Abstract
The utility model discloses a soot blower for a draught fan of a boiler. A main compressed air pipeline is fixedly communicated with a plurality of connecting hoses and is fixedly connected with a main air blowpipe; the main air blowpipe is fixed and supported by a bracket; from a draught fan shell, the main air blowpipe extends into and is arranged in the shaft center of a draught fan vane wheel along the direction of a draught fan shaft through a draught fan air deflector; a plurality of blowing nozzles are arranged on the main air blowpipe; and the air deflector is arranged at the front end of the center of the draught fan vane wheel. The soot blower for the draught fan of the boiler has the advantages of simple structure, high convenience and practicability, lower manufacturing cost, high durability, safety and reliability, easy installation and broad range of application. The soot blower for the draught fan of the boiler is characterized by reasonable design, as blowing is carried out from the inside to the outside, the direction of air stream generated by the blowing nozzle is identical with the direction of air stream in the draught fan, the strength of the blown air stream is not weakened but enhanced, the effect is greatly improved in comparison with the mode of blowing from the outside to the inside, and the soot blowing mode is applicable to all hot draught fans with blades designed to take special shapes.
Description
Technical field
The utility model relates to a kind of boiler induced-draft fan device, especially a kind of boiler induced-draft fan soot blower.
Background technique
At present, the shortcoming of boiler induced-draft fan soot blower is on the market: in addition, because its driving device structure complexity, so when cradle is installed, need professional workforce's guiding work, and cost is higher.
At present, the supply of heat energy generally all is to rely on the waste material stove in the middle of the middle-high density board assembly line enterprise, and fuel is taken from the self-produced in process of production wooden waste of production line.Its shortcoming is: the waste material stove is because fuel itself is exactly powdery, and the sand grains that drops when in the middle of these powdered materialss, also containing abrasive band sand formation cuttings plate, these reasons have caused the central easy dust stratification of a lot of equipment that uses of waste material stove, and especially some blade shapes design more special blower fan, just easy dust stratification in the middle of the not plane on the blade, in case and dust stratification, balance when influencing fan operation produces vibration, as not handling, very easily equipment is damaged, even lead to great equipment accident; If but frequent shutdown handles, again to the stable adverse effect that causes of the operation and the production of stove, so, this class induced draught fan of general external import, the all supporting blade soot blower that is equipped with, purpose is when vane dust deposition, just can dispose the dust stratification on the blade under non-stop-machine situation; The mode that present these soot blowers blow ash all is that blowing nozzle is external, and gas blows from impeller axle center, blade lateral, and it is undesirable that this mode is blown grey effect, can not fundamentally solve the problem that vane dust deposition causes fan vibration.
The model utility content
The purpose of this utility model provides a kind of simple in structure, convenient and practical, boiler induced-draft fan soot blower that cost is lower, not only solved the problem that vane dust deposition causes fan vibration, and is durable in use, safe and reliable, and install easily, using scope is wide.
For solving the problems of the technologies described above, the technical solution of the utility model is:
This boiler induced-draft fan soot blower comprises: draught fan impeller, blower fan axle, flow blower casing, main air pipeline are connected the fixing connection of flexible pipe with many, it is fixedlyed connected with main gas blow pipe; Main gas blow pipe is by the carriage fixed support; Main gas blow pipe is provided with from the axle center that flow blower casing extend into draught fan impeller through the air guide sleeve of blower fan along the direction of blower fan axle; Main gas blow pipe is provided with a plurality of blowing nozzles; The hub head end of draught fan impeller is provided with air guide sleeve.
Main gas blow pipe is fixedlyed connected with flow blower casing.
The main air pipeline is fixedlyed connected with gas holder, and one section bigger air blowing tolerance can be arranged when guaranteeing to blow within a certain period of time.
The beneficial effects of the utility model:
This model utility is a kind of simple in structure, convenient and practical, boiler induced-draft fan soot blower that cost is lower, not only durable in use, safe and reliable, install easily and using scope wide, characteristics of the present utility model are reasonable in design, because outwards blow from the lining, the airflow direction that blowing nozzle produces is identical with the airflow direction of blower fan inside, the dynamics of air blowing air-flow is not weakened also to be enhanced, and the mode that effect is blown more from outside to inside improves greatly.Thisly blow the hot induced draught fan that grey mode is fit to all Blade Design that special shape is arranged and use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a composite structure schematic representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
According to Fig. 1-shown in Figure 2, the utility model mainly comprises: draught fan impeller 1, connect flexible pipe 2, main air pipeline 3, blowing nozzle 4, air guide sleeve 5, flow blower casing 6, main gas blow pipe 7, blower fan axle 8.
Main gas blow pipe 7 is fixedlyed connected with flow blower casing 6.
Working principle: this product is a kind of device of outwards blowing from the impeller center along radial direction, can effectively remove the dust stratification on the blade.Structure characteristic of the present utility model is gas blow pipe of design, extends the center of draught fan impeller from draught fan impeller air guide sleeve airintake direction, and blowing nozzle is blown facing to blade outwardly.Supporting scavenger system needs a gas holder, and one section bigger air blowing tolerance can be arranged when guaranteeing to blow within a certain period of time.The utility model design is fairly simple, blows and is responsible for by bracket support, along the blower fan axle direction, through the air guide sleeve of blower fan, extend into the axle center of draught fan impeller from flow blower casing always, some blowing nozzles air blowings is set blowing to be responsible for.
