Guide blade angle linkage adjusting device

Abstract

The invention relates to the field of mining machinery, and provides a mine mechanical accessory which is a guide blade angle adjusting device. According to the guide blade angle adjusting device, theangle of the flow guide blade can be conveniently adjusted in a one-time linkage mode through the guide blade angle adjusting device, and the angle consistency of the adjusted flow guide blades is good; a guide blade angle linkage adjusting device comprises a flow guide blade assembly, the flow guide blade assembly comprises a flow guide blade and a flow guide blade support; the flow guide bladecomprises a rotating shaft and a straight plate which is fixedly connected to the rotating shaft in the axial direction, the rotating shaft is arranged on an upper flange and a lower flange in a swinging mode; the shaft head part, protrudes out of the upper flange, of the rotating shaft is sequentially provided with a connecting part, a supporting part, an adjusting part and a locking part from bottom to top, and the adjusting part is provided with a chord section which is symmetrical about the axis section of the rotating shaft; and the guide blade angle linkage adjusting device further comprises a top flange with the diameter larger than the diameter of the upper flange, a connecting plate which is equal to the number of the flow guide blades and is uniformly distributed along the circumferential direction of the top flange and is arranged on the top flange in a swinging mode, and the connecting plate is movably arranged on the chord section of the corresponding rotating shaft.

Description

technical field [0001] This technology relates to the field of mining machinery. It provides a mining machinery accessory, which is a device for adjusting the angle of the guide vane. Using the angle adjustment device for the guide vane, it is convenient to adjust the angle of the guide vane at one time. Good consistency. Background technique [0002] The guide vane is an important part of the coal mill separator. Its setting method is that a number of guide vanes are evenly distributed on the guide vane bracket along the circumference to form a guide vane assembly. The guide vane assembly is fixedly connected to the coal mill In the powder machine frame, the guide vane assembly is in line with the axis of the rotor. [0003] The guide vane bracket is mainly composed of a group of flanges arranged in parallel. The intersection of the axis of the rotating shaft of each guide vane and the flange is the node of the rotating shaft and the flange. The circle determined by each n...

Problems solved by technology

[0006] In the prior art, as far as the angle of the guide vane is concerned, the connection setting modes of the guide vane and the guide vane bracket are as follows: 1. Non-adjustable type, the guide vane is fixedly connected to the guide vane bracket with a guide vane angle of a fixed value When it is necessary to adjust the angle of the guide vanes, the guide vanes can only be replaced as a whole group, which is difficult and time-consuming to disassemble; It takes a long time to adjust the angle of one round of guide vanes, which makes it impossible to adjust the angle of guide vanes in real time, and the angle consistency of the adjusted guide vanes is poor, so the fineness of the finished product is not easy to control, and the quality of pulverized coal is difficult It meets the standard for kiln use, and the economic benefit is poor; 3. Multi-piece adjustment, the guide vane is oscillatingly set on the guide vane bracket, and the stepping motor or servo motor is controlled by the electronic control system to drive the rotation of the guide vane shaft to realize the guide vane Angle linkage adjustment, although this adjustment method can realize the linkage adjustment of guide vane angle, but its manufacturing cost is high, and in addition, due to the influence of harsh working conditions, its reliability is also poor
