Background
In the casting field, the price of raw materials is greatly fluctuated, the rising of the price leads to the great increase of the production cost, the requirement on the product quality is higher and higher, the market competition is increasingly violent, enterprises face the product price competition, the profit margin is obviously reduced, and the operation and profit gaining capacity of the enterprises is increasingly difficult.
The safety department has more and more strict audit on the implementation situation of the safety production of the enterprise, the safety production is a necessary condition for the smooth operation of the enterprise, and the safety production of the enterprise can be guaranteed only by a designed safety production tool.
With the development of the wind power industry towards offshore wind turbines, the castings tend to be large in size and light in weight. In the pouring process, in order to improve the operation efficiency and rationality of operation, the pouring in a leaky ladle is a common operation mode.
The leaky ladle pouring is generally used for solving the problems of limitation of traveling crane height limitation or limitation of electric furnace smelting capacity and the like, so that the leaky ladle pouring operation can make up the problem that the traveling crane height limitation affects the pouring of a suspended ladle due to the large size of a heavy hub, or the rated capacity of an electric furnace is not enough for direct pouring, and the operation in the process of multi-ladle pouring needs to be matched, and the adopted mature operation mode is adopted.
However, the leakage ladle casting is not suitable for artificial stream inoculation due to high risk of manual stream discharge operation, and graphite spheroidization is assisted only by the inoculation block in the pre-buried ladle, so that the graphite form stability of the casting is poor, and the spheroidization rate and the roundness are poor particularly at the thick part of the casting.

The device is suitable for inoculation work during pouring of a leaky ladle, ensures operation safety, improves working efficiency, reduces cost and improves efficiency. The device specifically comprises:
a inoculant feeding device for ladle leakage stream inoculation of large wind power hub castings comprises a support and a storage barrel for containing inoculant, wherein the storage barrel is arranged on the support; the discharge port of the storage barrel is connected with a feeding conduit. Also comprises an air tap; the air inlet of the air tap is connected with a high-pressure air source through an air pipe, and an adjustable air valve is connected to the air inlet of the air tap;

The device is designed according to the idea that a guide pipe is adopted to guide the inoculant in the far-end storage barrel to a pouring gate of the sand box. Because the conduit is longer, in order to make the inoculant flow smoothly, high-pressure air is adopted to blow the inoculant in the conduit. The adjustable valve is convenient for controlling the feeding amount, the adjustable air pressure can control the feeding speed, and the feeding amount and the feeding time are more accurate after the adjustable valve and the feeding speed are combined.
Further, the feeding conduit is inclined, and the height of the discharge opening of the feeding conduit is lower than that of the feed opening of the feeding conduit. This structure contributes to smooth flow of materials.

the tail end of the discharge pipe is connected with an elbow; a feeding port is arranged on the side wall of the head part of the feeding conduit, and the elbow is connected with the feeding port of the feeding conduit; the end part of the head part of the feeding conduit is connected with an end plate, and the air outlet of the air tap is connected to the end plate.
Under the structure, the inoculant falls into the discharge pipe by means of self gravity, and the discharge pipe is provided with an adjustable valve (only by adopting the existing butterfly valve and the like). In order to make the material flow smooth and avoid material accumulation on the wall of the conduit, the feed inlet of the feeding conduit is arranged on the wall of the conduit, and meanwhile, the material flow direction is changed by adopting an elbow, wherein the direction of the elbow is the discharging direction of the feeding conduit. And high-pressure air is blown to the discharge hole of the feeding guide pipe from the end part of the feeding guide pipe, so that the smoothness of material flow is further improved.
The high pressure air source may be an air compressor with an air reservoir. The air pipe of the device is connected with the air outlet of the air storage tank. At the production site, the system can also be directly connected to a common gas source on site.
