Description

Technical Field

[0001] The utility model relates to the technical field related to motorcycle batteries, in particular to an acid extraction device for motorcycle batteries. Background Art

[0002] Valve-regulated sealed lead-acid batteries are of lean liquid design. Due to differences in technology, process, materials, etc., rich liquid filling is used in actual production. The battery is in a rich liquid state, which is beneficial to the electrochemical reaction of the battery during charging and discharging. In order to meet the lean liquid state of the battery, the battery is subjected to constant voltage or constant current in the later stage of charging, and the excess acid is extracted to make the battery meet a certain lean liquid state.

[0003] If the acid is extracted unevenly in each cell, with more acid in some cells and less acid in others, that is, the acid saturation of each cell is different, it will affect the internal oxygen cycle of the battery, not only making the battery performance inconsistent and affecting the battery's charging acceptance performance, but also causing individual batteries to lag behind when multiple batteries are used in series, affecting the service life of the battery pack; in severe cases, the battery may also experience acid creep and leakage.

[0004] At present, the acid extraction operation is that workers hold one or two straws to repeatedly extract the acid from a battery to ensure that the acid in the battery is completely extracted, and then ensure that each cell is in a lean liquid state, which consumes a lot of manpower and has extremely low production efficiency. Therefore, there is an urgent need for an acid extraction device that can completely extract the rich liquid acid in each cell of the battery at one time. Utility Model Content

[0005] The utility model aims to provide a motorcycle battery acid extraction device to improve the acid extraction efficiency.

[0006] To this end, the technical solution adopted by the utility model is: a motorcycle battery acid extraction device, comprising a shell, a row of acid extraction tubes arranged below the shell and a buffer cavity arranged above the shell, an acid storage box is arranged in the shell corresponding to each acid extraction tube, the upper ends of the acid extraction tubes extend into the middle and upper parts of the corresponding acid storage boxes respectively, the top end of each acid storage box is connected to the buffer cavity through the buffer tube, the upper end of the buffer tube extends to the upper part of the buffer cavity, and a vacuum hole is arranged in the upper part of one end of the buffer cavity to be connected to the vacuum extraction device.

[0007] More preferably, the housing is provided with an observation window for observing the water level in the acid storage box. The amount of the acid solution in the acid storage box inside the housing can be directly observed through the observation window.

[0008] Preferably, a detachable sealing end cap is provided on one side of the housing. The acid liquid extracted by the acid extraction tube is stored in the acid storage box, and the liquid level of the acid liquid in the acid storage box is observed through the observation window. When the liquid level is high, the sealing end cap is opened to pour out the acid liquid in the acid storage box.

[0009] More preferably, the number of the acid extraction tubes and the number of the acid storage boxes are both six.

[0010] More preferably, the vacuum extraction device includes a vacuum extraction pipeline, a buffer bottle and a vacuum pipeline, one end of the vacuum extraction pipeline is connected to the buffer chamber, and the other end is connected to the upper end of the buffer bottle, and the upper part of the buffer bottle is also provided with a vacuum pipeline connected to a vacuum pump. Acid is extracted through the vacuum pipeline and the vacuum pump, and a buffer bottle and a vacuum extraction pipeline are provided during the acid extraction process to collect a small amount of acid liquid, so as to avoid acid from entering the vacuum pump and corroding the pump as much as possible.

[0011] The utility model has the following beneficial effects: the tops of the acid extraction tubes are all connected to the same buffer cavity through the acid storage box, so that the suction force of each acid extraction tube is roughly the same, thereby ensuring uniform acid extraction; through vacuum extraction, the rich liquid acid in each cell of the battery can be extracted cleanly at one time, and in the process of acid extraction, the acid extracted by the acid extraction tube is stored in the acid storage box, and since the acid extraction tube extends to the middle and upper part of the acid storage box, as long as the liquid level in the acid storage box is lower than the upper end of the acid extraction tube, the liquid in the acid storage box will not flow back from the acid extraction tube; at the same time, the buffer tube extends to the upper part of the buffer cavity, so that the acid in the acid storage box can be prevented from entering the buffer cavity as much as possible, and even if a small amount of acid is drawn into the buffer cavity, it can be ensured that the acid in the buffer cavity does not flow back into the acid storage box; then we set up a buffer bottle to collect a small amount of acid that has been extracted, so as to prevent the acid from entering the vacuum pump and corroding the pump as much as possible, and the collected acid can be reused after treatment, thereby saving resources.

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a motorcycle battery acid extraction device comprises a housing 1, a row of acid extraction tubes 2 arranged below the housing 1, and a buffer chamber 4 arranged above the housing 1. An acid storage box 3 is arranged in the housing 1 corresponding to each acid extraction tube 2, and an observation window 9 for observing the water level in the acid storage box 3 is opened on the housing 1. The amount of acid in the acid storage box 3 inside the housing 1 can be directly observed through the observation window 9.

[0016] The number of the acid extraction tube 2 and the acid storage box 3 are both six. A detachable sealing end cap 10 is provided on one side of the housing 1. The acid liquid extracted by the acid extraction tube 2 is stored in the acid storage box 3, and the liquid level of the acid liquid in the acid storage box 3 is observed through the observation window 9. When the liquid level is high, the sealing end cap 10 is opened to pour out the acid liquid in the acid storage box 3.

[0017] The upper ends of the acid extraction tubes 2 extend into the middle and upper parts of the corresponding acid storage boxes 3. The top end of each acid storage box 3 is connected to the buffer cavity 4 through a buffer tube 5. The upper end of the buffer tube 5 extends to the upper part of the buffer cavity 4. A vacuum hole is provided at the upper part of one end of the buffer cavity 4 and is connected to a vacuum extraction device.

[0018] The vacuum extraction device includes a vacuum extraction pipeline 6, a buffer bottle 7 and a vacuum pipeline 8. One end of the vacuum extraction pipeline 6 is connected to the buffer chamber 4, and the other end is connected to the upper end of the buffer bottle 7. A vacuum pipeline 8 connected to a vacuum pump is also provided on the upper part of the buffer bottle 7. Acid is extracted through the vacuum pipeline 8 and the vacuum pump, and a buffer bottle 7 and a vacuum extraction pipeline 6 are provided during the acid extraction process to collect a small amount of acid liquid, so as to avoid acid from entering the vacuum pump and corroding the pump as much as possible.

[0019] The tops of the acid extraction tubes 2 are all connected to the same buffer chamber 4 through the acid storage box 3, so that the suction force of each acid extraction tube 2 is roughly the same, ensuring uniform acid extraction; through vacuum extraction, the rich liquid acid in each cell of the battery can be extracted cleanly at one time, and in the process of acid extraction, the acid extracted by the acid extraction tube 2 is stored in the acid storage box 3. Since the acid extraction tube 2 extends to the middle and upper part of the acid storage box 3, as long as the liquid level in the acid storage box 3 is lower than the upper end of the acid extraction tube 2, the liquid in the acid storage box 3 will not flow back from the acid extraction tube 2; at the same time, the buffer tube 5 extends to the upper part of the buffer chamber 4, so that the acid in the acid storage box 3 can be prevented from entering the buffer chamber 4 as much as possible, even if a small amount of acid is drawn into the buffer chamber 4, it can be ensured that the acid in the buffer chamber 4 does not flow back into the acid storage box 3; then we set up a buffer bottle 7 to collect a small amount of acid that is extracted, to prevent the acid from entering the vacuum pump and corroding the pump as much as possible, and the collected acid can be reused after treatment, saving resources.
