Description

Technical Field

[0001] The utility model relates to the technical field of soot blowers, in particular to a semi-telescopic steam soot blower. Background Art

[0002] When the semi-retractable steam soot blower is working, the inner barrel is stationary, and the outer barrel drives the packing seal to reciprocate along the inner barrel in a straight line. Graphite packing is used to seal the inner and outer barrels. The wear between the inner barrel and the packing seal is continuous. At the same time, since the sootblowing barrel is long and is disturbed by the flue gas, the outer sootblowing barrel vibrates, and the packing wear is relatively large, resulting in steam leakage. Although the graphite packing has good lubrication effect and a certain degree of elasticity, which can compensate for the wear of the packing to a certain extent, the graphite packing has low strength and poor wear resistance, resulting in limited compensation. In addition, the gap between the packing cover and the inner barrel is too large. If the tightening force is too large, the packing can easily be squeezed out, and the leakage will be greater. Leakage can cause sootblower failure and endanger the safety of workers. Utility Model Content

[0003] The main purpose of the utility model is to provide a semi-retractable steam soot blower to solve the problem in the prior art that the packing seal of the semi-retractable steam soot blower is prone to steam leakage.

[0005] Furthermore, a plurality of annular grooves are provided inside the compression sleeve, the sealing ring is clamped in the annular grooves, a groove is provided on the outside of the sealing ring, and a spring for tightening the sealing ring is sleeved in the groove.

[0006] Furthermore, the sealing ring is made of carbon crystal material.

[0007] Furthermore, the pressing sleeve and the outer barrel are connected by a bolt; a sealing ring is provided between the pressing sleeve and the outer barrel.

[0008] Furthermore, the pressing sleeve includes an upper pressing sleeve and a lower pressing sleeve, and the upper pressing sleeve and the lower pressing sleeve are connected by bolt 2; a gasket is provided at the connection between the upper pressing sleeve and the lower pressing sleeve.

[0009] The utility model provides a compression sleeve and a sealing ring to perform secondary sealing, thereby improving the sealing performance of the steam soot blower; and the sealing ring is located on the outside of the graphite filler, and when the graphite filler is squeezed, the graphite filler will not be squeezed out due to the blocking effect of the sealing ring, and the problem of greater leakage will not occur; the compression sleeve is fixedly connected to the outer barrel, which can increase the supporting capacity of the outer barrel.

[0010] The utility model effectively solves the problem of steam leakage of the steam soot blower, ensures the economical operation of the unit, and realizes essential safety. BRIEF DESCRIPTION OF THE DRAWINGS
