Abstract

Technical Field
[0001] This utility model relates to the field of construction waste crushing technology, and in particular to a device for sorting, recycling, crushing and processing urban construction waste. Background Technology
[0002] Currently, in the sorting and recycling of urban construction waste, there are brick and tile wastes, such as clay bricks, hollow bricks, and ceramic waste. When using traditional crushing equipment to crush and recycle them, the following problems exist: during dry crushing, brittle materials are easily over-crushed, producing 20-40% powder, causing serious environmental pollution. When using a fixed spraying device for covering, uneven spraying occurs, which can easily lead to local over-wetting and adhesion and blockage. To address these issues, we propose an urban construction waste sorting, recycling, crushing, and processing device. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for the classification, recycling, crushing, and processing of urban construction waste.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A device for sorting, recycling, crushing, and processing urban construction waste includes a crushing box with a crushing mechanism inside. A conveying mechanism is mounted on one side of the crushing box, and a humidity sensor array is installed on the conveying mechanism. A supporting mechanism is provided on the upper side of the crushing box, and a movable plate is movably mounted on the supporting mechanism. A spraying mechanism is provided on the movable plate. A reciprocating pushing mechanism is installed at one end of the supporting mechanism and is connected to the movable plate. An infrared scanner is installed on the lower side of the supporting mechanism.
[0006] Preferably, the crushing mechanism includes a second drive motor installed on one side of the crushing box. The output shaft of the second drive motor is connected to two crushing rollers through a gear set. One end of the two crushing rollers is rotatably connected to one side inside the crushing box. Multiple crushing cones are provided at equal intervals on the side wall of the crushing rollers.
[0007] Preferably, the conveying mechanism includes a support frame fixed to one side of the crushing box, a conveyor belt installed on the support frame, a humidity sensor array disposed on the conveyor belt, a feed hood provided on the upper side of the crushing box, and one end of the conveyor belt extending to the upper end of the feed hood.
[0008] Preferably, the bearing mechanism includes first hydraulic cylinders installed on both sides of the upper end of the crushing box, the piston rod ends of the two first hydraulic cylinders are connected to the bearing frame through a rotating shaft, two support columns are provided on one side of the crushing box, and second hydraulic cylinders are installed on the upper end of the support columns, and the piston rod ends of the two second hydraulic cylinders are connected to the lower side of the bearing frame through a rotating shaft.
[0009] Preferably, multiple sliders are fixed at equal intervals on both sides of the movable plate, and grooves are provided on the opposite side walls of the support frame, with the sliders installed in the grooves.
[0010] Preferably, the spraying mechanism includes fixed pipes fixed to both sides of the upper end of the movable plate, a connecting pipe connecting the two fixed pipes, a water supply pipe connected to one end of the connecting pipe, one end of the water supply pipe penetrating the side wall of the support frame and extending to one side of the support frame, and multiple nozzles connected at equal intervals at the lower end of the fixed pipe, the nozzles penetrating the side wall of the movable plate and corresponding to the conveyor belt.
[0011] Preferably, the reciprocating pushing mechanism includes a protective box installed on one side of the support frame, a mounting frame installed inside the protective box, two turntables rotatably connected to the mounting frame, a first drive motor installed on one side of the mounting frame, the output shaft of the first drive motor connected to one end of one of the turntables, a rotating rod fixed between the two turntables, two connecting rings rotatably connected to the rotating rod, one end of the connecting rings connected to a pull rod, and one end of the two pull rods rotatably connected to one side of the moving plate.
[0012] In this invention, when waste enters the conveyor belt, the infrared scanner identifies the material type, such as clay bricks / ceramics. The PLC calls the preset humidity curve and starts the composite motion of the spray frame. The humidity sensor of the conveyor belt provides real-time feedback to control the spray intensity, so that the moisture content of the material accurately reaches the optimal crushing range, while avoiding excessive hydration of the clay. After the material is evenly sprayed with water, it enters the crushing box and is crushed by the crushing cone.
[0013] The crushing steps in this utility model are as follows:
[0014] 1. Material Conveying and Identification: Brick and tile waste is placed on a conveyor belt and supported by a support frame. As the conveyor belt operates, an infrared scanner identifies the material type, such as clay bricks or ceramics.
[0015] 2. Humidity Control and Spraying: After the infrared scanner identifies the material type, the PLC calls the preset humidity curve and starts the spraying mechanism. The first drive motor drives the turntable and rotating rod to rotate, and through the connecting ring and pull rod, the moving plate reciprocates within the slide groove of the support frame. Simultaneously, the first and second hydraulic cylinders adjust the angle and position of the support frame, realizing the combined movement of the spraying frame. The water supply pipe delivers water to the fixed pipe, which sprays water onto the material on the conveyor belt through the nozzles at its lower end. The humidity sensor array provides real-time feedback on the humidity of the material on the conveyor belt, thereby controlling the spraying intensity to ensure that the material's moisture content reaches the optimal crushing range.
[0016] 3. Material Crushing: The material, after being uniformly sprayed with water, enters the crushing chamber through the feed hood. The second drive motor drives two crushing rollers to rotate via a gear set, and the crushing cones on the crushing rollers crush the material.
[0017] This utility model has the following advantages:
[0018] 1. Traditional dry crushing produces 20-40% powder, causing serious environmental pollution. This device avoids over-crushing of materials through precise humidity control, reduces dust generation, and effectively reduces environmental pollution.
[0019] 2. By using an infrared scanner to identify the material type and call up the preset humidity curve, combined with real-time feedback from the humidity sensor array, the spray intensity is controlled so that the material moisture content accurately reaches the optimal crushing range, thereby improving crushing efficiency and quality.
[0020] 3. The use of a composite-moving spray frame avoids the problem of uneven spraying in traditional fixed spray devices, prevents localized overwetting of materials leading to adhesion and blockage, ensures normal operation of the equipment, and reduces maintenance costs.
[0021] In summary, the crushing device of this utility model reduces dust generation, effectively reducing environmental pollution. At the same time, it can accurately bring the material moisture content to the optimal crushing range, thereby improving crushing efficiency and quality. In addition, the uniform spraying setting can prevent localized over-wetting of materials, which can lead to adhesion and blockage, ensuring the normal operation of the equipment and reducing maintenance costs.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figure 1-5 A device for sorting, recycling, and crushing urban construction waste includes a crushing box 5, which contains a crushing mechanism. A conveying mechanism is mounted on one side of the crushing box 5, and a humidity sensor array 7 is installed on the conveying mechanism. A carrying mechanism is located on the upper side of the crushing box 5, and a movable plate 18 is movably mounted on the carrying mechanism. A spraying mechanism is installed on the movable plate 18. A reciprocating pushing mechanism is installed at one end of the carrying mechanism and is connected to the movable plate 18. An infrared scanner 11 is installed on the lower side of the carrying mechanism. The infrared scanner 11 uses infrared technology to analyze the infrared light reflected by brick and tile waste of different materials. Materials such as clay bricks and ceramics have different physical and chemical properties, and their absorption and reflection characteristics of infrared light also differ. Through a built-in recognition algorithm, the infrared scanner 11 can quickly and accurately determine whether the material is clay brick, ceramic, or other types of brick and tile waste.
[0030] The crushing mechanism includes a second drive motor 22 installed on one side of the crushing box 5. The output shaft of the second drive motor 22 is connected to two crushing rollers 19 through a gear set 21. One end of the two crushing rollers 19 is rotatably connected to one side inside the crushing box 5. Multiple crushing cones 20 are evenly spaced on the side wall of the crushing rollers 19. The second drive motor 22 drives the two crushing rollers 19 to rotate through the gear set 21, and the crushing cones 20 on the crushing rollers 19 crush the material.
[0031] The conveying mechanism includes a support frame 6 fixed to one side of the crushing box 5, a conveyor belt 8 installed on the support frame 6, a humidity sensor array 7 set on the conveyor belt 8, a feed hood 4 provided on the upper side of the crushing box 5, one end of the conveyor belt 8 extending to the upper end of the feed hood 4, a nozzle spraying water onto the material on the conveyor belt 8, and the humidity sensor array 7 providing real-time feedback on the humidity of the material on the conveyor belt 8, thereby controlling the spray intensity and ensuring that the moisture content of the material reaches the optimal crushing range.
[0032] The bearing mechanism includes first hydraulic cylinders 3 installed on both sides of the upper end of the crushing box 5. The piston rod ends of the two first hydraulic cylinders 3 are connected to the bearing frame 2 through a rotating shaft. Two support columns 10 are provided on one side of the crushing box 5. Second hydraulic cylinders 9 are installed on the upper end of the support columns 10. The piston rod ends of the two second hydraulic cylinders 9 are connected to the lower side of the bearing frame 2 through a rotating shaft. The support angle and height position can be adjusted as needed to fully adapt to different specifications of crushers.
[0033] Multiple sliders 14 are fixed at equal intervals on both sides of the movable plate 18. Slide grooves 13 are provided on opposite side walls of the support frame 2, and the sliders 14 are installed in the slide grooves 13. The spraying mechanism includes fixed pipes 15 fixed to both sides of the upper end of the movable plate 18. A connecting pipe connects the two fixed pipes 15, and one end of the connecting pipe is connected to a water supply pipe 1. One end of the water supply pipe 1 penetrates the side wall of the support frame 2 and extends to one side of the support frame 2. Multiple nozzles are connected at equal intervals to the lower end of the fixed pipes 15. The nozzles penetrate the side wall of the movable plate 18 and correspond to the conveyor belt 8. After the infrared scanner 11 completes the material type identification, it transmits the information to the PLC (Programmable Logic Controller). The PLC acts as the entire humidity control system. The core of the system is to accurately calculate the required spraying intensity and time based on a preset humidity curve and the type and characteristics of the material. Different types of brick and tile waste, such as clay bricks and ceramics, have different optimal crushing moisture contents. The humidity sensor array 7 is distributed on the conveyor belt 8, which can monitor the humidity of the material in real time and feed the monitored humidity data back to the PLC. The PLC adjusts the spraying intensity in a timely manner based on the feedback information. If the material humidity is lower than the optimal crushing range, the PLC will increase the spraying intensity; if the material humidity is close to or exceeds the optimal crushing range, the PLC will reduce the spraying intensity or stop spraying water, thereby ensuring that the material moisture content accurately reaches the optimal crushing range, while avoiding excessive hydration of clay.
[0034] The reciprocating pushing mechanism includes a protective box 17 installed on one side of the support frame 2. A mounting frame 26 is installed inside the protective box 17. Two turntables 23 are rotatably connected to the mounting frame 26. A first drive motor 12 is installed on one side of the mounting frame 26. The output shaft of the first drive motor 12 is connected to one end of one of the turntables 23. A rotating rod 24 is fixed between the two turntables 23. Two connecting rings 25 are rotatably connected to the rotating rod 24. A pull rod 16 is connected to one end of the connecting rings 25. One end of the two pull rods 16 is rotatably connected to one side of the moving plate 18. The rotational motion of the turntables 23 is converted into the elliptical trajectory motion of the connecting rings 25 through the rotating rod 24, thereby driving the pull rods 16 to generate a horizontal reciprocating thrust. The ratio of the turntable diameter to the length of the rotating rod is 1:1.5. This ratio design can balance the stroke distance and the driving torque, ensuring that the stroke range of the moving plate 18 reaches 300-500mm, while maintaining a reciprocating frequency of 2-4 times / second.
[0035] In this invention, when waste enters the conveyor belt 8, the infrared scanner identifies the material type, such as clay bricks / ceramics. The PLC calls the preset humidity curve and starts the composite motion of the spray frame. The humidity sensor 7 of the conveyor belt provides real-time feedback to control the spray intensity, so that the moisture content of the material accurately reaches the optimal crushing range, while avoiding excessive hydration of the clay. After the material is evenly sprayed with water, it enters the crushing box 5 and is crushed by the crushing cone.
[0036] The crushing steps in this utility model are as follows:
[0037] 1. Material Conveying and Identification: Brick and tile waste is placed on conveyor belt 8 and supported by support frame 6. During operation of conveyor belt 8, infrared scanner 11 identifies the material type, such as clay bricks and ceramics.
[0038] 2. Humidity Control and Spraying: After the infrared scanner 11 identifies the material type, the PLC calls the preset humidity curve and starts the spraying mechanism. The first drive motor 12 drives the turntable 23 and the rotating rod 24 to rotate, and through the connecting ring 25 and the pull rod 16, the moving plate 18 reciprocates in the slide groove 13 of the support frame 2. At the same time, the first hydraulic cylinder 3 and the second hydraulic cylinder 9 can adjust the angle and position of the support frame 2 to realize the compound movement of the spraying frame. The water supply pipe 1 delivers water to the fixed pipe 15, and sprays water onto the material on the conveyor belt 8 through the nozzle at its lower end. The humidity sensor array 7 provides real-time feedback on the humidity of the material on the conveyor belt 8, thereby controlling the spraying intensity to ensure that the material moisture content reaches the optimal crushing range.
[0039] 3. Material crushing: The material, after being uniformly sprayed with water, enters the crushing chamber 5 through the feed hood 4. The second drive motor 22 drives the two crushing rollers 19 to rotate through the gear set 21, and the crushing cones 20 on the crushing rollers 19 crush the material.
