Abstract

The invention relates to the technical field of chemical industry production, in particular to a thermosetting furan resin definite-proportion production system and process. The thermosetting furan resin definite-proportion production system comprises a power mechanism, a caching mechanism and an output mechanism, wherein the caching mechanism comprises a main material cashing cabin and an auxiliary material temporary storage and mixing space; in the working process, the power mechanism drives a compression component to move and also drives a barrier component and a catalyst output component to move, a main material and an auxiliary material flow out respectively by virtue of an output part and aguide-inpart arranged on the auxiliary material temporary storage cabin, liquid flow columns which are opposite to each other and are staggered from each other are respectively formed in the mixing space, and a mixed solution contacts and is mixed with a catalyst outputted from the catalyst output component in the falling process; and when the auxiliary material is indirectly and quantitatively outputted by virtue of the compression component, the barrier component and the catalyst output component are driven to mix the main material and the auxiliary material to be mixed with the catalyst in a definite proportion, so that the problems in the prior art that the raw materials are incorrect in proportion and non-uniform in mixing can be solved.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a fixed-ratio production system and process for heat-curing furan resin. Background technique [0002] Furan resin refers to the general name of resins produced from furfuryl alcohol and furfural with furan ring as raw materials. It has outstanding corrosion resistance, heat resistance, wide source of raw materials, simple production process and other advantages, which has attracted people's attention. At present, it is widely used in the metallurgical casting industry for molding. For example, in the production of many auto parts, plumbing and sanitary ware, and tire molds, good economic results can be obtained after using furan resin sand for molding. The production of furan resin often requires the use of a mixing device. When using it, different raw materials need to be added to the tank according to the proportion, and then mixed by a stirring device. However, th...
