[0028] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0030] The following describes a kind of air-flow conveying device for lithium battery materials provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] Combined with Figures 1 to 7 As shown, a kind of air-flow conveying device for lithium battery materials provided by the present utility model includes an auxiliary feeding mechanism 100, a feeding mechanism 300 arranged in the auxiliary feeding mechanism 100 and a pipe wall cleaning mechanism 200 arranged in the auxiliary feeding mechanism 100. The auxiliary feeding mechanism 100 is used to supply heat to the feeding mechanism 300 and provide rotational kinetic energy for the pipe wall cleaning mechanism 200. After being energized by air flow, the pipe wall cleaning mechanism 200 will continuously clean the feeding mechanism 300, and after being cleaned, the feeding mechanism 300 can continuously cooperate with the air flow to convey the materials.

[0033] The auxiliary feeding mechanism 100 includes a heat-insulating outer tube 110, two flanges 150 arranged at both ends of the heat-insulating outer tube 110, gaskets 160 arranged in the outer ring grooves of the flanges 150, a heat-insulating sleeve 120 installed in the middle of the inner cavity of the heat-insulating outer tube 110, a coil 130 arranged outside the heat-insulating sleeve 120 and two wires 140 connected to the coil 130 and penetrating to the outside of the heat-insulating outer tube 110;

[0034] The pipe wall cleaning mechanism 200 includes an internal gear ring 210 movably installed inside the flange 150, six columns 220 arranged on the inner wall of the internal gear ring 210, a gasket ring 230 installed between the six columns 220, a stability - enhancing wheel disc 250 arranged outside the gasket ring 230 and inside the internal gear ring 210, a beam rod 270 arranged in the transverse hole inside the stability - enhancing wheel disc 250, and a brush roller 280 arranged outside the beam rod 270;

[0035] The feeding mechanism 300 includes an air - flow feeding pipe 310 arranged outside the brush roller 280.

[0036] When the wire 140 is electrified, the coil 130 will continuously generate heat. Finally, the heat energy radiates through the heat - insulating sleeve 120 into the gap between the heat - insulating outer pipe 110 and the air - flow feeding pipe 310 until the whole air - flow feeding pipe 310 is heated, heating the materials and air flowing through the inner cavity of the paint. Finally, the materials passing through the inner cavity of the air - flow feeding pipe 310 can avoid the problem of moisture absorption;

[0037] As the materials are continuously heat - dried, the efficiency of the rotation speed of the materials inside the air - flow feeding pipe 310 will be better. As the air continuously flows along the gap between the heat - insulating outer pipe 110 and the air - flow feeding pipe 310, the heat energy between the multiple heat - insulating outer pipes 110 and the multiple air - flow feeding pipes 310 after forming the cavity can be made constant, avoiding accidents caused by excessive heating of a local air - flow feeding pipe 310.

[0038] Embodiment 2:

[0039] Combined with Figure 3 and Figure 4 As shown, on the basis of Embodiment 1, the pipe wall cleaning mechanism 200 further includes a limit ring buckle 240 fixedly installed inside the gasket ring 230, and the end of the air - flow feeding pipe 310 is movably installed inside the limit ring buckle 240, a cushion block 260 arranged in the outer wall groove of the stability - enhancing wheel disc 250, and two positioning rods 2601 installed inside the cushion block 260;

[0040] Both ends of the beam rod 270 are installed with T - shaped ends, and the T - shaped ends are adapted to penetrate through the transverse holes on the inner inclined surface of the stability - enhancing wheel disc 250;

[0041] The end of the positioning rod 2601 penetrating into the inside of the stability - enhancing wheel disc 250 is provided with a U - shaped groove, and the U - shaped groove is adapted to be clamped outside the T - shaped end.

[0042] Preferably, the six columns 220 are fixedly installed between the built-in gear ring 210 and the cushion ring 230 by welding, and the stability-enhancing wheel disc 250 is fixed on the outer side of the cushion ring 230. After the built-in gear ring 210 is driven by the impeller 320, the driven cushion ring 230 and the stability-enhancing wheel disc 250 will drive the six evenly distributed beam rods 270 to rotate. Then, the brush rollers 280 arranged outside the beam rods 270 will be pushed to rotate circumferentially along the inner wall of the air flow feeding pipe 310. Finally, the materials passing through the inner cavity of the air flow feeding pipe 310 can prevent caking and accumulation problems. At this time, the inner wall of the air flow feeding pipe 310 can be continuously cleaned by multiple brush rollers 280.

[0043] Embodiment 3:

[0044] Combined with Figures 2 to 4 As shown, in the above embodiment, the feeding mechanism 300 further includes two impellers 320 movably installed at both ends of the air flow feeding pipe 310;

[0045] The inner wall of the air flow feeding pipe 310 is provided with a smooth coating;

[0046] The impeller 320 is composed of an inner shaft sleeve, an outer shaft sleeve and a plurality of blades, and the outer shaft sleeve is movably installed in the groove on the inner wall of the heat insulation outer tube 110.

[0047] Preferably, the air flow feeding pipe 310 is positioned and clamped by two limit ring buckles 240. When the material enters the inside of the air flow feeding pipe 310 and is blown by the air flow, the material can be heated and dried to avoid adhesion to the coating on the inner side of the air flow feeding pipe 310. At the same time, the heat energy between the heat insulation outer tube 110 and the air flow feeding pipe 310 can dry the air flow. After the drying air flow helps the impeller 320 to rotate, the two evenly distributed impellers 320 can apply a stable driving force to the two built-in gear rings 210, so as to ensure that the multiple evenly distributed brush rollers 280 effectively scrape the materials on the inner wall of the air flow feeding pipe 310.

[0048] The working principle and usage process of the present utility model: According to the feeding requirements, a selected number of groups of auxiliary feeding mechanisms 100 are pre-connected by bolts until the complete pipeline formed by the multiple groups of auxiliary feeding mechanisms 100. After the multiple groups of auxiliary feeding mechanisms 100 are connected, the head and tail sections of the multiple air flow feeding pipes 310 arranged in the inner cavities of the multiple heat insulation outer tubes 110 are interconnected, and finally a closed feeding cavity is formed;

[0049] When the air flow is input from one end of the air flow feeding pipe 310, the lithium battery material will be pushed by the air flow and transferred along the channel formed by multiple air flow feeding pipes 310. During the transfer, the energized coil 130 will heat the gap between the heat insulation outer pipe 110 and the air flow feeding pipe 310. After part of the air flow flows along the gap between the heat insulation outer pipe 110 and the air flow feeding pipe 310, the two impellers 320 movably installed at both ends of the air flow feeding pipe 310 will rotate at a constant speed after being pushed by the air flow. The ring teeth arranged on the outer side of the impeller 320 will drive the ring teeth on the inner side of the built-in gear ring 210. Finally, the upright post 220 and the gasket ring 230 installed on the inner side of the built-in gear ring 210 will rotate;

[0050] At the same time, the stability increasing disc 250 arranged on the inner side of the gasket ring 230 will drive the six evenly distributed beam rods 270 and six brush rollers 280 in cooperation with the six groups of positioning rods 2601. Finally, the multiple brush rollers 280 will scrape the material passing through the inner cavity of the air flow feeding pipe 310 in a circular motion until the air flow feeding pipe 310 can still maintain a clean state after conveying the material. At the same time, in cooperation with the continuous radiation of heat energy received by the air flow feeding pipe 310 as a whole, the material can avoid being affected by moisture and sticking to the inner wall of the air flow feeding pipe 310 during the conveying process.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and purposes of the present invention.
