Vacuum pumping protection system of asphalt reaction kettles with transport chassis

Abstract

The invention relates to a vacuum pumping protection system of asphalt reaction kettles with transport chassis. The vacuum pumping protection system comprises a plurality of reaction kettles (1), the bottom of every reaction kettle (1) is provided with a transport chassis (10), every reaction kettle (1) is connected with a vacuum pumping branch tube (2), every vacuum pumping branch tube (2) is provided with a check valve (3), the tail end of every vacuum pumping branch tube (2) is connected to a vacuum pumping main tube (4), the tail end of the vacuum pumping main tube (4) is connected with a buffering tank (5), the buffering tank (5) is connected with a vacuum pump (6) through a pipeline, and the vacuum pump (6) is connected with a water pool (8) through a water circulation pipeline (7). The vacuum pumping protection system of asphalt reaction kettles with transport chassis pumps air in every reaction kettle to the water pool through the vacuum pump and then discharges obtained water to the outside; and the check valves on the vacuum pumping branch tubes are used for preventing air poured into one of the reaction kettles from carrying materials in other reaction kettles in order to prevent material mixing, so normal production is guaranteed.

Description

technical field [0001] The invention relates to a vacuum protection system for an asphalt reactor with a transport chassis, which is used for vacuuming the asphalt reactor and preventing 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 roa...

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, which affects the normal production, and the previous reaction kettle cannot be moved, which is inconvenient to use
