The utility model has the advantages of simple structure, high sensitivity and the like, reduces the probability of blockage caused by excessive discharge, improves the backfire resisting capability, and is suitable to be used for improving the fire resisting door of the feeding system of the traditional biological substance power generation facility.
Description
Technical field
The utility model relates to the biomass energy development field, and refering in particular to is a kind of feeding system fireproof door, is applied to biomass power generation equipment.
Background technology
Though bioelectrogenesis is started late in China, but at trend pickup in recent years, when biomass power generation speeds up, biomass electric power plant ubiquity feeding system feed stops up and the tempering of biomass fuel after the burner hearth burning is burned to material mouthful initiation feed bin burning, injury life security problems, for head it off, most of biomass electric power plants come quick anti-backfire by designing electronic quick-break door, electronic quick-break door according to the flame monitoring system monitoring behind flame, starter motor cuts out the anti-backfire door and cuts off flame, flame is opened after disappearing automatically again, but in actual applications, electronic quick-break door running is slow in one's movements, misoperation sometimes appears, cause electronic quick-break door not open, make biomass fuel be blocked in electronic quick-break door place, have a strong impact on the combustion stability of boiler, cause the major accident of boiler extinguishment; Electronic quick-break door does not close when perhaps tempering being arranged, and causes tempering to be burned to feed bin, and initiation fire.
The utility model content
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple in structure, highly sensitive, reduce blanking and too much cause the probability of stopping up, the feeding system fireproof door that improves the anti-backfire ability.
The purpose of this utility model is achieved by following technical proposals:
A kind of feeding system fireproof door, comprise anti-backfire door, rotating shaft, retreat stop block, described anti-backfire door is installed in the blanking pipeline by described rotating shaft and is complementary with the size shape of described blanking pipeline, the described retreat stop block that stops described anti-backfire door counter-rotating is installed in the blanking pipeline, at least one end of described rotating shaft is arranged on described blanking pipeline outside, be arranged in the outside described rotating shaft and be connected with connecting rod, the end of described connecting rod is hung with counterweight by suspended axle.
In the utility model, described counterweight is provided with regulating tank, is fitted with the sensitivity adjusting rod in the described regulating tank.
In the utility model, the center of gravity of described counterweight is positioned at the other end of suspended axle on the counterweight.
In the utility model, 3 at the hitch point center of the center of gravity of described anti-backfire door, rotating shaft center, counterweight is positioned on the straight line.
In the utility model, described sensitivity adjusting rod is divided into degree of closing adjusting rod and aperture adjusting rod.
Owing to adopt above-mentioned scheme, utilize principle of moment balance can reduce the thrust that promotes the anti-backfire door on the one hand, only need less power just can promote the anti-backfire door, no matter make biomass fuel or tempering can both promote the anti-backfire door very easily, make biomass fuel like this when blanking, the aperture of anti-backfire door is bigger, making fuel fall into the preceding resistance of burner hearth reduces, reduced the probability of stopping up, simultaneously when tempering produces, also easily the anti-backfire door in time is pushed to the position of sealing, has also improved anti-backfire ability; Can change anti-backfire door and the unbalanced angle of counterweight torque by the sensitivity adjusting rod on the other hand, reach the purpose of regulating anti-backfire door initial angle and equilibrium region, guarantee the smooth and easy and anti-backfire action message of blanking, the sensitivity adjusting rod is divided into degree of closing adjusting rod and aperture adjusting rod, degree of closing adjusting rod can be adjusted the scope of minimum aperture, guarantees the smooth and easy of blanking; The aperture adjusting rod can be regulated the scope that an anti-backfire Men Youyi maximum is opened, and when crossing the aperture scope, fuel thrust reduces or disappears, and the anti-backfire goalkeeper returns static region automatically, and the reliability of action can realize by it.
In sum, the utlity model has advantages such as probability simple in structure, highly sensitive, as to reduce the too much obstruction of blanking, raising anti-backfire ability, be applicable to improvement existing biomass power generation equipment feeding system fireproof door.

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of feeding system fireproof door in detail.
As Fig. 1,2,3, shown in 4, a kind of feeding system fireproof door, comprise anti-backfire door 7, rotating shaft 5, retreat stop block 6, described anti-backfire door 7 is installed in the blanking pipeline 8 by described rotating shaft 5 and is complementary with the size shape of described blanking pipeline 8, the described retreat stop block 6 that stops described anti-backfire door 7 counter-rotatings is installed in the blanking pipeline 8, described rotating shaft 5 at least one ends are arranged on described blanking pipeline 8 outsides, be arranged in the outside described rotating shaft 5 and be connected with connecting rod 4, the end of described connecting rod 4 is hung with counterweight 2 by suspended axle 1, described counterweight 2 is provided with regulating tank 9, is fitted with the sensitivity adjusting rod in the described regulating tank 9.
In the said structure, 3 at the hitch point center of the center of gravity of described anti-backfire door 7, rotating shaft 5 centers, counterweight 2 is positioned on the straight line, anti-backfire door 7 satisfies torque balance with counterweight 25 rotations around the shaft, the focus point of counterweight 2 is positioned at the other end of suspended axle 1 on the counterweight 2, counterweight 2 makes hitch point center and 2 places of counterweight 2 centers of gravity rectilinear direction keep straight down relying on suspended axle 1 to swing flexibly on connecting rod 4; The sensitivity adjusting rod that is provided with on the counterweight 2 can regulating tank 9 interior adjustings thereon be fixed, an other end of counterweight 2 sensitivity adjusting rod in swing is stuck on the connecting rod 4, the swing of limiting balance hammer 2, thereby change the size of moment, change the unbalanced angle of torque, realize the static state setting of aperture.
In application process, can realize the size of static aperture scope by the position of sensitivity adjusting rod in regulating tank 9 is set, just regulate the angular range of torque balance, the sensitivity adjusting rod is divided into degree of closing adjusting rod 10 and aperture adjusting rod 3, as shown in Figure 5, the size of both adjustable range decision tatic range A, cross tatic range A, arrive in the non-tatic range B, torque just loses rotary balance, counterweight 2 will drive anti-backfire door 7 trend of returning tatic range A, under operate as normal or off position, anti-backfire door 7 is still in static region A, the active force that needs when anti-backfire door 7 moves in static region A is less, the rapid action and the aperture that help anti-backfire door 7 like this, can solve the influence of the big and big generation putty of aperture torque drag of anti-backfire door 7 resistances, and in non-tatic range B, counterweight 2 will be to 7 one power of returning tatic range A of anti-backfire door, make when anti-backfire door 7 apertures are excessive or too small like this, the easier position of getting back to static region A, prevent that biomass fuel from promoting the aperture of anti-backfire door 7 when excessive, anti-backfire door 7 withstands on the top of blanking pipeline 8 can't return, and tempering also can't promote anti-backfire door 7 returns, thereby enter feed bin, initiation fire.
