Detailed Description
As shown in the figures, the embodiment of the present invention provides a soot blower, which includes a soot blowing pipe 1, a sealing device 2 and a swing unit 6; the soot blowing pipe 1 is penetrated in the sealing device 2, and the soot blowing pipe is provided with a steam pipeline 3, and the last solenoid valve 5 that still installs of steam pipeline 3, soot blowing pipe subsection are corrugated metal pipe 4, and the gas outlet of steam pipeline 3 is connected with tee bend ball valve 701, tee bend ball valve 701 is equipped with an entrance point and two exit ends, and the entrance connection steam pipeline 3 of tee bend ball valve 701, an exit end of tee bend ball valve 701 is equipped with fan-shaped nozzle 702, and another exit end is equipped with conical nozzle 703, swing unit 6 installs motor 604 on the mounting panel 603 including installing mounting panel 603 in sealing device 2, install connecting rod one 601 on the motor 604, the last articulated connecting rod two 602 that has of soot blowing pipe, and connecting rod one 601 is articulated with connecting rod two 602.
The starting part of the soot blowing pipe 1 is hinged on the sealing device 2, and the steam pipeline 3 is connected with an external air inlet pipe 8.
The sealing device 2 comprises two layers, namely a hydrophobic sealing layer 201 and a high-temperature sealing layer 202, wherein the hydrophobic sealing layer 201 surrounds the outer side of the high-temperature sealing layer 202.
The working principle of the utility model is as follows, when starting the motor 604 in the swing unit 6, the motor 604 rotates and drives a crank connecting rod 601 rotatory, the rotation of a connecting rod 601 makes two 602 removal of connecting rod, the articulated mode of blowing pipe 1 and two 602 of connecting rod is as shown in figure 2, can improve the stability of connecting like this, again because the originated portion of blowing pipe 1 articulates on sealing device 2, thereby reciprocating swing is done to blowing pipe 1, corrugated metal pipe 4 can carry out certain compensation to the swing of blowing pipe 1, extension blowing pipe 1 life. In the sealing device 2, the hydrophobic sealing layer 201 and the high-temperature sealing layer 202 are matched to separate high-temperature steam, so that good working conditions of the soot blowing pipe 1 are ensured. The steam pipeline 3 is connected with the external air inlet hose 8, when the electromagnetic valve 5 is opened, high-temperature steam in the external air inlet hose 8 flows through the steam channel 3 and is ejected from the nozzle part of the soot blowing pipe, and the soot blowing process of the boiler is realized. When the soot blowing area of the boiler is large and the soot deposition amount is small, the three-way ball valve 701 connected with the fan-shaped nozzle 702 is opened, the fan-shaped nozzle 702 can reduce the outlet pressure of steam, the steam flow rate is reduced, and the risk that the steam blows the heating surface of a hearth is reduced. Different soot blowing angles can be obtained through the matching of the soot blowing pipe 1, the swing unit 6 and the soot blowing pipe nozzle assembly 7, so that the soot blowing area is increased, and soot blowing is effectively carried out.
