Description

一种装修垃圾破碎用破袋机 技术领域
本发明属于装修垃圾再利用领域，特别涉及一种装修垃圾破碎用破袋机。
 背景技术
长期以来，国内装修垃圾废弃物的处理主要是采用堆放、填埋等传统方式，每年约需占用土地20万亩，而回收利用率仅在5%左右，造成 “装修垃圾围城”的局面，这既导致了大量的土地资源被浪费，也对环境造成了污染，在很大程度上阻碍了城市发展，损害了人民健康。面对与日俱增的装修垃圾废弃物，人们的环保意识逐渐提高，政府相关部门制定的规划日益完善、装修垃圾废弃物处置企业也不断兴起。
近年来，国内一些地方对装修垃圾废弃物资源化处理设备有所研发、制造，但总体上生产的装备仍滞后于产业发展需求，关键技术和重要装备尚未有重大突破，基本都是采用矿山机械装备，各工序之间难以有效衔接，而且缺乏成熟的处理工艺。不少企业相对粗放的加工处理方式极易造成再生资源浪费甚至二次污染，并且常常由于设备部件配合不合适，造成垃圾缠绕，筛分不彻底的问题。
 技术问题
为了解决上述现有装修垃圾进行再利用处理时，生产效率和专业化程度不高，同时存在容易发生布条状等条形垃圾的缠绕、筛分不彻底的技术难题，本发明提供了一种装修垃圾破碎用破袋机，技术方案具体为：一种装修垃圾破碎用破袋机，包括两组水平排布相向转动的轴筒，每组轴筒上均单独地设置有间隔排布的啮合齿形结构，两组的啮合齿形结构设置相同，错位排布，两组轴筒的转动轴与变频减速装置传动连接，所述变频减速装置用于轴筒转速调整。

作为改进，端部与根部连接位置设置初始矩形截面W 1与L 1相同。
作为改进，所述啮合齿形结构设置为耐磨材料结构，所述结构设置为主体为16Mn钢或高镍合金，表面涂覆有一层厚度的耐磨层，所述耐磨层的各组分及组分的重量比为：MoSi 2 0.1-3%、Al 2O 345-75%、环氧树脂5-20%、Si 3N 4 0.1-2%、有机硅改性聚丙烯酸酯5-17%、氧化铬8-15%。
作为改进，通过连接的变频减速装置调整两组轴筒转速，其中两轴筒的转动线速度比设定为1：（0.75~0.5）。
作为改进，两组轴筒进行啮合时，两轴筒的相对啮合齿形结构行程为L 标准+20cm，L 标准为两组轴筒相互啮合时的最小轴筒中心直线距离。
作为改进，还包括除污单元，单独地固定安装在两轴筒的底部，设置为间隔多组与啮合齿形结构相匹配的耐磨板组成，耐磨板设置为沿轴筒切线方向，间隙设置为2-7mm。

本发明中啮合齿形结构与常规技术的直型啮合齿型相比，啮合齿形结构在前端设置有有一定角度的齿形结构，易于滑开、撕裂装修垃圾中的条形、条状垃圾，防止发生缠绕；同时，设置有中间按照线性等比例递减的矩形结构，采用齿形结构，易于滑开、撕裂装修垃圾中的条形、条状垃圾的取出。
