Abstract
The utility model discloses a battery slurry filtering system, which comprises a feeding receiving pipe, a membrane pump and a discharging receiving pipe connected in sequence. A first filter is arranged between the feeding receiving pipe and the membrane pump and is internally provided with a filter net; and an air pressure balancing port is formed in a top wall or a side wall. With the adoption of the structure, battery slurry is only subjected to the force of gravity when passing through the first filter net during discharging so that small grains are avoided from being extruded through the filter net due to larger pressure in a slurry storage container caused by the function of the membrane pump; therefore, the small grains, in particular soft grains, in the slurry can be effectively removed.
Description
Technical field
The utility model relates to a kind of filtration system, cell size filtration system during particularly a kind of lithium ion battery is produced.
Background technology
Lithium ion battery have voltage height, specific energy high, recycle often, advantage such as memory time is long; Not only on portable electric appts; Be used widely like mobile phone, DV and laptop computer; And be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore increasingly high to the performance requirement of lithium ion battery.
Electrode plates is the important component part of lithium ion battery, is important link in the lithium ion battery production process, be the core of lithium ion battery, and the performance of cell size has directly determined the quality of battery pole piece.
Because the restriction of slurrying production technology, there are a large amount of granules that form by conductive electrode and glue in the cell size of finally having made.In order to remove these granules, present powder slurry and working procedure of coating be mounting filtering net on discharge system and feeding system respectively, to reach the effect of filtering particle in the slurry.Because existing discharge system and feeding system adopt membrane pump discharging and material loading, the pressure on the screen pack reaches 0.1～0.2MPa, under this pressure; Granule in the slurry; Especially the soft particle of conductive agent and glue formation is easy to through screen pack, does not reach real filter effect.
The utility model content
The technical problem that the utility model will solve is, particle in a kind of removal cell size is provided, especially soft particulate filtration system.
For solving the problems of the technologies described above; The cell size filtration system that the utility model provides comprises charging adapter, membrane pump and the discharging adapter that connects successively; Wherein, Between described charging adapter and membrane pump, first filter is set, said first filter interior is equipped with screen pack, has the air pressure balance mouth on roof or the sidewall.
Adopt said structure, during discharging, cell size only receives the gravity effect during through first screen pack; Avoid effect because of membrane pump; Make in the slurry storage container that pressure is big and make granule push through screen pack, can go out granule in the slurry effectively, especially soft particle.
As the further improvement of the utility model, above-mentioned cell size filtration system can also be provided with second filter between described membrane pump and discharging adapter, in order further cell size to be filtered, remove wherein impurity and particle.As preferred version, described second filter is two of series connection.
As the improvement on the other hand of the utility model, above-mentioned cell size filtration system can also be between membrane pump and discharging adapter, tramp iron separator being set, so that remove the iron tramp in the cell size better.As preferred version, tramp iron separator can be arranged between second filter and the discharging adapter.
Technical scheme by the utility model provides is visible; Compared with prior art; The cell size filtration system that the utility model provides has overcome that soft particle is easy to can remove the soft particle in the cell size to greatest extent through filtering the technical problem of filter screen in the prior art; Improve the quality of cell size, thereby improved the quality of battery pole piece.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to understand the technical scheme of the utility model better,, the utility model is done to specify further below in conjunction with accompanying drawing.
During work, earlier charging is taken over 1 and link to each other with the pulper discharging opening, discharging is taken over 9 and is starched dolly with fortune and link to each other.Open pulping tank discharging opening valve and compressed air; Slurry takes over 1 through the 2 entering disk filters 6 that are flexible coupling from charging; Have air pressure balance mouth 4 on the sidewall of disk filter 6, inside is provided with screen pack 3, and slurry passes through the screen pack 3 of disk filtration 6 under the gravity effect; Like this, some soft particle major parts are filtered.Slurry after the filtration further filters through twice disk filtration net 7 under membrane pump 5 effects, passes through tramp iron separator 8 deironing at last, and the slurry after the deironing is through the 10 entering fortune slurry dollies that are flexible coupling.This system has removed the impurity in the cell size to greatest extent, has guaranteed the quality of cell size.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
