Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, specifically to a paper pulp filtration device. Background Technology

[0002] Pulp is a fibrous material made from plant fibers through various processing methods. It can be classified into mechanical pulp, chemical pulp, and chemimechanical pulp based on the processing method. Patent CN202223172912.6 discloses a pulp mixing and refining device for corrugated paper production. This device uses a base plate to fix and position the bottom refining cylinder, supported by lower support plates on both sides of the base plate. A center plate is installed in the middle of the refining cylinder, clamped on one side by an arc-shaped clamping plate, positioning the center plate against the bottom of an electric telescopic column. This facilitates the lifting and lowering of the top plate at the top of the refining cylinder, allowing corrugated paper production pulp to be added into the cylinder through discharge holes on both sides of the top plate. However, during the use of pulp filtration equipment, concave filter cylinders are used to filter the pulp. Impurities tend to accumulate on the inner wall of the concave filter cylinder, potentially affecting its operation. Therefore, we propose a pulp filtration device for paper processing. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a paper pulp filtration device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a paper processing pulp filtration device, including a grinding equipment body. The outer wall surface of the grinding equipment body is bolted with hydraulic rods for adjustment, and there are two sets of hydraulic rods. The power output end of the hydraulic rod is fitted with a cover plate that fits with the top opening end of the grinding equipment body. The side of the cover plate near the inner side of the grinding equipment body is bolted with a support cylinder frame. The bottom surface of the cylinder frame is integrally constructed with a ring frame for auxiliary support. The side of the ring frame located inside the cylinder frame and the inner circumferential surface of the cylinder frame are both equipped with a screen layer for pulp filtration. The side of the ring frame located inside the cylinder frame is rotatably installed with a support plate. The outer wall surface of the plate is bolted with an inclined plate that abuts against the screen layer. The end of the inclined plate away from the plate frame is integrally constructed with a scraper for auxiliary scraping.

[0005] The outer end surface of the disc base is integrally constructed with a shaft cylinder, and a stirring shaft for stirring the raw slurry is rotatably installed on the side of the cover plate located inside the cylinder frame. The outer end surface of the stirring shaft is provided with an arc-shaped groove that fits the inner circumference of the shaft cylinder, and there are multiple sets of arc-shaped grooves. The top surface of the cover plate is equipped with a reducer that is connected to the stirring shaft through bolts, and a servo motor is installed at the power input end of the reducer.

[0006] By adopting the above technical solution, during the use of the paper pulp filtration equipment, the disc seat on the ring frame can be rotated. The rotation of the disc seat can easily drive the inclined plate to rotate, and the inclined plate can easily drive the scraper to swing and move along the inner circumference of the cylinder frame. The inclined plate and the scraper cooperate with each other to facilitate scraping and cleaning of the screen layer on the cylinder frame and the ring frame. This allows the pulp or pulp impurities accumulated on the screen layer to move, thus enabling smoother filtration and grinding.

[0007] When pulp is added into the grinding equipment through the opening on the cover plate, the servo motor on the cover plate surface operates and, under the action of the reducer, drives the stirring shaft at the bottom of the cover plate to rotate. This allows the stirring shaft to stir and grind the pulp inside the cylinder. Simultaneously, because the other end of the stirring shaft can easily be inserted into the shaft cylinder on the disc base, and the arc groove on the stirring shaft matches the protrusion on the inner circumference of the shaft cylinder, the rotation of the stirring shaft can drive the shaft cylinder to rotate, causing the disc base to rotate as well. Subsequently, the disc base can easily drive the inclined plate and scraper to rotate and scrape the screen layer, providing convenient power. Moreover, the shaft cylinder and stirring shaft can be separated simply by disassembling the cylinder base, facilitating maintenance and making the pulp filtration equipment for paper processing more convenient to use.

[0008] Specifically, both the outer wall surface of the scraper and the outer wall surface of the inclined plate are fitted with rubber strips.

[0009] By adopting the above technical solution, the rubber strip has good elasticity, which facilitates the improvement of the effect of the inclined plate and scraper on the screen layer during scraping and cleaning.

[0010] Specifically, the top surface of the tube frame has an integrally formed protrusion that is inserted and connected to the cover plate, and there are multiple sets of protrusions. The side of the tube frame near the cover plate has an integrally formed ring that fits with the cover plate.

[0011] By adopting the above technical solution, the multiple sets of protruding rods on the tube frame and the holes on the base plate can be interlocked, which can improve the stability of the tube frame installed on the base plate. The ring on the tube frame can be interlocked with the groove on the base plate, which can improve the tightness of the connection between the tube frame and the base plate and reduce the situation of pulp seeping into the gap between the two.

[0012] Specifically, a protective rubber ring is glued to one end of the stirring shaft near the shaft cylinder.

[0013] By adopting the above technical solution, the rubber ring has good elasticity, which helps to reduce the impact damage that occurs when the stirring shaft and the shaft cylinder are jammed together.

[0014] Specifically, the outer wall surface of the grinding equipment body is equipped with a controller that is electrically connected to the servo motor.

[0015] By adopting the above technical solution, the controller can easily control the operation of the servo motor, making the servo motor more convenient to use. It also facilitates the control of the operation of the paper processing pulp filtration equipment, making it easier to filter and grind the pulp.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of hydraulic rods, cover plates, cylinder frames, ring frames, screen layers, disc seats, inclined plates, and scrapers, enables the disc seats on the ring frames to rotate during the use of paper pulp filtration equipment. The rotation of the disc seats facilitates the rotation of the inclined plates, and the inclined plates facilitate the oscillating displacement of the scrapers along the inner circumference of the cylinder frames. This allows the inclined plates and scrapers to cooperate to easily scrape and clean the screen layers on the cylinder frames and ring frames, thereby allowing the pulp or pulp impurities accumulated on the screen layers to move and thus enabling smoother filtration and grinding.

[0018] 2. The technical solution of this application, through the design of the shaft cylinder, stirring shaft, arc groove, reducer, and servo motor, enables the servo motor on the surface of the cover plate to operate when the pulp is added into the grinding equipment through the opening on the surface of the cover plate. Under the operation of the reducer, the stirring shaft at the bottom of the cover plate is rotated, allowing the stirring shaft to stir and grind the pulp inside the cylinder. At the same time, since the other end of the stirring shaft can be easily inserted into the shaft cylinder on the disc base, and the arc groove on the stirring shaft matches the protrusion on the inner circumference of the shaft cylinder, the rotation of the stirring shaft can drive the shaft cylinder to rotate, causing the disc base to rotate accordingly. Subsequently, the disc base can easily drive the inclined plate and scraper to rotate and scrape the screen layer, providing convenient power. Moreover, the shaft cylinder and stirring shaft can be separated simply by disassembling the cylinder base, facilitating maintenance and making the pulp filtration equipment for paper processing more convenient to use.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a paper pulp filtration device, including a grinding equipment body 1. Two sets of hydraulic rods 2 are bolted to the outer wall surface of the grinding equipment body 1 for adjustment. A cover plate 3, matching the top opening of the grinding equipment body 1, is bolted to the power output end of each hydraulic rod 2. A support cylinder frame 4 is bolted to the side of the cover plate 3 closest to the inner side of the grinding equipment body 1. A ring frame 5 for auxiliary support is integrally formed on the bottom surface of the cylinder frame 4. A screen layer 6 for pulp filtration is mounted on both the inner side of the ring frame 5 and the inner circumferential surface of the cylinder frame 4. A support plate 7 is rotatably mounted on one side of the cover plate 3, and an inclined plate 8 that abuts against the screen layer 6 is bolted to the outer wall surface of the cover plate 3. A scraper 9 for assisting scraping is integrally constructed at the end of the inclined plate 8 away from the cover plate 7. A shaft cylinder 10 is integrally constructed on the outer end surface of the cover plate 3, and a stirring shaft 11 for stirring the raw slurry is rotatably mounted on the side of the cover plate 3 located inside the cylinder frame 4. An arc-shaped groove 12 that fits the inner circumference of the shaft cylinder 10 is opened on the outer end surface of the stirring shaft 11, and there are multiple sets of arc-shaped grooves 12. A reducer 13 that is connected to the stirring shaft 11 is bolted to the top surface of the cover plate 3, and a servo motor 14 is installed at the power input end of the reducer 13.

[0026] During use, the disc seat 7 on the ring frame 5 can rotate, which facilitates the rotation of the inclined plate 8 and the swing displacement of the scraper 9 along the inner circumference of the cylinder frame 4. The inclined plate 8 and the scraper 9 cooperate with each other to scrape and clean the screen layer 6 on the cylinder frame 4 and the ring frame 5, so that the pulp or pulp impurities accumulated on the screen layer 6 can move and be filtered and ground more smoothly.

[0027] When pulp is added into the grinding equipment through the opening on the surface of the cover plate 3, the servo motor 14 on the surface of the cover plate 3 operates and drives the stirring shaft 11 at the bottom of the cover plate 3 to rotate under the operation of the reducer 13. This allows the stirring shaft 11 to stir and grind the pulp inside the cylinder 4. At the same time, since the other end of the stirring shaft 11 can be easily inserted into the shaft cylinder 10 on the disc base 7, and the arc groove 12 on the stirring shaft 11 fits into the protrusion on the inner circumference of the shaft cylinder 10, the rotation of the stirring shaft 11 can drive the shaft cylinder 10 to rotate, and the disc base 7 will rotate accordingly. Then the disc base 7 can easily drive the inclined plate 8 and the scraper 9 to rotate and scrape the screen layer 6, providing power for it. Moreover, the shaft cylinder 10 and the stirring shaft 11 can be separated simply by removing the cylinder base 4, which is convenient for maintenance and makes the pulp filtration equipment for paper processing more convenient to use.

[0028] like Figure 2 As shown, both the outer wall surface of the scraper 9 and the outer wall surface of the inclined plate 8 are fitted with rubber strips 17.

[0029] When in use, the rubber strip 17 has good elasticity, which facilitates the improvement of the scraping and cleaning effect of the inclined plate 8 and scraper 9 on the screen layer 6.

[0030] like Figure 3 As shown, the top surface of the tube frame 4 has an integrally constructed protruding rod 15 that is inserted and connected to the cover plate 3, and there are multiple sets of protruding rods 15. The side of the tube frame 4 near the cover plate 3 has an integrally constructed ring body 16 that fits into the cover plate 3.

[0031] During use, the multiple sets of protruding rods 15 on the tube frame 4 interlock with the holes on the base plate, which helps to improve the stability of the tube frame 4 when installed on the base plate. The ring body 16 on the tube frame 4 can easily fit into the groove on the base plate, which helps to improve the tightness of the connection between the tube frame 4 and the base plate, and helps to reduce the situation of pulp seeping into the gap between the two.

[0032] like Figure 2 As shown, a protective rubber ring 18 is glued to one end of the stirring shaft 11 near the shaft cylinder 10.

[0033] When in use, the rubber ring 18 has good elasticity, which helps to reduce the impact damage that occurs when the stirring shaft 11 and the shaft cylinder 10 are jammed together.

[0034] like Figure 1 As shown, a controller 19 electrically connected to the servo motor 14 is mounted on the outer wall surface of the grinding equipment body 1.

[0035] When in use, the controller 19 can easily control the operation of the servo motor 14, making the servo motor 14 more convenient to use. It can also facilitate the control of the operation of the paper processing pulp filtration equipment, making it convenient to filter and grind the pulp.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. When the pulp is added into the grinding equipment through the opening on the surface of the cover plate 3, the controller 19 on the outside of the grinding equipment body 1 can be used to operate the servo motor 14 on the surface of the cover plate 3. Under the operation of the reducer 13, the stirring shaft 11 at the bottom of the cover plate 3 is rotated, allowing the stirring shaft 11 to stir and grind the pulp inside the cylinder 4. Simultaneously, because the other end of the stirring shaft 11 can easily interlock with the shaft cylinder 10 on the disc base 7, and the arc groove 12 on the stirring shaft 11 matches the protrusion on the inner circumference of the shaft cylinder 10, the stirring... When the mixing shaft 11 rotates, it drives the shaft cylinder 10 to rotate, causing the disc base 7 to rotate as well. The rotation of the disc base 7 then drives the inclined plate 8 to rotate, and the inclined plate 8 drives the scraper 9 to swing and move along the inner circumference of the cylinder frame 4. The inclined plate 8 and the scraper 9 work together to scrape and clean the screen layer 6 on the cylinder frame 4 and the ring frame 5, so that the pulp or pulp debris accumulated on the screen layer 6 can move, thus allowing for smoother filtration and grinding. Moreover, the shaft cylinder 10 and the mixing shaft 11 can be separated simply by disassembling the cylinder frame 4, which facilitates maintenance and makes the paper processing pulp filtration equipment more convenient to use.
