[0002] With the rapid urbanization and industrialization in my country, construction projects are accelerating, resulting in an alarming increase in construction waste. Currently, traditional disposal methods primarily involve landfilling and stockpiling. In economically developed regions, construction waste processing lines exist because these facilities typically require large spaces for operation and processing. This can limit the selection of installation sites, especially in urban or densely populated areas where finding suitable locations can be more difficult. Furthermore, the large land area required increases land use costs, a significant burden for many processing companies. The high cost of construction waste processing equipment includes purchase, installation, and subsequent maintenance. This equipment often requires specialized technical support and complex operating procedures; therefore, in addition to the equipment cost itself, training costs for relevant personnel must also be considered. Moreover, the long investment return cycle of such equipment can lead to significant financial pressure for companies in the short term.

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 6 As shown, a frame-type disposal line for construction demolition waste includes a frame 1, a grading device 2, an air separation device 3, a sorting device 4, and a storage device 5 arranged sequentially along the waste conveying direction.

[0029] The grading device 2 includes a feeder 21 for receiving construction demolition waste and a screening machine 22 connected to the feeder 21 for screening the construction demolition waste.

The screening machine 22 is a heavy-duty tension screening machine, with a 3D stepped screening module on the upper layer and a polyurethane tension screening module on the lower layer. The feeder 21 is a variable frequency feeder. Specifically, the feeder 21 is inclined upward along the conveying direction of the construction demolition waste, and the screening machine 22 is inclined downward along the conveying direction of the construction demolition waste. Furthermore, before the construction demolition waste enters the feeder 21, it is necessary to manually remove oversized materials ≥500mm to prevent oversized materials from affecting the normal operation of the equipment.

[0030] The air classifier 3 includes a base frame 31, a first belt conveyor 32 and a second belt conveyor 33 arranged vertically on the base frame 31, a first air classifier 34 and a second air classifier 35 respectively opposite to the first belt conveyor 32 and the second belt conveyor 33, a first mounting frame 36 mounted on the base frame 31 for mounting the first belt conveyor 32, a second mounting frame 37 for mounting the second belt conveyor 33, and a feed hopper 38 mounted on the second mounting frame 37 for feeding material to the second belt conveyor 33. The first mounting frame 36 is supported on the second mounting frame 37, and the feed hopper 38 is connected to the second belt conveyor... The feed ends of the machines 33 are opposite each other; specifically, the first belt conveyor 32 and the second belt conveyor 33 are arranged in the same direction, the air outlet direction of the first air classifier 34 is opposite to the conveying direction of the first belt conveyor 32, and the air outlet of the second air classifier 35 is opposite to the conveying direction of the second belt conveyor 33, so that the light materials in the coarse aggregate and the light materials in the fine aggregate can enter the same bin for recycling; furthermore, the length of the first belt conveyor 32 is longer than the length of the second belt conveyor 33, and the second belt conveyor 33 is equipped with an iron remover, which can effectively remove old metals from the fine aggregate.

The first air outlet 344 is opposite to the coarse aggregate falling downward from the discharge end of the first belt conveyor 32, so that the air blown out from the first air outlet 344 can blow out the light materials in the coarse aggregate. Specifically, the first air outlet 343 includes a first air intake section 345 connected to the first fan 342 and extending along the coarse aggregate conveying direction, and a first air outlet section 346 connected to the first air intake section 345 and bending downward. The first air outlet 344 is located at the end of the first air outlet section 346, on the side below the discharge end of the first belt conveyor 32, opposite to the coarse aggregate falling downward from the discharge end of the first belt conveyor 32.

The two second air outlet pipes 354 are respectively located on both sides of the second belt conveyor 33, and the second air outlets 355 are connected to the lower side of the second belt conveyor 33. The fine aggregate falling downwards from the discharge end of the belt conveyor 33 is aligned with the fine aggregate to remove light materials. Through the cooperation of the air outlet 353 and the two second air outlet pipes 354, it is ensured that the air outlet of the second belt conveyor 33 is uniformly vented, thus ensuring the air separation effect of the fine materials. Specifically, the free end of the second air outlet pipe 354 extends downwards to the bottom of the second belt conveyor 33 to be aligned with the fine aggregate falling downwards from the discharge end of the second belt conveyor 33. Furthermore, the first air separator 34 and the second air separator 35 can adjust the blowing angle and air volume according to the characteristics of the incoming raw materials.

Specifically, the sorting table 41 is equipped with 10-12 sorting stations, each sorting the impurities in the aggregate according to their various properties. The sorting belt conveyor 42 is a frequency conversion sorting belt conveyor, which can be adjusted according to the on-duty status of the sorting station personnel or the conveying volume. It is equipped with a pull-wire switch on top, and the reasonable human-machine size allows for easier and faster emergency stop braking in case of emergency. The first iron remover 44 can effectively remove old metal from the sorted coarse aggregate to obtain inorganic coarse aggregate.

[0034] The storage device 5 includes a first storage bin 51 located below the screening machine 22 for storing slag, a second storage bin 52 spaced along the waste conveying direction below the second belt conveyor 33 for storing fine aggregates of 10-40mm, a third storage bin 53 for storing lightweight materials, and a fourth storage bin 54 located between the first storage bin 51 and the second storage bin 52 for storing scrap metal. The discharge end of the second belt conveyor 33 is vertically opposite to the second storage bin 52, so that the fine aggregates after removing lightweight materials fall downwards into the second storage bin 52 for storage. Specifically, the base frame 31 is provided with a first discharge port 311 opposite to the discharge end of the second belt conveyor 33 and a second discharge port 312 opposite to the third storage bin 53. The first discharge port 311 guides the fine aggregates into the second storage bin 52, and the second discharge port 312 guides the lightweight materials into the third storage bin 53.

[0035] This application defines a modular and integrated construction demolition waste disposal line, integrating a grading device 2, an air separation device 3, a sorting device 4, and a storage device 5 into one unit. Each device can be used independently. When in use, the required devices can be transported to the processing site according to site requirements and then assembled, effectively saving equipment installation time and floor space, and greatly reducing investment costs. In addition, the disposal line defined in this application can recycle construction demolition waste to obtain 0-10mm slag, 10-40mm fine aggregate, and 40-500mm coarse aggregate, preventing resource accumulation and waste.
