Background
Lead-acid storage batteries are classified into industrial, automotive and power types, and when the batteries are used in the process of using the batteries due to the fact that the gas exhausted by the lead-acid storage batteries contains hydrogen, acid mist and other impurities, flame can enter the batteries along the exhaust ports of the batteries to cause explosion of the batteries.
The existing lead-acid battery is generally divided into 2V, 6V and 12V series, a plurality of single grids are arranged in the 6V and 12V battery, each single grid is provided with an exhaust port for exhausting internal waste gas, the waste gas is collected and exhausted in an air guide groove in a surface piece groove, and because the surface piece is sealed by adopting point bonding, only the bonding effect is achieved, no sealing effect exists between the surface piece and a battery cover, the waste gas is exhausted from gaps of the surface piece, and thus if open fire is met, flame is easier to be introduced into the battery along the exhaust port and the gaps of the surface piece, and explosion is generated.
Disclosure of Invention
Aiming at the defects existing in the prior art, the utility model provides an explosion-proof lead-acid storage battery, which has the following specific technical scheme:
the explosion-proof lead-acid battery, battery case to and establish the dough sheet at battery case top, the gas vent has been seted up to the one end in the dough sheet, the top that is located a plurality of cavitys in the battery case all is equipped with the relief valve, the gas outlet that is located the relief valve in the battery case is equipped with the air guide groove that link up with it along the direction of gas vent.
The sealing between the surface piece and the battery shell is changed into a circle of glue groove type from a point type, so that the bonding line of the surface piece and the battery shell is completely sealed, the exhaust port is changed into a centralized type from an emission type, the exhaust gas is intensively discharged from the exhaust port, and the open fire can be prevented from entering from a gap between the surface piece and the battery shell to cause explosion.
As an improvement of the technical scheme, the joint of the surface piece and the battery shell is sealed by glue, so that the tightness between the surface piece and the battery shell is improved, and gaps are prevented.
As the improvement of the technical scheme, the bottom in the exhaust port is also fixedly provided with an air filter, and the air filter is made of PP material.
Through placing the gas filter below the exhaust port, the material is PP, makes it can filter out the acid mist, and concentrate exhaust gas and discharge, and the gas filter also is a barrier and can block open flame and enter into the inside of the battery.
As an improvement of the technical scheme, an acid liquid collector is arranged right below the air filtering sheet in the exhaust pipeline, so that acid liquid can be collected.
The utility model has the beneficial effects that:
1. the sealing between the surface piece and the battery shell is changed into a circle of glue groove type from a point type, so that the bonding line of the surface piece and the battery shell is completely sealed, the exhaust port is changed into a centralized type from an emission type, the exhaust gas is intensively discharged from the exhaust port, and the open fire can be prevented from entering from a gap between the surface piece and the battery shell to cause explosion.
2. By arranging the air filter below the air outlet, the material is PP, the ventilation flow is 500ml/min (20 ℃ +/-5 ℃, the effective diameter of the vent hole is 6-20 mm), so that the acid mist can be filtered, the waste gas is intensively discharged, and the air filter is also a barrier which can block open fire from entering the battery.
