AI Technical Summary
The sootblower barrel was fixed to the steel frame and could not move, resulting in a difference in expansion between it and the furnace wall panel, which caused damage to the barrel.
The system adopts a combination structure of upper hoisting frame and inclined suspension rod, and absorbs the expansion difference between the soot blower and the protective plate through hinge and movable connection, so as to ensure that the soot blower barrel and the protective plate expand synchronously.
This effectively prevents damage to the sootblower barrel during operation, improving the stability and service life of the device.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a boiler technical field, concretely is a fuel oil waste heat boiler soot blower support and hang device. BACKGROUND
[0002] Fuel oil waste heat boiler, usually configure soot blower for removing the soot of boiler heating surface, this waste heat boiler wall usually adopts hot furnace wall structure, soot blower will be suspended in the boiler steel frame. Soot blower gun barrel goes into the furnace through the furnace wall guard plate and carries out soot blowing, because the furnace wall guard plate will expand downward in operation, and soot blower cannot move because fixed on the steel frame, so the expansion difference exists between the guard plate and gun barrel, thereby causing the gun barrel to be damaged. SUMMARY
[0003] In order to solve the above technical problem, the utility model provides a fuel oil waste heat boiler soot blower support and hang device, which can effectively solve the expansion difference problem of soot blower and furnace wall guard plate, and ensure that the soot blower gun will not be damaged in operation.
[0004] Its technical scheme is as follows: a fuel oil waste heat boiler soot blower support and hang device, which comprises a soot blower and a soot blower gun barrel connected to the soot blower, the soot blower gun barrel passes through the guard plate, the top of the soot blower is provided with a connecting rod, characterized in that the inner side of the guard plate is provided with an upper hoisting frame, the upper hoisting frame is hinged to one end of an inclined hoisting rod, the other end of the hoisting rod is connected to a channel steel, the connecting rod is connected to the channel steel, one end of the soot blower close to the guard plate is welded with a first steel plate, the first steel plate is located above the soot blower gun barrel, the inner side of the guard plate is welded with a second steel plate, and the first steel plate and the second steel plate are hinged.
[0005] Further characterized in that the upper hoisting frame and the hoisting rod are both provided with two and symmetrically arranged with the position of the soot blower gun barrel as the center line of symmetry.
[0006] The upper hoisting frame is composed of an upper horizontal steel plate welded to the guard plate, an intermediate vertical steel plate and a lower horizontal steel plate.
[0007] After adopting the utility model, the original connecting rod directly fixed on the soot blower is cancelled, an inclined guide rod is used for hoisting, and the end of the soot blower close to the guard plate is connected to the guard plate by using the hinged steel plate, which is changed to an active connection mode, so that the soot blower, the gun barrel and the guard plate will expand together, the expansion difference between the soot blower and the guard plate can be absorbed, and the gun barrel can be ensured not to be damaged. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 It is a structural schematic diagram of the utility model;
[0009] Figure 2 It isFigure 1 the left view. DETAILED DESCRIPTION
[0010] See Figure 1 , Figure 2 As shown in the figure, a fuel oil waste heat boiler soot blower support device includes a soot blower 7 and a soot blower gun barrel 8 connected to the soot blower 7, the soot blower gun barrel 8 passes through a guard plate 10, the top of the soot blower 7 is provided with a connecting rod 11, the standard soot blower is provided with a structure, the inner side of the guard plate 10 is provided with an upper hoisting frame, the upper hoisting frame is composed of an upper horizontal steel plate 1 welded to the guard plate 10, a middle vertical steel plate 2 and a lower horizontal steel plate 3, the middle vertical steel plate 2 is provided with a hole, one end of an inclined hoisting rod 4 is hinged to the hole at the middle vertical steel plate 2 and can rotate, the other end of the hoisting rod 4 is fixedly connected to both ends of a channel steel 9, the connecting rod 11 is connected to the channel steel 9, so that the hoisting rod 4 hoists the upper part of the soot blower 1.
[0011] The end of the soot blower 7 close to the guard plate 10 is welded with a first steel plate 5, the first steel plate 5 is located above the soot blower gun barrel 8, the inner side of the guard plate 10 is welded with a second steel plate 6, the first steel plate 5 and the second steel plate 6 are hinged, at this time, the connection is also movable.
[0012] In order to ensure the stability of hoisting, the upper hoisting frame and the hoisting rod 4 are both provided with two and are symmetrically arranged with the position of the soot blower gun barrel 8 as the center line of symmetry.
[0013] During the operation of the boiler, the top of the soot blower 7 and the end close to the guard plate 10 are both movably connected, can absorb the expansion difference, the soot blower 7, the soot blower gun barrel 8 and the guard plate 10 will expand together, which can ensure that the soot blower gun barrel 8 will not be damaged.
