Description

Technical Field

[0001] The invention relates to the technical field of feed oil, in particular to a feed oil waste liquid collecting tank. Background Art

[0002] In recent years, the feed oil industry has flourished, with production continuing to expand. During the feed oil production process, a large amount of waste liquid is generated. This waste liquid has a complex composition, containing not only valuable oils and fats but also feed residues and other impurities. With growing environmental awareness and increasingly stringent environmental regulations, proper treatment of feed oil waste liquid has become an inevitable requirement for the industry's sustainable development.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This type of feed oil waste liquid collection tank is equipped with a separation mechanism. When the feed oil waste liquid is injected, the grease and solid substances such as feed residues in the waste liquid are quickly and effectively separated, which greatly facilitates the subsequent work of treating different components separately. The collection tank adopts an inclined chute body, and the waste liquid can flow naturally under the action of gravity. During the flow process, grease and solid residues with different densities are gradually separated into layers, effectively realizing solid-liquid separation and improving overall processing efficiency.

[0017] 2. This type of feed oil waste liquid collection tank is equipped with a second separation mechanism to guide the waste liquid in for static treatment, so that the oil is naturally stratified due to density differences, and the semiconductor refrigeration and heating module plays an auxiliary role. When it is necessary to promote the coagulation of oil, the module quickly cools down and lowers the ambient temperature, so that the oil solidifies faster and forms an easily separable solid state inside the collection tank, so that the oil will not be mixed into the wastewater, ensuring that the wastewater can be discharged smoothly, greatly improving the overall efficiency and quality of waste liquid treatment.

[0018] 3. This type of feed oil waste liquid collection tank, by setting up the second separation mechanism, can not only realize the oil-liquid separation efficiently, but also can adjust to the changes in the external environmental temperature. In a cold environment, it automatically starts the semiconductor refrigeration and heating module to heat up to prevent the oil from being too viscous and difficult to separate due to the low temperature; when it is hot, it will cool moderately to accelerate the stratification of the oil. When it is necessary to clean the residual oil in the collection tank, the module can heat up, and the stubbornly adhered oil will be softened and easily separated from the surface of the tank, which greatly improves the oil separation efficiency and cleaning convenience.

[0019] 4. This type of feed oil waste liquid collection tank is equipped with auxiliary mechanisms. Since a large amount of grease is easily attached to the side of the inclined chute during the waste liquid treatment process, an adaptive cleaning method is adopted to closely adhere to the chute surface to ensure that the grease inside the collection tank is fully removed, avoiding grease accumulation that affects the subsequent waste liquid treatment process, and comprehensively ensuring the thoroughness and efficiency of the collection tank cleaning work.

[0040] The inner wall of the inner notch 301 is flush with the inner wall of the waste liquid collection tank 2, the outer surface of the card frame 303 is in contact with the inner wall of the waste liquid collection tank 2, the outer surface of the torsion spring 305 is fixedly connected to the outer surface of the waste liquid collection tank 2, the first filter plate 304 is used to filter and separate the waste liquid, the outer surface of the bellows 306 is fixedly connected to the outer surface of the rotating rod 302, the outer surface of the arc baffle 307 is in contact with the outer surface of the card frame 303, and the outer surface of the limit shaft column 308 is in contact with the outer surface of the waste liquid collection tank 2 The torsion spring 305 is used to elastically limit the first filter plate 304. A rubber layer is provided on the outer surface of the end face where the arc baffle 307 contacts the card frame 303, and the rubber layer will not be corroded by the waste liquid, thereby elastically protecting and limiting the card frame 303 and the first filter plate 304. When the torsion spring 305 does not limit the card frame 303, the card frame 303 is in a horizontal position, the inner notch 301 is provided with a vertical section and an inclined groove section, and the torsion spring 305 is protected by a bellows 306.

[0041] The separation mechanism 2 4 includes a first screw 401, which is rotatably connected to the waste liquid collection tank 2. The outer surface of the first screw 401 is rotatably connected to a slider frame 402, and the outer surface of the slider frame 402 is fixedly connected to a bellows 2 403. The outer surface of the slider frame 402 is provided with a slope 404, and the interior of the slider frame 402 is fixedly connected to a semiconductor refrigeration and heating module 1 405. The bellows 2 403 is used to protect the first screw 401.

[0042] The separation mechanism 2 4 also includes a semiconductor refrigeration and heating module 2 406, which is fixedly connected to the outer surface of the waste liquid collection tank 2. The internal thread of the inner groove 301 is connected to a threaded filter plate 407. The outer surface of the waste liquid collection tank 2 is fixedly connected to an electric valve 408, and the slider frame 402 is used to clean the inner groove 301.

[0043] The outer surface of the inclined surface 404 contacts the inner wall of the inner notch 301, the upper surface of the threaded filter plate 407 is flush with the inner wall of the inner notch 301, the threaded filter plate 407 is threadedly connected to the waste liquid collection tank 2, the semiconductor cooling and heating module 1 405 and the semiconductor cooling and heating module 2 406 are used to control the temperature of the inner notch 301. When not in operation, the electric valve 408 is opened, and the threaded filter plate 407 can be rotated in the opposite direction through the lower end of the electric valve 408 to replace the threaded filter plate 407, and the first The screw 401 drives the movement of the slider frame 402 for protection. When the feed oil is cleaned, the semiconductor refrigeration and heating module 1 405 and the semiconductor refrigeration and heating module 2 406 heat the inner groove 301, which can heat the waste liquid collection tank 2, heat the splashed feed oil, make it slide into the inner groove 301, and clean it. When the waste liquid is separated and filtered multiple times, the semiconductor refrigeration and heating module 1 405 and the semiconductor refrigeration and heating module 2 406 continue to cool it, so that the feed oil and the surface of the inner groove 301 continue to condense.

[0044] The working principle of this embodiment is as follows: when using this feed oil waste liquid collection tank, the first filter plate 304 located on one side of the arc baffle 307 is made to push the card frame 303 to rotate around the rotating rod 302, and the torsion spring 305 is twisted. At this time, the arc baffle 307 is clamped with the waste liquid collection tank 2, and the arc baffle 307 is fixed by threading through the limiting rotating shaft column 308, thereby limiting the position of the first filter plate 304, and when the arc baffle 307 is clamped, the side with the rubber layer contacts the outer surface of the card frame 303, At this time, waste liquid is introduced into the waste liquid collection tank 2, and the solid and liquid of the waste liquid are separated by the first filter plate 304, and the solid is allowed to slide out of the waste liquid collection tank 2 through the inclined first filter plate 304, and the first filter plate 304 is elastically supported by the torsion spring 305, so that when the first filter plate 304 is impacted by the solid in the waste liquid, when the left side of the rotating rod 302 is impacted, the torsion spring 305 twists it, and when the right side of the rotating rod 302 is impacted, the rubber layer of the arc baffle 307 absorbs it, thereby providing protection for the first filter plate 304. After passing through the first filter plate 304, when the injected waste liquid is flush with the inclined groove section of the inner notch 301, the injection of the waste liquid is stopped and the waste liquid is allowed to stand, so that the feed oil inside it is suspended on the surface of the waste liquid. At this time, it is filtered through the threaded filter plate 407, and the outflow speed of the waste water is controlled by the electric valve 408, so that the feed oil gradually contacts the surface of the inner notch 301. At the same time, the semiconductor cooling and heating module 1 405 and the semiconductor cooling and heating module 2 406 cool the feed oil and condense it with the surface of the inner notch 301, so that it will not be discharged with the waste water and is discharged in a cold environment. Under the condition of low temperature, the temperature is increased so that the feed oil can be suspended on the surface of the waste liquid, and when the waste liquid is discharged, the temperature increase gradually fails, causing the feed oil to condense with the surface of the inner groove 301. When the feed oil on the surface of the inner groove 301 needs to be cleaned, the semiconductor refrigeration and heating module 1 405 and the semiconductor refrigeration and heating module 2 406 heat the surface of the inner groove 301 to make the condensation of the feed oil and the inner groove 301 invalid, and the slider frame 402 is driven to move by the first screw 401, and the surface of the inner groove 301 is scraped by the inclined surface 404 to achieve the cleaning of the feed oil.

[0045] Example 2: Please refer to Figure 7-Figure 8On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary mechanism 5 includes an annular column 501, the annular column 501 is slidably connected to the first screw 401, the inside of the annular column 501 is rotatably connected to the second screw 502, the inner wall of the waste liquid collection tank 2 is fixedly connected to the bellows three 503, the outer surface of the second screw 502 is threadedly connected to the rotating plate one 504, the outer surface of the rotating plate one 504 is provided with a scraper one 505, the outer surface of the rotating plate one 504 is rotatably connected to the rotating plate two 507, the outer surface of the rotating plate two 507 is provided with a scraper two 506, the outer surface of the rotating plate two 507 is fixedly connected to the metal spring 508, the scraper one 505 and the scraper two 506 are used to clean the inner wall of the inner notch 301.

[0046] Bellows three 503 is fixedly connected to the outer surface of the annular column 501, and the outer surface of the metal spring 508 is fixedly connected to the outer surface of the rotating plate 1 504. The length of the rotating plate 1 504 is the same as the short side of the inner slot 301. The metal spring 508 is used to elastically support the rotating plate 1 504 and the rotating plate 2 507. The annular column 501 on the outer surface of the first screw 401 limits the second screw 502 and enables the second screw 502 to rotate in the vertical direction. At the same time, bellows three 503 protects the movement of the rotating plate 1 504 and the second screw 502.

[0047] The working principle of this embodiment is as follows: when using this feed oil waste liquid collection tank, the feed oil is cleaned, and at this time the second screw 502 rotates, the rotating plate 1 504 cooperates with the rotating plate 2 507, and the scraper 1 505 and the scraper 2 506 clean the surface of the inner notch 301, and the feed oil is heated by the semiconductor refrigeration and heating module 1 405 and the semiconductor refrigeration and heating module 2 406, and when the rotating plate 1 504 continues to move downward, the chute surface of the chute section causes the rotating plate 2 507 to rotate around the two ends of the rotating plate 1 504, so that the rotating plate 2 507 drives the scraper 2 506 to rotate, so that the scraper 1 505 can completely clean the chute section of the inner notch 301, and the outer surface of the rotating plate 2 507 is in close contact with the outer surface of the chute section of the inner notch 301 through the metal spring 508, and the rotating plate 2 507 can rotate on the surface of the rotating plate 1 504 to restore the horizontal position.
