粉碎机用双除尘结构、除尘型双轴粉碎机

Abstract

本实用新型公开了一种粉碎机用双除尘结构、除尘型双轴粉碎机，包括机壳，机壳设置有粉碎腔，粉碎腔的腔壁设置有除尘孔，机壳在设置除尘孔的腔壁外安装有除尘密封板，除尘密封板和设置除尘孔的腔壁外侧形成除尘通道，除尘通道与粉碎腔相通；在除尘通道的两侧对称设置有除尘风机。粉碎腔中的粉尘从除尘孔被抽入到除尘通道，再从除尘通道进入到除尘风机，最后从除尘风机的排出口排出。本实用新型在机壳的粉碎腔加设两个除尘风机同时对粉碎腔进行除尘，将粉碎腔中灰尘尽可能抽出，提高粉碎物料的洁净度。粉碎机使用一个动力同时带动多个结构工作，节省能源，而且使用皮带进行传动，提高传动的缓冲能力，降低故障率。
