Abstract
The utility model discloses an air flue reinforcing device of a blast furnace dust removing fan, which belongs to the technical field of blast furnace dust removing equipment repairing, for reinforcing an inlet air flue and an outlet air flue of the blast furnace dust removing fan. According to the technical scheme, the device comprises a hollow shaft and a baffle, wherein the hollow shaft is a cylinder which penetrates through two side walls of the air flues in a perpendicular manner in the horizontal direction; the axis of the hollow shaft is perpendicular to longitudinal shafts of the air flues and is parallel to the upper top surfaces of the air flues; baffles are connected to two ends of the hollow shaft; the baffles are connected with the outer walls of the two side walls of the air flues in a welded manner. Due to additional arrangement of the hollow shaft on the air flues, the hollow shaft is solidly connected with the air flues through the baffles, then a support function is achieved for the walls of the air flues through the hollow shaft, the strength of the air flues is improved, the vibration amplitude of the air flues is greatly reduced, and the safe and reliable operation of the dust removing fan is ensured. The device is simple in structure and remarkable in effect, the great amplitude vibration of the inlet air flue and the outlet air flue of the dust removing fan is effectively eliminated, the vibration noise is eliminated, and the service life of each flue is prolonged.
Description
Technical field
The utility model relates to a kind of to the import air channel of blast furnace dedusting blower fan and the device that outlet air channel reinforces, and belongs to blast furnace dedusting equipment Repairing Technology field.
Background technology
Blast furnace dedusting blower fan comprises casting house dedusting fan and ore deposit groove dedusting fan, the Main Function of casting house dedusting fan is to remove the flue dust and the obnoxious flavour that in blast furnace casting production process, produce, and the Main Function of ore deposit groove dedusting fan is to remove the dust producing in blast furnace burden screening, transport process.Because blast furnace dedusting is larger with blower fan processing air quantity, 2000m
3level blast furnace is generally at 600000m
3/ h left and right, 3200m
3this numerical value of the above blast furnace of level is larger, has determined that thus the duct dimension of blast furnace dedusting blower fan wants enough large, to meet the air quantity demand of fly-ash separator, reaches dust removing effects.
The import air channel of general dedusting fan and outlet air channel are generally oblong channels structure, and import air channel is that set up in high-altitude, also need according to the mounting height of fly-ash separator and with the spacing of blower fan, setting party's elbow carries out transition.Dedusting fan outlet air channel without factory building is generally shorter, is directly connected with chimney; The dedusting fan outlet air channel of installing in factory building is slightly long, the length depending on factory building exterior wall apart from dedusting fan outlet, and generally ground proximity setting, is connected with chimney after going out factory building.Because the size in the import air channel of dedusting fan and outlet air channel is larger, length is longer, in the time of dedusting fan running work, wheel rotation steadily or the situation such as leak out in air channel all can cause the great vibrations in air channel.For eliminating the vibration in air channel, except to reinforcing between air channel and its brace foundation, be also necessary to take measures to improve the intensity in air channel self.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of air channel bracing means of blast furnace dedusting blower fan, and this bracing means can improve self intensity in blast furnace dedusting blower fan import air channel and outlet air channel, to eliminate the vibration in air channel.
The technical scheme solving the problems of the technologies described above is:
A kind of blast furnace dedusting fan air channel bracing means, it comprises tubular shaft and baffle plate, tubular shaft is cylinder, along continuous straight runs vertically passes the two side in air channel, the axis of tubular shaft is vertical with the longitudinal axis in air channel, and parallel with the upper end face in air channel, the two ends of tubular shaft connect baffle plate, and the outer wall of baffle plate and two side, air channel is welded to connect.
Above-mentioned blast furnace dedusting fan air channel bracing means, there is stiffening web in described baffle plate outside, and stiffening web is vertical with baffle plate plate face, and the dual-side of stiffening web is welded to connect with tubular shaft outer wall and baffle plate outer panel face respectively.
The beneficial effects of the utility model are:
The utility model has increased tubular shaft on air channel, and tubular shaft is connected firmly by baffle plate and air channel, and tubular shaft has played supporting role to wind path wall, has improved the intensity in air channel, greatly reduces its Oscillation Amplitude, has ensured the safe and reliable operation of dedusting fan.The utility model is simple in structure, successful, has effectively eliminated the violent oscillatory motion in dedusting fan import air channel and outlet air channel, has eliminated vibrating noise, has extended the work-ing life in air channel.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side-view of Fig. 1.
In figure, mark is as follows: air channel 1, tubular shaft 2, baffle plate 3, stiffening web 4.
Embodiment
The utility model has increased tubular shaft 2 and baffle plate 3 on air channel 1, has improved the intensity in air channel 1, greatly reduces its Oscillation Amplitude.
In figure, show, tubular shaft 2 is cylinder, is cut into by thick-walled seamless steel pipes.Tubular shaft 2 along continuous straight runs are vertically through the two side in air channel 1, and the axis of tubular shaft 2 is vertical with the longitudinal axis in air channel 1, and parallel with the upper end face in air channel 1.
When tubular shaft 2 is installed, on 1 two side, air channel, use gas cutting perforate, the hole on two side will ensure that concentricity deviation is not more than 5mm, and aperture is slightly larger than the external diameter of tubular shaft 2, tubular shaft 2 is passed to two holes, and stop surplus outward at air channel 1 sidewall.
In figure, show, the two ends of tubular shaft 2 connect baffle plate 3, and baffle plate 3 is welded to connect with the outer wall of 1 two side, air channel.
An embodiment of the present utility model adopts foursquare baffle plate 3, baffle plate 3 has centre hole, the centre hole of baffle plate 3 is enclosed within on tubular shaft 2 and is close to the outer wall in air channel 1, be weldingly connected along the circumference of baffle plate 3 centre holes and the outer wall of tubular shaft 2, and a diagonal lines of baffle plate 3 is overlapped with the longitudinal axis of tubular shaft 2.Four limits of baffle plate 3 and the outer wall in air channel 1 are weldingly connected.
In figure, show, there is stiffening web 4 in baffle plate 3 outsides, and stiffening web 4 is vertical with baffle plate 3 plate faces, and the dual-side of stiffening web 4 is welded to connect with tubular shaft 2 outer walls and baffle plate 3 outer panel faces respectively.
