Heater comprises heater 13, the hot recycle pump 21 that is arranged on frame and the thermal conductive water pipe 28 who is communicated with heater 13, hot recycle pump 21 and feed bin interlayer 34.
Electric control gear comprises electric cabinet 16 and the frequency converter 20 that is arranged on frame.
In the present embodiment, feed bin lid 4 is provided with vent valve 7, shooting hole 5 and two through holes 6.Shooting is equipped with a camera in the hole, and camera is connected with display screen 8.Display screen 8 can present image by the signal that camera transmits, and facilitates the staff to observe the interior working condition of feed bin 3.In two through holes 6, a through hole 6 is charging doors, and another one through hole 6 is observation panels, is provided with illuminating lamp on observation panel.
Before machine work, whether the rotation direction that needs to check main motor 11 and vavuum pump 14 meets the requirements.Then whether check in heater topped up with water to guarantee the interior topped up with water of heater 13, open hot recycle pump 21, open the vent valve 7 on feed bin lid 4, so that Bas Discharged, guarantee that all circulating lines fill with water.Operating temperature as required, the optimum temperature of heater heating are 45 degree.Next guarantee again topped up with water in condensation unit 15, then set according to actual needs best cryogenic temperature 4 degree, when if operating ambient temperature is spent lower than 0 or really need to add 10 liters of absolute alcohols below Temperature Setting 0 degree in condensation unit 15, or use anti-icing fluid with anti-freeze.
After heater and condensate recovery system move to design temperature, begin normal operation.The staff first pours rare earth permanent magnet powder in feed bin 3 into from the charging door on feed bin lid 4, then pours deployed binding agent into, then charging door is sealed.The staff controls main motor 11, the speed that main motor 11 speed settings per minute 12 turn by electric cabinet 16 and frequency converter 20.Main motor 11 drives power transmission shaft 29 and rotates, and power transmission shaft 29 drives rabbling mechanism 31 and rotates, and begins mixed powder work.Mixed powder is after 10 minutes, and the staff improves main motor 11 rotating speeds again and turns to per minute 20, opens 3 heating of heater feed hopper, and simultaneously, the open cold condensation reclaiming system extracts the acetone in feed bin 3.In vavuum pump 14 work, can be in vacuum environment of the interior formation of feed bin 3.In vacuum environment, rare earth permanent magnet powder just can be not oxidized in the process that stirs, and saved the expense of traditional nitrogen protection, saved production cost.
When opening heater, hot recycle pump 21 work, the hot water of heater 13 heating under the work of hot recycle pump 21 in heater 13, heating pipe 28, complete circulation of the interior formation of feed bin interlayer 34, like this with regard to the heating raw materials in feed hopper 3.During the open cold condensation reclaiming system, need first open vacuum valve 25, then open vavuum pump 14.Acetone under the effect of vavuum pump 14 through piping 19 to condensation unit 15, cooling formation liquid, then flow in recycling cans 24 through piping 19.The staff observes the open amount of vacuum valve 25 by vacuum meter 27.Usually, the open amount of vacuum valve 25 must not be greater than 1/2, otherwise acetone can not get fully coolingly just being got rid of by vavuum pump 14, contaminated environment.Reclaim to store the recycling can 24 of acetone, opened liquid valve 23 every 15 minutes, acetone is standby from collecting after liquid valve 23 flows out.Like this, can not only save production cost, also can avoid the acetone gas contaminated air, harm staff's health of human body is realized environmental protection, working environment is pollution-free.
After 1.5 hours, the rare earth permanent magnet powder in feed bin 3 is dry, caking slowly, at this moment, needs to improve main motor 11 rotating speeds.The staff transfers to main motor 11 rotating speeds between 50-60 turns by electric cabinet 16 and frequency converter 20, the rare earth permanent magnet powder of broken caking.After about 15 minutes, the rare earth permanent magnet powder blocking loosening becomes graininess.This time, the staff closes vavuum pump 14 and hot recycle pump 21 successively, open the vent valve 7 on feed bin 3, then close main motor 11, open discharging opening 30 on feed bin 3 bottom surfaces by discharging switch 32 at last, by discharging opening 30 blowings, in blowing, open main motor 11, and be 10 rev/mins with its speed setting, the beginning automatic discharging, blowing is closed main motor 11 after finishing.
In the whole course of work, the staff can observe by the observation panel that feed bin covers on 4, also can be by the concrete condition in image viewing material 3 storehouses that present on display screen 8.
When needing cleaning feed bin 3, need first the fastening bolt 33 between feed bin 3 and feed bin lid 4 to be opened, the staff controls hydraulic oil pump 18 work by electric cabinet 16.Under the effect of hydraulic oil pump 18, lifting hydraulic cylinder 17 drives lifting platform 9 and rises along slideway 12.Because lifting platform 9 and feed bin lid 4 is to link together by connector 2, so along with the rise of lifting platform 9, main motor 11, power transmission shaft 29, rabbling mechanism 31, feed bin lid 4 rise together, until nethermost rabbling mechanism 31 is higher than feed bin 3 upper ends.Then stretch out work at the piston rod of controlling horizontal hydraulic cylinder 26, promote sliding panel 1 and outwards move, until adapt to the needs of cleaning work.After cleaning out, first pass through horizontal hydraulic cylinder 26 with feed bin 3 returns, then by lifting hydraulic cylinder 17, lifting platform 9 is put down.By the time feed bin lid 4 coordinates completely with feed bin 3, and all fastening bolts 33 is fastening, and feed bin covers 4 and just seals with feed bin 3 like this, and cleaning work is completed.
