Abstract

本实用新型涉及一种立磨辊胎,是在辊胎的表面上加工出数道凹槽,使之成为带有防滑凹槽的辊胎。本实用新型可以适应无烟煤等硬度较高、摩擦系数低的煤种。同时,由于这种结构增加了研磨时的接触面积,可显著提高出力。

Description

立磨辊胎
技术领域
本实用新型涉及机械设备磨煤机的部件,具体涉及一种立磨辊胎,属于国际专利分类B02C技术领域。
背景技术
粉碎煤炭用的磨煤机大量用于火力发电部门,磨煤机的辊胎需要大量消耗。现有磨煤机的辊胎耐磨性差,加工成型困难,辊胎磨损后不能再修复使用,使用成本高,磨煤效率低。
发明内容
本实用新型的目的,在于克服现有技术中的不足,提供一种提高磨煤时接触面积的立磨辊胎。
本实用新型的技术方案如下:
一种立磨辊胎,是在其辊胎的表面上加工出数道凹槽。
本实用新型的结构设计,使之成为带有防滑凹槽的辊胎,可以适应无烟煤等硬度较高、摩擦系数低的煤种。同时,由于这种结构增加了研磨时的接触面积,可显著提高出力。
附图说明
图1为本实用新型立磨辊胎的侧视结构示意图;
图2为图1的正面结构示意图;
图3为凹槽部分的局部放大示意图。
图中:1、辊胎,2、凹槽。
具体实施方式
参见图1,本实用新型为一种带凹槽的立磨辊胎,是在辊胎1的表面上加工有数道凹槽2;凹槽2的数量可在辊胎表面加工有30-50道。
凹槽2的数量、宽度与深度,可根据煤块的大小作出适当调整,凹槽2数量可在30-50道;凹槽2的宽度可在90-110mm;凹槽2的深度可在100-130mm范围内调整。

Claims (3)

1.一种带凹槽的立磨辊胎,其特征在于:在辊胎(1)的表面上加工有数道凹槽(2)。
2.根据权利要求1所述的立磨辊胎,其特征在于:所述凹槽(2)的数量可为30-50道。
3.根据权利要求1所述的立磨辊胎,其特征在于:所述凹槽(2)的宽度可在90-110mm;深度可在100-130mm范围内调整。
