A method for rapid repair of the outer screen of ash machine

Abstract

The invention discloses a method for quickly repairing the outer screen of a lime machine, and relates to the technical field of the calcining ash process in the production of soda ash by the ammonia-soda method, comprising the following steps: prefabricating a non-leakage screen; selecting a leak-repairing screen According to the size of the crack on the outer screen of the ash machine, select a leak-trapping screen of the corresponding specification; process the outer screen; install the leak-trapping screen, remove the cutting motor and cutting wheel, and clamp one end of the fastener on the outer screen On the side of the notch, snap the trapping screen to the other end of the fastener, and use bolts to fix the outer screen, the fastener and the trapping screen. The method for quickly repairing the outer screen of the ash machine is fast and durable after repair, convenient for repair, short in time and low in repair cost, and at the same time avoids the need to temporarily cut an old screen and bind it with thin iron wires in the existing repair method Fixed, because the sandstone is broken, or the large grains of sand are squeezed in the interlayer, it will usually be damaged in less than a day.

Description

technical field [0001] The invention relates to the technical field of the calcification ash process in the production of soda ash by the ammonia-soda method, in particular to a method for quickly repairing the outer screen of a calcination machine. Background technique [0002] At present, in domestic production of soda ash by ammonia-alkali method, the calcification ash machine is mainly to react the quicklime burned in the lime kiln with water to produce milk of lime and remove unburned limestone and large particles of impurities. The size of the ash machine is Φ3020×22791. There are three layers of screens in the rotary screen at the tail of the ash machine, all of which are steel mesh, of which the outer screen is divided into eight pieces. The material was originally carbon steel, and later changed to stainless steel. Straight 6, the two long sides are welded with angle steel and fixed on the screen frame with bolts. The outer screen mesh will be partially broken aft...
