[0030] Embodiment 1 Implementation background: In the original conveying system of this coal preparation plant, due to large fluctuations in coal flow, traditional fixed baffles frequently overflowed, resulting in an average of 4 shutdowns for cleaning per month, with each cleaning time > 2 hours. The overflow caused about 3% coal loss and exceeded the dust pollution standard, posing a risk of environmental protection penalties.

[0031] Specific implementation: S1001: The conveyor belt 201 is made of wear-resistant rubber material, with a bandwidth of 1.2 m, driven by a drive motor 202. The speed controller 203 sets the conveying rate through a PLC. The blocking baffles 204 are equidistantly installed on the belt surface at a spacing of 0.8 m to effectively separate the material flow and prevent lateral accumulation; S1002: The anti-overflow baffle 301 is welded from Q235 steel plates, with a height of 50 cm, continuously arranged along both sides of the belt. The laser ranging sensor 305 is installed on the second mounting platform 304 to scan the material pile height at a frequency of 50 Hz. The data is processed by the data analyzer 303, and an early warning is triggered when the pile height exceeds the limit; S1003: The laser ranging unit A1001 is integrated with the existing sensor 305. The piezoelectric film of the pressure detection unit A1002 is embedded on the surface of the discharge control console 501 to monitor the impact load in real time. The speed monitoring unit A1003 monitors the belt speed through an encoder, and the data is sent to the decision-making module through a wireless transmission module; S1004: When the pile height exceeds the limit, the intelligent decision-making module A2002 calls the PID algorithm, and controls the first rotation motor 404 through the servo drive unit A3001 to drive the push rod 407 to perform 3 reciprocating swings, pushing the material to the center of the conveyor belt. The pneumatic muscle of the flexible adjustment unit A3002 synchronously adjusts the inclination angle of the anti-overflow baffle 301 to optimize the material flow trajectory; S1005: The air compressor 505 forms a negative pressure area at the discharge port, which cooperates with the coal powder brush 602 to clean the belt surface. The collection box 604 is regularly cleaned through the fixing bolts 605. In case of sudden overflow, the electromagnetic clutch of the emergency execution unit A3003 immediately cuts off the power of the drive motor 202, and the explosion-proof cylinder pushes the physical isolation baffle to close the discharge port; S1006: The support bracket 701 is welded with H-shaped steel. The support bottom plate 702 is fixed by 8 groups of M24 bolts. The moving wheels 704 are equipped with electric lifting devices, which are convenient for the whole equipment to be moved out of the operation line during equipment maintenance.

[0032] Implementation effect: After the device is put into operation, the overflow accident rate of the belt conveyor decreases by 82%, the dust emission concentration decreases by 65%, the conveying efficiency increases by 18%, the intelligent monitoring system achieves a fault warning accuracy rate of over 95%, and the equipment maintenance cost decreases by 30%, providing a reliable guarantee for the continuous production of the coal preparation plant.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
