Description

Technical Field

[0002] In the actual battery production process, its raw materials need to be transported by conveyors to facilitate subsequent mixing and other work. Battery raw materials need to be mixed with additives and other materials. The pneumatic conveying system uses the energy and pressure difference of the airflow to transport granular materials or powders in a closed pipe. This method is efficient, dust-proof and environmentally friendly, has strong adaptability, and high safety. It is particularly suitable for long-distance pipeline transportation of heat-sensitive and flammable materials such as lithium iron phosphate. However, the current pneumatic conveying device for mixing lithium battery raw materials is mainly used for powder raw material transportation, which is not convenient for long-distance transportation of materials with moisture after mixing additives. Raw materials with moisture mostly require manual transportation or long-distance transportation by auger. The cleanliness of the raw materials is not good, and it is not convenient to agglomerate and granulate the raw materials with moisture. The vacuum suction is not smooth enough, and it is also not convenient to clean the pipeline in real time. The traditional method that relies on pneumatic conveying is also prone to residual materials on the inner wall of the pipeline. The discharge barrel of the traditional vacuum conveyor is also prone to adhesion of materials, which is not convenient for adaptive anti-sticking materials and gap compensation. If the residual materials are not cleaned for a long time, it will affect the quality of the battery. Summary of the invention

[0041] The working principle of this embodiment is as follows: first, the support ring 103 is placed on the ground, and the vacuum suction shell 501 is installed in the battery raw material mixing and conveying production line. The battery raw materials mixed with additives are put into the agglomeration hopper 101. At this time, the agglomeration motor 102 drives the extrusion auger 202 to rotate, and squeezes the raw materials downward into the forming cover 302.

After a single discharge is completed, the lower electromagnet 402 can be controlled to be powered off. At this time, under the action of negative pressure, the cleaning ball 403 can be driven to slide in the conveying pipe 301 and scrape the inner wall of the conveying pipe 301. At this time, as the cleaning ball 403 moves to the top of the inclined control cylinder 303, it can be discharged through the upper The electromagnet 5021 magnetically attracts the cleaning ball 403. When the suction net 502 needs to be back-blown, the pressure tank connected to the back-blowing nozzle 503 is turned on to exhaust. At this time, the upper electromagnet 5021 is controlled to be powered off. At this time, under the action of negative pressure, the air pressure of the back-blowing nozzle 503 will blow the magnetic cleaning ball 403 to move in the opposite direction, and then scrape the conveying pipe 301 again and reset to the supporting claw 4011, and then magnetically attract and position it again through the lower electromagnet 402; the material can be discharged by driving the material auger 605 to rotate through the discharge motor 604, and the closed electric push rod 701 is used to push the closing plug 702 to separate from the vacuum suction shell 501, so as to discharge the raw materials. Under the pull of the tension spring 603, the lifting column can be driven 602 is pressed down to make the discharge auger 605 fit the vacuum suction shell 501. The pressure-adjusting threaded ring 608 can be used to adjust the pulling force of the tension spring 603, which can be adjusted according to needs. When the rotating piece 609 is driven upward by rotating the pressure-adjusting threaded ring 608, the length of the tension spring 603 is shortened, and its pulling force is naturally reduced, which can be pre-adjusted according to needs; the cleaning electromagnet 607 can be used for the magnetic discharge mounting frame 601, thereby driving the discharge auger 605 to move upward, and the elastic pulling lifting column 602 of the tension spring 603 is controlled to cut off the power of the cleaning electromagnet 607, so that the discharge auger 605 can collide with the vacuum suction shell 501, thereby achieving vibration cleaning of the discharge auger 605.
