Ash fusibility tester and standard indicating supporting plate thereof

Abstract

The invention relates to the technical field of test equipment, in particular to an ash fusibility tester and a standard indicating supporting plate thereof. The standard indicating supporting plate comprises a supporting plate body and a plurality of ash taper holes formed in the front surface of the supporting plate body, wherein the supporting plate body is disc-shaped; the ash taper holes are blind holes in the shapes of regular triangles; the ash taper holes are distributed in the circumference of the supporting plate body in an array manner; at least one position indicating point is arranged on the outer side of one corresponding edge of each ash taper hole, and used for indicating the vertical plane position of one corresponding ash taper to be tested, so that images, of the ash tapers to be tested, shot by a camera device in the testing process can be in consistent with an image preset in a picture recognition system. The accuracy of ash fusibility testing results is improved.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an ash melting tester and a standard indicating pallet thereof. Background technique [0002] The ash melting test instrument is an instrument used to detect the melting of the ash cone of the coal sample. The melting of the ash cone is directly related to whether there is sintering in the boiler of the power plant and the severity of the sintering, and has a great impact on the safe use of boilers and cement shaft kilns. . In the current ash melting tester, the coal sample ash cone is arranged on the support plate, and the support plate is fixed on the support cup. During the test, the support cup drives the supporting plate to rotate, so that the coal sample ash cone rotates in the high-temperature furnace tube and heats up evenly until the coal sample ash cone reaches a molten state. During this process, the camera mechanism takes pictures in real time, and through...

Problems solved by technology

[0003] The ash cone used in the ash melting test is made into a triangular cone according to the national standard GB / T219-2008. The bottom surface is an equilateral triangle, and one side of the cone is perpendicular to the bottom surface. During the test, the ash cone sample will be perpendicular to the cone It is bent on one side of the ground. When the ash cone is placed in the supporting plate before the test, because the ash cone sample is small, the elevation (one side of the ash cone perpendicular to the ground) is not obvious, and it is easy to cause the ash cone to be tested. If the placement of the sample is inconsistent, the captured image obtained is inconsistent with the system preset image, which will affect the test effect

Due to the long time of an ash fusion test, the number of samples injected on the ash cone supporting plate is usually increased to improve the test efficiency, but this undoubtedly reduces the distance between two adjacent coal sample ash cones. If multiple ash cones The placement position of the sample is inconsistent, and the ash cones of two adjacent coal samples may be relatively bent when deformed, resulting in "cross-sampling" and affecting the test accuracy
