Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model relates to a dust collection device for a mixing mill used in the production of halogen-free polyolefins. It includes a dust collector body 1, a dust collection pipe 2 fixedly installed on one side of the dust collector body 1, a dust collection hood 3 fixedly installed at the end of the dust collection pipe 2 away from the dust collector body 1, a support frame 4 located directly below the dust collector body 1, mounting strips 25 symmetrically fixedly installed at the bottom of the support frame 4, and mounting holes 26 extending through both ends of the mounting strips 25. An adjusting support assembly 5 is installed inside the support frame 4, with its top extending to the top of the support frame 4. The dust collector body 1 is fixedly installed on the top of the adjusting support assembly 5. During use, the interaction of the dust collector body 1, dust collection pipe 2, dust collection hood 3, support frame 4, and adjusting support assembly 5 allows for adjustment according to the actual installation height of the mixing mill, facilitating better operation by the operator and thus achieving better practicality.

[0024] The adjusting support assembly 5 includes symmetrically arranged strip plates 6. Two strip plates 6 are symmetrically fixedly installed inside the top of the support frame 4. Transmission gears 7 are symmetrically arranged between the two strip plates 6. Transmission shafts 8 are fixedly installed inside the two transmission gears 7. The two ends of the two transmission shafts 8 are respectively rotatably installed inside the two strip plates 6.

[0025] A transmission rack 9 is meshed with the outer side of the transmission gear 7. The bottom of the transmission rack 9 is in movable contact with the inner bottom of the support frame 4. A rectangular opening 10 is symmetrically opened through the top of the support frame 4. The tops of the two transmission racks 9 are movable through the rectangular opening 10 and extend to the top of the support frame 4. A movable support plate 11 is fixedly installed on the top of the transmission rack 9. The dust collector body 1 is fixedly installed on the top of the movable support plate 11. A strip frame 12 is fixedly installed on the outer side of one of the strip plates 6.

[0026] One end of each of the two drive shafts 8 extends movably through and into the interior of the strip frame 12. A control switch 13 is fixedly installed in the middle of the side of the strip frame 12 away from the strip plate 6. An adjustment motor 14 is fixedly installed on one side of the strip frame 12, and the adjustment motor 14 is energized and connected to the control switch 13. A drive shaft 15 is rotatably installed inside the strip frame 12. The output shaft of the adjustment motor 14 extends movably through one side of the strip frame 12 and is fixedly connected to one end of the drive shaft 15.

[0027] Inside the strip frame 12 and on the outside of the drive shaft 15, drive bevel gears 16 are symmetrically fixedly installed. Both drive bevel gears 16 are meshed with transmission bevel gears 17 on their outer sides. The two transmission bevel gears 17 are respectively fixedly installed on one end of the transmission shaft 8 inside the strip frame 12.

[0028] The bottom four corners of the movable support plate 11 are fixedly installed with positioning vertical rods 18. The top of the support frame 4 is symmetrically opened with four positioning sliding holes 19, and the four positioning vertical rods 18 are respectively movably installed inside the four positioning sliding holes 19. The bottom of the positioning vertical rods 18 is fixedly installed with a circular limiting block 20, and the bottom of the circular limiting block 20 is in movable contact with the bottom of the inside of the support frame 4.

[0029] A positioning sleeve 21 is fixedly installed on the bottom end of the transmission rack 9 away from the transmission gear 7. A positioning slide rod 22 is slidably installed inside the positioning sleeve 21, and the positioning slide rod 22 is fixedly installed inside the support frame 4. A positioning slider 23 is fixedly installed on the side of the positioning sleeve 21 away from the transmission rack 9. Positioning grooves 24 are opened through both sides of the support frame 4, and the positioning slider 23 is slidably installed inside the positioning grooves 24. During use, the interaction of the positioning sleeve 21, positioning slide rod 22, positioning slider 23 and positioning groove 24 makes it easier for the transmission rack 9 to achieve better stability when moving, thereby ensuring that the adjustment support assembly 5 can work stably.

[0030] During operation, the starting and adjusting motor 14 drives the drive shaft 15 to rotate, which in turn drives the drive bevel gear 16 to rotate. The drive bevel gear 16 then drives the transmission bevel gear 17 to rotate, which in turn drives the transmission shaft 8 to rotate. The transmission shaft 8 then drives the transmission gear 7 to rotate, which in turn drives the transmission rack 9 to move upward. The transmission rack 9 causes the positioning sleeve 21 to slide outside the positioning slide rod 22, and the positioning sleeve 21 causes the positioning slider 23 to slide inside the positioning groove 24, ensuring better stability of the transmission rack 9 during movement. The transmission rack 9 also causes the movable support plate 11 to move upward, and the movable support plate 11 causes the positioning vertical rod 18 to slide inside the positioning sliding hole 19. This ensures better stability of the movable support plate 11 during movement. The movable support plate 11 drives the dust collector body 1 to move upward, and the dust collector body 1 drives the dust collection hood 3 to move upward through the dust collection pipe 2. After the dust collection hood 3 moves to a height that matches the internal mixer, the adjustment motor 14 stops. Then, the entire device is moved laterally so that the dust collection hood 3 is moved directly above the internal mixer. Then, the mounting strip 25 is fixedly installed using mounting bolts that match the diameter of the mounting hole 26, thereby achieving the fixed installation of the entire device. This allows the dust collection device for the internal mixer used in the production of halogen-free polyolefins to be adjusted according to the actual installation height of the internal mixer during use, so that the operator can operate it better and achieve better practicality.
