After the device completes the purification of the original liquid, the cold gas can enter the interior of the dynamic purification cylinder 1, so that the purification cylinder 1 can be quickly cooled down.

[0028] An air inlet pipe 9 is disposed at the upper end of the cylinder cover 3, a condenser pipe 10 is disposed on the surface of the air inlet pipe 9, the air inlet pipe 9 penetrates the condenser pipe 10, and a vacuum pump 12 is disposed at the top of the air inlet pipe 9;

[0029] When the device is in use, the purification cylinder 1 is heated to convert impurities in the raw liquid whose melting point is lower than that of the raw liquid into gas. At this time, the vacuum pump 12 is turned on to start pumping air to suck the gas converted from the impurities and the gas originally in the purification cylinder 1 into the air inlet pipe 9 and pass through the condenser 10. At this time, the gas converted from the impurities is cooled by the condenser 10 and turns back into liquid and flows into the storage bin 13, so as to discharge the impurities and purify the raw liquid.

[0031] When the device is in use, since the original air inside the purification cylinder 1 cannot be converted into liquid, the exhaust hole 11 is opened at this time to discharge the original air to speed up the purification speed of the original liquid inside the purification cylinder 1.

[0032] The sides of the cylinder cover 3 and the purification cylinder 1 are provided with a mounting block 18, and the upper end of the mounting block 18 is provided with a mounting screw 19, and the mounting screw 19 passes through the mounting block 18;

[0036] When the device is in use, the heating tube 4 is energized to make it start to heat up, so as to heat the purification tube 1. At this time, the contact area between the purification tube 1 and the heating tube 4 is a heat-conducting material, so that the heating tube 4 can better heat the inside of the purification tube 1 to purify the raw materials.

[0038] When the device is in use, after the raw liquid enters the interior of the purification cylinder 1, the drive motor 17 is turned on to drive the stirring rod 23 to rotate, and the raw liquid is stirred by the stirring rod 23 so that the raw liquid can be heated more evenly, thereby improving the efficiency of purification. When the purification is completed, the valve 21 is opened to discharge the purified raw liquid through the liquid outlet 22.

[0039] When the utility model is in use, firstly, the isocyanate propyl triethoxysilane stock solution is injected into the interior of the filter bin 14 through the liquid inlet 15, so as to filter the dust particles in the stock solution through the filter screen 16, and then the stock solution enters the interior of the purification cylinder 1, and at this time, the heating tube 4 is turned on to be energized to make the heating tube 4 heat the purification cylinder 1, and at the same time, the driving motor 17 is turned on to drive the stirring rod 23 to rotate, so that the stirring rod 23 stirs the stock solution, so that the stock solution can be better heated.
