Description

A refining device for producing aromatic solvents Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a refining device for producing aromatic hydrocarbon solvents. Background Art

[0002] Aromatic solvents are a class of organic solvents widely used in the chemical industry, typically composed of compounds containing aromatic ring structures. These solvents typically exhibit good solubility and volatility, making them suitable for dissolution, extraction, and cleaning operations in many industrial processes. However, during the production and refining of aromatic solvents, distillation is required. To ensure the production quality of aromatic solvents, a refining device for their production is required.

[0003] After searching, the existing Chinese patent announcement number is: CN219897093U, which provides an aromatic hydrocarbon solvent distillation mechanism. This patent introduces hydraulic oil into the hydraulic cylinder through an oil pump, so that the output end of the hydraulic cylinder drives the mounting plate to move downward, and the mounting plate then drives the cylinder, connecting rod and universal wheel and other components to move downward. When the universal wheel is completely in contact with the ground, the oil pumping can be stopped to push the equipment forward to realize the transfer of the equipment. The damper and spring can play a shock-absorbing role during the movement, which can effectively reduce the vibration amplitude of the equipment.

[0004] Although the above patent can facilitate the development of equipment, the above-mentioned aromatic solvent distillation mechanism still has the following problems: when the aromatic solvent is distilled, the solvent may be unevenly mixed, resulting in local temperatures being too high or too low, causing local coking or crystallization of the solvent, thereby affecting the quality of the aromatic solvent.

[0005] In view of the above problems, a refining device for producing aromatic solvents is proposed.

A valve 20 is provided on the right side of the liquid outlet pipe 18. The liquid outlet pipe 18 is opened by rotating the valve 20, and the aromatic solvent is output from the tank body 1 through the fixed pipe 19. Evenly distributed support rods 21 are fixedly connected to the bottom of the tank body 1. The support rods 21 are used to support the equipment as a whole. Anti-slip pads 22 are fixedly connected to the bottom of the support rods 21. The anti-slip pads 22 are used to increase the friction between the support rods 21 and the ground, thereby improving the stability of the equipment.

[0035] In conjunction with Figure 1-3, the top of the tank body 1 is fixedly connected to a first servo motor 4, and the output end of the first servo motor 4 is fixedly connected to a fixed rod 5. The outer ring of the fixed rod 5 is fixedly connected to two stirring blades 6. When the first servo motor 4 is started, the two stirring blades 6 on the outer wall of the fixed rod 5 are driven to rotate, so as to stir and mix the raw materials. The top of the outer ring of the fixed rod 5 is fixedly connected to a driving gear 7. When the fixed rod 5 rotates, the driving gear 7 is driven to rotate. The top of the inner wall of the tank body 1 is rotatably connected to a driven gear 8, and the driving gear 7 is meshed with the driven gear 8. The driving gear 7 drives the driven gear 8 to rotate by rotation. The top of the inner wall of the tank body 1 is rotatably connected to an inner ring gear 9, and the inner wall of the inner ring gear 9 is meshed with the driven gear 8. The outer wall of the inner ring gear 9 is fixedly connected to a stirring frame 10, and the stirring frame 10 is rotatably connected to the bottom end of the fixed rod 5. The driven gear 8 drives the inner ring gear 9 to rotate by rotation, so that the inner ring gear 9 drives the stirring frame 10 to rotate, thereby further stirring and mixing the raw materials.

[0036] In conjunction with Figures 1, 2 and 4, water inlet components are provided on both sides of the tank body 1, and the water inlet components include a water inlet pipe 11, which passes through the tank body 1 and is fixedly connected. The two water inlet pipes 11 are rotatably connected to a connecting block 12 at one end relative to each other, and water is input to the connecting block 12 through the water inlet pipe 11.

[0037] Working principle: When producing and refining aromatic solvents, the raw materials are first input into the tank body 1 through the liquid inlet pipe 2 for distillation. During the distillation process, the first servo motor 4 is started to drive the two stirring blades 6 on the outer wall of the fixed rod 5 to rotate to stir and mix the raw materials. When the fixed rod 5 rotates, it drives the driving gear 7 to rotate, thereby driving the driven gear 8 to rotate, and then driving the inner ring gear 9 to rotate.

After the distillation is completed, the valve 20 is turned to open the liquid outlet pipe 18, and the aromatic solvent is output from the tank body 1 through the fixed pipe 19. When the work is completed, the water source is input into the connecting block 12 through the water inlet pipe 11, and then sprayed from the high-pressure nozzle 14 through the connecting pipe 13 to clean the inner wall of the tank body 1. At the same time, the second servo motor 15 is started to drive the bevel gear 16 to rotate, thereby driving the bevel gear ring 17 to rotate, and then driving the connecting block 12 to rotate.
