Abstract
The utility model discloses a bent-tube silencer, which comprises a casing. The casing consists of a straight line segment and an arc segment formed by bending one end of the straight line segment. The section of the casing is rectangular. The straight line segment is provided with muffler pieces inside. The casing is composed of an outer layer of steel plate, a middle layer of fiber sound-absorbing material and an inner layer of orifice plate., The bent-tube silencer with simple structure, low cost and convenient using is suitable for an air supply and distribution system of a central air conditioner, can eliminate the noise of exhaust fans and exhausters or smoke extraction systems in kitchens of hotels and catering services; and further can be used to silence an air inlet and an air outlet of a ventilation system, such as ports of an outlet end and an inlet end of an exhausting fan, and the silencer can be installed to attenuate the noise while ensuring normal ventilation, so as to achieve the purpose of eliminating noise pollution.
Description
Technical field
The utility model relates to a kind of Winding pipe silencer, belongs to the silencing apparatus technical field.
Background technique
At present, for the ease of realizing the interior separate ventilation of machine room, generally all adopt and on exterior wall, open vent hole and blower fan is installed is carried out forced ventilation, but behind the installation blower fan, other noise in fan noise and the machine room will be by vent hole to external radiation, external environmemt is caused noise pollution, also do not have a equipment of eliminating the noise at this noise like specially to occur on the existing market, though some large-scale silencing apparatuss are arranged but because its complicated structure makes cost higher, the noise elimination effect is not good yet, and can not well install, stable inadequately after the installation, drop easily, the ventilated port of existing silencing apparatus size is fixing in addition, can not set according to the size in on-the-spot air port, versatility is not strong, therefore, existing silencing apparatus can not adapt to people's needs, is badly in need of improving.
The model utility content
At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of Winding pipe silencer for the solution machine room can reduce or eliminate noise pollution in interior separate ventilation, can effectively solve the problem that above-mentioned prior art exists.
To achieve these goals, the technical solution adopted in the utility model is: disclose a kind of Winding pipe silencer, it comprises shell, shell is made of the arc section that straightway and one end end bent form, the cross section of described shell is a rectangle, be provided with anechoic sheet in the straightway of shell, described shell is made up of the fiber sound-absorbing material layer in outer field steel plate, middle level and the orifice plate of internal layer.
As preferably, described anechoic sheet laterally or vertical the setting and is fastenedly connected with the inwall of shell.
The beneficial effect that this model utility is brought is: simple in structure, the low cost of manufacture of this model utility, and convenient the use possesses following advantages: 1,, be convenient to install by wall owing to used the bend pipe form, reliable and stable.2, owing to be that bend pipe makes noise avoid direct projection, increased positive sound absorption, sound insulation, sound deadening capacity is increased.3, corner is an arc transition, and it is little that air communication is crossed resistance.4, can press the size coupling silencing apparatus of vent hole, its highly versatile.Therefore, this Winding pipe silencer is applicable to for blowing system, eliminate building pumping, ventilation machine noise, hotel, catering trade kitchen pump drainage cigarette System noise, the intake grill and the exhaust port that also can be ventilation system are eliminated the noise, as be configured in the port of ventilating fan outlet and inlet, can make after the installation and ventilate normally simultaneously with noise attentuation, to reach the purpose of final elimination noise pollution.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Shown in Fig. 1-2, as a kind of embodiment of the present utility model, this Winding pipe silencer comprises shell 1, shell 1 is made of the arc section that straightway and one end end bent form, the cross section of shell 1 is a rectangle, in the present embodiment, the cross section of shell 1 is a square, and the length of described shell 1 equals four times of its cross section square length of side.Be provided with anechoic sheet 2 in the straightway of shell 1, anechoic sheet 2 can be laterally or vertical the setting, and be fastenedly connected with the inwall of shell 1.Described shell 1 is made up of outer field steel plate 11, the fiber sound-absorbing material layer 12 of middle level filling and the orifice plate 13 of internal layer, and specifically, internal layer is that thickness is the steel plate materials of 0.5-0.75mm, has perforation on the steel plate materials, and its punching rate can reach 20%～25%; The middle level is an absorbent treatment, is coated with glass fiber cloth by lamination coating to form; Outer for thickness is the steel plate of 0.75-2mm, its combination connecting mode can adopt the mode that detachably is fastenedly connected of screw, rivet, also can adopt the means of fixation of welding to realize.During use, whole Winding pipe silencer can be connected with body of wall with angle steel, and the link that is adopted during connection is selected EXPANSION ANCHOR BOLTS for use.
