Description

Technical Field

[0001] This application relates to the field of fly ash mineralization technology, and in particular to a fly ash mineralization vibratory mixing device. Background Technology

[0002] With the acceleration of modern urbanization, the amount of solid waste generated is also gradually increasing. Waste incineration, as an important means of solid waste treatment, is widely used in areas such as municipal solid waste and industrial waste treatment. After detoxification treatment, the fly ash from incineration can be used as a concrete material. Typically, fly ash is mixed with cement and mineralizers, and an appropriate amount of water is added for stirring to form the concrete material needed in building construction.

[0003] Existing concrete mixers include a frame housing, a mixing mechanism fixed within the frame housing, and a drive mechanism that rotates the mixing mechanism. Cement powder, fly ash, and mineralizer are added into the frame housing, and the drive mechanism is activated to rotate the mixing mechanism. After all materials are mixed evenly, they are discharged from the frame housing to produce the desired concrete components.

[0004] Regarding the aforementioned technologies, the inventors believe that the low dispersion and insufficient bonding of mineralizers and fly ash during concrete mixing can affect the construction of concrete components. Therefore, it is necessary to provide a device that can improve the bonding between mineralizers and fly ash. Utility Model Content

[0019] By adopting the above technical solution, the vibration mechanism is equipped with a vibrator and a vibration head. The vibration head includes a vibration seat and multiple vibration rods, which can extend into the concrete to vibrate the material, making the concrete more fully and uniform, and improving the mixing quality of various materials in the concrete.

[0020] Optionally, the top of the exciter base has a mounting ring that surrounds the output end of the exciter; the mounting ring includes two mounting half-rings and bolts and nuts connecting the two mounting half-rings.

[0022] In summary, this application includes at least one of the following beneficial technical effects: A fly ash mineralization vibration mixing device divides the inner cavity of the frame shell into a mixing chamber and a vibration chamber by setting a partition plate, thereby reducing the mutual interference between mixing and vibration. The mixing mechanism in the mixing chamber and the vibration mechanism in the vibration chamber can fully mix the concrete, which facilitates the full combination of mineralizer and fly ash and improves the uniformity of material mixing in the concrete. By setting up a conveying screw and a connecting sleeve that connects the mixing chamber and the vibration chamber, the concrete in the mixing chamber is transported to the vibration chamber, making the connection between the concrete mixing operation and the vibration operation smoother and further improving the construction efficiency. The screw frame is slidably connected to the frame housing.
