Abstract
The utility model discloses a soundproof door of a soundproof shield for an electric furnace , which comprises a door frame (1), door leaves (2), a handle (3) and a hinge (4), wherein sound eliminating material (6) is filled in the inner chambers of the door leaves (2); sound absorbing plates (5)are arranged on the four surfaces of the door leaves (2) matched with the door frame (1) and an inward surface of the door leaves (2); and the matching surfaces of the door leaves (2) and the door frame (1) use a slanting tongued-and-grooved sealing structure of which the inner is small and the outer is big. The sound absorbing plates (5) are made of glass fabric, and a group of through holes is arranged on the glass fabric. The sound eliminating material (6) 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 the noise prevention of the electric furnace.
Description
Technical field
The utility model relates to a kind of environment-friendly products, particularly relates to a kind of electric furnace acoustic hood soundproof door.
Background technology
Domestic and international big-and-middle-sized iron and steel enterprise all uses the electric furnace steel making of various model specifications, and this is because above-mentioned industrial furnace can energy savings, reduces the pollution to atmosphere.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.
At present, the big-and-middle-sized industrial furnace that steel production in China enterprise adopts, though can energy savings and reduce pollution to atmosphere, but the noise that most of industrial furnace produces 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, and a kind of electric furnace acoustic hood soundproof door that the door opening place noise of electric furnace acoustic hood can be reduced to below 85 decibels is provided.
The purpose of this utility model is achieved by following technical proposals: comprise doorframe, door leaf, handle and hinge, the inner chamber of described door leaf is filled deadener, and four faces and door leaf face inwardly that described door leaf cooperates with doorframe are provided with abatvoix on totally five faces; The mating surface of described doorframe and door leaf adopts inner small and outside big oblique groove and tognue type hermetically-sealed construction.
Described abatvoix adopts glass cloth to make, and one group of through hole that is used for sound-absorbing is set on the glass cloth.
Described deadener adopts the deadener mixing manufacture of different unit weights to form.
Compared with prior art, the utlity model has following advantage: simple and reasonable, can reduce noise significantly.Being suitable for the electric furnace noise control uses.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram;
Fig. 2 is the door leaf A-A cutaway view Amplified image of Fig. 1.
Among the figure: 1-doorframe, 2-door leaf, 3-handle, 4-hinge, 5-abatvoix, 6-deadener.
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 doorframe 1, door leaf 2, handle 3 and hinge 4, and the inner chamber of described door leaf 2 is filled deadener 6, and four faces and door leaf face inwardly that described door leaf 2 cooperates with doorframe 1 are provided with abatvoix 5 on totally five faces; Described doorframe 1 adopts inner small and outside big oblique groove and tognue type hermetically-sealed construction with the mating surface of door leaf 2.
Described abatvoix 5 adopts glass cloth to make, and one group of through hole that is used for sound-absorbing is set on the glass cloth.
Described deadener 6 adopts the deadener mixing manufacture of different unit weights to form.
Embodiment:
Outside the original acoustic hood of industrial furnace soundproof wall and soundproof door are set, described soundproof door is made up of doorframe 1, door leaf 2, handle 3 and hinge 4.The inner chamber of described door leaf 2 is filled deadener 6 deadener that the deadener of different unit weights mixes of serving as reasons, and four faces that door leaf 2 cooperates with doorframe 1 and door leaf face inwardly are provided with the abatvoix 5 of the perforated plate making of usefulness glass cloth on totally five faces; Described doorframe 1 adopts inner small and outside big oblique groove and tognue type hermetically-sealed construction with the mating surface of door leaf 2.
Described doorframe 1 adopts inner small and outside big oblique groove and tognue type hermetically-sealed construction with the mating surface of door leaf 2, with glass cloth make abatvoix 5, by the deadener 6 that the deadener of different unit weights mixes, their acting in conjunction can obtain better defening effect.
Adopt electric furnace acoustic hood soundproof door of the present utility model, can prevent effectively the electric furnace noise by soundproof door to external radiation.The oise insulation factor of soundproof door require for oise insulation factor＞45 decibel be just to guarantee the whole defening effect of electric furnace acoustic hood.
After using product of the present utility model, the door opening place noise of acoustic hood is reduced to below 80 decibels from 125 decibels, has obtained good defening effect.
