Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to a creosote oil extraction device. Background Technology

[0002] Creosote oil extraction equipment is a specialized device used to extract creosote oil from various raw materials (such as wood tar, coal tar, etc.). Creosote oil extraction equipment is also known as a vacuum distillation reactor, a type of equipment widely used in chemical laboratories and industries. It is mainly used for distillation separation or reaction under low pressure to reduce the decomposition of heat-sensitive substances or lower the boiling point. Under vacuum conditions, through constant temperature heating and thorough stirring by the stirring system, the material evaporates efficiently and rapidly. The creosote oil vapor is cooled by a high-efficiency condenser and then recovered into a collection bottle, thus completing the distillation process.

[0003] Patent document CN222341999U discloses a vacuum distillation device for a paste reaction vessel. It specifies that the device includes a reaction vessel with an inner cylinder inside. A spiral conveyor plate is rotatably mounted inside the inner cylinder, with its bottom end extending outside the inner cylinder. The beneficial effects of this invention are: by setting an inner cylinder within the reaction vessel and a spiral conveyor plate within it, the rotation of the spiral conveyor plate allows the paste from the bottom of the reaction vessel to be conveyed upwards through the inner cylinder, and then the paste falls from the top of the inner cylinder back into the reaction vessel. This not only provides a stirring effect on the paste, but also, due to the heating of the paste by the hot water flowing from top to bottom through the spiral tube, the temperature gradually decreases from top to bottom. The lower temperature at the bottom preheats the upward-flowing paste, and then the higher temperature at the top rapidly heats the paste, improving reaction efficiency.

[0004] However, the vacuum distillation device of the paste reactor in the aforementioned published literature mainly considers the rapid heating of the paste by the higher temperature at the top, which improves the reaction efficiency, but makes it inconvenient to cool down the liquid water collected inside the drain tank.

[0005] Therefore, it is necessary to develop a cooling mechanism to cool the liquid water collected inside the drain tank, so as to facilitate the subsequent reuse of the liquid water. Utility Model Content

[0016] 1. This utility model uses a cooling mechanism to cool the liquid water collected inside the drain tank. The water collected in the existing drain tank has a certain temperature, which makes it impossible to cool the water quickly. Therefore, this needs to be improved.

Since the branch pipe is internally connected to the flange interface, the liquid in the branch pipe is transported to the flange interface. The flange interface supplies water to the cooling water pipe, allowing the cooled water to be reused. The shielding net is used to shield unmelted ice and protect the water pump.

[0027] Please see Figure 1 and Figure 2A creosote oil extraction device includes: an extraction cylinder 1, a stirring motor 2, a stirring shaft 3, a heating strip 4, a feed end 5, a negative pressure pump 6, and a drain tank 15. The bottom of the extraction cylinder 1 is provided with a discharge trough 7, and a first solenoid valve 8 is installed on the inner wall of the discharge trough 7. A condenser pipe 9 is installed on the top of the extraction cylinder 1, and a cooling water pipe 10 is installed around the outer wall of the condenser pipe 9. A flange interface end 11 is provided on the outer wall of the cooling water pipe 10, and a ball valve-type drain pipe 12 is installed on the outer wall of the cooling water pipe 10. A platform 13 is installed on the outer wall of the extraction cylinder 1, and an extraction box 14 is located on the top of the platform 13. A drain tank 15 is also located on the top of the platform 13. The stirring motor 2 is located at the top of the extraction cylinder 1, and the output end of the stirring motor 2 is installed with the stirring shaft 3. The heating strip 4 is located on the inner wall of the extraction cylinder 1. The feed end 5 is located on the outer wall of the extraction cylinder 1, and one end of the feed end 5 extends into the interior of the extraction cylinder 1. The negative pressure pump 6 is located at the top of the extraction cylinder 1, and the suction end of the negative pressure pump 6 extends into the extraction cylinder 1. Inside the extraction cylinder, coal tar is first added to the extraction cylinder 1 through the feed end 5. Then, the feed end 5 is sealed by an external piston mechanism. The negative pressure pump 6 works to reduce the pressure inside the extraction cylinder 1, and the heating bar 4 heats the coal tar. The stirring motor 2 drives the stirring shaft 3 to rotate, making the heating uniform, thereby evaporating the creosote oil in the coal tar. The evaporated substance enters the condenser tube 9, and the flange interface end 11 is connected to the external water supply source. The external water supply source supplies cold water to the cooling water pipe 10 through the flange interface end 11, which condenses the evaporated substance into liquid and collects the creosote oil through the extraction box 14. The ball valve type drain pipe 12 is equipped with a ball valve inside, which can drain and replace the water in the cooling water pipe 10, because the water will absorb heat for a long time and the temperature will rise, requiring replacement. The drain tank 15 is used to collect the drained water. The first solenoid valve 8 works to allow the discharge trough 7 to flow for the discharge of used coal tar.

[0028] Please see Figure 2 and Figure 3The outer wall of the extraction cylinder 1 is equipped with a cooling mechanism to cool the liquid water collected inside the drain tank 15. The cooling mechanism includes an L-shaped support 16, an ice-holding frame 23, and a sealing plate 26. The L-shaped support 16 is located on the outer wall of the extraction cylinder 1. An electric telescopic rod 17 is installed at the bottom of the L-shaped support 16. A protective box 18 is installed at the output end of the electric telescopic rod 17. A rotary motor 19 is installed on the inner wall of the protective box 18. A matching groove 20 is provided on the inner wall of the protective box 18. A sealing ring 21 is installed on the inner wall of the matching groove 20. A connecting block 22 is installed at the output end of the rotary motor 19.

A connecting rod 25 is installed at the bottom of the bracket 16, and a sealing plate 26 is located at the bottom of the connecting rod 25. The water collected in the existing drain tank 15 has a certain temperature, which makes it impossible to cool the water quickly. Therefore, this needs to be improved. First, ice cubes are placed in the ice-holding tank 24. Then, the electric telescopic rod 17 works to move the protective box 18, and at the same time, it moves the ice-holding frame 23 into the water in the drain tank 15. This design is to avoid liquid splashing when adding ice cubes. Then, the rotary motor 19 works to drive the ice-holding frame 23 to flip in the water, so that ice cubes are added. At the same time, when the ice-holding frame 23 is not in use, it can be moved to the bottom of the sealing plate 26 to seal and protect the ice-holding tank 24.

[0029] Please see Figure 4 and Figure 5The bottom of platform 13 is equipped with a utilization mechanism for the secondary use of cooled liquid water. The utilization mechanism includes a water pump 27, a shielding net 30, an electrical control box 31, and a control panel 32. The water pump 27 is located at the bottom of platform 13, and a hose 33 is installed at the outlet of the water pump 27. A first flange connection plate 34 is installed on the outer wall of the hose 33. The inner wall of the drain tank 15 has a slot 28, and a second solenoid valve 29 is installed on the inner wall of the slot 28. The shielding net 30 is located on the inner wall of the drain tank 15 and is positioned above the slot 28. The electrical control box 31 is located on the outer wall of the drain tank 15, and the control panel 32 is located on the outer wall of the electrical control box 31. A branch pipe 35 is installed on the outer wall of the flange interface end 11, and one end of the branch pipe 35 extends into the interior of the flange interface end 11. A second flange connection plate 34 is installed on the outer wall of the branch pipe 35. The connecting plate 36 facilitates the reuse of liquid water after cooling. First, it connects the first flange connecting plate 34 and the second flange connecting plate 36, which connects the hose 33 to the branch pipe 35. Then, the second solenoid valve 29 in the slot 28 opens, and the cooled water in the drain tank 15 is discharged into the inlet pipe of the water pump 27 through the slot 28. The inlet pipe of the water pump 27 is located below the slot 28. The water pump 27 works to transport liquid to the branch pipe 35 through the hose 33. Since the branch pipe 35 is connected to the flange interface end 11, the liquid in the branch pipe 35 is transported to the flange interface end 11. The flange interface end 11 supplies water to the cooling water pipe 10, so that the cooled water can be reused. The shielding net 30 is used to shield the incompletely melted ice and protect the water pump 27.

[0030] Working principle: First, coal tar is added to the extraction cylinder 1 through the feed end 5. Then, the feed end 5 is sealed by an external piston mechanism. The negative pressure pump 6 operates to reduce the pressure inside the extraction cylinder 1, and the heating strip 4 heats the coal tar. The stirring motor 2 drives the stirring shaft 3 to rotate, ensuring uniform heating, thereby evaporating the creosote oil in the coal tar. The evaporated substance enters the condenser 9, and the flange interface 11 is connected to an external water supply. The external water supply supplies cold water to the cooling water pipe 10 through the flange interface 11, condensing the evaporated substance into a liquid and then... Extraction box 14 collects creosote oil, and the ball valve type drain pipe 12 is equipped with a ball valve inside, which can drain and replace the water in the cooling water pipe 10. Because the water absorbs heat for a long time, the temperature will rise and it needs to be replaced. Drain tank 15 is used to collect the discharged water. The first solenoid valve 8 is activated to allow the discharge trough 7 to flow for the discharge of used coal tar. The water collected in the existing drain tank 15 has a certain temperature, which makes it impossible to cool the water quickly. Therefore, this needs to be improved. First, ice is placed in the ice-waiting tank 24, and then the electric telescopic rod 17 is activated to drive the protective box. 18 moves, simultaneously moving the ice-holding frame 23 into the water in the drain tank 15. This design is to prevent liquid splashing when adding ice. Then, the rotary motor 19 operates, causing the ice-holding frame 23 to flip in the water, allowing ice to be added. When not in use, the ice-holding frame 23 can be moved under the sealing plate 26 to seal and protect the ice tank 24. This facilitates the reuse of the liquid water after cooling. First, the first flange connecting plate 34 is connected to the second flange connecting plate 36, connecting the hose 33 to the branch pipe 35. The groove 28... The second solenoid valve 29 opens, and then the cooled water in the drain tank 15 is discharged into the inlet pipe of the water pump 27 through the slot 28. The inlet pipe of the water pump 27 is located below the slot 28. The water pump 27 works to transport the liquid to the branch pipe 35 through the hose 33. Since the branch pipe 35 is connected to the flange interface 11, the liquid in the branch pipe 35 is transported to the flange interface 11. The flange interface 11 supplies water to the cooling water pipe 10, so that the cooled water can be reused. The shielding net 30 is used to shield the incompletely melted ice and protect the water pump 27.
