Upper air intake burner with cover plate

一种带盖板的上进风燃烧器

Abstract

The utility model discloses an upper air intake burner with a cover plate, which relates to a burner. At present, a core pulling process is adopted by ejectors, machining is adopted for the communication of a distribution chamber, machining is inconvenient, and the efficiency is low. The upper air intake burner is characterized in that outer-circle mixing chambers are a first outer-circle mixing chamber, a second outer-circle mixing chamber and third outer-circle mixing chambers, the first outer-circle mixing chamber communicates with the middle of the second outer-circle mixing chamber, the left end and right end of the second outer-circle mixing chamber communicate with the two symmetrically arranged third outer-circle mixing chambers, the opening of the second outer-circle mixing chamber is forward, and the cover plate is arranged at the opening to close the second outer-circle mixing chamber; the third outer-circle mixing chambers are provided with upward outer-circle gas outlets. The technical scheme not only can ensure the smoothness and sealing property of the inner wall of an ejector, but also can solve the problem that the gas passage is hard to machine, the upper air intake burner is convenient to machine, and can be produced in one step by a mould, and the technological process is simplified.
一种带盖板的上进风燃烧器,涉及一种燃烧器。目前引射器采用抽芯的工艺,分配室的联通采用机加工,加工不方便,且效率较低。本实用新型特征在于:所述的外环混合腔包括第一外环混合腔、第二外环混合腔、第三外环混合腔,所述的第一外环混合腔与第二外环混合腔中部相通,第二外环混合腔的左右两端与两对称设置的第三外环混合腔相通,第二外环混合腔向前开口,开口处设有盖板以封闭第二外环混合腔;所述的第三外环混合腔设有向上的外环出气口。本技术方案既可保证引射器内壁的光滑和密封性,又可解决燃气通道加工难的问题,其加工方便,可通过模具一次获得,减少工艺过程。
