Description

Technical Field

[0001] This utility model relates to the field of aromatic distillation technology, specifically to an environmentally friendly aromatic solvent distillation and refining apparatus. Background Technology

[0002] Aromatic hydrocarbons are a common chemical reagent widely used in industries such as paints, printing, inks and resins. Distillation is an essential step in the preparation of aromatic hydrocarbons. During the distillation process, the components of the raw materials are separated based on their different degrees of volatility.

[0003] Existing aromatic hydrocarbon distillation and purification devices require external cooling water for condensation during practical use, which makes it inconvenient to recycle the cooling water and is not energy-efficient or environmentally friendly. Therefore, we propose an environmentally friendly aromatic hydrocarbon solvent distillation and refining device. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly distillation and refining device for aromatic solvents, in order to solve the problem that the existing aromatic distillation and purification devices mentioned in the background art require external cooling water for condensation during actual use, which is inconvenient for recycling the cooling water and is not energy-saving and environmentally friendly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly aromatic solvent distillation and refining device, comprising a distillation tank and a receiving tank fixed on the surface of a bottom plate for aromatic purification, a condenser tube provided between the distillation tank and the receiving tank, a water supply assembly and a heating assembly fixed on the top and bottom of the distillation tank located below the condenser tube on the surface of the bottom plate.

[0006] Preferably, the water supply assembly includes a water tank, a support plate, a thermoelectric cooler, a control panel, and a miniature transformer. The water tank is fixedly connected to the surface of the base plate below the condenser tube. The surface of the water tank is connected to the inlet and outlet of the condenser tube via flexible hoses. A water pump is installed inside the water tank. A support plate is embedded on one side of the water tank. Equidistant thermoelectric coolers are installed on the inner side of the support plate, with the cold end of the thermoelectric cooler located inside the water tank. A control panel is installed on the outer side of the water tank. The output end of the control panel is electrically connected to the miniature transformer, and the other end of the miniature transformer is connected in series with the thermoelectric cooler.

[0007] Preferably, the heating assembly includes a heating rod, a switch button, a mounting plate, and a fixing block. The top and bottom of the distillation tank are both fitted with mounting plates. The heating rod is installed at one end of the mounting plate inside the distillation tank. The switch button is installed on the outside of the mounting plate. The switch button and the heating rod are electrically connected. The other end of the heating rod is snapped with a fixing block, which is fixedly connected to the inner wall of the distillation tank.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. This utility model uses a water tank, a support plate, a semiconductor cooling chip, a control panel, and a miniature transformer in combination. The water tank is set below the condenser tube on the surface of the base plate. The inlet and outlet of the water tank and the condenser tube are connected to achieve the effect of circulating cooling water. During the condensation operation, the semiconductor cooling chip is activated by the voltage regulation of the miniature transformer on the surface of the water tank. The cold end of the semiconductor cooling chip cools the water in the water tank, and then the water is pumped into the condenser tube for use by the water pump in the water tank, which facilitates the condensation operation.

[0010] 2. This utility model uses a combination of a heating rod, a switch button, a mounting plate, and a fixing block. A switch button is installed at the top of the distillation tank, connecting to the heating rod. The heating rod at the bottom of the distillation tank heats the aromatic solvent, while the heating rod at the top of the distillation tank provides auxiliary heating for the aromatic gas that has evaporated to the top. Simultaneously, it heats the contact point between the distillation tank and the condenser tube, preventing the aromatic gas from undergoing a state change due to temperature drop when it reaches the top of the distillation tank or the contact point between the distillation tank and the condenser tube, thus ensuring the distillation effect of the aromatics.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figures 1-3The diagram illustrates an environmentally friendly aromatic solvent distillation and refining apparatus, comprising a distillation tank 6 and a receiving tank 2 fixed to the surface of a base plate 1 for aromatic purification. A condenser pipe 3 is provided between the distillation tank 6 and the receiving tank 2. A water supply assembly and a heating assembly 5 fixed to the top and bottom of the distillation tank 6 are located on the surface of the base plate 1 below the condenser pipe 3. The water supply assembly includes a water tank 4, a support plate 7, a semiconductor refrigeration chip 8, a control panel 9, and a miniature transformer 10. The water tank 4 is fixedly connected to the surface of the base plate 1 below the condenser pipe 3. The surface of the water tank 4 is connected to the inlet and outlet of the condenser pipe 3 via flexible hoses. A water pump is installed inside the water tank 4. A support plate 7 is embedded on one side of the water tank 4. Equally spaced thermoelectric coolers 8 are installed on the inner side of the water tank 4. The cold end of the thermoelectric cooler 8 is located inside the water tank 4. A control panel 9 is installed on the outer side of the water tank 4. The output terminal of the control panel 9 is electrically connected to a miniature transformer 10. The other end of the miniature transformer 10 is connected in series with the thermoelectric cooler 8. The water tank 4 is set below the condenser tube 3 on the surface of the base plate 1. The inlet and outlet of the water tank 4 and the condenser tube 3 are connected to achieve the effect of circulating cooling water. During the condensation operation, the thermoelectric cooler 8 is activated by the voltage regulation of the miniature transformer 10 on the surface of the water tank 4. The cold end of the thermoelectric cooler 8 cools the water in the water tank. Then, the water is pumped into the condenser tube 3 by the water pump in the water tank 4 for use, which facilitates the condensation operation.

[0017] Based on the aforementioned scheme, the heating assembly 5 includes a heating rod 501, a switch button 502, a mounting plate 503, and a fixing block 504. The top and bottom of the distillation tank 6 are both fitted with the mounting plate 503. The heating rod 501 is mounted on one end of the mounting plate 503 inside the distillation tank 6, and the switch button 502 is mounted on the outside of the mounting plate 503. The switch button 502 is electrically connected to the heating rod 501, and the fixing block 504 is snapped onto the other end of the heating rod 501. The fixing block 504 is fixedly connected to the inner wall of the distillation tank 6. A switch button 502 is installed on the top and bottom of the distillation tank 6, which is connected to a heating rod 501. The heating rod 501 at the bottom of the distillation tank 6 heats the aromatic solvent, while the heating rod 501 at the top of the distillation tank 6 provides auxiliary heating for the aromatic gas that has evaporated to the top. At the same time, it heats the contact point between the distillation tank 6 and the condenser 3, preventing the aromatic gas from undergoing a change in state due to a drop in temperature when it reaches the top of the distillation tank 6 or the contact point between the distillation tank 6 and the condenser 3. This ensures the distillation effect of the aromatics and also increases the refining efficiency.

[0018] It should be noted that this utility model is an environmentally friendly distillation and refining device for aromatic solvents. First, the aromatic solvent to be refined is injected into the distillation tank 6. The switch button 502 and control panel 9 are connected to an external power supply. The heating rod 501 at the bottom of the distillation tank 6 heats the aromatic solvent. The heated and boiling aromatic solvent evaporates and moves towards the top of the distillation tank 6. The heating rod 501 at the top of the distillation tank 6 provides auxiliary heating for the aromatic gas that has evaporated to the top. Simultaneously, it heats the contact point between the distillation tank 6 and the condenser tube 3 to prevent the aromatic gas from reaching the top of the distillation tank 6 or... When the distillation tank 6 and the condenser tube 3 are in contact, the temperature decreases, affecting the transformation of the aromatic gas state and increasing the refining efficiency. At the same time, the micro transformer 10 is controlled by the control panel 9 to adjust the voltage, which enables the semiconductor cooling chip 8 to work. The cold end of the semiconductor cooling chip 8 cools the water in the water tank. The control panel 9 then controls the water pump in the water tank 4 to draw the cooling water in the water tank 4 into the condenser tube 3 for condensation. After condensation, the refined aromatic solvent is stored in the receiving tank 2 (the distillation principle of the distillation tank 6 and the condensation principle of the condenser tube 3 are existing publicly available technologies).
