Description
Technical field
The utility model relates to dredge block apparatus technical field, and in particular to a kind of coal-burning boiler automatic sparse block apparatus.
Background technique
Coking, castable fall off the phenomenon that blocking slag-drip opening coal-fired boiler in thermal power plant operational process frequent occurrence, and one
Denier blocks, and boiler bottom slag can not be discharged in time, and boiler bed material height will increase, and influences boiler normal operation, such as too late
Shi Shutong will cause very big economic loss to power plant.
To guarantee that boiler operates normally, power plant is just carried out dredging and be blocked up, and is commonly provided with special personnel and is manually dredged
It is stifled, it is not only time-consuming and laborious, and because bottom ash temperature is up to 1000 DEG C, cinder notch periphery is disclosed since heat radiates, environment temperature is very high,
Staff usually risks high temperature and artificial dredge of dangerous progress of scald is blocked up, and smoothly dredges quickly, ill words will
Long-time operation, and boiler blocking is frequently, needs often progress manually to dredge stifled, heavy workload, working strength is high, operating condition evil
It is bad and dangerous, it is also very poor to dredge stifled effect.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and providing one kind can substitute now
It is artificial dredge stifled, the thin block apparatus being automatically brought into operation and coal-burning boiler automatic sparse block apparatus may be implemented.
It is for technical solution used by realization the purpose of this utility model:
A kind of coal-burning boiler automatic sparse block apparatus, including be mounted on connection slag-drip opening slag channel on, including executing agency,
Drill rod, broken sword, shutoff door, sealing device；One end of the side connector drum of the shutoff door, the cylinder is interior to install institute
Drill rod is stated, there is broken sword on the front end of the drill rod, what the drill rod rear end connected the executing agency can be repeatedly
The push rod of linear motion has sealing device in the cylinder.
The end cap with holes of T-shaped structure is bolted in the other end of the cylinder.
The broken sword includes the sword body of multiple right triangular shapes, is evenly arranged in the outer of the front end of the drill rod
On wall.
The coal-burning boiler automatic sparse block apparatus of the utility model is a kind of thin block apparatus that can be automatically brought into operation, substitution
It is present it is artificial dredge it is stifled, dredge stifled effect than it is artificial dredge it is stifled significantly improves, dredge block up it is more efficient, it is time saving and energy saving, securely and reliably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of coal-burning boiler automatic sparse block apparatus.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
It is shown in Figure 1, a kind of coal-burning boiler automatic sparse block apparatus, including being mounted on the slag channel of connection slag-drip opening,
Including executing agency 1, drill rod 2, broken sword 3, electric shutting-door 4, sealing device 5；The side connector drum 6 of the shutoff door
One end, the installation drill rod in the cylinder has broken sword on the front end of the drill rod, is crushed sword in cylinder,
The drill rod rear end connects the push rod (not shown) that can be moved along a straight line repeatedly of the executing agency, has in the cylinder 6
The sealing device 5 is located at the nearly outboard end of the cylinder, the high temperature ash that drill rod 2 and broken sword 3 are taken back when stopping backhaul
Slag avoids causing to damage to the piston rod or push rod of executing agency 1.
Wherein, the end cap with holes 7 of T-shaped structure is bolted in the other end (outboard end) of the cylinder.
Wherein, the broken sword includes the sword body of multiple right triangular shapes, is evenly arranged in the front end of the drill rod
On the outer wall in portion.
Further, the outer cover of the drill rod is described in the connection cylinder and the sleeve 8 of executing agency
One end of sleeve and one end of executing agency 1 are fixed, and the other end is extend into the cylinder, institute through the hole on the end cap 7
The other end for stating sleeve is connect with the intracorporal orifice plate 9 of the cylinder is welded on, and the internal diameter of orifice plate 9 and the internal diameter of sleeve are consistent,
In, the outer wall of the orifice plate and the inner wall of cylinder are sealedly connected and fixed, and the drill rod stretches out from the orifice plate 9 and stretches to shutdown
Door, as shown in Figure 1, between orifice plate and end cap and end cap and sleeve, cylinder inner wall or outer wall between be filled with sealing device
5, the sealing device 5 is using similar materials such as airtight and watertight paddings.The end cap with holes 7 of the T-shaped structure is extend into cylinder, and
It is placed between cylinder and sleeve, as shown in Figure 1.
The automatic sparse block apparatus of the utility model is mounted on the slag channel of connection slag-drip opening, without the stifled operation of automatic sparse
When, electric shutting-door 4 is in close state, isolation slag channel and automatic sparse block apparatus, avoids high-temperature ash to the stifled dress of automatic sparse
The damage set, 4 other side of electric shutting-door can weld disclosing on the outside of cinder notch on the slag channel for being mounted on connection slag-drip opening, with slag
Cinder notch of disclosing on channel is fixedly connected.
When slag-drip opening blocks, electric shutting-door 4 is first turned on, opens and dredges stifled channel, executing agency 1 opens, pushes away
Dynamic 2 faster reciprocal motion of drill rod, coke button, the castable etc. for being mounted on 3 pairs of broken sword blocking slag-drip openings of 2 end of drill rod carry out brokenly
It is broken.
The sealing device 5 will stop the high-temperature ash that drill rod 2 and broken sword 3 are taken back when backhaul, avoid to execution machine
The piston rod or push rod of structure 1 cause to damage.
The broken sword 3 is made by the high-strength stainless steel of Wear-resistant, high-temperature resistant, tapered, can be ascending gradually to stifled
It is broken that plug thing carries out strength.
After dredging slag-drip opening, executing agency 1 withdraws drill rod 2 and broken sword 3, and electric shutting-door 4 is closed, and protection is automatic
Dredge block apparatus.
It should be noted that the executing agency can be with pneumatic actuator such as cylinder in the utility model, or
Other automatic executing agencies such as electric operator, electrohydraulic actuator.
In the utility model, the electric shutting-door can not be set.If set, the electric shutting-door can
Think the shutoff door of other automation control mechanism drivings such as pneumatic, electro-hydraulic driving.
In addition, it is necessary to explanation, the sealing device, broken sword can not also be set.
Automatic control can be used in the utility model, and automatic operation carries out high-strength in the high temperature environment without staff
The manual operation of degree, high-risk, and thin stifled effect is significantly improved than manually dredging to block up, it is more efficient, it is time saving and energy saving, securely and reliably.
The coal-burning boiler automatic sparse block apparatus of the utility model is a kind of thin block apparatus that can be automatically brought into operation, and substitutes present people
Work dredge it is stifled, dredge stifled effect than it is artificial dredge it is stifled significantly improves, dredge block up it is more efficient, it is time saving and energy saving, securely and reliably.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
