[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Example:

[0024] Please see Figures 1-4 The present invention provides a technical solution:

[0025] An oil-water separator includes a filter tank 1, an inner platform 103, a filter basket 4 located inside the filter tank 1 and on top of the platform 103, an oil storage tank 2 at the bottom of the filter tank 1, a filter element 5 located inside the oil storage tank 2 and near one end of the filter tank 1, a water storage tank 3 at the bottom of the oil storage tank 2, an oil filter element 6 located inside the oil storage tank 2 and near one end of the water storage tank 3, an oil outlet pipe 201 located on the side of the oil storage tank 2 and on top of the oil filter element 6, and a water outlet pipe 301 located on the side of the water storage tank 3 and at the bottom of the oil filter element 6. Oil tank 2 and water storage tank 3 can be assembled and disassembled, which is convenient for workers to install and also convenient for disassembly and cleaning after long-term use. The filter cake basket 4 is placed in the platform 103 inside the filter cake tank 1, and then the filter cake is placed in the filter cake basket 4. Water and oil drip down due to gravity and flow into the oil storage tank 2. After being filtered by the filter cake filter element 5, it is ensured that only liquid passes through. Solid filter cake remains above the filter cake filter element 5. The liquid continues to permeate due to gravity and enters above the oil filter element 6. The oil filter element 6 ensures that only water passes through. Oil is discharged from the oil outlet pipe 201. Water permeates through the oil filter element 6 and enters the water storage tank 3, and is then discharged from the water outlet pipe 301, thus completing the water and oil separation.

[0026] Furthermore, a second glass window 102 is provided inside the filter cake tank 1 and at the top of the filter cake basket 4, and a first glass window 101 is provided inside the filter cake tank 1 and at the top of the second glass window 102. A first handle 501 is provided on the side of the filter cake filter element 5 away from the oil storage tank 2, and a second handle 601 is provided on the side of the oil filter element 6 away from the oil storage tank 2. The filter cake filter element 5 can be pulled out through the first handle 501, and the oil filter element 6 can be pulled out through the second handle 601, making it convenient to replace the filter elements and extending the service life of the oil separator. The first glass window 101 and the second glass window 102 cover the odor of the filter cake in the filter cake tank 1 to prevent the odor of the filter cake from causing nausea and vomiting in workers. The first glass window 101 and the second glass window 102 prevent filter cake or liquid from splashing out of the filter cake tank 1 during vibration, reducing the workload of workers.

[0027] The top of the platform 103 and the two opposite ends of the filter basket 4 are provided with two sets of first supports 401, and the top of the platform 103 and the two ends away from the first supports 401 are provided with second supports 402. The bottom and inner wall of the filter basket 4 are provided with multiple sets of equally spaced filter holes 403. The two sets of first supports 401 and multiple sets of second supports 402 make the filter basket 4 stand stably on the top of the platform 103. The filter holes 403 enable the filter basket 4 to perform preliminary filtration of the filter residue, so that the liquid can be separated from the filter residue first, and then the next step of water-oil separation can be carried out.

[0028] Secondly, the filter cake basket 4 is equipped with a baffle 9 inside. Both ends of the baffle 9 are equipped with two sets of connecting posts 901. The ends of the multiple sets of connecting posts 901 away from the baffle 9 are equipped with fixing blocks 902. The multiple sets of fixing blocks 902 are designed to be compatible with the filter holes 403. The fixing blocks 902 are inserted into the appropriate filter holes 403 to fix the baffle 9. The baffle 9 thus blocks the filter cake and liquid during vibration and prevents them from splashing.

[0029] Furthermore, a first heating plate 7 is provided inside the filter cake tank 1 on the side away from the filter cake filter element 5, and a second heating plate 701 is provided inside the oil storage tank 2 on the side away from the filter cake filter element 5. In winter or in low-temperature areas, the oil will solidify and the water will freeze, making it impossible to separate from the filter cake. When the power is turned on, the first heating plate 7 heats the filter cake in the filter cake tank 1, causing the liquid to melt and drip. The second heating plate 701 keeps the oil in the oil storage tank 2 flowing, preventing it from solidifying and clogging, and allowing it to continue flowing until it is discharged from the oil outlet pipe 201.

[0030] Furthermore, a first sealing ring 202 is provided inside the oil storage tank 2 and outside the filter residue tank 1, and a second sealing ring 302 is provided inside the water storage tank 3 and outside the oil storage tank 2. The first sealing ring 202 ensures the sealing between the filter residue tank 1 and the oil storage tank 2, and the second sealing ring 302 ensures the sealing between the oil storage tank 2 and the water storage tank 3, ensuring that there are no gaps that would allow liquid to leak out.

[0031] Furthermore, each of the two sets of second supports 402 has a vibrating column 801 at its bottom and inside the placement platform 103. Each of the two sets of vibrating columns 801 has a vibrating motor housing 8 at its end away from the second support 402. Each of the two sets of vibrating motor housings 8 has a vibrating motor inside. The ends of the two sets of vibrating columns 801 away from the second support 402 are respectively fixedly connected to the vibrating motor drive ends inside the two sets of vibrating motor housings 8. When the power is turned on, the vibrating motor drive ends inside the vibrating motor housings 8 vibrate, thereby driving the vibrating column 801 to vibrate, which in turn drives the second support 402 to vibrate, which in turn drives the filter basket 4 to vibrate, thereby fully shaking out the liquid in the filter residue, reducing the amount of liquid residue in the filter residue, and making it easier to sort waste.

[0032] In this embodiment, the specific implementation scenario is as follows: In actual use, the filter cake tank 1, oil storage tank 2, and water storage tank 3 are assembled together. The first sealing ring 202 ensures the sealing between the filter cake tank 1 and the oil storage tank 2, and the second sealing ring 302 ensures the sealing between the oil storage tank 2 and the water storage tank 3. The first glass window 101 is moved horizontally above the second glass window 102. The filter cake basket 4 is placed on the platform 103 inside the filter cake tank 1, and then the filter cake is placed into the filter cake basket 4. The fixing block 902 is inserted into the appropriate filter hole 403 to fix the baffle 9. The first glass window 101 is moved horizontally back to its original position. The first glass window 101 and the second glass window 102 are closed. The power is turned on, and the vibration motor drive end inside the vibration motor housing 8 vibrates, causing the vibration column 801 to vibrate, thereby causing the second support 402 to vibrate, which in turn causes the filter cake basket 4 to vibrate, thus fully shaking out the filter cake. The liquid in the residue is blocked by baffle 9 during vibration. Water and oil drip down due to gravity and shaking and flow into the oil storage tank 2. After being filtered by the residue filter element 5, only liquid passes through. Solid residue remains above the residue filter element 5. Liquid continues to permeate due to gravity and enters above the oil filter element 6. The oil filter element 6 ensures that only water passes through. Oil is discharged from the oil outlet pipe 201. Water permeates the oil filter element 6 and enters the water storage tank 3, and is then discharged from the water outlet pipe 301, thus completing the water-oil separation. In winter, the first heating plate 7 heats the residue in the residue tank 1, causing the solidified oil and ice to melt and drip down. The second heating plate 701 keeps the oil in the oil storage tank 2 flowing, preventing it from solidifying and clogging, and allowing it to continue flowing until it is discharged from the oil outlet pipe 201, thus completing the water-oil separation. Compared with the existing oil-water separation tank, the present invention improves the overall practicality of the oil-water separation tank through its design.
