Abstract
The utility model discloses a degassing chamber of online refining device of aluminium liquid, including the degassing chamber main part, its characterized in that: the degassing chamber main body is formed by building a plurality of module bricks made of non-stick aluminum hard materials, a degassing chamber water inlet is formed in the upper portion, a deslagging port is formed in the bottom portion, a turbulence brick is arranged in the degassing chamber, a diving brick is arranged at the degassing chamber water inlet, and a nano bubble refining brick and an air supply pipe are arranged at the bottom portion of the degassing chamber. The utility model discloses when using, high-purity hydrogen or argon gas are in getting into the degasification room by the air supply pipe, refine the brick dispersion through the nanometer bubble, and bump with the vortex brick under mechanical agitator stirs, and dispersive bubble is broken once more, carries out complete abundant combination with aluminium water to make harmful gas and tiny waste residue in the aluminium liquid discharge. Meanwhile, the degassing chamber main body is formed by building a plurality of modular bricks made of non-stick aluminum hard materials, so that the degassing chamber can be baked before building, cracking caused by long-term temperature change is effectively avoided, and the generation of poor characteristics of the castable is prevented.
Description
Technical Field
The utility model relates to an online refining device of aluminium liquid that uses before continuous and semicontinuous casting of aluminium base, in particular to online refining device's of aluminium liquid degassing chamber.
Background
At present, when aluminum blanks with higher casting quality requirements are cast at home and abroad, an aluminum liquid online refining device is required to be arranged on a flow channel in front of a casting machine, and the aluminum liquid is subjected to online degassing, deslagging and other purification treatments, and sometimes the aluminum blank is added with the functions of adding, stirring, filtering, heating, preserving heat and the like of a grain refiner. At present, the following two aluminum liquid online refining devices are commonly used at home and abroad:
1. the graphite rotor type online refining device utilizes the rotation of one or more graphite rotors in the aluminum liquid to break high-purity nitrogen (argon) sprayed from the graphite rotors, increases the quantity of bubbles, enlarges the acting area of the bubbles, prolongs the retention time of the bubbles in the aluminum liquid, and simultaneously, the graphite rotors can effectively stir the aluminum liquid to increase the uniformity of a grain refiner. 2. Air brick type online refining device: the micro-porous air bricks arranged at the bottom of the degassing box penetrate the small bubbles to naturally rise, refining is carried out by electromagnetic stirring, and the rising process of dispersed bubbles can have a little stirring effect on the aluminum liquid. The degassing chamber in the two devices adopts an integral chamber type structure, and the degassing chamber cracks due to long-term temperature change, so that the castable has poor characteristics.
Disclosure of Invention
An object of the utility model is to provide an online refining plant's of aluminium liquid degassing chamber, degassing chamber adopt a plurality of on-stick aluminium hard material to make the module brick and build thoroughly and form, can carry out to build the prebaking, and effectively avoided because of the produced fracture of long-term temperature change, prevent that the bad characteristic of pouring material from producing.
The technical scheme of the utility model is that: the utility model provides an online refining plant's of aluminium liquid degassing chamber, includes degassing chamber main part, its characterized in that: the degassing chamber main body is formed by building a plurality of module bricks made of non-stick aluminum hard materials, a degassing chamber water inlet is formed in the upper portion, a deslagging port is formed in the bottom portion, a turbulence brick is arranged in the degassing chamber, a diving brick is arranged at the degassing chamber water inlet, and a nano bubble refining brick and an air supply pipe are arranged at the bottom portion of the degassing chamber.
The utility model discloses when using, high-purity hydrogen or argon gas are refined the brick dispersion by the air supply pipe in getting into the degasification room, stir down with the vortex brick through the nanometer bubble, form irregular aluminium and flow, and dispersed bubble is broken once more, carries out complete abundant combination with aluminium water to make harmful gas and tiny waste residue in the aluminium liquid discharge. Meanwhile, the degassing chamber main body is formed by building a plurality of modular bricks made of non-stick aluminum hard materials, so that the degassing chamber can be baked before building, cracking caused by long-term temperature change is effectively avoided, and the generation of poor characteristics of the castable is prevented.
