AI Technical Summary

Technical Problem

The fixed spacing of the rake tubes in existing rake soot blowers makes it difficult to adjust flexibly according to different boiler structures or flue sizes, resulting in poor soot removal effect and affecting equipment efficiency and production continuity.

Method used

A movable positioning structure and a sealing connection structure were designed, including a slide rail, a slider, a positioning rod, and a sealing nut, to achieve the spacing adjustment and sealing of the auxiliary rake tube. The flexible positioning and sealing of the auxiliary rake tube are achieved through a spring structure and threaded connection.

Benefits of technology

It improves the applicability and cleaning efficiency of rake soot blowers, ensures the reliability and safety of the equipment, and simplifies the connection and maintenance process.

Abstract

This utility model discloses a rake tube for a cement denitrification rake-type sootblower, including a movable positioning structure installed on the side surface of the main rake tube and the upper surface of the auxiliary rake tube for moving the auxiliary rake tube below the main rake tube, and a sealing connection structure for sealing the connection between the main rake tube and the auxiliary rake tube. By lifting the positioning rod upwards with a handle, the spring structure is stretched, and the positioning rod is pulled out of the positioning hole. With both positioning rods on both sides of the main rake tube lifted upwards simultaneously, the slider can be manually slid, allowing the slider and the auxiliary rake tube to slide below the main rake tube. After sliding to the appropriate position, releasing the handle pulls the baffle and positioning rod downwards through the spring structure's restoring force, causing the positioning rod to engage in the positioning hole, thus locking the position of the auxiliary rake tube. This allows for flexible adjustment of the auxiliary rake tube spacing, thereby improving the applicability and cleaning efficiency of the rake-type sootblower and enabling it to better adapt to the needs of different cleaning scenarios.
