Description

Technical Field

[0001] The utility model relates to the technical field of resource disposal of construction waste, in particular to a construction waste disposal system. Background Art

[0002] With the acceleration of urbanization and the rapid development of the construction industry, the amount of construction waste generated is increasing year by year. Construction waste primarily consists of concrete blocks, bricks, waste wood, waste plastics, waste metal, and other construction waste generated during the demolition of buildings. If this construction waste is not effectively handled, it will not only occupy a large amount of land resources but also cause serious environmental pollution.

[0003] Traditional methods of construction waste disposal mainly rely on manual sorting, landfilling or simple mechanical processing, followed by landfilling or incineration. This treatment method has the following major problems:

[0004] 1) Waste of resources: Landfilling and incineration of construction waste results in the waste of a large amount of renewable resources (such as metals, plastics, concrete, etc.), failing to achieve resource recycling. In particular, the waste of metal materials not only affects economic benefits but also increases the demand for mineral resources.

[0005] 2) Environmental pollution. Incineration of construction waste produces large amounts of harmful gases, increasing air pollution. Landfilling can cause harmful substances to seep into groundwater, contaminating soil and water sources. Furthermore, construction waste landfills occupy large areas and are difficult to reuse after landfill, further exacerbating land resource constraints.

[0006] 3) High costs for manual sorting. In traditional construction waste disposal methods, much of the waste sorting work requires manual operation, which is labor-intensive, inefficient, and has high labor costs. Furthermore, the limited accuracy of manual sorting can easily lead to waste of recyclable resources.

[0007] 4) Low processing efficiency. Traditional processing equipment and technologies are unable to effectively sort and process construction waste, especially when dealing with mixed waste. The sorting and crushing process is complex and time-consuming. Limited processing capacity makes it difficult to meet the huge amount of construction waste generated by modern urban construction.

[0008] Therefore, how to achieve efficient treatment of construction waste and resource recycling of construction waste is a technical problem that technicians in this field currently need to solve. Utility Model Content

[0009] The purpose of the utility model is to provide a construction waste disposal system for realizing efficient treatment of construction waste and resource recycling of construction waste.

[0010] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0011] A construction waste disposal system, comprising:

[0012] a screening mechanism comprising a rotating drum rotating along its own axis, wherein the rotating drum is provided with a screen having meshes, so that the screening mechanism screens particles of different sizes through the rotating drum;

[0013] The crushing mechanism includes a coarse crushing part and a fine crushing part.

[0043] The core of the utility model is to provide a construction waste disposal system for realizing efficient treatment of construction waste and resource recycling of construction waste.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the embodiment of the present invention discloses a construction waste disposal system, including a screening mechanism 100, a crushing mechanism 200, a sorting mechanism 300 and a recycling mechanism 400. The screening mechanism 100 is provided with a rotating drum 110, which can rotate around its own axis, and a screen is provided on the rotating drum 110, which has mesh holes. During the rotation and rolling of the rotating drum 110, particles with smaller diameters in the construction waste are separated from the mesh holes, and the waste is preliminarily classified, which is convenient for subsequent classification and special treatment of waste of different sizes. The larger diameter waste materials screened out in the screening mechanism 100 are continuously transported to the crushing mechanism 200, which is provided with a coarse crushing part 210 and a fine crushing part 220. The garbage material is crushed and processed in stages. The larger diameter garbage material is first transported to the coarse crushing part 210 through the feed port for preliminary crushing, reducing the overall size of the larger diameter garbage material to form preliminary crushed material. The preliminary crushed material is then transported to the fine crushing part 220 for further crushing to form fine crushed particles with a smaller diameter and reaching a preset diameter size. Finally, the fine crushed particles are transported out from the discharge port to enter the next processing link. The step-by-step crushing in the coarse crushing part 210 and the fine crushing part 220 ensures the uniformity of the size of the fine crushed particles, which is beneficial to subsequent sorting and resource recovery. The fine particles obtained by the crushing mechanism 200 are then transported to the sorting mechanism 300. The sorting mechanism 300 screens and separates the heavy particles, light particles, and metal particles from the fine particles, and classifies them for recycling as reusable resources. The separated heavy particles, light particles, and metal particles are then transported to the recycling mechanism 400. The balers in the recycling mechanism 400 compress and pack the heavy particles, light particles, and metal particles respectively. Compression can reduce the packaging volume, making it easier to transport and store. The classified packaging process also avoids mixing of different types of materials, making subsequent processing or reuse quick and convenient. The construction waste disposal system provided in this embodiment also adopts a closed design, which can effectively avoid pollution problems such as dust and noise, and avoid secondary pollution to the environment. In addition, the screening mechanism 100, crushing mechanism 200, sorting mechanism 300, and recycling mechanism 400 are independently designed functional units with a modular structure, which is convenient for modular configuration and expansion according to different needs. This allows the system configuration to be flexibly adjusted according to the actual situation of the construction waste to meet the needs of construction waste treatment of different scales and types.

[0045] In a specific embodiment, the rotating drum 110 is provided with an inlet and an outlet. After the construction waste enters the inner cavity of the rotating drum 110 through the inlet, the construction waste rolls in the rotating drum 110 and rolls from the inlet of the rotating drum 110 toward the outlet as the rotating drum 110 rotates around its own axis. Particles with smaller diameters are screened out through the mesh of the screen and collected for subsequent sorting, while particles with larger diameters are discharged from the outlet for collection and subsequent crushing processing.

[0046] Furthermore, the rotating drum 110 may be provided with a plurality of screens, and the aperture sizes of the meshes of different screens are different. Thus, in the process of preliminary screening of construction waste, the screens with meshes of different sizes are adjusted according to the different sizes of construction waste to meet the needs of screening more construction waste, thereby enhancing the adaptability of the construction waste disposal system provided by this embodiment.

[0047] In addition, the screening mechanism 100 provided in this embodiment is also provided with a monitoring unit. The detection unit monitors the construction waste screening process in the screening mechanism 100 in real time, ensuring that the screening mechanism 100 has good screening accuracy for the construction waste and promptly detecting problems that arise during the screening process, thereby improving the reliability and stability of the construction waste disposal system. In a specific embodiment, the monitoring unit uses a surveillance camera. The surveillance camera captures images of the construction waste being screened in real time, records the screening status of the waste, and feeds the captured images back to the construction waste disposal system provided in this embodiment for analysis and processing, thereby achieving high detection accuracy.

[0048] like Figure 4 As shown, the sorting mechanism 300 includes a gravity separator 310 and a magnetic separator 320. First, heavy particles (such as concrete blocks, metals, etc.) and light particles (such as plastics, wood, etc.) are separated by the gravity separator 310. After sorting by the gravity separator 310, the sorted particles are transported to the magnetic separator 320. The strong magnetic field of the magnetic separator 320 can extract particles containing magnetic metal components such as iron, and separate metals from non-metals, thereby effectively recovering metal materials and reducing waste.

[0049] like Figure 1 and Figure 6 As shown, the construction waste disposal system provided in this embodiment transports materials through a conveying mechanism equipped with a conveyor belt 500, and the conveyor belt 500 is used between the screening mechanism 100, the crushing mechanism 200, the sorting mechanism 300 and the recycling mechanism 400 to transport the materials to the next link, ensuring the efficient flow of material waste in the entire construction waste disposal system and improving the efficiency of waste treatment.

[0050] In order to further improve the automation performance of the construction waste disposal system provided in this embodiment, the conveying mechanism is also provided with a conveying control unit, which controls the conveying direction and conveying speed of the conveyor belt 500. Therefore, during the waste disposal process, the conveyor belt is adjusted according to actual conditions, thereby ensuring the smoothness and efficiency of the waste turnover and transportation process.

[0051] In one specific embodiment, the crushers of both the coarse crushing unit 210 and the fine crushing unit 220 of the crushing mechanism 200 are made of wear-resistant materials. Crusher made of wear-resistant materials are well suited for crushing hard materials such as concrete and metal blocks used in construction, significantly extending the service life of the crushing equipment. In one specific embodiment, the wear-resistant material can be high manganese steel, alloy steel, or cast steel, among others, which are not listed here.

[0052] In another specific embodiment, the construction waste disposal system provided in this embodiment also includes an automatic control unit. Through the matching of the automatic control unit and the monitoring unit, the automation capability of the construction waste disposal system is greatly improved. The crushing mechanism 200, the sorting mechanism 300 and the recycling mechanism 400 can automatically adjust the construction waste processing process according to the different characteristics of the garbage, thereby improving the fineness and accuracy of garbage processing, making the entire construction waste disposal system easy to operate and more intelligent, and only a small number of personnel are required to monitor the operation of the system, which greatly reduces labor costs.

[0053] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
