Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in figure 1, a carborundum miropowder stoving recovery unit, including stoving storehouse 1, stoving storehouse 1 bottom intercommunication has hot-blast emergence mechanism, and the lateral wall intercommunication has feed mechanism, and the top intercommunication has recovery mechanism. The hot air generating mechanism comprises a hot air blower 2, an air inlet of the hot air blower 2 is communicated with an air filter 3, and an air outlet of the hot air blower 2 is communicated with the bottom of the drying bin 1 through a pipeline. The feeding mechanism comprises a feeding pipe 4 communicated with the side wall of the drying bin 1, a feeding auger 5 extending into the inner cavity of the drying bin 1 is arranged inside the feeding pipe 4, and the other end of the feeding auger 5 is connected with a feeding motor 6. The top of the feeding pipe 4 is communicated with an inverted circular truncated cone type feeding cylinder 7. The recycling mechanism comprises a slow release bin 8 communicated with the drying bin 1 through a pipeline, the top of the slow release bin 8 is covered with a breathable micro powder filtering membrane 12, the bottom of the slow release bin 8 is of an inverted cone shape, a vibrating block 13 is fixed on an outer inclined plane of an inverted cone, an opening at the bottom of the slow release bin 8 is arranged at the tip of the inverted cone, and the opening at the bottom is smaller than an opening at the top of the slow release bin 8; an electric sieve 9 is arranged under the opening at the bottom of the slow release bin 8, and a material forming bin 10 is arranged under the electric sieve 9.
