TECHNICAL FIELD
[0001] The present application relates to a dust collecting device and a dust collecting bin, belonging to the field of dust collection. BACKGROUND
[0002] At present, with the rapid development of 3C electronics and new energy vehicles, the demand for lithium ion batteries also increases rapidly, and in the production of lithium ion battery positive materials, processes such as mixing, sintering, and crushing of powder materials are involved. Various types of super mixers are used to mix raw materials in the mixing process, and the upper cover of the super mixer needs to be opened to check the uniformity of the mixed materials. After the materials are mixed, a large amount of material dust will be discharged, which will harm the health of the on-site technicians, increase the difficulty of environmental management on site, and cover the equipment parts with dust, affecting the service life of the equipment. How to efficiently and flexibly handle the problem of material dust generated during the "checking uniformity" and "discharging" processes in the process of small-batch research and development and large-scale production line production is particularly important. In the current actual experimental production process, large indoor integrated dust removal equipment is mostly used to solve this problem. However, the mixture of lithium ion battery positive materials (containing lithium carbonate, lithium hydroxide, and lithium cobaltate) has strong suspension ability, and under the action of the super mixer, it generates extremely high dust concentration, which produces local high-concentration dust clusters near the mixing port and discharge port of the super mixer. The existing large indoor integrated dust removal equipment cannot efficiently and flexibly handle the high-concentration dust clusters in this area. Most of the existing small dust collecting devices are built-in dust collecting bins, which are difficult to replace quickly in actual use, and all need electricity as a power source, which has certain safety hazards.

The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.
[0027] Figure 1 A dust collecting device according to a first embodiment of the present application is shown. The housing 2 of the device is a hollow bell-shaped body, and has two holes at the top so that the compressed air interface 1 and the dust discharge interface 6 can enter the inside of the housing 2, and has at least one hole at the bottom so that the dust suction pipe 11 in the dust suction device 4 can be in contact with the outside. In an embodiment not shown, the housing 2 can also be a column, and the holes corresponding to the compressed air interface 1 and the dust discharge interface 6 can be at any position other than the bottom of the housing 2, and the hole corresponding to the dust suction pipe 11 can be at any position other than the top of the housing 2.
[0028] In the embodiment shown in Figure 1, the compressed air interface 1 is fixedly connected to three compressed air inlet pipes 3, and one end of the compressed air inlet pipe 3 is connected to the dust suction device 4; the dust discharge interface 6 is fixedly connected to three dust discharge pipes 5, and the other end of the dust discharge pipe 5 is connected to the dust suction device 4 (not shown); so that a passage is formed, which includes the compressed air interface 1, the compressed air inlet pipe 3, the dust suction device 4, the dust discharge pipe 5 and the dust discharge interface 6 in sequence. In an embodiment not shown, the number of compressed air inlet pipes 3, dust suction devices 4 and dust discharge pipes 5 can be one to many. Figure 1 Figure 1 In the embodiment shown in Figure 1, the compressed air interface 1 is fixedly connected to three compressed air inlet pipes 3, and one end of the compressed air inlet pipe 3 is connected to the dust suction device 4; the dust discharge interface 6 is fixedly connected to three dust discharge pipes 5, and the other end of the dust discharge pipe 5 is connected to the dust suction device 4 (not shown); so that a passage is formed, which includes the compressed air interface 1, the compressed air inlet pipe 3, the dust suction device 4, the dust discharge pipe 5 and the dust discharge interface 6 in sequence. In an embodiment not shown, the number of compressed air inlet pipes 3, dust suction devices 4 and dust discharge pipes 5 can be one to many.
[0029] Figure 2 The internal structure of the dust suction device 4 according to the first embodiment of this utility model is shown. The housing 12 of the dust suction device 4 is a cuboid with a channel running through the middle and penetrating two opposite sides, through which the airflow accelerating capillary 10 is placed. One end of the airflow accelerating capillary 10 is fixedly connected to the compressed air inlet pipe 3, and the other end is fixedly connected to the dust discharge pipe 5. The cross-sectional area of the airflow accelerating capillary 10 is smaller than that of the compressed air inlet pipe 3.

[0030] refer to Figure 1 and Figure 2 In the first embodiment of this utility model, the compressed air interface 1 is connected to a compressed air source, allowing compressed air to enter the compressed air interface 1. Subsequently, the compressed air supplies air to the three dust suction devices 4 via three compressed air inlet pipes. In one dust suction device 4, when the compressed air flows into the gas acceleration tube 10, the reduced cross-sectional area of the channel further accelerates the compressed air flow rate. Then, as it flows through the dust suction pipe 11, a negative pressure difference is generated between the suction port of the dust suction pipe 11 and the outside environment, causing external dust to be drawn into the dust suction pipe 11 and enter the dust discharge pipe 5 along with the compressed air. Finally, the compressed air in the three dust discharge pipes 5 and the external dust converge at the dust discharge interface 6.
