[0030] See also Figure 1 The utility model provides an aggregate ball-forming device, including a ball-forming disk 1, an air intake assembly, a material distribution structure 3 and a driving member 4. The ball-forming disk 1 includes a bottom plate 11 and a cover plate 12, which together define a receiving chamber (not shown in the figure). The cover plate 12 is arranged on the bottom plate 11 and is used to seal the receiving chamber; the cover plate 12 is provided with an air inlet 121, an air outlet 122 and a feed port 123 which are connected to the receiving chamber, and the feed port 123 is used to put raw materials into the receiving chamber. The air outlet end of the air intake assembly extends into the air inlet 121 to transport carbon dioxide gas into the receiving chamber, and the air outlet 122 is used to discharge the carbon dioxide in the receiving chamber. The material distribution structure 3 is at least partially arranged in the receiving chamber. The driving member 4 is connected to the bottom plate 11, and is used to drive the bottom plate 11 to rotate relative to the cover plate 12 and the material distribution structure 3, so that the raw materials between the bottom plate 11 and the material distribution structure 3 are balled.

[0031] The utility model utilizes carbon dioxide mineralization technology to prepare aggregate pellets, which can achieve green environmental protection. The carbon dioxide mineralization technology is to react carbonation of carbon dioxide gas with solid waste calcium and magnesium components to generate calcium carbonate or magnesium carbonate, thereby permanently and stably solidifying carbon dioxide in building materials (concrete in the utility model).

[0032] It should be noted that, in the present invention, fly ash, carbide slag, bottom ash and carbon dioxide gas are used as raw materials to prepare aggregate balls, and the aggregate balls are used to replace the sintered expanded clay, lightweight aggregate sand and lightweight aggregate stone in the prior art. Moreover, the aggregate balls do not need to be sintered, thereby achieving the requirements of green environmental protection and meeting the use requirements of concrete.

[0033] In this way, by setting the material distribution structure 3 and the driving member 4, the driving member 4 drives the chassis 11 to rotate, so that the raw materials can be made into small balls; by setting the air intake component to introduce carbon dioxide gas into the accommodating chamber, the carbon dioxide gas and the raw materials in the accommodating chamber are mineralized to form aggregate small balls, thereby making full use of the carbon dioxide gas and achieving green environmental protection; by setting the cover plate 12 connected to the chassis 11 to form a sealed accommodating chamber, the carbon dioxide gas is fully in contact with the raw materials in the accommodating chamber, and the carbon dioxide gas is continuously introduced into the accommodating chamber, which can improve the mineralization efficiency inside the aggregate small balls and make the mineralization distribution more uniform.

[0034] See also Figure 1 In some embodiments, the ball forming disk 1 further includes a ball bearing (not shown in the figure), the bottom plate 11 is connected to the inner ring or the ball of the ball bearing, and the cover plate 12 is connected to the outer ring of the ball bearing. Specifically, the ball bearing includes an inner ring, an outer ring and a plurality of balls, all of which are sequentially arranged between the inner ring and the outer ring, and the inner ring and the balls can rotate synchronously, while the outer ring remains relatively stationary.

[0035] In some embodiments, a plurality of ball bearings are provided at intervals. It is understandable that the number of ball bearings can be set according to actual use needs, and no further limitation is made here.

[0036] See also Figure 1 In some embodiments, the air intake assembly includes an air source 21 and an air intake pipeline 22 , one end of the air intake pipeline 22 is connected to the air source 21 , and the other end extends into the air inlet 121 .

[0037] Furthermore, in some embodiments, the air intake component also includes a first gas concentration sensor (not shown in the figure), a gas pressure sensor (not shown in the figure) and a flow meter (not shown in the figure) arranged on the intake pipe 22, and the first gas concentration sensor, the gas pressure sensor and the flow meter are used to detect the concentration, pressure and flow of the carbon dioxide gas in the intake pipe 22, respectively.

[0038] Optionally, in some embodiments, the gas source 21 is a gas storage tank for storing carbon dioxide gas.

[0039] See also Figure 1In some embodiments, the aggregate pelletizing device further includes a gas outlet component 5, the gas outlet component 5 includes a gas outlet pipeline 51 and a second gas concentration sensor 52 arranged on the gas outlet pipeline 51, and the second gas concentration sensor 52 is used to detect the concentration of carbon dioxide gas in the gas outlet pipeline 51.

[0040] It should be noted that, in the present invention, a first gas concentration sensor is provided on the air inlet pipe 22 to detect the concentration of the carbon dioxide gas input into the air inlet 121, and a second gas concentration sensor 52 is provided on the air outlet pipe 51 to detect the concentration of the carbon dioxide gas discharged from the air outlet 122. The mineralization rate of the carbon dioxide gas with different input concentrations can be obtained by calculation.

[0041] See also Figure 1 In some embodiments, the cover plate 12 is further provided with a sealing plate 13, which is rotatably connected to the cover plate 12, and the sealing plate 13 is correspondingly arranged with the feed port 123 to seal the feed port 123. Optionally, the sealing plate 13 and the cover plate 12 are connected by a hinge. It can be understood that there are many ways of rotational connection, which can meet the actual use requirements, and will not be repeated here.

[0042] In some embodiments, the driving member 4 is a driving motor, and an output shaft of the driving motor is connected to the chassis 11 .

[0043] See also Figure 1 In some embodiments, the cover plate 12 is further provided with a through hole 124 communicating with the accommodating cavity. The material dividing structure 3 includes a support member 31 and a material dividing shovel 32. One end of the support member 31 extends into the through hole 124 and is connected to the material dividing shovel 32. A gap is provided between the material dividing shovel 32 and the inner bottom wall of the chassis 11. The gap between the material dividing shovel 32 and the inner bottom wall of the chassis 11 is used to accommodate raw materials.

[0044] It is understandable that the side of the dividing shovel 32 facing the raw material is flat so as to cooperate with the chassis 11. In addition, when the driving member 4 drives the chassis 11 to rotate, the dividing shovel 32 remains stationary, so that the raw materials in the gap between the dividing shovel 32 and the chassis 11 roll to form aggregate balls.

[0045] It should be noted that, in the present embodiment, when preparing aggregate balls, the ball forming disk 1 is tilted, and the larger aggregate balls will fall to the bottom of the accommodating cavity under the action of gravity, while the smaller aggregate balls are located above the accommodating cavity due to their smaller weight due to the centrifugal force generated by the rotation of the chassis 11 and the obstruction of the dividing shovel 32, thereby separating the large and small aggregate balls.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
