Description

Technical Field

[0001] This utility model relates to the field of roasting furnace technology, specifically to a roasting furnace fire channel wall correction device. Background Technology

[0002] Open-type calcining furnaces are one of the key process equipment in the production of prebaked anodes for aluminum. During production, due to various factors such as high temperature, load, and material aging, the furnace flue walls often deform and crack, causing the furnace feed box to narrow and unable to meet the anode charging requirements, affecting the yield and quality of prebaked anodes, and also posing safety hazards. To ensure the normal operation of the calcining furnace and the quality of prebaked anodes, the method of dismantling and rebuilding individual deformed flue walls is often used to repair them. Due to heavy production tasks and tight schedules, newly built flue walls are usually put into production before they are fully dried, resulting in a shorter service life than expected and increased production and operating costs. Utility Model Content

[0003] In view of the problems of short service life and high production cost of the fire channel wall in the above-mentioned prior art, this utility model provides a fire channel wall correction device for roasting furnace.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A furnace flue wall straightening device includes two supporting straightening plates, jacks, lifting lugs, connecting rods, and steel wire ropes. The two supporting straightening plates are arranged opposite each other. One supporting straightening plate has multiple jacks, and the other supporting straightening plate has multiple connecting rods. The jacks and connecting rods are perpendicular to the supporting straightening plates. Each jack corresponds to one connecting rod, and the distance between two adjacent connecting rods is equal to the distance between the two jacks corresponding to the two adjacent connecting rods. The end of the connecting rod away from the supporting straightening plate has a detachable connecting part. The diameter of the connecting part is smaller than the inner diameter of the screw hole of the jack, and the connecting rod is connected to the jack through the connecting part. The supporting straightening plate also has lifting lugs, and the steel wire ropes are connected to the lifting lugs.

[0006] Furthermore, the supporting and correcting plate is made of channel steel.

[0007] Furthermore, the jack is a hydraulic jack.

[0008] Furthermore, the lugs are disposed at both ends of the support and correction plate.

[0009] Furthermore, the surface of the connecting part is provided with a thread that matches the inner hole of the screw of the jack.

[0010] Furthermore, the spacing between the plurality of jacks is equal.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention provides a calcining furnace fire channel wall straightening device. Through a combination design of a supporting straightening plate, jacks, and connecting rods, it achieves efficient straightening of the calcining furnace fire channel wall. The jacks provide stable straightening force, precisely controlling the degree of straightening to meet different straightening needs, while the connecting rods ensure stability during the straightening process. The design of the lifting lugs and wire ropes facilitates the installation and disassembly of the device. This device can significantly improve the maintenance efficiency of the calcining furnace fire channel wall, extend its service life, reduce downtime and production losses caused by fire channel wall deformation, and lower maintenance costs.
