High-speed segmental reciprocating-type opposite impact mixing head

Abstract

The invention discloses a high-speed segmental reciprocating-type opposite impact mixing head comprising a stirring drum body, a first segment of stirring teeth, a second segment of stirring teeth, a third segment of stirring teeth, a fourth segment of stirring teeth, a fifth segment of stirring teeth, a stirring head connecting shaft, a mixing chamber and a motor, wherein the stirring drum body is cylindrical; the first segment of stirring teeth, the second segment of stirring teeth, the third segment of stirring teeth, the fourth segment of stirring teeth and the fifth segment of stirring teeth are arranged on the outer circumferential surface of the stirring drum body in sequence annularly; the stirring head connecting shaft is connected with the motor; and the mixing chamber is provided with at least one feed pipe and a discharge pipe. According to the high-speed segmental reciprocating-type opposite impact mixing head, reciprocating opposite impact mixing in horizontal and vertical directions can be realized, so as to solve the problems of insufficient mixing during the production process of phenolic resin, eliminate incomplete reaction, greatly reduce the content of free formaldehyde, have high product stability, and greatly improve the toughness, the strength and the like.

Description

technical field [0001] The invention relates to a liquid mixing and stirring device, in particular to a high-speed segmental reciprocating hedging mixing head of a phenolic foam composite material liquid. Background technique [0002] In the traditional liquid mixing and stirring devices used in the production of phenolic foam materials, they are all linear or one-way moving mixing modes, the mixing efficiency is low, it is difficult to mix fully, and the mixing effect is not good. Due to the high viscosity and high density of phenolic resin, if it is not mixed enough, it will directly affect the quality of the product. CN1555926 patent discloses a mixing head of a foaming machine, which is provided with a motor, an impeller, a material mixing chamber and at least one feeding pipe, the impeller shaft is connected to the motor, the impeller is placed in the material mixing chamber, and the feeding pipe is mixed with the material The cavity is connected by an axial feed port,...

AI Technical Summary

Problems solved by technology

[0003] The technical problem mainly solved by the present invention is to provide a high-speed segmental reciprocating hedging mixing head, so that the combined feed liquid of the phenolic foam can be reciprocated and mixed in the horizontal and vertical directions through the mixing device in the high-speed segmental mode, solving the problem of The problem of insufficient mixing of phenolic resin in the production process solves the problem of incomplete reaction at the same time. It can also adjust the rise time and curing time, and greatly reduce the content of free aldehydes. The product has good stability, toughness, and strength. greatly improved
