Abstract
The present invention relates to a blower capable of preventing dust accumulation on blades, which comprises a blower shell. The blower has the following characteristics: a non-working surface weeper for the blower blades is arranged in the blower shell; and the structure of the non-working surface weeper for the blower blades is as follows: a fixed air distribution tube and an air distribution tube connected with the fixed air distribution tube are arranged on the blower shell, and a plurality of nozzles are arranged on the air distribution tube. The included angle between the central lines of the nozzles and the blades are 75 degrees to 86 degrees. An adjustor is arranged on the air inlet of the fixed air distribution tube; an actuating mechanism is arranged on the air distribution tube; and the air outlet of the blower shell is provided with an air volume sensor. A falling sand bucket is arranged on the fixed air distribution tube. The owned pressure head of the blower is utilized to suck part of the air into the air distribution tube of the weeper, then, the nozzles arranged on the air distribution tube spray the air onto the non-working surfaces of the blades, the blades are swept once one by one as a vane wheel rotates once, and therefore dust can be prevented from being accumulated on the non-working surfaces. The blower has the advantages of simple structure, safe use, long service life, etc.
Description
Technical field
The present invention relates to blower fan, is a kind of vane dust deposition formula blower fan that prevents.
Background technique
Existing centrifugal blower and axial fan are most widely used blower fans in the industrial enterprise.The blade shape of blower fan has plate and two kinds of forms of wing blade, often makes airfoil blade for large fan, and that small-sized fan is generally made is plate.In the blower fan working procedure, no matter its blade of blower fan of which kind of blade shape all has the branch of working surface and non-working surface, if work under dust-contained airflow, its working surface can wear and tear because of the impact of solid particle, and its non-working surface can under the effect of eddy current dust stratification take place.When the part dust stratification comes off in the blower fan rotation process, will cause fan vibration, can extract the blower fan stone bolt during serious vibration, make blower fan generation catastrophe failure.
Summary of the invention
Technical problem to be solved by this invention is that the vane dust deposition formula that prevents blower fan a kind of simple in structure, safe in utilization, that the life-span is long is provided.
Solving the technological scheme that its technical problem adopts is, a kind of vane dust deposition formula blower fan that prevents, it comprises Blower Housing, it is characterized in that: the non-working surface blowing cleaner that in Blower Housing, is provided with fan blade, the structure of the non-working surface blowing cleaner of described fan blade is, on Blower Housing, be provided with fixedly aid distributing pipe and coupled aid distributing pipe, on described aid distributing pipe, be provided with several nozzles.
The center line of described nozzle and the angle between the blade are 75～86 °.
On the intake grill of described fixedly aid distributing pipe, be provided with regulator, on described aid distributing pipe, be provided with actuator, be equipped with air flow sensor at the exhaust outlet of Blower Housing.
On described fixedly aid distributing pipe, be provided with the knockout bucket.
The advantage applies of vane dust deposition formula blower fan that prevents of the present invention exists:
1. utilize fixedly aid distributing pipe and the connected aid distributing pipe of the pressure head of blower fan itself with the non-working surface blowing cleaner of a part of gas suction fan blade, several nozzle ejection that are provided with from aid distributing pipe are to the non-working surface of blade again, impeller whenever circles, blade is purged one time successively, prevent that dust deposit is on the non-working surface of blade thereby reach, this device is applicable to self negative pressure than higher induced draught fan, suction gas flow can regulate; Signal is sent to the regulator that on the intake grill of aid distributing pipe, is provided with according to the size of the blower fan load air flow sensor by fan outlet, regulator control executing mechanism online adjustment aid distributing pipe deflection angle and make the best angle to the gas flow purging of blade non-working surface of several nozzle ejection on the aid distributing pipe guarantees that blower fan works in the best condition.
2. the negative pressure of utilizing blower fan self to produce, draw the air of environment or the higher gas of pressure of blower fan outlet, can introduce in the nozzle of fan blade inlet by special pipeline, air communication is crossed the nozzle high velocity jet to fan blade dust stratification surface, prevent that dust from depositing the purpose of thickening on blade thereby reach, avoid because the abnormal condition that dust stratification causes the blower fan power consumption to increase to be vibrated with rotating part occurs.
3. can fixedly on the aid distributing pipe knockout bucket be installed, add an amount of fine sand in the bucket, and when fan vibration sand is put into pipe, the people is the state that causes a kind of wearing and tearing, with the dust stratification on the high speed fine sand impact blades, to reach the purpose of deashing, vibrationproof.
5. have advantages such as simple in structure, safe in utilization, that the life-span is long.

Among the figure: 1-Blower Housing, 2-blade, 3-inlet baffle, 4-regulator, 5-actuator, 6-blower fan axle, 7-air flow sensor, 8 aid distributing pipes, 9 nozzles, the 10 husky buckets that fall, 11 fixing aid distributing pipes.
Embodiment
The invention will be further described to utilize drawings and Examples below.
With reference to Fig. 1-3, prevent that vane dust deposition formula blower fan from being that its blower fan structure is same as the prior art to the improvement of existing blower fan, its structure is to have Blower Housing 1, is provided with blower fan axle 6 in Blower Housing 1, is provided with blade 2 and inlet baffle 3 on blower fan axle 6.On Blower Housing 1, be provided with the non-working surface blowing cleaner of fan blade, the structure of the non-working surface blowing cleaner of described fan blade is, on Blower Housing 1, be provided with fixedly aid distributing pipe 11 and coupled aid distributing pipe 8, on described aid distributing pipe 8, be provided with several nozzles 9.On the intake grill of fixing aid distributing pipe 11, be provided with regulator 4, on aid distributing pipe 8, be provided with actuator 5, be equipped with air flow sensor 7 at the exhaust outlet of Blower Housing 1.Control mode adopts prior art.
The vane dust deposition blower fan that prevents of the present invention, through 10 months probationary certificates have blade not dust stratification, Use the advantages such as safety, life-span length.
