Size barrel 2 is arranged in frame 1, and the bottom of size barrel 2 is that arcuate structure and radius of curvature are the half of left and right two sidewall spacing.Offer plasma discharge mouth 2.2 in the position that has just entered slurry near bar magnet, just left the position of slurry near bar magnet and offered stock inlet 2.1.And the height of stock inlet 2.1 is greater than the height of plasma discharge mouth 2.2.Ensure that thus slurry can normally discharge.
As shown in Figure 3,4, inner bag 3 is set in size barrel 2, inner bag 3 is cylindrical structural, and platform 3.2 is offered on inner bag 3 tops, and places and connect iron pan 6 on this platform, and inner bag 3 is concentric with the bottom arcuate structure of size barrel 2.Inner bag 3 central authorities offer the hole 3.1 of running through inner bag 3 front/rear ends.The inwall of the front end face of inner bag 3 and size barrel 2 is fixed.
As shown in Figure 5,6, bar magnet group 4 comprises central shaft 4.1, bar magnet 4.2 and bar magnet dish 4.3, and the edge of bar magnet dish 4.3 is outwardly, forms annular boss 4.4.Bar magnet 4.2 is uniformly distributed into two circles on annular boss 4.4.One end of central shaft 4.1 is fixed on the central authorities of bar magnet dish 4.3.The first half section movable set of central shaft 4.1 in the first fixed mount 1.1, second half section movable set in hole 3.1, bar magnet group 4 can be rotated with central shaft 4.1.The top of size barrel is lower than bar magnet group's top, makes most of bar magnet in size barrel, be able to contact with slurry and remaining fraction bar magnet exposes slurry liquid level and is able to deferrization.The card of bar magnet dish 4.3 is perpendicular to the ground.Bar magnet group 4 rotation is by driven by motor, and adopts belt mechanism to connect transferring power.This is routine techniques means, does not repeat.
As Figure 11 to 14, the iron filings that adopt scraper plate and wiper arm 9 to erase on bar magnet.On scraper plate, offer 6 circular holes, arrangement mode and the bar magnet of circular hole 8.2 adapt, and circular hole 8.2 positions arrange rubber sleeve 8.1, utilize its elasticity iron filings of erasing.Every 6 bar magnets are one group, and every group of bar magnet wrapped up in a scraper plate of cover by circular hole, and the scraper plate that on two adjacent groups bar magnet, cover is wrapped up in is not connected mutually.The side of working up and down at the bar magnet in extreme higher position all respectively arranges a wiper arm 9, and one end connecting power device of wiper arm 9, the other end connect left pusher dog 9.1 and right pusher dog 9.2, between left pusher dog 9.1 and right pusher dog 9.2, leave space 9.3.Bar magnet group rotates while driving scraper plate to rotate, and the edge of each scraper plate all can be passed freely in the space 9.3 between left pusher dog 9.1 and right pusher dog 9.2; Left pusher dog 9.1 and right pusher dog 9.2 are all isolated with bar magnet.
As shown in figure 15, front at the part bar magnet that exposes slurry arranges an eraser 10, the inside of eraser offers the water cavity 10.2 that can make water enter, on the rear end face of eraser, offer and the water hole 10.3 of this water cavity UNICOM, and position beyond the rear end face water hole of eraser arranges rubber eraser skin 10.1.The rear end face of eraser is that face towards bar magnet rear end, and therefore this rear end face is parallel with the plate face of scraper plate, and can move to bar magnet at scraper plate and contact with scraper plate foremost time.This eraser drives linear reciprocation to move by motion control device.It should be noted that: eraser can be not moving linearly intermittently.Drive the motion control device of eraser can adopt crank rod movement mechanism or hydraulic cylinder control etc., this repeats no more for routine techniques.In the time that scraper plate moves to bar magnet front end along bar magnet, the rubber eraser skin on eraser contacts and moves back and forth with the front end face of scraper plate, and water hole sprays current simultaneously iron filings are washed out.
As shown in Figure 8,9, 10, in order to make slurry that deposited phenomenon can not occur, be set with annular agitator 7 in bar magnet group 4 outside.The agitator 7 of annular comprises cylindrical shell 7.1 and stirring shaft 7.2, and one end of stirring shaft 7.2 is connected with the central position of cylindrical shell 7.1 ends, and the other end passes also movable set the second fixed mount 1.2 from the rear wall of size barrel 2.On the wall of cylindrical shell 7.1, offer evenly distributed slotted hole groove, and at each slotted hole groove place, a plectrum 7.3 is set, the rotation direction that plectrum 7.3 is connected with agitator 7, agitator is pointed in upper end.Because the rotating ratio bar magnet group's of agitator rotating speed is a lot of soon, therefore, when agitator 7 rotates, plectrum 7.3 can stir slurry and roll and it is fully mixed and do not precipitate, and slurry is stirred to bar magnet direction simultaneously, and slurry is fully contacted with bar magnet.The rotation of agitator 7 is also dragged by motor, and adopts equally belt mechanism to connect transferring power.This is conventional means, does not repeat.
In this embodiment, the rotation of bar magnet group 4 and agitator 7 is to drive respectively by two motors, and arbitrarily adjusting rotary speed is to meet different deironing requirements.
Operation principle of the present invention and the course of work are as follows:
After starting device, inject pending slurry from stock inlet 2.1, bar magnet group 4 rotates under motor drives.Meanwhile, agitator 7 also rotates thereupon.The rotation of bar magnet is step-by-step movement, turns an angle just and to suspend, and then turn an angle and suspend, goes round and begins again.
Bar magnet in slurry is used for inhaling iron, whenever bar magnet is during from slurry transfer source in deferrization position, scraper plate on one group of bar magnet in this position enters in the space 9.3 between left pusher dog 9.1 and right pusher dog 9.2 just, and now bar magnet group stops operating, and wiper arm 9 moves under the driving of power set.Now, left pusher dog 9.1 first contacts scraper plate and promotes scraper plate and moves to the front end of bar magnet, and in moving process, scraper plate is erased iron filings.In the time that scraper plate moves to bar magnet front end along bar magnet, the rubber eraser skin on eraser contacts and moves back and forth with the front end face of scraper plate, and water hole sprays current simultaneously iron filings are washed out.By traverse motion repeatedly, the iron filings on scraper plate are wiped, after wiping, wiper arm 9 oppositely moves, now the moving scraper plate of right pusher dog 9.2 promotion moves to bar magnet rear end, after resetting, bar magnet group is rotated further, and stops until the scraper plate of next group bar magnet enters in the space 9.3 between left pusher dog 9.1 and right pusher dog 9.2.
When bar magnet rotates, slurry during just entering slurry again with the bar magnet that has taken off iron before plasma discharge mouth is discharged and the slurry that is about to discharge is carried out to smart deironing.Owing to having taken off, the bar magnet iron-attracting performance of iron is the strongest, and therefore this part slurry iron-holder in the time entering plasma discharge mouth is few, has higher quality.And slurry is when stock inlet enters size barrel, just a part of bar magnet finishing with suction iron and produce slurry contacts and carries out thick deironing, the bar magnet of thick deironing itself has carried a large amount of iron filings, and therefore iron-attracting performance is the most weak, and therefore slurry also will continue to inhale for a long time iron by turning into most of bar magnet of slurry.
Embodiment bis-
Compared with embodiment mono-, the present embodiment changes in deferrization mode.As shown in Figure 7, in order more quickly the iron filings of absorption on bar magnet 4.2 being removed, can not swipe with bar magnet 4.2 again, also can to adopt High-Pressure Water to rinse.Rotary water jet device 5 is arranged in frame 1, and rotary water jet device 5 comprises shower nozzle 5.1, and shower nozzle can rotate, and rotary water jet device is positioned at a side of pusher dog.Therefore when bar magnet group rotates while making scraper plate 8 on it just enter in the space between left pusher dog 9.1 and right pusher dog 9.2, wiper arm 9 drives scraper plate 8 to move shower nozzle simultaneously to bar magnet front end and rotates and spray water, the water of ejection forms spiral hydrosphere and rinses bar magnet, and the iron filings on iron filings and the scraper plate 8 of this bar magnet absorption are washed out.For deferrization effect, multiple rotary water jet devices 5 can be set, but arrangement mode all adapts with the arrangement mode of bar magnet, increase to greatest extent the area of bar magnet 4.2 outer walls that are flushed to by water, ensure thus deferrization effect.Rotary water jet device 5 is prior art, and its structure and principle all do not repeat.
Another effect of rotary water jet device is to wash out the slurry attaching on scraper plate, reason is that scraper plate all can attach some slurries on rubber sleeve and bar magnet out time from slurry, and scraper plate is in the time of mobile deferrization, these slurries can serve as the contact medium between rubber sleeve and bar magnet, and due to the granule that contains some in slurry and there is certain degree of hardness, therefore occur will certainly cause the scraping of these particles to bar magnet while friction at rubber sleeve and bar magnet, thus damage bar magnet.Therefore rotary water jet device can wash away slurry before deferrization, reduces bar magnet scraping phenomenon, has played the effect of protection bar magnet.
What deserves to be explained is, in the time that scraper plate 8 enters in the space of left pusher dog 9.1 and right pusher dog 9.2 just the position of bar magnet be the extreme higher position in bar magnet motion process be also deferrization position, in the time of this position, bar magnet group suspends rotation, and scraper plate 8, wiper arm 9 and rotary water jet device are all worked simultaneously and carried out deferrization.
Discharge in time in order to make to be rushed by water the iron filings that fall, water can also be reclaimed simultaneously, in the rear end of inner bag 3, baffle plate 3.3 is set, and arrange one in inner bag 3 platform 3.2 positions and connect iron pan 6, this connects iron pan and is also positioned at the below of pusher dog, the rear end that connects iron pan 6 is connected with baffle plate 3.3, and baffle plate 3.3 can stop fallen iron filings to enter in slurry, makes iron filings discharge in the lump and reclaim together with water.
The table top of annular boss 4.4 extends 5cm to central authorities and forms retaining ring 4.5.The inner ring of retaining ring 4.5 is pointed tooth structure, is compared to level and smooth edge structure, and pointed tooth structure is more conducive to falling of current.This is that when inner ring does not have pointed tooth structure, the Hui Yan edge, edge that water flows to inner ring flows down instead of directly falls because water has viscosity and has surface tension; In the time that edge part is pointed tooth structure, water flows down along the edge of pointed tooth structure equally.Pointed tooth structure has played under guiding current and has avoided to runs down both sides.
Because wiper arm 9 belows connect iron pan, connecing iron pan 6 rears has baffle plate 3.3 to intercept, and fallen water and iron filings can only be advanced towards the front that connects iron pan 6, and unified recovery.Can continue to pass in rotary water jet device 5 through water after filtering and recycle.In this process, the existing bar magnet of inhaling iron in slurry, also there is the bar magnet that leaves slurry and carry out deferrization, and slurry inlet and outlet is all continuous, therefore greatly improved de-ironing efficiency, bar magnet 4.2 used is neodymium iron boron bar magnet simultaneously, and magnetic force is strong, can reach good de-ferrous effect, be suitable for extensive deironing operation.
In the present invention, deferrization device both can adopt scraper plate, wiper arm 9 to smear iron simultaneously and rotary water jet device rushes iron, also can adopt respectively one wherein to carry out deferrization, and scraper plate is smeared iron or rotary water jet device rushes iron.Above-mentioned two kinds of deferrization modes all can be carried out separately, complete deferrization operation.
The above, be only preferred embodiment of the present invention, is not the restriction of the present invention being made to other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
