Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and more particularly to an automobile oil-water separator component. Background Art

[0002] A car's fuel-water separator is a device used to filter water and impurities from fuel. It's primarily used in diesel vehicles, though some gasoline vehicles or those in specialized environments may also be equipped with similar components. Its core function is to protect the engine's fuel system, ensuring combustion efficiency and reducing corrosion or damage.

[0003] Diesel fuel may be mixed with water during transportation or storage, and water entering the engine will cause poor combustion of the diesel fuel and a decrease in power. Water will also corrode precision components of the diesel engine, such as the high-pressure oil pump and fuel injectors. In addition, diesel fuel contains dust and rust. Processing diesel fuel through an oil-water separator can not only separate the water, but also filter out impurities in the fuel, thereby extending the service life of the engine.

[0004] The oil-water separator works by utilizing the greater density of water than diesel, causing the water to settle at the bottom of the separator, where it is then drained through a drain valve. The separator is equipped with a multi-stage filter. Diesel fuel passes through the filter, which traps water and impurities. Some impurities remain within the filter, while others settle to the bottom of the separator and are discharged during drainage.

[0005] Currently, most oil-water separators used in diesel engines rely on manual drainage, which can only be performed when the engine is stopped. This method is not very timely. Once the water content in the separator reaches a threshold, it may affect the separation efficiency of the oil-water separator and affect the fuel efficiency of the diesel engine. Moreover, although traditional oil-water separators clearly separate oil and water, if the valve is not closed in time during the drainage process, diesel may be discharged from the drain port, resulting in diesel waste and damage to the drainage device. Therefore, it is necessary to propose an automotive oil-water separator assembly to solve the above problems. Summary of the Invention

[0006] In response to the problems existing in the prior art, the present invention aims to provide an automotive oil-water separator assembly. This assembly addresses the issues that current oil-water separator drainage devices used in diesel engines typically require manual operation, making timely drainage difficult, and that conventional oil-water separators often struggle to prevent diesel from being discharged along with the water.

[0016] As a preferred solution of the present invention, the circular array inside the annular shell has angled plates corresponding one to the release blocks, each of the angled plates is rotatably connected to the inside of the annular shell, the bottom of the angled plates is rotatably connected to a coupling head, the bottom end of the coupling head is installed with a wedge block, the top of the push head is installed with a push plate, the push plate abuts against the top of the corresponding angled plate, a second spring is also installed at the top of the push head, and the push head is elastically connected to the annular shell through the second spring.

[0017] As a preferred solution of the present invention, the inner circumferential array of the lifting plate has a plurality of side grooves, and the outer circumferential array of the lifting plate has combining cavities corresponding one to one with the combining heads.

[0018] As a preferred solution of the present invention, a debris removal cavity is provided inside the closing plate, and the debris removal cavity passes through one side of the closing plate, a sweeping plate is slidably connected in the debris removal cavity, a sliding rod is fixed to the inner end of the sweeping plate, the sliding rod is slidably connected to the corresponding sliding groove and empty groove, two changing blocks are vertically provided on the surface of the sliding rod, and a slider is provided at the far end of the closing plate, and the slider is slidably connected to the corresponding side groove.

[0019] As a preferred solution of the present invention, a plurality of sewage leakage holes are provided on the top surface of the closing plate, and the sewage leakage holes are connected to the debris removal chamber. A top frame is installed above each sewage leakage hole, and two swing plates are rotatably connected on both sides of the top frame, and the swing plates extend inside the sewage leakage hole. A limiting bar is installed in the sewage leakage hole below the swing plate, and both sides of the limiting bar abut against the swing plate. An eight-shaped plate and two triangular plates are installed in the sewage leakage hole below the limiting bar, and the two triangular plates are distributed on both sides of the eight-shaped plate.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. The present invention sets a lifting plate, a fan-shaped plate and a closing plate with a density between that of diesel and water, so that the plate is suspended at the oil-water interface, effectively separating the diesel and water layers. The lifting plate can be freely raised and lowered as the water level changes. When the water level reaches a preset height, the lifting plate is combined with the annular shell, and the linkage triggers the opening of the drain port to automatically drain the water. At the same time, the opening action of the drain port drives the closing plate to close the fan-shaped channel, so that the lifting plate forms a dynamic isolation barrier to ensure that diesel will not be mixed into the water during drainage, thus avoiding fuel waste. In addition, during the drainage process, the downward movement of the lifting plate will drive the annular shell to descend synchronously, causing the annular brush to slide along the inner wall of the outer shell, automatically cleaning the dirt deposited on the inner wall, reducing residual impurities, and maintaining the internal cleanliness of the separator, thereby extending the service life of the equipment and improving the separation efficiency.

[0022] 2. By setting up leakage holes with swing plates, figure-eight plates and triangular plates on the top surface of the closing plate, a multi-level anti-backflow sedimentation channel is constructed, so that impurities can easily slide down the inclined swing plates into the impurity removal chamber, but it is difficult for them to escape upward from the multi-level tortuous channel. At the same time, the diesel flow pressure is used to make the swing plates close to the restriction strips to maintain a stable gap. When impurities try to escape in the opposite direction, the pressure of the liquid flowing outward inside the impurity removal chamber will cause the angle of the swing plates to increase, thereby resisting the inclined surface of the triangular plate, automatically closing the gap, further blocking the backflow path, and significantly reducing the risk of impurities mixing with diesel again. When the inner rod is used to drive the closing plate to close the fan-shaped channel, the sweeping plate is first driven to swing in the impurity removal chamber, scraping the sediment in the impurity removal chamber to the opening for discharge, realizing automatic cleaning. The overall design combines efficient impurity sedimentation, dynamic backflow prevention and self-cleaning functions, greatly improving the sediment backflow prevention effect and oil-water separation efficiency.

[0039] For example 1, please refer to Figures 1 to 13 As shown, the present invention discloses an automobile oil-water separator assembly, comprising a housing 11, a drain port 21 being provided at the bottom of the housing 11, two sets of liquid guide plates 22 being symmetrically installed inside the drain port 21, and a control plate 23 being rotatably connected between the two sets of liquid guide plates 22;

[0043] A top cover 12 is installed on the top of the outer shell 11, and an oil inlet 13 and an oil outlet 14 are provided on the top surface of the top cover 12. A filter device 15 is installed inside the outer shell 11, and the top end of the inner rod 31 is rotatably connected to the bottom of the filter device 15. The top end of the outer shell 11 is provided with an inner channel 16 connected to the interior thereof. The inner bottom end of the outer shell 11 has a plurality of release blocks 17 and a plurality of positioning rods 18 in a circumferential array. The positioning rods 18 pass through the annular shell 42 and the lifting plate 61.

[0044] An adjustment slot 24 is provided on the side of the control board 23, a first bevel gear 25 is installed inside the control board 23, a motor 26 is installed outside the drain outlet 21, the output end of the motor 26 passes through the drain outlet 21, and a second bevel gear 27 is installed on the output end, and the second bevel gear 27 is meshed and connected with the first bevel gear 25.

[0045] The inner rod 31 has a plurality of sliding grooves 32 arranged in a circumferential array, and the sleeve 33 has a plurality of empty grooves 34 arranged in a circumferential array. A lower stop 35 is provided at the bottom of each empty groove 34 , and an upper stop 36 is provided at the top of each empty groove 34 .

[0046] A plurality of first springs 41 are arranged in a circular array on the inner wall of the shell 11. An annular shell 42 is slidably connected to the inside of the shell 11, and the bottom end of the first spring 41 is installed on the top surface of the annular shell 42. An annular brush 43 is provided on the outside of the annular shell 42, and the annular brush 43 contacts the inner wall of the shell 11.

[0047] The inner circumferential array of the annular shell 42 has angled plates 51 corresponding to the release blocks 17 one by one. Each angled plate 51 is rotatably connected to the inner part of the annular shell 42. The bottom of the angled plate 51 is rotatably connected to a coupling head 52. A wedge block 53 is installed at the bottom of the coupling head 52. A push plate 55 is installed at the top of the push head 54. The push plate 55 contacts the top of the corresponding angled plate 51. A second spring 57 is also installed at the top of the push head 54, and the push head 54 is elastically connected to the annular shell 42 through the second spring 57.

[0048] The lifting plate 61 has a plurality of side grooves 64 arranged in an array on the inner circumference thereof, and the lifting plate 61 has a plurality of coupling cavities 65 arranged in an array on the outer circumference thereof, each corresponding to the coupling heads 52 .

[0049] Diesel enters the housing 11 from the oil inlet 13 and enters the diesel engine from the oil outlet 14. The diesel exchanges with the filter device 15 inside the housing 11, filtering out impurities in the diesel and causing water to precipitate from the diesel and settle to the bottom of the housing 11, forming a clear separation layer between the diesel and the water.

[0050] Initially, there's no water inside the housing 11, and the lift plate 61 is at the bottom. The sealing plate 71 at the top of the lift plate 61 is also located atop each sector plate 62, exposing the sector channels 63. As more water accumulates at the bottom of the housing 11, it flows through the sector channels 63 and reaches the bottom of the lift plate 61. Leveraging the buoyancy of the water, the lift plate 61 rises as the water level rises.

[0051] In order to ensure that the lifting plate 61 and other structures on it can be suspended in the separation layer between diesel and water, the total density of the lifting plate 61 and other structures on it is between the density of water and the density of diesel, that is: water density (ρ_w≈1.0g / cm 3 )>Baffle density (ρp)>Diesel density (ρ_d≈0.83g / cm 3 ).

[0052] During the lifting process of the lifting plate 61, the lifting plate 61 slides relative to the positioning rod 18, and the sliding rod 74 protruding from the proximal end of the closing plate 71 slides in the corresponding sliding groove 32 and the empty groove 34. When the lifting plate 61 contacts the annular housing 42, the moisture inside the housing 11 reaches the maximum threshold.

[0053] As more and more water settles inside the shell 11, the lifting plate 61 gradually rises. When the lifting plate 61 approaches the annular shell 42, the top surface of the lifting plate 61 first contacts and pushes the push head 54 on the bottom surface of the annular shell 42, causing the push head 54 to slide into the inside of the annular shell 42. The push head 54 compresses the second spring 57 and drives the push plate 55 and the trigger plate 56 on its top to rise. The trigger plate 56 triggers the travel switch (not shown in the drawings) inside the annular shell 42, and the push plate 55 pushes the angle plate 51 to rotate inside the annular shell 42. During the rotation of the angle plate 51, the coupling head 52 is pushed out of the annular shell 42.

[0054] The coupling head 52 drives the wedge block 53 to move synchronously, and finally the coupling head 52 is inserted into the coupling cavity 65 outside the lifting plate 61, so that the lifting plate 61 and the annular shell 42 are combined into a whole. At this time, the wedge block 53 is at the position closest to the lifting plate 61.

[0055] After the coupling head 52 is docked with the coupling cavity 65, the travel switch inside the annular shell 42 completes the start of the motor 26, and the motor 26 immediately drives the second bevel gear 27 to rotate. The second bevel gear 27 drives the control board 23 to rotate through the first bevel gear 25. The liquid guide plate 22 inside the drain outlet 21 is crescent-shaped as a whole, with an inclined surface. Two symmetrical liquid guide plates 22 on the same horizontal plane form a group. The upper and lower groups of liquid guide plates 22 are arranged at intervals in the drain outlet 21, so that the control board 23 between the two groups of liquid guide plates 22 can rotate. After the control board 23 rotates, the drain outlet 21 is connected to the outside world, and the water settled at the bottom of the shell 11 is automatically discharged from the drain outlet 21.

[0056] The aperture opened by the control plate 23 is small enough to slow down the water flow rate and prevent the water flow rate from disturbing the diesel too quickly, thereby causing the diesel and water to mix and be accidentally discharged together with the water.

[0057] When the control plate 23 rotates, the inner rod 31 rotates synchronously. The inner rod 31 is always connected to each slide bar 74 through the slide slot 32. When the inner rod 31 rotates, the slide bar 74 is driven to swing horizontally in the empty slot 34 through the slide slot 32 (the slide bar 74 swings horizontally from one side of the corresponding empty slot 34 to the other side). The slide bar 74 drives the sweeping plate 73 to slide inside the debris removal chamber 72.

[0058] When the sweeping plate 73 slides from one side of the debris removal chamber 72 to the other side, it is blocked by the side of the closing plate 71 (the height of the opening of the debris removal chamber 72 on the side of the closing plate 71 is less than the height of the sweeping plate 73, so the sweeping plate 73 cannot escape from the debris removal chamber 72). After the sweeping plate 73 reaches the other side of the debris removal chamber 72, it drives the closing plate 71 to continue to swing, causing the slider 76 to slide in the corresponding side groove 64, and the closing plate 71 slides out from the corresponding fan-shaped plate 62, gradually closing the corresponding fan-shaped channel 63, so that the lifting plate 61 becomes a solid disc-like structure;

[0059] Lifting plate 61, sector plate 62, sealing plate 71, and annular housing 42 work together to physically separate diesel fuel from water. Throughout the drainage process, diesel fuel and water remain separated by lifting plate 61. Even after all water in housing 11 has been drained, lifting plate 61 remains at the bottom of housing 11, effectively blocking diesel fuel and preventing it from being wasted through drain port 21.

[0060] During the drainage process, the water level continues to decrease, and the lifting plate 61, which is raised by the buoyancy of the water, will also automatically drop due to the lowering of the water level. During the descent of the lifting plate 61, the annular shell 42 is driven to drop synchronously. The annular shell 42 stretches the first spring 41, and its outer annular brush 43 can brush the inner wall of the outer shell 11 to remove dirt attached to the inner wall of the outer shell 11, reduce residual impurities, and maintain the overall cleanliness of the outer shell 11 (there is often settled dirt at the bottom of the outer shell 11, which is mixed with water. Over time, some impurities may adhere to the inner wall of the outer shell 11, thereby contaminating the outer shell 11).

[0061] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 A debris removal chamber 72 is provided inside the closing plate 71, and the debris removal chamber 72 passes through one side of the closing plate 71. A sweeping plate 73 is slidably connected to the debris removal chamber 72. A sliding rod 74 is fixed to the inner end of the sweeping plate 73. The sliding rod 74 is slidably connected to the corresponding sliding groove 32 and the empty groove 34. Two changing blocks 75 are vertically provided on the surface of the sliding rod 74. A sliding block 76 is provided at the far end of the closing plate 71, and the sliding block 76 is slidably connected to the corresponding side groove 64.

[0062] A plurality of sewage holes 81 are provided on the top surface of the closing plate 71, and the sewage holes 81 are connected to the debris removal chamber 72. A top frame 82 is installed above each sewage hole 81. Two swing plates 83 are rotatably connected on both sides of the top frame 82, and the swing plates 83 extend inside the sewage hole 81. A limiting bar 84 is installed in the sewage hole 81 below the swing plate 83, and both sides of the limiting bar 84 abut against the swing plate 83. An eight-shaped plate 85 and two triangular plates 86 are installed in the sewage hole 81 below the limiting bar 84, and the two triangular plates 86 are distributed on both sides of the eight-shaped plate 85.

[0063] During the process of separating water from the diesel inside the shell 11, or during the static process, some impurities may settle from the diesel into the water. Due to the existence of the closing plate 71, some sediments may remain on the top surface of the closing plate 71 and are difficult to settle to the bottom of the shell 11 through the fan-shaped channel 63. These sediments may be mixed into the diesel again with the liquid flow during the continuous flow of diesel and the instantaneous flow of diesel inside the shell 11 when the diesel engine goes from static to starting, thereby increasing the difficulty of diesel filtration.

[0064] In order to avoid the problem that impurities settle on the top surface of the closing plate 71 and are difficult to remove and the impurities after settling are easy to flow back again, a number of drainage holes 81 are opened on the top surface of the closing plate 71, and each drainage hole 81 is respectively provided with a swinging swing plate 83 and a fixed eight-shaped plate 85 and a triangular plate 86.

[0065] Normally, each pair of swing plates 83 hangs down naturally, contacting both sides of the limiting bar 84. At this time, there is a certain gap between each swing plate 83 and the corresponding triangular plate 86, which is used for the passage of sediment. The sediment can roll along the tilted swing plate 83 to the corresponding triangular plate 86, follow the inclined surface of the triangular plate 86, roll down from the gap between it and the swing plate 83, and then roll down from the gap between the splayed plate 85 and the triangular plate 86 into the debris removal cavity 72 inside the sealing plate 71 (the positional relationship between the swing plate 83, the splayed plate 85, and the triangular plate 86 is as follows: the swing plate 83 is at the top center of the sewage leakage hole 81, the triangular plate 86 is at the bottom of the swing plate 83, and the splayed plate 85 is located between the two triangular plates 86 and slightly below. Together, the three form a tortuous sediment rolling path).

[0066] First, the tortuous path formed by the swing plate 83, the splayed plate 85 and the triangular plate 86 ensures that the sediment enters the impurity removal chamber 72 smoothly, and increases the difficulty of the sediment escaping upward, effectively reducing the possibility of the sediment being mixed with the diesel again;

[0067] Secondly, the diesel flowing above the closing plate 71 exerts downward pressure on the swing plate 83, which can make the swing plate 83 close to the limiting strip 84 (the limiting strip 84 is provided at the bottom of the swing plate 83 to ensure the angle between the two swing plates 83, thereby controlling the size of the gap between the swing plate 83 and the triangular plate 86), thereby stabilizing the size of the gap between the swing plate 83 and the triangular plate 86. Once sediment escapes from the de-waxing chamber 72, it will flow outward along with the liquid in the de-waxing chamber 72. The force of the outward flow of the liquid in the de-waxing chamber 72 causes the angle between each pair of swing plates 83 to increase. When the angle of the swing plate 83 increases, its lower hem will come into contact with the inclined surface of the triangular plate 86, thereby closing the gap between the swing plate 83 and the triangular plate 86, further preventing the sediment from escaping, and then more reliably collecting the sediment to prevent the sediment from being mixed into the diesel again.

[0068] The sediment collected in the debris removal chamber 72 still needs to be removed in time. Therefore, each time drainage begins, the inner rod 31 drives the sweeping plate 73 from one side of the debris removal chamber 72 to the side with the opening through the cooperation of the chute 32 and the slide bar 74. During the swinging process inside the debris removal chamber 72, the sweeping plate 73 can scrape the sediment toward the opening of the debris removal chamber 72, and finally scrape it out of the debris removal chamber 72 and discharge it from the corresponding fan-shaped channel 63.

[0069] When drainage is completed, the lifting plate 61 drives the annular shell 42 to descend to the bottom of the outer shell 11, and the release block 17 at the bottom of the outer shell 11 is just inserted into the inside of the annular shell 42, abutting and pushing the corresponding wedge block 53, so that the wedge block 53 drives the coupling head 52 back to the inside of the annular shell 42, and the coupling head 52 slides out of the corresponding coupling cavity 65. At the same time, the coupling head 52 drives the angle plate 51 to reverse and reset, and the upper end of the angle plate 51 pushes the push head 54 out of the annular shell 42 through the push plate 55, and drives the trigger plate 56 away from the travel switch inside the annular shell 42.

[0070] The annular housing 42 is separated from the lifting plate 61, and the annular housing 42 rises and resets under the elastic force of the first spring 41. At the same time, the motor 26 drives the second bevel gear 27 to reverse, so that the control plate 23 is reversed and the drain port 21 is closed again.

[0071] The control plate 23 drives the inner rod 31 to reverse synchronously, first driving the sweeping plate 73 back to the inner side of the debris removal chamber 72 through the cooperation of the slide groove 32 and the slide rod 74, and then using the sweeping plate 73 to resist the closing plate 71 to drive the closing plate 71 back to the top of the corresponding fan-shaped plate 62, exposing the fan-shaped channel 63 again.

[0072] During the drainage process, that is, when the lifting plate 61 descends with the water level, the sweeping plate 73 is always at the opening of the debris removal chamber 72. During this process, if sediment continues to enter the debris removal chamber 72, if the sliding rod 74 drives the sweeping plate 73 back to the inner side of the debris removal chamber 72 in the previous paragraph, the sweeping plate 73 will continue to sweep the new sediment in the debris removal chamber 72 deep into the debris removal chamber 72 and cannot be removed.

[0073] When the lifting plate 61 reaches the bottom of the shell 11, that is, when the slide rod 74 slides to the bottom of the slide groove 32 and the empty groove 34, the deflection block 75 on the surface of the slide rod 74 contacts the lower block 35 at the bottom of the corresponding empty groove 34. The lower block 35 pushes the deflection block 75 to turn and causes the slide rod 74 to rotate, thereby driving the sweeping plate 73 to rotate ninety degrees. The sweeping plate 73 is suspended in the interior of the debris removal chamber 72 and no longer plays the role of scraping sediment, so that the sweeping plate 73 will not carry sediment when returning to the inner side of the debris removal chamber 72.

[0074] Similarly, when the lifting plate 61 rises to the top of the chute 32 and the empty slot 34 as the water level rises, the corresponding turning block 75 on the slide rod 74 abuts against the upper block 36 at the top of the empty slot 34 (see the attached manual). Figure 13 As shown, the special shape of the upper block 36 can prevent the slide bar 74 from being stuck between the upper block 36 and the frame of the empty slot 34), and the upper block 36 drives the slide bar 74 to rotate through the changing block 75, and the slide bar 74 drives the sweeping plate 73 to rotate and return to the scraping state. Then, in the subsequent process of closing the fan-shaped channel 63 by the closing plate 71, the sweeping plate 73 can scrape and remove the sediment inside the miscellaneous cavity 72 again.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
