Description

Dust cleaning device in casket-like bowl

Technical Field

The utility model belongs to the technical field of lithium battery production equipment, and particularly relates to a dust cleaning device in a casket.

Background

With the continuous development of the lithium battery industry, the ternary material gradually becomes the key point of the production of the lithium battery anode material. The single crystal ternary material can improve the lithium ion transfer efficiency and reduce the side reaction between the anode material and the electrolyte, thereby improving the cycle performance of the anode material under high voltage and having stable power. The single crystal type ternary material is transported on a conveying line by the saggar, but the single crystal type ternary material belongs to powder, so that the single crystal type ternary material is inconvenient to clean and not clean in the saggar, and a large amount of powder can be accumulated on the subsequent firing and conveying line.

The existing cleaning device is cleaned in a brush form, so that a plurality of defects exist: 1) the brush is adopted, so that some places cannot be cleaned in the cleaning process; 2) dust cannot be intensively treated in the cleaning process; 3) the brush is abraded for a long time in the cleaning process, and the phenomenon of falling off is likely to occur; 4) the cleaning efficiency is low.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems that powder in a saggar is inconvenient to clean and cannot be cleaned cleanly in the prior art, the utility model provides a device for cleaning dust in the saggar.

In order to solve the technical problems, the technical scheme adopted by the utility model is that the device for cleaning dust in the saggar comprises a rack and a plurality of air knives, wherein a dust removal pipe is arranged on the rack, a dust suction port of the dust removal pipe is positioned right above the saggar, the air knives are rotatably arranged at the bottom end of the rack, the air knives are uniformly distributed around the opening of the saggar and are arranged towards the saggar, the rack is driven by a first driving mechanism to move downwards close to or upwards away from the saggar, when the rack moves close to the saggar, the air knives are positioned at the periphery of the saggar, and when the rack moves away from the saggar, an air blowing port of the air knives is driven by a second driving mechanism to move from the outside of the saggar to the inside of the saggar.

Preferably, the air knives are arranged in four rows, the number of the air knives in each row is at least one, the section of the sagger is square, and the four rows of the air knives are arranged corresponding to four corners of the sagger. The four rows of air knives blow up the dust in the saggar and concentrate the dust in the middle of the saggar, and the dust is sucked into the dust removal pipe through the dust suction port, so that the dust is prevented from scattering, and the good dust removal effect can be realized by the four air knives, so that the use cost of the air knives is reduced.

Preferably, the first driving mechanism is a pneumatic mechanism or an electric mechanism, the second driving mechanism is also a pneumatic mechanism or an electric mechanism, and the second driving mechanism drives the air knife to swing.

Preferably, the dust suction port has a flared shape facing the sagger. The dust collection effect of the dust removal pipe is improved.

Further, the rotating angle of the air knife in the saggar is alpha, and the value range of the alpha is 0-360 degrees.

Further, the value range of the alpha is 0-90 degrees. The rotating stroke of the air knife is short, and the dust blowing effect of the air knife can still be ensured.

Has the advantages that:

1) according to the sagger dust cleaning device, the air knife is adopted, the position of the air knife air blowing opening can be moved within a certain range, and compared with the existing brush, the sagger dust cleaning device is cleaner and simpler in cleaning operation;

2) the dust cleaning device in the sagger has better dust suction effect at the dust suction port, and dust suction is more concentrated than the dust suction effect in the prior environment with dust around;

3) the sagger dust cleaning device is simple and reliable in structure and low in manufacturing and using cost;

4) the sagger dust cleaning device does not need to be cleaned frequently, only needs simple wiping and cleaning, and is simple in subsequent maintenance.
