2results about How to "Reduce dust phenomenon" patented technology

The utility model discloses a kind of automatic packing equipment of coal powder, it is related to coal powder processing technical field, the utility model includes equipment main body, equipment main body inside is separately provided with feeding assembly, transfer assembly, powder loading assembly, hanger, upper cover assembly, gland assembly and discharging assembly;Transfer assembly includes electric turntable installed in the equipment main body inside below, photoelectric proximity switch installed in the equipment main body inside one side and four ultrasonic sensors installed in the hanger top.The utility model is equipped with powder loading assembly, upper cover assembly and gland assembly, in powder loading assembly, dust brush is attached to the top of coal powder barrel, can reduce dust raising phenomenon in powder loading process, reduce material loss and environmental impact;Weigher is attached to the bottom of coal powder barrel under lifting cylinder drive, through numerical zeroing to remove barrel body self-weight, real-time measurement is carried out to coal powder, can reduce the situation of uneven powder loading amount, guarantee the consistency of the weight of each coal powder;It is convenient for automatic filling, convenient operation.

The utility model relates to the technical field of building engineering, disclose a multifunctional earthmoving device for building engineering, including the frame, the top fixed coupling of frame has the water tank, the one end of frame swing installation has the fender, one side surface fixed coupling of fender has first shower nozzle, the top fixed coupling of first shower nozzle has the sleeve pipe, one side surface fixed coupling of water tank has the plug -in pipe. The utility model has the advantages and effects that: when the frame is walking, the lowering of the lifting frame makes the bulldozer bucket contact with the ground and push the earth, at this time, the clean water in the water tank enters the sleeve pipe from the plug -in pipe, and then enters the first shower nozzle, and fine mist is sprayed from the atomizing nozzle, the water pipe sends the clean water to the second shower nozzle, improves the water mist spraying range, and the fine water droplets are beneficial to drift, the moderate water volume can evaporate in a relatively short time after being sprayed, and the water mist is limited to inhibiting dust in the air, reducing the dust raising phenomenon, thereby facilitating the continuous construction of the working environment.
