Description
Technical Field
The utility model relates to an aluminium liquid degassing unit, concretely relates to graphite rotor mechanism.
Background
In the production of aluminum water, hydrogen gas is generated in the aluminum water, and the hydrogen gas exists in the aluminum water, and bubble holes remain in the aluminum piece when the aluminum piece is cast by the aluminum water, so that the strength of the aluminum piece is reduced, and therefore, the hydrogen gas in the aluminum water needs to be removed to ensure the quality of the aluminum piece produced by the aluminum water. The aluminum degassing equipment needs to use a graphite rotor, and the purification treatment method for removing hydrogen and oxide inclusions in the aluminum liquid by using the rotation of the graphite rotor to blow inert gas is the most advanced aluminum liquid treatment method internationally at present. The prior graphite rotor mechanism is generally inserted below the liquid level of aluminum liquid and only has a single graphite pipe, which may have the problems of insufficient and uneven stirring, and insufficient contact area and contact time of bubbles and partial aluminum alloy liquid.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to above problem, make research improvement, provide a graphite rotor mechanism.
In order to achieve the purpose, the utility model provides a graphite rotor mechanism, which comprises a motor, an argon pipe and a graphite rotor, wherein the motor is connected with the argon pipe through a connecting seat, the other end of the argon pipe is connected with the graphite rotor, and the other end of the graphite rotor is provided with three stirring heads in a regular triangular arrangement mode; an argon inlet is formed in the argon pipe; and an air channel communicated with an argon pipe is arranged in the graphite rotor, and the air channel branches to three gas outlets at the bottom of the stirring head.
As the preferred arrangement of the utility model, an anti-oxidation coating is prepared on the surface of the graphite rotor.
As the optimal arrangement of the utility model, the position of the graphite rotor, which is positioned at the liquid level of the aluminum liquid during the work, is provided with the erosion-resistant and oxidation-resistant ceramic sleeve.
The utility model has the advantages that: the device has higher local tangential speed and uniform speed distribution, more fully and uniformly stirs the aluminum melt, can cut argon bubbles smaller, and improves the purification treatment efficiency for removing hydrogen and oxide inclusions in the aluminum liquid.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.
According to fig. 1-2, the utility model provides a graphite rotor mechanism, including motor 1, argon gas pipe 2 and graphite rotor 3, motor 1 connects argon gas pipe 2 through connecting seat 4, graphite rotor 3 is connected to the other end of argon gas pipe 2, the mode that the graphite rotor 3 other end was arranged for according to regular triangle sets up three stirring head 5, specifically speaking, graphite rotor 5 keeps away from the one end design of argon gas pipe has radial convex disc structure, three stirring head 5 promptly set up in on the disc structure, further speaking, the triangle-shaped circumscribed circle diameter ratio graphite rotor 3 diameter that three stirring head 5 centre of a circle confirmed is a plurality of times bigger, under the motor rotational speed does not change, than current design, improved the tangential velocity of stirring head, and meanwhile, the form of arranging of regular triangle makes the velocity distribution more even; an argon inlet 6 is formed in the argon pipe 2; be equipped with the air duct with argon gas pipe 2 intercommunication in the graphite rotor 3, the air duct branch is to three 6 bottom gas outlets in stirring head.
Further, graphite is easily oxidized and easily broken after oxidation, so that an oxidation-resistant coating is prepared on the surface of the graphite rotor 3. And a scouring-resistant and oxidation-resistant ceramic sleeve 7 is arranged at the position of the graphite rotor 3 on the liquid level of the aluminum liquid when the graphite rotor 3 works, so that the graphite rotor 3 is prevented from being broken after being excessively worn at the contact part with the liquid level of the aluminum liquid.
The utility model discloses the working process: the utility model discloses install on aluminium liquid degasser, its graphite rotor stretches into in the aluminium liquid, and the during operation, motor drive argon gas pipe rotates, and the argon gas pipe lets in the argon gas to aluminium liquid simultaneously, flows from graphite rotor bottom gas outlet, and graphite rotor rotates and stirs the breakage to the argon gas bubble, obtains thin argon gas bubble, takes away hydrogen and impurity in the aluminium liquid.
The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
