Aerogenerator of triethylamine

Abstract

The invention provides a triethylamine gas generator, comprising a carburetor and an enclosed quantitative amine adding device; the carburetor comprises a heat accumulation body, a heating pipe and a vaporization pipe; the heating pipe and the vaporization pipe are arranged inside the heat accumulation body; the vaporization pipe is distributed in a snake shape in a circuitous way; the heating pipes are arranged between the gaps of the vaporization pipe at intervals; the vaporization pipe is provided with an amine adding mouth, a vaporization amine outlet and a gas inlet; the enclosed quantitative amine adding device is connected with the amine adding mouth of the carburetor. The carburetor of the invention has enough heat source, heat accumulation quantity and good heat exchange conditions, therefore, the flowing liquid amine can be ensured to be sufficiently vaporized, the hardening speed of the sand core can be effectively improved, the amine consumption can be reduced, the environmental pollution can be controlled radically, the production efficiency and the sand core quality can be improved; meanwhile, the enclosed quantitative amine adding device is an enclosed system, therefore, the control is simple and convenient, the quantification is exact, as well as the device is separated from the atmosphere and has no volatilization pollution.

Description

technical field [0001] The invention relates to a triethylamine gas generator matched with a cold box core shooter, and belongs to the technical field of triethylamine gas generators in foundry machinery. Background technique [0002] In the whole process of casting production, some important castings have high requirements on sand cores. Sand cores must not only have sufficient strength, accurate size, and clear outline, but also have good collapsibility. The equipment required for the entire core-making process includes a sand mixer, a core shooter, and a triethylamine gas generator matched with the core shooter. The performance of these equipment is directly related to the production quality and efficiency of sand cores. The function of the triethylamine gas generator is to make the liquid amine into gaseous amine and enter the core box through the blowing mechanism to harden the sand core. At present, the problems of triethylamine gas generators are: poor vaporization o...
