[0002] Solvent is a compound that can dissolve other substances. It is often used to dissolve solid, liquid or gaseous substances into liquid form. Solvent recovery device is a device used to recover and reuse used solvents. In industrial production and laboratory operations, solvents are usually used to dissolve or treat substances, but the used solvents may contain impurities or other pollutants. In order to improve resource utilization efficiency, reduce costs and reduce environmental pollution, solvent recovery devices are designed to clean and regenerate used solvents to meet the standards for reuse.

[0003] After searching the Chinese patent document with the announcement number CN206935275U, a solvent recovery device is disclosed, which includes a primary liquid storage tank, a vacuum machine, an emptying pipe, and a secondary liquid storage tank.

The top of the primary liquid storage tank is connected to the top of the secondary liquid storage tank through a conduit. The conduit is also connected to a vacuum machine. A one-way valve is fixed on the conduit between the vacuum machine and the primary liquid storage tank. The top of the secondary liquid storage tank is also fixed with an emptying pipe, which is a telescopic pipe, and the pipe mouth of the emptying pipe is covered with a screen. The utility model can reduce the boiling temperature of the solution, and can discharge alcohol and excess gas from the primary liquid storage tank. Under the action of the 15-meter emptying pipe, the alcohol falls into the secondary liquid storage tank due to the insufficient rising force of the alcohol vapor. The fixed telescopic emptying pipe is easy to clean and maintain, and the fixed screen prevents birds from entering the emptying pipe or rainwater from entering.

The fixing ring 13 is fixed by a plurality of support rods 14, and the fixing ring 13 fixes the cylinder 9. The rotating disc 15 drives the threaded column 16 and the filter cylinder 17 to rotate, thereby completing the installation. After the solvent mixture is filtered by the filter cylinder 17, it flows outward from the inside of the filter cylinder 17 into the internal space of the cylinder 9, and then flows into the distillation component through the porous bottom plate 18 via the discharger 7. By energizing the heating component, the heating component generates heat and transfers the heat to the water inside the heating component. The water will evenly heat the distillation component, thereby completing the distillation. Through filtration and distillation purification, the pure solvent gas flows through the output pipe 10 to the collecting bottle 11, and is condensed by the condenser in the process, so that it is stored in the collecting bottle 11 in the form of liquid. This process first realizes the pretreatment of the solvent mixture, so that large particles, suspended matter and other substances will not enter the recovery device together, and the inside of the device is difficult to be blocked. Then, the solvent is further purified through distillation, which greatly improves the solvent recovery efficiency.

The bottom of the distillation flask 4 is arranged inside the water tank 3, and the inside of the water tank 3 is filled with water. The bottom surface of the collecting bottle 11 is fixedly connected to the top surface of the bottom plate 1. The distillation tube 5 and the distillation flask 4 will receive the solvent from the discharger 7, and generate heat by energizing the heating plate 2, which is then transmitted to the water tank 3, so that the water in the water tank 3 is heated up, thereby heating the distillation flask 4, and pure solvent gas will flow through the output pipe 10. The control valve 8 is used to control the flow rate and switch of the solvent. The function of the pressure valve 6 is to prevent the internal expansion of the device caused by heating, and it can release air.

When the threaded column 16 is completely screwed into the inside of the threaded hole, the bottom surface of the disc 15 is attached to the top surface of the cylinder 9.

The bottom of the distillation bottle 4 is arranged in the interior of the water tank 3. There is water in the water tank 3. By energizing the heating plate 2, heat is generated and transmitted to the water tank 3, so that the water in the water tank 3 is heated, thereby heating the distillation bottle 4, and the pure solvent gas flows through the output pipe 10 to the collecting bottle 11. In the process, it is condensed by the condenser, and is stored in the collecting bottle 11 in the form of liquid. This process realizes the pretreatment of the solvent mixture, so that large particles, suspended matter and other substances will not enter the recovery device together, and the interior of the device is difficult to be blocked, thereby improving the solvent recovery efficiency.
