Abstract
The utility model discloses a disk-type silencer, which comprises a cylindrical casing with a sealed end and an open end. A flange is arranged at the open end of the casing, a plurality of rows of air inlet grooves are annularly arranged on the circumference of the casing, filters are arranged at positions corresponding to the air inlet grooves of the casing, and damping sections are arranged close to the flange position inside the casing and communicated with the flange. A plurality of ventilation holes are evenly distributed on the cross sections of the damping sections. A damping foam pad is arranged at the end opposite to the flange of the casing. Compared with a traditional disk-type silencer adopting two mutually embedded casings, the disk-type silencer not only simplifies the structure, but also greatly reduces manufacturing cost due to the integral casing of the disk-type silencer, simultaneously, the filters arranged at the positions of the air inlet grooves can effectively filter impurities in air to lead combustion of a combustor to be more stable and effective, and additionally, the damping sections with the structures having the evenly distributed through holes favor more stable and even air flow entering the combustor.
Description
Technical field
The utility model relates to a kind of disc type silencing apparatus, is used for combustor blast machine intake grill and handles as the noise elimination of blower fan.
Background technique
Existing disc type silencing apparatus has two usually and inlays the housing that closes mutually, and ring is established the plurality of rows vent hole on housing, and is provided with muffler material in housing.Be provided with regulator between two housings that edge closes mutually and can regulate two cooperate degrees between the housing, with the quantity of adjusting vent hole, and then the ventilation of regulating the combustor blast machine.Adopt the disc type silencing apparatus of this form, its structure is complicated, and fabricating cost is also higher, regulates the ventilation better effects if of blower in fact by air-valve.Simultaneously, blower sucks impurity such as some dusts easily, has influenced the burning of burner, when serious, even can cause the fault of burner.
The model utility content
For overcoming above-mentioned defective, the utility model aims to provide a kind of simple in structure, the combustor blast machine disc type silencing apparatus that fabricating cost is low, and it also has the effect of filtered air simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of disc type silencing apparatus, it comprises a housing, described housing is end sealing, the tubular of an end opening, and the opening end of described housing has flange edge, be equipped with the plurality of rows air intake duct on the circumference of described housing, described housing is provided with filter with respect to the air intake duct place, is provided with muffler section near the flange edge place in the described housing, and described muffler section and flange edge connect.
Be evenly distributed with several vent holes on the cross section of described muffler section.
Described housing is provided with the noise elimination foam pad with respect to an end of flange edge.
Adopted disc type silencing apparatus of the present utility model, because its housing adopts integrated type, compare with the housing that traditional disc type silencing apparatus adopts two mutual edges to close, designs simplification not only, and fabricating cost also reduces greatly, simultaneously, the filter that is provided with at the air intake duct place is the impurity in the filtered air effectively, makes the burning of burner effectively stable more.In addition, adopt air-flow that the muffler section be evenly distributed with several vent hole structures helps entering burner more steadily evenly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a muffler section cross section structure schematic representation of the present utility model.
Among the figure: 1-housing, 2-flange edge, 3-air intake duct, 4-filter, 5-muffler section, 6-vent hole, 7-noise elimination foam pad.
Embodiment
As depicted in figs. 1 and 2, this practicality discloses a kind of disc type silencing apparatus, it is characterized in that it comprises a housing 1, described housing 1 is end sealing, the tubular of one end opening, the opening end of described housing 1 has flange edge 2, be equipped with plurality of rows air intake duct 3 on the circumference of described housing 1, described housing 1 is provided with filter 4 with respect to air intake duct 3 places, usually the structure of filter 4 is the nonwovens of support cloth on Steel Bracket, be provided with muffler section 5 near flange edge 1 place in the described housing 1, described muffler section 5 connects with flange edge 1.When blower was worked, air communication was crossed air intake duct 3 and is entered in the housing 1, and through entering muffler section 5 after filter 4 filtrations, high speed airflow noise through muffler section 5 time is absorbed and reduces.Reached noise elimination effect to the blower air intake.
More even for the air-flow that makes the blower air intake, be evenly distributed with several vent holes 6 on the cross section of described muffler section 5.High velocity air in entering housing 1 is when flowing through muffler section 5, and air-flow is evenly distributed with on the muffler section 5 that several vent holes 6 are divided equally and the air-flow that forms uniform and stable.
In order to make the noise elimination better effects if of disc type silencing apparatus of the present utility model, described housing 1 is provided with noise elimination foam pad 7 with respect to an end of flange edge 1.
