Description

Technical Field

[0001] This utility model relates to the field of zinc powder production technology, specifically to a multi-stage zinc powder grading system. Background Technology

[0002] Zinc powder is a dark gray powdery metal and an important raw material in modern industry. For zinc powder produced by ball milling, even with the same processing parameters, the particle size varies. Furthermore, different industrial sectors require zinc powder with different particle diameters. Therefore, zinc powder screening is necessary. Among them, CN215784740U discloses a zinc powder grading device, including: a screw feeder arranged on the upper left side of a tank; a multi-stage filter screen arranged inside the tank; a waste outlet arranged on the left side of the tank; and multiple discharge outlets arranged on the right side of the tank. The multi-stage filter screen includes at least: a first filter screen inclined to the right and lower on the left below the screw feeder; a second filter screen inclined to the left and lower on the right below the first filter screen, with its left side connected to a vibrating motor via a transmission connecting rod, and its right side arranged above the lower edge of the first discharge outlet of the tank; and a third filter screen arranged in the same direction as the second filter screen, with its left side connected to the transmission connecting rod and its right side arranged above the lower edge of the second discharge outlet of the tank. The vibrating motor drives the second and third filter screens to vibrate; and multiple filter brushes arranged side by side are respectively arranged above the second and third filter screens. The technical solution in this application optimizes the zinc powder grading efficiency and grading effect, and reduces the labor cost in the zinc powder grading process.

[0003] However, in actual use, the device discharges the material directly onto the surface of the first filter screen through the screw feeder, and the material falls at basically the same position, which easily causes zinc powder to accumulate. This causes the zinc powder to get stuck on the upper side of the first filter screen, affecting the filtration speed. Furthermore, excessive accumulation can cause some small zinc powder particles to slide into the waste bin, resulting in waste of zinc powder.

[0004] Therefore, it is necessary to invent a multi-stage zinc powder classification system to solve the above problems. Utility Model Content

[0018] Optionally, a support frame is fixedly connected to the side of the connector, and the two ends of the support frame are fixedly connected to the surface of the equipment housing.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 5 The multi-stage zinc powder grading system shown includes a filter box 1. Multiple sets of vibrating screen plates 11 are fixedly installed inside the filter box 1. A vibrating guide plate 12 is fixedly connected to the lower side of the vibrating screen plates 11 inside the filter box 1. Discharge troughs 13 are provided on the right side surface of the filter box 1 at the right ends of both the multiple sets of vibrating screen plates 11 and the vibrating guide plate 12. A collection box 14 is fixedly connected to the right side of the discharge trough 13. A feed cylinder 2 is fixedly connected to the upper end of the filter box 1. A mounting base 21 is fixedly installed on the upper end of the feed cylinder 2. A material leveling component is provided on the surface of the mounting base 21. The material leveling component includes an electric motor 23, a connector 25, a connecting cylinder 26, an electromagnet 27, a spiral feed pipe 28, a guide pipe 29, a rotary joint 210, a diverter pipe 211, a guide hole 212, a first gear 213, and a second gear 214.

[0027] The vibrating screen plate 11 and the vibrating guide plate 12 are both inclinedly arranged inside the filter box 1. The size of the screen holes of the multiple sets of vibrating screen plates 11 gradually decreases from top to bottom, which is used to screen zinc powder of different particle sizes. The vibrating guide plate 12 is used to discharge the smallest zinc powder particles.

[0028] During use, the zinc powder is fed using the uniform feeding component, and the zinc powder is evenly spread on the surface of the uppermost vibrating screen plate 11. Multiple sets of vibrating screen plates 11 screen and filter the zinc powder once. The smallest zinc powder particles will fall into the interior of the vibrating guide plate 12. The vibrating screen plate 11 and the vibrating guide plate 12 move the zinc powder to the right during vibration. The screened zinc powder is discharged into the collection box 14 through the discharge chute 13 and then pumped out through the conveying pipe on the lower side.

[0029] See Figures 3 to 5The feed tube 29 is rotatably connected to the interior of the mounting base 21. Two branch pipes 211 are fixedly connected to the lower end of the feed tube 29. Multiple feed holes 212 are opened on the lower side of each branch pipe 211. The rotary joint 210 is fixedly connected to the upper end of the feed tube 29. The connector 25 is rotatably connected to the rotary joint 210. The connecting cylinder 26 is fixedly connected to the upper end of the connector 25. The electromagnet 27 is fixedly installed in a ring shape inside the connecting cylinder 26. The spiral feed tube 28 is fixedly connected to the upper end of the connecting cylinder 26. The first gear 213 is fixedly connected to the upper end of the guide tube 29, and the second gear 214 is meshed with the side of the first gear 213. A device housing 22 is installed on the outer side of the first gear 213 and the second gear 214. The electric motor 23 is fixedly installed on the upper side of the device housing 22, and the output end of the electric motor 23 is fixedly connected to the shaft of the second gear 214. A support frame 24 is fixedly connected to the side of the connector 25, and both ends of the support frame 24 are fixedly connected to the surface of the device housing 22.

[0030] Specifically, when feeding zinc powder, the spiral feed pipe 28 conveys the zinc powder through the connecting cylinder 26 and the connecting head 25 to the inside of the guide pipe 29. The guide pipe 29 guides the zinc powder into the inside of the two diversion pipes 211. At the same time, the electric motor 23 drives the second gear 214 to rotate, the second gear 214 drives the first gear 213 to rotate, the first gear 213 drives the guide pipe 29 to rotate, and the guide pipe 29 drives the diversion pipes 211 to rotate. As the diversion pipes 211 rotate, under the action of centrifugal force, the zinc powder is discharged through multiple sets of guide holes 212, so that the zinc powder is evenly spread on the surface of the uppermost vibrating screen plate 11.

[0031] Meanwhile, when the spiral feed pipe 28 is feeding material, the material will pass through the inside of the connecting cylinder 26. At this time, the electromagnet 27 inside the connecting cylinder 26 will attract the iron filings in the zinc powder to maintain the purity of the zinc powder. When a lot of iron filings are attracted and affect the feeding, after disassembling multiple sets of screws, the connecting cylinder 26 can be removed. At this time, the electromagnet 27 is de-energized, so that the magnetism of the electromagnet 27 disappears. At this time, the iron filings attracted on its surface will fall off automatically, making it easy to clean.

[0032] The working principle of this utility model is as follows: By using the material distribution component, zinc powder is evenly sprinkled onto the surface of the uppermost vibrating screen plate 11, which improves the uniformity of zinc powder and avoids zinc powder accumulation. The vibrating screen plate 11 is used to vibrate and screen the zinc powder, so that it can be quickly filtered to the lower side, improving the filtration efficiency. At the same time, it prevents small zinc powder particles from sliding into the waste collection box 14 on the right side, improving the screening effect and avoiding waste.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
