[0001] This application relates to the field of metal waste screening technology, and in particular to a multi-stage screening machine for zinc slag. Background Technology

[0002] In the zinc smelting industry, the effective treatment of zinc dross is crucial. Zinc dross typically contains zinc metal, zinc oxide, and other impurities. Screening and separating it can recover valuable zinc resources, improve zinc recovery rates, and reduce production costs. However, existing zinc dross screening equipment has many shortcomings. For example, some equipment has low screening efficiency and cannot quickly and accurately separate zinc dross of different particle sizes, resulting in low production efficiency and affecting the entire zinc smelting process. Utility Model Content

[0003] This application provides a multi-stage zinc dross screening machine. The device is equipped with an inclined screening mechanism and a vibrator installed at the bottom of the screening mechanism. The three screens on the screening mechanism are driven to swing through a drive mechanism. At the same time, the vibrator vibrates, forming a double synergistic screening to improve screening efficiency. The device is equipped with a drive mechanism that drives the iron rod welded to its side wall to rotate through a rotating shaft. The connecting rod is driven by a bushing that is movably sleeved on the iron rod, thereby driving the three screens to swing and perform multi-stage screening of zinc dross on the screens. It achieves stable reciprocating swing drive and has a simple structure and is easy to maintain.

[0004] This application provides a multi-stage screening machine for zinc slag, comprising: a screening box and an air separation mechanism. The screening mechanism is installed inside the screening box, and a feed inlet is provided at the top of the screening box. The screening mechanism is suspended on two parallel crossbeams at the top of the screening box through four connecting mechanisms. A connecting rod is fixedly installed at the bottom of the screening mechanism, and a drive mechanism is connected to one end of the connecting rod. A vibrator is installed at the bottom of the screening mechanism. The top of the screening mechanism is connected to the air separation mechanism through a negative pressure pipe. Three screens are installed inside the screening mechanism, and each screen has a discharge port at its discharge end.

[0005] Furthermore, the screening mechanism is installed at an angle inside the screening box. Four rollers are installed at the bottom of the screening box's base plate, and a support rod is installed at each of the four corners of the base plate. Four crossbeams are welded to the top of the four support rods.

[0006] Furthermore, each connecting mechanism includes a fixed rod, a movable rod, and a fixed plate. A cylinder is welded to the bottom end of the fixed rod and the top end of the fixed plate, and a mounting clip is set at each end of the movable rod. The fixed rod is welded to the side wall of the crossbeam, and the fixed plate is welded to the side wall of the screening mechanism. The movable rod is movably connected to the cylinders of the fixed rod and the fixed plate through the mounting clips at both ends.

[0007] Furthermore, the drive mechanism includes a servo motor, a drive pulley, and a rotating shaft. The output end of the servo motor is connected to a drive main wheel, which is connected to the drive pulley via a belt. The drive pulley is connected to a rotating shaft, and an iron rod is welded to the side wall of one end of the rotating shaft. The iron rod is movably connected to a connecting rod via a bushing.

[0008] Furthermore, the air separation mechanism includes a fan and a dust collector. One end of the negative pressure pipe runs through the top of the screening box, and the other end of the negative pressure pipe is connected to the dust collector, which is connected to the fan.

[0009] Furthermore, three screens are installed in parallel within the screening mechanism, with the screen openings on the three screens decreasing in size from top to bottom.

[0010] As can be seen from the above technical solution, this application provides a screening box and an air separation mechanism. A screening mechanism is installed inside the screening box, and a feed inlet is provided at the top of the screening box. The screening mechanism is suspended from two parallel crossbeams at the top of the screening box via four connecting mechanisms. A connecting rod is fixedly installed at the bottom of the screening mechanism, with one end connected to a drive mechanism. A vibrator is installed at the bottom of the screening mechanism. The top of the screening mechanism is connected to the air separation mechanism via a negative pressure pipe. Three screens are installed inside the screening mechanism, each with a discharge port at its discharge end. The screening mechanism is installed at an angle inside the screening box, and the bottom plate of the screening box... The unit is equipped with four rollers, and a support rod is installed at each of the four corners of the base plate. Four crossbeams are welded to the tops of the four support rods. Each connecting mechanism includes a fixed rod, a movable rod, and a fixed plate. A cylinder is welded to the bottom of the fixed rod and the top of the fixed plate. A mounting clip is installed at each end of the movable rod. The fixed rod is welded to the side wall of the crossbeam, and the fixed plate is welded to the side wall of the screening mechanism. The movable rod movably connects the cylinders of the fixed rod and the fixed plate through the mounting clips at both ends. The drive mechanism includes a servo motor, a drive pulley, and a rotating shaft. The output end of the servo motor is connected to the main drive wheel, which is connected via a belt. A drive pulley is connected to a rotating shaft. An iron rod is welded to the side wall of one end of the shaft, and the iron rod is movably connected to a connecting rod via a bushing. The air separation mechanism includes a fan and a dust collector. One end of a negative pressure pipe passes through the top of the screening box, and the other end is connected to the dust collector, which is connected to the fan. Before screening the material, the servo motor is started, and an appropriate amount of zinc slag material to be screened is fed into the screening mechanism inside the screening box through the feed inlet. The servo motor drives the drive mechanism to start working, causing the screening mechanism to swing back and forth. Simultaneously, the vibrator is started, causing the screening mechanism to vibrate. Under the combined action of these two mechanisms... To improve screening efficiency, zinc dross continuously jumps and moves on the screen. Large zinc dross particles are first intercepted by the upper screen and discharged through the outlet. Medium-sized zinc dross particles pass through the upper screen, are intercepted by the middle screen, and are discharged. Fine zinc dross particles pass through the middle screen, are intercepted by the lower screen, and are discharged. Finally, the zinc dross that passes through the lower screen is discharged from one end of the bottom plate of the screening mechanism. During the screening process, the air separation mechanism works simultaneously. The negative pressure generated by the fan draws the dust in the zinc dross into the dust collector through the negative pressure pipe for treatment before being discharged, reducing environmental pollution.

[0011] In summary, the beneficial effects of this application are as follows: 1. The device is equipped with an inclined screening mechanism, and a vibrator is installed at the bottom of the screening mechanism. The three screens on the screening mechanism are driven by the drive mechanism to swing, and the vibrator vibrates at the same time, forming a double cooperative screening to improve screening efficiency.

[0012] 2. The device is equipped with a drive mechanism, which drives the iron rod welded to its side wall to rotate through the rotating shaft. The connecting rod is driven by the bushing that is movably sleeved on the iron rod, which in turn drives the three screens to swing back and forth to perform multi-stage screening of zinc dross on the screens. It achieves stable reciprocating swing drive, and the structure is simple and easy to maintain. Attached Figure Description

[0020] As can be seen from the above technical solutions, see [link / reference]. Figures 1-5 .

[0021] Example 1: A multi-stage zinc dross screening machine includes: a screening box 1 and an air separation mechanism. A screening mechanism 2 is installed inside the screening box 1. A feed inlet 13 is located at the top of the screening box 1. The zinc dross material to be screened is fed into the screening mechanism 2 inside the screening box 1 through the feed inlet 13. The screening mechanism 2 is suspended from two parallel crossbeams 4 at the top of the screening box 1 by four connecting mechanisms 5. A connecting rod 7 is fixedly installed at the bottom of the screening mechanism 2. A platform 6 is located at the bottom of the screening mechanism 2, and the connecting rod 7 is fixedly installed on the platform 6. One end of the connecting rod 7 is connected to a drive mechanism, which drives the connecting rod 7 to swing back and forth, thereby driving the screening mechanism 2 to swing back and forth to screen the zinc dross. A vibrator 17 is installed at the bottom of the screening mechanism 2. During the oscillating screening process of the screening mechanism 2, the vibrator 17 is simultaneously activated, driving the screening mechanism 2 to... Vibrating screening utilizes a drive mechanism and vibrator 17 to form a dual synergistic screening process, thereby improving screening efficiency. The top of the screening mechanism 2 is connected to an air separation mechanism via a negative pressure pipe 14. Dust generated during the screening process enters the air separation mechanism through the negative pressure pipe 14 for dust removal before being discharged, reducing the impact of dust on the environment. The screening mechanism 2 is equipped with three screens, each with a discharge port at its discharge end. The four discharge ports are staggered in direction and length to facilitate separate collection of the screened material. A corresponding receiving frame is placed below each discharge port. The screening mechanism 2 is driven to swing back and forth by the drive mechanism and vibrated by the vibrator 17, thereby using three screens with different apertures to perform multi-stage screening of zinc dross of different particle sizes, improving screening accuracy. The screened material is discharged along the discharge port connected to the end of each screen into the corresponding receiving frame.

[0022] In a preferred embodiment, the screening mechanism 2 is installed at an angle inside the screening box 1, so that the three screens installed on the screening mechanism 2 are installed at an angle as a whole, and the zinc dross is discharged from the outlet along with the inclined screens. Four rollers 18 are installed at the bottom of the bottom plate of the screening box 1, and the screening machine is moved by the four rollers 18, which is convenient and labor-saving. A support rod 3 is installed at each of the four corners of the bottom plate, and four crossbeams 4 are welded to the top of the four support rods 3. The screening mechanism 2 is supported and suspended by the four support rods 3 and the crossbeams 4.

[0023] In a preferred embodiment, each connecting mechanism 5 includes a fixed rod 51, a movable rod 52, and a fixed plate 53. A cylinder 54 is welded to the bottom end of the fixed rod 51 and the top end of the fixed plate 53, respectively. A mounting clip 520 is provided at both ends of the movable rod 52. The fixed rod 51 is welded to the side wall of the crossbeam 4, and the fixed plate 53 is welded to the side wall of the screening mechanism 2. The movable rod 52 is movably connected to the cylinders 54 of the fixed rod 51 and the fixed plate 53 through the mounting clips 520 at both ends. The screening mechanism 2 is suspended on the crossbeam 4 by the connecting mechanism 5. The driving mechanism drives the connecting rod 7 to move. The crossbeam 4 and the fixed rod 51 remain stationary. The screening mechanism 2 and the fixed plate 53 swing with the connecting rod 7 and the screening mechanism 2. The movable rod 52 between the fixed rod 51 and the fixed plate 53 drives the screening mechanism 2 to swing back and forth to screen the material.

[0024] In a preferred embodiment, the drive mechanism includes a servo motor 12, a drive pulley 11, and a rotating shaft 10. The output end of the servo motor 12 is connected to a drive main wheel, which is connected to the drive pulley 11 via a belt. The drive pulley 11 is connected to a rotating shaft 10, which passes through a bearing seat fixed on a support rod 3. An iron rod 9 is welded to the side wall of one end of the rotating shaft 10. The iron rod 9 is movably connected to a connecting rod 7 via a bushing 8. The end of the connecting rod 7 away from the bottom of the connecting screening box 1 is fixedly connected to the bushing 8, which movably sleeves the iron rod 9 on the side wall of the rotating shaft 10. The servo motor 12 is connected to... When the power is connected and materials are being screened, the servo motor 12 is started. The servo motor 12 drives the connected drive main wheel to rotate, which in turn drives the drive pulley 11 to rotate via the belt. This, in turn, drives the rotating shaft 10 and the iron rod 9 on the side wall of the rotating shaft 10 to rotate. The connecting rod 7 is movably sleeved on the bushing 8 of the iron rod 9 and swings back and forth with the rotation of the rotating shaft 10, thereby driving the screening mechanism 2 to swing back and forth to screen the materials. The side wall of the screening box 1 has openings corresponding to the positions of the drive pulley 11 and the rotating shaft 10, which facilitates the drive mechanism to drive the screening mechanism 2 to achieve stable reciprocating swing. The structure is simple and easy to maintain.

[0025] In a preferred embodiment, the air separation mechanism includes a fan 16 and a dust collector 15. One end of a negative pressure pipe 14 passes through the top of the screening box 1, and the other end of the negative pressure pipe 14 is connected to the dust collector 15. The dust collector 15 is connected to the fan 16. During the screening process, the fan 16 and the dust collector 15 are started. The dust generated by the zinc dross during the screening process is introduced into the dust collector 15 through the negative pressure pipe 14 by the negative pressure generated by the fan 16 for dust removal, and then discharged to prevent the dust from being directly discharged into the air during the screening process and causing environmental impact.

[0026] In a preferred embodiment, three screens are installed in parallel within the screening mechanism 2. The screen openings on the three screens decrease in size from top to bottom. The three screens with different opening diameters classify and screen the zinc dross material, thereby improving the screening accuracy and facilitating subsequent resource utilization.

[0027] Working principle: Before screening the material, the servo motor 12 is started, and an appropriate amount of zinc dross material to be screened is fed into the screening mechanism 2 in the screening box 1 through the feed port 13. The servo motor 12 drives the drive mechanism to start working, causing the screening mechanism 2 to swing back and forth. At the same time, the vibrator 17 is started, causing the screening mechanism 2 to vibrate. Under the dual synergistic effect, the screening efficiency is improved. The zinc dross jumps and moves continuously on the screen. Large particles of zinc dross are first intercepted by the upper screen and discharged through the discharge port. Medium particles of zinc dross are intercepted and discharged by the middle screen after passing through the upper screen. Fine particles of zinc dross are intercepted and discharged by the lower screen after passing through the middle screen. Finally, the zinc dross that passes through the lower screen is discharged from one end of the bottom plate of the screening mechanism 2. During the screening process, the air separation mechanism works simultaneously. The negative pressure generated by the fan 16 draws the dust in the zinc dross into the dust collector 15 through the negative pressure pipe 14 for treatment before being discharged, reducing pollution to the environment.
