Electromagnetic wave conduction oil heater

Abstract

The invention relates to an electromagnetic wave conduction oil heater. The electromagnetic wave conduction oil heater is characterized by being provided with a cylindrical shell, wherein a cylindrical middle clapboard and a cylindrical inner clapboard are arranged in the shell; the cylindrical middle clapboard is coaxially fixed with a cylinder wall and is connected with an upper cover of the shell; a plurality of overflowing openings are formed at the periphery of the top of the cylindrical middle clapboard; the cylindrical inner clapboard is in sealed connection with the upper cover of the shell; the space inside the cylinder wall is divided into an outer cavity, a middle cavity and an inner cavity by the middle clapboard and the inner clapboard; more than one layer of electromagnetic wave heating tubes which are arranged continuously and vertically are arranged in each cavity; the lower end of each electromagnetic wave heating tube is extended to the bottom of the cylinder wall, and an upper wiring terminal of each electromagnetic wave heating tube is extended out of the upper cover of the shell and is connected with a power supply wiring board; a stream splitting cover which is covered at the bottom edge of the cylindrical middle clapboard is arranged at the bottom inside the shell; the bottom of the shell is connected with a conduction oil inlet; the upper part of the inner cavity is connected with a conduction oil outlet; the bottom of the stream splitting cover is provided with a discharge port; a heat insulation layer is arranged outside the shell; and the electromagnetic wave heating tubes are infrared electromagnetic wave heating tubes. The electromagnetic wave conduction oil heater has the advantages of precisely controlling the heating temperature, saving energy, reducing consumption and ensuring safe production.

Description

technical field [0001] The invention relates to a heat-conducting oil heating device, which is mainly used for heating the heat-conducting oil used for tracing the heat of pipelines, valves, pumps and other facilities passing through asphalt on an asphalt production line, in particular to an electromagnetic wave heat-conducting oil heater. Background technique [0002] In the asphalt manufacturing industry, especially the rubber powder modified asphalt manufacturing industry that has emerged rapidly in recent years, in the production line, the matrix asphalt as raw material and the rubber powder modified asphalt as finished product are transported along the pipeline, in order to ensure smooth flow of asphalt materials For smooth transportation, heat-conducting oil must be used to heat the pipelines, valves, pumps and other facilities through which the asphalt material flows. Generally, the heat-conducting oil is heated to 200-220°C first, and then the heat-conducting oil circ...
