Description

Technical Field

[0001] The utility model relates to the technical field of recycling and treatment of waste lead-acid batteries, in particular to a device for extracting grid plates from lead-acid battery scraps. Background Art

[0002] Lead-acid batteries have relatively low production costs and are safe and reliable to use, and are widely used in various industries, which also leads to a large number of waste lead-acid batteries being generated every year. With the increasing demand for resources, in the production process of lead, recycling and regenerating lead from waste lead-acid batteries has more environmental protection and resource development advantages compared with traditional direct mining and smelting of ore lead.

[0003] The patent document with the application number CN200910010992.5 discloses a method for recycling lead oxide from waste lead-acid batteries. This method includes three parts: pretreatment, lead oxide synthesis, and by-product recovery. The specific pretreatment in this method is as follows: 1. After the battery is inverted to drain the acid, the upper cover is cut off by a cutting machine and the plates are poured out. After the plates are washed with acid, they are sent to a crusher. After crushing, they are screened to obtain grid plates and fillers (including lead mud); 2. The grid plates are directly melted into finished alloy ingots. After the fillers are finely ground to 60 meshes in a ball mill, they enter the lead oxide recovery process. When separating the grid plates and fillers of the scraps, only screening is used for separation. However, the fillers adhered to the grid plates cannot be effectively removed.

[0004] The patent document with the application number CN202322203461.6 discloses a device for extracting grid plates from lead-acid battery scraps. When this device works, it supports the bearing plate, and then pours the scraps into the feed hopper. During the operation of extracting the grid plates, the scraps fall from the discharge port and contact the top of the conveyor belt. Start the first motor, and the output end of the first motor drives the second pulley to rotate. The second pulley drives the first pulley to rotate through a belt, and the first pulley drives the conveying roller to rotate. Driven by the conveying roller, the conveyor belt starts to operate and drives the scraps to move. Then the scraps are conveyed from the end of the conveyor belt and contact the top surface of the sieve plate. At this time, start the second motor, and the output end of the second motor drives the threaded rod to rotate. Under the threaded rotation of the threaded rod, the moving frame moves horizontally. During the movement, the scraps fall into the aggregate bin through the sieve holes in the sieve plate, while the grid plates remain on the top surface of the sieve plate. Until the sieve plate is located above the collection box, the drive motor can be started. Start the drive motor, and the output end of the drive motor drives the second bevel gear to rotate. The second bevel gear drives the first bevel gear to rotate, the first bevel gear drives the support shaft to rotate, and the support shaft drives the sieve plate to rotate, so that the grid plates on the sieve plate fall into the collection box, thus completing the extraction operation of the grid plates. When separating the grid plates and fillers of the scraps, only screening is used for separation. However, the fillers adhered to the grid plates cannot be effectively removed. Summary of the Utility Model

[0005] The technical problem to be solved by the present utility model is a device for extracting grids from lead - acid battery scraps, which can extrude and knead the extracted grids, remove the fillers adhered to the grids, and improve the separation effect between the grids and the fillers.

[0006] To achieve the above - mentioned purpose, the technical solution provided by the present utility model is as follows:

[0007] A device for extracting grids from lead - acid battery scraps includes a front vibrating screen and a rear vibrating screen. An extrusion and kneading device is arranged between the front vibrating screen and the rear vibrating screen. The grids discharged from the front vibrating screen enter the extrusion and kneading device. After being extruded and kneaded by the extrusion and kneading device, the grids and the fillers falling off the grids fall into the rear vibrating screen, and the grids and fillers entering the rear vibrating screen are separated again.

[0008] The extrusion and kneading device includes a material guiding groove. A connecting frame is slidably arranged in the material guiding groove along the length direction of the material guiding groove. The connecting frame is connected with a driving component fixed in the material guiding groove. The connecting frame is connected with a pressing plate through a plurality of pressing cylinders. The axial direction of the pressing cylinders is perpendicular to the length direction of the material guiding groove. The pressing plate includes a pressing part and an inclined part. The inclined part is close to the front vibrating screen. The length direction of the pressing part of the pressing plate is parallel to the length direction of the material guiding groove. A plurality of rows of intercepting components are arranged at the lower end of the pressing part of the pressing plate. The intercepting components include a plurality of intercepting units. The intercepting units are elastically slidably connected with the pressing part of the pressing plate. The intercepting units of adjacent two rows of intercepting components are arranged in a staggered manner, and the intercepting units can intercept the grids entering the material guiding groove.

[0009] Specifically, one end of the material guiding groove close to the front vibrating screen is inclined upward, and the end of the material guiding groove close to the front vibrating screen is fixedly connected with the front vibrating screen.

[0010] Specifically, the connecting frame includes a plurality of fixed rods fixed in the material guiding groove. A plurality of sliding rods all penetrate through the plurality of fixed rods. The plurality of sliding rods are parallel to each other. The length direction of the sliding rods is parallel to the length direction of the material guiding groove. A plurality of pressing cylinders are fixed at the lower ends of the sliding rods.

[0011] Specifically, the driving component includes a connecting plate fixedly connected with the plurality of sliding rods. The connecting plate is perpendicular to the sliding rods. A reciprocating cylinder is fixed on the connecting plate. A fixing plate is fixed on the reciprocating cylinder, and the fixing plate is fixed in the material guiding groove.

[0012] Specifically, anti - slip patterns are processed on both the lower end of the pressing part of the pressing plate and the inner wall of the material guiding groove opposite to the lower end of the pressing part of the pressing plate.

[0013] Specifically, the interception unit includes a push rod. The axial direction of the push rod is perpendicular to the length direction of the material guiding groove. The upper end of the push rod is slidably inserted into the groove of the pressing part of the pressing plate. The upper end of the push rod is connected to the pressing part of the pressing plate by a spring. A universal ball is installed at the lower end of the push rod, and the universal ball is in rolling contact with the material guiding groove.

[0014] 1. The extrusion and kneading device can extrude and knead the grid plates discharged from the front vibrating screen, so that the fillers remaining on the grid plates fall off, and the separation effect of the grid plates and the fillers can be improved.

[0015] 2. After the grid plates discharged from the front vibrating screen enter the material guiding groove, they can be intercepted by multiple interception units between the pressing plate and the material guiding groove, which is convenient for the pressing plate to extrude and knead the grid plates in the material guiding groove.

[0016] 3. The material guiding groove is fixedly connected to the front vibrating screen. When the front vibrating screen works, the material guiding groove can vibrate, which can make the grid plates entering between the pressing plate and the material guiding groove more evenly dispersed and intercepted by the interception units. If the grid plates are gathered together, after the pressing plate extrudes the gathered grid plates, the fillers inside the agglomerated grid plates are not convenient to be discharged. The multiple interception units intercept the grid plates dispersedly, which can avoid the above problems and improve the separation efficiency of the fillers and the grid plates after the grid plates are extruded and kneaded.

[0017] 4. The pressing plate is provided with an inclined part, which can facilitate the grid plates to enter between the pressing plate and the material guiding groove.

[0018] 5. When the pressing plate extrudes the grid plates, the interception unit can retract into the groove of the pressing plate and will not affect the pressing plate to extrude the grid plates in the material guiding groove. Description of the Drawings

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0039] Embodiment 1: Refer to Figures 1-5 As shown, a grid plate extraction device in lead-acid battery scraps includes a front vibrating screen 1 and a rear vibrating screen 12. An extrusion and kneading device is arranged between the front vibrating screen 1 and the rear vibrating screen 12. The grid plates discharged from the front vibrating screen 1 enter the extrusion and kneading device. After being squeezed and kneaded by the extrusion and kneading device, the grid plates and the fillers falling from the grid plates fall into the rear vibrating screen 12, and the grid plates and fillers entering the rear vibrating screen 12 are separated again.

[0040] The scraps are screened in the front vibrating screen 1. The fillers are discharged from the lower end of the front vibrating screen 1, and the grid plates are discharged from the screen mesh of the front vibrating screen 1 and enter the guide groove 2.

[0041] One end of the guide groove 2 close to the front vibrating screen 1 is inclined upward. The grid plates in the guide groove 2 can slide towards the rear vibrating screen 12.

[0042] The extrusion and kneading device includes a guide groove 2. A connecting frame is slidably arranged in the guide groove 2 along the length direction of the guide groove 2. The connecting frame is connected to a driving component fixed in the guide groove 2. The connecting frame is connected to a pressing plate 3 through a plurality of extrusion cylinders 8. The axial direction of the extrusion cylinder 8 is perpendicular to the length direction of the guide groove 2.

[0043] Specifically, the connecting frame includes a plurality of fixing rods 4 fixed in the material guiding groove 2. A plurality of sliding rods 5 penetrate through the plurality of fixing rods 4. The plurality of sliding rods 5 are parallel to each other. The length direction of the sliding rods 5 is parallel to the length direction of the material guiding groove 2. A plurality of extrusion cylinders 8 are fixed at the lower ends of the sliding rods 5.

[0044] The driving assembly includes a connecting plate 6 fixedly connected to the plurality of sliding rods 5. The connecting plate 6 is perpendicular to the sliding rods 5. Reciprocating cylinders 7 are fixed on the connecting plate 6. Fixing plates 13 are fixed on the reciprocating cylinders 7. The fixing plates 13 are fixed in the material guiding groove 2.

[0045] When the reciprocating cylinder 7 is started, the reciprocating cylinder 7 can drive the sliding rods 5, the connecting plate 6, the extrusion cylinders 8 and the pressing plate 3 to move along the length direction of the material guiding groove 2 in the material guiding groove 2. After the extrusion cylinder 8 is started, the pressing plate 3 can extrude the grid plate between it and the material guiding groove 2.

[0046] The pressing plate 3 includes an extrusion part and an inclined part. The inclined part is close to the front vibrating screen 1. One end of the inclined part of the pressing plate 3 close to the front vibrating screen 1 inclines upward. By providing the inclined part, the inclined part can facilitate the grid plate to enter between the extrusion part of the pressing plate 3 and the material guiding groove 2.

[0047] The length direction of the extrusion part of the pressing plate 3 is parallel to the length direction of the material guiding groove 2. Anti-slip lines are processed on both the lower end of the extrusion part of the pressing plate 3 and the inner wall of the material guiding groove 2 opposite to the lower end of the extrusion part of the pressing plate 3. By providing anti-slip lines on the pressing plate 3 and the material guiding groove 2, the separation efficiency of the filler on the grid plate can be improved when the grid plate is extruded and rubbed.

[0048] A plurality of rows of intercepting components are arranged at the lower end of the extrusion part of the pressing plate 3. The intercepting component includes a plurality of intercepting units. The intercepting units are elastically slidably connected to the extrusion part of the pressing plate 3. The intercepting units of adjacent two rows of intercepting components are arranged in a staggered manner. The intercepting units can intercept the grid plate entering the material guiding groove 2.

[0049] The intercepting unit includes a top rod 9. The axial direction of the top rod 9 is perpendicular to the length direction of the material guiding groove 2. The upper end of the top rod 9 is slidably inserted into the groove of the extrusion part of the pressing plate 3. The upper end of the top rod 9 is connected to the extrusion part of the pressing plate 3 by a spring 11. A universal ball 10 is installed at the lower end of the top rod 9. The universal ball 10 is in rolling contact with the material guiding groove 2.

[0050] After the grid plate enters between the pressing plate 3 and the material guiding groove 2, a plurality of intercepting units can disperse and intercept the grid plate between the pressing plate 3 and the material guiding groove 2.

[0051] During operation, the crushed materials are screened in the front vibrating screen 1. The filler is discharged from the lower end of the front vibrating screen 1. The grid plate enters the material guiding groove 2 after being discharged from the screen mesh of the front vibrating screen 1. Since the material guiding groove 2 is inclined, the grid plate entering the material guiding groove 2 can move towards the rear vibrating screen 12.

[0052] After the grid plate enters between the extrusion part of the pressing plate 3 and the material guiding groove 2, it can be dispersed and intercepted by a plurality of ejector rods 9. Then, the extrusion cylinder 8 is started, so that the extrusion part of the pressing plate 3 extrudes the grid plate in the material guiding groove 2. When the extrusion part of the pressing plate 3 extrudes the grid plate in the material guiding groove 2, the ejector rods 9 move into the grooves of the pressing plate 3. At the same time, the spring 11 is extruded. After the extrusion part of the pressing plate 3 extrudes the grid plate in the material guiding groove 2, the reciprocating cylinder 7 is started, and the reciprocating cylinder 7 drives the pressing plate 3 to reciprocate along the length direction of the material guiding groove 2 in the material guiding groove 2. The extrusion part of the pressing plate 3 can extrude and knead the grid plate, so that the residual filler on the grid plate can fall off.

[0053] During the reciprocating movement of the pressing plate 3 in the material guiding groove 2, the universal balls 10 on the ejector rods 9 are in rolling contact with the material guiding groove 2, which can prevent the material guiding groove 2 from being scratched.

[0054] After the extrusion part of the pressing plate 3 extrudes and kneads the grid plate, the extrusion cylinder 8 is started to make the pressing plate 3 move upward. When the universal balls 10 are separated from the material guiding groove 2, the ejector rods 9 lose the interception of the grid plate, and the extruded and kneaded grid plate slides from the material guiding groove 2 into the rear vibrating screen 12.

[0055] The extruded and kneaded grid plate and the filler falling from the grid plate fall into the rear vibrating screen 12, and the grid plate and the filler entering the rear vibrating screen 12 are separated again.

[0056] Embodiment 2: On the basis of Embodiment 1, as shown in Figure 1 one end of the material guiding groove 2 close to the front vibrating screen 1 is fixedly connected to the front vibrating screen 1.

[0057] Since the material guiding groove 2 is fixedly connected to the front vibrating screen 1, when the front vibrating screen 1 works, it can make the material guiding groove 2 vibrate, so that the grid plates entering between the pressing plate 3 and the material guiding groove 2 can be dispersed more evenly and intercepted by the interception unit. If the grid plates are gathered together, after the pressing plate 3 extrudes and kneads the gathered grid plates, it is inconvenient for the filler inside the agglomerated grid plates to be discharged. The plurality of interception units disperse and intercept the grid plates, which can avoid the occurrence of the above problems and improve the separation efficiency of the filler and the grid plates after the grid plates are extruded and kneaded.

[0058] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
