Problems solved by technology

At present, the thickness of the furnace lining is thickened or high insulation materials are used, so that the volume of the boiler is increased, the cost is high, the temperature cannot be adjusted at will, the high temperature causes waste of heat sources, and some furnace walls are broken due to the local temperature of the heat exchange surface is too high Or perforation; the outer surface of the boiler is corroded by the action of oxygen in the air and the action of combustion products, and the corrosion rate increases with the increase of the air supply coefficient and the surface temperature of the tube; but the temperature is too low to achieve the heating effect

Embodiment Construction

[0014] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0015] Such as figure 1 As shown, a heating device includes a housing 1, and a corrugated heating rod 2 is arranged inside the housing 1, and the heating is uniform and the heating speed is fast. The heating rod can be placed in the center of the mold and poured into the molten metal. Take it out after cooling, and the outer circle is processed by a lathe. The heating rod 2 is provided with a metal sleeve 3, and the housing 1 is provided with a controller 4, a temperature sensor 5, and a buzzer 6. The controller 4 is electrically connected with the heating rod 2, the temperature sensor 5, and the buzzer 6.

Abstract

The invention relates to a heating device which comprises a housing, wherein a corrugated heating rod is arranged in the housing, a metal cover is arranged outside the heating rod, a controller, a temperature sensor and a buzzer are arranged outside the housing, and the controller is electrically connected with the heating rod, the temperature sensor and the buzzer. Air is isolated from the heating rod by the heating device disclosed by the invention, thereby prolonging the service life of the heating rod. The heating device has the advantages of high heating speed, light weight and small volume. A higher temperature signal is transmitted to the controller by the temperature sensor, so that a circuit is cut off by the controller while the buzzer makes a sound, an operator can be facilitated to take measures, potential safety hazards are avoided, and the service life is prolonged.

Description

technical field [0001] The invention relates to chemical production equipment, in particular to a heating device. Background technique [0002] The existing heating pipe has cracks due to the ceramic material after being heated. After a period of use, the thermal resistance wire is oxidized and burnt and scrapped. The service life is short and needs to be replaced frequently. In order to ensure that a certain temperature is reached, the surface temperature of the furnace shell should be as low as possible. At present, the thickness of the furnace lining is thickened or high insulation materials are used, so that the volume of the boiler is increased, the cost is high, the temperature cannot be adjusted at will, the high temperature causes waste of heat sources, and some furnace walls are broken due to the local temperature of the heat exchange surface is too high Or perforation; the outer surface of the boiler is corroded by the action of oxygen in the air and the actio...
