Abstract
The utility model belongs to a furnace door body used for monitoring the burning state or the reaction state in a furnace and an industrial furnace, comprising a furnace door box, a movable furnace door plate in the box, an air inlet ring for sealing the air and an air sealing inlet. A furnace door hole is arranged on the front part of the box body, and the end surface where the inside of the furnace door hole is matched with the furnace door plate is an inclined surface. The gravitational force automatic-lock principle is utilized to ensure the compression seal state when the furnace door plate and the furnace door hole close automatically. Thus, a control mechanism of the furnace door is simple and reliable and has favorable sealability; in addition, a probe can be extended in a furnace chamber; the utility model has the characteristics of flexible and convenient use, safety, etc. and overcomes the defects that the control mechanism of the furnace door in the background art is complex and has poor reliability, unfavorable safety, poor sealability, etc.
Description
The utility model is a kind of fire door body that boiler and Industrial Stoves stove internal combustion situation or reaction condition are monitored of being used for; Particularly a kind of fire door body that can stretch into and withdraw from and open and close automatically, seal with high temperature monitor probe.
Most station boiler, Industrial Boiler and Industrial Stoves etc. all adopt the high temperature monitor to observe and to monitor stove internal combustion situation or response situation.Burner hearth and extraneous sealing can be isolated again after the peep hole of body of heater stretches into burner hearth work and withdraws from body of heater for the ease of the monitor probe, therefore be equipped with a movable fire door in the outside of peep hole.At present, the home and abroad all generally adopt bar linkage structure or mode of traction control door opened, close.The former needs at first outwards to open fire door by actuator drivening rod mechanism before probe stretches into body of heater; After withdrawing from, probe also needs it to be closed by actuator; This type of fire door, the one, structure and controlling organization complexity; The 2nd, linkage is in the adverse circumstances of high temperature, high bisque for a long time works, and easily rotates dumb between the connecting rod and fault such as kills and influence the stability and the reliability of work; In addition,, then also higher in the time of reaching fire door and close to the requirement of the machining accuracy of fire door and controlling organization to the requirement of sealing.And the latter adopts the mode of vertical distraction to control the switch of fire door, though structure is simple than the former relatively, but still haulage gear need be set, and because the mating surface of movable fire door and firedoor hole is all perpendicular to the horizontal plane setting, so be no pressure contact between two mating surfaces, its stability and sealing extreme difference particularly are under the situation of malleation at burner hearth, and furnace flame easily ejection burns out monitoring equipment.Both all are not provided with air seal when probe work in addition, influence monitoring and burn equipment because of the high-temperature flue gas guest performer when burner hearth is malleation.Therefore, above-mentioned technology all exists fire door controlling organization complexity, disadvantages such as reliability and sealing difference.
The purpose of this utility model is that a kind of travelling oven gate control of design mechanism is simple, and can close automatically, good airproof performance in the time of in off position, safe and reliable and probe stretch into burner hearth when work can adjust the closing automatically of its aperture, sealed fire door with the action of probe.
Solution of the present utility model be with fire door be designed to one independently parts and be fixed on the body of heater monitoring holes by the flange type connector use, this fire door comprises the fire door case, firedoor hole, travelling oven door-plate on the firedoor hole is located in the nationality body and is inwardly opened, its sealing means is according to the gravity self-locking principle, when probe withdraws from burner hearth, utilize the deadweight of travelling oven door-plate, make itself and firedoor hole working face be pressure and contact to improve its sealing.Its concrete grammar is that the working face that the inboard with firedoor hole cooperates with movable doorboard is designed to the inclined-plane, when movable doorboard is contacted with this inclined-plane, utilize the travelling oven door-plate from gravity in the horizontal direction component and form pressure contact, thereby improve its sealing effectively; Simultaneously establish a roller in the lower end of travelling oven door-plate so that probe push open door-plate enter in the burner hearth process with door-plate between be rolling friction and contact.Therefore, the utility model comprises firedoor hole and travelling oven door-plate provided thereon; Key is that it also comprises a fire door case, and firedoor hole is located at the front portion of this casing, and the travelling oven door-plate is located in the casing at firedoor hole rear portion, and the inner side end that firedoor hole cooperates with the travelling oven door-plate is the inclined-plane; Lower end at the travelling oven door-plate also is provided with a roller; The travelling oven door-plate passes through turning cylinder or axle hinge and bearing and is connected with the fire door casing, and whole fire door body then is anchored on the body of heater peep hole by connector and uses.The gradient of the inner side end that above-mentioned firedoor hole cooperates with the travelling oven door-plate is to be advisable in 12 °~25 ° scopes with the angle of shaft section.When stretching into burner hearth, because of door opened contingent high-temperature flue gas guest performer influences monitoring or burn equipment in order to prevent to pop one's head in.One sealing air air inlet ring and sealing air inlet also can be set at fire door casing rear portion.
The utility model is owing to be designed to parts independently with whole fire door body, and utilize the gravity self-locking principle that the contact-making surface of travelling oven door-plate and firedoor hole is designed to the inclined-plane, by stove door plant self gravitation component in the horizontal direction, make stove door plant after probe withdraws from, close automatically and with firedoor hole between be pressure and contact, thereby improved sealing greatly; Stove door plant is connected with the fire door casing by rotating shaft or axle hinge and bearing, and it is simple in structure, reliable, difficult fault such as kill in the work; In the stove door plant lower end one roller is set, push open to make in the process that stove door plant enters burner hearth when probe and be rolling friction between probe and the movable fire door and contact, both be convenient to probe and moved freely, easy damaged probing shell not, and the aperture of fire door again also can change flexibly with the probe duty.In fire door case rear annular the sealing air air admission hole is set, the high-temperature flue gas guest performer influences monitoring or burn equipment in the time of can avoiding popping one's head in work again.Therefore, it is simple, reliable to the utlity model has the fire door controlling organization, and good airproof performance, probe stretch into burner hearth and characteristics such as flexible and convenient to use, safe.Thereby overcome fire door controlling organization complexity in the background technology, reliability.Disadvantages such as security and sealing difference.
