The inside of urceolus is equipped with the inner tube, inner tube cavity sets up, the outside extension of inner tube left side intermediate position has the wind channel, the left end in wind channel extends to the outside of urceolus, be equipped with a wind gap and gas mouth on the wind channel, the inside of inner tube is equipped with the governing pipe of vertical setting, the lateral wall of governing pipe evenly is equipped with a plurality of ventilation hole, the inboard cover of governing pipe is equipped with the secondary air pipe, the bottom of secondary air pipe extends to the outside of urceolus, the left side of secondary air pipe is close to its bottom end position and is equipped with the handle. This natural gas hot-blast stove simple structure, convenient to use, inside regulating pipe and the secondary tuber pipe of having increased of inner tube, make the flow adjustment of combustion-supporting wind more nimble through reciprocating the secondary tuber pipe, enable combustion-supporting wind and gas intensive mixing contact, improve hot-blast air output.

Description

Natural gas hot-blast stove

Technical Field

The utility model relates to a hot-blast furnace technical field, concretely relates to natural gas hot-blast furnace.

Background

Natural gas hot-blast furnace provides the hot-blast air to be used for the drying material, current hot-blast furnace generally only has a wind gap and a gas mouth, in the use, because gas and combustion-supporting wind need suitable proportion, this kind of wind gap, the adjustment of a gas mouth is very difficult nimble, the special ratio is when the burning in later stage, because general gas lets in the volume more, often leads to combustion-supporting wind too few, current combustion-supporting wind and gas all are the equidirectional flow moreover, mix inadequately, the combustion effect is relatively poor.

Disclosure of Invention

The utility model aims at solving the problem and providing a natural gas hot blast stove.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a natural gas hot blast stove comprises an outer barrel, a primary air port, a fuel port, an air duct, a handle, a secondary air pipe, an adjusting pipe and an inner barrel.

The inside of urceolus is equipped with the inner tube, inner tube cavity sets up, the outside extension of inner tube left side intermediate position has the wind channel, the left end in wind channel extends to the outside of urceolus, be equipped with a wind gap and gas mouth on the wind channel, the inside of inner tube is equipped with the governing pipe of vertical setting, the lateral wall of governing pipe evenly is equipped with a plurality of ventilation hole, the inboard cover of governing pipe is equipped with the secondary air pipe, the bottom of secondary air pipe extends to the outside of urceolus, the left side of secondary air pipe is close to its bottom end position and is equipped with the handle.

Further, the shape of the vent hole is circular.

Furthermore, the inner side wall of the adjusting pipe is in contact with the outer side wall of the secondary air pipe, and the secondary air pipe can move up and down in the adjusting pipe.

The utility model has the advantages that: simple structure, convenient to use, inside regulating pipe and the secondary tuber pipe of having increased of inner tube, it is more nimble to make the flow adjustment of combustion-supporting wind through reciprocating the secondary tuber pipe, enables combustion-supporting wind and gas intensive mixing contact, improves hot-blast air output.
