Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0024] Such as figure 1 As shown, this embodiment provides a phenolic resin stirring device including a tank body 1 and a feed pipe 2 , wherein a main shaft 3 is arranged at the centerline of the tank body 1 . One end of the main shaft 3 is rotatably connected with the end cover 4 of the tank body 1, and the other end is rotatably connected with the support frame 5 arranged at the bottom of the tank body 1. The bottom and the middle of the main shaft 3 are provided with a stirring impeller 6, which is connected with the main shaft 3 The driving motor drives the main shaft 3 and the stirring impeller 6 arranged on the main shaft 3 to rotate, so that the materials participating in the reaction in the tank body 1 can be stirred. At the same time, since the middle and bottom of the main shaft 1 are equ...

Abstract

The invention relates to the technical field of stirring devices, in particular to a phenolic resin stirring tank. The phenolic resin stirring tank comprises a tank body and a feeding pipe. A main shaft is arranged in the position of the center line of the tank body. One end of the main shaft is connected with an end cap of the tank body in a rotatable mode and the other end of the main shaft is connected with a support arranged at the bottom of the tank body in a rotatable mode. Stirring impellers are arranged in the middle of the main shaft and at the bottom of the main shaft respectively and a heating device is further arranged outside the tank body. According to the phenolic resin stirring tank, the stirring impellers are arranged in the middle of the main shaft and at the bottom of the main shaft respectively and can more sufficiently stir materials involved in a reaction and placed in the stirring tank. In addition, the heating device is arranged outside the tank body, so that the stirring tank has the better heat preservation performance.

Description

technical field [0001] The invention relates to the technical field of stirring devices, in particular to a phenolic resin stirring tank. Background technique [0002] Phenolic resin is also called bakelite, also known as bakelite powder. Originally a colorless or yellowish-brown transparent substance, the market often adds coloring agents to turn it into red, yellow, black, green, brown, blue and other colors, with granules and powders. Resistant to weak acid and weak alkali, it will decompose in case of strong acid and corrode in case of strong alkali. Insoluble in water, soluble in acetone, alcohol and other organic solvents. Phenolic resin is mainly used in the manufacture of various plastics, coatings, adhesives and synthetic fibers. [0003] Commonly used raw materials for phenolic resins are phenol, resorcinol, m-cresol, xylenol, p-tert-butyl or p-phenylphenol, formaldehyde, furfural, etc. The production process includes two steps of polycondensation and dehydrati...
