Description
1, technical field
The utility model relates to a kind of microwave technology, specifically a kind of plug-in type microwave soil sterilization bug killing equipment.
2, technical background
Along with the high speed development of modernization agricultural, the development of green food vegetable is more and more paid attention in people's life.Because natural world and soil are subjected to pollution in various degree.The germ insect pest that causes vegetables to produce is on the rise.Particularly in recent years, the root knot nematode disease of the melon dish generation whole nation and constantly propagation all over the world.Cause a large amount of green house of vegetables underproduction total crop failures.Causing many vegetable growers to increase agricultural chemicals measures and prevents and treats.Make the residual overproof of agricultural chemicals in the vegetables.Show that according to data most pathogens and insect pest mostly are deposited in the middle of the soil, treat that the evil feelings just take place when suitable environmental condition.Wanting to effect a radical cure harmful feelings handles soil and seems and be even more important.By specificity analysis to pathogen, insect pest, soil, adopt the advanced microwave friction heating effect that penetrates soil, sterilization, sterilization that principle possessed to soil carry out sterilization, good effect has been received in deinsectization.
From the mechanism of the principle of heating using microwave, microwave disinfection deinsectization and microwave three aspects of penetration capacity of soil are illustrated the feasibility of microwave to the soil sterilization deinsectization below.
(1) principle of heating using microwave:
Soil itself contains a large amount of moisture content, and central various bacteriums, worm's ovum, adult etc. can both absorb microwave energy in a large number, all are called as the medium of microwave.Dielectric material all is by polar molecule and nonpolarity molecular, is not having under the effect of electric field, and the center of nonpolarity intramolecule positive and negative charge overlaps, and has the center of the inner positive and negative charge of polar molecule not overlap.These polar molecules turn to state according to the polarity oriented of electric field from original distribution under electromagnetic field effect.And under the high-frequency electromagnetic field action, when medium was applied frequency and reaches the microwave electric field of 2450MHZ, direction of an electric field alternation each second 24.5 hundred million times, polar molecule were also swung 24.5 hundred million times thereupon.These orientations constantly change by frequencies of alternating electromagnetism, thereby this process has caused the motion of molecule to produce heat with mutual friction mutually.This moment, the field energy of alternating electric field was converted into the interior heat energy of medium, and medium temperature is constantly raise, and formed the heating using microwave of macroscopic view.Electromagnetic wave is to propagate with the speed of light, and the speed that electromagnetic wave penetrates material also is that the spread speed with light is close; And the time that electromagnetic energy changes the material molecule energy into is approximately instant, microwave frequency band conversion time was faster than ten million/one second.Here it is, and microwave can constitute the inside and outside principle of Fast Heating simultaneously.
(2) mechanism of microwave disinfection deinsectization:
The mechanism of microwave disinfection deinsectization is that bacterium, worm's ovum, adult are the same with any biological cell, is a kind of condensed state medium that is made of complex compounds such as water, protein, nucleic acid, carbohydrate, fat and inorganic matters.Wherein water is the main component of biological cell, content is at 75-85%, because the various physiological activities of bacterium all must have water to participate in just carrying out, and the growth and breeding process of bacterium is that diffusion, infiltration and suction-operated by cellulose finished to various nutraceutical absorptions.Insects under the effect of certain intensity microwave field in the soil and thalline also can absorb microwave energy and heat up simultaneously because of the molecular polarization relaxation.Because they are condensed state matters, intermolecular active force has aggravated microwave energy and has transformed to the energy state of heat energy.Thereby make the body internal protein be subjected to the effect that nonpolarity warm-up movement and polarity are rotated two aspects simultaneously, its space structure is changed or destroy, and make protein denaturation.After the protein denaturation, obvious variation all can take place in its solvability, viscosity, expansibility, permeability, stability, thereby loses biologically active; On the other hand, the non-thermal effect of microwave energy has played the unexistent special role of conventional physical sterilization in Pesticidal and sterilizing.
(3) microwave is to the penetration capacity of soil:
Penetration capacity is exactly the ability that electromagnetic wave penetrates into medium inside.When electromagnetic wave entered from the surface of medium and portion propagates within it, because energy constantly is absorbed and is converted into heat energy, its entrained energy was decayed with exponential form just along with the distance of going deep into dielectric surface.Transmission depth depends on moisture content, the looseness of soil, the transmitting power and the density of microwave.When microwave frequency was taken at 915MHZ and 2450MHZ, microwave was deep inner heating, showed to heat synchronously in during the heating using microwave certain depth being.The soil treatment that is used for green house of vegetables ground can meet the demands.Can be used for the farmland desinsection simultaneously, eliminate weed seed.Microwave equipment is installed to movably on instrument or the vehicle.Appropriate time carries out the terrestrial microwave irradiation in the land for growing field crops prior to seeding, and behind certain energy microwave irradiation, soil miospore, worm's ovum and weeds all are killed.Experimental results show that with after the microwave treatment sustainable 1 year of the effect of weeding, sterilization and desinsection.
3, summary of the invention
The purpose of this utility model provides a kind of plug-in type microwave soil sterilization bug killing equipment of reasonable in design, easy to use, one-object-many-purposes.
The purpose of this utility model realizes in the following manner; principle with heating using microwave; the mechanism of microwave disinfection deinsectization and microwave to the penetration capacity of soil as realizing theoretical foundation of the present utility model; and utilize power generation circuit the interchange low-voltage of 220V or 380V to be transformed into the dc high voltage of 2000V-4000V; dc high voltage makes microwave magnetron produce microwave energy; microwave energy enters into through waveguide in the media such as soil and realizes sterilization; the purpose of deinsectization; in order to strengthen the safety in the actual mechanical process, between power generation circuit and control circuit, also be connected to the magnetron thermal-shutdown circuit.
