Description

Technical Field

[0001] The present invention relates to the technical field of aluminum-plastic separation, and particularly relates to a high-voltage electrostatic aluminum-plastic separation and crushing production system and process. Background Art

[0002] The high-voltage electrostatic aluminum-plastic separation and crushing production system is an advanced technology for separating the aluminum layer and the plastic layer in aluminum-plastic composite materials. This system combines physical crushing and high-voltage electrostatic separation to achieve efficient recycling and reuse of aluminum and plastic. Among them, as one of the aluminum-plastic combinations with the most waste, during the production process of medicine boards, in order to improve the sealing of drugs, the aluminum material and the plastic material are tightly adhered, resulting in difficult separation of aluminum and plastic during subsequent recycling. Therefore, a high-voltage electrostatic aluminum-plastic separation and crushing device is required.

[0003] Compared with the existing aluminum-plastic separation and crushing devices, there are still the following defects: Conventional aluminum-plastic separation devices use high-temperature boiling separation or directly use mechanical force for separation, which easily leads to incomplete separation. Due to the tight adhesion of the aluminum material and the plastic material, there is a problem of more aluminum material remaining in the separated matter. Moreover, medicine boards that are not dried and not crushed up to standard will reduce the production efficiency during high-voltage electrostatic separation. At the same time, if the broken particles of the aluminum-plastic board do not meet the standard, the separation of the aluminum material and the plastic material during high-voltage electrostatic separation will not be thorough enough. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-voltage electrostatic aluminum-plastic separation and crushing production system and process to solve the following technical problems: Conventional aluminum-plastic separation devices use high-temperature boiling separation or directly use mechanical force for separation, which easily leads to incomplete separation. Due to the tight adhesion of the aluminum material and the plastic material, there is a problem of more aluminum material remaining in the separated matter. Moreover, medicine boards that are not dried and not crushed up to standard will reduce the production efficiency during high-voltage electrostatic separation. At the same time, if the broken particles of the aluminum-plastic board do not meet the standard, the separation of the aluminum material and the plastic material during high-voltage electrostatic separation will not be thorough enough.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A high-voltage electrostatic aluminum-plastic separation and crushing production system and process, including: a high-voltage electrostatic box, above which there is a screening frame for vibrating and screening aluminum-plastic materials. Above the screening frame, there is a crushing box for crushing the aluminum-plastic materials poured from the feeding port. Behind the screening frame, there is a feeding frame capable of conveying the aluminum-plastic materials.

[0007] Inside the high-voltage electrostatic box, there is a separation roller for differentiating and separating aluminum particles and plastic particles. Below the high-voltage electrostatic box, there are a first collection box and a second collection box for separately storing aluminum particles and plastic particles.

[0008] As a further solution of the present invention: a diversion cover plate is threadedly connected above the high-voltage electrostatic box, and both the left and right sides of the lower part inside the high-voltage electrostatic box are inclined, which are used for draining and guiding aluminum particles and plastic particles to be discharged.

[0009] As a further solution of the present invention: screening frame plates are arranged on both the upper and lower sides inside the screening frame, and a first diversion bottom plate for guiding aluminum particles and plastic particles is fixedly connected to the lower end of the middle part of the screening frame plate;

[0010] Vibration motors are arranged at the four corners of the lower end of the screening frame plate, and damping springs connected to the screening frame are arranged below the vibration motors.

[0011] As a further solution of the present invention: the screening frame plate forms an elastic telescopic structure on the screening frame through damping springs, and the inside of the screening frame plate is inclined from front to back, which is used for guiding and discharging unfiltered aluminum particles and plastic particles;

[0012] The screening frame plate and the filter mesh plate are connected by a clamping method.

[0013] As a further solution of the present invention: the lower side at the rear end of the screening frame is inclined backward and is communicated with the feed pipe;

[0014] High-voltage motors are fixedly installed on both the left and right sides below the screening frame.

[0015] As a further solution of the present invention: a rear back plate is threadedly connected through a third adjusting bolt at the rear side of the crushing box body, a gear disk is arranged in front of the rear back plate, a crushing shaft roller is arranged in front of the gear disk, and a linkage shaft block connected to the crushing box body is arranged in front of the crushing shaft roller.

[0016] As a further solution of the present invention: both the gear disk and the linkage shaft block are connected to the crushing shaft roller by a clamping method, and the gear disk forms a meshing connection with another monomer;

[0017] The crushing shaft roller is in a fitting setting with another monomer, and grooves are equidistantly arranged on the outer side of the crushing shaft roller.

[0018] As a further solution of the present invention: the crushing box body and the feeding port form a communicating structure, the longitudinal section of the feeding port is funnel-shaped, which is used for guiding and discharging materials, and the upper surface of the feeding port is in a fitting setting with the discharge pipe.

[0019] As a further solution of the present invention: a blower is provided on the lower side inside the feeding frame for blowing aluminum particles and plastic particles upward. A cavity is formed inside the feeding frame, and the size of the cavity is the same as that of the cavity formed inside the discharge pipe.

[0020] As a further solution of the present invention: the high-voltage electrostatic aluminum-plastic separation and crushing production system described in any one of claims 1-9 is adopted, and specifically includes the following steps:

[0021] S1: Feeding and crushing. The material is fed into the crushing box from the feeding port. At this time, the second servo motor is turned on to rotate the gear disc, so as to use the crushing shaft roller to crush the material and make the material reach the required particle size.

[0022] S2: Vibration screening. On the basis of S1, after the material is crushed, it will fall into the screening frame plate. There are damping springs located inside the screening frame at the lower end of the vibration motor. When the vibration motor operates, the screening frame plate will vibrate up and down, so as to use the filter screen plate to vibrate and screen the crushed material. After double-layer filtration, the qualified material will flow directly downward, while the unqualified material will enter the feeding frame along the groove body inclined inside the screening frame plate.

[0023] S3: Circulating crushing. On the basis of S2, the uncrushed material enters the feeding frame along the feeding pipe. At this time, the blower is turned on to blow the material upward, then it enters the feeding port along the discharge pipe, and then falls into the crushing box for re-crushing.

[0024] S4: Aluminum-plastic separation. On the basis of S2, the qualified material particles will be separated by high-voltage static electricity under the action of the high-voltage motor, so that the material is separated into individual aluminum particles and plastic particles.

[0025] S5: Collecting materials. Finally, combining S1-S4, the aluminum particles and plastic particles fall onto the separation roller. Through the clockwise rotation of the separation roller, at this time, the aluminum particles are conductive and will quickly induce charges in the high-voltage electrostatic field, forming polarization charges opposite to the direction of the electric field. As the corona makes the aluminum particles negatively charged, they are adsorbed by the separation roller and finally fall along the separation roller due to gravity and enter the first collection box. While the plastic particles are insulators and will be repelled by the electric field under the rotation of the separation roller and bounce off and fall into the second collection box, thus completing the aluminum-plastic separation.

[0026] The beneficial effects of the present invention:

[0027] 1. By using the sieve frame, crushing box body and feeding frame in cooperation, the medicine plate material can be subjected to cyclic crushing treatment, so that the particle size of the medicine plate material can reach the high-voltage electrostatic separation standard under cyclic crushing, avoiding the phenomenon that it is difficult to separate in the subsequent process due to the large particle diameter.

[0028] Furthermore, the high-voltage electrostatic box, sieve frame, crushing box body and feeding frame are all detachable structures, which is convenient for independent disassembly, replacement or repair when a certain part is damaged subsequently, making the device quick to install and saving cost resources to avoid waste.

[0039] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0040] Please refer to Figure 1-8 As shown, the present invention is a high-voltage electrostatic aluminum-plastic separation and crushing production system and process.

[0041] Embodiment 1

[0042] Please refer to Figure 1 、 Figure 2 and Figure 6 In, the present invention provides a technical solution: a high-voltage electrostatic box 1, a screening frame 5 for vibrating and screening aluminum-plastic is arranged above the high-voltage electrostatic box 1, a crushing box body 6 is arranged above the screening frame 5 for crushing the aluminum-plastic material poured from the feeding port 8, and a feeding frame 7 capable of conveying the aluminum-plastic material is arranged at the rear side of the screening frame 5;

[0043] Furthermore, screening frame plates 502 are arranged on both the upper and lower sides inside the screening frame 5, and a first flow guide bottom plate 503 for guiding aluminum particles 9 and plastic particles 10 is fixedly connected to the lower end of the middle part of the screening frame plate 502;

[0044] Vibration motors 504 are arranged at the four corners of the lower end of the screening frame plate 502, and damping springs 505 connected to the screening frame 5 are arranged below the vibration motors 504.

[0045] Furthermore, the screening frame plate 502 forms an elastic telescopic structure on the screening frame 5 through the damping spring 505, and the interior of the screening frame plate 502 is arranged to be inclined from front to back, so as to guide and discharge the unfiltered aluminum particles 9 and plastic particles 10;

[0046] The screening frame plate 502 and the filter screen plate 506 are connected by snap-fitting.

[0047] Furthermore, the lower side of the rear end of the screening frame 5 is arranged to be tilted backwards and is connected to the feed pipe 701;

[0048] High voltage motors 507 are fixedly installed on both left and right sides below the screening frame 5 .

[0049] Specifically, firstly, the high-voltage electrostatic box 1 is stably placed at the designated position through the fixed base frame 2, and then the first collection box 3 and the second collection box 4 are stacked and placed on the inner side of the fixed base frame 2 and aligned with the lower end center of the high-voltage electrostatic box 1. At this time, the discarded medicine plate material is put into the crushing box 6 from the feed port 8. When the second servo motor 603 is turned on to rotate the gear plate 604, the crushing shaft roller 605 can be driven to rotate synchronously, so that the medicine plate material is crushed by utilizing the fitting setting between the crushing shaft roller 605 and another monomer, and then drained downward along the second guide bottom plate 607 fixedly connected to the lower end of the crushing box 6 to enter the next step;

[0050] Furthermore, the gear plate 604 and the linkage shaft block 606 are connected to the crushing shaft roller 605 in a snap-fitting manner. When the second servo motor 603 is turned on to rotate the gear plate 604, the gear plate 604 can be meshed with another unit, so that the gear plate 604 and the other unit rotate in the opposite direction, thereby causing the crushing shaft roller 605 to generate a relative rotational force, so as to effectively crush the medicine plate material. The crushing box 6 and the back plate 601 are connected in a threaded manner through the third adjusting bolt 602, so that after the back plate 601 is disassembled later, the gear plate 604, the crushing shaft roller 605 and the linkage shaft block 606 can be disassembled, replaced, repaired or cleaned to avoid blockage or jamming caused by long-term crushing.

[0051] Embodiment 2

[0052] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7In this, the present invention provides a technical solution: a rear plate 601 is provided at the rear side of the crushing box body 6 and is threadedly connected by a third adjusting bolt 602. A gear disk 604 is provided in front of the rear plate 601. A crushing shaft roller 605 is provided in front of the gear disk 604. A linkage shaft block 606 connected to the crushing box body 6 is provided in front of the crushing shaft roller 605.

[0053] Further, both the gear disk 604 and the linkage shaft block 606 are connected to the crushing shaft roller 605 in a clamping manner, and the gear disk 604 forms a meshing connection with another monomer;

[0054] The crushing shaft roller 605 is arranged in a fitting manner with another monomer, and grooves are equidistantly formed on the outer side of the crushing shaft roller 605.

[0055] Further, a communicating structure is formed between the crushing box body 6 and the feeding port 8. The longitudinal section of the feeding port 8 is funnel-shaped for guiding and discharging materials. The upper surface of the feeding port 8 is arranged in a fitting manner with the discharge pipe 705;

[0056] Further, a blower 702 is provided on the lower side inside the feeding frame 7 for blowing aluminum particles 9 and plastic particles 10 upward. A cavity is formed inside the feeding frame 7, and the size of the cavity is the same as the size of the cavity formed inside the discharge pipe 705.

[0057] Specifically, in combination with Embodiment 1, when the crushed medicine plate material enters the screening frame 5 from the second diversion bottom plate 607 and then falls onto the screening frame plate 502. A damping spring 505 connected to the screening frame 5 is provided at the lower end of the vibration motor 504, and the upper end of the vibration motor 504 is fixedly connected to the screening frame plate 502 and is located at the four lower corners of the screening frame plate 502. When the vibration motor 504 is turned on, the screening frame plate 502 will perform an up-and-down elastic telescopic movement in the screening frame 5 through the damping spring 505, causing the crushed medicine plate material to be vibrationally screened under the action of the filter mesh plate 506, enabling the filtered medicine plate material to enter the screening frame plate 502 provided in the next layer along the first diversion bottom plate 503, and the unfiltered medicine plate material will enter the feed pipe 701 along the inclined setting of the screening frame plate 502. After the vibrational screening of the double-layer screening frame plate 502, when the particle diameter of the medicine plate material reaches the required standard, an electrode charge reaction is directly carried out through the high-voltage motor 507. Among them, the screening frame 5 is threadedly connected to the high-voltage electrostatic box 1 and the crushing box body 6 respectively through the second adjusting bolt 501, facilitating separate disassembly;

[0058] Further, the unqualified medicine board materials enter the cavity inside the feeding frame 7 along the inclined feeding pipe 701. At this time, by turning on the blower 702, the medicine board materials are blown upward, then discharged into the feeding port 8 along the discharging pipe 705, and finally enter the crushing box body 6 again for crushing treatment. Through this cyclic crushing, the particle diameters of the medicine board materials can finally all meet the standards of high-voltage electrostatic separation. Among them, because the medicine board materials are light in quality, they are suitable for being blown by the blower 702, while other heavier materials cannot be used. By using the fourth adjusting bolt 704, the positioning column 703 and the feeding pipe 701 are respectively fixed to the rear sides of the feeding port 8 and the screening frame 5, which can limit and fix the whole feeding frame 7 and can be vertically straightened and calibrated to prevent the medicine board materials from splashing in the cavity of the feeding frame 7 due to the wind speed blown by the blower 702 or other factors and being unable to be discharged from the discharging pipe 705.

[0059] Embodiment 3

[0060] Please refer to Figure 1-Figure 8 In this, the present invention provides a technical solution: adopting the high-voltage electrostatic aluminum-plastic separation and crushing production system according to any one of claims 1-9, which specifically includes the following steps:

[0061] S1: Feeding and crushing. Feed the materials into the crushing box body 6 from the feeding port 8. At this time, turn on the second servo motor 603 to rotate the gear disk 604, so as to use the crushing shaft roller 605 to crush the materials and make the materials reach the required particle size.

[0062] S2: Vibration screening. On the basis of S1, after the materials are crushed, they will fall into the screening frame plate 502. There is a damping spring 505 located inside the screening frame 5 at the lower end of the vibration motor 504. When the vibration motor 504 operates, the screening frame plate 502 will vibrate up and down, so as to use the filter mesh plate 506 to perform vibration screening on the crushed materials. After double-layer filtration, the qualified materials will flow directly downward, while the unqualified materials will enter the feeding frame 7 along the inclined groove body on the inner side of the screening frame plate 502.

[0063] S3: Cyclic crushing. On the basis of S2, the uncrushed materials enter the feeding frame 7 along the feeding pipe 701. At this time, turn on the blower 702 to blow the materials upward, then enter the feeding port 8 along the discharging pipe 705, and then immediately fall into the crushing box body 6 for re-crushing treatment.

[0064] S4: Aluminum-plastic separation. On the basis of S2, the qualified material particles will be subjected to high-voltage electrostatic separation under the action of the high-voltage motor 507, so that the materials are separated into aluminum particles 9 and plastic particles 10.

[0065] S5: Collect the materials. Finally, combining S1 - S4, the aluminum particles 9 and plastic particles 10 fall onto the separation roller 103. Through the clockwise rotation of the separation roller 103, at this time, the aluminum particles 9 are conductive and will quickly induce charges in the high - voltage electrostatic field, forming polarization charges opposite to the direction of the electric field. With the corona effect, the aluminum particles 9 are negatively charged and thus adsorbed by the separation roller 103. Finally, due to gravity, they fall along the separation roller 103 and enter the first collection box 3. While the plastic particles 10 are insulators and will be repelled by the electric field under the rotation of the separation roller 103 and bounce off, falling into the second collection box 4, thus completing the separation of aluminum and plastic.

[0066] Embodiment Four

[0067] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In, the present invention provides a technical solution: Inside the high - voltage electrostatic box 1, there is a separation roller 103 for differentiating and separating the aluminum particles 9 and plastic particles 10. Below the high - voltage electrostatic box 1, there are a first collection box 3 and a second collection box 4 for separately storing the aluminum particles 9 and plastic particles 10.

[0068] Above the high - voltage electrostatic box 1, there is a diversion cover plate 104 threadedly connected through a first adjusting bolt 105. The lower left and right sides inside the high - voltage electrostatic box 1 are both inclined for guiding the drainage of the aluminum particles 9 and plastic particles 10.

[0069] Specifically, combining Embodiment One, Embodiment Two, and Embodiment Three, at this time, the completely crushed medicine - plate materials will be drained along the diversion cover plate 104 to directly above the separation roller 103. When the first servo - motor 101 is turned on, at the same time, the rotation speed of the first servo - motor 101 and the electric - field strength can be controlled through the control panel 102. Since the outer surface of the separation roller 103 is made of stainless - steel material, after the electrode reaction of the high - voltage motor 507, it is differentiated into two individuals: aluminum particles 9 and plastic particles 10. When the separation roller 103 rotates clockwise, the charged aluminum particles 9 are adsorbed by the separation roller 103 and finally fall into the first collection box 3 for collection due to their own gravity. While the insulating plastic particles 10 will repel the charges of the separation roller 103 and thus bounce off and then fall into the second collection box 4 for collection.

[0070] Among them, the diversion cover plate 104 is threadedly connected to the high - voltage electrostatic box 1 through the first adjusting bolt 105, which is convenient for later opening the diversion cover plate 104 to clean or organize the inside of the high - voltage electrostatic box 1. And combined with the inclined setting of the lower side inside the high - voltage electrostatic box 1, it can guide the discharged separated aluminum particles 9 and plastic particles 10 to avoid accumulation inside the high - voltage electrostatic box 1.

[0071] The working principle of the high-voltage electrostatic treatment device is as follows. First, the material to be transported is crushed into 1-5 mm particles as needed. During this process, ensure that the moisture content of the medicine board is <5%, to avoid conductivity interference. After the medicine board is crushed and pulverized, the particles are charged by friction through a vibrating feeder, and the material is evenly dispersed into the high-voltage electrostatic field. At this time, a 30-80 kV DC voltage is applied to the electrodes to form a strong electrostatic field, so that the aluminum particles 9 are adsorbed by the grounded roller, while the plastic particles 10 will be repelled by the same-sex charges due to their insulation and separated by free fall. The aluminum particles 9 are stripped by the rotation of the separation roller 103. Finally, the purity is improved by adjusting the electric field strength or adding a secondary roller, and the aluminum particles 9 and the plastic particles 10 enter the corresponding first collection box 3 and the second collection box 4 for collection respectively. It can achieve efficient sorting of materials by precisely controlling the electrostatic field, so as to achieve the characteristics of pollution-free and low energy consumption. Here, the model of the high-voltage electrostatic treatment device is HES-500.

[0072] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.

At this time, turn on the blower (702) to blow the materials upward, and then enter the feeding port (8) along the discharge pipe (705), and then fall into the crushing box body (6) for re-crushing treatment. S4: Aluminum-plastic separation. On the basis of S2, the qualified material particles will be subjected to high-voltage electrostatic separation under the action of the high-voltage motor (507), so that the materials are separated into individual aluminum particles (9) and plastic particles (10). S5: Collecting materials. Finally, combining S1-S4, the aluminum particles (9) and plastic particles (10) fall centrally onto the separation roller (103). By the clockwise rotation of the separation roller (103), at this time, the aluminum particles (9) are conductive and will quickly induce charges in the high-voltage electrostatic field to form polarization charges opposite to the direction of the electric field. As the corona makes the aluminum particles (9) negatively charged, they are adsorbed by the separation roller (103) and finally fall along the separation roller (103) due to gravity and enter the first collection box (3). While the plastic particles (10) are insulators and will be repelled by the electric field under the rotation of the separation roller (103) and bounce off and fall into the second collection box (4), thus completing the aluminum-plastic separation.
