Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of solid metal material smelting, in particular to an energy-saving antimony smelting equipment and smelting process thereof. BACKGROUND

[0002] Solid metal smelting recovery is a process of recycling resources by remelting waste metal materials in a high-temperature furnace. The core is to convert solid metal into liquid state by high temperature, and remove oil stains, coatings and other non-metallic inclusions through methods such as slagging and refining, and adjust the alloy composition. This technology not only recycles valuable metals, but also reduces solid waste and primary ore mining, which is an important support for circular economy.

[0015] An energy-saving antimony smelting process, which is applicable to the energy-saving antimony smelting device and comprises the following steps: S1: First, the energy-saving antimony raw material is put into the inner cavity of the second feeding box, and the raw material is crushed by the crushing roller; S2: The air inlet pipe, circulation pipe and air outlet pipe circulate the air inside the heat preservation box through the first feed box, preheating the raw materials entering the first feed box. After the raw materials are preheated, they are driven to the furnace cavity by the auger driven by the third motor. S3: The fuel pipe introduces the propellant into the furnace cavity for combustion to smelt the raw materials; S4: The smelted raw materials are discharged through the discharge pipe and the receiving pipe.

[0016] The advantages of this invention are: 1. In this invention, the output shaft of a fourth motor drives a gear to rotate, and the two gears drive two crushing rollers to rotate respectively. The raw material is placed between the two crushing rollers. The two crushing rollers crush the raw material and then drive it into the inner cavity of the first feed box. The output shaft of a third motor drives an auger to rotate, and the raw material is slowly and orderly output into the inner cavity of the furnace through the feed pipe. Since the raw material is generally solid, it may stop at the edge of the first feed box. When the output shaft of the third motor rotates, it also drives the first pulley to rotate. Through belt drive, the second pulley also rotates. The second pulley drives the rotating block to rotate through the rotating shaft. The rotating block further drives the striking block to rotate. Several striking blocks will strike the outer wall of the first feed box, thereby causing the inner cavity of the first feed box to vibrate. This can make the raw material in the inner cavity of the first feed box fall to the bottom of the first feed box, and finally drive it into the inner cavity of the furnace through the auger.

[0017] 2. This invention uses a baffle to block the discharge pipe. When the baffle is inside the block, the raw material in the furnace cavity cannot pass through the discharge pipe. When it is necessary to discharge the raw material smelted in the furnace cavity, the baffle can be moved away from the block cavity. In use, first, the output end of the second electric telescopic rod is shortened. The output end of the second electric telescopic rod will slide along the inner cavity of the second groove with the first connecting ring and the pull rod. The pull rod will slide into the inner cavity of the first groove. Then, the output end of the third electric telescopic rod is contracted, which moves the second connecting ring and the pull rod upward, thereby pulling the baffle out of the block cavity. At this time, the raw material smelted in the furnace cavity will be discharged through the discharge pipe to the inner cavity of the receiving pipe.

[0018] 3. In this invention, the output shaft of the second motor drives the fan blades to rotate. The fan blades can draw hot air from the inner cavity of the heat preservation box into the inner cavity of the exhaust pipe. The hot air flows along the inner cavity of the exhaust pipe to the circulation pipe. The circulation pipe passes through the inner cavity of the first feed box and can preheat the raw materials in the inner cavity of the first feed box. The air that has been preheated will flow back to the inner cavity of the heat preservation box through the intake pipe. This avoids the waste of heat in the inner cavity of the heat preservation box. Preheating the raw materials also helps to increase the melting rate of the raw materials in the furnace cavity.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 7 As shown, an energy-saving antimony smelting equipment includes an insulated box 1, in which a furnace 24 is rotatably installed; it also includes a feeding mechanism for adding raw materials into the furnace 24; the feeding mechanism includes a first feeding box 4, which is fixedly installed on the top of the insulated box 1, and a feeding pipe 412 is fixedly connected to one side of the first feeding box 4. An auger 411 is rotatably installed in the inner cavity of the first feeding box 4, and a third motor 41 is fixedly connected to one end of the auger 411. Two first pulleys 42 are fixedly connected to the output shaft of the third motor 41. Two second pulleys 43 are rotatably installed on the top of the insulated box 1. The two first pulleys 42 are respectively driven by the two second pulleys 43 via belts 44. A rotating shaft 45 is fixedly connected to one side of the second pulleys 43. Two rotating blocks 46 are fixedly connected to the outer surface of the rotating shaft 45. A striking block 47 is rotatably connected to the outer surface of the rotating blocks 46. Two crushing rollers 53 are rotatably installed on the top of the first feeding box 4. A second feed box 5 is fixedly installed on the top of the first feed box 4. Both of the crushing rollers 53 are rotatably installed in the inner cavity of the second feed box 5. Two meshing gears 51 are rotatably installed on one side of the second feed box 5. A fourth motor 52 is fixedly connected to one side of one of the gears 51. The fourth motor 52 is fixedly installed on one side of the second feed box 5.

[0024] Existing antimony smelting equipment involves directly adding raw materials into the furnace during operation. For large volumes of raw materials, the smelting time is very long and more fuel is required.

[0025] In use, the raw material is first added to the inner cavity of the second feed box 5. The output shaft of the fourth motor 52 drives the gear 51 to rotate, and the two gears 51 drive the two crushing rollers 53 to rotate respectively. The raw material is placed between the two crushing rollers 53. After the two crushing rollers 53 crush the raw material, it is driven to the inner cavity of the first feed box 4. The output shaft of the third motor 41 drives the auger 411 to rotate, and the raw material is slowly and orderly output to the inner cavity of the furnace 24 through the feed pipe 412. Since the raw material is generally solid, the raw material may stop in the first feed box 4. At the edge of the feed box 4, when the output shaft of the third motor 41 rotates, it will also drive the first pulley 42 to rotate. Through the belt 44, the second pulley 43 will also rotate. The second pulley 43 drives the rotating block 46 to rotate through the rotating shaft 45. The rotating block 46 further drives the striking block 47 to rotate. Several striking blocks 47 will strike the outer wall of the first feed box 4, thereby causing the inner cavity of the first feed box 4 to vibrate. This action can make the raw material in the inner cavity of the first feed box 4 fall to the bottom of the first feed box 4, and finally drive it to the inner cavity of the furnace 24 through the auger 411.

[0026] Furthermore, such as Figure 2 As shown, two connecting columns 25 are rotatably installed inside the heat preservation box 1. Both connecting columns 25 are fixedly connected to the furnace 24. A connecting rod 23 is rotatably connected to the bottom of the furnace 24. A sliding rod 2 is rotatably connected to one side of the connecting rod 23. The sliding rod 2 is slidably connected to the heat preservation box 1. A reciprocating screw 21 is threadedly connected to one side of the slide rod 2. The reciprocating screw 21 is rotatably installed on one side of the heat preservation box 1. A first motor 22 is fixedly connected to one end of the reciprocating screw 21. The first motor 22 is fixedly installed on one side of the heat preservation box 1. A fuel pipe 26 is fixedly installed inside the heat preservation box 1.

[0027] In use, to further increase the melting speed of raw materials in the inner cavity of the furnace 24, the output shaft of the first motor 22 drives the reciprocating screw 21 to rotate. The reciprocating screw 21 further drives the slide bar 2 to slide back and forth. When the slide bar 2 slides, it will drive the connecting rod 23 to rotate together. The connecting rod 23 further pulls the furnace 24 to rotate. This allows the raw materials in the inner cavity of the furnace 24 to shake. The movement of the raw materials in the inner cavity of the furnace 24 can avoid continuously heating a certain part of the raw materials. By uniformly heating the raw materials in the inner cavity of the furnace 24, the purpose of increasing the heating rate and saving energy is achieved. The shaking amplitude of the furnace 24 pulled by the connecting rod 23 is small, so there is no need to worry about raw materials shaking out of the furnace 24.

[0028] Furthermore, such as Figure 3 and Figure 4 As shown, a discharge pipe 27 is fixedly connected to the outer surface of the furnace 24, a block 271 is fixedly connected to one side of the discharge pipe 27, a stop block 272 is slidably installed in the inner cavity of the block block 271, and a first groove 2721 is provided on one side of the stop block 272; A pull rod 2722 is slidably installed in the inner cavity of the first groove 2721. A second groove 273 is provided on the top of the insulated box 1. The pull rod 2722 is slidably installed in the inner cavity of the second groove 273. A third groove 2723 is provided on the outer surface of the pull rod 2722. An operation box 274 is fixedly installed on the top of the insulation box 1. A first connecting ring 2741 is slidably installed on the outer surface of the pull rod 2722. A second electric telescopic rod 2742 is fixedly connected to one side of the first connecting ring 2741. The second electric telescopic rod 2742 is fixedly connected to the operation box 274. A second connecting ring 275 is slidably installed in the inner cavity of the third groove 2723. A third electric telescopic rod 2751 is fixedly connected to one side of the second connecting ring 275. The third electric telescopic rod 2751 is fixedly connected to the operation box 274.

[0029] In use, to prevent molten material from flowing out of the furnace 24 during heating, the present invention uses a baffle 272 to block the discharge pipe 27. When the baffle 272 is inside the block 271, the material inside the furnace 24 cannot pass through the discharge pipe 27. When it is necessary to discharge the molten material from the furnace 24, the baffle 272 is moved away from the block 271. In use, the output end of the second electric telescopic rod 2742 is first shortened, and the second electric... The output end of the telescopic rod 2742 will slide along the inner cavity of the second groove 273 with the first connecting ring 2741 and the pull rod 2722. The pull rod 2722 will slide into the inner cavity of the first groove 2721. Then, the output end of the third electric telescopic rod 2751 will retract, moving the second connecting ring 275 and the pull rod 2722 upward, thereby pulling the stop block 272 out of the inner cavity of the block block 271. At this time, the raw materials for smelting in the inner cavity of the furnace 24 will be discharged through the discharge pipe 27 to the inner cavity of the receiving pipe 28.

[0030] Furthermore, such as Figure 2 As shown, a receiving pipe 28 is fixedly installed in the inner cavity of the heat preservation box 1, and a first electric telescopic rod 282 is fixedly installed on one side of the heat preservation box 1. A baffle 281 is fixedly connected to the output end of the first electric telescopic rod 282, and the baffle 281 is slidably installed in the inner cavity of the receiving pipe 28.

[0031] When in use, the first electric telescopic rod 282 retracts at its output end, and moves the baffle 281 upwards, allowing the molten raw material to be discharged from the inner cavity of the receiving pipe 28. When molten raw material, the baffle 281 blocks the receiving pipe 28, preventing heat loss from the inner cavity of the insulation box 1.

[0032] Furthermore, such as Figure 5As shown, an air inlet pipe 3 and an air outlet pipe 32 are fixedly installed on the outer surface of the heat preservation box 1. The air inlet pipe 3 and the air outlet pipe 32 are in communication with the inner cavity of the heat preservation box 1. A plurality of circulation pipes 31 are fixedly connected between the air inlet pipe 3 and the air outlet pipe 32. The plurality of circulation pipes 31 pass through the inner cavity of the first feed box 4. A fan blade 33 is rotatably installed in the inner cavity of the air outlet pipe 32. A second motor 34 is fixedly connected to one side of the fan blade 33. The second motor 34 is fixedly installed on one side of the heat preservation box 1.

[0033] In use, the second motor 34 drives the fan blades 33 to rotate via its output shaft. The fan blades 33 draw hot air from the inner cavity of the insulation box 1 into the inner cavity of the exhaust pipe 32. The hot air flows along the inner cavity of the exhaust pipe 32 to the circulation pipe 31. The circulation pipe 31 passes through the inner cavity of the first feed box 4 and can preheat the raw materials in the inner cavity of the first feed box 4. The air that has been preheated will flow back to the inner cavity of the insulation box 1 through the intake pipe 3. This avoids the waste of heat in the inner cavity of the insulation box 1. Preheating the raw materials also helps to increase the melting rate of the raw materials in the inner cavity of the furnace 24.

[0034] An energy-saving antimony smelting process is provided, applicable to the aforementioned energy-saving antimony smelting equipment. The smelting process includes the following steps: S1: First, the energy-saving antimony raw material is fed into the inner cavity of the second feed box 5, and the raw material is crushed by the crushing roller 53. S2: The air inlet pipe 3, the circulation pipe 31 and the air outlet pipe 32 cause the air inside the heat preservation box 1 to circulate through the inside of the first feed box 4, preheating the raw materials entering the inside of the first feed box 4. After the raw materials are preheated, they are driven to the inside of the furnace 24 by the auger 411 driven by the third motor 41. S3: Fuel pipe 26 introduces the propellant into the inner cavity of furnace 24 for combustion to smelt the raw materials; S4: The smelted raw materials are discharged through the discharge pipe 27 and the receiving pipe 28.

[0035] Working principle: The output shaft of the fourth motor 52 drives the gear 51 to rotate. The two gears 51 drive the two crushing rollers 53 to rotate respectively. The raw material is between the two crushing rollers 53. The two crushing rollers 53 crush the raw material and then drive the raw material into the inner cavity of the first feed box 4. The output shaft of the third motor 41 drives the auger 411 to rotate and slowly and orderly output the raw material through the feed pipe 412 into the inner cavity of the furnace 24. Since the raw material is generally solid, it may stop at the edge of the first feed box 4. When the output shaft of the third motor 41 rotates, it also drives the first pulley 42 to rotate. Through the belt 44, the second pulley 43 will also rotate. The second pulley 43 drives the rotating block 46 to rotate through the rotating shaft 45. The rotating block 46 further drives the striking block 47 to rotate. Several striking blocks 47 will strike the outer wall of the first feed box 4, thereby causing the inner cavity of the first feed box 4 to vibrate. This can make the raw material in the inner cavity of the first feed box 4 fall to the bottom of the first feed box 4. Finally, it is driven into the inner cavity of the furnace 24 by the auger 411.

[0036] By blocking the discharge pipe 27 with the stop block 272, when the stop block 272 is inside the block 271, the raw material inside the furnace 24 cannot pass through the discharge pipe 27. When it is necessary to discharge the raw material smelted inside the furnace 24, the stop block 272 is moved away from the block 271. In use, first, the output end of the second electric telescopic rod 2742 is shortened. The output end of the second electric telescopic rod 2742 will slide along the inner cavity of the second groove 273 with the first connecting ring 2741 and the pull rod 2722. The pull rod 2722 will slide into the inner cavity of the first groove 2721. Then, the output end of the third electric telescopic rod 2751 is retracted, which moves the second connecting ring 275 and the pull rod 2722 upward, thereby allowing... When the baffle 272 is pulled out from the inner cavity of the block 271, the raw material to be smelted in the inner cavity of the furnace 24 will be discharged through the discharge pipe 27 to the inner cavity of the receiving pipe 28. The output shaft of the second motor 34 drives the fan blade 33 to rotate. The fan blade 33 can draw the hot air in the inner cavity of the heat preservation box 1 into the inner cavity of the air outlet pipe 32. The hot air flows along the inner cavity of the air outlet pipe 32 to the circulation pipe 31. The circulation pipe 31 passes through the inner cavity of the first feed box 4 and can preheat the raw material in the inner cavity of the first feed box 4. The air after preheating the raw material will flow back to the inner cavity of the heat preservation box 1 through the air inlet pipe 3. This avoids the waste of heat in the inner cavity of the heat preservation box 1. Preheating the raw material is also conducive to increasing the melting rate of the raw material in the inner cavity of the furnace 24.
