Description

Technical Field

[0001] This invention relates to the field of plastic material recycling technology, specifically to a device for recycling waste materials from the production of composite insulation materials. Background Technology

[0002] Composite insulation material production is a process of combining materials with different properties through specific processes to form composite boards that combine thermal insulation, strength, and durability. The challenge of recycling and utilizing the plastic waste generated in the composite insulation material production process, especially thermosetting plastic waste such as polyurethane, is a significant challenge.

[0003] In the existing composite production process of thermal insulation materials, a certain amount of plastic waste is generated. Currently, these wastes are generally processed into recycled granules through crushing and granulation processes for reuse in the production of plastic products. Before crushing the plastic materials, they need to be cleaned. However, the existing cleaning equipment is not ideal when dealing with wastes with a high degree of pollution. Recycling and granulating these incompletely cleaned wastes will increase the difficulty and cost of subsequent processing, and at the same time cause serious negative impacts on the water environment, atmospheric environment, soil and the entire ecosystem.

Four limiting grooves and four limiting plates are provided, and the four limiting grooves are respectively opened on both sides of the placement frame. The four limiting plates are movably inserted into the four limiting grooves. A spring is fixedly connected between the upper inner walls of the limiting plates and the limiting grooves. Two electric telescopic rods are provided, and the two electric telescopic rods are movably installed on both sides of the inner wall of the placement frame. The movable base plate is movably installed inside the placement frame via a rotating shaft. The cleaning device includes a mounting plate, a second slide block, a connecting frame, a synchronous belt drive mechanism, a lifting platform, a sliding rod, a washing mechanism, and a displacement seat. Two second slide blocks and two connecting frames are provided, with both second slide blocks mounted on the top of the mounting plate. Two connecting frames are respectively mounted on opposite sides of the top of the mounting plate. The synchronous belt drive mechanism is installed between the two connecting frames. The displacement seat is slidably connected to the outer surface of the two second slide blocks. The lifting platform is mounted at one end of the displacement seat. The sliding rod is slidably connected to the end of the lifting platform away from the displacement seat. The washing mechanism is mounted at the bottom end of the sliding rod.

[0006] Furthermore, the electric telescopic rod is movably connected to the movable base plate via a rotating shaft, and the limiting plates on both sides are slidably connected to the two first sliding blocks respectively.

[0007] Furthermore, the synchronous belt drive mechanism is installed together with the displacement seat, and one end of the slide rod is installed together with the track inside the elevator.

[0008] Furthermore, the washing mechanism includes a connecting plate, a motor, and limiting posts. The motor is installed at the top center of the connecting plate, and the output end of the motor passes through the bottom center of the connecting plate and is equipped with a brush rod. There are two limiting posts, and the two limiting posts are respectively fixedly connected to the bottom two sides of the connecting plate.

[0009] Furthermore, the two limiting posts are respectively movably inserted and connected within the two limiting tubes.

[0010] Furthermore, the placement frame is located below the brush handle.

[0011] Furthermore, the processing box is divided into a cleaning area, a drying area, and an installation area by two partitions.

[0012] Furthermore, two partitions are installed inside the processing box, a crusher is installed on one side of the processing box, three fans are installed at equal intervals on one side of the inner wall of the processing box, a heater and a baffle are installed together between one of the partitions and one side wall of the processing box, an inclined panel is installed in the middle of the lower wall of the processing box, and a recovery pipe is installed at one end of the processing box.

[0013] Furthermore, the heater is located below the baffle, one end of the recovery pipe is connected through to three fans, and the top of the inclined panel is configured as an inclined structure.

[0014] Furthermore, a control panel is installed in the middle of one end of the processing box, and a controller is installed on one side of one end of the processing box. The controller is electrically connected to the control panel.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves automated cleaning and drying of heavily contaminated plastic waste through the coordinated operation of multiple components, including a cleaning zone, a drying zone, a limiting tube, springs, limiting columns, a lifting platform, a synchronous belt drive mechanism, a motor, and brush rods. This effectively improves the cleaning quality of plastic waste. In actual operation, the washing liquid and water are first mixed according to a preset ratio and injected into the upper part of the cleaning zone of the treatment tank. The mixture is heated by a heater to raise the water temperature to a suitable range. Then, the placement frame containing the plastic waste is moved into the cleaning zone by the lifting platform. After soaking for a period of time, the motor is started, and its output end drives the brush rod to rotate. The mechanical brushing action removes the fine contaminants remaining on the surface of the plastic waste. At the same time, the lifting platform and synchronous belt drive mechanism complete the lifting and translation of the placement device, improving the cleaning efficiency of plastic waste.

[0016] This invention utilizes the coordinated operation of a drying zone, heater, recycling pipe, and fans. After the plastic waste is cleaned, a synchronous belt drive mechanism and a lifting platform move the placement frame horizontally above the drying zone and then lower it. At this time, three fans are turned on, and the residual heat accumulated at the bottom of the cleaning zone is transported to the drying zone through the recycling pipe, forming a hot air circulation system. The hot air evenly coats the surface of the plastic waste, accelerating moisture evaporation and significantly shortening the drying time. Compared with traditional drying methods, this design of the invention significantly shortens the drying time, not only improving production efficiency but also reducing energy consumption, achieving a win-win situation for both economic and environmental benefits.

[0017] This invention utilizes the coordinated operation of a synchronous belt drive mechanism, electric telescopic rods, a movable base plate, and a crusher. The synchronous belt drive mechanism transfers the placement frame to the installation area above the processing box. Activating the two electric telescopic rods extends their output ends and pushes the movable base plate downwards around the hinge point, forming an inclined unloading channel. Plastic waste automatically falls into the crusher below through the feed inlet along the channel, greatly improving production efficiency and reducing potential errors and safety hazards caused by manual intervention.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Example

[0022] Please see Figure 1 - Figure 8 As shown, a waste recycling device for composite thermal insulation material production includes a processing box 1. First slides 14 are installed on both sides of the top of the processing box 1, and a placement device 7 is slidably connected to the outer surfaces of the two first slides 14. A support frame 5 is installed on the top of the processing box 1, and a cleaning device 6 is installed on both sides of the top of the support frame 5. The placement device 7 includes a placement frame 71, limiting tubes 72, limiting grooves 73, limiting plates 74, electric telescopic rods 76, and a movable base plate 77. There are two limiting tubes 72, which are fixedly connected to the top two sides of the placement frame 71. There are four limiting grooves 73 and four limiting plates 74, which are respectively opened on both sides of the placement frame 71. The four limiting plates 74 are movably inserted into the four limiting grooves 73. A spring 75 is fixedly connected between the upper inner walls of the limiting plates 74 and the limiting grooves 73. There are two electric telescopic rods 76, which are movably installed on both sides of the inner wall of the placement frame 71. The movable base plate 77 is movably installed in the placement frame 71 through a rotating shaft. The cleaning device 6 includes a mounting plate 61, a second slide block 62, a connecting frame 63, a synchronous belt drive mechanism 64, a lifting platform 65, a slide rod 66, a washing mechanism 67, and a displacement seat 68. There are two second slide blocks 62 and two connecting frames 63. The two second slide blocks 62 are installed on the top of the mounting plate 61. The two connecting frames 63 are installed on the top two sides of the mounting plate 61 respectively. The synchronous belt drive mechanism 64 is installed between the two connecting frames 63. The displacement seat 68 is slidably connected to the outer surface of the two second slide blocks 62. The lifting platform 65 is installed at one end of the displacement seat 68. The slide rod 66 is slidably connected to the end of the lifting platform 65 away from the displacement seat 68. The washing mechanism 67 is installed at the bottom end of the slide rod 66. The processing box 1 is divided into a cleaning area, a drying area, and an installation area by two partitions 4; Two partitions 4 are installed inside the processing box 1. A crusher 8 is installed on one side of the processing box 1. Three fans 11 are installed at equal intervals on one side of the inner wall of the processing box 1. A heater 13 and a baffle 12 are installed together between one of the partitions 4 and one side wall of the processing box 1. An inclined panel 10 is installed in the middle of the lower wall of the processing box 1. A recovery pipe 9 is installed at one end of the processing box 1. The heater 13 is located below the baffle 12, one end of the recovery pipe 9 is connected to the three fans 11 through the pipe, and the top of the inclined panel 10 is set as an inclined structure. A control panel 2 is installed in the middle of one end of the processing box 1, and a controller 3 is installed on one side of one end of the processing box 1. The controller 3 is electrically connected to the control panel 2.

[0023] As described above, the washing liquid and water are introduced into the upper part of the cleaning area in the treatment tank 1 according to a certain ratio, and heated by the heater 13. The heat is then passed through the baffle 12 to heat the water in the cleaning area. Plastic waste, which has been roughly washed to remove sand, metal and other foreign objects, is placed in the placement frame 71. The lifting platform 65 is started, and the lifting platform 65 drives the sliding rod 66 to move downward. The sliding rod 66 pushes the connecting plate 671 to move downward. The connecting plate 671 drives the limiting post 674 to move downward and insert into the corresponding two limiting tubes 72. Through the continuous pushing of the sliding rod 66, the limiting post 674 is inserted into the placement frame 71, and the limiting post 674 pushes the limiting tube 72 to move downward. The limiting tube 72 pushes the placement frame 71 downward and causes the spring 75 to contract. After the placement frame 71 enters the treatment tank 1, the motor 672 is started. The output end of the motor 672 drives the brush rod that is fixedly connected to it. Rotating 673 cleans the plastic waste through the brush rod 673. After cleaning, the lifting mechanism 65 raises the limit post 674, causing it to slide within the limit tube 72. The spring 75 then uses its elasticity to move the placement frame 71 upward out of the processing box 1. Subsequently, the synchronous belt drive mechanism 64 drives the displacement seat 68 to slide on the second slide 62, causing the lifting mechanism 65 to move the slide rod 66. The slide rod 66, through the washing mechanism 67 and the limit tube 72, moves the placement frame 71 and causes the limit plate 74 to slide on the first slide 14. After moving to the drying area, the lifting mechanism 65 moves the placement device 7 downward again, allowing the plastic waste to be inserted into the drying area within the processing box 1. The three fans 11 start, transferring the heat from the lower part of the cleaning area within the processing box 1 to the drying area within the processing box 1 through the recovery pipe 9, thereby accelerating the drying of the plastic waste. Example

[0024] refer to Figure 4 and Figure 5 As shown, the electric telescopic rod 76 is movably connected to the movable base plate 77 via a rotating shaft, and the two side limiting plates 74 are slidably connected to the two first sliding blocks 14 respectively.

[0025] As can be seen from the above, after the plastic waste has completed the cleaning and drying process, the synchronous belt drive mechanism 64 is started. This device drives the displacement seat 68 to move horizontally and linearly along the second slide seat 62 through the synchronous belt drive mechanism 64, and transports the placement frame 71 carrying the processed plastic waste to the installation area directly above the processing box 1. At this time, the two electric telescopic rods 76 installed at the bottom of the placement frame 71 are started synchronously, pushing the movable base plate 77 to rotate clockwise downward around one side hinge point, forming a stable V-shaped unloading channel. The plastic waste in the placement frame 71 slides smoothly down the channel under the action of gravity and falls into the chamber of the crusher 8 through the feed port of the crusher 8 for crushing and processing.

[0026] Preferably, the placement frame 71 is located below the brush handle 673.

[0027] As can be seen from the above, when the lifting platform 65 drives the sliding rod 66 to move the washing mechanism 67 downward as a whole, the brush rod 673 can vertically penetrate into the internal space of the placement frame 71. The placement frame 71 adopts an open frame structure, and its four side walls are set as mesh, which not only ensures the flow of cleaning liquid, but also provides an insertion channel for the brush rod 673. The surface of the brush rod 673 is embedded with high-density nylon bristles. When it penetrates into the placement frame 71, the bristles can form all-round contact with the plastic waste in the frame, and achieve deep cleaning through 360-degree rotation brushing. Example

[0028] refer to Figure 6 , Figure 7 and Figure 8 As shown, the synchronous belt drive mechanism 64 is installed together with the displacement seat 68, and one end of the slide rod 66 is installed together with the track inside the elevator 65; The washing mechanism 67 includes a connecting plate 671, a motor 672, and limiting posts 674. The motor 672 is installed at the top center of the connecting plate 671. The output end of the motor 672 passes through the bottom center of the connecting plate 671 and is equipped with a brush rod 673. There are two limiting posts 674, and the two limiting posts 674 are respectively fixedly connected to the two sides of the bottom of the connecting plate 671.

[0029] As can be seen from the above, when the lifting platform 65 is started, its driving slide rod 66 moves vertically downward. The slide rod 66 drives the connecting plate 671 to move downward synchronously, so that the limiting post 674 is inserted into the corresponding limiting tube 72 on both sides of the placement frame 71. As the slide rod 66 continues to press down, the limiting post 674 pushes the limiting tube 72 and the entire placement frame 71 to move downward against the elastic force of the spring 75 until the placement frame 71 is completely immersed in the cleaning fluid. At this time, the motor 672 is started, and its output end drives the brush rod 673 to rotate. Through mechanical brushing, the fine pollutants remaining on the surface of the plastic waste are removed, which improves the cleaning effect of the plastic waste.

[0030] Preferably, the two limiting posts 674 are movably inserted and connected within the two limiting tubes 72.

[0031] As can be seen from the above, by setting the limit post 674 and the limit tube 72 to be connected in an interlocking manner, the placement frame 71 can be driven to rise and fall.

[0032] Furthermore, this invention is designed for application in the recycling and treatment of heavily polluting waste generated during the production of thermal insulation composite materials. In actual operation, during the recycling and treatment of plastic waste, the washing liquid and water are first mixed according to a preset ratio and then injected into the upper part of the cleaning area of ​​the treatment tank 1. The mixture is heated by the heater 13, and the heat is evenly conducted to the water in the cleaning area through the baffle 12, so that the water temperature rises to a suitable range. At this time, the plastic waste that has been coarsely washed to remove large particles of impurities such as sand and metal is placed into the placement frame 71 to prepare for subsequent deep cleaning. Start the lifting platform 65, and its drive slide bar 66 moves vertically downward. The slide bar 66 drives the connecting plate 671 to move downward synchronously, so that the limiting post 674 is inserted into the corresponding limiting tube 72 on both sides of the placement frame 71. As the slide bar 66 continues to press down, the limiting post 674 pushes the limiting tube 72 and the entire placement frame 71 to move downward against the elastic force of the spring 75 until the placement frame 71 is completely immersed in the cleaning fluid. At this time, start the motor 672, and its output end drives the brush bar 673 to rotate, removing the fine pollutants remaining on the surface of the plastic waste through mechanical brushing. After cleaning, the control lift 65 reverses. During the upward movement of the slide bar 66, the limiting post 674 slides relative to the limiting tube 72. The spring 75 returns to its deformation and pushes the placement frame 71 to automatically rise outside the processing box 1. Then, the synchronous belt drive mechanism 64 is activated, which drives the displacement seat 68 to move horizontally along the second slide 62. Then, the placement frame 71 is moved laterally through the washing mechanism 67 and the limiting tube 72. During the displacement, the limiting plate 74 slides smoothly along the first slide 14 to ensure that the placement frame 71 is transferred to the top of the drying area. Upon reaching the drying area, the elevator 65 is activated again to lower the placement frame 71, placing the plastic waste in a specific position within the drying area. At this time, three fans 11 are turned on, and the residual heat accumulated at the bottom of the cleaning area is transported to the drying area through the recovery pipe 9, forming a hot air circulation system. The hot air evenly coats the surface of the plastic waste, accelerating moisture evaporation and significantly shortening the drying time. After drying is completed, the elevator 65 drives the placement frame 71 back to its initial height. Finally, the placement frame 71 is transferred to the installation area above the processing box 1 by the synchronous belt drive mechanism 64, and the two electric telescopic rods 76 are activated. Their output ends extend and push the movable base plate 77 to flip down around the hinge point to form an inclined unloading channel. The plastic waste falls automatically into the crusher 8 below through the feed port along the channel, completing the fully automated process from washing to crushing. This process achieves efficient cleaning and resource utilization of plastic waste through mechanical linkage and heat recovery technology. The washing stage uses immersion brushing to ensure thorough removal of pollutants, the drying stage uses waste heat recovery to reduce energy consumption, and finally, through crushing, plastic granules that meet the reuse standards are obtained, which significantly improves recycling efficiency and product quality.

[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
