Description

Technical Field

[0001] This utility model relates to the field of flux recycling technology, specifically a vibrating sieving device for the development of nickel-based alloy submerged arc welding flux. Background Technology

[0002] Vibrating screens are solid particle separation devices that use vibration to force materials through a screen to achieve classification of different particle size components, removal of lumpy impurities, or screening out solid particles within the required particle size range. In the development of nickel-based alloy submerged arc welding fluxes, the main purpose of screening is to granulate the raw material powder, remove lumps and impurities, and provide a stable particle size distribution for formula weighing, mixing, and subsequent granulation; to ensure the fluidity, melting behavior, and compositional uniformity of the flux, thereby affecting the chemical composition of the weld pool and the weld microstructure.

[0003] For example, Chinese Patent No. CN221453392U discloses a submerged arc welding slag screening device, including: a shell; a rotary screen, rotatably connected inside the frame with its axis arranged horizontally; a power mechanism, with its output end connected to the rotary screen; a feed pipe, one end rotatably connected to the shell and the other end open and facing upward; a first screening box, located at the bottom of the shell; a baffle, located on the rotary screen at the end away from the feed pipe and having an air separation hole; a blower, with its outlet end connected to the feed pipe; an air separation pipe, with its inlet end rotatably connected to the baffle and covering the air separation hole; and a second screening box, located at the bottom of the air separation pipe. This device filters impurities contained in the submerged arc welding slag during the recycling process, specifically by using a blower to remove rust from the slag. This reduces the rust content in the recycled slag, lowers the impact of the recycled slag on the quality of the welded workpiece during use, and improves the welding quality of the welded workpiece.

[0004] Most of the existing technologies mentioned above improve the overall structure, while existing flux recovery devices are complex in structure, have high energy consumption and are inconvenient to maintain. Iron filings and impurities are difficult to remove completely, and impurities mixed into the flux can easily lead to welding defects. Utility Model Content

[0026] 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.

[0027] Example 1: Please refer to Figures 1 to 5 The present invention provides the following technical solution:

[0028] like Figures 1 to 4 As shown, a vibrating screening device for the development of nickel-based alloy submerged arc welding flux includes a mounting frame 1. A pretreatment component and a screening component are installed inside the mounting frame 1. The pretreatment component includes two magnetic rollers 2 rotatably connected to the upper inner side of the mounting frame 1. An isolation sleeve 3 is fitted on the outer side of one of the magnetic rollers 2. A driven roller 4 is also rotatably connected to the upper inner side of the mounting frame 1. A conveyor belt 5 is fitted on the outer side of the driven roller 4 and the other magnetic roller 2. A collection bin 7 is provided at the bottom of both magnetic rollers 2. The two collection bins 7 are located on the outer side of the isolation sleeve 3 and the outer side of the conveyor belt 5, respectively, and are in contact with the outer side of the isolation sleeve 3 or the outer side of the conveyor belt 5. A tension roller 6 is provided at the bottom of the conveyor belt 5, and the tension roller 6 is rotatably connected to the inner side of the mounting frame 1.

[0029] like Figure 4 As shown, both magnetic rollers 2 are fixedly connected to driven gears 11 at their ends, and the two driven gears 11 mesh with each other. One of the driven gears 11 is meshed with a drive gear 12 on its outer side, and the drive gear 12 is driven by a motor.

[0030] like Figure 5As shown, the top of the collection bin 7 is provided with a collection port 8, and the collection port 8 is attached to the outside of the isolation sleeve 3 or the conveyor belt 5. Multiple equally distributed scrapers 9 are fixedly connected to the inside of the collection port 8, and the scrapers 9 extend along the length of the collection port 8 and are attached to the outside of the isolation sleeve 3 or the conveyor belt 5.

[0031] like Figure 1 and Figure 2 As shown, the bottom of the collection bin 7 is set with an inclined structure, and the lower end of the bottom of the collection bin 7 is provided with a discharge port 10, which extends to the outside of the mounting frame 1. The top of the mounting frame 1 is fixedly connected with a feeding hopper 24, and the output end of the feeding hopper 24 is located at the top of the conveyor belt 5 away from the magnetic roller 2, and the output end of the conveyor belt 5 is located between the two magnetic rollers 2.

[0032] Material is added through the feeding hopper 24 and falls on the top of the conveyor belt 5 at the end away from the magnetic roller 2. The conveyor belt 5 is supported by the driven roller 4 and the magnetic roller 2, and is kept under appropriate tension by the tension roller 6 to ensure that the conveyor belt 5 does not slacken during operation. When the motor starts, the drive gear 12 rotates and drives the driven gear 11 that meshes with it to rotate. Since the two driven gears 11 mesh with each other, the two magnetic rollers 2 rotate synchronously in opposite directions, and the conveyor belt 5 moves accordingly, transporting the material between the two magnetic rollers 2.

[0033] During transportation, when the material passes through the area of ​​the magnetic roller 2, the magnetic material is attracted by the magnetic field of the magnetic roller 2. One of the magnetic rollers 2 is fitted with an isolation sleeve 3 on its outer side. The magnetic material is adsorbed onto the surface of the isolation sleeve 3 and rotates with it. The non-magnetic material continues to be carried by the conveyor belt 5. When the magnetic material rotates to the bottom with the isolation sleeve 3, the collection port 8 of the collection bin 7 is in contact with the outer side of the isolation sleeve 3, and multiple scrapers 9 are fixed on the inner side of the collection port 8. The scrapers 9 continuously scrape the surface of the isolation sleeve 3 as it rotates, scraping off the adsorbed magnetic material and guiding it into the collection bin 7. Similarly, the non-magnetic material detaches at the end of the conveyor belt 5 and falls into another collection bin 7. The collection port 8 of this collection bin 7 is also in contact with the outer side of the conveyor belt 5, and is scraped with the assistance of scrapers 9. The bottom of the collection bin 7 is designed with an inclined structure. The collected material slides towards the discharge port 10 at the lower end under the action of gravity and is finally discharged outside the mounting frame 1, completing the pre-treatment separation.

[0034] Example 2: Based on Example 1, please refer to... Figure 3 and Figure 6 The following structure was also disclosed:

[0035] like Figure 3As shown, the screening assembly includes a guide rail 13 fixedly connected to the inner side of the mounting frame 1, and two guide rails 13 are provided on both sides of the mounting frame 1, and the two guide rails 13 are horizontally parallel. A swing frame 14 is slidably connected between the four guide rails 13. A slider 15 is fixedly connected to the top and bottom of both ends of the swing frame 14, and the slider 15 is slidably connected to the outside of the guide rails 13.

[0036] like Figure 6 As shown, a first screen plate 16 is fixedly connected to the inner side of the swing frame 14, and the first screen plate 16 is provided with equidistantly distributed screening rods inside, and the screening rods are distributed along the length direction inside the first screen plate 16. The first screen plate 16 is inclined inside the driven roller 4, and the lower end of the first screen plate 16 is provided with an output end that extends to the outside of the mounting frame 1.

[0037] The bottom of the first screen plate 16 is provided with a first collection hopper 17. The bottom of the first collection hopper 17 is provided with a second screen plate 18 fixedly connected to the inner side of the swing frame 14. The second screen plate 18 is inclinedly distributed inside the driven roller 4, and the lower end of the second screen plate 18 is provided with an output end that extends to the outside of the mounting frame 1. The output end of the first collection hopper 17 is aligned with the highest point of the second screen plate 18. The bottom of the second screen plate 18 is fixedly connected with a second collection hopper 19. The bottom of the mounting frame 1 is fixedly connected with a guide trough 23. The bottom of the guide trough 23 is provided with an inclined structure, and the lower end of the bottom of the guide trough 23 is provided with an output port that extends to the outside of the mounting frame 1. The top of the guide trough 23 is aligned with the output end of the second collection hopper 19.

[0038] like Figure 3 As shown, a support beam 20 is fixedly connected to the bottom middle of the mounting frame 1, a vibration motor 21 is fixedly connected to the top of the support beam 20, a turntable is fixedly connected to the output end of the vibration motor 21, and a drive arm 22 is rotatably connected to the eccentric part of the turntable, and the end of the drive arm 22 away from the vibration motor 21 is rotatably connected to the bottom side of the driven roller 4.

[0039] The pre-treated material can fall into the screening assembly for grading and screening. The screening assembly includes a swing frame 14 that slides on a guide rail 13 via a slider 15. The guide rail 13 is fixed inside the mounting frame 1 to ensure that the swing frame 14 can move horizontally back and forth. The vibration motor 21 is fixed to the top of the support beam 20, and its output end drives the turntable to rotate. A drive arm 22 is rotatably connected to the eccentric part of the turntable. The other end of the drive arm 22 is rotatably connected to the bottom side of the driven roller 4. When the vibration motor 21 works, the eccentric rotation of the turntable is converted into reciprocating motion through the drive arm 22, thereby driving the driven roller 4 to vibrate. Since the driven roller 4 is indirectly connected to the swing frame 14, the swing frame 14 slides on the guide rail 13 and generates horizontal vibration.

[0040] The material first falls into the first screen plate 16 inside the swing frame 14. The first screen plate 16 is inclined and has equidistantly distributed screening rods inside. Under the vibration of the swing frame 14, the material moves along the inclined surface of the first screen plate 16 to the lower end. At the same time, the screening rods screen the material. Particles that meet the specifications fall into the first collection hopper 17 at the bottom through the gaps between the screening rods. Larger particles are discharged from the output end of the lower end of the first screen plate 16 to the outside of the mounting frame 1. The material collected in the first collection hopper 17 falls into the highest point of the second screen plate 18. The second screen plate 18 is also inclined and fixed inside the swing frame 14. Under the vibration, the material is further screened on the second screen plate 18. Finer particles fall into the second collection hopper 19 at the bottom through the second screen plate 18. The remaining material is discharged from the output end of the second screen plate 18. The material in the second collection hopper 19 falls into the guide trough 23. The bottom of the guide trough 23 is inclined. Under the action of gravity, the material is discharged from the output port to the outside of the mounting frame 1, realizing multi-stage screening.
