Abstract
Description
Technical Field
[0001] This utility model relates to the field of color masterbatch mixing silos, specifically a dust cleaning device for color masterbatch mixing silos. Background Technology
[0002] In modern industrial production, color masterbatch, as a colorant widely used in plastic products and other fields, plays a crucial role in its mixing process. The color masterbatch mixing silo, as a key piece of equipment in this process, is responsible for containing and mixing different color masterbatch particles to achieve the desired color and quality standards. However, a large amount of dust is inevitably generated during the processes of color masterbatch entering the mixing silo, stirring and mixing within the silo, and subsequent discharge.
[0003] According to existing technologies, dust spillage during the mixing process not only wastes raw materials but also pollutes the production environment and affects workers' health. Currently, the industry generally uses closed mixing silos or exhaust dust removal systems to reduce dust spillage. However, the complete enclosure of the closed mixing silo affects the convenience of operation, and dust will still escape during the feeding process. Exhaust dust removal systems have high energy consumption and limited efficiency in capturing small dust particles.
[0004] Therefore, those skilled in the art have provided a dust cleaning device for a masterbatch mixing silo to solve the problems mentioned in the background art. Utility Model Content

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific implementation method 1:
[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This embodiment of a dust cleaning device for a masterbatch mixing silo includes a mixing tank 1, a dust collection hood 2 on top of the mixing tank 1, a discharge tank 3 on top of the dust collection hood 2, a through hole on top of the discharge tank 3 and a fixedly connected sealed box 4, multiple rotating rods 6 rotatably connected inside the discharge tank 3, baffles 7 fixedly connected to the outside of the rotating rods 6, a feed pipe 10 fixedly connected to the top of the mixing tank 1, a buffer pipe 11 fixedly connected to the bottom of the discharge tank 3, an annular pipe 12 on the outside of the dust collection hood 2, a second motor 15 fixedly connected to the bottom of the mixing tank 1, the output shaft of the second motor 15 passing through the mixing tank 1 and fixedly connected to a stirring shaft 16, multiple dust outlet holes 20 on the outside of the feed pipe 10 located inside the dust collection hood 2, and a discharge port fixedly connected to the bottom of the mixing tank 1. A first motor 5 is fixedly connected to the outside of the discharge hopper 3. The output shaft of the first motor 5 passes through the discharge hopper 3 and is fixedly connected to one of the rotating rods 6. A part of the rotating rod 6 is located inside the closed box 4 and is rotatably connected to the closed box 4. A baffle 7 is located inside the closed box 4. One end of the rotating rod 6 is located outside the discharge hopper 3 and is fixedly connected to a rotating plate 8. A connecting rod 9 is provided on the side of the discharge hopper 3. The connecting rod 9 is rotatably connected to multiple rotating plates 8. The connection point between the connecting rod 9 and the rotating plate 8 is located on the side of the rotating plate 8 away from the rotating rod 6. A dust collection hood 2 is located outside the feed pipe 10 and is fixedly connected to the feed pipe 10. The bottom end of the buffer pipe 11 is fixedly connected to the top end of the feed pipe 10. An air suction pipe 13 is connected to the outside of the annular pipe 12. Multiple suction heads 14 are connected to the inside of the annular pipe 12. The end of the suction head 14 away from the annular pipe 12 is located inside the dust collection hood 2. Specific implementation method 2:
[0040] Please see Figure 3 , Figure 4 , Figure 5 In this embodiment, a dust cleaning device for a masterbatch mixing silo has two scrapers 21 fixedly connected to the outer side of the stirring shaft 16, a rotating column 17 fixedly connected to the top of the stirring shaft 16, a spiral blade 18 fixedly connected to the outer side of the rotating column 17, the spiral blade 18 being located inside the buffer tube 11, a fixing plate 19 fixedly connected to the inner side of the discharge hopper 3, and the top of the rotating column 17 being rotatably connected to the fixing plate 19.
[0041] This embodiment of a dust cleaning device for a masterbatch mixing hopper, it should be noted, is that, through the arrangement of dust collection hood 2, discharge hopper 3, enclosed box 4, first motor 5, rotating rod 6, baffle 7, feed pipe 10, suction head 14, and dust outlet 20, the device can freely close or open the mixing hopper 1 during use. This not only prevents dust from drifting out of the mixing hopper 1 during mixing but also facilitates the discharge of material from the mixing hopper 1. Furthermore, during discharge, the device can enclose and absorb dust, reducing dust drift and solving the environmental pollution and raw material contamination caused by dust overflow from the mixing hopper during masterbatch production. Waste, especially the difficulty in effectively controlling dust escape during the feeding process, is addressed by setting up a stirring shaft 16, a second motor 15, a rotating column 17, a scraper 21, and a spiral blade 18. This device can clean the inner wall of the mixing tank 1, reducing dust adhesion, and can also slowly convey materials during discharge. This solves the problem of dust adhering to the inner wall of the mixing tank 1, keeping the mixing tank 1 clean, and avoids the situation where a large amount of dust is generated due to impact when materials are directly poured in in the traditional feeding method, thus reducing dust overflow during feeding from the source.
[0042] The working principle of the above embodiment is as follows: The user places external materials into the top of the closed box 4. At this time, the baffle 7 is in a vertical state. Then, the materials fall into the inside of the discharge bucket 3 through the closed box 4. During the descent of the materials, the materials are impacted and begin to scatter. The scattered material dust is blocked by the discharge bucket 3. At this time, the first motor 5 is started. The output shaft of the first motor 5 causes one of the rotating rods 6 to rotate. After the rotating rod 6 rotates, one of the rotating plates 8 rotates. Then, one of the rotating plates 8 drives the connecting rod 9 to rotate. Then, the connecting rod 9 drives the remaining rotating plates 8 to rotate, thereby causing the rotating rod 6 to rotate. Then, multiple rotating rods 6 cause multiple baffles 7 to rotate, thereby sealing the closed box 4 and preventing dust from overflowing. At this time, the second motor 15 is started. The output shaft of the second motor 15 causes the stirring shaft 16 to rotate. After the stirring shaft 16 rotates, the rotating column 17 rotates. After the rotating column 17 rotates, the spiral blade 18 rotates. Then, the spiral blade 18 conveys the color masterbatch inside the discharge bucket 3, so that the color masterbatch falls into the feed pipe 10 through the buffer pipe 11. Inside the mixing tank 1, some of the color masterbatch falls into the dust collection hood 2 through the dust outlet 20, and then slides back down into the feed pipe 10, thus entering the mixing tank 1. The mixing shaft 16 then stirs the color masterbatch inside the mixing tank 1, while the scraper 21 rotates with the mixing shaft 16. The rotating scraper 21 cleans the inner wall of the mixing tank 1, reducing dust adhesion. When it is necessary to add material back into the mixing tank 1, the first motor 5 opens the baffle 7 to close the tank. 4. When the sealed box 4 is opened, some of the color masterbatch dust stirred inside the mixing tank 1 overflows upwards. At this time, the suction pipe 13 is connected to the external suction pump. The suction pump generates suction through the suction pipe 13 to generate suction in the annular pipe 12, which in turn generates suction in the suction head 14. When the dust overflows upwards, the dust passes through the dust outlet 20, and the suction in the suction head 14 sucks up the dust, preventing the dust from overflowing. At this time, the user puts the material into the discharge tank 3 through the sealed box 4, and then the external suction pump can be turned off to discharge the material.
