[0049] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0050] like Figures 1-3 As shown, this utility model embodiment provides a papermaking gyratory screen, including a screen body 10, a steel cable 20, a motor 30, and two support frames 40;

[0051] The screen body 10 has an open side, which is the discharge port 101. The screen body 10 is equipped with a screen plate 50, which is installed parallel to the top of the screen body 10 and extends to the discharge port 101.

[0052] Two support frames 40 are symmetrically arranged on both sides of the screen body 10, and the two support frames 40 are connected by a crossbar to ensure the stability of the support frames 40.

[0053] The screen body 10 is inclined and fixed to the two support frames 40 by steel cable 20 towards the discharge port 101. One end of the steel cable 20 is fixed to the upper end of the support frame 40, and the other end is fixed to the side wall of the screen body 10.

[0054] The sieve body 10 also has a compartment 102 horizontally fixed on the inner walls of both sides of the sieve body 10, and a vibration drive assembly 60 is provided in the compartment 102.

[0055] The motor 30 is located on one side of the screen body 10, and its output shaft extends through the side wall of the screen body 10 into the compartment 102 and is connected to the vibration drive assembly 60, so that the material can perform three-dimensional circular motion on the screen plate 50 to achieve material screening.

[0056] Specifically, the lower ends of the outer walls on both sides of the screen body 10 are symmetrically provided with fixing frames 103, and the lower ends of the steel cable 20 are fixed in the fixing frames 103.

[0057] To ensure stability, the support frame 40 is equipped with a fixed base 80 at its bottom.

[0058] The screen body 10 has one open side as the discharge port 101, and the screen plate 50 is installed parallel to the top of the screen body 10 to ensure smooth material flow. The screen body 10 is suspended on two support frames 40 by steel cables 20 at an incline toward the discharge port 101, and the material is guided by gravity to quickly complete the screening process. This paper-making gyratory screen has a simple structure and is easy to operate. In addition, the steel cables 20 are highly durable and have a long service life, which reduces the failure rate of the support structure, saves maintenance costs, and ensures production efficiency.

[0059] It should be noted that, in order to ensure sufficient stability, the diameter of the steel cable 20 should not be less than 28mm; in actual use, the diameter of the steel cable 20 should be determined according to the weight of the gyratory screen.

[0060] According to the screening requirements of the material, the screen plate 50 includes a first screen plate 501 and a second screen plate 502. The first screen plate 501 is arranged parallel above the second screen plate 502, and the screen holes of the first screen plate 501 are larger than the screen holes of the second screen plate 502. Thus, coarse slag and long sections can be screened out through the first screen plate 501, and qualified material pieces can be screened out through the second screen plate 502. Fine debris remains at the bottom of the screen body 10.

[0061] Specifically, both the first screen plate 501 and the second screen plate 502 extend outward from the discharge port 101 and divide the discharge port 101 into a first outlet 1011, a second outlet 1012 and a third outlet 1013, so that different materials after screening fall out separately and can be collected separately. The extension of the screen plate 50 outward from the discharge port 101 facilitates the collection of materials.

[0062] Since the screen body 10 is installed at an inclination toward the discharge port 101, in order to fully screen the material, a feed port 70 is provided on the side of the screen body 10 opposite to the discharge port 101. The feed port 70 is connected to the internal space of the screen body 10 located above the first screen plate 501, so that the material can gradually fall from the high point of the screen body 10 to the low point.

[0063] Furthermore, the vibration drive assembly 60 includes:

[0064] The first transmission wheel 601 is fixed to the bottom of the compartment 102 by a bearing seat 602. The bearing seat 602 is provided with a rotating shaft that passes through the first transmission wheel 601. A pendulum 603 is respectively sleeved on both sides of the first transmission wheel 601, and the two pendulums 603 are in the same direction.

[0065] The second drive wheel 604 is located at the bottom of the compartment 102 and is connected to the first drive wheel 601 via a belt 605. The second drive wheel 604 is connected to the first gear 606 in the vertical direction via a drive shaft.

[0066] The second gear 607 is connected to the end of the output shaft of the motor 30 and meshes with the first gear 606 in a two-shaft intersecting manner.

[0067] When in use, the motor 30 is started. The output shaft of the motor 30 drives the second gear 607 to rotate, which in turn drives the first gear 606 to rotate horizontally. The first gear 606 drives the first transmission wheel 601 to rotate through the transmission shaft. The first transmission wheel 601 then drives the first transmission wheel 601 to rotate through the belt 605, which in turn drives the two pendulums 603 on the rotating shaft to rotate at high speed, thereby causing the screen body 10 to shake.

[0068] To avoid the partition 102 affecting the screening of materials, the top of the partition 102 is a cone to facilitate the downward fall of materials.

[0069] like Figure 4 As shown, this utility model also provides a papermaking system, including a conveyor belt 90, and further including a plurality of transversely arranged gyratory screens for papermaking as described in any of the above; the conveyor belt 90 is located below the discharge port 101 and is horizontally conveyed parallel to the plurality of gyratory screens for papermaking.

[0070] Specifically, the conveyor belt 90 includes a first conveyor belt 901, a second conveyor belt 902 and a third conveyor belt 903. The first conveyor belt 901 is located below the first exit 1011, the second conveyor belt 902 is located below the second exit 1012 and the third conveyor belt 903 is located below the third exit 1013.

[0071] Since the discharge port 101 is divided into three outlets by the first screen plate 501 and the second screen plate 502, the papermaking system can accurately and efficiently transport the screened materials by setting a conveyor belt 90 below each outlet of several horizontally arranged papermaking gyratory screens. The system operates smoothly and has high screening efficiency, making it especially suitable for applications with large material volumes.

[0072] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
