Technical Field
[0001] The utility model relates to the technical field of resin filling, in particular to a resin filling device. Background Art
[0002] After the chromatographic separation equipment has been running for a period of time, the chromatographic separation resin in its cabin will continue to accumulate due to material pollutants, and the resin layer will be gradually compressed during the production process, causing the pressure difference between the inlet and outlet of the chromatographic separation cabin to rise. When the pressure exceeds the warning value, the resin needs to be backwashed in vitro to remove pollutants and broken resin in the resin and loosen the resin layer. The backwashed resin needs to be refilled into the cabin. In the prior art, the resin is usually filled back into the resin container under the combined action of gravity and water pressure.
[0003] For example, the patent with publication number CN214051677U discloses a resin filling device, specifically, the water tank and the resin holding box are pre-filled, and then the water pump is turned on, the water in the water tank is pumped out by the water pump and the water is transported forward along the delivery pipe, and the water flows through the tee; when the water flows through the tee, a certain negative pressure is generated at the longitudinal section of the tee, and under the action of the pressure and the gravity of the resin particles, the resin particles in the resin holding box flow downward into the tee and enter the delivery pipe through the tee to be transported to the resin tower body together;
[0004] However, the hydraulic transport method requires a large amount of water, which requires drainage at a later stage and repeated filling of resin. In the process of filling the resin, a large amount of water is required for transportation again, which requires complicated resin filling and drainage work, which is time-consuming, labor-intensive and inefficient.

[0026] In the present embodiment, the tank body 2 is a resin backwash tank. After the resin is backwashed, the partition 32 is installed inside the tank body 2, so that the top of the tank body 2 is divided into a water injection chamber, and water is injected into the water injection chamber through the water injection pipe 31. Then, as the amount of water injected increases, or further combined with the fact that the height of the tank body 2 is higher than the height of the resin chamber 1, the resin is pushed out of the tank body 2 and discharged into the resin chamber 1 through the discharge assembly 4 under the conditions of gravity and pressure difference. There is no need to transport the resin with the help of a large amount of water, thereby avoiding the complicated operation of repeatedly draining and refilling the resin chamber 1, saving time and effort, and being extremely efficient.

[0029] In this embodiment, a protrusion 5 is extended from one end of the bucket body 321 away from the slider 322. The protrusion 5 is a hollow structure, which makes it easy to receive a larger volume of water to promote the discharge of resin. The sealing ring 22 is used to reduce the amount of water in the water injection chamber entering the resin chamber.
