Description

Technical Field

[0001] This invention belongs to the field of aluminum can recycling technology, specifically relating to a high-temperature paint removal device for waste aluminum cans. Background Technology

[0002] Aluminum aluminum cans are lightweight, aesthetically pleasing, easy to use, and portable, making them one of the most popular packaging materials in the global beverage packaging industry. Currently, approximately 150 billion aluminum cans are consumed worldwide annually, consuming over 2 million tons of aluminum alloy, accounting for about 15% of the world's total aluminum consumption. Because aluminum cans are discarded after use, a large amount of waste aluminum can resources are generated. The recycling process requires paint removal from the cans.

[0003] Chinese invention patent CN107570523A discloses an intelligent robot pipe welding equipment and method, including a housing with a temperature control panel and a speed control panel on its outer wall. A rotating reaction chamber is located inside the housing, with a heating wire on its inner wall. The temperature control panel is connected to the heating wire, and a motor is connected to the rotating reaction chamber. The motor is connected to the speed control panel. A pull-out collection plate is located at the bottom of the rotating reaction chamber, and a debris collection chamber is located below the collection plate, with the upper diameter of the debris collection chamber not less than the lower diameter of the rotating reaction chamber. In the aforementioned application, during the paint stripping process, the paint stripper generates a large amount of paint residue floating on the surface of the paint stripper liquid after contact with the can fragments. This easily reduces the cycle life of the paint stripper, increases the amount of paint stripper used, and increases equipment costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-temperature paint stripping device for waste aluminum cans, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a high-temperature paint stripping device for waste aluminum cans, including a support leg, a paint stripping chamber fixedly connected to the top of the support leg, a feed inlet fixedly connected to the top left side of the paint stripping chamber, a discharge outlet fixedly connected to the right side of the paint stripping chamber, a discharge device movably connected inside the right side of the paint stripping chamber, a feeding device movably connected to the center of the paint stripping chamber, multiple stirring devices movably connected inside the left side of the paint stripping chamber, and multiple heating and heat preservation devices fixedly connected inside the left side of the paint stripping chamber. A bevel gear 1 is fixedly connected to the rear side of the stirring device on the right. Multiple fixed blocks 1 are fixedly connected to the rear surface of the paint stripping chamber. A reciprocating screw is movably connected between two fixed blocks 1. A bevel gear 2 is fixedly connected to the right side of the reciprocating screw. The bevel gear 1 and bevel gear 2 mesh. A movable block is movably connected to the outer side of the reciprocating screw. A telescopic rod is fixedly connected to the top of the movable block. A fixed block 2 is fixedly connected to the top of the telescopic rod. The interior of the fixed block 2 is fixedly connected to one end of the rotating shaft 1. Guide rails are provided on the front and rear surfaces of the paint stripping chamber. The outer side of the rotating shaft 1 is movably connected to the inner surface of the guide rails. A torsion spring is fixedly connected to the interior of the rotating shaft 1. Friction wheels are fixedly connected to both ends of the rotating shaft 1. Friction strips are fixedly connected to the front and rear surfaces of the paint stripping chamber. A scum scraper is fixedly connected to the outer side of the rotating shaft 1. A scum collection box is movably connected to the interior of the paint stripping chamber. When the equipment is in the paint stripping process, the scum scraper is set up. The stirring equipment is started, and the scum scraper moves horizontally back and forth in conjunction with bevel gear one, bevel gear two, reciprocating screw, moving block, friction wheel, friction strip and guide rail. At the same time, the scum scraper pours the paint residue into the scum collection box after it moves to the far right each time. This reduces the paint residue in the paint stripper, so that the paint stripper can be recycled. At the same time, it avoids the paint residue from being suspended and covering the can fragments, which may cause incomplete paint stripping in some areas.

[0006] As a further description of the above technical solution: The scum scraper has multiple drainage holes inside, and the paint stripping chamber is fixedly connected to a bracket, with the top of the bracket contacting the bottom of the scum collection box.

[0007] As a further description of the above technical solution: The movement trajectory of the scum scraper does not contact the outside of the scum collection box, and the horizontal length of the guide rail is greater than the length of the reciprocating screw.

[0008] As a further description of the above technical solution: The bottom of the scum scraper is slightly lower than the liquid level in the paint stripping chamber. The outer side of the scum scraper is never in contact with the outer side of the stirring equipment. The interior of the paint stripping chamber is movably connected with a corner turbulence component.

[0009] As a further description of the above technical solution: The corner turbulence assembly includes a second rotating shaft, a first pulley, a belt, another second pulley, a third rotating shaft, a third fixed block, a third bevel gear, a fourth bevel gear, a fourth rotating shaft, and a turbulence fan blade. A second rotating shaft is fixedly connected to the front end of the left-side stirring device. A first pulley is fixedly connected to the front of the second rotating shaft. Multiple third fixed blocks are fixedly connected to the bottom left side of the paint stripping chamber. The third rotating shaft is movably connected between the third fixed blocks. A second pulley is fixedly connected to the right side of the third rotating shaft. A belt is movably connected to the outer sides of the first and second pulleys. Bevel gears are fixedly connected to the outer sides of both ends of the third rotating shaft. A fourth rotating shaft is movably connected to the inner sides of the left front and rear ends of the paint stripping chamber. A fourth bevel gear is fixedly connected to the bottom of the fourth rotating shaft, and the third bevel gear meshes with the fourth bevel gear. A turbulence fan blade is fixedly connected to the top of the fourth rotating shaft. A corner turbulence component is installed. When the equipment is in the paint stripping process, the paint stripper relies solely on the stirring device to move the can fragments, resulting in a large accumulation of can fragments in the left corner of the paint stripping chamber. At this time, the stirring device rotates, and in conjunction with shaft two, pulley one, belt, pulley two, shaft three, bevel gear three, and bevel gear four, the turbulence fan blades rotate continuously, which continuously sweeps the can fragments in the corner to the center, thereby reducing the accumulation of can fragments in the corner.

[0010] As a further description of the above technical solution: The outer side of the disturbance fan blade does not contact the inner wall of the paint stripping chamber, and the disturbance fan blade is located directly below the center of the feed inlet.

[0011] As a further description of the above technical solution: The outer side of the agitator blades does not contact the outer side of the stirring device, and a paint stripper circulation assembly is fixedly connected inside the paint stripping chamber.

[0012] As a further description of the above technical solution: The paint stripper circulation assembly includes a filter plate, a filter inlet, an inlet pipe, a water pump, a filter chamber, an outlet pipe, a fixing plate, nozzles, and a filling port. The filter inlet is located inside the right side of the paint stripper chamber. A filter plate is fixedly connected to the top of the filter inlet. Multiple filter holes are formed on the surface of the filter plate. The bottom of the filter inlet is fixedly connected to one end of the inlet pipe, and the other end of the inlet pipe is fixedly connected to the water pump. A filter chamber is fixedly connected to the front surface of the paint stripper chamber, and a water pump is fixedly connected to the front surface of the filter chamber. One end of the outlet pipe is fixedly connected to the left side of the filter chamber, and the other end of the outlet pipe is fixedly connected to the right side of the fixing plate. The top left side of the paint stripper chamber is fixedly connected to the bottom of the fixing plate. A filling port is located at the top of the fixing plate. Multiple nozzles are fixedly connected to the left side of the fixing plate, and the outer side of each nozzle is fixedly connected to the inside of the inlet. The paint remover circulation component is set up so that when the equipment has been used for a long time, the paint remover contains a lot of impurities. At this time, the water pump is started, and together with the filter plate, filter port, filter chamber, fixing plate and nozzle, the paint remover enters the filter chamber to filter out the impurities and is then sprayed back into the equipment from the nozzle. This allows the paint remover to be recycled, reducing the amount of subsequent replenishment and reducing the operating cost.

[0013] As a further description of the above technical solution: The filtrate outlet is located between the discharge device and the unloading device, and the nozzle faces diagonally downwards from the feed inlet.

[0014] As a further description of the above technical solution: The top horizontal height of the filter plate is the same as the inner bottom horizontal height of the paint stripping chamber.

[0015] The advantages of this application are: (1) When the equipment is in the paint removal process, the stirring equipment is started, and the bevel gear one, bevel gear two, reciprocating screw, moving block, friction wheel, friction strip and guide rail are used to make the scum scraper move horizontally back and forth. At the same time, the scum scraper moves to the rightmost side each time and pours the paint scum into the scum collection box, thereby reducing the paint scum residue in the paint remover and making the paint remover reusable. At the same time, it avoids the paint scum from being suspended and wrapping the can fragments, causing incomplete paint removal in some areas.

[0016] (2) When the equipment is in the paint stripping process, the paint stripper relies solely on the stirring equipment to move the aluminum can fragments, resulting in a large accumulation of aluminum can fragments in the left corner of the paint stripping chamber. At this time, the stirring equipment rotates, and in conjunction with the rotating shaft 2, pulley 1, belt, pulley 2, rotating shaft 3, bevel gear 3, and bevel gear 4, the agitator blades rotate continuously, causing the aluminum can fragments in the corner to be continuously swept to the center, thereby reducing the accumulation of aluminum can fragments in the corner.

[0017] (3) When the equipment has been used for a long time, the paint remover contains a lot of impurities. At this time, the water pump is started, and the filter plate, filter port, filter chamber, fixed plate and nozzle are used to make the paint remover enter the filter chamber to filter out the impurities and then spray it back into the equipment from the nozzle. This allows the paint remover to be recycled, reducing the amount of subsequent replenishment and reducing the cost of use. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-4 As shown, a high-temperature paint stripping device for waste aluminum cans includes a support leg 100. A paint stripping chamber 200 is fixedly connected to the top of the support leg 100. An inlet 300 is fixedly connected to the top left side of the paint stripping chamber 200. An outlet 400 is fixedly connected to the right side of the paint stripping chamber 200. A discharge device 500 is movably connected inside the right side of the paint stripping chamber 200 to facilitate the unloading process. A discharging device 600 is movably connected to the center of the paint stripping chamber 200 to allow the paint stripper to fully react with the aluminum can fragments. Multiple stirring devices 700 are movably connected inside the left side of the paint stripping chamber 200. Multiple heating and heat preservation devices 800 are fixedly connected inside the left side of the paint stripping chamber 200. A bevel gear 901 is fixedly connected to the rear side of the right-side mixing device 700. Multiple fixed blocks 903 are fixedly connected to the rear surface of the paint stripping chamber 200. A reciprocating screw 904 is movably connected between two fixed blocks 903. A bevel gear 902 is fixedly connected to the right side of the reciprocating screw 904, meshing with the bevel gear 901. A movable block 905 is movably connected to the outer side of the reciprocating screw 904. A telescopic rod 906 is fixedly connected to the top of the movable block 905, allowing the height of the movable block 905 to be adjusted along with the rotating shaft 908. A fixed block 907 is fixedly connected to the top of the telescopic rod 906. The interior of the fixed block 907 is connected to the rotating shaft 908. The paint stripping chamber 200 is fixedly connected to the front and rear surfaces, and guide rails 911 are provided on the front and rear surfaces. One end of the guide rail 911 is curved upwards to provide a buffer and prevent the rotating shaft 908 from being unable to move. The outer side of the rotating shaft 908 is movably connected to the inner surface of the guide rail 911. A torsion spring 909 is fixedly connected inside the rotating shaft 908. Friction wheels 910 are fixedly connected to both ends of the rotating shaft 908. Friction strips 912 are fixedly connected to the front and rear surfaces of the paint stripping chamber 200. The surface of the friction strips 912 is knurled to reduce slippage between the friction wheels 910 and the friction strips 912. A scum scraper 913 is fixedly connected to the outer side of the rotating shaft 908. A scum collection box 914 is movably connected inside the paint stripping chamber 200.

[0022] The scum scraper 913 has multiple drainage outlets inside. A bracket is fixedly connected inside the paint stripping chamber 200, with the top of the bracket contacting the bottom of the scum collection box 914, preventing the box from moving erratically. The movement trajectory of the scum scraper 913 does not contact the outside of the scum collection box 914. The horizontal length of the guide rail 911 is greater than the length of the reciprocating screw 904. The bottom of the scum scraper 913 is slightly lower than the liquid level inside the paint stripping chamber 200. The outside of the scum scraper 913 never contacts the outside of the stirring device 700. A corner baffle assembly 1000 is movably connected inside the paint stripping chamber 200.

[0023] A scum scraper 913 is installed. When the equipment is in the paint removal process, the stirring device 700 is started. In conjunction with bevel gear 1 901, bevel gear 2 902, reciprocating screw 904, moving block 905, friction wheel 910, friction strip 912, and guide rail 911, the scum scraper 913 moves horizontally back and forth. At the same time, after the scum scraper 913 moves to the far right each time, it pours the paint residue into the scum collection box 914. This reduces the paint residue residue in the paint remover, allowing the paint remover to be recycled. It also prevents the paint residue from suspending and wrapping around aluminum can fragments, causing incomplete paint removal in some areas.

[0024] In practical use, when the can fragments enter the paint stripping chamber 200 through the feed inlet 300, the stirring device 700 is activated. This ensures the can fragments come into full contact with the paint stripper. Simultaneously, the stirring device 700 drives the first bevel gear 901 to rotate, which in turn drives the second bevel gear 902. The second bevel gear 902 then drives the reciprocating screw 904, causing the reciprocating screw 904 to move the movable block 905 back and forth. This causes the first rotating shaft 908 to move left and right along the guide rail 911, which in turn drives the scum scraper 913 to move back and forth. When the first rotating shaft 908 reaches the rightmost side of the guide rail 911, it moves diagonally upwards, simultaneously causing the friction wheel 9... When the friction wheel 910 contacts the friction strip 912, it rotates 90 degrees counterclockwise, causing the torsion spring 909 to store energy. At the same time, the rotating shaft 908 rotates with the friction wheel 910, causing the rotating shaft 908 to drive the scum scraper 913 to rotate counterclockwise. This causes the paint residue on the scum scraper 913 to fall into the scum collection box 914, thereby reducing the paint residue residue in the paint remover and allowing the paint remover to be recycled. It also prevents the paint residue from suspending and enveloping the can fragments, causing incomplete paint removal in some areas. When the reciprocating screw 904 continues to rotate, the rotating shaft 908 returns to its original position along the guide rail 911, so that the scum scraper 913 only scrapes scum from left to right. This causes the torsion spring 909 to release its elastic potential energy, so that the rotating shaft 908 always maintains a fixed angle during horizontal movement.

[0025] Example 2, as Figures 1-6As shown, based on Embodiment 1, the corner turbulence assembly 1000 includes a second rotating shaft 1001, a first pulley 1002, a belt 1003, a second pulley 1004, a third rotating shaft 1005, a third fixing block 1006, a third bevel gear 1007, a fourth bevel gear 1008, a fourth rotating shaft 1009, and a turbulence fan blade 1010. The second rotating shaft 1001 is fixedly connected to one end of the front side of the left-side stirring device 700. The first pulley 1002 is fixedly connected to the front side of the second rotating shaft 1001. Multiple third fixing blocks 1006 are fixedly connected to the bottom left side of the paint stripping chamber 200. The third rotating shaft 1005 is movably connected between the third fixing blocks 1006. The second pulley 1004 is fixedly connected to the right side of the third rotating shaft 1005. A belt 1003 is movably connected to the outer side of pulley 1002 and pulley 2 1004. The belt 1003 is set so that the power of pulley 1002 is transmitted to belt 1003, and then belt 1003 transmits the power to pulley 2 1004. The outer sides of the two ends of shaft 3 1005 are fixedly connected to bevel gear 3 1007. The front and rear ends of the left side of paint stripping chamber 200 are movably connected to shaft 4 1009. The bottom of shaft 4 1009 is fixedly connected to bevel gear 4 1008. Bevel gear 3 1007 and bevel gear 4 1008 are both located at the bottom of the outer side of paint stripping chamber 200. Bevel gear 3 1007 meshes with bevel gear 4 1008. The top of shaft 4 1009 is fixedly connected to a disturbance fan blade 1010.

[0026] The outer side of the agitator blade 1010 does not contact the inner wall of the paint stripping chamber 200, and the agitator blade 1010 is located directly below the center of the feed inlet 300. The outer side of the agitator blade 1010 does not contact the outer side of the mixing device 700, and the paint stripping agent circulation assembly 1100 is fixedly connected inside the paint stripping chamber 200.

[0027] The corner turbulence component 1000 is installed. When the equipment is in the paint stripping process, the paint stripper relies solely on the stirring device 700 to move the aluminum can fragments, resulting in a large accumulation of aluminum can fragments in the left corner of the paint stripping chamber 200. At this time, the stirring device 700 rotates, and in conjunction with the rotating shaft 1001, pulley 1002, belt 1003, pulley 1004, rotating shaft 1005, bevel gear 1007, and bevel gear 1008, the turbulence fan blade 1010 rotates continuously, which continuously sweeps the aluminum can fragments in the corner to the center, thereby reducing the accumulation of aluminum can fragments in the corner.

[0028] In practical use, during the paint stripping process, the paint stripper relies solely on the stirring device 700 to move the can fragments, resulting in a large accumulation of can fragments in the left corner of the paint stripping chamber 200. The rotation of the stirring device 700 causes the left-side stirring device 700 to rotate the second rotating shaft 1001, which in turn rotates the first pulley 1002, which in turn rotates the belt 1003, which in turn rotates the second pulley 1002. 04 rotates, causing pulley 2 1004 to drive shaft 3 1005 to rotate, shaft 3 1005 to drive bevel gear 3 1007 to rotate, bevel gear 3 1007 to drive bevel gear 4 1008 to rotate, bevel gear 4 1008 to drive shaft 4 1009 to rotate, shaft 4 1009 to drive the turbulence fan blade 1010 to rotate, so that the aluminum can fragments in the corner are continuously swept to the center, thereby reducing the accumulation of aluminum can fragments in the corner, and at the same time, the paint remover is turbulent, thereby improving the paint removal efficiency.

[0029] Example 3, as Figures 2-8 As shown, based on Embodiment 1 (or Embodiment 2), the paint remover circulation assembly 1100 includes a filter plate 1101, a filter outlet 1102, an inlet pipe 1103, a water pump 1104, a filter chamber 1105, an outlet pipe 1106, a fixing plate 1107, a nozzle 1108, and a filling port 1109. A filter outlet 1102 is provided inside the right side of the paint remover chamber 200. The top of the filter outlet 1102 is fixedly connected to the filter plate 1101. The filter plate 1101 is provided to prevent larger impurities such as aluminum can fragments from entering the water pump 1104. Multiple filter holes 1110 are provided on the surface of the filter plate 1101. The bottom of the filter outlet 1102 is fixedly connected to one end of the inlet pipe 1103, and the other end of the inlet pipe 1103 is connected to... A water pump 1104 is fixedly connected. A filter chamber 1105 is fixedly connected to the front surface of the paint stripping chamber 200. A water pump 1104 is fixedly connected to the front surface of the filter chamber 1105. The left side of the filter chamber 1105 is fixedly connected to one end of the liquid outlet pipe 1106. The other end of the liquid outlet pipe 1106 is fixedly connected to the right side of the fixing plate 1107. The top left side of the paint stripping chamber 200 is fixedly connected to the bottom of the fixing plate 1107. A liquid inlet 1109 is provided on the top of the fixing plate 1107. The liquid inlet 1109 is provided so that when the paint stripper is insufficient, additional paint stripper can be added through the liquid inlet 1109. Multiple nozzles 1108 are fixedly connected to the left side of the fixing plate 1107. The outer side of the nozzles 1108 is fixedly connected to the inside of the feed inlet 300.

[0030] The filter outlet 1102 is located between the discharge device 600 and the unloading device 500, and the nozzle 1108 faces diagonally downwards from the feed inlet 300. The top horizontal level of the filter plate 1101 is the same as the inner bottom horizontal level of the paint stripping chamber 200.

[0031] The paint remover circulation component 1100 is set up so that when the equipment has been used for a long time, the paint remover contains a lot of impurities. At this time, the water pump 1104 is started, which works with the filter plate 1101, filter port 1102, filter chamber 1105, fixing plate 1107 and nozzle 1108 to make the paint remover enter the filter chamber 1105 to filter out the impurities, and then spray it back into the equipment from the nozzle 1108. This allows the paint remover to be recycled, reducing the amount of subsequent replenishment and reducing the operating cost.

[0032] In practical use, after prolonged use, the water pump 1104 is activated, allowing the paint remover to enter the filter port 1102 from the filter plate 1101. This blocks any remaining can fragments in the paint remover through the filter holes 1110 of the filter plate 1101, allowing the paint remover to enter the inlet pipe 1103 from the filter port 1102. The paint remover then enters the filter chamber 1105, where it removes any remaining fine impurities and paint residue. The filtered paint remover then enters the fixed plate 1107 from the outlet pipe 1106, and is sprayed out from the nozzle 1108. This allows the paint remover to be reused after filtration. Additionally, new paint remover can be added from the inlet 1109 as needed, thus saving on chemicals and reducing operating costs.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
