Abstract
Description
Technical Field
[0001] The utility model relates to the field of soot blowers, in particular to a novel air duct mechanism for soot blowers. Background Art
[0002] Sootblowers are commonly used in multi-pipeline continuous production fields such as thermal power and chemical industry, and are divided into steam, sound waves and airflow according to the sootblowing medium. Among them, rake-type sootblowers are widely used in the purging of flue gas denitrification devices of power station boilers because they can be retracted. However, the arrangement of the air duct part of the rake-type sootblowers in the prior art is too simple, usually in the form of an airflow main pipe with multiple branches, involving hot and cold alternation during use, and the airflow main pipe part lacks a supporting mechanism, which is easy to deform during use, thereby affecting the wind speed and further affecting the sootblowing effect. In this case, the airflow straight pipe needs to be regularly maintained and replaced, resulting in increased production costs and waste of labor. In view of the above situation, there is currently a lack of corresponding solutions. Utility Model Content
[0003] The utility model aims to overcome the shortcomings of the prior art and provide a new type of sootblower air duct mechanism with a more reasonable arrangement, stable output airflow, and especially the device as a whole is not easily deformed.
[0004] The device comprises an air flow main pipe, on which a limit plate is arranged, and on both sides of the air flow main pipe, air flow branches are also arranged;
[0005] On the limit plate, which is also the upper and lower part of the air flow main pipe, reinforcing rib assembly rods are respectively arranged;
[0006] An oblique reinforcement rib is arranged between the reinforcement rib assembly rod and the air flow branch pipe.
[0007] The effect achieved in this way is that, through the stable riveting of the reinforcing ribs, a stable triangular support is formed between the airflow branch pipe and the reinforcing rib assembly rod, thereby preventing the airflow branch pipe from deforming, or reducing its deformation risk.
[0008] The beneficial effects of the utility model are as follows: the utility model solves the problem of easy deformation of the wind flow branch pipe of the soot blower in the prior art, and by providing reinforcing ribs and a connecting base, the wind flow main pipe and the reinforcing rib assembly rod form a stable frame structure, thereby reducing the risk of local deformation of the wind pipe mechanism, reducing the maintenance frequency of the wind pipe, and reducing the production cost. The equipment is safer to operate and has more promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
