Detailed Description
The technical solutions of the present invention are further explained below with reference to the accompanying drawings so as to be more easily understood and appreciated.
The utility model provides a multifunctional combined small centrifugal fan sound-proof cover which is used for covering the small centrifugal fan and preventing the noise from spreading outwards when the fan works. As shown in fig. 1 to 4, the soundproof cover of the present invention is a frame and door panel assembly structure, which is a totally enclosed three-dimensional cover body formed by first erecting 12 steel frames 13 as edges to form an upright three-dimensional structure, then fixedly assembling a left side panel 5, a right side panel 3, a rear cover plate 7 and a top cover plate 1, and finally installing a front door panel 2.
Wherein, be equipped with centrifuge's air outlet pipe mouth 11 on the right side board 3, air outlet pipe mouth 11 next door is equipped with air outlet pipe closure plate 4, be equipped with centrifuge's air inlet pipe mouth 12 on the back shroud 7, air inlet pipe mouth 12 next door is equipped with air inlet pipe closure plate 8. Preceding door plant 2 passes through hinge 9 and left side board 5 swing joint, and preceding door plant 2 right side is equipped with lock 10, like this, can open preceding door plant 2 at any time, looks over the inside condition of sound-proof housing. Further, it is also possible to provide the observation window 14 on the front door panel 2 so as to preliminarily observe the inside of the soundproof cover from the outside without opening the front door panel 2. Preferably, a heat dissipation port 6 may be further provided on the left side plate 5 in order to increase the heat dissipation effect.
The above solution solves the problems of assembly, observation, heat dissipation, etc. of sound-proof enclosures, however, the inventors found that such sound-proof enclosures have for a long time had two sound-proof dead corners, namely: the air outlet pipe of the centrifugal machine and the air outlet pipe opening of the door plate, and the air inlet pipe of the centrifugal machine and the air inlet pipe opening of the door plate. The two places are always in rigid connection, and cannot be completely sealed in size due to installation requirements. In view of this, the present inventors propose the following solution.
Two semicircular holding pads 15 are respectively lined between an air outlet pipe orifice 11 on the right side plate 3 of the multifunctional combined type small centrifugal fan sound-proof housing and an air outlet pipe of the centrifugal machine and between an air inlet pipe orifice 12 on the rear cover plate 7 and an air inlet pipe of the centrifugal machine, and the semicircular holding pads 15 are structurally shown in fig. 5 and 6. When the air conditioner is assembled, the binding surface 17 of the semicircular holding pad 15 is bound with the inner surface of the right side plate 3 or the rear cover plate 7, the semicircular lug 16 on the semicircular holding pad 15 penetrates through the air outlet pipe orifice 11 or the air inlet pipe orifice 12 from inside to outside, and the part of the semicircular lug exposed out of the right side plate 3 or the rear cover plate 7 is held tightly by a circular hoop. For convenient use, the inner diameter d of the semicircular lug 16 of the semicircular holding pad 15 is slightly larger than the outer diameter of an air outlet pipe or an air inlet pipe of the centrifuge; the outer diameter D of the semicircular lug 16 is slightly smaller than the inner diameter of the air outlet pipe orifice 11 or the air inlet pipe orifice 12; moreover, a soft damping and sound-insulating material can be arranged between the semicircular holding cushion 15 and an air outlet pipe or an air inlet pipe of the centrifugal machine, so that a better application effect can be achieved.
Because preceding door plant 2 and left side board 5 are articulated formula swing joint, can adopt ageing-resistant soft adhesive tape to seal in the front at 2 peripheries of door plant, observation window 14 can adopt double-deck doubling safety sound insulation glass, and the sound-proof housing lets lie in centrifuge's circuit and trompil, also needs to do sealing process. Such processes are commonly specified in the industry and will not be described in detail herein.
Through the above description, the soundproof cover provided by the utility model is formed by assembling the modules such as the steel frame, the side plates, the rear plate, the top plate and the front door plate, and the modules have high strength, can be repeatedly disassembled and assembled, are not easy to deform, and are safe and convenient to maintain. The sound-proof shield adopts an external insulation and internal absorption mode, so that the sound insulation and absorption quantity is large, and the heat dissipation effect is good; the side plate of the sound-proof shield is provided with a heat radiation window, so that the heat radiation of the centrifugal fan is facilitated under the condition that the sound-proof effect is not influenced; and, at the door plant and centrifuge's air-supply line and the linking position of going out the tuber pipe, adopt the semi-circular pad of embracing of original, assisted soft shock attenuation acoustic material, thoroughly stopped these two places by the sound insulation dead angle of depositing for a long time, made the effect of giving sound insulation promote by a wide margin.
While the technical solution, assembly process and implementation effect of the present invention have been described in detail, it should be noted that the description is only a typical example of the present invention, and besides, any combination of various embodiments disclosed in the present invention can be made, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
