Abstract
The invention discloses a heat-preservation sand bin of a used casting sand roasting furnace. The heat-preservation sand bin includes a shell body, a plurality of air ducts and a draft fan. The shell body is cylindrical in shape. A hot sand inlet is installed on the top of the shell body and a funnel-shaped sand outlet is installed on the bottom of the shell body. The air ducts are disposed in the shell body and are connected to each other successively from top to bottom, wherein the air duct at the most top is provided with an air outlet and the air duct at the most bottom is connected to the draft fan. By means of the sand bin, the majority of heat in hot sand can be recycled by hot air back to a furnace body of the roasting furnace, so that the heat can be recycled and energy saving and environment protection can be achieved.
Description
Technical field
The present invention relates to Casting Equipment manufacturing technology field, especially the insulation sand storage of casting old-sand regeneration roaster.
Background technology
The foundry goods annual production of current China reaches more than 2,400 ten thousand tons, and the overwhelming majority is wherein sand-cast, and the middle-size and small-size Foundry Works of more than 90%, mostly adopt clay-bonded sand and resin sand to produce.Due to technology backwardness relatively, a large amount of old sand often unprocessed direct input recycles, and causes all mass defect of foundry goods.
For solving the product quality problems brought thus, one of effective measures that can adopt are that old sand carries out regeneration use, and the ash content in removal old sand and the inertia coating film of sand grain surface, improve the processing performance of old sand, make it recover original characteristic.So just improve casting quality, the popularization of regenerating used technology and use are very necessary.
And if simple only sand is heated after cool again, make the heat angle that whole roasting process is wasted, be unfavorable for energy-conserving and environment-protective.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose the insulation sand storage of casting old-sand regeneration roaster, heat most of in hot sand can be sent back in roaster body of heater by hot blast by this sand storage, recycle heat be utilized, realizes energy-conserving and environment-protective.
In order to realize foregoing invention object, the invention provides following technical scheme:
The insulation sand storage of casting old-sand regeneration roaster, comprises housing, airduct and blower fan,
Described housing is cylinder, and top is provided with hot sand entrance, and bottom is provided with funnel-form sand export,
Described airduct has many be arranged on described enclosure interior and connect successively from top to bottom, and the described airduct being positioned at top is provided with air outlet, and the described airduct being positioned at lowermost end is connected with described blower fan.
Further, the some described airduct be arranged on the same cross section of described housing is horizontally uniformly distributed.
Further, described housing has double-deck refractory steel plates to be welded.
The insulation sand storage of casting old-sand regeneration roaster of the present invention, can be sent back to heat most of in hot sand in roaster body of heater by hot blast by this sand storage, recycle heat be utilized, realizes energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the insulation sand storage of casting old-sand regeneration roaster of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
The insulation sand storage of casting old-sand regeneration roaster as shown in Figure 1, comprises housing 5, airduct 2 and blower fan 4,
Described housing 5 is cylinder, and top is provided with hot sand entrance 1, and bottom is provided with funnel-form sand export 3,
Described airduct 2 has many be arranged on described housing 5 inside and connect successively from top to bottom, and the described airduct 2 being positioned at top is provided with air outlet 6, and the described airduct 2 being positioned at lowermost end is connected with described blower fan 4.
The some described airduct 2 be arranged on the same cross section of described housing 5 is horizontally uniformly distributed.
Described housing 5 has double-deck refractory steel plates to be welded.
During use, described air outlet 6 is connected with the air compartment air inlet of casting old-sand regeneration roaster body of heater, hot sand entrance 1 exports with the hot sand of casting old-sand regeneration roaster body of heater and is connected, hot sand falls from top and carries out heat exchange with cold wind in airduct 2 simultaneously, and heat exchange after heat sand falls into water cooling plant gradually by sand export 3.
The insulation sand storage of casting old-sand regeneration roaster of the present invention, can be sent back to heat most of in hot sand in roaster body of heater by hot blast by this sand storage, recycle heat be utilized, realizes energy-conserving and environment-protective.
