Description

Technical Field

[0001] This utility model belongs to the field of papermaking equipment technology, and in particular relates to a mixed pulp filtration device. Background Technology

[0002] Papermaking is a complex and delicate process, mainly including raw material preparation, pulping, screening, bleaching, papermaking, and post-processing. Raw materials such as wood, waste paper, grass, and bamboo are crushed and pulped. The pulp is then filtered through filtration equipment to remove large particles of impurities. After bleaching, papermaking, dewatering, and drying, large particles of impurities in the pulp (such as fiber fragments and colloids) tend to adhere to the surface of the filter screen during filtration. These particles gradually accumulate and clog the filter pores, leading to a decrease in filtration efficiency. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a mixed pulp filtration device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mixed pulp filtration device includes a machine body, in which a filter barrel is rotatably mounted, and the bottoms of both the machine body and the filter barrel are hemispherical cylindrical structures.

[0006] The machine body is equipped with a rotating ring, and the outer wall of the rotating ring is in contact with the inner wall of the machine body. The bottom of the rotating ring is equipped with scrapers arranged in a circular array with the center of the rotating ring as the center. One side of the scraper is in contact with the inner side of the filter barrel.

[0007] The rotating ring rotates in the opposite direction to the filter barrel.

[0008] The top of the machine body is provided with a feeding hopper, and the bottom of the machine body is provided with a discharging pipe;

[0009] The bottom of the filter barrel is connected to a waste pipe, and the other end of the waste pipe extends out of the machine body;

[0010] Both the waste pipe and the discharge pipe are equipped with valves.

[0011] With the above technical solution, after the mixed pulp enters the machine body from the feed hopper, the filter barrel and the rotating ring rotate synchronously in opposite directions, which can shake the pulp and improve the filtration efficiency of the filter barrel. At the same time, the rotating ring drives the scraper to rotate along the inner wall of the filter barrel, which promptly scrapes off larger impurities to prevent them from clogging the filter holes of the filter barrel and ensures that the filtration effect is not affected. After filtration, the pulp is discharged from the discharge pipe at the bottom of the machine body, while large impurities fall to the hemispherical bottom of the filter barrel after being scraped off by the scraper and are finally discharged through the waste pipe, thus achieving effective separation of pulp and impurities.

[0012] Furthermore, the rotating ring is provided with connecting blocks, and two connecting blocks are arranged in a cross shape inside the rotating ring, with both ends of the connecting blocks fixedly connected to the inner sidewall of the rotating ring.

[0013] The top of the connecting block is provided with a first rotating shaft, which is coaxial with the rotating ring. One end of the first rotating shaft extends out of the top of the machine body and is connected to a motor, which is fixedly installed on the top of the machine body.

[0014] Through the above technical solution, the motor drives the first rotating shaft to rotate, which in turn drives the rotating ring to rotate, thereby driving the scraper to scrape off impurities from the inner wall of the filter barrel.

[0015] Furthermore, a first gear is fitted on the outer side of the machine body, the first gear is rotatably connected to the machine body, and the inner sidewall of the first gear is connected to the outer sidewall of the filter barrel.

[0016] The side of the machine body is provided with a connecting frame, which is a U-shaped structure. A drive wheel is rotatably mounted on the connecting frame via a second rotating shaft, and the drive wheel is meshed with a first gear.

[0017] The machine body is equipped with a linkage component, which connects the drive wheel and the motor and drives the drive wheel to rotate.

[0018] The above technical solution uses a drive wheel to rotate the first gear, which in turn rotates the filter barrel.

[0019] Furthermore, the linkage assembly includes two worm gears and a worm;

[0020] One of the worm gears is coaxially connected to the first rotating shaft, and the other worm gear is coaxially connected to the second rotating shaft;

[0021] A fixing block is provided on the top of the machine body;

[0022] One end of the worm gear is rotatably mounted on the connecting frame, and the other end is rotatably mounted on the fixed block;

[0023] The two ends of the worm are respectively engaged with two worm wheels.

[0024] With the above technical solution, when the motor drives the worm gear on the first rotating part to rotate, it drives another worm gear to rotate through the worm, thereby driving the drive wheel to rotate, which in turn drives the first gear to rotate the filter barrel, thus achieving synchronous rotation of the scraper and the filter barrel.

[0025] Furthermore, stirring rods are linearly arranged on the side of the scraper away from the inner wall of the filter barrel.

[0026] Furthermore, the stirring rod is inclined.

[0027] The above technical solution allows for better agitation of the pulp during filtration, thereby improving filtration efficiency.

[0028] Furthermore, the outer side of the machine body is provided with support legs, and the four support legs are evenly distributed around the machine body to provide stable support for the machine body.

[0029] This utility model has the following beneficial effects:

[0030] This invention utilizes the synchronous counter-rotation of the filter barrel and the rotating ring to agitate the pulp, thereby improving the filtration efficiency of the filter barrel. Simultaneously, the rotating ring drives the scraper to rotate along the inner wall of the filter barrel, promptly scraping away larger impurities to prevent them from clogging the filter holes and ensuring that the filtration effect is not affected. After filtration, the pulp is discharged from the discharge pipe at the bottom of the machine, while larger impurities fall to the hemispherical bottom of the filter barrel after being scraped off by the scraper and are finally discharged through the waste pipe, achieving effective separation of pulp and impurities.

[0046] After the mixed pulp enters the machine body 1 from the feed hopper 11, the filter barrel 2 and the rotating ring 3 rotate synchronously in opposite directions, which can shake the pulp and improve the filtration efficiency of the filter barrel 2. At the same time, the rotating ring 3 drives the scraper 4 to rotate along the inner wall of the filter barrel 2, which promptly scrapes off larger impurities to prevent them from clogging the filter holes of the filter barrel 2 and ensures that the filtration effect is not affected. After filtration, the pulp is discharged from the discharge pipe 12 at the bottom of the machine body 1, while the large impurities fall to the hemispherical bottom of the filter barrel 2 after being scraped off by the scraper 4, and are finally discharged through the waste pipe 5, thus achieving effective separation of pulp and impurities.

[0047] Furthermore, the rotating ring 3 is provided with connecting blocks 31, and two connecting blocks 31 are arranged in a cross shape inside the rotating ring 3, and the two ends of the connecting blocks 31 are fixedly connected to the inner sidewall of the rotating ring 3; the top of the connecting blocks 31 is provided with a first rotating shaft 32, the first rotating shaft 32 is coaxially arranged with the rotating ring 3, and one end of the first rotating shaft 32 extends out of the top of the machine body 1 and is connected to a motor 33, and the motor 33 is fixedly arranged on the top of the machine body 1. A first gear 21 is fitted on the outer side of the body 1, and the first gear 21 is rotatably connected to the body 1. The inner side wall of the first gear 21 is connected to the outer side wall of the filter barrel 2. A connecting frame 13 is provided on the side of the body 1. The connecting frame 13 has a U-shaped structure. A drive wheel 23 is rotatably mounted on the connecting frame 13 via a second rotating shaft 22. The drive wheel 23 is meshed with the first gear 21. A linkage assembly is provided on the body 1. The linkage assembly connects the drive wheel 23 and the motor 33 and drives the drive wheel 23 to rotate. The linkage assembly includes two worm gears 61 and a worm 62.

The scraper 4 scrapes the inner wall of the filter barrel 2 to prevent large particles of impurities from adhering to the filter barrel 2 and causing filter hole blockage. The stirring rod 41 on the other side of the scraper 4 stirs the pulp in the filter barrel 2. At the same time, the worm wheel 61 connected to the first rotating shaft 32 rotates, which drives the worm 62 to rotate. Through the meshing of the worm 62 at the other end with another worm wheel 61, the second rotating shaft 22 is driven to rotate, thereby driving the drive wheel 23 to rotate, which drives the first gear 21 to rotate, and drives the filter barrel 2 to rotate. The filter barrel 2 and the scraper 4 rotate synchronously in opposite directions. After filtration, the pulp is discharged from the discharge pipe 12 at the bottom of the machine body 1, while large impurities fall to the hemispherical bottom of the filter barrel 2 after being scraped off by the scraper 4, and are finally discharged through the waste pipe 5, thus achieving effective separation of pulp and impurities.
