Method for quick online replacement of trolley for sintering machine

Abstract

The invention discloses an online quick trolley changing method of a sintering machine, belongs to the technical field of sintering machines and provides a method which is used for quick trolley change of the sintering machine in an online state and is more convenient to operate.A pull gap of 20-50 mm is formed in a tail swing frame in the tail direction through ejection.Therefore, when a trolley required to be changed is hoisted later, gaps of 10-20 mm can be reserved between the trolley required to be changed and front and back adjacent trolleys through front-and-back folding and pulling, and the trolley required to be changed can be more conveniently hoisted away.In addition, the trolleys in front and back of the trolley required to be changed can be also fixed by further arranging limiting parts, the phenomenon that the front and back adjacent trolleys move towards the middle after the trolley required to be changed is hoisted away can be avoided, and a standby trolley can be rapidly and accurately transferred to the position where the trolley required to be changed is located.Furthermore, a material corresponding to the upper portion of the trolley required to be changed can be also wetted to make ignition and sintering of the sintering machine unable, and further convenience is brought to better trolley operation.The online quick trolley changing method can bring huge economic benefits during actual work.

Description

technical field [0001] The invention belongs to the technical field of sintering machines, and in particular relates to a method for quickly replacing a trolley on-line for a sintering machine. Background technique [0002] The sintering machine is mainly used in the sintering operation of the metallurgical sintering plant, and is suitable for the sintering treatment of various ore powders; a sintering machine is often connected by multiple end-to-end trolleys to form a ring, and the sintering machine trolley runs in an ellipse. Shaped closed loop operation. The sintering machine trolleys load the sintering mixture from the head end of the sintering machine one by one, then ignite in the ignition device, and then run along the upper running track to the tail end of the machine; the raw materials are sintered during the running process to the tail end of the machine ; After the trolley runs to the tail end of the machine, it tilts along the circumference of the running track...

AI Technical Summary

Problems solved by technology

[0004] First, during the normal operation of the sintering machine, the adjacent sintering machine trolleys are often in close contact, so if there is not enough gap reserved, the hoisting of the trolley to be replaced and the lifting of the spare trolley It is very difficult to enter the original position of the trolley to be replaced; especially when the trolley to be replaced is hoisted away, if the position of the adjacent trolleys is not limited, the spare crane cannot be hoisted into the original replacement platform. car location

However, the above-mentioned publication 1 does not provide a method that can solve this problem, which makes it very difficult for those skilled in the art to operate according to the method described in it, and cannot achieve the effect of significantly shortening the time for replacing the trolley as claimed by it.

[0005] Second, due to the limited operating space from the head end of the sintering machine to the ignition device, the replacement of the trolley is often carried out downstream of the ignition device; however, the materials located in the trolley to be replaced after ignition and sintering The material in the adjacent trolley is agglomerated, so that the trolley cannot be lifted off directly; therefore, it is necessary to break up the sintered materials in the trolley to be replaced before hoisting away the trolley to be replaced

However, when the above method is adopted, since the thickness of the cloth in the trolley to be replaced is only 180mm-210mm, which is far lower than the normal thickness of the cloth, that is, the cloth in the trolley to be replaced and the cloth in the adjacent trolley are in a "concave" shape. "shape, the result is that the wind resistance of the cloth in the trolley to be replaced is much smaller than the wind resistance of the cloth in the front and back of the car; so that most of the airflow will flow through the place where the trolley needs to be replaced, resulting in the airflow of the trolley with the rest of the normal cloth. The reduction will seriously affect the sintering effect of the materials in the rest of the normal distribution trolley
