A fluid channel is arranged between the VGO injection pipe and the hot high separation liquid outlet. The lower end of the VGO injection pipe is arranged outside the hot high separation liquid outlet. The upper end of the VGO injection pipe is arranged in the shell. The VGO injection pipe is arranged in a vertical direction. The upper end of the VGO injection pipe is located in the lower head. The upper end of the VGO injection pipe is A conical cylinder with the top facing upwards, a plurality of injection holes are distributed along the circumference of the conical cylinder and along the side wall of the conical cylinder, the VGO injection pipe is a SWT pipe, the inner surface or the outer surface of the VGO injection pipe is provided with a SS protective layer, the separator body 8 is a prior art, and the separator body 8 in the present application is an application of the prior art, the upper surface of the bottom plate 9 is fixed with a support frame 7 by bolts, both sides of the support frame 7 are provided with a slide groove 13, a first fixing ring 11 is slidably connected in the slide groove 13, the separator body 8 passes through the first fixing ring 11, and the separator The circumferential outer wall of the separator body 8 is provided with an adsorption component to support and position the separator body 8. A connecting frame 6 is welded to the top outer wall of the separator body 8. A guide shaft is fixed in the connecting frame 6 by bolts. A connecting rod 2 is rotatably connected to the top of the support frame 7. Two winding rollers 1 are fixed to the circumferential outer wall of the connecting rod 2 by bolts. The outer sides of the two winding rollers 1 are wound with the same pull rope 14. A avoidance groove 3 is opened on the top of the support frame 7. The pull rope 14 passes through the avoidance groove 3 and bypasses the guide shaft. A power group for driving the connecting rod 2 to rotate is provided on one side of the support frame 7. The power component drives the connecting rod 2 to rotate, the connecting rod 2 will drive the winding roller 1 to rotate, and the winding roller 1 will wind up the pull rope 14. Since the pull rope 14 bypasses the guide shaft on the connecting frame 6, the pull rope 14 will pull the connecting frame 6 to move upward through the guide shaft, and the connecting frame 6 will drive the separator body 8 to move upward. The separator body 8 will drive the first fixing ring 11 to move upward along the slide groove 13 through the adsorption component, so that the height of the separator can be adjusted, which is convenient for the installation of the separator and improves the convenience of separator installation.

[0023] The power assembly includes a connecting plate, which is welded to one side of the support frame 7 near the top. A motor is fixed to the bottom of the connecting plate by bolts. One end of the motor output shaft passes through the support frame 7 and is fixed with a worm 4 by bolts. One end of the connecting rod 2 passes through the support frame 7 and is keyed to a worm wheel 5, and the worm wheel 5 is meshed with the worm 4. The motor drives the worm 4 to rotate, the worm 4 drives the worm wheel 5 to rotate, and the worm wheel 5 drives the connecting rod 2 to rotate. When the separator body 8 moves to a suitable height, the motor is turned off. At this time, due to the meshing of the worm 4 and the worm wheel 5, the worm wheel 5 cannot drive the worm 4 to rotate, so the height of the separator body 8 can be fixed.

[0024] In the utility model, the adsorption component includes a magnetic ring 12, which is bonded to the outer side of the separator body 8. The magnetic ring 12 is adsorbed with the first fixed ring 11, and a plurality of plug rods 19 are bonded to the bottom of the magnetic ring 12. A plurality of slots 20 are provided on the top of the first fixed ring 11, and the plurality of plug rods 19 are respectively plugged into the plurality of slots 20. When the separator body 8 moves upward, the magnetic ring 12 is adsorbed with the first fixed ring 11, thereby driving the first fixed ring 11 to move upward. At the same time, since the plug rod 19 is inserted into the slot 20, the separator body 8 can be prevented from rotating. A plurality of rollers 10 are fixed to the bottom of the bottom plate 9 by bolts, and the rollers 10 facilitate the movement of the bottom plate 9.

[0025] In order to prevent the bottom plate 9 from moving during the installation of the separator body 8, a friction assembly is provided at the bottom of the bottom plate 9 to fix the bottom plate 9. The friction assembly includes two protrusions 17, which are welded to the bottom of the bottom plate 9. A connecting shaft is rotatably connected between the two protrusions 17. A fixing plate 16 is welded to the circumferential outer wall of the connecting shaft. A threaded rod 15 is rotatably connected to the upper surface of the fixing plate 16. A threaded hole is provided on the upper surface of the bottom plate 9. The threaded rod 15 is threadedly connected to the threaded hole. The threaded rod 15 is rotated and the threaded rod 15 is connected to the threaded hole. The threaded engagement will move downward, and the threaded rod 15 will push the fixing plate 16 to rotate downward through the connecting shaft, so that the fixing plate 16 is in close contact with the ground, increasing the friction of the movement of the bottom plate 9 and fixing the bottom plate 9. Both ends of the connecting shaft are welded with torsion springs 18 through the protrusions 17, and the torsion springs 18 are fixed to the protrusions 17. During the rotation of the fixing plate 16, the connecting shaft will cause the torsion spring 18 to generate torsion, and the torsion spring 18 can automatically reset the fixing plate 16. A knob for rotating the threaded rod 15 is welded at the top of the threaded rod 15.

[0026] Working principle: when it is needed, the motor drives the worm 4 to rotate, the worm 4 drives the worm wheel 5 to rotate, the worm wheel 5 drives the connecting rod 2 to rotate, the connecting rod 2 drives the winding roller 1 to rotate, and the winding roller 1 winds the pull rope 14. Since the pull rope 14 bypasses the guide shaft on the connecting frame 6, the pull rope 14 will pull the connecting frame 6 upward through the guide shaft, and the connecting frame 6 will drive the separator body 8 to move upward. The separator body 8 will drive the first fixed ring 11 to move upward along the slide groove 13 through the adsorption of the magnetic ring 12 and the first fixed ring 11. When the separator body 8 moves to a suitable height, the motor is turned off. At this time, due to the meshing of the worm 4 and the worm wheel 5, the worm wheel 5 cannot drive the worm 4 to rotate. Therefore, the height of the separator body 8 can be fixed, thereby adjusting the height of the separator, facilitating the installation of the separator, and improving the convenience of separator installation.
