Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1 and 2, a food grade calcium carbonate deironing device, including removing iron ladle 1, it is equipped with feeder hopper 2 to remove iron ladle 1 top, and the bottom is equipped with discharging pipe 3, it transversely is equipped with agitating unit 4 to remove the upside in iron ladle 1, and agitating unit 4 below transversely is equipped with magnet stick 5, magnet stick 5 wears to locate in the plastic sleeve 6, the plastic sleeve 6 both ends are passed through connecting rod 7 and are connected with support column 8, the 6 surface cover of plastic sleeve is equipped with rather than sliding fit's sliding ring 9, seted up on the sliding ring 9 with screw rod 10 complex screw, screw rod 10 one end is passed through the bearing and is connected with support column 8, and the other end is connected with servo motor 11 output shaft, and servo motor 11 is fixed in on support column. In this embodiment, servo motor 11 controls its output shaft corotation a period of time later and reverses a period of time again, present periodic corotation and reversal, screw rod 10 also can periodic corotation and reversal like this, when screw rod 10 rotates, just can slide a section of distance right again after sliding a section of distance left along the 6 surfaces of plastic sleeve with its screw-thread fit's sliding ring 9, servo controller through adjustment servo motor 11, alright so that sliding ring 9 slides right to the 6 right end portions of plastic sleeve when sliding to the 6 left end portions of plastic sleeve left, alright so can constantly scrape to iron fillings that adsorb at the 6 surfaces of plastic sleeve in iron fillings collecting vat 14.

Preferably, agitating unit 4 includes (mixing) shaft 4.1, evenly installed a plurality of stirring vane 4.2 on the (mixing) shaft 4.1, in the bearing of iron removing jar 1 lateral wall was all erect at (mixing) shaft 4.1 both ends, wherein one end is connected with driving motor 4.3 output, and driving motor 4.3 is fixed in on the support column 8. After the driving motor 4.3 works, the stirring shaft 4.3 is driven to rotate, and then the food-grade calcium carbonate powder falling into the iron removing tank 1 is driven to stir by the stirring blade 4.2, so that the food-grade calcium carbonate powder is fully contacted with the magnet rod 5 below, and the efficiency of attracting iron filings by the magnet is improved.

Preferably, (mixing) shaft 4.1 one end still overlaps and is equipped with spur gear 4.4, spur gear 4.4 meshes with ring gear 12 of below, drum screen 13 surface is located to ring gear 12 cover, and drum screen 13 both ends all erect in removing the bearing of iron can 1 lateral wall, and inside magnet stick 5, plastic sleeve 6, sliding ring 9 and the screw rod 10 of setting up of drum screen 13, drum screen 13 are the cylindrical structure, and a plurality of sieve meshes 13.1 have been seted up on its surface. As shown in fig. 2, in order to delay the speed of the calcium carbonate powder passing through the magnetic field area of the magnet rod 5, after the cylindrical screen 13 is arranged below the stirring device 4, the calcium carbonate powder firstly passes through the screen holes 13.1 on the upper side of the cylindrical screen 13, then contacts with the plastic sleeve 6 on the surface of the magnet rod 5, and finally passes through the screen holes 13.1 on the lower side of the cylindrical screen 13 and falls into the bottom of the iron removing tank 1, so that the speed of the calcium carbonate powder passing through the magnetic field area of the magnet rod 5 can be reduced, the efficiency of attracting iron filings by the magnet is improved, and meanwhile, the screen holes 13.1 of the cylindrical screen 13 do not block the iron filings or the calcium carbonate powder; when the stirring shaft 4.3 rotates, the straight gear 4.4 is also driven to rotate, and then the ring gear 12 below the stirring shaft rotates along with the straight gear, so that the cylindrical screen 13 rotates along with the straight gear, and the blockage phenomenon caused by the stagnation of calcium carbonate powder in the cylindrical screen 13 can be further prevented in the rotating process of the cylindrical screen 13.

Preferably, scrap iron collecting grooves 14 are formed below two ends of the plastic sleeve 6. The slip ring 9 slides to the left end of the plastic sleeve 6 and then slides to the right end of the plastic sleeve 6 when sliding to the left end of the plastic sleeve 6, so that the scrap iron adsorbed on the surface of the plastic sleeve 6 can be continuously scraped into the scrap iron collecting groove 14,

preferably, the scrap iron collecting groove 14 and the iron removing tank 1 are both fixed on the supporting frame 15.

Preferably, the outer diameter of the cylindrical screen 13 is matched with the width dimension of the inner side of the iron removing tank 1. As shown in FIG. 2, the calcium carbonate powder is prevented from falling directly below without passing through the cylindrical screen 13, and the magnetic field area of the magnet bar 5 in this embodiment can be distributed over the cylindrical screen 13, so that the calcium carbonate powder passing through the cylindrical screen 13 can be ensured to be subjected to the magnetic field attraction iron removal process.

Preferably, the cylindrical screen 13 in this embodiment is made of aluminum, and the screw 10 and the slip ring 9 are made of plastic, so as to prevent the above components from being magnetized by the magnet bar 5 and affecting the iron removal process.

The working principle of the embodiment is as follows:

food-grade calcium carbonate powder entering a packaging workshop is added into the iron removing tank 1 through the feed hopper 2, after the drive motor 4.3 works, the stirring shaft 4.3 is driven to rotate, the stirring blade 4.2 is further driven to stir the food-grade calcium carbonate powder falling into the iron removing tank 1, when the stirring shaft 4.3 rotates, the straight gear 4.4 is also driven to rotate, the annular gear 12 below the straight gear rotates along with the straight gear, and the cylindrical screen 13 also rotates along with the straight gear; calcium carbonate powder firstly passes through the sieve holes 13.1 on the upper side of the cylindrical sieve 13 and then contacts with the plastic sleeve 6 on the surface of the magnet rod 5, in the process, if scrap iron is mixed in the calcium carbonate powder, the calcium carbonate powder can be adsorbed on the surface of the magnet rod 5, and the calcium carbonate powder passes through the sieve holes 13.1 on the lower side of the cylindrical sieve 13 and falls into the inner bottom of the iron removing tank 1, and then the calcium carbonate powder is discharged from the discharge pipe 3 to enter the next process; and servo motor 11 work back, its servo controller controls its output shaft corotation a period of time after the reversal a period of time again, present periodic corotation and reversal, like this screw rod 10 also can periodic corotation and reversal, when screw rod 10 rotates, just can slide a period of distance to the right after sliding a period of distance along the 6 surfaces of plastic sleeve left with its screw-thread fit's sliding ring 9, servo controller through adjustment servo motor 11, alright so that sliding ring 9 slides to the 6 right-hand member portion of plastic sleeve right when sliding to the 6 left end portions of plastic sleeve left side again, so can constantly scrape the iron fillings that adsorb on the 6 surfaces of plastic sleeve in the iron fillings collecting vat 14 of both sides, do not need the people to clear up the 6 surface adsorption iron fillings of plastic sleeve.

The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope.
