When in use, the crude oil is introduced into the demagnetizing cylinder 21 from the crude oil inlet and then flows out from the crude oil outlet. During the process, the crude oil flows through multiple demagnetizers 2, and the magnetic core 3 in the demagnetizer 2 demagnetizes the crude oil. The utility model uses multiple demagnetizers 2 in series, so that the raw material can be repeatedly demagnetized through multiple magnetic cores 3 to improve the demagnetization effect.

[0031] Among them, as attached Figures 6 to 8 As shown, the magnetic core 3 includes a bracket 31, a fixing plate 32, a permanent magnet rod 33 and a fixing cover plate 34. A plurality of fixing plates 32 are provided on the bracket 31. A plurality of permanent magnet rods 33 are respectively placed in holes 321 of the fixing plates 32. A fixing cover plate 34 is provided on the upper surface of the uppermost fixing plate 32. The fixing cover plate 34 covers the top of the permanent magnet rods 33. When the crude oil flows through a plurality of demagnetizers 2, the permanent magnet rods 33 in the magnetic core 3 will demagnetize the crude oil.

[0032] It is worth mentioning that Figures 5 to 10 As shown, the magnetic core 3 is detachably placed in the demagnetizing cylinder 21.

When cleaning, the flange cover 24 is removed, the tube mouth of the demagnetizing cylinder 21 is opened, and then the magnetic core 3 can be taken out of the demagnetizing cylinder 21 as a whole for cleaning.

When in use, the high-temperature heat transfer oil is introduced into the housing 1 from the heat transfer oil inlet 13, and then flows out from the heat transfer oil outlet 14 of the housing 1. During the process, the heat transfer oil heats the raw oil to prevent the raw oil from condensing. At the same time, a heat transfer oil drain port 15 is provided at the bottom end of the outer wall of the housing 1, and the heat transfer oil drain port 15 is connected to the heat transfer oil outlet 14. The heat transfer oil drain port 15 is used to drain the heat transfer oil in the housing 1.
