Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building block production, and particularly relates to a crack-resistant concrete building block and a processing method thereof. BACKGROUND

[0002] The concrete building block is a brick-shaped or block-shaped material made of cement as a binding material, fine aggregate (such as sand) and / or coarse aggregate as an aggregate, and configured with a water-cement ratio and porosity according to a design strength grade, and combined with an additive to optimize workability, strength and durability, to improve workability and strength development, and formed and cured.

[0003] In the preparation and molding process of the concrete building block, chemical additives (such as water-reducing agents, early strength agents, retarders, and high-efficiency additives of admixtures such as fly ash) play a key role in strength development. By reducing the water-cement ratio without sacrificing fluidity, reducing porosity and optimizing the distribution of cement hydration products, the early and late compressive strength growth curves can be significantly improved, the curing period can be shortened, and the stability and durability of the structure under the load can be improved. In addition, the additive can also control the shrinkage and crack risk to ensure the consistency of the strength of the building block during construction, transportation and use, thereby improving the overall building performance and economy.

[0004] However, in the existing process, the chemical additive is usually directly fed into the main material for mixing, which can easily limit the mixing efficiency of the mixing process, and can also cause uneven dispersion of the additive in the matrix and local aggregation, thereby causing inconsistent strength development and pore structure, leading to cracks in the building block, and affecting the quality stability and long-term performance of the building block.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Reference Figure 1 - Figure 6 This invention provides three technical solutions: Example 1:

[0025] A crack-resistant concrete building block and its processing method are disclosed, comprising a first mixing cylinder 1, a first mixing assembly fixedly installed in the middle of the upper surface of the first mixing cylinder 1, a connecting pipe 2 fixedly connected to one side of the upper surface of the first mixing cylinder 1, a second mixing assembly fixedly connected to the upper surface of the connecting pipe 2, a first mounting frame 3 fixedly connected to the outer surface of the first mixing cylinder 1, a second mounting frame 4 fixedly connected inside the first mounting frame 3, a receiving assembly fixedly installed on the lower surface of the second mounting frame 4, a base plate 36 fixedly connected to the bottom end of the inner side of the second mounting frame 4, a third mounting frame 5 fixedly connected to one side of the upper surface of the base plate 36, and a pressing assembly fixedly installed on the upper surface of the third mounting frame 5. The first mixing assembly includes a first motor 6. The lower surface of the first motor 6 is fixedly installed in the middle of the upper surface of the first mixing cylinder 1. The output end of the first motor 6 is fixedly connected to a first rotating rod 7. The outer surface of the first rotating rod 7 is fixedly connected to a stirring blade 8. When the first motor 6 is started, the stirring blade 8 is driven to rotate via the first rotating rod 7, which can mix and stir the material as a whole. The stirring blade 8 is spiral-shaped, which can transport the material at the bottom to the top for continuous mixing, further improving the uniformity of mixing. This makes the internal stress distribution of the material more uniform, reduces the risk of local defects and stress concentration, and thus reduces the generation and propagation of cracks, effectively preventing brick cracking and ensuring the quality stability and long-term performance of the brickwork.

[0026] The second mixing assembly includes a second mixing cylinder 9. The lower surface of the second mixing cylinder 9 is fixedly connected to the upper surface of the connecting pipe 2. A second motor 10 is fixedly installed in the middle of the upper surface of the second mixing cylinder 9. A second rotating rod 11 is fixedly connected to the output end of the second motor 10. A mixing blade 12 is fixedly connected to the outer surface of the second rotating rod 11. An auxiliary material feed pipe 13 is fixedly connected to one side of the upper surface of the second mixing cylinder 9. Chemical additives are added into the interior of the second mixing cylinder 9 through the auxiliary material feed pipe 13. The second motor 10 is then started, which drives the mixing blade 12 to rotate via the second rotating rod 11. The mixing blade 12 can perform preliminary mixing and stirring of the chemical additives inside the second mixing cylinder 9. Subsequently, the chemical additives are allowed to enter the interior of the first mixing cylinder 1 and be mixed with the main material of the block, thereby improving the mixing efficiency and dispersion uniformity and reducing aggregation.

[0027] A main material feed pipe 14 is fixedly connected to the other side of the upper surface of the first mixing cylinder 1. A butterfly valve 15 is fixedly installed inside the connecting pipe 2. The main material feed pipe 14 can be used to add the main material for bricklaying into the first mixing cylinder 1. Opening the butterfly valve 15 can allow the mixed chemical additives to be added into the main material of the first mixing cylinder 1 to achieve overall mixing. Example 2:

[0028] Based on Embodiment 1: The receiving component includes a third motor 16, the upper surface of which is fixedly mounted on the lower surface of the second mounting bracket 4. A belt drive component 17 is fixedly connected to the output end of the third motor 16. A third rotating rod 18 is fixedly connected to the upper surface of the belt drive component 17. A gear 19 is fixedly connected to the top of the outer surface of the third rotating rod 18. A rack 20 meshes with the outer surface of the gear 19. A sealing plate 21 is fixedly connected to one side of the rack 20. A receiving box 22 is fixedly connected to one side of the sealing plate 21. The sealing plate 21 can be used to control the first mixing cylinder. The discharge port at the bottom is sealed to ensure that the material is mixed inside the first mixing cylinder 1. After the material is mixed, the third motor 16 is started and drives the third rotating rod 18 to rotate via the belt drive component 17. The gear 19 rotates accordingly and drives the sealing plate 21 to move left and right via the rack 20, so that the receiving box 22 moves to the bottom of the first mixing cylinder 1. The material can be received in equal amounts. Then, the material enters the forming box 35, which can ensure that the amount of block forming material is consistent, thereby achieving consistency in the strength, density and appearance of the blocks and ensuring the quality of bricklaying.

[0029] A circular groove matching the diameter of the receiving box 22 is provided on one side of the upper surface of the second mounting frame 4. A discharge hopper 23 is fixedly connected to the lower surface of the second mounting frame 4 at the periphery of the circular groove. After the receiving box 22 receives the material in equal quantities, the receiving box 22 can be driven to the circular groove by the rack 20. Under the action of gravity, the material falls into the forming box 35 through the discharge hopper 23, so as to achieve smooth material feeding and ensure stable material level, thereby ensuring the continuity of the material feeding process. Example 3:

[0030] Based on Embodiments 1 and 2: The pressing assembly includes a first cylinder 24, the lower surface of which is fixedly mounted on the upper surface of the third mounting bracket 5. A top plate 25 is fixedly connected to the output end of the first cylinder 24. Extension rods 26 are fixedly connected to the four corners of the lower surface of the top plate 25. A cover plate 27 is fixedly connected to the bottom end of the extension rods 26. A second cylinder 28 is fixedly mounted in the middle of the upper surface of the cover plate 27. A pressure plate 29 is fixedly connected to the output end of the second cylinder 28. Springs 30 are fixedly connected to the four corners of the upper surface of the pressure plate 29. The top ends of the springs 30 are fixedly connected to the four corners of the lower surface of the cover plate 27. When the connection is established, the first cylinder 24 is activated to push the top plate 25 down, so that the cover plate 27 covers the receiving box 22. At this time, the pressure plate 29 enters the receiving box 22 and performs initial compression molding. Subsequently, the second cylinder 28 is activated to push the pressure plate 29 down continuously to perform strong compression. Through this staged pressure application, the voids inside the material can be gradually squeezed out and rearranged, thereby reducing the eccentric density difference and internal voids, obtaining a more uniform pore structure, thereby increasing the bulk density, reducing permeability and capillary conduction, enhancing impermeability and durability, and further reducing the risk of crack formation.

[0031] Both ends of the upper surface of the base plate 36 are fixedly connected to the uprights 31. A conveying assembly is fixedly installed on one side of the uprights 31. The uprights 31 facilitate the installation and support of the rollers 33, so that the conveyor belt 34 is at the required height.

[0032] The conveying assembly includes a fourth motor 32, one side of which is fixedly mounted on one side of the upright frame 31. A roller 33 is fixedly connected to the output end of the fourth motor 32, and a conveyor belt 34 is fixedly connected to the outer surface of the roller 33. When the fourth motor 32 is started, it drives the conveyor belt 34 via the roller 33 to convey the forming box 35, so that the forming box 35 moves to the bottom of the discharge hopper 23 to receive the material. Then, the forming box 35 is conveyed to the bottom of the third mounting frame 5, realizing the continuous and automated production process, reducing downtime and manual intervention, and improving production efficiency.

[0033] A forming box 35 overlaps on the upper surface of the conveyor belt 34. The size of the forming box 35 is adapted to the pressure plate 29. The forming box 35 facilitates the overall forming of bricks, ensures the consistency of each brick, and improves the appearance quality and assembly consistency.

[0034] Working principle: First, the required chemical additives are added into the second mixing cylinder 9 through the auxiliary material feed pipe 13. Then, the second motor 10 is started, driving the mixing blade 12 to rotate via the second rotating rod 11 for mixing. Subsequently, the butterfly valve 15 is opened, allowing it to enter the first mixing cylinder 1 through the connecting pipe 2. After the main material is added through the main material feed pipe 14, the first motor 6 is started, driving the stirring blade 8 to rotate counterclockwise via the first rotating rod 7, mixing the bottom material by conveying it upwards. Next, the third motor 16 is started, driving the third rotating rod 18 to rotate via the belt drive component 17. The gear 19 rotates accordingly, driving the sealing plate 21 to move left and right via the rack 20, so that the receiving box 22 moves to below the first mixing cylinder 1. At the same time, the first Motor 6 drives the stirring blade 8 to reverse and transport the material into the receiving box 22. Then, the receiving box 22 is moved to the circular groove so that the material is discharged through the discharge hopper 23. Next, the fourth motor 32 is started and the roller 33 drives the conveyor belt 34 to transport the forming box 35 so that the forming box 35 moves below the discharge hopper 23 to receive the material. Finally, when the forming box 35 moves to the bottom of the third mounting frame 5, the first cylinder 24 is started to push the top plate 25 down so that the cover plate 27 covers the receiving box 22. At this time, the pressure plate 29 enters the receiving box 22 to perform preliminary extrusion and molding. Then, the second cylinder 28 is started to push the pressure plate 29 down continuously to perform strong extrusion.
