Abstract
The utility model discloses a coating slurry circulating filtering system of lithium ion battery, which comprises a hopper. One guiding pipe is respectively inserted into two sides of the hopper. The two pipes are communicated with a first guiding pipe through a tee joint. The first guiding pipe is communicated with a pneumatic diaphragm pump. The pneumatic diaphragm pump is communicated with a buffer tank through the second guiding pipe and a first filter screen. The buffer tank is communicated with the pneumatic diaphragm pump through a third guiding pipe. The loading pneumatic diaphragm pump is communicated with the inner part of the hopper successively through a fourth guiding pipe, a second filter screen, a fifth guiding pipe and an opening at the central part of the hopper. The coating slurry circulating filtering system of the lithium ion battery has the following advantages: simple structure, automatic circulation without operation, improved product uniformity, reduced defect rate of product, increased yield rate of product and improved straight passing rate of the whole production process.
Description
Technical field
The utility model relates to a kind of filtration system, particularly a kind of coating lithium ion cell slurry circulated filter system that can improve the stock quality of electrodes of lithium-ion batteries production working procedure of coating.
Background technology
Advantages such as lithium ion battery has voltage height, specific energy height, recycles often, memory time is long, not only on portable electric appts, be used widely as 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 more and more higher to the performance requirement of lithium ion battery.In the lithium ion battery manufacturing process, working procedure of coating is an important step.If the slurry of coating in process of production precipitation, particle, condense, or even rotten will directly influence the pole piece quality, and then influence the quality of entire cell, the while has also been caused the waste of various resources such as material and manpower.Just seem particularly important so ensure the quality of coating coating slurry.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of automatic circulation to need not operation, can improve the coating lithium ion cell slurry circulated filter system of the first-pass yield of yield of products and whole production process.
The technical scheme that the utility model adopted is: a kind of coating lithium ion cell slurry circulated filter system, include hopper, the both sides of described hopper are respectively inserted a conduit respectively, described two conduits connect first conduit by a threeway, described first conduit is communicated with pneumatic diaphragm pump, described pneumatic diaphragm pump is by second conduit and cross first screen pack connection surge tank, described surge tank is communicated with the material loading pneumatic diaphragm pump by the 3rd conduit, and described material loading pneumatic diaphragm pump is successively by the 4th conduit, second screen pack, perforate in the middle of the 5th conduit and the hopper is communicated with hopper is interior.
Described conduit, first conduit, second conduit, the 3rd conduit, the 4th conduit and the 5th conduit all adopt the PE conduit.
The two ends of described conduit, first conduit, second conduit, the 3rd conduit, the 4th conduit and the 5th conduit with between corresponding hopper, threeway, pneumatic diaphragm pump, first screen pack, surge tank, material loading pneumatic diaphragm pump, second screen pack and the perforate that links to each other used connection pad all adopt hard teflon gasket.

The specific embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further specify coating lithium ion cell slurry circulated filter system of the present utility model and how to realize.
As shown in Figure 1, coating lithium ion cell slurry circulated filter system of the present utility model, include hopper 1, the both sides of described hopper 1 are respectively inserted a conduit 2 respectively, described two conduits 2 connect first conduit 7 by a threeway (not shown), described first conduit 7 is communicated with pneumatic diaphragm pump 3, described pneumatic diaphragm pump 3 is by second conduit 8 and cross first screen pack, 4 connection surge tanks 5, described surge tank 5 is communicated with material loading pneumatic diaphragm pump 6 by the 3rd conduit 10, and described material loading pneumatic diaphragm pump 6 is successively by the 4th conduit 11, second screen pack 9, perforate 13 in the middle of the 5th conduit 12 and the hopper 1 and 1 interior connection of hopper.
Described conduit 2, first conduit 7, second conduit 8, the 3rd conduit 10, the 4th conduit 11 and the 5th conduit 12 all adopt the PE conduit.Also be respectively arranged with the ball valve (not shown) that is used to control flow on described two conduits 2.
The two ends of described conduit 2, first conduit 7, second conduit 8, the 3rd conduit 10, the 4th conduit 11 and the 5th conduit 12 with between corresponding hopper 1, threeway, pneumatic diaphragm pump 3, first screen pack 4, surge tank 5, material loading pneumatic diaphragm pump 6, second screen pack 9 and the perforate 13 that links to each other used connection pad (not shown) all adopt hard teflon gasket.Described spacer thickness is between 1.5～2.5mm.
Coating lithium ion cell slurry circulated filter system of the present utility model can self-loopa, and slurry is circulation automatically between hopper, pipeline, surge tank, manually only need get final product beginning to install by above-mentioned syndeton.The power of pneumatic diaphragm pump and material loading pneumatic diaphragm pump can realize that the flow that is connected two conduits above the hopper is to control by ball valve separately by the pressure regulator valve of regulating itself, so that regulate hopper both sides level balance.
Operation principle of the present invention: use pneumatic diaphragm pump power is provided, during operation, slurry moves along the diagram direction of arrow, slurry in the hopper is extracted in the surge tank, middle filter through screen pack, this moment, hopper slurry liquid level descended, and the liquid level sensor output signal allows material loading pneumatic diaphragm pump startup, slurry in the surge tank is delivered to hopper, make liquid level constant.So constantly automatically circulation, the both sides slurry that hopper is easy to generate particle constantly is recycled filtration, can filter out the particle that produces in the hopper, and can to keep the slurry in the hopper is fresh all the time, with the uniformity of guaranteeing to apply.
