[0026] The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0027] The utility model discloses a polypropylene raw material processing device, Figure 1 to Figure 3 As shown, it includes a processing device body 1. When polypropylene is produced, the recycled waste plastics will be crushed and used as polypropylene raw materials for producing new polypropylene materials, thereby realizing the recycling of resources. After the recycled waste plastics are crushed, they will contain a lot of impurities. In order to facilitate the processing of subsequent processes, a processing device body 1 is provided, and the impurities in the crushed plastics are processed in the processing device body 1.

[0028] Ginseng Figure 2 and Figure 6As shown, a first filter plate 2 and a second filter plate 6 are installed in the processing device body 1, and the first filter plate 2 is arranged above the second filter plate 6. A first filter plate 2 and a second filter plate 6 are installed in the processing device body 1, and impurities in the crushed plastic particles are processed by the first filter plate 2 and the second filter plate 6. The first filter plate 2 is arranged above the second filter plate 6, and the first filter plate 2 is used to process larger impurities and metal impurities in the plastic particles, and the second filter plate 6 is used to process smaller impurities in the plastic particles.

[0029] Ginseng Figure 3 to Figure 6 As shown, the first filter plate 2 is provided with multiple groups of first through holes 3 in an annular manner, and multiple magnetic rings 4 are fixedly connected to the lower end of the first filter plate 2. The multiple magnetic rings 4 are arranged between the multiple groups of first through holes 3, and the lower ends of the multiple magnetic rings 4 are provided with magnetic strips 5. Multiple groups of first through holes 3 are provided in an annular manner on the first filter plate 2, and the first through holes 3 are set to have a larger aperture so that plastic particles can pass through. The first through holes 3 are arranged in groups in an annular manner, in order to facilitate the fixed connection of the magnetic ring 4 at the lower end of the first filter plate 2, and the magnetic ring 4 is arranged between each adjacent group of first through holes 3, so that the metal impurities in the plastic particles flowing through the first through holes 3 can be adsorbed by the magnetic ring 4, thereby separating the plastic particles from the metal impurities. A magnetic strip 5 is arranged at the lower end of the magnetic ring 4, and the metal impurities in the plastic particles can be filtered again by the magnetic strip 5 to ensure that the metal impurities in the plastic particles are cleaned.

[0030] It should be noted that there is a sufficient distance between two adjacent magnetic strips 5 to ensure that the plastic particles flow down smoothly and to prevent the plastic particles from being stuck between the two adjacent magnetic strips 5 .

[0031] Ginseng Figure 3 to Figure 6 As shown, a plurality of second through holes 7 are provided on the second filter plate 6. The plastic particles flow to the second filter plate 6 through the first through holes 3 on the first filter plate 2. A plurality of second through holes 7 are provided on the second filter plate 6. The aperture of the second through holes 7 is small, which can ensure that the plastic particles do not pass through the second through holes 7. Thus, the plastic particles are intercepted by the second through holes 7, and the smaller impurities contained in the plastic particles are filtered, so that the smaller impurities in the plastic particles can flow to the bottom of the second filter plate 6 through the second through holes 7.

[0032] Ginseng Figure 3 and Figure 6As shown, the upper cover 9 is connected to the upper cover of the processing device body 1, and the first bearing 10 is installed on the upper cover 9. The second bearing 11 is installed on the first filter plate 2 and the second filter plate 6. The rotating shaft 12 is sleeved in the first bearing 10 and the second bearing 11, and the upper end of the rotating shaft 12 is installed with a motor 13. Since the upper cover 9 is connected to the processing device body 1, the upper cover 9 on the processing device body 1 can be disassembled, so that the upper cover 9 can be disassembled. Since the first bearing 10 is installed on the upper cover 9, the second bearing 11 is installed on the first filter plate 2 and the second filter plate 6, the rotating shaft 12 is sleeved in the first bearing 10 and the second bearing 11, so that the rotating shaft 12 can rotate under the action of the first bearing 10 and the second bearing 11. A motor 13 is installed on the upper end of the rotating shaft 12, and the rotating shaft 12 can be driven to rotate by the motor 13.

[0033] Preferably, the motor 13 is a low-speed motor, so that the motor (13) drives the rotating shaft 12 to rotate at a lower speed.

[0034] Ginseng Figure 3 and Figure 4 As shown, a pair of first stirring impellers 14 and a pair of second stirring impellers 16 are installed on the side wall of the rotating shaft 12, and the pair of first stirring impellers 14 are both arranged above the first filter plate 2, and the pair of second stirring impellers 16 are both arranged above the second filter plate 6. Since the pair of first stirring impellers 14 and the pair of second stirring impellers 16 are both installed on the rotating shaft 12, the first stirring impellers 14 and the second stirring impellers 16 can be driven to rotate when the rotating shaft 12 rotates. Since the first stirring impeller 14 is arranged above the first filter plate 2, the rotation of the first stirring impeller 14 can drive the plastic particles on the first filter plate 2 to rotate, so that the plastic particles quickly pass through the first through hole 3 and flow to the second filter plate 6. Since the second stirring impeller 16 is arranged above the second filter plate 6, the rotation of the second stirring impeller 16 can drive the plastic particles on the second filter plate 6 to rotate, so that the smaller impurities in the plastic particles quickly pass through the support ring 8 and flow to the bottom of the processing device body 1.

[0035] Ginseng Figure 3 and Figure 6 As shown, a pair of support rings 8 are fixedly connected to the inner side wall of the processing device body 1, and the first filter plate 2 and the second filter plate 6 are respectively installed on the pair of support rings 8. By fixing a pair of support rings 8 on the inner side wall of the processing device body 1, the first filter plate 2 and the second filter plate 6 can be installed through the pair of support rings 8. At the same time, the first filter plate 2 and the second filter plate 6 are supported by the support rings 8, so that the first filter plate 2 is easily removed from the processing device body 1, thereby facilitating the cleaning and maintenance of the first filter plate 2.

[0036] Ginseng Figure 4 As shown, the lower ends of the front and rear side walls of the first stirring impeller 14 are fixedly connected with crushing knives 15. By fixing the crushing knives 15 at the lower ends of the front and rear side walls of the first stirring impeller 14, when the first stirring impeller 14 drives the crushing knives 15 to rotate, the plastic particles can be broken up so that the agglomerated plastic particles can pass through the first through hole 3.

[0037] Ginseng Figure 1 to Figure 3 as well as Figure 6 As shown, a first discharge port 17 is provided on the side wall of the processing device body 1, and the position of the first discharge port 17 corresponds to the position of the first filter plate 2. A gate valve 19 is installed on the outer side wall of the processing device body 1, and the gate valve 19 is arranged outside the first discharge port 17. By providing the first discharge port 17 on the side wall of the processing device body 1, the impurities and plastic particles intercepted by the first filter plate 2 can be cleaned through the first discharge port 17 to avoid affecting the use of the device. The gate valve 19 is used to control the opening and closing of the first discharge port 17, so as to close the first discharge port 17 when filtering the plastic particles.

[0038] Ginseng Figure 1 to Figure 3 as well as Figure 6 As shown, a second discharge port 18 is provided on the side wall of the processing device body 1, and the position of the second discharge port 18 corresponds to the position of the second filter plate 6. A feed trough 20 is fixedly connected to the outer side wall of the processing device body 1, and the feed trough 20 is arranged outside the second discharge port 18. By installing the second discharge port 18 on the side wall of the processing device body 1, the plastic particles on the second filter plate 6 can be discharged through the second discharge port 18. The feed trough 20 is arranged outside the second discharge port 18, and the lower side wall of the feed trough 20 is inclined, so that the plastic particles can flow out through the feed trough 20.

[0039] Ginseng Figure 1 and Figure 6 As shown, a discharge pipe 21 is installed at the lower end of the processing device body 1, and a discharge cover 22 is connected to the upper cover of the discharge pipe 21. Smaller impurities filtered by the second filter plate 6 will fall to the bottom of the processing device body 1, and will be discharged through the discharge pipe 21 at the bottom of the processing device body 1, and the discharge cover 22 will control the switch of the discharge pipe 21.

[0040] Ginseng Figure 1 and Figure 6 As shown, a feed port 23 is installed on the upper cover 9, and the crushed plastic particles are added into the processing device body 1 through the feed port 23 for impurity processing.

[0041] When in use, the motor 13 is started to drive the rotating shaft 12 to rotate, and the crushed plastic particles are added into the processing device body 1 through the feed port 23, and the plastic particles will fall on the first filter plate 2. When the rotation of the rotating shaft 12 drives the first stirring impeller 14 to rotate, the first stirring impeller 14 will drive the plastic particles on the first filter plate 2 to rotate, so that the plastic particles on the first filter plate 2 fall through the first through hole 3. When the plastic particles fall from the first through hole 3, they will pass through the magnetic ring 4 and the magnetic strip 5. The magnetic ring 4 and the magnetic strip 5 can absorb the metal impurities in the plastic particles, so that the plastic particles and the metal impurities are separated. After the plastic particles passing through the first through hole 3 fall on the second filter plate 6, when the rotating shaft 12 rotates to drive the second stirring impeller 16 to rotate, the second stirring impeller 16 will drive the plastic particles on the second filter plate 6 to rotate, and the smaller impurities in the plastic particles will pass through the second through hole 7 and fall at the bottom of the processing device body 1. Driven by the second stirring impeller 16, the plastic particles are discharged from the second discharge port 18.

[0042] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0043] The utility model filters the crushed plastic particles through the first filter plate. When the plastic particles pass through the first filter plate, the magnetic ring arranged at the lower end of the first filter plate will filter the metal impurities in the plastic particles, and the second filter plate will filter the impurities with smaller particle sizes in the plastic particles, thereby reducing the impurities in the plastic particles and preventing the impurities from affecting the processing of the plastic particles in subsequent processes.
