Abstract

The invention discloses a roller kiln and spray tower negative pressure exhaust pipeline emergency emptying mechanics mechanism which comprises a waste heat main pipeline. The roller kiln and spray tower negative pressure exhaust pipeline emergency emptying mechanics mechanism is characterized in that a transit draught fan is arranged on the waste heat main pipeline, and the smoke flowing direction of the transit draught fan is the same as the smoke flowing direction of the waste heat main pipeline; the mechanics mechanism further comprises a conical pipeline, the two ends of the conical pipeline are connected with the waste heat main pipeline, and in the smoke flowing direction, the inlet end of the conical pipeline shrinks and the outlet end of the conical pipeline expands; a plurality of emptying small pipes are arranged on the outlet end face of the conical pipeline, and the outlet ends of the emptying small pipes are provided with movable cover plates. The transit draught fan pumps hot smoke of the waste heat main pipeline into an air distribution opening of a water-coal slurry boiler matched with a spray tower for air distribution, the movable cover plates of the emptying small pipes are automatically opened when the pressure in the waste heat main pipeline suddenly decreases, and the stable working of a roller kiln and spray tower breathing system is ensured through the transit draught fan and the emptying small pipes together.

Description

technical field [0001] The invention relates to the field of manufacturing equipment for ceramic building decoration materials, in particular to a mechanical mechanism for emergency emptying of a negative pressure exhaust air duct in a roller kiln-spray drying tower waste heat utilization breathing system. Background technique [0002] In the debugging of the common roller kiln-spray tower waste heat utilization breathing system, it is found that when the electric valve of the exhaust fan exhaust pipe of the roller kiln fails to start or is opened due to a fault, the pressure in the main pipe of waste heat utilization may increase. Turning to positive pressure will lead to operational risks to the system, affect the normal work of the roller kiln and spray tower, and cause abnormal operation of the entire respiratory system. Contents of the invention [0003] The problem to be solved by the present invention is: when the sluice plate of the exhaust pipe of the exhaust fan ...
