[0002] With the rapid development of industry and the increasing frequency of human activities, a large amount of sewage containing heavy metal ions is discharged into the environment. For example, mining, metallurgy, electroplating, chemical industry and other industries will produce a large amount of wastewater containing heavy metal ions in the production process. For example, electroplating wastewater often contains copper, nickel, chromium and other heavy metal ions; metallurgical wastewater may contain lead, zinc, cadmium and other heavy metal ions.

[0003] The active filter material will gradually saturate after a certain period of time, and the adsorption capacity of heavy metal ions will decrease. For example, common adsorption materials such as activated carbon, as the amount of adsorbed heavy metal ions increases, the pores will be gradually occupied, resulting in reduced adsorption efficiency. When it reaches the saturation state, if the filter medium is not replaced or regenerated in time, it will not be able to effectively remove heavy metal ions from the sewage. When the activated carbon filter plate stays in the filter equipment for a long time, it is difficult to remove the activated carbon filter plate from the filter equipment, increasing the difficulty of replacing the activated carbon filter plate for the workers, and also affecting the efficiency of sewage treatment. Therefore, a sewage heavy metal ion remover is proposed. SUMMARY

[0006] As a further improvement of the technical solution, the casing and the fixed frame are provided with extrusion assemblies on both sides, the extrusion assemblies include L-shaped bars, the L-shaped bars are fixedly installed on one side of the casing near the fixed frame, the fixed frame is threadedly connected with a threaded rod, one end of the threaded rod is rotatably connected with a first extrusion block, and a second extrusion block is fixedly installed on one side of the fixed frame and near the L-shaped bar.

[0007] As a further improvement of the technical solution, one end of the extrusion spring is fixedly connected to one side of the limiting groove, and one end of the extrusion spring is fixedly connected to the inner wall of the shell. The plurality of extrusion springs drive the extrusion square tube to slide in the shell.

[0008] As a further improvement of the technical solution, when the fixed frame is removed, the plurality of extrusion springs push the plurality of activated carbon filter plates out of the shell through the extrusion square tube.

[0009] As a further improvement of the technical solution, when the fixed frame is inserted into the shell, the first extrusion block is extruded against the second extrusion block by rotating the threaded rod, so that the fixed frame is fixed on the shell.
