[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0029] According to the embodiments of the present utility model, Figure 1 and Figure 2 As shown, a smelting furnace charging structure is provided, including: a charging barrel 1, a movable plate assembly 2, a hanging member 3 and a linkage assembly 4. The charging barrel 1 has a charging cavity, and the two ends of the charging barrel 1 respectively form a feed port 101 and a discharge port 102, and the feed port 101 and the discharge port 102 are both connected to the charging cavity. The movable plate assembly 2 is hinged to the charging barrel 1 and is arranged corresponding to the discharge port 102. The movable plate assembly 2 has an open position and a closed position. In the open position, the movable plate assembly 2 rotates away from the discharge port 102, and in the closed position, the movable plate assembly 2 blocks the discharge port 102. The hanging member 3 is sleeved on the outer wall surface of the charging barrel 1. One end of the linkage assembly 4 is connected to the hanging member 3, and the other end of the linkage assembly 4 is rotatably connected to the movable plate assembly 2. The hanging member 3 and the linkage assembly 4 can be moved up and down along the outer wall surface of the charging barrel 1 to switch the movable plate assembly 2 between the open position and the closed position.

[0030] The movable plate assembly 2 is controlled to switch between the open position and the closed position by the up and down movement of the hoisting member 3 and the linkage assembly 4, so that the charging and unloading of the charging barrel 1 can be realized during the hoisting process. There is no need to manually carry the charging barrel 1 to add materials and then put it into the smelting furnace, which optimizes the transportation process, avoids the waste of time in secondary transportation, further reduces the production auxiliary processes, and improves production efficiency.

[0031] Specifically, a lifting hole is provided on the lifting member 3 for connecting with a lifting device, and the smelting furnace charging structure is lifted by the lifting device.

[0032] Specifically, in this embodiment, the feeding barrel 1 is a cylinder with a feeding cavity, the upper end of the feeding barrel 1 forms a feeding port 101, the lower end of the feeding barrel 1 forms a discharging port 102, and the movable plate assembly 2 is used to open or close the discharging port 102.

[0033] In one embodiment, Figure 2 As shown, the movable plate assembly 2 includes a first movable plate 201 and a second movable plate 202. The two sides of the first movable plate 201 and the second movable plate 202 that are far from each other are respectively hingedly arranged with the opposite two sides of the charging barrel 1. In the closed position, the two sides of the first movable plate 201 and the second movable plate 202 that are close to each other are abutted and spliced. In the open position, the two sides of the first movable plate 201 and the second movable plate 202 that are close to each other are arranged far away. By hingedly arranging the first movable plate 201 and the second movable plate 202 with the charging barrel 1, the conversion of the first movable plate 201 and the second movable plate 202 between the open position and the closed position is more convenient.

[0034] Specifically, in this embodiment, the first movable plate 201 and the second movable plate 202 are arranged corresponding to the bottom shape of the feeding barrel 1, and the area of ​​the first movable plate 201 and the second movable plate 202 is not less than 1 / 2 of the bottom area of ​​the feeding barrel 1 (that is, the area of ​​the discharge port 102), so that the first movable plate 201 and the second movable plate 202 can completely close the bottom surface of the feeding barrel 1.

[0035] In one embodiment, Figure 1 and Figure 2 As shown, the linkage assembly 4 includes a lifting rod 401 and a linkage rod 402. The upper end of the lifting rod 401 is connected to the lifting component 3, the lower end of the lifting rod 401 is connected to the first ends of the two linkage rods 402, and the second ends of the two linkage rods 402 are rotatably connected to the first movable plate 201 and the second movable plate 202 respectively.

[0036] Specifically, in this embodiment, two lifting rods 401 are provided, and the two lifting rods 401 are provided on opposite sides of the feeding barrel 1, that is, along the circumference of the feeding barrel 1, the two lifting rods 401 are provided at an interval of 180°. The upper end of each lifting rod 401 is connected to the hanging member 3, and the lower end of each lifting rod 401 is connected to two linkage rods 402. By providing two lifting rods 401 and allowing each lifting rod 401 to be provided with two linkage rods 402, the force on the first movable plate 201 and the second movable plate 202 is made more uniform, the opening and closing of the first movable plate 201 and the second movable plate 202 are made more stable, and a large deviation is avoided during the rotation process of the first movable plate 201 and the second movable plate 202, thereby improving the service life of the first movable plate 201 and the second movable plate 202.

[0037] It is worth noting that the feeding bucket 1 is hoisted by the hoisting member 3. The upward lifting force of the hoisting member 3 and the linkage assembly 4 overcomes the deadweight of the feeding bucket 1. Without providing additional force, the first movable plate 201 and the second movable plate 202 can be closed to form a container with a closed bottom. When materials are added, the more materials are added, the heavier the feeding bucket 1 is, the greater the upward force on the first movable plate 201 and the second movable plate 202 is, and the tighter the closure is, thereby preventing the feeding bucket 1 from leaking.

[0038] It should be further explained that, during the process of unloading into the smelting furnace, after the feeding bucket 1 is placed at the predetermined feeding position of the smelting furnace, the lifting component 3 is in a free state, and under the action of the material's own weight, the first movable plate 201 and the second movable plate 202 are opened to complete the unloading, and the first movable plate 201 and the second movable plate 202 can be fully opened, thereby achieving complete unloading, and the feeding bucket 1 is not easy to accumulate material.

[0039] In one embodiment, Figure 1 and Figure 2 As shown, the charging structure of the smelting furnace further includes a lifting rod guide 5, which is enclosed with the outer wall of the charging barrel 1 to form a limiting space, and the lifting rod 401 is inserted into the limiting space. A plurality of lifting rod guides 5 are arranged at intervals along the extending direction of the lifting rod 401. By using the lifting rod guide 5 to limit and guide the lifting rod 401, it is avoided that the lifting rod 401 and the linkage rod 402 connected to the lifting rod 401 are broken or damaged due to a large position deviation of the lifting rod 401 during the movement, thereby improving the service life of the lifting rod 401 and the linkage rod 402.

[0040] In one embodiment, Figure 1 and Figure 2 As shown, the charging structure of the smelting furnace further includes a support member 6, and a plurality of support members 6 are arranged along the outer wall of the charging barrel 1. In the open position, the support member 6 is suitable for abutting against the inner wall of the smelting furnace. The support member 6 is arranged to support the charging barrel 1 after the charging barrel 1 reaches the predetermined charging position in the smelting furnace, so as to prevent the charging barrel 1 from extending too deeply into the smelting furnace, thereby causing damage to the charging barrel 1.

[0041] In one embodiment, Figure 1 and Figure 2 As shown, the smelting furnace charging structure also includes a guide assembly 7, and a plurality of guide assemblies 7 are arranged at intervals on the outer wall surface of the charging barrel 1. The setting of the guide assembly 7 makes it more accurate when the charging barrel 1 is hoisted above the smelting furnace and enters the smelting furnace. At the same time, the setting of the guide assembly 7 avoids a large shaking of the charging barrel 1 during the charging process, thereby improving the safety of the hoisting of the charging barrel 1.

[0042] In one embodiment, Figure 1 and Figure 2As shown, the guide assembly 7 includes a first guide plate 701, which extends upward from the bottom of the outer wall of the feeding barrel 1, and the extended end of the first guide plate 701 is close to the top of the outer wall of the feeding barrel 1. A plurality of first guide plates 701 are arranged at circumferential intervals along the outer wall of the feeding barrel 1.

[0043] In one embodiment, Figure 1 and Figure 2 As shown, the guide assembly 7 also includes a second guide plate 702, which extends upward from the bottom of the outer wall of the feeding barrel 1, and the extended end of the second guide plate 702 is close to the middle of the outer wall of the feeding barrel 1. A plurality of second guide plates 702 are arranged at circumferential intervals along the outer wall of the feeding barrel 1.

[0044] In one embodiment, Figure 1 and Figure 2 As shown, the guide assembly 7 also includes a third guide plate 703, which is arranged at the bottom of the outer wall of the feeding barrel 1, and the extended end of the third guide plate 703 is located at the lower side of the second guide plate 702. A plurality of third guide plates 703 are arranged at circumferential intervals along the outer wall of the feeding barrel 1.

[0045] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, two first guide plates 701 are provided, and the two first guide plates 701 are arranged on opposite sides of the feeding barrel 1, that is, along the circumference of the feeding barrel 1, the two first guide plates 701 are arranged at an interval of 180°. Two groups of second guide plates 702 are provided, and each group of second guide plates 702 is provided with two, and the two second guide plates 702 are arranged on opposite sides of the feeding barrel 1, that is, along the circumference of the feeding barrel 1, the two second guide plates 702 are arranged at an interval of 180°, and another group of second guide plates 702 are also arranged at an interval of 180°. Two third guide plates 703 are provided, and the two third guide plates 703 are arranged on opposite sides of the feeding barrel 1, that is, along the circumference of the feeding barrel 1, the two first guide plates 701 are arranged at an interval of 180°. With this arrangement, the positioning of the feeding barrel 1 when it is hoisted and inserted into the smelting furnace is more accurate.

[0046] In one embodiment, Figure 3 and Figure 4 As shown, the hanging member 3 is simultaneously sleeved on the outer periphery of the feeding bucket 1 and the first guide plate 701. The hanging member 3 is sleeved on the outer periphery of the feeding bucket 1 and the first guide plate 701 so that the hanging member 3 will not interfere with or collide with the feeding bucket 1 and the first guide plate 701 when moving, thereby completing the feeding work of the feeding bucket 1 more conveniently.

[0047] Preferably, the hanging member 3 is a ring-shaped body with a square outer contour, and the first guide plate 701 is located in the diagonal direction of the hanging member 3 by utilizing the principle that the diagonal distance of a square is longer, which is beneficial to reducing the size of the feeding barrel 1 as a whole.

[0048] In an alternative embodiment, the structure of the feeding barrel 1 may not be a cylinder, but an arbitrary cube with a feeding cavity, and the first movable plate 201 and the second movable plate 202 are changed corresponding to the bottom shape of the feeding barrel 1 to achieve a sealing effect.

[0049] It is worth noting that the embodiment of the utility model can add materials to the feeding bucket 1 during the lifting process, and can also unload materials into the smelting furnace without detaching the lifting component 3. The overall structure is simple, convenient and fast, with high work efficiency, avoiding the additional workload of carrying the feeding bucket 1 during the charging and unloading process.

[0050] It should be further explained that the loading and unloading processes can be automated and unmanned, thereby reducing the safety risks to humans during the lifting process.

[0051] When using the smelting furnace charging structure of the present embodiment, first, the smelting furnace charging structure is lifted to the top of the smelting furnace by using the lifting component 3; then, materials are added into the charging barrel 1; then, the charging barrel 1 is placed into the smelting furnace until the support component 6 stops descending after being forced into contact with the inner wall of the smelting furnace; finally, the lifting component 3 is released, and under the influence of the dead weight of the materials in the charging barrel 1, the first movable plate 201 and the second movable plate 202 are opened to both sides, and the materials can easily fall into the smelting furnace.

[0052] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
