on the outer periphery of the telescopic rod 20. The top of the horizontal plate 19 is in contact with the bottom of the movable filter plate 13.

[0059] Specifically, the liquid in the debris filtering area 61 flows into the oil mist collecting area 62 after solid-liquid separation. The bottom of the oil mist collecting area 62 and the bottom of the clean water area 63 are both inclined surfaces, so that the liquid in the oil mist collecting area 62 flows into the clean water area 63. The setting of the filter plate 17 makes the oil in the liquid remain in the oil mist collecting area 62, and the water in the liquid flows into the clean water area 63. The setting of the movable filter plate 13 driven by the conveying member 12 to vibrate up and down, and the setting of the second spring 21 arranged on the outer surface of the telescopic rod 20 between the bottom of the cross plate 19 and the top of the filter plate 17, when the conveying member 12 is working, it drives the scraper 18 to scrape the surface of one side of the filter plate 17, thereby preventing the oil from clogging the filter plate 17.

[0060] Embodiment 5:

[0061] The difference from the above-mentioned fourth embodiment is that, see Figures 1-11 As for the circulation component 7, the circulation component 7 includes a water pump 71. A connecting pipe 72 is fixedly connected to the bottom of one side of the water purification area 63. The water pump 71 is fixedly installed on the connecting pipe 72. One side of the connecting pipe 72 is fixedly connected to a plurality of connecting pipe heads 73. The connecting pipe heads 73 are respectively fixedly connected to the hose 525 and the water storage tank 513.

[0062] Specifically, after the setting of the multiple filtering components 6, the liquid sprayed by the spray component 5 is subjected to multiple filtrations, and the cleaned water flows to the clean water area 63. Through the setting of the water pump 71, the water in the clean water area 63 is transported to the water storage tank 513 and the hose 525, thereby achieving the recycling of water resources.
