Abstract
The invention provides a solid electric heat accumulation cereal drying oven. The drying oven comprises a heat accumulator, an electric heating element, a thermal insulation tank body, a circulating fan, a closed air circulating passage, a heat exchanger and an insulation base. According to the technical points, the hot-wind heat exchanger is a tube-shell type heat exchanger formed by a tube pass and a shell pass; the tube pass is a hot-wind output passage formed by a connector pipeline component, a heat absorption loop cavity and left and right tube plates; the shell pass is a heat release passage formed by the space which is enclosed by the inside of left and right tube plates and the outer wall of a heat absorption tube; the connector pipeline component comprises an air inlet pipeline, an air guide pipeline and an air outlet pipeline; the heat absorption loop is formed by multiple groups of heat absorption tubes, and each group comprises a plurality of heat absorption tubes which are arranged in matrix; the tube plates are connecting components which are arranged between the connector pipeline component and a heat absorption loop, and are poured and molded by heat-resistance concrete aggregates. By adopting the drying oven, the assembly problem of over size and over weight caused by increasing the heating are of the heat absorption loop to improve the hot-wind output capacity can be solved by virtue of the tube-shell type heat exchanger, and time and labor in the construction process can be reduced by virtue of the tube plates which are constructed by adopting the method of pouring the heat-resistance concrete aggregates.
