Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery dust removal, in particular to a lithium battery dust removal tube. Background Art

[0002] During the processing of lithium batteries, the pole pieces and shells of the battery cells are cut, wound, stacked, and welded. Various dusts are generated during these processes. The dusts will affect the K value of the lithium battery, thereby affecting the quality of the lithium battery. The dusts in some processes are explosive, so it is necessary to equip the dust-generating points with dust hoods, and connect the dust hoods to the industrial dust collectors through pipes so that the dust can be effectively collected by the dust collectors. The existing pipes only have the function of conveying dust. The larger dust particles sucked by the dust hoods enter the dust collectors through the pipes, which can easily cause the filter element to be blocked, affecting the dust removal efficiency. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a lithium battery dust removal tube.

[0004] The technical solution adopted by the utility model is:

[0005] A lithium battery dust removal pipe, comprising an inlet pipe section, a dust collecting pipe section, a dust removal pipe section and an outlet pipe section connected in sequence, the inlet pipe section comprising a horizontal straight pipe section provided with a dust inlet and an elbow for connecting the dust collecting pipe section, the outlet pipe section comprising a horizontal straight pipe section provided with a dust outlet and an elbow for connecting the dust removal pipe section, the dust collecting pipe section is a vertically arranged U-shaped pipe section, a dust collecting device is provided at the bottom of the dust removal pipe section, the dust removal pipe section is a vertically arranged straight pipe section, at least one dust removal assembly is provided thereon; the dust removal assembly comprises an upper flange, a lower flange, a dust removal rod and connecting bolts, the dust removal rod comprises an annular portion for connecting the upper flange and the lower flange and a plurality of dust removal rods arranged at equal intervals in the circular cavity of the annular portion, the upper flange, the dust removal rod and the lower flange are connected in sequence by connecting bolts.

[0006] The dust-laden gas enters from the dust inlet and flows through the inlet pipe section, the dust collecting pipe section, the dust removal pipe section and the outlet pipe section in sequence. The elbows in the inlet pipe section and the dust collecting pipe section cause the gas to change its direction of movement multiple times. During the turning process, coarse dust particles are first separated from the gas; in the dust removal pipe section, the larger and heavier dust particles that collide with the dust removal rod have their kinetic energy reduced and are also separated from the gas; the separated dust falls into the dust collecting device at the lowest point of the dust removal pipe, thereby achieving the removal of large dust particles.

[0007] Furthermore, the dust removal pipe section also includes a spray device arranged above the dust removal assembly. After a period of use, the dust adhering to the pipe wall and the dust removal rod can be cleaned by the spray device.

[0008] Furthermore, the spray device comprises a spray pipe, one end of which extends into the dust removal pipe section and is connected to a spray head. Water is supplied through the spray pipe, and the use of the spray head can improve the cleaning effect.

[0009] Furthermore, the dust collecting device comprises a short pipe connected to the dust collecting pipe section and a dust collecting box, wherein the dust collecting box is threadedly connected to the short pipe and a dust containing cavity is arranged inside the dust collecting box. The threaded connection facilitates cleaning of dust in the dust collecting box.

[0010] Furthermore, the cross section of the dust removal rod is circular or rectangular. The dust removal rod with a circular or rectangular cross section is convenient for processing and cleaning.

[0011] Furthermore, the rectangular dust removal rod and the circular ring portion are integrally formed, which is easy to manufacture and low in cost.

[0012] Furthermore, there are four dust removal components. When viewed from top to bottom, the dust removal rod of the second dust removal component forms an angle of 30° with the dust removal rod of the first dust removal component, the dust removal rod of the third dust removal component forms an angle of 60° with the dust removal rod of the first dust removal component, and the dust removal rod of the fourth dust removal component forms an angle of 90° with the dust removal rod of the first dust removal component.

[0013] Multiple staggered dust removal rods are interwoven into a network in space, which can increase the contact opportunities between dust and the dust removal rods, prevent the escape of large dust particles, and improve the dust removal efficiency.

[0014] Furthermore, each dust removal assembly has 12 corresponding screw holes for installing connecting bolts on the upper flange, lower flange and the annular portion of the dust removal rod. The arc angle of two adjacent screw holes is 30°, which is suitable for the dust removal rod to be staggered by 30°.

[0015] Beneficial effects of the utility model:

[0016] 1. The present application sets a dust removal assembly in the dust removal pipe section, which is beneficial to the collision principle between the dust removal rod and the dust, and can effectively remove dust with larger particles, thereby preventing the clogging of the dust collector filter element, extending the service life of the filter, and reducing the workload of the dust collector.

[0017] 2. The present application can effectively collect the separated dust particles by arranging a dust collecting device at the bottom of the dust collecting pipe section, and can prevent the separated dust particles from being carried away again when the suction force of the suction hood is large.
