Description

Technical Field

[0001] The invention relates to the technical field of construction waste treatment, in particular to an environmentally friendly construction waste treatment device. Background Art

[0002] The treatment and recycling of construction waste is a complex process involving a large amount of material sorting, crushing, separation and recycling. At present, common construction waste treatment methods mainly include mechanical crushing, physical sorting and chemical treatment. However, the existing technology has some significant defects in the treatment process, especially in dust treatment. At present, most construction waste treatment devices mainly rely on simple mechanical crushing and screening equipment for material separation. Although these devices can effectively handle large pieces of waste and achieve preliminary material classification, many existing construction waste treatment devices are not designed to take dust treatment into consideration, resulting in a large amount of dust generated during the crushing and sorting process. These dusts not only pollute the environment, but also harm the health of operators. Lacking special dust collection and filtration devices, the dust generated during the crushing and sorting process is often directly discharged into the air, causing serious air pollution.

[0003] Some existing construction waste treatment devices are equipped with dust treatment equipment, but their design and technical means are often relatively simple, mainly filtering through filter structures, and cannot effectively capture and filter tiny dust particles. Existing dust treatment devices usually use simple filter screens or dust removal bags. These devices have limited filtering effects on fine dust, are prone to clogging and difficult to maintain. During operation, dust treatment equipment often has the problem of reduced efficiency. Especially when processing large amounts of materials, dust easily accumulates and clogs on the surface of the filter structure, affecting its normal operation and treatment effect. Due to the lack of an efficient dust recovery mechanism, it is difficult to recycle and reuse the dust generated during the crushing process in the existing technology. This not only wastes resources, but also increases processing costs.

The ferromagnetic materials in the crushed materials pass through the discharge cylinder 101 and are discharged through the conveying fan unit 200 and the separation component 300 under the suction action of the conveying fan unit 200 under negative pressure.

[0048] Driven by the motor base 220, the centrifugal impeller 230 rotates at a high speed to introduce the airflow and powder through the flow collecting bucket 211 and centrifugally pump them through the guide vanes 240 to the inside of the guide tube 310. The gas and powder are guided by the guide vanes 321 and the swirl guide grooves 323 on the surface of the swirl core tube 320 to produce a swirl effect, thereby producing a centrifugal effect on the mass in the powder, so that the gas and powder are respectively discharged along the inner and outer sides of the separation guide ring 322, and the powder discharged along the outer periphery of the separation guide ring 322 is introduced into the internal structure of the dust guide ring seat 330 and gathered and discharged, while the gas is discharged through the airflow guide holes 324 and discharged after being filtered by the filter group 340 structure, thereby achieving gas purification and avoiding adverse effects on the surrounding environment.
