The top of the handle vertical pipe is provided with steps (6), and the lower cover is sleeved outside the handle vertical pipe and arranged below the steps at the top of the handle vertical pipe.

The support system includes a base (50), a riser (60) coupled to the base, a support (70) coupled to the riser and a locking mechanism (100) positioned at a distal end of the riser.

The vertical pipe comprises a middle pipe (21) and a seat post (22).

A cover (14) for the upper end of an exhaust stack pipe (10) comprises a curved cover pipe (16) of greater diameter than the stack pipe (10).

The standpipe further includes a gravity trap that is configured to inhibit formed impurities from traveling from at least a portion of the standpipe through the first end portion of the standpipe.

The standpipe is cooled by flowing a cooling medium through a passageway that extends along an external surface of the standpipe.

The push tube (3) can be guided and longitudinally displaced inside the upright tube (1).

The lower end of the upright pipe is bed leg.

The apparatus also comprises a vertically disposed pH adjustment tube (5).

A valve attached to the standpipe above the magnetic float allows controlled ventilation of the gas in the standpipe and thus in the piping system.

A central standpipe (2) is arranged over the cleaned liquid outlet (14), and the filter insert (3) is plugged onto the standpipe (2).

A standpipe attached to the pipe fitting houses a magnetic float.

The cover pipe (16) is shaped to prevent rain from falling directly onto the end of the stack pipe.

A kingpin lock includes a vertically-oriented tube with a conical shell formed by a plurality of gussets projecting radially from the tube.

The apparatus comprise a first glass melt station and a standpipe.
