Description

一种钕铁硼废件废固的预处理装置及使用方法 技术领域
本发明涉及钕铁硼废料加工技术领域,特别涉及到一种钕铁硼废件废固的预处理装置及使用方法。
背景技术
钕铁硼废料是目前稀土永磁废料的主要一类,钕铁硼废料一般有粉状、粒状、块状、泥状、有的含水量多,有的含水量较少,有的浸泡在液体中,有的样品呈现不用的颜色和气味,大多数样品可挥发组分含量较低。钕铁硼废料的回收比矿石直接破碎得到稀土资源更加方便,因为在钕铁硼废料中稀土含量远高于矿石含量。
这也就需要对钕铁硼废料进行回收处理在加工,而在钕铁硼废料的回收主要通过焙烧、酸溶、过滤和萃取等多个步骤,但是,为了保证回收处理工序的处理效果,通常在处理工序之前对废料进行清洁,减少边角料表面带有的油污胶水等,但是现有的清洗装置不能进行很好的清洗效果,现有的将废料放进清洗装置后进行普通的搅拌从而进行清洗然后取出清洗桶,通过这种清洗无法对废料进行很好的清洗清洗过后的杂质还是会在废料的表面无法很好的去除,而采用分离筛选进行清洗,虽然能将清洗后的杂质与废料进行分离,但是在清洗时也只是自动的杂质与废料的分离,不能保证分离效果,并且采用大规模的同时清洗只能进行粗略清洗,钕铁硼废料表面还是会粘附部分杂质,容易在回收过程中降低回收稀土的含量。

具体的,如图2所示,出料装置20还包括:支撑杆202、伸缩电机201,支撑杆202设置在机体10的下方,支撑杆202的一端与第一转动杆203的另一端连接及第二转动杆205的另一端连接,支撑杆202与第一转动杆203、第二转动杆205构成Y形;伸缩电机201设置在支撑杆202的一侧,伸缩电机201的伸缩端与第一转动杆203的中间段连接,伸缩电机201设置有两个,另一个伸缩电机201的伸缩端与第二转动杆205的中间段连接。
具体的,如图3、4、5所示,搅拌装置30包括:驱动电机301、旋转轴302、第一旋转叶303、第二旋转叶304、推动块305,驱动电机301设置在机体10的上方;旋转轴302设置在机体10的内部,旋转轴302穿过机体10的上表面进入机体10的内部,旋转轴302穿入机体10内部的一端插入分隔板109的内部,旋转轴302通过驱动电机301控制旋转;第一旋转叶303设置在旋转轴302的外周,第一旋转叶303与旋转轴302固定连接;第二旋转叶304设置在旋转轴302的外周,第二旋转叶304与旋转轴302固定连接;推动块305设置在第二旋转叶304的外侧,推动块305与第二旋转叶304固定连接。
具体的,第一旋转叶303设置有两组,两组第一旋转叶303之间设置有间距;第二旋转叶304设置有两组,两组第二旋转叶304设置在两组第一旋转叶303之间,第一旋转叶303与第二旋转叶304之间设置有间距。通过搅拌装置30实现对不同分层的废件废固分开清洗,从而使得旋转轴302在清洗过程中无需大批量的对废件废固同时清洗,降低了清洗阻力,减少旋转轴302损坏的情况。
具体的,如图3、4所示,分层装置40包括:分层板401、闭合盘402,分层板401设置 在机体10的内部,分层板401位于分隔板109的上方,分层板401的外周与机体10的内壁贴合连接;闭合盘402设置在分层板401的中间,闭合盘402与分层板401活动连接,闭合盘402与分层板401呈同一圆心设置。闭合盘402的外周设置有齿板,闭合盘402与密封杆108配合连接,密封杆108的外周设置有齿轮,闭合盘402与密封杆108相啮合,闭合盘402通过密封杆108转动利用圆环与分层板401的圆形通孔贴合实现封闭开合。通过分层装置40在钕铁硼废件废固倒入内壳107后,利用密封杆108驱动闭合盘402旋转将闭合盘402与分层板401实现打开从而使得处于分层板401最上层的废件废固顺着分层板401的通孔向下流动,在经过第二个分层板401的时候部分废件废固停留在表面,另外部分接着向下流动流经第三个分层板401,到达第三个分层板401的废件废固接着向下流动最后到达分隔板109表面,当所有分层板401都具有废件废固后,闭合盘402与分层板401重新闭合将一开始大量的废件废固重新分离规划,降低同一空间中废件废固的占有量提高了后续清洗效果,使得废件废固能充分与清洗液混合减少未清洗到的情况出现。因为现有通常对钕铁硼废件废固清洗采用直接导入桶内然后进行搅拌这种方式,在桶内废件废固过多时搅拌轴承受巨大的废件废固阻力无法快速对废件废固进行搅拌清洗,而且过多的废件废固堆积在同一空间中也会造成搅拌轴无法对所有废件废固都搅拌到会存在同一位置的废件废固反复搅拌都处于不改变的情况这就造成了部分废件废固没有清洗的情况降低了清洗效率可能需要重新清洗,通过分层装置40对废件废固进行分层提高清洗效率,降低搅拌轴与废件废固之间的阻力加快搅拌效率。
具体的,分层板401表面设置有圆形通孔,分层板401的中间设置有间距用于容纳闭合盘402;闭合盘402通过圆环组成,闭合盘402的内圈与分层板401中间设置的连接圆环相贴合;分层板401和闭合盘402设置有三个,每一个分层板401和每一个闭合盘402形成一组分层装置40,分层板401和闭合盘402设置有三组彼此之间设置有间距。

具体的,机壳501的中间设置有凹槽,推动板504的一端穿过机壳501的凹槽表面,推动板504的另一端与存气囊505的另一端贴合设置;推动板504用于挤压存气囊505将内部气流推入气流通道506中;喷气装置50设置有两组,喷气装置50每四个为一组,喷气装置50之间设置有间距。密封球507的表面设置有弹性条,弹性条的一端与气流通道506连接,弹性条用于密封球507在被存气囊505的空气顶开后实现复位。
通气孔101与换气孔502相配合,存气囊505、气流通道506、换气孔502、通气孔101形成完整通道。形成的完整通道用于在密封球507对喷气口508进行封闭后存气囊505中的空气能通过换气孔502和通气孔101导流外部的空气进行填充,进而使得存气囊能反复使用。
推动板504穿过机壳501的凹槽表面的一端与推动块305配合连接,推动块305设置成主体为正方形块,在正方形的相对两边设置三角形,推动块305的三角形边与推动板504的一端贴合,推动块305的表面设置有横向设置的长方形条,推动块305的长方形条与推动板504的弧形凹槽相配合,推动板504通过第二旋转叶304转动时带动推动块305挤压存气囊505;喷气装置50与分层装置40成交错设置。通过将推动块305设置为主体呈正方形块,在正方形块的上下两边设置三角形,推动块305通过三角形边与推动板504贴合进行带动推动板504移动,推动板504移动的过程中存气囊505就会将内部的空气挤压入气流通道506实现废件废固混合液中的气泡,而在推动块305移动推动板504的同时,在推动板504移动到机壳501的边界时为了防止推动板504将推动块305卡死导致旋转轴302无法转动,不能对内壳107中的废件废固搅拌的问题,在机壳501的表面设置有滑块,滑块与推动块305相配合,在推动块305转动的路径上推动块305会与滑块配合利用滑块与推动块305产生的摩擦 力使得推动块305旋转,在推动块305旋转的时候推动块305的三角形会与推动板504分离,当推动块305旋转90度时推动块305对推动板504的挤压力就会消失,从而推动板504通过机壳501内置的复位装置重新回到原来位置,而在推动板504回到原来位置的同时存气囊505内部会重新充满空气,在推动块305转动90度后推动块305会通过内置卡簧复位,等下一次转动重新使用。利用第二旋转叶304的转动使得推动块305与推动板504实现重复配合进而使得存气囊505重复喷气吸气,在内壳107中实现气泡的重复喷出,提高废件废固的清洗效果。

进一步的,本发明实施例还公开了:搅拌混合后还包括以下步骤:喷气混合,在旋转轴302转动的同时第二旋转叶304外侧的推动块305会与推动板504接触,在推动块305与推动板504接触后第二旋转叶304的旋转力会使得推动块305顶压推动板504移动,在推动板504沿喷气装置50的机壳501弧形移动时,存气囊505受力向气流通道506输送空气,而流动的空气会挤压在换气孔502内的密封垫509,密封垫509塞住换气孔502的出口,气流通道506内的剩余空气向喷气口508流动,将喷气口508内部的密封球507顶开,从而将空气喷入内壳107中对废件废固和清洗液进行搅动,在经过推动板504挤压存气囊505后,推动块305与机壳501表面设置的滑块配合使得推动块305旋转从而失去对推动板504的推动力, 然后通过内置的复位装置将推动板504复位,在推动板504复位时密封球507回到原来位置重新堵住喷气口508。
进一步的,本发明实施例还公开了:第一卸料板204和第二卸料板206通过伸缩电机201实现打开或闭合,在打开时,伸缩电机201的伸缩端回收,与伸缩端连接的第一转动杆203和第二转动杆205向下转动将第一卸料板204和第二卸料板206向两侧分别倾斜形成倒V形,废件废固从第一卸料板204和第二卸料板206倾斜侧落出。
