Description

一种可拆卸的抽滤器件及抽滤装置 技术领域
本发明涉及过滤设备技术领域，尤其是一种可拆卸的抽滤器件及抽滤装置。
背景技术
过滤是在推动力或者其他外力作用下，悬浮液中的液体透过介质，固体颗粒及其他物质被过滤介质截留，从而使固体及其他物质与液体分离的操作。为加快液体透过介质，可采用减压过滤，通常是使液体透出介质的一侧处于负压状态。
常用的抽滤装置包括布氏烧瓶和布氏漏斗，对布氏烧瓶施以负压，使得布氏漏斗上的液体快速滤过，而进入布氏烧瓶中，然后对布氏烧瓶中的液体进行收集。由于布氏烧瓶瓶口较小，其侧壁上连接口更是结构小巧，因此在清洗布氏烧瓶时，该连接口清洗非常不便，尤其是附有那些难清洗物质；对于需抽滤多个样品时，无法确保布氏烧瓶及时清洗干净，因此只能更换另一个布氏烧瓶来过滤其它样品，这样必然造成需要预备更多的布氏烧瓶，成本增大。
发明内容
本发明针对现有技术的不足，提出一种可拆卸的抽滤器件及抽滤装置，方便抽滤，容易清洗和更换使用。
为了实现上述发明目的，本发明提供以下技术方案：一种可拆卸的抽滤器件，所述抽滤器件包括直管状的抽滤管本体，所述抽滤管本体侧面设置抽气管，所述抽滤管本体的上端口用于与漏斗密封连接，所述抽滤管本体的下端口用于 与集液瓶密封连接，所述抽气管用于真空泵与密封连接。
进一步地，所述抽气管与所述抽滤管本体为切向连接、在所述抽滤管本体内有凸出部、在所述抽滤管本体内有向下的凸出部并且/或者所述抽气管内部有倒喇叭状结构。
进一步地，所述漏斗为布氏漏斗。
进一步地，所述漏斗与所述抽滤管本体的上端口之间为硬连接或软连接，包括密封垫、密封套、密封圈。
进一步地，所述集液瓶与所述抽滤管本体的下端口之间为硬连接或软连接，包括密封垫、密封套、密封圈。
进一步地，所述抽滤管本体的下端口和下端口的口径适合于所连接的漏斗和集液瓶的规格，可以为不同规格的尺寸。
进一步地，所述集液瓶包括平底球形瓶、锥形瓶。
进一步地，所述抽滤管与所述集液瓶之间为磨砂口连接。
一种抽滤装置，所述抽滤装置包括如上所述的抽滤器件。
进一步地，所述抽滤装置还包括真空软管，所述真空软管连接在所述真空泵与所述抽气管之间。
与现有技术相比，本发明具有以下优点：采用直管状的抽滤管本体，所述抽滤管本体侧面设置抽气管，所述抽滤管本体的上端口用于与漏斗密封连接，所述抽滤管本体的下端口用于与集液瓶密封连接，所述抽气管用于真空泵与密封连接。使得抽气在抽滤管本体上完成，集液瓶无需设置抽气结构，因此方便清洗集液瓶，且更换方便；抽滤管本体两端通透，方便清洗侧壁上的抽气管。整个抽滤装置组合使用和清洗均很方便，因此为试验操作带来便利。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图示出的结构获得其他的附图。

图2为抽滤管本体的各种结构示意图；
图示标记：
1、漏斗；2、抽滤管本体；21、加强筋；22、抽气管；23、凸出部；24、向下的凸出部；25、倒喇叭状结构；3、集液瓶；31、磨砂口；4、密封圈；5、真空泵；51、真空软管。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明，若本发明实施例中有涉及方向性指示(诸如上、下、左、右、前、后……)，则该方向性指示仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应 当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
如图1和2所示，一种可拆卸的抽滤器件，所述抽滤器件包括直管状的抽滤管本体2，所述抽滤管本体2侧面设置抽气管22，所述抽滤管本体2的上端口用于与漏斗1密封连接，所述抽滤管本体2的下端口用于与集液瓶3密封连接，所述抽气管22用于真空泵5与密封连接。
在抽滤过程中，由抽气管与真空设备连接，而整个抽滤器件不具备收集滤液的功能，使得滤液或其它易起泡物质不会由抽气管离开，避免造成抽气管受到污染。
另外，即使使用中，存在进入抽气管的杂物，由于抽滤器件本身为两端通透的直管状，抽气管在直管的侧壁上，也非常方便清洗抽气管。
所述抽气管22与所述抽滤管本体2为切向连接(图2A)、在所述抽滤管本体2内有凸出部23(图2B)、在所述抽滤管本体内有向下的凸出部24(图2C)并且/或者所述抽气管内部有倒喇叭状结构25(图2D)，这样的设计保证了所述抽滤管本体2壁上的液体不会流入所述抽气管22中。
如图1所示，一种抽滤装置，包括真空泵5、集液瓶3、抽滤管本体2和漏斗1，漏斗1为布氏漏斗，所述抽滤管本体2为直管状，其侧壁上设有与所述真空泵5连通的抽气管22；所述布氏漏斗密封插设于所述抽滤管本体2上端口中，所述集液瓶3与所述抽滤管本体2的下端口密封连接。
抽滤装置的主体结构为由上至下设置的三个部件：漏斗1、抽滤管本体2和集液瓶3组成，布氏漏斗为承装带过滤的物料，可铺设过滤纸或过滤布，根据所需过滤物料的情况进行选择，布氏漏斗下方与抽滤管本体2形成密封连接，抽滤管本体2本身为两端通透的直管，侧壁上连通有抽气管22，抽气管22与真空泵5连接，而抽滤管本体2下端与集液瓶3密封连接，集液瓶3收集由布氏 漏斗过滤后的滤液。由于抽滤管本体2与两端的部件均为密封连接，经抽气管22抽取空气，造成布氏漏斗的过滤层下方至集液瓶3内的空腔形成负压，对布氏漏斗过滤层上方的物料形成负压抽滤。
真空泵5为整个抽滤装置提供负压，使得需要过滤的物料在负压下得到快速过滤。
由于抽滤装置的抽气是直接作用在抽滤管本体2上，集液瓶3收集到的过滤液或其它物料不易对抽气管22造成污染，不涉及到会粘附到抽滤管本体2的抽气管22；另外抽滤管本体2本身为通透的直管结构，对抽气管22的清洗较为方便。
其次，集液瓶3中不设置抽气管22结构，即使是小口大肚的集液结构，也可用毛刷直接刷洗，清洗方便。
抽气管22与抽滤管2侧壁为切向连接，使得抽气操作不正对下落的滤液，减少滤液进入抽气管22；切向设置使得空气在密封腔内带有旋转作用，使得气流带动的滤液离心下落，不易进入抽气管22。
为防止滤液进入抽气管22，将布氏漏斗的下端口设在抽气管22下方，即低于抽气管22的位置，尤其是布氏漏斗下端口为倾斜口，将最低端侧壁正对抽气管22位置。
为提高布氏漏斗1与抽滤管本体2之间的密封性，两者之间设为硬连接或软连接，包括密封垫、密封套、密封圈4，如传统的带孔密封塞。
同理，集液瓶3与抽滤管2之间设为硬连接或软连接，包括密封垫、密封套、密封圈4，增强两者的密封性。也可将这两者之间设为磨砂口31结构，满足一定的气密性即可。
对于抽滤管本体2两端的密封性，可根据使用需要进行选择，如过滤的物 料性质，真空度等等，使用密封圈4或磨砂口31结构。
抽滤管本体2的下端口和下端口的口径适合于所连接的漏斗1和集液瓶3的规格，可以为不同规格的尺寸。
为防止滤液进入抽气管22，将抽气管22的位置尽可能设置在抽滤管本体2的较高位置，如靠近抽滤管本体2的上端。
集液瓶3可采用常规的球形或锥形瓶结构，能耐一定的负压，因此设为带一定厚度的瓶体。
真空泵5与抽气管22之间是采用真空软管51进行连接，能耐受负压而不变形，同时又带有柔性，方便弯折，使用方便。真空软管51可为三层，中间一层为专用多层绝复合材料，上下两层则为软质不锈钢。
为提高抽滤管本体2的强度，在抽滤管本体2的两端口设置加强筋21。
以上所述仅是本发明的优选实施方式，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，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
