Feeding end seal

Abstract

The invention discloses a feeding end seal. The feeding end seal comprises a first connecting plate. A corrugated pipe fixedly communicates with the right side of the first connecting plate. A connecting pipe is arranged on the right side of the corrugated pipe. The left end of the connecting pipe penetrates into an inner cavity of the corrugated pipe. A second connecting plate communicates with the right side of the connecting pipe. A sealing ring and a sealing loop are sequentially arranged on the surface of the connecting pipe from right to left in a sleeving mode. A fixing ring is arranged on the surface of the sealing loop in a sleeving mode. The right side of the fixing ring is fixedly connected with the sealing ring. The right end of the corrugated pipe is located in an inner cavity of the sealing loop. By arranging the first connecting plate, the corrugated pipe, the sealing loop, the sealing ring, the connecting pipe, the second connecting plate, a second through hole, the fixing ring, a graphite wire rod and a first through for cooperation application, the problem that the sealing effect between a rotary furnace connector and a feeding inlet is poor at present is solved, the feeding end seal has the advantage of good sealing effect, usage of users is facilitated, and the feeding end seal is worthy of popularizing.

Description

technical field [0001] The invention relates to the technical field of rotary kilns, in particular to the sealing of feed ends. Background technique [0002] Rotary furnace is a kind of thermal equipment for calcining, roasting or drying granular and powdery materials. The furnace body of the rotary furnace is a long steel cylinder lined with refractory materials. The furnace body is supported on several pairs of supporting wheels, and With an inclination of 3% to 6%, the furnace body rotates slowly through the gear driven by the motor. The material is added from the higher end and discharged from the lower end of the furnace. The fuel coal powder, heavy oil or fuel is injected into the furnace end. Gas fuel is burned in the furnace, and the flue gas is discharged from the higher end to flow countercurrently with the flue gas. It is mainly used for calcining cement clinker in the cement industry, and is also used for calcining granular and powdery materials in the refractory...
