Description

Technical Field

[0001] The present application relates to the technical field of concrete carbonization, and in particular to a waste concrete carbonization device. Background Art

[0002] Industrial waste slag generated in the industrial production process has increased rapidly with the rapid development of industry. The waste generated by domestic enterprises cannot be handled in time, resulting in a large amount of waste slag occupying land and polluting the environment. The application of industrial waste slag in building materials has become the main way for its resource application. At present, in the field of civil engineering materials, wastes such as steel slag and waste concrete can be directly crushed and used as concrete aggregates, which has a good economic effect. These solid waste slags are generally highly alkaline and have a strong ability to absorb carbon dioxide. Current research shows that not only a large amount of carbonate minerals are generated in the carbonized solid waste recycled aggregates, but also the mechanical strength of the solid waste recycled aggregates is greatly improved. The carbonation of solid waste recycled aggregates has not only become a more economical and efficient way to utilize industrial waste slag, but also is expected to become an important technical means for the storage and solidification of carbon dioxide.

[0003] The invention patent with announcement number CN113943120B proposes a carbonization device for regenerating concrete aggregate from solid waste for concrete, including a carbonization box with a waste delivery port at the upper end, a carbon dioxide introduction pipe fixedly connected to the upper end of the carbonization box, a sealing assembly is provided at the waste delivery port, the sealing assembly includes a first sealing member and a second sealing member, and the first sealing member and the second sealing member are respectively located on the upper and lower sides of the waste delivery port and are fixedly connected to the carbonization box, a transmission mechanism is provided on the inner side of the carbonization box, the transmission mechanism includes a first transmission mechanism and a second transmission mechanism arranged upper and lower, and a discharge port is provided at the lower end of the carbonization box.

[0004] The above-mentioned device cooperates with the first seal and the second seal to prevent carbon dioxide from leaking out through the discharge port when filling aggregate into the carbonization device, so as to solve the problem that the existing device is generally an open structure. During the process of putting in aggregate, the carbon dioxide in the carbonization bin is easy to overflow through the discharge port, causing harm to the health of the workers. The present application adopts another technical solution to solve the above-mentioned technical problem. Utility Model Content

[0005] The utility model aims to solve or at least alleviate the problem that in the prior art device, during the process of placing aggregates, carbon dioxide in the carbonization bin easily overflows through the discharge port, causing damage to the health of the workers.

[0008] By adopting the above technical solutions, during use, the user first starts the first motor to drive the storage bucket to rotate, rotates the communication holes provided on the side wall of the storage bucket to the top of the storage bucket, so that the bottom end of the feed hopper can be connected to the inner cavity of the storage bucket through the communication holes, and then imports the waste concrete into the inner cavity of the storage bucket through the feed hopper and the communication holes. After the import is completed, the user starts the first motor again, drives the storage bucket to rotate 180 degrees through the first motor, rotates the communication holes to the bottom of the storage bucket, so that the waste concrete stored in the storage bucket can fall into the carbonization box below the feeding structure under its own gravity for crushing and carbonization. Since the periphery of the storage bucket is always in contact with the elastic sealing plates installed on the inner wall of the carbonization box, the elastic sealing plates and the side wall of the storage bucket are used to cooperate to seal the bottom end of the feed hopper, so that the carbon dioxide below cannot leak through the feed hopper whether the storage bucket feeds or discharges through the communication holes, and it is possible to avoid as much as possible the problem that the carbon dioxide in the carbonization chamber is likely to overflow through the discharge port during the process of putting in the aggregate in the existing device, which causes damage to the physical health of the staff.

A auger is rotatably connected in the inner cavity of the transmission pipe, and a third motor for driving the auger to rotate is installed on the bottom side wall of the carbonization tank.

[0016] By adopting the above technical solution, after the waste concrete cured with carbon dioxide falls into the transmission pipe, the third motor can be started, and the auger is driven by the third motor to rotate. Cooperating with the transmission pipe, the waste concrete falling into the inner part of the transmission pipe is exported from the end of the transmission pipe far from the third motor for secondary utilization.

[0017] Optionally, the peripheral side of the top end of the aggregate hopper is fixedly connected to the inner walls of the four sides of the carbonization tank, and the bottom end of the aggregate hopper penetrates through the transmission pipe and is communicated with the inner cavity of the transmission pipe.

[0019] Optionally, bearings are installed at the connections between the output ends of the first motor, the second motor and the third motor and the carbonization tank.

[0020] By adopting the above technical solution, the bearings are provided to reduce the frictional resistance when the output ends of the first motor, the second motor and the third motor rotate, and reduce the energy consumption.

[0021] Optionally, mounting seats are fixedly connected to the outer walls of the first motor, the second motor and the third motor, and through holes penetrating the mounting seats are opened at both ends of the mounting seats.

[0024] Through the cooperative setting among structures such as a storage bin, a communication hole, a first motor, and an elastic sealing plate, during use, waste concrete is first introduced into the storage bin through the communication hole, and then the storage bin is flipped for discharging. Since the periphery of the storage bin always fits with the elastic sealing plate installed on the inner wall of the carbonization tank, the elastic sealing plate and the side wall of the storage bin cooperate to seal the bottom end of the feed hopper, so that when the storage bin feeds or discharges through the communication hole, the carbon dioxide below cannot leak out through the feed hopper, thus avoiding as much as possible the problem that in the existing device, during the process of putting in aggregates, the carbon dioxide in the carbonization bin easily overflows through the discharge port, causing harm to the physical health of the staff.
