The invention discloses a kind of box corrosive resistant fans of sound insulation, and including the cabinet outside blower and blower, the cabinet is equipped with air inlet and air outlet, and connects with the air inlet of the blower and air outlet, and the cabinet wall is equipped with egg acoustical cotton, and is equipped with thermovent.The noise generated when the present invention is using sound proof box isolation fan operation, absorbs sound wave using egg acoustical cotton, to reduce noise, does not influence surrounding resident life, while doing a protection to equipment, extends the service life of blower.
Description
Technical field
The present invention relates to field of electromechanical equipment, more particularly to a kind of box corrosive resistant fan of sound insulation.
Background technique
Blower is widely used in the ventilation, dust discharge and cooling of factory, mine, tunnel, cooling tower, vehicle, ship 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 baking of cereal
It does and selects and recommends, inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc..Existing blower is there are noiseless barrier, and noise is big when work,
The problems such as unit unprotect, service life is short.
Summary of the invention
The object of the present invention is to provide a kind of box corrosive resistant fans of sound insulation, to solve the above-mentioned problems of the prior art,
It reduces blower by noise in use, while blower is protected, prolong the service life.
To achieve the above object, the present invention provides following schemes:
The present invention provides a kind of box corrosive resistant fan of sound insulation, and including the cabinet outside blower and blower, the cabinet is equipped with
Air inlet and air outlet, and connect with the air inlet of the blower and air outlet, the cabinet wall is equipped with egg acoustical cotton, and
Equipped with thermovent.
Preferably, the thermovent is shutter, is set as two, one high and one low.
Preferably, the blower is mounted on the base by crash roll, and the cabinet is equipped on the pedestal.
Preferably, the egg acoustical cotton is adhesive on the cabinet wall.
Preferably, the cabinet is plastic material.
Preferably, the egg acoustical cotton with a thickness of 30-50mm.
The present invention achieves following advantageous effects compared with the existing technology:
The box corrosive resistant fan of sound insulation provided by the invention makes blower in bad working environments by the way that cabinet is arranged outside blower
It is used under environment, service life of fan can be allowed longer, while egg acoustical cotton is set in cabinet wall, sound wave incident is to wherein
When, a part can be converted to thermal energy and be consumed, and reduce noise, and the thermal energy of generation can be dispersed into cabinet by shutter
Outside, of simple structure and strong practicability reduce the noise because generating under nominal situation, change in work because of dry sound bring occupation
Injury.
Detailed description of the invention
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to institute in embodiment
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the invention
Example, for those of ordinary skill in the art, without any creative labor, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is the internal structure chart of interval sound box type corrosive resistant fan of the present invention；
Fig. 2 is the top view of interval sound box type corrosive resistant fan of the present invention；
Fig. 3 is the structure chart of interval sound box type corrosive resistant fan cabinet wall of the present invention.
In figure: 1: blower, 2: cabinet, 3: shutter, 4: pedestal, 5: crash roll, 6: egg acoustical cotton.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of box corrosive resistant fan of sound insulation, solutions
The certainly noise that blower is generated by itself operating, the noise generated when completely cutting off fan operation using sound proof box, so that noise is reduced,
Surrounding resident life is not influenced, while a protection is done to equipment.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Embodiment 1:
The present embodiment provides a kind of box corrosive resistant fans of sound insulation, as shown in Figure 1-3, include the cabinet outside blower 1 and blower
2, the cabinet 2 is equipped with air inlet and air outlet, and connect with the air inlet of the blower 1 and air outlet, in the cabinet 2
Wall is equipped with egg acoustical cotton 6, and is equipped with thermovent.
The words such as setting, connection, guiding connection between each component described in invention, not to specific connection type
Be defined, as long as can be operated after connection purpose and connection can be played both can, many fixed connect exists in the prior art
It connects or movable connection method, so not doing specific open and limiting.
Specifically, cabinet 2 is plastic material, and lighter weight also can choose the other materials such as plank, using size according to
The external dimensions of blower 1 designs, and blower 1 is covered on inside cabinet 2, and there are the gap of setting puigging, puigging uses chicken
Egg acoustical cotton 6 is adhesive in 2 inside of cabinet with a thickness of 30-50mm and preferably uses 40mm, egg type acoustical cotton 6 is by spy
Different processing forms a kind of sponge material of the concave-convex wave-like of one side, internal to be full of small spaces and half open-celled structure, has
The hole and bubble of a large amount of inside and outside connection, when sound wave incident to wherein when, air vibration in gap can be caused；Due to gluing for air
The friction of resistance hysteresis, air and hole wall enables quite a few sound to be converted to thermal energy and be consumed.In addition, working as air adiabatic pressure
When contracting, heat exchange constantly occurs between air and hole wall, due to conduction of heat, also a part of sound can be enable to be converted to thermal energy,
Therefore, thermovent is additionally provided on cabinet, thermovent is two shutters 3, one high and one low to be arranged in 2 side of cabinet, by motor
Outside the heat that turn generates and the thermal energy of conversion discharge case.
When installation, blower 1 is mounted on the base by crash roll 5, and cabinet 2 covers above pedestal 4, and blower 1 is covered completely
Firmly, the air inlet of blower 1 passes through cushion with the air outlet of cabinet 2 with the air outlet of air inlet, blower 1 on cabinet 2 and connect,
Prevent the vibration of cabinet 2 from influencing erasure effect.
The box corrosive resistant fan of sound insulation of the invention in the running, can largely reduce the propagation that sound is externally situated between, warp
It is qualified to cross building building air-borne sound oise insulation factor laboratory measurement report detection, simultaneously because the protection of cabinet, in bad working environments ring
It is used under border, service life of fan can be allowed longer.
Invention applies a specific example illustrates the principle and implementation of the invention, above embodiments are said
It is bright to be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art, foundation
Thought of the invention, there will be changes in the specific implementation manner and application range.To sum up, the content of the present specification should not manage
Solution is limitation of the present invention.
