Cooling device for preparing nano zinc oxide

Abstract

The invention relates to the technical field of zinc oxide production and processing, and discloses a cooling device for preparing nano zinc oxide. The cooling device comprises a cooling box, whereina servo motor is fixedly installed at the top of the cooling box, a rotating rod is fixedly connected to the output end of the servo motor, a spiral pipe is arranged in a cavity of the cooling box, and linkage devices which are sequentially distributed in an array mode from top to bottom are arranged on the inner wall of the cooling box. According to the cooling device for preparing the nano zincoxide, the rotating rod and fan plates are arranged, the rotating fan plates stir cooling liquid in the cavity of the cooling box, the cooling liquid located in the spiral center of the spiral pipe isstirred, the cooling efficiency of the nano zinc oxide is improved, and the problems that the cooling liquid at the center position of the spiral pipe is heated by the nano zinc oxide, so that the cooling liquid is heated and does not circulate, and the cooling efficiency is reduced are solved; and through continuous stirring of the fan plates, the cooling efficiency of the nano zinc oxide is improved, the circulation and heat exchange efficiency of the cooling liquid in the cavity of the cooling box is improved, and the cooling device has high practicability.

Description

technical field [0001] The invention relates to the technical field of zinc oxide production and processing, in particular to a cooling device for preparing nano zinc oxide. Background technique [0002] As we all know, the nano-zinc oxide preparation device is an auxiliary device used in the preparation process of nano-zinc oxide to cool the material and make the material better packaged. It has been widely used in the field of nano-zinc oxide preparation. [0003] The existing nano-zinc oxide cooling device includes a flow pipe and a work box. The flow pipe passes through the work box filled with cooling liquid, and the nanometer is injected into the flow pipe and passes through the work box to cool. The existing technical design is simple, and the nano-zinc oxide Circulation is carried out in the flow pipe in the spiral state, and cooling is carried out in the work box. Because the temperature of the nano-zinc oxide that has just passed through the flow pipe is high, the ...

[0003] The existing nano-zinc oxide cooling device includes a flow pipe and a work box. The flow pipe passes through the work box filled with cooling liquid, and the nanometer is injected into the flow pipe and passes through the work box to cool. The existing technical design is simple, and the nano-zinc oxide Circulate in the flow pipe in the spiral state, and cool in the work box. Because the temperature of the nano-zinc oxide that has just passed through the flow pipe is high, the temperature of the coolant above the work box cavity is often high, and the temperature angle of the bottom is second. The temperature of the coolant around the flow tube in the spiral state and in the center of the spiral is also generally high, which will lead to the problem of low cooling efficiency of nano-zinc oxide
