Energy saving thermal-insulation cross wall of carbon roasting furnace

Abstract

The invention discloses an energy saving thermal insulation cross wall of a carbon roasting furnace, and is divided into a plurality of layers and is formed by building fire-resistant concrete precastblocks. Adjacent fire-resistant concrete precast blocks are spliced and fixed through refractory mortar; joints of the fire-resistant concrete precast blocks between adjacent layers in a vertical direction are not coaxial; the fire-resistant concrete precast blocks are all of a hollow structure and are divided into four types, including a fixing block, a flame path wall connecting block, a material distribution chamber connecting block and a fire well block; the fire well block is positioned on the top end of a whole wall body and is provided with a fire through hole; the fire through hole penetrates through a fire wall brick; the hollow structure of the fixing block and the hollow structure of the material distribution chamber connecting block communicate in a vertical direction to forma cavity; and the inner wall of the cavity is provided with a light thermal-insulation material. The energy saving thermal insulation cross wall has a stable structure, and the fire-resistant concreteprecast blocks are adopted to replace traditional clay bricks. In addition, the hollow structure is arranged, the light thermal-insulation material is arranged in the hollow structure, so that the heat protection and thermal insulation performance of the cross wall can be increased to a large extent, heat loss is reduced, energy is saved, and in addition, production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of carbon roasting furnaces, in particular to an energy-saving and heat-preserving horizontal wall of a carbon roasting furnace. Background technique [0002] The roasting furnace is one of the main production equipment in the aluminum carbon anode production line, which plays an important role in the production. The anode can achieve the necessary quality characteristics through roasting. The structure of the roasting furnace and the control of the roasting process directly affect the quality of the roasted product; At present, most manufacturers in my country use open-type annular roasters. With the increase of scale and production capacity, how to achieve energy saving and consumption reduction and constant quality has become a common goal; The walls are all made of small clay bricks. The production of clay bricks requires high-temperature firing, and the masonry process is also slow. It is easy to deform u...

[0002] The roasting furnace is one of the main production equipment in the aluminum carbon anode production line, which plays an important role in the production. The anode can achieve the necessary quality characteristics through roasting. The structure of the roasting furnace and the control of the roasting process directly affect the quality of the roasted product; At present, most manufacturers in my country use open-type annular roasters. With the increase of scale and production capacity, how to achieve energy saving and consumption reduction and constant quality has become a common goal; The walls are all made of small clay bricks. The production of clay bricks requires high-temperature firing, and the masonry process is also slow. It is easy to deform under the long-term high-temperature working condition of the carbon roaster, which is no longer suitable for large-scale and large-capacity carbon. Used in roasting furnace
