Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber thermal insulation material preparation, and in particular to a purification device and an operation method for preparing a carbon fiber thermal insulation material. Background Art

[0002] Carbon fiber thermal insulation material is a thermal insulation material made using the excellent properties of carbon fiber. Carbon fiber itself has excellent properties of high temperature stability, low thermal expansion coefficient, and low thermal conductivity, which makes it particularly effective in thermal insulation under high temperature environments. Functional materials such as carbon fiber felt made of carbon fiber have fiber filaments mainly arranged in a plane, and the fibers are connected by point contact, which can effectively reduce the heat transferred by the heat conduction path. At the same time, the overall structure of the carbon fiber felt is loose and porous, and the thermal radiation waves are constantly reflected and dissipated inside, further reducing the heat transmitted by thermal radiation. Therefore, carbon fiber thermal insulation materials have been widely used in high temperature environments such as photovoltaic thermal fields, heat treatment equipment, and semiconductor thermal fields. With the rapid development of the new energy industry, especially the booming photovoltaic power generation industry, the demand for high-performance thermal field thermal insulation materials is growing. Carbon fiber thermal insulation materials have become an indispensable key material in this field due to their unique performance advantages.

[0003] In the preparation process of carbon fiber thermal insulation materials, purification is a crucial link. However, traditional purification technology has many shortcomings, which have an adverse effect on material properties and production efficiency. First, traditional purification technology often adopts high-temperature chemical treatment, which not only requires extremely high processing temperature, but also takes a long time, increasing production costs and energy consumption. Secondly, during the high-temperature treatment process, too many pore structures are easily formed on the surface of carbon fiber. Although these pore structures provide pathways for the diffusion of subsequent reaction gases, too many pore structures will reduce the material's antioxidant properties and affect the material's service life and stability. In addition, traditional purification technology may also cause damage to the fiber structure, resulting in a decrease in fiber strength, thereby affecting the overall performance of the thermal insulation material. These problems not only reduce the quality of carbon fiber thermal insulation materials, but also limit their application in large-scale industrial production. Therefore, it is particularly important to develop a high-efficiency, environmentally friendly, and low-cost purification equipment for the preparation of carbon fiber thermal insulation materials. To this end, we propose a purification equipment and operation method for the preparation of carbon fiber thermal insulation materials. Summary of the invention

[0032] Working principle: First, the raw material of carbon fiber thermal insulation material to be purified is put into the purification bin 2 through the feed inlet 8. The dust cover 801 is set at the top of the feed inlet 8, which can effectively block the entry of external dust, impurities and other possible pollutants during non-feeding periods, thus maintaining the purity of the raw material to the greatest extent. The design of the feed inlet 8 is very delicate, and its bottom end precisely extends into the processing bin 1 and communicates with the purification bin 2. This seamless docking structure ensures that the raw material can enter the purification bin 2 accurately and without omission, avoiding the loss and waste of the raw material during the feeding process and reducing the poor purification effect that may be caused by improper feeding. Subsequently, the driving motor 203 is started. The output end of the driving motor 203 is tightly connected to the transmission rod 3. Through this efficient linkage mechanism, the driving motor 203 can strongly drive the transmission rod 3 to rotate stably and at high speed. The multiple groups of stirring blades 301 evenly distributed on the outer side of the transmission rod 3 also rotate synchronously. It is worth mentioning that rectangular through holes are carefully arranged inside the stirring blades 301. During the rotation process, relying on their unique design and high-speed rotation, the stirring blades 301 generate a powerful stirring force, achieving a full, detailed and all-round stirring effect on the raw material. This efficient stirring action enables the raw material to be evenly distributed in the purification bin 2, eliminating the possible phenomena of local accumulation and uneven distribution of the raw material, laying a solid and uniform foundation for the subsequent purification operation, and greatly improving the efficiency and quality of purification. During the continuous stirring, the raw material starts the key screening and separation steps in the purification bin 2. A sieve plate 201 is carefully set inside the purification bin 2, and a special isolation bin 202 is also provided outside the sieve plate 201. The through holes evenly distributed on the outer side of the sieve plate 201 are carefully designed in terms of size range, which is generally between 2 mm and 20 mm. Driven by the stirring, particles of different sizes will be preliminarily separated rigorously and effectively according to the precise size of the through holes. The smaller particles, relying on their size advantages, smoothly pass through the sieve plate 201 and enter the isolation bin 202, while the larger particles are left above the sieve plate 201 due to size limitations. To ensure the tightness and reliability of the screening process, the connection between the purification bin 2 and the sieve plate 201 is carefully sealed with a high-quality rubber ring, thus effectively ensuring that no leakage occurs during the screening process and ensuring the accuracy and purity of the separation. After the above preliminary screening, the material is further separated and purified under the continuous stirring action. When the material meets the purification requirements, it is discharged through the discharge pipe 4. A powerful control valve 401 is provided outside the discharge pipe 4. Through the precise control of the control valve 401 by the operator, the opening and closing of the discharge pipe 401 and the fine adjustment of the flow rate can be flexibly achieved. The bottom end of the discharge pipe 4 is tightly connected to the storage tank 5, enabling the purified material to smoothly enter the storage tank 5. Two groups of heating pipes 501 are provided at both ends inside the storage tank 5, and efficient heating wires 502 are equipped inside each heating pipe 501.Through the uniform and stable heating effect generated by the heating wire 502, the purified material is further deeply processed, such as effectively drying the material and removing possible residual trace impurities, thereby further improving the quality and purity of the material. In the entire complex and delicate purification process, some gases are inevitably produced. At this time, the exhaust component 9 located at the top right side of the processing chamber 1 begins to play its key role. Three groups of filter plates 902 are equidistant and cleverly arranged inside the exhaust box 901, and well-designed slides are equidistant on both sides of the exhaust box 901. The filter plate 902 can be easily installed in the slide. This design not only facilitates the removal and replacement of the filter plate, but also ensures the stability and reliability of the filter plate during operation. The mesh number of the three groups of filter plates 902 is scientifically designed and gradually increased, so that the exhausted gas is filtered and purified layer by layer and step by step. A special exhaust pipe 903 is provided on the top of the exhaust box 901. The gas after multi-layer filtration and purification can be safely and environmentally friendly discharged through the exhaust pipe 903, thereby perfectly achieving environmentally friendly exhaust. In addition, a disassembly plate 101 is provided on the front of the processing chamber 1. This design greatly facilitates the staff to carry out regular inspection and timely maintenance of the internal equipment. An observation window 102 is also provided on the front of the disassembly plate 101. This design provides great convenience for the operator, enabling him to observe the internal purification situation intuitively at any time, so as to adjust the operating parameters timely and accurately according to the actual situation, and ensure that the purification process is always in the best state. A support rod 6 is firmly provided at the bottom of the outer side of the processing chamber 1, and a sturdy fixed seat 601 is provided at the bottom of the support rod 6, which together provide a solid, stable and reliable support for the entire equipment. A practical cover plate 7 is also provided on the top of the fixed seat 601, and a movable arc plate 701 with convenient operation is provided on the front of the cover plate 7, which is convenient for the staff to carry out related operations. An anti-slip pad 702 is provided at the bottom of the inner side of the cover plate 7, which effectively increases the friction with the ground, significantly improves the stability of the equipment during operation, and minimizes the potential safety hazards and poor purification effects caused by equipment shaking or displacement.
