Abstract
The invention discloses a sand core microwave drying kiln, which belongs to the field of cast and molded industrial furnaces. The microwave drying kiln is provided with a microwave drying chamber, wherein a waveguide pipe is arranged on the microwave drying chamber; bin gates are arranged on the front face and the back face of the microwave drying chamber; air suction holes are formed in the bin gates; and a conveying device is communicated with a feeding hole, a furnace kiln, the microwave drying chamber and a discharging hole sequentially. In the sand core microwave drying kiln, the microwave drying chamber is formed behind the furnace kiln; and due to the adoption of a microwave mode in combination with naked flame drying, the problems of non-uniform internal and external heating and uncompleted drying of sand cores are solved, drying time can be shortened, energy sources can be saved, and the drying kiln is environment-friendly and has high efficiency.
Description
Technical field
The present invention relates to a kind of core microwave drying kiln, it belongs to the industrial furnace field of casting.
Background technology
Core is the material that is used to make core in the Foundry Production, is generally added Modeling Material such as thing by casting model powder, moulding sand binder and auxilliary and mixes according to a certain percentage.Core is most of in casting mold to be surrounded by the liquid metal of high temperature, and the size of support localization part is generally less, so core sand also requires to have higher intensity, gas permeability, deformability and collapsibility except that the performance that should have general molding sand.Core sand is divided into clay core sand, waterglass core sand, wick sand, closes fat core sand, resin core sand etc. by used binding agent difference.
Mold drying oven is mainly used in sand mold or core is dry.Sand mold or core to casting usefulness heat, and make its contained humidity vaporization, evaporation to reach the industrial furnace of drying purpose.Organic matter in sand mold or the core, like wood chip etc., also in heating process by burning-off, thereby the gas permeability of sand mold is increased.Some bonding agents in the core like oils and pitch etc., just have cementability through heating, thereby the intensity of core is increased.
Baking temperature depends on the material composition of sand mold or core, and the baking temperature of core is 200～350 ℃.Mostly stove is flame furnace, and requiring has good air-flow cycling condition in the stove.The stove width should be established quirk in both sides during greater than 2 meters, and smokejack is established in the centre.The stove width can a side be established quirk during less than 2 meters, and opposite side is established smokejack.The core drying oven is generally made the chamber furnace thorax that has fire door.Sand mold or core are contained on the chassis, send into heat drying in the stove along track.It is different that the inside and outside degree of drying of core in use appears in this kind mode of heating easily, heats uneven situation, outer superheated occurs, and internal layer still has the situation of moisture.
Summary of the invention
Defective in view of prior art exists the object of the present invention is to provide a kind of core microwave drying kiln, and the inside and outside heating of solution core is uneven, dry halfway problem, and can shorten the dry time, can save the energy, environment-friendly high-efficiency again.
For realizing above-mentioned purpose, the technical scheme that the present invention adopted is: a kind of core microwave drying kiln comprises conveying device; Airduct and stove, stove one side is established quirk, and opposite side is established smokejack; There is conveyer the centre, between stove and the airduct, is provided with microwave dryer; Microwave dryer is provided with waveguide; The front and back of microwave dryer is provided with door and goes out door, goes out to have suction opeing on the door, and said conveying device is communicated with charging aperture successively; Stove, microwave dryer and discharging opening.Around the said microwave dryer and top is a sheet metal, and the door of microwave dryer is provided with the switching device of door opening electrical outage.The waveguide length at said microwave dryer top respectively is arranged in order.After the core process naked light drying, directly send into microwave dryer, after the microwave drying through airtight microwave dryer, deliver to discharging opening through conveyer.
After adopting such scheme; Compared with prior art has following beneficial effect: core microwave drying kiln; After stove, increased microwave dryer; Adopt the microwave form to cooperate naked light dry; It is uneven to solve the inside and outside heating of core, dry halfway problem, and can shorten the dry time; Can save the energy, environment-friendly high-efficiency again.

The specific embodiment
For understanding a kind of core microwave drying kiln in depth, illustrate as follows in conjunction with Fig. 1, Fig. 2:
A kind of core microwave drying kiln comprises conveying device 2, airduct 12 and stove 1; Stove 1 one sides are established quirk 3, and opposite side is established smokejack 5, and there is conveyer the centre; Between stove 1 and the discharging opening 11; Be provided with microwave dryer 9, microwave dryer 9 is provided with waveguide 7, and the front and back of microwave dryer 9 is provided with door 8 and goes out door 10; Go out and have suction opeing on the door; Said conveying device 2 is communicated with charging aperture 4 successively, stove 1, microwave dryer 9 and discharging opening 11.Around the said microwave dryer 9 and top is a sheet metal 6, and the door of microwave dryer 9 is provided with the switching device of door opening electrical outage.Waveguide 7 length at said microwave dryer 9 tops respectively are arranged in order.After the core process naked light drying, directly send into microwave dryer 9, after the microwave drying through airtight microwave dryer 9, deliver to discharging opening 11 through conveyer.Core microwave drying kiln has increased microwave dryer 9 after stove, adopt the microwave form to cooperate naked light dry, and the inside and outside heating of solution core is uneven, dry halfway problem, and can shorten the dry time, can save the energy, environment-friendly high-efficiency again.
