Abstract
The utility model relates to a kind of dust-proof blowers, including spiral case, the spiral case is equipped with air inlet and air outlet, it is characterized in that the air inlet wall extension with outward extension, the wall extension is equipped with dust board, and the wall extension is equipped with cover board, and the cover board is equipped with air inlet, the air inlet is equipped with outwardly extending accelerated passage, and the path length of the dust board is greater than the path length of the air inlet；Using in dust-proof blower of the program compared to existing setting filter screen, influence to power of fan is smaller, and durable, and furthermore wind-force when blower running is bigger, dust-proof effect is better, and conventional fan is but unable to reach better dust-proof effect when wind-force is big.
Description
Technical field
The utility model relates to mechanical manufacturing fields, and in particular to a kind of dust-proof blower.
Background technique
Blower can inevitably absorb the particulate matter in air in the process of work, therefore be easy to cause to processing substance
Air blast is carried out during polluting, for example carry out forced air drying to food in food processing, is easy to pollute food, it is existing
Have in technology and filter screen usually is arranged to air blower, but filter screen is set and seals the working efficiency for being easy to influence air blower, and
And air blower wind-force it is excessive be easy filter screen is caused to be lost, particulate matter hit filter screen also will affect filter screen use the longevity
It orders, furthermore the readily permeable filter screen of wind-force oversized particles object, so that filter effect is influenced, in consideration of it, the inventor of this case designs
A kind of dust-proof blower, can should not filter screen just can reach dust-proof effect.
Utility model content
In order to solve the above problem, the utility model is achieved through the following technical solutions:
A kind of dust-proof blower, including spiral case, the spiral case are equipped with air inlet and air outlet, it is characterised in that the air inlet
Wall extension with outward extension, the wall extension are equipped with dust board by connecting rod, and the wall extension is equipped with cover board, the cover board
It is equipped with air inlet, the air inlet is equipped with outwardly extending accelerated passage, and the path length of the dust board is greater than the air inlet
The path length of mouth.
Further, dust board is equipped with inner groovy, is equipped with dust exhaust apparatus in the inner groovy.
Further.Wall extension and the removable connection of the cover board.
Preferably, the bore of air inlet is the 1/3-2/3 of the bore of dust board.
Preferably, the length of accelerated passage is 20-50cm.
The utility model has the advantages that the particulate matter outside the work of dust-proof blower can be sucked among blower, carried out in accelerated passage
Lasting to accelerate, particulate matter can generate higher kinetic energy, can directly impinge upon on dust board, be inhaled when moving to baffle
Dirt device is adsorbed, so that it is dust-proof to achieve the effect that blower integrally.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the utility model internal structure chart；
Fig. 3 is the utility model sectional view.
Appended drawing reference is as follows:
1, spiral case；2, air inlet；3, air outlet；4, wall extension；5, dust board；51, inner groovy；52, dust exhaust apparatus；6, it covers
Plate；7, air inlet；8, accelerated passage.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, it should be understood that this is practical new
The structure of type is not limited in following embodiment:
As shown in Figure 1-3, a kind of dust-proof blower, including spiral case 1, the spiral case 1 is equipped with air inlet 2 and air outlet 3, special
Sign is that the air inlet 2 wall extension 4 with outward extension, the wall extension 4 are equipped with dust board 5, and the wall extension 4 is set
There is cover board 6, the cover board 6 is equipped with air inlet 7, and the air inlet 7 is equipped with outwardly extending accelerated passage 8, the dust-break
The path length of plate 5 is greater than the path length of the air inlet 7.When dust-proof blower is worked, it can be inconjunction with and absorb in air
Particulate matter can be affected by the wind when through accelerated passage 8 and persistently add since particulate matter has certain quality
Speed, to obtain higher kinetic energy, when particle moves to wind deflector, particulate matter kinetic energy is excessive and path is less likely to occur
It deviates and turns, so that 5 top of dust board is impinged upon, to achieve the effect that dust-proof；And the program is dust-proof compared to traditional
Blower, due to being not provided with filter screen, so as to so that blower can obtain higher power, and traditional blower wind-force is got over
The effect of big filter screen is smaller, and in the program, the kinetic energy that wind-force more large particle obtains in accelerated passage 8 is bigger, thus
It is easier to impinge upon on dust board 5, therefore dust-proof effect is better.
Further, dust board 5 is equipped with inner groovy 51, is equipped with dust exhaust apparatus 52 in the inner groovy 51；Using the program,
Particulate matter can be adsorbed by dust exhaust apparatus 52, prevents particulate matter from falling from dust board 5 to cause secondary pollution, preferably
, dust exhaust apparatus 52 can be using dust attractant materials such as dust suction cottons.
Further.Wall extension 4 and the removable connection of the cover board 6, using the program, when dust attractant materials adsorb excessively
When particulate matter, cover board 6 can be dismantled and replace dust exhaust apparatus 52；A kind of feasible connection type is exactly in extension and cover board
Mounting hole is arranged in the end face of contact, and corresponding aperture is arranged in cover board, is then connected by peg.
Preferably, the bore of air inlet 7 is the 1/3-2/3 of the bore of dust board 5；The length of accelerated passage 8 is 20-
50cm.Good dust-proof effect can achieve using the program.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Ability
The technology people in domain is described in the above embodiment and specification it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also
There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted
Protection scope is asked to be defined by the appending claims and its equivalent thereof.
