Description

Technical Field

[0001] The utility model relates to the technical field of bricks, in particular to a lightweight carbon-fixing hollow brick. Background Art

[0002] In order to promote the development of China's CCUS technology and better support the realization of carbon peak and carbon neutrality goals, carbon dioxide is used to strengthen recycled aggregates to make them have better physical and mechanical properties and durability; it also reduces carbon dioxide emissions. The carbon fixation process of existing carbon fixation bricks is generally to put the pressed bricks into a carbonization furnace, and then inject a certain pressure of carbon dioxide into the carbonization furnace. The carbon dioxide reacts with the corresponding substances in the bricks to form calcium carbonate. However, existing bricks are generally rectangular in shape, with limited wall thickness and contact area with carbon dioxide, resulting in low carbon fixation efficiency and carbon fixation amount. Utility Model Content

[0003] The purpose of the utility model is to provide a lightweight carbon-fixing hollow brick. By arranging the first type groove and the second type groove on the surface of the brick, the absorption contact area of ​​carbon dioxide during carbon fixation can be increased. At the same time, the wall thickness is reduced to allow the brick to fully react with carbon dioxide, which can effectively improve the carbon fixation efficiency and carbon fixation amount.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A lightweight carbon-fixing hollow brick comprises a rectangular brick body, the brick body comprises a top surface and a bottom surface which are arranged back to back; the top surface and the bottom surface are respectively provided with two first-shaped grooves which are arranged symmetrically in front and back and two second-shaped grooves which are arranged symmetrically in left and right; the two first-shaped grooves on the top surface are arranged symmetrically with the two first-shaped grooves on the bottom surface, and the two second-shaped grooves on the top surface are arranged symmetrically with the two second-shaped grooves on the bottom surface. The first-shaped groove and the second-shaped groove have similar structures, but are not of the same size.

[0006] By arranging the first type groove and the second type groove on the top surface and the bottom surface, the ratio of the surface area to the volume of the hollow brick can be increased, and the contact area between the carbon dioxide and the brick body can be greatly increased during carbon fixation, thereby accelerating the absorption efficiency of carbon dioxide and improving the carbon fixation efficiency of the brick; at the same time, the existence of the first type groove and the second type groove can reduce the local wall thickness of the brick body, allowing more carbon dioxide to enter the interior of the brick, and the interior of the brick can fully absorb and react to the carbon dioxide, thereby increasing the carbon fixation amount.

[0007] The utility model is further configured as follows: the first type of groove comprises an open triangular groove, a triangular groove is formed on the bottom surface of the open triangular groove, and a round hole is formed on the bottom surface of the triangular groove.

[0008] The hollow bricks can be used for paving sidewalks in a rectangular array. The first-shaped grooves and the second-shaped grooves on the top surface can become regular patterns after being laid in a rectangular array of multiple hollow bricks, which has a certain aesthetic appeal. The first-shaped grooves and the second-shaped grooves on the bottom surface can increase the bonding ability with the foundation below.

[0009] The utility model is further configured such that: the corner of the open triangular sink and the three corners of the triangular sink are each formed with a rounded corner;

[0010] The side wall of the open triangular sink is provided with a taper;

[0011] The triangular groove and the circular hole are both arranged in a conical shape with a larger outer side and a smaller inner side.

[0012] The taper and cone shape settings can facilitate the forming and demoulding of hollow bricks.

[0013] The utility model is further configured that: a separation portion is provided between the circular hole of the first groove on the top surface and the corresponding circular hole of the first groove on the bottom surface. The separation portion can reduce the mutual influence between the two symmetrically arranged grooves, improve the overall stability of the entire brick body, and further increase the contact reaction area with carbon dioxide.

[0014] The utility model is further configured that the depth of the open triangular sink groove does not exceed 4 mm. This depth may look like a pattern, but has little effect on pedestrians walking.

[0015] The utility model is further configured such that: four blind grooves with lower side openings are formed on the bottom surface (102), and each blind groove is arranged between a corresponding first groove and a second groove that are adjacently arranged.

[0016] By providing blind grooves, the contact reaction area with carbon dioxide can be further increased, and the local wall thickness of the brick can be further reduced.

[0017] The utility model is further configured as follows: the brick body is pressed from lightweight concrete; the lightweight concrete includes recycled lightweight aggregate, building stone powder and cement. The materials of concrete bricks in the prior art generally include gravel, sand, cement, etc., which are relatively expensive, and the quality of the cement bricks after molding is also relatively large; while the solid brick is made by mixing recycled lightweight aggregates such as slag and coal slag, stone powder and cement, which not only improves the utilization rate of coal slag, etc., but also reduces the cost of raw materials for bricks, and the quality of bricks of equal volume can also be reduced, reducing transportation costs.

[0018] The outstanding effects of the utility model are:

[0019] Compared with the prior art, the first type groove and the second type groove are arranged on the surface of the brick to increase the absorption contact area of ​​carbon dioxide during carbon fixation. At the same time, the wall thickness is reduced to allow the brick to fully react with carbon dioxide, which can effectively improve the carbon fixation efficiency and carbon fixation amount.

[0020] When the bricks are laid in array, the first-shaped grooves and the second-shaped grooves can form a regular pattern, which can increase the overall aesthetics of the laid bricks. BRIEF DESCRIPTION OF THE DRAWINGS
