Vacuumizing protection system of asphalt reaction kettle with windows

Abstract

The invention relates to a vacuumizing protection system of an asphalt reaction kettle with windows. The vacuumizing protection system is characterized by comprising multiple reaction kettles (1), wherein an observation window (9) is formed in the side wall of each reaction kettle (1) connected with a vacuumizing branch pipe (2), each vacuumizing branch pipe (2) is provided with a check valve (3), the tail end of each vacuumizing branch pipe (2) is connected to a vacuumizing main pipe (4) of which the tail end is connected with a buffer tank (5), the buffer tank (5) is connected with a vacuum pump (6) by a pipeline, and the vacuum pump (6) is connected with a water pool (8) by a water circulation pipeline (7). In the vacuumizing protection system of the asphalt reaction kettle with the windows, air in each reaction kettle is pumped into the water pool and is exhausted to the outside by the vacuum pump, each check valve on the corresponding vacuumizing branch pipe is used for preventing the air along with materials in other reaction kettles from flowing backwards into one reaction kettle, material mixing is prevented, and normal production is ensured.

Description

technical field [0001] The invention relates to a vacuum protection system for an asphalt reactor with a window, which is used for vacuuming the asphalt reactor and can prevent mixing. 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. [00...

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 causes mixing, which affects the normal production, and the previous reaction kettle has no window, and the inside of the mixing tank cannot be seen
