Material weighing and variable-speed conveying system for blast furnace

Abstract

The invention discloses a material weighing and variable-speed conveying system for a blast furnace, which is well applied in the fields of new energy and energy-saving low carbon. The material weighing and variable-speed conveying system comprises a device frame, a bin and a material conveying device and is characterized by also comprising a PLC (Programmable Logic Controller) as well as a control cabinet, an AD (Analog-Digital) module, an AD-PT module, a weighing sensor, an optoelectronic switch, a temperature sensor and a material heater which are coencted with the PLC, wherein the weighing sensor is arranged at the bottom of the bin; the temperature sensor and the material heater are arranged inside the bin; the optoelectronic switch is arranged on the side wall of the bin; and the control cabinet, the PLC, the AD module and the AD-PT module are arranged on the device frame. The invention provides an analog quantity signal processing device which can be used for both teaching and practical training, i.e., the material weighing and variable-speed conveying system for the blast furnace has the advantages of being high in precision of temperature control, convenient to use and the like and greatly improves the learning interest and the actual operation capability of students, thus enabling the students to comprehensively know and master the integrated techniques of mechanics and electronics.

Description

technical field [0001] The present invention relates to the technical field of mechatronics, in particular to a training and teaching research and development device with a relatively high degree of automation, which is mainly used in various factories and mines for the production of various granular, blocky or powdery, etc. A device for long-distance vertical or slope transportation of bulk materials. Background technique [0002] With the continuous improvement of the automation level and degree in the modern control process, and the continuous accuracy and correctness of the control precision. This puts forward higher requirements and levels for the processing of analog signals. At present, many teaching devices are more focused on the processing of switching signals, and do not consider much about the process and methods of analog signal processing; in addition, the existing teaching Methods and approaches are also difficult for students to understand and master the spe...

This puts forward higher requirements and levels for the processing of analog signals. At present, many teaching devices are more focused on the processing of switching signals, and do not consider much about the process and methods of analog signal processing; in addition, the existing teaching Methods and approaches are also difficult for students to understand and master the specific acquisition and control process of analog signals

Students generally form a simple superficial understanding and a working method of their own illusions through the teacher's abstract explanation or watching the specific products and pictures of the analog module, but they do not understand the specific use method and process, nor can they Analyze the actual operation and control effect of the analog module. These factors have greatly weakened the overall teaching effect and the scope of the training content, and also reduced the students' learning enthusiasm.

At the same time, during the material conveying process, the heating control of the material is performed, and the control accuracy is not high, which often causes uneven heating of the front and rear materials, which brings great inconvenience to the subsequent processing and production.
