Description

Technical Field

[0001] This invention relates to the field of lubricating oil filtration technology, specifically to a cyclone separator for removing impurities from waste lubricating oil. Background Technology

[0002] Lubricating oil is a liquid used in the transmission of mechanical parts to reduce friction, cool and prevent rust. It is widely used. However, with prolonged use, lubricating oil can easily mix with particles from the wear of mechanical parts or externally dispersed impurities. Separating these impurities facilitates subsequent reprocessing.

[0003] Citing the Chinese patent with announcement number "CN220696099U", the separation tank body has a connecting tank movably connected to its top, and the top of the connecting tank is connected to an air supply tank; by setting a piston, in conjunction with the air pump and the air supply pipe, after the oil supply operation is completed, the connecting tank, the air supply tank and the extension tank are displaced, and the residual lubricating oil in the air supply tank is pushed down.

[0004] When existing devices pour lubricating oil into the separation unit, the lubricating oil directly hits the surface of the filter screen or filter plate, causing some impurities to pass through the mesh and enter the clean oil zone without being filtered out. This affects the separation efficiency of the device. In some cases, prolonged pouring can cause impurities to accumulate in the central area of ​​the filter screen or filter plate, forming a mushroom-shaped thick filter cake, which further affects the separation efficiency of the lubricating oil.

[0017] This invention provides a cyclone separator for removing impurities from waste lubricating oil. It has the following beneficial effects: 1. This cyclone separator for removing impurities from waste lubricating oil features a separation plate and a solenoid valve for on / off control. The lubricating oil is directed through corresponding pipes as the separation plate rotates to different positions, preventing direct impact on the filter plate surface. A second arc-shaped fixing block guides a portion of the lubricating oil along the separation plate to the top of the second arc-shaped fixing block, where it is evenly distributed into the separation chamber, facilitating subsequent filtration. Furthermore, a first, second, and third filter plate of decreasing height are positioned on top of the second arc-shaped fixing block. This prevents obstruction of the lubricating oil's normal flow while initially filtering out some impurities, reducing the filtration pressure on subsequent filter plates and improving the overall impurity separation efficiency. With the first fixing block, when the separation plate is perpendicular to the ground, direct impact on the filter plate is prevented, ensuring a uniform flow of lubricating oil into the separation chamber and improving the device's separation efficiency.

[0018] 2. This cyclone separator for removing impurities from waste lubricating oil features an arc-shaped sliding rod. A portion of the lubricating oil falls onto the top of an arc-shaped storage plate. When the lubricating oil on the top of the arc-shaped storage plate reaches a certain amount, the plate tilts to one side, thus evenly guiding the falling lubricating oil to the top of the fourth filter plate. This prevents a large amount of lubricating oil from impacting only a portion of the filter plate, maximizing the filter plate's impurity filtration effect and efficiency. Furthermore, counterweights are installed at the bottom of both sides of the arc-shaped storage plate. When the plate initially tilts, the counterweights accelerate the tilting speed, preventing lubricating oil residue on the top of the plate and ensuring the overall efficiency of the device in separating lubricating oil.

[0019] 3. This cyclone separator for removing impurities from waste lubricating oil uses a cylindrical toothed block. A second drive motor moves the cylindrical toothed block back and forth, causing the support frame to vibrate continuously. The vibration of the fourth filter plate further disperses the vertically injected lubricating oil, forcing it to diffuse laterally on the surface of the fourth filter plate. Simultaneously, the vibration of the fourth filter plate effectively breaks down the bubble film in the lubricating oil, eliminating bubble blockage on the surface of the fourth filter plate, thereby improving filtration efficiency. Combined with the movement of the first scraper, it effectively prevents impurities from agglomerating and accumulating, allowing them to quickly fall into the interior of the arc-shaped filter plate, thus improving the efficiency of the device in separating lubricating oil.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0024] Example 1: Please refer to Figure 1-7 The present invention provides a technical solution: a cyclone separator for removing impurities from waste lubricating oil, comprising a separation box 1, a separation top box 2 fixedly connected to the top of the separation box 1, a diversion mechanism 3 fixedly connected to the surface of the separation top box 2, a vibration mechanism 4 fixedly connected to the surface of the separation box 1, and an impurity cleaning mechanism 5 fixedly connected to the surface of the separation box 1.

The second arc-shaped fixing block 39 is slidably connected to a slide rod 311. The surface of the slide rod 311 is fixedly connected to a second fixing block 310. The inside of the second fixing block 310 is rotatably connected to a roller 312.

[0025] Vibration mechanism 4 includes: The support frame 47 is slidably connected inside the separation box 1, and the surface of the support frame 47 is fixedly connected to the buffer oil distribution mechanism 6.

[0026] The diversion mechanism 3 also includes a first drive motor 31, which is fixedly connected to the surface of the separation top box 2. The separation plate 32 is rotatably connected to the inside of the separation top box 2. The inside of the first drive motor 31 is fixedly connected to the separation plate 32 through the output shaft. A first pipe 33 is fixedly connected to the top of the separation top box 2. A second pipe 34 is fixedly connected to the top of the first pipe 33. A solenoid valve 35 is fixedly connected to the surface of the second pipe 34.

[0027] There are four second arc-shaped fixing blocks 39, which are symmetrically distributed in pairs on both sides of the separation plate 32. The interior of the second arc-shaped fixing block 39 is provided with a through groove. The surface of the second arc-shaped fixing block 39 is fixedly connected to the first filter plate 313, the second filter plate 31301 and the third filter plate 31302, and the height of the three decreases in the order of the first filter plate 313, the second filter plate 31301 and the third filter plate 31302. The surface of the second arc-shaped fixing block 39 is fixedly connected to the first collection box 314.

[0028] The separation plate 32 is rotatably connected to a first fixing block 36. The two sides of the first fixing block 36 are fixedly connected to a first arc-shaped fixing block 37. The first arc-shaped fixing block 37 has a through hole inside, and a rotating round block 38 is rotatably connected inside the through hole of the first arc-shaped fixing block 37. The separation top box 2 is fixedly connected to a rounded corner fixing block 315, and there are four rounded corner fixing blocks 315.

[0029] The buffer oil distribution mechanism 6 includes a fifth fixing block 64, which is fixedly connected to the surface of the support frame 47. A fourth fixing block 62 is fixedly connected to the top of the fifth fixing block 64. An arc-shaped slide rod 63 is slidably connected inside the fourth fixing block 62. An arc-shaped storage plate 61 is fixedly connected to the surface of the arc-shaped slide rod 63, and the arc-shaped storage plate 61 is rotatably connected to the fourth fixing block 62. A counterweight block 65 is symmetrically fixedly connected to the bottom of the arc-shaped storage plate 61.

[0030] In use, firstly, lubricating oil is injected into the interior of the separation top box 2 through the second pipe 34, and then the first drive motor 31 is started to drive the separation plate 32 as follows. Figure 3As shown, when rotating clockwise, the solenoid valve 35 controls the injected lubricating oil to flow into the left side of the first pipe 33. Similarly, when the first drive motor 31 starts and drives the separating plate 32 to rotate in the opposite direction, and the separating plate 32 continues to rotate towards the right side of the first pipe 33 while perpendicular to the ground, the solenoid valve 35 controls the injected lubricating oil to flow into the right side of the first pipe 33. During the reciprocating rotation of the separating plate 32, when the separating plate 32 rotates to the left side of the first pipe 33, the first fixing block 36 rotates counterclockwise inside the separating plate 32. When the separating plate 32 rotates to the vertical position, the first fixing block 36 is also perpendicular to the ground. At this time, some lubricating oil flows directly to the position of the first arc-shaped fixing block 37. Under the action of the rotating circular block 38, the lubricating oil is further diverted, preventing the lubricating oil from vertically spraying into the surface of the filter plate. When the separating plate 32 rotates to the right side of the first pipe 33, the first fixing block 36 rotates counterclockwise inside the separating plate 32. Block 36 rotates clockwise inside the separating plate 32, ensuring that the injected lubricating oil flows evenly into the separating chamber 1. During the reciprocating rotation of the separating plate 32, the roller 312, under the restriction of the rounded corner fixing block 315, pushes the second fixing block 310 to move towards the direction of the first collection chamber 314, thereby cleaning the impurities on the top of the second arc-shaped fixing block 39 and collecting them inside the first collection chamber 314. Then, the slide bar 311 returns to its original position under the action of the cylindrical spring on its surface. After that, part of the lubricating oil flows directly to the top of the fourth filter plate 48, and part of the lubricating oil flows to the top of the arc-shaped storage plate 61. When the lubricating oil on the top of the arc-shaped storage plate 61 reaches the set amount, under the action of the counterweight block 65, the arc-shaped storage plate 61 quickly tilts to one side, thereby continuously compressing the arc-shaped spring connected to the surface of the arc-shaped slide bar 63. Then, all the lubricating oil on the top of the arc-shaped storage plate 61 flows evenly to the top of the fourth filter plate 48, which is convenient for subsequent filtration.

[0031] By setting a separation plate 32 and coordinating with the on / off control of the solenoid valve 35, lubricating oil is introduced through corresponding pipes when the separation plate 32 rotates to different positions, avoiding direct impact of lubricating oil on the filter plate surface. A second arc-shaped fixing block 39 is also provided, guiding a portion of the lubricating oil along the separation plate 32 to the top of the second arc-shaped fixing block 39. Under the guidance of the second arc-shaped fixing block 39, the oil is evenly distributed into the interior of the separation chamber 1, facilitating subsequent filter plate filtration. Furthermore, a first filter plate 313, a second filter plate 31301, and a third filter plate 31302 with progressively decreasing heights are set on the top of the second arc-shaped fixing block 39. This avoids obstructing the normal flow of lubricating oil while initially filtering out some impurities, reducing the filtration pressure on subsequent filter plates and improving the overall impurity separation effect of the device. With the first fixing block 36, when the separation plate 32 is perpendicular to the ground, direct impact of lubricating oil on the filter plates is avoided, thus ensuring that the lubricating oil flows evenly into the interior of the separation chamber 1, improving the separation efficiency of the device.

[0032] Example 2: Please refer to Figure 1-11 Based on Embodiment 1, the present invention provides a technical solution: The vibration mechanism 4 includes a third fixed block 42, which is fixedly connected to the surface of the separation box 1. A second drive motor 41 is fixedly connected to the surface of the third fixed block 42. A rotating disk 43 is fixedly connected inside the second drive motor 41 through an output shaft. A rotating toothed block 44 is rotatably connected to the surface of the third fixed block 42, and the rotating toothed block 44 is slidably connected to the rotating disk 43. A cylindrical toothed block 45 is meshed with the surface of the rotating toothed block 44.

[0033] The surface of the support frame 47 is slidably connected to a limiting slide rod 46, and the limiting slide rod 46 is fixedly connected to the inner wall of the separation box 1. The support frame 47 is internally fixedly connected to a fourth filter plate 48, and there are two fourth filter plates 48.

[0034] The impurity cleaning mechanism 5 includes a first electric push rod motor 51. The first electric push rod motor 51 is fixedly connected to a first scraper 52 through an output shaft. The first scraper 52 is slidably connected to a support frame 47. A rectangular toothed block 54 is fixedly connected to the inside of the support frame 47. A slider 510 is slidably connected to the surface of the separation box 1, and the first electric push rod motor 51 is fixedly connected to the surface of the slider 510.

[0035] A cleaning rod 55 is rotatably connected to the surface of the first scraper 52, and a cylindrical gear 53 is fixedly connected to the surface of the cleaning rod 55, and the cylindrical gear 53 meshes with the rectangular tooth block 54.

[0036] An arc-shaped filter plate 59 is fixedly connected inside the support frame 47, and the arc-shaped filter plate 59 is fixedly connected to the fourth filter plate 48. A second collection box 58 is fixedly connected symmetrically to the surface of the arc-shaped filter plate 59. A third drive motor 56 is fixedly connected inside the support frame 47. A second scraper 57 is fixedly connected inside the third drive motor 56 through the output shaft.

[0037] In use, the second drive motor 41 is started, which drives the rotating disk 43 to rotate via the output shaft. The rotation of the rotating disk 43 drives the rotating gear block 44 to move back and forth. The reciprocating movement of the rotating gear block 44 also drives the cylindrical gear block 45 to move. The movement of the cylindrical gear block 45 drives the fourth filter plate 48 to vibrate continuously via the support frame 47. Then, the first electric push rod motor 51 is started, which drives the first scraper 52 to move along the surface of the fourth filter plate 48 to the bottom position of the fourth filter plate 48 via the output shaft. During the movement of the first scraper 52, the cylindrical gear 53 rotates under the action of the rectangular gear block 54, thereby driving the cleaning rod 55 to rotate and clean. Finally, the impurities are cleaned into the interior of the arc-shaped filter plate 59. Then, the third drive motor 56 is started, which drives the second scraper 57 to rotate slowly via the output shaft, thereby scraping the impurities inside the arc-shaped filter plate 59 into the interior of the second collection box 58 for collection. The lubricating oil filtered by the fourth filter plate 48 finally falls to the bottom of the separation box 1 for convenient subsequent use.

[0038] By setting up the arc-shaped slide bar 63, some of the lubricating oil falls on the top of the arc-shaped storage plate 61. When the lubricating oil on the top of the arc-shaped storage plate 61 reaches a certain amount, the arc-shaped storage plate 61 tilts to one side, thereby guiding the directly falling lubricating oil evenly to the top of the fourth filter plate 48. This avoids a large amount of lubricating oil only impacting a part of the filter plate, maximizing the filtering effect and efficiency of the filter plate. Furthermore, counterweights 65 are set at the bottom of both sides of the arc-shaped storage plate 61. When the arc-shaped storage plate 61 is initially tilted, the counterweights 65 accelerate the tilting speed of the arc-shaped storage plate 61, and prevent lubricating oil residue on the top of the arc-shaped storage plate 61, ensuring the overall efficiency of the device in separating lubricating oil.

[0039] By setting the cylindrical toothed block 45, the second drive motor 41 is started, which ultimately drives the cylindrical toothed block 45 to move back and forth, thereby causing the support frame 47 to vibrate continuously. The vibration of the fourth filter plate 48 further disperses the vertically injected lubricating oil, forcing the lubricating oil to spread laterally on the surface of the fourth filter plate 48. At the same time, the vibration of the fourth filter plate 48 effectively destroys the bubble film in the lubricating oil and eliminates the bubble blockage on the surface of the fourth filter plate 48, thereby improving the filtration efficiency. Combined with the movement of the first scraper 52, it effectively avoids the accumulation of impurities, allowing the impurities to fall quickly into the interior of the arc-shaped filter plate 59, thereby improving the efficiency of the device in separating lubricating oil.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
