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

Embodiment 1

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0038] Refer to the attached figure 1 A high-efficiency production process of furan resin in Example 1 of the present invention is described.

[0039] A kind of high-efficiency production technique of furan resin, comprises the following steps:

[0040] (a) the main material output part, the main material is sprayed out through the spray hole 3113 through the main material bin with the rotating centrifugal force while being transported in a rotating manner through the mixing part 311 on the main material output assembly 31;

[...

Embodiment 2

[0049] Wherein, the same or corresponding parts as those in the first embodiment adopt the reference numerals corresponding to the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below; the difference between the second embodiment and the first embodiment is that : the jet hole 3113 is set in a spiral structure, the main material is sprayed out through the jet hole 3113 to form a main material layer spaced up and down, and the auxiliary material after diverging and splashing through the groove 3251 is between the main material layers.

[0050] Further, the step (c) includes the catalyst output part, the spray flow assembly 41 is connected with the main bin 312 in a synchronous rotation manner, and the roller 417 arranged on the mixing chamber 1 and the top protrusion at the bottom of the spray flow assembly 41 The table 416 is driven in a guiding transmission mode to realize the upward movement of the storage part 411 i...

Embodiment 3

[0058] Reference attached Figure 2-10 A spiral multi-component mixing production device in Example 3 of the present invention is described.

[0059] like figure 2 , 3 , 4, 5, 6, 7 and 8, a spiral multi-component mixing production device includes a mixing chamber 1 and a driving mechanism 2, and also includes:

[0060] Preliminary mixing mechanism 3, described preliminary mixing mechanism 3 is arranged in the described mixing chamber 1, and it comprises main material output assembly 31 and auxiliary material mixing assembly 32, and the main material in main material output assembly 31 is mixed by being arranged on it After the output is driven by the part 311, it is ejected in a spiral structure; the auxiliary material in the auxiliary material mixing assembly 32 flows continuously through the flow port 321 arranged on it, and forms a liquid flow layer 322 below it; in this embodiment, the flow layer 322 The mouth 321 is provided with an annular mouth continuously, and the...

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...
