Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 1-4, the present invention relates to an electromagnetic open oven, which comprises an oven body 1. The feeding end of the oven body 1 is provided with a wind direction guide seat 2 for guiding the circulating gas entering the oven body 1. The discharge end of oven body 1 is equipped with along the inside U type induction port 3 that arranges of oven body 1 for retrieve the gas that has the heat in the oven body 1, with thermal direct loss in the reduction oven body 1. And a circulating fan 4 is arranged above the oven body 1 and used for providing power for the circulation of the gas in the oven body 1.

And a dust removal and dehumidification box 5 is arranged on one side of the circulating fan 4 and is used for removing dust and dehumidifying the gas entering the circulation in the oven body 1. One end of the dust removal and dehumidification box 5 is communicated with the U-shaped air suction port 3, the other end of the dust removal and dehumidification box 5 is communicated with the air suction end of the circulating fan 4, the air outlet end of the circulating fan 4 is communicated with the wind direction guide seat 2, and circulation of gas in the oven body 1 is realized.

And a wind-uniform pore plate 6 is arranged on one side of the wind direction guide seat 2, which is far away from the feeding end of the oven body 1. Specifically, a plurality of vent holes are uniformly formed on the air-homogenizing pore plate 6. When gas blows to the uniform air pore plate 6, part of air passes through the vent holes, and part of air is blocked by the uniform air pore plate 6 and flows into the oven body 1 from the periphery of the uniform air pore plate, so that the gas in the oven body 1 is more uniform respectively, and the uniformity of the temperature in the oven body 1 is improved. And one side of the U-shaped air suction port 3, which is far away from the discharging end of the oven body 1, is provided with an air guide assembly for guiding the air in the oven body 1 to enter the U-shaped air suction port 3.

In this embodiment, air storage cavity 7 has been seted up in wind direction guide holder 2, and air storage cavity 7 is linked together with circulating fan 4's air-out end, and the width of air storage cavity 7 is unanimous with the inside width of oven body 1. One side of the air storage cavity 7 is provided with a convex block 8, a flow limiting channel 9 communicated with the air storage cavity 7 is arranged above the convex block 8, and one side of the flow limiting channel 9 far away from the air storage cavity 7 is provided with an air outlet 10 which gradually increases. Wherein, the width of the flow-limiting channel 9 and the air outlet 10 is consistent with that of the air storage cavity 7.

When the gas blown out by the circulating fan 4 enters the gas storage cavity 7, the gas cannot directly enter the oven body 1 due to the flow limiting effect of the flow limiting channel 9, but the gas storage cavity 7 is filled with the gas, and then uniformly enters the oven body 1 from the flow limiting channel 9 and the air outlet 10. Therefore, the gas entering the oven body 1 is uniform, and the phenomenon that the gas is blown to one point only is avoided. The gradually increased air outlet 10 can effectively guide air to be blown to the interior of the oven body 1 more uniformly.

The dust removal and dehumidification box 5 is provided with a filter cavity 11 and a dehumidification cavity 12. A plurality of filter screens 13 are installed in the filter cavity 11, and a dehydrating agent is filled in the dehumidifying cavity 12, so that dedusting and dehumidifying of the circulating gas are realized.

The mesh number of the plurality of filter screens 13 is increased from one end of the filter cavity 11 far away from the dehumidification cavity 12 to the other end of the filter cavity. If three filter screens 13 are provided in this embodiment, if the mesh number of the filter screen 13 far from the dehumidification chamber 12 is 300 meshes, the mesh number of the second filter screen is 600 meshes, and the mesh number of the third filter screen is 1200 meshes. The dust in the circulating gas can be effectively removed by the filtering mode.

Preferably, the water removal agent is activated carbon or molecular sieve.

The air guide assembly comprises a stepping motor 14 and two air blocking doors 15. The two air blocking doors 15 are rotatably arranged in the oven body 1 through a rotating shaft 16, and the two air blocking doors 15 are symmetrically arranged; gears 17 are arranged on the two rotating shafts 16, and the two gears 17 are meshed. The stepping motor 14 is installed above the oven body 1, and one of the rotating shafts 16 penetrates through the oven body 1 and is connected with a driving end of the stepping motor 14. Through the arrangement, the stepping motor 14 can effectively drive the two air blocking doors 15 to open or close. When the worker needs to observe the inside of the oven body 1, the air blocking door 15 can be folded to facilitate observation; when observation is not required, the damper 15 is unfolded to be inclined with respect to the moving direction of the conveyor belt in the oven body 1, and the flowing gas is introduced into the U-shaped suction port 3.

The utility model discloses a theory of operation is: when the oven works, the interior of the oven is heated by the electromagnetic heating device. At this time, the circulation fan 4 is turned on. The circulating fan 4 sucks the gas with heat in the oven body 1 through the U-shaped air suction port 3, and sends the gas into the wind direction guide seat 2 after the gas is dedusted and dehumidified by the dedusting and dehumidifying box 5. The air is uniformly blown into the oven body 1 through the guiding effect of the air direction guiding seat 2 on the air. And the gas enters the U-shaped air suction port 3 again under the guiding action of the damper 15 after passing through the oven body 1, so that the gas in the oven body 1 is circulated. Because the gas in the oven body 1 can circulate, the gas loss in the oven body 1 can be effectively reduced.

The above is only the preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which will not affect the utility model and the utility of the patent.
