[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural diagram of an embodiment of an internal mixer with environmentally friendly automatic dust extraction, including:

[0035] Please see Figures 1-5 This embodiment of an internal mixer with environmentally friendly automatic dust collection includes a mixer body 1. An exhaust fan 2 is fixedly mounted on the side wall of the mixer body 1. An air supply pipe 3 is fixedly mounted at the output end of the exhaust fan 2. A dust collection box 4 is fixedly mounted at the other end of the air supply pipe 3. A dust collection assembly 5 is rotatably connected inside the dust collection box 4. The dust collection assembly 5 includes a motor 501 located at the bottom of the dust collection box 4. A rotating pipe 502, rotatably connected to the bottom of the other end of the air supply pipe 3, is fixedly mounted at the output end of the motor 501. Multiple nozzles 503 are welded to the outer circumference of the rotating pipe 502. Two bases 504 are snapped into the bottom of the inner cavity of the dust collection box 4. A first filter plate 505 is welded to one end of the top of each base 504. An activated carbon plate 506 is fixedly mounted on the inner circumference of the first filter plate 505. A second filter plate 507 is fixedly installed on the inner wall of the first filter plate 505. A top plate 508 is welded to the top of the dust collection box 4. A cover plate 6 is snapped onto the top of the dust collection box 4. Mounting components 7 are fixedly installed on both sides of the bottom of the cover plate 6. An exhaust pipe 8 is fixedly installed on the bottom of the side wall of the dust collection box 4. The exhaust fan 2 and the motor 501 are electrically connected to an external power source. The exhaust gas generated by the internal mixer body 1 is driven by the exhaust fan 2 to be transported from the gas delivery pipe 3 to the rotating pipe 502. By turning on the motor 501, the rotating pipe 502 is rotated, so that the exhaust gas is sprayed out from multiple nozzles 503. Under the action of centrifugal force, the exhaust gas is made to contact the second filter plate 507 more evenly, improving the filtration and dust collection efficiency. The smoke and dust are adsorbed by the activated carbon plate 506. The filtered exhaust gas is discharged from the exhaust pipe 8.

[0036] It is worth noting that, in order to facilitate the removal of the filter plates for cleaning, the installation component 7 specifically includes a positioning block 701. Positioning grooves 702 are provided on both sides of the top of the dust collection box 4. Each of the two positioning grooves 702 has a slot 703 on its side wall. A rotating rod 704 is rotatably connected to the top of the positioning block 701. A gear 705 is fixed to the bottom of the rotating rod 704. The gear 705 meshes with a toothed plate 706. A spring 707 is fixed to one end of the toothed plate 706. By rotating the rotating rod 704, the gear 705 rotates, causing the toothed plate 706 to move inward and the cover plate 6 to move upward. The first filter plate 505, activated carbon plate 506, and second filter plate 507 can be removed for cleaning or replacement. After reinstallation, the positioning block 701 is inserted into the positioning groove 702, the rotating rod 704 is released, and the toothed plate 706 moves and engages with the slot 703 through the rebound force of the spring 707, thus locking the filter plates.

[0037] Next, to facilitate the cleaning of smoke and dust, specifically, the base 504 has an L-shaped cross-section, and the pore size of the first filter plate 505 is smaller than that of the second filter plate 507. The L-shaped cross-section of the base 504 facilitates the collection of smoke and dust filtered from the surface of the second filter plate 507 into the base 504, making it easy to remove and clean. The first filter plate 505, with a pore size smaller than that of the second filter plate 507, facilitates layered filtration, effectively improving the filtration effect.

[0038] Meanwhile, to facilitate the splicing of the two bases 504, a groove is opened at the bottom of the inner cavity of the dust collection box 4. The size and position of the base 504 match the size and position of the groove. Magnetic sheets 509 are fixed on the side wall of the base 504 and the side wall of the top plate 508. The groove that matches the size and position of the base 504 makes it easy to define the position of the base 504. The magnetic sheets 509 make it easy for the two bases 504 to be adsorbed and spliced, avoiding separation and affecting dust collection and filtration.

[0039] Furthermore, to prevent unfiltered smoke from escaping, a sealing ring 510 is fixedly installed on the inner circumference of the top plate 508. The sealing ring 510 is made of silicone rubber, and its size and position match the size and position of the gas supply pipe 3. The silicone rubber sealing ring 510 helps to improve the sealing performance and prevents unfiltered smoke from escaping from the gap between the gas supply pipe 3 and the top plate 508.

[0040] It is worth noting that, in order to improve stability, the dimensions and positions of the positioning block 701 are matched with the dimensions and positions of the positioning groove 702, and the dimensions and positions of the slot 703 are matched with the dimensions and positions of the other end of the toothed plate 706. The slot 703, which matches the dimensions and positions of the other end of the toothed plate 706, facilitates improved engagement stability and prevents loosening from affecting dust collection.

[0041] Finally, to facilitate use by staff, a handle 708 is fixedly provided on the top of the rotating rod 704. Multiple striped protrusions are fixedly provided on the outer circumference of the handle 708. The striped protrusions of the handle 708 facilitate the increase of friction and make it easier for staff to turn it.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0044] Exhaust fan 2: 4-72-5 / A;

[0045] Motor 501: Y90S-2.

[0046] Combination Figures 1-5 The specific usage process of the internal mixer with environmentally friendly automatic dust collection in this embodiment is as follows:

[0047] 1: When this device is needed to be used for an internal mixer with environmental protection automatic dust collection, two first filter plates 505 are spliced ​​and fitted outside the rotating tube 502. The exhaust fan 2 is started to transport the exhaust gas generated by the internal mixer body 1 from the air supply pipe 3 to the rotating tube 502. The motor 501 is started to make the rotating tube 502 rotate and drive the exhaust gas to be evenly sprayed from multiple nozzles 503 to the second filter plate 507. The filtered exhaust gas is discharged from the exhaust pipe 8.

[0048] 2: Twist the lever 708 to make the lever 704 drive the gear 705 to rotate, thereby moving the toothed plate 706 inward and the cover plate 6 upward. Take out the first filter plate 505, activated carbon plate 506, and second filter plate 507 for cleaning or replacement. After reinstallation, the positioning block 701 is inserted into the positioning groove 702. Release the lever 704, and the rebound force of the spring 707 will drive the toothed plate 706 to move and engage with the groove 703.
