Description

一种双路控制吸脂器及废脂回收装置
本申请要求于2014年05月27日提交中国专利局、申请号为201410227567.2、发明名称为“一种双路控制吸脂器及废脂回收装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及润滑技术领域，特别是涉及一种双路控制吸脂器及废脂回收装置。
背景技术
润滑油脂能够降低传动部件之间的磨擦系数，降低摩擦副的摩擦阻力，减缓磨损。
一些机械设备具有带密封结构的摩擦副，例如轴承，加注润滑油脂后，经过一段时间的运行，润滑油脂会氧化变质，基础油逐渐析出后润滑油脂会变硬，同时，润滑油脂中会有磨损产生的磨屑，这些变质、变硬并带有磨屑的润滑油脂将影响润滑效果。
通常，针对带有密封结构的摩擦副，为了确保良好的润滑，需要定期向摩擦副的内腔加注新的润滑油脂，但是，加注新的润滑油脂时，如果旧的润滑油脂不能及时排出，将会恶化润滑环境，影响润滑油膜的形成，甚至会加剧摩擦副的磨损。常用的解决方式是，加注新的润滑油脂时，利用新的润滑油脂的压力将旧的润滑油脂挤出。但是，由于旧的润滑油脂变质变硬，新的润滑油脂很难使其彻底排出，残留的旧的润滑油脂会影响润滑效果，甚至会使磨损加剧。
因此，如何使得带有密封结构的摩擦副中的旧油脂能够及时排出，保证新油脂顺利注入并形成有效润滑油膜，保证摩擦副的润滑效果，是本领域技术人员目前急需解决的技术问题。
发明内容
本发明的目的是提供一种双路控制吸脂器，该双路控制吸脂器能够使 得带有密封结构的摩擦副中的旧油脂及时排出，保证新油脂顺利注入并形成有效润滑油膜，保证摩擦副的润滑效果。本发明的另一个目的是提供一种具有上述双路控制吸脂器的废脂回收装置。
为了实现上述目的，本发明提供了一种双路控制吸脂器，包括壳体、活塞和柱塞；所述壳体具有相邻并连通的活塞腔和柱塞腔，所述活塞腔位于左侧且其直径大于所述柱塞腔的直径；所述活塞与所述柱塞相连，二者分别与所述活塞腔和所述柱塞腔滑动密封配合；所述活塞腔的两端分别具有油口，所述柱塞腔的侧壁与右端面相距预定距离处设有单向进油的吸油口，所述柱塞腔的右端面具有排油口，所述排油口设有单向出油的单向阀；所述活塞向左移动能够带动所述柱塞开启所述吸油口。
优选地，所述活塞能够在所述活塞腔内往复移动，并具有左极限位和右极限位，所述活塞移动到所述左极限位时，所述柱塞能够开启所述吸油口。
优选地，所述柱塞和所述柱塞腔之间设有密封圈，所述密封圈位于所述吸油口左侧。
优选地，所述活塞腔右端的所述油口位于所述活塞腔的侧壁，所述活塞的右端面的外圈设有台阶；所述活塞腔左端的所述油口位于所述活塞腔的左端面。
优选地，所述活塞腔左右两端的所述油口均位于所述活塞腔的侧壁，所述活塞左右两端的外圈均设有台阶。
优选地，所述排油口连接集废脂箱。
本发明还提供了一种废脂回收装置，包括液压泵和换向阀，还包括至少一个所述的双路控制吸脂器和至少一个集废脂箱，所述双路控制吸脂器的所述吸油口连接摩擦副内腔，所述排油口连接所述集废脂箱；所述液压泵和所述换向阀交替向所述双路控制吸脂器的两个所述油口供油。
本发明提供的双路控制吸脂器，包括壳体、活塞和柱塞；壳体具有相邻并连通的活塞腔和柱塞腔，活塞腔位于左侧且其直径大于柱塞腔的直径；活塞与柱塞相连，二者分别与活塞腔和柱塞腔滑动密封配合；活塞腔的两端分别具有油口，柱塞腔的侧壁与右端面相距预定距离处设有单向进油的吸油口，柱塞腔的右端面具有排油口，排油口设有单向出油的单向阀；活 塞向左移动能够带动柱塞开启所述吸油口。
双路控制吸脂器的活塞腔两端的油口分别交替供油，柱塞腔的吸油口连接摩擦副的密封结构。活塞腔两端的油口交替供油时，活塞可以在活塞腔内往复移动，并带动柱塞在柱塞腔内往复移动。活塞腔右端的油口供油时，活塞带动柱塞向左移动，并能够开启柱塞腔的吸油口，此过程中柱塞腔内的体积增大，压强减小，吸油口能够从摩擦副的密封结构中吸取旧的润滑油脂；然后向活塞腔左端的油口供油，活塞带动柱塞向右移动，柱塞挤压柱塞腔内的润滑油脂，润滑油脂将从柱塞腔的排油口排出。向摩擦副的密封结构加注新的润滑油脂时，交替向活塞腔两端的油口供油，活塞带动柱塞往复运动，柱塞腔能够吸出密封结构内的旧的润滑油脂，保证新的润滑油脂顺利注入并形成有效润滑油膜，保证摩擦副的润滑效果。
另一种优选的实施方式中，活塞能够在活塞腔内往复移动，并具有左极限位和右极限位，活塞移动到左极限位时，柱塞能够开启吸油口。
在活塞到达左极限位之前，吸油口未开启，柱塞腔内是一个封闭的空间，并且体积逐渐增大，压强逐渐减小；当活塞到达左极限位时，吸油口刚好开启，此时柱塞腔内的压强较小，能够吸入摩擦副内旧的润滑油脂；活塞带动柱塞向右移动时，柱塞的侧面先封堵吸油口，此时柱塞挤压润滑油脂，润滑油脂能够从排油口排出。
进一步的，柱塞和柱塞腔之间设有密封圈，密封圈位于吸油口左侧，密封圈能够避免活塞腔内的液压油与柱塞腔内的旧的润滑油脂之间的相互渗入。
具体的，活塞和活塞腔也有多种结构，一种结构是右端的油口位于活塞腔的侧壁，活塞的右端面的外圈设有台阶，左端的油口位于活塞腔的左端面；另一种结构是左右两端的油口均位于活塞腔的侧壁，活塞左右两端的外圈均设有台阶。
本发明还提供了一种废脂回收装置，包括液压泵、换向阀和至少一个所述的双路控制吸脂器和至少一个集废脂箱，双路控制吸脂器的吸油口连接摩擦副内腔，排油口连接集废脂箱；液压泵和换向阀交替向双路控制吸脂器的两个油口供油。
双路控制吸脂器具有上述技术效果，则具有该双路控制吸脂器的废脂 回收装置也具有相应的技术效果。

具体实施方式
本发明的核心是提供一种双路控制吸脂器，该双路控制吸脂器能够使得带有密封结构的摩擦副中的旧油脂及时排出，保证新油脂顺利注入并形成有效润滑油膜，保证摩擦副的润滑效果。本发明的另一个核心是提供一种具有上述双路控制吸脂器的废脂回收装置。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
需要说明的是，本申请文件中用于表示方位的用语“左”和“右”均以附图中所示的双路控制吸脂器的结构为基准，并不构成对结构的限制。
请参考图1和图2，图1为本发明所提供的双路控制吸脂器第一种具 体实施方式的结构示意图，其中活塞位于左极限位；图2为图1所示的双路控制吸脂器的活塞位于右极限位的结构示意图。
在一种具体的实施方式中，本发明提供了一种双路控制吸脂器，包括壳体1、活塞2和柱塞3；壳体1具有相邻并连通的活塞腔12和柱塞腔13，活塞腔12位于左侧且其直径大于柱塞腔13的直径；活塞2与柱塞3相连，二者分别与活塞腔12和柱塞腔13滑动密封配合；活塞腔12的两端分别具有油口121，柱塞腔13的侧壁与右端面相距预定距离处设有单向进油的吸油口131，柱塞腔13的右端面具有排油口132，排油口132设有单向出油的单向阀；活塞2向左移动能够带动柱塞3开启吸油口131。
双路控制吸脂器100运行时，活塞腔12两端的油口121交替供油，使活塞2在活塞腔12内进行往复运动；柱塞腔13的吸油口131连接摩擦副内腔400，排油口132连接集废脂箱300，柱塞3往复运动时，柱塞腔13能够吸取摩擦副内腔400中旧的润滑油脂，并通过排油口132排入集废脂箱300。
向摩擦副内腔400加注新的润滑油脂时，启动该双路控制吸脂器100，向活塞腔12两端的油口121交替供油，活塞2往复运动，并带动柱塞3在柱塞腔13内往复移动。活塞2和柱塞3可以设置能够相互配合的结构连接，例如，一者设置燕尾，另一者设置燕尾槽；活塞2和柱塞3还可以为一体结构。
活塞腔12右端的油口121供油时，活塞2带动柱塞3向左移动，并能够开启柱塞腔13的吸油口131，此过程中柱塞腔12内的体积增大，压强减小，吸油口131能够从摩擦副内腔400中吸取旧的润滑油脂；此过程中，旧的润滑油脂进入柱塞腔13。
活塞2到达活塞腔12的最左端后，右端的油口121停止供油，左端的油口121开始供油，然后活塞2带动柱塞3向右移动，柱塞3挤压柱塞腔12内的润滑油脂，润滑油脂受挤压后，从柱塞腔13的排油口132排出；此过程中，排出进入柱塞腔13的润滑油脂。
柱塞腔13具有单向进油的吸油口131和单向出油的排油口132，活塞2带动柱塞3往复运动过程中，通过吸油口131将摩擦副内腔400中旧的润滑油脂吸入柱塞腔13，再通过排油口132排出。此双路控制吸脂器100 能够吸出摩擦副内腔400内旧的润滑油脂，使旧的润滑油脂及时排出，保证新的润滑油脂的顺利注入，新的润滑油脂能够形成有效的润滑油膜，保证了摩擦副的润滑效果。
具体的，柱塞3的长度等于柱塞腔13的长度，活塞2的长度小于活塞腔12的长度，则活塞2能够在活塞腔12内往复运动，柱塞3在柱塞腔13和活塞腔12之间往复运动。柱塞腔13的吸油口131和排油口132可以设置单向阀，根据双路控制吸脂器100的工作过程，在适当的时候开启相应的单向阀，也可以设置一种在适当的时候能够自动开启的单向阀。
在一种优选的实施方式中，排油口132位于柱塞腔13的右端面，并设有单向阀4，单向阀4的阀腔14位于排油口132右侧的壳体1内；此结构的单向阀4与柱塞腔14和活塞腔13共用壳体1。
单向阀4还包括具有封头411的阀杆41、弹簧42和弹簧座43，弹簧座43与阀腔14的内壁配合，弹簧42套装在阀杆41上，一端抵顶弹簧座43，另一端抵顶封头411，并能够使得封头411封堵排油口132；阀腔14的侧壁具有出油口141，封头411压缩弹簧42移动能够使得排油口132开启并与出油口141连通。
单向阀4未开启时，弹簧42抵顶封头411封堵排油口132。当柱塞3向右移动挤压柱塞腔13内的润滑油脂时，受挤压的润滑油脂将从排油口132挤压封头411时，在润滑油脂的挤压下，封头411能够压缩弹簧42移动开启排油口132，并且，排油口132能够与出油口141连通，柱塞腔13内的润滑油脂将经过排油口132由出油口141排出。
柱塞3到达柱塞腔13的最右端时，基本排空了柱塞腔13内的润滑油脂，封头411不受润滑油脂的挤压，弹簧42抵顶封头411再次封堵排油口132，然后，柱塞3向左移动时，开启吸油口131，柱塞腔13可以继续吸取密封结构400中旧的润滑油脂。
请参考图3和图4，图3为本发明所提供的双路控制吸脂器第二种具体实施方式的结构示意图，其中活塞位于左极限位；图4为本发明所提供的双路控制吸脂器第三种具体实施方式的结构示意图，其中活塞位于右极限位。
弹簧42套装在阀杆41上，阀杆41能够为弹簧42导向，可以在弹簧 座43内设置盲孔或通孔，封头411压缩弹簧42时，阀杆41的端部位于盲孔或通孔中，移动不受弹簧座43的限制。弹簧座43上设置盲孔时，润滑油脂不会泄漏，弹簧座43上设置通孔时，可以在阀杆41与通孔之间设置密封圈，或者在弹簧座43外侧安装阀座44。
一种具体的实施方式是，单向阀4还包括阀座44，阀座44密封阀腔14的右端；弹簧座43具有通孔431；封头411位于阀杆41的左端，阀杆41的右端穿过通孔431。阀座44的可以设置盲孔或通孔，封头411压缩弹簧42移动时，弹簧座43和阀座44都不会限制阀杆41的移动，例如，图3中阀座44设置了通孔，阀杆41较长，在阀杆41和通孔之间设置了密封圈，保持阀腔14端部的密封；图4中阀座44内部设置了盲孔，阀杆41的长度可以较短。
进一步具体的实施方式中，出油口141位于阀腔14的侧壁的左端，阀腔14能够连通排油口132和出油口141。排油口132相当于单向阀4的进油口，封头411开启后，润滑油脂可以直接进入阀腔14，出油口141设置在靠近排油口132的位置，便于排出阀腔14内的润滑油脂。
在上述各具体的实施方式中，活塞2能够在活塞腔12内往复移动，并具有左极限位和右极限位，活塞2移动到左极限位时，柱塞2能够开启吸油口131。
此结构的吸油口131的位置可以不安装单向阀，在活塞2到达左极限位之前，吸油口131未开启，柱塞腔3内是一个封闭的空间，并且体积逐渐增大，压强逐渐减小；当活塞2到达左极限位时，柱塞3刚好开启吸油口131，此时柱塞腔13内的压强较小，吸入润滑油脂；然后，活塞2带动柱塞3向右移动时，柱塞3的侧面先封堵吸油口131，此时柱塞3挤压润滑油脂，润滑油脂均从排油口132离开柱塞腔13。
进一步优选的实施方式中，柱塞3和柱塞腔13之间设有密封圈133，密封圈133位于吸油口131左侧。密封圈133能够将活塞腔12和柱塞腔13隔离，避免活塞腔12内的液压油与柱塞腔13内的润滑油脂之间的相互渗入。具体的，活塞腔12的结构可以有多种形式。
一种结构如图1至3所示，活塞腔12右端的油口121位于活塞腔12的侧壁，活塞2的右端面的外圈设有台阶21；活塞腔12左端的油口121 位于活塞腔12的左端面。活塞2位于右极限位时，右端的油口121供油时，液压油先对活塞2右端的台阶21施加压力，活塞2向左移动后，液压油对活塞2的右端面施加压力。
另一种结构如图4所示，活塞腔12左右两端的油口121均位于活塞腔12的侧壁，活塞2左右两端的外圈均设有台阶21。与上述结构类似，活塞2位于左右两端的极限位置时，通过油口121通入液压油时，油压先作用在活塞2两端的台阶21上。
请参考图5，图5为本发明所提供的废脂回收装置一种具体的实施方式的结构示意图。
除了上述双路控制吸脂器，本发明还提供了一种废脂回收装置，包括液压泵200、换向阀210、至少一个所述的双路控制吸脂器100和至少一个集废脂箱300，双路控制吸脂器100的吸油口131连接摩擦副内腔400，排油口132连接集废脂箱300；液压泵200和换向阀210交替向双路控制吸脂器100的两个油口121供油。
双路控制吸脂器100具有上述技术效果，则具有该双路控制吸脂器100的废脂回收装置也具有相应的技术效果。
以上对本发明所提供的双路控制吸脂器及废脂回收装置进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
