Problems solved by technology
However, in the actual industrial production process, it is impossible to carry out online accurate continuous detection of the recovery rate of magnetic separation tubes.
Some existing detection methods for the recovery rate of magnetic separation tubes need to detect the recovery rate of magnetic separation tubes based on continuous huge data combing and parameter identification. The calculation is complicated and is not conducive to online detection.

Embodiment Construction
[0050] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples.
[0051] figure 1 It is a shaft furnace roasting process. The furnace is divided into three parts from top to bottom: pre-tropical zone, heating zone and reduction zone. The whole system is divided into ore feeding system, gas combustion system, high temperature reduction system and cooling removal system in turn, and its main functions are:
[0052] (1) Ore feeding system: This system includes ore transmission and preheating process. The ore is transported to the furnace top storage tank through the distribution system, and falls into the furnace through the funnel. When the material level reaches the predetermined height, the cloth trolley stops conveying. In the preheating zone, the ore exchanges heat with the bottom-up heating zone outlet gas to preheat the ore so tha...

An online real-time detection system and method for shaft furnace magnetic selection tube recovery rate, belonging to the field of shaft furnace roasting production. The system includes an information acquisition module, an air flow calculation module, a combustion gas flow calculation module, a reduction gas flow calculation module, a combustion chamber temperature calculation module and a magnetic separation tube recovery rate calculation module; the method includes the steps of obtaining initial information, calculating the air flow steps, steps for calculating the combustion gas flow rate, steps for calculating the reduction gas flow rate, steps for calculating the combustion chamber temperature, and steps for calculating the magnetic separation tube recovery rate. The present invention calculates the real-time magnetic separation tube recovery rate based on the real-time combustion chamber temperature, reduction gas flow rate, and ore removal time. By comparing with the actual value of the magnetic separation tube recovery rate, it is found that the magnetic separation tube recovery rate calculated by the present invention is consistent with The actual values are not much different, have high accuracy, and the detection system and method are simple.
Description
technical field [0001] The invention belongs to the field of shaft furnace roasting production, and in particular relates to an online real-time detection system and method for the recovery rate of a shaft furnace magnetic separation tube. Background technique [0002] The main technological indicator of the shaft furnace reduction roasting process is the recovery rate of the magnetic separation tube, which reflects the quality and efficiency of ore roasting. The recovery rate of the magnetic separation tube needs to meet certain process requirements to enable the subsequent magnetic separation operation to select a qualified concentrate. Therefore, it is the key to the whole beneficiation process to ensure that the recovery rate of the magnetic separation tube reaches a certain index during the reduction roasting process of the shaft furnace. However, in the actual industrial production process, the online and accurate continuous detection of the magnetic separation tube r...
