[0014] This invention provides a resin filling device. A heating plate heats the resin inside a heating cylinder, and an infrared temperature sensor monitors the resin temperature. A controller adjusts the heating power of the heating plate based on the resin temperature. A pressurizing pump and pipe inject air into the heating cylinder, increasing the pressure and allowing the resin to be injected into the exchange column via resin conduits and filling pipes. A water injection mechanism fills the exchange column with water, preventing direct impact from the resin on the bottom of the device and the water distribution system during filling, thus preventing damage. A strip-shaped opening allows the connecting pipe to extend to the outside of the housing. A limiting rod guides and limits the lifting plate. A water pump draws water from the tank and pumps it through a water pipe. The three-way pipe, connecting pipe, and water injection pipe are filled with water to about 1 / 3 of their height.

Air is injected into the heating cylinder through a pressurizing pump and pressurizing pipe, thereby increasing the air pressure in the heating cylinder. This allows the resin in the heating cylinder to be injected into the exchange column along the resin conduit and filling pipe. The air in the negative pressure box is extracted by a negative pressure pump and negative pressure pipe, creating a negative pressure in the negative pressure box. This allows the rising water in the exchange column to be drawn into the negative pressure box. The water in the negative pressure box can be drained through the drain pipe and drain valve. The device can be operated and controlled by a controller. Attached Figure Description

A first one-way valve 25 is provided on the pressure pipe 24. An infrared temperature sensor 26, model W-TRS-5.5, is provided on the inner wall of the top of the heating cylinder 1.

[0027] The working principle of the resin filling device provided by this utility model is as follows:
[0028] The filling seat 5 is installed on the exchange column. The heating plate 2 is activated to heat the resin in the heating cylinder 1. The temperature of the resin in the heating cylinder 1 can be monitored by the infrared temperature sensor 26. The controller controls the heating power of the heating plate 2 according to the temperature of the resin in the heating cylinder 1. The water pump 18 is activated, and the water pump 18 draws water from the water tank 17 and injects water to about 1 / 3 of the height through the water guide pipe 19, the three-way pipe 16, the connecting pipe 15 and the water injection pipe 13. The purpose of this is to prevent the resin from directly impacting the bottom of the equipment and the water distribution device during the filling process, which would cause damage. It also helps to distribute the resin evenly. The water level in the exchange column can be indirectly monitored by the radar level sensor 14. The servo motor 10 is activated, and the servo motor 10 drives the screw 11 to rotate. 1. Rotating the lifting plate 12 and the water injection pipe 13 causes them to move up and down, thereby moving the bottom end of the water injection pipe 13 to the target position for resin filling. 2. The negative pressure pump 27 is started. The negative pressure pump 27 extracts the air from the negative pressure box 20 through the negative pressure pipe 28, thereby creating a negative pressure in the negative pressure box 20. 3. The pressurizing pump 23 is started. The pressurizing pump 23 injects air into the heating cylinder 1 through the pressurizing pipe 24, thereby increasing the air pressure in the heating cylinder 1. This causes the resin in the heating cylinder 1 to be injected into the water in the exchange column along the resin conduit 3 and the filling pipe 6, causing the water level to rise. As the water level rises, the water enters the negative pressure box 20 along the water injection pipe 13, the connecting pipe 15, the tee pipe 16, and the suction pipe 21 until the filled resin contacts the bottom end of the water injection pipe 13, and all the water in the exchange column is extracted, thus completing the resin filling.
[0029] Compared with related technologies, the resin filling device provided by this utility model has the following beneficial effects:
[0030] This invention provides a resin filling device. A heating plate 2 heats the resin inside a heating cylinder 1. An infrared temperature sensor 26 monitors the resin temperature inside the heating cylinder 1. A controller adjusts the heating power of the heating plate 2 based on the resin temperature inside the heating cylinder 1. A pressurizing pump 23 and a pressurizing pipe 24 inject air into the heating cylinder 1, thereby increasing the air pressure inside the heating cylinder 1. This allows the resin inside the heating cylinder 1 to be injected into the exchange column along the resin conduit 3 and the filling pipe 6. A water injection mechanism can inject water into the exchange column, preventing the resin from directly impacting the bottom of the equipment and the water distribution device during the filling process, thus preventing damage. A strip-shaped opening 8 allows the connecting pipe 15 to extend to the outside of the housing 4. A limiting rod 9 guides and limits the lifting plate 12. A water pump 18 draws water from the water tank 17 and through the water guide pipe 19 and a tee. Water is injected into pipe 16, connecting pipe 15, and water injection pipe 13 to a height of about 1 / 3. This is to prevent the resin from directly impacting the bottom of the equipment and the water distribution device during the filling process, which could cause damage. It also helps to distribute the resin evenly. The water level in the exchange column can be indirectly monitored by the radar level sensor 14. Air is injected into the heating cylinder 1 by the pressurizing pump 23 and pressurizing pipe 24, thereby increasing the air pressure in the heating cylinder 1. This allows the resin in the heating cylinder 1 to be injected into the exchange column along the resin conduit 3 and filling pipe 6. The air in the negative pressure box 20 is extracted by the negative pressure pump 27 and negative pressure pipe 28, thereby creating a negative pressure in the negative pressure box 20. This allows the rising water in the exchange column to be drawn into the negative pressure box 20. The water in the negative pressure box 20 can be discharged through the drain pipe 30 and drain valve 31. The device can be operated and controlled by the controller 30.
