Electrical management system for fuel heat conduction oil furnace

Abstract

The invention discloses an electrical management system for a fuel heat conduction oil furnace. The system comprises a heat conduction oil furnace electrical cabinet, a cloud server, remote monitoringequipment, switching value signal equipment, analog quantity signal acquisition equipment and execution equipment. A PLC, an intelligent industrial controller and a power distribution loop are arranged in the heat conduction oil furnace electrical cabinet. A touch screen is arranged on a heat conduction oil furnace electrical cabinet door. The power supply voltage of the PLC, the touch screen andthe intelligent industrial controller is DC 24V. The power distribution loop distributes power to each electrical device in the heat conduction oil furnace electrical cabinet. According to the invention, the PLC is used for replacing a temperature, pressure and liquid level control display and a high-limit temperature controller on an electric cabinet operation panel of a traditional fuel heat conduction oil furnace, a temperature transmitter, a pressure transmitter, a liquid level transmitter, a voltage transmitter and a current transmitter are added, a combustor circuit board and a programcontroller are replaced, the defects that a traditional electrical system is poor in reliability and unsafe, and remote monitoring, maintenance and upgrading cannot be achieved are overcome, and the functions of the heat conduction oil furnace electrical control system are greatly enhanced to be an electrical management system platform.

Description

technical field [0001] The invention relates to the technical field of heat-conducting oil furnace monitoring, in particular to an electrical management system for a fuel-fired heat-conducting oil furnace. Background technique [0002] Heat conduction oil furnace is heating equipment in asphalt pavement construction. It is very critical in asphalt mixing equipment, asphalt modification equipment and asphalt emulsification equipment, but most people don't understand it, so they often ignore it. When it breaks down and seriously affects production followed. In actual operation, the heat-conducting oil furnaces of asphalt mixing equipment and other equipment are often relocated with the flow of construction units, and the electrical cabinet is installed under the legs of the heat-conducting oil expansion tank. Electricity is seriously loosened, falling off, soaked in oil, wire insulation becomes soft and swollen, and there are many and messy control lines in the traditional el...

AI Technical Summary

Problems solved by technology

The heat-conducting oil furnace needs to work continuously during the asphalt pavement construction season. During the operation period, two people are generally arranged to be on duty, not including maintenance personnel. Equipment management personnel need to make frequent inspections during critical construction periods. Production

Don't talk about remote monitoring of the heat transfer oil furnace. In the past, people wanted to monitor the heat transfer oil furnace in the operation room of the asphalt mixing plant. Historical temperature data, or ideas such as upgrading the control system, are even more impossible to achieve
