Embodiment 1

[0040] A desiliconization mud cake pretreatment device for iron oxide production, including a mud cake crusher 1, a beating mechanism I3, a rinsing and filtering mechanism 5, a beating mechanism II7, a centrifuge 9, and a mud cake crusher 1 arranged in sequence along the treatment process The output end of the beating mechanism I3 is connected to the beating mechanism I3 through the mud pipe I2, the output end of the beating mechanism I3 is connected to the rinsing and filtering mechanism 5 through the mud pipe II4, and the output end of the rinsing and filtering mechanism 5 is connected to the beating mechanism II7 through the mud pipe III6. The output end of the beating mechanism II7 is connected with the centrifuge 9 through the mud pipe IV8;

[0041] In this example, if figure 2 As shown, the output end of the mud pipe I2 is connected with a water delivery pipe I202, and the other end of the water delivery pipe I202 is connected with an external water source, and a water ...

Embodiment 2

[0054] The difference between this embodiment and embodiment 1 is that, as image 3 As shown, the lower part of the inner cavity of the tank body 301 of the beating mechanism I3 and the beating mechanism II7 is equipped with a plurality of electric heating plates 304 distributed in a circular array along the inner wall. The specifications of the beating mechanism I3 and the beating mechanism II7 are consistent. It can be understood that, The beating mechanism Ⅱ7 is also equipped with a circular array of electric heating plates, which are heated when the mud cake is beating. The increase in temperature can effectively improve the beating efficiency, ensure the mixing of mud and water, and improve the fineness of the mud.

[0055] Refer to Example 1 for other undescribed structures.

[0056] The above-mentioned desiliconization mud cake pretreatment device for iron oxide production provided in this example breaks the mud cake first through the mud cake crusher 1, so that the dry...

Abstract

The invention relates to the technical field of iron oxide production equipment, provides a silicon-free mud cake pretreatment device for iron oxide production, and aims to solve the problems that silicon-free mud cakes contain a large number of granular impurities, silicon-free mud cakes need to be pretreated firstly; the purity of the silicon-free mud cakes is ensured. The device comprises a mudcake crusher, a pulping mechanism I, a rinsing and filtering mechanism, a pulping mechanism II and a centrifuge, which are sequentially arranged along a treatment process. The output end of the mud cake crusher is connected with the pulping mechanism I through a mud pipe I, the output end of the pulping mechanism I is connected with the rinsing and filtering mechanism through a mud pipe II, the output end of the rinsing and filtering mechanism is connected with the pulping mechanism II through a mud pipe III, and the output end of the pulping mechanism II is connected with the centrifuge through a mud pipe IV; and a water conveying pipe I is mounted at the output end of the slurry pipe I in a penetrating manner. The device is especially suitable for pretreatment of silicon-free mud cakes,and has a high social use value and application prospect.

Description

technical field [0001] The invention relates to the technical field of iron oxide production equipment, in particular to a desiliconization mud cake pretreatment device for iron oxide production. Background technique [0002] Iron oxide, chemical formula Fe2O3, also known as burnt limonite, burnt ocher, iron red, iron red, red powder, etc. Appearance is reddish-brown powder, soluble in strong acid, medium strong acid, its reddish-brown powder is a low-grade pigment, industrially called iron oxide red, used in paint, ink, rubber and other industries, can be used as a catalyst, glass, gemstone, Metal polishing agent can be used as iron-making raw material. [0003] Desiliconization mud cake is the filter waste produced by the desiliconization device when the waste acid after pickling the steel plate is used to produce magnetic iron oxide red. Pickling of strip steel is an indispensable process in the cold rolling production line. After pickling of strip steel, a large amount...
