Description

Technical Field

[0001] The invention belongs to a process for extracting residual acid from a battery, and in particular relates to a device for extracting acid from a battery. Background Art

[0002] Maintenance-free batteries, as the name suggests, require no additional maintenance, making them environmentally friendly. A safety valve controls the battery's internal oxygen recombination during charge and discharge, allowing for partial gas release only when high pressure is reached. Maintenance-free batteries require a float charge at the end of the formation phase, during which residual acid is removed from the battery via an external negative pressure extraction line.

[0003] Lead-acid batteries require extraction of excess acid in the later stages of the charging and formation phase. This extraction process utilizes specialized tools with internal negative pressure and consists of several extraction tubes. These tubes are inserted directly into the upper partition of the battery cell group to extract the acid. Over time, these tubes can become easily worn or damaged and require replacement. Operators are often careless and fail to calibrate the replacement tubes, resulting in varying lengths. This can lead to incomplete extraction of excess acid from the battery cell with the shorter tube. The extraction mechanism is crucial; incomplete extraction can hinder oxygen recombination reactions, leading to battery performance degradation and quality issues. Therefore, improvements to existing technologies are necessary to address these challenges. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a device for extracting acid from batteries to solve the problems in the background technology. The operation method is practical, simple, convenient and fast. There are quantitative standards for adapting acid extraction tubes, which ensures the consistency of the length of the acid extraction tubes and the consistency of the residual acid extracted from the batteries, improves the oxygen recombination reaction of the batteries, and extends the battery life.

[0005] The present invention is achieved through the following technical solutions:

[0006] A device for extracting acid from batteries includes an acid extraction body, a negative pressure suction pipe disposed therein, a quick-connect pipe fixedly connected to the end of the negative pressure suction pipe, and an air compressor. A plurality of acid-absorbing fixed blocks are fixed to the circumferential surface of the negative pressure suction pipe, the acid-absorbing fixed blocks being in communication with the negative pressure suction pipe. A sealing rubber plug is inserted into the acid-absorbing fixed block, and an acid-extraction pipe is disposed within the sealing rubber plug. The end of the acid-extraction pipe is provided with a plurality of side holes. When in use, the side holes are arranged longitudinally along a separator of the battery to be extracted.

[0007] A further improvement of the present invention is that the acid extraction tube and the sealing rubber plug are interference fit.

[0008] A further improvement of the present invention is that the side holes are arranged at equal angles around the wall of the acid extraction tube.

[0009] A further improvement of the present invention is that all of the acid-absorbing fixed blocks are located on the same straight line.

[0010] A further improvement of the present invention is that it further comprises a calibration component, which is used to calibrate the acid extraction tube.

[0011] A further improvement of the present invention is that the calibration assembly includes a calibration block, the side of the calibration block is L-shaped, and when in use, the side of the calibration block calibrates the tube wall of the acid extraction tube, and the bottom of the calibration block calibrates the bottom of the acid extraction tube. The calibration block includes a boss, and when in use, the acid absorption fixing block is flush with the upper surface of the boss.

[0012] A further improvement of the present invention is that there is a certain inclination angle between the bottom surface of the calibration block and the calibration block, and the inclination angle ranges from 2 to 3 degrees.

[0013] Compared with the prior art, the device for extracting acid from a battery disclosed in the present invention has the following obvious advantages:

[0014] 1. A device for extracting acid from a battery. The acid suction fixed block is plugged with a sealing rubber plug. An acid extraction tube is provided inside the sealing rubber plug. The acid extraction tube and the sealing rubber plug have an interference fit. The acid extraction tube can be easily removed from the sealing rubber plug to achieve quick disassembly while ensuring sealing during use.

[0015] 2. A device for extracting acid from batteries, wherein a plurality of side holes are provided at the end of an acid extraction tube, each of which is arranged at equal angles around the tube wall of the acid extraction tube. Acid extraction is performed through the side holes, and the side suction method is used without damaging the battery separator.

[0016] 3. A device for extracting acid from batteries, comprising a calibration assembly, the calibration assembly including a calibration block, the side of the calibration block being L-shaped. When in use, the side of the calibration block is calibrated with the wall of the acid extraction tube, and the bottom of the calibration block is calibrated with the bottom of the acid extraction tube. The calibration block includes a boss. When in use, the acid extraction fixing block is flush with the upper surface of the boss. The acid extraction tube provided by the calibration assembly is shortened from the farthest end to the proximal end. In this way, when employees extract the batteries on the top layer of the charging rack, the acid extraction tube has an inclination, which is more conducive to the employees' manual grasping operation.

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-6 As shown, this embodiment provides a device for extracting acid from a battery, including an acid extraction body 1, a negative pressure suction pipe 2 is provided in the acid extraction body 1, the end of the negative pressure suction pipe 2 is fixedly connected to a quick-connect pipe 12, the quick-connect pipe 12 is connected to an air compressor, three acid-absorbing fixed blocks 13 are fixed on the circumferential surface of the negative pressure suction pipe 2, the acid-absorbing fixed blocks 13 are connected to the negative pressure suction pipe 11, a sealing rubber plug 14 is plugged on the acid-absorbing fixed block 13, an acid-extraction tube 15 is provided in the sealing rubber plug 14, and a plurality of side holes 16 are provided at the end of the acid-extraction tube 15. When in use, the side holes 16 are arranged longitudinally along the partition of the battery to be extracted.

[0028] The acid extraction tube 15 is interference-fitted with the sealing rubber plug 14 , so the acid extraction tube 15 can be easily removed from the sealing rubber plug 14 , achieving quick disassembly while ensuring sealing during use.

[0029] The side holes 16 are arranged at equal angles around the wall of the acid extraction tube 15 , which can ensure that the acid extraction tube 15 extracts acid evenly during acid extraction.

[0030] All the acid-absorbing fixed blocks 13 are located on the same straight line to ensure uniform disassembly.

[0031] The device further comprises a calibration component, which is used to calibrate the acid extraction tube 15 .

[0032] The calibration assembly includes a calibration block 2, and the side surface 21 of the calibration block 2 is L-shaped. When in use, the side surface 21 of the calibration block 2 calibrates the tube wall of the acid extraction tube 15, and the bottom surface 22 of the calibration block 2 calibrates the bottom of the acid extraction tube 15. The calibration block 2 includes a boss 23. When in use, the acid absorption fixing block 12 is flush with the upper surface of the boss 23.

[0033] The acid extraction tube 15 provided by the calibration component is shortened from the farthest end to the proximal end. In this way, when employees suck the batteries on the top layer of the charging rack, the acid extraction tube 15 has an inclination, which is more conducive to the manual grasping operation of the employees.

[0034] There is a certain inclination angle between the bottom surface 22 of the calibration block 2 and the calibration block 2, and the inclination angle ranges from 2 to 3 degrees.

[0035] The main working process of a device for extracting acid from a battery of the present invention is as follows:

[0036] The tools needed are: utility knife, gloves (cotton inner and rubber outer), soapy water, and stainless steel cylindrical iron rod.

[0037] Step 1: Put on gloves, select the acid extraction tube 15, and dip the root of the acid extraction tube 15 into soapy water (for lubrication and easy insertion and removal);

[0038] Step 2: First adapt the first acid extraction tube 15 at the farthest end, then place the acid extraction body 1 on the calibration block 2 to see if the acid extraction tube 15 is adapted. If it is too short, pull it out and place it at the nearest end before adapting it. If it is too long, use a utility knife to cut off the excess tube length. Note that the acid extraction tube 15 must be pulled out and the root cut.

[0039] Step 3: Follow the method to adapt the second tube until the last tube is adapted.

[0040] The fourth step: must ensure that the pipe heads of all acid extraction pipes 15 are in a straight line. Finally, use a stainless steel cylindrical iron rod to adjust the direction of the side hole, according to the longitudinal direction of the internal separator of each battery.

[0041] After completing the adaptation and calibration work, the quick-connect pipe 12 is connected to the air compressor to realize the acid extraction operation of the battery, and the acid in the battery can be extracted into the negative pressure suction pipe 11.

[0042] The circuits, electronic components and control modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.
