Abstract
The utility model discloses a well-type closed cell perlite gas flame expansion furnace. The external part of the expansion furnace is a furnace frame which is formed by a multilayered overlapped maintenance platform, and is combined with a steel shell; the inner side of the steel shell is provided with an insulating layer inside which a helix revolving flame-retardant coating is arranged; a furnace liner is arranged inside the helix revolving flame-retardant coating, and penetrates the tow ends of the vertical structure of the expansion furnace body; the top end of the furnace liner is abutted with a feeding system, and the lower end thereof is provided with a discharging and guiding mechanism; and an annular space baiting device is arranged between the furnace liner and the feeding system. The opening end of a flame-thrower nozzle extends to the inside of a heating chamber; and the flame thrown out revolves along a helix revolving slot from top to bottom, thereby forming a temperature gradient which gradually rises temperature from top to bottom. Therefore, the temperature of the heating chamber is uniform, and the heat availability utilization is improved, the problem that the furnace liner is easy to be melted is solved, and the cost is lowered.
Description
Technical field
The utility model belongs to and utilizes the gas flame heat radiation, particularly utilizes the flammable gas burner of coal gas generation output, nonmetal ore in sand form is cleaned the well type hole-closing perlite gas flame puffing furnace field of expanded deep processing.
Background technology
Expanded hole-closing self control pearl stone is widely used in various fields.In recent years domestic-developed is the closed perlite puffing furnace of the heat radiation " dying fire is expanded " of thermal source with the electric furnace heating wire, though solved pollution problem, because heating-up temperature is hanged down the problems such as output is restricted and rate of closed hole is low, less economical, energy utilization rate is low that exist.As follows specific to the problem of depositing in the production practices: 1, the furnace temperature of the hole-closing self control pearl stone puffing furnace of electric furnace heating wire heating is difficult to reach more than 1100 degree, otherwise stove silk fusing phenomenon very easily occurs.2, after the electric furnace heating wire fusing, must make the cooking stove cooling, then the high temperature resistant stainless steel pipe be sling, down to the burner hearth the inside, change or keep in repair by artificial.3, under charged situation, the electric furnace heating wire of fusing very easily with high temperature resistant stainless steel pipe collision, cause shorted to earth and puncture stainless steel tube.4, owing to electricity charge costliness, production cost is also very expensive.
The utility model content
The purpose of this utility model is to overcome the deficiency of depositing in the prior art, and providing a kind of is the pearl stone puffing furnace of heating source with imflammable gas flame, particularly the flammable gas burner of gas generator output.Heating-up temperature for furnace internal-lining is even, avoid fusing body of heater facility or structure.
The utility model has adopted following technical scheme for this reason: described well type hole-closing perlite gas flame puffing furnace, comprise furnace body frame, steel body of heater shell, spiral and rotary type flame retardant coating, furnace internal-lining and the discharge that is arranged on feeding system that the body of heater cover top portion docks with furnace internal-lining, furnace internal-lining structure bottom draw and send mechanism; The Outboard Sections of described well type hole-closing perlite gas flame puffing furnace is the furnace body frame that the overlapping inspection platform of multilayer constitutes, described furnace body frame combines with steel casing, the inboard of steel casing is provided with heat-insulation layer, the spiral and rotary type flame retardant coating is constructed in the inboard of heat-insulation layer, the installed inside furnace internal-lining of described spiral and rotary type flame retardant coating, furnace internal-lining connects the two ends of described puffing furnace body of heater vertical structure, the apical position of furnace internal-lining butt joint feeding system, and the lower end is provided with discharge and draws and send mechanism; Be provided with the annular space blanking device between described furnace internal-lining and the feeding system.
After adopting such structure, because the mouth end of flame-thrower nozzle extends in the heating chamber, the flame of ejection circles round from top to bottom along spiral turning slot, forms a thermograde that successively heats up from top to bottom.Therefore, improve the uniformity in fire box temperature and temperature field, improved heating efficiency, increased substantially the output and the quality of product; Solve furnace internal-lining fusing problem, and greatly reduced production cost.
