Description

Technical Field

[0002] Electrolyte is a medium used in chemical batteries, electrolytic capacitors, etc., and its representative content varies greatly in different industries. There are electrolytes in organisms (also called electrolytes), electrolytes used in the battery industry, and electrolytes in industries such as electrolytic capacitors and supercapacitors. The components of electrolytes used in different industries vary greatly, or even completely different. For example, the electrolyte in the human body is mainly composed of water, sodium chloride, PH buffer substances, etc. The electrolyte of aluminum electrolyte capacitors contains GBL and other main solvents, the electrolyte of supercapacitors contains propylene carbonate or acetonitrile as the main solvent, the electrolyte of lithium manganese primary batteries contains propylene carbonate, ethylene glycol dimethyl ether and other main solvents, and the electrolyte of lithium ion batteries contains ethylene carbonate, dimethyl carbonate, methyl ethyl carbonate and diethyl carbonate as the main solvents. Their respective conductive salts are also completely different, such as sodium chloride in the human body, tetraethylammonium tetrafluoroborate in supercapacitor electrolytes, lithium perchlorate or lithium trifluoromethanesulfonate are commonly used in lithium manganese primary batteries, and lithium hexafluorophosphate in lithium ion batteries.

At the same time, the worm gear transmission is used to realize the rotation of the crushing roller 24, and the belt transmission is used to realize the rotation of the separation barrel 22.

[0038] The outer side of the collection box 1 is fixedly connected with a mounting frame 7, and the side wall of the mounting frame 7 is fixedly connected with a driving motor 8 for driving the conveying rod 3 and the transmission mechanism;

[0039] The side wall of the collecting box 1 is provided with a flushing mechanism connected to the crushing roller 24, and the flushing mechanism includes a water storage tank 29 fixedly connected to the side wall of the collecting box 1, and a water pump 30 is fixedly connected to the inner side of the water storage tank 29, and a water pipe 28 is fixedly connected to the output end of the water pump 30.

[0040] The collecting box 1 is divided into a conveying chamber 2, a crushing chamber 33 and a separation chamber 32 from top to bottom through a partition 26 and a guide plate 23. The conveying rod 3 is located in the conveying chamber 2, the crushing roller 24 is located in the crushing chamber 33, and the separation barrel 22 is located in the separation chamber 32, so as to facilitate the integration of conveying, crushing and separation.

[0041] Working principle:

[0042] First, the driving motor 8 is started, and then the battery is put into the conveying chamber 2 through the feeding port 5. The output shaft of the driving motor 8 rotates to drive the conveying rod 3 to rotate, and the conveying rod 3 rotates to drive the two spiral conveying blades 4 to rotate, so that the battery can be conveyed to the through hole and fall into the crushing chamber 33;

[0043] When the conveying rod 3 rotates, the first bevel gear 6 and the second bevel gear 9 are used to realize the rotation of the rotating shaft 13. The rotation of the rotating shaft 13 drives the worm tooth groove 12. Under the transmission action of the worm tooth groove 12 and the worm wheel 11, one of the crushing rollers 24 is rotated. Then, the two crushing rollers 24 are rotated through the gear transmission of the two gears 10, so that the batteries dropped into the crushing chamber 33 can be crushed, and the crushed batteries fall into the separation barrel 22 through the guide plate 23;

[0044] While the rotating shaft 13 rotates, the vertical rod 20 is synchronously rotated by the first transmission wheel 15, the transmission belt 17, and the second transmission wheel 18. The rotation of the vertical rod 20 drives the separation barrel 22 to rotate, so that the electrolyte can be thrown out from the filter holes on the side, and the solid matter in the battery is left in the separation barrel 22. After all the treatment is completed, the electrolyte is discharged and collected through the discharge port 31.

[0045] When the collecting box 1 needs to be cleaned, when the driving motor 8 is running, the switch of the water pump 30 is turned on, and the water pump 30 pumps clean water into the water injection chamber 34 through the water pipe 28, and then sprays it through the water spray port 25. During the rotation of the crushing roller 24, the water spraying can fully rinse the crushing roller 24 and the crushing chamber 33. The rinsed water flows into the separation barrel 22, and is thrown out during the rotation of the separation barrel 22, so that the separation barrel 22 and the separation chamber 32 can be cleaned, and finally flows out through the discharge port 31.

[0046] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
