Problems solved by technology

[0004] However, there is a practical problem in the above-mentioned patents. Since the main ingredients furfuryl alcohol and furfural are liquid, it is difficult to rely on the centrifugal force generated by the rotation of the main silo to spray out in the main silo, and the power of the main material injection is insufficient, so it is difficult to It is difficult to form a splash effect. In addition, when the catalyst is added, the countercurrent hedging catalyst will lose power in the later stage of injection, and flow down before the mixed liquid, which leads to a part of the catalyst flowing out without hedging and mixing with the mixed liquid.

Embodiment 1

[0068] like Figure 1 to Figure 13 As shown, a furan resin mixing and proportioning preparation system includes a preparation tank 1 and a driver 2, and also includes:

[0069] The counter mixer 3 is arranged in the preparation tank 1. The counter mixer 3 includes a main material mixing mechanism 31, an auxiliary material diffuser mechanism 32 and a spray mechanism 33, and the main material mixing mechanism 31 is provided in the In the upper part of the preparation tank 1, the main material mixing mechanism 31 is located on the central axis of the preparation tank 1, the auxiliary material diffuser mechanism 32 is arranged around the main material mixing mechanism 31, and the auxiliary material diffuser mechanism 32 is located in the preparation tank. On the side wall of the tank 1, and the auxiliary material flow mechanism 32 outputs auxiliary materials to form a continuous liquid curtain 321, the injection mechanism 33 is arranged below the main material mixing mechanism 31,...

Embodiment 2

[0106] like Figure 14 As shown, a preparation process based on the furan resin mixing and proportioning preparation system of Embodiment 1, comprising:

[0107] Step a, feeding, the main material enters the channel 23 of the main shaft 22 from the main feeding pipe 311 through the inlet 24, and then enters the main material bin 312 from the outlet 25, and the auxiliary material passes through the auxiliary feeding pipe 325 through the feeding port 323 Input into the auxiliary material bin 322, and the catalyst enters the compression bin 411 through the feeding pipeline 412;

[0108] Step b, the main material is stirred and sprayed, the main material entering the main material bin 312 is stirred by the stirring paddle 314 and then input into the material receiving bin 331, and after being sucked by the spray pipe group 332 driven by the rotation of the main shaft 22, it faces the auxiliary material. The direction of the bin 322 is sprayed to form the jet flow of the main mate...

Abstract

The invention relates to the technical field of furan resin preparation and processing, in particular to a furan resin mixing and proportioning preparation system and preparation process, including a preparation tank, an actuator, a counter mixer and a counter, wherein the main material is first adsorbed by using a spray mechanism The main materials of the liquid in the warehouse are furfuryl alcohol and furfural, which are then sprayed and mixed with the liquid curtain formed by the auxiliary materials, namely, the mixed solution of phenol and formaldehyde. Between the layers of auxiliary materials, after the mixed liquid in the state of interlayer is formed, at the lower end of the diffuser plate, the first jet is used for hedging and mixing with the liquid curtain of the mixed liquid in the inclined direction, and the first jet is mixed, relying on the second jet. The liquid curtain impinging on the mixed liquid catches up with the catalyst that does not impinge the mixed liquid curtain, so that the catalyst is mixed evenly.

Description

technical field [0001] The invention relates to the technical field of furan resin preparation and processing, in particular to a furan resin mixing and proportioning preparation system and a preparation process. Background technique [0002] Furan resin refers to the general term of resins produced from furfuryl alcohol and furfural with furan rings as raw materials. It has the advantages of outstanding corrosion resistance, heat resistance, wide source of raw materials and simple production process, which has attracted people's attention. At present, it is widely used in the metallurgical casting industry for modeling, such as the production of many auto parts, plumbing bathrooms, and tire molds. After the furan resin sand process is used for modeling, good economic results are obtained. In the production of furan resin, a mixing device is often used. When using, different raw materials need to be added to the tank according to the proportion, and then mixed by a stirring ...
