AI Technical Summary
The dust removal devices of existing concrete spraying machines have complex structures, and it is time-consuming and labor-intensive to replace vulnerable parts. Dust above the hopper cannot be collected, resulting in low dust removal efficiency and high equipment costs. Poor sealing leads to dust leakage and poor dust removal effect.
The fully enclosed hopper structure and ultra-atomizing rotary nozzles generate a saturated water mist curtain inside the hopper to suppress dust. Combined with the ultra-atomizing rotary nozzles and the uniform dispersion of water mist, it ensures that the mixture does not generate dust in the enclosed space, and the dust above the hopper is also effectively suppressed.
This system enables enclosed dust control within the hopper, improving dust removal efficiency, reducing equipment disassembly and assembly time, lowering procurement costs, and ensuring construction progress and project quality.

[0022] (III) Beneficial Effects
[0023] This utility model provides a super-atomizing humidifying and dust-removing concrete spraying machine, which has the following beneficial effects:
[0024] 1. This ultra-atomizing humidifying dust removal concrete spraying machine, using the equipment of this patented technology, adopts a fully enclosed structure for the feeding system and hopper. The dust generated during feeding can be contained in a sealed space and will not overflow, eliminating the need for a separate dust collection device. An ultra-atomizing rotating nozzle is installed above the hopper, and when connected to a water source, it can generate a saturated ultra-atomized water curtain in the hopper to quickly suppress the dust generated during feeding.
[0025] 2. This ultra-atomizing humidifying and dust-removing concrete spraying machine, within a sealed chamber, allows the water mist generated by the ultra-atomizing rotating nozzle to be evenly dispersed into the spraying mixture. The fine water droplets and dust particles from the dust mix fully combine and adhere to the aggregate in the mixture, keeping it moist. This effectively prevents dust generation when the mixture passes through the rotor conveyor mechanism and allows for proper control of the water intake. Because the water mist generated by the ultra-atomizing rotating nozzle is sufficiently uniform, the mixture remains loose in the hopper, preventing the formation of large wet lumps. This does not affect the material feeding speed or the smoothness of the spraying, ensuring construction progress and project quality. Attached Figure Description
