Description

Technical Field

[0001] This utility model belongs to the technical field of oil-water separation equipment, and in particular relates to a novel automatic oil-water separation device. Background Technology

[0002] An automatic oil-water separator is an advanced device capable of automatically separating oil and water from an oil-water mixture. It plays a crucial role in numerous industries such as catering, petrochemicals, machinery manufacturing, and shipbuilding, primarily for treating oily wastewater generated by these industries. Its core purpose is to efficiently recover oil resources, achieving resource reuse on the one hand, and ensuring that the treated water meets environmental discharge standards on the other, greatly reducing environmental pollution. Based on different separation principles, automatic oil-water separators are mainly divided into several types, including gravity-type, centrifugal-type, coalescence-type, and flotation-type, to meet the oil-water separation needs in different scenarios.

[0003] Existing gravity-based oil-water separators primarily utilize the density difference between oil and water, causing the oil to naturally float to the surface, thus achieving separation. However, this separation method has some significant drawbacks. First, the oil sludge tends to clump together after floating to the surface, making it difficult for the drain pipe to discharge it smoothly, thus hindering thorough oil-water separation. Second, oil sludge easily adheres to the inner wall of the separation container, accumulating over time. This not only reduces the effective volume of the separation container but also adversely affects subsequent separation processes. Utility Model Content

[0004] The purpose of this invention is to provide a novel automatic oil-water separation device. By driving a curved scraper through a transmission chain, the scraper not only pushes the oil sludge floating on the water surface into the auxiliary sewage discharge chamber, but also scrapes off the oil sludge adhering to the inner wall of the separation chamber. This solves the problems of incomplete oil-water separation in existing gravity-type oil-water separation devices when processing oil-water mixtures, and the fact that oil sludge easily adheres to the inner wall of the separation container during separation, thus affecting the separation effect of the device.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] This utility model is a novel automatic oil-water separation device, comprising a slag removal box and a separation box. The separation box includes a separation chamber and an auxiliary sewage discharge chamber. The separation chamber has two symmetrical sprockets that rotate and cooperate with each other on its two inner sides. A transmission chain is sleeved on the circumferential sides of the two sprockets. A connecting piece is fixedly installed on the transmission chain. A curved scraper is fixedly installed at one end of the two connecting pieces. An auxiliary scraper is fixedly installed on the inner wall of the auxiliary sewage discharge chamber.

[0007] The present invention is further configured such that the connecting member includes a base plate fixedly connected to the transmission chain, two symmetrical first connecting discs are fixedly connected to one end of the base plate, a connecting rod is fixedly connected between the two first connecting discs, two symmetrical second connecting discs are rotatably fitted to the circumferential side of the connecting rod, and a connecting plate is fixedly connected to the circumferential side of the two second connecting discs.

[0008] The present invention is further configured such that a torsion spring is sleeved on the periphery of the connecting rod between the two second connecting discs, and the two ends of the torsion spring are respectively inserted into the base plate and the connecting plate.

[0009] The present invention is further configured such that a heater is fixedly installed on one side wall of the separation chamber, an observation window is fixedly installed on the other side wall of the separation chamber, a first oil drain pipe is fixedly connected to the bottom of the auxiliary sewage discharge chamber, a second oil drain pipe is fixedly connected to one side wall of the separation chamber, and an oil collection tank is fixedly connected to one end of the first oil drain pipe and the second oil drain pipe.

[0010] The present invention is further configured such that a drain pipe is fixedly connected to the other side wall of the separation chamber, and an empty pipe is fixedly connected to the bottom of the separation chamber.

[0011] The present invention is further configured such that a water inlet pipe is fixedly connected to one side of the slag removal box, a first screen is fixedly installed inside the slag removal box, and a second screen is fixedly installed inside the slag removal box on one side of the first screen, wherein the diameter of the screen hole of the first screen is larger than that of the second screen.

[0012] The present invention is further configured such that a transfer pipe is fixedly connected to the other side of the slag removal box, the transfer pipe is connected to the separation chamber, and two rows of slag pipes are fixedly connected to the bottom of the slag removal box, with a slag collection bucket fixedly connected to one end of each of the two slag discharge pipes.

[0013] This utility model has the following beneficial effects:

[0014] This invention uses two sets of transmission chains to drive two connecting parts to move, so that the two connecting parts together drive the curved scraper to slide on the water surface, thereby concentrating the oil sludge in front of the curved scraper. As the curved scraper continues to move obliquely upward, its edge will first contact the inner inclined surface of the separation chamber. Then, the curved scraper will advance smoothly forward on the inner inclined surface, and its front end will continuously push the oil sludge on the inner inclined surface, causing the oil sludge to accumulate. Subsequently, the surface of the curved scraper with accumulated oil sludge will contact the edge of the auxiliary scraper, and the edge of the auxiliary scraper will slide against the surface of the curved scraper, thereby scraping off the oil sludge on the curved scraper. This prevents the oil sludge from clogging the oil drain pipe, and at the same time scrapes off the oil sludge attached to the inner wall of the separation chamber, so as not to affect the subsequent separation effect.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Specific Implementation

[0026] Please see Figure 1-5This utility model is a novel automatic oil-water separation device, comprising a slag removal box 1 and a separation box 2. The separation box 2 includes a separation chamber 3 and an auxiliary discharge chamber 4. Two symmetrical sprockets 5 are rotatably fitted on opposite inner sides of the separation chamber 3. A transmission chain 6 is sleeved on the circumference of the two sprockets 5. Connecting parts 7 are fixedly installed on the transmission chain 6. A curved scraper 8 is fixedly installed at one end of each of the two connecting parts 7. An auxiliary scraper 9 is fixedly installed on the inner wall of the auxiliary discharge chamber 4. During the oil-water separation process in the separation chamber 3, the oil sludge floats to the water surface and clumps together. An external power source can drive the sprockets 5 to rotate, thereby pushing the transmission chain 6 to move. The transmission chain 6 is driven by two sprockets 5 to rotate. Connector 7 drives the curved scraper 8 to slide on the water surface, concentrating the oil sludge in front of the curved scraper 8. As the curved scraper 8 continues to move diagonally upward, its edge will first contact the inner inclined surface of the separation chamber 3. Then, the curved scraper 8 will smoothly advance forward on the inner inclined surface, and its front end will continuously push the oil sludge, causing the oil sludge to accumulate. Subsequently, the surface of the curved scraper 8 with accumulated oil sludge will contact the edge of the auxiliary scraper 9, and the edge of the auxiliary scraper 9 will slide against the surface of the curved scraper 8, thereby scraping off the oil sludge on the curved scraper 8. Finally, under the action of gravity, the oil sludge will fall to the bottom of the auxiliary sewage chamber 4. The whole process is controlled by a timer in the electrical control box to achieve 24-hour automatic start and stop.

[0027] Specifically, the connecting component 7 includes a base plate 10 fixedly connected to the transmission chain 6. Two symmetrical first connecting discs 11 are fixedly connected to one end of the base plate 10. A connecting rod 12 is fixedly connected between the two first connecting discs 11. Two symmetrical second connecting discs 13 are rotatably fitted around the connecting rod 12. A connecting plate 14 is fixedly connected to the circumference of the two second connecting discs 13. A torsion spring 15 is sleeved between the two second connecting discs 13 on the circumference of the connecting rod 12. The two ends of the torsion spring 15 are respectively inserted into the base plate 10 and the connecting plate 14. During the process of the curved scraper 8 scraping off the oil stains on the inclined surface in the separation chamber 3, since the curved scraper 8 needs to have a certain elastic rotation capability, in addition to the scraper needing to be made of special stainless steel to have a certain elasticity and hardness, the connecting plate 14 is also provided so that it can rotate relative to the base plate 10. At the same time, the torsion spring 15 drives the connecting plate 14 to return to its original position, thereby meeting this requirement.

[0028] A heater 19 is fixedly installed on one side wall of the separation chamber 3. The oil-water mixture in the separation chamber 3 is heated by the heater 19 to prevent the oil from becoming viscous or even solidifying in a low-temperature environment, thus affecting its ability to float to the water surface.

[0029] An observation window 20 is fixedly installed on the other side wall of the separation chamber 3. The bottom of the auxiliary sewage chamber 4 is fixedly connected to the first oil drain pipe 16. The side wall of the separation chamber 3 is fixedly connected to the second oil drain pipe 17. One end of the first oil drain pipe 16 and the second oil drain pipe 17 are fixedly connected to the oil collection tank 18. The other side wall of the separation chamber 3 is fixedly connected to the drain pipe 21. The bottom of the separation chamber 3 is fixedly connected to the drain pipe 22. The accumulation of floating oil can be observed through the observation window 20. When the grease accumulates to a certain height, the valve on the second oil drain pipe 17 is opened, so that the grease floating in the separation chamber 3 is discharged into the oil collection tank 18 through the second oil drain pipe 17. And by opening the valve on the first oil drain pipe 16, the grease block that falls to the bottom of the auxiliary sewage chamber 4 can be discharged into the oil collection tank 18 through the first oil drain pipe 16. After removing the grease from the oil-water mixture, the water in the separation chamber 3 can be discharged through the drain pipe 21. The drain pipe 22 at the bottom of the separation chamber 3 is used to discharge the residue accumulated at the bottom of the separation chamber 3.

[0030] A water inlet pipe 23 is fixedly connected to one side of the slag removal box 1. A first screen 24 is fixedly installed inside the slag removal box 1. A second screen 25 is fixedly installed inside the slag removal box 1 on one side of the first screen 24. The diameter of the screen holes of the first screen 24 is larger than that of the second screen 25. The diameter of the screen holes of the first screen 24 is no greater than 8 mm, and the diameter of the screen holes of the second screen 25 is no greater than 3 mm. mm, allowing the two to separate impurities of different sizes. A transfer pipe 28 is fixedly connected to the other side of the slag removal box 1, and the transfer pipe 28 is connected to the separation chamber 3. Two rows of slag pipes 26 are fixedly connected to the bottom of the slag removal box 1, and one end of the two rows of slag pipes 26 is fixedly connected to the slag collection bucket 27. Before oil-water separation, solid impurities in the oil-water mixture should be removed first. Therefore, the oil-water mixture containing impurities is first discharged into the slag removal box 1 through the water inlet pipe 23. After the first screen 24 and the second screen 25 separate the impurities of different sizes, the oil-water mixture after removing impurities is discharged into the separation chamber 3 through the transfer pipe 28 for oil-water separation. At the same time, the impurities screened by the first screen 24 and the second screen 25 are discharged into the slag collection bucket 27 through the two rows of slag pipes 26.

[0031] The operation process of this embodiment is as follows: First, the oil-water mixture is discharged into the slag removal box 1 through the water inlet pipe 23. After impurities are separated by the first screen 24 and the second screen 25, the oil-water mixture after impurity removal is discharged into the separation chamber 3 through the transfer pipe 28. Gravity causes the grease to float on the water surface, and the accumulation of floating oil can be observed through the observation window 20. When the grease accumulates to a certain height, the valve on the second oil drain pipe 17 is opened, so that the grease floating in the separation chamber 3 is discharged into the oil collection tank 18 through the second oil drain pipe 17. When the oil sludge on the water surface is observed to have accumulated into clumps, in order to prevent it from clogging the second oil drain pipe 17, an external power source can be used to drive the sprocket 5 to rotate, thereby driving the transmission. As chain 6 moves, the transmission chain 6 drives the curved scraper 8 to slide on the water surface via two connecting parts 7, concentrating the oil sludge in front of the curved scraper 8. As the curved scraper 8 continues to move obliquely upward, its edge first contacts the inner inclined surface of the separation chamber 3. Then, the curved scraper 8 smoothly advances forward on the inner inclined surface, and its front end continuously pushes the oil sludge, causing it to accumulate. Subsequently, the surface of the curved scraper 8 with accumulated oil sludge contacts the edge of the auxiliary scraper 9, and the edge of the auxiliary scraper 9 slides against the surface of the curved scraper 8, thereby scraping off the oil sludge on the curved scraper 8. Finally, under the action of gravity, the oil sludge falls to the bottom of the auxiliary discharge chamber 4 and is discharged into the oil collection tank 18 through the first oil discharge pipe 16.
