[0013] A process for separating raw materials for recycling waste plastics comprises the following steps: Step 1: Crushing. Metal and scrap materials enter the crushing shell from the feed pipe. The first motor controls the central shaft to rotate, and the crushing blocks crush the materials to make the particles uniform, which is convenient for subsequent separation.

After the material is crushed, it is discharged from the discharge valve into the separation mechanism, and the material is blown by air through the separation mechanism to achieve the effect of material separation.

[0014] The present invention provides a raw material separation device for recycling waste plastics. It has the following beneficial effects: 1. The raw material separation device for recycling waste plastics is designed with a crushing device. Metal and plastic enter the crushing shell from the feed pipe. The first motor controls the rotation of the central shaft to make the crushing block crush the material, thereby crushing the material, thereby achieving the effect of uniform material particles, breaking it into smaller particles or fragments for better subsequent separation. During the crushing process, the material particles are scattered. When impurities remain on the surface of the material, the material will be adsorbed on the inner wall of the equipment. The central shaft controls the rotation of the scraping mechanism to peel off the impurities on the inner wall of the equipment, thereby reducing material residue and allowing the material to participate more in the crushing process, making its material particles uniform. Secondly, the stirring mechanism rotates with the central shaft, and the bottom of the crushing shell adopts a conical structure. When the material falls, the friction between the materials may cause the materials to be fixed, thereby affecting the material falling effect. The material falling speed is controlled by the discharge valve to keep the material falling evenly, avoiding excessive falling flow that affects the subsequent separation effect, and finally the plastic and metal are separated by the separation mechanism.

[0015] 2. The raw material separation device for recycling waste plastics is designed with a stirring mechanism. After the material is crushed, it flows to the side of the discharge valve. The discharge valve controls the material's descending speed to keep the material descending at a uniform speed, providing operating time for the separation mechanism. Therefore, the stirring bracket is controlled to rotate by the central shaft to stir the material at the bottom of the inner wall of the separation shell, thereby promoting the flow of material and avoiding friction between materials that may cause the material to be fixed inside the equipment, thereby preventing the equipment from being blocked. The extension frame is set on the outside of the stirring bracket to increase the stirring range of the components and improve the stirring efficiency. The square plate is made of rubber, which slows down the impact of the falling material and avoids the impact of the material on the components.

[0016] 3. The raw material separation device for recycling waste plastics is designed with a separation mechanism, and the material is discharged from the inside of the discharge valve. The interior of the separation shell adopts a flow space with two-end pipes, one end is wider and the other end is narrower. The first fan controls the wind force. When the material descends, the wind blows the plastic particles in the material, causing the debris to flow to the narrower side and the metal debris to flow to the wider side, thereby realizing the separation operation of metal and plastic. Secondly, the electric push rod is used to control the magnetic plate to move toward the side of the soft film. The soft film has good toughness and is convenient for the extension of the component. It extends to the inside of the separation shell through the magnetic plate, thereby guiding the flow direction of the metal debris by magnetic attraction, thereby further improving the separation operation of the material, thereby further improving the separation accuracy. The metal debris is adsorbed on the surface of the magnetic plate, and the electric push rod is used to control the magnetic plate for recycling. The soft film is used to block the metal debris, thereby facilitating the flow of metal debris adsorbed on the surface of the soft film, avoiding waste of resources, and thus guiding repeated operations.

[0017] 4. The raw material separation device for recycling waste plastics is designed with a dust reduction mechanism. After the material inside the crushing device is dried by the drying device, the surface of the material is kept dry to prevent the surface of the material from getting wet and affecting the flow of the material inside the equipment. Therefore, the crushing device crushes the dried material, resulting in a large amount of dust from the material. The dust accumulates inside the equipment, which can easily cause the dust to block the components and increase the internal material crushing resistance. Secondly, excessive dust accumulation can easily lead to dust explosion and easily affect the heat dissipation effect of the equipment itself. The second fan generates wind power to absorb the dust inside the equipment and flow it to the outside, thereby achieving the effect of dust reduction. In the process of guiding the dust flow, the grille pipe blocks the flow of internal particles to prevent the particles from flowing outward.

[0018] 5. The raw material separation device for recycling waste plastics is designed with a drying device. A hot air flow is generated by the dryer. The hot air flow flows through the discharge pipe to the inside of the crushing shell, so as to dry the inside of the equipment, thereby keeping the inner wall of the equipment dry, reducing the adhesion of materials, preventing materials from remaining inside the equipment, and avoiding impurities remaining during the material crushing process or on the surface of the material from adhering to the inner wall of the equipment, preventing corrosion and pollution to the equipment, reducing material adhesion, and avoiding affecting the heat dissipation effect of the equipment itself. The grid plate plays the role of blocking material particles to prevent debris from entering the discharge pipe during the crushing process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution: a raw material separation device and process for recycling waste plastics, comprising a crushing device 1, a first motor 5 fixedly connected to the middle of the top of the crushing device 1, a drying device 3 fixedly connected to the upper side of the outside of the crushing device 1, a dust reduction mechanism 2 fixedly connected to the side of the top of the crushing device 1 away from the drying device 3, and a frame 4 fixedly connected to the inclined portion of the outside of the crushing device 1; The crushing device 1 includes a crushing shell 11, the top of the crushing shell 11 is rotatably connected to the central rotating shaft 12, the output end of the first motor 5 is fixedly connected to the top of the central rotating shaft 12, the outer side of the central rotating shaft 12 is fixedly connected to the connecting end 19, the outer side of the connecting end 19 is fixedly connected to the crushing block 13, the two ends outside the connecting end 19 are fixedly connected to the scraping mechanism 15, the side of the outside of the central rotating shaft 12 away from the first motor 5 is fixedly connected to the stirring mechanism 16, the outer side of the crushing shell 11 is fixedly connected to the feed pipe 14, the bottom of the crushing shell 11 is fixedly connected to the discharge valve 17, and the bottom of the discharge valve 17 is fixedly connected to the separation mechanism 18. Metal and plastic enter the pulverizing shell 11 from the feed pipe 14, and the first motor 5 controls the central rotating shaft 12 to rotate, so that the crushing block 13 breaks the material, thereby crushing the material, thereby achieving the effect of uniform material particles, breaking it into smaller particles or fragments for better subsequent separation. During the pulverizing process, the material particles are scattered. When impurities remain on the surface of the material, the material will be adsorbed on the inner wall of the equipment. The central rotating shaft 12 controls the rotation of the scraping mechanism 15 to peel off the impurities on the inner wall of the equipment, thereby reducing material residue and allowing the material to participate more in the crushing process, making the material particles uniform. Secondly, the stirring mechanism 16 rotates with the central rotating shaft 12. The bottom of the pulverizing shell 11 adopts a conical structure. When the material descends, the friction between the materials may cause the materials to be fixed, thereby affecting the material descent effect. The material descent speed is controlled by the discharge valve 17 to keep the material descending evenly, avoiding excessive descending flow that affects the subsequent separation effect. Finally, the plastic and metal are separated by the separation mechanism 18.

[0023] The scraping mechanism 15 includes a scraping bracket 151, with a connecting rod 152 fixedly connected between the opposing surfaces of the scraping bracket 151. A scraping column 153 is rotatably connected to the outer side of the connecting rod 152. The two ends of the outer side of the connecting rod 152 are fixedly connected to the connecting frame 154, and the outer side of the connecting frame 154 is fixedly connected to the guide plate 155. The central rotating shaft 12 drives the scraping bracket 151 to rotate, and the scraping column 153 rubs against the inner wall of the crushing shell 11, thereby achieving the effect of stripping the material, reducing the amount of material remaining on the inner wall of the equipment, and keeping the interior of the equipment clean. During the friction rotation of the scraping column 153, the scraped material is prompted to move along with the guide plate 155, and the guide plate 155 guides the material to move toward the crushing block 13, thereby achieving the effect of guiding material separation, improving the crushing efficiency, and enhancing the material crushing effect.

[0024] The stirring mechanism 16 includes a rotating column 161, a stirring bracket 162 is fixedly connected to the outside of the rotating column 161, a square plate 163 is fixedly connected to the top of the stirring bracket 162, and an extension bracket 164 is fixedly connected to the outer inclined side of the stirring bracket 162. After being crushed, the material flows to the side of the discharge valve 17. The discharge valve 17 controls the material's descent speed, so that the material maintains a uniform descent speed, providing operating time for the separation mechanism 18. Therefore, the stirring bracket 162 is controlled to rotate by the central rotating shaft 12 to stir the material at the bottom of the inner wall of the grinding shell 11, thereby promoting material flow and preventing friction between the materials from causing the materials to be fixed inside the equipment and preventing the equipment from being blocked. The extension bracket 164 is arranged on the outside of the stirring bracket 162 to increase the stirring range of the components and improve the stirring efficiency. The square plate 163 is made of rubber, which slows down the impact of the falling material and prevents the material from impacting the components.

[0025] The separation mechanism 18 includes a separation shell 181, one side of the outside of the separation shell 181 is fixedly connected to the first fan 182, one side of the outside angle of the separation shell 181 is fixedly connected to the square shell 183, the outer side of the square shell 183 is fixedly connected to the electric push rod 184, one side of the outside of the electric push rod 184 is fixedly connected to the magnetic plate 185, and the inner wall of the square shell 183 away from the electric push rod 184 is fixedly connected to the soft rubber film 186. The material is discharged from the inside of the discharge valve 17. The separation shell 181 adopts a two-end pipe flow space, one end is wider and the other end is narrower. The first fan 182 controls the wind force. When the material descends, the wind blows the plastic particles in the material, causing the debris to flow to the narrower side and the metal debris to flow to the wider side, thereby realizing the separation operation of metal and plastic. Secondly, the electric push rod 184 controls the magnetic plate 185 to move toward the side of the soft film 186. The soft film 186 has good toughness and is convenient for the extension of the component. It extends to the inside of the separation shell 181 through the magnetic plate 185, thereby guiding the flow direction of the metal debris by magnetic attraction, thereby further improving the separation operation of the material, thereby further improving the separation accuracy. The metal debris is adsorbed on the surface of the magnetic plate 185, and the electric push rod 184 controls the magnetic plate 185 for recovery. The soft film 186 blocks the metal debris, thereby facilitating the flow of metal debris adsorbed on the surface of the soft film 186, avoiding resource waste, and thus guiding repeated operations.

[0026] The second embodiment, based on the first embodiment, see Figures 5 and 6As shown, the dust suppression mechanism 2 includes a dust suppression base plate 21, a ring frame 22 fixedly connected to the top of the dust suppression base plate 21, a second fan 23 plugged into the inner side of the ring frame 22, a grille pipe 24 fixedly connected to the bottom of the dust suppression base plate 21, a second motor 26 fixedly connected to the bottom of the grille pipe 24, and a friction mechanism 25 fixedly connected to the bottom of the inner wall of the grille pipe 24. After the material inside the pulverizing device 1 is dried by the drying device 3, the surface of the material is kept dry to prevent the surface from getting wet and thus affecting the flow of the material inside the device. Therefore, the pulverizing device 1 pulverizes the dried material, resulting in a large amount of dust. The dust accumulates inside the device, which can easily cause dust to clog components and increase the resistance to internal material crushing. In addition, excessive dust accumulation can easily lead to dust explosion and affect the heat dissipation effect of the device itself. The second fan 23 generates wind force to absorb the dust inside the device, causing it to flow outward, thereby achieving the dust suppression effect. In the process of guiding the dust flow, the grille pipe 24 blocks the flow of internal particles and prevents the particles from flowing outward.

[0027] The friction mechanism 25 includes a connecting shaft 251, with an external post 252 fixedly connected to the outside of the connecting shaft 251. An external bracket 253 is fixedly connected to the outside of the external bracket 252. A friction block 254 is fixedly connected to one side of the external bracket 253. A second motor 26 controls the rotation of the connecting shaft 251, which in turn controls the rotation of the friction block 254 via the external bracket 253. This causes the friction block 254 to rub against the holes in the grille tube 24, removing impurities adhering to the surface of the component through friction. This prevents dust from clogging the component after prolonged operation, preventing dust flow and maintaining normal operation of the equipment.

[0028] The third embodiment, based on the first and second embodiments, see Figures 7 to 10 As shown, the drying device 3 includes a dryer 31, a discharge pipe 32 fixedly connected to one side of the outside of the dryer 31, a grille plate 33 fixedly connected to the bottom of the inner wall of the discharge pipe 32, and a rotating mechanism 34 fixedly connected to the top of the inner wall of the discharge pipe 32. The dryer 31 generates a hot air flow, which flows into the interior of the pulverizing shell 11 through the discharge pipe 32, thereby drying the interior of the equipment, thereby keeping the inner wall of the equipment dry, reducing the adhesion of materials, preventing materials from remaining inside the equipment, and preventing impurities remaining during the material pulverization process or on the surface of the materials from adhering to the inner wall of the equipment, thereby preventing corrosion and contamination of the equipment, reducing material adhesion, and avoiding affecting the heat dissipation effect of the equipment itself. The grille plate 33 acts as a barrier to material particles, preventing debris from entering the discharge pipe 32 during the pulverization process.

[0029] The rotating mechanism 34 includes a connecting shaft 341, the outer side of which is rotatably connected to a cylindrical housing 342. A paddle 343 is fixedly connected to the outer side of the cylindrical housing 342. A rotating bracket 344 is fixedly connected to both sides of the outer side of the cylindrical housing 342. A cylindrical grinding block 345 is fixedly connected to the outer side of the rotating bracket 344 away from the cylindrical housing 342. A cleaning mechanism 346 is fixedly connected to the bottom of the rotating bracket 344. When airflow impacts the paddle 343, the rotating bracket 344 drives the cylindrical grinding block 345 to rub against the inner wall of the discharge pipe 32, thereby cleaning dust or some particles. The airflow drives the dust and particles through the grille plate 33 and into the interior of the device, thereby cleaning impurities, preventing impurity accumulation from affecting the airflow effect, and maintaining smooth airflow within the device.

[0030] The cleaning mechanism 346 includes a sliding rod 3461, the outer side of which is slidably connected to the bottom of the rotating bracket 344. A spring bar 3463 is sleeved on the outer side of the sliding rod 3461, and a silicone ball 3462 is fixedly connected to one side of the outer portion of the sliding rod 3461. During the rotation of the rotating bracket 344, the silicone ball 3462 is squeezed by the reaction of the grille plate 33, causing the silicone ball 3462 to drive the sliding rod 3461 to squeeze the spring bar 3463, thereby accumulating kinetic energy. During the rotation process, after controlled contact with the grille plate 33, the spring rebound causes the silicone ball 3462 to impact the holes in the grille plate 33, thereby clearing out clogged particles and preventing them from clogging the holes and affecting airflow.

[0031] A process for separating raw materials for recycling waste plastics comprises the following steps: Step 1: Crushing: metal and scrap materials enter the crushing shell 11 from the feed pipe 14. The first motor 5 controls the central shaft 12 to rotate, and the crushing block 13 crushes the materials to make the particles uniform, which is convenient for subsequent separation. Step 2: Drying: The dryer 31 generates a hot air flow that enters the grinding shell 11 to dry the particles in the grinding process, preventing the material from being over-wetted and reducing the material from sticking to the inner wall of the equipment, thus facilitating the flow of the material. Step 3: dust reduction. The drying device 3 dries the inside of the pulverizing device 1, so that a large amount of smoke and dust is generated during the pulverizing process of the material by the pulverizing device 1. The smoke and dust inside the pulverizing device 1 is collected by the dust reduction mechanism 2, thereby achieving the purpose of dust reduction. Step 4: separation. After the material is crushed, it is discharged from the discharge valve 17 into the separation mechanism 18. The separation mechanism 18 blows the material with air to achieve the purpose of separating the material.

[0032] During use, the material enters the grinding shell 11 from the feed pipe 14, and a drying device 3 is set outside the grinding shell 11. After the material enters the equipment, considering that there may be impurities, grease, water vapor, etc. on the surface of the material, when the first motor 5 controls the central shaft 12 to rotate, the crushing block 13 crushes the material, thereby achieving the effect of uniformly crushing the material particles and breaking them into smaller particles or fragments for better subsequent separation. After the material is dried by the drying device 3, the particles are reduced from adhering to the inner wall of the equipment after the material is crushed, preventing the material from remaining inside the equipment and avoiding the material crushing process or on the surface of the material. The residual impurities adhere to the inner wall of the equipment to prevent corrosion and pollution to the equipment, reduce material adhesion, and avoid affecting the heat dissipation effect of the equipment itself. In the process of reducing material adhesion by drying the material, the material dust increases in the process of crushing the material. If the dust is not cleaned in time, the dust accumulates inside the equipment, which can easily cause the dust to block the components and increase the internal material crushing resistance. Secondly, too much dust accumulation can easily lead to dust explosion and easily affect the heat dissipation effect of the equipment itself, so as to keep the inside of the equipment clean and reduce safety hazards during operation. After the material is crushed, it flows to the side of the discharge valve 17 and passes through the discharge valve 1 7. Control the material flow rate to keep the material flowing at a uniform speed, prevent the material from falling too much and affecting the operation effect, provide operation time for the separation mechanism 18, the material enters the separation mechanism 18, and the separation shell 181 adopts a two-end pipe flow space, one end is wider and the other end is narrower. The first fan 182 controls the wind force. When the material falls, the wind blows the plastic particles in the material, so that the debris flows to the narrower side and the metal debris flows to the wider side, thereby realizing the separation of metal and plastic. The electric push rod 184 controls the magnetic plate 185 to move to the side of the soft film 186, and the soft film 1 86 has good toughness, which is convenient for component extension. It extends to the inside of the separation shell 181 through the magnetic plate 185, thereby guiding the flow direction of metal debris through magnetic attraction, thereby further improving the separation operation of the material, thereby further improving the separation accuracy. The metal debris is adsorbed on the surface of the magnetic plate 185, and the magnetic plate 185 is controlled by the electric push rod 184 for recycling. The metal debris is blocked by the soft film 186, thereby facilitating the flow of metal debris adsorbed on the surface of the soft film 186, avoiding waste of resources, and guiding repeated operations. Collection buckets are placed on both sides of the separation shell 181 to collect materials during the separation process.
