Embodiment 1

[0035] 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.

[0036] The fixed-ratio production process of thermosetting furan resin comprises the following steps:

[0037] (a) The mixing part of the main and auxiliary materials. The main material is output in a rotating and centrifugal manner through the main material output assembly 31, and the auxiliary material is sprayed out in a pressurized manner through the auxiliary material feeding assembly 32. form an initial mixture;

[0038] (b) Catalyst mixing part, the initial mixed liquid formed by step (a) enters the catalyst adding statio...

Embodiment 2

[0046] 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 step (c) includes breaking up the mixing part, and the agitating assembly 43 rotates while driving a plurality of collecting plates 431 on it to rotate, and the preliminary mixed liquid falling in sequence is broken up by the collecting plate 431 and then distributed to the agitating assembly The surface of 43 is mixed by the rotating centrifugal force of the stirring assembly 43; the preliminary mixed liquid in the falling process is impacted by the movement of the rotating collecting plate 431, and the initial mixing is carried out by the stirring assembly 43 while it is splashing. The position of the liquid is transferred to realize the dispersion and ...

Embodiment 3

[0052] Reference attached Figure 2-9 A multi-component furan resin mixing production machine in Example 3 of the present invention is described.

[0053] Such as figure 2 , 3 , 4 and 5, a multi-component furan resin mixing production machine, including a mixing chamber 1 and a power mechanism 2, also includes:

[0054] Mixing mechanism 3, the mixing mechanism 3 is arranged in the inside of the mixing bin 1, it includes a main material output assembly 31 and an auxiliary material feeding assembly 32, the main material output assembly 31 includes a main material buffer bin 313, arranged in the The multiple pressurizing parts 311 on the main material buffer bin 313 and the stirring and diverging parts 312 respectively arranged on one side of the pressurizing parts 311, the main ingredients in the main material buffer bin 313 are arranged through the multiple pressurizing parts evenly distributed. After 311 is partially pressurized, it is initially stirred and mixed by the st...

Abstract

The invention relates to a thermocuring furan resin constant proportion production process. The thermocuring furan resin constant proportion production process comprises a main material and auxiliarymaterial mixing part, a catalyst mixing part, a secondary mixing part and an output part. Main materials are output through a main material output assembly, auxiliary materials are sprayed out throughan auxiliary material feeding assembly in a pressurizing manner, and after the main materials and the auxiliary materials make contact with one another and mixed in an up-down overlaying mixing manner, in the falling process of primarily-mixed liquid, a catalyst sprayed out in a compressing manner through a stirring mechanism scatters the falling primarily-mixed liquid in a spraying manner in thehorizontal direction and is mixed with the primarily-mixed liquid; in the process that the primarily-mixed liquid falls onto a stirring assembly, the primarily-mixed liquid is received by the stirring assembly and is gathered by the stirring assembly in an oblique plate guiding manner, and then the primarily-mixed liquid is output through a discharging port; and after mixing of the discontinuously quantified main materials and auxiliary materials, the quantified catalyst impacts, scatters and mixes the main material and auxiliary material mixed liquid, uniform mixing of the main materials, the auxiliary materials and the catalyst is achieved, and the technical problems that in the prior art, mixing is not uniform, and matching is rough are solved.

Description

technical field [0001] The invention relates to the field of resin synthesis production, in particular to a fixed-ratio production process of heat-cured 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...
