Detailed Description
In order to make the present invention clearer, the present invention will be further described with reference to the accompanying drawings.
In the existing lithium ion battery pulping process, a large amount of small particles often exist in the prepared pulp, a simple screen is generally adopted to directly carry out filtering operation by utilizing natural gravity, a layer of filtering screen is added above a cylinder, the filtering mode is that under the condition that the particles of the pulp are very fine or easily agglomerate, in the filtering process, the particles of the pulp are easy to block meshes of the screen, so that the filtering efficiency is reduced, and meanwhile, the labor is wasted, when a similar structure of a filter core is adopted, the filter screen surrounding the filter core cannot move, a feed port is opposite to one place for a long time for carrying materials, so that the filter screen close to one side of the feed port bears a function of firstly contacting and firstly filtering, and at the moment, large particles in the pulp are firstly filtered and remained on the filter screen, the filter screen in the area is easy to block, the part is closer to the feed inlet, the blocking is equivalent to blocking the feeding, the efficiency is greatly influenced, and the waste of slurry can be caused.
In particular to a lithium battery slurry filtering device with two layers of relatively rotating filter screens, please refer to fig. 1-4; comprises a tank body 1, wherein the lower part of the side wall of the tank body 1 is provided with a feed inlet 11, and an upper cover arranged at the upper end of the tank body 1 is provided with a discharge outlet 12; the tank body 1 comprises a stainless steel cylinder 2, a first filter screen 3 and a second filter screen 4 which are wrapped on the outer side of the cylinder wall of the stainless steel cylinder 2, and the stainless steel cylinder 2 is connected with an upper cover; a plurality of round holes are formed in the wall of the first filter screen 3 and the wall of the stainless steel cylinder 2; a second filter screen 4 is arranged on the outer side of the first filter screen 3, a circular hoop 41 is arranged at the bottom of the second filter screen 4, and the circular hoop 41 is connected with a motor; when the motor works, the circular hoop 41 is driven to rotate, so that the first filter screen and the second filter screen form a relative rotation structure; the second filter screen rotates, the part of the slurry input from the feed inlet, which is contacted with the second filter screen, is changed constantly, so that the precedent that a certain part is blocked due to the fact that the part of the slurry is contacted with the feed inlet in advance for a long time does not exist, because the filter screen close to one side of the feed inlet is contacted with the slurry for a long time and is filtered, the probability of blocking the filter screen of the part is greatly higher than that of other parts, and the second filter screen rotates to not only improve the filtering efficiency, but also prevent partial blocking after long-term use; the second filter screen rotates, and large agglomerates possibly existing in the slurry can be broken up to a certain degree; the rotating speed can be controlled to be 1r/min-5r/min, and the aperture of the round hole on the stainless steel cylinder is 3-5 mm.
In this embodiment, the tank 1 further includes a lower cover 13, the motor is disposed outside the lower cover 13, a rotating shaft 42 of the motor passes through the lower cover 13 and is connected to the circular hoop 41 through a connecting frame 43, and two ends of the connecting frame 43 cross two end points of any diameter connecting line of the circular hoop 41; when the motor works, the circular hoop 41 is driven to rotate, so that the second filter screen rotates; the circular hoop can be tightly attached to the lower cover, and then the connecting frame is used for connecting two end points from the inside of the circular hoop, so that the circular hoop is driven to rotate.
In this embodiment, the first filter screen and the second filter screen are both cylindrical, and the first filter screen and the second filter screen are spaced by 2-3cm, because the filter can be better performed at the spacing distance, and the influence on the efficiency is small.
In this embodiment, the second filter screen 4 is further provided with a scraper 44, and the scraper 44 rotates with the second filter screen 4 and abuts against the first filter screen 3; therefore, the second filter screen can scrape larger particles from the first filter screen when rotating, and the particles are scattered and agglomerated. And, the scraper is close to the one end setting of feed inlet, can raise the efficiency, because the feed inlet is in the bottom, so thick liquids rise slowly then filterable, so the filter screen of bottom has served as more filtration tasks, so set up the scraper in the lower part and just can reach better effect.
In this embodiment, the mesh number of the first filter 3 is smaller than that of the second filter 4, so that the filtering effect can be further improved.
The utility model has the advantages that:
1) the second filter screen can rotate relative to the first filter screen, so that the second filter screen is prevented from being in a filtering state of a unique area for a long time, and blockage is avoided;
2) and be provided with the scraper on the second filter screen, can carry out the granule to first filter screen and strike off, prevent to block up.
