Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to a furnace front bulk material feeding device. Background Technology

[0002] Industrial aluminum smelting requires adding materials into the smelting furnace during the smelting process. If small-volume bulk materials are added during the feeding process, the large transportation volume may cause materials to fall along the way, which can easily cause dirt and mess in front of the furnace and affect the accuracy of the feeding amount. If the materials are transported and added in batches, the furnace door will be open for a long time, and the splashing of aluminum will pose a safety hazard. In addition, it will increase energy consumption, and it is difficult to ensure the uniformity of feeding by repeatedly adding materials back and forth. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a furnace front bulk material feeding device, which can accurately and evenly add a specified amount of material into the smelting furnace, and avoid the phenomena of furnace front being dirty and messy, and furnace door being open for a long time.

[0004] Technical solution: To achieve the above objectives, the present invention provides a furnace front bulk material feeding device, including a moving mechanism, a hopper at the upper part of the moving mechanism, the hopper being able to slide horizontally so that its discharge end can extend into the furnace cavity; a pusher is slidably arranged inside the hopper, and after the discharge end of the hopper extends into the furnace cavity, the pusher can slide and push the material so that the material is pushed out from the discharge end of the hopper.

[0005] Furthermore, a weighing sensor is provided in the area of ​​the moving mechanism that carries the hopper, which can weigh the hopper and the material inside it when the hopper is completely placed on the moving mechanism.

[0006] Furthermore, the discharge end of the hopper is provided with a baffle, which is in contact with the port surface of the discharge end when closed.

[0007] Furthermore, the upper part of the baffle is hinged to the upper edge of the discharge end port, so that the baffle fits against the port surface of the discharge end under its own weight.

[0008] Furthermore, the moving mechanism is provided with a first driving device for driving the hopper to slide; the hopper is provided with a second driving device for driving the pusher to slide; and a third driving device is also provided for opening and closing the baffle.

[0009] Furthermore, the first driving device, the second driving device, and the third driving device all employ hydraulic cylinders.

[0010] Furthermore, a distance sensor is provided at the discharge end of the hopper to measure the distance between the discharge end of the hopper and the feeding port of the furnace cavity; the distance sensor is electrically connected to the first driving device through a controller, and the weighing sensor is electrically connected to the first driving device through a controller.

[0011] Furthermore, the ranging sensor is electrically connected to the second driving device via a controller; the ranging sensor is also electrically connected to the third driving device via a controller.

[0012] Furthermore, the third driving device can provide support or lifting force to the baffle when the baffle is flipped open to any angle.

[0013] Beneficial Effects: This utility model provides a furnace-front bulk material feeding device capable of transporting large quantities of material at a time and uniformly feeding it into the furnace cavity. Pre-weighing ensures no material spillage during transport and feeding, guaranteeing accurate feeding and maintaining a clean furnace area. Furthermore, the short feeding speed reduces furnace door opening time, minimizing the safety risk of molten aluminum splashing and reducing energy consumption. In summary, it accurately and uniformly adds a specified amount of material into the smelting furnace, avoiding furnace-front mess and prolonged furnace door opening. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of one embodiment of the feeding device of this utility model. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figure 1The aforementioned furnace-front bulk material feeding device includes a moving mechanism 1. A hopper 2 is mounted on the upper part of the moving mechanism 1. The hopper 2 can slide horizontally, allowing its discharge end to extend into the furnace chamber 3. A pusher 4 is slidably mounted inside the hopper 2. After the discharge end of the hopper 2 extends into the furnace chamber 3, the pusher 4 can slide and push the material, causing the material to be ejected from the discharge end of the hopper 2. The moving mechanism 1 can be a rail-mounted or trackless vehicle; preferably, an AGV (Automated Guided Vehicle) trackless flatbed vehicle can be used, enabling omnidirectional automatic cruising movement and automatic movement between multiple points to achieve feeding operations for multiple smelting furnaces. After moving to the corresponding smelting furnace position, the hopper position is first adjusted so that its discharge end aligns perfectly with the furnace inlet. Then, after the furnace door is opened, the end of the hopper is inserted into the furnace cavity, and the material is pushed into the furnace cavity by the pusher. This prevents material from scattering outside the furnace. The pusher can adopt a common pusher plate structure, which can completely push out the material in the hopper, thus ensuring the accuracy of the amount of material added in a single operation. In addition, by allowing the hopper to extend to the deepest part of the furnace cavity, the hopper and the pusher can move synchronously and at a uniform speed during feeding, ensuring that the material in the hopper is completely pushed out when it reaches the deepest part of the furnace cavity, thereby achieving uniform material distribution.

[0017] A weighing sensor 11 is installed in the area of ​​the moving mechanism 1 that supports the hopper 2. This sensor can weigh the hopper 2 and the material inside it when the hopper 2 is completely placed on the moving mechanism 1. It can automatically weigh an appropriate amount of material according to the actual condition of the smelting furnace, further ensuring the accuracy of the material feed.

[0018] Preferably, the discharge end of the hopper 2 is provided with a baffle 5, which fits against the port surface of the discharge end when closed. This can block the discharge port, preventing material from scattering during the handling process after weighing, especially small-volume bulk materials. Therefore, even when adding a large amount of material, it can be weighed and added in one go without scattering, avoiding impact on the addition amount and preventing a messy environment in front of the furnace.

[0019] In one embodiment, the upper part of the baffle 5 is hinged to the upper edge of the discharge end port, so that the baffle 5 fits against the port surface of the discharge end under its own weight. Alternatively, it can be magnetically attached and fixed. During feeding, the material is pushed by the pusher, which generates a pushing force on the baffle 5, thereby overcoming gravity and pushing the baffle open to complete the feeding. The pushing speed of the pusher can control the opening of the baffle, thereby controlling the feeding speed and improving the uniformity of feeding.

[0020] The moving mechanism 1 is provided with a first driving device 12 for driving the hopper 2 to slide; the hopper 2 is provided with a second driving device 22 for driving the pusher 4 to slide, and a third driving device is also provided for opening and closing the baffle 5.

[0021] In one embodiment, the first driving device 12, the second driving device 22, and the third driving device are all hydraulic cylinders, and all use limit switches to control the start and stop of the pushing action. After weighing the preset amount of material, the moving mechanism 1 first travels to the position corresponding to the melting furnace, then the furnace door is opened, and the hydraulic cylinder pushes the hopper into the furnace cavity. Inside the furnace cavity, the hydraulic cylinder drives the baffle 5 to open, and then the hydraulic cylinder drives the pusher to push the material out, completing the material feeding.

[0022] In another embodiment, a distance sensor 21 is provided at the discharge end of the hopper 2 to measure the distance between the discharge end of the hopper 2 and the feeding port of the furnace cavity 3. The distance sensor 21 is electrically connected to the first driving device 12 through a controller, and the weighing sensor 11 is electrically connected to the first driving device 12 through a controller. The amount of material in the hopper and the position of the feeding device itself relative to the smelting furnace are used as two data points to determine whether the hopper extends. That is, only when the amount of material in the hopper meets the feeding range requirements, and the relative position of the hopper 2 and the smelting furnace is adjusted by the moving mechanism 1 to be appropriate, can the first driving device 12 be triggered to start, causing the hopper to extend. This ensures that the weighing amount can meet the feeding requirements and that the weighed material can be accurately and completely fed into the furnace without spillage.

[0023] The ranging sensor 21 is electrically connected to the second driving device 22 via a controller; the ranging sensor 21 is also electrically connected to the third driving device via a controller. Based on this, the baffle can be opened and the material pushed in only after the discharge end of the hopper is completely inside the furnace, avoiding material spillage and loss.

[0024] The third driving device can provide support or lift to the baffle 5 when it is flipped open to any angle. This allows for stepless adjustment of the baffle 5's opening degree, thus controlling the material delivery rate and enabling more precise control over the uniformity of material delivery.

[0025] In actual feeding, after weighing the preset amount of material, the moving mechanism 1 travels to the position corresponding to the smelting furnace. After weighing the preset amount of material, the moving mechanism 1 travels to the position corresponding to the smelting furnace. When the distance signal fed back by the distance sensor 21 is appropriate, the first driving device is triggered to push the hopper into the furnace cavity. When the discharge end of the hopper just enters the furnace cavity, the third driving device is triggered to open the baffle to the appropriate angle. Then, the first driving device and the second driving device are triggered to advance at their respective speeds to complete the uniform feeding of material.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
