Another technical scheme of the present invention is：This production equipment includes automatically washing stirring pool, removal of impurities is filtered sieve, pickling
Clear matter pond, alkali cleaning clear matter pond, classification of sedimentation processing pond, drying unit, feed system and micropowder fine screen packaging production equipment.Each
Elaborated above the detail of equipment, just repeated no more here.
The beneficial effects of the present invention is：This technique can quickly, efficiently remove the impurity of silicon carbide micro-powder, thus
Improve the precision of silicon carbide micro-powder.And equipment also each has specific superiority and first carries out, specifically employed in this technique
As follows：
Automatically washing stirring pool, due to being additionally arranged travel switch and control circuit, makes vehicle frame physical ability automatically past along track automatic back-and-forth
Multiple motion, high degree of automation, save trouble and labor, and washing and mixing effect are good, and controllability is strong.In addition, water inlet pipe design is existed
On the side wall of cell body bottom, be conducive to the micropowder material of cell body bottom is carried out disturbance, improve stirring mixing efficiency.In pond
When body cleaning cleaning, the design of this water inlet also helps the flushing to cell body bottom surface, improves cleaning efficiency.
Removal of impurities is filtered sieve arranges the preliminary drainage screen filtering in feed well, can preliminarily will be larger in micropowder suspension
Particulate matter filter out, filter after terminating, in unlatching, these larger particulate matters can be taken out by lid.Therefore, this remove impurity
Screen tentatively can not only be filtered and more fine secondary filter to the micropowder suspension after washing, and due to filtering
All portions increasing of disk is provided with splashproof shading cloth, can be effectively prevented the micropowder suspension when filtering and spill, reduce loss of material.
In addition, making removal of impurities is filtered sieve enable mobile use in the bottom of stake body setting castor and positioning support structure, so that
One micropowder suspension removal of impurities is filtered sieve can wash stirring pool for multiple micropowders at times automatically provides filtering and impurity removing service, carries
Its use value high.
Pickling clear matter pond mainly utilizes the characteristic of the easy deposit buildup of silicon carbide micro-powder in suspension, and miscellaneous after pickling
Matter can swim in the characteristic on liquid level, the discharge opeing different with overfall and multiple absolute altitude in conjunction with dexterously designing upper and lower water inlet
Hole, when material is close to full pond, it can promote liquid level water layer to flow to overfall, again will not be to the particulate deposits in clear matter at the bottom of pond portion
Layer produces excessive disturbance.On the premise of avoiding particulate deposits logistics to lose, the overflows such as liquid level bubble and impurity are removed.Work as thing
When full pond kept off by material, according to actual liquid level height is needs, opens the stopple on the outage of corresponding height, then allows again
Upper water inlet is passed through clear water, makes impurity perhaps can need to carry out the overflow operation of impurity according to reality.
Alkali cleaning clear matter pond enables to micropowder（Carborundum）Alkalescence washing and the processing of clear matter, and clear matter efficiency high.First lead to
Crossing stirring power makes micropowder suspension be sufficiently mixed with alkaline remove impurity liquid, then improves reaction temperature by heat-conducting oil pipes, plus
Impurity, finally by the mode of bubbling -cleaning, is rapidly suspended by fast micropowder suspension and the reaction of alkaline remove impurity liquid from micropowder
Separate in liquid, and swim on liquid level.
The time that classification of sedimentation processing pond is staticly settled in micropowder suspension using micro powder granule is different, through corresponding
Sedimentation time, respectively the micropowder sedimentation liquid layering containing different micro powder granule sizes is discharged from top to bottom, thus realize micropowder hanging
The classification of sedimentation processing of supernatant liquid, in case one procedure processing uses.
Drying unit is mainly used in drying the wet micropowder after drying, and its drying efficiency is high, quality is good, it is to avoid micropowder flies upward damage
Lose, energy-conserving and environment-protective.
Feed system is reasonable in design, and structure is simple, and it is mainly used in for the micropowder in drying tray focusing on bucket type transfer car(buggy)
On hopper in so that micropowder is transferred to fine screen and packing shop.Bucket type transfer car(buggy) is mainly used in the charging of micropowder fine screening machine
Transhipment between system and fine screen and packing shop, cooperation suspension gear uses, by the bunker lift on bucket type transfer car(buggy) to essence
The charging aperture of sieve apparatus.
Micropowder fine screen is packed production equipment and is mainly used in micropowder purification and the final step of classification processing, is conducive to further
Improve effectiveness of classification and pack efficiency.Meanwhile, fine screen and packaging are set up separately in different workshops, be conducive to improving the ring in workshop
Border health.Can make to be switched fast about loading platform by track and castor, reduce and avoid micropowder to be scattered the situation on ground, because
This, micropowder fine screen packaging production equipment adapts to continuously continual pack.Meanwhile, described micropowder fine screen packaging production sets
Standby side is additionally provided with weigher.All portions of described weigher are provided with the support of semi-surrounding, are sent out with bag when preventing from weighing
Life is toppled over.
