Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

Referring to fig. 1 and 4, the utility model discloses an electric kiln for firing a cup for building, including furnace body 1 and ventilation unit, furnace body 1 adopts the support to support (not shown in the figure), is provided with heat preservation inside liner layer 2 in the furnace body 1, and ventilation unit includes lift translation mechanism, furnace body bottom plate 4 and heat preservation grafting layer 5, and furnace body bottom plate 4, heat preservation grafting layer 5 locate furnace body 1 bottom, and heat preservation grafting layer 5 is fixed mounting on furnace body bottom plate 4, and furnace body 1 bottom is equipped with the rack, and the rack includes many parallel interval arrangement's heat preservation stone brick 3, has ventilation clearance 31; the upper part of the heat preservation inserting layer 5 is provided with a group of bulges 51 which are arranged at intervals, the bulges 51 and the ventilation gap 31 are in a matched step platform shape, and the bulges 51 are clamped with the ventilation gap 31.
