Description

Technical Field

[0001] This utility model relates to the field of waste resource utilization, and in particular to an integrated equipment for recycling construction waste into bricks. Background Technology

[0002] Construction waste refers to solid waste generated during construction, demolition, and renovation. It mainly includes concrete blocks, bricks, mortar, waste stone, and some metal and wood components. With the acceleration of urbanization, the amount of construction waste generated continues to increase. If not properly treated, it will not only occupy a large amount of land resources but also cause environmental pollution.

[0003] Existing construction waste processing equipment mainly focuses on crushing and screening, breaking down waste into recycled aggregates of a certain particle size for use in recycled concrete or road base materials. However, these types of equipment are generally structurally dispersed, requiring separate crushing, screening, batching, and molding operations, resulting in complex processes, large footprints, high energy consumption, and low material transfer efficiency between different pieces of equipment.

[0004] Existing equipment fails to achieve efficient integrated processing of construction waste, resulting in low utilization rates of recycled raw materials and poor brick-making efficiency, making it difficult to meet the requirements of energy conservation, environmental protection, and resource recycling. Therefore, there is a need for an integrated device that can perform crushing, screening, batching, and molding functions to improve the efficiency of recycled brick production from construction waste and enhance equipment integration. Utility Model Content

[0011] Preferably, a support plate is fixedly connected between the support legs, and a spring is fixedly connected between the support plate and the connecting plate.

[0012] Preferably, the extrusion mechanism includes a conveying pipe fixedly connected to the inside of the support leg, one end of the conveying pipe being rotatably connected to a third rotating shaft, and a spiral blade being fixedly connected to a section of the third rotating shaft located inside the conveying pipe.

[0016] Beneficial effects: This utility model realizes a continuous integrated processing flow of crushing, screening, extrusion molding and fixed-length cutting of construction waste by sequentially setting crushing mechanism, screening mechanism, extrusion molding and cutting components on the same support structure. It reduces the transfer links of materials between independent equipment, significantly shortens the brick making process, and improves the level of production automation and brick making efficiency.

[0017] Furthermore, the crushing mechanism employs a dual-shaft, dual-gear transmission structure, enabling bidirectional shearing and crushing of construction waste with high efficiency and uniform particle size. The screening mechanism is equipped with a vibrator and springs, achieving efficient screening while mitigating vibration impact and ensuring equipment operational stability. The extrusion mechanism uses spiral blades to continuously push materials into the extrusion tube for compaction and shaping, resulting in high-density billets. The cutting assembly uses a cylinder-driven cutter for reciprocating cutting, coupled with a conveyor belt for automatic fixed-length cutting and output, facilitating subsequent handling and maintenance. In summary, the structural design results in a small footprint, simple operation, and high resource utilization, making it highly valuable for industrial application. Attached Figure Description

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 4 As shown in the figure, an integrated brick-making equipment for recycled construction waste provided by this utility model includes a support structure 100, a crushing mechanism 200 disposed on the support structure 100, a screening mechanism 300 disposed at the lower end of the crushing mechanism 200, an extrusion mechanism 400 disposed below the screening mechanism 300, and a cutting component 500 disposed at the end of the extrusion mechanism 400. This structure enables construction waste to undergo crushing, screening, extrusion, and cutting processes sequentially, realizing automated continuous brick-making and improving the recycling rate of waste.

[0022] The support structure 100 includes a base 101, with four support legs 102 on one side of the base 101. A first bracket 105 is provided on the top side of each support leg 102, and a second bracket 106 is fixedly connected to the lower side. A support frame 104 is provided on the other side of the base 101, and a support block 103 is provided on the right side of the support frame 104. The base 101 and the support legs 102 provide a load-bearing and stable foundation for the equipment. The first bracket 105 and the second bracket 106 are used for subsequent motor installation support. The support frame 104 and the support block 103 provide an installation platform for the subsequent cutting assembly 500.

[0023] The crushing mechanism 200 includes a crushing chamber 205 with a feed inlet 204 at its upper opening. The crushing chamber 205 is fixedly connected to the top of the support leg 102, and a first discharge outlet 210 is provided at its bottom. A first rotating shaft 209 and a second rotating shaft 208, arranged in parallel, pass through the crushing chamber 205. A drive roller 202 is sleeved on the first rotating shaft 209, and a driven roller 203 is sleeved on the second rotating shaft 208. A first motor 201 is fixedly connected to one end of the first rotating shaft 209, and the output shaft of the first motor 201 is fixedly connected to the first rotating shaft 209. A first bracket 105 is fixedly connected to the side of the top of the support leg 102, and the first motor 201 is fixedly connected to the first bracket 105. A first gear 206 is fixedly connected to the end of the first rotating shaft 209 near the first motor 201, and a second gear 207 is fixedly connected to the second rotating shaft 208, meshing with the first gear 206. The dual-shaft structure, combined with dual gears, enables synchronous reverse rotation, thereby performing bidirectional shearing and crushing of construction waste entering the crushing chamber 205. This design effectively reduces material blockage and improves crushing efficiency and particle uniformity.

[0024] The screening mechanism 300 includes a screening chamber 301 with a second discharge port 307 at its lower opening. A screen 302 is installed inside the screening chamber 301, and the upper opening of the screening chamber 301 covers the discharge range of the first discharge port 210. A vibrator 303 is fixedly connected to the side wall of the screening chamber 301, and a connecting plate 304 is fixedly connected to the side wall. A support plate 306 is fixedly connected between the support legs 102, and a spring 305 is fixedly connected between the support plate 306 and the connecting plate 304. The crushed material enters the screening chamber 301 through the first discharge port 210 and is screened by the screen 302 under the drive of the vibrator 303. The spring 305 provides flexible support to absorb vibration impact and prevent structural resonance between the screening chamber 301 and the support structure 100, thereby ensuring screening stability and service life.

[0025] The extrusion mechanism 400 includes a conveying pipe 404, which is fixedly connected to the inner side of the support leg 102. The second discharge port 307 is fixedly connected to the conveying pipe 404. A third rotating shaft 402 is rotatably connected to one end of the conveying pipe 404. A second motor 401 is arranged beside the third rotating shaft 402 and is fixedly connected to the second bracket 106. The output shaft of the second motor 401 is fixedly connected to the third rotating shaft 402. A spiral blade 403 is fixedly connected to a section of the third rotating shaft 402 located inside the conveying pipe 404. An extrusion tube 405 is fixedly connected to the end of the conveying pipe 404. The second motor 401 drives the third rotating shaft 402 to rotate, and the spiral blade 403 pushes the sieved fine material along the conveying pipe 404 into the extrusion tube 405, forming a high-pressure extrusion effect in a closed space. This structure can improve the density of the billet and prevent material backflow, thus improving molding consistency.

[0026] The cutting assembly 500 includes a cylinder 502, which is fixedly connected to the support frame 104. A connecting rod 503 is fixedly connected to the piston rod of the cylinder 502, and a cutter 501 is fixedly connected to the other end of the connecting rod 503. A conveyor belt 504 is disposed below the cutter 501, and the bottom of the conveyor belt 504 is fixedly connected to the support block 103. The cylinder 502 provides a linear driving force, causing the cutter 501 to reciprocate up and down, cutting the continuously extruded bricks to a fixed length. The conveyor belt 504 ensures the smooth output of the cut bricks, providing a connection for subsequent handling and drying processes.

[0027] Working principle: such as Figures 1 to 4As shown, when the equipment starts, construction waste is fed into the crushing mechanism 200 via the feeding device. The first motor 201 drives the first rotating shaft 209 to rotate, and through the meshing of the first gear 206 and the second gear 207, the second rotating shaft 208 rotates synchronously. The two rotating shafts drive the crushing teeth installed on their surfaces to shear and crush the waste, thereby achieving the crushing of large pieces of construction waste. The crushed material falls into the screening mechanism 300 through the first discharge port 210.

[0028] In the screening mechanism 300, the screen 302 in the screening chamber 301 classifies the crushed material by particle size; the vibrator 303 generates vibration, so that the material is evenly distributed on the screen surface and achieves efficient screening. The qualified particles under the screen fall into the extrusion mechanism 400 below through the bottom of the screening chamber 301.

[0029] The second motor 401 drives the third rotating shaft 402 to rotate, which in turn drives the spiral blades 403 in the conveying pipe 404 to continuously push the screened material into the extrusion pipe 405. During the spiral propulsion process, the material is compacted and formed into a long strip of mud, which is then conveyed to the cutting component 500 at the end of the extrusion mechanism 400.

[0030] In the cutting assembly 500, the piston rod of the cylinder 502 reciprocates under the action of the control system, driving the connecting rod 503 to push the cutter 501 up and down to cut the extruded clay blank into brick blanks of specified size. The cut brick blanks fall onto the conveyor belt 504 and are transported by the conveyor belt 504 to the subsequent curing or stacking position.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
