Description

Technical Field

[0001] This utility model relates to the field of dust conveying technology, and in particular to a pneumatic auger unloading machine. Background Technology

[0002] Current unloading technologies still face numerous inconveniences: Dust sources are numerous in operations such as blasting, drilling, transportation, loading, crushing, screening, and belt conveying, and dust is easily dispersed due to factors such as air shear and material drop, making control difficult. Traditional unloading technologies lack effective dust capture and purification methods, easily leading to dust pollution of the working environment, affecting equipment efficiency and personnel health. Furthermore, unloading equipment, such as rotary valves, requires regular inspection, cleaning, lubrication, and replacement of wear parts, making maintenance cumbersome and costly. Equipment failure rates are high, with frequent problems such as valve jamming, air leakage, and material blockage affecting unloading efficiency and production continuity. In addition, dust and harmful gases generated during unloading operations, if not effectively controlled, will pollute the environment and may cause respiratory illnesses and other health problems for operators.

[0003] Therefore, material waste is common in mechanical engineering construction, including human waste (such as using the wrong material or cutting the wrong material) and normal waste (such as scrap materials and design allowances), which increases production costs.

[0004] In summary, existing unloading technologies still have many inconveniences in terms of dust control, equipment maintenance and efficiency, environmental and health risks, and resource waste, and urgently need to be improved through technological innovation and upgrading. Utility Model Content

[0005] The purpose of this utility model is to provide a pneumatic auger unloading machine to solve the problems in the background technology mentioned above.

[0023] As per the instruction manual Figure 1 As shown, this utility model discloses a pneumatic auger unloading machine, including a crusher 3, a dust collection pipe 5, a bag filter 8, and a conveying device.

[0024] The crusher 3 is located below the discharge port 1, which is equipped with a bag-breaking device 2 to facilitate the direct collection of dusty raw materials from the packaging, eliminating the loss and pollution during handling. The dusty raw materials entering from the discharge port 1 enter the crusher 3, where large pieces of material are crushed into small particles of the required size by mechanical force.

[0025] The crusher 3 has a dust suction pipe 5 and louvers 4 at its feed inlet. The dust suction pipe 5 draws light dust into the bag filter 8, while heavier metal particles or other heavy particles settle and are discharged through the louvers 4. Several airflow distribution plates 6 are installed at the connection between the dust suction pipe 5 and the bag filter 8. These plates optimize airflow distribution, guide the flow direction of the gas-liquid mixture, reduce airflow resistance in the pipe, and make the airflow distribution more uniform. This avoids energy loss caused by excessively high or low local flow velocities, reduces the impact of large particles on the subsequent bag filter 8, and extends the filter bag life. Simultaneously, they prevent dust from accumulating in dead corners of the pipe, reducing the risk of blockage and minimizing energy loss due to eddies.

[0026] The baghouse dust collector (8) includes a settling chamber (7), a back-blowing device, and a clean air conveying device. The settling chamber (7) contains several filter bags (8) for adsorbing dust. These bags are positioned below the back-blowing device, with their top openings connected to the clean air conveying device. The clean air conveying device includes a clean air duct (12), a centrifugal fan (13), and a chimney (14). The chimney (14) is connected to the outside, and the centrifugal fan (13) is positioned between the clean air duct (12) and the chimney (14). In the baghouse dust collector (8), the dust-laden gas first passes through the filter bags (8), whereby the dust is effectively filtered and trapped on the surface of the bags. Clean air then rises through the tiny gaps in the bags (8) and enters the clean air duct (12) of the clean air conveying device. During this process, the baghouse dust collector (8) plays a crucial filtration role, ensuring the quality of the air entering the clean air duct (12).

[0027] Centrifugal fan 13, as the core power unit of the clean air conveying system, accelerates the gas through its high-speed rotating impeller, generating sufficient pressure to continuously propel the clean air forward along the pipeline. Centrifugal fan 13 provides the power required for conveying. Finally, the clean air, under the action of centrifugal fan 13, is discharged into the atmosphere through chimney 14.

[0028] The back-flushing device includes a compressed air conveyor 9, a compressed air delivery pipe 10, and a nozzle 11. The compressed air conveyor 9 is located outside the bag filter 8 and is connected to the nozzle 11 via the compressed air delivery pipe 10. The back-flushing device uses compressed air as a power source to inject high-pressure air into the interior of the bag filter 8 in a pulsed manner. When the dust material intercepted on the outside of the bag filter 8 reaches a certain thickness, the back-flushing device will activate and spray compressed air. This high-pressure air enters the interior of the bag filter 8 through the nozzle 11, forming a reverse airflow that causes the bag filter 8 to expand and vibrate, thereby shaking off the dust from the outer layer of the bag filter 8. This fallen dust then enters the settling chamber 7 below.

[0029] The conveying device includes a first auger conveyor 15 and a second auger conveyor 17. The first auger conveyor 15 is installed inside the bag filter 8 dust collector. An automatic ash discharge valve 16 is installed at the connection between the first auger conveyor 15 and the second auger conveyor 17 to prevent material backflow. The dust material falling from the settling chamber 7 is collected in the first auger conveyor 15. The automatic ash discharge valve 16 continuously discharges the dust material into the second auger conveyor 17. The spiral blades of the second auger conveyor 17 are only partially installed and do not extend to its outlet. The tail end of the spiral blades is 500cm away from the outlet. The dust material slowly accumulates to form a cylindrical block, which is discharged to the outside during the continuous accumulation process.

[0030] Therefore, the wind-driven auger unloading machine of this utility model with the above-mentioned structure solves the problems of dust diffusion and pollution of the working environment and material waste in the existing dust unloading process. Through the efficient filtration mechanism of air separation and bag dust collector, it effectively captures dust generated by air shearing, material movement-induced dust formation, mechanical impact crushing and secondary dust generation, which not only significantly improves the working environment, but also protects the health of operators.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
