Abstract
The invention belongs to the technical field of metallurgical sintering production, and particularly relates to a micro-negative-pressure regulating valve of a sintering machine. The micro-negative-pressure regulating valve comprises a valve and a turning plate with a turning plate shaft. The micro-negative-pressure regulating valve is characterized by further comprising a push-press rod, a compensator, a driving mechanism, a guide plate and a push-pull hinged support, the push-press rod is connected with the turning plate, the compensator is arranged on the valve, the driving mechanism is connected with the push-press rod, the guide plate is arranged on the valve, and the push-pull hinged support is arranged on the turning plate. The micro-negative-pressure regulating valve of the sintering machine has the advantages that the push-press rod is controlled by the driving mechanism to directly adjust the opening of the turning plate, so that the negative-pressure of a bellow can be regulated, and the purpose of regulating the micro-negative-pressure can be achieved; the push-press rod directly acts on the turning plate, so that the micro-negative-pressure regulating valve is easy to control when the micro-negative-pressure is for regulating the micro-negative pressure, and a phenomenon of blockage of damp materials between the turning plate and the valve of the micro-negative-pressure regulating valve is completely eradicated.
Description
Technical field
The invention belongs to metallurgy sintered production technical field, especially relate to the micro-negative pressure adjustment valve of a kind of sintering machine.
Background technique
When smelting industry carries out sintering work, what the ignition of sintering process device needed is micro-negative pressure igniting.If negative pressure value is high, flare can directly enter ore bed, makes the ignition quality on ore bed surface bad, and the flare that simultaneously enters ore bed is also insufficient to the carbon burning in ore bed, causes whole ignition quality bad, and the reject rate of sintering deposit increases.Therefore igniting need to be incremental, the sintering deposit of ability output high-quality.
Control the size of negative pressure value, often adopt micro-negative pressure adjustment valve to regulate.The micro-negative pressure adjustment valve used at present, mainly contain two kinds, and a kind of is single turnover panel negative pressure adjustment valve that declines, and a kind of is two turnover panels negative pressure adjustment valves that decline.Its common feature is: be no matter single turnover panel negative pressure adjustment valve or two turnover panel negative pressure adjustment valve that declines that declines, their rotating plate shaft all is arranged on the central position of turnover panel.Advantage be turnover panel under the effect of negative pressure, the suffered pressure of the turnover panel of rotating plate shaft both sides is suitable, the resistance be subject to during the rotating plate shaft upset is little.Owing to will controlling negative pressure, the end face width is certain, and turnover panel has just determined negative pressure value with the gap length of valve body.For example, single turnover panel has the uniform gap of twice with valve body, and two turnover panels have three gaps, road, total aperture (namely gap) that the negative pressure value that supposing to reach needs needs is L, the gap that single turnover panel leaves is 1/2L, and the gap that two turnover panels leave is 1/3L, and gap is less, the tide material more easily got off between turnover panel and valve body blocks, and this is also the current easy out of order main cause of micro-negative pressure Flap valve in use.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, open and close the micro-negative pressure adjustment valve of stable sintering machine, the turnover panel that can effectively stop micro-negative pressure adjustment valve blocks phenomenon with the tide material existed between valve body.
The objective of the invention is to realize by following technical proposals:
The micro-negative pressure adjustment valve of sintering machine of the present invention, comprise valve body, turnover panel with rotating plate shaft, characterized by further comprising the push strut be connected with described turnover panel, be located at the compensator on described valve body, the driving mechanism that is connected with described push strut, be located at the guide plate on described valve body, be located at the push-and-pull free bearing on described turnover panel
One end of described push strut is sealing stifle end, and the other end is telescopic end,
Described driving mechanism is connected with the sealing stifle end of described push strut respectively with described compensator,
The two ends of described rotating plate shaft are fixedly connected on described valve body, and described rotating plate shaft is positioned at the top of described turnover panel, and the push-and-pull free bearing on described turnover panel and the telescopic end of described push strut are hinged.
Described driving mechanism comprises the Electrohydraulic push rod that is connected with the sealing stifle end of described push strut, the push rod pedestal that Electrohydraulic push rod is connected therewith, and described push rod pedestal is fixed on described valve body.
Described driving mechanism comprises the lever that the sealing stifle end of an end and described push strut is hinged, the connecting rod that the lever the other end is hinged therewith, the crank that connecting rod is connected therewith, lever pedestal and motor power device, the middle part of described lever is hinged with the lever pedestal be fixed on described valve body.
Advantage of the present invention:
The micro-negative pressure adjustment valve of sintering machine of the present invention is directly adjusted the switching degree of turnover panel by the driving mechanisms control push strut, to adjust the negative pressure of bellows, reach the adjustment operation of micro-negative pressure.Because push strut acts directly on turnover panel, be easy to control and adjust, the turnover panel of having stopped micro-negative pressure adjustment valve blocks phenomenon with the tide material existed between valve body.
The accompanying drawing explanation
Fig. 1 is a kind of driving mechanism structure schematic diagram of the present invention.
The structural representation that Fig. 2 is the another kind of driving mechanism of the present invention.
Embodiment
Further illustrate the specific embodiment of the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, 2; the micro-negative pressure adjustment valve of sintering machine of the present invention; comprise valve body 7; with the turnover panel 8 of rotating plate shaft 6, characterized by further comprising the push strut 9 be connected with described turnover panel 8, be located at the compensator 4 on described valve body 7; driving mechanism is connected with described push strut 9; be located at the guide plate 5 on described valve body 7, be located at the push-and-pull free bearing 11 on described turnover panel 8, guide plate 5 is that the top that acts on valve body 7 is used for protecting rotating plate shaft 6 positions not advance foreign material.
One end of described push strut 9 is sealing stifle 10 ends, and the other end is telescopic end,
Described driving mechanism is connected with sealing stifle 10 ends of described push strut 9 respectively with described compensator 4,
The two ends of described rotating plate shaft 6 are fixedly connected on described valve body 7, and described rotating plate shaft 6 is positioned at the top of described turnover panel 8, and the push-and-pull free bearing 11 on described turnover panel 8 is hinged with the telescopic end of described push strut 9.
Described driving mechanism comprises the Electrohydraulic push rod 3 that is connected with sealing stifle 10 ends of described push strut 9, the push rod pedestal 2 that Electrohydraulic push rod 3 is connected therewith, and described push rod pedestal 2 is fixed on described valve body 7.
