Detailed Description

Present graphite precursor body crushing production line is including throwing feed bin 1, feed spiral 2 and rubbing crusher 3, the discharge gate intercommunication feed spiral 2's of throwing feed bin 1 material loading mouth, rubbing crusher 3 is equipped with smashes inlet pipe 31 and smashes discharging pipe 32, smash the one end that inlet pipe 31 kept away from rubbing crusher 3 and seted up air supplement mouth 311, feed spiral 2's feed discharging pipe 21 communicates to smashing inlet pipe 31 middle part, it communicates to cyclone 4's feed inlet to smash discharging pipe 32, it is general, cyclone 4's air outlet still has connected gradually dust remover 5 and draught fan 6 through the pipeline, there are other exceptional circumstances too, nevertheless all do not influence implementation of following scheme

As shown in fig. 2, the feeding bin dust-raising prevention system of the graphite precursor pulverizing production line of the present invention further comprises a dust-proof pipe 11, wherein a dust-proof hole is formed at the upper part of the feeding bin 1, and further, as shown in fig. 2, the dust-proof hole is preferably formed at the upper end of the side surface of the feeding bin 1; one end of the dustproof pipe 11 is communicated with the feeding bin 1 through a dustproof hole, one side of the crushing feeding pipe 31 is provided with a dust suction hole, and the other end of the dustproof pipe 11 is communicated with the crushing feeding pipe 31 through the dust suction hole.

In a preferred embodiment, a dust suction opening is located between the connection of the feed discharge pipe 21 and the comminution feed pipe 31 to the crusher 3.

In order to further avoid the dust from being raised during feeding, optionally, an end cover is further arranged at the upper end of the feeding bin 1, a feeding port 12 is arranged on the end cover, and the size of the feeding port 12 is smaller than that of the end cover.

Referring to fig. 3, due to the existence of the air supply opening 311, wind force in the crushing feed pipe 31 is originally linearly transmitted, the discharging of the feed screw 2 is naturally dropped into the crushing feed pipe 31 and then is linearly sucked into the crusher 3, if the dustproof pipe 11 is perpendicular to the crushing feed pipe 31, negative pressure in the feeding bin 1 is small, and the dust-raising prevention effect is not good enough, so that in another embodiment, the included angle between the dustproof pipe 11 and the crushing feed pipe 31 is smaller than 90 degrees, the more preferable included angle between the dustproof pipe 11 and the crushing feed pipe 31 can be 10-30 degrees, the connection between the dustproof pipe 11 and the crushing feed pipe 31 faces the crusher 3, the inclined arrangement mode is favorable for transmitting negative pressure, and the specific transformation can adopt an inclined tee joint or a customized pipe fitting for integral replacement.

Because the feed inlet of the cyclone separator 4 is under negative pressure (which is a known cyclone separation process requirement and is generally provided by the induced draft fan 6 on the production line), the crushing feed pipe 31 is under negative pressure, and therefore the interior of the dustproof pipe 11 is under negative pressure, so that the interior of the feeding bin 1 is under negative pressure, when feeding is performed under any one of the above embodiments, once dust in the material and in the feeding bin 1 is raised, the dust is sucked into the dustproof pipe 11 under negative pressure and enters the production line pipeline, thereby greatly reducing the raised dust caused by feeding, and being beneficial to improvement of the working environment.

The above are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.

The parts of the present invention not described in detail are known to those skilled in the art.
