Description
Technical field
The utility model is related to a kind of blower mill guiding device in blower mill technical field, specifically relates to
And improvement of the blower mill to raw coal distributor.
Background technology
At present, blower mill is the auxiliary equipment of boiler of power plant, and its main function is the raw coal that will enter boiler in advance
The coal dust of suitable boiler combustion is broken into by hitting, while it also has the dry, ability of pulverized coal conveying.Raw coal is passed through during work
Introduce pipe and fall into coal pulverizer greatly behind the door, slipped into along the slope of deflector in striker wheel, because its drop point concentrates on the one of beater plate
Determine in region, beater plate concentrated wear is serious, cause to safeguard and the replacement cycle is short, the consequence of influence power plant operation.Therefore, develop
It is always new problem anxious to be resolved to develop a kind of blower mill guiding device.
The content of the invention
The purpose of this utility model is to provide a kind of blower mill guiding device, and the utility model can will enter fan
The raw coal one dividing into three of mill, respectively enters three pieces of beater plates at different rates, has three pieces of beater plates in each moment simultaneously
Work, prevents beater plate concentrated wear, improves the service efficiency of beater plate, effectively improve the service life of beater plate.
What the purpose of this utility model was realized in：A kind of blower mill guiding device, including the first diaphragm,
Second diaphragm, bottom plate, the 3rd diaphragm, the 4th diaphragm, gate, bottom support plate, flat board, riser, gusset, the
One diaphragm, the second diaphragm, the 3rd diaphragm, the 4th diaphragm are divided into three-layer set in seal cavity A and big
In door, bottom support plate is connected with seal cavity A seal cavity outer face C, the first diaphragm, the second diaphragm, the
The outside camber line of three diaphragms, the 4th diaphragm and bottom plate is connected with gate medial surface B, and strike is installed on striker wheel E
Plate D, described the first diaphragm, the second diaphragm, the 3rd diaphragm, the 4th diaphragm are respectively by a flat board and one
Riser is welded, and welds in its angle some pieces of gussets；
A kind of described blower mill guiding device cross section is symmetrical three layers of forge piece of step type structure；A kind of described wind
The angle for fanning coal pulverizer guiding device and horizontal plane is 25 °；
Described the first diaphragm, the second diaphragm, the 3rd diaphragm, the 4th diaphragm middle plateform and riser
Material be 16Mn pressboards.
The structure of the present utility model for being characterized by it.Its operation principle is, applied to the guiding device of blower mill,
Including four groups of diaphragms, bottom plate, bottom support plates.Wherein diversion component is divided into three layers, it is upper in two layers respectively by mutually right
The two groups of dividing plates composition claimed, orlop is bottom plate, its outside camber line can with gate and seal cavity inwall is intact agrees with, in welding
Ensure that raw coal will not be leak into the space of deflector bottom afterwards；The other end is vacant state, by the bottom being welded in seal cavity
Portion's supporting plate support.This guiding device can will enter the raw coal one dividing into three of fan mill, and three pieces are respectively enterd at different rates
Beater plate, has three pieces of beater plates to work simultaneously in each moment, prevents beater plate concentrated wear, improves the use effect of beater plate
Rate, so as to effectively improve the service life of beater plate.
A kind of blower mill guiding device compared with prior art, with can by enter fan mill one point of raw coal be
Three, three pieces of beater plates are respectively enterd at different rates, there are three pieces of beater plates to work simultaneously in each moment, are prevented beater plate
Concentrated wear, the service efficiency for improving beater plate, the advantages of effectively improving the service life of beater plate will be widely used in wind
Fan in coal pulverizer technical field.
Brief description of the drawings
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 right view.
Fig. 3 is Fig. 2 F-F sectional views.
Fig. 4 is the structural representation of the blower mill with guiding device.
Fig. 5 is diaphragm part-structure schematic diagram of the present utility model.
Embodiment
Referring to the drawings, a kind of blower mill guiding device, including the first diaphragm 1, the second diaphragm 2, bottom plate
3rd, the 3rd diaphragm 4, the 4th diaphragm 5, gate 6, bottom support plate 7, flat board 8, riser 9, gusset 10, the first water conservancy diversion every
Plate 1, the second diaphragm 2, the 3rd diaphragm 4,5 points of the 4th diaphragm are three-layer set in seal cavity A and gate 6
Interior, bottom support plate 7 is connected with seal cavity A seal cavity outer face C, the first diaphragm 1, the second diaphragm 2,
Three diaphragms 4, the 4th diaphragm 5 are connected with the outside camber line of bottom plate 3 with gate medial surface B, are installed and are beaten on striker wheel E
Hit plate D, described the first diaphragm 1, the second diaphragm 2, the 3rd diaphragm 4, the 4th diaphragm 5 are flat by one respectively
The riser 9 of plate 8 and one is welded, and welds in its angle some pieces of gussets 10.
A kind of described blower mill guiding device cross section is symmetrical three layers of forge piece of step type structure；A kind of described wind
The angle for fanning coal pulverizer guiding device and horizontal plane is 25 °.
Described the first diaphragm 1, the second diaphragm 2, the 3rd diaphragm 4, the middle plateform 8 of the 4th diaphragm 5
Material with riser 9 is 16Mn pressboards.
A kind of workflow of described blower mill guiding device：Raw coal is fallen into behind gate 6, through a kind of described wind
Fan coal pulverizer guiding device is divided into three layers of upper, middle and lower, and it is respectively divided into left and right two parts again with middle level at the middle and upper levels, and raw coal departs from first
It is former because height is different after diaphragm 1, the second diaphragm 2, the 3rd diaphragm 4, the 4th diaphragm 5 and bottom plate 3
The position that coal enters beater plate D is also different, and the usable floor area of beater plate D widths has exceeded 75%, and This prevents beater plate
D concentrated wear, extends beater plate D service life.
K represents raw coal entrance in Fig. 4.
