[0001] This utility model relates to the field of smelting equipment technology, specifically to a feeding device for an industrial furnace. Background Technology

[0002] Traditional industrial furnace charging process is a single-span station, which can only move within the smelting span at a time. The following steps must be completed before charging can be carried out. First, the prepared raw materials are hoisted onto the transfer car in the batching area. Then, the transfer car is driven to the smelting area, and the raw materials are hoisted by the crane in the smelting area. The raw materials are unloaded into the storage area to wait for charging arrangements. After the furnace order is arranged, the raw materials are hoisted into the charging car and then sent into the furnace by the charging car.

[0003] However, the above-mentioned feeding steps involve a large number of hoisting operations, which will lengthen the feeding time, increase the labor intensity of workers, and thus reduce the feeding efficiency.

[0004] In summary, existing industrial furnaces suffer from low feeding efficiency. Utility Model Content

[0025] Specific implementation method one: Combining Figures 1 to 3 This embodiment describes a method comprising a transfer car 1, a conveyor car 2, and a feeding car 3. The transfer car 1 is located within the raw material area 4, where raw materials are placed at the batching position. When the transfer car 1 moves to the batching position, it lifts the raw materials from the batching position into the feeding car 3. The transfer car 1 is adapted to move the feeding car 3 between the transfer limit 5 and the batching position. The conveyor car 2 is located within the smelting area 6 and is adapted to move the feeding car 3 between the transfer limit 5 and the smelting furnace. The feeding car 3 is moved and has a hopper 7 for placing raw materials. The feeding car 3 is placed on the crossover car 1 or the transfer car 2. When the crossover car 1 and the transfer car 2 move to the crossover limit 5 and dock with each other, the feeding car 3 moves from one of the crossover car 1 and the transfer car 2 to the other. When smelting, the feeding car 3 is placed on the crossover car 1 and moves from the crossover car 1 to the transfer car 2. When loading, the feeding car 3 is placed on the transfer car 2 and moves from the transfer car 2 to the crossover car 1.

[0026] It should be noted that the cross-pass vehicle 1 moves along the first direction, and the transfer vehicle 2 moves along the second direction. The first and second directions are perpendicular. The cross-pass limit 5 is the end point of the cross-pass vehicle 1 and the starting point of the transfer vehicle 2. The cross-pass vehicle 1 and the transfer vehicle 2 can dock with each other at the cross-pass limit 5. Figures 1 to 3 Both the intermediate cross-pass vehicle 1 and the transfer vehicle 2 are integral structures after the feeding vehicle 3 is installed.

[0027] In this embodiment of the feeding device for an industrial furnace, during feeding, the feeder 3 is first moved to the raw material area 4 by the cross-pass 1, and the raw material prepared in the raw material area 4 is hoisted into the feeder 3. Then, the cross-pass 1 and the transfer 2 are moved to the cross-pass limit 5 and docked. The feeder 3 moves autonomously from the cross-pass 1 to the transfer 2, and then the transfer 2 moves the feeder 3 to the smelting furnace, where the raw material is added into the smelting furnace at once. The entire transportation process only requires one hoisting, reducing the number of hoisting operations, greatly saving feeding time and reducing the labor intensity of workers.

[0028] Specific Implementation Method Two: Combining Figures 1 to 3 This embodiment differs from Specific Embodiment 1 in that both the transfer vehicle 1 and the transport vehicle 2 are equipped with guide structures 8 for cooperating with the feeding vehicle 3. The guide structures 8 allow the feeding vehicle 3 to move along a fixed path, resulting in better stability and ensuring stable material delivery. Of course, the above description is not limiting. As an alternative embodiment, the guide structures 8 can be omitted, and the movement path of the feeding vehicle 3 can be manually controlled. Other components and connections are the same as in Specific Embodiment 1.

[0029] Specific implementation method three: Combining Figures 1 to 3This embodiment differs from Specific Embodiment Two in that the guide structure 8 includes multiple parallel and spaced guide rails. The guide rail distribution is the same on the crossing vehicle 1 and the transfer vehicle 2. The wheels of the feeding vehicle 3 are rolled on the guide rails. When the crossing vehicle 1 and the transfer vehicle 2 are connected at the crossing limit 5, the guide rails are also connected. The feeding vehicle 3 moves along the guide rails from the crossing vehicle 1 to the transfer vehicle 2 or from the transfer vehicle 2 to the crossing vehicle 1, thus guiding the feeding vehicle 3. Of course, the above description is not limiting. As an alternative embodiment, the guide structure 8 may also include multiple parallel and spaced grooves, in which the wheels of the feeding vehicle 3 are rolled. Other components and connections are the same as in Specific Embodiment Two.

[0030] Specific implementation method four: Combination Figures 1 to 3 This embodiment differs from specific embodiment one in that the hopper 7 has an inverted trapezoidal structure, and the opening of the hopper 7 gradually decreases in size from top to bottom. Due to its inverted trapezoidal shape, the hopper 7 is more convenient to pour raw materials, allowing for more efficient material discharge and preventing material accumulation and residue. Of course, the above description is not limiting; as an alternative embodiment, the hopper 7 can also have a rectangular structure. Other components and connections are the same as in specific embodiment three.

[0031] Specific Implementation Method Five: Combining Figure 1 , Figure 3 This embodiment differs from Specific Embodiment 1 in that a support member 9 is connected to the overpass 1 to support the bottom of the feeding trolley 3. After the feeding trolley 3 moves onto the overpass 1, the support member 9 is activated, supporting the bottom of the feeding trolley 3 and thus reducing the pressure on the wheels. Other components and connections are the same as in Specific Embodiment 1.

[0032] Specific Implementation Method Six: Combination Figure 1 , Figure 3 This embodiment differs from specific embodiment five in that the support member 9 consists of several sets of hydraulic cylinders. These cylinders exert greater thrust, providing better support for the feeding vehicle 3 and making it easier to lift off the ground. Of course, the above description is not limiting. As an alternative embodiment, the support member 9 can also be several sets of pneumatic cylinders or an electric telescopic rod. Other components and connections are the same as in specific embodiment five.

The counterweight 10 and the raw material in the hopper 7 are mutually balanced, resulting in more even force distribution on the feeding cart 3, preventing tipping, reducing safety hazards, and ensuring feeding efficiency. Furthermore, placing the hopper 7 at the front end makes unloading more convenient. Other components and connections are the same as in Specific Embodiment 1.

[0034] Specific implementation method eight: Combination Figures 1 to 3 This embodiment differs from specific embodiment seven in that the counterweight 10 is an anti-tilting track. The track moves together with the feeding trolley 3, increasing the support area of ​​the feeding trolley 3, thus providing both balance and stability. Of course, the above description is not limiting; as an alternative embodiment, the counterweight 10 can also be a rectangular block. Other components and connections are the same as in specific embodiment seven.

[0035] Specific Implementation Method Nine: Combining Figures 1 to 3 This embodiment differs from specific embodiment one in that the feeding cart 3 has a drive device for pushing the hopper 7 to unload material. The drive device is hydraulically driven, which provides greater driving force, allowing for easier unloading of the hopper 7 when it is full of raw materials. Of course, the above description is not limiting; as an alternative embodiment, the drive device can also be pneumatically driven or electrically driven. Other components and connections are the same as in any of specific embodiments one through eight.

[0036] The working principle of this implementation method is as follows:

[0037] During loading, the feeding car 3 is first moved onto the crossover car 1. The crossover car 1 then moves the feeding car 3 to the batching position, where the raw materials are hoisted into the feeding car 3. At the same time, the crossover car 1 and the transfer car 2 are started, so that they move to the crossover limit 5 and dock with each other. Then the feeding car 3 is started, and it moves from the crossover car 1 onto the transfer car 2. The transfer car 2 then moves the feeding car 3 to the smelting furnace for unloading.
