Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
It please refers to shown in Fig. 1-5, resin self-setting sand sand mold mold cavity surface drying oven comprising be covered on above sand mold type chamber
Bonnet 1 and the furnace body 2 that is connected on 1 upper surface of bonnet, the top of the furnace body 2 is provided with the feeding port for being put into furnace charge
3, the sidewall bottom of furnace body 2 is equipped with air inlet 4, the inner cavity of the furnace body 2 and horizontally disposed and be symmetrically arranged in furnace body two
The exhaust pipe 5 of side is connected, and the outer end of the exhaust pipe 5 is connected with the hot air pipe 6 being vertically arranged, under the hot air pipe 6
It holds and is connected with the hot-blast outlet 7 being opened on bonnet 1, the grate 8 of the furnace body 2 being internally provided with for holding up furnace charge,
The exhaust pipe 5 is connected with the junction of hot air pipe 6 with the gas outlet of pressure pipe 9, and the middle part of pressure pipe 9 is provided with and supplies
The pressure port 10 that the High Pressure Air Pipe Line of high pressure gas is connected.
The hot air pipe 6 includes hot wind diversion pipe 11 and the hot wind shield 12 for being set to 11 lower end of hot wind diversion pipe, described
Deflector 13 is provided in hot wind shield 12, hot wind shield 12 is cone-shaped structure, and heat release hole is distributed on the deflector 13
14, the two sides of deflector 13 are respectively symmetrically connected with a rotary shaft 15, and one of insertion of rotary shaft 15 is opened in hot wind shield
In rotating hole in cover 12, another rotary shaft 15 passes through the water conservancy diversion handle 16 rotated after hot wind shield 12 with control deflector 13 and connects
It connects, the deflector 13 is circular configuration, and the heat release hole 14 on 13 upper surface of deflector is inclined hole.
Bonnet 1 all covers type chamber, and makes to be formed between bonnet 1 and type chamber close to sealing cavity but still with the external world even
It is logical, the furnace charge of burning is filled up into furnace body 2 by feeding port 3, generates high-temperature hot air after full combustion, comes from high-pressure air tube
The pressure-air in road by pressure pipe 9 through 6 arrival type chamber of hot air pipe, by Bernoulli phenomenon it is found that hot-air is by exhaust pipe in furnace body 2
5, hot air pipe 6 is transported to the baking of type chamber realization type chamber.
Different baking-type chambers may be implemented by controlling water conservancy diversion handle 16 when hot-air flows to deflector 13 by hot air pipe 6
Mode: baking initial stage, cavity temperature is low, therefore hot-air demand is big, can control deflector 13 in 1. working condition, this shape
Maximum into the hot blast rate of type chamber under state, the heating of type chamber is most fast；Mid-term is toasted, in order to avoid hot-air is always towards the same position of type chamber
It sets and blows, can control deflector 13 in 2. or 3. working condition, so that hot-air is changed the direction for entering type chamber, it is different to reach type chamber
Position can receive hot-air；The later period is toasted, cavity temperature needs hot-air master already close to ignition temperature in furnace body at this time
If maintaining cavity temperature to reach close to temperature constant state, it can control deflector 13 in 4. working condition, enter under this state
The hot blast rate of type chamber is minimum, and hot-air uniformly scatters to type chamber by the scattering hole of deflector 13, with this realize type chamber uniformly,
Sufficiently drying.
