Description

Technical Field

[0002] Ammonium persulfate is an ammonium salt, a colorless monoclinic crystal or white crystalline powder with a melting point of 120 degrees Celsius and a relative density of 1.982. It has strong oxidizing and corrosive properties. Completely dry ammonium persulfate is not easily decomposed, but when moist, it decomposes to release oxygen and ozone. It is easily soluble in water, and its aqueous solution will also decompose at room temperature. It will also decompose when in contact with metals.

[0003] In the production process of ammonium persulfate, iron ions need to be removed from the mother liquor before it can be recycled. In the existing technology, ammonium persulfate is produced by electrolysis of cathodic and anodic solutions. Before collecting the mother liquor, it is necessary to wait for the solution to cool and crystallize and for solid-liquid separation before collecting the mother liquor for iron removal filtration. However, the existing ammonium persulfate mother liquor iron removal filtration device has low cooling efficiency, resulting in a long waiting time before collecting the mother liquor, which affects the efficiency of mother liquor recovery and subsequent utilization.

[0030] In this embodiment: after the ammonium persulfate mother liquor is cooled by the cooling tank 5, the valve of the connecting pipe 6 is opened, and the ammonium persulfate mother liquor enters the filter tank 7 through the connecting pipe 6.

[0039] In this embodiment: the rotating turntable 404 drives multiple cooling pipes 405, stirring rods 801 and stirring blades 802 to reciprocate. The reciprocating stirring rods 801 and stirring blades 802 agitate the ammonium persulfate mother liquor to be treated in the cooling tank 5. At the same time, the reciprocating cooling pipes 405 are in full contact with the agitated ammonium persulfate mother liquor to be treated in the cooling tank 5, thereby effectively increasing the cooling rate of the ammonium persulfate mother liquor, so that the solution can be cooled and crystallized quickly.

[0040] Please refer to this carefully. Figure 4 The stirring rod 801 and the stirring blade 802 are located in the middle of two adjacent cooling pipes 405, and the rotating turntable 404 is used to drive the cooling pipes 405 and the stirring blade 802 to rotate.

[0041] In this embodiment, the ammonium persulfate mother liquor to be treated in the cooling tank 5 is stirred by multiple reciprocating stirring rods 801 and stirring blades 802.

[0042] Working principle: The ammonium persulfate mother liquor requiring iron removal filtration is poured into the cooling tank 5 through inlet 2. At this time, motor 401 is powered on and started, causing the output shaft of motor 401 to drive the reciprocating screw 408 to rotate. The rotating reciprocating screw 408 drives the moving block 409 to move along the trajectory of guide rod 407. The moving block 409 drives the rack 4010 to reciprocate. Since the toothed ring 406 meshes with the toothed grooves of the rack 4010, the reciprocating rack 4010 drives the toothed ring 406 to rotate reciprocally. The rotating gear ring 406 drives the rotating tube 402 and the rotating disk 404 to reciprocate. The rotating disk 404 drives multiple cooling tubes 405, stirring rods 801 and stirring blades 802 to reciprocate. The reciprocating stirring rods 801 and stirring blades 802 agitate the ammonium persulfate mother liquor to be treated in the cooling tank 5. At the same time, the reciprocating cooling tubes 405 fully contact the agitated ammonium persulfate mother liquor to be treated in the cooling tank 5, thereby effectively increasing the cooling rate of the ammonium persulfate mother liquor and enabling the solution to cool and crystallize quickly.

[0043] After the ammonium persulfate mother liquor is cooled by the cooling tank 5, the valve of the connecting pipe 6 is opened, and the ammonium persulfate mother liquor enters the filter tank 7 through the connecting pipe 6. The iron removal components set inside the filter tank 7 remove iron from the ammonium persulfate mother liquor. Finally, the ammonium persulfate mother liquor after iron removal and filtration is discharged through the outlet 3.

[0044] It should be noted that: because a seal is provided at the rotating connection between the rotating pipe 402 and the cooling box 5, leakage can be avoided when the rotating pipe 402 is driven to rotate.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
