Detailed description of the invention
Below in conjunction with the accompanying drawings, specific embodiments of the present utility model is described in detail.
As depicted in figs. 1 and 2, suspension type economizer top described in the utility model erecting by overhang, including
Some boatswain chairs 2 to coordinating with economizer bend pipe 1 upper end, boatswain chair 2 is respectively arranged with some openings to
On groove 3, bend pipe 1 upper end hangs in groove 3, is welded with fixed plate 4 between every pair of boatswain chair 2
Fig. 3, Fig. 4, some to connected by cross bar 5 between boatswain chair 2, boatswain chair 2 is provided above at least two
The individual rectangular beam 6 parallel with boatswain chair 2, is connected by transverse slat 7 between adjacent rectangle beam 6, rectangular beam 6
The top of couveuse 8 in economizer.Being provided with some suspension rods 9 on rectangular beam 6, the upper end of suspension rod 9 sets
Being equipped with screw thread, suspension rod 9 upper end is cased with nut 10 respectively after being upward through rectangular beam 6, the lower end of suspension rod 9 is divided
Not being provided with hook 11, the lower end of suspension rod 9 catches on cross bar 5, suspension rod 9 respectively after being passed down through couveuse 8
And it is connected by expansion gear 12 respectively between the upper surface of couveuse 8.
As it is shown in figure 5, described expansion gear 12 includes the fixed cover 13 being welded on suspension rod 9, fixed cover
It is connected by radiation fins 14 between 13 with couveuse 8 upper surface, fixed cover 13, suspension rod 9, radiation fins 14
And it is full of heat-preservation cotton 15 in the cavity formed between couveuse 8 upper surface.
Described groove 3 takes the shape of the letter U, and such boatswain chair 2 and the contact surface arc transition of pressure containing part bend pipe 1, by line
Contact changes face contact into, decreases the outer wall abrasion of bend pipe 1, increases lifting surface area, increase the service life.
The utility model has the advantages that: economizer vertical load is integrated with fixed plate 4 by boatswain chair 2, then
Load is uniformly distributed in as far as possible on every rigid hanger 9, it is to avoid stress is concentrated and caused stressed member to deform.
Suspension rod 9 is designed as round steel manufacture, and lower end arranges hook 11, and top arranges the standard thread of sufficient length；Hang
The corresponding manufacturing process of design of hook 11 is simple, and the uncontrollable factor of Strength co-mputation is few, and the straight section of increase is easy to peace
Dress, suspension rod 9 top is equidistantly fixed on rigid beam by nut 10, and lower end can free wxpansion；Suspension rod 9
There is certain length, the expansion displacement that pressure containing part causes because being heated can be absorbed.The feature of rectangular beam 6 is just
It is antitorque good with stability.In device, when suspension rod 9 is through couveuse 8, installs for convenience and absorb swollen
Swollen displacement, couveuse 8 opening in shell should retain certain space with suspension rod 9 external diameter；The existence in space causes
The leakage of inside smoke, for solving this problem, the link position at suspension rod 9 with couveuse 8 housing adds
Radiation fins 14, inside adds heat-preservation cotton 15.During installation radiation fins about 14 respectively with suspension rod 9 and couveuse 8
Housing seal is welded, and the filling of heat-preservation cotton 15 can efficiently solve gap leakage problem.This kind of expansion gear 12
Heat-proof corrosion resistant performance is good, and sealing effectiveness is effective, and can effectively absorb suspension rod 9 with couveuse 8 housing in fortune
The displacement difference produced during row, it is ensured that boiler safety runs normally.This utility model simple in construction, manufactures work
Skill is simple, good stability, uniform force, installs simple, good seal performance, and expansion structure is reasonable；This
Meet the required necessary requirement that the tube bank of suspension type economizer runs at burner hearth internal security；Bogey is set
Being placed in outside burner hearth, not only reduce operating temperature, it also avoid that flue gas brings washes away and corrodes, significantly
Improve the working environment of spandrel girder, reduce material requirements, moreover it is possible to the service life of extension fixture effectively.
