Description

Technical Field

[0001] This utility model relates to the field of nanocellulose application technology, and in particular to a nanocellulose 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

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 a nanocellulose 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.

[0032] Example 1

[0033] like Figures 1 to 5As shown, this embodiment provides a nanocellulose iron removal device, including a first temporary storage tank 20, an electromagnetic separator 21, a second temporary storage tank 1, a third temporary storage tank 2, a permanent magnet separator, a first feeding pump, and a second feeding pump. The outlet of the first feeding pump is connected to the inlet of the first temporary storage tank 20, the outlet of the first temporary storage tank 20 is connected to the inlet of the electromagnetic separator 21, the outlet of the electromagnetic separator 21 is connected to the first inlet of the second temporary storage tank 1, the first outlet of the second temporary storage tank 1 is connected to the first inlet of the permanent magnet separator, the first outlet of the permanent magnet separator is connected to the inlet of the third temporary storage tank 2, the first outlet of the third temporary storage tank 2 is connected to the inlet of the second feeding pump, the outlet of the second feeding pump is connected to the second inlet of the permanent magnet separator, and the second outlet of the permanent magnet separator is connected to the second inlet of the second temporary storage tank 1.

[0034] The nanocellulose 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 requiring ferromagnetic impurity removal by setting up a first temporary storage tank 20, a second temporary storage tank 1, and a third temporary storage tank 2. A first feed pump supplies the material to be removed from the first temporary storage tank 20. Then, an electromagnetic separator 21 is energized, and the material undergoes electromagnetic iron removal. The powerful electromagnetic separator 21 can remove most of the ferromagnetic impurities. The material processed by the electromagnetic separator 21 then enters the second temporary storage tank 1 through the first inlet, and further removes the remaining ferromagnetic impurities by a permanent magnet separator. Finally, a second... The feeding pump enables the material requiring the removal of ferromagnetic impurities to circulate between the second temporary storage tank 1, the permanent magnet separator, and the third temporary storage tank 2, achieving cyclic iron removal. The nanocellulose iron removal device provided in this embodiment combines the electromagnetic separator 21 with the permanent magnet separator. The electromagnetic separator 21 is used for efficient iron removal, and then the energy-saving permanent magnet separator is used for cyclic iron removal. By combining the advantages of the two separators, the iron removal efficiency is effectively improved, and the content of ferromagnetic impurities in the material is significantly reduced to an extremely low level. This 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, reduces energy consumption, shortens processing time, and improves production efficiency.

[0035] In a preferred embodiment of this invention, the electromagnetic separator 21 is provided with an iron removal port, which connects the interior of the electromagnetic separator 21 to the outside. Ferromagnetic impurities adsorbed by the electromagnetic separator 21 can be discharged from the iron removal port, achieving a very simple removal of accumulated ferromagnetic impurities, reducing equipment load, and ensuring the equipment's iron removal capacity. During use, the material pipeline can be temporarily closed and the electromagnetic separator 21 can be de-energized, causing the electromagnetic separator 21 to lose its magnetic force and its adsorption effect on ferromagnetic impurities. At this time, the ferromagnetic impurities can be discharged from the iron removal port. The second discharge port of the second temporary storage tank 1 is connected to the outside to facilitate the release of the material that has undergone iron removal treatment. The second discharge port of the third temporary storage tank 2 is also connected to the outside to facilitate the release of the material that has undergone iron removal treatment. The third discharge port of the third temporary storage tank 2 is connected to the inlet of the electromagnetic separator 21, so that when the content of ferromagnetic impurities in the material in the third temporary storage tank 2 is too high, the material in the third temporary storage tank 2 can be sent back to the electromagnetic separator 21 for electromagnetic iron removal.

[0036] Specifically, the electromagnetic separator 21 utilizes the current passing through the coil to generate a strong magnetic field, magnetizing the magnetic medium inside the separator into a strong magnet. This magnetic medium possesses a magnetic force several times stronger than that of a permanent magnet, generating a strong attraction to ferromagnetic impurities. Most of the ferromagnetic impurities in the material requiring removal are adsorbed onto the magnetic medium, achieving rapid and efficient preliminary iron removal, especially removing larger impurity particles. After processing by the electromagnetic separator 21, residual ferromagnetic impurities remain. These are then further adsorbed by permanent magnets in the permanent magnet separator, achieving gradient and staged iron removal. This combines the advantages of both separators, integrating energy consumption and efficiency, reducing workload, and lowering post-processing equipment maintenance costs. To ensure effective iron removal, the flow rate of the material requiring ferromagnetic impurities removal must be less than or equal to 50 L / min.

[0037] As a preferred embodiment of this invention, the processing procedure for the material after being treated by the electromagnetic separator 21 is as follows: The material treated by the electromagnetic separator 21 enters the second temporary storage tank 1, and then the material is transferred from the second temporary storage tank 1 to the permanent magnet separator. After the permanent magnet separator adsorbs some ferromagnetic impurities, the material in the permanent magnet separator is transferred to the third temporary storage tank 2. The inspector checks whether the ferromagnetic impurity content of the material in the third temporary storage tank 2 meets the requirements. If it meets the requirements, the material is discharged through the second discharge port of the third temporary storage tank 2. If the ferromagnetic impurity content exceeds the requirements significantly, the material in the third temporary storage tank 2 is sent back to the electromagnetic separator 21 for electromagnetic iron removal again. If the inspector finds that the ferromagnetic impurity content of the material in the third temporary storage tank 2 exceeds the required value, the material is then discharged again by the second feed pump. The material in the third temporary storage tank 2 is sent back to the permanent magnet separator for a second iron removal. After the second iron removal, the material returns to the second temporary storage tank 1. The inspector checks whether the ferromagnetic impurity content of the material in the second temporary storage tank 1 meets the requirements. If it does, the material is discharged through the second outlet of the second temporary storage tank 1. If the inspector finds that the ferromagnetic impurity content of the material in the second temporary storage tank 1 still exceeds the required value, the material enters the permanent magnet separator for a third iron removal from the second temporary storage tank 1. After the third iron removal, the material returns to the third temporary storage tank 2. The inspector checks whether the ferromagnetic impurity content of the material in the third temporary storage tank 2 meets the requirements, and then decides whether to discharge the material through the second outlet of the third temporary storage tank 2 or continue the iron removal cycle until the inspection is qualified and the iron removal process ends.

[0038] As a preferred embodiment of this invention, the permanent magnet separator includes several sub-separators 3 connected in series. The sub-separator 3 at the first end has a first feed port and a second feed port, and the sub-separator 3 at the last end has a first discharge port and a second discharge port, thereby achieving step-by-step iron removal and improving iron removal efficiency. If the number of sub-separators 3 exceeds two, the feed port of any intermediate sub-separator 3 needs to be connected to the discharge port of its preceding sub-separator 3, and its discharge port needs to be connected to the feed port of its following sub-separator 3.

[0039] As a preferred embodiment of this invention, there are two sub-iron separators 3. The discharge port of the sub-iron separator 3 at the first end is connected to the inlet port of the sub-iron separator 3 at the last end. The structure is simple and easy to manufacture and use.

The other end of the iron removal pipe is the discharge end 19, which is used to discharge material out of the iron removal pipe. The bottom end of each permanent magnet rod 9 extends into the iron removal pipe. The permanent magnet rod 9 has a strong magnetic force and can adsorb and gather ferromagnetic impurities, thereby reducing the content of ferromagnetic impurities in the material. It has low energy consumption and is easy to maintain. Each permanent magnet rod 9 is detachably fixedly connected to the iron removal pipe for easy disassembly and cleaning to remove the adsorbed ferromagnetic impurities and ensure the iron removal capacity. The feed end 18 is fixedly equipped with a feed filter, and the discharge end 19 is fixedly equipped with a discharge filter, which can filter and intercept larger particles.

If there are more than two sub-iron separators 3, the feed end 18 of the iron removal pipe in any of the intermediate sub-iron separators 3 needs to be connected to the discharge end 19 of the iron removal pipe in the next sub-iron separator 3, and the discharge end 19 of the iron removal pipe needs to be connected to the feed end 18 of the iron removal pipe in the next sub-iron separator 3.
