Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to a vertical oil-water separation device. Background Technology

[0002] Oil-water separation equipment mainly utilizes the density difference between oil and water to achieve oil-water separation through methods such as gravity separation, centrifugal separation, and air flotation. For example, the Alfa Laval PureBilge oil-water separator uses centrifugal separation, employing the centrifugal force generated by high-speed rotation to separate oil and emulsion from oil-containing water.

[0003] Existing equipment typically works by pouring oil and water into a filter screen to filter out impurities before discharging them through an oil drain and a water drain. However, a drawback is that the oil will solidify after cooling, making it difficult to remove the grease. Utility Model Content

[0043] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0044] Reference Figure 1-6 This utility model provides a vertical oil-water separation device, including a vertical cabinet 1, inside which is a separation tank 2. A wastewater inlet 12 is located in the middle of one side of the vertical cabinet 1, and an oil outlet 14 is located on the other side. The top of the separation tank 2 has a water outlet 21 and an oil outlet 22. The oil outlet 22 is connected to the oil outlet 14, and one side of the water outlet 21 is connected to a water outlet 11. A water pump 3 is installed in the separation tank 2 and connected to the wastewater inlet 12 to pump wastewater into the separation tank 2. A cleaning and drain outlet 13 is connected to one side of the bottom of tank 2. The bottom of the oil outlet 22 is provided with multiple oil passage holes 23. A heating plate 24 is installed at the bottom of the oil outlet 22 and is embedded in the bottom of the oil outlet 22. The heating plate 24 is connected to a heating device 25, which is installed on the outer wall of the separation tank 2. The bottom of the water outlet 21 is provided with a connecting pipe 26, which is inserted into the lower part of the separation tank 2. The separation tank 2 is provided with a frequency converter 29, which is electrically connected to the water pump 3 and the heating device 25.

[0045] Specifically, by connecting the various pipes to the oil outlet 14, water outlet 11, and sewage inlet 12 respectively, the sewage is pumped into the separation tank 2 by the water pump 3. After sedimentation, due to the different densities of oil and water, the oil will float to the top and then enter the oil outlet 22 through the oil passage hole 23, and then be discharged through the pipe in the oil outlet 14. The water is pumped from the bottom to the water outlet 21 through the internal connecting pipe 26 and then discharged through the water outlet 11. When discharging oil, the oil may clump due to temperature. In this case, the heating device 25 is activated to heat the heating plate 24 so that the oil at the top comes into contact with the heating plate 24 and melts. The oil then flows from the oil passage hole 23 into the oil outlet 22 and is discharged from the oil outlet 14 in the oil outlet 22. This way, there is no fear of the oil clumping and blocking the hole, preventing it from flowing out.

[0046] Then, the heating plate 24 is set into a square shape that matches the bottom of the oil outlet 22. Then, horizontal plates are arranged horizontally in the middle, forming a groove 27 between the horizontal plates. The filter assembly 4 is set in the groove 27. The filter assembly 3 is fitted with a filter frame 41 with threaded holes 28 on both sides of the groove 27 at the bottom of the oil outlet 22. The filter frame 41 is then installed on the groove 27 with screws. Then, the oil passage hole 23 set in the groove 27 is covered with a filter screen 42 to filter the oil and prevent small particles of impurities from mixing with the oil. This arrangement also has the advantage of heating around the oil passage hole 23, allowing the oil to pass through the oil passage hole 23 quickly without clogging. The bottom of the oil outlet 22 can be made of metal for better heat conduction. The horizontal plates extend to the bottom of the oil outlet 22 to increase melting efficiency.

[0047] After use, the top cover 6 can be opened, and the flip cover 62 can be flipped up by holding the handle 63. Then, the screws can be removed to take out the filter assembly for cleaning and continued use, or it can be replaced later. If the water pump needs to be repaired, the switch door 15 can be opened for repair. Finally, the dirt at the bottom of the sewage can be discharged by cleaning the drain outlet.

[0048] During operation, the power indicator 16 illuminates when the power is plugged in. Then, press the start switch 18 to start the machine for separation. The timer 17 can also be used for timed operation. Additionally, the side wall of the vertical cabinet 1 has multiple louvers 5 for heat dissipation of the water pump 3.

[0049] Working principle:

[0050] Press the start switch 18, and the water pump 3 will draw the oily wastewater into the separator tank 2 through the wastewater inlet 12. The oil will float on top. As the water level rises, the oil will pass through the oil passage hole 23 into the oil outlet tank 21 and then be discharged through the oil outlet 14. The water at the bottom will then enter the water outlet tank 22 through the connecting pipe 26 and be discharged through the water outlet 11. This allows for the simultaneous pumping and separation of oily wastewater. At the same time, the heating plate can be activated to heat the oil and melt the clumps, preventing them from clogging the oil passage hole 23. Finally, after filtration, the dirt at the bottom will be discharged through the cleaning drain 13.
