Detailed Description

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: pushing off slag stopper body 1, guide post 2, arc wall 3, clean pole 4 of bar, clean pole 5 of arc, moving motor 6, clean piece 7, screw thread 8, first telescopic link 9, second telescopic link 10.

An environment-friendly converter tapping hole plastic slag stopper, an embodiment of which is shown in figures 1 and 2. Including pushing off the slag stopper body 1 and two clean mechanisms, pushing off the slag stopper body 1 and establishing to the top of the staff shape, the three arc wall 3 of side circumference equipartition of pushing off the slag stopper, the bottom threaded connection of pushing off the slag stopper body 1 has guide post 2, welded movable motor 6 in the guide post 2, the output shaft of movable motor 6 passes the center of pushing off the slag stopper body 1, the upper end of the output shaft of movable motor 6 is located the pushing off the slag stopper outside, the welding has bar cleaning rod 4 on the 6 output shafts of the outside movable motor of pushing off the slag stopper body 1, bar cleaning rod 4 and the laminating of pushing off the slag stopper top surface. The part of the output shaft of the movable motor 6, which is positioned in the slag blocking plug, is provided with a thread 8, a cleaning groove which can accommodate the cleaning mechanism to move up and down is arranged in the slag blocking plug, the cleaning groove is communicated with the arc-shaped groove 3, and the arc-shaped groove 3 and the cleaning groove are communicated to form shielding curtains symmetrically.

The embodiment is as shown in fig. 3, clean mechanism includes the clean piece 7 with 8 threaded connection of screw thread on the output shaft of mobile motor 6, clean 7 circumference equipartitions of piece are with the telescopic link of 3 quantity unanimities of arc wall, the telescopic link includes first telescopic link 9 and second telescopic link 10, the one end and the clean 7 welding of piece of second telescopic link 10, first telescopic link 9 is located the inside of second telescopic link 10, the one end and the clean 5 welding of arc that clean piece 7 was kept away from to first telescopic link 9, the diameter of first telescopic link 9 is greater than the width of clean groove and 3 intercommunication departments of arc wall, the free end welding of telescopic link has the clean pole 5 of arc that matches with 3 shapes of arc wall, clean pole 5 of arc is located the surface of arc wall 3, clean pole 5 of arc is laminated with 3 surfaces of arc wall.
