Description

Technical Field

[0001] The present disclosure relates to the technical field of lithium battery production equipment, and in particular to a powder material iron removal device and lithium battery production equipment. Background Art

[0002] Lithium battery production equipment is an industrial equipment used to produce lithium batteries. Battery powder is needed in the process of lithium battery production. The battery powder contains some iron foreign matter (i.e. magnetic foreign matter). Before lithium battery production, the battery powder needs to be deironed to remove the magnetic foreign matter in the battery powder. Lithium battery production equipment consists of a conveying device and a powder deironing device. The conveying device is connected to the powder deironing device. The conveying device is used to transport the battery powder to the powder deironing device. The powder deironing device is used to remove the magnetic foreign matter in the battery powder.

[0003] In the prior art, a conventional powder material iron removal device comprises a device body and a telescopic component. The device body is provided with a first connecting through hole, an iron removal chamber and a second connecting through hole which are connected in sequence. The telescopic component is sequentially passed through the first connecting through hole, the iron removal chamber and the second connecting through hole. The telescopic component is movably connected to the device body. The telescopic component is provided with a permanent magnet rod body, which is located in the iron removal chamber and is used to absorb magnetic foreign matter in the powder material, such as the Chinese patent with patent number CN201410562706.7.

[0004] However, since the permanent magnet rod is located in the iron removal chamber to absorb magnetic foreign matter in the powder, after the permanent magnet rod has been used for a period of time, the magnetic foreign matter absorbed on the permanent magnet rod accumulates to a certain extent. At this time, the telescopic assembly drives the permanent magnet rod to move out of the iron removal chamber to facilitate the removal of the magnetic foreign matter on the permanent magnet rod; in the process of the telescopic assembly driving the permanent magnet rod to move out of the iron removal chamber, the main body of the device stops feeding and removing iron, so that the powder iron removal device stops feeding and removing iron, which is not convenient for continuous feeding and removing iron of the powder, and makes the powder iron removal device have poor continuity in feeding and removing iron of the powder.

[0023] Compared with the prior art, the present invention has at least the following advantages:

[0024] 1. Since the feeding assembly is provided with a feeding port for conveying powder into the accommodating chamber, the feeding port is located above the non-magnetic material feeding hopper, and the feeding port is located between the first iron removal magnetic assembly and the second iron removal magnetic assembly. The first iron removal magnetic assembly and the second iron removal magnetic assembly are both used to absorb magnetic foreign matter in the powder, so that the magnetic foreign matter in the powder is absorbed by the first iron removal magnetic assembly and the second iron removal magnetic assembly to form non-magnetic powder, so that the non-magnetic powder enters the non-magnetic material feeding hopper along the accommodating chamber for feeding;

[0025] 2. Since the first sweeping brush member is in contact with the first de-ironing magnetic component, when the first de-ironing magnetic component moves, the first sweeping brush member sweeps the magnetic foreign matter on the first de-ironing magnetic component, and the first de-ironing magnetic component is used to absorb the magnetic foreign matter in the powder to form the first magnetic powder.

Similarly, the second iron removal magnetic component can absorb magnetic foreign matter to form a second magnetic powder during its movement. The second magnetic powder is swept away from the second iron removal magnetic component by the second sweeping brush during the movement of the second iron removal magnetic component, thereby avoiding the second magnetic powder from being adsorbed and accumulated on the second iron removal magnetic component. This cycle is repeated so that the second magnetic powder adsorbed on the second iron removal magnetic component can be better removed.

[0053] The present disclosure also provides a lithium battery production equipment, including the powder iron removal device 10 described in any of the above embodiments. Since the powder iron removal device 10 has good continuity in removing iron from the powder, the powder iron removal device 10 improves the powder processing efficiency and improves the production efficiency of lithium batteries.

[0054] Compared with the prior art, the present invention has at least the following advantages:

[0055] 1. Since the feeding assembly 200 is provided with a discharge port 2221 for conveying powder into the accommodating chamber 110, the discharge port 2221 is located above the non-magnetic material discharge hopper 140, and the discharge port 2221 is located between the first iron removal magnetic assembly 300 and the second iron removal magnetic assembly 400, the first iron removal magnetic assembly 300 and the second iron removal magnetic assembly 400 are both used to absorb magnetic foreign matter in the powder, so that the magnetic foreign matter in the powder is absorbed by the first iron removal magnetic assembly 300 and the second iron removal magnetic assembly 400 to form non-magnetic powder, so that the non-magnetic powder enters the non-magnetic material discharge hopper 140 along the accommodating chamber 110 for discharge;

[0056] 2. Since the first sweeping brush 500 is in contact with the first de-ironing magnetic component 300, when the first de-ironing magnetic component 300 moves, the first sweeping brush 500 sweeps the magnetic foreign matter on the first de-ironing magnetic component 300. The first de-ironing magnetic component 300 is used to absorb the magnetic foreign matter in the powder to form the first magnetic powder. The first magnetic powder falls off from the first de-ironing magnetic component 300 under the sweeping action of the first sweeping brush 500. The abutment between the first sweeping brush 500 and the first de-ironing magnetic component 300 is located above the first magnetic material discharge hopper 130, so that the first magnetic powder falls off and enters the first magnetic material discharge hopper 130 along the accommodating cavity 110 for discharge. Similarly, since the second sweeping brush 600 is in contact with the second de-ironizing magnetic component 400, when the second de-ironizing magnetic component 400 moves, the second sweeping brush 600 sweeps the magnetic foreign matter on the second de-ironizing magnetic component 400, and the second de-ironizing magnetic component 400 is used to absorb the magnetic foreign matter in the powder to form a second magnetic powder. The second magnetic powder falls off from the second de-ironizing magnetic component 400 under the sweeping action of the second sweeping brush 600, and the abutment between the second sweeping brush 600 and the second de-ironizing magnetic component 400 is located above the second magnetic material discharge hopper 150, so that the second magnetic powder falls off and enters the second magnetic material discharge hopper 150 along the accommodating cavity 110 for discharge;

[0057] 3. Since the first de-ironing magnetic component 300 can absorb magnetic foreign matter to form the first magnetic powder during its movement, the first magnetic powder is swept away from the first de-ironing magnetic component 300 by the first sweeping brush 500 during its movement, thereby preventing the first magnetic powder from being adsorbed and accumulated on the first de-ironing magnetic component 300. This cycle is repeated so that the first magnetic powder adsorbed on the first de-ironing magnetic component 300 can be better removed without stopping the machine in the middle, thereby achieving continuous unloading. Similarly, the second de-ironing magnetic component 400 can absorb magnetic foreign matter to form the second magnetic powder during its movement. The second magnetic powder is swept away from the second de-ironing magnetic component 400 by the second sweeping brush 600 during its movement, thereby preventing the second magnetic powder from being adsorbed and accumulated on the second de-ironing magnetic component 400. This cycle is repeated so that the first magnetic powder adsorbed on the second de-ironing magnetic component 400 can be better removed. The second magnetic powder can be better removed without stopping the machine in the middle, and continuous feeding is achieved, thereby solving the problem in the prior art that the telescopic component drives the permanent magnet rod body to move out of the iron removal chamber to remove magnetic foreign matter, and avoiding the problem in the prior art that the device main body needs to stop feeding and iron removal during the process of removing magnetic foreign matter, that is, avoiding the problem of needing to stop the machine during the process of removing magnetic foreign matter; in the process of powder iron removal, the feeding component 200, the first iron removal magnetic component 300, the second iron removal magnetic component 400, the first sweeping brush 500 and the second sweeping brush 600 work together to enable the feeding port 2221 to continuously transport powder into the accommodating chamber 110, so that the powder iron removal device 10 can continuously feed and iron removal, thereby achieving continuous feeding and iron removal of powder, so that there is no need to stop the machine during the process of removing magnetic foreign matter, thereby making the powder iron removal device 10 have better continuity in feeding and iron removal of powder, thereby improving the powder iron removal device 10 The processing efficiency of the powder processing device 10 on the powder.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
