Abstract
The utility model relates to a telescopic type soot blower which makes use of steam or compressed air to clean deposition and slag bonding on the heating surface of a boiler, particularly a superheater, a reheater and a coal economizer, in order to enhance the thermal efficiency of the boiler and ensure the full load and the long period normal operation of the boiler. The utility model is mainly characterized in that a long inner tube of the original soot blower is canceled; a short inner tube structure which is in integral forming with a packing box of a sports car is adopted; the short inner tube is connected with a valve by a flexible metal pipe and a connecting pipe to realize the transmission of a soot blowing medium so that the sealing performance to the soot blowing medium (the steam or the compressed air) is conspicuously improved, the soot blowing effect is ensured and better energy-saving function is also provided.
Description
The utility model relates to a kind of telescopic boiler sootblower
The boiler sootblower of present domestic use mainly by valve, girder construction, valve control mechanism, sport car gearbox parts and sport car stuffing box parts, ash gun, travel switch and walk line mechanism, sealed support and long in pipe form.It is exactly this pattern that Hubei Boiler Auxiliary Machinery Plant produces C304 type retractable soot blower.During the soot blower operation, ash gun is for the helical movement, and two nozzles on the ash gun front end shower nozzle with two strands of medium jet directive boiler heating surfaces, reach the purpose of blow over clearly ash and slagging scorification along helical trajectory.In long pipe be exactly this soot blower for realizing screw, be transferred to nozzle design blowing grey medium.Mainly there is following shortcoming in this design: pipe is difficult to guarantee packing seal effect extreme difference with the axiality of sport car filler chamber in (1); (2) in pipe oversize give interior pipe rear end and valve connection place sealing gasket fastening be subjected to when bringing difficulty and operation the effect of sport car filler frictional force make in pipe have the periodically trend that rotatablely moves and the operating vibration of positive and negative direction, feasible sealing gasket herein very easily damages; (3) long interior pipe feasible replacing ash gun and sport car connection place sealing gasket very inconvenient----need the dismounting valve to extract interior the pipe out, thus influence described filler in (1) (2) and sealing gasket; (4) when adopting the wet type gas vapor to do to blow grey medium, above-mentioned sealing leak easily cause soot blower control electric part make moist malfunctioning, damage; There is very big longitudinal frictional force in when (5) soot blower moves between pipe and filler, increased the sport car load.
The purpose of this utility model is to design a kind of new telescopic boiler sootblower at the shortcoming in the present telescopic boiler sootblower use.
The purpose of this utility model is finished as follows: connect the interior pipe holder of being made up of supporting member and connecting flange on the rear bearing cover of old-fashioned retractable soot blower sport car stuffing box parts, manage mounting flange on the connecting flange of interior pipe holder one end, connecting by screw, the interior Guan Yiduan of the weak point of sport car stuffing box components interior stretches out and is fixed on the interior pipe mounting flange, the external part of pipe connects 90 degree elbows in short, and the elbow other end connects metal hose joint; Metal hose joint connects metal hose, and the other end of metal hose connects " second " font tube connector, and the other end of " second " font tube connector is connected with the valve on being fixed on the soot blower end plate.Pipe holder in sport car stuffing box rear bearing cover and supporting member, connecting flange casting or the integrally welded formation, the supporting member bilateral symmetry leaves square hole.The outer face of the connecting flange on the interior pipe holder is provided with round boss.
The utility model has the advantages that: (1) since adopt be short in pipe be convenient to realize being integral with sport car, thereby the axiality of pipe and filler chamber in can guaranteeing helps improving sealing effectiveness; (2) the valve export place be sealed to common static seal, to its influence, airtight quality guarantees easily when having eliminated the soot blower operation with metal hose simultaneously; (3) short interior pipe helps timely leakage eliminating for the sealing gasket of changing ash gun and sport car connection place provides convenience; (4) pipe only exists and rotatablely moves with filler in, does not have motion to axial, has reduced mutual frictional force, has promptly reduced the sport car load, provides load space for compressing filler, makes that can compress filler with bigger thrust reaches sealing effectiveness.
