Novel tunnel formula industrial microwave apparatus

Technical field:

The utility model relates to a kind of microwave equipment, relates in particular to a kind of tunnel type industrial microwave apparatus.

Background technology:

Microwave equipment is a kind of modernized kitchen range with microwave heating of food or other article, and microwave is a kind of electromagnetic wave.This electromagnetic energy is not only much bigger than common radio wave, and microwave at a touch metal just reflects, and metal has no idea to absorb or conduct it at all; Microwave can pass insulating material such as glass, pottery, plastics, but can consumed energy; And contain food or other article of moisture, and microwave not only can not see through, and its energy can be absorbed on the contrary.Microwave is meant that wavelength is 0.01～1 meter a radio wave, and its corresponding frequency is that 30000 megahertzes are to 300 megahertzes.In order not disturb radar and other communication systems, the operating frequency multiselect of microwave equipment is with 915 megahertzes or 2450 megahertzes.

Shown in Figure of description 2: the tunnel type industrial microwave apparatus mainly comprises equipment body 200 and by heating chamber 201, a plurality of magnetrons 202, the microwave source that high-tension transformer 203 is formed, be provided with the heating chamber 201 that microwave energy is become heat energy and the object of needs heating is heated in the center of equipment body 200, being provided with microwave generating apparatus at the top of heating chamber 201 is magnetron 202, magnetron 202 needed high pressure and heater current are mainly provided by microwave high pressure transformer 203, microwave high pressure transformer 203 is arranged on the bottom platform of equipment body 200, and is connected with magnetron 202 by high-tension line 204; Shown in Figure of description 3, be another kind of and accompanying drawing 2 heteroid microwave equipments 300, this microwave equipment 300 is with its difference, magnetron 301 is arranged on the outer face of keeping away of heating chamber 302, and high-tension transformer 303 is arranged on the outside and microwave equipment 300 disengagings of entire equipment, is connected with magnetron 301 by high-tension line 304.When high-tension transformer 203 was magnetron 202 power supplies, magnetron 202 obtained can produce microwave energy behind high pressure and the heater current, and magnetron 202 is diodes that place the stationary magnetic field in fact.Electronics interacts with the electromagnetic field of high frequency under the control of orthogonal stationary magnetic field and steady electric field in the pipe, is transformed into microwave energy obtain energy from steady electric field, thereby reaches the purpose that produces microwave energy.

Two kinds of magnetron of the prior art 202 needed high pressure and heater current are all provided by microwave high pressure transformer 203, in the coupled process of high-tension transformer 203 owing to high-tension line 204 reasons produce line loss, make the electronics that reaches in magnetron 202 pipe can not be under the control of orthogonal stationary magnetic field and steady electric field, interact with high frequency magnetic field, caused like this energy to be transformed into microwave energy completely in the steady electric field, do not reach the purpose that magnetron 202 produces microwave energy, even it is also unstable comparatively speaking to have produced microwave energy, operating efficiency is extremely low.

The utility model content:

The purpose of this utility model is to be used for remedying the loss of prior art high-tension line to cause in the steady electric field energy can not be transformed into microwave energy and difficult in maintenance etc. not enough fully, and a kind of novel tunnel formula industrial microwave apparatus is provided.

To achieve these goals, the technical solution of the utility model is as follows:

Novel tunnel formula industrial microwave apparatus, this equipment mainly comprise equipment body, heating chamber, a plurality of magnetron and high-tension transformer, and this equipment also comprises filament transformer and electric capacity;

Described filament transformer is arranged on the heating chamber top, and joins with magnetron;

Described filament transformer is electrically connected with high-tension transformer by high-tension line;

Described electric capacity is arranged on the high-tension line that connects filament transformer and high-tension transformer;

Described high-tension transformer is installed in the equipment body or is installed on outside the equipment body.

This practical tunnel type industrial microwave apparatus new structure is simple, on the basis of original industrial microwave apparatus, improve, make the layout of entire equipment that greater flexibility arranged, main frame is more succinctly attractive in appearance, it is more convenient to safeguard, and directly provide heater current for magnetron by filament transformer, reduced the loss of high-tension line, make the energy that from steady electric field, obtains of magnetron be transformed into microwave energy, thereby reach the purpose that produces microwave energy, improved its operating efficiency and firing rate greatly.

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

With reference to shown in Figure 1:

A kind of novel tunnel formula industrial microwave apparatus, this microwave equipment mainly comprises equipment body 100 and by heating chamber 101, four magnetrons 102, the microwave source that high-tension transformer 103 is formed, be provided with the heating chamber 101 that microwave energy is become heat energy and the object of needs heating is heated in the center of equipment body 100, being provided with microwave generating apparatus at the top of heating chamber 101 is magnetron 102, side at magnetron 102 is provided with the filament transformer 105 that is used to control heater current, filament transformer 105 is connected with magnetron 102 by being electrically connected, magnetron 102 needed high pressure and heater current are mainly provided by microwave high pressure transformer 103, the high-tension line that connects filament transformer 105 and microwave high pressure transformer 103 is provided with electric capacity 106, so just realized that filament transformer 105 provides the effect of heater current separately for magnetron 102, the outside and equipment body that microwave high pressure transformer 103 is arranged on equipment body 100 break away from, and can realize that it moves freely.

When power supply provides about 4000V high pressure to magnetron, send it to filament transformer 105 through high-tension transformer 103, filament transformer 105 is regulated through transformation it is adjusted into suitable heater current, make it be sent to magnetron 102, magnetron 102 is under the excitation of heater current, obtain to produce microwave energy behind high pressure and the heater current, magnetron 102 is diodes that place the stationary magnetic field in fact, electronics in this diode is under the control of orthogonal stationary magnetic field and steady electric field, interact with the electromagnetic field of high frequency, be transformed into microwave energy from steady electric field, obtaining energy, thereby reach the purpose that produces microwave energy, the continuous microwave that produces, pass through Wave guide system again, be coupled in the heating chamber, near the import department of heating chamber, a rotatable stirrer is arranged, because blender is the metal of fan shape, the reflection that after rotation is got up microwave is had all directions, so can be evenly distributed in microwave energy in the heating chamber, the power bracket of microwave equipment is generally 500～1000 watts.

When microwave radiation is to article, always contain a certain amount of moisture in the article, and water is that the orientation of this polar molecule will change with microwave field by polar molecule (the positive and negative charge center of molecule is not even overlap when external electric field does not exist yet) composition.Because this motion of the polar molecule of water in the article.And the interaction between adjacent molecule, produced the phenomenon of similar friction, water temperature is raise, therefore, the temperature of article has also just risen.With the article of microwave heating, because of its inside also is heated simultaneously, whole object is heated evenly, programming rate is very fast.
