Firing method of grey-section purple grit mud and furnace kiln using same

The invention discloses a firing method for purple grit mud in a green grey section and a kiln using the method. A basic firing mechanism comprises a stable bottom plate, the top of the stable bottom plate is fixedly connected with an electric kiln through a fixing plate, the rear side of the top of the stable bottom plate is fixedly connected with a cylinder, and the top end of the cylinder is fixedly connected with an upper pressing plate; a sliding pressing column is slidably mounted on the front side of the top of the upper pressing plate by forming an opening. The basic firing mechanism and the feeding and discharging mounting mechanisms are used in a combined mode, the feeding and discharging mounting mechanisms on the two sides can be alternately in butt joint with the basic firing mechanism, the firing process is continuously completed, and the firing efficiency is improved; in addition, butt joint and separation of the feeding and discharging mounting mechanism and the basic firing mechanism can be c
