Abstract
The utility model relates to a biomass chain grate boiler, in particular to a biomass pressing block feeding mechanism of a biomass chain grate boiler. The biomass pressing block feeding mechanism comprises a hopper and a chain grate. A front wall is arranged beside the hopper. A hollow cone-shaped feeding path is connected below the hopper. The lower end of the feeding path extends to the position above the chain grate. A switch device which enables the feeding path and the hopper to be connected or disconnected is arranged at the connecting position of the hopper and the feeding path. According to the biomass pressing block feeding mechanism, the connecting or disconnecting state of the feeding path and the hopper is controlled through the switch device, the feeding channel is placed between a material bin and a material blocking plate, the distance between the material bin and the material blocking plate is long, and accordingly material bin igniting is effectively avoided. The biomass pressing block feeding mechanism is simple in structure, low in cost and convenient to operate.
Description
Technical field
The utility model relates to the biomass block feeder of a kind of living beings chain-grate boiler, particularly a kind of living beings chain-grate boiler.
Background technology
Change production of energy and consumption pattern; develop biomass energy etc. and there is environmental friendliness, the clean energy resource resource that renewable and resource is very abundant; be solution CNPC, coal shortage, set up continuable energy resource system; ensure national energy security; preserve the ecological environment, improve the main strategic measure of China's sustainable development capacity.Therefore, change production of energy and consumption pattern, develop the reproducible clean energy resource resources such as biomass energy to setting up continuable energy resource system, promote national economic development and be significant with environmental protection.The utilization of biomass energy at present has three kinds of technology such as gasification of biomass, liquefaction, direct burning, all has certain technical barrier.Gasification, liquefaction technology are to say living beings through multiple conversions and purify to burn afterwards again, and intermediate link has not only improved investment operating cost, has also reduced total utilization ratio of biomass energy.And gasification, liquefied fuel calorific value are low, technical also need the such as stable operation, tar removing, gas purification, improve; And direct combustion technical efficiency is higher, and the secondary pollution problem that does not have tar to bring, so comparatively speaking, direct combustion technical efficiency is higher, and the secondary pollution problem that does not have tar to bring, so comparatively speaking, the advantage of direct combustion is obvious.
At present, the feeder of the boiler of domestic most of biomass briquette burnings is all directly to expecting on traveling-grate stoker by reverse taper hopper, the end of reverse taper hopper is furnished with a fan-shaped striker plate, when boiler does not need charging, striker plate does not rotate reverse taper hopper bottom is sealed, and stops feed.But the feeder of current domestic biomass block boiler has a lot of shortcomings, such as: bin bottom from coal sluice gate close to, coal sluice gate strile-backs and easily burns out front wall, the hidden danger of the feed bin that ignites in addition.
Summary of the invention
The utility model technical issues that need to address are to provide and a kind ofly prevent that coal sluice gate from burning out front wall, the biomass block feeder of the feed bin that ignites.
For solving above-mentioned technical problem, a kind of biomass block feeder of the utility model, comprises hopper and traveling-grate stoker, the other front wall that is provided with of described hopper, described hopper below is connected with hollow taper feed path, and lower end, described feed path extends to traveling-grate stoker top; The junction in described hopper and feed path is provided with and makes feed path and hopper in conducting or cut off state of switch device.
Further, described switching device is to material roller, describedly to material roller, is fixed in the rotating shaft through hopper, and described giving in material roller is provided with a minute root piece.
Further, within described minute, root piece is totally four, is evenly distributed on the export-oriented circumference of rotating shaft.
Further, described switching device is screw rod, and described screw rod is vertically arranged on the junction in hopper and feed path, and the diameter of described screw rod and junction diameter adapt.
Further, described front wall lower end is fixed with striker plate near a side of hopper.
Adopt after said structure, control the state of feed path and hopper conducting or partition by switching device, feed path is between feed bin and striker plate, and feed bin and striker plate distant, can effectively prevent that feed bin from igniting like this.The utility model is simple in structure, and cost is low, easy to operate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model the first embodiment.
Fig. 2 is the structural representation of screw rod in the utility model the second embodiment.
In figure: 1 is hopper, 2 is feed path, and 3 is front wall, and 4 is traveling-grate stoker, and 5 is to material roller, and 6 is rotating shaft, and 7 is a minute root piece, and 8 is striker plate
The specific embodiment
Embodiment one:
As shown in Figure 1, a kind of biomass block feeder of the present utility model, comprises hopper 1 and traveling-grate stoker 4, the other front wall 3 that is provided with of described hopper 1.Described hopper 1 below is connected with hollow taper feed path 2, and 2 lower ends, described feed path extend to traveling-grate stoker 4 tops; Briquette-fuel falls in hopper 1 like this, drops on traveling-grate stoker 4, and then by traveling-grate stoker, send into combustion zone and burn after the guiding of feed path 2.The junction in described hopper and feed path is provided with and makes feed path and hopper in conducting or cut off state of switch device.
Here the switching device that embodiment one adopts is to material roller 5, and the described material roller 5 of giving is fixed in the rotating shaft 6 through hopper, and described giving in material roller 5 is provided with minute root piece 7.Within described minute, root piece 7 is totally four, is evenly distributed on the export-oriented circumference of rotating shaft 6.Like this, along with giving the rotation of material roller 5, the briquette-fuel between minute root piece 7 is fallen on traveling-grate stoker 4 along feed path 2.By making the state in conducting and partition between feed path and hopper to the rotation of material roller 5, just need to carry to drive to material roller 5 and rotate by rotating shaft 6 like this; In the time will preventing from igniting feed bin, just stop rotating shaft 6 and rotate, cut off feed path and hopper.
Further, for the briquette-fuel that makes to fall on traveling-grate stoker 4 is scattered evenly, described front wall lower end is fixed with striker plate near a side of hopper.
Embodiment two:
Embodiment one is identical with other places of embodiment two, and different places is that described switching device is screw rod, and as shown in Figure 2, described screw rod is vertically arranged on the junction in hopper and feed path, and the diameter of described screw rod and junction diameter adapt.Like this, when bolt rotary, the briquette-fuel in hopper will be along with the rotation of screw rod be from dropping in feed path between screw flight groove; In the time will preventing from igniting feed bin, just stop bolt rotary, cut off feed path and hopper.
Certainly, the utility model also can magnetic valve or other applicable switching devices, within such conversion all drops on protection domain of the present utility model.
