Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling and treatment, and in particular to a construction waste recycled aggregate treatment device. Background Art

[0002] Recycled aggregate is new concrete made by crushing, cleaning and grading discarded concrete blocks, mixing them with grading in a certain proportion, and then adding ingredients such as cement and water. With the development of urbanization, the renovation and renewal of old buildings and facilities is accelerating, and the recycling and utilization of construction waste is also developing.

[0003] When construction waste is recycled into aggregate, the concrete blocks in the construction waste will be crushed and sorted. However, the concrete blocks will be subjected to continuous impact in the process of being crushed into recycled aggregate. The damage of the concrete blocks in the process of disintegration and crushing will accumulate, resulting in more tiny cracks inside the recycled aggregate, which makes the strength of the recycled aggregate lower than that of conventional sand and gravel aggregate, resulting in the overall strength of the new concrete made of recycled aggregate being lower than that of the concrete made of normal sand and gravel aggregate, and unable to meet the use requirements of some construction facilities. In addition, various parts of the concrete blocks in the construction waste will be damaged by irregular forces during the crushing process, resulting in the recycled aggregate obtained by crushing having more edges and corners, which results in a larger gap rate in the new concrete cast with the recycled aggregate later, affecting the overall quality of the new concrete made of the recycled aggregate.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1, refer to Figure 1-Figure 8 , a construction waste recycled aggregate processing equipment, including a processing seat 1 and a jaw crusher mechanism 2 for preliminary crushing of concrete blocks, a processing motor 5 is arranged above the processing seat 1, the output end of the processing motor 5 is connected to a driving gear 6 through a driving shaft, a heat mixing component is arranged on one side of the driving gear 6, and a heating box 13 is arranged below the heat mixing component;

[0030] Furthermore, four traveling wheels 3 are rotatably connected to the bottom end of the processing seat 1, the output end of the processing motor 5 is connected to the jaw crushing mechanism 2 through a driving shaft, a hopper 4 is arranged outside the jaw crushing mechanism 2, and a heat mixing assembly is composed of a heat mixing gear 7 and a pushing gear 8, the heat mixing gear 7 and the pushing gear 8 are meshed with each other, a plurality of heat mixing rods 10 are fixedly connected to the end of the heat mixing gear 7 through a rotating shaft, a plurality of pushing arc plates 9 are fixedly connected to the end of the pushing gear 8 through a rotating shaft, the driving gear 6 is meshed with the heat mixing gear 7, a heat mixing box 11 is arranged below the jaw crushing mechanism 2, an inclined plate 12 is fixedly connected to the inner side wall of the heat mixing box 11, the bottom end of the heat mixing box 11 is fixedly connected to the top end of the heating box 13, the bottom end of the heating box 13 is fixedly connected to the top end of the processing seat 1, a discharge hole is opened at the end of the heat mixing box 11, a plurality of heat preservation curtains 14 are fixedly connected to the inner side wall of the discharge hole, and a sliding arc plate 15 is fixedly connected to the end of the heat mixing box 11;

[0031] It should be noted that: the recycling and processing device is driven to the pile of construction waste by the traveling wheel 3, and then the waste concrete blocks are put into the feed hopper 4 on the processing seat 1 by the excavator. The concrete blocks are disintegrated and crushed under the extrusion and impact of the jaw crusher 2 to obtain preliminary crushed aggregates with larger particle size. The preliminary crushed aggregates will enter the mixing box 11 through the feed hopper 4, fall on the inclined plate 12 and slide to the side of the push arc plate 9. During the preliminary crushing process, the processing motor 5 is in operation, and the processing motor 5 will drive the driving gear 6 to rotate through the driving shaft, thereby driving the processing motor 5 to rotate the driving gear 6 and ... The dynamic heat mixing gear 7 and the pushing gear 8 rotate, and the pushing gear 8 rotates to drive the multiple pushing arc plates 9 to rotate toward the cooling cylinder 16 to push the preliminary crushed aggregate outward. The heat mixing gear 7 rotates to drive the multiple staggered heat mixing rods 10 to rotate, and continuously adjust the contact surface between the preliminary crushed aggregate and the bottom of the heat mixing box 11. At the same time, the heating box 13 continuously heats the heat mixing box 11, so that the preliminary crushed aggregate in the heat mixing box 11 is heated during the movement. After the heating is completed, the preliminary crushed aggregate will be continuously squeezed out and fall into the cooling cylinder 16 through the sliding arc plate 15.

[0032] A further advantage of adopting the above method is that the discarded concrete blocks can be initially crushed into initial crushed aggregates with larger particle sizes, and the initial crushed aggregates are heated by the mixing box 11 so that they have a higher temperature, which is convenient for subsequent amplification of small cracks in the initial crushed aggregates by thermal expansion and contraction.

[0033] Example 2, reference Figure 1-Figure 8 A cooling cylinder 16 is disposed outside the heating box 13, a screw-out assembly is disposed inside the cooling cylinder 16, and cooling water is disposed inside the cooling cylinder 16;

[0034] Furthermore, the unscrewing assembly is composed of a rotating seat 18 and an unscrewing blade 19, the side wall of the processing seat 1 is fixedly connected with an unscrewing motor 17, the output end of the unscrewing motor 17 is fixedly connected to the bottom end of the unscrewing blade 19 through the rotating seat 18, the side wall of the processing seat 1 is fixedly connected to the outer wall of the cooling cylinder 16, the inner wall of the cooling cylinder 16 is rotatably connected to the side wall of the unscrewing blade 19, and a discharge groove is opened at the top of the cooling cylinder 16;

[0035] It should be noted that the preliminary crushed aggregates that fall into the cooling cylinder 16 will be in full contact with the cooling water in the cooling cylinder 16, and the concrete material will be deformed due to the principle of thermal expansion and contraction. At this time, the temperature difference between the internal temperature and the surface temperature of the concrete fragments of the preliminary crushed aggregates will be large, resulting in internal stress in the concrete of the preliminary crushed aggregates, thereby amplifying the tiny cracks in the preliminary crushed aggregates caused by the initial crushing impact, which also facilitates water to continuously penetrate into the cracks and reduce the strength of the preliminary crushed aggregates. The rotation of the rotary motor 17 will drive the rotary blade 19 to rotate through the rotary seat 18, and the preliminary crushed aggregates that fall on the rotary seat 18 will move to the edge side wall of the cooling cylinder 16 under the action of centrifugal force, and then be rolled up by the rotating rotary blade 19, and continuously transported upward to the discharge trough of the cooling cylinder 16 for discharge;

[0036] A further advantage of adopting the above method is that the surface of the heated primary crushed aggregate can be cooled, so that internal stress is generated inside the concrete of the primary crushed aggregate due to the temperature difference between the inside and the outside, and the tiny cracks in the primary crushed aggregate are enlarged. The cracks are then immersed in water, which makes it easier for the primary crushed aggregate to be crushed again along the cracks with less destructive force, thereby reducing the tiny cracks in the produced recycled aggregate and improving the overall strength of the recycled aggregate.

[0037] Example 3, reference Figure 1-Figure 8 A re-crushing bucket 20 is connected to the side wall of the processing seat 1, and a re-crushing motor 21 is arranged outside the re-crushing bucket 20. The re-crushing motor 21 is connected to two squeezing rollers 25 through a staggered gear assembly. A conveying sleeve 27 is arranged below the squeezing roller 25. A grinding spiral blade 26 is arranged in the conveying sleeve 27. A plurality of steel grinding beads are arranged in the grinding spiral blade 26. A magnetic disk 29 is arranged at the end of the grinding spiral blade 26;

[0038] Further, the side wall of the processing seat 1 is fixedly connected to the outer side wall of the composite crushing bucket 20, the end of the composite crushing bucket 20 is fixedly connected to the side wall of the composite crushing motor 21, the output end of the composite crushing motor 21 is fixedly connected to the inner side wall of the grinding spiral blade 26 through the grinding shaft, and the output end of the composite crushing motor 21 is fixedly connected to the inner side wall of the magnetic disk 29 through the grinding shaft. The staggered gear assembly consists of an outer gear 22, a transfer gear 23 and an inner gear 24. The outer gear 22 is meshed with the transfer gear 23, the transfer gear 23 is meshed with the inner gear 24, and the transfer gear 2 3 and the inner gear 24 are fixedly connected to the inner side walls of the two squeezing rollers 25 through two rotating shafts respectively, the grinding spiral blade 26 is arranged in an inclined manner in the re-breaking bucket 20, the outer side wall of the grinding spiral blade 26 is rotatably connected to the inner side wall of the conveying sleeve 27, the inner side wall of the re-breaking bucket 20 is fixedly connected to the outer side wall of the conveying sleeve 27, a sliding trough plate 28 is arranged below the conveying sleeve 27, a plurality of magnetic separation holes adapted to the grinding beads are opened on one end of the magnetic disk 29, and the inner side wall of the re-breaking bucket 20 is slidably connected to the other end of the magnetic disk 29 through a baffle 30;

[0039] It should be noted that the initially crushed aggregate discharged from the cooling cylinder 16 will enter the re-crushing bucket 20. Before that, the re-crushing motor 21 is started to drive the outer gear 22 to rotate. The rotation of the outer gear 22 will drive the thicker transfer gear 23 to rotate. The transfer gear 23 rotates and then drives the inner gear 24 to rotate. The reverse rotation of the transfer gear 23 and the inner gear 24 will drive the two squeezing rollers 25 to rotate inward in opposite directions, and the initially crushed aggregate with enlarged micro cracks will be squeezed and crushed. The external destructive force on the initially crushed aggregate is small, and it is not easy to generate new micro cracks. The original initially crushed aggregate is crushed into recycled aggregate along the enlarged water-soaked cracks. The recycled aggregate after crushing again will fall into the upper outer wall of the conveying sleeve 27. The inclined setting makes the fallen recycled aggregate slide to the lower end of the upper outer wall of the conveying sleeve 27 under the action of its own gravity, so that the recycled aggregate enters the grinding spiral blade 26 and is continuously mixed with a large number of grinding beads. During the conveying process in the grinding spiral blade 26, the recycled aggregate is squeezed and moved by the grinding beads to grind the relatively protruding edges and corners of the recycled aggregate. The recycled aggregate is conveyed to the higher end of the conveying sleeve 27 and falls into the sliding chute plate 28 from below, and slides downward again under the action of its own gravity. The start-up of the re-breaking motor 21 will drive the magnetic disk 29 to rotate together, and the grinding beads sliding in the sliding chute plate 28 will be continuously magnetically attracted to the magnetic separation hole by the magnetic disk 29. After the grinding beads rotate to the top, they will be squeezed by the baffle 30 on the other side, fall back to the top of the conveying sleeve 27 and enter the grinding spiral blade 26;

[0040] A further advantage of adopting the above method is that the protruding edges and corners of the re-crushed recycled aggregate can be polished by the flow extrusion method of the polishing beads, thereby reducing the damage to the recycled aggregate during the polishing process and avoiding excessive gaps between the produced recycled aggregates when they are used.

[0041] When the present invention is in use, the traveling wheel 3 is used to drive the recycling and processing device to the pile of construction waste, and then the waste concrete blocks are put into the feed hopper 4 on the processing seat 1 by the excavator. The concrete blocks are disintegrated and crushed under the extrusion and impact of the jaw crusher 2 to obtain preliminary crushed aggregates with larger particle size. The preliminary crushed aggregates will enter the mixing heat box 11 through the feed hopper 4, fall on the inclined plate 12 and slide toward the side of the pusher arc plate 9. During the preliminary crushing process, the processing motor 5 is in a running state, and the processing motor 5 will drive the driving gear 6 to rotate through the driving shaft, thereby driving the mixing heat gear 7 and the pusher gear 8 to rotate respectively. The rotation of the pusher gear 8 will drive multiple pusher arc plates 9 to rotate toward the side of the cooling cylinder 16. The preliminary crushed aggregate is pushed outward, and the rotation of the heat mixing gear 7 drives the rotation of the multiple staggered heat mixing rods 10, and the contact surface of the preliminary crushed aggregate with the bottom in the heat mixing box 11 is continuously adjusted. At the same time, the heating box 13 continuously heats the heat mixing box 11, so that the preliminary crushed aggregate in the heat mixing box 11 is heated during the movement. After the heating is completed, the preliminary crushed aggregate is continuously squeezed out and falls into the cooling cylinder 16 through the sliding arc plate 15. In this way, the discarded concrete blocks can be preliminarily crushed into preliminary crushed aggregates with larger particle sizes. The preliminary crushed aggregates are heated by the heat mixing box 11 so that they have a higher temperature, which is convenient for the subsequent enlargement of the tiny cracks in the preliminary crushed aggregates by the way of thermal expansion and contraction.

[0042] The initially crushed aggregates falling into the cooling cylinder 16 will be in full contact with the cooling water in the cooling cylinder 16, and the concrete material will be deformed due to the principle of thermal expansion and contraction. At this time, the temperature difference between the internal temperature and the surface temperature of the concrete fragments of the initially crushed aggregates will be large, resulting in internal stress in the concrete of the initially crushed aggregates, thereby amplifying the tiny cracks in the initially crushed aggregates caused by the initial crushing impact, which also makes it easier for water to continuously penetrate into the cracks, reducing the strength of the initially crushed aggregates. The rotation of the rotary motor 17 will drive the rotary blade 19 to rotate through the rotary seat 18, and fall onto the rotary seat 18. The initially crushed aggregate will move to the edge side wall of the cooling cylinder 16 under the action of centrifugal force, and then be drawn in by the rotating and unscrewing blades 19, and continuously transported upward to the discharge groove of the cooling cylinder 16 for discharge, so that the surface of the heated initially crushed aggregate can be cooled, so that the concrete inside the initially crushed aggregate generates internal stress due to the temperature difference between the inside and the outside, and the tiny cracks in the initially crushed aggregate are enlarged, and then the cracks are immersed in water, so that the initially crushed aggregate can be crushed along the cracks with less destructive force, thereby reducing the tiny cracks in the recycled aggregate and improving the overall strength of the recycled aggregate;

[0043] The initially crushed aggregate discharged from the cooling cylinder 16 will enter the re-crushing bucket 20. Before that, the re-crushing motor 21 is started to drive the outer gear 22 to rotate. The rotation of the outer gear 22 will drive the thicker transfer gear 23 to rotate. The transfer gear 23 rotates and then drives the inner gear 24 to rotate. The reverse rotation of the transfer gear 23 and the inner gear 24 will drive the two squeezing rollers 25 to rotate inward in opposite directions, and the initially crushed aggregate with enlarged micro cracks will be squeezed and crushed. The initial crushed aggregate will be subjected to less external destructive force, and it is not easy to produce new micro cracks. The original initially crushed aggregate is crushed into regenerated aggregate along the enlarged water-soaked cracks. The regenerated aggregate after re-crushing will fall into the upper outer wall of the conveying sleeve 27. Due to the overall inclined setting of the conveying sleeve 27, the grinding spiral blade 26 and the sliding trough plate 28, the fallen regenerated aggregate will slide to the lower end of the upper outer wall of the conveying sleeve 27 under the action of its own gravity, so that the regenerated aggregate The material enters the grinding spiral blade 26 and is continuously mixed with a large number of grinding beads. During the transportation process in the grinding spiral blade 26, it is squeezed and moved by the grinding beads to grind the relatively protruding edges and corners of the recycled aggregate. The recycled aggregate is transported to the higher end of the conveying sleeve 27 and falls into the sliding chute 28 from below, and slides downward again under the action of its own gravity. The start-up of the re-breaking motor 21 will drive the magnetic disk 29 to rotate together, and the grinding beads sliding in the sliding chute 28 will be continuously magnetically attracted to the magnetic separation holes by the magnetic disk 29. After the grinding beads rotate to the top, they will be squeezed by the baffle 30 on the other side, fall back into the top of the conveying sleeve 27 and enter the grinding spiral blade 26, so that the protruding edges and corners of the recycled aggregate after the second crushing can be subjected to the flow extrusion grinding of the grinding beads, thereby reducing the damage to the recycled aggregate during the grinding process and avoiding the situation where the gaps between the produced recycled aggregates are too large when they are used, resulting in a reduction in the strength of the recycled aggregate.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
