Detailed Description

The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Fig. 1 shows an implementation form of the present invention, which includes:

an inoculant container 4, which is internally provided with a containing cavity, wherein inoculant is placed in the containing cavity in advance and can be added with supplementary inoculant at any time according to the feeding condition of the inoculant; the discharging pipe 6 is vertically arranged on the lower end face of the inoculant container 4 and is communicated with the accommodating cavity, and inoculant flows out of the accommodating cavity through the discharging pipe 6; the rotating flow groove is rotatably connected with the lower end of the discharge pipe 6 and is communicated with the discharge pipe 6, the rotating flow groove rotates 360 degrees by taking the vertical center line of the discharge pipe 6 as a rotating shaft, inoculant enters the rotating flow groove through the discharge pipe 6 and flows into the ladle 3 in a rotating and dispersing mode to be mixed with molten iron, so that the inoculant is dispersed more uniformly, the inoculation effect is obviously enhanced, meanwhile, the inoculant and the molten iron are synchronously fed, the inoculant is prevented from being mixed with the molten iron too early, the effect of the inoculant is not influenced, and the feeding amount of the inoculant can be effectively reduced on the premise of not influencing the inoculation effect; the rotary launder is composed of a vertical flow trough part 11 and an inclined flow trough part 13, the inclined flow trough part 13 is connected to the discharge pipe 6 through the vertical flow trough part 11, the inclined flow trough part 13 and the vertical flow trough part 11 are integrated, and the upper end of the vertical flow trough part 11 is rotatably connected to the lower end of the discharge pipe 6.

In the technical scheme, the casting ladle 3 is of an accommodating cavity structure with an upward opening, and the opening covers the lower end of the inclined flow groove part 13, so that the inoculant completely falls into the casting ladle 3 when the inoculant rotationally flows out from the inclined flow groove part 13, and the inoculant is uniformly dispersed in the casting ladle 3, and the inoculation effect is enhanced.

In the technical scheme, the upper end of the casting ladle 3 is also provided with a molten iron launder 2, molten iron flows into the casting ladle 3 from the molten iron ladle 1 through the molten iron launder 2, and meanwhile, the inoculant is uniformly dispersed in the molten iron, so that a good inoculation effect is achieved.
