Abstract
The utility model relates to a fuel supply device of a boiler, in particular to a feeding mechanism for a biomass fuel boiler. The feeding mechanism comprises a feeding port and a feeding mechanism, wherein the feeding port is formed in the outer wall of a hearth, and the feeding mechanism is arranged on the feeding port. The feeding mechanism comprises a hopper and a poker, wherein the hopper is fixedly connected to the outer wall of the hearth, and the poker is arranged at the output end of the hopper. The poker comprises a round tubular shell, a rotating shaft and poke plates, wherein the rotating shaft is installed in the shell, and the poke plates are radially and evenly distributed on the rotating shaft. A window is formed in the side wall of the shell and communicated with the output end of the hopper and the feeding port. The rotating shaft is rotatably inserted in the end covers at the two ends of the shell and is in transmission connection with a drive motor through a speed reducer. The feeding mechanism is reasonable in structure and safe and reliable in use; flames in the hearth can be prevented from spreading while continuous feeding is achieved, and therefore the feeding mechanism is suitable for being used for the biomass fuel boiler.
Description
Technical field
The utility model relates to a kind of fuel supply system of boiler, is a kind of biomass fuel boiler feeding mechanism specifically.
Background technology
Existing boiler is all taking high heating value objects such as coal, natural gas, charcoals as fuel.Once adding fuel can work long hours, and does not require continuous feeding.Along with the raising of environmental protection and energy saving consciousness, the straw after employing is pulverized is suppressed the biomass fuel forming becomes one of main fuel of Urban Thermal homogeneous solution-type reactor gradually.Due to biomass fuel self, 1, calorific value is low, consumption is large, needs constantly in burner hearth, to add fuel in combustion process; 2, be not easy to grill thoroughly, be deposited in Central Fuel position together nonflammable, require constantly to center oxygen blast, or constantly stir fuel, it is fully contacted with air.Above-mentioned two features have determined that existing coal-burning boiler cannot use biomass fuel.Biomass fuel boiler require can be continuously to feed in burner hearth, and can not a feed too many.There is a kind of boiler feeds device that adopts auger push type, substantially can realize continuous feeding, but because the burning-point of biomass fuel is low, easy firing, and packing auger propeller couples together the burner hearth of boiler and hopper by hinge in the course of the work, if stove chamber inner combustion is too fierce, be easy to make propagation of flame in hopper, cause the accident.
Summary of the invention
The purpose of this utility model is to provide a kind of characteristic of adapted biomass fuel, rational in infrastructure, safe and reliable, the biomass fuel boiler feeding mechanism of avoiding propagation of flame in burner hearth.
For achieving the above object, the utility model is by the following technical solutions:
Biomass fuel boiler feeding mechanism described in the utility model comprises the charging aperture that is arranged on hearth outer wall, is arranged on the feed mechanism on charging aperture, described feed mechanism comprises the setting gauge that is fixedly connected on hearth outer wall elevating hopper, is arranged on hopper output, described setting gauge comprise circular tube shaped housing, be arranged on the rotating shaft in housing and be evenly distributed on radially the switch-plate in rotating shaft, the sidewall of described housing is provided with the window that is communicated with hopper output and charging aperture; Described rotating shaft is rotatably inserted on the end cap at housing two ends, and rotating shaft is in transmission connection by reductor and drive motors.
Below housing, be provided with the blower that connects air blast, the sidewall of described blower is provided with air port, and described air port is communicated with the window on housing.
Described reductor is turbine worm reducer.
Adopt after technique scheme, this feeding mechanism is rational in infrastructure, safe and reliable, can avoid again propagation of flame in burner hearth in realizing continuous feeding, is applicable to biomass fuel boiler and uses.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
As shown in Figure 1 and Figure 2, biomass fuel boiler feeding mechanism described in the utility model comprises the charging aperture 2 that is arranged on hearth outer wall 1, is arranged on the feed mechanism on charging aperture 2, and feed mechanism is delivered biomass fuel by charging aperture 2 in burner hearth.Described feed mechanism comprises the setting gauge that is fixedly connected on hearth outer wall 1 elevating hopper 3, is arranged on hopper 3 outputs, described setting gauge comprise circular tube shaped housing 4, be arranged on the rotating shaft 5 in housing 4 and be evenly distributed on radially the switch-plate 6 in rotating shaft 5, the quantity of switch-plate 6 can arrange as required, all can for 2-5, these switch-plates 6 on the one hand can be to charging aperture 2 fuel of pulling over, the inner chamber of housing 4 is separated into multiple independently spaces by these switch-plates 6 on the other hand, can avoid flame to spread in hopper 3 by housing 4.The sidewall of described housing 4 is provided with the window that is communicated with hopper 3 outputs and charging aperture 2, as long as the width of window is rationally set, make it cover hopper 3 outputs and charging aperture 2 simultaneously, fuel drops on window from hopper 3, the switch-plate 6 being rotated pushes in charging aperture 2, sends in burner hearth; Described rotating shaft 5 is rotatably inserted on the end cap at housing 4 two ends, and rotating shaft 5 is in transmission connection by reductor 7 and drive motors 8.Described reductor 7 is turbine worm reducer or other forms of larger reduction ratio speed reduction.Drive motors 8 drives rotating shaft 5 and switch-plate 6 slow circumvolves after slowing down by reductor 7, realizes continuous feeding.
In addition, stop up in charging aperture 2 for fear of fuel, be provided with the blower 10 that connects air blast 9 below housing 4, the sidewall of described blower 10 is provided with air port, and described air port is communicated with the window on housing 4.The wind that blower 10 blows out contributes to the conveying of fuel, avoids stopping up charging aperture 2.
When use, biomass fuel is stored in hopper 3, starts drive motors 8 and air blast, fuel is transported to charging aperture 2 from hopper 3 through the effect of switch-plate 6 and blower 10 and sends into burner hearth.
