Abstract
The utility model relates to a metal smelting and casting tool, and particularly relates to a threaded connection silicon nitride degassing rotor. The threaded connection silicon nitride degassing rotor comprises an impeller and a rotating rod, wherein the rotating rod is formed by threaded connection of multiple short rotating rods, the short rotating rod on the lowest end is in threaded connection with the impeller, and the bottom of the impeller is provided with blades which are radially arranged. The threaded connection silicon nitride degassing rotor realizes easiness in production and processing and convenience in packaging and transportation; if the rotating rod is locally damaged, only the subsection rotating rod needs to be replaced without influencing the whole body; and the threaded connection silicon nitride degassing rotor overcomes the shortcomings that the rotating rod of a conventional silicon nitride rotor is long and difficult to produce and machine, the production cost is high, the packaging and transportation are inconvenient, and the whole is scrapped due to local damage.
Description
Technical field:
The utility model relates to a kind of Metal Melting casting tool, and particularly a kind of silicon nitride that is threaded removes air rotor.
Background technology:
Melt degasification when silicon nitride is used for aluminium and alloy refining except that air rotor, existing silicon nitride removes the bull stick that air rotor comprises a hollow, and the bull stick end is equipped with impeller.The bull stick length of silicon nitride rotor is greater than 750mm at present, and difficulty is produced and processing, and yield rate is low, and production cost is high, and integrated firing is difficult to finish.Because the body of rod is longer, packing, transportation inconvenience.Local damage, integral body all will be scrapped, and loss is serious.
The utility model content:
The technical problems to be solved in the utility model provides a kind of silicon nitride that is threaded and removes air rotor, and this instrument has realized that process for processing is easy, and packed and transported is convenient, and local bull stick damage only needs to change the segmentation bull stick does not influence integral body.It is long to have overcome existing silicon nitride rotor bull stick length, process for processing difficulty, production cost height, packed and transported inconvenience, local damage, the whole deficiency that all will scrap.
Technical solution adopted in the utility model is: a kind of silicon nitride that is threaded removes air rotor, comprises impeller and bull stick; Bull stick adopts the short bull stick of more piece to be threaded and forms, and short drill pipe is threaded with impeller bottom, and wheel bottom has the blade that radially is provided with radially.
Bull stick is divided into bull stick and last bull stick two joints down.
The beneficial effects of the utility model are: bull stick of the present utility model is because the mode that has adopted the short bull stick of more piece to be threaded and to form, thereby having process for processing easily and packed and transported effect easily, local bull stick damages only needs replacing segmentation bull stick not influence integral body.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of silicon nitride that is threaded removes air rotor, comprises impeller 1 and bull stick; Bull stick 2 and last bull stick 3 were threaded and form under bull stick adopted, and it is long to be connected to 1200mm, adapts to all present aluminium melting furnaces.Following bull stick 2 is threaded with impeller 1, and the blade 4 that radially is provided with radially, similar stiffening web are arranged at impeller 1 bottom.Refining gas enters impeller 1 from the bull stick pore open air chamber arrives impeller 1 edge by centrifugal force, and the blade 4 that is rotated is smashed, and forms the required small bubbles of aluminum melt degassing.
If certain part in use of the present utility model is damaged, then can open and be threaded, carry out local replacing, do not need whole replacings.
By factory to the user in transit the short bull stick of more piece open packing respectively, again integral body is removed air rotor before the use and couples together.
Be understandable that, more than about specific descriptions of the present utility model, only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
