For viscosity test temperature, and the temperature is also closer to the cell size temperature in tank body 11, in this way, cell size enters survey
Test glass 21 needs not move through the heating of long period when being tested or cooling can be obtained stable and unified test temperature, from
And the testing time can be shortened, and the accuracy and comparativity of guarantee test result further.Preferably, constant temperature keeps adding
The heating temperature of hot device is 25 DEG C ± (0.1 DEG C~0.5 DEG C), at this point, the temperature of cell size equally can be steady in test cup 21
It is scheduled in 25 DEG C ± (0.1 DEG C~0.5 DEG C), i.e., the deviation of test temperature of cell size is no more than 0.1 DEG C, at this point, test result
Most comparativity.
In another embodiment of the invention, constant temperature retainer 26 is constant temperature water bath retainer, i.e., using heating water bath
Mode maintains the constant of temperature, such as thermostat water bath etc.；Alternatively, constant temperature retainer 26 or gas bath constant temperature retainer,
The constant of temperature, such as insulating box etc. are maintained by the way of gas bath heating.
In another embodiment of the invention, as shown in Figure 1, viscosity is calculated as rotational viscometer.Rotational viscometer is common
Viscosity test meter 22, be easily obtained, and test accurate and reliable.
Another embodiment of the present invention additionally provides a kind of making for pulp of lithium ion battery viscosity on-line monitoring adjustment equipment
With method, as depicted in figs. 1 and 2, comprising the following steps:
S10, the cell size of viscosity to be regulated is placed in tank body 11, and cell size is made to be partially flooded with mixing component
12, the default viscosity input controller that will reach needed for cell size starts mixing component 12 to the cell size in tank body 11
It is stirred, cell size carries out conjunction slurry under the stirring of mixing component 12, while with the lasting carry out cell size of stirring
Viscosity change.
S20, the cell size after stirring is delivered in test cup 21 by fluid-conveying pipe, opens viscosity test meter 22
Viscosity test is carried out to the cell size in test cup 21, and obtains the real time viscosity value of cell size.Every a preset duration,
Test cup 21 draws cell size out of tank body 11 by fluid-conveying pipe, so that viscosity test meter 22 carries out viscosity test.
Cell size in test cup 21 is transmitted back in tank body 11 by S30, fluid-conveying pipe, and with the battery in tank body 11
Slurry agitation mixing.
Real time viscosity value is fed back to controller by S40, viscosity test meter 22, and with the default viscosity that is arranged in controller into
Row compares, when real time viscosity value meets the requirements default viscosity requirement, i.e. when the viscosity of cell size meets requirement, and control
Mixing component 12 is closed in device control, conversely, controller controls stirring group when the viscosity of i.e. cell size is unable to satisfy use demand
Part 12 continues to stir.
S50, step S20~S40 is repeated, is preset until viscosity test meter 22 tests obtained real time viscosity value satisfaction
Until viscosity requirement.
It in the present embodiment, in step slo, can also be in controller while by default viscosity input controller
Several different mixing parametrics are set, after executing step S40, if the real time viscosity value detected is unable to satisfy default viscosity and needs
It asks, then controller is controlled mixing component 12 according to real time viscosity value obtained and continued pair with different or identical mixing parametric
Cell size in tank body 11 is stirred, in this way, adjusting stirring group in real time for the different real time viscosity values that test obtains
The mixing parametric of part 12, so as to more quickly meet the requirements the viscosity of cell size.Specifically, mixing parametric is to stir
Mix mixing speed and the mixing time etc. of component.
It should be noted that addition solvent etc. can also be passed through while adjusting the mixing parametric of mixing component 12
Mode adjusts the viscosity of cell size.
The method that the pulp of lithium ion battery of the embodiment of the present invention is monitored on-line and adjusts viscosity first will be wait adjust when closing slurry
The cell size of section viscosity is placed in tank body 11, while being met needed for editor's input cell size in the controller for closing pulp grinder 10
