本实用新型是采用如下方案实现的：一种实验室玻璃反应釜液封装置，包括设置在反应釜封头中心孔内的均竖直开有通孔的外筒体和内筒体以及穿过反应釜封头中心孔的搅拌轴；外筒体的底部开口端水平向内延伸后再竖直向上延伸形成内筒壁；所述外筒体的外筒壁与反应釜封头中心孔孔壁密封固定连接；所述内筒体由上而下嵌入外筒体的内外筒壁之间且内外筒体之间不接触；所述搅拌轴穿过内筒体通孔伸入反应釜内且与内筒体上方开口密封固定连接。 The utility model is realized by adopting the following scheme: a laboratory glass reaction kettle liquid sealing device, which comprises an outer cylinder body and an inner cylinder body with through holes vertically arranged in the central hole of the head of the reaction kettle and through The stirring shaft of the central hole of the head of the reaction kettle; the bottom opening end of the outer cylinder extends horizontally inwards and then extends vertically upwards to form the inner cylinder wall; the outer cylinder wall of the outer cylinder and the central hole wall of the head of the reaction kettle Sealed and fixed connection; the inner cylinder is embedded between the inner and outer cylinder walls of the outer cylinder from top to bottom and there is no contact between the inner and outer cylinders; the stirring shaft extends into the reaction kettle through the through hole of the inner cylinder and is connected with the The upper opening of the inner cylinder body is sealed and fixedly connected.
外筒体与内筒体之间不接触，形成一个缝隙，从此缝隙处注入水，使搅拌轴与反应釜之间形成水封。使用时，将本实用新型搅拌轴与电机相连，开启搅拌后，内筒体随搅拌轴一起转动，这样反应过程中生成的气体则因水封而不会从搅拌轴与反应釜空隙中外泄。 There is no contact between the outer cylinder and the inner cylinder, and a gap is formed, and water is injected into the gap to form a water seal between the stirring shaft and the reaction kettle. When in use, the stirring shaft of the utility model is connected with the motor. After the stirring is started, the inner cylinder rotates together with the stirring shaft, so that the gas generated during the reaction will not leak from the gap between the stirring shaft and the reaction kettle due to the water seal.
本实用新型设计合理可靠，克服了传统机械密封使用寿命短、密封不严的问题，大大减轻了气体外泄给人体造成的危害。具有结构简单、加工方便的优点。 The utility model has a reasonable and reliable design, overcomes the problems of short service life and poor sealing of traditional mechanical seals, and greatly reduces the harm caused by gas leakage to the human body. It has the advantages of simple structure and convenient processing.

具体实施方式 Detailed ways
一种实验室玻璃反应釜液封装置，包括设置在反应釜封头2中心孔内的均竖直开有通孔的外筒体1和内筒体4以及穿过反应釜封头2中心孔的搅拌轴6；外筒体1的底部开口端水平向内延伸后再竖直向上延伸形成内筒壁；所述外筒体1的外筒壁与反应釜封头2中心孔孔壁密封固定连接；所述内筒体4由上而下嵌入外筒体1的内外筒壁之间且内外筒体之间不接触；所述搅拌轴6穿过内筒体4通孔伸入反应釜内且与内筒体4上方开口密封固定连接。 A liquid sealing device for a laboratory glass reactor, comprising an outer cylinder 1 and an inner cylinder 4 which are arranged in the center hole of the reactor head 2 and are vertically opened with through holes and an inner cylinder 4 which passes through the center hole of the reactor head 2. The stirring shaft 6; the bottom open end of the outer cylinder body 1 extends horizontally inwards and then extends vertically upwards to form an inner cylinder wall; the outer cylinder wall of the outer cylinder body 1 is sealed and fixed to the central hole wall of the reaction kettle head 2 connection; the inner cylinder 4 is embedded between the inner and outer cylinder walls of the outer cylinder 1 from top to bottom and there is no contact between the inner and outer cylinders; the stirring shaft 6 extends into the reaction kettle through the through hole of the inner cylinder 4 And it is sealed and fixedly connected with the upper opening of the inner cylinder body 4 .
外筒体1上方外筒壁上开有螺纹，并通过螺母3将外筒体1与反应釜封头2相连接固定。 Threads are provided on the wall of the outer cylinder above the outer cylinder 1, and the outer cylinder 1 and the head 2 of the reaction kettle are connected and fixed by nuts 3.
外筒体1的外筒壁可以采用螺栓的方式与反应釜封头2固定也可以采用焊接的方式实现固定，二者之间采用密封件进行密封。 The outer cylinder wall of the outer cylinder body 1 can be fixed to the reaction kettle head 2 by means of bolts or by welding, and a seal is used for sealing between the two.
内筒体4上方通过紧定螺钉5与搅拌轴6连接，组成一个固定装置。 The upper part of the inner cylinder 4 is connected with the stirring shaft 6 through a set screw 5 to form a fixing device.
由附图可以看出，外筒体1相当于是双层结构，中心呈通孔结构，内筒壁长度一般长于外筒壁；内筒体4由上而下插入外筒体1的内外筒壁之间的间隙，外筒体1的外筒壁上端还可以向内侧延伸一定距离，缩小与内筒体4筒壁的间隙7，以保证水封的效果。水通过外筒体1与内筒体4上部的间隙注入。 It can be seen from the drawings that the outer cylinder 1 is equivalent to a double-layer structure, the center of which is a through-hole structure, and the length of the inner cylinder wall is generally longer than that of the outer cylinder wall; the inner cylinder 4 is inserted into the inner and outer cylinder walls of the outer cylinder 1 from top to bottom Between the gap, the upper end of the outer cylinder wall of the outer cylinder body 1 can also extend a certain distance inwardly, narrowing the gap 7 with the inner cylinder body 4 cylinder walls, to ensure the effect of water sealing. Water is injected through the gap between the outer cylinder body 1 and the upper part of the inner cylinder body 4 .
所述搅拌轴6为不锈钢材质制成，所述内外筒体为聚四氟乙烯材质制成。聚四氟乙烯材质抗酸抗碱、抗各种有机溶剂的特点，几乎不溶于所有的溶剂。同时，聚四氟乙烯具有耐高温的特点，它的摩擦系数极低，还可起到润滑作用。 The stirring shaft 6 is made of stainless steel, and the inner and outer cylinders are made of polytetrafluoroethylene. PTFE is resistant to acid and alkali, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is extremely low, and it can also play a lubricating role.
