Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provides a kind of simple in structure, with low cost, effectively carries out the cleaning of blast furnace stack blow valve port, prevents from stopping up the blast furnace stack static pressure measurement antiplugging apparatus of stable and reliable operation.
The utility model solves the technical scheme that its technical problem adopts:
Blast furnace stack static pressure measurement antiplugging apparatus, it is characterized in that, include the Prefabricated fireproof brick being arranged in blast furnace furnace wall, in Prefabricated fireproof brick, have the clear opening of an inclination, the inner of clear opening has the bell of horn shape, and outer end is communicated with blowback extension tube, and blowback extension tube extends outward blast furnace furnace wall, and being communicated with pressure outer tube, pressure outer tube is communicated with source purge gas and logical apparatus for ash simultaneously; Wherein said logical apparatus for ash is arranged on pressure outer tube top, includes push rod and cylinder, and its push rod is arranged in pressure outer tube, and can push in blowback extension tube.
In such scheme, described blowback extension tube is embedded in blast furnace furnace wall, and with clear opening be same axis, the internal diameter of blowback extension tube is identical with the pore size of clear opening, the end of blowback extension tube is external thread structure.
In such scheme, the connecting portion of described clear opening and blowback extension tube is also provided with steel plate, and steel plate surrounds Prefabricated fireproof brick, and has identical with blowback extension tube external diameter size, and the internal thread hole concentric with clear opening, blowback extension tube is screwed and is connected by screw thread with steel plate.
In such scheme, described source purge gas includes pressure switch, pressure pipe, pressure measuring valve, connecting pipe successively, and connecting pipe is communicated with Pneumatic controller.
In such scheme, described Pneumatic controller includes many groups monomer in parallel, and every group of monomer includes pressure unit, vacuum breaker, magnetic valve, permanent flow valve successively; Described Pneumatic controller is connected with direct-operated regulator and filtering pressure reducing valve in turn.
In such scheme, described source purge gas and logical apparatus for ash are all communicated with computer, by its valve of computer control.
The feature of this antiplugging apparatus is the mode of extension tube that adds by blow valve port Prefabricated fireproof brick, Prefabricated fireproof brick stove inner opening is partly taper, the other end is that screw thread is connected with extension tube, additional automatically logical apparatus for ash, by computer control source purge gas and automatically logical apparatus for ash, by constant current, purge pressure port simultaneously and make it not stifled; Permanent flow valve on source purge gas, can keep constant current output after flow set; Normal circumstances constant pressure within the specific limits, when the height report limit value of pressure overpressure switch, magnetic valve action, the gas in cylinder promotes piston and does stretching motion one time together with push rod, and blowback extension tube is dredged.
Technical superiority of the present utility model is:
The utility model is simple in structure, with low cost, can effectively carry out the cleaning of blast furnace stack blow valve port, prevents from stopping up stable and reliable operation.
