Abstract
The utility model discloses a squirrel cage type boiler, which comprises a boiler body (10), an air blower (9), a particle feeding auger (1) and a motor (8). A fire door (2) and a slag hole (4) are reserved in the boiler body (10). The top of the boiler body (10) is connected with a flue gas emission pipe (3). The squirrel cage type boiler also comprises at least one cylindrical squirrel cage grate (5). A plurality of squirrel cage grate bars (13) are fixedly arranged between two annular end faces (12) at intervals. A rotating shaft (11) is arranged along the axial direction of each squirrel cage grate (5). The motor drives the squirrel cage grates (5) through a rotating mechanism. Each squirrel cage grate can rotate towards the same direction around the own rotating shaft (11). Air outlets of the air blower (9) are opposite to parts below the squirrel cage grates (5). The squirrel cage type boiler is simple in structure, low in cost and high in fuel utilization efficiency, and can run stably.
Description
Technical field
The utility model relates to a kind of boiler, especially relates to a kind of squirrel-cage boiler.
Background technology
What traditional boiler generally used is fixed fire grate; Owing to receive the restriction of fire grate; Making that boiler is very much harsh to the requirement of fuel, is the serious biomass fuel of coking such as stalk particle and briquetting etc., in fixed furnace grate, just can not use; And can use chain-arranged type fire grate equipment cost in the small-sized biomass boiler uses of the serious biomass fuel of cokings such as stalk particle and briquetting very high, therefore in the small-sized biomass boiler, use seldom.Also have and adopt reciprocating type moving grate, but this fire grate is easier to the phenomenon that occurs getting stuck, makes fire grate not work, and reduces the service efficiency of boiler greatly.
The utility model content
The purpose of the utility model is to provide the squirrel-cage boiler of the serious biomass fuel combustion of cokings such as a kind of suitable stalk particle and briquetting.
For addressing the above problem, the technical scheme that the utility model is taked is:
A kind of squirrel-cage boiler comprises boiler body, air blast; Particulate charge flood dragon and motor have fire door and slag notch on the boiler body, the top connects smoke discharge pipe; It is characterized in that: this squirrel-cage boiler comprises also and is no less than a mouse cage fire grate that said mouse cage fire grate is cylindrical, is fixed between two ring end faces by many fire grate bar five equilibriums; Along mouse cage fire grate axis direction rotating shaft is arranged; Motor drives the mouse cage fire grate through rotating mechanism, and each mouse cage fire grate can be rotationally connected to same side around each axis of rotation, and blower outlet is facing to mouse cage fire grate below.After the charging aperture discharging is burnt to the mouse cage fire grate, the mouse cage fire grate is slowly turned right like this, owing to distance between two adjacent mouse cage fire grates is very little through motor; Make bigger burnt shape waste residue by near all adjacent mouse cage fire grate of mouse cage fire grate transportation of particulate charge flood dragon, finally drop on the slag notch below, less burnt shape waste residue drops on the inclined-plane of boiler body bottom through the slit on the mouse cage fire grate; Finally also landing below slag notch; Meanwhile the back fresh fuel is replenished up, keeps can not having fuel on the fire grate, also can not pile up fuel; Thereby avoid the phenomenon that gets stuck; Force auxiliary air by air blast simultaneously, flameholding is abundant, and the utilization ratio of fuel has also obtained height.
As the further improvement of the utility model, boiler body bottom, mouse cage fire grate below has angle with horizontal plane and is inclined to slag notch, and the burnt shape waste residue in boiler body bottom surface inclination convenient burning back is forced and is discharged to the slag notch below.
Further improvement as the utility model; The even fixed interval of mouse cage fire grate bar is between two ring end faces; Such mouse cage fire grate is not only attractive in appearance, and avoids falling into mouse cage and must not getting rid of owing to some causes at interval greatly granular fuel, causes the air blast effect to be lost efficacy.
As the further improvement of the utility model, transmission mechanism is belt transmission or chain drive, thereby realizes a mouse cage fire grate that driven by motor is all.
In sum, the utility model has the advantages that: simple in structure, cost is low, and is stable, and the utilization ratio of fuel is high.

Fig. 3 is the mouse cage fire grate front view of the utility model boiler.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further explanation.
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model squirrel-cage boiler comprises boiler body 10, air blast 9; Particulate charge flood dragon 1 and motor 8 have fire door 2 and slag notch 4 on the boiler body 10, the top connects smoke discharge pipe 3; This squirrel-cage boiler also comprises mouse cage fire grate 5, and said mouse cage fire grate 5 is cylindrical, by many mouse cage fire grate bars 13 even fixed interval between two ring end faces 12; Along mouse cage fire grate 5 axis directions rotating shaft 11 is arranged; Motor is through the rotating shaft 11 of belt or one of them mouse cage fire grate 5 of chain link, and remaining mouse cage fire grate 5 is arranged with identical direction with very little interval successively, is connected the rotating shaft 11 of every adjacent two mouse cage fire grate 5 the same sides by belt or chain; The coexist inboard or outside of rotating shaft 11 of the belt that connects adjacent mouse cage fire grate 5; Do not disturb mutually when each mouse cage fire grate 5 is rotated, drive when motor rotates with its mouse cage fire grate that directly links to each other 5 and rotate, the mouse cage fire grate 5 of rotation drives the mouse cage fire grate 5 that is adjacent again and rotates towards same direction; The mouse cage fire grate 5 of back is being with successively and is being turned in the same direction, thereby each mouse cage fire grate 5 all can rotate to same side around each axis of rotation 11.Air blast 9 air outlets face mouse cage fire grate 5 belows, and fire grate 5 below boiler bodies 10 bottoms 7 have angle with horizontal plane and are inclined to slag notch 4, form the plane that supplies the particle discarded object landing of burning back.
Open air blast 9 during use to mouse cage fire grate 5 auxiliary airs, biomass fuels such as stalk particle and briquetting are burnt by the mouse cage fire grate 5 in the particulate charge flood dragon 1 input boiler body 10.Little boiler can only adopt a mouse cage fire grate 5, and the particle discarded object after the burning directly is transported to the below of slag notch 4 through the rotation of mouse cage fire grate 5.Bigger boiler can adopt a plurality of mouse cage fire grates 5; Particle discarded object after the burning drives mouse cage fire grate 5 through motor 8 and slowly turns right; Bigger biomass fuel after the burning is transported to another mouse cage fire grate 5 from a mouse cage fire grate 5, finally drops on slag notch 4 belows, less burnt shape waste residue drops on the inclined-plane 7 of boiler body 10 bottoms through the slit on the mouse cage fire grate 5; Finally also landing below slag notch 4; The cleaning of convenient burnt shape waste residue, the back fresh fuel is replenished up simultaneously, keeps the non-interruptible supply of fuel.
