Convenient-assembly/disassembly vacuumizing protection system of asphalt reaction kettle

Abstract

The invention relates to a convenient-assembly / disassembly vacuumizing protection system of an asphalt reaction kettle. The system is characterized by comprising multiple reaction kettles (1), wherein each reaction kettle (1) is connected with a vacuumizing branch pipe (2); each vacuumizing branch pipe (2) is provided with a check valve (3) and a rubber hose (9); the tail end of each vacuumizing branch pipe (2) is connected with a vacuumizing main pipe (4); the tail end of the vacuumizing main pipe (4) is connected with a buffer tank (5); the buffer tank (5) is connected with a vacuum pump (6) through a pipeline; and the vacuum pump (6) is connected with a pool (8) through a water circulation pipeline (7). In the convenient-assembly / disassembly vacuumizing protection system of an asphalt reaction kettle provided by the invention, the vacuum pump pumps air in each reaction kettle into the pool for outside discharge, and the check valves on the vacuumizing branch pipes can be used for preventing the air together with the materials in other reaction kettles from flowing back into one reaction kettle, thus the material mixing is avoided, and normal production is guaranteed.

Description

technical field [0001] The invention relates to a vacuum protection system for an asphalt reactor which is easy to assemble and disassemble, which is used for vacuuming the asphalt reactor and can prevent mixing of materials. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other i...

Problems solved by technology

However, in the past vacuum system, it was inevitable that the air would be poured into the reactor during vacuuming. Since multiple reactors were vacuumed through the same vacuum pipeline, once the reverse was poured, it would easily cause the materials in one reactor to be mixed into the other. In the reaction kettle, it leads to mixing of materials, which affects the normal production. At the same time, the maintenance of the pipeline of the asphalt reactor in the past is difficult, and the pipeline needs to be disassembled frequently
