They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] This utility model provides a technical solution: an automatic ore feeding device, which includes a conveying component, a funnel 1, a conveying component, and a fluidized bed furnace 2. The conveying component is used to transport sulfur concentrate. The funnel 1 is used to load the sulfur concentrate transported by the conveying component and control the discharge flow rate of the sulfur concentrate. The conveying component is located at the discharge port of the funnel and is used to transfer the sulfur concentrate discharged from the funnel 1. The fluidized bed furnace 2 is located at the inlet of the conveying component and is used to heat the sulfur concentrate transferred by the conveying component.

[0033] Specifically, the handling components of this device can utilize fully automatic bridge grab cranes, automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and other equipment that can handle sulfur concentrate without human intervention. These devices, programmed autonomously, can navigate, avoid obstacles, and transport the sulfur concentrate into hopper 1, ensuring no ore shortages occur. Furthermore, hopper 1 is a conical hopper with a conical bottom, allowing the sulfur concentrate to flow smoothly within it, preventing accumulation and reducing the risk of blockages. The discharge flow rate of the sulfur concentrate can also be controlled by adjusting the size of the bottom outlet. In actual production, the entire production line from sulfur concentrate to production is relatively long, often requiring further transfer of the sulfur concentrate. Therefore, the transfer components of this device can utilize conveyor belts, rail-guided vehicles (RGVs), and other equipment that can handle the sulfur concentrate without human intervention. For example, if a conveyor belt is used, it is installed between the discharge port of hopper 1 and the feed port of fluidized bed furnace 2. If a rail-guided vehicle is used, a track is set between hopper 1 and fluidized bed furnace 2, with a shuttle car capable of reciprocating motion on the track. In summary, in this 24-hour uninterrupted production operation, this device can greatly reduce the intensity of manual labor and avoid production interruptions due to human negligence, thereby achieving stable ore supply and improving production efficiency.

[0034] As an optional implementation, in some embodiments, a blower 6 is also included, the air outlet of which is connected to the bottom of the fluidized bed furnace 2 via a pipe. The blower 6 can deliver air into the furnace chamber, increasing the oxygen content inside the furnace and promoting more complete fuel combustion, thereby improving thermal efficiency.

[0035] In the above embodiment, an oxygen transmitter 7 is further included. The top of the fluidized bed furnace 2 has a gas outlet 8, and the oxygen transmitter 7 is used to detect the oxygen content of the gas at the gas outlet 8. Since combustion efficiency in the fluidized bed furnace 2 is closely related to oxygen concentration, installing the oxygen transmitter 7 allows for adjustment of the oxygen supply during combustion based on real-time monitored oxygen concentration data, ensuring thorough mixing of fuel and oxygen and improving combustion efficiency. This not only helps reduce fuel consumption but also lowers pollutant emissions, achieving the goal of energy conservation and emission reduction.

[0036] In the above embodiments, a temperature transmitter 9 is further included, which is used to detect the temperature inside the fluidized bed furnace 2. The temperature transmitter 9 can monitor temperature changes inside the fluidized bed furnace 2 in real time, allowing operators to accurately understand the temperature conditions inside the furnace and thus perform precise temperature control, thereby ensuring combustion efficiency and product quality. Simultaneously, it can also promptly detect potential safety hazards; if the temperature exceeds the set range, operators can immediately take measures to prevent equipment damage or safety accidents.

[0037] In the above embodiments, a pressure transmitter 10 is further included, which is used to detect the pressure inside the fluidized bed furnace 2. The pressure transmitter 10 can monitor pressure changes inside the fluidized bed furnace 2 in real time, allowing operators to promptly understand the pressure status inside the furnace and make necessary adjustments and controls to ensure that the furnace pressure operates within a safe and stable range. Simultaneously, it can also promptly detect potential safety hazards, as excessively high or low pressure may damage the equipment or cause safety accidents.

[0038] In the above embodiments, a level gauge 11 is further included, with its probe facing the inside of the funnel 1. The level gauge 11 is used to detect the height of the sulfur concentrate in the funnel 1. The level gauge 11 can monitor the height of the sulfur concentrate in the funnel 1 in real time, ensuring that the sulfur concentrate in the funnel 1 is neither excessive nor insufficient, thus guaranteeing the continuity and stability of the production process. Furthermore, the level gauge 11 may include, but is not limited to, radar level gauges, ultrasonic level gauges, etc.

[0039] In the above embodiments, a DCS is further included. The DCS is connected to the controllers of the conveyor, the blower 6, the oxygen transmitter 7, the temperature transmitter 9, the pressure transmitter 10, and the level gauge 11. The DCS, short for Distributed Control System, connects the signals from the conveyor, blower 6, oxygen transmitter 7, temperature transmitter 9, pressure transmitter 10, and level gauge 11 to the DCS. These signals are then analyzed and controlled according to a preset program to achieve the automatic and smooth conveying of sulfur concentrate to the fluidized bed furnace 2 for heating and production.

[0040] As an optional implementation, in some embodiments, the fluidized bed furnace 2 has a slag discharge port 3 and an inspection hole 5. A tube sheet 4 is provided inside the fluidized bed furnace 2 near the slag discharge port 3. The tube sheet 4 has several ventilation holes and is horizontally arranged. The inspection hole 5 is located at the bottom of the fluidized bed furnace 2.

[0041] Specifically, the ventilation holes on the tube sheet 4 allow the air supplied by the blower to be evenly distributed throughout the fluidized bed furnace 2, ensuring complete combustion of the sulfur concentrate. Simultaneously, the tube sheet 4 helps enhance the structural rigidity of the entire furnace body. Furthermore, during operation, ash, stones, iron parts, and other debris may accumulate at the bottom of the fluidized bed furnace 2, potentially affecting combustion efficiency and stability. The inspection holes 5 located at the bottom allow maintenance personnel to easily access the bottom of the furnace for cleaning and maintenance, ensuring furnace cleanliness and combustion efficiency.

[0042] As an optional implementation, in some embodiments, a disc feeder 13 is also included, which is disposed between the discharge port of the hopper 1 and the conveyor. The disc feeder 13 can evenly distribute the sulfur concentrate onto the conveyor for transport, further improving the stability of the device.

[0043] As an optional implementation, in some embodiments, the transport component is a bridge grab crane 14, which is installed in the ore bin 15. The conveying component includes several conveyor belts, with two adjacent conveyor belts connected end-to-end. Preferably, the device uses a bridge grab crane 14, which has a powerful lifting capacity and efficient loading and unloading speed, enabling rapid grabbing and transport of materials such as ore. Therefore, installing a bridge grab crane 14 in the ore bin 15, which stores sulfur concentrate, can significantly reduce the time and labor costs of manual loading and unloading, while improving overall loading and unloading efficiency. The conveying component preferably uses conveyor belts. Depending on the transfer distance, multiple conveyor belts can be connected for transport. This way, even if the conveyor belts wear out and need replacement, only the corresponding conveyor belt needs to be replaced, greatly reducing maintenance costs. In this embodiment, a first conveyor belt 16 and a second conveyor belt 17 are used in conjunction for transfer.
