Automatic instrument for petroleum refining

Abstract

The invention discloses an automatic instrument for petroleum refining and relates to the technical field of petroleum refining. The automatic instrument includes an instrument panel. An instrument case with an instrument control chip inside is fixedly connected to the back surface of the instrument panel. A display screen is fixedly inlaid in the upper part of the front surface of the instrumentpanel. A menu option key is fixedly connected to the lower part of the front surface of the instrument panel. A top plate is driven by a connecting rod 3 to rotate clockwise around a pin roll at the center, so that a ventilation space is formed between the group consisting of a side plate 1, a side plate 2, and a side plate groove and the group consisting of the top plate and a top groove. Thus, the air flows through the gaps among the side plate 1, the side plate 2, and the side plate groove to circulate the internal heat. Therefore, the heat is raised so as to be dissipated through the ventilation space between the top plate and the top groove, thereby achieving the internal cyclical heat dissipation and elimination and improving the heat dissipation effect of the device. In addition, the rotation of the side plate 1, the side plate 2, and the top plate is passively driven by the thermal expansion and contraction of a thermal expansion and contraction liquid. Therefore, heat dissipation is stable in use.

Description

technical field [0001] The invention relates to the technical field of petroleum refining, in particular to an automatic instrument for petroleum refining. Background technique [0002] Petroleum is one of the main objects of geological exploration. It is a viscous and dark brown liquid called "industrial blood". There are oil reserves in some areas of the upper crust. The main components are various alkanes, cycloalkanes and aromatics. A mixture of hydrocarbons, the color of crude oil is very rich, including very red, golden yellow, dark green, black and maroon. The color of crude oil is determined by the content of colloid and asphaltene contained in it. The higher the content, the deeper the color. In the process of oil refining, automatic control instruments are usually used to control and display the oil refining. [0003] During the use of automatic instruments in petroleum refining, internal components will generate a lot of heat during use. At this time, it is neces...
