Description
Technical field：
The invention belongs to biomass energyizatioies to utilize technical field, more particularly to a kind of control air-flow flowing side
To mechanism and application the mechanism biomass combustion machine.
Background technology：
Existing biomass burner all has biomass feeding structure, by the mechanism by the biological particles in feed bin
It is sent into combustion chamber, traditional biomass feeding mechanism is using screw propulsion conveying mechanism I, the biomass in feed bin 1
Grain is pushed to by the screw propulsion conveying mechanism I in combustion chamber after 2 attrition crushing of spiral blanking machine to burn, but
Inventor has found that the screw propulsion conveying mechanism I often occurs biological particles and falls into inside it in actual use
The case where being blocked in spiral, and then lead to biomass burner cisco unity malfunction, hinder production to be carried out continuously, failure rate
Height increases maintenance cost and operating cost.
Invention content：
The purpose of the present invention is in view of the deficiencies of the prior art, providing a kind of mechanism of control air current flow direction,
The mechanism forms an enclosure space by two cylinders setting up and down and positioned at the sleeve of cylindrical outer, and two cylinders pass through
The mode that corresponding chamfering is arranged forms an annular opening, and the direction of the annular opening is direction obliquely；Air-flow is opened through the annular
Air velocity improves after mouthful, and unanimously oblique lower section, the direction of air-flow are controlled in direction, while the impulse force of air-flow improves.
The technology solution of the present invention is as follows：
It is a kind of control air current flow direction mechanism, including cylinder and be set to cylinder outer wall and with the cylinder formation one
The sleeve of enclosure space, the cylinder include the first cylinder section and the second cylinder section two sections, and the two is coaxially set, described
There are a distances between the first cylinder section and the second cylinder section；The first cylinder section is outside the end of the second cylinder section
Wall is offered with the outer chamfer that gradient is A；The second cylinder section is offered close to the inner wall at end of the first cylinder section to be had
Gradient is the inner chamfer of B, the first cylinder section and described the second cylinder one annular opening of intersegmental formation；The sleeve offers
Airflow inlet, gas supply stream enter in the enclosure space；Air-flow is after flowing into mouth and entering in the enclosure space by annular
Opening flows downward out after being expelled in the second cylinder section along the second cylinder section inner cylinder.
The beneficial effects of the present invention are：
(1) by annular opening, the direction of air-flow can only be flowed out by control along the direction of annular opening, the speed of air-flow
Increase, at the same time its orientation consistency enhances, and impact force increases.
(2) mechanism is made of two cylindrical sections, one section of sleeve, and cylinder correspondence opens up chamfering, rear to carry out assembly welding,
Its is simple in structure, and manufacture craft is convenient, simple and practical and at low cost.
As an implementation, the gradient A is 30-60 degree.This angle is more advantageous to introducing air-flow at this time.
As an implementation, the gradient B is equal with the numerical value of gradient A.When the two is equal, annular is opened
Mouth orientation consistency is high, can more improve the percent of pass of air-flow.
As another embodiment, the overall diameter of the first cylinder section 4 is D1, the overall diameter of the second cylinder section
For D2, D1=(0.6-0.8) * D2.At this point, the overall diameter of the first cylinder section is less than the overall diameter of the second cylinder section, increase
The single air-flow throughput of annular opening, is applicable to the larger occasion of air-flow throughput.
As another embodiment, the first cylinder section is connected with the offer telescopic screw, and the first cylinder can lead to
Cross the relative position that rotation changes itself and the sleeve.The relative position that can adjust the sleeve by rotating the first cylinder, into
And the distance between two cylindrical sections can be adjusted, when the distance of the first cylinder and the second cylinder increases, annular opening is opened
Mouth increases, and throughput is increased by speed；Conversely, then opposite；It is applicable to different use occasions.
As another embodiment, the air-flow is provided by wind turbine.
It is another object of the present invention in view of the deficiencies of the prior art, provide a kind of biomass combustion machine.The present invention
Technology solution it is as follows：
It is connected to the feed screw of setting below a kind of biomass combustion machine, including feed bin, feed bin, goes out with feed screw
The feeding passage that mouth end is connected, being connected in the combustion chamber for the feeding passage are additionally provided with bocca on the combustion chamber,
Its special feature is to include the mechanism and wind regime of control air current flow direction described above, the control air current flow direction
Mechanism is set between the feed screw outlet end and the feeding passage；Biomass after feed screw is sheared
Grain enters in the cylinder, and wind regime introduces to be blown by the annular opening and is sent into biological particles in combustion chamber by feeding passage
Burning.
The wind regime provides for wind turbine as a preferred implementation manner,.
The biomass combustion machine eliminates the screw propulsion conveying mechanism of traditional biomass feeding mechanism, is sent by adding
Wind mechanism makes biological particles quickly be entered in combustion chamber by feeding passage under the push of the air-flow of wind pushing mechanism, increases life
Mobility of the material grains in feeding-passage, the problem of avoiding biological particles accumulated plugging.
The beneficial effects of the present invention are：
(1) present invention eliminates screw propulsion conveying mechanisms, are sent into biological particles by the form that air-flow pushes and fire
Room is burnt, solves the problems, such as the easy blocking screw conveyer of biological particles, it is simple in structure, it is easy to use, and can prevent from firing
It burns indoor fire to be back in feed bin, that is, prevents the generation of tempering phenomenon.
(2) size of the annular opening of the mechanism can be adjusted into accommodating adjusting according to actual use demand
It is whole, it is adaptable.
