After the wind pipe is connected with the wind distribution plate, the wind cap is directly assembled on the upper part of the wind pipe, and the newly manufactured fixing part passes through the reserved round hole of the wind cap to be connected with the wind pipe through threads. However, the hood, the air pipe and the fixing part are three different independent components, when a new hood is replaced, the fixing part is required to be detached at the same time, and the sealing gasket between the fixing part and the hood is required to be readjusted every time when the new hood is replaced, so that the time required for maintenance is increased; meanwhile, the fixing part and the hood are sealed by a sealing gasket, but the problem of air tightness still exists.

As a further improvement of the utility model, the connecting rod is provided with external threads on the external threaded connecting rod which are matched with the internal threads of the threaded hole, so that the connecting rod is in threaded connection with the mounting part.
As a further improvement of the utility model, the outer side of the hood is fixedly provided with a connecting part, and the connecting part is internally provided with an inner hexagonal hole for disassembling the hood.
As a further improvement of the utility model, the upper part of the air pipe is uniformly provided with air pipe holes.
As a further improvement of the utility model, the outer side of the lower part of the hood is uniformly provided with air outlets.
As a further improvement of the utility model, the hood with the outer diameter smaller than the inner diameter of the hood is nested at the outer side of the hood, and a sealing gasket is arranged at a gap between the lower side of the hood and the air pipe.
As a further improvement of the utility model, the gasket is a graphite gasket.
Compared with the prior art, the utility model has the beneficial effects that:
1. Through setting up connecting portion and installation department, connecting portion and hood integrated into one piece, the connecting rod of connecting portion downside and the screw hole threaded connection of installation department, through the interior hexagonal hole in the connecting portion outside, the hood of dismantling that can be quick can realize the serious hood of quick replacement wearing and tearing condition, need not to demolish tuber pipe and hood simultaneously, has improved production efficiency when saving manufacturing cost.
2. By arranging the connecting part and the connecting rod which are integrally formed with the hood, the sealing gasket is not required to be arranged at the joint of the hood and the air pipe, so that the working steps of readjusting the sealing gasket every time the hood is replaced are reduced, and the time required for maintenance is shortened; and the air tightness of the joint of the hood and the air pipe is improved.

Detailed Description
First embodiment: referring to fig. 1-4, a high security detachable boiler hood comprises an air duct 1 and a hood 2. The hood 2 is arranged on the upper side of the air pipe 1. The hood 2 is of a hollow cover type structure, and a space is reserved in the middle of the hood 2 to accommodate the air pipe 1. The lower side of the hood 2 is integrally provided with a connecting rod 7, the upper end of the connecting rod 7 is fixedly connected with the inner wall of the hood 2, and the connecting rod 7 and the inner wall are integrally formed. The lower end of the connecting rod 7 is provided with external threads.
The upper side of the air duct 1 is fixedly provided with an installation part 9, and in this embodiment, the installation part 9 is welded to the upper side of the air duct 1 or integrally cast, and the installation part 9 protrudes from the upper side of the air duct 1. The screw hole 5 is internally arranged at the upper side of the mounting part 9, and the screw hole 5 is an internal screw hole. The external thread on the connecting rod 7 matches with the internal thread of the threaded hole 5 so that the connecting rod 7 and the mounting portion 9 are screwed.
