Description
Technical field
Determination of solid content device in a kind of slurry of this utility model design, is specifically related to the solid matter content Accurate Determining device of a kind of pulp of lithium ion battery.
Background technology
Lithium battery electric core slurry agitation is mixing dispersing technology, in the whole production technology of lithium ion battery, the qualitative effects degree of product is more than 30%, is most important link in whole production technology.The preparation of positive and negative electrode slurry all include being mutually mixed between liquid and liquid, liquid and solid material, dissolve, the series of process process such as dispersion, and the most all change along with temperature, viscosity, environment etc..The solid powder content (solid content) of slurry is the key factor affecting slurry viscosity and rheological characteristic, and configuration is stablized the slurry of solid content and is to ensure that the important prerequisite that subsequent handling is smoothed out.
The reasons such as the weighing error that causes due to employee's operating habit when lithium ion battery adds each composition during slurry configures, material loss cause has certain gap between the actual solid content of slurry and theoretical solid content.It is frequently necessary to according to the mobility etc. in slurry viscosity, coating process in actual production, solid content actual to slurry is demarcated to adjust amount of solvent in real time.
Existing weighing equipment, to weigh during temperature and the control of air-flow be unfavorable for high-precision weighing.Dry and automatic weighing structure as Chinese patent (CN 202853711 U) discloses a kind of residue on evaporation, it is provided with platform balance in casing, but utilize fan to be provided with forced circulation air-flow in casing, on the one hand air-flow can make weighting platform vibrations occur, when high-precision weighing, small air-flow all can cause weighing data to have the biggest deviation, on the other hand, air-flow itself is affected by evaporation liquid vapour amount, during rapid evaporation, in casing airflow direction and at a slow speed evaporation time airflow direction there are differences, thus the flow direction of air-flow is the most unstable in causing casing, weighing result is caused to there is bigger random error, it is difficult to be eliminated by statistics and calculating.
And for example Chinese patent (CN 201233354 Y) discloses the meausring apparatus under a kind of vacuum condition, it is provided with extension in casing and claims, the scale pan is lifted on the underface of weight induction device, and heater is arranged on the lower section of the scale pan, thermal updrafts is there is in so causing liquor evaporation processes raising middle flask body, and the scale pan lifted easily rocks under airflow influence, thus cause weighing numerical value and there is deviation.And vacuum pump air inlet pipe when evacuation is positioned at the side of the scale pan, close together, evaporation produces gas, and when causing vacuum to decline, vacuum pump works and also results in the scale pan and rock, and makes weighing precision decline.Additionally, heating element is positioned under the scale pan lower section, need first to heat the scale pan, being conducted heat to slurry by the scale pan, scale pan expanded by heating, for hanging into, scale pan expansion capacity is easily caused the displacement between the scale pan and weight induction device, and this also results in weighing result for high-acruracy survey and deviation occurs.
The most existing equipment is difficult to weigh accurately the monitoring of process.Numerical value before the result of calculation of solid content needs evaporation and after evaporation calculates, and due to meausring apparatus internal temperature and airflow influence, causes the difference claiming the state between body and the scale pan, thus causes result to have the random error that cannot eliminate.
Summary of the invention
The purpose of this utility model is the device providing the control of a kind of air temperature and current to be beneficial to carry out high accuracy slurry determination of solid content.
To achieve these goals, this utility model includes, a casing, and casing is manufactured vacuum environment by vacuum subassembly, and described casing inner bottom surface is provided with platform balance, and heating element heater is positioned at the surface of platform balance.
By heating element is arranged at the surface of platform balance, heating element heater directly heats slurry, is not result in that platform balance local temperature is too high and affects weighing precision.And the thermal current that slurry evaporation produces directly rises, for platform balance, air-flow is little on scale pan impact, and the platform balance scale pan is more stable, and the air-flow making slurry evaporate is small on scale pan impact.So all can guarantee that precisely monitoring weighing process.And before and after evaporation, claiming the change of body state little, the probability that random error occurs is lower.
Preferably, the bleeding point of described vacuum subassembly is positioned on casing inner top surface, and bleeding point airintake direction is horizontally disposed with.
Bleeding point is positioned on casing inner top surface, and be horizontally disposed be avoided that air-flow directly from purgation flow, make air-flow increase at wall box, and reduce air-flow drive the scale pan rising probability, improve certainty of measurement further.
Preferably, described bleeding point has multiple, and bleeding point is close to end face circumference on the inner side of casing and is uniformly distributed.
The equally distributed bleeding point of circumference can make the air-flow in casing more stable, reduces the probability of the vibrations causing platform balance because of air-flow instability.
Preferably, described heating element heater is infrared lamp.Infrared lamp thermal emission directionality is strong, reduces the small vibrations that integrated environment variations in temperature makes each parts differential expansion cause.
Preferably, the scale pan of described platform balance is made up of adiabator.Platform balance local heating is avoided to cause internal structure displacement.
Preferably, described casing has a transparent doors.Transparent it is easy to duty in inspection box body.
Preferably, the control panel of described platform balance is positioned on the outer surface of casing.So can be easy to the operation of platform balance.
Preferably, described vacuum subassembly includes an exhaust tube connected with bleeding point, and this exhaust tube connects with vacuum pump, also includes being positioned at casing vacuum induction installation, and the vacuum display device that is positioned at outside casing and vacuum degree control device, this vacuum degree control device controls the work of vacuum pump.So it is easy to the vacuum being monitored and controlled in casing.
Preferably, in described casing, have temperature inductor, temperature inductor with casing outside temperature indicating device be connected, and temperature control equipment, this temperature control equipment controls the duty of heating element heater.So, it is simple to temperature casing in is monitored and controlled.
