Description

Technical Field

[0001] The utility model relates to the technical field of premixed concrete, in particular to a premixed concrete production device. Background Art

[0002] Ready-mixed concrete, also known as commercial concrete, refers to a concrete mixture consisting of cement, aggregates (such as sand, stone, etc.), water, and admixtures and mineral admixtures as needed. After precise measurement and mixing at a mixing station, it is sold and transported to the place of use within a specified time by a transport vehicle.

[0003] Many premixed concrete production equipment on the market currently have the disadvantage of single mixing function. The mixing process is lengthy, which not only slows down the construction progress, but also increases energy consumption and production costs. At the same time, these equipment generally lack drying function during the mixing process. The moisture content in the concrete has a crucial impact on its final performance, and the lack of drying steps directly leads to the difficulty of accurately controlling the moisture content of the concrete, which in turn affects its strength, durability and working performance. Too high a moisture content may cause shrinkage cracks in the concrete during the hardening process, reducing the safety of the structure, while too low a moisture content may increase the difficulty of construction and affect the workability and pumpability of the concrete. Therefore, we propose a premixed concrete production equipment. Utility Model Content

[0016] A bearing is fixedly installed at the center of the other side of the left side plate 1. One end of the hollow tube 9 passes through the bearing, the left side plate 1 and the interior of the chassis 10 in sequence. The outer wall of the hollow tube 9 is fixedly connected to the inner ring of the bearing. One end of the transmission rod 14 is fixedly connected to the bearing fixedly installed at the center of the other side of the right side plate 2, thereby ensuring the stability of the mixing drum 3 during rotation.

[0017] The blower motor 11 is fixedly connected to a second drive shaft via an output end on one side thereof, and one end of the second drive shaft is fixedly connected to the center of one side of the fan blade 12 . The fan blade 12 is driven to rotate at high speed by starting the blower motor 11 .

[0018] The driving motor 15 is fixedly connected to the third driving shaft through the output end on one side thereof, and one side of the third driving shaft passes through the outside of the right side plate 2. A driving wheel 16 is fixedly installed on the center position of the surface of the transmission rod 14 and one end of the third driving shaft. The two driving wheels 16 are connected by a belt 17.

At the same time, the design of the cover plate and the lock ensures the sealing during the mixing process, prevents the leakage of concrete or impurities from entering the mixing drum 3, and ensures the mixing quality.

[0021] Working principle: First, the operator adds an appropriate amount of concrete raw materials into the mixing drum 3 through the inlet and outlet pipes, and closes and locks the cover to ensure the sealing during the mixing process. Subsequently, the mixing motor 6 is started. The mixing motor 6 drives the rotating rod 7 to rotate inside the mixing drum 3 through the first drive shaft at its output end, and the mixing blades 8 on the rotating rod 7 rotate accordingly, and the concrete raw materials in the mixing drum 3 are finely mixed to ensure that the raw materials are evenly mixed. At the same time, if it is necessary to further enhance the mixing effect, the drive motor 15 can be started. The drive motor 15 is connected to the transmission of the third drive shaft, the transmission wheel 16 and the belt 17 to drive the transmission rod 14 to rotate, and then the entire mixing drum 3 rotates around its axis. This dual mixing method, that is, the local mixing of the stirring blades 8 combined with the overall rotation of the mixing drum 3, realizes all-round and multi-level mixing of concrete in the mixing drum 3, improves the mixing efficiency and the quality stability of the concrete, and during the mixing process, if it is necessary to dry the concrete, the blowing motor 11 can be started. The blowing motor 11 The second drive shaft at its output end drives the fan blades 12 to rotate at high speed, generating a strong wind flow, which is guided into the interior of the chassis 10, and after being heated by the heating wire 13, it is converted into high-temperature hot air, which is then sent directly into the interior of the mixing drum 3 through the hollow tube 9, an efficient transmission channel, to evenly dry the concrete, remove excess moisture, and improve the quality of the concrete. During the entire mixing and drying process, the stable structure composed of the connecting plate 18, the bracket 19 and the stabilizing roller 20 between the left plate 1 and the right plate 2 ensures the stability of the mixing drum 3 during rotation, reduces the noise and wear that may be caused by vibration or imbalance, and ensures the smooth progress of the mixing and drying process. Finally, when the concrete reaches the predetermined mixing and drying effect, the mixing motor 6, the drive motor 15 and the blowing motor 11 are turned off, the cover of the inlet and outlet pipes is opened, the mixed concrete is taken out, and the next step of production or construction operation is carried out. The entire workflow is efficient and stable, and can meet the needs of modern buildings for high-quality concrete materials.

This innovative design realizes the double superposition of mixing methods. On the one hand, the rotation of the mixing blade 8 realizes the fine mixing inside the concrete. On the other hand, the rotation of the mixing drum 3 promotes the overall flow and mixing of the concrete in the drum, further enhancing the mixing effect, which can not only greatly shorten the mixing time, but also improve the production efficiency. Efficiency can also significantly improve the quality stability of concrete. The design of the hollow tube 9, the chassis 10, the blower motor 11, the fan blades 12 and the heating wire 13, during the pre-mixing process, the blower motor 11 is started to drive the fan blades 12 to rotate at a high speed, thereby generating a strong wind flow, which is guided through the heating wire 13 in the chassis 10. After the heating wire 13 is energized, it heats up rapidly and converts the wind flow into high-temperature hot air. The high-temperature hot air is then directly sent into the mixing drum 3 through the efficient transmission channel of the hollow tube 9 to dry the concrete, thereby avoiding the influence of moisture on the pre-mixed concrete, improving the quality and production efficiency of the concrete, and meeting the demand of modern buildings for high-quality concrete materials.
