Description

Technical Field

[0001] The utility model relates to a liquid adding device, in particular to a liquid adding device with an anti-overflow function. Background Art

[0002] In a certain production process of lithium batteries, liquid asphalt and graphite powder need to be transported to a mixing tank for mixing. The liquid asphalt in the mixing tank is usually fed by a transport trolley carrying a sub-filling tank and moved to the side of each mixing tank in turn. The discharge pipe on the sub-filling mixing tank is directly connected to the feed port on the corresponding mixing tank by a robotic arm. This causes the liquid asphalt to easily overflow from the mixing tank during the liquid asphalt transportation process, resulting in a waste of resources and a safety hazard. In addition, in the process of feeding the liquid asphalt into the mixing tank, due to the very high viscosity of the liquid asphalt, the liquid asphalt is very easy to adhere to the wall of the mixing tank. The liquid asphalt after adhering to the wall has a larger contact area and a thinner asphalt layer. Therefore, the liquid asphalt will quickly solidify after adhering to the wall, which will affect the mixing of the liquid asphalt and graphite powder in the mixing tank, thereby affecting the quality of the finished lithium battery. In addition, the dried asphalt after adhering to the wall makes it difficult to clean the mixing tank, thereby increasing maintenance costs. Utility Model Content

A first pneumatic butterfly valve 18 is provided between the second flange 16 and the third flange 17, and the bottom end and the top end of the butterfly valve in the first pneumatic butterfly valve 18 are respectively in a fixed communication state with the second flange 16 and the third flange 17.

[0036] A liquid inlet is provided at the top of the transfer storage bin 5, to which a reducing bell tube 19 is fixedly connected.

[0038] Operation process: The transport trolley moves the filling tank containing liquid asphalt to the side of the mixing tank 2, and controls the driving mechanical arm 1 to make the mechanical arm 1 drive the liquid adding pipe 4 to rotate. During this process, the visual camera 7 is used to determine the specific positions of the mixing tank 2 and the liquid through pipe 6, so that the liquid adding pipe 4 is inserted into the liquid through pipe 6. After insertion, the liquid adding operation can be carried out. At this time, it can be determined whether there is liquid asphalt overflow according to the height change of the height control block 9 on the top of the transfer storage bin 5, because there is a position error when the liquid adding pipe 4 is docked. The liquid asphalt does not enter the mixing tank 2; a hose is provided on the sub-filling tank, which is connected to the liquid adding transfer connecting pipe 15, so the liquid asphalt in the sub-filling tank will enter the liquid adding transfer connecting pipe 15 through the hose, and then enter the liquid through pipe 6 through the liquid adding pipe 4. Since the liquid through pipe 6 is connected to the transfer storage bin 5, the liquid asphalt will enter the transfer storage bin 5 at this time. During this process, the pulse valve 8 is controlled to continuously provide pulse airflow to the transfer storage bin 5 to prevent the liquid asphalt from sticking to the inner wall surface of the transfer storage bin 5.
