Description

Technical Field

[0001] The invention relates to the field of polyolefin diaphragm recycling, and in particular to large-scale recycling equipment for waste polyolefin diaphragm materials. Background Art

[0002] This year, with the rise of the lithium battery industry, the output of polyolefin diaphragms, one of its key components, has also continued to increase. During its production process, due to differences in customer demand and defects that do not meet quality requirements, the output of waste is inevitable. If these wastes are not properly handled, they will become waste, which will not only cause a waste of raw materials, but also raise the unit price of the diaphragm;

[0003] Now the waste diaphragms are recycled on the market. In the current recycling device, the first step is to clean the waste gas diaphragm. In the traditional cleaning operation, the diaphragm is simply placed in water and stirred. The cleaning effect achieved by this single cleaning method is poor, and the cleaning efficiency needs to be improved. In addition, after the cleaning is completed, more water will adhere to it. If you wait for it to drain automatically, it will take a long time, which will obviously slow down the overall processing process. Therefore, it is necessary to consider how to solve this problem. Summary of the invention

[0007] Preferably, the interior of the cleaning tank is connected to the outside through a drain port, and a U-shaped support plate is fixedly connected to the inner bottom of the cleaning tank.

[0008] Preferably, the lifting mechanism includes a rectangular bar fixedly connected to the upper end of the shell, a sliding groove is opened on the right side of the rectangular bar, a threaded rod is rotatably connected between the upper and lower inner walls of the sliding groove, a slider is threadedly connected on the threaded rod, a connecting plate is fixedly connected to the right side of the slider, and the right side of the connecting plate is fixedly connected to the L-shaped plate.

[0009] Preferably, a first motor is installed at the upper end of the rectangular bar, and an output shaft of the first motor extends into the slide groove and is fixedly connected to the upper end of the threaded rod.

[0010] Preferably, the sliding block is slidably connected to the inner wall of the sliding groove, and the first motor is a servo motor capable of changing the rotation direction.

[0011] Preferably, the upper end of the rotating tube passes through the horizontal part of the L-shaped plate, a mounting frame is installed on the upper end of the horizontal part of the L-shaped plate, a second motor is installed on the mounting frame, and pulleys are installed on the output shaft of the second motor and the rotating tube, and the two pulleys are connected by a transmission belt.

[0012] Preferably, the auxiliary mechanism includes a piston cylinder fixedly connected to the right side of the L-shaped plate, a piston block that can slide left and right is arranged in the piston cylinder, and a connecting strip is rotatably connected to the eccentric position of the lower end of the pulley located on the right side, and the other end of the connecting strip is rotatably connected to the piston block.

[0013] Preferably, the right side space of the piston cylinder is connected to the outside through a one-way port, and the right side space of the piston cylinder is connected with a one-way tube, the other end of the one-way tube is connected to the upper end of the rotating tube through a rotating joint, a plurality of air holes are opened on the outer wall of the rotating cylinder, and a friction plate is fixedly connected to the inner bottom of the rotating cylinder, and one-way valves are installed inside the one-way port and the one-way tube, and the one-way valve inside the one-way port flows from right to left, and the one-way valve inside the one-way tube flows from the right side space of the piston cylinder to the inside of the rotating tube in one direction.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The second motor drives the pulley and the transmission belt to rotate the rotating tube and the rotating cylinder connected thereto. This rotation not only cooperates with the cleaning effect of the ultrasonic component, but also stirs the diaphragm through multiple stirring shafts, effectively improving the uniformity and efficiency of cleaning and ensuring that all parts of the diaphragm can be fully cleaned.

[0016] 2. During the rotation process, a one-way gas flow is generated in the outside, piston cylinder, one-way tube, rotating tube and the bottom of the rotating cylinder through the specially designed piston block, one-way port and one-way valve inside the one-way tube. These gas flows eventually enter the inside of the cage in the form of bubbles, which greatly promotes the flow and circulation of water, helps to evenly distribute the cleaning liquid on the surface of the diaphragm, and further improves the cleaning effect.

[0017] 3. After cleaning is completed, the first motor rotates in the opposite direction to move the rotating tube upward and drive the net box to move upward. At this time, the second motor is started again, and the friction between the piston plate and the horizontal bar is used to rotate the net box. This rotation can use centrifugal force to shake off the water adhering to the diaphragm, achieving an efficient drying effect and providing convenience for subsequent process operations.

[0018] 4. During the drying process, the gas bulging out of the piston cylinder is discharged through multiple air holes, which, combined with the drying action, further accelerates the drying speed of the diaphragm. This method of air drying using gas flow not only improves the drying efficiency, but also helps to reduce the impact of residual moisture on the performance of the diaphragm.

[0019] In summary, the rotation function plays a vital role in the cleaning equipment. It not only enhances the cleaning effect, but also promotes water flow, achieves efficient drying and improves drying efficiency, bringing significant beneficial effects to the cleaning and drying process of the diaphragm.

[0029] As an embodiment of the present invention, a cleaning mechanism is also included. The cleaning mechanism includes a net box 10 disposed in the housing 1. The net box 10 is a box structure with a plurality of holes formed in the side wall and the inner bottom. A rotating cylinder 17 is rotatably connected to the inner bottom of the net box 10. A plurality of stirring shafts 19 are fixedly connected to the outer side of the rotating cylinder 17. A horizontal bar 15 is fixedly connected to the upper end of the net box 10.

Next, the first motor 4 is a servo motor that can change the direction of rotation. The servo motor can control the speed and has a very accurate position accuracy. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main feature is that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque;

[0032] As an embodiment of the present invention, the upper end of the rotating tube 16 passes through the horizontal portion of the L-shaped plate 9, and a mounting frame 20 is installed on the upper end of the horizontal portion of the L-shaped plate 9. A second motor 21 is installed on the mounting frame 20. A pulley 23 is installed on the output shaft of the second motor 21 and the rotating tube 16. The two pulleys 23 are connected through a transmission belt 14.

[0033] As an embodiment of the present invention, it also includes an auxiliary mechanism, which is used to improve the cleaning effect and the drying effect. The auxiliary mechanism includes a piston cylinder 24 fixedly connected to the right side of the L-shaped plate 9, a piston block 28 that can slide left and right is arranged in the piston cylinder 24, a connecting strip 25 is rotatably connected to the eccentric position of the lower end of the pulley 23 on the right side, and the other end of the connecting strip 25 is rotatably connected to the piston block 28, the right side space of the piston cylinder 24 is connected to the outside through a one-way port 29, the right side space of the piston cylinder 24 is connected to a one-way tube 30, and the other end of the one-way tube 30 is connected to the upper end of the rotating tube 16 through a rotary joint 22, a plurality of air holes 18 are opened on the outer side wall of the rotating cylinder 17, a friction plate 27 is fixedly connected to the inner bottom of the rotating cylinder 17, and one-way valves are installed inside the one-way port 29 and the one-way tube 30, the one-way valve inside the one-way port 29 flows from right to left, and the one-way valve inside the one-way tube 30 flows from the right side space of the piston cylinder 24 to the inside of the rotating tube 16 in one direction.

[0034] In the present invention, when in use, first add a proper amount of water to the cleaning tank 2, then put the diaphragm to be recycled and cleaned into the net box 10, and then start the first motor 4 to rotate forwardly. The rotation of the first motor 4 will drive the slider 7 to move downward. After the slider 7 moves downward, it will drive the L-shaped plate 9 to move downward through the connecting plate 8, and then use the rotating tube 16 to partially move the net box 10 downward. When the lower end surface of the net box 10 contacts the U-shaped support plate 13, the rotating tube 16 continues to move downward, which will cause the piston plate 26 to move downward relative to the friction plate 27 until the piston plate 26 contacts the friction plate 27 and abuts against it. Then, the first motor 4 is turned off, the ultrasonic component 12 is started, and the second motor 21 is started at the same time. After the second motor 21 is started, the transmission of the pulley 23 and the transmission belt 14 will cause the rotating tube 16 to rotate. The friction effect can drive the rotating cylinder 17 to rotate, and the diaphragm can be stirred by using multiple stirring shafts 19. In cooperation with the ultrasonic component 12, a better cleaning effect is achieved.

[0035] In addition, during this process, the rotation of the right pulley 23 will also use the connecting strip 25 to make the piston block 28 reciprocate left and right. The reciprocating movement of the piston block 28, in conjunction with the one-way port 29 and the one-way valve inside the one-way tube 30, can generate a one-way gas flow in the outside, the piston cylinder 24, the one-way tube 30, the rotating tube 16 and the bottom of the rotating cylinder 17. Finally, the gas will be discharged from the multiple air holes 18 at the bottom, generating a one-way gas flow, which eventually enters the inner side of the net box 10 in the form of bubbles, thereby promoting the flow of water and promoting cleaning.

[0036] After cleaning is completed, the first motor 4 is started to rotate in the opposite direction, which will cause the rotating tube 16 to move upward. The upward movement will cause the piston plate 26 to move upward relative to the rotating cylinder 17 first, so that the upper end surface of the piston plate 26 contacts the horizontal bar 15. At this time, its upward movement will drive the net box 10 to move partially upward. When it moves up to leave the liquid surface of the water body, the first motor 4 is turned off and the second motor 21 is started. At this time, the rotation of the rotating tube 16 will utilize the friction of the piston plate 26 and the horizontal bar 15 to rotate the net box 10, thereby utilizing the centrifugal force to throw off the adhered water, which is convenient for the subsequent next process operation. At this time, the gas bulging out of the piston cylinder 24 will eventually be discharged from the multiple air holes 18. In this way, air drying can be used to further improve the drying effect.
