Problems solved by technology

[0002] If the current energy storage battery is formed by acid pot, the formation time will be longer and the production efficiency will be low
The current acid cycle system is that the upper part enters and exits the acid. At this time, the concentration of the upper and lower parts of the acid is inconsistent, and there will be a certain concentration difference, and the chemical formation effect is still not ideal.
The best acid circulation method is bottom-in and top-out cycle formation, but there is currently no corresponding battery tank with a bottom opening and a sealing method

Abstract

The invention provides a battery container with a hole in a bottom part. The battery container comprises a container body, a bottom cover plate and a sealing valve and also comprise a sealing ring anda bottom cover, wherein the container body comprises a bottom plate with a hole, a thread is arranged at an inner side of the hole, a groove and a first boss are sequentially arranged on the bottom plate from the hole to outside, the bottom cover plate comprises a connection part and a shunting part, the connection part is in threaded connection with the hole, an internal thread is arranged on the connection part, the sealing valve is provided with an external thread, the external thread is matched with the internal thread, a second boss is arranged at an end part of the sealing valve, the sealing ring is pressed and fixed between the sealing valve and the groove, the bottom cover comprises a third boss and a flange, the third boss props against the first boss, the flange is arranged at an outer side of the first boss, the flange and the second boss are respectively arranged at two sides of the first boss, and the flange and the first boss are molten and welded integratedly by heat sealing. By the battery container, lower-upper acid circulation waterproof formation can be achieved, and the battery container is good in formation effect and reliable in sealing effect.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a battery tank with holes at the bottom and a sealing method thereof. Background technique [0002] If the current energy storage battery is formed by acid pot, the formation time will be longer and the production efficiency will be low. The current acid cycle system is that the acid enters and exits from the upper part. At this time, the concentration of the acid in the upper and lower parts is inconsistent, and there will be a certain concentration difference, and the conversion effect is still not ideal. The best way of acid circulation is bottom-in and top-out cycle formation, but there is currently no corresponding battery tank with a hole in the bottom and a sealing method. Contents of the invention [0003] The invention provides a battery tank with a hole at the bottom and a sealing method thereof, which can realize stable and reliable sealing of the acid c...
