[0022] Please see Figure 1-4This utility model provides a technical solution: an environmentally friendly raw oil buffer tank with a layered screening structure, comprising a cylindrical tank body 1. The tank body 1 is cylindrical in shape, with an arc-shaped cover 2 at the top of the tank body 1. An air inlet 3 is located on one side of the top of the cover 2, and an exhaust outlet 4 is located on the other side. Several annular discs 5 are equidistantly arranged on the middle outer wall of the tank body 1, with drainage pipes 6 symmetrically arranged on both sides of the annular discs 5. An oil inlet port 7 is located at the bottom of the tank body 1, with a detachable flange 8 on the outside of the oil inlet port 7. A disc-shaped sealing plate 9 is also located at the bottom of the tank body 1, with the bottom of the sealing plate 9 being circular. Three support blocks 10 are equidistantly arranged on the periphery. Several connecting rods 11 are equidistantly arranged at the bottom of the sealing plate 9. The bottom ends of the connecting rods 11 are connected to the filter column plate 12. A channel pipe 13 is connected to the bottom center of the sealing plate 9. The channel pipe 13 is connected to the filter column plate 12. An oil drain pipe 14 is provided at the bottom center of the filter column plate 12. Several buckle plates 15 are equidistantly and symmetrically arranged on the inner wall of the tank body 1. An opening is provided at the top of the buckle plate 15 near the inner wall. The buckle plates 15 at the same height are spaced apart. A bend pipe 16 is also provided at the bottom of the buckle plate 15. The bend pipe 16 is connected to the drain pipe 6.
[0023] A filter screen plate 17 is provided on the inner side of the buckle plate 15. By using the filter screen plate 17 on the inner side of the buckle plate 15, the screened oil is filtered to remove impurities.
[0024] The filter column plate 12 is detachable, and a filter screen plate 18 is installed inside the filter column plate 12. The filter column plate 12 is used to screen and filter oil with more sediment and higher impurity content. The filter column plate 12 can be completely removed for timely maintenance and repair.
[0025] A casting block 19 is symmetrically arranged on both sides of the bottom of the tank 1. The top of the casting block 19 is solid and the bottom is open. There are also two through holes on the top of the casting block 19. Other fixing blocks are inserted through the opening at the bottom of the casting block 19 and connected to the two through holes, which makes it easy to move the tank 1.
[0026] An instrument 20 is installed on the top of the outer wall of the tank 1 near the cover 2. The internal temperature and pressure can be detected by the instrument 20. The instrument 20 can be a multi-functional instrument.
[0027] Working principle: The gas is connected to the air inlet 3 to a compressed gas device to adjust the air pressure inside the tank 1. The exhaust port 4 can also be connected to a waste gas collection device to collect the waste gas. The oil inlet 7 is connected to a crude oil refining device. The crude oil is heated and enters the tank 1. The oil gradually rises and the temperature at the bottom gradually increases. Impurities in the oil gradually settle at the bottom. The oil that floats to the top can be discharged to make different raw materials oil according to the temperature difference. The oil at the bottom can enter the filter column plate 12 through the channel pipe 13. The filter screen plate 18 inside the filter column plate 12 is used to filter out impurities. At the same time, the oil that floats to the top can enter the plates 15 at different heights. The oil in the plates 15 can be screened by the filter screen plate 17. Finally, it is transported to the external drain pipe 6 through the bend pipe 16 at the bottom of the plates 15 to discharge the oil.
