Description

Technical Field

[0001] The present invention relates to the field of conductive slurry production, and in particular to a multi-stage filtering device and method based on conductive slurry production. Background Art

[0002] Carbon nanotube conductive paste and graphene conductive paste are widely used in lithium battery production because their conductivity is better than traditional conductive agents such as SP and Ketjen Black, and are mainly used as positive electrode conductive agents. However, iron catalysts must be introduced into carbon nanotubes and graphene during the production and preparation process, and metal impurities such as iron must be removed in the later process to reduce the content of metal impurities to a certain range, otherwise it is easy to cause large self-discharge of lithium batteries.

[0004] In the above scheme, the raw pulp is pushed by the discharge rack so that the raw pulp is evenly filtered on the filter net. However, during the filtering process, the filter net will be clogged as the use time increases. In the actual production process, it is necessary to pause the equipment to clean the filter net and then start the filtration, otherwise it will affect the filtering effect. In addition, the cleaning of the existing filter net requires manual disassembly of the equipment, which seriously affects the work efficiency.

[0031] In specific implementation, when there is a large amount of filtration on the top of the filter plate 503, it is necessary to clear the filtrate. In this solution, a complete flow pipeline is formed by combining the upper frame 501, the connecting member 5 and the four side sealing plates 605 arranged therebetween.

The push frame 804 penetrates the sliding plate 801 and is fixedly connected to the bottom of the ejection plate 803, and the push frame 804 is slidably connected to the sliding plate 801; The fifth gear 806 is arranged at the bottom end of the reciprocating screw 805 and is fixedly connected to the reciprocating screw 805 through a one-way bearing. The outer side of the fifth gear 806 is meshed with a partial inner gear ring 807, and the partial inner gear ring 807 is fixedly connected to the bottom of the mounting plate 8.

[0041] When the sliding plate 801 rotates with the lower connecting plate 402, the reciprocating screw rod 805 is driven to mesh with the part of the inner gear ring 807 through the fifth gear 806, thereby driving the reciprocating screw rod 805 to rotate, thereby pushing the pushing frame 804 to rise and pushing the ejection plate 803 to move. When the cleaning is completed, the lower connecting plate 402 rotates and the sliding plate 801 continues to rotate together. In this process, the ejection plate 803 begins to descend. The reciprocating screw rod 805 adopts a reciprocating screw rod, so the ejection plate 803 can be lifted and lowered reciprocatingly, so that when the reciprocating screw rod 805 moves to one end of the arc groove on the sliding plate 801, the magnetic plate 802 is separated from the magnet at the bottom of the lower connecting plate 402 and the ejection plate 803 is also completely removed from the lower frame 502. At this time, the magnetic plate 802 is pushed to reset by the compressed second spring 808, and the next filter plate 503 is cleaned. By cooperating with the cleaning member for cleaning, the overall cleaning effect is improved.

[0042] Embodiment 4: The rotating rod 2 passes through the mounting plate 8 and is rotatably connected to the mounting plate 8. A cleaning frame 902 is attached to the top of the filter plate 9. The cleaning frame 902 is fixedly connected to the rotating rod 2. A discharge pipe 903 is fixedly connected to the middle of the filter plate 9. The discharge pipe 903 extends to the bottom of the upper shell 101. An electric control valve 904 is arranged on the outside of the discharge pipe 903.

[0043] In specific implementation, the material is filtered through the filter plate 503 and falls on the filter disc 9 for filtering. During the switching process of the connecting piece 5, the rotating rod 2 drives the cleaning frame 902 to rotate, scrapes the top of the filter disc 9 to avoid clogging of the filtered material. When cleaning is required later, the electric control valve 904 is opened, and the filtered material falls into the discharge pipe 903 through the filter disc 9 to be discharged.

[0044] A multi-stage filtration method based on the production of conductive slurry is also provided, comprising the following steps: Step 1: The raw material is discharged through the delivery pipe 301, passes through one of the connecting pieces 5, and falls onto the filter disc 9, and then is filtered through the filter disc 9; Step 2: During the filtering process, the upper connecting plate 401 and the lower connecting plate 402 are driven to rotate by the rotating rod 2, so that the other connecting member 5 is switched to the bottom of the conveying pipe 301 for filtering; Step 3: During the switching process of the connecting piece 5, the force storage piece stores force. When the connecting piece 5 is switched, the force storage piece releases the stored force, driving the traction piece to pull the cleaning piece to clean the filter plate 503 inside the switched connecting piece 5.
