Abstract
The utility model relates to a main chimney baffle door and is characterized in that the main chimney baffle door has a butterfly-shaped opposite-open-type door body, door shafts are arranged on the left and the right parts of the door body, a ratchet mechanism is mounted on either of the door shafts, the ratchet mechanism is connected with a driving mechanism, the two parts of the door body are connected with each other through a crankshaft link mechanism, the ratchet of the ratchet mechanism is fixed on a driving shaft, the pawl of the ratchet mechanism is fixedly connected with the driving mechanism, and two spring components are arranged on the driving mechanism. The main chimney baffle door has the benefits that the structure is simple and reliable; and compared with the prior shutter-type structure, the number of the sealed edges is remarkably reduced and the sealing effect is better.
Description
Technical field
The utility model relates to a kind of boiler, relates in particular to a kind of flue damper door of waste heat boiler.
Background technology
Main flue damper door is applied in the various combustion machine waste heat boilers, purpose is at the waste heat boiler furnace shutdown period, by closing main flue damper door, can effectively block funnel draft, thereby significantly reduce the heat radiation of waste heat boiler, life-span that can not only prolonged boiler more helps shortening waste heat boiler and resets required time, and is obvious to large and medium-sized combustion machine waste heat boiler daily start-stop effect.The main flue damper door of prior art generally adopts the venetian blind type structure, and its seal perimeter is long, and sealing effectiveness is not ideal enough.
Summary of the invention
The utility model main purpose is: solve the existing in prior technology deficiency, thereby develop a kind of good sealing effect, reliable in structure, the main flue damper door of stable working.
Another purpose of the utility model provides a kind of main flue damper door with safeguard protection effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of main flue damper door, it is characterized in that: have butterfly type opposite opened door body, the left and right door body is provided with door-hinge, on one of them door-hinge ratchet mechanism is installed, described ratchet mechanism links to each other with driving mechanism, adopts toggle to interconnect between described two.
The technical solution of the utility model can also be further perfect;
As preferably, the ratchet of described ratchet mechanism is fixed on the driving shaft, and the ratchet and the driving mechanism of described ratchet mechanism are affixed.
As preferably, two spring assemblies are installed on the described driving mechanism.
As preferably, described driving mechanism is an actuator.
Therefore, the beneficial effects of the utility model are simple in structure, reliable, compare with the venetian blind type structure, and seal perimeter obviously reduces, and sealing effectiveness is better.
The utility model can also make baffle door under closing state, and flue gas is above the situation of release pressure in the waste heat boiler if take place, and actuator is failure to actuate; and baffle door is opened under the effect of flue gas pressures automatically; release pressure, pressure is closed after descending automatically, plays the safeguard protection effect.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is drawings in side sectional elevation of Fig. 1;
Accompanying drawing 3 is ratchet mechanism enlarged drawings of Fig. 1.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Main flue damper door as shown in Figure 1 to Figure 3,1,2 shaft couplings, 3 actuators, 4 centre joint plates, 5 Sensor boxs, 6 position indicator pointers, 7 spring assemblies, 8 ratchets, 9 ratchets.
About two fan doors, 1 usefulness toggles interconnect, guarantees two run-in synchronisms. and actuator of need only.Main flue damper door drive mechanism adopts German original-pack AUMA actuator 3, and opening speed is 50～60S/ time, uses stable working, reliable.
In the drive chain design, adopt the ratchet mechanism (see figure 3), wherein ratchet 8 is fixed with actuator 3, and ratchet 9 is fixed on the driving shaft of the right door, and two spring assemblies 7 are housed on driving shaft.
During work, the action of opening the door is to drive ratchet 8 by actuator 3, heads on ratchet 9 and does rotation counterclockwise, and door is also opened in the counterclockwise direction slowly.The action of closing the door is the counter-rotating of actuator motor, and it drives ratchet 8 and does the clockwise direction rotation, and ratchet retreats along hook tooth, do the clockwise direction rotation for ratchet 9 and vacate locational space, under the gravity effect, door (being with ratchet) clockwise rotates, and door is just closed slowly.
The normal unlatching of left and right door of the present utility model is to rely on actuator driven, and the gravity distance of door self countershaft is the real driving force distance of closing the door.When door is opened near 90 °, the gravity of door will approach pivot center apart from position, driving force becomes very little apart from meeting, so that can not overcome the frictional resistance distance between bearing, at this moment door just can not be closed, and relies on two spring assemblies 7 that are arranged on the driving mechanism, when making door be opened near 90 °, make spring be subjected to sufficiently compressing, form a moment, required moment when supplying with door and closing.
Present embodiment is used on 9F master's flue damper door, and driving mechanism adopts German AUMA actuator, and the baffle door bearings at both ends adopts the spherical rolling bearing of usheing to seat, and can satisfy baffle door axial length, characteristics that amount of deflection is bigger.
The Position Control of main flue damper door (100% open with 0% close spacing) all adopt three independent signals outputs, thereby guarantee its position reliability, and the output of 4～20ma/24VDC signal is arranged, can carry out Long-distance Control.After baffle door is closed, can automatically rainwater be discharged outside the chimney.
The utility model can make baffle door under closing state, and flue gas is above the situation of release pressure in the waste heat boiler if take place, and actuator is failure to actuate, and door is opened under the effect of flue gas pressures automatically, and release pressure plays the safeguard protection effect.
