Abstract
The utility model discloses a kind of emery wheel embryo and dry convection current wind apparatus, comprise heating chamber and convection cavity, longitudinally arrange electric heating tube in described heating chamber, described convection cavity arranges air blast electric fan.Four right angle of described convection cavity arrange small fan, and described 4 small fans are evenly distributed round the surrounding of air blast electric fan.Described air blast electric fan and little electric fan are Three-blade electric fan.Described air blast electric fan is connected with stepper motor with little electric fan.The minimum range of each little electric fan described and air blast electric fan and each little electric fan and convection cavity edge minimum range consistent.Described heating chamber and adjacent to each other two of convection cavity are all set to large aperture wire netting to opposite.This practicality adopts the setting of an air blast electric fan and four little electric fans, compensate for the defect that script electric fan air blast exists convection current dead angle, form the hot air circulate of sintering furnace inside, ensure that inner equal thermal effect, the sintering quality of emery wheel can be promoted further.
Description
Technical field
The utility model relates to large scale emery wheel production technical field, more particularly, relates to a kind of emery wheel embryo and dries convection current wind apparatus.
Background technology
During emery wheel manufactures, sintering is an important operation, and the temperature of sintering controls, and duration controls all directly to affect the final quality of production of emery wheel and service life.General is all sinter in electrical heating furnace chamber at present.Even if evenly arrange the electric heating tube in sintering furnace, but because the mass discrepancy between each electric heating tube and usage variance, each heating effect is not quite similar, and the phenomenon of local heating's inequality may occur in longer sintering time.Be all generally that a blower fan is set after the heating chamber of sintering furnace for the problems referred to above, form the convector in chamber, certain even temperature effect can be played.Even if like this, because the side walls of sintering furnace is all planar rectangular, and the blowing face of blower fan is circular, in theory or can there is certain heat radiation dead angle, causes emery wheel embryo to be sintered to be heated inequality, affects quality.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant, through repeatedly putting into practice improvement, devises a kind of emery wheel embryo and dries convection current wind apparatus, can realize heat radiation sam effect overall in sintering furnace, and the sintering promoting emery wheel embryo forms quality.
Technical scheme: in order to realize foregoing invention object, the technical scheme that this practicality adopts is: a kind of emery wheel embryo dries convection current wind apparatus, comprises heating chamber and convection cavity, longitudinally arrange electric heating tube in described heating chamber, described convection cavity arranges air blast electric fan.Four right angle of described convection cavity arrange small fan, and described 4 small fans are evenly distributed round the surrounding of air blast electric fan.
Further, described air blast electric fan and little electric fan are Three-blade electric fan.Described air blast electric fan is connected with stepper motor with little electric fan.
Again further, the minimum range of each little electric fan described and air blast electric fan and each little electric fan and convection cavity edge minimum range consistent.
Further, described heating chamber and adjacent to each other two of convection cavity are all set to large aperture wire netting to opposite.
Beneficial effect: compared with prior art, its beneficial effect is in this practicality:
1, this practicality adopts the setting of an air blast electric fan and four little electric fans, compensate for the defect that script electric fan air blast exists convection current dead angle, form the hot air circulate of sintering furnace inside, ensure that inner equal thermal effect, the sintering quality of emery wheel can be promoted further.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model heating chamber and convection cavity are arranged.
Fig. 2 is the structural representation that in the utility model, in convection cavity, electric fan is arranged.
Detailed description of the invention
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of emery wheel embryo dries convection current wind apparatus, comprises heating chamber 1 and convection cavity 2, and longitudinally arrange electric heating tube 3 in described heating chamber 1, described convection cavity 2 arranges air blast electric fan 5.
As shown in Figure 2, four right angle of described convection cavity 2 arrange small fan 4, and described 4 small fans 4 are evenly distributed round the surrounding of air blast electric fan 5.Described air blast electric fan 5 and little electric fan 4 are Three-blade electric fan.Each little electric fan 4 described is consistent with convection cavity 2 edge minimum range with each little electric fan 4 with the minimum range of air blast electric fan 5.
Described air blast electric fan 5 is connected with stepper motor with little electric fan 4.Described heating chamber 1 and adjacent to each other two of convection cavity 2 are large aperture wire netting to opposite 6.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from this practical principle, can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of this practicality.
