Being improved to further of such scheme, this gas sand blender comprises the high-order sand hopper of the taper being arranged at top and the mixture for the mixing of gas sand, the bottom of the high-order sand hopper of this taper is set to sand valve, this mixture is provided with sand input port, air-flow input port and airflow delivery outlet, this sand input port should be communicated with to the output of sand valve, this air-flow input port is connected with the output of air valve, and this airflow delivery outlet is communicated with airflow pipeline.This blender is preferably Venturi tube.
The cyclone separator mentioned in such scheme is commercially available.
The utility model is by arranging the high-order sand hopper and the gas sand blender that bring sand valve at the source place of original flow delivery systems, utilize the source of the gas of original flow delivery systems or source of high pressure air is set separately, by intake valve, source of the gas being connected to the inlet end of gas sand blender.The outlet side of gas sand blender connects into the outlet pipe of original flow delivery systems.At the end of original flow delivery systems, the cyclone separator of changeable connection is set, the dusty gas after parting sand, then enters the bag collection system dirt gas separation one by one of original flow delivery systems.
More specifically, the utility model flue dust airflow pipeline block clearing process comprises the following steps: 1), in high-order sand hopper add sand, or little steel ball or dustless grain slag etc.Open intake valve and to sand valve, after gas, sand mix by proper proportion in gas sand blender, enter original flow delivery systems, block clearing on the way, until the end of original flow delivery systems pipeline at a high speed.2), arrange the cyclone separator of changeable connection at the end of original flow delivery systems pipeline, this cyclone separator output connects the bag collection system of original flow delivery systems, after bag collection, realizes dirt gas and is separated.That is, after entering cyclone separator containing the air-flow of sand, sand is discharged for subsequent use from the bottom of cyclone separator, and air-flow enters the further dedusting of bagroom; 3), according to vapour lock in original airflow pipeline increase state, judge sticky stifled situation in airflow pipeline, regular or irregular startup gas sand blender, utilizes the sand of high-speed motion to remove the flue dust sticked on original airflow pipeline inwall; 4), after block clearing, close sand blender of holding one's breath to sand valve and intake valve, cut off the connection branch road of cyclone separator, recover the normal operation of former flow delivery systems.
The utility model utilizes gas sand blender in airflow pipeline, spray into the sand of high-speed motion, utilizes the washing away of its kinetic energy, cuts, abrasive action block clearing, excellent.Utilize the utility model to airflow pipeline block clearing, high efficient and reliable, simple, solve the historical difficulty that metallurgy industry pneumatic convey easily glues blocked pipeline.
