A kind of high-efficiency production process of furan resin

Abstract

The invention relates to the field of resin preparation and production, in particular to a furan resin efficient production technology. The furan resin efficient production technology comprises a mainmaterial output part, a preliminary mixing part, a secondary mixing part and a stable flow output part. A main material is conveyed by a mixing part on a main material output assembly and meanwhile ejected by a main material bin under the effect of centrifugal force, a liquid flow layer is divulged through an impact mode, preliminary mixed liquid with the main material and an auxiliary material being of an up-down overlapped structure is formed, impact is conducted through a catalyst which is ejected intermittently in a compressed mode, the main material, the auxiliary material and the catalyst flow down along the surface of a slow flow assembly after being subjected to secondary mixing, and the main material, the auxiliary material and the catalyst are output after penetrating through aflow distributing net; and the main material which is of a spiral structure is output by the mixing part and the liquid flow layer is divulged in an impact mode, the preliminary mixed liquid with themain material and the auxiliary material being overlapped up and down in a spaced mode is formed, then a flow jetting assembly is driven by a preliminary mixing mechanism to conduct secondary mixing on the catalyst in a rotary jetting mode, and the technical problems that the production efficiency is low, and mixing is not even existing in the prior art are solved.

Description

technical field [0001] The invention relates to the field of furan resin production, in particular to a high-efficiency production process of 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, the current mixing production...

Problems solved by technology

[0003] The purpose of the present invention is to provide a high-efficiency furan resin production process aimed at the deficiencies of the prior art. The main material in a spiral structure is output through the mixing part to diverge on the liquid flow layer in an impact manner, forming the upper and lower intervals of the main material and auxiliary materials. The initial mixed liquid, and then the jet component driven by the primary mixing mechanism will carry out the secondary mixing of the catalyst in the form of rotary jetting, so as to solve the technical problems of low production efficiency and uneven mixing in the existing technology
