Embodiment 2

[0018] Embodiment 2: The difference from Embodiment 1 is that it also includes a base 11, which is located on the inner surface of the end cover, and the base is used to support the hollow movable rod to enhance the overall stability and prevent the hollow movable rod from breaking due to stress .

Embodiment 3

[0019] Embodiment 3: The difference from Embodiment 1 is that the sleeve is slidably connected to the free end of the hollow movable rod, and the free end surface of the hollow movable rod is provided with a raised first stopper. The limiting part prevents the sleeve from being separated from the hollow movable rod when sliding.

Embodiment 4

[0020] Embodiment 4: The difference from Embodiment 1 or Embodiment 3 is that the hollow movable rod is provided with a raised second limiting part, and the sleeve will be positioned between the first limiting part and the second limiting part. slide between. The limiting part prevents the sleeve from being above the valve port of the slag discharge valve when sliding.

[0021] The purpose of Embodiments 3 and 4 is to be able to adjust the position between the vent hole and the crushing part receiving groove, thereby adjusting the exposure degree of the crushing part. For example, when the sleeve slides to the second stop, the vent hole and The crushing parts at the rightmost end are closer, and the crushing parts at this end are subjected to greater air pressure, and more parts are exposed, while the crushing parts at the leftmost end are farther away, and the crushing parts at this end are subjected to less air pressure, and more parts are exposed. There are relatively few ...

Abstract

The invention discloses a slag discharge pipeline for rapidly removing pyrite slag and a method for using the same, comprising: a slag discharge pipeline; a slag discharge valve (1) connected to the slag discharge pipeline, and a slag discharge valve (1) located above the slag discharge valve Inspection window (2); hollow pipe body (3); end cover (4); radial through hole (5); hollow movable rod (6); sleeve (7); crushing part receiving groove; crushing part (8 ); the annular space (9), the annular space is opened between the surface of the hollow movable rod and the crushing part accommodation groove, and communicates with the crushing part accommodation groove; the ventilation hole (10), the ventilation hole is opened in the coverage area of ​​the annular space The surface of the hollow movable rod. The beneficial effect of the present invention is that through the cooperation of the external air source, the hollow movable rod, the crushing part, and the end cover, the crushing part can extend above the valve port of the slag discharge valve for rotary cutting, and the agglomerated pyrite slag is broken, The required time is short and does not affect the normal production. The safety of operation is also high.

Description

technical field [0001] The invention relates to the field of pyrite production, in particular to a slag discharge pipeline for removing pyrite slag and a use method thereof. Background technique [0002] The high-temperature pyrite slag (650-820°C) produced during the boiling process of pyrite ore needs to be discharged through the control valve on the high-temperature slag discharge pipe. In actual production, due to reasons such as furnace conditions and raw materials, agglomerated pyrite slag and refractory foreign matter of different sizes are often formed during the boiling process. Because the high-temperature slag discharge valve has a limited diameter of DN200cm, it is easy to block the high-temperature discharge valve. If this happens, the production of the roaster must be suspended for thermal insulation treatment. At the same time, maintenance personnel should be organized to disassemble the high-temperature slag valve and clean up foreign objects in the slag disc...
