Description

Technical Field

[0001] This utility model relates to the field of ferrite magnetic powder production technology, specifically to a slurry sintering device for ferrite magnetic powder production. Background Technology

[0002] Ferrite magnetic powder refers to magnetic particles obtained by adding metal oxides to α-Fe₂O₃. α-Fe₂O₃ (commonly known as iron oxide red) is produced by calcining ferrous sulfate [FeSO₄·7H₂O], ferric oxalate [FeC₂O₄·7H₂O], or ferric nitrate [Fe(NO₃)₂·9H₂O] at relatively high temperatures (above 440 degrees Celsius). The production of ferrite magnetic powder requires a slurry sintering device.

[0003] During the sintering process, slurry sintering equipment discharges flue gas through exhaust pipes. Since the flue gas contains toxic particulate matter, direct discharge will have an impact on the environment. Therefore, a filter device is installed inside the exhaust pipe to filter the discharged flue gas. However, the filter device of existing slurry sintering equipment is usually located inside the exhaust pipe. It takes a long time to disassemble and replace it. When the filter device is disassembled and replaced, the slurry sintering equipment cannot be used, which indirectly reduces the working efficiency of the slurry sintering equipment. To address this, we propose a slurry sintering equipment for ferrite magnetic powder production. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This invention provides a slurry sintering device for ferrite magnetic powder production. When the filter layer inside the annular plate needs to be replaced, the annular plate whose filter layer needs to be replaced can be rotated away by a motor, and the new annular plate can be rotated to the exhaust pipe to continue filtering the emitted flue gas, so that the slurry sintering device can continue to carry out the sintering process. During the sintering process, the rotated annular plate can be removed and replaced. Compared with the existing disassembly and replacement methods, this invention has the advantages of quick replacement and saving time, thereby improving the working efficiency of the slurry sintering device.

[0026] Figures 1-3 The diagram shown is a structural schematic of one embodiment of a slurry sintering device for ferrite magnetic powder production according to this invention. Please refer to [link / reference]. Figures 1-3 The slurry sintering apparatus for ferrite magnetic powder production according to this embodiment includes a sintering assembly 100 and a rotary filter assembly 200.

[0027] The sintering assembly 100 includes a furnace body 110 and an exhaust pipe 120 disposed at the middle of the rear end of the furnace body 110. A support rod 111 is disposed at the lower end of the furnace body 110, and a horizontal plate 112 is fixed to the lower end of the support rod 111. A fixing plate 121 is fixed to the outer wall of the exhaust pipe 120. Preferably, in this embodiment, a bolt 113 is disposed at the upper end of the horizontal plate 112, and the bolt 113 penetrates the horizontal plate 112. The bolt 113 disposed on the horizontal plate 112 and penetrating the horizontal plate 112 can fix the horizontal plate 112 in a designated position, thereby ensuring the stable placement of the furnace body 110. A first external thread 122 is disposed on the outer wall of the exhaust pipe 120 near the end of the furnace body 110. A connecting part 114 is disposed at the middle of the rear end of the furnace body 110, and the exhaust pipe 120 is threadedly connected to the connecting part 114. The exhaust pipe 120 is connected to the first external thread 122 and the connecting part 114. The exhaust pipe 120 is installed on the furnace body 110 by a thread. Later, the operator can manually rotate the exhaust pipe 120 to remove it from the furnace body 110 for cleaning. The outer wall of the exhaust pipe 120 is provided with a sealing plate 123, and the inner side of the sealing plate 123 is provided with a sealing gasket. The sealing gasket is tightly fitted with the connecting part 114. The sealing gasket is made of rubber. The sealing plate 123 and the sealing gasket on the outer wall of the exhaust pipe 120 play a role in sealing the gap at the connection between the exhaust pipe 120 and the connecting part 114, ensuring the sealing of the connection between the exhaust pipe 120 and the furnace body 110.

[0028] The rotary filter assembly 200 includes a motor 210 mounted on a fixed plate 121, a rotating plate 220 vertically mounted at the output end of the motor 210, an annular plate 230 mounted on both sides inside the rotating plate 220, and a filter layer 240 mounted inside the annular plate 230. Threaded holes 221 are provided on both sides inside the rotating plate 220. A second external thread is provided on the lower side of the outer wall of the annular plate 230. The annular plate 230 is threadedly connected to the threaded holes 221. The lower end face of the rotating plate 220 is flush with the upper end face of the exhaust pipe 120. The annular plate 230 is located above the exhaust pipe 120. A fixing rod 231 is provided at the upper end of the annular plate 230. The filter layer 240 contains pebbles and activated carbon filler. Preferably, in this embodiment, a protective pad is provided at the lower end of the rotating plate 220 outside the threaded hole 221. The protective pad is made of rubber. The protective pad at the lower end of the rotating plate 220 serves two purposes: firstly, it protects the rotating plate 220 and prevents it from wearing against the top of the exhaust pipe 120 during rotation; secondly, it seals the gap between the exhaust pipe 120 and the rotating plate 220, preventing smoke from flowing out of the gap. The annular plate 230 has two filter layers 240 inside. The two filter layers 240 enhance the filtration of smoke and ensure the filtration effect of the smoke.

[0029] Combination Figures 1-3 This embodiment of a sintering apparatus for ferrite magnetic powder production is used as follows: During the sintering process, flue gas is discharged from the exhaust pipe 120. The filter layer 240 located in the annular plate 230 above the exhaust pipe 120 filters the flue gas. When the filter layer 240 needs to be replaced, the motor 210 is started, and the motor 210 drives the rotating plate 220 to rotate, removing the annular plate 230 whose filter layer 240 needs to be replaced. The new annular plate 230 is then rotated to the exhaust pipe 120 to continue filtering the emitted flue gas. During the sintering process, the operator manually rotates the annular plate 230 to remove the rotated annular plate 230 from the rotating plate 220, thereby replacing the internal filter layer 240. Compared with existing disassembly and replacement methods, this invention has the advantages of rapid replacement and time saving, which can improve the working efficiency of the sintering apparatus.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
