This utility model relates to the field of boron carbide processing technology, specifically to an iron removal device for boron carbide processing. It mainly addresses the problems of iron falling off and poor iron removal due to excessive material falling speed, and proposes the following technical solution: It includes a feeding tray, which is equipped with a material unloading component. The unloading component includes a straight pipe connected to the surface of the feeding tray. A first suction stone is fixed to the inner wall of the straight pipe, and a unloading ball is inserted into the side of the first suction stone. A spiral pipe is connected to the bottom of the straight pipe, and the bottom of the first suction stone is aligned with the bottom of the spiral pipe. An iron removal component is fitted into the spiral pipe. This utility model, with the first suction stone on the inner wall of the straight pipe and the unloading ball inserted into the side of the first suction stone, can fully adsorb and remove iron from the boron carbide material while ensuring smooth falling, solving the problem of insufficient contact between the magnetic component and the material, and improving the efficiency of adsorption and impurity removal.

The application provides an arrangement structure of anti-fluidization medium pieces, which comprises a medium piece array in a magnetic medium box; one end of the magnetic medium box is a slurry input end, and the other end is a slurry output end; the medium piece array is arranged by three or more medium pieces; in the upward view of the slurry flow direction of the magnetic medium box, the three adjacent medium pieces are arranged in a non-isosceles triangle layout which can destroy the fluidization movement rule of the slurry, so as to increase the collision probability of the magnetic particles in the slurry and the medium pieces; the arrangement method of the application can effectively increase the adsorption area, destroy the slurry flow rule, and significantly improve the separation efficiency of the high-gradient magnetic separator.

This application provides a range hood, which includes a fan, a smoke collection hood, and a smoke exhaust duct. The fan's air inlet is connected to the smoke collection hood, and the fan's air outlet is connected to the smoke exhaust duct. The fan's air outlet is provided with an air multiplier structure, and the fan's air outlet is connected to the smoke exhaust duct through the air multiplier structure. The air multiplier structure includes an inner ring guide structure and an outer ring guide structure. The outer ring guide structure is arranged around the outer side wall of the inner ring guide structure, and an annular guide cavity is formed between the outer side wall of the inner guide structure and the inner side wall of the outer guide structure. The fan's air outlet is connected to the smoke exhaust duct through the annular guide cavity. This application provides a range hood that can increase airflow, expand the range of oil fume adsorption, and improve smoke extraction efficiency.

The utility model relates to the technical field of metal scraps, in particular to a metal scrap machining device which comprises a shell and a feeding port formed in the top of the shell, a crushing assembly is arranged at the bottom of the feeding port, a screening assembly is arranged at the bottom of the crushing assembly, and two first containing grooves which are vertically arranged are formed in the position, close to the left end, of the bottom of the screening assembly. A separating assembly used for conducting magnetic attraction separation on the metal scraps is arranged at the position, corresponding to the first containing groove, in the shell, cleaning assemblies are symmetrically arranged in the first containing groove in the front-back direction, the crushing assembly is arranged at the feeding port to crush the metal scraps, so that the size of the metal scraps is reduced, and the metal scraps are matched with a screen plate with a vibration motor; the situation that metal scraps larger than meshes are clamped on the screen plate is reduced, two sets of cylindrical cams are arranged in the shell up and down, electromagnetic suction plates with different vertical positions are placed between the cylindrical cams, and a rotating motor is started to drive the electromagnetic suction plates to horizontally move back and forth, so that the suction range of the electromagnetic suction plates is enlarged.
