Description

Technical Field

[0001] This utility model relates to the field of urban waste treatment, specifically to an intelligent sorting machine for urban domestic waste that combines visible light and X-rays. Background Technology

[0002] Current municipal solid waste sorting equipment requires all waste to be finely crushed before sorting begins. This crushing process completely destroys previously intact reusable items. This not only wastes materials but also exposes previously sealed toxic and harmful components to the environment, causing pollution, especially when destroying electronic waste. Municipal solid waste sorting equipment uses the material composition of the waste as the basis for sorting. If the waste contains high-value lost items (such as cash, documents, precious metal jewelry, etc.), they will not only be damaged during the crushing process but will also be treated as ordinary items in traditional sorting processes.

[0003] Traditional manual sorting or existing machine vision sorting equipment relies mainly on images generated by visible light for sorting information. It cannot effectively judge the material of the sorted object, especially the invisible internal material, and cannot determine whether it contains toxic or harmful materials.

[0004] Therefore, there is an urgent need to design an intelligent sorting machine that combines visible light and X-rays for municipal solid waste to solve the problems in the background technology. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a smart sorting machine for municipal solid waste using visible light and X-rays, comprising a frame, a feeding mechanism, a transport mechanism, an image acquisition mechanism, and a sorting mechanism. The feeding mechanism is arranged at one end of the frame and is equipped with a vibrating feeder feeding chute housing. The vibrating feeder feeding chute housing is connected to a vibrating feeder feeding chute. A vibrating feeder is arranged above the vibrating feeder feeding chute and connected to a transport mechanism on one side. An image acquisition mechanism is arranged above the transport mechanism and includes a composite image acquisition device housing. A sorting mechanism is arranged on one side of the composite image acquisition device housing.

[0006] Preferably, the equipment frame consists of a bottom frame and a main frame. The main frame is fixed to the bottom frame with screws. A transport mechanism is placed inside the main frame, and an image acquisition mechanism is located at the top of the main frame.

[0007] Preferably, a sorting and picking device is fixed to the top of the main frame of the equipment with screws, and a compressed air blowing device is fixed to the bottom with screws.

[0008] Preferably, the main frame of the equipment is equipped with a side shell on the side and a rear shell on the rear.

[0009] Preferably, the feeding mechanism includes a vibrating feeder, a vibrating feeder feeding chute is connected below the vibrating feeder, and a vibrating feeder feeding chute housing is mounted on the vibrating feeder feeding chute.

[0010] Preferably, the transport mechanism consists of an end drive roller, a checkered rubber conveyor belt, a geared motor, and a front drive roller. One end of the checkered rubber conveyor belt is connected to the front drive roller, and the other end is connected to the end drive roller. The front drive roller is connected to the geared motor via a coupling.

[0011] Preferably, the image acquisition mechanism consists of a composite image acquisition device housing, an X-ray generator and image acquisition unit, a visible light generator and image acquisition unit, and an X-ray information detector. The X-ray generator and image acquisition unit is installed inside the composite image acquisition device housing. The X-ray generator and image acquisition unit is fixed to the equipment frame by a matching bracket. A visible light generator and image acquisition unit is installed on one side of the X-ray generator and image acquisition unit. The X-ray information detector is installed below the X-ray generator and image acquisition unit and is connected to the X-ray generator and image acquisition unit by wired or wireless transmission.

[0012] Preferably, the housing of the composite image acquisition device has X-ray shielding composite lead plates fixed on its four sides.

[0013] Preferably, the material sorting mechanism consists of a small-diameter waste sorting hopper shell, a small-diameter waste sorting hopper, a compressed air blowing device, and a sorting and picking device. The sorting and picking device is located at the end of the square rubber conveyor belt. A compressed air blowing device is located below the sorting and picking device. A small-diameter waste sorting hopper is located on one side of the sorting and picking device. A small-diameter waste sorting hopper shell is located outside the small-diameter waste sorting hopper.

[0014] The advantages of this invention compared to existing technologies are as follows: the sorting operation is moved forward to before the crushing process. By using visible light and X-ray composite images combined with AI visual recognition technology, the material and internal structure of the waste are accurately determined. Special treatment is carried out during the sorting process to avoid damage and diffusion of these materials in subsequent processing. This achieves efficient and accurate sorting of municipal solid waste, reduces the workload of subsequent processing, improves sorting efficiency, avoids damage to reusable items during the crushing process, protects the integrity of the items, improves the recycling rate, and prevents environmental pollution.

[0021] In specific implementation of this utility model, such as Figures 1 to 4 As shown, a smart sorting machine combining visible light and X-rays for municipal solid waste is provided. Its workflow includes the following steps:

[0022] Step 1: Waste Discharge

[0023] Municipal solid waste awaiting sorting first enters the vibrating feeder 20, serving as the starting point of the feeding mechanism. The vibrating feeder 20 receives and guides the waste into subsequent processes. The waste slides into the equipment through the vibrating feeder discharge chute 18, where the discharge chute housing 15 is mounted above the discharge chute 18, providing protection and guidance. The vibrating feeder 20 starts vibrating, evenly spreading the waste onto the grid-shaped rubber conveyor belt 8, preparing it for subsequent sorting operations.

[0024] Step 2: Waste Transportation

[0025] A grid-shaped rubber conveyor belt 8 is connected at one end to a front-end drive roller 16 and at the other end to an end-end drive roller 7, forming a closed-loop conveying system. Waste is evenly spread across the grid of the conveyor belt 8 by a vibrating feeder 20 to prevent displacement during transport. The front-end drive roller 16 is connected to a geared motor 14 via a coupling, providing power to the grid-shaped rubber conveyor belt 8. The geared motor 14 drives the front-end drive roller 16 to rotate, thereby causing the grid-shaped rubber conveyor belt 8 to convey the waste at a uniform speed. The end-end drive roller 7 and the front-end drive roller 16 together support the grid-shaped rubber conveyor belt 8, ensuring its stable operation.

[0026] Step 3: Image Acquisition

[0027] The composite image acquisition device housing 9 is positioned above the transport mechanism and houses an X-ray generator and image acquisition unit 10 and a visible light generator and image acquisition unit 11. The X-ray generator and image acquisition unit 10 is fixed to the main frame 6 of the equipment via a matching bracket, emitting X-rays to penetrate the waste and acquire X-ray images. The visible light generator and image acquisition unit 11 is positioned to one side of the X-ray generator and image acquisition unit 10, acquiring visible light images of the waste. An X-ray information detector 13 is positioned below the X-ray generator and image acquisition unit 10, connected via wired or wireless transmission to receive and process X-ray image information. An X-ray shielding composite lead plate 12 is fixed to the four walls of the composite image acquisition device housing 9 to prevent X-ray leakage and ensure operator safety.

[0028] Step 4: Image Processing and Sorting Instruction Generation

[0029] This device is equipped with a central control system, the main body of which is a PCB board with a PLC main control chip and auxiliary control circuits. The central control system receives image information from the visible light generator and image acquisition unit 11 and the X-ray information detector 13, analyzes and processes it through AI visual recognition technology, determines the main material, size, shape and other physical characteristics of the objects in the rubber conveyor belt grid, and issues corresponding instructions to the sorting execution mechanism behind it according to the pre-set program and the speed of the rubber conveyor belt.

[0030] Step 5: Sorting Execution

[0031] The sorting and picking device 4 is located at the end of the grid-shaped rubber conveyor belt 8. According to the instructions of the central control system, it picks up the waste that needs to be sorted. The sorting and picking device 4 typically consists of two clamping mechanisms, two negative pressure suction mechanisms, and two electromagnetic suction mechanisms. Other picking devices or the number of picking devices can be added according to actual needs. The compressed air blowing device 3 is located below the sorting and picking device 4. For small-diameter waste and other difficult-to-pick-up waste, it is blown into the front recycling port and finally dropped into the conveying mechanism below.

[0032] Step Six: Waste Sorting and Summarizing

[0033] Small-diameter waste sorting hopper 2 receives small-diameter waste blown in by compressed air blowing device 3. The small-diameter waste sorting hopper shell 1 surrounds the small-diameter waste sorting hopper 2, serving both protection and guiding functions. In addition, this device is equipped with other conveying mechanisms for receiving different types of waste sorted by sorting and picking device 4 and transporting them to the corresponding processing areas. Other waste that is not suitable for sorting falls directly into the waste inlet below for further processing.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
