Embodiment Construction
[0025] Attached below figure 1 , figure 2 for example:
[0026] Refer to attached figure 1 It can be seen that the blast furnace throttle valve angle detection equipment includes 1-gearbox device, 2-1# high-precision encoder, 4-2# high-precision encoder (5-control unit, 6-computer, 3-proportional valve, 9- hydraulic cylinder, 10-hydraulic oil pipe). In addition, the blast furnace throttle valve control unit also includes 7-throttle valve shaft A, 8-throttle valve connecting rod.
[0027] attached figure 2 It is the flow chart of the adjustment and control of the throttle valve angle of the blast furnace disclosed by the present invention.
[0028] The specific implementation steps of the method are as follows:
[0029] 1. Collect the actual angle value of the throttle valve of the blast furnace through two sets of encoder units, which are recorded as γ1 and γ2 respectively.
[0030] 2. Analyze and compare the signal value 1-γ1 and signal value 2-γ2 through the angle c...

The invention discloses a system and a device for controlling an angle of a blast furnace throttle valve through redundancy detection and belongs to the technical field of material distribution of blast furnaces, solving the problem of the occurrence of major production accidents because the blast furnace material flow is unstable and the blast furnace material line cannot be ensured when the throttle valve cannot act or the state cannot be fed back. The invention provides a protection measure for really implementing continuous detection control of the blast furnace throttle valve; the real-time continuous material distribution of the blast furnace can be finished by a plurality of redundancy detection manners, thereby ensuring that the manual controllable state of the blast furnace throttle valve is ensured by one and more additional detection manners if the single network communication has malfunction interrupt in the normal blast furnace production of the throttle valve; the production requirements under the special conditions can be simultaneously met.
Description
technical field [0001] The technology belongs to the control angle detection technology of a blast furnace throttle valve in the metallurgical industry, is mainly aimed at a redundant detection method of blast furnace equipment, and belongs to the technical field of blast furnace material distribution. During the normal operation of the blast furnace, a single encoder angle detection failure causes a major production accident that interrupts the blast furnace material distribution, and ensures the stable operation of the blast furnace material distribution equipment and the smooth and stable production of the blast furnace. Background technique [0002] For the metallurgical industry, the precise control of the blast furnace throttle valve plays an extremely important role in the metallurgical ironmaking industry, ensuring the full combustion of the blast furnace raw fuel. At present, many domestic iron and steel enterprises (especially large iron and steel enterprises) use ...
