[0030] This utility model provides a quantitative feeding structure for a smelting furnace.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 as well as Figure 9The furnace includes a furnace body 1, with a guide hopper 11 fixedly connected to the top of the furnace body 1. A feeding component is provided above the guide hopper 11, and a sealing component is provided inside the guide hopper 11. The feeding component includes vertical plates 21 fixedly connected to both sides of the top of the furnace body 1, a rotating shaft 22 connected to the vertical plates 21, a support base 23 fixedly connected to the outside of the rotating shaft 22, a weighing scale 24 fixedly connected to the top of the support base 23, a worm gear 25 fixedly connected to the outside of the rotating shaft 22, a worm 26 connected to the worm gear 25, a first motor 27 fixedly connected to one end of the worm 26, and a shielding part for preventing raw material splashing. The worm gear 25 meshes with the worm 26, and the rotating shaft 22 is rotatably connected to the vertical plate 21. Raw materials can be accurately measured using the weighing scale 24. The first motor 27 controls the rotation of the worm 26, which in turn controls the rotation of the worm gear 25, thereby driving the rotating shaft 22 to rotate. The rotating shaft 22 drives the support base 23 and the weighing scale 24 to rotate, facilitating the pouring of raw materials from the top of the weighing scale 24 into the guide hopper 11, achieving precise quantitative feeding. The shielding component includes a shielding frame 41 fixedly connected to the top of the support base 23, a fixed shaft 42 connected to the shielding frame 41, and a fixed shaft... A third motor 43 is fixedly connected to one end of the fixed shaft 42, and a baffle 44 is fixedly connected to the outside of the fixed shaft 42. The fixed shaft 42 is rotatably connected to the baffle frame 41. The baffle frame 41 and the baffle 44 can surround the weighing scale 24 to prevent falling raw materials from splashing out and can block the raw materials. The third motor 43 can drive the fixed shaft 42 to rotate, thereby controlling the rotation of the baffle 44, which can facilitate the discharge of raw materials on the weighing scale 24. A support groove 51 is opened on one side of the vertical plate 21, and support blocks 52 are slidably connected to both sides of the support groove 51. The rotating shaft 22 is fixed on both sides. A fixed disk 53 is connected to the support block 52, which is fixedly connected to the fixed disk 53. The rotating shaft 22 can drive the fixed disk 53 to rotate synchronously, which in turn can drive the support block 52 to rotate synchronously. The support block 52 can support the rotation of the rotating shaft 22, improve the rotation stability of the rotating shaft 22, and prevent it from tilting. Support rods 61 are fixedly connected to the top two sides of the furnace body 1, and a storage hopper 62 is fixedly connected between the two support rods 61. A solenoid valve 63 is installed at the bottom of the storage hopper 62. Raw materials can be stored in the storage hopper 62. The opening and closing of the solenoid valve 63 can control whether the raw materials are discharged.

[0032] In use, the solenoid valve 63 opens, allowing the raw material in the storage hopper 62 to fall onto the top of the weighing scale 24. When the required value is reached, the solenoid valve 63 closes, and the first motor 27 and the third motor 43 start. The first motor 27 controls the worm gear 26 to rotate, which in turn controls the worm wheel 25 to rotate, thereby driving the rotating shaft 22 and the support seat 23 to rotate, which in turn drives the weighing scale 24 to rotate. The third motor 43 drives the baffle 44 to rotate. At this time, the raw material enters the guide hopper 11 under the action of gravity, and then enters the furnace body 1 for melting, realizing precise quantitative feeding.

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 5 as well as Figure 6 The enclosing component includes movable openings 31 respectively opened on both sides of the upper part of the guide hopper 11, a sealing plate 32 disposed in the movable openings 31, sliding grooves 33 opened on both sides of the front of the movable openings 31, a slider 34 disposed in the sliding grooves 33, a bidirectional screw 35 connected to the slider 34, and a second motor 36 fixedly connected to one end of the bidirectional screw 35. The bidirectional screw 35 is screwed to the slider 34 and rotatably connected to the guide hopper 11. The slider 34 is slidably connected to the sliding grooves 33 and fixedly connected to the sealing plate 32. The slider 34 and the sliding grooves 33 are both T-shaped. The second motor 36 can control the rotation of the bidirectional screw 35 when started. The bidirectional screw 35 can drive the two sliders 34 to move in opposite directions, thereby controlling the two sealing plates. The plate 32 can be attached to or away from the furnace body 1. When attached, it can seal the furnace body 1 and reduce heat loss. When separated, it can facilitate material feeding. Two guide grooves 71 are opened on the side of the moving port 31 away from the slide groove 33. A guide block 72 is slidably connected in the guide groove 71. The guide block 72 is fixedly connected to the sealing plate 32. The guide block 72 and the guide groove 71 are both T-shaped. The guide block 72 can move synchronously with the sealing plate 32. The guide block 72 can guide the sealing plate 32 and improve the stability of the sealing plate 32. Fixed legs 81 are fixedly connected to the bottom of the furnace body 1 around the perimeter. Anti-slip seats 82 are fixedly connected to the bottom of the fixed legs 81. The fixed legs 81 and anti-slip seats 82 can stably support the furnace body 1 and prevent the furnace body 1 from tipping over.

[0034] When this utility model is in use: the second motor 36 can start to control the rotation of the bidirectional screw 35. The rotation of the bidirectional screw 35 can control the two sliders 34 to move in opposite directions, which in turn can drive the two sealing plates 32 to move. The two sealing plates 32 can be merged or separated. When merged, the guide hopper 11 can be sealed to reduce heat loss. When separated, the top of the guide hopper 11 can be opened to facilitate the raw material to pass through the guide hopper 11 and enter the furnace body 1.

[0035] Working principle: During operation, raw materials are stored in the storage hopper 62. When feeding is required, the solenoid valve 63 opens, discharging the raw materials from the storage hopper 62 onto the top of the weighing scale 24. The weighing scale 24 accurately measures the raw materials. When the measured value is reached, the solenoid valve 63 closes, preventing further discharge. Then, the second motor 36 starts, driving the bidirectional screw 35 to rotate. The rotation of the bidirectional screw 35 moves the two sliders 34 to the sides, which in turn move the closing plates 32. The two closing plates 32 then separate, opening the top of the guide hopper 11. The first motor 27 and the third motor 43 then start. Motor 27 drives worm 26 to rotate, worm 26 drives worm wheel 25 to rotate, worm wheel 25 drives shaft 22 to rotate, shaft 22 drives support 23 to rotate, support 23 drives weighing scale 24 to rotate, and third motor 43 drives fixed shaft 42 to rotate, fixed shaft 42 drives baffle 44 to rotate. As weighing scale 24 rotates, raw materials fall into guide hopper 11 under gravity and are then discharged into furnace 1 for smelting. The first motor 27, second motor 36 and third motor 43 reverse, causing weighing scale 24, closed plate 32 and baffle 44 to reset, facilitating subsequent material supply.
