[0024] The specific embodiment of the inoculant feeding device for core yarn production of the present application is,

[0025] As Figures 1-4 shown: the inoculant feeding device for core yarn production, comprising a molten iron container 1, an inoculant container 2 and a ladle 3, a molten iron outlet pipe 4 is arranged on the molten iron container 1, a first electric valve 7 is arranged on the molten iron outlet pipe 4, a special-shaped pipe 5 is arranged on the outlet end of the molten iron outlet pipe 4, the special-shaped pipe 5 is used to make the molten iron and the inoculant enter the ladle 3 at the same time after mixing and dissolving, saving the mixing and dissolving time in the ladle 3, the end of the special-shaped pipe 5 away from the molten iron outlet pipe 4 is located above the ladle 3, an outlet pipe 6 is arranged on the inoculant container 2, a second electric valve 8 is arranged on the outlet pipe 6, one end of the outlet pipe 6 is communicated with the side of the special-shaped pipe 5 facing the inoculant container 2.

[0026] The molten iron container 1, the inoculant container 2 and the ladle 3, and the installation positions and installation manners of the three are prior art, and will not be described here again. In addition, the first electric valve 7 can control the speed and flow of the molten iron flowing out of the molten iron outlet pipe 5, and the second electric valve 8 has the same effect as the first electric valve 7.

[0027] Further, the special-shaped pipe 5 includes a first wave-shaped curved section 501 arranged transversely and a second wave-shaped curved section 502 arranged longitudinally. The first wave-shaped curved section 501 includes a plurality of U-shaped sections 5011 in inverted U shape with openings facing downward. In this embodiment, the number of U-shaped sections 5011 is three.

[0028] In this embodiment, the number of discharge pipes 6 is three. One end of each of the three discharge pipes 6 is arranged on the bottom of the inoculant container 2 at equal intervals, and the other end is arranged on the side of the U-shaped section 5011 facing upward.

[0029] The second electric valve 8 is arranged on each of the three discharge pipes 6. The amount of inoculant discharged from each of the three discharge pipes 6 decreases from left to right, which facilitates the control of the flow of inoculant into the special-shaped pipe 5. The control and adjustment of the molten iron outlet pipe 4 and the discharge pipe 6 by the first electric valve 7 and the second electric valve 8 respectively can make the molten iron and the inoculant in the ladle 3 match.

[0030] In order to completely mix the molten iron and the inoculant in the special-shaped pipe 5, the first blocking unit and the second blocking unit for mixing the molten iron and the inoculant are arranged in the U-shaped section 5011.

[0031] The first blocking unit includes three blocking columns 9 arranged at equal intervals.

[0032] The second blocking unit includes an iron ring 10. A plurality of impact columns 11 are arranged in the iron ring 10 at equal intervals in the longitudinal direction. In this embodiment, the number of impact columns 11 is nine. A plurality of fixing columns 12 for fixing the impact columns 11 are arranged on the inner circumferential surface of the iron ring 10. The number of fixing columns 12 is eighteen. The lengths of the eighteen fixing columns are different. The eighteen fixing columns fix the nine impact columns 11 in the iron ring 10 at equal intervals, so that the nine impact columns 11 are arranged in the form of a rectangular array in the iron ring 10. After the fixing of the impact columns 11, the fixing columns 12 are arranged in a mesh shape.

[0033] The blocking column 9 is arranged transversely, the impact column 11 is arranged longitudinally, after the molten iron and the inoculant enter into the special-shaped pipe 5, the impact of the blocking column 9 is used to first disturb (that is, mix) the molten iron and the inoculant, then the impact column 11 and the fixed column 12 are used to secondly disturb (that is, secondly mix) the molten iron and the inoculant, the two disturbances make the inoculant and the molten iron fully mixed, then the second wave bending section 502 is used to prolong the time of the molten iron and the inoculant entering into the molten iron ladle 3, so that the molten iron and the inoculant are fully dissolved, after the molten iron and the inoculant after being dissolved enter into the molten iron ladle 3, the molten iron and the inoculant can be directly used, the time of manual stirring is saved, the time of the molten iron and the inoculant being dissolved can be reasonably controlled through the special-shaped pipe 5, and the molten iron and the inoculant reach the optimal dissolution time.

[0034] The exhaust pipe 13 which is in communication with the inside of the discharge pipe 6 is arranged on the discharge pipe 6 and inclined, the exhaust pipe 13 can make the inside of the discharge pipe 6 have normal air pressure, and ensure that the inoculant can normally enter into the special-shaped pipe 5.

[0035] The second specific embodiment of the inoculant feeding device for the cored wire production of the present application,

[0036] The difference between the second embodiment and the first embodiment is that the number of the U-shaped sections is four, the number of the discharge pipes is four, and the diameter of the special-shaped pipe is greater than that of the special-shaped pipe in the first embodiment, so that the flow entering the molten iron ladle can be increased, correspondingly, in order to reach the optimal dissolution time, the length of the special-shaped pipe needs to be prolonged, and in actual production, the length and the diameter of the special-shaped pipe and the number of the discharge pipes are determined according to the production situation.

[0037] The working principle of the present application is as follows: when the molten iron and the inoculant need to be discharged into the molten iron ladle 3, first, the flow of the molten iron out of the molten iron outlet pipe 4 is adjusted through the first electric valve 7, and the discharge amount of each discharge pipe 6 is adjusted through the second electric valve 8, after the adjustment is completed, the molten iron in the molten iron container 1 and the inoculant in the inoculant container 2 are discharged into the special-shaped pipe 5, the first blocking unit and the second blocking unit in the special-shaped pipe 5 are used to mix and dissolve the molten iron and the inoculant in the pipe, and finally the molten iron and the inoculant are discharged into the molten iron ladle 3, the whole process basically does not need manual participation and manual stirring, the working safety of workers is ensured, and the inoculation effect of the inoculant entering into the molten iron ladle 3 is also improved.
