The problem of work efficiency low is caused in order to solve the iron-containing impurity that adsorbs on magnet needs to be washd from time to the deironing device that sets up before regeneration macromolecular material plastify technology at present. The utility model discloses a conveyer for getting rid of iron content impurity, its structure is as shown in attached 1-4, and this conveyer includes: the device comprises a recovery container 1, a frame 2, a motor 3, a driving roller 4, a driven roller 5, a conveyor belt 6, an electromagnet group 7, a demagnetizer 8 and a control switch 9. The device adsorbs the iron-containing impurity on the upper surface of the conveying belt 6, the iron-containing impurity does not directly contact with the electromagnet group 7, the electromagnet group 7 does not need to be repeatedly cleaned, and the working efficiency is improved.

In particular, the frame 2 is intended to carry the main part of the conveyor. The frame 2 has pulleys 21 and a platform 22.

The pulley 21 is mounted below the frame 2. A platform 22 is located at the top of the rack for providing a component mounting base.

The motor 3 is mounted on the frame 2.

The driving roller 4 is fixed at one end of the frame 2, and two ends of the rotating shaft of the driving roller are connected with the frame 2 through bearings. The rotating shaft of the driving roller 4 is connected with the power output shaft of the motor 3 through a belt.

The driven roller 5 is positioned at the other end of the frame 2, the axial rotation center of the driven roller is parallel to the axial rotation center of the driving roller 4, and the two ends of the rotating shaft of the driven roller are connected with the frame 2 through bearings.

The conveyor belt 6 is installed on circumferential surfaces of the drive roller 4 and the driven roller 5, and is circularly reciprocated as the drive roller 4 and the driven roller 5 rotate.

The electromagnet group 7 is embedded in the conveyor belt 6 and is driven along with the conveyor belt 6. The electromagnet group 7 includes a plurality of electromagnets. Each electromagnet is composed of an iron core and a coil wound on the iron core, and the length direction of the electromagnet is consistent with the width direction of the conveyor belt 6. The distance between the two ends of the electromagnet in the length direction of the machine iron core and the two sides of the corresponding conveyor belt 6 is less than 1 cm. The distance between two adjacent electromagnets is 1-5 cm. With the above configuration, when the electromagnet passes through the drive roller 4 and the driven roller 5 following the conveyor belt 6, the influence of the drive roller 4 and the driven roller 5 on the assembly can be reduced.

The demagnetizer 8 is fixed on the lower surface of the platform 22 through bolts. The platform 22 is located between the drive roller 4 and the driven roller 5, parallel to the direction of transmission of the conveyor belt 6. The structure is shown in figures 4 and 5. The demagnetizer 8 has a housing 81 and a spiral coil 83. The housing 81 has a first chamber 812 at the top and a second chamber 813 at the bottom of the housing 81. The first chamber 812 and the second chamber 813 have a plurality of sets of spiral coils 83 disposed therein. A cavity 814 is formed between the first chamber 812 and the second chamber 813. The conveyor belt 6 passes through the cavity 814.

When the conveyor belt 6 passes through the demagnetizer 8, the corresponding electromagnet group 7 is demagnetized, and ferrous impurities are removed from the surface of the conveyor belt. After leaving the demagnetizer 8, the demagnetized electromagnet group 7 regains magnetism.

And the control switch 9 is connected with the electromagnet group 7 and the demagnetizer 8 and is used for controlling the electromagnet group 7 and the demagnetizer 8 to be electrified and deenergized. Wherein, the control switch 9 is connected with the electromagnet group 7 through a collecting ring. The slip ring can be rotated, and simultaneously, the power can be transmitted from a fixed position to a rotating position.

In one embodiment, a slide 82 is also mounted within the degausser 8. A chute 82 is located below the conveyor belt 6 passing through the cavity 814 for letting ferrous impurities falling therein out of the degausser 8.

In one embodiment, the transfer device for removing iron-containing impurities further comprises a recovery vessel 1.

The recovery container 1 is installed in the demagnetizer 8 just below the bottom of the inclined slide 82. The recovery vessel 1 is slightly wider than the demagnetizer 8 to prevent iron-containing impurities from falling out of the recovery vessel 1.

In one embodiment, the recovery tank 1 is removably mounted on said frame 2.

As can be seen from the above description, the operation principle of the present conveyor is: an electromagnet group 7 is installed in the conveyor belt 6 to adsorb the iron-containing impurities. A demagnetizer 8 is arranged to demagnetize the electromagnet group 7 to make the iron-containing impurities fall off. When the material is conveyed to the conveyor belt 6, the electromagnet group 7 adsorbs the iron-containing impurities in the material to the upper surface of the conveyor belt 6. The de-ironed material enters the next stage while the ferrous impurities continue to follow the conveyor belt 6. When the conveyor belt 6 passes through the demagnetizer 8, the spiral coil 83 with the opposite magnetic field direction in the demagnetizer 8 enables part of the electromagnet entering the interior of the demagnetizer to be weakened and disappear temporarily, so that the iron-containing impurities fall freely into the slide 82 in the demagnetizer 8 and flow into the recovery container 1 through the slide 82. After leaving the demagnetizer 8, the demagnetized part of the electromagnets regain magnetism.

As can be seen from the above description, the beneficial effects of the present embodiment are: the electromagnet group 7 adsorbs iron-containing impurities in the materials on the upper surface of the conveying belt and synchronously conveys the materials and the conveying belt 6. The electromagnet group is not in direct contact with the iron-containing impurities. The electromagnet does not need to be cleaned frequently, and the working efficiency is improved. Meanwhile, the iron-containing impurities falling off in time cannot influence the adsorption force of the electromagnet group 7.
