Abstract
The utility model discloses a high-temperature assistant soundproof plate of a soundproof shield for an electric furnace, which comprises a sound absorbing plate (1), an internal skeleton (2), a baffle (4), an external skeleton(5) and a panel (7), wherein the internal skeleton (2) and the external skeleton(5) are respectively welded on both sides of the baffle (4); the high-temperature assistant soundproof plate of a soundproof shield for an electric furnace is in a lapping structure on an assembly direction; ceramic fiber wool felts (3) are filled in a hollow chamber formed after the internal skeleton (2) is sealed by the sound absorbing plate (1); and mineral quits (6) are filled in a hollow chamber formed after the external skeleton(5) is sealed by the panel (7).The sound absorbing plate (1) is made of metal or non-metal plate material, and a group of through holes is arranged on the metal or non-metal plate material. The sealing structure of the sound absorbing plate (1) and the panel (7) is a welding structure, a riveting structure or a screw connecting structure. The utility model has simple and reasonable structure, and can obviously reduce noise. The soundproof door of a soundproof shield for an electric furnace 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 the high temperature resistant sound panel of a kind of electric furnace acoustic hood.
Background technology
The industrial furnace that mechanical industry is used has polytype, in casting department, the cupola furnace, induction furnace, resistance furnace, electric arc furnaces, vacuum drying oven, open hearth, crucible oven 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 property 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 hygienic 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; provide a kind of and can reduce the industrial furnace noise widely; protect operating personnel's physical and mental health effectively, reduce NOISE ON ENVIRONMENT to greatest extent and produce the high temperature resistant sound panel of electric furnace acoustic hood that pollutes.
The purpose of this utility model is achieved by following technical proposals: comprise abatvoix, inner frame, dividing plate, outer skeleton and panel, the high temperature resistant sound panel of described electric furnace acoustic hood is a tongue-and-groove structure in the assembly unit direction; The both sides of its dividing plate are welded inner frame and outer skeleton respectively, fill the ceramic fiber cotton blanket in the cavity of its inner frame with abatvoix encapsulation back formation; Fill the rock wool quilt in the cavity of described outer skeleton with panel encapsulation back formation.
Described abatvoix adopts metal or nonmetal plate to make, and one group of through hole that is used for sound-absorbing is set on the described sheet material.
The encapsulating structure of described abatvoix and panel is welded structure, staking structure or screw syndeton.
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 synoptic diagram;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;
Among the figure: 1-abatvoix, 2-inner frame, 3-ceramic fiber cotton blanket, 4-dividing plate, the outer skeleton of 5-, 6-rock wool quilt, 7-panel.
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 abatvoix 1, inner frame 2, dividing plate 4, outer skeleton 5 and panel 7, and the high temperature resistant sound panel of described electric furnace acoustic hood is a tongue-and-groove structure in the assembly unit direction; The both sides of described dividing plate 4 are welded inner frame 2 and outer skeleton 5 respectively, fill ceramic fiber cotton blanket 3 in the cavity that described inner frame 2 usefulness abatvoixs 1 encapsulation back forms; Fill rock wool by 6 in the cavity that described outer skeleton 5 usefulness panels 7 encapsulation backs form.
Described abatvoix 1 adopts metal or nonmetal plate to make, and one group of through hole that is used for sound-absorbing is set on the described sheet material.
The encapsulating structure of described abatvoix 1 and panel 7 is welded structure, staking structure or screw syndeton.
Tongue-and-groove structure is suitable for the assembly unit plate, and its structure is in the assembly unit direction, and a side of this assembly unit plate is positive head, an other side is cloudy tenon, its sun head falls in the cloudy tenon of second block of assembly unit plate, and its cloudy tenon entangles the positive head of the 3rd block of assembly unit plate again, and ad infinitum assembly unit is gone down in theory.
