Abstract

本实用新型公开了一种耐磨型稳焰齿,其特征在于,在稳焰齿上开有通孔,燕尾螺栓穿过通孔固定在稳焰齿上,燕尾螺栓的燕尾端位于稳焰齿的迎风侧,开有燕尾槽的耐磨陶瓷安装在燕尾螺栓的燕尾端上。该耐磨耐磨型稳焰齿上安装有耐磨陶瓷,可以有效防止由于煤粉冲刷对稳焰齿的磨损;并且燕尾螺栓与耐磨陶瓷燕尾槽进行互锁,达到稳焰齿和耐磨陶瓷的固定,结构简单稳固、易于装配。

Description

耐磨型稳焰齿
技术领域
本实用新型涉及电站锅炉中煤粉燃烧器的耐磨型稳焰齿。
背景技术
目前市场中,煤粉燃烧器稳焰齿的防磨措施一般都采用铸件,这种防磨措施不能满足防磨要求,煤粉燃烧器稳焰齿经常被磨损,严重影响稳焰齿的稳焰性能。为保证稳焰齿的性能,设计了特殊结构,防止磨损。
实用新型内容
本实用新型的目的是针对现有技术中的缺陷提供一种用于电站锅炉煤粉燃烧器耐磨型稳焰齿。
本实用新型的技术方案是:
一种耐磨型稳焰齿,其特征在于,在稳焰齿上开有通孔,燕尾螺栓穿过通孔固定在稳焰齿上,燕尾螺栓的燕尾端位于稳焰齿的迎风侧,开有燕尾槽的耐磨陶瓷安装在燕尾螺栓的燕尾端上。
本实用新型的有益效果是:耐磨陶瓷安装在稳焰齿的迎风面,可以有效防止由于煤粉冲刷对稳焰齿的磨损;并且燕尾螺栓与耐磨陶瓷燕尾槽进行互锁,达到稳焰齿和耐磨陶瓷的固定,结构简单稳固、易于装配。
附图说明
本实用新型将通过例子并参照附图的方式说明,其中:
图1是本实用新型实施例耐磨型稳焰齿的结构示意图;
图2是图1所示耐磨型稳焰齿K向视图;
图3是图1中耐磨陶瓷的剖视图。
具体实施方式
下面结合附图和实施例对本实用新型进一步说明。
本说明书中公开的所有特征,或公开的所有方法或过程中的步骤,除了互相排斥的特征和/或步骤以外,均可以以任何方式组合。
本说明书(包括任何附加权利要求、摘要和附图)中公开的任一特征,除非特别叙述,均可被其他等效或具有类似目的的替代特征加以替换。即,除非特别叙述,每个特征只是一系列等效或类似特征中的一个例子而已。
一种耐磨型稳焰齿,其结构主要包括稳焰齿4、耐磨陶瓷1、燕尾螺栓2、开槽螺母3等组成。本实用新型是在传统的稳焰齿4迎风面增加耐磨陶瓷1,防止稳焰齿被磨损,耐磨陶瓷1通过下述方式固定在燕尾螺栓4上:耐磨陶瓷1上开有一个大小一定的燕尾槽,采用燕尾螺栓2的燕尾端与燕尾槽配合的方式将耐磨陶瓷1和燕尾螺栓2固定在一起,然后燕尾螺栓2穿过稳焰齿4上的通孔和开槽螺母3装配,将耐磨陶瓷1与稳焰齿4固定一起。耐磨陶瓷1与稳焰齿4采用燕尾螺栓2和开槽螺母3连接,连接结构简单、稳固,方便安装和拆卸。
以上所述仅为本实用新型的较佳实施例而已,并不用以限制本实用新型,凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本实用新型的保护范围之内。
