Detection unit is stated to be arranged in baking oven and connect with the alarm unit being arranged in outside baking oven；
When foil band by the coater head complete coating after by the baking oven when, detection unit detect oven interior
The concentration of NMP, when concentration is greater than preset value, alarm unit alarm.
The features of the present invention also characterized in that
Air outlet is provided on the baking oven.
The detection unit is gas detector, and the gas detector is arranged at air outlet.
The coater head is direct injection coater head.
The alarm unit is tri coloured lantern.
The method for early warning of NMP concentration over-standard in lithium titanate battery coating process, using above-mentioned lithium titanate battery coating process
The prior-warning device of middle NMP concentration over-standard, is specifically implemented according to the following steps:
Step 1, foil band is coated by coater head；
Step 2, the foil band after being coated by baking oven to the step 1 toasts, while detection unit is real-time
Detect the concentration of oven interior NMP；
Step 3, when the concentration of the NMP of the step 2 detection is greater than secure threshold, alarm unit alarm.
The features of the present invention also characterized in that
The walking speed of coater head is less than or equal to 25m/min in the step 1.
The concentration of oven interior NMP is detected in the step 2 method particularly includes: by exhausting motor by gas in baking oven
It is evacuated at air outlet, the concentration of NMP is detected by the way that the gas detector at air outlet is arranged in.
The range of the concentration secure threshold of NMP in the step 3 are as follows: 14%-16%.
The exhausting motor power is 7.5-10kw, frequency 50HZ.
Compared with prior art, in use, passing through the concentration of NMP in detection unit real-time detection baking oven, when concentration is greater than
When secure threshold, alarm unit alarm avoids the problem of influencing pole piece caking property because of NMP concentration over-standard.
Detailed description of the invention
Fig. 1 is that the embodiment of the present invention provides the structure of the prior-warning device of NMP concentration over-standard in lithium titanate battery coating process
Schematic diagram；
Fig. 2 be the embodiment of the present invention provide lithium titanate battery coating process in NMP concentration over-standard prior-warning device in baking oven
Structural schematic diagram.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention provides the prior-warning device of NMP concentration over-standard in lithium titanate battery coating process, such as Fig. 1-2 institute
Show comprising for the coater head 1 of coating sizing-agent, baking oven 2, detection unit 3 and alarm unit 4 on foil band, coating
Head 1 and baking oven 2 are arranged in same level, detection unit 3 be arranged in baking oven 2 and with the alarm list that is arranged in outside baking oven 2
Member 4 connects, and coater head 1 is direct injection coater head；In this way, when foil band by coater head 1 complete coating after through baking
When case 2, detection unit 3 detects the concentration of 2 inside NMP of baking oven, and when concentration is greater than secure threshold, alarm unit 4 is alarmed.
It is provided with air outlet on baking oven 2, in this way, taking the NMP inside baking oven 2 in time away by air outlet, avoids baking
NMP excessive concentration influences the caking property of coating pole piece inside case.
