Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

An energy-saving zinc oxide kiln shown in figures 1-3 comprises an energy-saving zinc oxide kiln 1, wherein the kiln 1 is composed of a base 2 built by light refractory bricks 14 and a flue 3 arranged at the top of the base 2; the heat preservation layer 5 is embedded in the side wall of the base 2, the heat preservation effect is increased, the heat radiation of the kiln 1 to the outside in the using process can be reduced, so that the indirect fuel saving use is realized, the base 2 is hollow and is provided with the reaction cavity 4, the bottom of the reaction cavity 4 is uniformly provided with a plurality of high-speed burners 6, the input ends of the plurality of high-speed burners 6 are connected in parallel with a gas storage device 8 through a bundling pipe 7, the top layer inside the reaction cavity 4 is provided with a sealing plate 9, the sealing plate 9 divides the inside of the reaction cavity 4 into an upper layer and a lower layer, the temperature of the bottom of the kiln 1 can be rapidly raised, the problem of cold air layering is well avoided, the sealing plate 9 is fixedly connected with the inner wall of the reaction cavity 4 through a strip-shaped connecting plate 10 arranged on the side surface, the top of the sealing plate 9 is provided with a placing groove 12, the top, a ventilation pipe 13 is arranged at the bottom of one side of the kiln 1, and in order to ensure that the air content in the kiln 1 is enough, one end of the ventilation pipe 13 is fixedly connected with an air blower 16.
