Description

Technical Field

[0001] This utility model relates to the field of linear screen technology, and in particular to an upward vibrating linear screen. Background Technology

[0002] In mining, grain processing, and chemical production, material grading and screening are crucial for ensuring subsequent production efficiency and product quality. The upward-vibrating linear screen, with its efficient linear vibration screening principle, can quickly and accurately separate materials of different particle sizes, significantly improving the automation level and throughput of screening operations. Its stable vibration frequency and adjustable screening accuracy can adapt to various material characteristics, reducing the cost and error of manual sorting. Simultaneously, through its layered screening design, it can simultaneously complete material grading and purification, significantly shortening the production process. This is of great significance for promoting large-scale and refined production in various industries.

[0003] Most existing linear vibrating screens use a bottom-vibrating motor drive or an eccentric wheel drive structure. The bottom-vibrating motor is fixed to the bottom of the screen body with bolts, and the centrifugal force generated by the rotation of the motor drives the screen body to vibrate; the eccentric wheel drive drives the eccentric shaft to rotate through the motor, so that the screen body makes reciprocating linear motion.

[0004] However, existing ordinary linear screens are difficult to disassemble and assemble quickly, resulting in excessively long cleaning and replacement times for the screens, which affects the continuity of screening operations. Traditional fixing methods require the use of tools to disassemble bolts or pressure bars one by one. For screens clogged by sticky materials, the process of cleaning and reinstalling is even more cumbersome. Frequent downtime for maintenance not only reduces production efficiency but also increases labor costs. Therefore, an upward vibrating linear screen is proposed to solve the above problems.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an upward vibrating linear screen, including a support frame 1 and a screening frame 2. A vibration motor 3 is installed at the bottom of the screening frame 2. The vibration motor is a YZU series vibration motor with a double eccentric block structure. The excitation force can be precisely controlled by adjusting the angle of the eccentric blocks, providing strong power for the vibration screening of the screen 7. A vibration spring 4 is installed between the support frame 1 and the screening frame 2. A feed hopper 5 is fixedly connected to the top of the screening frame 2. A connecting frame 6 is slidably connected inside the feed hopper 5. A screen 7 is fixedly connected inside the connecting frame 6. Different mesh sizes of screens can be selected according to different material characteristics to meet diverse screening needs. A support frame 8 is fixedly connected inside the support frame 1. The connecting frame 6 fits against the support frame 8. A fixed column 9 is fixedly connected inside the connecting frame 6. A sliding column 10 is slidably connected inside the fixed column 9. An installation component is installed at the bottom of the sliding column 10.

[0033] The mounting components include a mounting pin 11, the top of which is fixedly connected to the bottom of the sliding column 10, enabling quick positioning and fixing of the connecting frame 6. A handle 16 is rotatably connected to the top of the sliding column 10. A support column 13 is fixedly connected inside the mounting pin 11. A 14 is provided on the outer wall of the support column 13, and a retaining bead 15 is fixedly connected to one end of the 14. The retaining bead 15 is slidably connected inside the mounting pin 11. A reset component is provided on the outer wall of the sliding column 10, including a spring 12. The spring 12 is sleeved on the outer wall of the sliding column 10, and its two ends are fixedly connected to the fixed column 9 and the mounting pin 11, respectively. The spring 14 has strong elasticity, pushing the retaining bead 15 to tightly engage in the slot of the support frame 8, enhancing the connection's firmness and preventing the connecting frame 6 from loosening during vibration.

[0034] Reference Figure 1 , Figure 2 and Figure 5 A connecting frame 17 is fixedly connected to the side wall of the screening frame 2. A fixing plate 18 is fixedly connected to the bottom of the connecting frame 17. A push-pull rod 20 is slidably connected inside the fixing plate 18. A sliding plate 21 is fixedly connected to one side of the push-pull rod 20. A sliding column 19 is slidably connected inside the fixing plate 18. A cleaning brush 22 is provided at the bottom of the sliding plate 21. The cleaning brush 22 is in contact with the screen 7. The push-pull rod 20 can move flexibly, driving the sliding plate 21 fixedly connected to one side and the cleaning brush 22 at the bottom to move. The cleaning brush 22 uses bristles of moderate softness and hardness, which are closely connected to the screen 7. Contact can effectively remove the clogging material in the mesh and ensure the transparency of the screen 7. The outer wall of the sliding column 19 is fitted with a spring 23. The two ends of the spring 23 are fixedly connected to the fixed plate 18 and the inside of the screen frame 2, respectively. When the push rod 20 is pushed to clean the screen 7, it is stretched. After cleaning, it can quickly drive the slide plate 21 and the cleaning brush 22 to reset without affecting the normal screening operation of the screen 7. The bottom of the screen frame 2 is fixedly connected to the discharge hopper 1 24, and the side of the screen frame 2 is fixedly connected to the discharge hopper 25, which are respectively for the discharge of materials of different particle sizes.

[0035] Working Principle: When using this vibrating linear screen for material screening, the material to be screened is first fed into the device through the feed hopper 5. The material falls onto the screen 7 inside the connecting frame 6. At this time, the vibrating motor 3 is started. The vibration force generated by the vibrating motor 3 is transmitted through the screening frame 2. With the cooperation of the vibration spring 4 between the support frame 1 and the screening frame 2, the screening frame 2 drives the connecting frame 6 and the screen 7 to perform linear vibration. The screen 7 screens the material. Material that meets the aperture size passes through the screen 7 and falls into the screening frame 2, and is finally discharged through the discharge hopper 24. Material that does not meet the aperture size remains on the screen 7 and moves to one side of the screening frame 2 with the vibration. The material is discharged through hopper 25. When the screen 7 needs to be disassembled, cleaned, or replaced, operate handle 16. Handle 16 drives sliding column 10 to slide inside fixed column 9. The mounting pin 11 at the bottom of sliding column 10 moves accordingly. At the same time, spring 14 on the outer wall of support column 13 inside mounting pin 11 pushes the retaining ball 15 to retract, so that mounting pin 11 can be pulled out from support frame 8, releasing the fixing between connecting frame 6 and support frame 8, and connecting frame 6 and screen 7 can be removed. During installation, align connecting frame 6 with support frame 8. Under the reset action of spring 12, sliding column 10 drives mounting pin 11 to insert into support frame 8, and retaining ball 15 pops out and locks in place, completing the fixing.

[0036] When the screen 7 needs to be cleaned during the vibrating screening process, the push-pull rod 20 is pushed to move. The push-pull rod 20 drives the slide plate 21 and cleaning brush 22 to move accordingly. The cleaning brush 22 contacts the screen 7 to clean the surface of the screen 7 and prevent the material from clogging the screen 7. At the same time, the spring 23 on the outer wall of the slide column 19 is stretched. After cleaning is completed, the spring 23 rebounds and drives the slide plate 21 to reset, continuously assisting the screen 7 to maintain a good screening state.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
