Description

Technical Field

[0001] The utility model relates to the technical field of zeolite beds, in particular to a zeolite bed used for adsorbing non-metallic mineral products such as strontium and cesium. Background Art

[0002] Zeolite bed is a device that uses zeolite as an adsorbent or catalyst. It is widely used in chemical industry, environmental protection, energy and other fields. Zeolite bed is filled with zeolite particles and uses the adsorption and catalytic properties of zeolite to treat harmful substances in gas or liquid. In the process of adsorbing strontium and cesium in some non-metallic mineral products, after selecting zeolite that can adsorb strontium and cesium, the zeolite needs to be pre-treated and cleaned to remove impurities and pollutants on its surface. After cleaning, the zeolite is dried.

[0003] Most existing zeolite beds do not have a zeolite drying structure, so it is necessary to place the zeolite in a dryer or other equipment for drying. After drying, the zeolite needs to be transferred to the zeolite bed for subsequent adsorption operations. This drying method is time-consuming, labor-intensive, and cumbersome, which is not conducive to the subsequent steps and affects the adsorption process of strontium and cesium.

[0004] To this end, a zeolite bed for adsorbing non-metallic mineral products strontium and cesium is proposed. Utility Model Content

[0026] like Figures 1 to 5 As shown, a specific embodiment of the utility model provides a zeolite bed for adsorbing non-metallic mineral products strontium and cesium, including a fixed bed column 1 in which zeolite particles can be filled and a bracket 2 arranged at the bottom end of the fixed bed column 1, a cylindrical net 3 is arranged in the fixed bed column 1, zeolite particles can be filled into the cylindrical net 3 by arranging the cylindrical net 3, and the zeolite particles are limited, and a plurality of heating wires 4 are arranged between the cylindrical net 3 and the fixed bed column 1; an extraction component for transferring zeolite particles is arranged in the cylindrical net 3, and zeolite particles in the bottom and middle of the cylindrical net 3 can be extracted and transferred to the edge close to the cylindrical net 3 by arranging the extraction component, so as to facilitate drying, and the extraction component It includes an isolation cylinder 5 arranged in the cylindrical net 3, the isolation cylinder 5 is arranged so that zeolite particles exist at the bottom end and the outer side of the isolation cylinder 5, but no zeolite particles exist inside the isolation cylinder 5, an extraction cylinder 6 is arranged in the isolation cylinder 5, and a conical bottom plate 7 is arranged in the extraction cylinder 6; it also includes a discharge assembly arranged between the bottom plate 7 and the isolation cylinder 5 for discharging zeolite particles, by arranging the discharge assembly, the zeolite particles extracted and transferred can be discharged outward from the extraction cylinder 6, so as to fall to the edge of the cylindrical net 3, the discharge assembly includes a circular support plate 8 arranged at the bottom end of the bottom plate 7, an elastic member is arranged between the circular support plate 8 and the bottom plate 7, and a cone block 9 is fixedly connected to the bottom end of the circular support plate 8.

[0027] like Figures 2 to 5As shown, specifically, a connecting block 10 is fixedly connected in the fixed bed column 1, and a heating wire 4 is fixedly installed on the connecting block 10. When the washed zeolite particles are dried, the heating wire 4 on the connecting block 10 is started, so that the heating wire 4 generates heat to dry the zeolite particles in the cylindrical net 3. A bed column cover 11 is connected to the fixed bed column 1 through a flange, and a controllable discharge pipe 12 is fixedly installed at the bottom end of the fixed bed column 1. The setting of the discharge pipe 12 facilitates the discharge of excess water in the zeolite particles. A motor 13 is fixedly installed on the top of the bed column cover 11, and a threaded rod 14 is fixedly connected to the output shaft of the motor 13, and the threaded rod 14 is threadedly connected to the round support plate 8, and the threaded rod 14 is slidably connected to the bottom plate 7. A long plate 19 is fixedly connected to the isolation cylinder 5 A guide groove 20 is provided in the long plate 19, and the round support plate 8 is slidably connected in the guide groove 20. The starting motor 13 drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 causes the round support plate 8 to move downward along the guide groove 20 in the long plate 19. A short plate 23 is fixedly connected between the round support plate 8 and the extraction cylinder 6, so that the round support plate 8 drives the top extraction cylinder 6 to move downward through the short plate 23 until the round support plate 8 moves to the bottom end of the isolation cylinder 5.

A push tube 21 is fixedly connected to the fixed bed column 1, and the threaded rod 14 passes through the inner cavity of the push tube 21. When the extraction cylinder 6 moves upward to the push tube 21, the push tube 21 applies pressure to the zeolite particles in the extraction cylinder 6, so that the zeolite particles exert pressure on the bottom plate 7 at the bottom after being subjected to pressure, so that at this time, the bottom plate 7 moves downward under the action of pressure, so that the spring 17 and the telescopic rod 18 at the bottom are forced to contract and generate a reaction force, and the bottom plate 7 moves downward so that the zeolite particles in the extraction cylinder 6 slide downward and move out of the inner cavity of the extraction cylinder 6, forming a cone The bottom plate 7 is arranged in a shape to facilitate the zeolite particles in the extraction cylinder 6 to slide down. The top of the connecting plate 16 is fixedly connected with a convex net 22. The sliding zeolite particles fall on the top of the convex net 22, and then roll and slide from the top of the convex net 22 to the surroundings, and then fall to the edge of the cylindrical net 3. The position here is convenient for receiving the heat emitted by the heating wire 4, which is convenient for drying. A slot 24 is provided in the circular support plate 8. The zeolite particles falling in the extraction cylinder 6 will fall on the circular support plate 8. At this time, the zeolite particles on the circular support plate 8 will fall downward from the slot 24 and will not remain on the circular support plate 8. An arc plate 15 and a connecting plate 16 are provided in the fixed bed column 1, and the isolation cylinder 5 is fixedly connected to the arc plate 15. The connected plate 16 passes through the cylindrical net 3 and is fixedly connected between the arc plate 15 and the fixed bed column 1.
