Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction solid waste treatment technology, and in particular to a waste concrete separation device for concrete processing. Background Technology
[0002] With the rapid development of the construction industry, the amount of waste concrete generated during construction and demolition has increased significantly. If this waste concrete is dumped haphazardly, it not only occupies land resources but also causes environmental pollution due to the difficulty in natural degradation of components such as cement and sand. In response to the call for green building and resource recycling, it is necessary to separate waste concrete into reusable materials using specialized equipment. Therefore, a waste concrete separation device for concrete processing is required.
[0003] Existing waste concrete separation equipment for concrete processing typically consists of a feeding mechanism, a crushing mechanism, a conveying mechanism, and a power mechanism. The inner wall of the feeding mechanism is lined with wear-resistant plates to receive the waste concrete to be processed, and the material is guided slowly into the crushing mechanism by gravity to avoid material accumulation and blockage. The crushing mechanism is commonly a jaw crusher assembly, consisting of a fixed jaw plate, a movable jaw plate, and an eccentric shaft. The power system drives the eccentric shaft to rotate, causing the movable jaw plate to reciprocate. Through the squeezing and shearing action between the movable jaw plate and the fixed jaw plate, large pieces of waste concrete are crushed into smaller pieces.
[0004] Existing waste concrete separation equipment for concrete processing lacks a reliable protective structure at the feed inlet of the crushing process. When large pieces of waste concrete enter the crushing mechanism, under the strong squeezing action of the moving jaw plate and the fixed jaw plate, some of the crushed material will deviate from the preset trajectory due to the instantaneous impact force and splash outward from the feed inlet. This splashed material not only impacts the equipment casing, causing wear on components, but also scatters into the surrounding operating area. If operators are close by, they are easily injured by the splashed material. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a waste concrete separation device for concrete processing, which aims to improve the problem of large pieces of material splashing out of the crusher after being squeezed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste concrete separation device for concrete processing, comprising a support platform, a main frame fixedly connected to the top of the support platform, a protective component provided on the outer wall of the main frame, a screening component provided at the bottom of the main frame, a flywheel rotatably connected to the outer wall of the main frame, a belt slidably connected to the outer wall of the flywheel, a motor fixedly connected to the top of the support platform, and the inner wall of the belt slidably connected to the outer wall of the motor output end; The protective component includes a second sliding block, which is slidably connected to the inner wall of the main frame. A first sliding block is fixedly connected to the outer wall of the second sliding block. A fixed block is slidably connected to the outer wall of the first sliding block. The outer wall of the fixed block is fixedly connected to the outer wall of the main frame. A baffle is slidably connected to the inner wall of the main frame. A slot is provided on the inner wall of the baffle. The outer wall of the second sliding block is slidably connected to the inner wall of the slot. A fixed rod is fixedly connected inside the fixed block. A reset component is provided on the outer wall of the fixed rod.
[0007] As a further description of the above technical solution: The reset assembly includes a spring, one end of which is fixedly connected to the outer wall of the fixed rod, and the other end of which is fixedly connected to the outer wall of the sliding block.
[0008] As a further description of the above technical solution: The screening assembly includes a screen, the outer wall of which is disposed at the bottom of the main frame.
[0009] As a further description of the above technical solution: A screen box is fixedly connected to the outer wall of the screen mesh, and a screen discharge port is fixedly connected to the outer wall of the screen box.
[0010] As a further description of the above technical solution: The outer wall of the upper discharge port is fixedly connected to the outer wall of the screen mesh, and the outer wall of the screen box is fixedly connected to the lower discharge port.
[0011] As a further description of the above technical solution: A support frame is fixedly connected to the inner wall of the sieve box, and a vibrator is fixedly connected to the top of the support frame.
[0012] As a further description of the above technical solution: The bottom of the sieve box is provided with a second support frame, and the top of the second support frame is fixedly connected with a support block.
[0013] As a further description of the above technical solution: A second spring is provided on the top of the support block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, firstly, sliding block one is pressed to drive sliding block two to slide, and then sliding block one is pressed to squeeze spring one. When sliding block one slides to the outer wall of the fixed rod, the baffle slides downward. When the baffle is resisted, sliding block one is released, and the reaction force of spring one drives sliding block one to reset. This achieves the effect of effectively intercepting the splashed material during crushing, solves the problem of large pieces of material being squeezed and splashed out of the crusher, and improves the safety of the operation of the waste concrete separation equipment for concrete processing. 2. In this utility model, the vibrator is driven first, which drives the entire machine to vibrate. At this time, the crushed material is discharged through the main frame and falls into the top of the screen. Since the screen is tilted downwards, larger materials can be transported downwards by vibration. The linear screen machine intercepts the substandard large pieces of material in advance and returns them for re-crushing, which reduces the crushing load on the downstream equipment and solves the problem of excessive wear caused by large pieces of material directly entering the downstream equipment. This improves the practicality of the waste concrete separation equipment for concrete processing. Attached Figure Description

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] Reference Figure 1 and Figures 3-5 This utility model provides an embodiment of a waste concrete separation device for concrete processing, including a support platform 1. The support platform 1 bears the weight of the entire device, providing a stable installation foundation for each component and preventing displacement or tilting due to vibration during operation, thus ensuring stable separation operations. A main frame 2 is fixedly connected to the top of the support platform 1. The main frame 2 is used to install and fix core components such as the fixing component and the screening component, providing support and a connecting frame for each component and ensuring that each component maintains a relatively stable positional relationship during operation. A protective component is provided on the outer wall of the main frame 2 to prevent materials from flying out when squeezed. The main frame 2 of the main frame is equipped with a screening component at the bottom. The screening component is used to screen the crushed material and screen out the unqualified material for secondary crushing. The flywheel 4 is rotatably connected to the outer wall of the main frame 2. The flywheel 4 is used to transmit the power of the motor 3. The outer wall of the flywheel 4 is slidably connected to the belt 5. The belt 5 is used to connect the flywheel 4 and the output end of the motor 3, and transmit the power generated by the motor 3 to the flywheel 4 to achieve efficient power transmission. The motor 3 is fixedly connected to the top of the support platform 1. The motor 3 serves as the power source of the equipment and provides power for the rotation of the flywheel 4 and subsequent separation action. The inner wall of the belt 5 is slidably connected to the outer wall of the output end of the motor 3. The protective component includes a second sliding block 20, which connects a first sliding block 8 and a baffle 6, serving to transmit motion and provide linkage. The second sliding block 20 is slidably connected to the inner wall of the main frame 2, and slides up and down in conjunction with the main frame 2. A first sliding block 8 is fixedly connected to the outer wall of the second sliding block 20, sliding within a fixed block 7 to restrict the direction of movement of the second sliding block 20 and prevent it from shifting during sliding, thus ensuring the accuracy of the protective component's movement. A fixed block 7 is slidably connected to the outer wall of the first sliding block 8, fixing it to the outer wall of the main frame 2 and providing a sliding track for the first sliding block 8, allowing it to reciprocate and providing stable support for the movement of the protective component. The outer wall of the fixed block 7 is fixedly connected to the outer wall of the main frame 2. A baffle 6 is slidably connected to the inner wall of the main frame 2, protecting materials splashed out when compressed, ensuring the safety of equipment operation and personnel. A slot 11 is provided on the inner wall of the baffle 6. The slot 11 is used to accommodate the second sliding block 20, achieving a fixed effect. The fixing block 7 is internally fixedly connected to the fixing rod 9, which is used to install the reset component and provide a stable mounting carrier for the reset component. The outer wall of the fixing rod 9 is provided with the reset component. The reset component is used to drive the first sliding block 8 and the second sliding block 20 back to their initial positions after the protective component completes its protective action. The reset component includes a spring 10, which is used to provide reset power for the first sliding block 8. When the first sliding block 8 is displaced by external force, the spring 10 can generate a reverse pulling force or pushing force through its own elastic deformation, driving the first sliding block 8 back to its initial position. This ensures that the first sliding block 8 can be accurately reset after each operation without affecting subsequent processes. One end of the spring 10 is fixedly connected to the outer wall of the fixing rod 9, which is used to fix one end of the spring 10 and provide a stable force support point for the spring 10, preventing the spring 10 from shifting its position during deformation. The other end of the spring 10 is fixedly connected to the outer wall of the first sliding block 8.
[0019] Reference Figure 2The screening component includes a screen 15, which is used to classify and screen materials. Through the specific size of its mesh openings, particles larger than the mesh openings remain on the screen surface, while particles smaller than the mesh openings pass through, achieving the effect of separating materials of different particle sizes. The outer wall of the screen 15 is located at the bottom of the main frame 2, and a discharge port is provided at the bottom of the main frame 2. A screen box 12 is fixedly connected to the outer wall of the screen 15. The screen box 12 is used to hold the screen 15 and the material to be screened, preventing the material from spilling from the sides during the screening process. The bottom can also hold the screened material. A screen discharge port 16 is fixedly connected to the outer wall of the screen box 12, used to discharge the material from the screen 15. The retention of large-diameter materials allows for the orderly collection of large particles after screening, preventing them from accumulating on the screen 15 and affecting subsequent screening efficiency. The outer wall of the screen discharge port 16 is fixedly connected to the outer wall of the screen 15. The outer wall of the screen box 12 is fixedly connected to the under-screen discharge port 17, which is used to discharge small-diameter materials that have passed through the screen 15. This, in conjunction with the screen discharge port 16, enables the separate collection of materials of different diameters, improving the classification efficiency after screening. The inner wall of the screen box 12 is fixedly connected to a support frame 13, which is used to fix the vibrator 14, providing a stable installation position for the vibrator 14 and ensuring that the vibrator 14 does not vibrate during operation. In case of detachment or displacement, a vibrator 14 is fixedly connected to the top of the support frame 13. The vibrator 14 generates vibration power, which drives the screen box 12 and screen 15 to vibrate synchronously through its own high-frequency vibration, so that the material is quickly dispersed and moved on the screen 15, avoiding material blockage of the screen 15 mesh, thereby improving the screening speed and screening effect. A support frame 21 is set at the bottom of the screen box 12. The support frame 21 is used to support the entire screen box 12 and screening components, separating the screen box 12 from the ground or other equipment foundations, and reserving material collection space below the under-screen discharge port 17. A support block 19 is fixedly connected to the top of the support frame 21. The support block 19 is used for fixing. One end of the fixed spring 18 is fixed, and the contact area between the spring 18 and the support frame 21 is increased to avoid the spring 18 causing excessive local pressure damage to the support frame 21. The top of the support block 19 is equipped with the spring 18, which is used to buffer the vibration of the screen box 12. When the vibrator 14 drives the screen box 12 to vibrate, the spring 18 absorbs part of the vibration energy through its own elastic deformation, reducing the impact of the screen box 12 vibration on the support frame 21 and surrounding equipment, thereby reducing vibration noise and protecting the equipment structure. One end of the spring 18 is fixedly connected to the top of the support block 19, and the other end of the spring 18 is fixedly connected to the bottom of the screen box 12.
[0020] Working principle: When baffle 6 is needed for protection, firstly, sliding block 8 is pressed to drive sliding block 20 to slide. Then, sliding block 8 is pressed to compress spring 10. When sliding block 8 slides to the outer wall of fixed rod 9, baffle 6 slides downward. When baffle 6 encounters resistance, sliding block 8 is released. The reaction force of spring 10 drives sliding block 8 to reset. Finally, the reset of sliding block 8 drives sliding block 20 to slide into slot 11, fixing baffle 6 to the inner wall of main frame 2, thus solving the problem of large pieces of material splashing out of the crusher due to compression.
[0021] When the screen 15 is used to filter materials, the vibrator 14 is driven first. The vibrator 14 drives the whole machine to vibrate. At this time, the crushed material is discharged through the main frame 2 and falls into the top of the screen 15. Since the screen 15 is inclined downward, larger materials can be transported downward through vibration and discharged through the screen outlet 16 for secondary crushing. Then, qualified materials are screened out through the gaps of the screen 15 and fall into the screen box 12. They slide downward through vibration and are finally discharged through the screen outlet 17. This achieves the effect of precise particle size control and improves the finished product qualification rate.
