DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: A crude oil processing device for light white oil refining, see Figure 1-Figure 5 , including a bracket 1, a distillation tank 2, a drain pipe 201, an electronic valve I 202, a liquid inlet pipe 3, an electronic valve II 4, a cover plate 6, a three-way pipe 10, a connecting pipe 11, an exhaust pipe 12 and a cooling mechanism. The bracket 1 is fixedly connected to the distillation tank 2, the bottom of the distillation tank 2 is connected and communicated with the drain pipe 201, the drain pipe 201 is provided with an electronic valve I 202, one side of the distillation tank 2 is connected and communicated with the liquid inlet pipe 3, the liquid inlet pipe 3 is provided with an electronic valve II 4, and the upper end of the liquid inlet pipe 3 is connected The top of the distillation tank 2 is connected and connected with an exhaust pipe 12, and a cooling mechanism is provided on the exhaust pipe 12. A condenser 13 is provided on the exhaust pipe 12 by means of bolts. The bottom of the condenser 13 is connected to two condensing pipes 14, which are wound around the exhaust pipe 12. A heating box 5 is fixedly connected to the top, and a three-way pipe 10 is located inside the heating box 5. The heating box 5 is covered with a cover plate 6. A heater 7 is provided on the top of the cover plate 6 by bolt connection. Two heating pipes 8 are connected to the front and back sides of the heater 7. The heating pipe 8 extends to the inside of the heating box 5. An electric heating network 9 is provided inside the heating box 5, and the electric heating network 9 is located below the heating pipe 8. Four anti-slip pads 22 are embedded in the bottom of the bracket 1. The anti-slip pads 22 increase the friction between the bottom of the bracket 1 and the ground, thereby preventing the bracket 1 from moving. A protective shell 23 is provided on the exhaust pipe 12, and the protective shell 23 wraps the condenser pipe 14 to protect the condenser pipe 14. The lower end of the exhaust pipe 12 is connected and connected to a filter pipe 24. An activated carbon plate 25 is embedded in the filter pipe 24. The filter pipe 24 filters the liquid and then sieves out impurities carried in the liquid. At the same time, the activated carbon plate 25 absorbs the odor in the liquid to avoid direct emission of odor and pollution to the environment.

[0028] When the present device is to be used, the oil inlet pipe is first connected to the connecting pipe 11. Next, the heater 7 and the electric heating network 9 are turned on. When crude oil flows into the three-way pipe 10, the heater 7 controls the heating pipe 8 to generate heat, and the electric heating network 9 also generates heat, which in turn acts on the three-way pipe 10 to heat the crude oil inside the three-way pipe 10. Since the viscosity of most crude oils decreases with increasing temperature, increasing the temperature of the crude oil can reduce its viscosity, thereby accelerating the flow of crude oil and improving the efficiency of crude oil processing. Subsequently, the electronic valve I 202 is opened to allow the heated crude oil to enter the distillation tank 2. When the distillation tank 2 is filled with the required amount of crude oil, the electronic valve I 202 is closed, and the distillation tank 2 is started to process the crude oil. The gas generated during refining is discharged through the exhaust pipe 12. At this time, the condenser 13 is turned on to operate the condenser 14. The gas is cooled back to liquid by the cooling water circulation inside the condenser 19, and the liquid material is then discharged through the exhaust pipe 12. After refining is completed, the electronic valve I is opened to allow the light white oil to be discharged through the drain pipe 201.

[0029] Example 2: Based on Example 1, please refer to Figure 2 and Figure 3 A support plate 15 is fixedly connected to the upper part of the distillation tank 2, a temperature detector 16 is provided at the bottom of the support plate 15 by means of bolt connection, a pressure detector 17 is provided at the bottom of the support plate 15 by means of bolt connection, and a display screen 18 is provided on the support plate 15.

[0030] When crude oil is being processed, the temperature detector 16 and the pressure detector 17 are turned on. The temperature detector 16 monitors the temperature inside the distillation tank 2 in real time, and the pressure detector 17 detects the pressure change inside the distillation tank 2. The detected data is displayed on the display screen 18, thereby improving the safety of the operation.

[0031] See also Figure 3 、 Figure 4 and Figure 5 Six card rods 19 are fixedly connected to the three-way pipe 10, and a filter basket 20 is slidingly arranged inside the three-way pipe 10. The filter basket 20 can rotate inside the three-way pipe 10. The top of the filter basket 20 is an inclined surface. The crude oil entering the three-way pipe 10 passes through the filter basket 20, and the inclined surface on the top of the filter basket 20 filters and intercepts the crude oil. Six card blocks 21 are fixedly connected to the outside of the filter basket 20. The card blocks 21 are provided with card slots matching the card rods 19. The card rods 19 are inserted into the card slots to limit the filter basket 20. When the filter basket 20 needs to be cleaned or replaced, the filter basket 20 is rotated to disengage the card blocks 21 from the card rods 19, and the limited filter basket 20 is no longer limited. The filter basket 20 is then pulled downward to remove the filter basket 20 from the inside of the three-way pipe 10 for cleaning or replacement.

[0032] After the crude oil enters the connecting pipe 11, it flows into the three-way pipe 10. During this process, the filter basket 20 filters the large particles carried in the crude oil, thereby screening out the large particles and improving the purity of the crude oil. The filtered crude oil enters the liquid inlet pipe 3 through the three-way pipe 10 and finally flows into the distillation tank 2.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
