Utility model content
The purpose of this utility model is solve the problems of the technologies described above and provide a kind of Novel silicon carbide micro-powder pickling system.
A kind of Novel silicon carbide micro-powder pickling system, comprise pickling tank, described pickling tank is divided into the first pickling tank, second pickling tank and the 3rd pickling tank, described first pickling tank, second pickling tank and the 3rd pickling tank are separately installed with the first drier, second drier and the 3rd drier, described 3rd drier is provided with discharge port, described first drier, second drier is connected acid proof pump with the 3rd drier respectively by pipe connecting, described acid proof pump connecting pipeline, described pipeline extend in pickling tank, described first pickling tank, second pickling tank and the 3rd pickling tank are respectively equipped with agitator motor, described agitator motor connects stir shaft, described stir shaft installs agitating vane, described first pickling tank, second pickling tank and the 3rd pickling tank are respectively equipped with water inlet pipe, described first drier connects the second pickling tank by the first pipeline, described second drier connects the 3rd pickling tank by second pipe, described first drier connects sewage lagoon by the 3rd pipeline, described second drier connects sewage lagoon by the 4th pipeline, described 3rd drier connects sewage lagoon by the 5th pipeline.
Described agitator motor is servomotor.
Specific works process: the slurry after alkali cleaning is got in the first pickling tank, by acid proof pump its mixed solution is extracted in the first drier after stirring and dries, the waste liquid that first drier is discharged is delivered in sewage lagoon by the 3rd row of conduits, then the silicon carbide micro-powder after being dried by the first drier adds in the second pickling tank, in the second pickling tank, add clear water by water inlet pipe and stir simultaneously, with acid proof pump the mixed solution in the second pickling tank is extracted in the second drier again and dries, the waste liquid that second drier is discharged is delivered in sewage lagoon by the 4th row of conduits, add in the 3rd pickling tank by the silicon carbide micro-powder after the second drier dries, in the 3rd pickling tank, add clear water by water inlet pipe and stir simultaneously, with acid proof pump the mixed solution in the 3rd pickling tank is extracted in the 3rd drier again and dries, the waste liquid that 3rd drier is discharged is delivered in sewage lagoon by the 5th row of conduits, silicon carbide micro-powder after 3rd drier dries is collected by discharge port, the utility model improves silicon carbide micro-powder pickling efficiency, the silicon carbide micro-powder purity obtained is higher.
Accompanying drawing explanation
Figure 1 shows that a kind of Novel silicon carbide micro-powder pickling system schematic diagram that the utility model embodiment provides.
Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
