AI Technical Summary
Existing iron oxide red washing devices suffer from several problems during the washing process. The stirring mechanism cannot move up and down, causing particles to accumulate at the bottom and forming a "washing dead zone." Soluble impurities are difficult to dissolve, and the filtration and separation mechanism cannot adjust with changes in the liquid level, resulting in low efficiency and impurity residue.
A water washing moving mechanism drives the stirring mechanism to move up and down inside the water washing cylinder. Combined with a water washing adjustment mechanism, the position of the filter cylinder is dynamically adjusted to improve the uniformity of stirring and the filtration efficiency. The stirring motor drives the stirring frame to rotate and move, and the adjustment motor drives the filter cylinder to move up and down to ensure full contact between solid and liquid and effective separation of impurities.
It improves the efficiency and purity of iron oxide red washing, reduces washing dead zones and impurity residue, shortens washing time, reduces water consumption, and enhances solid-liquid separation effect.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of iron oxide red production technology, and in particular relates to an iron oxide red water washing device. Background Technology
[0002] The water washing process for iron oxide red is a crucial step in removing impurities (such as soluble salts, residual acids / alkalis, and fine dust) during production, directly affecting product purity, color, and application performance (such as corrosion resistance in coatings). The core of water washing is to dissolve impurities in water through solid-liquid contact, followed by purification through solid-liquid separation.
[0003] However, in existing washing devices, the stirring mechanism cannot move up and down during the washing process, making it difficult to cover different depths of the liquid. Particles at the bottom are prone to deposit, forming "washing dead corners." Soluble impurities (such as salt) cannot be fully dissolved, requiring extended washing time or more washes, resulting in low efficiency. Furthermore, the position of the filtration and separation mechanism is fixed and cannot be adjusted according to changes in the liquid level, which can easily lead to "dry filtration" or insufficient filtration of the sediment layer, with residual impurities remaining with the filter cake. Summary of the Invention
[0004] This utility model provides an iron oxide red water washing device to solve the problems in the prior art.
[0005] The present invention adopts the following technical solution: an iron oxide red water washing device, comprising a water washing cylinder, a water washing filter cylinder, a water washing moving mechanism, a water washing stirring mechanism, and a water washing adjusting mechanism. The top of the water washing cylinder is provided with a mounting frame, the water washing moving mechanism is mounted on the mounting frame, the water washing stirring mechanism is mounted on the water washing moving mechanism, the water washing moving mechanism can drive the water washing stirring mechanism to move up and down inside the water washing cylinder, the water washing filter cylinder is located inside the water washing cylinder, and the water washing adjusting mechanism is located on the top of the water washing cylinder, the water washing adjusting mechanism can drive the water washing filter cylinder to move up and down inside the water washing cylinder.
[0006] Furthermore, the water washing moving mechanism includes a moving plate and two moving slide modules. The two moving slide modules are symmetrically arranged on the inner side wall of the mounting frame, and the two ends of the moving plate are connected to the moving ends of the two moving slide modules.
[0007] Furthermore, the water washing and stirring mechanism includes a stirring motor and a stirring frame. The stirring motor is located on the top of the moving plate, the top of the stirring frame is rotatably connected to the moving plate, and the stirring frame is drivenly connected to the main shaft of the stirring motor.
[0008] Furthermore, the bottom of the water washing filter cylinder is provided with a filter screen plate, and the water washing filter cylinder is provided with two upright plates. One of the upright plates is provided with two sliding rods, and the outer wall of the water washing cylinder is provided with a sliding seat that slides with the two sliding rods. The other upright plate is provided with two sliding grooves, and the inner wall of the water washing cylinder is provided with a sliding block that slides with the two sliding grooves.
[0009] Furthermore, the water washing adjustment mechanism includes an adjustment motor and an adjustment gear. The adjustment motor is located at the top of the water washing drum, and the adjustment gear is connected to the main shaft of the adjustment motor. The vertical plate is provided with a toothed plate that meshes with the adjustment gear.
[0010] Furthermore, the washing drum is equipped with a water outlet pipe, and the water outlet pipe is equipped with a valve.
[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: Firstly, in the washing and stirring of iron oxide red, the stirring motor drives the stirring frame to rotate on the moving plate. The stirring frame rotates inside the washing drum, thus stirring the iron oxide red and water. During stirring, the two moving slide modules work simultaneously, causing the rotating stirring frame to move up and down along the axis of the washing drum. This improves the uniformity of stirring: the up-and-down movement covers different depths of the washing drum, avoiding bottom sedimentation or insufficient mixing at the top caused by fixed stirring, ensuring full contact between the iron oxide red particles and the washing water, and accelerating the dissolution of soluble impurities; it reduces washing dead zones: the movement washes away residual material on the drum wall and in corners, preventing particle agglomeration or impurity adhesion, reducing the risk of localized impurity residue; and it optimizes solid-liquid contact efficiency: the dynamic stirring path increases the relative movement of particles and water, promoting the diffusion of impurities from particle pores into the water, shortening washing time, and reducing water consumption.
[0012] Secondly, when filtering and separating impurities in the stirred iron oxide red, this utility model uses a filter screen on the water-washing filter cylinder to filter the impurities. During filtration, the motor drives the adjusting gear to rotate on the toothed plate on the vertical plate, thereby moving the vertical plate on the water-washing filter cylinder up and down on the sliding base via two sliding rods. This adapts to changes in liquid level and improves filtration efficiency. The filter screen position can be dynamically adjusted according to the liquid level, avoiding the problem of "dry filtration" due to a drop in liquid level or insufficient filtration of impurities due to an excessively high liquid level. This ensures that the filter screen is always in effective contact with the liquid, accelerating solid-liquid separation. It also reduces filter cake accumulation and lowers the risk of clogging: the up-and-down movement loosens the iron oxide red filter cake on the surface of the filter screen, reducing filter screen clogging caused by tightly packed particles. At the same time, the slight vibration generated by the movement promotes the seepage of residual waste liquid in the filter cake, improving filtration permeability. Furthermore, it enhances the impurity removal effect: the movement can wash away residual impurities on the edge of the filter screen and the inner wall of the water-washing cylinder, reducing material accumulation in dead corners of the equipment, avoiding secondary contamination of the filter cake by impurities, and improving product purity.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] The technical solution of the iron oxide red water washing device provided by the present invention will be described in detail below with reference to the accompanying drawings.
[0016] Reference Figures 1 to 6 As shown in the figure, this utility model embodiment provides an iron oxide red water washing device, including a water washing cylinder 1, a water washing filter cylinder 2, a water washing moving mechanism 3, a water washing stirring mechanism 4, and a water washing adjusting mechanism 5. The top of the water washing cylinder 1 is provided with a mounting frame 10, the water washing moving mechanism 3 is mounted on the mounting frame 10, the water washing stirring mechanism 4 is mounted on the water washing moving mechanism 3, the water washing moving mechanism 3 can drive the water washing stirring mechanism 4 to move up and down inside the water washing cylinder 1, the water washing filter cylinder 2 is located inside the water washing cylinder 1, and the water washing adjusting mechanism 5 is located on the top of the water washing cylinder 1, the water washing adjusting mechanism 5 can drive the water washing filter cylinder 2 to move up and down inside the water washing cylinder 1.
[0017] During the washing process, iron oxide red is placed inside the washing filter cylinder 2, and then the washing water is delivered into the washing filter cylinder 2 to wash the iron oxide red.
[0018] Specifically, the water washing moving mechanism 3 includes a moving plate 31 and two moving slide modules 32. The two moving slide modules 32 are symmetrically arranged on the inner side wall of the mounting frame 10. The two ends of the moving plate 31 are connected to the moving ends of the two moving slide modules 32. The water washing stirring mechanism 4 includes a stirring motor 41 and a stirring frame 42. The stirring motor 41 is located on the top of the moving plate 31. The top of the stirring frame 42 is rotatably connected to the moving plate 31. The stirring frame 42 is drivenly connected to the main shaft of the stirring motor 41.
[0019] During the washing and stirring of iron oxide red, the stirring motor 41 drives the stirring frame 42 to rotate on the moving plate 31. The stirring frame 42 rotates inside the washing drum 1, thus stirring the iron oxide red and water. During stirring, the two moving slide modules 32 work simultaneously, causing the rotating stirring frame 42 to move up and down along the axis of the washing drum 1. This improves the uniformity of stirring: the up and down movement can cover different depth areas of the washing drum 1, avoiding bottom sedimentation or insufficient mixing at the top caused by fixed stirring, ensuring full contact between the iron oxide red particles and the washing water, and accelerating the dissolution of soluble impurities; reducing washing dead corners: the movement can flush away residual materials on the drum wall and corners, preventing particle agglomeration or impurity adhesion, and reducing the risk of local impurity residue; optimizing solid-liquid contact efficiency: the dynamic stirring path increases the relative movement between particles and water, promoting the diffusion of impurities from particle pores into the water, shortening the washing time, and reducing water consumption.
[0020] Specifically, the bottom of the water washing filter cylinder 2 is provided with a filter screen plate 21, and the water washing filter cylinder 2 is provided with two upright plates 22. One of the upright plates 22 is provided with two sliding rods 23. The outer wall of the water washing cylinder 1 is provided with a sliding seat 24 that slides with the two sliding rods 23. The other upright plate 22 is provided with two sliding grooves 25. The inner wall of the water washing cylinder 1 is provided with a sliding block that slides with the two sliding grooves 25. The water washing adjustment mechanism 5 includes an adjustment motor 51 and an adjustment gear 52. The adjustment motor 51 is located at the top of the water washing cylinder 1. The adjustment gear 52 is connected to the main shaft of the adjustment motor 51. The upright plate 22 is provided with a toothed plate 53 that meshes with the adjustment gear 52.
[0021] When filtering and separating impurities in the stirred iron oxide red, the impurities are filtered through the filter screen 21 on the water-washed filter cylinder 2. During filtration, the adjusting motor 51 drives the adjusting gear 52 to rotate on the toothed plate 53 on the vertical plate 22, thereby causing the vertical plate 22 on the water-washed filter cylinder 2 to move up and down on the sliding base 24 via two sliding rods 23. This adapts to changes in liquid level and improves filtration efficiency. The filter screen position can be dynamically adjusted according to the liquid level, preventing the fixed filter screen from "dry filtering" due to a drop in liquid level. To address issues such as insufficient filtration of impurities due to excessively high liquid levels, this system ensures the filter screen remains in effective contact with the liquid, accelerating solid-liquid separation. It also reduces filter cake buildup and the risk of clogging: the up-and-down movement loosens the iron oxide red filter cake on the filter screen surface, reducing clogging caused by tightly packed particles. Simultaneously, the slight vibration generated by the movement promotes the seepage of residual waste liquid from the filter cake, improving filtration permeability. Furthermore, it enhances impurity removal: the movement washes away residual impurities from the filter screen edges and the inner wall of the washing cylinder, reducing material accumulation in dead corners, preventing secondary contamination of the filter cake, and improving product purity.
[0022] It should be noted that the stirring frame 42 and the water washing filter 2 move up and down synchronously.
[0023] Specifically, the washing drum 1 is provided with a water outlet pipe 11, and the water outlet pipe 11 is provided with a valve 12; after the iron oxide red is washed, the valve 12 is opened and the washing water is discharged outward through the water outlet pipe 11.
[0024] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
