An automatic oil-water automatic separation device

Abstract

An automatic oil-water separator includes a base plate with a rectangular frame welded upwards along its outer periphery. One end of the rectangular frame has a water outlet. A partition is welded inside the rectangular frame, with a notch formed at its lower end. The upper end of the other end of the rectangular frame has a scraping port, the lower end of which is higher than the water outlet. The scraping port facilitates the discharge of acid-resistant oil, while the water outlet facilitates water discharge. The different heights of the two ports facilitate the scraping of the acid-resistant oil through the scraping port. Specifically, when wastewater containing acid-resistant oil is poured into the separator, the oil floats at the scraping port, while water flows from the notch at the lower end of the partition towards the water outlet. When the wastewater reaches the height of the water outlet, it gradually overflows, while the acid-resistant oil accumulates at the scraping port, where it can be scraped off.

Description

Technical Field

[0001] This utility model relates to the field of lead-acid batteries, and in particular to an automatic oil-water separation device. Background Technology

[0002] Lead-acid battery electrolyte is highly corrosive, so lead-acid batteries must be coated with anti-acid oil before charging. During battery cleaning, this protective oil needs to be thoroughly rinsed off. Therefore, the water used for battery cleaning contains a large amount of anti-acid oil. This oil is difficult to treat in wastewater. It is usually treated by adding alkali for saponification, but this method can easily lead to foul odors in the wastewater over time. Direct discharge of this water not only pollutes water bodies but also causes air pollution. Utility Model Content

[0003] This invention provides an automatic oil-water separation device to address the shortcomings of the prior art and solve the problem of inconvenient separation of acid-resistant oil during formation charging and battery cleaning.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] An automatic oil-water separator includes a base plate with a rectangular frame welded upwards along its outer periphery. One end of the rectangular frame has a water outlet. A partition is welded inside the rectangular frame, with a notch formed at its lower end. The upper end of the other end of the rectangular frame has a scraping port, the lower end of which is higher than the water outlet. The scraping port facilitates the discharge of acid-resistant oil, while the water outlet facilitates the discharge of water. The different heights of the two ports facilitate the scraping of the acid-resistant oil through the scraping port. Specifically, when wastewater containing acid-resistant oil is poured into the separator, the oil floats at the scraping port, while water flows from the notch at the lower end of the partition towards the water outlet. When the wastewater reaches the height of the water outlet, it gradually overflows, while the acid-resistant oil accumulates at the scraping port, where it can be scraped off.

[0006] Furthermore, in order to facilitate the collection of the scraped anti-acid oil and avoid the problem of it falling directly and causing inconvenience, a scraping tongue is bent outward from the lower end of the scraping opening. An inclined plate extends downward from the outer end of the scraping tongue, and an end baffle is bent vertically from the outer end of the inclined plate. Side plates are provided on both sides of the scraping tongue, the inclined plate, and the end baffle. The inner end of the side plates is formed on a rectangular frame. The setting of the inclined plate improves the storage capacity of the anti-acid oil and facilitates the scraping operation of the anti-acid oil.

[0007] Furthermore, a scraper is movably installed inside the upper end of the rectangular frame, and a movable horizontal plate is welded to the upper end of the scraper. The two ends of the movable horizontal plate are placed at the upper end of the rectangular frame, and the scraper moves between the partition and the scraping port. The scraper facilitates the scraping operation of the acid-resistant oil.

[0008] Furthermore, guide strips are welded to the upper ends of both sides of the rectangular frame, and the two ends of the movable horizontal plate are bent downward to form concave parts. The guide strips are locked in the concave parts to guide the movement of the scraper, thereby improving the scraping effect.

[0009] Furthermore, to facilitate gripping during scraping operations, an outwardly extending convex plate is bent outward at the lower end of the concave part.

[0010] Furthermore, in order to facilitate the control of wastewater flow, L-shaped parts are formed on both sides of the lower end of the partition, and movable baffles are inserted inside the L-shaped parts. The upper end of the movable baffles is bent with a protrusion, and an upper extension rod is welded on the protrusion.

[0011] Furthermore, in order to control the insertion depth of the movable baffle, an upper baffle is formed at the upper end of the movable baffle.

[0012] The advantages of the above technical solution are:

[0013] This invention facilitates the separation of anti-acid oil and wastewater in cleaning solutions, reducing the cost of such cleaning water treatment and improving the separation effect of anti-acid oil and wastewater. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings.

[0015] Fig. 1 A three-dimensional structural diagram of one embodiment is shown.

[0016] Fig. 2 A three-dimensional structural diagram of the partition is shown. Detailed Implementation

[0017] like Figs. 1-2 As shown, an automatic oil-water separator includes a base plate 1. A rectangular frame 10 is welded upwards along the outer periphery of the base plate 1. One end of the rectangular frame 10 has a water outlet 11. A partition 21 is welded inside the rectangular frame 10, and a notch 24 is formed at the lower end of the partition 21. A scraping port 120 is formed at the upper end of the other end of the rectangular frame 10, and the lower end of the scraping port 120 is higher than the height of the water outlet 11.

[0018] In this embodiment, when separating wastewater and acid-resistant oil from the cleaning water, the operator injects cleaning water from the end with the scraper port 120. After the cleaning water is injected, the wastewater fills the entire rectangular frame 10 through the notch 24. When the wastewater reaches the outlet port 11, it is discharged from the outlet port 11. The acid-resistant oil is located at the upper part of the space between the scraper port 120 and the partition plate 21. As the cleaning water is injected, this acid-resistant oil will further accumulate and be scraped out from the scraper port 120 during the injection process. This achieves the separation of acid-resistant oil and wastewater.

[0019] In some embodiments, the scraping port 120 of an automatic oil-water separator has a scraping tongue 12 that extends outward from the lower end, and a sloping plate 13 that extends downward from the outer end of the scraping tongue 12. An end baffle 14 is vertically bent from the outer end of the sloping plate 13. Side plates 15 are provided on both sides of the scraping tongue 12, the sloping plate 13 and the end baffle 14. The inner end of the side plate 15 is formed on the rectangular frame 10.

[0020] In this embodiment, when the anti-acid oil is scraped off, it will gather along the scraping tongue 12 into the space formed by the inclined plate 13 and the end baffle 14, so that it can be stored later.

[0021] In some embodiments, a scraper 17 is movably provided inside the upper end of a rectangular frame 10 of an automatic oil-water separator. A movable horizontal plate 18 is welded to the upper end of the scraper 17, and both ends of the movable horizontal plate 18 are placed at the upper end of the rectangular frame 10. The scraper 17 moves between the partition plate 21 and the scraping port 120. Guide strips 16 are welded to the upper ends of both sides of the rectangular frame 10. The two ends of the movable horizontal plate 18 are bent downward to form concave parts 19. The guide strips 16 are engaged in the concave parts 19, and the lower end of the concave parts 19 is bent outward to form an outward protruding plate 20.

[0022] In this embodiment, when performing the scraping operation, the acid-resistant oil floating on the wastewater can be quickly scraped off from the scraping port 120 by moving the scraper 17.

[0023] In some embodiments, an automatic oil-water separator has L-shaped parts 25 formed on both sides of the lower end of the partition 21. A movable baffle 26 is inserted into the L-shaped part 25. A protrusion 28 is bent at the upper end of the movable baffle 26. An upper extension rod 29 is welded on the protrusion 28. An upper baffle 27 is formed at the upper end of the movable baffle 26.

[0024] In this embodiment, if sufficient time is required for the natural stratification of the anti-acid oil and wastewater, the moving baffle 26 can be moved to facilitate the flow of wastewater, thereby providing sufficient time for the separation between the anti-acid oil and wastewater. During operation, the height of the moving baffle 26 can be adjusted by the upper extension rod 29. Of course, in order to ensure the certainty of the position of the moving baffle 26 after adjustment, anti-slip rubber pads can be provided on the outer wall of the moving baffle 26 and the inner wall of the L-shaped part 25.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
