Description

The sterilization method of seed and device

The present invention is a kind of sterilization method of seed, and the seed free-falling is contacted with disinfectant, by a rotating disk seed is thrown in the disinfection room in the outside again.And the device of implementing this method, this device has the disinfection room of a band seed batching and feeder, disinfectant that is thrown away by distributor gear in disinfection room and free-falling seed flow on the rotating disk that is positioned at below the dispensing disinfectant mechanism together, and are thrown away by the rotating disk break-in.

Introduced a kind of chlorination equipment that has disinfection room in Germany patent specification 531382, disinfectant beam wherein gets rid of wheel by one and is radially producing and be plane sprinkling.Getting rid of on the outside whole periphery of wheel, continuous falling vaporific seed, seed and disinfectant beam meet along a toroid then.This structure can not always make into satisfied fully, because on the wall of a part of disinfectant fractional precipitation auto levelizer, so can not reach sealing fully of seed.

Then has the opposite function of part therewith from the prior art in the Hungarian patent specification 157922.The particle that product is freely fallen a taper gets rid of on the dish, gets rid of dish and is installed in the disinfection room.Free-falling grain flow is on its whole whereabouts distance, by two nozzles of settling relatively.Particle gets rid of the direction of motion that dish can change grain flow, and can increase the time that each particle stops in disinfection room, so just can improve mixing between seed and the disinfectant.But these the two kinds solutions that come from prior art all have shortcoming, promptly disinfectant is directed onto above the device wall on opposite greatly, this no mercury disinfectant for frequent use is very unfavorable, because some such disinfectant thickness very can form incrustation on device wall.In addition, known device can not make disinfectant reach desired degree in the distribution of the surface of the seed, and what this can be very fast determines from seed sample.And the particle and the diffusion strength between the particle of seed also have very big difference.Up to the present, when adopting mercurous disinfectant, problem is also not too big, because can both reach uniform coating at all seeds of evaporation stage, even also can reach in the pocket to user's dress.Because evaporating pressure by mercury; the material of gas form is easy to be diffused into the hollow position on the surface of the seed; for example be diffused in the groove mark of particle, even in the tiny cavity therefore in the particle surface groove mark, also can be covered with protective layer to a certain extent.But some new tendency merits attention in recent years.A kind of tendency is, disinfectant can produce a kind of so-called Halo effect in soil, that is to say, is dissolved in the soil in the seed that some disinfectant can be sowed certainly, and peripherad soil diffusion, so that kill some detrimental microorganisms and mushroom in the soil within the specific limits.At this moment just not necessarily require disinfectant fully to be coated on the seed outside equably again.But, consider from ecological aspect in recent years, preferably do not handle seed by this approach.

Toxic because of mercury, so some country bans use of mercury as disinfectant, thereby make people be obliged to go to go to seek new solution, so that reduce toxic amount as far as possible from chemistry and structure two aspects.

Task of the present invention is, develops a kind of seed disinfection method, and the disinfectant consumption of this method is very little, but Disinfection Effect is good.In addition, also to develop the device that is applicable to this method.

Solution of the present invention is, in the method for mentioned kind, makes on the vaporific ringwise rotating disk that freely falls to basin shape of seed; Seed passes the flat-shaped disinfectant beam that outwards sprays in the annular mist in the process of free-falling; The seed that soaks into contact with disinfectant in being thrown out of the process of rotating disk once more, at this moment owing to seed grain continuous rolling and friction on rotating disk, causes disinfectant to be evenly distributed on particle surface and infiltrates in the particle.

Method of the present invention has good Disinfection Effect, because when the seed that falls of tentiform passes the disinfectant beam of plane annular ringwise, can produce relatively large infiltration surface, makes disinfectant extremely be evenly distributed in the surface of the seed.The seed of these infiltrations is fallen then on the basin shape rotating disk and from radial outward and is thrown away, because the position of seed on rotating disk constantly changes, makes that the disinfectant on every the surface of the seed distributes more evenly.In the process that is thrown out of, the seed of infiltration is sprayed again goes up disinfectant (for the second time).Like this, after the first time, impregnation process took place by a period of time, impregnation process has for the second time been arranged again.Impregnation process occurs in the process of seed annular curtain whereabouts for the first time.When for the second time impregnation process took place, impregnation process not only was through with for the first time, and because the disinfectant that the surface of the seed was stained with in the impregnation process in the first time, through rolling and throw away, and was further disperseed and homogenize on rotating disk.At this moment, then carry out the impregnation process second time again, more favourable to the even distribution of the surface of the seed disinfectant.Because the process and the secondary impregnation process that throw away on the seed autorotation disk take place simultaneously, can scatter equably so newly adhere to the disinfectant of the surface of the seed.Like this, when seed left rotating disk at last, the distribution of disinfectant was gone up very well with even in its surface.

It is found that the present invention can reach three kinds of effects, that is:

1) to spraying the first time of annular seed curtain;

2) to through the pre-seed that soaks in basin shape rotating disk, carry out the processing of rotary drum, mix and friction.

3) on rotating disk, seed is soaked into once more.

These three kinds of effects have produced beat all good result.There are a lot of examples to prove.By a higher relatively speed, seed is rotated around all possible axis, and towards various direction in space motion.This violent the rotatablely moving of seed, can impel the disinfectant drop that sprays to be planar shaped promptly scatter, even disinfectant is deep in the groove mark and cavity on the surface of the seed, and some cavity has only a tiny hole, just as a kind of oil, can accomplish to distribute very uniformly with very strong infiltration capacity.By strenuous exercise and the strong collision between the seed and the friction of seed, make seed mutual too much or very few disinfectant on the exchange surface in basin shape rotating disk, on the surface of seed a kind of process of rubbing of rubbing also can appear like this.

The present invention also allows other scheme with advantage:

A kind of scheme preferably is, the disinfectant beam of planar shaped is with the form ejection of atomization disinfection agent, and its atomizing is to get rid of dish and strong air-flow generation by one around the vertical axis high speed rotating.Tentiform falls with respect to being so just to make disinfectant, and the seed in the motion produces good guiding and break-in effect, also can improve the self-cleaning property of device simultaneously.

Device of the present invention is a kind of device of type as mentioned above, it is characterized in that, the outer rim of rotating disk is basin shape and upwards digs; Disinfectant spray body is installed in the rotating disk with one heart, and there is the seed batching spraying mechanism and rotating disk top and disperses passage, and seed passes passage and drops on the rotating disk with the form of annular mist.

Adopt device of the present invention, every seed is soaked into very up hill and dale.Compare with existing device, the consumption of the disinfectant of this device significantly reduces, and seed germination rate is unaffected, and does not damage seed or cause the seed fragmentation.

A kind of scheme preferably of device of the present invention is, rotating disk and disinfectant spray device have similar shapes (for example circular), and its central region plane preferably.

Another extraordinary scheme is, is the disk edge and the horizontal line oblique of basin shape, and its angle of cut preferably is not more than 75 °, and is proper between 30 ° to 75 °.This angle of cut should be chosen between 55 ° to 65 ° especially, preferably less than 60 °.On device of the present invention, it also is favourable that the seed guiding mechanism is installed in basin shape rotating disk top.By this guiding mechanism, can adjust the whereabouts track that is the seed that tentiform falls, seed is fallen in the presumptive area of rotating disk, particularly fall on the rotating disk central region to the transitional region between the outer ledge.

A kind of structure of implementing preferably of this scheme is that guiding mechanism has a seed with how much concentric installations of rotation of rotating disk and distributes awl, below seed arrives by the distribution coning tower tray.In addition, below the distribution of guiding mechanism awl and radial outside, the guide wall that a cylindrical shape is installed is also more favourable, and this guide wall preferably parallels with inwall.

Disinfectant spray device preferably is installed in the side that guiding mechanism is discharged seed, particularly is installed in to distribute the space that forms between poppet surface and the spigot surface, and it is adjustable preferably will to distribute awl to make.Like this, for example just can will distribute the guiding mechanism that awl and a cover can remote controls to link together.Distribute awl preferably to link together by a hollow circular-tube and a guiding mechanism that the disinfectant input unit is housed.

If disinfectant spray body is used as high rotating speed air motor simultaneously, then very favorable resultant effect can occur.The number of moving part of motor rotor is preferably in the scope of per minute 5,000 to 20,000 commentaries on classics, and the discharge air of motor can be used to the atomization disinfection agent.

The another kind of favourable structure of device of the present invention is, getting rid of of disinfectant spray body has a nozzle at least on the dish, its structure wants to guarantee that (ejection for the second time) disinfectant beam is not the zone line that is sprayed onto rotating disk, but is sprayed onto the place that becomes certain distance with zone line.Therefore, get rid of on half the height of the sidewall of upwards digging that dish preferably is installed in basin shape rotating disk, getting rid of dish will have one at least near the plane of level, and concentric with rotating disk.

In order to make whole device safety operation, and can reach good effect, the most handy air motor drives and gets rid of dish, and the jet exhaust of air motor can be used as the nozzle of disinfectant, so that produce jeting effect.In addition, the revolution of adjusting rotating disk with a mechanism also is favourable.A pump that can send disinfectant beam preferably is installed on the rotor of disinfectant spray body, a radial pump (what get rid of dish type is best) particularly is housed.The rotor of this radial pump has and the wheel rim blade of bevel radially.The air input channel that disinfectant spray body preferably has at least one atomizing to be connected with the disinfectant nozzle in addition.The zone of meeting at air and disinfectant should form a spray chamber.

The simple declaration of accompanying drawing:

Further the present invention will be described for the contrast accompanying drawing below, wherein:

Fig. 1 represents the longitudinal sectional drawing of a device embodiment of the present invention;

A local figure (enlarged drawing) of Fig. 2 presentation graphs 1;

The piping diagram of Fig. 3 presentation graphs 1 shown device;

Fig. 4 represents a kind of structure of the dispensing disinfectant mechanism of device of the present invention.

The detailed description of accompanying drawing:

The epimere of seed disinfection device 1 shown in Figure 1, it has a seed charging aperture 2, has batching gap 3 seeds to fall into process chamber 4 by batching gap 3 on the charging aperture.Can spray the disinfectant of ring plate shape in this chamber by disinfectant spray body 5, disinfectant spray body is connected with two flexible pipes.

Seed is added in the chlorination equipment 1 by charging aperture 2, and in the zone in batching gap, distributes awl 8 to spread out by one.Seed is tentiform and falls by after distributing awl.At this moment, each seed is a parabola in the tracks of distributing the awl bottom.This means that seed grain will fall on the relatively large face that is scattered on the rotating disk 9 that is installed in the disinfectant spray body bottom.In order to prevent that this phenomenon from taking place, assurance has a narrower face that is scattered, distributing awl 8 bottoms to connect one section cylindrical tube 11 that equates with its radius, a cylindrical guide wall 10 that radius is bigger has been installed again in the outside of this cylindrical tube, therefore seed is limited in a narrow annular extent, and Mu shape falls ringwise.

Feed gap 3 is being distributed between awl 8 and the hopper walls 13, and hopper walls is fixed by bolts on the shell of chlorination equipment 1 by external flanges dish 13, when being necessary, can unclamp bolt 14, unload the first half of lower device 1, so that change the funnel or the cylindrical tube of other gradient.This commutativity provides the possibility that coarse regulation is carried out in batching gap 3.The feed amount can also be adjusted by the height that regulates and distributes awl 8.Adopt remote control that adjustment is become and carry out easily, and can simplify adjustment work.Distribute awl 8 above the pipe 15 of ining succession, guiding mechanism 16 is equipped with in the upper end of pipe.

Guiding mechanism 16 is tracking control systems, and it has a connecting rod 17 that is connected with pipe 15 upper ends, and what the upper end of this connecting rod connected is diaphragm 18.At diaphragm 18 and be fixed on have one between the sleeve 19 on the shell and play return actuating pressure spring 20(return spring and can for example use air cushion spring or the like with other suitable flexible member replacement).Be a compressed air cell 21 above the contacted diaphragm 18 of spring, this chamber links to each other by air inlet 22 and compressed air source (do not draw among the figure, but can find on the schematic diagram of Fig. 3).With on the air inlet pipe 23 that air inlet 22 links to each other stop valve 24 is housed, this valve is installed on the base plate 26, and can be by lever 25 actions.Slide block 27 is arranged above the base plate 26, slide block can be adjusted upward by adjusting knob 28 and screw rod 29.A motor cover 30 is housed in the upper end of screw rod, can carries out remote control to the rotation of screw rod by motor.

Action lever 25 withstands on the control projection 31.Control projection and pipe 15 connect together, and as the detecting element of pipe diverse location.As long as, the free end of action lever 25 is withstood on the column part of projection 31 always by adjusting knob 28 or remote control 30, just valve 24 can be opened, base plate 26 is descended.At this moment the pressure in the compressed air cell 21 increase, and diaphragm 18 is moved down, and withstand on again on the inclined-plane of projection 31 until the free end of lever 25, thereby valve 24 is ended.When the inclined-plane that the structure of valve 24 can make lever 25 cross projection 31 arrived the extreme higher position, air inlet 22 and air inlet pipe 23 were connected with atmosphere, thereby pressure chamber 21 is communicated with atmosphere.Pressure in the pressure chamber 21 disappear like this,, come back on shown in Figure 1 and relative position lever under the effect of return spring 20 up to projection 31.

A kind of possible structural table of disinfectant spray body is shown among Fig. 4 and Fig. 4 a, is described in detail below.Should be noted that flexible pipe 6 and 7(see that a) being used for input (may be different types of sometimes) is the disinfectant of solid-state, liquid state or gaseous state for Fig. 1 and Fig. 4, and link to each other with the top of chlorination equipment.The top of chlorination equipment links together with disinfectant storage tank (not drawing in the accompanying drawing) again.In addition, in distributing awl 8 and coupled logical pipe 15, also has a compressed-air hose 33.From then on the compressed air that drives air motor 33 imported in the flexible pipe.Be the cavity of a long hole shape in the pipe 15,

flexible pipe

6,7 and 33 promptly is installed in this cavity.Should be pointed out that this structure makes whole disinfectants importation,, distribute awl 8 and coupled cylindrical wall 11 and little catotropic end socket awl 34 protective covers that constituted to be closed all by pipe 15, can prevent on the seed with dust invade.As shown in the figure, the angle of the marginal portion 9a that upwards digs of the angle of end socket awl 34 and rotating disk 9 about equally.

Flexible pipe 6 links to each other with a nozzle head 35 with 7 lower end, and (see Fig. 4 and Fig. 4 a), nozzle head concentric type ground is around the motor drive shaft of air motor 32.The lower end of motor drive shaft fixing a rotating disk shape get rid of the dish 36.In illustrated structure, motor 32 and nozzle head 35 are fixed on

conical element

8,11 and 34.If necessary, also can be fixed on

part

32 and 35 on the shell on top of whole device, for example can fix by a bar that passes pipe 15.On the next door of

conical element

8,11 and 34 inner flexible tubes 33, also have that an other logical compressed air uses 39, this flexible pipe connects together the rear end and the nozzle 35 of air motor 32.By this flexible pipe 39, just the gas that motor 32 can be discharged flow to nozzle head 35, from the gas of nozzle ejection because the effect of eddy current can improve the atomizing by

flexible pipe

6 and 7 disinfectants that flow into.So just can make disinfectant, particularly the liquid sterilant atomizing becomes very tiny drop, thereby disinfectant can well be spread out.

On process chamber 4 inner casing cover plates 41 motor 40 is installed, the bottom of this motor is worn-out open type, so that enter the cooling air.Casing cover plate 41 by parting bead 42 radially be fixed on process chamber shell 44 below.Axle 46 through holes 47 that pass on the installing plate 45 of motor 40, there is a block 48 end of axle.Block 48 constitutes releasable connection by a size on the rotating disk 9 similar centre bore and flange 49.For example just can change the geometrical relationship of structure according to seed by this connection, rotating disk 9 is pulled down, change and have the new rotating disk of other shapes, the rotating disk that for example has inclination angle, different edge and profile perhaps has the rotating disk of differing heights.Another possibility that adapts to the variety classes seed is, by cables that are contained in below the parting bead 42 motor and (unillustrated among a figure) revolution speed regulator are connected together, thus can adjust the centrifugal force relevant with revolution and and the edge tilt degree of rotating disk 9 centripetal force of being correlated with between size.

Contrast Fig. 2 is illustrated the action principle and the characteristics of pneumatic structure and aerodynamic force below:

Can have smooth zone line 9b around the rotating disk 9 of axis 52 rotations, knuckle 9c and the fringe region 9a that is inclined upwardly and digs.Fringe region 9a is less than 75 ° to horizontal oblique angle, particularly will be chosen in the scope between 30 ° to 75 °, is preferably between 55 ° to 65 °.In illustrated embodiment, this angle is 60 °.

Rotation by rotating disk 9 acts on centrifugal force size on the seed S, and mainly to drop on the rotating disk 9 which point relevant with seed.For this reason, cylindrical wall 10 and 11(are referring to Fig. 1) form a truncated annulus interval, so that the tracks of seed is limited in the direction shown in Fig. 2 upward arrow B.

Get rid of that dish 36 throws away to be generally liquid disinfectants be A along the horizontal plane 53(that dotted line is represented with the intersection point of disk edge at first) motion, but because inevitably beam expansion and earth attraction, this face will descend one section in illustrated shade scope.If seed S falls apart from the flat 9b of the closer rotating disk 9 of axis 52 and goes up (see figure 2), then want to intersect for the first time with the disinfectant beam that moves along line 53 earlier, and then fall on the rotating disk 9, subsequently because the effect of radial acceleration motion laterally again.(being in Fig. 2) to left movement.Seed enters in the shadow region of disinfectant beam in the process of outwards motion once more, and is sprayed again and go up disinfectant.Can make seed pass disinfectant beam twice by this process, thereby utilize beam very fully.

Among the embodiment shown in the figure, also utilized the additional effect of another one, this is called as " chop " in tennis tournament: the track B of seed S has passed through suitable design, seed S is fallen in the scope of knuckle 9c, and middle seed has just been fallen A ' point that fringe region begins upwards to dig.Level point A ' is positioned at apart from axis 52 relative places far away, and the centrifugal force that therefore acts on this place is also just relatively large.But, because the gradient of edge 9a, also exist one with this centrifugal force from anti-centripetal force.The result of the rotary interaction of these two power and rotating disk 9 causes turning to of track B not occur over just axially, and also occurs on the circumferencial direction of round turntable 9.The resultant effect of Chan Shenging is a spiral (the sweep B ' of comparison diagram 2 middle orbit B) therefrom.On this section of B ' track, each seed all will roll under the effect of radial pressure, and its rotating direction as shown by arrow D.Owing to also exist disinfectant beam 53 simultaneously, as shown in Figure 2, so this beam also towards same direction deflection, this just makes seed move along track B ' together with disinfectant.On this section of B ' track, every seed all can be in liquid disinfectant around the own axis D that rotates itself, and also disconnectedly on all faces be subjected to uniform infiltration again.Compare with the method for only processing being soaked in the side of seed S, this method can reach more strong effect of impregnation may.Employing is soaked into when handling the side of seed S, and the not saturated surface of seed might suffer that the moth of insect bites, thereby seed is ineffective.The geometrical relationship of mechanism is considered as a whole like this, make beamline 53 to one section of engagement point A by the track B of the seed S in the rotating disk 9 roughly half-and-half separately.Seed S roughly is positioned at the height that upwards dig in height h(disk edge zone having passed) after the disinfectant beam 53 at half place, the distance of passing by again L arrives engagement point A ', changes direction then again, along roughly same distance L to swivel motion, up to the point of contact of beamline 53 till.On online 53, the total radical length of orbital segment B ' is that L(is referring to the expression among Fig. 2).By the way, roughly half-and-half separated when passing beamline 53 again at the seed movement track B within the rotating disk 9, certainly wherein also exist certain error, this is can move up and down in the scope in boundary line 54 owing to getting rid of dish 36, sees the line of representing with chain-dotted line among Fig. 2 54.Can all break away from the disinfectant that also exists in the rotating disk 9 at O point seed, and be thrown out of rotating disk.As mentioned above, the accurate position that O is ordered is the revolution of rotating disk 9, and the quality of angle and every seed has substantial connection.

Contrast Fig. 3 was to once being illustrated to the control mechanism of introducing greatly in Fig. 1 below.Draw two control loops that are parallel to each other 62 and 63 from compressed air source 61.Control loop 62 is to be used for the height of Control Allocation awl 8 as mentioned above.63 controls that are used for air motor 32 of control loop.Allow for this purpose pipeline from compressed air source 61 in control loop 62 earlier by a pressure micro actuator V, by this micro actuator control loop 62 is remained under the predetermined constant pressure.The delivery outlet of micro actuator V is connected with the input port of the valve 24 that the top was mentioned, and the other end of valve 24 then connects together with pipeline 23.In addition, on valve 24, also has a blast pipe 64.According to the diverse location of action lever 25, pipeline 223 or with compressed air source 61(by reset valve V) link to each other, perhaps for pressure chamber 21 pressure releases are linked to each other with blast pipe 64.In addition, can also at any time pipeline 23 be closed by magnetic valve 25.

Also have a similar stop valve 66 to be installed in the control loop 63.In the loop, air motor 32 obtains compressed air by pipeline 33.Wherein can insert a lubricated mechanism 67 that is used to import motor 32.The gas that motor 32 is discharged is preferably failed back nozzle head 35 by pipeline 39, so that produce jet-action on the disinfectant that flows into.Nozzle head 35 and the details of getting rid of wheel 36 below it are seen shown in Figure 4:

Nozzle head 35 is fixed on air motor 32 on the nozzle head by screw 28 and is installed in above the installing plate 38 (referring to Fig. 1,4 and 4a), and is fixed by the mechanism of not drawing among the figure.Be connected with the branched pipe (arm 6a) and the flexible pipe 39 that are positioned at axis 52 both sides on nozzle head 35, arm 6a belongs to the branch on the disinfectant input flexible pipe 6, and flexible pipe 39 is used to import the gas that motor 32 is discharged.The about angle at 45 of the 6b of another branch of flexible pipe 6 and article one branched pipe 6a, this flexible pipe (see figure 4) that is connected with nozzle head 35; Can certainly connect second flexible pipe 7 again as shown in Fig. 4 a at this place, be used for importing other disinfectant.But flexible pipe 7 becomes 90 ° of angles of cut to stagger with the 6a of branch of flexible pipe 6 to be received on the nozzle head 35.No matter under which kind of situation, the syndeton of the flexible pipe 7 among branched pipe 6b or Fig. 4 a is identical with the syndeton of branched pipe 6a among Fig. 4.In this syndeton, flexible pipe is fixed on the nipple joint 70 on the nozzle mouth 35 by nut 69.Flow to the lower end of nozzle pipe with connecting hole 71 by hickey 70 from the disinfectant of flexible pipe 6 or 7.Connecting hole 71 is positioned on the doughnut 72, and the radially excircle of doughnut 72 is sealed by annular boss 73.Disinfectant passes doughnut 72 and is directed onto on the plane of getting rid of wheel 36 36a place, horizontal mesozone.In order to prevent splash (owing to do not note making drop to fall the outside of nozzle head 35, and in being deposited in the bottom of dress plate 38), a cover plate 36b has been installed on the 36a of mesozone; This piece cover plate becomes a determining deviation by following closely 74 slightly with the mesozone, can together rotate with the mesozone, also has a hole 75 simultaneously therebetween.Annular boss 73 on the nozzle head 35 stretches out from hole 75.Get rid of interaction energy by the throwing of getting rid of wheel 36 of high rotational speed the disinfectant that is between two dished plate 36a and the 36b is outwards moved, and throw away by the curve orientation blade 76 on the edge 36c that gets rid of dish 36.In order to make the disinfectant drop be easy to separate, the edge designs that will contain blade 76 becomes following shape, angle β between the plane of the outer surface extended line of edge 36c and horizontal mesozone 36a is an acute angle, its numerical value is preferably between 30 ° to 60 °, and is best about 45 ° greatly.

Also can import the disinfectant that is the form that atomizes by flexible pipe 6.In order to produce atomizing, need the thousands of high revolution of per minute, for example between per minute 5000 to 20000 changes.Therefore preferably use fluid motor, particularly adopt an air motor 32, the exhaust of this motor can also be used to the disinfectant atomizing by

flexible pipe

6 and 7 inputs.For reaching this purpose, exhaust hose 39 is connected on the hole 77 on the nozzle head 35 by hickey 70a.Hole 77 is connected with a cross-section passage 78 again, and cross-section passage is the hole that the excircle along nozzle head 35 gets out, and the opening of hole on external peripheral surface blocked by screw plug 70a.Intersect at an angle between hole 77 and the passage 78.

The end of passage 78 links to each other with doughnut 79, doughnut 78 in the zone that is connected with passage 78 around spools 80 of air motor 32.On opposite radially, passage 78 junctions, doughnut 79 is connected with an axial passage 81 that is parallel to axle 80, the liquid passage engaged with doughnut before the connector 71 between disinfectant input pipe and the doughnut 72, and, make air-flow mix mutually, atomize and spray from mouthful 71 outflow disinfectants from passage 81 ejections by this structure generation injection effect.

Cover plate 36b(sees Fig. 4) also have a subsidiary function.This piece cover plate and mesozone 36a formed together one from doughnut 72 radial passage to guide vane 36a.Because the suction that guide vane 76 high speed rotating are produced on doughnut 72 and conjugate foramen 71, this means that in fact the structure of getting rid of dish 36 among Fig. 4 or Fig. 4 a has formed the rotor of a radial pump by this channeling.This principle itself is irrelevant with the following fact; Utilize the disinfectant beam that is produced repeatedly or once to pass seed.In addition, can also produce disinfectant beam with the rotor of an axial pump when needed.36 be designed to radial pump-motor by getting rid of dish, lucky the combining between the radially beam that has produced a kind of torus shape and the above-mentioned swabbing action.Wherein also can replace the cover plate 36b that rotates with a fixed head, lead to guide vane 76 with formation, the structure of this piece fixed head can be the same with rotation cover 36b, but be not to be fixed on the mesozone 36, but be fixed on above the installing plate 8.

If do not adopt air motor, the injection equipment of said structure also has certain advantage.It is also irrelevant that wherein doughnut 72 mainly contains the shape of making the radial pump rotor that has guide vane 76 in whether.(certain rotor as pump can help the homogenising more of suction when existing.)

If rotating disk is made with pore-free material, for example do not use the sieve plate manufacturing, be very favourable then to this device.Although at this moment will throw away also harmless by centrifugal force from the wheel rim on wheel disc top whole seed material and all disinfectants.
