Abstract
The utility model discloses a muffle pipe air inlet structure of an atmosphere protection mesh belt furnace. The muffle pipe air inlet structure of the atmosphere protection mesh belt furnace comprises a plurality of air inlet pipes which extend into the inside of the muffle pipe. Air inlets are formed on the air inlet pipes which are fixed on the top positions inside the muffle pipe through clamps. The air inlets on each air inlet pipe comprise a plurality of air inlets I, a plurality of air inlets II and a plurality of air inlets III, wherein air inlets I are in vertically downward directions, acute angles are formed between the air inlets II and the vertically downward directions and are inclined to the left and acute angles are as well formed between the air inlets III and the vertically downward directions and are inclined to the right. According to the air inlet structure arranged on the atmosphere mesh belt furnace, the air inlet of a temperature section and a temperature cooling section of the furnace, the muffle pipe air inlet structure of the atmosphere protection mesh belt furnace has the advantages of ensuring the uniformity and stability of the atmosphere inside the furnace, being capable of keeping the temperature uniform in the muffle furnace and ensuring the normal operation of production.
Description
Technical field
The utility model relates to a kind of muffle tube air intake structure of atmosphere protection meshbeltfurnace.
Background technology
Adopt of the air feeder structure of the muffle tube of atmosphere protection meshbeltfurnace established some air admission holes in air inlet pipe more; and these air admission holes or random arranging; only be arranged on the straight line direction; the easy like this atmosphere when causing air inlet in the burner hearth can not keep uniform and stable; cause in the Muffle furnace temperature can not homogeneous, thereby production has been caused considerable influence.
Summary of the invention
The purpose of this utility model is to provide a kind of muffle tube air intake structure that can guarantee the atmosphere protection meshbeltfurnace that the interior air inlet of furnace muffle tube is uniform and stable.
The muffle tube air intake structure of atmosphere protection meshbeltfurnace of the present utility model; comprise that level stretches into several air inlet pipe of muffle tube inside; described air inlet pipe is provided with air admission hole; described air inlet pipe is fixed on tip position in the muffle tube by clip, and the air admission hole on described each air inlet pipe includes straight down some air admission holes one, in vertical direction with some air admission holes two on acute angle angle and an oblique left side and in vertical direction with some air admission holes three on acute angle angle and the oblique right side.
Angle between described air admission hole two and the vertical direction equals the angle between air admission hole three and the vertical direction.
Angle between described air admission hole two and the vertical direction and the angle between air admission hole three and the vertical direction are 45o.
Horizontal range between the described adjacent air admission hole is 30-60mm.
Air intake structure of the present utility model is used on the atmosphere meshbeltfurnace, and burner hearth heat up section and the air inlet of high temperature temperature descending section have guaranteed the uniform and stable property of atmosphere in the burner hearth, makes that temperature keeps homogeneous in the Muffle furnace, has guaranteed the normal operation of production.
