一种精粉炉烧火装置制造方法及图纸

本实用新型专利技术涉及一种精粉炉烧火装置，包括燃烧室、燃烧室内的上炉膛和设置在上炉膛底端处的下炉膛，上炉膛的底板上开有与下炉膛连通的通孔，通孔内壁沿圆周设置有支撑座，支撑座上设有烧火嘴，烧火嘴通过管道连接天然气，上炉膛内还连接助燃气体，燃烧室的外圈包裹有保温层，保温层的外圈包裹有隔热层，燃烧室顶端设有排烟道。通孔内的支撑座直接安装放置烧火嘴，安装方便，且从下炉膛方向活动安装在通孔内，便于从下炉膛的火道检修口对支撑座进行拆卸和安装，便于实现对烧火嘴的检修和更换；上炉膛的上膛口和下炉膛的下膛口分别采用上膛门和下膛门封闭，可有效避免其他杂质混入炉膛，同时避免氧气外泄氧化锌粉，提高燃烧室的安全性。

A Kind of Burning Device for Fine Powder Furnace

The utility model relates to a burning device for a fine powder furnace, which comprises a combustion chamber, an upper furnace in the combustion chamber and a lower furnace arranged at the bottom end of the upper furnace. The bottom plate of the upper furnace is provided with a through hole connected with the lower furnace. The inner wall of the through hole is provided with a support seat along the circumference, and a burner is arranged on the support seat. The burner is connected with natural gas through a pipeline, and the upper furnace is also connected with a combustion aid gas. The outer ring of the chamber is wrapped with a thermal insulation layer, the outer ring of the thermal insulation layer is wrapped with a thermal insulation layer, and the top of the combustion chamber is provided with a flue. The supporting seat in the through hole is directly installed and placed with the burner, which is convenient to install, and is movably installed in the through hole from the direction of the lower furnace. It is convenient to disassemble and install the supporting seat from the channel maintenance mouth of the lower furnace, and to realize the inspection and replacement of the burner. The upper and lower ports of the upper and lower hearths of the upper furnace are sealed by the upper and lower ports respectively, which can effectively avoid the mixing of other impurities. The safety of combustion chamber can be improved by avoiding the leakage of zinc oxide powder by oxygen into the furnace.

【技术实现步骤摘要】
一种精粉炉烧火装置
本技术涉及一种炼锌装置，尤其是涉及一种精粉炉烧火装置。
技术介绍
锌粉具有极强的着色力和遮盖力，常用作油漆的颜料和橡胶的填充料。锌粉是以锌锭为原料通过锌粉炉加工制作的，锌粉在无机化工原料制备、金属提取、钢铁的防腐以及电源、火箭燃料等领域有着广泛应用。随着工业的发展和新技术的开发，锌粉的用量日益增大，尤其超细锌粉的需求量增长迅速。现有的锌粉炉燃烧装置的烧火嘴大多是放置在炉膛内，然后通过耐高温材料将烧火嘴周边密封固定住，这样的方式，在对烧火嘴进行更换时，只能破坏原有的固定方式，费时费力，给烧火嘴的维修和更换带来很大不便；且燃烧装置加热过程中，炉内的气体容易由于混合其他杂质，被排出容易污染空气。
