Abstract
The utility model discloses a single-roller layered coal hopper which comprises a coal hopper shell (1), wherein the upper part of the coal hopper shell (1) is provided with a feed inlet (2), and the lower part of the coal hopper (1) is provided with a screening device (3) and a discharge hole. The single-roller layered coal hopper is characterized in that a coal poking roller (5) is arranged in the coal hopper shell (1) below the feed inlet (2), and a plurality of uniformly distributed coal poking strips (6) are arranged along the axial direction of the coal poking roller (5); an arc plate (7) with one end connected with the coal hopper shell (1) is arranged below the coal poking roller (5); in the poking direction of the coal poking roller (5), a coal poking outlet (8) is arranged between the arc plate (7) and the coal hopper shell (1); and the coal poking outlet (8) is positioned above the screening device (3). The single-roller layered coal hopper has the advantages of simple structure, artful design, guarantee of the fuel coal layering effect and improvement of the boiler heat efficiency, and a shed coal phenomenon is fundamentally avoided.
Description
Technical field
The utility model relates to a kind of coal bunker, particularly a kind of single rod layering coal bunker.
Background technology
At present, just changeing chained coal fired boiler and adopting layering coal supply apparatus (being coal bunker) mostly, adopt this equipment after; Can let fire coal be able to loosen,, reach the purpose that improves the thermal efficiency through improving burning condition; Make the user obtain certain economic benefits, but be two roll-to-roll structures, also have some problems in actual use: at first at traditional coal bunker; Behind the coal-fired entering coal bunker, can down flow automatically from the top of coal moving roller, can cause the thickness height in coal seam on the fire grate uneven like this because of deadweight; If fire coal is moist or bulk is arranged, it is coal-fired that coal moving roller just is difficult to effectively dial-out, thereby lose the meaning of stratified combustion; Secondly, be the cloth coal mode that small coal occupied under coarse coal occupied to the coal seam, when using low calorific value coal; Because grate wind chamber is to give wind from bottom to top; Reduce the ignition temperature of coal bottom, can make insufficient just the entering in the slag remover of part lump coal burning, caused the phosphorus content of slag to increase; Simultaneously,, often have the coal cinder of freezing to occur, thereby these freeze coal cinder and can revolve that floating over skids on the coal roller causes canopy coal phenomenon for the fire coal of north of china in winter.Therefore need a kind of novel coal bunker that can solve above-mentioned variety of problems now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, can guarantee coal-fired layered effect, improves boiler thermal output, fundamentally avoids single roller layering coal bunker of canopy coal phenomenon.
The technical solution of the utility model is: a kind of single roller layering coal bunker; Comprise coal bunker housing 1; Be provided with charging aperture 2 on the top of coal bunker housing 1, the bottom of coal bunker housing 1 is provided with screening plant 3 and discharging opening, it is characterized in that: be provided with coal moving roller 5 in the coal bunker housing 1 of described charging aperture 2 belows; Along a plurality of equally distributed group of coal bars 6 of axially being provided with of coal moving roller 5; Below coal moving roller 5, be provided with the arc 7 that an end links to each other with coal bunker housing 1, on the dial-out direction of coal moving roller 5, have one between arc 7 and the coal bunker housing 1 and dial coal export 8; And link to each other with coal bunker housing 1 level height of end of arc 7 is higher than and dials coal export 8, dials the top that coal export 8 is positioned at screening plant 3.
The utility model is compared with prior art, has following advantage:
Single rod layering coal bunker of this kind of version, it is simple in structure, designs ingenious; It problems such as coal difficulty, canopy coal phenomenon in use often occur dialling to existing two roll-to-roll formula coal bunkers; Change traditional double-roll type coal bunker structure into single rod structure, and be equipped with arc, this structure can block coal moving roller because of having bigger coal cinder in the fire coal or freezing coal cinder; Can effectively these coal cinders be transported on the fire grate smoothly, guarantee the continuous and even of coal supply.And utilize this coal bunker can make the distributed coal beds on the fire grate even, the coal combustion effect is abundant, avoids forming the black coal phenomenon, has improved the thermal efficiency of coal-burning boiler.Therefore we can say that it has possessed multiple advantage, be particularly suitable for and apply in the art that its market prospects are comparatively wide.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below with the specific embodiment of accompanying drawings the utility model.As shown in Figure 1: a kind of single roller layering coal bunker; Comprise coal bunker housing 1; Be provided with charging aperture 2 on the top of coal bunker housing 1, the bottom of coal bunker housing 1 is provided with screening plant 3 and discharging opening, and is coal-fired behind the inner chamber of charging aperture 2 entering coal bunker housings 1; Through behind the screening plant 3, be discharged on the corresponding fire grate from discharging opening; Be provided with coal moving roller 5 in the coal bunker housing 1 below charging aperture 2; Along coal moving roller 5 axially on, be distributed with a plurality of groups of coal bars 6 equably, below coal moving roller 5, be provided with an arc 7; One end of this arc 7 links to each other with coal bunker housing 1; The other end does not link to each other with coal bunker housing 1, form one and dial coal export 8, and the level height of the arc 7 of the end that links to each other with coal bunker housing 1 will be higher than the level height of group coal export 8; Fire coal can be slipped to group coal export 8 from arc 7 under the effect of deadweight like this, dials the top that coal export 8 then is positioned at screening plant 3.
The course of work of single rod layering coal bunker of the utility model embodiment is following: coal-fired through in the charging aperture 2 entering coal bunker housings 1; And drop on the arc 7; Coal-fired effect in deadweight is understood profile along arc 7 down to lower slider; The coal moving roller 5 that is positioned at arc 7 tops then can rotate under the effect of dynamical system, and in the rotating process, group coal bar 6 that is arranged on the coal moving roller 5 can be dialled fire coal diffusing; Let it evenly from dial coal export 8, fall on the screening plant 3, for boiler or fire grate provide coal-fired.Dial simultaneously coal bar 6 can also after will freeze coal cinder or bulk fire coal transfer to from arc 7, make coal-fired supply even, continuous, smooth.
This single rod layering coal bunker coal supply process is simple, stable performance, and reliable operation is convenient to install.
