Abstract
The utility model discloses an airing muffler of a soundproof shield for an electric furnace, which comprises a sound eliminating element (1), a sound eliminating channel (3) and a shell (6), wherein the shell (6) is composed of an outer shell (4), a rib plate (5) and a flange (7); and the sound eliminating element (1) is composed of a skeleton and sound eliminating material (2). The utility model is characterized in that at least one sound eliminating channel (3) is arranged in the inner chamber of the shell (6); the skeleton of the sound eliminating element (1) is sealed by a sound absorbing plate made of glass fabric after the sound eliminating material (2) is filled in the skeleton. The sound eliminating channel (3) is in a fold line or wave structure. The sound eliminating material (2) is made by mixing sound eliminating materials with different volume weights. The utility model has simple and reasonable structure, can obviously reduce noise, and is suitable for industrial electric furnace rooms when in noise prevention.
Description
Technical field
The utility model relates to a kind of environment-friendly products, particularly relates to a kind of electric furnace acoustic hood ventilation silencer.
Background technology
The industrial furnace that mechanical industry is used has polytype, in foundry, the furnace cupola, induction furnace, resistance furnace, electric arc furnaces, vacuum drying oven, open hearth, crucible furnace of smelting metal etc. is arranged; Mold drying oven, ferroalloy baker and foundry goods annealing furnace etc. that the baking sand mold is arranged; In the forging and pressing workshop, there are pair steel ingot or steel billet to forge the heat-treatment furnace that eliminates stress after preceding various heating furnaces that heat and the forging; In the metal heat treatmet workshop, the heat-treatment furnace of the various annealing, normalizing, quenching and the tempering that improve the workpiece mechanical performance is arranged; At welding shop, the weld preheating stove and the postwelding tempering furnace of weldment arranged; The heating furnace of sintering metal etc. is arranged in the powder metallurgy workshop.Industrial furnace also is widely used in other industry, as Metal Melting furnace, ore sintering stove and the coke oven of metallurgical industry; The retort of petroleum industry and cracking funace; The producer of gas industry; The cement kiln of silicate industry and glass melting, glass oven; The oven of food industry etc.Industrial furnace not only can be divided into two classes by thermal regulation: a class is the discontinuous stove but also claims the periodic stove, is characterized in that stove is interrupted to produce, and furnace temperature changes in each heating cycle, as batch-type furnace, bogie furnace, shaft furnace etc.; Second class is a continuous furnace, is characterized in that stove produces continuously, divides temperature section in the burner hearth.
The big-and-middle-sized electric furnace that adopts with steel production in China enterprise is an example, though can energy savings and reduce pollution to atmosphere, but the noise that most of electric furnace produced is all more than 125 decibels, considerably beyond national relevant industrial enterprise noise sanitary standard, bring serious harm for site operation personnel's body and mind, surrounding environment has been caused the severe noise pollution.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can reduce the industrial furnace noise widely, protects operating personnel's physical and mental health effectively, reduces NOISE ON ENVIRONMENT to greatest extent and produces the electric furnace acoustic hood ventilation silencer that pollutes.
The purpose of this utility model is achieved by following technical proposals: comprise silencer element, noise elimination passage, housing, described housing is made up of shell, gusset and flange, described silencer element is made up of skeleton and deadener, it is characterized in that: at least one noise elimination passage is set in the described housing inner chamber, fills the abatvoix encapsulation of using the employing glass fabric to make behind the deadener in the skeleton of described silencer element.
Described noise elimination passage is broken line or wavy shaped configuration.
Described deadener adopts the deadener of different unit weights to make.
Compared with prior art, the utlity model has following advantage: simple and reasonable, can reduce noise significantly.Use when being suitable for industrial furnace room noise reduction.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram;
Fig. 2 partly cuts open the rotation enlarged drawing for the A-A of Fig. 1;
Among the figure: 1-abatvoix, 2-deadener, 3-silencer element, 4-shell, 5-gusset, 6-housing, 7-flange.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to accompanying drawing, the utility model comprises silencer element 1, noise elimination passage 3, housing 6, described housing 6 is made up of shell 4, gusset 5 and flange 7, described silencer element 1 is made up of skeleton and deadener 2, it is characterized in that: in described housing 6 inner chambers at least one noise elimination passage 3 is set, fills the abatvoix encapsulation that deadener 2 backs make of the employing glass fabric in the skeleton of described silencer element 1.
Described noise elimination passage 3 is broken line or wavy shaped configuration.In the direction that changes sound transmission, silencer element 1 can reduce noise effectively.
Described deadener 2 adopts the deadener of different unit weights to make.
During design, determine the appearance and size of electric furnace acoustic hood ventilation silencer according to the required ventilation of electric furnace acoustic hood, when electric furnace acoustic hood ventilation is big, design adopts many silencers to make up, the flow area of silencer is determined according to the wind speed of silencer during design, the wind speed of control silencer is less than 10m/s during design, thereby can determine the draught area of silencer.
Embodiment:
Housing 6 and silencer element 1 are separately made.
In the present embodiment, silencer element 1 is a broken line shape, earlier the skeleton of each silencer element 1 is welded, and fills the deadener 2 of different unit weights more on request, and the abatvoix of making of glass fabric is sealed and formed an integral body then.
When making suppressor case 6, assemble shell 4 earlier, again flange 7 and gusset 5 are welded on integral body of formation on the shell 4.
At last housing 6 and the 1 assembling welding of a plurality of silencer element are constituted a plurality of noise elimination passages 3.In the present embodiment, noise elimination passage 3 is 4 groups.
Electric furnace acoustic hood ventilation silencer of the present utility model is that special characteristics at the electric furnace noise design, existing good noise elimination effect, and the while also can be satisfied the ventilation effect of electric furnace acoustic hood.
