DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] In the embodiment, from Figures 1-5Provided is a dust removal and purification device for processing medical plastic particles. The utility model includes a processing table 1. Inside the processing table 1, there is a fixedly connected stirring barrel 2. Outside the stirring barrel 2, there is a fixedly connected connecting cylinder 3. On the top of the processing table 1, there is a fixedly connected fan 4. On the top of the processing table 1, there is a filter box 5 fixedly connected to the air inlet of the fan 4. Inside the filter box 5, there is a fixedly connected filter plate 6. Inside the filter box 5, there is a slidably connected scraper 7 that abuts against the filter plate 6. Inside the filter box 5, there is an air inlet pipe 8 extending between the connecting cylinder 3 and the stirring barrel 2. Outside the air inlet pipe 8, there is a dust suction member 9. On the top of the processing table 1, there is a fixedly connected mounting frame 10. Inside the mounting frame 10, there is a rotatably connected hydraulic rod 11. The output end of the hydraulic rod 11 is fixedly connected to a stirring member 12 that is rotatably connected to the inner wall of the stirring barrel 2.

[0027] When pouring plastic particles into the stirring barrel 2 for stirring, the plastic dust contained in the plastic particles is lifted. Start the fan 4, so that the dust inside the stirring barrel 2 enters the inside of the connecting cylinder 3 through the stirring barrel 2, and enters the air inlet pipe 8 through the dust suction member 9, so that the dust enters the inside of the filter box 5 and is filtered by the filter plate 6. When the dust adheres to the surface of the filter plate 6 and blocks the filter plate 6, the scraper 7 scrapes the dust on the surface of the filter plate 6. At the same time, the dust inside the filter box 5 is scraped out of the filter box 5. When the stirring member 12 rotates on the inner wall of the stirring barrel 2, the plastic particles adhering to the inner wall of the stirring barrel 2 are scraped off, and at the same time, the plastic particles are stirred evenly.

[0028] Specifically, referring to Figure 2 , a through hole is opened inside the stirring barrel 2. Outside the stirring member 12, there is a fixedly connected barrel cover 13 that contacts the stirring barrel 2.

[0029] In this embodiment, after the plastic particles inside the stirring barrel 2 are stirred, the dust enters the inside of the connecting cylinder 3 through the through hole. The barrel cover 13 prevents the plastic particles from spilling out from the top of the stirring barrel 2 during the stirring process, causing waste of materials.

[0030] Specifically, referring to Figure 2 , outside the hydraulic rod 11, there is a fixedly connected first gear 14. On the top of the mounting frame 10, there is a rotatably connected second gear 15 that meshes with the first gear 14. Inside the mounting frame 10, there is a fixedly connected first motor 16 whose output shaft is fixedly connected to the central shaft of the second gear 15.

[0031] In this embodiment, start the first motor 16. The first motor 16 drives the second gear 15 to rotate, so that the first gear 14 rotates, thereby driving the hydraulic rod 11 to rotate, so that the stirring member 12 stirs the plastic particles inside the stirring barrel 2 evenly, and at the same time scrapes the plastic particles on the inner wall of the stirring barrel 2 to prevent waste of materials.

[0032] Specifically, referring toFigure 4 On the outside of the filter box 5, a second motor 17 is fixedly connected. The output shaft of the second motor 17 is fixedly connected with a one-way threaded rod 18 that is rotatably connected to the inside of the filter box 5. The outside of the one-way threaded rod 18 is threadedly connected with a scraper 7.

[0033] In this embodiment, the second motor 17 is started, so that the one-way threaded rod 18 rotates, and then drives the scraper 7 to slide inside the filter box 5, and then scrapes off the plastic dust on the surface of the filter plate 6, and at the same time scrapes out the powder inside the filter box 5.

[0034] Specifically, refer to Figure 1 , Figure 2 and Figure 5 Inside the connecting cylinder 3, a partition plate 22 fixedly connected to the stirring barrel 2 is fixedly connected. The number of filter boxes 5 is two and they are symmetrically distributed. An opening and closing cover 19 is hinged inside the filter box 5, and a sealing gasket is arranged at the connection between the opening and closing cover 19 and the filter box 5.

[0035] In this embodiment, the partition plate 22 divides the inside of the connecting cylinder 3 into two cavities, so that the plastic powder in both cavities can be sucked out by the blower 4 and collected inside the filter box 5. Then, the opening and closing cover 19 is opened to facilitate taking out the dust inside the filter box 5.

[0036] Specifically, refer to Figure 1 and Figure 2 On the top of the processing table 1, a control panel 20 is fixedly connected. On the top of the connecting cylinder 3, a feed hopper 21 is fixedly connected. A ventilation hole is opened inside the barrel cover 13.

[0037] In this embodiment, the control panel 20 controls the stirring of plastic particles, the absorption of plastic powder, and the scraping of dust on the surface of the filter plate 6. The ventilation hole inside the barrel cover 13 prevents a vacuum from forming inside the stirring barrel 2, thus ensuring the normal circulation of air.

[0038] Working principle:

[0039] First: When plastic particles are poured into the stirring barrel 2 for stirring, the plastic dust contained in the plastic particles is raised. The blower 4 is started, so that the dust inside the stirring barrel 2 enters the inside of the connecting cylinder 3 through the stirring barrel 2 and enters the intake pipe 8 through the dust suction member 9, so that the dust enters the inside of the filter box 5 and is filtered by the filter plate 6;

[0040] Then: When dust adheres to the surface of the filter plate 6 and clogs the filter plate 6, the second motor 17 is started, so that the one-way threaded rod 18 rotates, and then drives the scraper 7 to slide inside the filter box 5, and then scrapes off the plastic dust on the surface of the filter plate 6. At the same time, the powder inside the filter box 5 is scraped out of the filter box 5. When the stirring member 12 rotates on the inner wall of the stirring barrel 2, the plastic particles adhering to the inner wall of the stirring barrel 2 are scraped off, and the plastic particles are stirred evenly at the same time. After the stirring is completed, the hydraulic rod 11 is started, so that the stirring member 12 drives the barrel cover 13 to separate from the stirring barrel 2.
