Detailed implementation manners

[0019] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0020] Please refer to Figures 1-5, the present utility model provides a technical solution: a resin column device with a function of adsorbing heavy metals, including a device box body 1, an installation cylinder 23 and an installation frame 8. A flow equalizing plate 4 is horizontally fixed at the upper end inside the device box body 1. An internal screw cylinder 3 is penetrated and arranged at the lower end inside the device box body 1. The upper and lower ends of the circumferential side of the installation cylinder 23 are respectively screwed with a first external thread 18 and a second external thread 20. A resin column 19 is arranged inside the installation cylinder 23. A filter screen is installed at the lower end inside the installation cylinder 23. A threaded sleeve 21 is installed at the lower end of the installation cylinder 23 by screwing, and a water outlet pipe 22 penetrates through the lower left side of the threaded sleeve 21. A clamping groove 11 is opened at the right end of the device box body 1, and an installation groove 5 is penetrated and opened at the left end of the clamping groove 11. A first metal sheet 6 is installed at the left end inside the installation groove 5. The installation frame 8 is horizontally installed in the installation groove 5. A magnet sheet 7 is arranged inside the left end of the installation frame 8. An activated carbon plate 9 is arranged inside the installation frame 8. A clamping block 10 is installed at the right end of the installation frame 8. A fixing block 13 is fixed at the upper right end of the clamping groove 11. A limiting groove 12 is opened at the connection between the fixing block 13 and the clamping block 10. A limiting block 17 is clamped at the lower end inside the limiting groove 12. Metal arc-shaped blocks are installed on the front and rear sides of the upper end of the limiting block 17. Connecting rods 16 are longitudinally fixed at the upper ends of the two metal arc-shaped blocks. Return springs 15 are sleeved on the circumferential sides of the two connecting rods 16. The upper ends of the two connecting rods 16 penetrate through the fixing block 13 and are connected with a pull handle 14. This design solves the problem that the original device relies solely on activated carbon to adsorb heavy metals in wastewater, and its effect is limited and needs to be improved.

[0021] As the first embodiment of the present utility model: A box cover is installed at the upper end of the device box body 1 through bolts, and a sewage inlet pipe penetrates through the middle of the upper end of the box cover. Legs are installed on both the left and right sides at the lower end of the device box body 1. Through the added sewage inlet pipe, it is convenient to add wastewater into the device box body 1.

[0022] A flow guiding plate 2 is installed on the inner wall of the device box body 1, and the lower end of the flow guiding plate 2 is connected to the internal screw cylinder 3. Through the added flow guiding plate 2, the wastewater filtered by the activated carbon plate 9 can be guided to the resin column 19. The resin column 19 is a chelating resin, and its mechanism is that the functional atoms on the resin react with metal ions to form a stable structure similar to a small molecule chelate. The upper end of the installation cylinder 23 is installed inside the internal screw cylinder 3 by screwing. Through the added first external thread 18 sleeved on the internal screw cylinder 3, it is convenient for the quick disassembly and assembly of the installation cylinder 23.

[0023] The magnet sheet 7 is attracted to the first metal sheet 6. Through the added magnet sheet 7 and the first metal sheet 6, the installation frame 8 is more stable when horizontally installed in the installation groove 5. The clamping block 10 is clamped in the clamping groove 11. A push-pull block is arranged at the right end of the clamping block 10. Through the added push-pull block, it is convenient to pull the clamping block 10.

[0024] As the second embodiment of the present utility model: Wastewater is added into the equipment box body 1 through the sewage inlet pipe. First, the wastewater is evenly distributed to the activated carbon plate 9 through the flow equalizing plate 4 and adsorbed and filtered by the activated carbon plate 9 (activated carbon is an adsorbent with a high specific surface area, large pore volume, controllable pore size distribution, adjustable surface chemical properties, high adsorption capacity, stable physical and chemical properties, and high mechanical strength. It can quickly and efficiently adsorb heavy metals in wastewater according to the physical and chemical properties of heavy metal ions and the different chemical environments). Then, the wastewater that has been adsorbed and filtered is guided to the resin column 19 through the diversion plate 2. The resin column 19 is a chelating resin, and its mechanism is that the functional atoms on the resin react with metal ions to form a stable structure similar to a small molecule chelate, thereby realizing the reaction filtration of heavy metals in the wastewater. Then, the wastewater will be discharged through the threaded sleeve 21 and the water outlet pipe 22. When the activated carbon plate 9 needs to be disassembled after long-term use, only need to pull up the pull handle 14, and the pull handle 14 drives the connecting rod 16 and the limiting block 17 to move upward until the limiting block 17 moves to the upper end inside the limiting groove 12 (at this time, the two return springs 15 are compressed). Then, pull the push-pull block to the right to separate the magnet sheet 7 from the first metal sheet 6, and the installation frame 8 and the activated carbon plate 9 can be removed from the clamping groove 11 of the device. When the resin column 19 needs to be replaced, rotate the installation cylinder 23 so that the upper end of the installation cylinder 23 is completely rotated out of the inner screw cylinder 3, which is quick and convenient.
