Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-3 , the present invention provides a technical solution: a separation and treatment device for tetrahydrofuran, including a processing tank 1 and a heat conduction rod 8. A diversion top plate 101 is arranged at the top of the processing tank 1, and the diversion top plate 101 is integrally arranged in an inclined shape. One side of the upper end of the inclined diversion top plate 101 is provided with a feed pipe 103, and one side of the lower end of the inclined diversion top plate 101 is provided with a diversion opening 102. One end of the bottom wall of the processing tank 1 extends with a recovery table 104. A positioning sleeve 9 is arranged in the middle of the top of the processing tank 1, and a transmission sleeve 4 is sleeved in the middle of the inner wall of the positioning sleeve 9. A heating rod 5 is arranged in the middle of the transmission sleeve 4. Side extension pipes 401 are arranged in an up-and-down arrangement around the outer wall of the transmission sleeve 4, and a stirring member 7 is installed inside the side extension pipe 401. A mounting bolt 402 is installed through the connection between the stirring member 7 and the side extension pipe 401. A heat conduction rod 8 is filled inside the stirring member 7. A driven gear 301 is sleeved outside the top wall of the transmission sleeve 4, and a motor-driven transmission gear 3 is engaged outside the driven gear 301; the recovery table 104 and the diversion opening 102 are in an up-and-down position matching relationship; support feet 2 are arranged at the bottom of the processing tank 1; a heating power supply 6 is installed on one side of the top of the processing tank 1, and an electrical connection is formed between the heating power supply 6 and the heating rod 5; the motor-driven transmission gear 3 forms a transmission structure with the transmission sleeve 4 through the driven gear 301, and the transmission sleeve 4 and the heating rod 5 are sleeved and connected in a concentric circle; the side extension pipe 401 forms a detachable structure with the stirring member 7 through the mounting bolt 402, and the stirring member 7 and the heat conduction rod 8 form a wrapping connection; the heat conduction rod 8 and the heating rod 5 are arranged adjacent to each other;

[0025] By using the heating member built in the middle and through the settings of the heat conduction rod 8 and the heating rod 5, heat can be transferred to the transmission sleeve 4, the side extension pipe 401 and the stirring member 7 to heat the mixture;

[0026] On the outer side of the top of the transmission sleeve 4, there are a driven gear 301 and a motor-driven transmission gear 3 engaged with each other. The driven gear 301 sleeved outside the transmission sleeve 4 drives the transmission sleeve 4 to rotate.

[0027] When the transmission sleeve 4 rotates and heats, it stirs the mixture, improves the fluidity and heating efficiency of the mixture during the heating process, stirs the tetrahydrofuran mixture, and enables it to remove water vapor in the evaporated gas during stirring, achieving efficient heating, sufficient stirring and effective separation of the mixture.

[0028] The diversion top plate 101 located at the top of the treatment tank 1 can come into contact with the steam when evaporation occurs. The condensed liquid can smoothly slide along the inclined surface of the diversion top plate 101 and then move to the diversion port 102 end to gather, facilitating the bucket placed on the recovery table 104 to collect and discharge the dropped liquid water.

[0029] Working principle: For this type of tetrahydrofuran separation and treatment device, first start the motor to drive the motor-driven transmission gear 3 at the top of the treatment tank 1 to rotate. The motor-driven transmission gear 3 drives the engaged driven gear 301 to rotate, thereby causing the transmission sleeve 4 on the inner wall of the driven gear 301 to rotate, synchronously driving the stirring member 7 outside to rotate. Then, the tetrahydrofuran mixture is put in from the feed pipe 103 end and enters the treatment tank 1, making the tetrahydrofuran mixture come into contact with the stirring member 7 in the stirring state. When the transmission sleeve 4 rotates and heats, it stirs the mixture, stirs the tetrahydrofuran mixture, and enables it to remove water vapor in the evaporated gas during stirring, making the water vapor float up and contact the diversion top plate 101 at the top. When the water vapor liquefies, the condensed liquid can smoothly slide along the inclined surface of the diversion top plate 101 and then move to the diversion port 102 end to gather, facilitating the bucket placed on the recovery table 104 to collect and discharge the dropped liquid water. The tetrahydrofuran mixture after heating and separation can be discharged and collected through the discharge pipe at the bottom.

[0030] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of by those skilled in the art within the technical scope disclosed by the present invention without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
