Abstract
The invention discloses a drying convection wind device for a grinding wheel blank. The drying convection wind device comprises a heating cavity and a convection cavity. An electric heating pipe is arranged in the heating cavity longitudinally. The convection cavity is provided with an air blasting electric fan. Small fans are arranged at four right angle positions of the convection cavity. The four small fans are evenly arranged around the air blasting electric fan. The air blasting electric fan and the small fans are all three-blade electric fans and connected with a stepping motor. The minimum distance between all the small fans and the air blasting electric fan is identical to the minimum distance between all the small fans and the edge of the convection cavity. Two opposite and mutually close faces of the heating cavity and the convection cavity are arranged to be large-hole-diameter iron wire nets. According to the drying convection wind device, the arrangement of the air blasting electric fan and the four small fans overcomes the defect that convection dead angles exist when air blasting is conducted through an original electric fan, hot air circulation in a sintering furnace is formed, thus the inner uniform heating effect is ensured, and the sintering quality of a grinding wheel can be further promoted.
Description
Technical field
The present invention relates to large scale emery wheel production technical field, more particularly, relate to a kind of emery wheel embryo and dry
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 affect the final quality of production of emery wheel and service life.The most general is all to burn in electrical heating furnace chamber
Knot.Even if the electric heating tube in sintering furnace is uniformly arranged, but it is because the matter between each electric heating tube
Amount difference and use difference, each heating effect is not quite similar, and may occur in longer sintering time
The phenomenon that local heating is uneven.It is typically all for the problems referred to above and a drum is set after the heating chamber of sintering furnace
Fan, forms the convector of intracavity, it is possible to play certain even temperature effect.Even if so, because
The side walls of sintering furnace is all planar rectangular, and the blowing face of blowing fan is circular, still can have one in theory
Fixed 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 mill
Wheel embryo dries convection current wind apparatus, it is possible to achieve heat radiation sam effect overall in sintering furnace, promotes the burning of emery wheel embryo
Knot forms quality.
Technical scheme: in order to realize foregoing invention purpose, the technical scheme that this practicality is used is: a kind of emery wheel
Embryo dries convection current wind apparatus, including heating chamber and convection cavity, the described longitudinally disposed electric heating tube of heating intracavity, institute
State convection cavity and air blast electric fan is set.Four right angle of described convection cavity arrange small fan, described 4 small fans
Evenly distributed round the surrounding of air blast electric fan.
Further, described air blast electric fan and little electric fan are three blade electric fans.Described air blast electric fan and little electric fan
It is connected with motor.
Yet 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 is consistent.
Further, described heating chamber and adjacent to each other two of convection cavity are disposed as large aperture ferrum to opposite
Silk screen.
Beneficial effect: compared with prior art, it provides the benefit that in this practicality:
1, this practicality uses an air blast electric fan and the setting of four little electric fans, compensate for an electric fan drum originally
There is the defect at convection current dead angle in wind, forms the hot-air circulation within sintering furnace, it is ensured that internal equal thermal effect,
The sintering quality of emery wheel can be promoted further.
Accompanying drawing explanation
Fig. 1 is that the present invention heats chamber and the structural representation of convection cavity setting.
Fig. 2 is the structural representation that in the present invention, 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 the protection of the present invention
Scope is not limited to described embodiment.
As it is shown in figure 1, a kind of emery wheel embryo dries convection current wind apparatus, including heating chamber 1 and convection cavity 2, described
Longitudinally disposed electric heating tube 3 in heating chamber 1, described convection cavity 2 arranges air blast electric fan 5.
As in figure 2 it is shown, four right angle of described convection cavity 2 arrange small fan 4, described 4 small fans 4
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 fans.
Each little electric fan 4 described is minimum with convection cavity 2 edge with the minimum range of air blast electric fan 5 and each little electric fan 4
Distance is consistent.
Described air blast electric fan 5 and little electric fan 4 are connected with motor.Described heating chamber 1 and convection cavity 2 are mutual
Close two are large aperture wire gauze to opposite 6.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for the common skill of the art
For art personnel, on the premise of without departing from this practical principle, it is also possible to make some improvements and modifications, these
Improvements and modifications also should be regarded as the protection domain of this practicality.
