Description

Technical Field

[0001] This invention relates to the technical field of equipment for recycling and molding block waste, and more particularly to an energy-saving closed-loop recycling device for cutting waste from autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks, or simply AAC blocks, are lightweight, porous building materials produced through a multi-step process. They possess excellent physical and environmental properties. During the production of AAC blocks, large, cured blanks are cut into smaller blocks of specified sizes using steel wire. This cutting process inevitably produces fragments, powder, and defective products that do not meet size requirements.

[0003] Currently, most production lines typically collect waste materials after simple cleaning and then pile them up. Furthermore, the fragments and defective products after block cutting are often recycled through independent and intermittent processes, which involve collecting them separately, then transferring them, then crushing them, and finally re-blending them. This process is lengthy, results in high material loss, and leads to resource waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an energy-saving closed-loop recycling device for waste from the cutting of autoclaved aerated concrete blocks. This solves the problem mentioned in the background technology that the recycling process for fragments and defective products after block cutting is often independent and intermittent, resulting in lengthy processes, high material losses, and resource waste.

A first bevel gear is coaxially fixedly connected to the output end of the drive motor, and a second bevel gear is coaxially fixedly connected to the rotating shaft.

[0012] The carriage has an annular groove at one end near the mounting base. The mounting base is fixedly connected to a plurality of limiting posts corresponding to the annular groove, and the plurality of limiting posts are all limited and set in the annular groove.

[0013] Furthermore, a hydraulic rod is fixedly installed on the carriage, the hydraulic rod is arranged parallel to the inclined chute, and a pusher plate is fixedly connected to the output end of the hydraulic rod, the pusher plate being arranged on the inclined chute.

[0014] Furthermore, the molding part includes:

[0015] A feed hopper is fixedly installed on the mounting frame. The feed hopper is equipped with multiple crushing rollers and agitators. A fixed frame is provided below the feed hopper. A through hole is opened on the fixed frame. The fixed frame is fixedly connected to the mounting frame. A second hydraulic push rod is fixedly installed on the fixed frame. A baffle is fixedly connected to the output end of the second hydraulic push rod.

[0016] A movable frame is provided below the fixed frame, and a first hydraulic push rod is fixedly installed on the mounting bracket. The output end of the first hydraulic push rod is fixedly connected to the movable frame.

[0017] A third hydraulic push rod is provided at the end of the feed hopper away from the conveying mechanism. The third hydraulic push rod is fixedly installed on the mounting frame. A squeezing hammer is fixedly connected to the output end of the third hydraulic push rod. A lifting plate is provided below the squeezing hammer. A fourth hydraulic push rod is fixedly installed on the mounting frame. The output end of the fourth hydraulic push rod is fixedly connected to the lifting plate.

[0018] Furthermore, a set of guide rails is fixedly installed on the mounting bracket, and multiple limiting wheels are provided on the movable frame, with the multiple limiting wheels respectively limiting and positioned on a set of guide rails.

[0019] Furthermore, a guide frame is provided below the extrusion hammer, and multiple guide posts are provided on the outside of the guide frame.

[0021] Furthermore, the conveying mechanism includes: a conveyor belt inclinedly disposed on the feed hopper, a feed inlet provided at one end of the conveyor belt away from the feed hopper, and baffles provided on both sides of the conveyor belt.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention, through the cooperation of a transfer and recycling unit, a cutting mechanism, and a forming unit, recycles fragments and defective products, and reintroduces them as raw material components into the main production process, achieving zero discharge of solid waste at the production site and forming a complete material and energy closed loop of "forming-cutting-waste recycling-reforming", resulting in significant energy-saving and environmental protection benefits.

[0024] 2. This invention drives the first bevel gear and the second bevel gear to mesh and transmit power through the output end of the drive motor. The carriage rotates due to the cooperation of the rotating shaft, the annular groove and the limiting post, which facilitates the cutting of small blocks of the target size. This isolates the cutting mechanism and the carriage from the outside world, preventing the fragments of the blocks from jumping out during the cutting process. The fragments enter the inclined groove at the bottom of the carriage through the grating plate. Defective products enter the inclined groove at the bottom of the carriage through the through holes on both sides of the grating plate. Furthermore, the waste material is recycled during the cutting and forming process, making it easy to use directly.

[0025] 3. This invention controls the opening and closing of the bottom of the feeding hopper through a second hydraulic push rod and a baffle. Particles and defective products in the hopper are crushed and stirred by a crushing roller, then enter the moving frame. The output end of the third hydraulic push rod drives the extrusion hammer to initially extrude and demold the concrete material in the moving frame. Simultaneously, as the lifting plate descends, the extrusion elastic element moves downwards. During this downward movement, the elastic element pushes a set of right-angle pull plates fixedly connected to the right-angle pull plates, pulling the formed blocks away from the lifting plate. When the forming section requires the lifting plate to work with the moving frame again, the lifting plate disengages from the elastic element, and the right-angle pull plates reset. The operation is simple and convenient, shortening the process time and improving production efficiency. Attached Figure Description

[0043] Please see Figures 1 to 9 As an embodiment of the present invention, this embodiment provides an energy-saving closed-loop recycling device for waste material from the cutting of autoclaved aerated concrete blocks, including: a gantry frame 1, a mounting frame 2, a transfer and recycling section 3, and a forming section 6. The gantry frame 1 and the mounting frame 2 are arranged in parallel. A cutting mechanism 11 is provided on the gantry frame 1. A rail is provided below the gantry frame 1, and a carriage 33 is provided on the rail. Blocks 4 are placed inside the carriage 33.

[0044] The mounting frame 2 is equipped with a conveying mechanism 5, which includes a conveyor belt 52 inclined on the feed hopper 61, with a feed inlet 51 at the end of the conveyor belt 52 away from the feed hopper 61. Baffles are provided on both sides of the conveyor belt 52.

[0045] Usage process: First, the block 4 is moved to the cutting mechanism 11 through the transfer and recycling unit 3 and cut. After cutting, the qualified small blocks 4 are moved to the stacking area. The fragments and defective products from the cutting process are conveyed to the molding unit 6 through the conveying mechanism 5. The fragments and defective products from the cutting process are mixed with the raw materials and then subjected to preliminary extrusion molding. The molded blocks 4 are then demolded and then subjected to steam pressurization treatment to achieve a complete material and energy closed loop of "molding-cutting-waste recycling-remolding".

[0046] Please see Figures 3 to 5 The transfer and recycling unit 3 is set on the rail. The transfer and recycling unit 3 includes an installation base 31 for conveniently recycling the fragments and defective products after the blocks 4 are cut. The transfer and recycling unit 3 also includes: a grating plate 333 set in the carriage 33, the blocks 4 are placed on the grating plate 333, and a sloping groove is provided below the grating plate 333. The installation base 31 is provided with multiple moving wheels 32, which are set on the rail. The carriage 33 is set on the installation base 31, and a slag discharge plate 334 is rotatably connected to the carriage 33.

[0047] A hydraulic rod is fixedly installed on the carriage 33, and the hydraulic rod is arranged parallel to the inclined chute. A pusher plate is fixedly connected to the output end of the hydraulic rod, and the pusher plate is set on the inclined chute. A rotating shaft 332 is fixedly connected to the carriage 33, and the rotating shaft 332 is rotatably connected to the mounting base 31. A drive motor 34 is fixedly installed on the mounting base 31. A first bevel gear 341 is coaxially fixedly connected to the output end of the drive motor 34. A second bevel gear 35 is coaxially fixedly connected to the rotating shaft 332. The first bevel gear 341 and the second bevel gear 35 mesh and transmit power.

[0048] The carriage 33 has an annular groove 331 at one end near the mounting base 31. The mounting base 31 is fixedly connected to a plurality of limiting posts 311 corresponding to the annular groove 331. The plurality of limiting posts 311 are all limited and set in the annular groove 331.

[0049] Operating procedure: The block 4 is moved to the underside of the cutting mechanism 11 via the rails and the block 4 is cut. After the initial cutting is completed, the output end of the drive motor 34 drives the first bevel gear 341 and the second bevel gear 35 to mesh and transmit power, so that the carriage 33 rotates 90 degrees, which facilitates the cutting of small blocks 4 of the target size. During this process, the cutting mechanism 11 and the carriage 33 are isolated from the outside world to prevent the fragments of the block 4 from jumping out during the cutting process. The fragments enter the inclined groove at the bottom of the carriage 33 through the grating plate 333.

[0050] The mounting base 31 moves the cut small blocks 4 to the stacking area via the rails, collects and stacks the qualified small blocks 4, and the unqualified defective products enter the inclined groove at the bottom of the carriage 33 through the through holes on both sides of the grating plate 333. During the process of resetting to the cutting mechanism 11, the mounting base 31 passes through the feed inlet 51 of the conveying mechanism 5, and pushes the fragments and unqualified defective products on the inclined groove into the feed inlet 51 by the pusher plate, so as to facilitate the direct recycling of fragments and unqualified defective products.

[0051] Please see Figures 6 to 9 The forming part 6 is mounted on the mounting frame 2. The forming part 6 is used to shorten the forming process time of fragments, defective products and raw materials. The forming part 6 includes: a feeding hopper 61 fixedly mounted on the mounting frame 2. The feeding hopper 61 is provided with multiple crushing rollers 62 and a mixer. A fixing frame 64 is provided below the feeding hopper 61. The fixing frame 64 has a through hole and is fixedly connected to the mounting frame 2. A second hydraulic push rod 641 is fixedly mounted on the fixing frame 64. A baffle 642 is fixedly connected to the output end of the second hydraulic push rod 641.

[0052] A movable frame 63 is provided below the fixed frame 64, and a first hydraulic push rod 631 is fixedly installed on the mounting bracket 2. The output end of the first hydraulic push rod 631 is fixedly connected to the movable frame 63.

[0053] A third hydraulic push rod 65 is provided at the end of the feed hopper 61 away from the conveying mechanism 5. The third hydraulic push rod 65 is fixedly installed on the mounting frame 2. The output end of the third hydraulic push rod 65 is fixedly connected to the extrusion hammer 66. A lifting plate 69 is provided below the extrusion hammer 66. A fourth hydraulic push rod 68 is fixedly installed on the mounting frame 2. The output end of the fourth hydraulic push rod 68 is fixedly connected to the lifting plate 69.

[0054] A set of guide rails 632 is fixedly installed on the mounting frame 2. Multiple limit wheels 633 are provided on the moving frame 63. The multiple limit wheels 633 are respectively limited on the set of guide rails 632. A guide frame is provided below the extrusion hammer 66. Multiple guide posts are provided on the outside of the guide frame. The multiple guide posts and the guide frame are all fixedly connected to the mounting frame 2. The lifting plate 69 is provided below the guide frame. An installation plate is fixedly installed on the extrusion hammer 66. The lifting plate 69 and the installation plate are slidably connected to the guide posts. A limit baffle 67 is fixedly connected to the end of the guide frame away from the moving frame 63. A set of right-angle pull plates 691 is provided on the lifting plate 69.

[0055] Usage process: First, it is conveyed to the forming section 6 by the conveyor belt 52. Then, the second hydraulic push rod 641 blocks the bottom of the baffle 642 and the feed hopper 61. The broken particles and defective products entering the feed hopper 61 are crushed and stirred by the crushing roller 62. After stirring, the baffle 642 is opened and it enters the moving frame 63. The moving frame 63 is moved to the lifting plate 69 by the output end of the first hydraulic push rod 631. Then, the extrusion hammer 66 is driven by the output end of the third hydraulic push rod 65 to perform preliminary extrusion molding of the concrete raw materials in the moving frame 63.

[0056] After block 4 is formed, the lifting plate 69 is lowered by the fourth hydraulic push rod 68. The extrusion hammer 66 demolds the block 4 formed in the moving frame 63. At the same time, during the descent of the lifting plate 69, the elastic element is extruded and moves downward. During the downward movement of the elastic element, a set of right-angle pull plates 691 fixedly connected to the right-angle pull plates 691 are pushed to pull the formed block 4 away from the lifting plate 69. When the forming part needs the lifting plate 69 to work with the moving frame again, the lifting plate 69 disengages from the elastic element, and the right-angle pull plates 691 are reset. The demolded block 4 is then subjected to steam pressurization treatment. After the treatment is completed, the block 4 is moved to the cutting mechanism 11 through the transfer and recycling part 3. The fragments and defective products are recycled and re-enter the main production process as raw material components, realizing zero discharge of solid waste on the production site and forming a complete material and energy closed loop of "forming-cutting-waste recycling-reforming", with significant energy-saving and environmental protection benefits.

[0057] As can be seen from the above, the working principle of this application is as follows:

[0058] First, by placing the block 4 into the carriage 33, the block 4 is moved to the underside of the cutting mechanism 11 via the rails and cut. After the initial cutting is completed, the output end of the drive motor 34 drives the first bevel gear 341 and the second bevel gear 35 to mesh and transmit power, so that the carriage 33 rotates 90 degrees, which makes it easier to cut out small blocks 4 of the target size. During this process, the cutting mechanism 11 and the carriage 33 are isolated from the outside world.

[0059] The mounting base 31 moves the cut small blocks 4 to the stacking area via the rails, collects and stacks the qualified small blocks 4, and the unqualified defective products enter the inclined groove at the bottom of the carriage 33 through the through holes on both sides of the grating plate 333. During the process of resetting to the cutting mechanism 11, the mounting base 31 passes through the feed inlet 51 of the conveying mechanism 5, and pushes the fragments and unqualified defective products on the inclined groove into the feed inlet 51 by the pusher plate, and then conveys them to the forming section 6 by the conveyor belt 52.

[0060] The second hydraulic push rod 641 blocks the baffle 642 and the bottom of the feed hopper 61. The broken particles and defective products entering the feed hopper 61 are crushed and mixed by the crushing roller 62. After the mixing is completed, the baffle 642 is opened and the material enters the moving frame 63. The moving frame 63 is moved to the lifting plate 69 by the output end of the first hydraulic push rod 631. Then, the extrusion hammer 66 is driven by the output end of the third hydraulic push rod 65 to perform preliminary extrusion molding of the concrete raw material in the moving frame 63.

[0061] After the block 4 is formed, the lifting plate 69 is lowered by the fourth hydraulic push rod 68, and the extrusion hammer 66 demolds the block 4 formed in the moving frame 63. After demolding, the block 4 is then subjected to steam pressurization treatment. After the treatment is completed, the block 4 is moved to the cutting mechanism 11 through the transfer and recycling unit 3. The fragments and unqualified defective products are recycled and re-enter the main production process as raw material components.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
