Description

Technical Field

[0001] This invention belongs to the field of conveyor belt technology, and particularly relates to a large-angle belt conveyor for recycling waste lithium batteries. Background Technology

[0002] In the recycling and processing of waste lithium batteries, steeply inclined belt conveyors are crucial equipment connecting various processing steps and facilitating material transfer. Currently, most conveyor belts used for transporting waste lithium batteries on the market are conventional rubber conveyor belts, which have relatively limited functionality and can only meet basic material transport needs.

[0003] However, spent lithium batteries typically retain some electrolyte, which is mainly composed of carbonate organic solvents and lithium salts, exhibiting strong chemical corrosiveness. Even if existing conveyor belts are made of corrosion-resistant rubber, prolonged contact with the residual electrolyte will inevitably lead to aging phenomena such as rubber swelling, hardening, and embrittlement. These aging problems directly result in decreased elasticity and flexibility of the conveyor belt, leading to cracking, delamination, and other malfunctions. This severely impacts the normal service life and operational stability of the conveyor belt, increases equipment maintenance costs and operational interruption risks in spent lithium battery recycling, and fails to meet the efficient and stable production demands of the spent lithium battery recycling industry.

[0004] Therefore, it is necessary to invent a high-angle belt conveyor for recycling waste lithium batteries to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a steeply inclined belt conveyor for recycling waste lithium batteries, thereby solving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-angle belt conveyor for recycling waste lithium batteries, comprising: A conveyor belt is used to transport used lithium batteries, and the conveyor belt includes horizontal and inclined sections; Conveyor rollers are evenly distributed on the inner side of the conveyor belt to drive the conveyor belt to rotate. Side plates, the number of which is two, the two side plates are respectively connected to both ends of a plurality of conveying rollers, for mounting the conveying rollers; The material blocking device includes baffles, sealing strips, water absorption components, and pressing components. Multiple baffles are evenly distributed on the outer surface of the conveyor belt. Each baffle is hollow and has a mounting hole on one side. The sealing strip is detachably installed at the mounting hole. The water absorption component is located inside the baffle, and several liquid inlet holes are evenly provided on one side of the baffle in the forward direction. Two pressing components are symmetrically arranged at the front and rear sides of the horizontal section of the conveyor belt to squeeze the water absorption component.

[0007] Furthermore, the top of the inclined section of the conveyor belt is higher than the horizontal section, and a collection trough is provided at the bottom of the horizontal section.

[0008] Furthermore, the water-absorbing assembly includes a sponge, fixing strips, limiting rods, and a return spring. The sponge is movably disposed inside the baffle, and the thickness of the sponge matches the width of the inner side of the baffle. There are two fixing strips, which are respectively fixedly connected to the top and bottom of the sponge, and filter holes are evenly opened on the fixing strip away from the conveyor belt. There are two limiting rods, which are respectively vertically located at the front and rear sides of the sponge. The limiting rods are vertically slidably inserted between the two fixing strips, and the two ends of the limiting rods are respectively fixedly connected to the top and bottom inner walls of the baffle. The return spring is slidably sleeved on the limiting rods, and the two ends of the return spring are respectively fixedly connected to the two fixing strips. Several drainage holes are evenly arranged on the side of the baffle away from the conveyor belt.

[0009] Furthermore, the pressing assembly includes a pressing strip, a pressing rod, and a connecting plate. The pressing strip includes a horizontal section and an inclined section. The inclined section of the pressing strip is inclined in the same direction as the inclined section of the conveyor belt, and the inclined section of the pressing strip is closer to the inclined section of the conveyor belt than its horizontal section. There are two pressing rods, which are symmetrically fixedly connected to both ends of a fixed strip without filter holes. When the baffle is located at the bottom of the horizontal section of the conveyor belt, the top of the inclined section of the pressing strip is higher than the height of the pressing rod. Vertical strip holes are opened through the sealing strip and the side of the baffle, which are directly opposite the pressing rod. The pressing rod is inserted through the strip holes. The connecting plate is L-shaped and is fixedly connected between the top of the pressing strip and the side plate on the same side.

[0010] Furthermore, a buffer assembly is provided on the inner side of the horizontal section of the conveyor belt. The buffer assembly includes a buffer plate, telescopic rods, shock-absorbing springs, and rollers. The buffer plate is horizontally inserted into the inner side of the conveyor belt. There are multiple telescopic rods, which are uniformly and vertically fixedly connected to the bottom of the buffer plate, and the bottom end of the telescopic rod is fixedly connected to the adjacent side plate. The shock-absorbing spring is sleeved on the telescopic rod, and the two ends of the shock-absorbing spring are respectively fixedly connected to the surface of the telescopic rod near the two ends. There are multiple rollers, which are uniformly installed on the top of the buffer plate. The top of the roller always remains in contact with the top inner wall of the horizontal section of the conveyor belt, and the length direction of the roller is parallel to the length direction of the baffle.

[0011] Furthermore, the pressing strip can contact the pressing rod, and several strip-shaped protrusions are evenly distributed at the bottom end of the horizontal section of the pressing strip.

[0012] Furthermore, the inclined belt conveyor for recycling waste lithium batteries also includes a staircase installed on one side of the conveyor belt, and the staircase is parallel to the inclined section of the conveyor belt.

[0013] Furthermore, the side of the baffle near the liquid inlet is designed to be concave for collecting electrolyte.

[0014] Furthermore, two inclined guide strips are symmetrically fixedly connected to the side of the baffle near the conveyor belt, and the inclined guide strips are smoothly connected to the conveyor belt.

[0015] Furthermore, the height of the sponge is equal to half the height of the baffle, and the liquid inlet holes are distributed in the half-section of the baffle near the conveyor belt.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention achieves efficient absorption, squeezing out and centralized collection of residual electrolyte from waste lithium batteries by combining the water absorption component and the pressing component in the material blocking device. This avoids the electrolyte from adhering to the conveyor belt for a long time, significantly reduces the corrosive effect of the electrolyte on the belt, effectively delays belt aging, extends the service life of the conveyor belt, and reduces equipment maintenance costs. 2. This invention incorporates a buffer component. When waste lithium batteries are placed on the conveyor belt, as they fall onto the horizontal section of the belt, the pressure exerted by the batteries on the belt compresses the buffer plate downwards. This causes the buffer plate to move downwards and compress the telescopic rod and the shock-absorbing spring. As the shock-absorbing spring is compressed, the impact force of the waste lithium batteries on the conveyor belt is converted into the elastic potential energy of the spring. This effectively reduces the impact force of the waste lithium batteries on the conveyor belt, protects the conveyor belt, and extends its service life. 3. The present invention provides a strip-shaped protrusion at the bottom of the horizontal section of the pressing bar. When the pressing rod moves to the bottom of the horizontal section of the pressing bar, the sponge can complete the extrusion of electrolyte under the squeezing action of the fixed bar. At this time, as the pressing rod continues to move along the bottom of the horizontal section of the pressing bar, the strip-shaped protrusion at the bottom of the horizontal section of the pressing bar can contact the pressing rod, thereby generating vibration through the collision between the pressing rod and the pressing rod. As the pressing rod vibrates, the vibration can be transmitted to the baffle, so that some of the electrolyte attached to the bottom of the baffle can quickly drip into the collection tank under the action of vibration, avoiding electrolyte residue on the baffle.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides, for example Figures 1 to 8The diagram shows a steeply inclined conveyor belt for recycling waste lithium batteries, comprising: a conveyor belt 1, conveyor rollers 2, side plates 3, and a material-blocking device. The conveyor belt 1 is used to transport waste lithium batteries and includes a horizontal section and an inclined section. The conveyor rollers 2 are evenly arranged on the inner side of the conveyor belt 1 to drive its rotation. There are two side plates 3, which are respectively connected to both ends of multiple conveyor rollers 2 for mounting the rollers 2. The material-blocking device includes baffles 4, sealing strips 5, a water-absorbing component, and a pressing component. There are multiple baffles 4, which are evenly distributed. On the outer surface of the conveyor belt 1, the baffle 4 is hollow and has a mounting hole on one side. The sealing strip 5 is detachably installed at the mounting hole. The hollow design of the baffle 4 and the detachable sealing strip 5 facilitate the maintenance and replacement of the water absorption component. The water absorption component is located inside the baffle 4, and several liquid inlet holes 6 are evenly opened on one side of the baffle 4 in the forward direction. There are two pressing components, which are symmetrically arranged on the front and rear sides of the horizontal section of the conveyor belt 1 to squeeze the water absorption component. The side of the baffle 4 near the liquid inlet hole 6 is concave to collect the electrolyte. The water-absorbing assembly includes a sponge 8, fixing strips 9, limiting rods 10, and a return spring 11. The sponge 8 is movably disposed inside the baffle 4, and the thickness of the sponge 8 matches the width of the inner side of the baffle 4. There are two fixing strips 9, which are fixedly connected to the top and bottom of the sponge 8, respectively. Filter holes are evenly distributed on the fixing strip 9 furthest from the conveyor belt 1. There are two limiting rods 10, which are vertically located at the front and rear sides of the sponge 8, respectively. The limiting rods 10 slide vertically through and are inserted between the two fixing strips 9. Both ends are fixedly connected to the top and bottom inner walls of the baffle 4 respectively. The return spring 11 is slidably sleeved on the limit rod 10, and both ends of the return spring 11 are fixedly connected to two fixing strips 9 respectively. Several drainage holes are evenly arranged on the side of the baffle 4 away from the conveyor belt 1. The height of the sponge 8 is equal to half the height of the baffle 4, and the liquid inlet 6 is distributed in the half area of ​​the baffle 4 near the conveyor belt 1. Two inclined guide strips 21 are symmetrically fixedly connected on the side of the baffle 4 near the conveyor belt 1, and the inclined guide strips 21 are smoothly connected to the conveyor belt 1. With the water absorption component installed, when the waste lithium battery is transported, after the waste lithium battery is placed on the top of the horizontal section of the conveyor belt 1, as the conveyor roller 2 rotates, the waste lithium battery located on the top of the conveyor belt 1 can gradually move towards the inclined section of the conveyor belt 1 under the drive of the conveyor belt 1. During this process, the waste lithium battery gradually tilts upward. Due to the presence of the baffle 4, the baffle 4 can provide support for the waste lithium battery, thereby preventing the waste lithium battery from sliding down along the inclined section of the conveyor belt 1. During the process of conveyor belt 1 transporting waste lithium batteries, when the residual electrolyte on the surface of the waste lithium batteries drips onto conveyor belt 1, the electrolyte can flow along the top inclined surface of conveyor belt 1 to baffle 4 under the action of gravity. Then, guided by the inclined guide strip 21, the electrolyte can flow to the concave surface of baffle 4 and collect. Then, the collected electrolyte can enter the interior of baffle 4 through the liquid inlet 6, thereby contacting the sponge 8 on the inner side of baffle 4. The sponge 8 can then quickly absorb the electrolyte, thereby preventing the electrolyte from accumulating or flowing randomly on conveyor belt 1, preventing conveyor belt 1 from being corroded by electrolyte, effectively delaying belt aging, extending the service life of conveyor belt 1, and reducing equipment maintenance costs.

[0021] like Figures 3 to 8 As shown, the pressing assembly includes a pressing strip 12, a pressing rod 13, and a connecting plate 14. The pressing strip 12 includes a horizontal section and an inclined section. The inclined section of the pressing strip 12 is inclined in the same direction as the inclined section of the conveyor belt 1, and the inclined section of the pressing strip 12 is closer to the inclined section of the conveyor belt 1 than its horizontal section. There are two pressing rods 13, which are symmetrically fixedly connected to both ends of the fixed strip 9 without filter holes. When the baffle 4 is located at the bottom of the horizontal section of the conveyor belt 1, the top of the inclined section of the pressing strip 12 is higher than the height of the pressing rod 13. The sealing strip 5 and the side of the baffle 4 are both provided with vertical strip holes that are directly opposite the pressing rod 13, and the pressing rod 13 is inserted through the strip holes. The connecting plate 14 is L-shaped and is fixedly connected between the top of the pressing strip 12 and the side plate 3 on the same side. The top of the inclined section of the conveyor belt 1 is higher than the horizontal section, and a collection groove 7 is provided at the bottom of the horizontal section. With the addition of a pressing component, as the conveyor belt 1 rotates, when the baffle 4 moves to the bottom of the conveyor belt 1, the sponge 8 located inside the baffle 4 can move away from the conveyor belt 1 along the limiting rod 10 under gravity. This allows the fixing strip 9 with filter holes to remain in contact with the inner wall of the baffle 4 with drainage holes. At this time, the liquid inlet 6 can remain offset from the sponge 8. As the conveyor belt 1 continues to rotate, when the baffle 4 containing the absorbent sponge 8 moves to the bottom of the horizontal section with the conveyor belt 1, the sides of the baffle 4... The pressure bar 13 gradually comes into contact with the pressure bar 12 of the pressing assembly. Due to the design of the inclined section of the pressure bar 12, as the conveyor belt 1 continues to move, the pressure of the pressure bar 12 on the pressure bar 13 gradually increases. The pressure bar 13 moves downward along the strip hole, causing the fixed bar 9 at the top to squeeze the sponge 8. During this process, the return spring 11 is gradually compressed. When the sponge 8 is squeezed, the electrolyte absorbed inside it can be squeezed out of the baffle 4 through the filter hole and drain hole, and finally drip into the collection tank 7 below, completing the collection and treatment of the electrolyte. Subsequently, as the conveyor belt 1 continues to operate, when the pressure bar 13 is completely separated from the pressing bar 12, as the return spring 11 gradually extends, the two fixing bars 9 can move away from each other, thereby pulling the sponge 8 to stretch and recover. At this time, the sponge 8, after being squeezed, regains its good water absorption effect, thus ensuring that the sponge 8 can absorb the residual electrolyte in a timely and effective manner during the subsequent transportation of waste lithium batteries.

[0022] like Figure 3 and Figure 4 As shown, a buffer assembly is provided on the inner side of the horizontal section of the conveyor belt 1. The buffer assembly includes a buffer plate 15, telescopic rods 16, shock-absorbing springs 17, and rollers 18. The buffer plate 15 is horizontally inserted into the inner side of the conveyor belt 1. There are multiple telescopic rods 16, which are uniformly and vertically fixedly connected to the bottom of the buffer plate 15. The bottom end of the telescopic rod 16 is fixedly connected to the adjacent side plate 3. The shock-absorbing spring 17 is sleeved on the telescopic rod 16, and the two ends of the shock-absorbing spring 17 are fixedly connected to the surfaces of the telescopic rod 16 near the two ends. There are multiple rollers 18, which are uniformly installed on the top of the buffer plate 15. The top of the rollers 18 always stays in contact with the top inner wall of the horizontal section of the conveyor belt 1, and the length direction of the rollers 18 is parallel to the length direction of the baffle 4. By incorporating a buffer assembly, when waste lithium batteries are placed onto the conveyor belt 1, the pressure exerted by the batteries on the belt as they fall onto the horizontal section of the belt compresses the buffer plate 15. This causes the buffer plate 15 to move downwards and compress the telescopic rod 16 and the shock-absorbing spring 17. As the shock-absorbing spring 17 is compressed, the impact force of the waste lithium batteries on the conveyor belt 1 is converted into the elastic potential energy of the spring 17, effectively reducing the impact force of the waste lithium batteries on the conveyor belt 1, protecting the conveyor belt 1, and extending its service life. Simultaneously, during the operation of the conveyor belt 1, the roller 18 can roll with the conveyor belt 1 under the action of friction, reducing frictional loss between the buffer plate 15 and the belt.

[0023] like Figure 6 As shown, the pressing strip 12 can contact the pressing rod 13, and several strip-shaped protrusions 19 are evenly distributed at the bottom end of the horizontal section of the pressing strip 12. By providing a strip-shaped protrusion 19 at the bottom of the horizontal section of the pressing bar 12, when the pressing rod 13 moves to the bottom position of the horizontal section of the pressing bar 12, the sponge 8 can complete the extrusion of electrolyte under the squeezing action of the fixing strip 9. At this time, as the pressing rod 13 continues to move along the bottom of the horizontal section of the pressing bar 12, the strip-shaped protrusion 19 at the bottom of the horizontal section of the pressing bar 12 can contact the pressing rod 13, thereby generating vibration through the collision with the pressing rod 13. As the pressing rod 13 vibrates, the vibration can be transmitted to the baffle 4, so that some of the electrolyte adhering to the bottom of the baffle 4 can quickly drip into the collection tank 7 under the action of vibration, avoiding electrolyte residue on the baffle 4.

[0024] like Figure 1 and Figure 2 As shown, the inclined belt conveyor for recycling waste lithium batteries also includes a staircase 20 installed on one side of the conveyor belt 1, and the staircase 20 is parallel to the inclined section of the conveyor belt 1. A staircase 20 is installed on one side of the conveyor belt 1. During the transportation of lithium batteries, workers can conveniently reach the top of the inclined section of the conveyor belt 1 or other height positions via the staircase 20, which facilitates the inspection, maintenance or observation of the material conveying status of the equipment, and improves the convenience and safety of equipment operation.
