Description

A kind of silicon carbide micro-powder pickling system
Technical field
The utility model belongs to micro mist production technical field, is specifically related to a kind of silicon carbide micro-powder pickling system.
Background technology
Needing in the production of silicon carbide micro-powder will mixed various Impurity removal with which, the impurity such as to cut all must be removed as iron powder with which or iron.The technical way removing iron content class impurity is in the prior art, adopt the method for pickling, the iron in powder or slurry or other impurity and sulfuric acid reaction can be made to generate ferric sulfate and water-soluble salts solution, after being then separated with powder by solution by Precipitation.Be in the prior art by precipitation after silicon carbide micro-powder clear water again through repeatedly cleaning, until silicon carbide micro-powder is formed in neutral.Need to consume a large amount of clear water in above-mentioned cleaning process, and the sour water after cleaning also needs to process.So be necessary to improve the acid cleaning process of existing silicon carbide micro-powder.
Utility model content
The purpose of this utility model is solve the problems of the technologies described above and provide a kind of silicon carbide micro-powder pickling system.
A kind of silicon carbide micro-powder pickling system, comprise the first pickling tank, a screen plate is provided with in described first pickling tank, described screen plate is divided into two separate raw material cavity and filtering chamber the cavity of described first pickling tank, described raw material cavity connects the first water inlet pipe, described raw material cavity also connects the first acid proof pump by pipeline, described first acid proof pump connects the first drier by pipeline, described first drier connects sewage lagoon by the 3rd pipeline, described first drier connects the second pickling tank by pipeline, described second pickling tank connects the second water inlet pipe, described second pickling tank connects the second acid proof pump by pipeline, described second acid proof pump connects the second drier by pipeline, described second drier connects sewage lagoon by pipeline, described filtering chamber is connected to transition pond by pipeline, described transition pond is communicated with the 3rd acid proof pump by pipeline, described 3rd acid proof pump connects two-way valve by pipeline, described two-way valve connects raw material cavity by the first pipeline, described two-way valve connects sewage lagoon by described second pipe.
The utility model reasonable in design, through overpickling with after drying, silicon carbide micro-powder, in neutral, improve quality product, improves production efficiency, reduce labour intensity.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of a kind of silicon carbide micro-powder pickling system 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.
Refer to shown in Fig. 1, a kind of silicon carbide micro-powder pickling system, comprise the first pickling tank 2, a screen plate 17 is provided with in described first pickling tank 2, described screen plate 17 is divided into two separate raw material cavity 4 and filtering chamber 3 the cavity of described first pickling tank 2, described raw material cavity 4 connects the first water inlet pipe 5, described raw material cavity 4 also connects the first acid proof pump 6 by pipeline, described first acid proof pump 6 connects the first drier 7 by pipeline, described first drier 7 connects sewage lagoon 12 by the 3rd pipeline 18, described first drier 7 connects the second pickling tank 8 by pipeline, described second pickling tank 8 connects the second water inlet pipe 9, described second pickling tank 8 connects the second acid proof pump 10 by pipeline, described second acid proof pump 10 connects the second drier 11 by pipeline, described second drier 11 connects sewage lagoon 12 by pipeline, described filtering chamber 3 is connected to transition pond 1 by pipeline, described transition pond 1 is communicated with the 3rd acid proof pump 13 by pipeline, described 3rd acid proof pump 13 connects two-way valve 14 by pipeline, described two-way valve 14 connects raw material cavity 4 by the first pipeline 15, described two-way valve 14 connects sewage lagoon 12 by described second pipe 16.
Described two-way valve 14 is Electric automatic control valve.
The operating process of the utility model pickling silicon carbide micro-powder is, silicon carbide micro-powder and pickle solution are joined in the first pickling tank 2, by the first acid proof pump 6, its mixed solution is extracted into drying in the first drier 7 after stirring, the waste liquid that first drier 7 is discharged is displaced in sewage lagoon 12 by the 3rd pipeline 18, then the silicon carbide micro-powder after being dried by the first drier 7 adds in the second pickling tank 8, add clear water by the second water inlet pipe 9 and stir in the second pickling tank 8 simultaneously, with the second acid proof pump 10 mixed solution in second pickling tank 8 is extracted in the second drier 11 again and dries, the waste liquid that second drier 11 is discharged is delivered in sewage lagoon 12 by row of conduits, acid content after can making pickling and washing by the drying of the second drier 11 in silicon carbide micro-powder reduces greatly, thus the consumption of rinse water can be saved, also save the time of washing simultaneously.
Preferably, for improving silicon carbide micro-powder quality, the micro mist after the second drier 11 can being dried, can pass through the further pickling of the utility model silicon carbide micro-powder pickling system and drying.
The utility model reasonable in design, through overpickling with after drying, silicon carbide micro-powder, in neutral, improve quality product, improves production efficiency, reduce labour intensity.
Above embodiment is only most preferred embodiment of the present utility model, not in order to limit the utility model, all make within principle of the present utility model any amendment, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
