The embodiment provides a rapid oxygen exhaust glove box, which can realize rapid oxygen exhaust by using a vacuum pump, so that the oxygen content reaches a usable standard; meanwhile, by using a plurality of electromagnetic valves, the efficiency is greatly improved in the processes of oxygen discharge and inflation; in addition, ingenious at lieing in a pipeline of opening department intercommunication, through electromagnetic valve's the effective balanced gloves inside and outside atmospheric pressure difference of opening and shutting control, prevent gloves fracture or appear and the fracture scheduling problem of being connected of opening, specifically as follows:
the glove box body 1 is a substantially cubic structure, one end of the glove box body 1 is provided with a feeding pneumatic gate 2, the other end of the glove box body is provided with a discharging pneumatic gate 3, a cavity 101 is formed in the glove box body, the bottom of the cavity 101 is provided with a roller shaft 4 arranged side by side, the side wall of the glove box body 1 is provided with at least one opening 14, a glove 15 is arranged in the opening 14, in the implementation, a compression-molded neodymium iron boron permanent magnet needs to be in a vacuum state through film coating before entering the glove box body, the glove 15 is used for film tearing and other operations after entering the glove box body by manual mode, and in order to ensure that the neodymium iron boron permanent magnet is not oxidized, therefore, the adopted glove box body needs to be in an oxygen-free or low-oxygen state all the time, the scheme is characterized in that a vacuum pump 5 is arranged on the glove box body 1, the inside of the chamber 101 is quickly pumped into a vacuum state by the vacuum pump 5 and inert gas is introduced at the same time to prevent the neodymium iron boron permanent magnet from being oxidized, and the biggest difference from the prior art is that the glove box body only has one air inlet for filling the inert gas and an air outlet for exhausting the air inside while filling the inert gas, which causes the problem that in the actual production process, the oxygen exhaust process is slow, the box body is poor in self-tightness and further air supplement is needed. The vacuum pump 5 is ingeniously used and communicated into the cavity 101 through the pipeline I7, so that the problem can be solved, the using effect of the vacuum pump 5 is that oxygen in the cavity 101 is extracted, meanwhile, the flowing direction of the inert gas can be further ensured to be converged at the pipe orifice of the pipeline I7, and the effective filling effect of the inert gas is improved.
In another embodiment, the second pipeline 16 and the second electromagnetic valve 8 on the second pipeline 16 are provided, specifically, the second pipeline 16 may be a branch type pipeline, that is, a plurality of pipelines may be merged and then merged into one pipeline, and a second electromagnetic valve 8 is further installed on the merged main pipeline, and the second pipeline 16 may also be an independent pipeline, and each pipeline 16 is respectively installed with a second electromagnetic valve 8, which is not limited in this embodiment. The second pipe 16 is adaptively communicated with the one opening 14, that is, one port of the second pipe 16 is communicated with the glove 15 inside the opening 14, and the other end is communicated with the chamber 101, it is important to point out that the second pipe 16 is used for keeping the difference between the internal pressure and the external pressure of the glove 15 balanced, that is, the pressure at the opening 14 and the pressure in the chamber 101 balanced, so that the problems of the glove 15 breaking or the glove 15 tearing at the connection with the opening 14 caused by the unbalance of the internal pressure and the external pressure can be effectively prevented.
Further, the glove type medical device further comprises a sealing cover 10, wherein the sealing cover 10 is adapted to be connected with the opening portion 14 so as to drive a semi-closed space with an adjustable sealing state to be formed between the opening portion 14 and the glove 15, the sealing state of the semi-closed space is adjusted through the second electromagnetic valve 8, and it is important to point out that the semi-closed space is a non-closed state in which the opening portion 14 is communicated with the chamber 101 when the second electromagnetic valve 8 is in an open state, and when the second electromagnetic valve 8 is in a closed state, the sealing cover 10 seals and seals the opening portion 14, and at this time, the chamber 101 is not communicated with the opening portion 14 through the second pipeline 16. Thus, when the sealing cap 10 closes the opening 14 and the second solenoid valve 8 is in the open state, the vacuum pump 5 is used to pump vacuum, so that the difference between the inside pressure and the outside pressure of the glove 15 is balanced, and the gas in the chamber 101 is prevented from leaking.
The working principle and the flow of the rapid oxygen discharging glove box will be described in detail by taking an example of the rapid oxygen discharging glove box as follows:
when the neodymium iron boron permanent magnet piece which is formed by pressing and provided with the protective film enters the glove box body 1, firstly, the feeding pneumatic gate 2 is opened, the neodymium iron boron permanent magnet piece is conveyed into the cavity 101 through the roller shaft 4, then, the feeding pneumatic gate 2 is closed, and the discharging pneumatic gate 3 and the sealing cover 10 at the moment are both in a closed state, namely, the cavity 101 is closed. The vacuum pump 5 is started, the first battery valve 6 and the second electromagnetic valve 8 are opened after 5S starting, the chamber 101 is vacuumized through the first pipeline 7, a vacuum pressure gauge 11 is further installed on the glove box body 1 during vacuumizing, the vacuum pressure gauge 11 detects the pressure in the chamber 101, when the set value is 5Pa, the third electromagnetic valve 17 is opened, inert gas (generally, nitrogen gas) is filled into the chamber 101 through the air inlet pipe 12 at the moment, and the first electromagnetic valve 6 is closed after 30 seconds. When the pressure in the glove box body 1 rises to the atmospheric pressure (101Kpa), the exhaust electromagnetic valve 13 is opened to start exhaust, an oxygen content detector 9 is also arranged on the glove box body 1, and when the value of the oxygen content detector 9 reaches a set value (generally, the oxygen content is less than 10ppm), the electromagnetic valve 17, the exhaust electromagnetic valve 13 and the second electromagnetic valve 8 are automatically closed. At this point, the operator may open the sealing cap 10 and work is performed in the chamber 101 through the glove 15. When the oxygen content in the chamber 101 slowly rises and exceeds a set value (for example, 10ppm) during operation, the third electromagnetic valve 17 and the exhaust electromagnetic valve 13 are automatically opened, thereby reducing the oxygen content in the chamber 101. After the operation is finished, the pneumatic discharging gate 3 can be opened.
Further, in order to facilitate the observation of the inside of the glove box body 1 by an operator and to increase the lighting inside the glove box body, the side wall and the top of the glove box body 1 may be partially or entirely made of a transparent material, such as tempered glass, on the premise that the used transparent material may ensure the stability of the overall structure of the glove box body.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
