Device for measuring repose angle and slip angle of pipeline coal slurry

Abstract

The invention discloses a device for measuring a repose angle and a slip angle of pipeline coal slurry, which comprises a supporting flat plate, two inclined supports are respectively connected to twoends of the bottom of the supporting flat plate through bracket bearings, the lower end of one inclined support a is welded on a gear bearing, and the lower end of the other inclined support b is welded on a central shaft of an inner ring gear; and also comprises an outer ring gear which is coaxial with the gear bearing, and the inner ring gear is respectively meshed with the gear bearing and theouter ring gear to rotate. A center shaft is arranged in the center of the gear bearing and connected with a connecting rod facing downwards, a longitudinally-arranged sliding rail is arranged on theconnecting rod, and a sliding block is arranged on the sliding rail. A crankshaft long rod is connected to the sliding block, and the other end of the crankshaft long rod is connected to a crankshaftbearing inner shaft; a crankshaft short rod is connected to the outer ring gear, the other end of the crankshaft short rod is connected to an outer shaft of a crankshaft bearing, and a crankshaft handle is arranged on the crankshaft bearing; the angle of a telescopic supporting flat plate can be adjusted by rotating the crankshaft handle, operation is easy, adjustment is easy, and precision is high.

Description

technical field [0001] The invention belongs to the technical field of equipment for measuring properties of pipeline transported slurry, and relates to a device for measuring the angle of repose and the slip angle of coal slurry transported through pipelines. Background technique [0002] The safe transportation of solid-liquid two-phase flow in long-distance pipelines needs to be established on the premise that the rheological properties of the slurry and the pumping link are stable. Otherwise, coal particles will slip during parking and cause pipe blockage, causing major economic and safety losses. Therefore, the laying angle of the pipeline on the undulating terrain needs to be smaller than the slip angle of the slurry (such as figure 1 shown) and the maximum value of the angle of repose. [0003] "A kind of measuring device for slurry sliding angle and angle of repose" (notification number CN204831963 U) on July 13, 2015 on the date of application shows that the measur...
