Abstract
Description
Technical Field
[0001] This utility model relates to the field of carbon fiber pre-oxidation technology, specifically a carbon fiber pre-oxidation dust recovery system. Background Technology
[0002] Carbon fiber materials, due to their high flexural strength, tensile strength, corrosion resistance, and chemical resistance, are widely used in aerospace, defense, and satellite manufacturing. Large-tow carbon fiber shows promising application prospects in emerging industrial fields such as new energy vehicles, wind power generation, drones, and flying cars. How to achieve low-cost preparation of high-quality large-tow carbon fiber has become a research hotspot in the carbon fiber industry.
[0003] During the operation of carbon fiber pre-oxidation furnace, dust is continuously generated. Generally, dust removal equipment is used to discharge the dust from the pre-oxidation furnace to avoid interfering with the process. However, after the discharged dust is collected, it also needs to be processed further. During the dust collection and transportation process, there are issues related to dust explosion prevention.
[0004] Explosion-proofing of powder mainly focuses on the problem of dust being easily combusted and exploded under high temperature, high pressure or other conditions. Explosion-proofing technology of powder prevents dust explosions by controlling oxygen concentration, cutting off the combustion chain, and extinguishing ignition sources. Specific explosion-proof measures include dust sealing, dust removal, and reducing ignition sources.
[0005] In related technologies, when powders are transported, static electricity is generated by the transport equipment, which can accumulate in the powder conveying cavity. When the static electricity reaches a certain level, it can cause deflagration, leading to serious accidents.
[0006] Therefore, there is an urgent need to design a carbon fiber pre-oxidation dust recovery system to solve the technical problem that electrostatic accumulation during powder transportation may lead to deflagration accidents.

Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.
[0053] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0055] Based on the above research, and referring to Figure 4 This disclosure provides a carbon fiber pre-oxidation dust recovery system, including a storage chamber 1 and several static elimination mechanisms 2. The storage chamber 1 is suitable for storing and conveying powder materials. The several static elimination mechanisms 2 are evenly distributed on the inner wall of the storage chamber 1. The static elimination mechanisms 2 are used to guide the static electricity on the inner wall of the storage chamber 1 and release the static electricity through discharge operation, thereby avoiding the accumulation of static electricity in the storage chamber 1 and causing hazards.
[0056] Reference Figure 5 In at least one embodiment, the static eliminator 2 includes a conductive housing 21 and a storage and discharge assembly 22 disposed inside the conductive housing 21. One end of the conductive housing 21 is mounted on the storage compartment 1 via a conductive component, so that the storage compartment 1 is electrically connected to the conductive housing 21. The conductive housing 21 is electrically connected to the storage and discharge assembly 22. The static electricity guided by the conductive housing 21 is further transferred to the storage and discharge assembly 22. The storage and discharge assembly 22 can accumulate static electricity, and when the static electricity accumulates to a certain level, it performs a discharge operation to consume the static electricity, thereby achieving the effect of static eliminator.
[0057] Reference Figure 5 In at least one embodiment, the energy storage and discharge assembly 22 includes a solder ball 222 and at least one energy storage pin 221, with the solder ball 222 rolling within the conductive housing 21. Preferably, two energy storage pins 221 are provided, and the two energy storage pins 221 are mirror images of each other on both sides of the solder ball 222. One end of the energy storage pin 221 is connected to the conductive housing 21, and the other end faces the solder ball 222. When the energy storage pin 221 accumulates static electricity, it can attract the solder ball 222, causing the solder ball 222 to roll and adhere to the energy storage pin 221. After the energy storage pin 221 accumulates a certain amount of static electricity, it discharges, bouncing the solder ball 222 away, thus releasing the static electricity, and then the next cycle begins. The above-mentioned energy storage and discharge processes are all completed within the conductive housing 21, isolated from the environment of the storage compartment 1, thereby removing static electricity while avoiding affecting the environment containing powder, greatly reducing the harm caused by static electricity to the storage compartment 1. Further, referring to... Figure 5The storage and discharge assembly 22 includes two storage pins 221, which are respectively disposed on both sides of the conductive shell 21, sandwiching the solder ball 222 in the middle. At this time, static electricity can accumulate from both ends of the conductive shell 21 along the F1 direction and the F2 direction, respectively. The static electricity accumulated in the F1 direction accumulates along the F3 direction on the corresponding storage pin 221, thereby attracting the solder ball 222 and discharging after accumulating to a certain extent. On the other hand, the static electricity accumulated in the F3 direction accumulates along the F4 direction on the corresponding storage pin 221, thereby attracting the solder ball 222 and discharging after accumulating to a certain extent.
[0058] Reference Figure 1 In at least one embodiment, a splicing compartment 3 is provided on the opening side of the storage compartment 1. The splicing compartment 3 is used as an intermediate transition part when two storage compartments 1 are spliced together.
[0059] Reference Figure 2 In at least one embodiment, a control component 31 is provided on the outer side of the splicing compartment 3, and a barrier component 32 is provided on the inner side of the splicing compartment 3. The control component 31 and the barrier component 32 are connected by a transmission. In addition to serving as a connecting part to connect the two storage compartments 1, the splicing compartment 3 also needs to promptly isolate the two storage compartments 1 in the event of a deflagration in the storage compartment 1 to prevent the accident from escalating.
[0060] Reference Figure 3 In at least one embodiment, the barrier component 32 includes a barrier door 321 and connecting blocks 322 mirror-distributed on both sides of the barrier door 321. One end of the connecting block 322 is rotatably connected to the barrier door 321, and the other end is rotatably connected to the control component 31. The barrier door 321 is used to block the splicing compartment 3, thereby blocking two adjacent storage compartments 1. At the same time, rotating the connecting block 322 can drive the barrier door 321 to rotate, thereby opening or closing the barrier door 321, further achieving the effect of connecting the two storage compartments 1 or blocking the two storage compartments 1.
[0061] Reference Figure 3 In at least one embodiment, a plurality of counterweights 323 are provided on the side of the barrier door 321 away from the storage compartment 1. The counterweights 323 are all located at the head of the barrier door 321 so that in the normal state, the head of the barrier door 321 tilts downward and the tail tilts upward and fits against the top of the splicing compartment 3.
[0062] Reference Figure 2 In at least one embodiment, the control component 31 includes a support 311 and a control rod 312 rotatably mounted on the support 311, the control rod 312 being connected to the connecting block 322. When it is necessary to isolate the two spliced storage compartments 1, by pushing the control rod 312 downward, the control rod 312 can be driven to rotate the connecting block 322, thereby driving the head of the isolation door 321 to rise and the tail to fall, thus closing the spliced compartment 3.
[0063] Reference Figure 1 In at least one embodiment, a blower 4 is provided on the top of the storage chamber 1, and a gas supply pipe is installed at the output end of the blower 4. The gas supply pipe is connected to the interior of the storage chamber 1. Inert gas can be intermittently introduced into the storage chamber 1 by the blower 4 to reduce the ambient temperature inside the storage chamber 1 and reduce the oxygen content, thereby reducing the probability of powder deflagration.
