Abstract
The utility model provides a front energy-saving hydraulic system of a blast furnace. An electronic pump is composed of an open pump, a proportional valve, a swing angle sensor and an electronic controller. A programmable controller outputs ideal value of flow to the electronic controller according to different acting equipment, the swing angle sensor feeds back actual value of output flow of the open pump to the electronic controller, the electronic controller compares and computes the ideal value with the actual value and then outputs results to the proportional valve, and the proportional valve is used for adjusting the output flow of the pump until the actual value reaches the ideal value. The front energy-saving hydraulic system controls the flow effectively, saves energy, decreases the number of components and saves cost as a mud gun and a tapping machine share a hydraulic system, is simple in control and convenient in operation, omits a reducing valve and benefits environmental protection.
Description
Technical field
The utility model relates to the preceding hydraulic efficiency system of a kind of State of Blast Furnace.
Background technology
The stokehold system is the indispensable part of blast furnace.Will regularly tap a blast furnace during blast furnace ironmaking, finish and blast furnace taphole will be blocked after tapping a blast furnace, Hydraulic clay gun is the specific equipment of envelope stifled iron notch, and iron perforater is a specific equipment of beating tapping outlet.Along with furnace volume more and more is tending towards maximizing, clay gun and taphole drilling machine all adopt the mode of full hydraulic drive.But hydraulic efficiency system need provide high-pressure high-flow during the clay gun action, and hydraulic efficiency system but needs to provide the low pressure low discharge during taphole drilling machine action.For can be with cover HYDRAULIC CONTROL SYSTEM these two equipment, the method for employing has following two kinds: 1, clay gun and taphole drilling machine be provided with the hydro-pump that is fit to its working condition requirement respectively at present.This method control is simple and reliable, but has increased the quantity of hydro-pump, has increased floor space.2, the shared hydro-pump of clay gun and taphole drilling machine is provided with reducing valve before the taphole drilling machine loop.This method has reduced the quantity of hydro-pump, and control is simple, but when the taphole drilling machine action did not need high pressure is provided, system still will export high pressure, wastes energy; In addition, reducing valve leaks easily, contaminated system.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of State of Blast Furnace preceding energy-saving hydraulic efficiency system.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: energy-saving hydraulic efficiency system before the State of Blast Furnace, it is characterized in that: it comprises an electronic pump, the input terminus and the programmable logic controller of electronic pump link, and output terminal connects with clay gun and taphole drilling machine; Described electronic pump is made up of open type pump, angle sensor, electronic regulator and proportional valve; The open type delivery side of pump connects with clay gun and taphole drilling machine; Angle sensor is gathered the actual value of open type POF; The ideal value of programmable logic controller output flow; Two input terminuss of electronic regulator connect with the output terminal of programmable logic controller and angle sensor respectively, after actual value and ideal value comparison, computing, export to proportional valve; The output terminal of proportional valve connects with the open type pump, adjusts the flow of open type pump.
Principle of work of the present utility model is: open type pump, proportional valve, angle sensor and electronic regulator have been formed electronic pump.Programmable logic controller is according to the difference of action equipment, to the ideal value of electronic regulator output flow.Angle sensor feeds back to electronic regulator with the actual value of open type POF.Electronic regulator with ideal value and actual value comparison, computing after, export to proportional valve, adjust the output flow of pump again by proportional valve, reach ideal value up to actual value.
The beneficial effects of the utility model are: 1, flow has been saved energy by better controlled; 2, the shared hydraulic efficiency system of clay gun and taphole drilling machine has reduced the quantity of components and parts, has saved cost; 3, control is simple, easy to operate; 4, adopt electronic pump, cancelled reducing valve, be beneficial to environmental protection.
