Description

Technical Field

[0001] The utility model relates to a heat-insulating iron remover, in particular to a heat-insulating iron remover used for filtering low-temperature easily solidified liquids. Background Art

[0002] Low-temperature, easily solidified liquids mainly refer to those liquid materials that can quickly solidify or solidify at relatively low temperatures. These liquids usually have special chemical compositions and reaction mechanisms that enable them to quickly transform into solids under low-temperature conditions. In the lithium battery industry, many low-temperature, easily solidified liquids are used as adhesives or slurries in the preparation of positive and negative electrode materials. This places extremely high demands on the purity of such liquids, but the iron removal and filtration of low-temperature, easily solidified liquids has always been a difficult problem in the industry. The main reason is that the iron removal operation is basically carried out at room temperature, and the existing iron removers are basically unable to set up a fully covered insulation structure. For low-temperature, easily solidified liquids, they are very easy to solidify in the iron remover during the iron removal process, resulting in a decrease in iron removal efficiency. Therefore, a fully insulated permanent magnetic iron remover is needed to specifically handle the iron removal and filtration of low-temperature, easily solidified liquids. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a heat-insulating permanent magnetic iron remover for use with low-temperature, easily solidifying liquids, which can keep the low-temperature, easily solidifying liquids in a stable liquid state throughout the entire iron removal and filtration process, and will not cause the iron core to be locally heated or instantly heated during the heat preservation process, resulting in unstable magnetic field strength, thereby solving the problem of easy solidification of low-temperature, easily solidifying liquids during the prior art iron removal process.

[0004] In order to solve the above technical problems, the utility model solves them through the following technical solutions: an insulating permanent magnetic iron remover used for low-temperature, easily solidified liquids, comprising a shell, a magnetic filtration group is arranged in the shell, the magnetic filtration group is connected to a feed pipe and a discharge pipe, the magnetic filtration group comprises a plurality of magnetic filters connected in sequence, the magnetic filter comprises a magnetic filter and a connecting pipe, the magnetic filter is wrapped with an insulating component, and the connecting section is connected to a heating component.

[0005] In the above technical solution, preferably, the connecting pipe comprises an upper connecting pipe and a lower connecting pipe, and the magnetic filters are connected in series head to tail through the upper connecting pipe or the lower connecting pipe.

[0006] In the above technical solution, preferably, the insulation component includes an insulation interlayer wrapped outside the magnetic filter, the top of the insulation interlayer is provided with a liquid outlet, the bottom of the insulation interlayer is provided with a liquid inlet, the liquid outlet is connected to a liquid outlet pipe, and the liquid inlet is connected to a liquid inlet pipe.

[0007] In the above technical solution, preferably, the upper connecting pipe is a straight pipe, and the upper connecting pipe is wrapped in the heating assembly.

[0008] In the above technical solution, preferably, the lower connecting tube is a U-shaped tube, and the lower connecting tube is wrapped in the heating assembly.

[0009] In the above technical solution, preferably, the magnetic filter at the same horizontal position as the upper connecting pipe is also wrapped in the heating assembly.

[0010] In the above technical solution, preferably, the thermal insulation liquid moves from bottom to top in the thermal insulation interlayer.

[0011] In the above technical solution, preferably, the shell is arranged on the mobile device.

[0012] An unavoidable problem in the heating and insulation of permanent magnetic iron removers is that the magnetic core will affect the magnetic field strength after being heated, thereby reducing the iron removal efficiency. In order to solve this problem, two different sets of heating and insulation units are used in this application, which are respectively applicable to the filtration section and the connecting section. Since the magnetic core is in the filtration section, direct heating is used in the connecting section to ensure the temperature of the pipeline, and the filtration section is insulated by liquid constant temperature insulation. This design avoids the instability of the magnetic field caused by local overheating or instantaneous overheating caused by direct heating in the filtration section. The liquid constant temperature can ensure that the entire filtration section is in the same temperature range, ensuring that the entire core is heated evenly and stably. Not only that, since the magnetic filter is continuously connected head to tail and the pipeline is relatively complicated, dividing the overall insulation structure into two sets is also convenient for design and installation.

[0013] The temperature control of the heat-insulating permanent magnetic iron remover for low-temperature easily solidified liquid in this application is stable, and a constant temperature can be maintained in the filtering section. The connecting section can be heated, and hot water or heat-insulating oil can be filled into the interlayer, etc., so as to maintain the form of the production material under the low-temperature environment, and prevent the liquid from solidifying in the filtering section due to the low temperature. By direct heating, not only can the liquid be prevented from solidifying in the connecting section due to the low temperature, but also it still has a certain temperature after entering the filtering section, so as to effectively remove iron. Whether it is the petroleum, chemical or pharmaceutical industries, this application can play an excellent role as long as there is a need to process magnetic impurities in low-temperature easily solidified liquids. Its wide range of applications makes this equipment have a high practical value.

[0014] Compared with the prior art, the present application can keep the low-temperature, easily solidified liquid in a stable liquid state throughout the entire iron removal and filtration process, and at the same time will not cause the iron core to be locally heated or instantly heated during the insulation process, resulting in unstable magnetic field strength, thereby solving the problem of easy solidification of the existing low-temperature, easily solidified liquid during the iron removal process.
