Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries and relates to a measuring device for the amount of gas and acid mist discharged from batteries. Background Art

[0002] Lead-acid batteries are often in a constant voltage overcharge state during use. Due to the characteristics of lead-acid batteries, water will be electrolyzed when in an overcharged state. In the later stage of charging, most of the charging current is used to decompose water, so hydrogen and oxygen gases will be generated inside the battery and discharged to the outside of the battery. When hydrogen and oxygen gases are discharged from the battery, some sulfuric acid mist may overflow from the battery along with the gas.

[0003] When designing a vehicle, customers need to consider the amount of electrolyte dissolved in the battery when it is installed on the vehicle, the amount of electrolyte dissolved in the battery during use, and the impact of acid mist that overflows with gas on parts in extreme cases. This requires qualitative and quantitative analysis. The current method for testing the amount of electrolyte dissolved in the battery is to connect a gas flow meter to the outside of the battery exhaust hole, measure the gas volume, and calculate the liquid loss. For the measurement of acid mist that overflows with gas, it is generally only qualitatively determined by using a wet pH test paper, and no measurement is performed. Summary of the invention

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies in the prior art, thereby providing a device for measuring the amount of gas and acid mist discharged from a battery, which can collect the amount of gas discharged from a lead-acid battery and the amount of acid mist overflow at the same time, and perform quantitative measurement thereof respectively.

[0005] The technical solution of the utility model is: a device for measuring the amount of gas and acid mist discharged from a battery, comprising: a condenser, a volumetric bottle for collecting overflowed acid mist, and a flow meter for collecting exhaust gas;

[0006] The air inlet of the condenser is connected to the exhaust hole on one side of the battery placed on the placement table through the exhaust pipe, and the exhaust port is gradually tilted downward and connected to the volumetric flask through the connecting pipe;

[0007] The other two ports of the condenser are connected to the external circulating condensate;

[0008] One end of the flow meter is connected to the volumetric flask via a conduit;

[0009] The upper opening of the volumetric flask is provided with a rubber plug, and the rubber plug has a socket for inserting a connecting pipe and a catheter.

[0010] The placing table is made of stainless steel.

[0011] There is a positioning hole in the middle of the placement table for placing a volumetric flask.

[0012] The external circulating condensate of the condenser is cooling water, the lower port of the condenser is the water inlet of the external circulating condensate, and the upper port of the condenser is the water outlet of the external circulating condensate.

[0013] The flow meter is an electronic gas flow meter capable of measuring gas volume.

[0014] The use of testing equipment to analyze the exhaust volume of the battery under overcharge conditions and to collect and analyze the acid mist overflowing during the exhaust process is more conducive to cooperating with the OEM to evaluate the impact of the acid mist on the surrounding components of the battery than the current situation of only conducting qualitative analysis of the acid mist in the exhaust gas.

[0015] The utility model has a simple structure, can simultaneously measure the gas volume and the acid mist volume during the electrolysis of the electrolyte, can assist in calculating the electrolyte liquid volume loss, and can perform qualitative and quantitative analysis on the discharged acid mist.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] like Figure 1 As shown, the utility model is an embodiment of a measuring device for the amount of gas and acid mist discharged from a battery. The utility model comprises a condenser 3, a volumetric flask 5 and a flowmeter 7; the air inlet of the condenser 3 is connected to the exhaust hole on one side of the battery 1 placed on the placement table 8 through the exhaust pipe 2, the exhaust port is gradually inclined downward and then connected to the volumetric flask 5 through the connecting pipe 4, the upper port of the volumetric flask 5 is lower than the height of the exhaust hole of the battery, so as to prevent the acid mist from condensing into liquid through the condenser 3 and flowing back to the battery, causing inaccurate measurement, the other two ports of the condenser 3 are connected to the external circulation condensate, the condensate in the condenser is cooling water, the cooling water enters from the lower port of the condenser 3 and exits from the upper port to form a bottom-in and top-out; the overflowing acid mist is condensed from the gaseous state to the liquid state after being cooled by the condenser 3 and flows into the volumetric flask 5 with the connecting pipe 4 for collection and measurement, one side of the conduit 6 is connected to the volumetric flask 5, and the other side is connected to the flowmeter 7, the exhausted gas is measured by the flowmeter 7 after the acid mist is removed and then discharged into the air, the upper opening of the volumetric flask 5 is equipped with a rubber plug, and there is a socket on the rubber plug for inserting the connecting pipe 4 and the conduit 6. The placing table 8 is made of stainless steel, and has a positioning hole in the middle for placing the volumetric bottle 5.

[0019] After the battery 1 is produced, it is placed on the placement table 8, and one end of the exhaust pipe 2 is connected to the exhaust hole on one side of the battery 1, and the exhaust hole on the other side of the battery 1 is closed. The other end of the exhaust pipe 2 is connected to the air inlet of the condenser 3, and the air outlet of the condenser 3 is connected to the connecting pipe 4, and the other end of the connecting pipe 4 is connected to the volumetric flask 5.

[0020] When the battery 1 is subjected to an overcharge test, the electrolyte in the battery 1 is electrolyzed to generate hydrogen and oxygen. When the gas passes through the condenser 3, the acid mist in the gas is condensed by the condenser 3 and flows into the volumetric flask 5 through the gas outlet of the condenser 3 via the connecting hose 4. The gas without acid mist continues to be discharged through the conduit 6 and the flowmeter 7. The amount of discharged gas is counted by the flowmeter 7, and the acid liquid carried in the discharged gas is collected and measured by the volumetric flask 5. Finally, the concentration of the acid liquid in the volumetric flask 5 can be analyzed.

The utility model has the characteristics of simple structure, can simultaneously collect and measure the gas and acid mist during the electrolysis of the electrolyte, can quickly calculate the loss of electrolyte volume and discharge acid mist for qualitative and quantitative analysis.
