A filtering method of a neodymium iron boron waste hydrochloric acid preferential-dissolving washing and filtering device comprises the following steps:
s1, conveying the waste materials to the inner side of a material containing box 3 through a conveying belt II 2, conveying the other part of the waste materials to the upper side of the material containing box 3 through a conveying belt I1, enabling the waste materials conveyed by the conveying belt I1 to fall into the inner side of the material containing box 3 in a free falling mode, enabling the waste materials conveyed by the conveying belt I1 to collide with the waste materials on the inner side of the material containing box 3, and crushing the waste materials;
s2, materials with proper size after crushing enter the inner side of the optimal dissolving box 8 through the material placing plate 4, hydrochloric acid is contained in the inner side of the optimal dissolving box 8, the material containing box 3 is impacted to move up and down to drive the middle of the screen 7 to move up and down, the screen 7 is deformed up and down, and the screen 7 stirs solution and waste materials on the inner side of the optimal dissolving box 8;
s3, after the hydrochloric acid is dissolved well, the solution filtered by the screen 7 does not flow to the upper part of the lower filter plate 16 through the water through holes, the lower filter plate 16 filters impurities in the solution, the movable plate 11 is pushed by the screen 7 to move upwards to drive the lower filter plate 16 to gradually move towards the upper filter plate 26, so that the impurities above the lower filter plate 16 are extruded by the lower filter plate 16 and the upper filter plate 26, the extrusion is finished, and the solution is completely collected.
The use method (working principle) of the invention is as follows:
when hydrochloric acid is soaked, waste with larger volume is conveyed from the upper part of a conveyor belt I1, waste with smaller volume is conveyed at the top end of a conveyor belt II 2 and conveyed to the inner side of a material containing box 3, when the waste at the top end of the conveyor belt I1 is dumped towards the inner side of the material containing box 3, the waste at the top end of the conveyor belt I1 carries out free falling motion, the waste with certain speed falls into the inner side of the material containing box 3, the material containing box 3 can slide downwards at the inner side of a fixed support plate 5 due to impact, meanwhile, other waste at the inner side of the material containing box 3 can move towards the lower part of the waste falling into the material containing box 3 due to magnetism, so that the waste is impacted, the size of the broken waste is reduced due to brittleness of the waste, and when a material containing plate 4 at the bottom end of the material containing box 3 is opened, the inboard waste material of flourishing magazine 3 is sieved out the waste material that is fit for the size by blowing board 4 and falls into the inboard of dissolving box 8 well, close blowing board 4 again, to dissolving box 8 well inboard let in hydrochloric acid, dissolve box 8 well inboard screen cloth 7 because of connecting through connecting rod 6, so connecting rod 6 drives screen cloth 7 and follows the downward slip of flourishing magazine 3, make screen cloth 7 at dissolving box 8 well inboard deformation down, and simultaneously, the spring of being connected between flourishing magazine 3 and the fixed extension board 5, make flourishing magazine 3 rebound once more, flourishing magazine 3 drives screen cloth 7 rebound through connecting rod 6 again, make screen cloth 7 rebound once more, deformation drives about screen cloth 7, it reciprocates to drive the waste material of screen cloth 7 top, thereby dissolve box 8 inboard hydrochloric acid solution of box through screen cloth 7 stirring well, and simultaneously, the removal is rocked to the waste material to the removal of screen cloth 7.
