Description

Technical Field

[0001] This solution belongs to the technical field of carbonation equipment, specifically involving a carbonation device for recycled aggregates from solid waste used in concrete. Background Technology

[0002] Utility model patent CN221275663U discloses a carbonization treatment device for recycled aggregate, including a recycled aggregate feeding mechanism, a carbonization reactor, a calcium ion solution feeding mechanism, a stirring unit, and a carbon dioxide feeding mechanism. The carbonization reactor has a recycled aggregate inlet, a calcium ion solution inlet, a carbon dioxide inlet, a finished product outlet, and a liquid outlet. The stirring unit is set inside the carbonization reactor to form a stirring setup. The calcium ion solution feeding mechanism provides a calcium ion-rich solution and mixes it evenly with the recycled aggregate raw materials to increase the content of carbonizable substances. Subsequently, it is easier to undergo a carbonization reaction with carbon dioxide to form a calcium carbonate deposition layer on both the surface and internal structure of the recycled aggregate particles, filling the microcracks in the recycled aggregate particles themselves, and increasing the hardness of the recycled aggregate particles, thereby significantly improving the mechanical properties and durability of the recycled aggregate finished product.

[0003] However, the device has some shortcomings. The contact between the aggregate and carbon dioxide inside the device is not complete enough, resulting in uneven carbonization of the aggregate. At the same time, it is not convenient to discharge the aggregate from the carbonization tank. Utility Model Content

[0004] The purpose of this solution is to provide a carbonation device for recycled aggregates from solid waste used in concrete, in order to solve the problems of insufficient contact between aggregates and carbon dioxide inside the device, resulting in uneven carbonation of the aggregates, and the inconvenience of discharging the aggregates from the carbonation tank.

[0005] To achieve the above objectives, this solution provides a carbonation device for recycled aggregates from solid waste used in concrete, including a carbonation tank. A tank cover is fixedly installed at the upper end of the carbonation tank, and a feed hopper is fixedly connected inside the tank cover. A motor is fixedly installed at the middle of the upper end of the tank cover, and the motor shaft passes through the tank cover and is rotatably connected to the tank cover. A support pipe is fixedly connected to the lower end of the motor shaft, and an adjustment mechanism is provided on the support pipe. An end cap is threadedly connected to the lower end of the carbonation tank.

[0006] The principle of this solution is as follows: During use, aggregate is poured into the carbonization tank through the feed hopper, followed by the addition of water. The feed hopper is then sealed. Carbon dioxide is introduced into the support pipe via an air pump. The carbon dioxide in the support pipe enters the sliding tube and is discharged through the perforated tube. The motor is started, driving the support pipe to rotate, which in turn drives the sliding tube to rotate. The air pump continues to introduce carbon dioxide into the support pipe, and the motor-driven rotation of the support pipe further agitates the aggregate, resulting in a more uniform distribution of carbon dioxide within the aggregate. This process ensures more uniform and efficient aggregate carbonization. After the aggregate carbonization is completed in the carbonization tank, the motor and air pump stop working, allowing the aggregate to settle. Then, the cylinder is activated, driving the slide tube to slide outside the support tube. This causes the support ring to elastically press down on the slide ring, which in turn causes the slide ring to move the sealing plate down and contact the inner wall of the carbonization tank. This allows the sealing plate to seal the aggregate that has settled at the bottom of the carbonization tank. Then, the motor is activated to continuously drive the slide tube to rotate, which in turn causes the support shaft to rotate. The support shaft then drives the conveyor blade to rotate, making it easier for the aggregate to be discharged.

[0007] The technical advantages of this solution are as follows: carbon dioxide is introduced into the support pipe by an air pump, and the support pipe is driven to rotate by a motor, which in turn causes the slide pipe to drive the hollow pipe to rotate, thus stirring the aggregate. This allows the carbon dioxide to be distributed more evenly in the aggregate, resulting in more uniform and efficient carbonization of the aggregate.

[0008] The cylinder drives the sliding tube to slide outside the support tube, which in turn causes the support ring to elastically press down on the sliding ring. This causes the sliding ring to move the sealing plate down and contact the inner wall of the carbonization tank, allowing the sealing plate to seal the aggregate that has settled at the bottom of the carbonization tank. Furthermore, the rotating conveyor blade facilitates the discharge of the aggregate.

[0009] Furthermore, the adjusting mechanism includes an air pump, the air pump's inlet pipe passing through the can lid and fixedly connected to the can lid, a slide tube slidably connected to the outside of the support pipe, a turntable fixedly connected to the outside of the slide tube, a cylinder fixedly mounted on the upper end of the can lid, the cylinder rod of the cylinder passing through the can lid and slidably connected to the can lid, a perforated tube fixedly connected inside the slide tube, a support shaft fixedly connected to the lower end of the slide tube, a conveying knife fixedly connected to the outside of the support shaft, a support ring fixedly connected to the outside of the slide tube, a slip ring slidably connected to the outside of the slide tube, a spring provided on the outside of the slide tube, a sealing plate fixedly connected to the outside of the slip ring, and the sealing plate movably connected to the carbonization can. Carbon dioxide is introduced into the support pipe by an air pump, and the support pipe is driven to rotate by a motor. This, in turn, causes the sliding pipe to rotate, which in turn drives the perforated pipe to rotate, thus agitating the aggregate. This allows the carbon dioxide to be distributed more evenly within the aggregate, resulting in more uniform and efficient carbonization. The sliding pipe is driven by a cylinder to slide outside the support pipe, which in turn causes the support ring to elastically press down on the sliding ring. This causes the sliding ring to move the sealing plate down and into contact with the inner wall of the carbonization tank. This allows the sealing plate to seal the aggregate that has settled at the bottom of the carbonization tank. Furthermore, the rotating conveyor blade facilitates the discharge of the aggregate.

[0010] Furthermore, an annular groove is formed on the outer side of the support tube, and the annular groove is slidably connected to the air pump's inlet pipe. By providing the annular groove, the air pump's inlet pipe can slide within the support tube.

[0011] Furthermore, a baffle is fixedly connected to the outside of the air inlet pipe of the air pump, and the baffle is rotatably connected to the support pipe. The baffle seals the annular groove.

[0012] Furthermore, a guide block is fixedly connected inside the slide tube, and the guide block is slidably connected to the support tube. The guide block guides the movement of the slide tube.

[0013] Furthermore, a limit pin is fixedly connected to the surface of the cylinder rod, and the limit pin is slidably connected to the turntable. The limit pin guides the movement of the turntable.

[0014] Furthermore, one end of the spring is fixedly connected to the slip ring, and the other end of the spring is fixedly connected to the support ring. By setting the spring, the slip ring is elastically compressed. Attached Figure Description

[0021] The implementation examples are basically as follows Figure 1 , Figure 2 As shown, this embodiment provides a carbonation device for recycled aggregates from solid waste used in concrete, including a carbonation tank 1. A tank cover 2 is fixedly installed on the upper end of the carbonation tank 1. A feed hopper 3 is fixedly connected inside the tank cover 2. A motor 4 is fixedly installed in the middle of the upper end of the tank cover 2. The rotating shaft of the motor 4 passes through the tank cover 2 and is rotatably connected to the tank cover 2. A support pipe 5 is fixedly connected to the lower end of the rotating shaft of the motor 4. An adjustment mechanism 6 is provided on the support pipe 5. An end cap 7 is threadedly connected to the lower end of the carbonation tank 1.

[0022] like Figure 2 , Figure 3 , Figure 4As shown, the adjusting mechanism 6 includes an air pump 61. The air inlet pipe of the air pump 61 passes through the can lid 2 and is fixedly connected to the can lid 2. An annular groove 62 is provided on the outer side of the support pipe 5. The annular groove 62 and the air inlet pipe of the air pump 61 are slidably connected. By providing the annular groove 62, the air inlet pipe of the air pump 61 can slide inside the support pipe 5. A retaining sleeve 63 is fixedly connected to the outer side of the air inlet pipe of the air pump 61. The retaining sleeve 63 and the support pipe 5 are rotatably connected. By providing the retaining sleeve 63, the annular groove 62 is closed. A sliding tube 64 is slidably connected to the outer side of the support pipe 5. A guide block 65 is fixedly connected inside the sliding tube 64. The slide tube 64 is slidably connected to the support tube 5. The guide block 65 guides the movement of the slide tube 64. A turntable 66 is fixedly connected to the outside of the slide tube 64. A cylinder 67 is fixedly installed at the upper end of the can lid 2. The cylinder rod of the cylinder 67 passes through the can lid 2 and is slidably connected to it. A limit pin 68 is fixedly connected to the surface of the cylinder rod of the cylinder 67. The limit pin 68 is slidably connected to the turntable 66. The limit pin 68 guides the movement of the turntable 66. A hollow tube 69 is fixedly connected inside the slide tube 64. A support shaft 610 is fixedly connected to the lower end of the slide tube 64. A conveying knife 611 is fixedly connected to the outside of the slide tube 64. A support ring 612 is fixedly connected to the outside of the slide tube 64. A slip ring 613 is slidably connected to the outside of the slide tube 64. A spring 614 is provided on the outside of the slide tube 64. One end of the spring 614 is fixedly connected to the slip ring 613, and the other end of the spring 614 is fixedly connected to the support ring 612. By setting the spring 614, the slip ring 613 is elastically pressed down. A sealing plate 615 is fixedly connected to the outside of the slip ring 613. The sealing plate 615 is movably connected to the carbonization tank 1. Carbon dioxide is introduced into the support tube 5 through the air pump 61, and... The motor 4 drives the support tube 5 to rotate, which in turn causes the slide tube 64 to drive the hollow tube 69 to rotate, stirring the aggregate. This allows the carbon dioxide to be distributed more evenly in the aggregate, making the aggregate carbonization more uniform and efficient. The cylinder 67 drives the slide tube 64 to slide outside the support tube 5, which in turn causes the support ring 612 to elastically press down on the slide ring 613. This causes the slide ring 613 to drive the sealing plate 615 to move down and contact the inner wall of the carbonization tank 1. This allows the sealing plate 615 to seal the aggregate that has settled at the bottom of the carbonization tank 1. The rotating conveyor blade 611 facilitates the discharge of the aggregate.

[0023] The specific implementation process of this utility model is as follows: In use, aggregate is poured into carbonization tank 1 through feed hopper 3, then water is added, and feed hopper 3 is sealed. Carbon dioxide is introduced into support pipe 5 through air pump 61. The carbon dioxide in support pipe 5 can enter slide pipe 64 and then be discharged from perforated pipe 69. Motor 4 is started, driving support pipe 5 to rotate. Support pipe 5 drives slide pipe 64 to rotate. Carbon dioxide is introduced into support pipe 5 through air pump 61, and the rotation of support pipe 5 by motor 4 causes slide pipe 64 to drive perforated pipe 69 to rotate, thus stirring the aggregate. This allows the carbon dioxide to be more evenly distributed within the aggregate, resulting in more thorough carbonization. After the aggregate is carbonized in the carbonization tank 1, the motor 4 and air pump 61 stop working, causing the aggregate to settle. Then, the cylinder 67 is started, which drives the slide tube 64 to slide outside the support tube 5. This causes the support ring 612 to elastically press down on the slide ring 613, causing the slide ring 613 to move the sealing plate 615 down to contact the inner wall of the carbonization tank 1. This allows the sealing plate 615 to seal the aggregate that has settled at the bottom of the carbonization tank 1. Then, the motor 4 is started to continuously drive the slide tube 64 to rotate, which in turn causes the support shaft 610 to rotate. The support shaft 610 drives the conveying knife 611 to rotate, making it easier for the aggregate to be discharged.

[0024] Carbon dioxide is introduced into the support pipe 5 by the air pump 61, and the support pipe 5 is driven to rotate by the motor 4, which in turn causes the slide pipe 64 to drive the hollow pipe 69 to rotate, thus stirring the aggregate. This allows the carbon dioxide to be distributed more evenly in the aggregate, making the aggregate carbonization more uniform and efficient.

[0025] The cylinder 67 drives the slide tube 64 to slide outside the support tube 5, which in turn causes the support ring 612 to elastically press down the slide ring 613, causing the slide ring 613 to drive the sealing plate 615 to move down and contact the inner wall of the carbonization tank 1. This allows the sealing plate 615 to seal the aggregate that has settled in the lower part of the carbonization tank 1, and the rotating conveyor knife 611 makes it easier for the aggregate to be discharged.
