Description
Technical field
The utility model relates to lithium ion battery preparing technical field, particularly relates to a kind of vacuum pumping device of pulping tank.
Background technique
Lithium ion battery has the advantages such as voltage is high, specific energy is high, recycle often, memory time is long, not only on a portable electronic device as mobile phone, DV and laptop computer are used widely, and be widely used in the big-and-middle-sized electrical equipment aspects such as electric vehicle, electric bicycle and electric tool, therefore more and more higher to the performance requirement of lithium ion battery.Electrode plates is the important component part of lithium ion battery, is the core of lithium ion battery, and producing battery pole piece needs starch through powder, applies, rolls and the operation such as shearing, and wherein powder slurry is the critical process of production battery pole piece, is also first operation.
The process preparing slurry is by powder, glue and NMP add in pulping tank, pass through low rate mixing, rapid stirring dispersion mixes, in slurry working process, pulping tank inside needs to ensure certain vacuum simultaneously, but in whipping process, have air produce, this just needs vacuum pump frequent starting to extract most inner air by pipeline outside connection pulping tank, make the force value reaching an acceptable technological requirement in tank, the quality of such guarantee slurry, but when vacuum pump starts because valve manipulation is asynchronous, be easy to cause air to return and enter pulping tank, cause slurry abnormal, in postorder coating process, pole piece has bubble, the phenomenon of the cosmetic defects such as white point.
Model utility content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of vacuum pumping device of pulping tank.
The technological scheme adopted for realizing the purpose of this utility model is:
A kind of vacuum pumping device of pulping tank, comprise PLC, vacuum-pumping tube with the outside pipeline communication of described pulping tank, be communicated with vacuum pump after being connected in series electric control valve and one-way valve successively at described vacuum-pumping tube, described vacuum pump and electric control valve respectively with described PLC control connection to realize synchronization motion.
In the middle part of described vacuum-pumping tube, form downward recessed section of giving prominence to enter vacuum pump to prevent the liquid in pulping tank.
Described recessed section is also provided with the escape pipe vertically arranged, described escape pipe is provided with escape cock.
Described electric control valve is ecp valve.
Compared with prior art, the beneficial effects of the utility model are:
Vacuum-pumping tube is installed the one-way cock that a kind of allows medium one-way flow, can automatically open during such extracting air, can automatically close when air is taken out most, effectively prevent air to pour in down a chimney, outside pulping tank, pipeline is installed ecp valve simultaneously, come to PLC signal by the start button of vacuum pump, then through PLC transmission of signal, just can ensure that the start and stop of vacuum pump are consistent with pneumatic valve, period there will not be interruption and time delay, and pass through operating in a key, simplify electrical device structures, implement succinct, not only ensure that the quality of slurry can also increase the physical life of vacuum pump.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the vacuum pumping device of pulping tank of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the vacuum pumping device of pulping tank of the present utility model comprises PLC, with the vacuum-pumping tube 2 of the outside pipeline communication of described pulping tank 1, described vacuum-pumping tube 2 is communicated with vacuum pump 5 after being connected in series ecp valve 3 and one-way valve 4 successively, described vacuum pump and ecp valve respectively with described PLC control connection to realize synchronization motion, further, for realizing intelligent control, described pulping tank is also provided with vacuum measuring instrument, described vacuum measuring instrument is connected with described PLC communication, the automatic startup of vacuum pump is controlled by PLC, the intellectuality of raising equipment.
Vacuum-pumping tube is installed the one-way cock that a kind of allows medium one-way flow, can automatically open during such extracting air, can automatically close when air is taken out most, effectively prevent air to pour in down a chimney, outside pulping tank, pipeline is installed ecp valve simultaneously, come to PLC signal by the start button of vacuum pump, then through PLC transmission of signal (PLC inherently has 24V electricity so do not need to connect power supply to electricity) to the relay signal of pneumatic valve, coil obtain electric after, its normally opened contact is closed, pneumatic valve obtains electric laggard action and does.So just can ensure that the start and stop of vacuum pump are consistent with pneumatic valve, period there will not be interruption and time delay, can thoroughly extract air in pulping tank and ensure pulping tank internal pressure all the time at required numerical value, thus the quality ensureing to extract air in pulping tank also ensures the quality of slurry, and pass through operating in a key, simplify electrical device structures, implement succinct, not only ensure that the quality of slurry can also increase the physical life of vacuum pump.Therefore a kind of novel vacuum pumping device solves
Further, vacuum pump is entered for preventing the liquid in pulping tank, outstanding recessed section is formed downwards in the middle part of described vacuum-pumping tube, namely, vacuum-pumping tube is overall in being horizontally disposed with, or at least, vacuum pump and vacuum-pumping tube and pulping tank connecting end are with high or higher than pulping tank connecting end, then one section recessed section is arranged at middle part, can effectively to the liquid buffer memory be entrained with, avoid entering vacuum pump, simultaneously, for ease of discharging liquid, described recessed section is also provided with the escape pipe 6 vertically arranged, described escape pipe is provided with escape cock, while guarantee vacuum tightness, discharge approach is provided to the liquid carried secretly wherein.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
