[0002] With technological advancements and changing market demands, the application fields of polypropylene have been continuously expanding, evolving from a single variety to multiple categories such as homopolymers, copolymers, and impact-modified products. To meet the needs of different application fields, polypropylene manufacturers are constantly developing new technologies and processes, such as thin-wall technology, micro-foaming technology, low-odor technology, fiber reinforcement technology, and the nucleating agent revolution, which have continuously improved the performance of polypropylene and covered all aspects of its application, from daily necessities to high-end technology products.

[0003] However, during the use of polypropylene (PP) meltblown special materials, it is inevitable that some materials will spill onto the ground or be mixed with impurities. Such losses directly result in the ineffective use of valuable raw materials, causing significant resource waste. Since impurity-containing polypropylene (PP) meltblown special materials cannot be directly recycled, they need to be processed through impurity separation to meet the requirements for secondary use and improve resource utilization.

A hollow shell is installed on the upper surface of the support frame. The hollow shell is connected to the outer surface of the hollow column. Multiple sieve openings are opened on the outer surface of the hollow column. A connecting shaft is installed inside the hollow column. A conveying paddle is provided on the outer surface of the connecting shaft. A fixing plate is installed on the outer surface of the hollow column. A motor is installed on the outer surface of the fixing plate. The output end of the motor is connected to the right end of the connecting shaft.

[0006] As a further improvement of this utility model: the outer surface of the hollow column is provided with a discharge port B, a guide plate is installed on the outer surface of the hollow column, and a collection frame is placed below the guide plate.

[0007] As a further improvement of this utility model: the outer surface of the hollow column is provided with a discharge port A, and a waste frame is placed below the discharge port A.

[0008] As a further embodiment of this utility model: a material inlet is provided on the outer surface of the hollow shell, the bottom surface of the material inlet is connected to a hollow column, and two fans are installed inside the hollow shell.

[0009] As a further improvement of this utility model: a dust collection device is provided on the left side of the support frame, a collection box is installed inside the dust collection device, and a handle is installed on the outer surface of the collection box.

[0010] As a further improvement of this utility model: the input end of the vacuum cleaner is connected to an extension tube, and the end of the extension tube away from the vacuum cleaner is connected to an adapter.

[0011] As a further embodiment of this utility model: a control board is installed on the outer surface of the support frame, a speed adjustment knob is installed on the outer surface of the control board, and a switch is installed on the outer surface of the control board.

[0012] Compared with the prior art, the beneficial effects of this utility model include:

[0013] This invention utilizes a hollow outer shell and a hollow column with sieve openings to create a highly efficient separation space. When polypropylene (PP) meltblown special material containing impurities enters the device, the sieve openings quickly achieve preliminary separation of the material from the impurities, avoiding the inefficiency and high cost of manual sorting and reducing labor consumption. A motor-driven connecting shaft rotates the conveyor paddle, ensuring continuous and stable material transport, guaranteeing the continuity of the recycling process, preventing processing stagnation caused by material accumulation, effectively improving recycling efficiency, and allowing polypropylene (PP) meltblown special material that might otherwise be discarded to be reused.

[0021] An embodiment of the present invention is shown in conjunction with the accompanying drawings.

[0022] An energy-saving recycling device for polypropylene (PP) meltblown special material includes a support frame 1 and a hollow column 3. A hollow shell 2 is installed on the upper surface of the support frame 1, and the hollow shell 2 is connected to the outer surface of the hollow column 3. Multiple screens 4 are opened on the outer surface of the hollow column 3. A connecting shaft 6 is installed inside the hollow column 3, and a conveying paddle 20 is set on the outer surface of the connecting shaft 6. A fixing plate 7 is installed on the outer surface of the hollow column 3, and a motor 5 is installed on the outer surface of the fixing plate 7. The output end of the motor 5 is connected to the right end of the connecting shaft 6. The hollow shell 2 and the hollow column 3 with screens 4 cooperate with each other to form a high-efficiency separation space. When polypropylene (PP) meltblown special material containing impurities enters the device, the screens 4 can quickly achieve preliminary separation of the material from the impurities, avoiding the inefficiency and high cost of manual sorting and reducing labor consumption.

[0023] In this embodiment, a discharge port B12 is provided on the outer surface of the hollow column 3, and a guide plate 15 is installed on the outer surface of the hollow column 3. A collection frame 14 is placed below the guide plate 15. The guide plate 15 can accurately drop the material into the collection frame 14 to avoid scattering it on the ground.

[0024] In this embodiment, a discharge port A11 is provided on the outer surface of the hollow column 3, and a waste frame 13 is placed below the discharge port A11. Impurities fall into the interior of the hollow column 3 through the sieve 4 and are collected and processed in the waste frame 13 through the discharge port A11.

[0025] In this embodiment, a feeding port 8 is provided on the outer surface of the hollow shell 2. The bottom surface of the feeding port 8 is connected to a hollow column 3. Two fans 23 are installed inside the hollow shell 2. During screening, the fans 23 will blow up smaller dust and impurities, which will be convenient for the subsequent dust extraction device 19 to extract these dust.

[0026] In this embodiment, a dust collection device 19 is provided on the left side of the support frame 1. A collection box 21 is installed inside the dust collection device 19. A handle 22 is installed on the outer surface of the collection box 21. Impurities can be sucked into the collection box 21 by the dust collection device 19, and the collection box 21 can be taken out by the handle 22 for easy subsequent cleaning.

[0027] In this embodiment, the input end of the vacuum cleaner 19 is connected to an extension tube 9, and the end of the extension tube 9 away from the vacuum cleaner 19 is connected to an adapter 10. The adapter 10 penetrates the hollow outer shell 2, so that the fan 23 can blow up smaller dust and impurities and suck them into the collection box 21 through the vacuum cleaner 19.

[0028] In this embodiment, a control board 16 is installed on the outer surface of the support frame 1, a speed adjustment knob 17 is installed on the outer surface of the control board 16, and a switch 18 is installed on the outer surface of the control board 16.

[0029] Working principle: Polypropylene (PP) meltblown special material containing impurities is fed into the hollow column 3 through the feed port 8. The motor 5 is started, and its output end drives the connecting shaft 6 to rotate, which in turn causes the conveying paddle 20 on the connecting shaft 6 to start running, pushing the material to move inside the hollow column 3. The material is screened using the sieve 4 on the outer surface of the hollow column 3. Impurities fall from the sieve 4 into the hollow shell 2 during movement. The screened polypropylene (PP) meltblown special material particles are guided by the guide plate 15 inside the hollow column 3 and fall from the discharge port B12 into the collection box 14 to complete the recycling. Impurities are discharged from the discharge port A11 and fall into the waste box 13 below for centralized processing. At the same time as screening, the fan 23 blows up small dust and impurities, which can be sucked into the collection box 21 by the dust suction device 19. The collection box 21 can be taken out by the handle 22 for subsequent cleaning. The operator can adjust the speed of the motor 5 by the speed adjustment knob 17 on the control panel 16 to control the screening and conveying speed. The start and stop control of the device is realized by the switch 18 to ensure that the entire recycling process is efficient and stable.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
