Problems solved by technology

[0003] The problems in the above technical solution are: the fastening ring is made of metal material, and the expansion coefficient of the firebrick itself is inconsistent with that of the refractory brick material. The expansion of the refractory brick on the outer ring will squeeze the fastening ring and be damaged, resulting in insufficient stability of the furnace roof structure. security risks

Abstract

The invention discloses a furnace cover structure of a kiln. The furnace cover structure comprises a furnace top frame, a bottom frame and a top frame, wherein a furnace top is arranged in an area defined by the furnace top frame, the furnace top frame is defined by a plurality of peripheral pipe bodies, a gap is reserved between the ends of any two adjacent peripheral pipe bodies, the bottom frame surrounds the outer side of the furnace top frame, a plurality of elastic supporting devices are arranged in an area between the bottom frame and the furnace top frame, a plurality of pressing plates are arranged above the bottom frame, one ends of the pressing plates are fixed to the bottom frame, the other ends of the pressing plates abut against the furnace top frame, the top frame is located above the bottom frame, the top frame is connected with the bottom frame through a plurality of supporting columns, a hanging frame is arranged in an area defined by the top frame, the furnace top is connected with the hanging frame through a plurality of steel wires, and each peripheral pipe body is connected with the hanging frame through a plurality of pulling pieces. According to the invention, the furnace top frame can move towards the periphery along with heating expansion of the furnace top, the furnace top cannot be damaged due to extrusion, and the whole furnace top is stable in performance and more reliable in structure.

Description

technical field [0001] The invention relates to the field of firing special ceramics, in particular to a kiln cover structure. Background technique [0002] The roof of the existing well-type kiln is usually designed as an openable structure. By opening the furnace cover, firing parts can be added to or taken out of the furnace. The furnace cover is usually opened and closed by crane. The furnace cover structure mainly includes a fastening ring, and a furnace roof composed of refractory bricks is arranged in the area enclosed by the fastening ring, and the refractory bricks are bonded together by high-temperature-resistant refractory mud. [0003] The problems in the above technical solution are: the fastening ring is made of metal material, and the expansion coefficient of the firebrick itself is inconsistent with that of the refractory brick material. The expansion of the refractory brick on the outer ring will squeeze the fastening ring and be damaged, resulting in insuff...
