A wire is used to connect the terminal post with an external power supply, and current flows into the resistance heating wire through the terminal post. The resistance heating wire heats the connecting rubber strip, and the connecting rubber strip is softened by heat. The softened connecting rubber strip will adhere the guide tube to the feed port of the ion exchange resin tower. Then, the connection between the terminal post and the external power supply is disconnected, and the resistance heating wire no longer heats the connecting rubber strip. The connecting rubber strip is cooled and solidified, and the solidified connecting rubber strip fixes the guide tube on the feed port of the ion exchange resin tower. The vacuum pump is started, and the vacuum pump passes the ion exchange resin through the guide tube. The air in the lipid tower is extracted, and a negative pressure environment is formed in the ion exchange resin tower. When the vacuum degree in the ion exchange resin tower reaches the specified threshold, the sealing plug in the filling tube is pulled out and the filling tube is placed in the ion exchange resin box. The stop valve is opened, and the ion exchange resin enters the ion exchange resin tower along the filling tube and the guide tube under the action of air pressure, thereby completing the filling of the ion exchange resin. During use, there is no need to add water, and the ion exchange resin will not be under pressure to affect its service life. This solves the problem that the existing resin filling device generally uses a pneumatic diaphragm pump or a water ejector to fill the resin, which requires a large amount of clean water, resulting in the need for subsequent neutralization method to treat the wastewater, and the operation is cumbersome.
