A device for separating oil and water in a scrapped vehicle

Abstract

This invention relates to the field of oil-water separation device technology, and discloses an oil-water separation device for dismantling scrapped automobiles, including a liquid collection tank. A support ring is fixedly installed in the middle of the liquid collection tank, and an inner bearing component is fixedly installed in the middle of the support ring. This oil-water separation device for dismantling scrapped automobiles, by setting an inner bearing component in the middle of the liquid collection tank, the main body of the inner bearing component is a cylinder. The outer part of the cylinder is circular, and the center is an inverted frustum-shaped hollow cylinder structure. With this structural setting of the inner bearing component, wastewater enters the frustum-shaped hollow cylinder of the cylinder and is rotated and separated. The inverted shape makes the rotation at the bottom more intense and the degree of rotation decreases as you go up. This allows large particulate impurities in the wastewater to be thrown onto the inner wall of the frustum-shaped hollow cylinder by a greater centrifugal force. As the water flows, they slide against the cylinder wall and accumulate inside the sand and gravel separation component.

Description

Technical Field

[0001] This invention relates to the field of oil-water separation device technology, specifically an oil-water separation device for dismantling scrapped automobiles. Background Technology

[0002] Dismantling end-of-life vehicles is a crucial part of vehicle lifecycle management and a key means of resource recycling. Before dismantling, petroleum-based oils or liquid synthetic lubricants such as fuel, engine oil, transmission fluid, power steering fluid, and brake fluid should be drained and stored in dedicated containers. Meanwhile, rainwater, cleaning water, and other non-domestic wastewater collected at the dismantling plant should be collected through pipelines and treated in wastewater treatment facilities to meet emission standards before being discharged. However, in actual dismantling operations, spillage and leakage are unavoidable during oil draining, and oily wastewater is generated during subsequent parts cleaning. Direct discharge of this oil-water mixture not only severely pollutes the environment but also wastes a large amount of recyclable oil resources. Therefore, oil-water separation devices are needed to separate oil and water. However, existing devices have some problems in use, as follows:

[0003] Existing wastewater from scrapped vehicles contains a large amount of large solid particles such as silt and metal. Current devices mainly use sedimentation or filtration to treat these solid particles. Natural sedimentation takes a lot of time, and the impurities that accumulate at the bottom are difficult to clean later. Treatment can only begin after all the wastewater in the device has been drained, which limits the efficiency of the device. Filtration is prone to frequent clogging, requiring constant cleaning and replacement, which also seriously affects the efficiency of the entire equipment. Therefore, we propose an oil-water separation device for scrapped vehicle dismantling. Summary of the Invention

Pull ropes are symmetrically connected on both sides in directions perpendicular to the direction of the long groove. The projection range of the pressure ring covers the top range of the sealing component. The diameter of the circular hole is larger than the diameter of the annular range covered by the upper limit protrusion of the limiting center rod. A pull rope is provided through the circular hole without contacting it. The upper end of the locking block is provided with a protruding structure.

[0015] The present invention has the following beneficial effects:

[0016] 1. This oil-water separation device for dismantling scrapped vehicles features an inner support component in the middle of the sump. The main body of the inner support component is a cylinder with an outer ring and a central inverted frustum-shaped hollow cylinder. This structure allows wastewater to enter the frustum-shaped hollow cylinder for rotational separation. The inverted shape results in vigorous rotation at the bottom, decreasing towards the top. This allows large particulate impurities in the wastewater to be thrown against the inner wall of the frustum-shaped hollow cylinder by greater centrifugal force. As the water flows, these impurities slide against the cylinder wall and accumulate inside the sand and gravel separation component. The separated water overflows from the top into the sump. This design achieves separation of particulate impurities while minimizing the flow rate of the wastewater inside the sump. The relatively slow flow allows for better natural separation of oil and water, ensuring effective subsequent oil-water separation.

[0017] 2. This oil-water separator for dismantling scrapped vehicles features a suspension assembly. When the accumulated particulate impurities inside the sand and gravel separation assembly reach a certain level, the driven components' bottom structures attract and merge, causing the suspension assembly to move downwards under the rotation of the main screw. The scraper remains inside the separation baffle, allowing the separated particulate impurities to be scraped and collected from top to bottom during this downward movement. At the final stage, the suspension assembly presses down the sealing assembly, opening the baffle and allowing all particulate impurities to be discharged into the collection cylinder. The cylinder is then closed promptly, achieving continuous and effective separation of large particulate impurities. This separator requires no downtime, significantly improving efficiency and avoiding the filter clogging problems common in traditional devices. It eliminates the need for frequent downtime for maintenance or filter replacement, further enhancing its effectiveness. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The oil-water separation device for dismantling scrapped cars involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-2An oil-water separation device for dismantling scrapped automobiles includes a liquid collection tank 1, a support ring 2 fixedly installed in the middle of the liquid collection tank 1, an inner bearing component 3 fixedly installed in the middle of the support ring 2, a sand and gravel separation component 4 movably installed in the middle of the inner bearing component 3, a support adjustment component 5 fixedly installed on the outside of the inner bearing component 3, a suspension component 6 movably installed at the bottom end of the support adjustment component 5, a driven component 7 fixedly installed at the bottom end of the suspension component 6, and a sealing component 8 movably installed inside the inner bearing component 3.

[0029] Compared with existing technologies, this application provides an inner bearing component 3 in the middle of the sludge collection tank 1. The main body of the inner bearing component 3 is a cylinder 31, with an outer ring shape and a central inverted frustum-shaped hollow cylinder structure. This structural design of the inner bearing component 3 allows wastewater to enter the frustum-shaped hollow cylinder of the cylinder 31 for rotational separation. The inverted shape results in vigorous rotation at the bottom, decreasing towards the top. This allows large particulate impurities in the wastewater to be thrown against the inner wall of the frustum-shaped hollow cylinder of the cylinder 31 by greater centrifugal force. As the water flows, these impurities slide against the cylinder wall and accumulate inside the sand and gravel separation component 4. The separated water overflows from the top into the sludge collection tank 1. This achieves the separation of particulate impurities in the wastewater while minimizing the flow rate of the wastewater inside the sludge collection tank 1. The relatively slow flow allows for better natural separation of oil and water in the wastewater, ensuring subsequent oil-water separation. The effect is achieved by using a suspension assembly 6. When the particle impurities accumulated inside the sand and gravel separation assembly 4 reach a certain level, the bottom structure of the driven assembly 7 attracts and merges with each other. Under the rotation of the bottom main screw 37, the suspension assembly 6 moves downward as a whole. The scraper 68 is always inside the separation baffle 45. During the downward movement, the particle impurities accumulated inside can be scraped down from top to bottom and collected. When the suspension assembly 6 moves to the final stage, it will press down the sealing assembly 8, thereby opening the position of the baffle 82. This allows all the particle impurities to be discharged into the collection cylinder 34 for collection. Then, it is closed in time. This completes the continuous and effective separation of large particle impurities. The separation device does not require shutdown, which greatly improves the efficiency of the device. It also avoids the problem of filter clogging in traditional devices, eliminating the need for frequent shutdowns for maintenance or filter replacement, further improving the device's performance.

[0030] Please see Figure 1-4An oil-water separation device for dismantling scrapped automobiles includes an inner support component 3, which includes a cylinder 31. A separator sleeve 32 is fixedly installed at the bottom of the cylinder 31. Limiting rods 33 are symmetrically fixedly installed on the lower surface of the separator sleeve 32. A collection cylinder 34 is movably installed at the bottom of the separator sleeve 32. A supporting screw 35 is movably installed at the bottom of the collection cylinder 34. A drive motor 36 is fixedly installed in the middle of the bottom of the collection cylinder 34. A main screw 37 is fixedly installed on the output shaft of the drive motor 36. A stirring blade 38 is uniformly fixedly installed in a ring at the bottom of the main screw 37. A water inlet pipe 39 is fixedly installed through the bottom of the cylinder 31.

[0031] In this embodiment, it should be noted that the outer part of the cylinder 31 is annular, while the center is an inverted frustum-shaped hollow cylinder structure. The separator sleeve 32 is fixedly and sealed between the annular inner part of the cylinder 31 and the outer part of the frustum-shaped hollow cylinder structure in the center. The sealing component 8 is movably sleeved on the limiting rod 33. The top end of the collecting cylinder 34 is screwed and sealed to the inner thread below the separator sleeve 32. The bottom end of the collecting cylinder 34 is provided with a threaded tube, and the threaded tube is sealed and connected to the support screw 35. The top end of the support screw 35 is abutted against and supported at the bottom end of the sealing component 8. The top end of the main screw 37 is spaced apart from the bottom end of the support adjustment component 5. The stirring blade 38 slides against the bottom end of the frustum-shaped hollow structure caused by the cylinder 31. The inner lower part of the water inlet pipe 39 is provided with an internal thread, and the upper part of the internal thread is provided with a blocking ring. A circular groove is opened at the bottom of the collecting cylinder 34. The bottom of the water inlet pipe 39 is correspondingly provided with the circular groove at the bottom of the collecting cylinder 34, and a water supply pipe is connected to it. In operation, the drive motor 36 at the bottom drives the agitator 38 to rotate, while wastewater enters the cylinder 31 through the water supply pipe and inlet pipe 39. The rotation of the agitator 38 causes the wastewater to rotate continuously, and the centrifugal force generated by the rotation throws large particles of impurities onto the inner wall of the truncated cone-shaped hollow structure of the cylinder 31, where they slide. The sand and gravel separation component 4 attached to the wall blocks and separates these large particles of impurities. When a certain amount of impurities accumulates and needs to be cleaned, the suspension component 6 at the top moves down to open the sealing component 8 at the bottom, allowing all the particles of impurities to be collected in the collection cylinder 34. The sealing component 8 is then closed, allowing the device to continue operating. Cleaning large particles of impurities simply requires opening and emptying the collection cylinder 34 and then reinstalling it. This allows the device to operate continuously and effectively, greatly improving its efficiency.

[0032] Please see Figure 2-6An oil-water separation device for dismantling scrapped cars includes a sand and gravel separation component 4. The sand and gravel separation component 4 includes a track ring 41. Multiple sliders 42 are movably arranged on the track ring 41. A linkage ring 43 is fixedly installed at the top of the slider 42. A short rod 44 is movably installed at the bottom of one side of the slider 42. A separation stop 45 is movably installed at the bottom of the short rod 44.

[0033] In this embodiment, it should be noted that the track ring 41 is fixedly installed at the top of the cylinder 31. A short rod 44 is connected to one side of the slider 42 via an extension rod, with one end of the extension rod extending into the area covered by the top of the cylinder 31. The separation baffle 45 is slidably mounted along the inner wall of the frustum-shaped hollow cylinder structure of the cylinder 31, with the width at the top being smaller than the width at the bottom. One side of the separation baffle 45 is vertically conductive, and this conductive side faces the direction of water flow rotation. Thus, under normal centrifugal force, the slider 42 will slowly rotate with the rotation of the water flow, thereby minimizing the impact of the separation baffle 45 on the water flow. When the flow becomes unstable due to the obstruction effect of the flow, the impurity particles separated from the wastewater under the action of centrifugal force are blocked and collected. This also ensures that the blocked impurity particles will not be detached from the separation baffle 45 due to the large impact of the rotating wastewater, thus ensuring the filtration and collection effect. The bottom end of the separation baffle 45 is wider, which not only ensures the separation and collection of more mud and sand impurities at the bottom during the rotational separation process, but also ensures that the bottom end of the separation baffle 45 can fully bear the subsequent downward scraping of impurities, preventing excessive impurities from overflowing, thus ensuring the effectiveness of the device.

[0034] Please see Figure 1-7 An oil-water separation device for dismantling scrapped cars includes a support and adjustment assembly 5. The support and adjustment assembly 5 includes a gantry frame 51. A base plate 52 is installed at the bottom center of the gantry frame 51. Guide frames 53 are symmetrically fixed on both sides of the gantry frame 51. Pull ropes 54 are wound around the guide frames 53. A counterweight block 55 is fixedly installed at the bottom end of the pull ropes 54. A limit center rod 56 is fixedly installed at the bottom center of the base plate 52.

[0035] In this embodiment, it should be noted that the bottom end of the gantry frame 51 is fixedly installed outside the cylinder 31. Guide wheels are provided at both ends of the guide frame 53. Adjacent guide wheels of the symmetrically arranged guide frames 53 on both sides are symmetrically spaced at the center. The outer guide wheel extends laterally beyond the area covered by the inner bearing assembly 3 and is located within the liquid accumulation tank 1. The other end of the pull rope 54 is fixedly connected to the top of the base plate 52. A limiting protrusion is provided on the outer side of the limiting center rod 56. The suspension assembly 6 slides on the limiting center rod 56. Thus, during the downward movement of the suspension assembly 6, the presence of the counterweight 55 and... The upper limit protrusion on the limiting center rod 56 limits the base plate 52, ensuring the stable downward movement of the suspension assembly 6 and thus completing the scraping and cleaning of large particles of impurities. Furthermore, the counterweight 55 is always located in the wastewater inside the liquid accumulation tank 1. After the magnetic attraction effect is released at the bottom of the driven assembly 7, the weight of the counterweight 55 allows the suspension assembly 6 and the driven assembly 7 to move upward as a whole. The buoyancy of the wastewater on the counterweight 55 prevents the structure from being damaged by a collision due to rapid upward movement. Instead, the buoyancy allows the entire structure to move upward and return to its original position slowly and stably, ensuring the effectiveness of the separation device.

[0036] Please see Figure 4-8 An oil-water separation device for dismantling scrapped automobiles includes a suspension assembly 6. The suspension assembly 6 includes a disc 61. The edge of the disc 61 is uniformly provided with side grooves 62. A pressure ring 63 is fixedly installed on the outer ring of the disc 61. A circular hole 64 is provided in the middle of the disc 61. Long grooves 65 are symmetrically provided on both sides of the circular hole 64 in the middle of the disc 61. A locking block 66 is movably installed inside the long groove 65. A straight rod 67 is rotatably installed inside the side groove 62. A scraper 68 is movably installed at the bottom end of the straight rod 67.

[0037] In this embodiment, it should be noted that a connecting bearing is provided inside the bottom end of the base plate 52. The center of the bearing is fixedly connected to the top center of the disc 61 through a hollow tube. Pull ropes 54 are symmetrically connected on both sides in directions perpendicular to the direction of the long groove 65. The projection range of the pressure ring 63 covers the top range of the sealing component 8. The diameter of the circular hole 64 is larger than the diameter of the annular range covered by the upper limit protrusion of the limiting center rod 56. The pull rope 54 is provided through the circular hole 64 without contacting it. The upper end of the locking block 66 is provided with a protruding structure. This structure is separated from the lower surface of the base plate 52 when the bottom driven component 7 is not adsorbed. After being adsorbed and pulled and rotated, it is tightly attached to the lower surface of the base plate 52. The attached structure is provided with a rubber pad to increase friction. The straight rod 67 is in a vertically downward state. The scraper 68 and the bottom end of the straight rod 67 are connected. The device features a hinged connection and a scraper at the bottom. This scraper is always positioned inside the separating baffle 45, with one end fitting against the inner side of the separating baffle 45. In the non-scraping state, the locking block 66 is separated from the bottom of the base plate 52. Under the rotation of the water flow below, the disc 61 can be rotated, causing the scraper 68 connected at the bottom to rotate synchronously with the rotation of the separating baffle 45. This ensures that the scraper 68 is always positioned at the top of the separating baffle 45. When scraping is required, the structure on the driven component 7 can be used to drive the suspension component 6 and the driven component 7 to move downwards as a whole via the main screw 37, thereby scraping away the impurities inside the separating baffle 45. Upon reaching the bottom, the pressure ring 63 presses down on the top of the sealing component 8 to automatically open the bottom drainage channel for the discharge of large particles, demonstrating the linkage effect of the device.

[0038] Please see Figure 7-8 An oil-water separation device for dismantling scrapped automobiles includes a driven assembly 7, which includes a suspension rod 71. A crossbar 72 is fixedly installed on one side of the bottom end of the suspension rod 71. A support head 73 is movably installed on the crossbar 72. A vertical plate 74 is fixedly installed above the support head 73. A guide wheel 75 is movably installed on one side of the bottom of the suspension rod 71. A traction rope 76 is fixedly installed on the vertical plate 74. A threaded sleeve 77 is fixedly installed on the support head 73.

[0039] In this embodiment, it should be noted that the top of the suspension rod 71 is fixedly installed on the lower surface of the disc 61. One end of the crossbar 72 is provided with an elastic pull rope and is fixedly connected to the inside of the support head 73. The support heads 73 are arranged in pairs, and electromagnets are provided inside the opposite sides. The traction rope 76 is wound around the guide wheel 75 and is connected to guide rotation. The other end is fixedly installed to the bottom end of the locking block 66. The support heads 73 are separated when the internal electromagnets are not energized to generate magnetic force. Thus, when it is necessary to perform the scraping operation of impurity particles inside the separation baffle 45, it is only necessary to connect the support head 73 to the control bar. When the electromagnet inside head 73 is powered, the support heads 73 on both sides can attract and adhere to each other, thereby connecting the two threaded sleeves 77 to the top of the main screw 37. Under the rotation of the main screw 37, the driven component 7 can be moved downward as a whole, which in turn causes the scraper 68 to move downward in the separation stop 45 to scrape off the impurity particles. After scraping is completed, the two threaded sleeves 77 can be separated by disconnecting the power supply. Under the weight of the side counterweight 55, the overall structure moves upward automatically, demonstrating the structural linkage and automation of the device.

[0040] Please see Figure 1-5 An oil-water separation device for dismantling scrapped cars includes a sealing assembly 8. The sealing assembly 8 includes a base ring 81. Multiple baffles 82 are uniformly fixedly installed on the upper surface of the base ring 81 in a ring. Multiple side rods 83 are uniformly fixedly installed on the side of the base ring 81 in a ring. A vertical rod 84 is installed at the top of one end of the side rod 83. A through groove 85 is opened on the side rod 83.

[0041] In this embodiment, it should be noted that the base ring 81 is fitted to the bottom end of the cylinder 31, and the bottom end of the cylinder 31 is provided with multiple discharge grooves in an annular shape. The baffle 82 is sealed and connected to the discharge grooves. The top end of the upright rod 84 extends above the sand and gravel separation component 4, and the upright rod 84 and the cylinder 31 are damped and slidably connected. In this way, when discharging impurity particles, the support screw 35 is first turned to move it down and away from the bottom end of the base ring 81. The suspension component 6 that moves down will press down on the top end of the upright rod 84, so that the baffle 82 will open the discharge groove position and collect the scraped particle impurities into the collection cylinder 34. After collection, the support screw 35 is turned up again to move it up, and the sealing component 8 is moved upward and returned to its original position, ensuring the continuous use effect of the entire device.

[0042] Working principle: An external water supply device injects wastewater into the cylinder 31 through the inlet pipe 39. The drive motor 36 at the bottom drives the main screw 37 and the agitator 38 to rotate. The rotation of the agitator 38 causes the wastewater to rotate continuously, generating centrifugal force. Under the action of centrifugal force, large particles and metal impurities are separated and adhered to the inner wall of the frustum-shaped hollow cylinder structure of the cylinder 31, sliding together. The separation baffle 45, which is attached to the inside of the cylinder 31, also rotates along with the rotation of the water flow. The separated large particles accumulate inside the separation baffle 45. When it is necessary to clean and scrape off the accumulated particles, the power inside the support head 73 is turned on, causing a magnetic attraction between the two support heads 73. This causes the two threaded sleeves 77 to clamp onto the top of the main screw 37 and connect threadedly. Under the action of the rotation of the main screw 37, the suspension assembly 6 and the driven assembly 7 move down as a whole, while the bottom support screw... Tighten the bottom end of the base ring 81. When the pressure ring 63 moves down to the top of the upright 84, it will move down, which will cause the baffle 82 to open the discharge groove at the bottom of the cylinder 31, and discharge the particulate impurities into the collection cylinder 34 for collection. After scraping, disconnect the power supply of the electromagnet inside the support head 73. Under the action of the elastic rope, the two support heads 73 will drive the threaded sleeve 77 to separate. Under the weight of the counterweight 55 set on the side, the suspension component 6 and the driven component 7 will move up automatically. Since the counterweight 55 is placed in the wastewater, the buoyancy of the wastewater will make the overall structure move up slowly and stably until the structure returns to its position. At the same time, the support screw 35 will be tightened back to the bottom end of the support base ring 81. The relatively stable water flow at the top of the cylinder 31 will also effectively separate the oil and water under the action of centrifugal force and flow into the liquid accumulation tank 1 by overflowing to the outside, which will facilitate the subsequent separation of the oil.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
