Description

Technical Field

[0001] The invention relates to the technical field of battery production, and in particular to a production process of a lead-carbon battery with high energy density and long life. Background Art

[0002] In today's era, most countries in the world are vigorously promoting the development of new energy vehicles with high energy efficiency, low emissions and good energy-saving effects. The prerequisite for the development of new energy vehicles is to have a suitable on-board power supply. Lead-carbon batteries are a new type of battery developed on the basis of lead-acid batteries. Lead-carbon batteries have the high energy density of lead-acid batteries and the high power density of supercapacitors, which is equivalent to a mixture of the two. They can be widely used in areas where conventional batteries cannot be used, such as those that require rapid energy recovery and long-term undercharging.

[0003] Existing lead-carbon batteries are generally made of lead dioxide as the positive electrode lead paste, which is coated on the positive electrode grid and then dried. It is mainly formed by mixing lead powder, water, sulfuric acid, graphite, phosphoric acid, magnesium sulfate and other raw materials to form the positive electrode lead paste. Its charging and discharging speed is relatively slow, and during the discharge process of the lead-carbon battery, lead dioxide reacts with the electrolyte sulfuric acid to generate lead sulfate with large particles, difficult to dissolve and poor conductivity, which leads to a gradual decrease in the energy storage of the lead-carbon battery and continuous battery degradation.

[0051] Among them, a cam 5 is preferably fixedly provided on the telescopic thick rod 3, and two symmetrically arranged magnetic blocks 21 are fixedly provided on the lower surface of the cam 5, and the magnetism of the two magnetic blocks 21 on the side away from the cam 5 is opposite, and a lifting plate 8 is rotatably connected to the telescopic thin rod 11, and two symmetrically arranged magnetic blocks 22 are fixedly provided on the upper surface of the lifting plate 8, and the magnetism of the side of the magnetic block 22 away from the lifting plate 8 is opposite, and the magnetic block 1 21 cooperates with the magnetic block 2 22, and a plurality of springs 9 are fixedly provided on the lower surface of the lifting plate 8, and the other end of the spring 9 is fixedly provided on the upper surface of the mixing box 10.

[0052] Among them, the preferred device shell is symmetrically fixed with an air inlet box 7, and the side wall of the air inlet box 7 that is far away from each other is connected with a one-way air inlet pipe 16 and a one-way air outlet pipe 14, and the one-way air inlet pipe 16 and the one-way air outlet pipe 14 extend out of the device shell; a movable plate 20 is slidably connected in the air inlet box 7, and a push rod 19 is fixedly arranged on the side where the two movable plates 20 are close to each other, and the push rod 19 slidably extends out of the air inlet box 7, and a push plate 17 is fixedly connected on the side where the push rods 19 are close to each other, and a return spring 18 is also wound around the push rod 19, one end of the return spring 18 is fixedly connected to the push rod 19, and the other end of the return spring 18 is fixedly connected to a side wall of the air inlet box 7 that is close to each other, and the push plate 17 cooperates with the cam 5;

[0053] The other end of the one-way air outlet pipe 14 extends from the lower side of the device shell into the mixing box 10. The mixing box 10 is also connected with an exhaust pipe 6, which extends upward out of the device shell. A plurality of support rods 12 are also fixedly provided on the lower surface of the device shell.

[0054] Among them, the mixing box 10 and the lower surface of the device shell are provided with a discharge port. After the negative electrode lead paste is made, the discharge port is opened to take out the negative electrode lead paste, and then clean water is poured into the mixing box 10 through the feeding funnel 2 and the feeding pipe 15 to clean it; after the cleaning is completed and the water is controlled, the material for making the positive electrode lead paste is poured again through the feeding funnel 2 and the feeding pipe 15. The specific cleaning method can be decided by technicians in this field and users.

[0055] The working principle and beneficial effects of the above technical solution are as follows: the material for making negative electrode lead paste or positive electrode lead paste enters the mixing box 10 through the feeding funnel 2 and the feeding pipe 15, the driving motor 4 is started, the driving motor 4 drives the telescopic thick rod 3 and the telescopic thin rod 11 to start rotating, the telescopic thin rod 11 drives a plurality of stirring rods 13 to stir the material in the mixing box 10, when the telescopic thick rod 3 rotates, the telescopic thick rod 3 drives the cam 5 to rotate, and the two magnetic blocks 1 21 on the cam 5 continuously match the two magnetic blocks 2 22 on the lifting plate 8 during the rotation process. When the magnets 1 21 and 2 2 on the same side are opposite in magnetism, the lifting plate 8 will be close to the cam 5, and when the magnets 1 21 and 2 2 on the same side are the same in magnetism, the lifting plate 8 will be away from the cam 5. When the magnets 1 21 and 2 2 do not cooperate, the spring 9 will drive the lifting plate 8 to reset, and because the cam 5 is constantly rotating, the lifting plate 8 will continuously move up and down, so that the telescopic thin rod 11 moves up and down in the telescopic thick rod 3, and the plurality of stirring rods 13 move up and down in the mixing box 10, so that the stirring effect of the stirring rods 13 is better.

[0056] At the same time, during the rotation of the cam 5, the cam 5 will intermittently contact the push plate 17. When the cam 5 contacts the push plate 17, the push plate 17 drives the push rod 19 to move, and the push rod 19 drives the moving plate 20 to squeeze the air in the air intake box 7 into the one-way air outlet pipe 14, and then the air will enter the mixing box 10 from the lower part of the mixing box 10, further stirring the materials in the mixing box 10, and then the air will be discharged from the exhaust pipe 6. When the cam 5 is not in contact with the push plate 17, the moving plate 20 and the push rod 19 are reset under the action of the reset spring 18, and the air enters the air intake box 7 through the one-way air intake pipe 16; by setting a driving motor 4, the stirring rod 13 can be stirred and mixed while the stirring rod 13 can be moved up and down, and the air is introduced at the same time. The introduction of air causes the materials in the mixing box 10 to tumble, thereby realizing the superposition of triple mixing, and the mixing speed is faster and the homogenization is better.

Racks 24 are fixedly provided on the left and right side walls of the drying box 23, and the gear 25 cooperates with the rack 24. A clamping assembly is provided on the side where the limiting blocks 31 are close to each other, and the clamping assembly cooperates with the clamping plate 40.

[0061] Among them, an opening and closing door is arranged on the front side of the drying box 23; the snap-fit ​​assembly can be a common snap-fit ​​assembly on the market, and only the snap-fit ​​of the limit block 31 and the clamping plate 40 needs to be completed.

[0062] The working principle and beneficial effects of the above technical solution are as follows: open the opening and closing door, place a number of negative plates between the two clamping plates 40 on the left, then move the clamping plates 40 toward each other, the clamping plates 40 clamp the negative plates, then the clamping assembly on the left limit block 31 is clamped with the clamping plates 40, that is, the limit of the negative plates is completed;

[0063] Similarly, a number of positive plates are placed between the two clamping plates 40 on the right side, and then the clamping plates 40 are moved toward each other, the clamping plates 40 clamp the positive plates, and then the clamping assembly on the right limit block 31 is clamped with the clamping plate 40, that is, the positive plate is limited; (the positive plate can also be placed between the two clamping plates 40 on the left side, and the placement of the positive plate and the negative plate can be determined by the user, but the positive plate and the negative plate cannot be mixed, and mixed loading may cause the positive lead paste to transfer to the negative plate or the negative lead paste to transfer to the positive plate);

[0064] The electric heating wire 42 and the power motor 37 are started, and the electric heating wire 42 gradually heats up the gas in the high-temperature box 35. The power motor 37 drives the C-shaped rod 36 to rotate, and the C-shaped rod 36 drives the first connecting rod 45 to move. The first connecting rod 45 drives the second connecting rod 43 to slide (similar to a crank-connecting rod mechanism), and the second connecting rod 43 drives the air push plate 41 to push the hot air in the high-temperature box 35 into the one-way air guide hose 44, and then the hot air enters the hollow tank 46. Thereafter, the hot air enters the hollow rod 34 from the plurality of through holes on the hollow rod 34, and then is discharged into the drying box 23 through the jet pipe 29 on the air outlet pipe 27, thereby drying the positive and negative plates in the drying box 23;

[0065] When the hollow rod 34 rotates, the hollow rod 34 drives the reciprocating screw 30 to rotate, the reciprocating screw 30 drives the moving block 33 to move up and down, the moving block 33 drives the clamping plate 40 to move up and down, the clamping plate 40 drives the limit block 31, the rotating shaft 32 and the gear 25 to move up and down, when the gear 25 moves up and down, due to the cooperation between the gear 25 and the rack 24, the gear 25 will rotate, the rotation of the gear 25 drives the rotating shaft 32 to rotate, the rotation of the rotating shaft 32 drives the limit block 31 to rotate, and the limit block 31 drives the clamping plate 40. The clamping plate 40 drives the rotating block 26 to rotate, so that the positive plate and the negative plate can be turned over while moving up and down, so that the drying efficiency of the positive plate and the negative plate is faster;

[0066] The jet pipe 29 and the air outlet pipe 27 are inclined at an angle of 45 degrees, and the upper and lower air outlet pipes 27 are symmetrical along the center position of the drying box 23, so that a ring-shaped airflow can be formed in the drying box 23, and the drying speed will be faster; by setting a power motor 37, hot air can be introduced into the drying box 23, and the positive and negative plates can be moved up and down and rotated, which effectively improves the drying rate of the device, and has strong practicality and functionality.

[0067] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. If these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
