Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical industry, and specifically relates to an intelligent quantitative batching system. Background Art

[0002] The raw materials for ferrosilicon smelting are silica, coke and silicon steel sheets, which are added into the submerged arc furnace in a predetermined proportion during the smelting process for smelting. In the prior art, the raw materials are first poured into the raw material feed hopper respectively, and then directly dropped into the batching hopper after being weighed by a weighing mechanism. When the raw materials entering the batching hopper reach a predetermined proportion, the control valve at the lower end of the raw material feed hopper is closed, and the batching hopper control valve is opened, and the batched raw materials are sent to the submerged arc furnace for smelting through a conveying device. In this process, the raw materials are directly mixed into the submerged arc furnace after one mixing, which results in uneven mixing and uneven quality and performance of various parts of the produced ferrosilicon blocks.

[0003] Chinese utility model patent CN 214553117 U discloses a ferrosilicon raw material batching device, which realizes secondary mixing of the batching by a conveying device and a batching device, thereby ensuring uniform mixing of the raw materials. However, when the ferrosilicon raw material batching device conveys materials into a hopper, it can only convey materials of a predetermined mass, and its hopper cannot realize material buffering and uninterrupted conveying. This is because once the material is conveyed to the hopper uninterruptedly, while the material in the hopper is being discharged, the weighing unit may detect that the weight of the raw materials in the hopper is increasing, and the conveyed material may also impact the hopper, causing the weighing unit to read incorrectly, so that the material cannot be accurately proportioned.

[0004] Therefore, how to provide an intelligent quantitative batching system that can achieve buffering and weighing of raw materials while ensuring uninterrupted transportation of raw materials has become a technical problem that people in this field need to solve. Utility Model Content

[0021] Example

[0022] like Figure 1-2 As shown, this embodiment discloses an intelligent quantitative batching system, including four raw material bins, a vibrating feeder 4, a batching mechanism, a conveying mechanism and a control mechanism, the control mechanism includes a weighing sensor 5 and a PLC, the four raw material bins are arranged on the ground, respectively used to hold silica, oxide scale, silicon steel sheet, and coke raw materials, the batching mechanism is arranged in a pit 22 between the raw material bins, the vibrating feeder 4 is arranged between the raw material bin and the batching mechanism, and is used to feed the raw material bin to the batching mechanism, and the conveying mechanism is arranged next to the batching mechanism.

[0023] The raw material warehouse includes a first warehouse body 1, a second warehouse body 2 and a first bracket 3. The first warehouse body 1 is fixed at the top of the first bracket 3, and the second warehouse body 2 is located directly below the first warehouse body 1. A fixed plate 6 is arranged around the side wall of the second warehouse body 2. The fixed plate 6 is arranged on the first bracket 3 through a weighing sensor 5. An electric discharge valve 7 is arranged at the upper end of the discharge port of the first warehouse body 1, and the tail end of the discharge port of the first warehouse body 1 is slidably sleeved in the feed port of the second warehouse body 2. A dustproof exhaust port is arranged at the top of the second warehouse body 2, and a discharge port of the second warehouse body 2 is provided with a discharge switch. The discharge switch includes a hydraulic cylinder 8 and a baffle plate 9 slidably arranged at the discharge port, and the baffle plate 9 is fixedly connected to the piston rod of the hydraulic cylinder 8.

[0024] In this embodiment, the electric discharge valve 7, the vibrating feeder 4, the batching mechanism and the weighing sensor 5 are all electrically connected to the PLC, and the hydraulic cylinder 8 is electrically connected to the PLC through the hydraulic valve.

[0025] When batching, the electric discharge valve 7 is opened first, and the raw materials transported into the first bin body 1 can enter the second bin body 2 through the electric discharge valve 7. When the weight of the second bin body 2 reaches a predetermined mass, the electric discharge valve 7 is closed. At this time, the materials can still be continuously fed into the first bin body 1. Since the discharge port of the first bin body 1 is slidably arranged in the feed port of the second bin body 2, the raw materials that need to be weighed and distributed in the second bin body 2 will no longer be affected by continuous feeding. The replenishment of the second bin body 2 can be controlled by PLC within the time when the second bin body 2 does not need to discharge. By dividing the raw material bin into the first bin body 1 and the second bin body 2, the quality of the raw materials in the second bin body 2 can be weighed to achieve accurate unloading control of the raw materials, and the raw materials can be cached. At the same time, the reading of the weighing sensor 5 is avoided to change at all times due to uninterrupted feeding, and the raw materials are avoided to be continuously fed into the feed bin during unloading, causing the raw materials to have an impact on the weighing sensor, resulting in inaccurate data display.
