Description
Technical field
The utility model relates to ventilation equipment technical field, particularly relates to a kind of fire-protection high temp inside that is arranged on for wrapping up the inner tube structure of motor.
Background technique
Smoke exhaust fan inner core of the prior art is fixed on fire-protection high temp inside, motor is arranged on smoke exhaust fan inner core, in order to ensure the stability of motor rotation, the outer wall of smoke exhaust fan inner core is provided with multiple radiation hole, and radiation hole is made by punching on the outer wall of smoke exhaust fan inner core, and is covered with protective housing outside punching place, protective housing is made by multiple metal sheet welding, complex manufacturing technology, consumable quantity is large, adds the manufacture cost of fire-protection high temp.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides the smoke exhaust fan inner core that a kind of radiation hole can be one time punching molded, reasonable in design, and preparation process is simple, reduces consumptive material and cost of production.
The utility model solves the technological scheme that its technical problem adopts: a kind of smoke exhaust fan inner core, be made up of the shell of tubular structure, shell both sides are opening, a flange plate is provided with in the opening of shell side, the open outer side of the shell the other end is covered with a lid, described side wall of outer shell is provided with some radiation holes, it is characterized in that: described radiation hole is one perpendicular to the strip opening of described shell longitudinal center line, and radiation hole prolongs its length direction both sides and is respectively equipped with the first one time punching molded punch section and the second punch section.
The first described punch section and the second punch section are respectively to inside side wall of outer shell or outside inclination 10-45 degree.
The first described punch section or the second punch section seamlessly transit to side wall of outer shell centered by the mid point near radiation hole side.
Described radiation hole circlewise structural distribution in the side of shell near flange plate.
The beneficial effects of the utility model are:
1, reasonable in design, preparation process is simple, it is one time punching molded that first punch section of radiation hole both sides and the second punch section pass through mould, seamlessly transitting to side wall of outer shell centered by the mid point near radiation hole side of first punch section and the second punch section, constitute the operator guards of radiation hole, simultaneously compared with the radiation hole of original structure on consumptive material without the need to extra auxiliary material, artificial link also eliminates punching, welding procedure, reduces cost of production;
After the radiation hole architecture advances of 2, smoke exhaust fan inner core, significantly can reduce the resistance of air in equipment running process, improve the working efficiency of smoke exhaust fan.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model;
Fig. 3 is the partial structurtes schematic diagram of radiation hole;
In figure: 1 shell, 2 radiation holes, 3 first punch sections, 4 second punch sections, 5 lids, 6 bolts, 7 flange plate.
Embodiment
As Fig. 1, shown in 2: a kind of smoke exhaust fan inner core, be made up of the shell 1 of tubular structure, shell 1 both sides are opening, a flange plate 7 is provided with in the opening of shell 1 side, flange plate 7 is arranged on opening inner side and is welded and fixed, installation for motor is fixed, the open outer side of shell 1 the other end is covered with a lid 5, lid 5 is connected and fixed by bolt 6 and shell 1, for carrying out seal protection to shell 1, described shell 1 sidewall is provided with some radiation holes 2, radiation hole 2 circlewise structural distribution in the side of shell 1 near flange plate 7, and the opening of radiation hole 2 is towards identical with the direction of smoke exhaust fan smoking, wherein:
Described radiation hole 2 is one perpendicular to the strip opening of described shell 1 longitudinal center line, and radiation hole 2 prolongs its length direction both sides and is respectively equipped with the first one time punching molded punch section 3 and the second punch section 4;
The first described punch section 3 tilts 20 degree to shell 1 side-wall outer side, and the second punch section 4 tilts 20 degree to shell 1 inside sidewalls;
As shown in Figure 3: the first described punch section 3 and the second punch section 4 all by near radiation hole 2 side mid point centered by the transition of shell 1 smooth-sided, for the first punch section 3, first punch section 3 is centered by the mid point A near radiation hole 2 side, seamlessly transit respectively to some B, the some C of the first punch section 3 and shell 1 sidewall intersection, some D, some E and some F, make the first punch section 3 and the second punch section 4 surface smoothing, significantly can reduce the resistance of air in equipment running process, improve the working efficiency of smoke exhaust fan;
Above-mentioned smoke exhaust fan inner tube structure is reasonable in design; preparation process is simple; it is one time punching molded that first punch section 3 of radiation hole 2 both sides and the second punch section 4 pass through mould; first punch section 3 and the second punch section 4 constitute the operator guards of radiation hole 2; simultaneously compared with the radiation hole 2 of original structure on consumptive material without the need to extra auxiliary material; artificial link also eliminates punching, welding procedure, reduces cost of production.
The foregoing is only preferred embodiments of the present utility model, as long as realize the purpose of this utility model technological scheme with basic same approach, all belong within protection domain of the present utility model.
