Description
Technical field
The utility model is related to power plant's coal scuttle fields more particularly to a kind of for removing the reciprocating broken of coal scuttle arching phenomenon
Arch machine.
Background technology
In power plant combustion system, coal scuttle is important one of equipment, as shown in Figure 1,1 shape of coal scuttle be generally hyperbola or
Cone or prismoid shaped, it is because silo exports 8 sizes and limited by the batcher import size of feeder 2 to make tapered line style
System.
There are one serious problems, i.e. raw coal " arch camber " for the coal scuttle of tapered line style.Raw coal " arch camber " in coal scuttle, also referred to as
" bridging " phenomenon is common problem in coal scuttle operation, as shown in Fig. 2, after piling with raw coal in coal scuttle 1, raw coal because itself
Stickiness or since the equal transient causes that make moist cause raw coal to be bonded in barrel 9, the raw coal of bonding part above the horizon all bonds
Together, after the raw coal export not glued on coal scuttle center line when discharging, cohesive body central part is because losing support, cohesive force
Less than its own gravity, it can also fall and coal scuttle, left part is exactly so-called " arch camber " or " bridging ".It solves " arch camber "
The method of problem usually increases air bubble on silo, also useful pneumatic hammer, and both methods has certain effect,
But disadvantage is it is also obvious that one is that investment increases；Second is that when raw coal viscosity is bigger, air bubble will appear the feelings for the more beating the more closely knit
Condition makes the adhesive force of itself and silo greatly reinforce, this has just played reaction, and the side effect of pneumatic hammer is substantially similar, additionally
Greatly destroy the structural strength of silo.
Therefore, it for disadvantages described above, needs effectively to innovate the prior art.
Utility model content
To overcome above-mentioned the deficiencies in the prior art, the utility model, which provides, can remove the one of the raw coal clung in coal scuttle
Reciprocating broken arch machine of the kind for removing coal scuttle arching phenomenon, including coal scuttle, feeder, belt layer floor, it is characterised in that：Also
Including broken arch machine；
The feeder is arranged at the coal scuttle lower port, and the coal scuttle lower port is seamless contacts, the belt
Floor plate is horizontally installed on above the feeder, and the broken arch machine is fixed on the belt layer floor；Wherein,
The broken arch machine includes motor, reciprocating engine, broken arch bar and broken arch strut；
The motor reel connects the reciprocating engine, and broken arch bar one end is vertically arranged in the reciprocating engine, the other end
It is inserted vertically into the coal scuttle, the broken arch strut is uniformly welded on the surrounding of the broken arch bar, the control system obliquely
Signal end be electrically connected the motor and the feeder.
Preferably, the control system is PLC system or DCS system.
Preferably, the motor is adjustable frequency motor.
Preferably, the broken arch strut is equipped with multiple.
Compared with prior art, the utility model has the characteristics that following have：
By the transformation to coal bucket structure, " arch camber " phenomenon of raw material in coal scuttle, and the utility model are efficiently solved
It is simple in structure, it is easy to operate, safeguard that transformation is convenient, high degree of automation.
Description of the drawings
Fig. 1 is coal bucket structure schematic diagram；
Fig. 2 is coal scuttle internal structure schematic diagram；
Fig. 3 is the utility model structure diagram；
Fig. 4 is broken arch bar and broken arch strut combination vertical view.
In figure：
1, coal scuttle, 2, feeder, 3, belt layer floor, 4, motor, 5, reciprocating engine, 6, broken arch bar, 7, broken arch strut,
8, silo exports, and 9, barrel.
Specific implementation mode
To achieve the above object, the utility model provides following technical scheme：
A kind of reciprocating broken arch machine for removing coal scuttle arching phenomenon, including coal scuttle 1, feeder 2, belt layer floor 3,
It is characterized in that：It further include broken arch machine；
The feeder 2 is arranged at 1 lower port of the coal scuttle, and 1 lower port of the coal scuttle is seamless contacts, the skin
Belt floor 3 is horizontally installed on 2 top of the feeder, and the broken arch machine is fixed on the belt layer floor 3；Its
In,
The broken arch machine includes motor 4, reciprocating engine 5, broken arch bar 6 and broken arch strut 7；
4 axis of the motor connects the reciprocating engine 5, and described 6 one end of broken arch bar is vertically arranged in the reciprocating engine 5, separately
One end is inserted vertically into the coal scuttle 1, and the broken arch strut 7 is uniformly welded on the surrounding of the broken arch bar 6, the control obliquely
The signal end of system processed is electrically connected the motor 4 and the feeder 2.
Usually, when needing to be purged the raw coal in the coal scuttle 1, when the feeder 2 sends out disconnected coal signal
When, the motor 4 drives the reciprocating engine 5, reciprocating engine 5 to start immediately, and reciprocating engine 5 drives about the 6 broken arch bar to fluctuate,
The broken arch strut 7 is also constantly fluctuating, and broken arch strut 7 constantly gives scrambling power to the arch of arch camber in coal scuttle middle part, until
Broken arch process terminates.When the feeder 2 sends out normal work signal, the broken arch organ stops.
Further, the control system is PLC system or DCS system, can thus facilitate the setting broken arch machine
Operation express delivery, amplitude and frequency.
Further, the motor 4 is adjustable frequency motor, thus more can neatly control the speed of the reciprocating engine 5
Degree.
Further, the broken arch strut is equipped with multiple.
The above-mentioned description to embodiment is for the ease of those skilled in the art it will be appreciated that and using this
Case technology, person skilled in the art obviously can make various modifications to these examples easily, and described herein one
As principle be applied in other embodiments without having to go through creative labor.Therefore, this case is not limited to above example, ability
For the technical staff in domain according to the announcement of this case, the improvement made for this case and modification all should be in the protection domains of this case.
