Detailed Description

The invention is further described with reference to the following figures and detailed description.

As shown in fig. 1-3, a smelting furnace converter tap hole plugging device comprises a fiber plugging assembly and a launder 16 arranged at the output end of the tap hole, wherein the fiber plugging assembly comprises a fiber plugging head 1, an inclined steel bar 2 and a horizontal pipe 3 which are sequentially connected, a handle A4 is arranged on the horizontal pipe, and the fiber plugging head is positioned below the horizontal pipe; the runner is sequentially provided with a first support 10 and a second support 12, the left side and the right side of the upper side of the runner are respectively provided with a support plate 5 which is spliced with the first support and the second support, and the support plates are vertically provided with slots for accommodating the first support or the second support; the support groove 13 for containing the horizontal pipe is vertically formed in the first support, the nut 14 matched with the support groove is fixedly welded on the second support, the pushing screw rod 8 penetrates through the nut, the outer end of the pushing screw rod is provided with a rotating handle 15, and the inner end of the pushing screw rod can abut against the outer end of the horizontal pipe.

In this embodiment, the first support and the second support are both L-shaped frames, the horizontal part of each L-shaped frame is inserted into the support plate, and the tail end of the vertical part of each L-shaped frame is hinged to the support 11 fixedly mounted on the outer side wall of the runner.

In this embodiment, a handle B7 is mounted on the horizontal portion of the L-shaped frame.

In this embodiment, a push block 6 is installed on one of the inner end of the pushing screw rod or the outer end of the horizontal tube.

The use steps are as follows:

and (3) plugging an aluminum outlet: sleeving the plugging cap on the fiber plugging head, carrying the handle A by hand, and placing the fiber plugging component in the supporting groove of the first bracket; knocking the tail end of the handle A, and driving the fiber plugging head to move along the horizontal direction by the horizontal pipe, so that the fiber plugging head is inserted into the flow port; the rotating handle is rotated to enable the inner end of the pushing screw rod to push the horizontal pipe, so that the fiber plugging head of the fiber plugging assembly presses the flow inlet and completely plugs the flow outlet, and the flow outlet is completely plugged at the moment, thereby effectively preventing the leakage of aluminum liquid.

Aluminum discharging operation steps: rotating the rotary handle to enable the pushing screw rod to be separated from the horizontal pipe, and moving away the fiber plugging device to enable the fiber plugging head not to compress the flow port any more; tapping the front end of the handle A by using an iron hammer, and driving the fiber plugging head to move along the horizontal direction by using the horizontal pipe so as to separate the fiber plugging head from the flow port; lifting the fiber plugging component out of the first support by the aid of the carrying handle A, and placing the fiber plugging component elsewhere; and rotating the first bracket and the second bracket to be not above the runner.

This device handle A and first support make stifled fine head insert the mouth of a river to make stifled fine head off tracking not, reuse top pushes away the lead screw and makes stifled fine head and the mouth of a river tightly laminate, effectively guarantees that the metal liquid can not reveal, and the articulated mounting means of first support, second support also guarantees can not influence the transportation of metal liquid.
