Abstract

The utility model relates to the design of the front and back smoke boxes of a fuel horizontal boiler. The end face and body of the entire door of the existing smoke box are fixedly connected integrally, a partial elevation door is arranged on the end face, the partial elevation door and the end face are fastened tightly by a plurality of threaded bolts and pressing plates. The utility model overcomes the defects of bulkiness, easy deformation and large machining difficulty in the existing large-area entire elevation door and have the advantages of simple fabrication, light dead weight and small area and large processing equipment can not be used. In addition, a hoisting machine is not needed when the utility model is closed, deformation error can be ignored, etc.

Description

Horizontal boiler smoke box facade door

The utility model relates to the fuel oil horizontal boiler, specifically the design of the forward and backward smoke box door of boiler.

The door of the existing forward and backward smoke box of oil burning boiler is whole facade door, and its facade size is consistent with boiler barrel.Use hinge as connector and support member between facade door and the cylindrical shell, reach sealing with bolted flange separately when closing.This shop front is long-pending excessive, also to often close, for the sealing property between the flange that is provided with on the flange that guarantees to be provided with on the whole facade and the barrel diameter and prevent static state, distortion in dynamically, need to eliminate internal stress through Overheating Treatment earlier, carry out machine cut processing again, complex manufacturing technology.Excessive because of conducting oneself with dignity, when closing, need determine the location in bolt and hole, operating difficulties by hoisting machinery.Also because of in the staggered variation that often is in hot and cold conditions, the deformation error of door is big, and the sealing property between cylindrical shell can descend gradually, causes smoke spillage.

Task of the present utility model is with the method that breaks the whole up into parts, cuts apart the part elevation door is set overcomes above-mentioned defective on whole facade door.

For finishing above-mentioned task, the technical scheme that the utility model proposes is: a kind of horizontal boiler smoke box facade door, has a whole end face, it is as a whole to it is characterized in that this end face and boiler body are fixedly connected into, at this end face one or more part elevation door is set, part elevation door and end face are fastening with a plurality of bolts and pressing plate.

The utility model changes the larger area facade door of available technology adopting into area much smaller part elevation door, and its advantage applies is aspect three: the one, and the processing of door is simple, does not need large-sized processing equipment, has reduced production cost; The 2nd, weight reduction is closed Shi Buxu and is used hoisting machinery, provides users with the convenient; The 3rd, the facade area is little, and the deformation error that produces in the staggered variation of hot and cold conditions can be ignored, and has guaranteed sealing property.

Provide embodiment of the present utility model and accompanying drawing below.

Fig. 1 is front and back smoke box facade door schematic perspective views.

Fig. 2 is the side view of front smoke box part elevation door.

Fig. 3 is the side view of back smoke box part elevation door.

Fig. 4 is the schematic diagram that pressing plate and part elevation door are in restraint location.

Embodiment shown in the drawings, its front smoke box facade door has a whole end face 1, this end face 1 and boiler body 2 are fixedly connected into as a whole, at this end face 1 two part elevation doors 3 are set, and also can three part elevation doors 3 be set according to burner hearth water pipe array (figure does not show).Back smoke box facade door is identical with front smoke box facade door, also have a whole end face 1 ', this end face 1 ' also fixedly connected with boiler body 2 is integral, this end face 1 ' on be provided with a part elevation door 3 ', also can according to the water pipe array be provided with two part elevation doors 3 '.The number of above front and back smoke box part elevation door is exceeded to satisfy the needs that use and keep in repair, and the shape of its facade can adopt

Shape or

Shape is equipped with attached circle 5 in the inboard of each part elevation door, lay heat-insulation layer in this attached circle 5.Each part elevation door 3 or 3 ' with place end face 1 and 1 ' many bolts 4 of employing and the pressing plate 6 fastening sealing effectiveness that reach.This pressing plate is

Shape, its minor face end 7 as the strong point be pressed on end face 1 and 1 ' on, its end 8, long limit as pressure point be pressed on each part elevation door 3 and 3 ' the edge on, the middle part on long limit is provided with through hole 9, be connected in end face 1 and 1 ' bolt 4 through this through hole 9.Comparatively frequent because of the part elevation door keying of front smoke box, can between door and end face, add hinge.

Claims
