Benefits of technology

[0028] In this embodiment, a first guide plate is provided in the inner cavity of the slurry tank. The first guide plate has a slurry inlet end, which is close to the feed section and is used to receive the slurry input from the feed section. Therefore, the slurry can flow from the feed section to the slurry inlet end. Since the first guide plate extends from the slurry inlet end toward the bottom of the slurry tank to form a guide path, and the guide path has a first included angle α with the first sidewall, and α is an acute angle, the slurry travels a longer path, has a lower speed, and takes a longer time to flow to the bottom of the slurry tank along the guide path compared to flowing along the first sidewall. Therefore, when the slurry enters the inner cavity of the slurry tank from the feed section and flows to the bottom of the slurry tank along the first guide plate, the air bubbles in the slurry can be fully exposed, which helps to improve the defoaming effect. By setting up a diversion section and a second guide plate, the slurry on the first guide plate can flow to the second guide plate through the diversion section, thereby reducing the thickness of the slurry on the first guide plate, making it easier for air bubbles to be discharged, and improving the defoaming effect of the slurry. Since the second guide plate is connected to the diversion section, and the bottom of both the first and second guide plates are connected to the bottom of the inner cavity of the slurry tank, the slurry is prevented from flowing from the air to the bottom of the inner cavity of the slurry tank, thereby preventing further air bubbles from being trapped during the flow process, improving the defoaming effect of the slurry, and thus improving the quality of the slurry.

Abstract

This utility model provides a battery slurry defoaming device, relating to the field of battery production equipment technology. The device includes a guiding mechanism disposed within the inner cavity of a slurry tank. The guiding mechanism comprises a first guiding plate and a second guiding plate. The first guiding plate extends from the slurry inlet end toward the bottom of the slurry tank to form a guiding path. The guiding path forms a first included angle α with the first sidewall of the slurry tank, where α is an acute angle. A diversion section is provided on the first guiding plate. The second guiding plate is connected to the diversion section, which diverts the slurry on the first guiding plate to the second guiding plate. The bottoms of both the first and second guiding plates are connected to the bottom of the slurry tank. The first guiding plate prolongs the slurry's flow time, which is beneficial for the bursting of air bubbles in the slurry. The diversion section diverts a portion of the slurry from the first guiding plate to the second guiding plate, and then flows to the bottom of the slurry tank, thinning the slurry, promoting bubble bursting, and preventing the incorporation of new air bubbles during the flow process.
