Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation, and in particular to an oil-water separation system. Background Art

[0002] In the field of oil processing, the oil-water separation system is a crucial technology. It is mainly used to treat the oil-water mixture produced during oil extraction and refining. If the oil-water mixture produced during oil processing is directly discharged without effective treatment, it will cause serious pollution to the environment, including water pollution and soil pollution. The oil-water separation system can separate the oil and water in these mixtures, thereby reducing the negative impact on the environment. The separated oil can be recycled, which not only helps to reduce resource waste, but also reduces production costs. The existing technology has poor efficiency in oil-water separation and requires a long time to completely separate.

[0003] For example, an oil-water separation system provided by authorization announcement number CN118684307B gathers the oil film on the water surface in the separation tank and brings it close to the oil pumping port, thereby reducing the water content in the oil film extracted from the oil pumping port and greatly improving the effect of oil-water separation. At the same time, a receiving tank is provided to separate solid impurities in the oil-water mixture to avoid blockage of the oil pumping port. The solid impurities in the oil-water mixture are intercepted in the receiving tank. When the transmission belt drives the receiving tank to move in the separation tank, the sieve holes on the side wall of the receiving tank allow water in the separation tank to pass through, thereby flushing the solid impurities and washing out the oil film in the solid impurities. The oil film floats on the water surface. When another receiving tank enters the separation tank and moves in a direction close to the floating ball, that is, moves in a first direction, a scraper on the receiving tank enters the separation tank, and the lower part of the scraper is immersed in the separation tank. The receiving tank moves in the first direction to scrape the oil film, thereby gathering the oil film near the floating ball, increasing the thickness of the oil film near the floating ball, and the oil pumping pipe on the floating ball extracts the oil film.

[0004] It has major disadvantages: the oil film is gathered by the movement of the scraper, but since the widths of both ends of the separation tank are consistent, after the scraper moves from one end to the other to gather the oil film; due to the existence of the oil outlet pipe, there is a gap between the scraper and the other end of the separation tank, a large amount of oil is gathered here and cannot flow out from the oil outlet pipe in the shortest time; at the same time, a large amount of impurities accumulate in the holding tank, which is inconvenient to clean the holding tank when cleaning is needed. Summary of the invention

[0005] The embodiment of the present application provides an oil-water separation system, which solves the problem of gathering oil film by moving the scraper in the prior art. However, since the widths of the two ends of the separation tank are the same, after the scraper moves from one end to the other end to gather the oil film, due to the existence of the oil outlet pipe, a gap is left between the scraper and the other end of the separation tank, and a large amount of oil is gathered here and cannot flow out from the oil outlet pipe in the shortest time. At the same time, a large amount of impurities accumulate in the receiving tank, which is inconvenient to clean the receiving tank when it needs to be cleaned, so that the internal cavity cross-section of the separation tank is changed to an isosceles trapezoid, the oil outlet pipe is located at the narrowest point, and retractable retractable plates are arranged at both ends of the scraper. The scraper and the retractable plates move from the widest point to the narrowest point. The retractable plates continuously shrink to adapt to the shape of the separation tank and intercept the oil film. The range of the oil film will continue to shrink and narrow, thereby improving the collection effect of the oil outlet pipe. The retractable retractable plates can scrape off the oil attached to the surface when they shrink, reduce the contact area between the scraper and the oil film, and reduce the oil attached when the scraper and the retractable plates rise. In addition, the filter box can be disassembled for easy cleaning.

[0016] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: First, the internal cavity cross-section of the separation tank is changed into an isosceles trapezoid, the oil outlet pipe is located at the narrowest point, and retractable telescopic plates are set at both ends of the scraper. The scraper and the telescopic plate move from the widest to the narrowest point. The telescopic plate continuously shrinks to adapt to the shape of the separation tank and intercepts the oil film. The range of the oil film will continue to shrink and narrow, thereby improving the collection effect of the oil outlet pipe; the retractable telescopic plate can scrape off the oil attached to the surface when it shrinks, reduce the contact area between the scraper and the telescopic plate, and reduce the oil attached when the scraper and the telescopic plate rise; and the filter box can be disassembled for easy cleaning; Second, add an air bag. The air bag is located in the forward direction of the scraper. During the expansion and contraction of the air bag, it can shake the oil film, which can increase the speed of its entry into the lifting pipe and the amount of oil film collected. When the air bag is closest to the lifting pipe, it can drive the oil film near the lifting pipe to shake, and shake the part around the lifting pipe that the scraper cannot reach, so as to shake the oil film on the surface into the lifting pipe, thereby improving the efficiency of oil film collection. Thirdly, after the airbags are divided into multiple parts, the amount of air required to inflate the airbags to a certain extent and contact the oil film will also be reduced. At the same inflation speed, the frequency of expansion and contraction increases, which improves the shaking and collecting effect of the oil film. The airbags located at the oil surface are inflated separately to reduce the shaking of water, thereby reducing the amount of water entering the oil outlet pipe and improving the collection effect of the oil film. At the same time, multiple airbags are arranged in sequence from top to bottom to adapt to different oil surface heights, further improving the collection effect of the oil film. Fourthly, the intercepting rope can intercept the oil film remaining in front of the scraper, collect it, and drip it into the separation tank and the lifting pipe. When the scraper and the telescopic plate do not conflict with the intercepting rope, the gravity of the oil gathers in the middle section of the intercepting rope and drips into the lifting pipe, thereby improving the collection effect. At the same time, the deformed intercepting rope can slow down the ejection speed of the telescopic plates, reduce the splashing degree of the oil attached to the scraper, and further improve the collection effect of the oil film.

The two conveyor belts 170 are symmetrically arranged. The conveyor belt 170 is located between the two brackets 180. One side of the conveyor belt 170 is arranged on the side where the two brackets 180 are close to each other. The conveyor belt 170 is located on the inner circle of the groove slideway 181 of the annular structure. When the conveyor belt 170 is working, it drives the scraper 310 to extend into the separation tank 112 from the widest part; The ultrasonic thickness gauge 190 is used to detect the thickness of the oil film.

One end of the telescopic rod 340 away from the first fixing plate 330 is fixed to the second fixing plate 360. The spring 350 is sleeved on the telescopic rod 340, and the two ends of the spring 350 are respectively fixed to the first fixing plate 330 and the second fixing plate 360. The telescopic direction of the telescopic rod 340 is parallel to the axis of the connecting rod 210; The interception assembly 300 further includes a filter box 370, a water outlet 371, a feed outlet 372, a filter screen 380 and a cover plate 390; The filter box 370 is detachably arranged on the lower side of the scraper 310, and one side of the filter box 370 is provided with a water inlet 371, and the water inlet 371 passes through the filter box 370, and the penetration direction of the water inlet 371 is parallel to the forward direction of the scraper 310. The filter box 370 is provided with a discharge port 372, and the discharge port 372 is connected with the water inlet 371, and a cover plate 390 is detachably arranged in the discharge port 372; The filter box 370 is used to filter the oil-water mixture and store the filtered solid impurities, so as to facilitate flushing the oil film on the surface when the filter box 370 moves forward in the separation tank 112; There are two filter screens 380, which are fixed at both ends of the water outlet 371. The mesh size of the filter screen 380 is smaller than the solid impurities in the oil-water mixture. After the scraper 310 extends into the separation tank 112 , a gap is left between the lower end of the filter screen 380 and the bottom side of the separation tank 112 .

[0023] During the use of the device, the filter box 370 is installed under the scraper 310, the cover 390 is opened, and the mixture of oil and water to be filtered is poured into the filter box 370. The water and oil are filtered through the filter net 380 and enter the separation tank 112. Solid impurities remain in the filter box 370. The oil in the mixture floats on the surface of the water and spreads to the entire water surface of the separation tank 112. The thickness of the oil film is detected by the ultrasonic thickness gauge 190, and the height of the lifting tube 140 is adjusted in real time by the electric slide 120. When the oil film is gathered, the conveyor belt 170 works, and the electromagnet 160 is started, so that the scraper 310 extends into the separation tank 112. Due to the adsorption of the electromagnet 160 below, the scraper 310 always maintains a vertical state. In the process of continuously driving the scraper 310 to move, the telescopic plates 320 at both ends of the scraper 310 contact the inner wall of the separation tank 112, intercept the oil film in front of the scraper 310, gather it, and prevent it from flowing back. In the process of continuously moving forward, the length of the telescopic plate 320 is continuously reduced, and it is squeezed by the inner wall of the separation tank 112 and retracted into the sliding port 311 to adapt to the separation tank 112 with a changing width, and the range of movement of the oil film is continuously reduced. , pushing the oil film into the lifting pipe 140; when the conveyor belt 170 drives the scraper 310 to rise, and the telescopic plates 320 at both ends of the scraper 310 do not conflict with the inner wall of the separation tank 112, the telescopic plates 320 are reset by the elastic force of the telescopic rod 340 and the spring 350, and because the rotating column 230 is rotatably connected with the sliding column 220, and the lower end of the scraper 310 is adsorbed by the electromagnet 160, the scraper 310 is always conveyed vertically downward; and in the process of the scraper 310 moving forward, the oil film in the solid impurities in the filter box 370 is continuously flushed by the water flow, so that the oil film can float to the surface of the water, and then the oil film can float to the surface of the water. The conveyor belt 170 continuously drives the two connecting components 200 and the intercepting component 300 to work reciprocatingly to gather the internal oil film; when the oil film is thick, the scraper 310 is closest to the lifting tube 140 and the height has not risen, the conveyor belt 170 can be controlled to stop working until the oil film completely flows out of the lifting tube 140, and then the conveyor belt 170 is started; after the oil film is collected, the filter box 370 can be disassembled to clean the solid impurities inside it to facilitate the next oil film collection; and the excess water inside can be discharged through the drain port on one side of the separation tank 112.

[0024] Compared with the prior art, the internal cavity cross-section of the separation tank 112 is changed into an isosceles trapezoid, the oil outlet pipe 150 is located at the narrowest point, and retractable telescopic plates 320 are arranged at both ends of the scraper 310. The scraper 310 and the telescopic plate 320 move from the widest point to the narrowest point. The telescopic plate 320 continuously shrinks to adapt to the shape of the separation tank 112 and intercepts the oil film. The range of the oil film will continue to shrink and narrow, thereby improving the collection effect of the oil outlet pipe 150; the retractable telescopic plate 320 can scrape off the oil attached to the surface when shrinking, reduce the contact area between the scraper 310 and the telescopic plate 320, and reduce the oil attached when the scraper 310 and the telescopic plate 320 rise; and the filter box 370 can be disassembled for easy cleaning.

[0025] Embodiment 2: When the embodiment 1 is in use, the scraper 310 intercepts the accumulated oil film and collects it. However, when the accumulated oil film is thick, the scraper 310 needs to stop working for a long time, which makes the working efficiency worse. In addition, there are places around the lifting tube 140 and the inner wall of the separation tank 112 that the scraper 310 cannot reach, resulting in the inability to scrape the surface oil film into the lifting tube 140 through the scraper 310. Based on this, the solution of the embodiment 1 is improved, such as Fig.13 As shown: Also included is an expansion assembly 400, wherein the expansion assembly 400 includes an air bag 410 and an air pump 420; The airbag 410 is fixed on one side of the scraper 310, and the airbag 410 is located in the forward direction of the scraper 310 in the separation tank 112, and the air pump 420 is fixed on the side of the scraper 310 away from the airbag 410; When the scraper 310 extends into the separation tank 112, the air pump 420 is always located above the liquid surface; The output end of the air pump 420 is communicated with the air bag 410 .

[0026] When the scraper 310 moves in the water and oil film, the air bag 410 can be inflated by the air pump 420 to drive the oil film on the surface to shake, thereby increasing the speed at which the oil film enters the lifting tube 140 and the amount of oil film collected. When the scraper 310 is closest to the lifting tube 140, the expansion and contraction of the air bag 410 can drive the nearby oil film to shake, thereby shaking the part around the lifting tube 140 that the scraper 310 cannot reach, and shaking it into the lifting tube 140.

[0027] An airbag 410 is added and located in the forward direction of the scraper 310. During the expansion and contraction of the airbag 410, the oil film can be shaken, thereby increasing the speed at which the oil film enters the lifting tube 140 and the amount of oil film collected. When the airbag 410 is closest to the lifting tube 140, it can drive the oil film near the lifting tube 140 to shake, and shake the part around the lifting tube 140 that the scraper 310 cannot reach, thereby shaking the surface oil film into the lifting tube 140, thereby improving the efficiency of collecting the oil film.

[0028] Embodiment 3: During the use of Embodiment 2, the collection effect of the oil film is improved by the expansion and contraction of the airbag 410. However, the expansion of the airbag 410 will cause the water below the oil film to sway, thereby causing the swaying water to enter the oil outlet pipe 150. Based on this, the solution of Embodiment 2 is improved, such as Fig.14 As shown: There are multiple air bags 410 and air pumps 420, respectively, and they correspond to each other one by one; A plurality of air bags 410 are fixed on one side of the scraper 310 in sequence from top to bottom.

[0029] When the scraper 310 moves in the water and oil film, the airbag 410 flush with the oil film can be controlled to be inflated separately, so that it can be continuously expanded and contracted, which can shake the oil film on the surface, and can increase the speed of its entry into the lifting tube 140 and the amount of oil film collected; and when the scraper 310 is closest to the lifting tube 140, the airbag 410 flush with the oil film is controlled to be inflated separately, and the expansion and contraction of the airbag 410 drives the oil to shake, and the part around the lifting tube 140 that the scraper 310 cannot reach is shaken, and the oil film on the surface is shaken into the lifting tube 140, further improving the efficiency of oil film collection.

[0030] After the airbag 410 is divided into multiple parts, the amount of inflation required to make the airbag 410 expand and contact the oil film to a certain extent also becomes smaller. At the same inflation speed, the frequency of expansion and contraction increases, thereby improving the shaking and collecting effect of the oil film; the airbag 410 located at the oil surface is expanded separately to reduce the shaking degree of water, thereby reducing the amount of water entering the oil outlet pipe 150, thereby improving the collection effect of the oil film; at the same time, multiple airbags 410 are arranged in sequence from top to bottom to adapt to different oil level heights, thereby further improving the collection effect of the oil film.

[0031] Embodiment 4: During the use of embodiment 3, the oil film is intercepted by the scraper 310 and the telescopic plate 320. When the two rise in height to separate from the separation tank 112, a large amount of oil film will remain on the surface of the airbag 410 in front of the scraper 310. In the process of the conveyor belt 170 driving the connecting component 200 gradually away, the oil on the scraper 310 will gradually drip, resulting in a reduction in the collection effect; at the same time, when the scraper 310 is separated from the separation tank 112, the telescopic plate 320 will automatically reset. At this time, the oil attached to the scraper 310 will vibrate to the upper side of the bracket 180 and the storage rack 110, resulting in a reduction in the collection efficiency. Based on this, the solution of embodiment 3 is improved, such as Figure 2 , Figure 15-16 As shown: Also includes an interception rope 500; In the initial state, the length direction of the intercepting rope 500 is perpendicular to the conveying direction of the conveyor belt 170; The two ends of the interception rope 500 are respectively fixed to the sides of the two brackets 180 close to each other; The interception rope 500 is an elastic rope; When the conveyor belt 170 drives the scraper 310 to rise in height, the front of the scraper 310 moves against the interception rope 500; The midpoint of the intercepting rope 500 is directly above the lifting tube 140 .

[0032] When the conveyor belt 170 drives the scraper 310 and the telescopic plate 320 to rise, the scraper 310 will come into contact with the intercepting rope 500. In the process of continuous rising and moving forward, it will come into contact with the intercepting rope 500 and deform. The oil attached to the surface of the airbag 410 in front of the scraper 310 will be scraped off through the intercepting rope 500. In the process of the telescopic plate 320 detaching from the separation tank 112 and resetting, it will come into contact with the deformed intercepting rope 500. The intercepting rope 500 will reduce the resetting speed and reduce the vibration generated. The oil scraped off by the intercepting rope 500 will drip into the separation tank 112 and the lifting tube 140. When the scraper 310 and the telescopic plate 320 do not come into contact with the intercepting rope 500, the oil will gather at the midpoint of the intercepting rope 500 due to the gravity of the oil and drip into the lifting tube 140.

[0033] The intercepting rope 500 can intercept the oil film remaining in front of the scraper 310, collect it, and drip it into the separation tank 112 and the lifting pipe 140. When the scraper 310 and the telescopic plate 320 do not conflict with the intercepting rope 500, the gravity of the oil gathers in the middle section of the intercepting rope 500 and drips into the lifting pipe 140, thereby improving the collection effect. At the same time, the deformed intercepting rope 500 can slow down the ejection speed of the telescopic plates 320, reduce the splashing degree of the oil attached to the scraper 310, and further improve the collection effect of the oil film.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
