Abstract
The utility model relates to a tunnel type sintering furnace temperature area isolation device. The device comprises a heat insulation wall I and an air curtain II. A front face plate of the heat insulation wall and a back face plate of the heat insulation wall are respectively connected with the air curtain through a screw. The heat insulation wall is fixed between adjacent temperature areas inside a furnace cavity. The heat insulation wall is a hollow cavity which is formed by stainless steel plates in a welded mode, dry air is sealed in the cavity, and heat conduction of two side temperature areas of the heat insulation wall plate is cut off. The air curtain comprises an air curtain installing plate, an air curtain matrix, and a sealing ring. Compressed gas is guided to the air curtain. By means of special physical structure of the air curtain inner portion, a wind screen which is even and high in strength is formed so as to cut off heat exchange caused by cross-ventilation of the adjacent temperature areas. The heat insulation wall plays a role with the air curtain in decreasing interference of the heat conduction and the heat convection so as to guarantee independence of each temperature area and satisfy a demand of sintering process of sintered products. The tunnel type sintering furnace temperature area isolation device is simple and solid in structure, easy to maintain, free of any worn parts in the inner portion, and long in service life.
Description
Technical field
The utility model relates to a kind of tunneled sintering kiln warm area spacer assembly.
Background technology
The sintering process of sintered article has determined that the temperature of adjacent two warm areas has drop.Although, adopt radiation heating to have good directionality, because the existence of oven cavity atmosphere, some energy can lose because of convection action.Simultaneously, the trend of the oriented adjacent low-temperature space diffusion of the heat of high-temperature region, the actual temperature of adjacent low-temperature space is raised in this thermal diffusion meeting, affects sintering quality.At present also have some sintering furnaces to adopt gas blow pipe and directly form the thermal convection current that air curtain is blocked adjacent warm area, but compressed-air actuated like this consumption is large, cost is high; Also have the temperature zone partition apparatus of some practical external imports, although effect is pretty good, installation and maintenance are more complicated all.
The utility model content
The purpose of this utility model is for the problems referred to above, designs a kind of simple, practical tunneled sintering kiln warm area spacer assembly.Utilize the characteristic of air lower thermal conductivity, reduce the heat conduction of adjacent warm area; Utilize air amplification principle and wall attachment effect to form air curtain, block the thermal convection current between adjacent warm area.The apparatus structure simple rigid, interior without friction means, convenient for installation and maintenance, cost is low, environmentally safe.
For achieving the above object, design of the present utility model is: tunneled sintering kiln warm area spacer assembly of the present utility model links with the internal furnace wall by the link screw around the insulated wall, is fixed between the adjacent warm area of burner hearth; Insulated wall is welded into hollow cavity by corrosion resistant plate, with the dry air sealing wherein, utilizes the low heat conductivity of air, blocks the heat conduction of adjacent warm area.Injecting compressed air in the air curtain, air enters air curtain from compressed air inlet, blows afloat the gap by 0.05mm in the air curtain and blows out, and forms the air-flow thin slice of a high speed, because Koln reaches this air-flow thin slice drainage ambient air of effect, so that the intensity of air-flow, flow increase.Because the air curtain installing plate is close in the air blowing gap, because the wall attachment effect of air, the large flow gas of high strength forms even air curtain along the air curtain installing plate, blocks the thermal convection current between adjacent warm area.
According to above-mentioned utility model design, the utility model adopts following technical proposals:
A kind of tunneled sintering kiln warm area spacer assembly is comprised of insulated wall and air curtain, it is characterized in that described insulated wall is the hollow sealing cavity, and there is the guipure passage in central authorities.
Described insulated wall is the hollow cavity that is welded into by top board, biside plate, two panels, square frame, base plate, and central with the guipure passage, dry air is sealed in the cavity.
Described air curtain comprises air curtain matrix, air curtain installation version and sealing ring, air curtain matrix and air curtain are installed between the version and are passed through screw attachment behind the embedding sealing circle, the front of air curtain matrix has compressed air inlet to be communicated with air curtain matrix inner chamber, and this inner chamber is communicated with the gap of blowing afloat of bottom.
Described air curtain and insulated wall are connected by screw, and are installed between sintering furnace two warm areas.
The utility model has following apparent substantive distinguishing features and progress compared with prior art:
The utility model adopts insulated wall and the air curtain of hollow sealing cavity, can reduce thermal energy conduction and the thermal convection current of adjacent warm area, satisfies the sintering process demand, and is simple in structure firm, and maintenance easily, and is inner without wear-out part, long service life.
