[0030] In this embodiment, the storage bin 1 is used to store different kinds of raw materials. These raw materials are various materials required in the production process of the ore-bearing furnace 5. There are multiple storage bins 1 to meet the needs of storing multiple raw materials. A discharge port 11 is provided at the bottom of each storage bin 1, and a material level meter 12 is provided inside the storage bin 1 to monitor the inventory of raw materials in the storage bin 1 in real time to ensure timely replenishment. A first discharging mechanism 13 is provided at the bottom of the storage bin 1 to control the transfer of raw materials from the storage bin 1 to the metering bin 2. A first weight sensor 21 is provided inside the metering bin 2. The number of metering bins 2 is the same as that of the storage bin 1. The metering bin 2 is provided after the storage bin 1. The metering bin 2 is used to accurately measure the weight of the raw materials to ensure accurate control of the input amount of each raw material. A second discharging mechanism 22 is provided at the bottom of the metering bin 2 to transfer the measured raw materials to the batching and mixing device 3. The batching and mixing device 3 is provided after the metering bin 2 to mix the raw materials measured by different metering bins 2 to ensure the uniformity of the raw materials and meet the production needs of the ore-bearing furnace. A third discharging mechanism 35 is provided at the bottom of the batching and mixing device 3 for conveying the mixed raw materials to the submerged arc furnace 5. The conveying device conveys the materials from the batching and mixing device to the submerged arc furnace to ensure a continuous supply of raw materials.

[0031] The workflow of the whole system is as follows: different raw materials are first stored in different storage bins 1. When they are needed, the first discharging mechanism 13 transports the raw materials to the corresponding metering bin 2 for metering. The metered raw materials are then transported to the batching and mixing device 3 for mixing through the second discharging mechanism 22. Finally, the mixed raw materials are transported to the ore-fired furnace 5 for production through the first conveying device 42. The material level meter 12 is used to measure the amount of material in the storage bin 1. When the material level meter 12 detects that there is too little material in the storage bin 1, it can remind the staff to replenish the material.

[0032] Through this embodiment, the automation level of the system is improved, and the batching accuracy and batching efficiency can be improved.

[0033] Furthermore, if Figure 2 , an optional embodiment, in the figure, the x-th storage bin represents different storage bins, such as the third storage bin, the fourth storage bin, etc., the system also includes a controller 6 and a host computer 7, the controller 6 is electrically connected to each of the level meters 12, each of the first discharging mechanisms 13, each of the first weight sensors 21, each of the second discharging mechanisms 22, each of the third discharging mechanisms 35, and each of the conveying devices.

[0034] Through this optional embodiment, the function of the ore-bearing furnace production batching system of the present application is further expanded and improved. By introducing the controller 6 and the host computer 7, the whole system realizes a higher level of automatic control and monitoring. In this embodiment, the controller 6 is the core control unit of the whole system, responsible for receiving and processing signals from various components, and controlling the actions of various components according to the preset program or the instructions of the host computer 7.

The controller 6 is electrically connected to each first discharging mechanism 13 to control the transfer of raw materials from the storage bin 1 to the metering bin 2. The controller 6 is electrically connected to each first weight sensor 21 to obtain the precise weight data of the raw materials in the metering bin 1. The controller 6 is electrically connected to each second discharging mechanism 22 to control the transfer of raw materials from the metering bin 2 to the batching and mixing device 3. The controller 6 is electrically connected to each third discharging mechanism 35 to control the output of the mixed raw materials from the batching and mixing device 3. The controller 6 is electrically connected to the first conveying device 41 to ensure the continuous and stable delivery of the raw materials output from the batching and mixing device 3 to the ore-fired furnace 5. The host computer 7, as the human-machine interface and advanced monitoring center of the system, can display the real-time operating status of the system, the working conditions of each component, the inventory and flow of raw materials and other information. At the same time, the operator can remotely monitor and operate the system through the host computer. The host computer 7 is electrically connected to the controller 6, can receive data from the controller 6, and send the operator's instructions to the controller 6, so as to realize remote monitoring and operation of the entire system. The controller of the present invention can be selected as a programmable logic controller PLC.

[0035] Through this embodiment, the system can automatically complete the metering, mixing and conveying of raw materials according to the preset program or the instruction of the host computer 7, reducing the intervention of manual operation and improving production efficiency. Through real-time monitoring of components such as the material level meter 12 and the weight sensor, the system can timely adjust the input amount and mixing ratio of the raw materials to ensure the stability of the production process and the quality of the product.

[0039] The mixing bin 31 is the main place for mixing raw materials. The mixing bin 31 can accommodate a variety of raw materials transferred from the metering bin, and achieve uniform mixing of the raw materials through the internal agitator 32. The agitator 32 is a key component in the mixing bin. Through rotation or stirring, the raw materials are fully mixed in the mixing bin. The type of the agitator 32 can be paddle type, spiral type, etc. Its working principle is mainly to drive the agitator to rotate through a motor to generate shear force and convection force, so that the raw materials form flow and circulation in the mixing bin, thereby achieving uniform mixing. The buffer bin 33 is located below the mixing bin 31 and is used to temporarily store the mixed raw materials. The second weighing sensor 34 is installed at the bottom of the buffer bin 31 to monitor the weight of the raw materials in the buffer bin 33. When the raw materials flow from the mixing bin 31 into the buffer bin 33, the second weighing sensor 34 will measure the weight of the raw materials in the buffer bin 33, so as to determine whether the amount of materials entering the ore furnace 5 reaches the set standard.

[0040] Further, in possible situations, the storage bin 1, the metering bin 2, and the batching and mixing device 3 are arranged at a long distance, and materials need to be transported by a conveying device.
