Method for mounting support column of slag notch of incinerator

Abstract

The invention discloses a method for mounting a support column of a slag notch of an incinerator. The method includes steps of 1), properly positioning so that the angle between an oblique support plate and a horizontal plane is 40 degrees; 2), unscrewing a nut on a bolt connected between an upright column body and an upright column connector so that the upright column connector can freely rotate around the bolt; 3), adjusting the position of the upright column connector so that a support surface of the upright column connector completely contacts with the oblique support plate; 4), adjusting the elevator of the bottom of the upright column body; 5), welding a base of the upright column body with an embedded plate on a foundation; 6), firmly welding the upright column connector with the oblique support plate; and 7), screwing down the nut and firmly welding a hinge position. During installation, the upright column connector can sufficiently contact with the oblique support plate, accordingly, the problem of difficult welding is solved, work efficiency is improved, and installation time is shortened. In addition, a proper oblique angle of the oblique support plate is guaranteed, a support surface of the oblique support plate can be completely fit with the bottom surface of the slag notch, and service lives of the slag notch and the support column are prolonged.

Description

technical field [0001] The invention relates to a method for installing a support column, in particular to a method for installing a support column for an incinerator slag trough used in the iron and steel metallurgy industry. Background technique [0002] At present, incinerators are often used to incinerate metallurgical waste in the iron and steel metallurgical industry. The slag outlet of the furnace needs to be at least ten meters high from the ground, and a slag outlet is installed obliquely at the slag outlet. After the metallurgical waste in the incinerator is incinerated, the residue weighs tens of tons. When the slag discharge door is opened, the residue from the incinerator rolls into the collection bin on the ground through the slag discharge trough and is processed uniformly. In order to bear such a heavy residue after incineration, the slag discharge tank must be welded with thicker steel plates. The total length of the slag discharge tank is generally about 2...

AI Technical Summary

Problems solved by technology

Due to the integrated structure of the column 2a, the angle of the top support surface of the column 2a is fixed, and the angle of inclination of the inclined support plate 1a after welding on the top support surface of the column 2a is also fixed and cannot be adjusted.

Therefore, this incinerator slag trough support column has the following deficiencies when it is welded with the bottom of the slag trough: 1. In actual installation, it is impossible to ensure that the inclination angle of each inclined support plate 1a is consistent and the inclined surface is at the same angle after welding. On the surface, after hanging the slag trough on several support columns from high to low, the bottom surface of the slag trough cannot be guaranteed to fit with the support surface of each inclined support plate 1a. , the residues often have a higher temperature. Under the impact force of the falling residues, the impact and vibration force of the slag trough on each support column is different, resulting in poor welding after bonding with the bottom surface of the slag trough. The slanting support plate 1a is desoldered, and then the slanting support plate 1a and the slag discharge groove are uniformly distributed, which has seriously affected the smooth slag discharge of the incinerator, and shortened the service life of the slag discharge groove and the support column; The gap between the inclined support plate and the slag discharge tank is often filled with fillers in the gap between the slag discharge tank and the inclined support plate, but this method only realizes the contact between the inclined support plate and the outside of the slag discharge tank, but the inside is still There are gaps, the same defects as above, and the installation efficiency is low, it takes a long time, and the connection is also difficult
