Abstract
The utility model relates to a uniform-pressure wind regulating device for a boiler, which belongs to the boiler ventilation technology, and particularly relates to the ventilation technology of the ordinary chain grate boilers. The inner and the outer side walls of a boiler are respectively provided with a rectangular wind inlet and a rectangular baffle opening; wind channels of the boiler are symmetrical left and right; double pull rods on a wind regulating plate of the rectangular wind inlet extend out of the boiler through a pull rod hole on a rectangular baffle; a pull rod handle is welded for being convenient for the wind regulating operation; a uniform-pressure wind regulating plate is arranged in a wind chamber for eliminating the residual dynamic pressure of air flows to cause the wind chamber to keep static pressure and balance. The utility model has the advantages of simplicity, convenience, and flexibility, and can be popularized and used in the improvement and the manufacture of the boilers.
Description
The even louver of pressing of boiler of the present utility model relates to the boiler draft technology.
The balance pipe cloth wind technology of existing boiler and the wind chamber sealing technology etc. of establishing dust remover, all emphasize the overall tightness of boiler, but when the dust stratification that is in operation is too much, resistance is excessive, dust remover can not be brought into play usefulness, and the long-pending full whole air compartment of ashes stops up the averaging wind pipe air-distribution device then, cause incendiary obstacle, the shutdown maintenance of having to.
The purpose of this utility model is to propose the even louver of pressing of a kind of boiler.This device is combined by the air regulating board of air inlet, rectangle plate washer mechanism and even orifice plate three parts of pressing, this apparatus structure rationally, simple, can realize that even the pressure transfer wind, the convenient observation and the multiple function of maintenance.
Accompanying drawing 1 is a mounting structure sketch of the present utility model, and related element and numbering division are as follows:
(1) the even orifice plate of pressing of air compartment (2) air compartment side plate (3) solebar angle (4)
(5) inside wall (6) air inlet (7) air regulating board (8) pull bar
(9) rob support (10) rectangle plate washer (11) tie rod hole (12) handle
(13) external wall (14) dust remover control stick describes structural principle in detail below in conjunction with accompanying drawing.
On the inside and outside side wall relevant position of boiler air compartment one end, respectively have rectangular aperture, the rectangular aperture that inside wall (5) is left in suitable location according to design, weld out rectangle air inlet (6) with steel plate, the physical dimension of the air regulating board of rectangle (7) is big slightly than air inlet (6) face size, and the relative distance of the two changes the adjustment function that can realize intake.The both sides horizontal symmetrical ground vertical welding of the geometric center position on the air regulating board (7) is two pull bars (8) at a distance of 150---200mm then, stretch out outside the stove from the tie rod hole (11) of rectangle plate washer (10) setting of boiler external wall rectangular aperture.The rectangular aperture of boiler external wall is relative with air regulating board (7), and than bigger than normal being advisable of physical dimension of air regulating board (7).Rectangle plate washer (10) is with the rectangular aperture block of some screws with external wall, the medial surface of rectangle plate washer (10), be welded with and be used for the location and frame is firmly transferred the L-shaped rob support (9) of section of wind pull bar (8), the end face distance of this rob support (9) outer face and air inlet (6) is 120mm---150mm, for ease of transferring wind, can be at the affixed pull bar handle of the outer end of pull bar (8) (12), even pressure orifice plate (4) in the air compartment (1) is over against this air compartment air inlet, its upper edge side is vertically welded on the solebar angle (3) of air inlet far-end, its dual-side is welded in respectively on the air compartment side plate (2), its lower side is apart from deashing chute surface 60---80mm, bore dia on the even pressure orifice plate (4) is about 12---16mm, and hole count is about 30---50.
Dust remover control stick (14) connects the dust remover pull bar, and device is in the centre position of two pull bar handles (12).When boiler operatiopn need be transferred wind, push-and-pull pull bar handle (12), air regulating board (7) can have certain distance to change to reach accent wind purpose with air inlet (6) thereupon, because pull bar (8) level of this mechanism is installed, the different of certain gravity effect and internal stress are arranged, can make and transfer wind mechanism to have certain auto-lock function, thereby realize the convenient wind effect of transferring.After air-flow enters air compartment, meet, produce the saturating effect of loosing, can eliminate remaining dynamic pressure composition in the air-flow, impel the air compartment static balance, can improve efficiency of combustion with the even pressure air regulating board that head-on is provided with.When needing repairing, unload the some bolts on the rectangle plate washer (10), the rectangle plate washer can be pulled out together with air regulating board, pull bar, rob support, thereby got through air compartment, air channel and extraneous getting in touch, be convenient to observe, be convenient to maintenance.
This device is reasonable in design, simple in structure, materials are few, moving part is few, flexible to operation, be suitable for and boiler improvement and manufacturing, receive praises from customers.
Claims (4)
1 one kinds of even louvers of pressing of boiler, it is characterized in that air inlet (6) is relative with rectangle plate washer (10) position, horizontal symmetrical ground, both sides, the geometric center position vertical welding of air regulating board (7) is two pull bars (8) at a distance of 150---200mm then, pull bar (8) passes the tie rod hole (11) of rob support (9) and rectangle plate washer (10), it is affixed with pull bar handle (12) to stretch out boiler external wall (13), the even top of orifice plate (4) of pressing is welded in the air compartment (1), on the angle bar longeron (3) of air inlet far-end, its two oblique side welds with air compartment side plate (2) respectively, and its lower side is apart from dust remover slideway 60---80mm.
2 as claims 1 described even pressure louver, it is characterized in that described air regulating board (7) is big slightly than air inlet (6) physical dimension, and the end face distance of the end face of air inlet (6) and rob support (9) is 120---150mm.
3 as claims 1 described even pressure louver.It is characterized in that the physical dimension of the rectangular aperture of described rectangle plate washer (10) institute capping greater than air regulating board (7), the tie rod hole (11) on the rectangle plate washer (10) is concentric with pull bar (8) level of air regulating board (7).
