Description

Technical Field

[0001] This utility model belongs to the field of metal smelting technology, specifically referring to a zinc alloy smelting slag separation device. Background Technology

[0002] The slag produced during zinc alloy smelting contains a large amount of recyclable zinc and other valuable metals. Separating and recycling the slag can not only improve economic value and reduce costs, but also achieve good environmental benefits. Traditional manual slag removal and separation methods are labor-intensive, have unstable cleaning effects, and are prone to safety hazards. Therefore, people have adopted vacuum separation furnaces to melt and separate zinc slag into low-iron zinc liquid and high-iron zinc slag by controlling the temperature gradient and agglomeration.

[0003] Existing vacuum separation furnaces for zinc alloy smelting slag lack the function of crushing and screening zinc slag during use, resulting in zinc slag of varying sizes. This makes it impossible to ensure uniform particle size of the slag, which in turn leads to uneven heating during melting and affects the smelting effect. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a zinc alloy smelting slag separation device, which effectively solves the problem that the smelting effect is easily affected by the uneven particle size of the slag in the existing zinc alloy smelting slag vacuum separation furnace during smelting.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a zinc alloy smelting slag separation device, including a working platform, which is parallel to the ground and fixed by welding steel structure. A base plate is horizontally provided on the ground at the lower end of the working platform. A tilting mechanism is provided on the base plate, and a vacuum separation furnace is connected to the tilting mechanism. The upper end of the vacuum separation furnace is set through the working platform. Two symmetrical supports are vertically fixed on the working platform on both sides of the vacuum separation furnace. A crushing barrel is fixed on the support, and a multi-stage crushing mechanism is connected to the crushing barrel. The multi-stage crushing mechanism includes a square-to-round flange fixed to the upper end of the crushing barrel, and a feeding hopper is fixed to the upper end of the square-to-round flange. Two symmetrical crushing rollers are rotatably connected inside the feeding hopper. A coaxial drive assembly is connected to the inner wall of the crushing barrel, and a slag crushing rod is connected to the coaxial drive assembly.

[0006] As an improvement to this solution, the coaxial drive assembly consists of a guide shell, a rotating drum, and a rotating shaft. The guide shell is coaxially fixed inside the crushing drum, and the rotating drum is rotatably connected to the bottom of the guide shell and extends through it into the crushing drum. The crushing rods are evenly distributed on the side walls of the rotating drum. The rotating shaft extends through the rotating drum, and its upper end is rotatably connected to the top of the guide shell. A planetary gear set is located at the top of the rotating shaft. The sun gear of the planetary gear set is fixed to the rotating shaft, and the planet gears and the internal gear ring of the planetary gear set are rotatably connected to the top of the guide shell. The three sets of planetary gears are evenly arranged around the rotating shaft.

[0007] As an improvement to this solution, the bottom of the internal gear ring of the planetary gear set and the upper end of the rotating drum are both fixed with driven bevel gears, and a drive motor is fixed at the bottom of the material guide protective shell on one side of the two driven bevel gears. The output end of the drive motor is connected to the driving bevel gear, and the driving bevel gear meshes with the two driven bevel gears.

[0008] As an improvement to this solution, a vibrating screening assembly is connected to the bottom of the rotating shaft. The vibrating screening assembly includes a screen plate slidably connected to the inner wall of the crushing barrel, and a hollow guide cylinder is fixed at the bottom of the screen plate. Two spiral slide rails are centrally symmetrically distributed on the inner wall of the guide cylinder and slide relative to two drive slide rods symmetrically fixed on the side wall of the rotating shaft. A return spring is fixed on the drive slide rod, and the other end of the return spring is arranged around the rotating shaft and below the screen plate.

[0009] As an improvement to this solution, the tilting mechanism includes a support rod vertically fixed to the base plate, and the support rods are symmetrically distributed on both sides of the vacuum separator. A rotating rod is fixed in the middle of the side wall of the vacuum separator, and the vacuum separator is rotatably connected to the support rod through the rotating rod. A rocker arm is fixed to one end of the rotating rod that passes through the support rod. A hydraulic cylinder is rotatably connected to the base plate, and the output end of the hydraulic cylinder is connected to the movable end of the rocker arm.

[0010] As an improvement to this solution, a cooling tank is plugged into the upper end of the vacuum separator. A sealing cover is fixed to the outer side of the cooling tank at the upper end of the vacuum separator by bolts. Two lifting lugs are symmetrically provided at the upper end of the sealing cover, and the sealing cover is located below the crushing barrel. A clamping plate is fixed to the working platform by bolts, and the side wall of the vacuum separator is clamped to the working platform by the clamping plate.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. Through the multi-stage crushing structure, the vibration components inside the crushing barrel, combined with the crushing rod with spiral spikes, can effectively ensure the uniform particle size of the slag, significantly improve the separation efficiency and metal recovery rate, and reduce the energy consumption of subsequent smelting.

[0013] 2. The entire process is automated. After feeding, the slag is crushed and screened by a multi-stage crushing structure and then falls into the vacuum separation furnace. The cooling tank and sealing cover are then installed by external hoisting equipment. Finally, the slag is dumped by a tilting mechanism. The entire process from feeding, crushing and smelting is basically automated, reducing manual intervention and improving the safety and stability of operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 and Figure 2 As shown, the present invention proposes a zinc alloy smelting slag separation device, including a working platform 1, which is parallel to the ground and fixed by welding steel structure. A base plate 2 is horizontally provided on the ground at the lower end of the working platform 1. A tilting mechanism 3 is provided on the base plate 2, and a vacuum separation furnace 4 is connected to the tilting mechanism 3. The upper end of the vacuum separation furnace 4 is set through the working platform 1. Two symmetrical supports 5 are vertically fixed on the working platform 1 on both sides of the vacuum separation furnace 4. A crushing barrel 6 is fixed on the support 5, and a multi-stage crushing mechanism 7 is connected to the crushing barrel 6.

[0024] like Figure 2 and Figure 4 As shown, the multi-stage crushing mechanism 7 includes a square-to-round flange 8 fixed at the upper end of the crushing barrel 6, and a feeding hopper 9 fixed at the upper end of the square-to-round flange 8. Two symmetrical crushing rollers 10 are rotatably connected inside the feeding hopper 9. A coaxial drive assembly 11 is connected to the inner wall of the crushing barrel 6, and a crushing rod 24 is connected to the coaxial drive assembly 11.

[0025] The multi-stage crushing mechanism 7 can fully crush the slag material evenly, so as to improve the efficiency and effect of subsequent melting in the vacuum separation furnace 4.

[0026] like Figure 3 and Figure 6 As shown, in order to drive the multi-stage crushing mechanism 7, the coaxial drive assembly 11 consists of a material guide protective shell 12, a rotating drum 13, and a rotating shaft 14. The material guide protective shell 12 is coaxially fixed inside the crushing barrel 6, and the rotating drum 13 is rotatably connected to the bottom of the material guide protective shell 12 and passes through the material guide protective shell 12 inside the crushing barrel 6. The crushing rods 24 are evenly distributed on the side wall of the rotating drum 13. Meanwhile, the rotating shaft 14 passes through the rotating drum 13, and the upper end of the rotating shaft 14 is rotatably connected to the top inside the material guide protective shell 12.

[0027] A planetary gear set 15 is provided at the top inside the rotating shaft 14. The sun gear of the planetary gear set 15 is fixed on the rotating shaft 14. The planet gears and the internal gear ring of the planetary gear set 15 are rotatably connected to the top inside the guide protective shell 12. The three sets of planetary gears are evenly arranged around the rotating shaft 14.

[0028] like Figure 3As shown, driven bevel gears 16 are fixed at the bottom of the internal gear ring of the planetary gear set 15 and the upper end of the rotating drum 13. A drive motor 25 is fixed at the bottom of the material guide protective shell 12 on one side of the two driven bevel gears 16. The output end of the drive motor 25 is connected to the driving bevel gear 17, which meshes with the two driven bevel gears 16.

[0029] like Figure 2 and Figure 6 As shown, in order to achieve the crushing process, a vibrating screen assembly 18 is connected to the bottom of the rotating shaft 14. The vibrating screen assembly 18 includes a screen plate 19 slidably connected to the inner wall of the crushing barrel 6, and a hollow guide cylinder 20 is fixed at the bottom of the screen plate 19. Two spiral slide rails 21 are centrally symmetrically distributed on the inner wall of the guide cylinder 20 and slide relative to two drive slide rods 22 symmetrically fixed on the side wall of the rotating shaft 14. A return spring 23 is fixed on the drive slide rod 22, and the other end of the return spring 23 is arranged around the rotating shaft 14 and below the screen plate 19.

[0030] like Figure 5 As shown, in order to facilitate the dumping and cleaning of slag, the dumping mechanism 3 includes a support rod 26 that is vertically fixed on the base plate 2, and the support rod 26 is symmetrically distributed on both sides of the vacuum separator 4. A rotating rod 27 is fixed in the middle of the side wall of the vacuum separator 4, and the vacuum separator 4 is rotatably connected to the support rod 26 through the rotating rod 27. A rocker arm 28 is fixed at one end of the rotating rod 27 that passes through the support rod 26. A hydraulic cylinder 29 is rotatably connected on the base plate 2, and the output end of the hydraulic cylinder 29 is connected to the movable end of the rocker arm 28.

[0031] like Figure 2 , Figure 4 and Figure 5 As shown, a cooling tank 30 is plugged into the upper end of the vacuum separator 4. A sealing cover 31 is fixed to the outer side of the cooling tank 30 at the upper end of the vacuum separator 4 by bolts. Two lifting lugs are symmetrically provided at the upper end of the sealing cover 31, and the sealing cover 31 is located below the crushing barrel 6. A clamping plate 32 is fixed to the working platform 1 by bolts, and the side wall of the vacuum separator 4 is clamped to the working platform 1 by the clamping plate 32.

[0032] In practical use, the slag is fed from above the hopper 9 by walking on the working platform 1, and the crushing rollers 10 (existing technology) are turned on to rotate relative to each other, so that the slag is initially crushed and then fed into the crushing barrel 6 through the square-to-round flange 8. At the same time, the drive motor 25 is turned on to drive the active bevel gear 17 to rotate, so that the two driven bevel gears 16 meshing with it drive the rotating drum 13 and the rotating shaft 14 to rotate after being reduced by the planetary gear set 15. As the rotating drum 13 rotates, the crushing rods 24 on the side wall of the rotating drum 13 further crush the initially crushed slag, and after being screened and filtered by the screen plate 19, it enters the vacuum separation furnace 4. As the rotating shaft 14 rotates, the drive slide rods 22 fixed to the bottom of both sides of the rotating shaft 14 slide along the spiral slide rail 21. At this time, since the screen plate 19 is slidably connected to the inner wall of the crushing barrel 6 (the screen plate 19 is symmetrically provided with rectangular slide grooves, and the inner wall of the crushing barrel 6 is provided with matching rectangular guide rails), under the reaction force, the spiral slide rail 21 drives the guide cylinder 20 and The screen plate 19 on it tends to move upwards, and after the spiral slide rail 21 separates from the drive slide rod 22, it is reset by the return spring 23, thereby realizing the vertical vibration of the screen plate 19, screening the slag above it, and sending the larger slag filtered down to the bottom slag crushing rod 24 for crushing. After the slag is crushed and screened, it enters the vacuum separation furnace 4. The cooling tank 30 is inserted into the upper end of the vacuum separation furnace 4, and then the sealing cover 31 is lifted by the external hoisting equipment and inserted into the upper end of the vacuum separation furnace 4 after the cooling tank 30 is aligned. Then it is fixed with bolts, and the slag can be smelted in the vacuum separation furnace 4. The vaporized slag is cooled and collected in the cooling tank 30. After opening the sealing cover 31, the cooling tank 30 can be taken out. Then the clamping plate 32 is removed, and then the hydraulic cylinder 29 extends to push the rocker arm 28 to drive the rotating rod 27 to rotate, so that the vacuum separation furnace 4 tilts to one side of the clamping plate 32. The above is the entire process of using the zinc alloy smelting slag separation device.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
