Vacuuming protection system of asphalt reaction kettle

Abstract

The invention relates to a vacuuming protection system of an asphalt reaction kettle. The vacuuming protection system is characterized by comprising a plurality of reaction kettles (1), wherein each reaction kettle (1) is connected with a vacuuming branch tube (2); a check valve (3) is arranged on each vacuuming branch tube (2); the tail end of each vacuuming branch tube (2) is connected with a vacuuming main tube (4); the tail end of the vacuuming main tube (4) is connected with a buffer tank (5); the buffer tank (5) is connected with a vacuum pump (6) through a pipeline; the vacuum pump (6) is connected with a pool (8) through a water circulation pipeline (7). By adopting the vacuuming protection system of the asphalt reaction kettle, air inside each reaction kettle can be pumped into the pool through the vacuum pump and is discharged outside, and due to adoption of the check valves on the vacuuming branch tubes, the situation that materials in other reaction kettles flow back into one reaction kettle together with air can be avoided, so that material mixing can be prevented, and normal production can be ensured.

Description

technical field [0001] The invention relates to a vacuum protection system for an asphalt reactor, which is used for vacuuming the asphalt reactor and preventing 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 industries as well as paving roads. [0003...

AI Technical Summary

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 reactor, it causes mixing, which affects the normal production
