Abstract

The invention relates to a heat preservation device used for firing of earthenware and a use method of the heat preservation device, and belongs to the technical field of heat preservation devices used for firing of the earthenware. The heat preservation device and the use method mainly solve the technical problems that an existing heat preservation device is likely to crack, low in production efficiency and high in labor intensity. According to the technical scheme, the heat preservation device used for firing of the earthenware comprises a heat preservation cover composed of a shell, a heat preservation layer and a hoisting component, wherein the heat preservation device further comprises multiple fork tools, fork tool connection plates, hooks and lifting lugs; and multiple mud fixing jaws are evenly arranged on the inner wall of the shell, the heat preservation layer is arranged on the inner wall of the shell and is fixed through the mud fixing jaws, the lifting lugs are symmetrically arranged on the lower portions of the outer walls on the two sides of the shell, the hoisting component is arranged on the top of the shell, the fork tools are arranged below the heat preservation cover, and multiple through holes are formed in the fork tool connection plates. The method for using the heat preservation device used for firing of the earthenware includes the first step of earthenware firing, the second step of fork tool placement and the third step of slow cooling.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation equipment for firing sand products, and in particular relates to a thermal insulation device for firing sand products and a method for using the same. Background technique [0002] Heat preservation during firing of sand and cooling after firing are essential processes. The sand that has just been fired must be kept warm to eliminate stress and reduce cracks, so as to achieve slow cooling of the sand and avoid damage caused by rapid cooling. The sand cargo produces cracks and becomes a waste product. However, the existing thermal insulation cover is purely made of black gangue, and the working environment expands with heat and contracts with cold. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, provide a thermal insulation device for sand cargo firing and its use method, and solve the technical problems of eas...
