Abstract
Description
Technical Field
[0001] The utility model relates to a dust collection device used in the production process of lithium batteries, belonging to the technical field of blanking dust collection equipment. Background Technique
[0002] When producing lithium battery ternary cathode materials, most use automated production lines. Before the materials enter sintering, they need to be blanked into crucible containers. The existing blanking method is as follows: there is a blanking port above and a crucible below, and the materials fall from the blanking port and drop into the crucible. Since there is a certain distance between the blanking port and the crucible, dust is easily generated when the materials fall, resulting in waste of materials and pollution of the production environment. Content of the Utility Model
[0003] Aiming at the deficiencies in the prior art, the utility model proposes a dust collection device used in the production process of lithium batteries. The dust collection device solves the problem of dust by installing an automatically lifting dust-proof device between the blanking port and the crucible, reducing the generation of dust, and avoiding waste of materials and pollution of the production environment.
[0004] The technical solution of the utility model: A dust collection device used in the production process of lithium batteries, including a frame, a blanking pipe, a bellows cover, a dust collection cover, a bracket, a cylinder, and a support plate. A support plate is fixedly installed at the bottom of the frame, a cylinder is fixedly installed on the support plate, a bracket is fixedly connected to the telescopic rod of the cylinder, a dust collection cover is fixedly connected to the upper end of the bracket, a blanking hole is opened in the center of the dust collection cover, and the blanking hole is connected to the blanking pipe through the bellows cover.
[0005] Further, two dust collection holes are opened on the dust collection cover, one end of the dust collection hole is fixedly connected to one end of a dust collection pipe, and the other end of the dust collection pipe is connected to an external dust collector.
[0006] Further, a photoelectric sensor is installed at the bottom of the dust collection cover.
[0007] Further, a sponge is pasted on the inner edge of the blanking hole.
[0008] Due to adopting the above technical solution, the advantages of the utility model are as follows: The utility model adds a foldable and sealed blanking channel between the blanking pipe and the crucible, reducing dust and material sputtering. During the dust collection process, since the dust collection cover and the crucible are filled with sponge, it will not affect the weighing during the blanking process. The invention reduces waste of materials and purifies the production environment. Description of the Drawings

Specific implementation mode
[0013] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.
[0014] Embodiment
[0015] See Figures 1 to 3 , a dust collection device for lithium battery production process of the present utility model includes a frame 1, a blanking pipe 2, a bellows cover 3, a dust collection hood 4, a support 6, a cylinder 7 and a support plate 8. A support plate 8 is fixedly installed at the bottom of the frame 1, a cylinder 7 is fixedly installed on the support plate 8, a support 6 is fixedly connected to the telescopic rod of the cylinder 7, a dust collection hood 4 is fixedly connected to the upper end of the support 6, a blanking hole 11 is opened in the center of the dust collection hood 4, and the blanking hole 11 is connected to the blanking pipe 2 through the bellows cover 3. The bellows cover 3 serves as a foldable sealing channel.
[0016] Two dust collection holes 12 are opened on the dust collection hood 4, one end of the dust collection hole 12 is fixedly connected to the dust collection pipe 9, and the other end of the dust collection pipe 9 is connected to an external dust collector. In this way, a negative pressure can be formed within the range of the dust collection hood 4 to remove dust in a timely manner.
[0017] A photoelectric sensor 10 is installed at the bottom of the dust collection hood 4, and the photoelectric sensor 10, the external dust collector and the cylinder 7 can be uniformly controlled through a controller.
[0018] A sponge 5 is attached to the inner edge of the blanking hole 11, and the sponge 5 can prevent dust from leaking through the gap between the dust collection hood 4 and the sagger.
[0019] Working principle of the present utility model:
[0020] During production, when the sagger containing the material is conveyed to directly below the blanking pipe 2, the controller obtains an induction signal through the photoelectric sensor 10, and then controls the cylinder 7 to act. The cylinder 7 moves downward, and the bracket 6 connected to the telescopic rod of the cylinder 7 drives the dust collection hood 4 to move downward together. After the stroke of the cylinder 7 reaches, the dust collection hood 4 just covers the sagger, and the sponge 5 fills the entire gap between the sagger and the collection hood. At this time, the bellows 3 is stretched, forming a sealed space between the dust collection hood 4 and the blanking pipe 2. At this time, the material starts to be discharged, and the material falls into the sagger through this sealed space. After the discharging is completed, the dust collection pipe 9 installed on the dust collection hood 4 starts negative pressure dust collection. After the dust collection is completed, the cylinder 7 moves upward, and the frame 1 drives the dust collection hood 4 to move upward, and the bellows 3 folds, and the discharging ends.
[0021] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it. For those skilled in the art, the technical solutions recorded in the above embodiments can be improved and modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
