The invention discloses an adjustable signal feedback connecting rod of a blast furnace axial flow fan. The adjustable signal feedback connecting rod comprises a buckle groove, transmitter transmission shaft interfaces and fixing pin holes, wherein the buckle groove is formed in the top of the adjustable signal feedback connecting rod, the transmitter transmission shaft interfaces are arranged below the buckle groove and vertically distributed on the adjustable signal feedback connecting rod at equal intervals, and the plurality of fixed pin holes are formed in the side part of the adjustablesignal feedback connecting rod and communicate with the transmitter transmission shaft interfaces. By means of the adjustable signal feedback connecting rod, stationary blade feedback signals can be increased or decreased according to actual needs without replacing components such as a transmitter, and thus setting of the stationary blade feedback signals is achieved.
Description
technical field [0001] The invention belongs to the technical field of axial flow blower, and more specifically relates to an adjustable signal feedback connecting rod of a blast furnace axial flow blower. Background technique [0002] When the blast furnace axial flow blower unit is running, the air volume needs to be adjusted at any time according to the blast furnace demand. When adjusting, the oil motor pushes the stationary vane to move, the stationary vane changes the angle, and at the same time changes the flow space and compression ratio inside the fan to achieve the purpose of adjusting the air volume. . When adjusting the vane angle through the oil motor, the oil motor moves back and forth horizontally, the displacement scale of the oil motor drives the feedback signal connecting rod to swing, the lower end of the connecting rod is connected to the transmission shaft of the transmitter through the interface, and the swing of the connecting rod will drive the transm...
