Abstract

An explosion-proof waterproof electric heating plate relates to the technology of heating appliances and relates to the technical field of oil temperature keeping of gas stations. The explosion-proof waterproof electric heating plate is characterized in that the upper end of an aluminum plate is provided with a groove, a binding box is hermetically welded in the groove, the upper end of the binding box is in threaded connection with a binding box cover, the binding box cover is provided with an axial central hole, a cylindrical sealing ring is arranged in the axial central hole, a pressing nut is arranged at the upper end of the cylindrical sealing ring and in threaded connection on the binding box cover, and the center of the pressing nut is also provided with an axial hole. An annular heating coil component is packaged in the aluminum plate, and two ends of the annular heating coil component are respectively disposed in an inner cavity of the binding box. The explosion-proof waterproof electric heating plate is fine in sealing and is explosion-proof and water proof when being disposed in an oil body of an oil tank, and high in safety performance.

Description

technical field [0001] The invention relates to the production technology of heating appliances, and also relates to the technical field of oil temperature maintenance in gas stations. Background technique [0002] The gas station needs to supply oil at any time all year round. Since the oil depot of the gas station is set up outdoors, due to the influence of the lower ambient temperature in winter, a heater must be used to maintain the oil temperature and prevent freezing. [0003] The existing heating measure is to directly place electric heating pipes in the oil depot for heating with electricity, which is extremely dangerous, prone to conduction, and explosion accidents. Contents of the invention [0004] The purpose of the invention is to provide a safe and power-saving explosion-proof and waterproof electric heating plate for the oil depot. [0005] In the present invention, a groove is set on the upper end of the aluminum plate, the junction box body is sealed and ...
