[0020] In this embodiment, the first processing box 10 is made of high-strength stainless steel and is bolted to the equipment base. It has an openable inspection door on top for easy internal maintenance. The inlet is located on the side wall of the box and connects to the feeding conveyor belt, with a sealing rubber ring preventing dust leakage. The circulation component 20 is a ring-shaped mesh belt structure, driven by a motor via a chain, allowing for stepless speed regulation. The mesh belt surface has anti-slip protrusions to ensure smooth transport of bamboo fiber during pretreatment. The pretreatment component 30 is fixed to the top and side wall of the first processing space by brackets, maintaining a 5-10cm distance from the circulation component 20 to allow for comprehensive processing of the bamboo fiber on the mesh belt. The second processing box 40 is connected to the first processing box 10 via a sealing partition and has shock-absorbing pads at the bottom to reduce vibration transmission during the crushing process. The output port uses a pneumatic sealing valve to control the finished product discharge. The crushing component is bolted to the second processing space and is sealed to the transport component 50 via a flange. The transport component 50 passes through the partition of the first and second processing boxes 40 and is fixed to the side wall of the box by bearing seats. Its two ends are respectively connected to the discharge end of the circulation component 20 and the feed inlet of the crushing component to realize the closed transport of materials.

[0021] Furthermore, the pretreatment component 30 includes: a spray unit having a cleaning section and a processing section, the spray unit being arranged opposite to the circulation component 20; and a drying unit disposed within the first processing space.

[0022] In this embodiment, the cleaning section of the spray unit consists of three sets of high-pressure nozzles, arranged in a triangle at the top of the first processing space. The nozzle angles are adjustable, and they are connected to a centrifugal pump in the first water tank via pipes to achieve high-pressure circulating water washing. The first water tank contains a filter screen and a sedimentation zone, and the filtered water is pumped back to the nozzles. The modifier nozzle in the processing section adopts a fan-shaped spray structure and is installed on a transverse slide rail in the middle of the first processing space. It can be moved left and right by an electric push rod to ensure that the bamboo fiber is evenly liquidated. The metering pump is a high-precision gear pump, which automatically adjusts the modifier flow rate according to the bamboo fiber conveying speed. The second water tank is used to store the diluted modifier solution, and the replenishment is controlled by a liquid level sensor. The drying unit is a hot air circulation structure, installed at the tail of the first processing space, and consists of an electric heating tube and an axial flow fan. Hot air is evenly blown onto the mesh belt through a perforated plate to dry the bamboo fiber, and the hot and humid air is discharged through the top exhaust port.

[0023] Furthermore, the crushing assembly includes: a first crushing unit 41, which is disposed in the second processing space and connected to the output end of the transport assembly 50; and a grading and screening unit 42, which is installed at the discharge port of the first crushing unit 41 and connected to the first crushing unit 41.

The equipment has built-in supersonic nozzles and classifying wheels. High-pressure airflow accelerates the bamboo fibers through the nozzles, causing them to collide and crush. The classifying wheels are driven by a variable frequency motor, and the speed can be adjusted to control the crushed particle size. The grading and screening unit 42 is a combination structure of a cyclone separator and a vibrating screen, installed below the first crushing unit 41 and connected by a pipe. After the cyclone separator separates the coarse particles, they are returned to the first crushing unit 41 through the return pipe, while the fine particles fall into the vibrating screen for secondary screening. Unqualified materials are also returned for crushing.

[0025] Furthermore, the crushing assembly also includes: a second crushing unit 43, which is located in the second processing space and connected to the discharge end of the grading and screening unit 42; and a finished product collection unit 44, which is located in the second processing space and connected to the discharge port of the second crushing unit 43, i.e. the chemical-assisted crushing unit. The finished product collection unit 44 collects the finished product and outputs it through the output port.

[0026] In this embodiment, the second grinding unit 43 adopts a structure combining ball milling and chemical assistance. The ball mill jar is filled with zirconium oxide grinding balls, and the side wall of the jar is provided with chemical reagent injection holes. The catalyst solution is atomized and sprayed in through a metering pump. The ball mill jar is driven by planetary gears to achieve three-dimensional grinding motion, further refining the bamboo fiber to the nanoscale. The finished product collection unit 44 is a vacuum collection bin, installed at the bottom of the second processing space, and connected to the discharge port of the second grinding unit 43 through a pipe. The collection bin has a built-in pulse backflushing device to prevent nanofibers from adsorbing onto the bin wall. The finished product is discharged from the equipment through the output port via a rotary discharge valve at the bottom.

[0027] Furthermore, the transport component 50 is a sealed tube chain conveyor, one end of which is connected to the discharge end of the circulation component 20, and the other end is connected to the feed inlet of the first crushing unit 41.

The pipe is connected to the partitions of the first and second processing boxes 40 via flanges, and a rubber sealing ring is provided at the connection. The chain disc is made of stainless steel and conveys the bamboo fiber output from the circulation component 20 to the first crushing unit 41 along the pipe through chain drive. The drive motor is equipped with a frequency converter, which can automatically adjust the conveying speed according to the working status of the pretreatment and crushing units to avoid material accumulation.

[0029] Furthermore, the cleaning unit includes: multiple sets of high-pressure nozzles, evenly distributed at the top of the first processing space and arranged opposite to the circulation component 20, for washing and cleaning the bamboo fiber; and a first water tank, located at the bottom of the first processing space and connected to the high-pressure nozzles through a pipe, for recycling and filtering the cleaning water for reuse. In this embodiment, the high-pressure nozzle adopts a quick-release design, which is convenient for disassembly and cleaning of blockages; the nozzle spacing is 20cm, and the spray angle is tilted downward at 30° to ensure that the water flow covers the entire mesh belt; the first water tank is divided into a sedimentation zone, a filtration zone and a clear water zone. The sedimentation zone separates impurities through inclined plate sedimentation, the filtration zone is equipped with an activated carbon filter element, and the centrifugal pump in the clear water zone delivers the treated water to the nozzle to form a circulating cleaning system.

[0030] Furthermore, the processing unit includes: a modifier nozzle, located in the middle of the first processing space and arranged opposite to the circulation component 20; a metering pump, installed on the pipeline between the modifier nozzle and the modifier storage tank, for precisely controlling the spray volume of the modifier; and a second water tank, located at the bottom of the first processing space and connected to the modifier nozzle via a pipeline.

[0031] In this embodiment, the modifier nozzle is equipped with a pressure sensor to monitor the spray pressure in real time; a drip tray is provided below the nozzle to prevent excess modifier from dripping and contaminating the equipment; the metering pump is linked to the speed sensor of the circulation component 20 through the PLC control system to automatically adjust the modifier flow rate according to the bamboo fiber delivery volume; the second water tank is equipped with a stirrer to ensure that the modifier solution is mixed evenly, and its liquid level is controlled by a float valve to achieve automatic liquid replenishment.

[0032] In summary, this utility model, through the integrated design of the dual-box separation and sealed transport component 50, achieves continuous and closed-loop production of bamboo fiber from pretreatment to crushing, effectively avoiding pollution and loss during material transfer; through the coordinated operation of the annular circulation component 20 and the multi-functional spray unit, it achieves efficient connection of pretreatment processes such as cleaning, modification, and drying; and through the graded treatment structure of mechanical crushing and chemical assistance, it achieves precise control of bamboo fiber nano-sizing, significantly improving the processing efficiency of the equipment and the quality of the finished product.
