Description

Technical Field

[0001] The invention relates to the technical field of waste collection, and in particular to a waste collection device for recycling lithium batteries. Background Art

[0002] Used batteries contain a large amount of heavy metals and electrolyte solutions such as waste acid and waste alkali. If discarded at will, the corrupted batteries will destroy our water sources and erode the crops and land on which we depend for survival. Our living environment will face a huge threat. Therefore, it is necessary for us to recycle and reuse used batteries. On the one hand, it can prevent environmental pollution, and on the other hand, the useful components can be reused to save resources. The existing lithium battery recycling waste collection device has a simple structure, and the lithium battery trash can is difficult to take out, which is quite inconvenient for the recycling personnel to recycle, and the users are quite annoyed by this.

[0003] For example, the Chinese patent with the publication number "CN212557790U" discloses "a lithium battery recycling waste collection device", whose main structure includes a floor plate, an outer shell box is fixedly installed on the top of the floor plate, an inner cylinder with one end penetrating and extending into the inner shell box is inserted on the top of the outer shell box, and a pad is fixedly installed on the bottom of the inner cylinder. The lithium battery recycling waste collection device is provided with side panels, limit rods, blocks, covers, delivery holes and feeding holes. Users can put waste batteries into the inner cylinder through the delivery holes and feeding holes. When the recycling personnel collect the batteries in the inner cylinder, they carry the cover, which drives the inner cylinder to separate from the outer shell box, and the baffle slides down to cover the feeding hole. After taking out, the cover is rotated to separate from the inner cylinder, and the user pours out the waste batteries in the inner cylinder. In this way, the device is convenient for taking out batteries and is tightly sealed. Even if the inner cylinder is corroded and perforated, the lithium battery will not leak into the environment, but will be stored in the outer shell box.

[0004] From the above description, it can be known that when the above-mentioned lithium battery recycling waste collection device is delivering lithium batteries, it is necessary to set side panels, limit rods, blocks, covers, delivery holes and feeding holes. The user delivers the waste batteries into the inner cylinder through the delivery holes and feeding holes. During the delivery process, since the delivery holes and feeding holes are in an open state, the contaminated gas in the inner cylinder will leak out along the open parts, causing the external environment to be polluted.

[0005] For another example, the Chinese patent with the publication number "CN218731217U" discloses "a centrifugal lithium battery electrode waste collection device", whose main structure includes a shell, a fan and a guide member all arranged in the shell, a discharge port is arranged at the bottom of the shell, a feed port and an air outlet are arranged on the side walls of the shell respectively, the air outlet is located above the feed port, the guide member is located between the feed port and the air outlet, and the guide member is provided with an air duct, which connects the feed port and the air outlet; the fan is used to drive air to flow to the air outlet through the air duct so as to generate centrifugal force inside the shell. The above centrifugal lithium battery electrode waste collection device uses a cyclonic centrifugal method to discharge lithium battery waste, so that the lithium battery waste rotates and falls, avoiding the negative pressure from sucking back the lithium battery waste.

[0006] However, in actual operation, the feed port of the centrifugal lithium battery electrode waste collection device is in an open state, which will cause environmental pollution to the waste lithium batteries in the storage area due to air flow. In other words, the sealing ability of the lithium batteries will be reduced before and after they are put into storage, and the lithium batteries in storage will still cause pollution to the external environment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1A lithium battery recycling waste collection device comprises a vertical tank body 1 with a lithium battery storage cavity 2 arranged therein, a concave gathering area 9 located at the bottom of the lithium battery storage cavity 2, a lithium battery discharge port 3 arranged at the bottom center of the vertical tank body 1 and connected to the bottom port of the concave gathering area 9, a valve body 4 that can be pulled out and inserted into the bottom end of the lithium battery discharge port 3, a gas compression cavity 6 arranged inside the vertical tank body 1 and located directly above the lithium battery storage cavity 2, a delivery channel 7 that longitudinally penetrates the gas compression cavity 6 and is connected to the lithium battery storage cavity 2 at the bottom, a lithium battery delivery slot 8 arranged at the top of the delivery channel 7 and having an opening at the top, and a gas channel 10 arranged on the side of the vertical tank body 1 and connected to the gas compression cavity 6. By putting the waste lithium batteries into the lithium battery delivery slot 8, the lithium batteries can fall into the lithium battery storage cavity 2 through the delivery channel 7 under the action of gravity, so as to realize the storage of the lithium batteries. When the waste lithium batteries need to be recycled, the valve body 4 can be opened, and the lithium batteries can be discharged downward under the action of gravity.

[0034] In order to realize the controllable opening and closing function of the lithium battery storage chamber 2 and the external environment, please refer to Figure 1 , Figure 2 and Figure 3 , it is necessary to set up a centrifugal rotating structure 13, which is installed inside the gas compression cavity 6 through a mechanical sealing structure, and is provided with a central area communicating with the delivery channel 7, and an inner rubber bag 134 that generates a closed state of the central area after the periphery is subjected to gas pressure, and an outer rubber bag 135 that is located outside the inner rubber bag 134 and expands toward the periphery after rotation. In the initial state, it is necessary to inject gas into the gas limiting cavity 137 through an air pressure pump, and the gas pressure meets the static state, so that the inner rubber bag 134 is deformed toward the center to form an extrusion blockage phenomenon, and the outer rubber bag 135 is in a longitudinal straightening phenomenon. Therefore, in the non-rotating state, the lithium battery discharge hole 136 is in a closed state. state, thereby effectively preventing the polluted gas in the lithium battery storage chamber from contacting the gas in the external environment to ensure its environmental protection. When the outer rubber bag 135 rotates to form sufficient centrifugal force, and when the centrifugal force is greater than the deformation strength of the outer rubber bag 135, the outer rubber bag 135 will expand toward the surroundings. At this time, the space of the gas limiting chamber 137 becomes larger, and the air pressure value inside the gas limiting chamber 137 decreases, and the inner rubber bag 134 can reset under the action of its own reset elasticity, so that the lithium battery discharge hole 136 is in an open state, and the lithium battery can be dropped normally, thereby realizing the controllable opening and closing function of the lithium battery storage chamber 2 and the external environment.

In order to have the closing ability, it is necessary to make The elastic strength of the inner rubber bag 134 is smaller than that of the outer rubber bag 135, and after the gas is injected into the gas limiting cavity 137, the pressure of the gas meets the condition that the inner rubber bag 134 is deformed toward the center to form an extrusion blockage phenomenon, while the outer rubber bag 135 is in a longitudinal straightening phenomenon. The inner circumferential surface of the outer rubber bag 135 is provided with a plurality of annular protrusion structures 138 arranged in an upper and lower manner, a valve 139 for injecting gas into the gas limiting cavity 137 is installed inside the top rotating plate 132, annular mounting grooves 1310 installed in the gas compression cavity 6 through a mechanical sealing structure are provided on the circumferential surfaces of the bottom rotating plate 131 and the top rotating plate 132, and the lithium battery discharge hole 136 located in the top rotating plate 132 is seamlessly connected to the delivery channel 7.

[0036] In order to reduce the pollution of the gas inside the lithium battery storage chamber 2 to the external environment during the process of placing the lithium battery, please refer to Figure 1 , Figure 4 and Figure 5, it is necessary to set up a ball valve type gas one-way flow structure 14 and a semi-annular gas flow hole 11, wherein the ball valve type gas one-way flow structure 14 is fixedly installed inside the gas channel 10, and is provided with a free ball valve 145 inside thereof, which is in an open state when the gas enters the gas compression cavity 6 from the outside and in a blocked state when the gas inside the gas compression cavity 6 flows to the outside, and the semi-annular gas flow hole 11 is arranged inside the vertical tank body 1 and connected to the top of the gas compression cavity 6, and the circumferential side surface of the semi-annular gas flow hole 11 is connected to the circumferential surface of the lithium battery delivery slot 8 through the oblique exhaust groove 12. In order to form a sufficient "gas curtain" range, it is necessary to make the arc length of the semi-annular gas flow hole 11 half of the structural circumference of the gas compression cavity 6 at the connection intersection, and the oblique exhaust groove 12 is oblique Pointing upward to the lithium battery delivery slot 8, when the outer rubber bag 135 expands toward the periphery during the rotation process, the space inside the gas compression cavity 6 will be reduced, and the free ball valve 145 is blocked at the end of the air inlet 143 under the action of gravity, resulting in an increase in the air pressure value inside the gas compression cavity 6, and the compressed gas will be sprayed to the inside of the lithium battery delivery slot 8 through the oblique exhaust groove 12, and form an "air curtain" phenomenon inside the lithium battery delivery slot 8, which can make the delivery channel in an open state when the waste lithium batteries are delivered, and when the delivery channel is in an open state, it can produce an air curtain partition effect on the delivery channel opening, thereby reducing the flow of external gas in the equipment without affecting the delivery of lithium batteries, so as to reduce the degree of pollution of the external environment during the delivery process and improve the environmental protection of the equipment.

[0037] It should be noted that the time of placing a single battery needs to be controlled within the time range required for the gas compression cavity 6 to be completely discharged to the outside, otherwise the degree of internal gas leakage will increase.

[0038] For the specific structure of the ball valve type gas one-way flow structure 14, please refer to Figure 4 and Figure 5, comprising a rectangular hollow block 141 which is sealed on the side and placed inside the vertical tank body 1, wherein a spherical cavity 142 is arranged at the center of the rectangular hollow block 141, an air inlet 143 with a smaller structural radius than the spherical cavity 142 is arranged at the bottom center of the spherical cavity 142, an exhaust hole 144 with a smaller structural radius than the spherical cavity 142 is arranged at the bottom center of the spherical cavity 142, a free ball valve 145 is placed inside the spherical cavity 142, one end of the air inlet 143 is connected to the bottom center structure of the spherical cavity 142, and the other end is connected to the rectangular hollow block 141.

In order to form a one-way flow control effect of the gas, it is necessary to make the structural radius of the air inlet hole 143 and the exhaust hole 144 smaller than the structural radius of the free ball valve 145, and the structural radius of the free ball valve 145 is smaller than the structural radius of the spherical cavity 142.

[0039] To achieve the kinetic energy generation required for the drive, see Figure 1 , Figure 6 and Figure 7 , it is necessary to set up a motor drive structure 15, which is fixedly installed on the side of the vertical tank body 1, and is provided with a drive motor 152 for generating a power source and a first bevel gear 155 and a second bevel gear 156 for driving the centrifugal rotating structure 13 to rotate. When the drive motor 152 is started, the rotor 153 will drive the first bevel gear 155 and the second bevel gear 156 to rotate, thereby driving the outer rubber bag 135 to rotate, generating the necessary movement of the centrifuge, and during the rotation process, the rotation of the eccentric rotating column 158 will cause the vertical tank body 1 to vibrate in the longitudinal direction due to gravity. The power source of the device comes from a drive motor 152, thereby effectively improving the utilization rate of kinetic energy and reducing the cost of use.

[0040] For the specific structure of the motor drive structure 15, please refer to Figure 6 and Figure 7, comprising a motor fixing housing 151 and a cylindrical fixing frame 154 fixedly mounted horizontally on the side of the vertical tank body 1, a driving motor 152 is mounted inside the motor fixing housing 151, a rotor 153 of the driving motor 152 passes through the side structure of the vertical tank body 1, a first bevel gear 155 at a vertical angle is fixedly mounted on one end of the rotor 153 located inside the lithium battery storage chamber 2, the top end of the cylindrical fixing frame 154 is fixedly mounted on the bottom end surface of the bottom rotating plate 131, and a second bevel gear 156 in a horizontal state is fixedly mounted on the bottom end of the cylindrical fixing frame 154, the cylindrical A lithium battery dropping hole 157 with an opening at the bottom and a top connected to the lithium battery discharge hole 136 is provided in the center of the bevel fixing frame 154 and the second bevel gear 156. The tooth structures in the second bevel gear 156 and the first bevel gear 155 are meshed with each other. The rotor 153 is fixedly mounted with an eccentric rotating column 158 on the shaft located inside the lithium battery storage chamber 2. A rotor fixing hole 159 is provided in the center of the eccentric rotating column 158. In order to produce an eccentric effect, it is necessary to make the mass of the eccentric rotating column 158 on one side of the rotor fixing hole 159 smaller than its mass on the other side of the rotor fixing hole 159.

[0041] In order to increase the vibration of the vertical tank 1 during the feeding process, please refer to Figure 1 and Figure 8 , it is necessary to set up an elastic support structure 16, which includes a bottom support base plate 161 located directly below the vertical tank body 1 and an annular fixing plate 162 fixedly installed at the bottom end of the vertical tank body 1, and a sleeve hole 163 is arranged at the center of the annular fixing plate 162, which is sleeved on the periphery of the lithium battery discharge port 3. Three spiral springs 164 arranged in a circular array are installed between the upper surface of the bottom support base plate 161 and the lower surface of the annular fixing plate 162. The elastic strength of the three spiral springs 164 is sufficient to make the vertical tank body 1 in a vertical position when the drive motor 152 is not started. When the vertical tank body 1 vibrates under the action of the eccentric rotating column 158, the spiral spring 164 will amplify the vibration, thereby increasing the shaking degree of the vertical tank body 1. The shaking can cause the lithium battery being put in to fall quickly, thereby accelerating the efficiency of lithium battery feeding.

[0042] During use, when it is necessary to place used batteries, start the drive motor 152. When the lithium battery discharge hole 136 is in an open state, quickly place the used lithium battery sleeve into the lithium battery placement slot 8. Under the action of gravity, the lithium battery will fall into the lithium battery storage chamber 2 to achieve storage. When no gas is discharged outward through the oblique exhaust groove 12, turn off the drive motor 152 in time until the lithium battery discharge hole 136 is completely closed before the next lithium battery placement can be carried out.
