Description
Technical Field
The utility model relates to a coiled pipe installation technical field specifically is a boiler passageway sound wave antivibration baffle device structure.
Background
The heating surface is an important component in a boiler and is a key for improving the operating environment of an equipment system, the heating surface is generally formed by a coiled pipe, the width of a flue gas channel of the boiler is small and is about 4-5 meters in a general small boiler, and the resonance basically does not occur when the boiler operates, but for a large boiler, the width of the channel is large and can reach 8-10 meters, once the karman vortex street frequency generated by a heating surface pipe bundle is close to the acoustic natural frequency of a heating surface air chamber, the resonance can occur, so that the normal operation of the boiler is influenced, and potential safety hazards exist.
Disclosure of Invention
In order to solve present heating surface because of resonance influences the boiler normal operating, there is the problem of potential safety hazard, the utility model provides a boiler passageway sound wave antivibration baffle device structure, it can prevent effectively that the heating surface pipe from taking place the sound wave resonance, ensures the operation of boiler safety and stability.
The technical scheme is as follows: the utility model provides a boiler passageway sound wave antivibration baffle device structure, its include the passageway backplate with arrange in serpentine pipe between the passageway backplate, its characterized in that, install between the passageway backplate and be located the supporting beam of serpentine pipe top, the crisscross welding in supporting beam both sides has the baffle, is less than with the interval of two adjacent baffles of one side the width of baffle, both sides the baffle forms the baffle passageway, the baffle passes adjacent two clearance and the bottom terminal surface between the serpentine pipe are less than the lowermost layer the serpentine pipe.
The corrugated pipe structure is further characterized in that a steel plate is arranged below the coiled pipe at the lowest layer, a steel plate abdicating notch is formed in the bottom of the partition plate, the steel plate penetrates through the steel plate abdicating notch, two ends of the steel plate are fixed to the coiled pipe and located on two sides of the partition plate, a limiting shaking-stopping plate is welded to the bottom of the steel plate, and a gap is reserved between the partition plate and the limiting shaking-stopping plate;
the steel plate is connected with the coiled pipe through a U-shaped bolt matched with a nut.
Adopt the utility model discloses afterwards, through a baffle on the supporting beam, separate out two regions with the drum passageway, every region has all been maintained in normal width, has changed original heating surface air chamber acoustics natural frequency, has avoided karman vortex street frequency, can effectively prevent to take place resonance phenomenon, has ensured the operation of boiler safety and stability.

FIG. 2 is a side view of FIG. 1;
FIG. 3 is a top view of a support beam;
fig. 4 is a schematic view of the steel plate relief notch.
Detailed Description
Referring to fig. 1 to 4, a sound wave vibration-proof partition plate device structure for a boiler channel comprises channel protection plates 1 and serpentine tubes 2 arranged between the channel protection plates 1, wherein a support beam 3 positioned above the serpentine tubes 2 is installed between the channel protection plates 1, partition plates 4 are welded on two sides of the support beam 3 in a staggered manner, the distance between two adjacent partition plates 4 on the same side is smaller than the width of each partition plate 4, namely, the partition plate 4 on one side is projected to the partition plate 4 on the other side to form a partition plate channel, and the partition plates 4 penetrate through the gap between two adjacent rows of serpentine tubes and are lower than the serpentine tubes on the lowest layer in the bottom end surface, so that the channel can be divided into two areas.
3 below of the coiled pipe of lower floor is provided with steel sheet 5, and 4 bottoms of baffle are equipped with the steel sheet breach of stepping down 6, and steel sheet 5 passes steel sheet breach of stepping down 6 and both ends and is fixed in coiled pipe 2, is located 4 both sides of baffle, and the welding of 5 bottoms of steel sheet has spacing shake plate 7, leaves the clearance between baffle 4 and the spacing shake plate 7 of stopping, leaves the inflation allowance when playing limiting displacement.
Specifically, the steel plate 5 and the serpentine tube 2 are connected through a U-shaped bolt 8 and a nut 9.
The utility model discloses in, supporting beam, baffle etc. can carry out reasonable selection according to passageway and heated surface size, and the adaptability is wider, can directly adopt materials such as shaped steel, steel sheet to make, and is with low costs.
