Description

Technical Field

[0001] The present invention relates to the technical field of construction solid waste treatment, and specifically to a construction solid waste treatment device based on multi-stage crushing and intelligent sorting. Background Art

[0002] As construction progresses, if solid waste at the construction site is discarded or handled improperly, it will occupy a large amount of land and may also pollute the soil, water and air. By treating these solid wastes, the useful resources in them can be separated and put back into production and use, thus realizing the recycling of resources.

[0003] For example, the publication number CN109847883A discloses a construction waste recycling and utilization device suitable for low-temperature conditions, in which the intermittent feeding assembly is fixedly connected to the crushing device, the crushing device and the intermittent feeding assembly are connected by a belt drive, the metal separation assembly is fixedly connected to the lower end of the crushing device, the metal separation assembly is located below the intermittent feeding assembly, the metal separation assembly and the crushing device are connected by a belt drive, the solidification stirring assembly is fixedly connected to the base, and the solidification stirring assembly is located below the right end of the crushing device.

[0004] However, in the existing technology, the solid waste generated during the construction process is complex in composition and contains materials of various hardness and properties. For materials such as concrete blocks and tiles with low hardness but brittle texture and large volume, due to their special physical properties, when such materials enter the crusher, they cannot adapt to the size of the crushing chamber and will continue to slide on the surface of the high-speed crushing components. The continuously sliding block materials will not only occupy a large amount of crushing chamber space, but also hinder other solid waste that meets the feed size from entering the crushing area, causing blockage in the feed port and forcing the equipment to be frequently shut down for cleaning; the intense friction between the block materials and the inner wall of the crusher will accelerate the wear of key components such as wear-resistant liners, hammer heads, and screens. In addition, a single crushing and screening process is difficult to process and screen solid waste particles to the required particle size, and cannot meet the uniformity and fineness requirements of the crushing operation. If repeated crushing and screening is used, not only will the operation time of loading and unloading, screening and other links be increased, but each repeated operation will also require manual or mechanical intervention, significantly increasing the operation frequency and time cost. These additional time consumption will extend the equipment downtime, compress the effective working time, and ultimately lead to a decrease in overall production efficiency. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1: Reference Figure 1 - Figure 10 As shown: A construction solid waste treatment device based on multi-stage crushing and intelligent sorting includes a base plate 2, a support frame 16 is fixedly connected to the top of the base plate 2, a crushing box 1 is fixedly connected to the top of the support frame 16, two first rotating rods 13 are rotatably connected to the inside of the crushing box 1, a screening mechanism 5 is installed on one side of the base plate 2, a crushing mechanism 4 is installed on the side wall of the crushing box 1, a second drive motor 3 is installed on the top of the base plate 2, and a belt transmission assembly 31 is fixedly connected to the output end of the second drive motor 3;

[0035] The crushing mechanism 4 includes a first fixed frame 41, a power assembly and a crushing assembly connected to the belt drive assembly 31. The power assembly is used to control the crushing assembly to initially impact and crush the solid waste. The crushing assembly includes a first sliding rod 42 fixedly connected to the inner side of the top of the first fixed frame 41, a second movable rod 49 and a crushing knife 481. The top of the second movable rod 49 is fixedly connected to a sliding sleeve 491 slidably connected to the first sliding rod 42. The top of the crushing knife 481 is fixedly connected to a lifting frame 48 slidably connected to the second movable rod 49.

[0036] The screening mechanism 5 includes a base 52, a screening box 59, a driving assembly and a sorting assembly. The sorting assembly is used to control the screening box 59 to complete the solid waste fragment screening work. The driving assembly includes a first moving block 53 and a second moving block 56. The side wall of the first moving block 53 is rotatably connected to the third crank 54. One end of the third crank 54 is rotatably connected to the driving rod 55. One end of the driving rod 55 is rotatably connected to the side wall of the second moving block 56.

[0037] The side wall of the lifting frame 48 is rotatably connected to a connecting frame 46. The bottom of the connecting frame 46 is fixedly connected to a first movable rod 45. A sliding block 451 is slidably connected to the outer surface of the first movable rod 45. A second rotating rod 452 is fixedly connected to the side wall of the sliding block 451. The second rotating rod 452 is rotatably connected to the bottom end of the middle portion of the first fixed frame 41. One end of the second rotating rod 452 is fixedly connected to a second crank 453. One end of the second crank 453 is rotatably connected to a driven block 454. The driven block 454 is slidably connected to the first guide hole 441. The active rod 43 is fixedly connected to one end of the belt drive assembly 31. A first spring 47 is provided between the sliding block 451 and the connecting frame 46. The first spring 47 is sleeved on the outer surface of the first movable rod 45.

[0038] In this embodiment, when it is necessary to effectively treat the solid waste generated during the construction process, the solid waste is first poured into the crushing box 1. At this time, the belt drive assembly 31 is connected to the active rod 43, and the active rod 43 generates continuous and stable rotational power through transmission, thereby driving the power assembly to start. The driven block 454 will slide along the set trajectory in the first guide hole 441, while driving the second crank 453 to swing. As the second crank 453 continues to swing, the connected second rotating rod 452 also begins to rotate synchronously. During the rotation process, the second rotating rod 452 drives the connected sliding block 451 to perform a fan-shaped motion together, and acts on the first movable rod 45 to cause it to swing in a follow-up manner. Since an elastic linkage structure is formed between the sliding block 451 and the first spring 47, the first spring 47 will stretch and compress during the sliding process, providing energy storage and rebound force for subsequent actions.

[0039] Under the action of elastic force, the sliding sleeve 491 slides rapidly on the surface of the first slide bar 42, thereby driving the position of the crushing knife 481 to change. In addition, relative sliding occurs between the lifting frame 48 and the second movable rod 49. When the first movable rod 45 swings under the drive of the sliding block 451, the second movable rod 49 will also slide synchronously in a straight line, and continue to provide guiding support after moving to the end position of the first slide bar 42. At this time, due to the continuous swinging of the first movable rod 45, the lifting frame 48 will slide up and down on the surface of the second movable rod 49, realizing a lifting action, which helps to accurately adjust the crushing position. Finally, the lifting frame 48 drives the crushing knife 481 to move up and down or forward and backward, which can assist in the impact crushing of larger solid waste, and can also apply extrusion force so that the solid waste can be in close contact with the crushing components inside the crushing box 1 to ensure normal crushing.

[0040] When the solid waste falls into the screening box 59, the third crank 54 is powered by the universal joint 6, which transmits power to the third crank 54, causing it to continue to move in a circular motion. This motion is then transmitted to the drive rod 55, causing it to reciprocate, and in turn, driving the second moving block 56 to move back and forth linearly within the first sliding slot 51.

[0041] The first movable block 53, coaxially connected to the third crank 54, slides freely within the first sliding slot 51. As the drive rod 55 reciprocates, it experiences a reaction force in the opposite direction of its motion. This reaction force propels the first movable block 53 to move synchronously within the sliding slot, ultimately causing the sorting assembly to vibrate and drive the screening box 59 to perform the screening operation.

[0042] Continuous operation eliminates the multiple loading and unloading steps required in traditional processes, improving material handling efficiency. Furthermore, the vibration screening process significantly reduces material accumulation and screen clogging, providing stable, pure raw materials for subsequent solid waste resource utilization or harmless treatment, effectively improving the overall efficiency of solid waste treatment.

[0043] Example 2: Figure 3 - Figure 5 As shown, the power assembly includes a swing rod 44 rotatably connected to the bottom end of the first fixed frame 41, a first guide hole 441 is opened at the top of the swing rod 44, a second guide hole 442 is opened at the bottom end of the swing rod 44, an active block 432 is slidably connected inside the second guide hole 442, the side wall of the active block 432 is rotatably connected to the first crank 431, the other end of the first crank 431 is fixedly connected to the active rod 43, and the active rod 43 is rotatably connected to the middle part of the first fixed frame 41.

[0044] In this embodiment, the second drive motor 3 drives the belt drive assembly 31 in a circular motion, which in turn drives the active rod 43 to rotate, thereby driving the first crank 431 connected thereto. Because the first crank 431 is provided with an active block 432 at one end, as it moves in a circular motion around the center of the active rod 43, the active block 432 slides along the inner wall of the second guide hole 442, exerting a continuous thrust on the swing rod 44.

[0045] Under the action of this driving force, the swinging rod 44 begins to swing back and forth at a certain angle, and exerts a force on the driven block 454 in contact with it through the first guide hole 441 provided thereon. This causes the crushing assembly to operate rapidly, and the crushing assembly begins to move left and right and up and down. The crushing assembly's movement and the weight of the crushing blade 481 installed at the bottom of the lifting frame 48 begin to strike the solid waste, thereby impacting the continuously sliding solid waste and breaking it. Afterwards, the crushing mechanism 4 performs a secondary crushing to improve the crushing effect, so that the finer the solid waste is, the better for the subsequent screening process.

[0046] When performing the crushing operation, the crushing knife 481 can evenly impact the solid waste in the crushing box 1, thereby effectively avoiding the material accumulation or jamming problems caused by the increase in the number of crushing equipment, ensuring the continuity of the crushing process and the smoothness of material loading, and at the same time improving the overall crushing efficiency and refinement effect.

[0047] Example 3: According to Figure 7 - Figure 10As shown, the sorting assembly includes a moving plate 531 and a shaking frame 561, both of which are slidingly connected with the second sliding groove 521 opened at the top of the base 52, the bottom of the moving plate 531 is fixedly connected with the top of the first moving block 53, the top of the moving plate 531 is fixedly connected with a receiving tray 532, the bottom of the shaking frame 561 is fixedly connected with the second moving block 56, and the top of the shaking frame 561 is fixedly connected with the screening box 59. The first sliding groove 51 is opened at the top of both sides of the base 52, the first moving block 53 and the second moving block 56 are both fixedly connected with the limiting rod 58 on the inner wall of the first sliding groove 51, the first moving block 53 and the second moving block 56 are both abutted with the second spring 57, and the two ends of the second spring 57 are sleeved on the outer surface of the limiting rod 58. The first moving block 53 is installed with the universal joint 6, and the third crank 54 is fixedly connected at one end of the universal joint 6. The screening box 59 is fixedly connected with the second fixed frame 591 on both sides, one of the second fixed frames 591 is fixedly connected with the second sliding rod 593 on the inner side, and the other side of the second fixed frame 591 is installed with the air cylinder 594. The movable sieve plate 592 is arranged below the screening box 59, the movable sieve plate 592 is slidingly connected with the second sliding rod 593 on one side of the top end, and the other side of the top end of the movable sieve plate 592 is fixedly connected with the output end of the air cylinder 594.

[0048] In this embodiment, during the process of solid waste screening, the belt drive assembly 31 transmits power to the universal joint 6, and then drives the sorting assembly to start moving, which is synchronized with the preliminary crushing process, improving the consistency of the overall processing. In addition, the middle part of the universal joint 6 has scalability, which can move synchronously with the first moving block 53, ensuring stable power transmission. While the first moving block 53 drives the moving plate 531 to move linearly, the second moving block 56 also drives the shaking frame 561 to reciprocate horizontally. At this time, the relative movement between the shaking frame 561 and the moving plate 531 can be effectively limited by the second sliding groove 521 to avoid jamming due to deviation, and the structure operation coordination and reliability are improved. Moreover, the limiting rod 58 is provided for stroke limitation to avoid the second spring 57 from being skewed during extension and contraction, and the elastic action of the second spring 57 enhances the buffering and rebounding capacity during movement.

[0049] Finally, with the linkage operation of the shaking frame 561 and the moving plate 531, the screening box 59 above and the receiving tray 532 also realize synchronous vibration or oscillation, so as to form a rhythmic screening and discharging action in the process of sorting and collecting after material crushing. This design not only improves the screening effect and can efficiently distinguish solid waste fragments of different particle sizes, but also effectively avoids problems such as blockage and accumulation of materials

[0050] The screened particle size can be flexibly adjusted based on the particle size requirements of different solid waste types to meet the needs of subsequent processing. Specifically, by controlling the extension and retraction of cylinder 594, the movable screen plate 592 can be precisely moved along a predetermined trajectory. Furthermore, the movable screen plate 592 can slide smoothly on the surface of the second slide bar 593, ensuring the stability and reliability of the overall screening operation.

[0051] The movement of the movable sieve plate 592 causes the holes on its surface to intersect or align with the holes on the surface of the screening box 59, thereby adjusting the size of the solid waste screening, so that the solid waste fragments are gradually dropped into the receiving tray 532 according to the particle size. The plate hingedly mounted on one side of the receiving tray 532 then receives the particles. If the formed holes are no longer able to sort the particles that meet the requirements, the size of the through-holes formed by the movable sieve plate 592 and the screening box 59 is gradually adjusted, so that the solid waste particles are classified and collected according to size, thus completing the intelligent sorting of solid waste.

[0052] Example 4: According to Figure 2 As shown, a first drive motor 11 is installed on one side of the crushing box 1, and the output end of the first drive motor 11 is fixedly connected to one of the first rotating rods 13. The outer surfaces of the two first rotating rods 13 are fixedly connected to gears 14, and the two gears 14 are meshed and connected. A side knife 12 is fixedly connected to the inside of the crushing box 1, and a crushing knife 15 is fixedly connected to the outer surface of the middle part of the first rotating rod 13. The crushing knife 15 and the side knife 12 are staggered with each other.

[0053] In this embodiment, after the initial solid waste screening is complete, the secondary crushing process begins. This process begins when the first drive motor 11 drives one of the first rotating rods 13 to rotate. This first rotating rod 13 transmits power via a connected gear 14, thereby driving the connected gear 14 to rotate synchronously. Because the two gears 14 are meshed, the rotation of one gear 14 drives the other gear 14 in the opposite direction, further rotating the other first rotating rod 13. This interlocking transmission mechanism of the gears 14 enables the two first rotating rods 13 to maintain synchronous rotation.

[0054] During rotation, the two first rotating rods 13 utilize the crushing blades 15 on their surfaces to clamp and shear the solid waste, further crushing the initially crushed solid waste. Simultaneously, the side blades 12 located on either side of the crushing area assist in cutting and separating the solid waste. The synergistic effect between the side blades 12 and the crushing blades 15 on the surfaces of the first rotating rods 13 effectively increases the crushing range and processing efficiency, resulting in a smaller and more uniform particle size after secondary processing, facilitating subsequent transportation, recycling, or incineration.

[0055] The method of use and working principle of this device: When processing solid waste during construction, the solid waste is first poured into the crushing box 1. By starting the second drive motor 3, the belt drive assembly 31 is driven to operate, driving the active rod 43 to rotate. The rotation of the active rod 43 will synchronously drive the first crank 431 to move, causing the active block 432 at the end of the first crank 431 to perform a circular motion with the active rod 43 as the center. During this process, the active block 432 will slide in the second guide hole 442 and apply a force to the swing rod 44, causing the swing rod 44 to swing. The swing rod 44 applies a force to the driven block 454 through the first guide hole 441, causing the driven block 454 to slide along the first guide hole 441 while driving the second crank 453 to rotate.

[0056] The rotation of the second crank 453 will drive the second rotating rod 452 to rotate synchronously, thereby driving the sliding block 451 to move. The movement of the sliding block 451 will cause the first movable rod 45 to rotate under the action of force, and at the same time provide expansion and contraction space for the first spring 47. Under the elastic action of the first spring 47, the sliding sleeve 491 slides rapidly along the surface of the first slide rod 42. As the first movable rod 45 continues to move, when the second movable rod 49 slides to the end of the first slide rod 42, the lifting frame 48 will slide up and down along the surface of the second movable rod 49, and finally drive the crushing knife 481 to realize left and right reciprocating and up and down compound motion, thereby crushing the larger solid waste fragments that continue to slide and cannot be crushed normally, so that they can enter the crushing box 1 normally for crushing. This motion trajectory design not only avoids the interference of the crushing equipment on the feed, but also ensures the crushing effect.

[0057] After the solid waste falls into the crushing box 1, the first drive motor 11 is started to rotate the first rotating rod 13. Through the meshing action of the gear 14, the two first rotating rods 13 rotate synchronously in opposite directions, and the crushing blades 15 on the surface cooperate with the side blades 12 to perform secondary crushing on the solid waste.

[0058] The crushed material falls into the screening box 59 for classification and screening. A cylinder 594 pushes the movable screen plate 592 to slide along the second slide bar 593. The holes in the movable screen plate 592 are then misaligned with the holes in the screening box 59, allowing for dynamic adjustment of the sieve aperture size, thereby controlling the size of the solid waste particles being screened.

[0059] During the screening process, the universal joint 6 rotates the third crank 54, which in turn drives the second movable block 56 in reciprocating motion via the drive rod 55. The movement of the second movable block 56 is transmitted via the second spring 57, causing the first movable block 53 to slide along the first sliding groove 51, thereby driving the synchronous movement of the movable plate 531 and the rocking frame 561. The second sliding groove 521 constrains the movement of the movable plate 531 and the rocking frame 561, ultimately achieving coordinated vibration between the screening box 59 and the receiving tray 532, significantly improving screening efficiency.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
