Description

Technical Field

[0001] The invention relates to the technical field of lead-acid batteries, and in particular to a process for recycling waste batteries of new energy vehicles. Background Art

[0002] Wasted new energy vehicle power batteries refer to power batteries whose remaining capacity or charge-discharge performance after use cannot guarantee the normal driving of new energy vehicles, or power batteries that are no longer used after being dismantled for other reasons. While power batteries bring convenience to people's lives, they also have a very large negative impact on the living environment. In order to reduce resource waste and improve economic benefits, it is necessary to recycle waste batteries.

[0003] There are many existing technologies for battery recycling, such as: Chinese patent publication number CN118281392A discloses a grading recovery device for waste lead-acid batteries, which relates to the technical field of lead-acid batteries, comprising: a conversion belt, on which a number of casting mold mechanisms are equidistantly installed, and the casting mold mechanisms include a casting plate, a push slide, a guide rod, a first spring, a flip groove and a flip block; a moving mechanism slides on the top surface of the casting plate, and the moving mechanism includes a moving base and a moving slider; a debris removal mechanism is installed on the moving base, and the debris removal mechanism includes a recovery bucket, a relay shovel, a rotating shaft and a debris removal plate; a material spreading mechanism is installed in the recovery bucket, and the material spreading mechanism includes a roller, a first gear, a side plate and a flip plate; the application has the advantages of automatically and stably scraping off sodium salt, replacing the workers' sodium salt removal operation, reducing the workers' workload and safely transferring sodium salt, and avoiding sodium salt or lead liquid from polluting the working environment.

[0004] It can be seen that in the prior art, when transferring the sodium salt floating on the lead liquid, in order to reduce the workload of workers and ensure the safe transfer of the sodium salt, a cleaning plate is usually used to slide in the mold groove to quickly remove the sodium salt floating on the surface of the lead liquid. Since the cleaning plate is arranged in an inclined state, that is, during the movement of the cleaning plate, the sodium salt slides along the cleaning plate to the recovery bucket. When the drooping end of the cleaning plate moves to contact the inner wall of the mold groove, there is still a part of the sodium salt above the cleaning plate that has not been completely guided to the recovery bucket, which affects the recovery rate of the sodium salt and reduces the purity of the lead ingot. In addition, during the process of the casting mold plate being turned over to an inverted state, the cleaning plate falls on the workbench, affecting the working environment.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] like Figure 1-Figure 6 As shown, a recycling process for waste batteries of new energy vehicles is provided, comprising a turning belt 100 and a guide belt 101 installed on the side of the turning belt 100, a plurality of casting templates 110 are arranged at equal distances on the turning belt 100, a power mechanism 120 is arranged on the side wall of each casting template 110, and a cleaning mechanism is arranged in the casting groove of the casting template 110, and the power mechanism 120 is used to push the cleaning mechanism to move when moving along the guide belt 101, and the specific steps are as follows: S1, the turning belt 100 is rotated at a constant speed, and the feeding device is an existing device, which is not designed on the top surface of the turning belt 100 in the drawings, to provide lead liquid for each casting plate 110 passing through; S2, the power mechanism 120 drives the impurity removal mechanism to move in the casting mold tank to scrape off the sodium salt floating on the lead liquid; S3, when the casting plate 110 at the position is rotated to an inverted state, the lead blocks formed in the casting groove fall off from the casting plate 110 for recovery, and the power mechanism 120 is reset; The impurity removal mechanism cooperates with the casting mold groove, and the impurity removal mechanism includes an impurity removal plate 140 and a recovery plate 141 rotatably connected to the impurity removal plate 140. The recovery plate 141 is fixedly connected to the power mechanism 120. The end of the casting mold plate 110 is provided with a gas collecting chamber 111 and a piston chamber 112. The gas collecting chamber 111 is connected to the piston chamber 112, and the gas collecting chamber 111 is connected to the power mechanism 120. When the power mechanism 120 moves along the track of the guide belt 101, the power mechanism 120 is used to remove the impurity in the power mechanism 120. The air in the air collecting chamber 111 is pushed into the piston chamber 112 for storage, and the air in the air collecting chamber 111 flows into the piston chamber 112. The piston chamber 112 is provided with an ejection mechanism 200. The air pushed by the power mechanism 120 is used as a power to push the ejection mechanism 200 to move upward, so that the ejection mechanism 200 drives the impurity removal plate 140 to turn over, so as to realize the dumping of the sodium salt on the impurity removal plate 140 into the recovery plate 141, thereby improving the recovery effect of the sodium salt and avoiding mixing with the lead ingots to affect the recovery quality of the lead ingots.

[0023] Therefore, on the basis of the above structure, the structure of the power mechanism 120 is disclosed. The power mechanism 120 includes a power rod 121 and a piston plate 122 coaxially connected to the power rod 121. The outer portion of the piston plate 122 is sleeved with a piston cylinder 130 fixed to the side wall of the casting template 110. The piston cylinder 130 is connected to the air collecting chamber 111, and a return spring 131 is arranged inside the piston cylinder 130 at one end away from the power rod 121, which is against the piston plate 122. The power rod 121 is in contact with the guide belt 101. In this way, during the lead ingot recovery process, the flip belt 100 drives multiple casting templates 110 to move, the power rod 121 slides along the guide belt 101, and the feeding device injects lead liquid into each casting template 110. Under the action of the guide belt 101, the power rod 121 gradually pushes the piston plate 122 to compress the return spring 131, so that the elastic potential energy of the return spring 131 increases, and the piston plate 122 pushes the air in the piston cylinder 130 into the air collecting chamber 111 for storage.

[0024] Secondly, the air collecting chamber 111 is internally sleeved with a counterweight plate 115, which is higher than the connection between the piston cylinder 130 and the air collecting chamber 111. The air collecting chamber 111 and the piston chamber 112 are connected through an air supply channel, and a pressure relief valve is provided inside the air supply channel.

[0025] refer to Figure 5 As shown, since the air collecting chamber 111 is connected to the outside, in the process of using the air pushed into the air collecting chamber 111 to translate the counterweight plate 115 upward, under the action of the pressure relief valve inside the gas supply channel, the counterweight plate 115 discharges the air inside the air collecting chamber 111 to the outside, and the air does not flow into the gas supply channel, and the gas inside the air collecting chamber 111 is in a compressed state.

[0026] In addition, if the air pushed into the air collecting chamber 111 by the piston plate 122 is not sufficient to make the counterweight plate 115 translate upward to contact the top inner wall of the air collecting chamber 111, gas can be added to the air collecting chamber 111 through an external air replenishing device (such as an air pump), thereby providing power for pushing the counterweight plate 115 and the ejection mechanism 200.

[0027] Then, when the counterweight plate 115 rises to a point higher than the connection between the gas supply channel and the gas collecting chamber 111 (that is, the counterweight plate 115 is now in contact with the inner wall of the top of the gas collecting chamber 111 and cannot move further), the piston plate 122 continues to move one end distance until the return spring 131 is compressed to the maximum stroke, and the impurity removal plate 140 moves to the end of the mold groove, and the air pressure inside the gas collecting chamber 111 reaches the maximum. At this point, the air pressure inside the gas collecting chamber 111 breaks through the pressure relief valve provided in the gas supply channel, and the gas in the gas collecting chamber 111 flows into the piston chamber 112 through the gas supply channel. At this time, the gas instantly discharged from the pressure relief valve causes the ejection mechanism 200 to eject upward, providing power for pushing the impurity removal plate 140 to flip later.

[0028] During the movement of the power rod 121, the power rod 121 will also drive the impurity removal plate 140 and the recovery plate 141 to move synchronously. The reason is that the power mechanism 120 also includes a support rod 123 fixedly connected to the power rod 121, and the end of the support rod 123 away from the power rod 121 is fixedly connected to an arch frame 124, and the arch frame 124 is fixedly connected to both sides of the recovery plate 141. First arc springs 143 are arranged on both sides of the arch frame 124, and the other end of the first arc spring 143 is fixedly connected to the impurity removal plate 140. The impurity removal plate 140 at the sodium salt inlet protrudes upward to limit the reverse movement of the sodium salt.

[0029] Moreover, during the movement of the power rod 121, the power rod 121 will also drive the support rod 123 to move the arch frame 124. During this process, the first arc springs 143 on both sides of the arch frame 124 provide support for the protruding rod 142. The protruding rod 142 transfers the sodium salt floating on the lead liquid. Under the guidance of the protruding rod 142, the sodium salt slides into the recovery plate 141. Under the action of the recovery plate 141, the sliding sodium salt is directed to both sides, so that the sodium salt stays on the recovery plate 141 for a short time.

[0030] Secondly, when the impurity removing plate 140 is in an inverted state, the impurity removing plate 140 is closely attached to the lead ingot under the action of the first arc spring 143. At the same time, the power rod 121 and the impurity removing plate 140 move in the opposite direction. In this way, the sodium salt and lead liquid remaining on the starting end of the mold groove can be scraped off during the reverse movement of the impurity removing plate 140, so that the surface of the casting mold plate 110 can be kept clean.

[0031] When the impurity removing plate 140 moves from the beginning to the end of the mold groove, the impurity removing plate 140 contacts the mold groove, that is, the impurity removing plate 140 stops moving at this time, and the air pressure in the gas collecting cavity 111 breaks through the pressure relief valve provided in the gas transmission channel, and the ejection mechanism 200 is ejected upward under the action of the gas.

[0032] Then, in Figure 6 Based on and combined with Figure 8 As shown, the structure of the ejection mechanism 200 is disclosed. The ejection mechanism 200 includes two side levers 210, an ejection plate 220 is fixedly connected between the two side levers 210, and a piston head 230 is fixedly connected to the bottom of the ejection plate 220 through a connecting rod. The piston head 230 is sleeved and matched with the piston cavity 112, and the casting mold plate 110 below the piston head 230 is provided with an air hole connected to the piston cavity 112. The air flow is divided into two streams after passing through the air transmission channel, one air flow is used to push the piston head 230 to move upward, and the other air flow flows out from the air hole.

[0033] Because the protruding rods 142 are symmetrically fixedly connected to both sides of the debris removing plate 140, when the debris removing plate 140 moves to the end, the lever 210 is located directly below the protruding rod 142. Here, under the action of the airflow, the lever 210 moves upward, and the lever 210 pushes the protruding rod 142 to make the protruding rod 142 rotate clockwise along the connecting axis between the debris removing plate 140 and the recovery plate 141. It should be noted that: during the rotation process, the lever 210 pushes the protruding rod 142 clockwise to an inclined state, so that the debris removing plate 140 can be tilted on the recovery plate 141. Since the lever 210 is in contact with the protruding rod 142, the lever 210 supports the protruding rod 142. During the rotation process, the protruding rod 142 slides on the lever 210, and the protruding rod 142 also slides on the lever 210, and the lever 210 always supports the protruding rod 142 during the sliding process.

[0034] During this process, the impurity removing plate 140 overcomes the elastic potential energy of the first arc springs 143 on both sides to rotate, and the impurity removing plate 140 moves upward along the end of the mold groove, and the protrusion on the impurity removing plate 140 limits the reverse sliding of the sodium salt, thereby pouring the sodium salt that has not been completely transferred above the protruding rod 142 into the recovery plate 141, avoiding the residual sodium salt from affecting the working environment and improving the purity of the recovered lead ingots.

[0035] At the same time, Figure 6 Based on and combined with Figure 7As shown, an exhaust hole 114 and an exhaust channel 113 connected to the air collecting cavity 111 are opened in the casting template 110 on one side of the air collecting cavity 111, the exhaust channel 113 is connected to the exhaust hole 114, and a valve assembly is arranged inside the exhaust hole 114, the valve assembly includes a partition 151, a steel rope 152 and a protrusion 150, the protrusion 150, the steel rope 152 and the partition 151 are connected in sequence, the partition 151 is used to block the exhaust hole 114, the protrusion 150 is located on the top side of the piston cavity 112, and the protrusion 150 is on the moving path of the piston head 230.

[0036] In this way, during the upward movement of the piston head 230, the piston head 230 pushes the protrusion 150 to move, so that the protrusion 150 pulls the partition 151 through the steel rope 152 to slowly open the exhaust hole 114. When the protrusion 150 rises to abut against the inner wall of the piston chamber 112, the exhaust hole 114 is in a state of not being fully opened.

[0037] It should be noted that: at the moment the exhaust hole 114 is opened, the gas in the gas collecting chamber 111 can no longer provide support for the counterweight plate 115, that is, the counterweight plate 115 moves downward under the action of gravity to discharge the air in the gas collecting chamber 111 into the exhaust channel 113.

[0038] Compared with the fully open exhaust hole 114, the cross-sectional area of ​​the exhaust hole 114 is small at this time, and the air flow velocity below the counterweight plate 115 is large. At the same time, under the gravity of the counterweight plate 115, when the counterweight plate 115 moves down to below the connection between the gas collecting cavity 111 and the gas transmission channel, the counterweight plate 115 pushes the air in the lower gas collecting cavity 111 to flow to the exhaust channel 113, and then uses the negative pressure generated by the air flow in the exhaust channel 113 to suck away the sodium salt in the recovery plate 141. The specific process is as follows: Preferably, combined Figure 2 , Figure 6 , Fig. 9 As shown, auxiliary boxes 160 cooperating with the recovery plate 141 are fixedly arranged on both sides of the casting plate 110 at the end of the casting groove, and a branch pipe 161 is connected to the bottom of the auxiliary box 160, and the branch pipe 161 is connected to the main pipe 162 at the end of the inclined state. One end of the main pipe 162 is connected to the exhaust channel 113, and the other end is provided with a collection box 102 for collecting sodium salt, and a contraction cone 163 for pressurized airflow is provided in the main pipe 162 near the exhaust channel 113.

[0039] After the airflow passes through the exhaust hole 114 and the exhaust channel 113, the airflow passes through the main pipe 162 and flows out from the end. Since the branch pipe 161 is connected to the main pipe 162, in order to prevent the airflow in the main pipe 162 from flowing back out of the branch pipe 161 when it is released instantly, a baffle 170 is rotatably connected to the inner wall of the branch pipe 161, and a second arc spring 171 is connected between the baffle 170 and the inner wall of the branch pipe 161. Under normal conditions, the second arc spring 171 is in a released state, and the baffle 170 limits the reverse flow of the airflow.

[0040] Therefore, the air flow flows in the main pipe 162, and the flow velocity increases after the air flow passes through the contraction cone 163, so that a negative pressure area is formed in the branch pipe 161. Under the action of pressure, the baffle 170 opens, and the branch pipe 161 is in a conducting state. The sodium salt on the recovery plate 141 slides into the main pipe 162 through the auxiliary box 160 and the branch pipe 161. Under the flow of air flow in the main pipe 162, the sodium salt is sprayed out from the end of the main pipe 162, thereby completing the transfer of the sodium salt and preventing the sodium salt from remaining on the recovery plate 141 and affecting the purity of the lead ingot.

[0041] When the casting plate 110 is turned over and in an inverted state, Figure 4 Under the elastic action of the middle reset spring 131, the reset spring 131 pushes the power rod 121 in the reverse direction to reset, and the impurity removal plate 140 and the recovery plate 141 move to the beginning of the mold groove, and the solidified lead ingot falls off from the mold groove to realize the recovery of the lead ingot. As the turning belt 100 rotates, the casting plate 110 gradually turns to an upright state, and then the lead liquid is injected again, and the cycle is repeated, thereby improving the recovery efficiency of the lead ingot, reducing the processing cost, and reducing environmental pollution.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention.
