Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a high-efficiency device for sorting construction waste. Background Technology

[0002] It is a high-efficiency equipment designed for the classification of construction waste. Through mechanical sorting, crushing and screening, it can quickly classify and recycle construction waste. During operation, construction waste is fed into the equipment through the feeding system. First, the sorting module separates recyclable materials such as metal and wood. Then, the crushing device crushes concrete, bricks and other materials to the specified particle size, reducing landfill pollution and resource waste. It is widely used in building demolition sites, construction waste treatment plants and other scenarios, providing technical support for green building and circular economy.

[0003] Construction waste is fed into the equipment via a conveyor belt. First, it passes through a magnetic separator to separate magnetic materials such as ferrous metals. Non-magnetic materials enter the crushing device and are crushed into particles of different sizes. Then, the screening equipment classifies them by size. A wind or airflow system intervenes to further separate lightweight materials such as wood and plastics from heavy aggregates in the crushed material. The control system coordinates the operation of each module, monitors sorting efficiency and equipment status in real time, and ensures a smooth process. Finally, the metal, aggregates, lightweight materials and other components are discharged from different outlets, completing the preparation for classification, recycling and reuse.

[0004] In existing technologies, some construction waste sorting and processing equipment suffers from problems such as low sorting efficiency and complex operation. For example, some equipment struggles to accurately distinguish between different materials and types of construction waste, and the high degree of manual intervention leads to increased sorting costs and low efficiency, failing to meet the demand for rapid sorting and processing of large quantities of construction waste. Therefore, this paper proposes a high-efficiency device for construction waste sorting to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency device for sorting construction waste, aiming to improve the problem of low sorting efficiency in the existing technology.

[0006] The system includes a first load-bearing plate, which has an internal movable groove. A fixed jaw plate is fixedly connected to the top front side of the first load-bearing plate. A movable jaw plate is slidably connected inside the first load-bearing plate. An eccentric shaft is fixedly connected inside the movable jaw plate. A pulley is rotatably connected to the outside of the eccentric shaft. Two drive shafts are rotatably connected to the bottom of the movable jaw plate on opposite sides. A second load-bearing plate is fixedly connected to the bottom left side of the first load-bearing plate. A wind tunnel plate is fixedly connected to the bottom of the second load-bearing plate. An impact crusher is fixedly connected to the right side of the wind tunnel plate. A third load-bearing plate is fixedly connected to the top of the impact crusher. A powered tearing arm is fixedly connected to the top of the third load-bearing plate. The wind tunnel plate has a waste sorting component.

[0007] As a further description of the above technical solution:

[0008] The sorting component includes a duct, with multiple air nozzles fixedly connected to the top of the duct, a second fan fixedly connected to the right side of the duct, a fixed plate fixedly connected to the left side of the duct, a fourth load-bearing plate fixedly connected to the top of the fixed plate, a cover plate fixedly connected to the rear side of the fourth load-bearing plate, a discharge plate fixedly connected to the bottom of the cover plate, and a sorting groove opened on the top of the discharge plate.

[0009] As a further description of the above technical solution:

[0010] The top of the wind tunnel plate is fixedly connected to a load-bearing column, the right side of the load-bearing column is rotatably connected to an impact crusher, the right side of the impact crusher is rotatably connected to a load-bearing bearing column, and the inside of the load-bearing bearing column is rotatably connected to a transmission shaft.

[0011] As a further description of the above technical solution:

[0012] The pulley is fitted with a transmission belt, the two drive shafts are fitted with transmission belts, and the front of the load-bearing plate is fitted with a conveyor belt.

[0013] As a further description of the above technical solution:

[0014] An air inlet is fixedly connected inside the wind tunnel plate, a fan is fixedly connected to the front side of the wind tunnel plate, and two load-bearing legs are fixedly connected to the bottom of the discharge plate.

[0015] As a further description of the above technical solution:

[0016] The top of the wind tunnel plate is fixedly connected to a load-bearing bearing column, and the rear side of the air inlet is in contact with the front side of the wind tunnel.

[0017] As a further description of the above technical solution:

[0018] A fixing block is fixed to the top right side of the load-bearing plate 1, a sensor is connected to the bottom of the fixing jaw plate, a wire 1 is fixedly connected to the top of the sensor, and a wire 2 is fixedly connected to the top of the sensor.

[0019] As a further description of the above technical solution:

[0020] Both of the two drive shafts are externally connected to a drive end, and a retaining ring is fixedly connected to the outside of the drive end.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by activating the drive end, the moving jaw plate performs a crushing action under the drive of the eccentric shaft. When heavy construction waste, such as cement blocks, is fed into the crushing structure composed of the moving and fixed jaw plates, if lightweight construction waste, such as plastic or paper, becomes entangled and blocked in the crushing structure, the sensor receives a signal and activates the power tearing arm to tear it apart. The crushed heavy construction waste then enters the impact crusher structure for further crushing and falls directly down, while the lightweight construction waste enters the sorting component below, thereby achieving the classification of heavy and lightweight construction waste and achieving the effect of quickly crushing and classifying construction waste.

[0023] 2. In this utility model, when lightweight construction waste enters the sorting mechanism, it is divided into categories such as plastic and wet paper. With the cooperation of the first sorting structure of the fan, the lightweight construction waste is initially sorted and enters the air duct. Then, it is further subdivided by the second sorting structure of the fan. Different wind forces are used to sort the waste, so that lightweight construction waste of different weights enters the discharge plate. This solves the problems of increased sorting costs and low efficiency, thereby meeting the needs of rapid sorting and processing of large quantities of construction waste.

[0031] 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.

[0032] Reference Figure 1 and Figure 2In one embodiment of this utility model: The load-bearing plate 1 supports the main structure of the entire equipment and provides installation space for internal components. Its movable groove guides the sliding of the movable jaw plate 3. The fixed jaw plate 2 cooperates with the movable jaw plate 3 to form a crushing space, performing initial compression and crushing of the construction waste. Driven by the eccentric shaft 4, the movable jaw plate 3, through a pulley, performs periodic reciprocating motion to crush the construction waste, breaking large pieces of material into smaller particles. The eccentric shaft 4, as the core transmission component, converts the rotational motion into the reciprocating oscillation of the movable jaw plate 3, providing power for the crushing process. The transmission shaft 7 connects the movable jaw plate 3 to the subsequent transmission device, transmitting the crushed material. The load-bearing plate 9 receives the load-bearing plate 1. The system transmits the load and supports components such as the wind tunnel plate 14. The wind tunnel plate 14 uses wind power to perform preliminary sorting of the crushed construction waste, separating lightweight materials from heavy materials. The impact crusher 17 performs secondary impact crushing of the larger construction waste particles after preliminary sorting by the wind tunnel plate 14, further refining them. The load-bearing plate 18 supports the impact crusher 17 and the power tearing arm 19, ensuring the stability of the equipment structure. The power tearing arm 19 tears and shreds the more ductile construction waste, making it easier to classify it later. The classification components, through the structure such as the wind tunnel plate 14, accurately classify the construction waste according to its density, shape, and other characteristics, improving recycling efficiency and resource utilization.

[0033] Reference Figure 2 and Figure 3 The ventilation duct 20 serves to construct a wind-powered conveying channel, providing a closed space for the wind-powered sorting of construction waste and ensuring that the wind force is concentrated on the materials. Multiple air nozzles 21 serve to evenly disperse the wind force, applying force to the construction waste through directional airflow to achieve the separation of light and heavy materials. The second fan 22 serves as a power source, generating a strong airflow to provide continuous power for the wind-powered sorting within the ventilation duct 20. The fixing plate 23 serves to stabilize the left side structure of the ventilation duct 20, ensuring the overall stability of the equipment during the wind-powered sorting process. The fourth load-bearing plate 24 serves to support the cover plate 25 and the discharge plate 27, sharing the weight of the sorting components and providing an installation foundation. The cover plate 25 serves to shield the space above, preventing material splashing and dust diffusion during the sorting process, while also protecting the internal components. The discharge plate 27 serves to receive the sorted construction waste and guide it into the subsequent processing flow. The sorting trough 30 is located on top of the discharge plate 27, serving to divert and collect different types of construction waste, enabling the sorted materials to be transported and recycled separately, improving the accuracy and efficiency of waste sorting.

[0034] Reference Figures 2 to 4The load-bearing column 10 supports the impact crusher 11 and provides it with a pivot point for rotation, ensuring the stable operation of the impact crusher 11. The impact crusher 11 performs secondary impact crushing of construction waste by impacting the material at high speed, further pulverizing it. The load-bearing bearing column 12 fixes and supports the drive shaft 13, reducing friction and shaking during rotation and ensuring transmission stability. The drive shaft 13 transmits power, transferring the rotational motion of the motor or other power source to the impact crusher 11. The drive belt 6 is fitted onto the belt. Inside wheel 5, power is transmitted and different transmission components are connected to achieve efficient power transmission. Transmission belt 8 is sleeved on the outside of transmission shaft 7 and transmits power from the drive shaft to the driven shaft, driving components such as moving jaw plate 3 to move. Conveyor belt 35 is installed on the front side of load-bearing plate 1 and conveys crushed construction waste. Air inlet 15 is fixed inside wind tunnel plate 14 and guides airflow into wind tunnel plate 14 to achieve wind separation. Fan 16 is fixed on the front side of wind tunnel plate 14 and provides power for wind separation.

[0035] The load-bearing leg 26 is fixed to the bottom of the discharge plate 27, serving to support the equipment and maintain its stability. The load-bearing bearing column 12 is fixed to the top of the wind tunnel plate 14, serving to provide auxiliary support and stabilize the transmission components. The air inlet 15 contacts the wind duct 20, serving to connect the wind separation and subsequent processing flow, ensuring smooth material conveying. The fixing block 31 is fixed to the top right side of the load-bearing plate 1, serving to assist in fixing the components and enhance structural stability. The sensor 32 is connected to the bottom of the fixed jaw plate 2, serving to monitor the crushing pressure or material status, and providing real-time data feedback to optimize equipment operation. The first wire 33 and the second wire 34 are connected to the sensor 32, serving to transmit electrical signals and transmit the sensor 32 data to the control system. The drive end 29 is connected to the outside of the drive shaft 7, serving to receive power and transmit it to other components. The fixing ring 28 is fixed to the outside of the drive end 29, serving to fix the drive end 29, prevent it from loosening or shifting, and ensure the stability of power transmission.

[0036] Working principle: When using the equipment, the operator first starts the conveyor belt 35 and the drive end 29. The drive end 29, through the transmission shaft 7 and pulley 5, drives the moving jaw plate 3 and the impact crusher 11. The construction waste to be sorted is then poured onto the conveyor belt 35. Conveyed by the conveyor belt 35, the construction waste enters the crushing structure composed of the moving jaw plate 3 and the fixed jaw plate 2 for initial crushing. The initially crushed construction waste then enters the impact crusher 11 for further crushing. Heavy construction waste falls directly to the bottom, while light construction waste, after passing through the wind tunnel plate 14, is carried by the wind force of the fan 16 and enters the sorting component through the air inlet 15.

[0037] Construction waste enters the sorting unit and passes through the air duct 20 under the wind power of fan 16. Slightly heavier lightweight construction materials will enter the discharge plate 27 below. Under the wind power generated by fan 22, the slightly lighter lightweight construction materials pass through the air nozzle 21 and enter the sorting trough 30 by the wind power, falling into the sorting trough above. This achieves the separation of light and heavy construction waste and saves electricity and manpower.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
