Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In the embodiments of the present application, please refer to Figure 1 , a ferromagnetic impurity treatment structure for sodium hydroxide solution, comprising a housing 10, a liquid inlet pipe 11 is arranged at the top of the housing 10. The housing 10 and the liquid inlet pipe 11 are existing sodium hydroxide solution storage tanks and liquid inlet pipes, and the liquid is inlet in the existing manner. A storage cavity 70 communicated with the liquid inlet pipe 11 is arranged inside the housing 10. A chassis 21 is arranged at the bottom of the housing 10, a support frame 22 is fixed on the side of the chassis 21, and a circulation pump 30 and an iron remover 40 are arranged at the top of the support frame 22. The circulation pump 30 can be an existing liquid pump, and the iron remover 40 is an existing liquid iron remover, which is connected and removes iron in the existing manner. The liquid inlet end of the circulation pump 30 is connected to the housing 10 and communicated with the storage cavity 70. The liquid inlet end of the iron remover 40 is connected to the liquid outlet end of the circulation pump 30. One end of a connecting pipe 50 is connected to the liquid outlet end of the iron remover 40, and the other end of the connecting pipe 50 is fixed at the top of the housing 10. The connecting pipe 50 bypasses the iron remover 40 and the circulation pump 30 and then clings to the housing 10;

[0036] During use, the circulation pump 30 is started to suck the sodium hydroxide solution in the storage cavity 70. The solution passes through the circulation pump 30 and then through the iron remover 40. A strong magnetic field is generated by the magnet in the liquid iron remover for the ferromagnetic impurities in the sodium hydroxide. This magnetic field can attract the ferromagnetic impurities. When the liquid sodium hydroxide passes through the iron remover 40, the ferromagnetic impurities are adsorbed by the magnetic field of the magnet and fixed on the iron remover 40, thereby achieving the removal of impurities. Then, the iron-removed sodium hydroxide solution returns to the storage cavity 70 through the connecting pipe 50 to complete the circulation, so as to effectively remove the ferromagnetic impurities in the sodium hydroxide solution and enable the sodium hydroxide product to be labeled.

[0037] In a further embodiment, please refer to Figure 1, a partition structure 60 is provided inside the outer shell 10. The partition structure 60 is located above the storage chamber 70 and is connected to the connecting pipe 50. Specifically, the partition structure 60 includes a fixed shell 61 fixed inside the outer shell 10. The fixed shell 61 is located at the top of the storage chamber 70 and forms a temporary storage chamber 62 with the outer shell 10. The temporary storage chamber 62 is communicated with the connecting pipe 50. Specifically, as Figure 1 shown, a partition plate 63 is fixed inside the outer shell 10 and is located inside the temporary storage chamber 62. There is a gap between the bottom end of the partition plate 63 and the fixed shell 61. A through hole 64 is opened at the top of the side surface of the fixed shell 61. The through hole 64 is communicated with the storage chamber 70. During use, the processed sodium hydroxide solution will enter the inside of the temporary storage chamber 62 for storage, and then will enter the inside of the storage chamber 70 through the through hole 64 after reaching a certain amount, and then the above-mentioned ferromagnetic removal operation can be carried out again, so as to distinguish the solutions before and after ferromagnetic removal, and improve the efficiency and effect of ferromagnetic removal.

[0038] Furthermore, please refer to Figure 1 and 2 . An out-liquid structure 80 extending to the outside of the outer shell 10 is provided at the bottom of the fixed shell 61. Specifically, the out-liquid structure 80 includes an out-liquid hole 81 opened at the bottom of the fixed shell 61. One end of an out-liquid pipe 82 is fixed to the bottom of the fixed shell 61. The out-liquid pipe 82 is communicated with the out-liquid hole 81, and the other end extends to the outside of the outer shell 10. A sealing shell 83 covering a part of the out-liquid pipe 82 is fixed to the bottom of the fixed shell 61. An electromagnetic valve 84 is provided at the out-liquid pipe 82 and is located inside the sealing shell 83. The electromagnetic valve 84 can adopt an existing electromagnetic valve and is connected and controlled in an existing manner. When discharging is required, the electromagnetic valve 84 is opened, and the processed sodium hydroxide solution can be received after passing through the out-liquid hole 81 and the out-liquid pipe 82, and the operation is simple.

[0039] The back of the sealing shell 83 is fixedly connected to the outer shell 10. An operation hole is opened on the back of the outer shell 10, and the operation hole is communicated with the inside of the sealing shell 83 to facilitate the user to disassemble, install and operate the electromagnetic valve 84.
