Description

Technical Field

[0001] The present invention relates to the field of non-ferrous metal smelting, and specifically to a feeding device for non-ferrous metal smelting. Background Art

[0002] Non-ferrous metal smelting is a production process of separating associated elements from ores, concentrates, secondary resources or other materials to produce non-ferrous metals or their compounds. During the non-ferrous metal smelting process, materials need to be added to a high-temperature smelting furnace. The temperature of the smelting furnace is extremely high during smelting. Therefore, manual feeding near the smelting furnace not only has a high labor intensity but also is extremely prone to danger. Prolonged proximity to the operation is also a burden on the human body. For this reason, mechanical feeding is required.

[0003] Currently, during non-ferrous metal smelting, some are for separating secondary resources, and some are for separating ores. When separating associated elements from secondary resources and ores separately to produce non-ferrous metals, most are single-to-single feeding. For example, the utility model patent with the patent document number CN219057904U discloses a feeding device for non-ferrous metal smelting, and the utility model patent with the patent document number CN217636778U discloses a feeding device for non-ferrous metal smelting. As the above-mentioned disclosed patents, when in use, one feeding device is used corresponding to one smelting furnace for smelting, and such feeding devices will use some driving devices to drive the feeding structure for feeding. The driving devices consume electricity. Two feeding devices for feeding require two driving devices to drive, which is not conducive to energy conservation and environmental protection. Summary of the Invention

The front and rear ends of the conveyor belt are fixedly connected to the synchronous belt.

[0009] Preferably, a plurality of limiting plates are horizontally and equidistantly fixed on one side of the upper surface of the synchronous belt.

[0010] Preferably, the synchronous drive mechanism includes an upper worm and worm gear reducer, a lower worm and worm gear reducer, and a double-shaft motor. The double-shaft motor is fixedly installed on the support frame. The lower worm and worm gear reducer is located below the double-shaft motor and is fixedly installed on the support frame. The lower output shaft of the double-shaft motor is connected to the input shaft of the lower worm and worm gear reducer.

[0011] Preferably, the upper worm and worm gear reducer is fixed to the front end of the blanking frame. The upper output shaft of the double-shaft motor is connected to the input shaft of the upper worm and worm gear reducer.

[0012] Preferably, the bevel gear mechanism includes a driven bevel gear, a horizontal shaft rod, and a driving bevel gear. The driven bevel gear is fixed to the lower part of the vertical shaft rod. The driven bevel gear is located below the baffle plate. The driving bevel gear is meshed and connected to the front of the driven bevel gear. The horizontal shaft rod is fixed to the front end of the driving bevel gear. The front end of the horizontal shaft rod is connected to the output shaft of the upper worm and worm gear reducer.

[0013] Preferably, a transformer is fixed to the rear end of the blanking frame, generators are fixedly installed on both the left and right sides of the rear part of the side plate at the rear side, the rear part of the rotating shaft penetrates through the side plate, the rear part of the rotating shaft is connected to the input shaft of the generator, the generator is electrically connected to the transformer, and the transformer is electrically connected to the arc-shaped electronically controlled dimming glass.

[0014] Preferably, a plurality of horn-shaped rubber covers are fixedly sleeved on the outer part of the main pulling rope at equal intervals. Reserved holes are provided on the surfaces of the left and right arc-shaped electronically controlled dimming glasses. An I-shaped sleeve is fixed inside the reserved holes. The main pulling rope is inserted into the I-shaped sleeve. A plurality of fan-shaped rubber sheets are fixedly arranged at equal intervals in a circular shape on the inner walls of the two openings of the I-shaped sleeve. The main pulling rope is located between the inner sides of the fan-shaped rubber sheets. The outer diameter of one end of the rubber cover is larger than the inner diameter of the I-shaped sleeve, and the outer diameter of the other end of the rubber cover is equal to the inner diameter of the I-shaped sleeve.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The inner part of the glass cylinder is separated into two separate spaces on the left and right by the arc-shaped spring metal sheet. In this way, the ore powder and secondary resources can be placed in the two spaces respectively. Then, when the conveying component is tilted to the left by the synchronous drive mechanism, the bottom of the left space is opened, while the bottom of the right space is blocked by the baffle plate. At the same time, the conveying component pulls the arc-shaped spring metal sheet to concave to the left through the main pulling rope. At this time, the right space increases, which is convenient for storing materials. The left space is squeezed by the arc-shaped spring metal sheet, playing a role in loosening the materials to prevent blockage. Finally, the materials in the left space fall onto the conveying component and are conveyed to the left for feeding work. When the conveying component is tilted to the right, the materials in the right space can be added to another smelting furnace. In this way, one feeding device can be used for two smelting furnaces respectively, improving the practicability and facilitating the staff.

[0017] 2. When the conveying component is tilted towards one side, due to the center of gravity shifting towards one side, at this time, the steel ball will push the limiting plate, and the limiting plate drives the synchronous belt to move. In this way, the synchronous belt drives the conveyor belt to move, so as to actively drive the conveyor belt to drive the ore powder or secondary resources for feeding without electric power driving the synchronous belt. And the whole device uses a single double-shaft motor connected to an external power supply, which can play the role of energy conservation and environmental protection.

[0018] 3. When the synchronous belt moves, the synchronous pulley can also move. In this way, the movement of the synchronous pulley drives the input shaft of the generator to rotate through the rotating shaft, so as to generate electricity. Then, the voltage is changed to a suitable voltage for the arc-shaped electronically controlled dimming glass through a transformer, and the arc-shaped electronically controlled dimming glass can be powered on. Because when the arc-shaped electronically controlled dimming glass is powered off, the liquid crystal molecules inside the arc-shaped electronically controlled dimming glass will show an irregular dispersion state. At this time, the arc-shaped electronically controlled dimming glass presents a translucent and opaque appearance state. When the arc-shaped electronically controlled dimming glass is powered on, the liquid crystal molecules inside are neatly arranged and the light can penetrate freely. At this time, the arc-shaped electronically controlled dimming glass instantly presents a transparent state, which is convenient for the staff to judge the amount of materials inside the glass barrel and improves the sense of technology at the same time;

[0019] 4. When the main pull rope moves, it can move along the I-shaped sleeve, thereby driving the horn-shaped rubber cover through the inside of the I-shaped sleeve. The cooperation between the horn-shaped rubber cover and the fan-shaped rubber sheet can not only improve the sealing performance between the main pull rope and the glass barrel, but also make the main pull rope vibrate slightly every time the rubber cover moves out of the I-shaped sleeve. And the material surrounds the outside of the main pull rope, which can play a role in vibrating the materials inside the glass barrel. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0028] Please refer to Figures 1-7 , a feeding device for non-ferrous metal smelting, including a blanking frame 1 and a support frame 7. Support frames 7 are fixedly arranged on the front and rear sides of the lower end of the blanking frame 1. A glass cylinder 2 is fixedly arranged at the upper end of the blanking frame 1. An arc spring metal sheet 3 is fixedly arranged in the middle of the inner part of the glass cylinder 2. An intermediate table 15 is fixedly arranged in the blanking frame 1. A cylinder groove 14 is formed at the upper end of the blanking frame 1. The glass cylinder 2 is fixedly arranged inside the cylinder groove 14. The glass cylinder 2 is composed of four arc-shaped electrochromic glasses fixedly connected to each other. The front and rear ends of the arc spring metal sheet 3 are fixedly connected to the front and rear arc-shaped electrochromic glasses. The lower part of the arc spring metal sheet 3 is in close contact with the upper part of the intermediate table 15. A vertical shaft rod 17 is connected to the middle of the intermediate table 15 through a bearing. A baffle plate 16 located below the intermediate table 15 is fixedly arranged at the lower part of the vertical shaft rod 17. The arc spring metal sheet 3 is used to divide the inner part of the glass cylinder 2 into two independent spaces on the left and right. The baffle plate 16 can rotate below the intermediate table 15 through the vertical shaft rod 17 to block the bottom of one of the spaces.

[0029] A conveying component is rotatably connected between the support frames 7. The conveying component includes side plates 11, a conveyor belt 13 and a support table 23. There are a pair of side plates 11 which are distributed front and rear. The sub-pulling rope 6 is fixedly connected to the side plates 11. A rotating shaft is fixedly arranged in the middle of the ends of the side plates 11 away from each other. The end of the rotating shaft penetrates through the support frame 7 and is rotatably connected to the support frame 7. Grooves 22 are arranged at the ends of the side plates 11 close to each other. A support table 23 is fixedly arranged in the middle of the bottom of the grooves 22. The conveyor belt 13 is movably sleeved outside the support table 23. The materials in the space whose bottom is blocked by the baffle plate 16 cannot fall, while the materials in the space whose bottom is not blocked by the baffle plate 16 will fall onto the conveyor belt 13 and the conveyor belt 13 is supported by the support table 23. In this way, if the side plates 11 are tilted to make the conveyor belt 13 tilted, the materials on the conveyor belt 13 can be tilted and conveyed.

[0030] The bottom of the groove 22 is connected to a rotating shaft 24 with bearings on both sides, and a T-shaped synchronous wheel 25 is fixed on the outside of the rotating shaft 24. A synchronous belt 26 is connected between the synchronous wheels 25 on the same horizontal line on the left and right sides. The front and rear ends of the conveyor belt 13 are fixedly connected to the synchronous belt 26. A plurality of limit plates 27 are fixed horizontally and equidistantly on one side of the upper surface of the synchronous belt 26. The limit plates 27 are provided with arc grooves on both ends, and a steel ball 28 is provided between two adjacent arc grooves. A rolling groove is opened at the top of the inner part of the groove 22, and the upper part of the steel ball 28 is located in the rolling groove. The steel ball 28 is connected to the side plate 11 in a rolling manner and is connected to the rolling groove inside. When the side plate 11 is tilted, the steel ball 28 will roll along the rolling groove toward the tilted side. The setting of the rolling groove can guide and limit the steel ball 28. At the same time, the steel ball 28 is limited front and back inside the arc groove of the two adjacent limiting plates 27, so that the steel ball 28 will not move out from between the two adjacent limiting plates 27. In this way, the steel ball 28 rolling toward the tilted side will push the limiting plate 27, so that the limiting plate 27 drives the synchronous belt 26, and the synchronous wheel 25 rotates, and the synchronous belt 26 can drive the conveyor belt 13 to move at the same time.

[0031] A synchronous drive mechanism is installed between the front of the support frame 7 and the front of the blanking frame 1, and the rear of the synchronous drive mechanism is connected to the conveying assembly. The synchronous drive mechanism includes an upper worm gear reducer 8, a lower worm gear reducer 9 and a double-axis motor 10. The double-axis motor 10 is fixedly installed on the support frame 7, and the lower worm gear reducer 9 is located below the double-axis motor 10 and is fixedly installed on the support frame 7. The lower output shaft of the double-axis motor 10 is connected to the input shaft of the lower worm gear reducer 9. The output shaft of 9 is connected to the rotating shaft, and the interior of the glass barrel 2 is divided into two separate spaces on the left and right by the arc spring metal sheet 3, so that the ore powder and the secondary resources can be placed in the two spaces respectively, and then through the double-axis motor 10, the double-axis motor 10 is externally connected to the power supply and the control switch, and the double-axis motor 10 can be driven by the upper worm gear reducer 8 and the lower worm gear reducer 9 at the same time, so that the lower worm gear reducer 9 drives the rotating shaft to rotate, and the rotating shaft drives the side plate 11 to rotate, so as to make the side plate 11 tilt to one side;

[0032] A bevel gear mechanism is installed between the rear part of the synchronous drive mechanism and the lower part of the vertical shaft rod 17. The upper worm and worm gear reducer 8 is fixed at the front end of the blanking frame 1. The upper output shaft of the double-shaft motor 10 is connected to the input shaft of the upper worm and worm gear reducer 8. The bevel gear mechanism includes a driven bevel gear 19, a horizontal shaft rod 20, and a driving bevel gear 21. The driven bevel gear 19 is fixed at the lower part of the vertical shaft rod 17. The driven bevel gear 19 is located below the baffle plate 16. The driving bevel gear 21 is meshed and connected to the front of the driven bevel gear 19. The horizontal shaft rod 20 is fixed at the front end of the driving bevel gear 21. The front end of the horizontal shaft rod 20 is connected to the output shaft of the upper worm and worm gear reducer 8. By means of the upper worm and worm gear reducer 8, the horizontal shaft rod 20 can be driven to rotate. The horizontal shaft rod 20 will drive the driving bevel gear 21 to rotate. As the driving bevel gear 21 meshes with the driven bevel gear 19, the driven bevel gear 19 will drive the vertical shaft rod 17 to rotate. In this way, the vertical shaft rod 17 can drive the baffle plate 16 to rotate until the baffle plate 16 rotates 180 degrees and then stops. In this way, the conveying assembly also tilts to a certain angle and then stops at the same time. When the conveying assembly tilts to the left, the bottom of the space on the left is opened, while the bottom of the space on the right is blocked by the baffle plate 16;

[0033] A pair of sub-pulling ropes 6 distributed front and back are fixed on both the left and right sides of the upper end of the conveying assembly. A main pulling rope 5 is connected between the ends of adjacent sub-pulling ropes 6. The end of the main pulling rope 5 penetrates into the glass material cylinder 2 and is fixed to the arc spring metal sheet 3. The tilting of the side plate 11 of the conveying assembly can pull the main pulling rope 5 through the sub-pulling ropes 6. Then the main pulling rope 5 pulls the arc spring metal sheet 3 to concave to the left. At this time, the space on the right increases, which is convenient for storing materials. The space on the left is squeezed by the arc spring metal sheet 3, playing a role in loosening the materials to prevent blockage. Finally, the materials in the space on the left fall onto the conveyor belt 13 and are supported by the support table 23. In this way, when the side plate 11 tilts to the left to make the conveyor belt 13 tilt to the left, the materials on the conveyor belt 13 can be tilted to the left to convey the materials above, and the feeding work is carried out by tilting to the left. When the conveying assembly is tilted to the right by means of the synchronous drive mechanism, the baffle plate 16 rotates 180 degrees to block the bottom of the space on the left. At the same time, the main pulling rope 5 on the right pulls the arc spring metal sheet 3 to concave to the right. At this time, the materials in the space on the right will fall onto the conveyor belt 13 and are supported by the support table 23. In this way, when the side plate 11 tilts to the right to make the conveyor belt 13 tilt to the right, the materials on the conveyor belt 13 can be tilted to the right to convey the materials above, and the feeding work is carried out by tilting to the right. The left and right ends of the conveying assembly are respectively located above the feeding structures of two smelting furnaces. In this way, one feeding device can be used for two smelting furnaces respectively, improving the practicability and facilitating the staff.

[0034] When the conveying component tilts towards one side, due to the center of gravity shifting towards one side, at this time the steel ball 28 will push the limit plate 27, and the limit plate 27 drives the synchronous belt 26 to move. In this way, the synchronous belt 26 drives the conveyor belt 13 to move. Thus, without power drive, the conveyor belt 13 actively moves to drive the ore powder or secondary resources for material conveying, playing an energy-saving role.

[0035] A transformer 4 is fixed at the rear end of the blanking frame 1. Generators 12 are fixedly installed on both the left and right sides of the rear part of the rear side plate 11. The rear part of the rotating shaft 24 penetrates through the side plate 11, and the rear part of the rotating shaft 24 is connected to the input shaft of the generator 12. The generator 12 is electrically connected to the transformer 4, and the transformer 4 is electrically connected to the arc-shaped electrochromic glass. When the synchronous belt 26 moves, the synchronous pulley 25 can also move. In this way, the movement of the synchronous pulley 25 drives the input shaft of the generator 12 to rotate through the rotating shaft 24. Thus, the kinetic energy is converted into electrical energy for power generation by the generator 12, and then the voltage is changed to a suitable voltage for the arc-shaped electrochromic glass through the transformer 4, so as to supply power to the arc-shaped electrochromic glass. Because when the arc-shaped electrochromic glass is powered off, the liquid crystal molecules inside the arc-shaped electrochromic glass will present an irregular dispersion state. At this time, the arc-shaped electrochromic glass presents a translucent and opaque appearance state. And when the arc-shaped electrochromic glass is powered on, the liquid crystal molecules inside are neatly arranged and the light can penetrate freely. At this time, the arc-shaped electrochromic glass instantly presents a transparent state. Therefore, when the conveyor belt 13 is moving, the current generated by the generator 12 is supplied to the arc-shaped electrochromic glass for use. In this way, it is convenient for the staff to judge how much material is left inside the glass cylinder 2 through the transparent arc-shaped electrochromic glass when adding materials. Moreover, the glass cylinder 2 has a high hardness and is not easily damaged. At the same time, it can improve the sense of technology during the use process, does not require additional power connection, and saves electrical energy.

[0036] A plurality of horn-shaped rubber covers 18 are fixedly sleeved on the outer part of the main pull rope 5 at equal intervals. Reserved holes are provided on the surfaces of the left and right arc-shaped electrochromic glass. An I-shaped sleeve 29 is fixed inside the reserved holes. The main pull rope 5 is inserted through the I-shaped sleeve 29. A plurality of fan-shaped rubber sheets 30 are fixedly arranged at equal intervals in a ring shape on the inner walls of the two openings of the I-shaped sleeve 29. The main pull rope 5 is located between the inner sides of the fan-shaped rubber sheets 30. The outer diameter of one end of the rubber cover 18 is larger than the inner diameter of the I-shaped sleeve 29, and the outer diameter of the other end of the rubber cover 18 is equal to the inner diameter of the I-shaped sleeve 29. When the main pull rope 5 is moving, it can move along the inside of the I-shaped sleeve 29. If the small-diameter end of the rubber cover 18 moves towards the I-shaped sleeve 29 at this time, the rubber cover 18 can be deformed and stuffed into the I-shaped sleeve 29, and at the same time, the fan-shaped rubber sheets 30 are pushed open until the large-diameter end enters the I-shaped sleeve 29 and has an interference fit with the I-shaped sleeve 29. When the large-diameter end of the rubber cover 18 moves towards the I-shaped sleeve 29, the large-diameter end of the rubber cover 18 will be first pushed open until the outer diameters of both ends of the rubber cover 18 are swapped, so as to facilitate driving the horn-shaped rubber cover 18 through the inside of the I-shaped sleeve 29. The cooperation between the horn-shaped rubber cover 18 and the fan-shaped rubber sheets 30 to fill the inside of the I-shaped sleeve 29 can not only improve the sealing performance between the main pull rope 5 and the glass cylinder 2, but also cause some jitters of the main pull rope 5 every time the rubber cover 18 moves out of the I-shaped sleeve 29, so as to play a role in vibrating the materials in the glass cylinder 2 to a certain extent.
