Background technology
In the production process of cylindrical lithium ion battery, many links can use compressed air and be used as cylinder, diaphragm
The power source of the equipment such as pump, pneumatic operated valve, equipment surface dedusting etc., if the dew point of compressed air is excessively high will to substantially reduce equipment
Service life can also have a certain impact to the humiture management and control in workshop.For nitrogen, in homogenate, coating, baking, volume
Nitrogen is useful for around processes such as, fluid injections, and nitrogen can be in direct contact with slurry, pole piece, core etc..If the dew point mistake of nitrogen
Height will just directly influence the performance of column lithium ion battery, and for battery, excessively high moisture is extremely serious.
At present, on nitrogen making machine dew point alarm monitor is not installed on air compressor machine and, duration will appear compressed air
Middle moisture is excessively high, and a large amount of moisture is stockpiled in filter or buffer tank, greatly reduces the equipment such as solenoid valve, cylinder
Service life.For nitrogen, dew point influence not up to standard will be more serious, can directly influence column lithium ion battery
Performance even results in battery and scraps, and safety accident etc. occurs.
Utility model content
The purpose of this utility model is to provide a kind of compressed air and nitrogen dew point monitoring and alarming system, when compressed air and
When nitrogen dew point is more than the alarming value of setting, alarm function can be played, Field Force is enable quickly to make a response, reduction pair
The influence of equipment reduces the performance influence on cylindrical battery.
Technical solution is used by the utility model solves its technical problem：A kind of compressed air and the monitoring of nitrogen dew point
Alarm system, including power supply, double loop digital indicator, compressed air dew point transmitter, nitrogen dew point transmitter, intermediate relay
Device I, intermediate relay II, the power supply are electrically connected with double loop digital indicator, the double loop digital indicator and button
One end connection of switch I, key switch II, the other end connection intermediate relay I of the key switch I, the key switch
II the other end connection intermediate relay II, the intermediate relay I, intermediate relay II the other end be electrically connected with power supply
It connects, I one end of normally opened contact connection double loop digital indicator on the intermediate relay I, other end connection alarm device I,
II one end of normally opened contact connection double loop digital indicator on the intermediate relay II, other end connection alarm device II,
Access power supply after the alarm device I, alarm device II are in parallel；The compressed air dew point transmitter, nitrogen dew point pick-up
Device is electrically connected with double loop digital indicator.
Further, the key switch I, key switch II are connected in parallel, the intermediate relay I, intermediate relay
II is connected in parallel.
Further, the alarm device I, alarm device II include 6 audible and visible alarm lamps and 1 flashing buzzer, 6
It is to be connected in parallel between a audible and visible alarm lamp and between flashing buzzer.
The beneficial effects of the utility model are：The device has filled up the blank that compressed air and nitrogen are monitored without dew point, rises
It has arrived when compressed air and exceeded nitrogen dew point, the function of energy sound-light alarm, while personnel can have been made to react rapidly, reduced
Because compressed air and the nitrogen dew point exceeded equipment life brought reduce, the risk that battery performance reduces reduces cylindrical electricity
The cost risk in pond improves the service life of equipment and the reliability of battery performance.
