Description

Technical Field

[0001] This utility model relates to the field of nanocellulose application technology, and in particular to an iron removal device. Background Technology

[0002] A novel material, typically a few nanometers in diameter and tens to several micrometers in length, can be prepared from plant biomass using chemical, physical, or biological methods. It can be rod-shaped, fibrous, or stringy. Because cellulose is the main component, this material is often collectively referred to as nanocellulose. Nanocellulose not only possesses the characteristics of biomass materials, such as low density, good biocompatibility, biodegradability, and renewability, but also exhibits advantages such as high crystallinity, high Young's modulus, high thermal stability, and low coefficient of thermal expansion. It has shown great potential in high-performance, functional, and high-value-added product applications, significantly improving the utilization value and product benefits of biomass.

[0003] In fields such as battery separators, the materials used must not contain a large number of ferromagnetic impurities to avoid abnormal conductivity and corrosion. Untreated nanocellulose contains a significant amount of ferromagnetic impurities. When nanocellulose is used as a structural component, these impurities can cause defects in products and even pose significant safety hazards, limiting its application. Therefore, it is necessary to treat nanocellulose to remove ferromagnetic impurities.

[0004] High-power electromagnetic separators are commonly used in fields such as iron removal in mining and waste treatment. They are usually complex in structure, have high installation and maintenance costs, and require stable high-power power support during use, resulting in high energy consumption and large power consumption. In contrast, traditional permanent magnet separators have low iron removal efficiency and cannot meet the needs of industrial production. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The purpose of this invention is to provide an iron removal device to solve the problems existing in the prior art, effectively improve iron removal efficiency, and have a simple structure that is easy to install, maintain and use.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The iron removal device provided in this embodiment is particularly suitable for solving the problem of nanocellulose containing a large amount of ferromagnetic impurities. It temporarily stores the material for which ferromagnetic impurities need to be removed by setting up a first temporary storage tank 1 and a second temporary storage tank 2. A first feeding pump supplies the material for which ferromagnetic impurities need to be removed into the first inlet of the first temporary storage tank 1. A permanent magnet separator removes the ferromagnetic impurities from the material. Furthermore, the first and second feeding pumps circulate the material for which ferromagnetic impurities need to be removed among the first temporary storage tank 1, the permanent magnet separator, and the second temporary storage tank 2, achieving cyclic iron removal. This effectively improves iron removal efficiency, significantly reduces the content of ferromagnetic impurities in the material, improves the quality and performance of the material, expands its application range, and features a simple structure that is easy to install, maintain, and use.

[0036] In a preferred embodiment of this invention, the first feed pump delivers the material to be demagnetized (ferromagnetic impurities removed) into the first temporary storage tank 1. The material is then transferred from the first temporary storage tank 1 to a permanent magnet separator. After the permanent magnet separator adsorbs some of the ferromagnetic impurities, the material in the permanent magnet separator is transferred to the second temporary storage tank 2. The inspector checks whether the ferromagnetic impurity content of the material in the second temporary storage tank 2 meets the requirements. If it does, the material is discharged through the second outlet of the second temporary storage tank 2. If the inspector detects that the ferromagnetic impurity content of the material in the second temporary storage tank 2 is within acceptable limits... If the impurity content still exceeds the required value, the material in the second temporary storage tank 2 is sent back to the permanent magnet separator for a second iron removal via the second feed pump. After the second iron removal, the material returns to the first temporary storage tank 1 and then enters the permanent magnet separator for a third iron removal. After the third iron removal, the material returns to the second temporary storage tank 2. The inspector checks whether the ferromagnetic impurity content of the material in the second temporary storage tank 2 meets the requirements, and then decides whether to discharge the material through the second outlet of the second temporary storage tank 2 or continue the iron removal process until the inspection is qualified.
