The beneficial effects of the present invention are: the technique can quickly, efficiently remove the impurity of silicon carbide micro-powder, thus Improve the precision of silicon carbide micro-powder.And equipment employed in the technique also respectively has specific superiority and first carries out, specifically It is as follows:

Automatic washing stirring pool comes vehicle frame physical efficiency automatically along track automatically due to being additionally arranged travel switch and control circuit It returns and moves back and forth, high degree of automation, save trouble and labor, and washing and mixing effect are good, controllability is strong.In addition, water inlet pipe is set It counts on the side wall close to pool bottom, is conducive to disturb the micro mist material of pool bottom, raising is stirred efficiency. When pond body is cleaned and cleaned, the design of the water inlet also helps the flushing to pond body bottom surface, improves cleaning efficiency.

The filter screen of primary filtration is arranged in removal filtration sieve in feed well, can preliminarily will be larger in micro mist suspension Particulate matter filter out, after filtering, these biggish particulate matters can be taken out by opening upper cover.Therefore, the removal of impurities Screen can not only carry out primary filtration and more fine secondary filter to the micro mist suspension after washing, and due to filtering The circumference of disk, which increases, is provided with splashproof shading cloth, can be effectively prevented the micro mist suspension in filtering and splash out, reduce loss of material. Make removal filtration sieve be able to achieve mobile use in addition, castor and positioning support structure is arranged in the bottom of support body, so as to One micro mist suspension removal filtration sieve can wash stirring pool at times for multiple micro mists automatically and provide filtering and impurity removing service, mention Its high use value.

The clear matter pond of pickling mainly utilize the silicon carbide micro-powder in suspension be easy deposit buildup characteristic and pickling after it is miscellaneous Matter can swim in the characteristic on liquid level, in conjunction with dexterously designing the drain different with overflow port and multiple absolute altitudes of upper and lower water inlet Hole, when the close full pond of material, it can push liquid level water layer to flow to overflow port, and will not be to the particulate deposits of clear matter bottom of pond portion Layer generates excessive disturbance.Under the premise of avoiding particulate deposits logistics from losing, the overflows such as liquid level bubble and impurity are removed.Work as object Material is when keeping off full pond, according to actual liquid level height be it is desirable, open the stopple on the drainage hole of corresponding height, then allow again Upper water inlet is passed through clear water, allows impurity according to the practical overflow operation for perhaps needing to carry out impurity.

The clear matter pond of alkali cleaning is able to achieve alkalinity washing and the processing of clear matter to micro mist (silicon carbide), and clear matter is high-efficient.First lead to Crossing stirring power is sufficiently mixed micro mist suspension with alkalinity removal of impurities liquid, then improves reaction temperature by heat-conducting oil pipes, adds Fast micro mist suspension is reacted with alkalinity removal of impurities liquid, and finally by the mode of bubbling -cleaning, rapidly impurity suspends from micro mist It separates, and is swum on liquid level in liquid.

Classification of sedimentation processing pond is different using the time that micro powder granule staticly settles in micro mist suspension, by corresponding Sedimentation time will be layered respectively containing the micro mist sedimentation liquid of different micro powder granule sizes be discharged from top to bottom, to realize that micro mist is outstanding The classification of sedimentation of supernatant liquid is processed, in case procedure processing uses.

Drying unit is mainly used for the wet micro mist after drying drying, and drying efficiency is high, high-quality, and micro mist is avoided to fly upward damage It loses, energy conservation and environmental protection.

Rationally, structure is simple, is mainly used for focusing on the micro mist in drying tray into bucket type transfer car(buggy) for feed system design On hopper in, so that micro mist is transferred to fine screen and packing shop.Bucket type transfer car(buggy) is mainly used in the charging of micro mist fine screening machine Transhipment between system and fine screen and packing shop, cooperation suspension gear use, by the bunker lift on bucket type transfer car(buggy) to essence The feed inlet of sieve apparatus.

Micro mist fine screen packaging production equipment is mainly used for the final step of micro mist purification and classification processing, is conducive to further Improve effectiveness of classification and pack efficiency.Meanwhile setting up fine screen and packaging in different workshops separately, be conducive to the ring for improving workshop Border health.Loading platform or so can be made to be switched fast by track and castor, reduce and avoid micro mist be scattered ground the case where, because This, micro mist fine screen packaging production equipment adapts to continuously continual packed.Meanwhile the micro mist fine screen packaging production is set Standby side is additionally provided with weigher.The circumference of the weigher is provided with the bracket of semi-surrounding, and bag is sent out when preventing from weighing Life is toppled over.
