[0002] In the production process of SiC fibers and their composites, short, broken fibers are easily scattered on the ground or in low-lying areas due to processing and cutting. Traditional manual cleaning methods are not only inefficient but also fail to completely remove micron-sized fibers. Residual fibers may harm the human respiratory system and mix into the product, forming impurities and seriously affecting material performance. Existing adsorption equipment mostly uses single vacuum or electrostatic adsorption technologies, which have insufficient adaptability: vacuum adsorption has poor coverage in narrow areas, and electrostatic adsorption is prone to efficiency reduction due to fiber adhesion.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides an automated adsorption-type collection device for SiC short and broken fibers, such as... Figure 1 As shown ( Figure 1 The dashed lines represent circuits and information transmission links, including an autonomous moving chassis, an adsorption module, a multi-stage filtration and storage module, and an intelligent control system. The autonomous moving chassis is used to adjust the adsorption height and position. The adsorption module uses a combination of electrostatic adsorption and vacuum adsorption to adsorb short SiC fibers. The multi-stage filtration and storage module is used to separate and collect short SiC fibers, dust, and impurities. The intelligent control system is used to monitor environmental parameters and dynamically adjust the operating mode.

[0028] The autonomous mobile chassis includes a SLAM navigation module 19 for positioning and dynamic obstacle avoidance, an ultrasonic radar module 2, and drive wheels 1. The SLAM navigation module 19, combined with the ultrasonic radar module 2, can achieve precise positioning of ±2cm, supporting dynamic obstacle avoidance and area-focused cleaning modes. The autonomous mobile chassis is also equipped with a lifting mechanism 3, a contamination concentration sensor 18, and an anti-collision sensor. The lifting mechanism 3 can vertically adjust the height of the adsorption module from 0-0.5m to adapt to the cleaning needs of the bottom surface and low tables and chairs; the contamination concentration sensor is used to determine the concentration of contamination in the environment.

[0029] The adsorption module includes a vacuum adsorption unit and an electrostatic adsorption unit. The electrostatic adsorption unit adsorbs micron-sized short, fragmented SiC fibers using an adjustable high-voltage electric field of 3-8kV. The electrostatic adsorption unit includes a dust collection plate 17 coated with an anti-adhesion coating (silicon nitride coating) to reduce adhesion. The vacuum adsorption unit includes an adsorption port 16, which is a segmented silicone scraper adsorption port. The width of the adsorption port 16 is electrically adjustable within the range of 200-800mm to improve adaptability to complex surfaces and narrow areas. The adsorption port 16 is connected to a fan 20, which is a negative pressure variable frequency fan adjustable from 0.5-5.0kPa. The adsorption module also includes a high-voltage electrode 15, which is connected to the adjustment unit 4 and the power supply module 7 in the intelligent control system described below. Specifically, the pollutant concentration sensor 18 determines the pollutant concentration and feeds the result back to the adjustment unit 4. The adjustment unit 4 controls the high-voltage electrode 15 to start working (i.e., start the mixed adsorption mode), and at the same time, the adjustment unit 4 controls the power supply module 7 to supply power to the high-voltage electrode 15.

[0030] The multi-stage filtration and storage module includes a first filter 12 and a second filter 9 for intercepting large particulate impurities. The first filter 12 is a pre-filter, and the second filter 9 is a HEPA filter. The second filter 9 is connected to a cyclone separator 10, which is connected to a collection box with a volume of 10L. The inner wall of the collection box is coated with a polytetrafluoroethylene antistatic liner to reduce fiber adhesion. The collection box adopts a magnetic quick-release structure, with a full-load weight detection error of ≤±5%, facilitating quick replacement and cleaning. The collection box includes a first collection box 13, a second collection box 11, and a third collection box 8. The third collection box 8 is fitted outside the second collection box 11, and the second filter 9 is located on the inner wall of the second collection box 11. The cyclone separator 10 handles ≥800m / s... 2Centrifugal acceleration separates medium-sized particles, with the second filter achieving a filtration efficiency of 99.97% for PM0.3 particles. The multi-stage filtration and storage module also includes a differential pressure sensor, triggering a replacement reminder when the resistance exceeds 500Pa. The multi-stage filtration function of the multi-stage filtration and storage module effectively separates and collects short-fragmented SiC fibers from fine dust and large particulate impurities. The multi-stage filtration and storage module is sealed to the adsorption module to ensure no secondary dust generation, and meets Class II explosion-proof environmental protection requirements through an IP54 housing and intrinsically safe circuitry.

[0031] The intelligent control system includes an adjustment unit 4 and a rangefinder 14. The adjustment unit 4 adjusts the operating mode based on the values ​​from the pollution concentration sensor 18 in the autonomous mobile chassis. The rangefinder 14 is an infrared rangefinder. Using the pollution concentration sensor 18 and a built-in algorithm, it determines that the PM0.3 particle concentration is ≤0.5 mg / m³. 3 (mg / m³) and the weight concentration of short-fragmented SiC fibers ≤ 0.2 mg / m³ 3 The condition is "low pollution concentration", with PM0.3 particulate concentration ≥ 0.5 mg / m³. 3 Or the weight concentration of short-fragmented SiC fibers is ≥0.2 mg / m³. 3 The condition is "high pollution concentration". When the pollution concentration is high, a single vacuum adsorption mode is first used for initial cleaning. After cleaning, once the corresponding low pollution concentration standard is reached, a mixed adsorption mode is activated for deep cleaning. Under high pollution concentration conditions, if the low pollution concentration standard is still not reached after three single vacuum adsorption cleaning cycles in the designated work unit area, the mixed adsorption mode is automatically activated for deep cleaning. In mixed adsorption mode, the pollution concentration sensor 18, combined with the built-in algorithm, analyzes and determines that the PM0.3 particle concentration is ≤0.05mg / m³. 3 Furthermore, the weight concentration of short, fragmented SiC fibers is ≤0.05 mg / m³. 3 The cleaning task can proceed to the next work unit area once the cleaning target is met.

[0032] The intelligent control system also includes a power module 7, a processing system 5, and a wireless communication module 6. The power module 7 supplies power to the entire SiC short fiber automated adsorption collection device. The processing system 5 is a microCPU processing system. The wireless communication module 6 supports 5G / Wi-Fi dual-mode transmission, uploading equipment status, filter life, and collection volume to the central monitoring platform in real time. It marks work units that fail to meet cleaning standards and notifies operators to handle them separately, realizing industrial networking and accurate identification of area cleaning capabilities.

[0033] The SiC short fiber automated adsorption collection device complies with the IP54 protection standard, and the key circuits adopt an explosion-proof design to ensure safe operation in highly polluted and dusty environments, forming a technical solution that integrates efficient collection, intelligent control and safety protection.

[0034] The working process of an automated adsorption-type collection device for SiC short shreds is as follows: the autonomous moving chassis plans the cleaning path through the SLAM navigation module 19, the ultrasonic radar module 2 dynamically adjusts the cleaning route according to obstacles, the intelligent control system adjusts the mode of the adsorption module according to the pollution concentration, the adsorption module adsorbs the SiC short shreds, and the adsorbed SiC short shreds are stored in the multi-stage filtration and storage module.

[0035] The automated adsorption-type collection device for SiC short fiber fragments of this invention can be widely applied in production workshops of SiC fibers, ceramic matrix composites, and metal matrix composites, solving the problem of SiC short fiber fragment pollution. It is also suitable for dust cleaning needs in chemical, electronics, and other fields. With the increasing demands for cleanliness in high-end manufacturing environments, this technology is expected to become a standardized configuration for industrial cleaning equipment, promoting intelligent upgrades in workshops, reducing occupational health risks, and improving resource recycling rates, thus showing broad market prospects.

[0036] The present invention also discloses an automated adsorption-based collection method for SiC short fragments, based on the above-mentioned device, comprising the following steps: an autonomously moving chassis adjusts the adsorption height and adsorption position; an intelligent control system adjusts the mode of the adsorption module according to the pollution concentration; the adsorption module adsorbs the SiC short fragments; and the adsorbed SiC short fragments are stored in a multi-stage filtration and storage module.

[0037] The autonomous mobile chassis adjusts the adsorption height and position, including: a SLAM navigation module 19 planning the cleaning path, an ultrasonic radar module 2 dynamically adjusting the cleaning route based on obstacles, and a lifting mechanism 3 adjusting the adsorption height; the intelligent control system adjusts the adsorption module mode according to the pollution concentration, including: PM0.3 particle concentration ≥ 0.5 mg / m³. 3 Or the weight concentration of SiC short fragments is ≥0.2 mg / m³ 3 Initial cleaning is performed using vacuum adsorption mode. After cleaning, once the set standard of low pollution concentration is reached, deep cleaning is performed using mixed adsorption mode; PM0.3 particle concentration ≤ 0.5 mg / m³. 3 Furthermore, the weight concentration of SiC short fragments is ≤0.2 mg / m³. 3The process employs a hybrid adsorption mode combining vacuum and electrostatic adsorption. The adsorption module adsorbs short SiC fibers and stores the adsorbed short SiC fibers in a multi-stage filtration and storage module. This process includes: the adsorption module adsorbs the short SiC fibers; the adsorbed short SiC fibers are filtered through the first filter screen 12 and then centrifuged in the cyclone separator 10; the separated short SiC fibers are filtered through the second filter screen 9 and then stored in a collection box.

[0038] Example In a SiC / SiC composite material production workshop, after the automated adsorption collection device for short SiC fibers is activated, the autonomous mobile chassis automatically plans the cleaning path via the SLAM navigation module 19. The ultrasonic radar dynamically adjusts the route after detecting obstacles on the ground. Based on feedback from the infrared rangefinder 14, the adsorption module extends the adsorption port 16 to a width of 600mm and adjusts the support leg lifting mechanism from 3m to 0m in height, reaching deep into the bottom area of ​​the equipment. At this point, the pollution concentration sensor 18 detects that the density of the short SiC fibers exceeds the standard. The intelligent control system first uses a 4.0kPa single vacuum adsorption mode for preliminary cleaning, combined with the segmented silicone scraper adsorption port 16 for sweeping and adsorption. After the first preliminary cleaning is completed, the pollution concentration sensor 18 determines the PM0.3 particle concentration to be 0.45mg / m³. 3 Furthermore, the weight concentration of short, fragmented SiC fibers is 0.18 mg / m³. 3 Upon reaching a low pollution concentration standard, the system automatically switches to a mixed adsorption mode. The electrostatic unit applies a 6kV voltage to adsorb micron-sized fibers, while the vacuum unit uses a 5.0kPa negative pressure to absorb particulate pollutants. The collected fibers, after impurities are intercepted by the first filter 12, enter the cyclone separator 10 for centrifugal separation. Finally, the second filter 9 filters out fine dust, and clean air is discharged. The fibers are stored in a 10L anti-static collection box. When the filter resistance reaches 500Pa, the system triggers a replacement prompt. Workers can quickly replace the filter using a magnetic quick-release structure. The entire process is dust-free, and the residual rate of short, broken SiC fibers in the workshop is reduced to ≤0.05mg / m³. 2 .
