Device for testing impact resistance of refractory castable for boiler cold ash bucket

Abstract

The invention provides a device for testing the impact resistance of a refractory castable for a boiler cold ash bucket. The device comprises a base, a storage seat is arranged at the top of the base;a sample plate is erected above the storage base, supporting columns are arranged on the two sides of the storage base, a top plate is arranged above the supporting columns, a rod sleeve is arrangedin the middle of the top plate, a limiting rod is arranged in the rod sleeve, a pressing plate is arranged above the limiting rod, a connecting plate is arranged below the limiting rod, a driving device is arranged at the top of the pressing plate, and a plurality of conical rods are arranged at the bottom of the connecting plate. According to the present invention, the impact resistance test apparatus is used for the impact resistance test of the refractory castable of the boiler cold ash hopper, can simulate the actual boiler condition by erecting the sample plate on the object placing seatand repeatedly heating and cooling, can simulate the high temperature powder slag falling condition by repeatedly hammering the sample plate through the conical rod, can improve the test accuracy, andhas strong practicality.

Description

technical field [0001] The invention belongs to the technical field of industrial equipment, and relates to a test device for impact resistance of refractory castables for cold ash hoppers of boilers. Background technique [0002] The cold ash bucket refers to the bucket-shaped furnace bottom structure formed by the water-cooled wall at a certain inclination angle at the lower part of the pulverized coal boiler furnace. During the use of the existing cold ash hopper, due to the high temperature of the powder slag falling from the lower part of the furnace, the pouring material of the cold ash hopper is easy to deform during repeated heating and cooling, and even cracks when it cannot withstand the impact. A test device to ensure its impact resistance for increased safety. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a test device for the impact resistance of refractory castables for...
