Embodiment 1

[0017] Embodiment 1: take sulfuric acid slag as raw material to prepare iron oxide red process washing pool, it comprises pool body 1, water inlet pipe 2 and water outlet pipe 3, described pool body is internally connected with a horizontally distributed elastic connector 4, A number of pendants 5 are movably connected to the transverse elastic connector. The pendant is in the shape of a roller, and the center of the roller is penetrated by the transverse elastic connector, so that the roller can move back and forth on the transverse elastic connector. Distributed longitudinal elastic connectors 6, the longitudinal elastic connectors are connected to the pendant in one-to-one correspondence. The water inlet pipe is located at one side of the pool body, and the water outlet pipe is located at the bottom of the pool body.

Embodiment 2

[0018] Embodiment 2: The difference from Embodiment 1 is that the surface of the roller is evenly distributed with tooth-shaped protrusions 7, which can drive the liquid to generate turbulence when the roller rotates, further enhance the liquid fluctuation at the bottom of the pool, and avoid iron oxide deposition.

Embodiment 3

[0019] Embodiment 3: The difference from Embodiment 1 is that the pendant is spherical and has tooth-shaped protrusions evenly distributed on the surface.

Abstract

The invention discloses a water washing tank for the preparation of iron oxide red by using sulfuric acid slag as a raw material. The horizontal elastic connecting piece (4), several hanging pieces (5) are movably connected to the horizontal elastic connecting piece, and vertically distributed longitudinal elastic connecting pieces (6) are arranged at the bottom of the pool body. The pendants are connected one by one. The beneficial effect of the invention is that by arranging a pendant that can move up, down, left and right at the bottom of the pool body, when the iron oxide and water are mixed and flowed into the pool body through the water inlet pipe, a disturbing force will be generated to make the pendant move up and down, because the pendant is moved up and down by the transverse elastic connecting piece and the The longitudinal elastic connector is constrained, so that the pendant can be displaced in the horizontal and vertical directions, thereby stirring the iron oxide deposited at the bottom of the pool and improving the washing effect of the iron oxide.

Description

technical field [0001] The invention relates to a process for preparing iron oxide red by using sulfuric acid slag as a raw material, in particular to a water washing pool for the wet iron oxide red process. Background technique [0002] Iron oxide (Ferric oxide), chemical formula Fe 2 o 3 . Red or dark red amorphous powder. The relative density is 5-5.25, and the melting point is 1565°C (decomposition at the same time). Insoluble in water, soluble in hydrochloric acid and sulfuric acid, slightly soluble in nitric acid. It has strong hiding power and tinting power, no oil and water permeability. Stable in the atmosphere and sunlight, resistant to dirty gas, high temperature and alkali. Preparation methods include wet and dry methods. The wet-process products have fine crystals, soft particles, are easier to grind, and are easy to be used as pigments. Dry-process products have large crystals and hard particles, which are suitable for magnetic materials and polishing a...
