Service life of the draught fan can be prolonged, so a problem of excessive vibration of a bearing seat due to imbalance of impeller rotation can be solved; a bearing can be protected from damage; maintenance and cleaning time can be shortened; and offstream possibility of equipment can be reduced.
Description
Technical field
The utility model relates to a kind of induced draught fan, particularly relates to a kind of induced draught fan washing unit.
Background technique
Induced draught fan is the blower fan of for overcoming flue resistance, flue gas being sent into chimney.Induced draught fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Induced draught fan is widely used in ventilation, the dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building; The ventilation of boiler and industrial furnace and air inducing; Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance; The oven dry of cereal and selecting and recommending; Inflation and the propelling etc. of wind-tunnel wind regime and Hovercraft.
In industrial or agricultural and people's life, all can use various boilers at present, these boilers all can produce flue gas soot emissions in atmosphere, the harmful matter that contains befouling environment more or less in flue gas flue dust, therefore to strengthen dedusting pollution treatment processing, for preventing the refluence of flue gas, install blower unit additional, but existing blower unit forms closed shape in flue simultaneously, when blower unit quits work, cause flue blockage, hindered the discharge naturally of flue gas.In addition, coal-fired process burning, is close to the dust of generation on draught fan impeller, and the dynamic balancing of induced draught fan is impacted, induced draught fan is shaken in the running, dust is more, and dust on impeller is more, causes vibrations larger, when serious, can make the lower margin of induced draught fan loosening, bearing damage, impacts the safe operation of boiler safety.
Model utility content
The shortcoming of prior art in view of the above; the purpose of this utility model is to provide a kind of induced draught fan washing unit; this device can extend induced draught fan working life; avoid the excessive problem of vibration of bearings causing because dynamic balance of impeller is destroyed; and protect bearing; prevent that bearing from suffering damage, shorten maintenance clean time, the generation of minimizing equipment stoppage in transit situation.
For achieving the above object and other relevant objects, the utility model provides a kind of induced draught fan washing unit, induced draught fan comprises casing and the impeller of being located at described casing inside, and the top of described casing is provided with the intake pipe being connected with water source, and the bottom of described casing is provided with waste pipe.
Further, described intake pipe is provided with inlet valve.
Preferably, described intake pipe is provided with drain valve.
As mentioned above, induced draught fan washing unit described in the utility model has solved after Impeller Ash Accretion of Induced Draft Fan incrustation, induced draught fan is due to the unbalance damage to equipment of dynamic balancing, avoid taking a lot of work while manually rooting out, time-consuming and remove inhomogeneous shortcoming, and avoided the threat causing to operator's person safety.

Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.
Refer to Fig. 1 to Fig. 2.Notice, appended graphic the illustrated structure of this specification, ratio, size etc., all contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
Fig. 1 is shown as the impeller 2 that the utility model induced draught fan comprises casing 1 and described casing 1 inside, and the top of casing 1 is provided with the intake pipe 3 being connected with water source, and the bottom of casing 1 is provided with waste pipe 4.This washing unit is connected with water source, can utilize waterpower and wind-force by the dust soil release of building up on Vanes on Induced Draft Fan, extends the working life of induced draught fan.
This induced draught fan washing unit intake pipe 3 is provided with inlet valve 5, can control the water yield that enters casing 1 inside, waste pipe 4 is provided with drain valve 6, can control the water displacement of casing 1 inner waste water, and whether the blade that can pass through discharged examination of wastewater impeller 2 cleans up.
Induced draught fan is generally used for industrial and mineral industry, is used in conjunction with boiler, and the intake grill of casing 1 and the flue outlet of body of heater of induced draught fan are connected, and the outlet of induced draught fan is connected with chimney, is also provided with the drive unit that impeller 2 is rotated in induced draught fan.
When concrete enforcement, first in perforate above casing 1, in hole, pack intake pipe 3 into, intake pipe 3 one end are connected with casing 1, the other end is connected with water source, be used for to the interior injection clear water of casing 1, the present embodiment arranges dress pipeline valve simultaneously as inlet valve 5 on intake pipe 3, and inlet valve 5 can be controlled inflow and flow easily; Subsequently in casing 1 bottom opening, in hole, pack waste pipe 4 into, the present embodiment arranges dress pipeline valve simultaneously as drain valve 6 on waste pipe 4, drain valve 6 can be controlled water in casing from the interior discharge of casing 1, and can whether clean up according to the water examination impeller of discharged water 2, so just complete the installation to induced draught fan washing unit.
In daily operation, water is injected in casing 1 from intake pipe 3, when water level in casing 1 arrives 1/2 position of impeller 2 height, open induced draught fan, impeller 2 is rotated in water high speed, utilize centrifugal force that the impurity on impeller 2 is removed clean, and utilize wind-force to extract out from flue simultaneously, the impurity of rapidly impeller 2 surfaces being built up cleans up.In manufacturing process, can opening water discharge valve 6, by flowing out the cleaning situation of water examination impeller 2 of waste water of waste pipe 4, to carry out subsequent operation.
In sum, a kind of induced draught fan washing unit of the utility model, has solved after Impeller Ash Accretion of Induced Draft Fan incrustation, and induced draught fan is due to the unbalance damage to equipment of dynamic balancing, avoid taking a lot of work while manually rooting out, time-consuming and remove inhomogeneous shortcoming, and avoided the threat causing to operator's person safety, and this apparatus structure is simple, installation, easy to use, with low cost, the dust impurity of assembling on impeller 1 is removed totally safe, reliable and effectively, and reusable, and utilization ratio is high.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
