Abstract
The utility model relates to a control device for an air supply system of a metallurgical blast furnace, particularly a bidirectional automatic wind distributing device for blast main pipes of blast furnaces with multiple seats. A connection main pipe (9) is installed between the blast main pipes of each blast furnace. A motorized valve (10) and a pneumatic valve (11) are arranged on the connection main pipe (9). A programmable controller (12) which is arranged controls the states of the pneumatic valve. The motorized valve is provided with a definite angle under the normal condition, and the pneumatic valve can be closed. When accidents occur, the programmable controller controls the pneumatic valve to open rapidly and in time. The bidirectional wind distributing performance between main pipes can be realized. The utility model has the advantages of reasonable structure, automatic bidirectional wind distributing performance, slag filling prevention of blast furnace tuyere, etc.
Description
The utility model relates to a kind of metallurgy high furnace supply air system control device, particularly many two-way automatic wind turning devices of the female pipe of blast furnace air feed.
At present; people carry out the piping-main scheme air-supply to many metallurgy high furnace air feeds; each not contact between female pipe of blowing; in case disconnected wind accident such as shutdown or removal of load suddenly takes place in certain unit; the production of its institute's air feed blast furnace will be had a strong impact on; even cause blast-furnace tuyere pour slag, cause utmost point bad influence for the ordinary production of blast furnace.
The utility model purpose provides the two-way automatic wind turning device of the female pipe of a kind of blast furnace air feed, and many blast furnace air feed buses are organically connected, and solves the problems referred to above that prior art exists.
The technical solution of the utility model is: the female pipe of contact is installed between the female pipe of the air-supply of each blast furnace, motorized valve and pneumavalve are installed on this female pipe, the programmable controller controls pneumavalve is set.
Adopt the utility model, electrically operated valve is opened certain angle under the normal circumstances, and operated pneumatic valve is closed, and when accident occurring, the programmable controller controls pneumavalve rapidly, in time open is realized two-way wind turning between female pipe, prevents the blast-furnace tuyere pour slag accident.
The utlity model has rational in infrastructure, automatic bidirectional wind turning, prevent characteristics such as blast-furnace tuyere pour slag.
Accompanying drawing is the utility model example structure synoptic diagram.
Below in conjunction with accompanying drawing, further specify the utility model by example.
In an embodiment, the utility model is applied to two blast furnaces (1,2), three typhoon machines (3,4,5) air feed system, article two, female pipe (7,8) is respectively to two blast furnace air feeds, article two, a female pipe of contact (9) is installed between female pipe, on the female pipe of contact (9) motorized valve (10) and pneumavalve (1) are set, programmable controller (12) control pneumavalve state is set.Under the normal circumstances, electrically operated valve is opened certain angle, (control wind turning amount size), operated pneumatic valve is closed, and two female pipes are normally blown to two blast furnaces respectively, when accident occurring, detection system is sent signal into programmable controller (2), the programmable controller controls pneumavalve is opened rapidly, realizes two-way wind turning between two female pipes, prevents the blast-furnace tuyere pour slag accident.
Claims (1)
1, the two-way automatic wind turning device of the female pipe of a kind of blast furnace air feed, it is characterized in that installing between each blast furnace air feed pipe a female pipe of contact (9), on the female pipe of contact (9) motorized valve (10) and pneumavalve (11) are set, programmable controller (12) control pneumavalve state is set.
