Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides an air curtain barrier type construction waste sorting and dust removal device. Its basic components mainly include a sorting box 100. In order to extract the residual value of construction waste, it is usually crushed and sorted before processing. The processing scope mainly includes demolished brick walls, tiles, concrete and other brick-concrete structure waste. It mainly uses a crusher to crush it into aggregate, which is suitable for recycled bricks, blocks and wall materials. The screen in the crusher is used to classify it into coarse and fine aggregates to ensure the efficient recycling of construction waste. For the sorting and processing of construction waste, the waste usually needs to be piled up in a specific location, and then fed into the sorting machine with the help of a loader or excavator. Then, the material is initially sorted by sorting equipment, such as a vibrating screen, a ring flat steel ring screen machine or an air classifier. The sorted material is then transported to the feeding structure 200 by a conveyor belt, and then enters the sorting box 100 for secondary dust removal to prevent dust in the material from spreading into the air with the conveyor belt outlet.

[0019] Example: Reference Figures 1-4A conveyor belt, or conveyor structure 300, is installed inside the sorting box 100. Driven by a motor, the bearing surface is formed on the surface of the conveyor belt. The output end of the feeding structure 200 faces the bearing surface of the conveyor structure 300 so that the pre-sorted material can be smoothly conveyed into the sorting box 100. A partition is installed on the inner wall of the sorting box 100 so that the material can fall onto the conveyor belt, which can ensure the stability of the material during the conveying process and prevent the material from scattering or accumulating at the bottom of the sorting box 100 during the conveying process.

[0020] Furthermore, the sidewall of the conveyor belt can be moved to fit against the sidewall of the sorting box 100 to further ensure the stability of the material on the conveyor belt. The drive motor of the conveyor belt is installed on the outer wall of the sorting box 100 and is connected to the main shaft of the conveyor belt through a reducer and a chain to realize the transmission of power. At the end of the conveyor belt, which is inclined, the material is conveyed from low to high. The sorting box 100 is provided with an outlet, namely the discharge channel 101, and a shielding curtain 102 is provided on the discharge channel 101. The feeding structure 200 is located at the other end of the sorting box 100 so that the sorted and dust-removed material can be smoothly discharged from the sorting box 100.

[0021] Specifically, to prevent dust from being generated during material conveying, an air curtain barrier structure 500 is installed above the conveyor belt. This structure mainly includes an air curtain machine 501 installed at the top of the sorting box 100. The air curtain machine 501 is connected to the blower 401 through a pipe. A guide plate 502 is installed on the side wall of the sorting box 100. The output end of the air curtain machine 501 faces the guide plate 502. The air curtain machine 501 can generate airflow to form an air curtain, which effectively blocks the dust generated during the material conveying to the outside of the discharge channel 101, preventing it from spreading into the air, thereby achieving the effect of dust removal.

[0022] A fan 401, also known as a dust removal structure 400, is installed on the sorting box 100. A filter plate 402 is installed inside the sorting box 100, and the filter plate 402 is located below the feeding structure 200. The air outlet of the fan 401 faces the surface of the filter plate 402. When the material enters the sorting box 100 through the feeding structure 200, it will first be guided by the filter plate 402 and then fall onto the conveyor belt. During this falling process, the dust in the material will be removed, and the dust mixed in with it will be separated.

[0023] Furthermore, the air curtain machine 501 is connected to the pipe fan 401. It should be explained that the wind speed of the air curtain machine 501 is greater than the wind speed of the fan 401 entering the sorting box 100, forming an airflow isolation barrier. This ensures that the airflow generated by the air curtain machine 501 can block the dust entering the discharge channel 101. The output end of the fan 401 is equipped with a conveyor box, and the pipe on the air curtain machine 501 is connected to the conveyor box. The conveyor box is equipped with a speed regulating valve that can adjust the airflow rate. By adjusting the speed regulating valve, the airflow rate in the pipe can be controlled, thereby adjusting the wind speed generated by the air curtain machine 501.

[0024] In addition, the filter plate 402 can not only perform preliminary dust removal on the materials entering the sorting box 100 and reduce the amount of dust, but also the filter plate 402 is detachably connected to the sorting box 100, making it easy to disassemble and clean, and convenient for users to maintain regularly.

[0025] A negative pressure adsorption structure 600 is provided on the sorting box 100. The adsorption end of the negative pressure adsorption structure 600 is connected to the cavity of the sorting box 100. A first adsorption tube 601 is provided on the top of the sorting box 100 and is connected to it. A second adsorption tube 602 is provided on the top of the discharge channel 101 and is connected to it. The first adsorption tube 601 and the second adsorption tube 602 are combined to form the negative pressure adsorption structure 600. The first adsorption tube 601 and the second adsorption tube 602 are connected to a negative pressure source, which can be a bag filter or a... The dust collector uses a negative pressure source to perform negative pressure adsorption on the inside of the sorting box 100 through the first adsorption tube 601, effectively removing dust generated during the sorting process and keeping the inside of the sorting box 100 clean. At the same time, the second adsorption tube 602 performs negative pressure adsorption on the discharge channel 101 to prevent dust from escaping from the discharge channel 101, further improving the dust removal effect. This negative pressure adsorption design enables the entire device to effectively control dust during operation and prevent dust in the material from spreading into the air through the conveyor belt discharge channel 101.

[0026] Specifically, when the dust removal structure 400 and the air curtain barrier structure 500 are working, the negative pressure adsorption structure 600 continues to work, performing negative pressure adsorption inside the sorting box 100 to keep the air inside the sorting box 100 clean and separate the dust from the sorted construction waste. At the same time, the air curtain barrier structure 500 forms a barrier at the discharge port of the sorting box 100, using high-speed airflow to prevent dust from spreading to the outside, further enhancing the dust removal effect. These three structures work together to form a highly efficient and environmentally friendly construction waste sorting and dust removal device, providing strong technical support for the treatment and reuse of construction waste.

[0027] Components not described in detail in this article are existing technologies.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
