Description

Technical Field

[0001] This utility model relates to the field of gyratory screen technology, specifically a square gyratory screen feeding structure. Background Technology

[0002] The square screen consists of three main components: the inlet and outlet screens, the screen box, the vibration source, and the shock absorbers. The base is connected to the screen box by 4-6 sets of soft rubber shock absorbers fixed vertically. Centrifugal force is generated upon startup, and the amplitude is controlled by the eccentric blocks and shock absorbers to achieve optimal working performance. This allows the material to undergo a throwing and loosening process during screening, making it an ideal screening device widely applicable in industries such as pharmaceuticals, food, chemicals, metallurgy, and electronics.

[0003] Existing square gyratory screens mostly have only one feed inlet. When a large amount of material needs to be screened, a single feed inlet is insufficient to meet the demand. Furthermore, feeding different screens through a single feed inlet can easily lead to uneven feeding and a small feed volume, which is difficult to meet production needs. Therefore, a new square gyratory screen feeding structure is proposed. Utility Model Content

[0030] 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.

[0031] Please see Figure 1-4 This utility model provides a new technical solution: a square oscillating screen feeding structure, including a support frame 1, and four screen frames 2 are slidably connected to the inner surface of the top plate of the support frame 1;

[0032] The screen frame 2 is equipped with a screening mechanism, which includes a vibrating motor 3, a screen box 4, a discharge port 5, a conveying hopper 6, a feeding hopper 7, a conveying pipe 8, a connecting pipe 9, an L-shaped fixed plate 10, a drive motor 11, a first pulley 12, a belt 13, a second pulley 14, a threaded rod 15, a moving block 16, and a flow gravity head 17.

[0033] Furthermore, the screen box 4 is fixedly installed on the opposite sides of the four screen frames 2, and the vibration motor 3 is fixedly installed on the outer surface of the screen box 4;

[0034] Among them, six discharge ports 5 are fixedly installed on the right surface of the screen box 4.

[0035] Furthermore, six conveying hoppers 6 are fixedly installed on the left surface of the screen box 4, and three conveying pipes 8 are fixedly installed on the left surface of the six conveying hoppers 6;

[0036] Among them, the three feed hoppers 7 are fixedly installed at the upper ends of the three conveying pipes 8 respectively.

[0037] Furthermore, three L-shaped fixing plates 10 are respectively fixedly installed in the inner walls of the three conveying pipes 8;

[0038] Among them, the three connecting pipes 9 are fixedly installed on the outer surface of the three conveying pipes 8 respectively.

[0039] Furthermore, the three drive motors 11 are respectively fixedly installed in the inner wall of the three L-shaped fixing plates 10, and the three first pulleys 12 are respectively fixedly sleeved on the outer surface of the output shaft of the three drive motors 11.

[0040] The three belts 13 are respectively connected to the outer surfaces of the three first pulleys 12.

[0041] Furthermore, the three second pulleys 14 are respectively connected to the inner surfaces of the three belts 13, and the three threaded rods 15 are respectively fixedly sleeved on the inner surfaces of the three second pulleys 14.

[0042] The upper ends of the three threaded rods 15 are rotatably connected to the inner surfaces of the three L-shaped fixing plates 10.

[0043] Furthermore, the three movable blocks 16 are respectively threaded onto the outer surface of the three threaded rods 15, and the three movable blocks 16 are respectively slidably sleeved onto the inner surface of the vertical plates of the three L-shaped fixed plates 10.

[0044] Among them, three flow gravity heads 17 are fixedly installed on the lower surface of three moving blocks 16 respectively;

[0045] When using this square gyratory screen feeding structure, material is added to the three feed hoppers 7. The material then enters the conveying pipe 8 and flows through the feed hoppers 7 into the screen box 4. The vibration motor 3 is started, causing the screen box 4 to vibrate. After screening, the material is discharged from the discharge port 5. When simultaneous screening through six feed ports is required, the drive motor 11 is started. The drive motor 11 outputs power to the first pulley 12 fixedly mounted on the outer surface of the output shaft, causing it to rotate. Simultaneously, the first pulley 12 drives the outer surface... The belt 13 of the transmission connection rotates, and the belt 13 drives the second pulley 14 of the inner surface transmission connection to rotate. The second pulley 14 drives the threaded rod 15 fixedly sleeved on the inner surface to rotate. At this time, the moving block 16 of the threaded rod 15 on the outer surface of the threaded rod 15 moves continuously downward on the inner surface of the vertical plate of the L-shaped fixed plate 10 through the thread set on the outer surface of the threaded rod 15. At this time, the gap between the flow gravity head 17 and the conveying pipe 8 becomes larger, allowing the material to flow into another section of the conveying pipe 8 through the connecting pipe 9. It can enter the screen box 4 through the feed hopper 7 for material screening.

[0046] The square gyratory screen feeding structure can stop feeding by adjusting the flow rate through the drive motor 11 to close the gap between the gravity head 17 and the conveying pipe 8. By controlling the feeding speed of the material, the feeding can be made more uniform, which can effectively prevent the material from accumulating on the screen surface, thereby improving the screening performance. The square gyratory screen feeding structure, by setting six conveying hoppers 6, can simultaneously convey the six screen plates set in the screen box 4, increasing the feeding amount and improving the screening efficiency of the material, thus enabling high-efficiency production.
