Abstract
A baking furnace for a resin sand regeneration casting, comprises a furnace body (1), a burner (2) and a drop material installation(3), in which an air chamber(5) is provided under a furnace bed(4) in the furnace body(1), a plurality of vents(6) are in connection with the air chamber(5) on the surface of the furnace bed(4), and the air chamber (5) is connected with a blower (8) through a heat exchanging pipe(7) that arranged in the furnace hearth. The baking furnace with this structure is of high heat efficiency, less energy consumption, evenly roasting and good effect of regeneration.
Description
Technical field the utility model relates to a kind of roaster that foundry resin sand regeneration power is handled that is used for.
After the background technology casting resin sand uses, still residual large amount of organic in the sand, directly Recycling.For removing the organic matter in the old resin sand, make the regenerating used reuse, adopt state to cross many processing methods both at home and abroad, but all be difficult in actual production, use because of processing cost height, weak effect.Owing to lack feasible recovery and treatment method, most of manufacturers have to topple over used resin sand when rubbish, cause the wasting of resources and environmental pollution.
The summary of the invention the purpose of this utility model provides a kind of roaster that recycles resin sand, and this roaster not only consumes energy less, processing cost is low, and treatment effect is good.
For achieving the above object, roaster of the present utility model comprises body of heater, burner and doffer, and body of heater is provided with siege, discharging opening and smokejack; One air compartment is arranged at the siege bottom, and the siege surface has the venthole that many air compartments therewith communicate; Air compartment places the heat exchange pipeline in the burner hearth to be connected with air blast by one.
As further improvement of the utility model, the blanking channel of doffer is in the burner hearth, and upper and lower opening communicates with burner hearth, at interval, be provided with transverse baffle alternately, forms the passage of " Z " shape on the sidewall of blanking channel.Knockout has the waste gas institute preheating of rising in burned back of long period in dropping process like this.
As further improvement of the utility model, the furnace wall is stretched out a tortuous cover plate downwards above the end in the discharging opening burner hearth, and the lower edge of this cover plate is roughly concordant with the discharging opening bottom.Combustion gas in the burner hearth can directly not run out of from discharging opening like this, reduces the loss of heat.
After adopting such structure, air blast is sent into the air compartment of siege bottom to air, and makes the old resin sand boiling (or springing up) that drops on the siege from the venthole ejection, thereby makes old resin sand obtain roasting fully, equably, and the regeneration treatment effect is good; And before entering air compartment, air is by the heat exchange pipeline in the burner hearth, and the waste gas residual heat that rises in burned back is heated into hot-air, and hot-air plays the effect of preheating again to old resin sand, improved the thermal efficiency of roaster so greatly, plays energy-conserving action.
The utility model is described in further detail below in conjunction with accompanying drawing for description of drawings.
Fig. 1 is the cutaway view of the utility model roaster structure.
The embodiment roaster that is used for the foundry resin sand regeneration power processing shown in Figure 1 comprises body of heater 1, burner 2 and doffer 3, and body of heater 1 is provided with siege 4, discharging opening 11 and smokejack 13.Siege 4 is positioned at the bottom of burner hearth, old resin sand on siege 4 by roasting.One air compartment 5 is arranged at siege 4 bottoms, has many ventholes 6 that communicate with air compartment 5 on siege 4 surfaces, and air compartment 5 is connected with air blast 8 by placing the heat exchange pipeline 7 in the burner hearth.Heat exchange pipeline 7 is on the top of burner hearth, waste gas after burning rises and produces heat exchange with the air that passes through heat exchange pipeline 7 when discharging, the air of air blast 8 supply air compartments 5 is heated to form hot-air like this, hot-air is from venthole 6 ejections, make the old resin sand boiling on the siege 4, simultaneously hot-air plays the effect of heating to old resin sand, the old resin sand of fluidized state easier by from the combustion gas of burner 2 ejections fully, evenly roasting, remove the organic matter in the sand effectively.The blanking channel 9 of doffer 3 is in the burner hearth internal upper part, and upper and lower opening communicates with burner hearth, and the waste gas that rises in burning back runs through blanking channel, when old resin sand when blanking channel falls by heating by the exhaust gases; On the sidewall of blanking channel, at interval, be provided with transverse baffle 10 alternately, form the passage of " Z " shape, can prolong the preheating time of knockout.The furnace wall is stretched out a tortuous cover plate 12 downwards above the end in discharging opening 11 burner hearths, and the lower edge of this cover plate 12 is roughly concordant with discharging opening 11 bottoms.Because the horizontal plane that drops on the old resin sand on the siege 4 is higher than the bottom of discharging opening 11 all the time, the lower edge of cover plate 12 is just inserted and is formed sealing in the sand, prevents that combustion gas from directly running out of from discharging opening 11.
