Description

Technical Field

[0001] The utility model relates to the technical field related to ion exchange resin production, in particular to screening equipment for ion exchange resin production. Background Art

[0002] Ion exchange resin is an insoluble polymer compound with functional groups and a network structure. It is usually a spherical particle. In industrial applications, ion exchange resin has a large processing capacity, a wide decolorization range, a high decolorization capacity, can remove a variety of different ions, can be repeatedly regenerated, has a long working life, and has low operating costs. When producing ion exchange resins, in order to ensure that the ion exchange resin particles are of uniform size, they need to be screened. Therefore, a screening equipment for ion exchange resin production is needed.

[0003] The prior art has the following deficiencies: the prior art publication number CN214555043U states that “a screening and purification device for powdered ion exchange resin” “includes a purification tank, a top plate is fixedly connected to the top of the purification tank, and a feed port is connected in an inlaid manner inside the top plate, two screening nets are fixedly connected to the inner wall of the purification tank, and two discharge ports are provided on one side of the purification tank, a discharge valve is connected in an inlaid manner to the bottom of the purification tank, and support columns are welded around the bottom of the purification tank”;

[0004] In the above-mentioned equipment, when the ion exchange resin is screened, the ion exchange resin is fed into the purification tank from the feed port. However, when the ion exchange resin is fed, the size and position of the feed port are fixed, and the ion exchange resin falls on one part of the screening net. Long-term use can easily cause damage to the screening net. At the same time, the ion exchange resin is easy to roll directly to the discharge port and accumulate together, which affects the elasticity of the screening net and affects the efficient and uniform screening of the ion exchange resin.
