Description

Technical Field

[0001] This utility model relates to the field of papermaking fillers, specifically a rotary screen for preparing papermaking fillers that facilitates material transport. Background Technology

[0002] Paper fillers are solid particles that are largely insoluble in water and added to paper pulp. The purpose of adding them is to improve the paper's opacity, brightness, smoothness, printability (such as increased absorbency and ink absorption), softness, uniformity, and dimensional stability. They can also improve the paper's feel, reduce its hygroscopicity, and decrease fiber usage. Pulp with fillers is easier to dewater and dry, reducing energy consumption and lowering papermaking costs. The disadvantages are a decrease in sizing, stiffness, and strength, especially in paper produced through high-pressure processes, where the decrease is more pronounced. Additionally, paper with fillers is more prone to dusting and linting. These drawbacks can be mitigated by using reinforcing agents and surface sizing.

[0003] Rotary drum screens are widely used in sorting technology, controlling waste sorting by particle size and offering high sorting accuracy. The drum screen's cylinder is typically divided into several sections, depending on the specific situation, with screen holes arranged from small to large. Each section has the same screen hole diameter. Before being used as filling material in papermaking, the material needs to be sieved to ensure the particle size meets requirements. However, existing rotary drum screen mechanisms are inconvenient for conveying the sieved material, and cleaning impurities inside the drum is also troublesome. Therefore, this invention proposes a rotary drum screen for preparing papermaking filling material that facilitates material conveying. Utility Model Content

[0020] Please see Figures 1-3 This utility model provides a technical solution: a rotary screen for preparing papermaking fillers that facilitates material conveying, comprising...

[0021] The screen barrel 1 has transmission gears 2 at both ends, and fixed guide rail grooves 3 at the outer ends of the transmission gears 2. The screen barrel 1 has stirring plates 4 inside.

[0022] The hinge support block 5 is connected to the base plate 6 via a hinge. The base plate 6 has four symmetrical corner positions on the upper end of the base plate 6. Fixed guide wheels 8 are provided between the fixed brackets 7. The base plate 6 has motor support blocks 9 arranged symmetrically in the center of the upper end. The motor support block 9 has a servo motor 10 on the upper end. The servo motor 10 is connected to the transmission shaft 11. The transmission shaft 11 has a gear 12 at the end. The motor support block 9 has a fixed tripod 13 at the lower end. The screen barrel 1 has a discharge barrel 14 on the right end.

[0023] A receiving hopper 15 is provided below the screen hopper 1. A blower 16 is provided at the upper end of the receiving hopper 15. A discharge port is provided on the outer side of the receiving hopper 15.

[0024] Hydraulic rod 17 is provided at the lower end of the base plate 6, and support baffles 18 are provided on both sides of the lower end of the base plate 1 in a symmetrical arrangement.

[0025] The two ends of the screen barrel 1 are equipped with transmission gears 2 by machining and welding. The outer end of the transmission gear 2 is provided with guide rail grooves 3 by machining. The screen barrel 1 is equipped with stirring plates 4 by welding. By setting the stirring plates 4, the material passing through the screen is more uniform and sufficient. During the rotation of the screen barrel 1, the stirring plates 4 have an arc structure. The bottom stirring plates 4 store the material in the groove when rotating. When rotating to a high position, the material falls due to gravity, achieving the stirring effect.

[0026] The hinge support block 5 is connected to the base plate 6 via a large hinge. The four corners of the upper end of the base plate 6 are fixed with bolts to the fixing bracket 7. The fixing bracket 7 is connected to the fixed guide wheel 8 via a rotating shaft. The upper center of the base plate 6 is welded with a symmetrically arranged motor support block 9. The upper end of the motor support block 9 is fixed with a servo motor 10 via bolts. The servo motor 10 is connected to the transmission shaft 11. The end of the transmission shaft 11 is welded with a gear 12. The lower end of the motor support block 9 is welded with a fixed tripod 13. The fixed tripod 13 is fixed to the motor support block 9 via bolts. The right end of the screen barrel 1 is provided with a discharge barrel 14. The discharge barrel 14 is welded to the base plate 6. By setting two servo motors 10, as well as the transmission shaft 11 and gear 12, the controllability and stability of the rotation of the screen barrel 1 are improved. The two servo motors 10 provide sufficient power. The rotating shafts on both sides of the screen barrel 1 drive the screen barrel 1 to rotate via gear transmission, thereby improving stability.

[0027] Below the screen barrel 1 is a receiving barrel 15, which is fixed to the support baffle 18 by bolts. The upper end of the receiving barrel 15 is enclosed by an outer shell and a blower 16 is fixed inside by bolts. The air inlet of the blower 16 is directed to one side of the screen barrel 1, and the receiving barrel 15 is provided with an outlet on the outer side. The air outlet of the blower 16 is directed to the outlet side. By setting up the blower 16 and the outlet on the receiving barrel 15, the screened material can be directly conveyed to the paper filling area, which improves the processing speed. The air inlet of the blower is directed to the feeding point on one side of the receiving barrel 15 and the air outlet is connected to the outlet of the receiving barrel 15, so that the feeding point and the outlet in the receiving barrel are negative pressure, thereby driving the material to be conveyed.

[0028] A hydraulic rod 17 is provided at the lower end of the base plate 6. The upper end of the hydraulic rod 17 is connected to the inside of the base plate 6 by a hinge. When the base plate 6 is raised or lowered, the inside can rotate synchronously. There are symmetrically arranged support baffles 18 on both sides of the lower end of the base plate 1. The hydraulic column at the lower end of the hydraulic rod 17 is connected and fixed to the support baffles 18 by welding. The lower end is in contact with the ground. By setting the hydraulic rod 17 and the hinge support block 5, the screen barrel 1 can be tilted, which improves the convenience of cleaning impurities in the screen barrel 1. The upper end of the hydraulic rod 17 is connected to the inside of the base plate 6 by a hinge. The other side of the base plate 6 is connected to the hinge support block 5 by a large hinge. When the hydraulic rod 17 is raised, the connection between the upper end of the hydraulic rod 17 and the base plate 6 rotates synchronously. The connection between the base plate 6 and the hinge support block 5 can rotate synchronously. The screen barrel 1 is fixed by the fixed guide wheel 8 and the fixed guide rail groove, so as to tilt the screen barrel 1.

[0029] In practical use: By setting the stirring plate 4, more uniform and thorough material screening is achieved. During the rotation of the screen barrel 1, the stirring plate 4 has an arc-shaped structure. The bottom stirring plate 4 stores the material in the groove when rotating. When it rotates to a higher position, the material falls due to gravity, achieving a stirring effect. By setting two servo motors 10, as well as a transmission shaft 11 and gears 12, the controllability and stability of the screen barrel 1's rotation are improved. The two servo motors 10 provide sufficient power. Rotating shafts on both sides of the screen barrel 1 drive the screen barrel 1 to rotate through gear transmission, improving stability. By setting a blower 16 and a discharge port on the receiving barrel 15, the screened material can be directly conveyed to the papermaking filler, improving the processing speed. The blower's air inlet leads to the feeding port on one side of the receiving hopper 15 and the air outlet connects to the discharge port of the receiving hopper 15, creating a negative pressure between the feeding port and the discharge port to drive material conveying. By setting up a hydraulic rod 17 and a hinge support block 5, the screen hopper 1 is tilted, improving the convenience of cleaning impurities inside the screen hopper 1. The upper end of the hydraulic rod 17 is connected to the inside of the base plate 6 via a hinge, and the other side of the base plate 6 is connected to the hinge support block 5 via a large hinge. When the hydraulic rod 17 is raised, the connection between the upper end of the hydraulic rod 17 and the base plate 6 rotates synchronously, and the connection between the base plate 6 and the hinge support block 5 can also rotate synchronously. The screen hopper 1 is fixed by the fixed guide wheel 8 and the fixed guide rail groove, thus achieving the tilting of the screen hopper 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
