Abstract

The utility model relates to a cleaning device, in particular to a fan impeller cleaning device, which comprises a water inlet device and a pollution discharging device; a water inlet pipe is arranged in the water inlet device in which an atomizing nozzle which is connected with the water inlet pipe is arranged; a pollution discharging pipe which is communicated with the bottom part of the fan is arranged in the pollution discharging device; and the other end of the pollution discharging pipe is communicated with a water sealing groove. Compared with the prior art, the utility model has simple structure, and on-line cleans the impeller and the flow passage without operation stopping by using common pressure clear water; not only the cleaning effect is guaranteed, but also the long period operation of the fan is guaranteed.

Description

The draught fan impeller washing unit

Technical field:

The utility model relates to washing unit, specifically a kind of draught fan impeller washing unit.

Prior art:

Present widely used general centrifugal blower allows to carry dry, dust loading to be no more than 150mg/m ³Dust-containing airflow.Otherwise, carry moist dust-containing airflow, dust very easily adheres on impeller, scabs, cause the dynamic balancing of impeller to destroy, produce vibration, also cause that runner scabs, reduced cross-sectional area simultaneously, thus the tolerance that influence is carried, therefore carry moist dust-containing airflow to be difficult to long-term normal operation, need often to impeller and runner cleaning.Generally all shut down processing during cleaning, impeller is removed, the artificial then method that scabs of removing not only wastes time and energy but also influence normal operation.ZL95210148.3 also discloses a kind of washing unit of draught fan impeller, but this device also draught fan impeller to be pulled down, and the angle between its each nozzle and the interior cover is wayward, processing is inconvenient.

Summary of the invention:

Goal of the invention of the present utility model is at the deficiencies in the prior art, provide a kind of simple in structure, needn't dismantle impeller, draught fan impeller washing unit that cleaning performance is good.

The utility model is by the following technical solutions: this draught fan impeller washing unit, comprise water feed apparatus and drainage device, be provided with suction tude in the described water feed apparatus, the atomizer nozzle that is connected with intake pipe is housed in this suction tude, be provided with the drain pipe that is communicated with the blower fan bottom in the described drainage device, the other end of this drain pipe is communicated with seal tank.

Compared with prior art, advantage of the present utility model is: simple in structure, with the clear water of usual pressure, do not shut down on-line cleaning impeller and runner, and can guarantee cleaning performance, can guarantee the long-term operation of blower fan again.

Description of drawings:

Fig. 1 is an assembling schematic representation of the present utility model.

Fig. 2 is a water feed apparatus internal structure schematic representation of the present utility model.

Among the figure: blower fan 1, suction tude 2, atomizer nozzle 3, intake pipe 4, adpting flange 5, inlet valve 6, blowdown valve 7, drain pipe 8, seal tank 9, spill pipe 10, cleaning eye 11, connecting head 12, draught fan impeller 13.

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

Referring to accompanying drawing, in the present embodiment, this device comprises water feed apparatus and drainage device, described water feed apparatus is by suction tude 2, atomizer nozzle 3, intake pipe 4, adpting flange 5 and inlet valve 6 constitute, suction tude 2 is installed on blower fan 1 shell, in this suction tude 2, also be provided with atomizer nozzle 3, this atomizer nozzle 3 is threaded togather with connecting head 12 with the tail end of intake pipe 4, can be convenient for changing like this, check atomizer nozzle 3, the leading portion of intake pipe 4 is equipped with inlet valve 6, is installed in blower fan 1 housing outlet place, the outside of suction tude 2, so that adjust the flow of atomized water, this intake pipe 4 is also fixing with the adpting flange 5 that an end is welded on suction tude 2 outer walls, sealing;

Described drainage device is installed in the minimum point of fan outlet tube line, by blowdown valve 7, drain pipe 8, seal tank 9,, spill pipe 10 and cleaning eye 11 constitute, one end of drain pipe 8 is communicated with the bottom of blower fan 1 shell, the other end inserts seal tank 9 inside, the position, intermediate portion installs blowdown valve 7 additional, so as cleaning during seal tank 9 gas do not leak, the top of seal tank 9 is connected with spill pipe 10, its underpart also has cleaning eye 11, so that cleaning mud.

Atomizer nozzle 3 is decided according to the flow velocity of gas and the rotating speed of draught fan impeller 13 to the distance of fan impeller 13, and its height keeps concentric with draught fan impeller 13.Atomizer nozzle 3 is selected the screw type nozzle for use, and the nozzle flow channel of this structure is wide, is difficult for scabbing, and is difficult for stopping up, and does not need the pressurization atomizing.

Working procedure of the present utility model: under driven by motor, draught fan impeller 13 high speed rotating, dust-containing airflow is inhaled in the suction tude 2.After the inlet valve 6 of water feed apparatus is opened, rinse water enters in the atomizer nozzle 3, atomizer nozzle 3 ejection water smokes, together enter in the blower fan 1 with the gas in the suction tude 2, because draught fan impeller 13 high speed rotating produce centrifugal force, dust and water smoke come together in the runner after being thrown on the inner walls of blower fan 1, after sewage arrives minimum point, sewage is drained in the seal tank 9, discharge by spill pipe 10 then by drain pipe 8.Whether rinse water can select continuous wash according to the dust-laden situation, and cleaning the water yield should adapt with atomizer nozzle 3.

Because the atomizer nozzle 3 that this device adopts, need only wash water pressure and reach more than the 0.25Mpa and all clear water can be atomized, easy to use, and when using this washing unit, needn't shut down, but on-line cleaning.

Claims

1, a kind of draught fan impeller washing unit, comprise water feed apparatus and drainage device, it is characterized in that: be provided with suction tude in the described water feed apparatus, the atomizer nozzle that is connected with intake pipe is housed in this suction tude, be provided with the drain pipe that is communicated with the blower fan bottom in the described drainage device, the other end of this drain pipe is communicated with seal tank.
