Description
Technical field
The present utility model application belongs to Casting Equipment technical field, specifically discloses a kind of roasting furnace structure.
Background technique
When casting, the application of precoated sand need to consume a large amount of placer resource, so existing foundry enterprise can be to overlay film
Cast waste sand after sand molding carries out recycling and reusing.
Existing cast waste sand reuse method is main are as follows: thermal reclamation method and machine friction regeneration method.Wherein, hot
Method regeneration method is to launch cast waste sand into roaster, by high-temperature roasting, makes the organic matter and air on cast waste sand
In oxygen occur oxidation reaction, become gaseous oxygen compound, removed from cast waste sand surface.The sand grain surface of this method recycling
The organic matter of cleaning, surface attachment is removed totally substantially.
Existing roaster is mostly vertical, and in order to guarantee the treatment effect to cast waste sand, roaster height is higher,
Production, installation and production maintenance are more difficult, are extremely easy to happen and topple over.
Utility model content
The purpose of this utility model is to provide a kind of pair of cast waste sand treatment effect is good, and furnace body height is lower, just
In the roasting furnace structure of production, installation and production maintenance.
In order to achieve the above object, the base case of the utility model are as follows:
A kind of roasting furnace structure, the furnace body including the first sealing plate and equipped with top feed mouth, bottom discharge port, top into
It is ipsilateral that material mouth and bottom discharge port are in furnace body；First sealing plate is set in the middle part of furnace body, and furnace body is divided into upper roasting by the first sealing plate
Room and lower boiling-house；First sealing plate is equipped with the first air-guide part for being connected to upper firing chamber, lower boiling-house；On the side wall of upper firing chamber
It is provided with the first mistake material mouth, second is provided on the side wall of lower boiling-house and crosses material mouth, the first material mouth and top feed mouth excessively is in furnace body
Heteropleural, the second material mouth and bottom discharge port excessively are in furnace body heteropleural；The second air-guide part of downward boiling-house air inlet is equipped in furnace body.
The working principle and beneficial effect of this base case are:
Top feed mouth, bottom discharge port, the first sealing plate, the first air-guide part and second air-guide part etc. are set, firstly, first
Sealing plate is set in the middle part of furnace body, furnace body is divided into upper firing chamber and lower boiling-house, cast waste sand carries out high temperature roasting in upper firing chamber
Enter lower boiling-house after burning, the cast waste sand temperature after the lower indoor high-temperature roasting of boiling is higher.When roasting, cast waste sand is in furnace
Intracorporal flow trace (cast waste sand flows in furnace body similar to fluid) is class horizontally U-shaped, and cast waste sand specifically flows over
Journey are as follows: top feed mouth → first crosses material mouth → second and cross material mouth → bottom discharge port.In addition, need to be led by second when roasting
The downward boiling-house of gas part is passed through boiling wind, and the wind that boils is in the intracorporal motion profile of furnace are as follows: the second air-guide part → lower boiling-house → the
One air-guide part → upper firing chamber → top feed mouth.
When roasting, boiling wind (wind that boils at this time is cold air) is passed through by the downward boiling-house of the second air-guide part, makes lower boiling
Cast waste sand after rising indoor roasting is that (temperature useless in the indoor casting of lower boiling is a 300-400 DEG C of left side to the preheating of boiling wind
It is right).Then, the boiling wind of lower boiling-house is passed through in upper firing chamber by the first air-guide part, and one side high-boiling wind can be combustion-supporting,
It can be effectively reduced roasting energy consumption, on the other hand, boiling wind makes the indoor cast waste sand boiling of roasting, helps to ensure that casting
Antiquated sand roasts uniform.
In addition, due to cast waste sand enters in furnace body from top feed mouth (when entering from top feed mouth, cast waste sand temperature
Spend lower), boiling wind is discharged out of furnace body from top feed mouth, and upper firing chamber is used to roast cast waste sand, so from top
The boiling air temperature of portion's feed inlet discharge is higher, can effectively preheat to cast waste sand, can carry out to preheating effective
Utilization, further reduced roasting energy consumption.
Existing roaster be mostly it is vertical, cast waste sand flows in the vertical direction, and with boiling wind in adverse current, it is this
For vertical roasting stove because height is higher, production, installation and production maintenance cost are higher, are easy to topple over.With this vertical roasting
Furnace is compared, the application roaster be it is horizontal, make flow trace class horizontally U-shaped of the cast waste sand in this roaster, both guaranteed
The treatment effect of cast waste sand, and cost of manufacture can greatly be saved, and simple installation, substantially without maintenance.Market
On there is also some horizontal roasters with single-layer fluidized bed, compared with this roasting, the application has upper and lower two laminarization
Bed, keeps the roasting of cast waste sand more uniform, and in fluidized bed at elevated (lower boiling-house), cast waste sand is boiling wind preheating, upper fluidisation
In bed (upper firing chamber), boiling wind is combustion-supporting, and preheats to cast waste sand, further reduced roasting energy consumption.
In addition, this roaster directly roasts cast waste sand using gas flame, to the processing speed of cast waste sand
Fastly, high-efficient.
Further, gas flow area of the gas flow area of first air-guide part less than the second air-guide part.One side
Face, boiling wind can in lower boiling-house stay longer, ensure that boiling wind in the indoor pre-heat effect of lower boiling, it is another
Aspect can effectively ensure that boiling wind carries out the indoor flow strength of roasting, ensure that the indoor cast waste sand of roasting
What is roasted is more uniform.
Further, first air-guide part includes multiple the first vertical air hoses being applied on the first sealing plate, can be more
It is simple to be connected to upper firing chamber and lower boiling-house.
Further, first air-guide part further includes the first blast cap for being fastened on the first vertical air hose top, the first blast cap
Circumferential direction be provided with multiple first air ports, the setting of the first blast cap can effectively improve the intensity that boiling wind carries out firing chamber, make
The upper indoor cast waste sand boiling of roasting, guarantees cast waste sand and the boiling uniform heat exchange of wind.
Further, the lower part of the furnace body is equipped with the second sealing plate, and the top of the second sealing plate is lower boiling-house, the second sealing plate
Lower part is the air compartment being connected to extraneous gas source, and second air-guide part is set on the second sealing plate, and the second air-guide part includes second perpendicular
Straight air hose and the second blast cap for being fastened on the second vertical air hose top, the circumferential direction of the second blast cap are provided with multiple second air ports.Second
On sealing plate the second air-guide part setting can effective guarantee roasting after cast waste sand be boiling wind uniformly preheat.
It further, further include high-temperature steel plate, the inner sidewall of the furnace body is provided with buffering cavity, the side insertion of high-temperature steel plate
In the buffering cavity, the first sealing plate is fixed in furnace body by the high-temperature steel plate.High-temperature steel plate exists under the influence of temperature
Certain volume change when high-temperature steel plate is mounted in buffering cavity, there are certain surplus, can effectively ensure that roaster is run
When safety.
