Description

Technical Field

[0001] This invention relates to the field of aluminum composite panel recycling, and more particularly to an environmentally friendly aluminum composite panel processing device. Background Technology

[0002] Waste aluminum composite panel recycling refers to an environmentally friendly process that extracts aluminum and plastic from discarded building decoration panels or billboards through crushing, washing, drying, sorting, and regeneration.

[0003] In the recycling process of aluminum composite panels, the composition of the crushed material is complex, mainly consisting of aluminum metal particles, plastic, and ferromagnetic metal impurities such as iron nails and screws. Existing processes typically use eddy current separators to separate the cleaned and dried material, using the repulsive force generated by an alternating magnetic field to separate aluminum metal and ferromagnetic metal. However, because waste aluminum composite panels are often mixed with other waste metal impurities during recycling, the content of ferromagnetic metal in the crushed material is relatively high. During the sorting process, these ferromagnetic metals easily carry away small aluminum particles, causing aluminum metal to be lost with the iron waste. At the same time, if ferromagnetic metals enter the eddy current separation stage, they will also interfere with the stability of the alternating magnetic field, reduce the aluminum-plastic separation accuracy, and seriously affect the purity of the subsequently recycled aluminum and plastic particles. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an environmentally friendly aluminum composite panel processing device.

The material feeding plate is located at the front end of the conveyor belt; several hot air pipes for drying metal materials are installed at the rear end of the drying chamber; the hot air pipes are distributed between the connection between the washing tank and the drying chamber and the conveyor belt; each hot air pipe is connected to an external hot air supply device through a connector, and the air outlet of the hot air pipe faces upward; a suction pipe for extracting water vapor is fixed inside the drying chamber; several air blowing pipes for blowing and turning the metal materials are installed at the rear end of the drying chamber; all air blowing pipes are connected to an external air pump through a connector; and the air outlet of the air blowing pipes faces upward; some air blowing pipes are located between the hot air pipes, and some air blowing pipes are located at the rear end of the conveyor belt; an interception component for intercepting plastic materials is installed in the washing tank.

[0007] Optionally, the suction pipe is located at the connection between the washing tank and the drying chamber.

[0008] Optionally, each support plate is provided with several protruding rods.

[0009] Optionally, it also includes scrapers; the machine base is provided with scrapers that are attached to the underside of the conveyor belt and used to scrape off metal materials; each scraper is located above a corresponding bearing plate.

[0010] Optionally, the interception assembly includes a slide rail, an electric slider, and an interception plate; two symmetrically distributed slide rails are fixedly connected in the cleaning tank of the machine; an electric slider is slidably connected to each slide rail; an interception plate for intercepting plastic materials is fixedly connected to all electric sliders; the lower side of the interception plate is below the liquid level and close to the baffle on the conveyor belt.

[0012] Optionally, each feed roller is located in front of its corresponding support plate.

[0013] Compared with existing technologies, this invention has the following advantages: By using a conveyor belt in conjunction with a large magnetic plate, the ferromagnetic metal is first separated from the mixed material before the aluminum composite panel crushed material enters the eddy current separator. This solves the problem of aluminum metal loss along with iron waste caused by ferromagnetic metal inclusions. On this basis, through the alternating work of a small magnetic plate and a vibrating support plate, the ferromagnetic metal adsorbed on the conveyor belt is subjected to multiple cycles of "adsorption-flattening-re-adsorption" purification. During the flattening process of the support plate, the aluminum metal particles that were originally wrapped, stacked, or electrostatically adsorbed by the ferromagnetic metal are released and fall back to the conveyor belt, thereby achieving deep pre-separation of ferromagnetic metal and aluminum metal. This process greatly reduces the interference of impurities entering the subsequent eddy current separation stage and improves the aluminum metal recovery rate. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0017] Example 1: As Figures 1-5 As shown, an environmentally friendly aluminum composite panel processing device includes a machine platform 1 and a conveyor belt 2. The machine platform 1 is equipped with the conveyor belt 2, which has several micro-holes. The conveyor belt 2 is equipped with several evenly distributed baffles 2001. The machine platform 1 is equipped with a washing tank 1001 and a drying chamber 1002 that are interconnected. The baffles 2001 smoothly lift the metal material from the washing tank 1001 into the drying chamber 1002. The conveyor belt 2 passes through the washing tank 1001 and the drying chamber 1002. An ultrasonic generator is installed in the washing tank 1001. It also includes a conveyor belt 3, a feeding plate 4, a large magnetic plate 8, a hot air pipe 101, a suction pipe 102, an air blowing pipe 103, and an interception assembly; the conveyor belt 3 is located at the front end of the drying chamber 1002; a large magnetic plate 8 is installed on the machine base 1 and is in contact with the inner side of the conveyor belt 3; the feeding plate 4 is located above the conveyor belt 2 at the front of the machine base 1; the feeding plate 4 is located at the front end of the conveyor belt 3; several hot air pipes 101 are installed at the rear end of the drying chamber 1002; the hot air pipes 101 are distributed between the connection between the washing tank 1001 and the drying chamber 1002 and the conveyor belt 3. Each hot air duct 101 is connected to an external hot air supply device via a connector, and the air outlet of the hot air duct 101 faces upward; a suction pipe 102 connected to an external suction pump is fixedly connected inside the drying chamber 1002; several air blowing pipes 103 are provided at the rear end of the drying chamber 1002; all air blowing pipes 103 are connected to an external air pump via a connector, and the air outlet of the air blowing pipes 103 faces upward; some air blowing pipes 103 are located between the hot air ducts 101, and some air blowing pipes 103 are located at the rear end of the conveyor belt 3; an interception component is provided inside the cleaning tank 1001.

[0018] It also includes small magnetic plates 5, bearing plates 6, vibrating motors 201, and connecting rods 202; several small magnetic plates 5 are arranged in a straight array on the machine base 1 and are attached to the inner inclined surface of the conveyor belt 3; several bearing plates 6 are connected to the machine base 1 by springs; all bearing plates 6 and all small magnetic plates 5 are staggered, and the bearing plates 6 are set in an inclined shape with the front lower and the back higher; the width of the small magnetic plates 5 is greater than the distance between two adjacent bearing plates 6; the last bearing plate 6 is located at the front end of the large magnetic plate 8; the vibrating motor 201 is fixedly connected to the lower side of the foremost bearing plate 6; two symmetrically distributed connecting rods 202 are fixedly connected between each two adjacent bearing plates 6.

[0019] The suction pipe 102 is located at the connection between the washing tank 1001 and the drying chamber 1002. It draws the water vapor generated during drying toward the washing tank 1001 side to prevent the water vapor from adhering to the metal material being dried at the front of the conveyor belt 2.

[0020] Each bearing plate 6 is provided with several protruding rods.

[0021] It also includes scrapers 7; scrapers 7 are provided on the machine base 1 to fit against the lower side of the conveyor belt 3; each scraper 7 is located above the corresponding bearing plate 6.

[0022] The interception assembly includes a slide rail 301, an electric slider 302, and an interception plate 303; two symmetrically distributed slide rails 301 are fixedly connected in the cleaning tank 1001 of the machine 1; an electric slider 302 is slidably connected to each slide rail 301; an interception plate 303 is fixedly connected to all the electric sliders 302; the lower side of the interception plate 303 is lower than the liquid level and close to the baffle 2001 on the conveyor belt 2.

[0023] When recycling metal-containing waste, the waste is first crushed by an external crushing device. Then, the crushed waste is carried into the washing tank 1001 by conveyor belt 2 for ultrasonic cleaning. Ultrasonic cleaning removes oil from the crushed waste, facilitating subsequent sorting. At the same time, non-metallic materials (plastics) in the crushed waste are floated, separating them from the metals. As the conveyor belt 2 continues to operate, the non-metallic materials floating on the surface of the washing tank 1001 and suspended in the liquid are further processed. The metal material is intercepted by the interceptor plate 303 and then gradually transported to the drying chamber 1002 for drying after moving along the conveyor belt 2 past the interceptor plate 303. Subsequently, the electric slider 302 drives the interceptor plate 303 to slide backward on the slide rail 301 to collect and clean the intercepted plastic material. Then, the external hot air supply equipment is controlled to deliver hot air into the drying chamber 1002 from the hot air pipe 101 to dry the metal material. At the same time, the external suction pump is controlled to suck out the water vapor generated in the drying chamber 1002 from the suction pipe 102.

[0024] Furthermore, during the drying process, the external pump is intermittently controlled to pump airflow at a pressure of 0.1-0.3 MPa from the air pipe 103 to the conveyor belt 2, so that the metal material is blown and turned over by the airflow during the drying process, ensuring that the accumulated metal material is fully dried.

[0025] After the metal material is dried and conveyed to the area below the conveyor belt 3, the large magnetic plate 8 attracts the ferromagnetic metal material to the underside of the conveyor belt 3. The ferromagnetic metal material is then conveyed by the conveyor belt 3 to the area above the discharge plate 4, where it accumulates at the point of separation from the front end of the large magnetic plate 8. As the ferromagnetic metal material accumulates and the conveyor belt 3 moves, the ferromagnetic metal material gradually falls onto the discharge plate 4 and is discharged. Meanwhile, the non-magnetic aluminum particles continue to be conveyed on the conveyor belt 2 until they are discharged. The discharged ferromagnetic metal material and aluminum particles are then separated in batches by an external eddy current magnetic separator. In summary, by classifying the ferromagnetic metal material and aluminum particles before eddy current separation after drying, and then further classifying them for eddy current separation, the separation accuracy is improved.

[0026] Furthermore, after the metal material is conveyed through the drying chamber 1002 to below the conveyor belt 3, an external pump intermittently pumps air at a pressure of 0.1-0.3 MPa into the air blowing pipe 103 located below the conveyor belt 3 to disperse the metal material, which is beneficial for the large magnetic plate 8 to adsorb the ferromagnetic metal material.

[0027] In the above description, the front end of the large magnetic plate 8 is located above the feed plate 4. In the following description, the front end of the large magnetic plate 8 is located away from the feed plate 4.

[0028] Considering that the metal material is in an accumulated state on the conveyor belt 2, when the large magnetic plate 8 adsorbs the ferromagnetic metal material, aluminum metal particles are easily mixed, wrapped, or electrostatically adsorbed by the iron-based metal and are adsorbed together to the lower side of the conveyor belt 3, resulting in aluminum metal loss and a decrease in pre-sorting effect, affecting the accuracy of subsequent eddy current sorting. Therefore, after the metal material is conveyed into the drying chamber 1002, the vibration motor 201 is controlled to drive all the bearing plates 6 to vibrate through the connecting rod 202. When the metal material is dried and conveyed to the lower side of the conveyor belt 3, the ferromagnetic metal material mixed with aluminum metal particles is adsorbed by the large magnetic plate 8. The magnetic plate 8 is attracted to the lower side of the conveyor belt 3. The aluminum metal particles are continuously conveyed forward with the conveyor belt 2. When the ferromagnetic metal material mixed with aluminum metal particles is conveyed to the top of the support plate 6, the ferromagnetic metal material mixed with aluminum metal particles accumulates at the position separated from the front end of the large magnetic plate 8 as the conveyor belt 3 moves. With the accumulation of ferromagnetic metal material and the movement of the conveyor belt 3, the ferromagnetic metal material and the mixed aluminum metal particles gradually fall onto the vibrating support plate 6. Since the support plate 6 is set in an inclined shape with a lower front and a higher back, the metal material falling on the support plate 6 vibrates forward and spreads evenly.

[0029] As the flattened metal material moves forward with the vibration of the bearing plate 6 to below the small magnetic plate 5, the ferromagnetic metal material on the bearing plate 6 is once again attracted to the lower side of the conveyor belt 3 by the small magnetic plate 5. Meanwhile, the aluminum metal particles that were previously mixed with the ferromagnetic metal material gradually fall from the front side of the bearing plate 6 onto the conveyor belt 2 after being flattened, thus removing the aluminum metal particles mixed in with the magnetic metal material.

[0030] Furthermore, after the ferromagnetic metal material is attracted to the lower side of the conveyor belt 3 by the small magnetic plate 5 and conveyed forward to the upper side of the next bearing plate 6, the ferromagnetic metal material gradually separates from the small magnetic plate 5 and falls onto the next vibrating bearing plate 6 for secondary flattening. The above sorting operation is repeated. After the ferromagnetic metal material has been flattened and magnetically attracted multiple times, the magnetic metal material after the third flattening and magnetic attraction is attracted to the lower side of the conveyor belt 3 by the small magnetic plate 5 at the front, and the ferromagnetic metal material is moved to the upper side of the discharge plate 4 for discharge, so as to ensure that aluminum metal particles mixed in the magnetic metal material are removed.

[0031] Furthermore, by setting several protruding rods on the support plate 6 to block the metal material, the metal material falling on the support plate 6 is vibrated forward and spread evenly, while preventing the metal material from falling quickly from the support plate 6 onto the conveyor belt 2, and preventing ferromagnetic metal material from falling back onto the conveyor belt 2, thus affecting the pre-sorting effect.

[0032] Furthermore, when the current batch of metal materials is about to complete the pre-sorting, the magnetization of the large magnetic plate 8 and the small magnetic plate 5 is stopped in sequence, so that the ferromagnetic metal materials of the current batch fall onto the feed plate 4 after the pre-sorting is completed, while the aluminum metal particles are conveyed by the conveyor belt 2 until they are discharged, thus completing the pre-sorting of the last metal materials of the current batch.

[0033] Furthermore, considering that after the metal materials are demagnetized (small magnetic plate 5, large magnetic plate 8), static electricity is easily generated due to friction and changes in the magnetic field. As a result, some materials (including ferromagnetic metals and aluminum metal particles) adhere to the surface of the conveyor belt 3 due to static electricity after demagnetization, affecting the pre-sorting effect. Therefore, the surface of the conveyor belt 3 is scraped off by the scraper 7, and the adhered metal materials are forcibly scraped off and guided to fall onto the bearing plate 6, effectively avoiding the problem of metal material retention caused by static adhesion.

[0034] In summary, this invention, through the cooperation of the conveyor belt 3 and the large magnetic plate 8, pre-treats the metal material before eddy current separation. During subsequent eddy current separation, this reduces the entrainment of aluminum metal particles by ferromagnetic metal, thereby improving the recovery rate of aluminum metal particles. Furthermore, by alternating between the small magnetic plate 5 and the vibrating support plate 6, the metal material undergoes multiple cycles of "adsorption-flattening-re-adsorption," allowing the aluminum metal particles entrained in the pre-separation stage to be fully exposed and separated during the flattening process. This enhances the pre-treatment effect on the metal material and improves the accuracy of subsequent eddy current separation.

[0035] Example 2: Based on Example 1, as follows Figure 4 and Figure 5 As shown, it also includes a material-distributing roller 401; several material-distributing rollers 401 located on the lower side of the conveyor belt 3 are rotatably connected on the machine base 1; the material-distributing rollers 401 are connected to an external motor; each material-distributing roller 401 is located below a small magnetic plate 5. By rotating the material-distributing rollers 401, the magnetic metal materials accumulated on the lower side of the conveyor belt 3 are continuously dispersed, so that the non-magnetic metal materials mixed in are separated and fall back onto the conveyor belt 2 during the distributing process, thereby enhancing the pre-sorting effect of metal materials.

[0036] Each feeding roller 401 is located in front of the corresponding support plate 6 to prevent non-magnetic metal materials scattered by the feeding roller 401 from falling onto the support plate 6, and to prevent non-magnetic metal materials that have fallen onto the support plate 6 from being driven by magnetic metal materials to re-adhere to the conveyor belt 3.
