Rapidly heating distilled kettle

Abstract

The invention discloses a rapidly heating distilled kettle which comprises a kettle body and a coiled pipe, wherein a feeding valve and a discharge valve are arranged at the upper end and the lower end of the kettle body; heating sleeves are arranged at the upper end of the kettle body and the side wall of the kettle body; a vapor tube and a depressurization valve are arranged at the upper end ofthe kettle body; the coiled pipe penetrates through the upper end and the lower end of the kettle body and is guided out respectively; the upper end of the coiled pipe is communicated with the vapor tube; an outlet valve is connected with the lower end of the coiled pipe; two stirring shafts are rotationally connected with the middle section of the kettle body; spiral blades are fixedly connectedwith the middle sections of the stirring shafts; stirring blades are fixedly connected with two sides of the stirring shafts; the left sides of the stirring shafts are rotationally connected with theleft side of the kettle body; and the right sides of the stirring shafts extend outside the kettle body and are in transmission connection with a motor which is fixedly connected with the right side of the kettle body. Due to introduction and reuse of vapor, low-temperature crude oil inside the rapidly heating distilled kettle is secondarily heated through high-temperature vapor, particularly at the primary stage, the crude oil in a middle low-temperature area is rapidly heated through vapor on an outer side, and thus the heating efficiency is improved.

Description

technical field [0001] The invention relates to a still, in particular to a quick-heat still. Background technique [0002] Crude oil needs to be distilled in the production of lubricating oil. At present, the commonly used distillation equipment includes distillation tower and still. The still is a still structure equipped with heating parts and stirring parts. The steam is discharged through the pipe, and the condensation of steam after discharge will release a large amount of heat, which cannot be effectively recycled. In addition, due to the high viscosity of crude oil, the stirring and mixing effect is limited. At present, the heating jacket is installed on the side wall of the kettle, and the external heat is cooled inside. , The initial heating is very uneven. Contents of the invention [0003] The object of the present invention is to provide a kind of rapid heating distillation still, to solve the problem that raises in above-mentioned background technology.
