Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry-mixed mortar storage equipment, and more specifically to a dry-mixed mortar storage device. Background Technology
[0002] With social development and increased market demand, production capacity in various industries has risen accordingly. To meet this increased production capacity, dry-mixed mortar manufacturers must stockpile as much raw material as possible to ensure large-volume, continuous production. Furthermore, with the development of urbanization and the protection of agricultural land, the approval process for construction land use is becoming increasingly stringent. This has forced manufacturers to enlarge and heighten their silos to achieve greater storage capacity. However, as dry-mixed mortar silos become larger and taller, the negative impact of material segregation has become increasingly apparent. This segregation severely affects product quality and, consequently, its performance. Therefore, addressing this critical issue is essential before attempting to increase the size and height of silos.
[0003] There are two main causes of segregation in dry-mixed mortar: first, segregation caused by the drop height during transport; and second, segregation caused by accumulation-type drop height. Specifically, segregation caused by the drop height during transport occurs because the various raw materials mixed during the silo separation process, due to differences in particle size and density, cause the raw materials to separate as they fall into the silo. This phenomenon becomes more severe with increasing drop height. Segregation caused by accumulation-type drop height occurs because the various raw materials composing the mixture have different densities and particle sizes during storage in the silo. During the accumulation process, smaller, denser materials gradually sink over time until the bottom of the silo reaches equilibrium. This results in stratification of coarse and fine particles in the mixed material during storage. This phenomenon becomes more severe as the diameter of the silo increases. This phenomenon occurs to varying degrees in both mixed materials and single-material storage.
[0004] To ensure the needs of a specific construction cycle, storage tanks are set up on-site to temporarily store a predetermined weight of dry-mixed mortar. Besides the two main causes of segregation mentioned above, a third segregation phenomenon exists: after one batch of dry-mixed mortar is used up, a new batch is transported back to the storage tank. The previously stored mortar experiences segregation due to the accumulation and drop during transport, while the newly transported batch experiences segregation due to the material drop during transport. This phenomenon causes significant difficulties for users because the quality of the mortar at the interface between the two batches is unpredictable. Therefore, there is room for improvement in the existing technology to enhance the uniformity of the dry-mixed mortar and reduce segregation caused by drop during transport and accumulation. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a dry-mixed mortar storage device that can improve the uniformity of dry-mixed mortar temporarily stored in a dry-mixed mortar storage tank, thereby overcoming the defects in existing technologies.

[0018] Figure 2 for Figure 1 A magnified view of detail A. Detailed Implementation
[0019] like Figure 1 and Figure 2As shown, a dry-mixed mortar storage device includes a storage tank 1, a uniform distribution tank 2 above the storage tank 1, a first conveying pipe 3 connected to the top of the uniform distribution tank 2, a uniform distribution ring 4 inside the uniform distribution tank 2, a first guide cone 5 below the inner cavity of the uniform distribution ring 4, and partitions 6 below the first guide cone 5 in the uniform distribution tank 2. Several partitions 6 are arranged in a star shape and evenly distributed outside the central axis of the first guide cone 5. The inner cavity of the uniform distribution tank 2 below the first guide cone 5 is divided by the partitions 6. The storage tank 1 has several guide cavities, each with a discharge port 7. Each discharge port 7 and storage tank 1 are equipped with a second conveying pipe 8. Each second conveying pipe 8 has an anti-segregation pipe 9 at one end located inside the storage tank 1. These anti-segregation pipes 9 are evenly distributed in a star shape on the outer side of the central axis of the storage tank 1. A drive shaft 10 is located on the central axis of the storage tank 1, and stirring blades 11 are mounted on the drive shaft 10 located inside the storage tank 1. A star-shaped unloader 12 is located at the bottom of the storage tank 1. Both the storage tank 1 and the equalization tank 2 include a tank body, a cap on the top of the tank body, a sealing ring gasket between the cap and the tank body, and a first fixing bolt between the cap and the tank body.
[0020] Several first conveying pipes 3 are arranged in a star shape and evenly distributed outside the central axis of the equalization tank 2. The diameter of the inner cavity of the equalization ring 4 gradually decreases as the height of the equalization ring 4 decreases. The central axis of the equalization ring 4, the central axis of the first guide cone 5, and the central axis of the equalization tank 2 are located on the same axis. Several first conveying pipes 3 are arranged in a star shape and evenly distributed outside the central axis of the first guide cone 5. This facilitates the equalization ring 4 and the first guide cone 5 to guide the dry-mixed mortar conveyed by the first conveying pipes 3 and to convey it relatively evenly into several guide cavities. Then, the first conveying pipes 3 and the anti-segregation pipes 9 are used to guide the dry-mixed mortar in the corresponding guide cavities again, prompting the dry-mixed mortar to be conveyed into the storage tank 1 simultaneously by several anti-segregation pipes 9. The dry-mixed mortar entering the storage tank 1 is mixed again, reducing the segregation phenomenon caused by the height difference of materials during the conveying process of the dry-mixed mortar.
[0021] The bottoms of both the storage tank 1 and the equalization tank 2 are bucket-shaped, facilitating the guidance of the dry-mixed mortar at the bottom of either tank. Several baffles 6 are located at the bottom of the inner cavity of the equalization tank 2, with first connecting sleeves 13 mounted on each baffle 6. Second guide cones 14 are mounted on several baffles 6 below the first connecting sleeves 13. A drive shaft 10 is installed through both the storage tank 1 and the equalization tank 2, with its bottom located within the inner cavity of the storage tank 1. The first guide cone 5, the first connecting sleeve 13, and the second guide cone 14 are all fitted onto the drive shaft 10. The diameters of the circumscribed circles of both the first and second guide cones 14 gradually decrease from near to far from the storage tank 1. This design facilitates the guidance of the passing dry-mixed mortar using the shape of the bottom of the equalization tank 2 and the shape of the second guide cone 14, reducing the residue of dry-mixed mortar in the equalization tank 2.
[0022] A second connecting sleeve 15 is provided on the drive shaft 10 above the first guide cone 5, and a third guide cone 16 is provided on the drive shaft 10 above the second connecting sleeve 15. A limiting groove 17 is formed on the bottom of the third guide cone 16, and the top of the second connecting sleeve 15 is movably fitted into the inner cavity of the limiting groove 17. The cross-section of the gap between the third guide cone 16 and the second connecting sleeve 15 is an inverted L-shape. This gap between the third guide cone 16 and the second connecting sleeve 15 makes it difficult for dry-mixed mortar particles to be embedded in the gap between the drive shaft 10 and the first guide cone 5, causing wear to the drive shaft 10.
[0023] Furthermore, a third connecting sleeve 18 is provided on the drive shaft 10 above the third guide cone 16. The bottom of the third connecting sleeve 18 is connected to the top of the third guide cone 16. A second fixing bolt 19 is provided on the third connecting sleeve 18 and the drive shaft 10. The second fixing bolt 19 is used to fix the relative position of the third connecting sleeve 18 on the drive shaft 10, thereby adjusting the installation position of the third guide cone 16.
[0024] A top level gauge 20 is installed on the inner wall of the equalization tank 2 outside the several anti-segregation tubes 9. The top level gauge 20 facilitates feedback on the maximum material level height of the storage tank 1. A bottom level gauge 25 is installed on the inner wall of the equalization tank 2 below the top level gauge 20. The bottom level gauge 25 facilitates feedback on the minimum material level height of the storage tank 1. A connecting ring 21 is provided on the storage tank 1, and several support legs 22 are provided on the connecting ring 21. Each support leg 22 has a support foot pad 23 hinged to its end away from the connecting ring 21. The support foot pad 23 has through holes. When fixing the storage tank 1, the position of the support foot pad 23 needs to be fixed using foot nails. A drive motor 24 is provided above the equalization tank 2, and the output end of the drive motor 24 is connected to the top end of the drive shaft 10.
[0025] The instructions for using this product are as follows: Figure 1 and Figure 2 As shown, the dry-mixed mortar stored on the vehicle is transported to the inner cavity of the equalization tank 2 through several first conveying pipes 3; then, it is guided by the third guide cone 16 and the first guide cone 5 in sequence and enters several guide cavities; then, it is guided by the bottom of the equalization tank 2 and the second guide cone 14, and enters the inner cavity of the storage tank 1 through several second conveying pipes 8 and corresponding anti-segregation pipes 9. The dry-mixed mortar entering the inner cavity of the storage tank 1 through different anti-segregation pipes 9 is mixed again until the material level reaches the range fed back by the upper material level gauge 20.
[0026] After a dry-mixed mortar is delivered, or before it is put into use, the drive motor 24 needs to be started. The drive motor 24 drives the drive shaft 10 to move, which in turn drives the mixing blades 11 to move accordingly, so that the dry-mixed mortar temporarily stored in the storage tank 1 is mixed again.
[0027] In this embodiment, the material equalization tank 2, along with the equalization ring 4 and the first guide cone 5 installed inside the equalization tank 2, guides the dry-mixed mortar transported to the equalization tank 2 through several first conveying pipes 3. This ensures that the dry-mixed mortar, after being guided by the equalization ring 4 and the first guide cone 5, is evenly transported into several guide cavities. Then, the corresponding second conveying pipe 8 and anti-segregation pipe 9 are used to transport the dry-mixed mortar, thereby re-mixing the dry-mixed mortar that has entered the inner cavity of the storage tank 1 through different anti-segregation pipes 9, reducing segregation caused by material height differences. After the transport is completed or before use, the drive shaft 10 is used to drive the dry-mixed mortar originally stored in the inner cavity of the storage tank 1 and the dry-mixed mortar that has been transported to the inner cavity of the storage tank 1 again to mix, thereby reducing segregation caused by material level differences when the dry-mixed mortar is piled up.
