Abstract
The utility model belongs to the technical field of a boiler check device, and particularly relates to a pressure combustion compression check device of a boiler. The pressure combustion compression check device of the boiler mainly solves the problems that the pressure combustion compression check device of the boiler is poor in tightness at present, a face plate is not easy to open and close, a hook is easy to crack and the face plate easily deforms. The technical scheme disclosed by the utility model is that the pressure combustion compression check device of the boiler comprises the face plate, a retainer, a door frame, the hook, a lock arm and a handwheel device; the compression check device adopts a labyrinth sealing mortise structure; the face plate is connected with the door frame; the retainer is arranged between the face plate and the door frame; the right end of the lock arm is connected with the left end of the door frame; the left end of the lock arm is connected with the hook; a buckle section matched with the hook is arranged at the left end of the door frame; the hook is buckled together with the buckle section; the handwheel device is arranged at the middle part of the lock arm, and a screw of the handwheel device passes through the lock arm to resist against the face plate. The pressure combustion compression check device of the boiler has the advantages of being simple in structure, easy to open and close, and good in tightness, and the hook does not easily crack.
Description
Technical field
The utility model belongs to boiler inspection device technique field, is specifically related to a kind of boiler positive pressuring combustion resistance to compression testing fixture.
Background technology
At present, energy saving and environment friendly burning in circulating fluid bed boiler just reaches its maturity, and the boiler material circulating system is slight positive pressure state, the manhole inspection door that then arranges at the position of its required inspection just must adopt the testing fixture of compression-resistant type, guarantee the sealing of boiler, thereby boiler can steady in a long-term be moved.
Pressure combustion resistance to compression testing fixture is the critical component of CFBB, is the critical passage that enters the maintenance of burner hearth inspection and maintenance behind the boiler shutdown.For a long time, employed resistance to compression testing fixture is because its critical piece structural design is unreasonable, correlated parts cooperates relatively poor, poor sealing, door closure device is difficult for switch, component thickness and intensity can not satisfy actual motion requirement etc., when causing boiler stove internal combustion malleation be excessive in running, the resistance to compression testing fixture is washed open, fracture appears in the hook place, the side towards the fire of testing fixture door closure when serious, door closure is partly crossed to crumple, form the gap between door closure and the doorframe, smoke spillage occurs, cause the boiler operatiopn environment poor, the boiler forced outage causes a series of loss when serious.
Summary of the invention
The utility model exists poor sealing, door closure to be difficult for switch, the problems such as hook easy fracture, door closure distortion mainly for present boiler positive pressuring combustion resistance to compression testing fixture, provide a kind of simple in structure, be easy to switch, good airproof performance, link up with the not boiler positive pressuring combustion resistance to compression testing fixture of easy fracture.
The technical scheme that the utility model is taked for achieving the above object is:
A kind of boiler positive pressuring combustion resistance to compression testing fixture, comprise door closure, guard ring, doorframe, hook, locking arm, wherein: also comprise handwheel devices, described resistance to compression testing fixture adopts the labyrinth sealing tenon groove structure, and described door closure is connected with doorframe, and guard ring is located between door closure and the doorframe, the right-hand member of locking arm is connected with the right-hand member of doorframe, the left end of locking arm is connected with hook, is provided with and links up with the buckling parts that is complementary at the left end of doorframe, and hook fastens with buckling parts; Handwheel devices is located at the middle part of locking arm, and the screw rod of handwheel devices passes locking arm and press on the door closure top.
Described door closure is divided into inside and outside two-layer, and the internal layer side towards the fire adopts exotic material to make.
Described buckling parts is the structure that slopes inwardly, and its gradient is less than 1:10.
The utility model adopts technique scheme, and whole device adopts mazy hermetically-sealed construction, guarantees that the overall sealing performance of resistance to compression device is better, and is easy to switch; Door closure is two-layer inside and outside being divided into simultaneously, and it is too high that the internal layer exotic material is difficult for outer field metal temperature, guarantees the design performance of whole device; Hook adopts the single-casting structure, and door closure and locking arm are firmly linked closely; Handwheel devices can conveniently be opened the door closure of high temperature or playback, and has overcome fit structure complicated between original and the door closure; Locking arm makes handwheel that door closure is compressed, and be connected with door closure, dedicated hook and and doorframe link closely mutually, fixed the relative position of door closure; Door closure and locking arm buckling parts adopt the design of the certain angle that slopes inwardly, and be when being in pressured state, more tight; Handwheel devices adopts the handwheel devices screw rod directly and press on top, door closure surface, has overcome fit structure complicated between original and the door closure, with the enhanced leaktightness effect.Therefore compared with prior art, the utility model manufacturing process is simple, installation and repairing and replacing are convenient, so that boiler furnace resistance to compression testing fixture has more security reliability, even when furnace pressure increases, also can guarantee the normal operation of boiler, reduce operating cost, prolong the service life of resistance to compression device, reduce potential safety hazard.
