A segmented gray cone mold

Abstract

The invention discloses a sectional type ash-cone mold. The sectional type ash-cone mold disclosed by the invention has the beneficial effects that by adoption of a sectional mode of dividing the ash-cone mold into an upper section, a middle section and a lower section, the difficulty that an ash cone is very easily damaged in demolding in the ash-cone manufacturing process is solved, the collision of the mold and the ash cone in demolding is reduced and the damage to the ash cone in demolding is avoided; in demolding, the three sections of ash-cone molds are disassembled in sequence from thetop to bottom, since the standard ash cone is in a triangular cone shape and is small in upper part and large in lower part, the sectional type ash-cone mold utilizes such shape, so the upper-layer smallest ash-cone mold is firstly disassembled, then the middle-layer smaller mold is disassembled, and finally the lower-layer biggest mold is disassembled; the lower the layers, the larger the containing cavity of the ash cone, the upper the layers, the smaller the ash cone, and the mold can be lifted and demolded easily in a manner of lifting the ash-cone mold from the bottom to top; in the process of removing the mold in the traditional ash-cone mold, the bonding area between the mold and the ash cone is overlarge and the ash cone can be damaged easily by improper force; the bonding damage between the mold and the ash cone possibly caused by primary demolding is avoided.

Description

technical field [0001] The invention relates to the field of experimental equipment for coal ash melting characteristics, in particular to a segmented ash cone mold. Background technique [0002] In coal quality analysis and research, coal ash melting characteristics are a very important measure of coal, which has an important impact on the safety of power plant boilers and cement kilns, especially the problem of coal ash melting and coking at high temperatures is directly related to the safety of water walls Therefore, it is very necessary to carry out experiments on coal ash fusion characteristics for industrial production safety. [0003] The existing ash fusion characteristic experiment is carried out by the ash fusion tester. First, the ash sample to be tested is pressed into a triangular pyramid-shaped ash cone through the ash cone mold. The temperature of the zone is evenly raised, and at the same time, a certain atmosphere of gas medium is introduced until the ash c...

Problems solved by technology

However, due to the unreasonable structural design of the existing molds for making ash cones, only one ash cone can be produced at a time, and the molded ash cones are easily damaged during the demoulding process of the ash cones. Production efficiency is not high
