The included angle between the heating plate 8 and the horizontal plane is 30 degrees.
The surface of the heating plate 8 is a smooth plane.
When light oil and heavy oil in the dewatered coal tar need to be separated, firstly, the dewatered coal tar is added into the heater 2, and the power supply of the heater 2 is switched on, so that the dewatered coal tar in the heater 2 is heated. Since light oil has a lower boiling point than heavy oil, light oil generates small bubbles during heating, and the generated small bubbles of light oil are collected on the inverted V-shaped bar 12, and when the small bubbles of light oil are combined together, they spread upward along the inverted V-shaped bar 12 until they spread to the vertical bar 13 on the top of the V-shaped bar.
Meanwhile, the power supply of the distillation power mechanism 5 is switched on, so that the connecting rod 14 is driven to move up and down, and meanwhile, under the action of the second elastic piece 17, so that the second sliding block 16 moves up and down, and further the inverted V-shaped rod 12 moves up and down, and further the vertical rod 13 is driven to move up and down, so that the two adjacent vertical rods 13 are in contact connection, then light oil small bubbles on the vertical rod 13 below can stretch to the vertical rod 13 above, until the light oil small bubbles stretch upwards, until the light oil vapor is evaporated, and then the light oil vapor is discharged through the first air outlet pipe 3. Because first outlet duct 3 is connected with the condenser pipe, consequently the light oil steam that discharges through first outlet duct 3 meets the cold and will condense into light oil solution to collect it, thereby make light oil and heavy oil separate.
After the light oil solution in the heater 2 is boiled, the generated bubbles are large, so that the large bubbles directly spread to the vertical rod 13 along the inverted V-shaped rod 12, and then are evaporated into light oil vapor, and then the steps are repeated, so that the light oil solution is collected, and finally the light oil and the heavy oil are separated.
When the light oil and the heavy oil in the dewatering coal tar in the heater 2 are separated almost, the discharging mechanism 6 is driven, and the power supply of the heating plate 8 is switched on simultaneously, so that the dewatering coal tar in the heater 2 is slowly discharged and then flows onto the heating plate 8, and then the light oil is evaporated through the heating of the heating plate 8 and then is discharged through the second air outlet pipe 4. Because second outlet duct 4 also is connected with the condenser, consequently also can condense into light oil solution, later collect it again, the removal coal tar that flows down through hot plate 8 will enter into in the case 9 that gathers materials through funnel 10 simultaneously.
Meanwhile, the distillation power mechanism 5 can drive the driving mechanism 7 to work, so that the heating plate 8 is driven to move left and right, the contact area between the heating plate 8 and the dewatering coal tar is enlarged, more light oil in the dewatering coal tar is in contact with the heating plate 8, and the light oil and the heavy oil are separated more thoroughly. At the same time, the left and right movement of the heating plate 8 can cause the coal tar removed on the heating plate 8 to flow down more quickly.
And when all the dewatered coal tar in the heater 2 is discharged, closing the discharging mechanism 6. Then the power supply of the liquid pumping mechanism 11 is switched on, so that the dewatered coal tar in the material collecting box 9 is pumped into the heater 2, and then the steps are repeated, and light oil and heavy oil in the dewatered coal tar are separated, so that the dewatered coal tar is more thoroughly separated.
When the separation of light oil and heavy oil in the dewatered coal tar is finished, the power supplies of the distillation power mechanism 5, the liquid pumping mechanism 11, the heater 2 and the heating plate 8 are cut off, and meanwhile, the driving mechanism 7 stops working.

When the light oil and the heavy oil in the dewatering coal tar in the heater 2 need to be separated, the power of the motor 52 is switched on, and then the cam 54 is driven to rotate through the first rotating shaft 53, because the roller 55 and the first elastic piece 57 act, and then the lifting rod 510 is driven to move up and down, thereby the connecting rod 14 is driven to move up and down, thereby two adjacent vertical rods 13 are contacted and connected, thereby the light oil bubbles on the vertical rod 13 below are spread to the vertical rod 13 above, and the evaporation of the light oil is accelerated.
