DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0032] like Figure 1 and Figure 2 As shown, an oil separation device for an air compressor with a filtering function comprises two sealing covers 1. An air inlet is arranged at the left end of the sealing cover 1 on the left side, and the air in the air compressor can enter the device through the air inlet. A separation box 2 for precipitating and separating oil and water is arranged between the two sealing covers 1. Air will enter the separation box 2, and then the oil and water in the air will be screened out and then placed together. The density of water is greater than that of oil. When oil and water are placed in a container at the same time, the oil will float on the water surface, and the separated oil and water can be discharged separately. A limiting mechanism 3 for controlling the oil output is arranged on the right side of the inner cavity of the separation box 2. The limiting mechanism 3 also needs to limit the components in the separation box 2. When the device is drained of oil through the limiting mechanism 3, the limiting effect on the components in the separation box 2 will be contacted;

[0033] Then, an oil scraper mechanism 4 for moving the oil is provided in the middle of the inner cavity of the separation box 2. After the oil-water separation is completed, the mixed liquid cannot be directly stirred, otherwise the separation state of the oil and water will be destroyed. The components in the oil scraper mechanism 4 can float on the water surface and then move the floating oil on the water surface. Without affecting the oil-water separation state, the floating oil in the device will not be unable to be discharged for a long time. A discharge mechanism 5 for controlling the water output is provided on the lower left side of the oil scraper mechanism 4. When a lot of water is collected in the device, a certain amount of water can be discharged through the discharge mechanism 5 to maintain the oil-water separation state in the device. A quantitative component 6 is provided on the left side of the discharge mechanism 5. The quantitative component 6 cooperates with the discharge mechanism 5 to allow the device to release a certain amount of water. A filter tube 7 is provided on the arc surface of the sealing cover 1 on the left.

[0034] It should be noted that the filter tube 7 can be used to filter the liquid entering the device. When the device is draining oil, a part of the floating oil will never be discharged and will remain in the device. After being left for a period of time, the floating oil that has not been discharged from the device will solidify and deteriorate, emit odor and clog the device, so the oil scraping mechanism 4 is needed to clean it.

[0035] Further explanation: In order to separate the oil and water in the air, Figure 3 As shown, the separation box 2 includes a box body 21, and the oil and water in the air will fall into the box body 21, and then the oil and water separation work will be carried out in the box body 21. The left and right ends of the box body 21 are fixedly installed with connecting rings 22, and the upper side of the arc-shaped inner wall of the box body 21 is fixedly installed with a mist catcher 23. The air will be discharged from the box body 21 through the mist catcher 23, and the oil and water droplets in the air will be captured by the mist catcher 23, and then fall into the box body 21 for storage. A plurality of wave-breaking plates 24 are provided in the middle of the inner cavity of the box body 21, and the oil and water are stored in the box body 21. When the water is discharged, the water surface will float back and forth, which is easy to affect the separation state of the oil and water. The wave-breaking plates 24 can ensure the floating amplitude of the oil surface, so that the oil-water separation state will not be destroyed;

[0036] Then, a wind shield 25 is fixedly installed on the upper side of the arc-shaped inner wall of the connecting ring 22 on the left side. When the air enters the device, it will be blocked by the wind shield 25, so that it is completely filled in the box body 21, so that when the air is added into the box body 21, it cannot contact the mist collector 23 at the first time, so as to ensure the normal use of the mist collector 23. An oil outlet pipe is provided on the lower side of the arc-shaped inner wall of the connecting ring 22 on the right side, and the separated oil will be discharged through the oil outlet pipe. A number of supporting legs 26 for supporting the device are fixedly installed at the lower end of the box body 21.

[0037] It should be noted that only when the air in the box 21 is discharged outward from the mist collector 23 in an orderly manner can the oil and water droplets in the air be captured to the maximum extent. If the air is discharged directly through the mist collector 23, the air will be affected in the capture work of the mist collector 23 when it enters and exits at the same time.

[0038] Further explanation, in order to manually control the switch of the oil outlet pipe, such as Figure 4 As shown, the limiting mechanism 3 includes a cylinder 31, the output end of the cylinder 31 passes through the inner cavity of the box body 21 and is fixedly installed with an L-shaped plate 32. Starting the cylinder 31 can drive the L-shaped plate 32 to move left and right, and the L-shaped plate 32 plays a role in limiting the oil scraping mechanism 4. A sealing plate 33 is slidably installed on the lower side of the arc-shaped inner wall of the connecting ring 22 on the right side. The sealing plate 33 fits tightly against the inner wall of the connecting ring 22, and the L-shaped plate 32 and the sealing plate 33 are connected to each other. In the initial state of the device, the sealing plate 33 is located directly above the oil outlet pipe, and the sealing plate 33 will block the oil outlet pipe, so that the oil in the device cannot be discharged.

[0039] Further explanation, in order to be able to move the oil slick and understand the water level in the box 21, as Figure 4 As shown, the oil scraping mechanism 4 includes a motor 41, and two mutually meshing bevel gears 1 42 are provided on the right side of the motor 41, and the bevel gear 1 42 located on the left side is connected to the output end of the motor 41. Starting the motor 41 can drive the two bevel gears 1 42 to rotate simultaneously, and a telescopic rod 43 is fixedly installed on the upper end of the bevel gear 1 42 located on the upper side, and a sealing box 44 is provided on the upper side of the telescopic rod 43. Two mutually meshing bevel gears 2 45 are provided in the inner cavity of the sealing box 44. The sealing box 44 has a certain sealing effect, which can prevent water in the box body 21 from entering the sealing box 44, and ensure that the bevel gear 2 45 will not rust and cannot be used;

[0040] Then, the bevel gear 2 45 located on the lower side is connected to the telescopic rod 43 located on the right side. The telescopic rod 43 can drive the two bevel gears 2 45 to rotate simultaneously through the bevel gear 1 42, and the telescopic rod 43 is composed of two components, a movable cross rod and a fixed support tube, and the inner cavity of the support tube is also cross-shaped, so that when the cross rod moves up and down in the support tube, it will not affect the transmission between the bevel gear 1 42 and the bevel gear 2 45. A movable component 46 is provided on the left side of the sealing box 44.

[0041] To further explain, in order to move the oil floating on the water surface, Figure 5 and Figure 6As shown, the movable component 46 includes a convex plate 461. When the device is in the initial state, the convex plate 461 is limited by the L-shaped plate 32. When the L-shaped plate 32 moves to the right, the limit can be released. A reciprocating screw 462 is rotatably installed in the inner cavity of the convex plate 461. The reciprocating screw 462 is connected to the bevel gear 2 45 located on the upper side. The bevel gear 2 45 can drive the reciprocating screw 462 to rotate. A rectangular plate 463 is provided on the upper side of the reciprocating screw 462. The lower end of the rectangular plate 463 is tightly attached to the upper end of the convex plate 461. The rectangular plate 463 is threadedly connected to the reciprocating screw 462 using a nut. When the reciprocating screw 462 rotates, it can drive the rectangular plate 463 to move left and right.

[0042] Then, an oil scraper plate 467 is rotatably installed in the inner cavity of the rectangular plate 463. When the oil scraper plate 467 moves to the right, it will be limited by the rectangular plate 463, so that the oil scraper plate 467 will remain in a vertical state, which can push the floating oil to move to the right to the greatest extent. A take-up roller 464 is rotatably installed on the left side of the lower end of the convex plate 461, and a spring box 465 is provided at the front end of the take-up roller 464. When the take-up roller 464 rotates, the spring box 465 will store energy. After the take-up roller 464 stops rotating, the spring box 465 can drive the take-up roller 464 to reset. A number of air bags 466 are fixedly installed on the lower end of the convex plate 461, which are dragged by the air bags 466 to move upward in the water and then blocked by the floating oil, so that the convex plate 461 can be located between the water surface and the floating oil and remain stationary.

[0043] The specific implementation of this embodiment is as follows: after the air with oil and water enters the device, it will be blocked by the windshield 25 and then filled in the box 21. The air in the box 21 will be discharged from the mist collector 23 in an orderly manner. The mist collector 23 captures the oil and water droplets in the air and then drops them into the box 21 for collection. When the box 21 has more oil and water, the cylinder 31 can be started to drive the L-shaped plate 32 and the sealing plate 33 to move to the right at the same time. The sealing plate 33 cannot block the oil outlet pipe, so that the device can discharge the overflowed oil.

[0044] When the L-shaped plate 32 moves to the right, the convex plate 461 can no longer be limited. The airbag 466 is located in the water and has an upward buoyancy. Under the push of the airbag 466, the convex plate 461 moves upward and is then blocked by the floating oil on the water surface, so that the convex plate 461 is located between the water surface and the floating oil. The device can judge the water level in the box 21 through the position of the convex plate 461, and can also obtain the oil and water content in the box 21.

[0045] Start the motor 41 to drive the two bevel gears 42 to rotate at the same time, and the telescopic rod 43 will extend as the convex plate 461 moves. The bevel gear 42 on the right side can drive the two sealing boxes 44 to rotate at the same time through the telescopic rod 43, and the bevel gear 2 45 on the upper side can drive the reciprocating screw 462 to rotate. When the reciprocating screw 462 rotates, it can drive the rectangular plate 463 and the oil scraper plate 467 to move left and right. When the oil scraper plate 467 moves to the right, it will be limited by the rectangular plate 463, so that the oil scraper plate 467 will remain in a vertical state, which can push the floating oil to the right to the greatest extent. When the oil scraper plate 467 moves to the left, it will rotate clockwise under the resistance of the oil, and will not push the floating oil to move to the left, thereby reducing the retention time of the floating oil in the device. Embodiment 2

[0046] This embodiment is a further improvement of the discharge mechanism 5 on the basis of the first embodiment, so that the device can detect the water content in the box body 21 while moving the floating oil through the scraper plate 467. Once the water content is high, it will be automatically discharged to prevent the water from overflowing.

[0047] Further explanation, in order to discharge the water in the box 21, as Figure 8 As shown, the discharge mechanism 5 includes a water outlet pipe 51, a water outlet block 52 is fixedly installed on the upper side of the inner wall of the water outlet pipe 51, a sealing block 53 is provided in the inner cavity of the water outlet block 52, a movable ring 54 is fixedly installed on the arc surface of the sealing block 53, and a limiting hole is provided on the arc outer surface of the movable ring 54. When the sealing block 53 moves upward, it will drive the movable ring 54 to move upward, so that the movable ring 54 is separated from the water outlet block 52, and the sealing block 53 cannot fit with the inner wall of the water outlet block 52, so that the water in the box body 21 can be discharged through the water outlet pipe 51. The water in the box body 21 is located at the bottom, so that the water outlet pipe 51 will not discharge the oil in the box body 21;

[0048] In addition, a support frame 55 is provided on the upper side of the sealing block 53, and the support frame 55 plays a certain supporting role. A push spring 56 is provided between the sealing block 53 and the support frame 55, and the push spring 56 is supported and limited by the support frame 55, so that the push spring 56 has a downward force, which can push the sealing block 53 and the movable ring 54 to move downward. A connecting rope 57 is fixedly installed in the middle part of the upper end of the sealing block 53, and the connecting rope 57 will be wound around the surface of the take-up roller 464. When the convex plate 461 moves upward, the connecting rope 57 will be pulled to move. When the take-up roller 464 moves to the set height, the sealing block 53 and the movable ring 54 will be pulled upward through the connecting rope 57.

[0049] To further illustrate, in order to discharge a certain amount of water from the box 21, as Fig. 9As shown, the quantitative assembly 6 includes a fixed plate 61, and a movable rod 63 slidably mounted on the lower inner wall of the box body 21 is provided on the right side of the fixed plate 61. The movable rod 63 contacts the outer surface of the movable ring 54. An elastic spring 62 is fixedly installed between the fixed plate 61 and the movable rod 63. When the movable ring 54 moves upward, the movable ring 54 is limited by the movable rod 63, so that the device can continue to drain water. A fixed pulley 64 is rotatably installed in the inner cavity of the box body 21, and a connecting rope 65 is fixedly installed on the left end of the movable rod 63.

[0050] Then, the surface of the connecting rope 65 contacts the inner wall of the fixed pulley 64, and the upper horizontal end surface of the connecting rope 65 is connected to the convex plate 461. The connecting rope 65 can reduce the wear of the fixed pulley 64 when it moves, and also change the direction of the force between the convex plate 461 and the movable rod 63. When the convex plate 461 moves downward, the movable rod 63 will be pulled to the left through the connecting rope 65.

[0051] It should be noted that when the convex plate 461 moves upward with the water surface, the connecting rope 2 65 will be in a relaxed state. After enough water is released, the convex plate 461 will move downward with the water surface, and then the movable rod 63 will be pulled to the left through the connecting rope 2 65. In the initial state of the device, the connecting rope 2 65 is in a taut state, and also pulls the movable rod 63 to the left.

[0052] The specific implementation of this embodiment is as follows: when there is more water in the box body 21, the convex plate 461 will move upward with the water surface, and then the sealing block 53 and the movable ring 54 will be pulled upward by the connecting rope 57. After the sealing block 53 and the movable ring 54 move a certain distance, the movable ring 54 will be separated from the water outlet block 52. At the same time, the sealing block 53 cannot fit with the inner wall of the water outlet block 52, and the water in the box body 21 can be discharged through the water outlet pipe 51. At this time, the movable rod 63 will move to the right under the elastic force of the elastic spring 62 and enter the limiting hole on the surface of the movable ring 54, so that the movable ring 54 cannot move downward, so that the water outlet pipe 51 can continue to discharge the water in the box body 21.

[0053] When using the outlet pipe 51 to discharge water, the convex plate 461 will move downward with the water level. When the convex plate 461 moves downward with the water level, the movable rod 63 is pulled to the left through the connecting rope 65. After the movable rod 63 is disengaged from the limiting hole, the pushing spring 56 will push the movable ring 54 and the sealing block 53 to move downward, and water will no longer be discharged, so that the discharge mechanism 5 and the quantitative component 6 are restored to the initial state.

[0054] It should be noted that the specific installation method, circuit connection method and control method of the mist collector 23, the cylinder 31 and the motor 41 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0055] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
