Description

Technical Field

[0001] The invention relates to the technical field of slurry demagnetization equipment, in particular to a conductive slurry demagnetization device. Background Art

[0002] Conductive paste is a paste or liquid material containing conductive particles (such as silver, copper, nickel, gold or their alloys) mixed with a resin matrix (such as epoxy resin), a solvent and possible additives (such as glass powder, etc.). This material has good conductivity and can be solidified into a conductive film or three-dimensional structure under certain conditions; in the processing of conductive paste, a demagnetization mechanism is required to remove the magnetic metal impurities inside it. It is a device used to remove magnetic impurities in conductive paste, and is mainly used in fine chemical fields such as lithium-ion battery positive and negative electrode materials, electronic paste, etc.

[0003] During use, the existing conductive slurry demagnetization mechanism mostly uses a demagnetization rod to adsorb the magnetic metal substances in the slurry. The demagnetization is carried out by installing multiple magnetic rods in a tank at the same time. The metal substances in the slurry are removed by the adsorption force generated by the magnetic field of the magnetic rod on the magnetic metal substances. However, during the process of injecting the slurry, the flow rate is relatively fast, resulting in insufficient contact time with the magnetic rod, which will cause the demagnetization effect of the slurry to deteriorate.

[0006] As a further solution of the present invention, the fixing plate is tilted, and the tilt angle is 15-35°.

[0013] As a further solution of the present invention, a roller is provided on the lower side of the end of the fixed plate.

[0014] As a further solution of the present invention, the rotating roller is provided with blades arranged at equal intervals.

[0015] Since the present invention adopts the above technical scheme, the advantages and positive effects of the present invention are: the conductive slurry enters the fixed plate in the primary demagnetization part from the feed inlet, and part of the magnetic metal impurities can be retained on the fixed plate through the attraction of the first electromagnet; after the conductive slurry enters the secondary demagnetization part after one adsorption, the second electromagnet on the lower side of the fixed disk can adsorb the magnetic metal impurities in the conductive slurry, and the magnetic metal impurities in the conductive slurry can be completely removed through the primary demagnetization and the secondary demagnetization; the first cylinder on the bracket drives the sealing cover to lift, and then drives the fixed disk and the second electromagnet to lift, and after power failure, the magnetic metal impurities on the second electromagnet can be collected, and the active gear on the motor drives the passive gear and the rotating shaft to rotate, and the rotation of the fixed disk and the second electromagnet can quickly adsorb the magnetic metal impurities, saving adsorption time, and is convenient and efficient to use, with good practicality.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6 As shown, a conductive slurry demagnetization device of the present invention is provided with a feed port 1, a primary demagnetization part 2, and a secondary demagnetization part 4 in sequence according to the production direction, wherein the primary demagnetization part 2 comprises a fixed plate, and a first electromagnet 3 is fixedly connected to the lower side of the fixed plate; The secondary demagnetization part 4 includes a box body, a bracket 5 is connected to the box body, a first cylinder 6 on the bracket 5 is connected to a sealing cover 7, a motor 8 is provided on the sealing cover 7, a driving gear 9 on the motor 8 is connected to a passive gear 10 at the top of the rotating shaft, a demagnetization mechanism 12 is connected to the lower side of the rotating shaft, the demagnetization mechanism 12 includes a fixed disk 15, and a plurality of second electromagnets 18 are connected to the lower side of the fixed disk 15. The conductive slurry enters the fixed plate in the primary demagnetization part 2 from the feed inlet 1, and some magnetic metal impurities can be retained on the fixed plate through the attraction of the first electromagnet 3; after the conductive slurry is adsorbed once, the second electromagnet 18 on the lower side of the fixed disk 15 can adsorb the magnetic metal impurities in the conductive slurry, and the magnetic metal impurities in the conductive slurry can be completely removed through the primary and secondary demagnetization; the first cylinder 6 on the bracket 5 drives the sealing cover 7 to rise, and then drives the fixed disk 15 and the second electromagnet 18 to rise, and after power failure, the magnetic metal impurities on the second electromagnet 18 can be collected, and the driving gear 9 on the motor 8 drives the driven gear 10 and the rotating shaft to rotate, and the rotation of the fixed disk 15 and the second electromagnet 18 can quickly adsorb the magnetic metal impurities, saving the adsorption time, and the use is convenient and efficient, and the practicability is good.

[0025] In the present invention, the fixing plate is tilted at an angle of 15-35°. A fixing plate with a smaller tilt angle can reduce the flow rate of the conductive slurry on the fixing plate, so that the first electromagnet 3 can quickly absorb magnetic metal impurities.

[0026] In the present invention, the fixing plate is provided with a plurality of grooves 13, and the plurality of grooves 13 are arranged at equal intervals. The plurality of grooves 13 arranged at equal intervals can absorb a large amount of magnetic metal impurities.

The material of the movable plate 17 is rubber or silicone. After the production is completed, although some magnetic metal impurities fall after the power is turned off, some magnetic metal impurities and the conductive slurry are still adhered to the second electromagnet 18. The movable plate 17 can be driven downward by the second cylinder 16 to scrape off the mixed material on the second electromagnet 18.

[0029] In the present invention, a plurality of the second electromagnets 18 are evenly distributed on the lower side of the fixed plate 15. The plurality of second electromagnets 18 evenly distributed on the lower side of the fixed plate 15 are more stable.

[0030] In the present invention, a roller 11 is provided at the lower side of the end of the fixed plate. When the conductive slurry flows down from the fixed plate, it will be dispersed after impacting the roller 11, which is more conducive to secondary demagnetization.
