A kind of silica ultrafine powder iron removal device

Abstract

The invention discloses a white carbon black ultramicro fine powder iron removal device which comprises an iron removal tank body and a flange, wherein the iron removal tank body comprises a tank top, a tank body and a tank bottom, wherein a feed opening is formed in the tank top of the iron removal tank body; a discharging opening is formed in the tank bottom; the flange is connected to the feed opening; a plurality of magnetic rods are arranged on the tank body; the white carbon black ultramicro fine powder iron removal device further comprises an air blowing mechanism; the air blowing mechanism comprises an air blower, an air blowing pipe and air distributing devices; the air distributing devices are mounted at the tank bottom; one end of the air blowing pipe is connected onto the air distributing devices, and the other end of the air blowing pipe is connected onto the air blower; a feeding spiral is mounted in the iron removal tank body; one end of the feeding spiral is connected with the tank top, and the other end of the feeding spiral is connected with the tank bottom; the feeding spiral is connected with a driving motor, and comprises a rotating shaft and helical teeth; the helical teeth are welded on the rotating shaft; the rotating shaft is connected with the output shaft of the driving motor. When the white carbon black ultramicro fine powder iron removal device is used for iron removal, the white carbon black powder is dispersed, and all iron-containing materials are in contact with the magnetic rods and are absorbed away by the magnetic rods, so that the iron-containing materials in the white carbon black powder can be removed completely.

Description

technical field [0001] The invention relates to equipment for producing white carbon black, in particular to a device for removing iron from white carbon black superfine powder. Background technique [0002] White carbon black is the general term for white powder X-ray amorphous silicic acid and silicate products, mainly refers to precipitation Silica, fumed silica, ultrafine silica gels and aerogels, also including powdered synthetic aluminum silicates and calcium silicate Wait. Silica is Porous Sexual substances, the composition of which can be SiO 2 ·nH 2 O represents, where nH 2 O exists in the form of surface hydroxyl groups. Soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustible, tasteless, odorless, with good electrical insulation. [0003] Precipitated silica is a widely used fine chemical product, mainly used in rubber, silicone rubber, plastics, coati...

Problems solved by technology

[0006] In this invention, when the iron removal box is discharged, due to the large feed amount of white carbon black powder and the water content in the primary powder, the powder outlet is blocked and cannot be discharged normally.
