The beneficial effects of the utility model are that thoroughly solved lithium battery pole piece surface adhesion granule problem, improved battery quality greatly, the method relates to a set compact structure simultaneously, can integrate on automation equipment, high efficiency, maintenance are simple.
Description
Technical Field
The utility model belongs to the lithium cell field especially relates to an online dust collector of lithium-ion battery pole piece.
Background
In the subsequent procedures of coating the conventional lithium electrode plate, generated metal particles or coating particles are attached to the surface of the electrode plate, and the particles can cause short-circuit discharge of the battery after the electrode plate is prepared into the battery for charging, thereby influencing the service life of the battery or causing accidents.
Among the chinese patent literature, the publication number is CN202585620U, the utility model discloses a document of "a lithium battery pole piece dust collector" discloses a technical scheme including dust removal pole piece conveyer belt, the piece room is inhaled to the spray-suction dust collector and negative pressure, the spray-suction dust collector sets up the top at the dust removal pole piece conveying, the dust removal mouth of spray-suction dust collector is directly over the dust removal pole piece conveyer belt plane, and there is the clearance that makes the pole piece of waiting to remove dust to pass through between spray-suction dust collector dust removal mouth and the dust removal pole piece conveyer belt, be provided with the ventilation hole on the dust removal pole piece conveyer belt, the piece room setting is inhaled to the negative pressure corresponds the position of spray-suction dust collector below the dust removal pole piece conveyer belt, and the cross section of negative pressure suction piece room is not less than the. The technical scheme has a complex structure, and substances attached to the surface of the pole piece are adsorbed by high-pressure airflow, so that adhered particles are difficult to completely remove, and the cost is high.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an online dust collector of lithium-ion battery pole piece, the purpose provides one kind at the low cost and does not increase the device of getting rid of the granule of extra process, and gets rid of thoroughly.
An online dust removal device for a lithium battery pole piece comprises a dust removal chamber with a symmetrical structure, a left brush roller, a right brush roller, a left dust suction port and a right dust suction port, wherein the left brush roller and the right brush roller are arranged in the dust removal chamber; the dust removal chamber is a sealed cavity, a left dust removal scraper blade and a right dust removal scraper blade are arranged on the side wall of the dust removal chamber, the left dust removal scraper blade and the right dust removal scraper blade are respectively in corresponding contact with the left brush roller and the right brush roller, and the dust removal scraper blade, the brush rollers and the dust collection port form an inner small sealed cavity.
Compared with the prior art, the pole piece coating is fully protected when the particles are removed through the arrangement of the small inner sealing cavity, and the removed particles cannot leak or cause secondary pollution in the sealing cavity of negative pressure.
Based on the above scheme, the utility model discloses following improvement has still been done:
furthermore, the dust removal scraper blade is embedded on the lateral wall of the dust removal chamber through a bolt, and the relative distance between the dust removal scraper blade and the brush roller is adjusted through the bolt.
The beneficial effects of the utility model are that thoroughly solved lithium battery pole piece surface adhesion granule problem, improved battery quality greatly, the method relates to a set compact structure simultaneously, can integrate on automation equipment, high efficiency, maintenance are simple.

in the figure, 1, a dust chamber; 2. sealing the cavity; 3. a dust removal scraper; 4. a left brush roller; 5. a right brush roller; 6. a left dust suction port; 7. a right dust suction port; 8. and (6) pole pieces.
Detailed Description
Examples
As shown in fig. 1 and 2, an online dust removing device for lithium battery pole pieces comprises a dust removing chamber 1 with a symmetrical structure, left and right brush rollers 4 and 5 arranged in the dust removing chamber, left and right dust suction ports 6 and 7 fixedly arranged below the left and right brush rollers and at the bottom of the dust removing chamber, and a battery pole piece 8 moving upwards from the lower part of the dust removing chamber 1; the clean room is seal chamber 2, be equipped with left and right dust removal scraper blade 3 on the lateral wall of clean room, left and right dust removal scraper blade 3 corresponds the contact with left and right brush roller 4, 5 respectively, dust removal scraper blade 3, brush roller 4, 5 and dust absorption mouth 6, 7 constitute inside little sealed chamber. The dust removal scraper blade 3 is embedded on the lateral wall of the dust removal chamber 1 through a bolt, and the relative distance between the dust removal scraper blade and the brush roller is adjusted through the bolt.
The device works in such a way that particles on a pole piece 8 are swept into a small sealed cavity by reversely rolling the left brush roller 4 and the right brush roller 5, the particles attached to the brush rollers are scraped by the dust removal scraper 3, and the air in the small sealed cavity is pumped by the left dust suction port 6 and the right dust suction port 7 to form a negative pressure space so as to convey the particles to the outside of the equipment in real time; when air is pumped, air can only be fed from the upper part, and the particles are thoroughly prevented from overflowing.
Claims (2)
