Abstract
The utility model discloses a kind of powdered coal burner coal feed points, including coal feed point main body, coal feed point main body is equipped with air inlet, bottom plate and side plate, and air inlet is obliquely installed upwards in 15 °, bottom plate position is equipped with bottom wear-resistant liner, and side plate position is equipped with side wear-resistant liner.The utility model powdered coal burner coal feed point, air inlet reduce wind-force directly washing away to bottom plate in tilting 15 ° upwards;At bottom plate and side plate increased high alloy wear-resistance liner plate can increase export place it is anti-wear can, and liner plate is fixed by bolts, replacement easy to disassemble;The cooperation of both the above technical solution can improve the service life of entire coal feed point, substantially reduce maintenance cost.
Description
Technical field
The utility model is related to powdered coal burner technical field, specifically a kind of powdered coal burner coal feed point.
Background technology
Powdered coal burner refers to that coal dust is allowed fully to burn in a short time, the equipment for generating high temperature eddy current.According to
On the way, coal burner is divided into:1, the special coal burner of rotary kiln;2, steam coal powder burner;3, asphalt blending station is special
Coal burner.
In the production practices of circulating fluidized bed boiler, at the coal feed point of circulating fluidized bed boiler, coal dust is fallen from top,
It is blown into burner hearth via the wind-force of air inlet, is burnt.Due to being acted on while coal dust and wind-force, mill is generated to exit
Damage, if not enough wear strengths, it is easier to be worn, deform, maintenance difficult, service life is short, only some months.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, solve presently, there are technology lack
It falls into, the utility model provides a kind of powdered coal burner coal feed point.
Technical solution used by the utility model is:
A kind of powdered coal burner coal feed point, including coal feed point main body, the coal feed point main body be equipped with air inlet, bottom plate and
Side plate, the air inlet are obliquely installed upwards in 15 °, and the bottom plate position is equipped with bottom wear-resistant liner, the side plate position
Side wear-resistant liner is installed.
Further, the bottom wear-resistant liner is fixedly connected with lower portion bolt, the side wear-resistant liner and side
Facial position bolt is fixedly connected, and is fixed by bolts connection, replacement easy to repair.
Preferably, the bottom wear-resistant liner and the side wear-resistant liner are high alloy wear-resistance liner plate, use
High alloy wear-resistance liner plate makes direct impact and friction of the exit from material, the anti-wear energy at the place that increases export.
Preferably, the thickness of the bottom wear-resistant liner is more than the thickness of the side wear-resistant liner.
The utility model has the beneficial effects that:A kind of powdered coal burner coal feed point disclosed by the utility model, air inlet are in
15 ° are tilted upwards, reduce wind-force directly washing away to bottom plate;
At bottom plate and side plate increased high alloy wear-resistance liner plate can increase export place it is anti-wear can, and liner plate is adopted
It is fixed with bolt, replacement easy to disassemble;
The cooperation of both the above technical solution can improve the service life of entire coal feed point, substantially reduce maintenance cost.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model powdered coal burner coal feed point.
Fig. 2 is the main structure diagram of the utility model powdered coal burner coal feed point.
Fig. 3 is the schematic cross-sectional view in the faces A-A in Fig. 2.
In figure, the 1- coal feed points bottoms the main body 2- air inlet 3- sides wear-resistant liner 4- wear-resistant liner.
Specific implementation mode
In order to deepen the understanding to the utility model, the utility model is made with reference to the accompanying drawings and examples further detailed
Thin explanation.Following embodiment is only used for clearly illustrating the technical solution of the utility model, and cannot be limited with this
The scope of protection of the utility model.
As shown in Figs. 1-3, the utility model powdered coal burner coal feed point, including coal feed point main body 1, in coal feed point main body 1
Equipped with air inlet 2, bottom plate and side plate, air inlet 2 is obliquely installed upwards in 15 °, and bottom plate position is equipped with bottom wear-resistant liner 3,
Side plate position is equipped with side wear-resistant liner 4.
In the present embodiment, bottom wear-resistant liner 3 is fixedly connected with lower portion bolt, side wear-resistant liner 4 and side surface part
Position bolt is fixedly connected, and is fixed by bolts connection, replacement easy to repair.
In the present embodiment, bottom wear-resistant liner 3 and side wear-resistant liner 4 are high alloy wear-resistance liner plate, using high alloy
Wear-resistant liner makes direct impact and friction of the exit from material, the anti-wear energy at the place that increases export.
In the present embodiment, the thickness of bottom wear-resistant liner is more than the thickness of side wear-resistant liner, under normal circumstances, bottom plate by
To the impact force bigger of coal dust, therefore, the thickness of bottom wear-resistant liner is greater than the thickness of side wear-resistant liner.
As shown in figure 3, air inlet in tilting 15 ° upwards, reduces wind-force directly washing away to bottom plate.
The specific work process of the utility model powdered coal burner coal feed point is:At powdered coal burner coal feed point, due to
The air inlet of original powdered coal burner coal feed point is all parallel with horizontal plane, generates to bottom plate and directly impacts, now by air inlet
It is set as tilting 15 ° upwards, reduces wind-force directly washing away to bottom plate;In addition high alloy is installed in the inner wall of bottom plate and side plate
Wear-resistant liner increases the anti-wear energy in exit.
It is noted that embodiment described above is to the illustrative and not limiting of technical solutions of the utility model, affiliated skill
The equivalent replacement of art field those of ordinary skill or other modifications made according to the prior art, as long as it is new not exceed this practicality
The thinking and range of type technical solution, should be included within the interest field required by the utility model.
