Fig. 3 is a kind of feeding device structure chart of simplification.

As shown in Figure 1, basic structure and traditional spray structure are similar, by storage tank 1, and big small cover, conduit 12, hand air pump device 9 is formed.The 8th, braces frame part, the 7th, valve.For satisfying multiduty equipped needs, the tank body top at storage tank is shown in outer neck and shoulder part, is provided with standby band valve and connects mouth 3, eck 2 in being provided with below its neck, capping.The reaction mass charging gear is set in the eck hole just constitutes antomobile sprayer.Specifically Zhuan Zhi outside is a reaction tube 11, reaction cartridge material (as agricultural carbon ammonium) in cylindrical shell top has passage, tube, with loading hopper 4, material storage tube 10, contain liquid material (as acid solution) in the material storage tube and be provided with improved drainage tube 13 therein, drainage tube 13 lower ends place the tube end of material storage tube 10, and the epimere of barrel is fixed and be opened in the upper end.This drainage tube helps making full use of the material storage tube volume.Liquid material up draws from the drainage tube lower end again and to draw from the upper port that is positioned at barrel under the air pump gas pressure, carries out gasification reaction with reaction mass in the reaction tube.Control accuracy is higher.At the access position of air inlet pipe or be extended down to other manual control and the control valve of safety valve or manual overvoltage venting usefulness be set the position separately easily.

The right shown in Figure 2 is identical with Fig. 1, for for simplicity, reaction tube is taken away, and a replaceable last shoulder cover makes and connects well, and other uses whole storage tank 1 instead as retort.Additional storage tank 14 is used to place soup and places the next door, jar cooperates therewith to establish one in addition and comprise conduit 15, connects the sprayer unit of mouth 16.Feeding device is established in the top of additional storage tank, by set check valve 17, and vent valve 19 (c position), balanced valve 21 (d position), reinforced cover 20 is realized dynamically reinforced operation task.Connecing of d, e, b place is connected to three-way pipe between the mouth.So just, constituted a kind of multiduty sprayer.It participates in gasification reaction by hand air pump control feed.The dynamically dosing of this device, auto spraying, easy to assembly, use for selecting under the different situations.

The course of work of the present utility model and occupation mode are summarized as follows: 1, sprayer shown in Figure 2 is suitable for large tracts of land and sprays, and is dynamically reinforced, works continuously.It is pressed into air by hand air pump (tube), and compressed air enters loading hopper, material storage tube from appendix, the sulfuric acid liquid level of compressing in the material storage tube, and acid solution is promoted to upper port from drainage tube and flows to the storage tank 1 and the reaction of material carbon ammonium along barrel, produces carbon dioxide; Close under the condition at a place valve 7, carbon dioxide arrives the additional storage tank 14 that c place valve nozzle enters powder charge liquid through the valve nozzle at retort shoulder b place by threeway, the compressing liquid level, with soup at the bottom of the jar introducing conduit 15, connect mouth 16 and spray through sprayer unit; Simultaneously, the retort internal pressure progressively tends to be balanced with the liquid level pressure of material storage tube 10 tops, and the retort internal pressure descends gradually, and then the air pressure on acid solution surface promotes feed flow, continues to take place chemical reaction.When being not enough to support that liquid level promotes drainage in the drainage tube, the material storage tube internal pressure just need continue manually to inflate with replenishment control air pressure.Can utilize the manual or automatic deflation (electing 0.28Mpa as among the automatic control threshold value embodiment) of safety valve during overvoltage; Dynamically during dosing, close balanced valve 21 earlier, open vent valve 19 bleeds, check valve 17 is closed voluntarily because of pressure reduction, open reinforced cover 20 again, inject soup, close vent valve 19 then, open balanced valve 21, form isobaric condition, soup is opened check valve and is entered in the jar under the effect of deadweight.In whole reinforced process, can not influence a jar internal pressure, can not influence ongoing spraying duty.The double-pot type structure should be used for vehicle-mounted, and freedom of movement is easy to operate.2, small size sprays operation and can adopt single-pot structure shown in Figure 1.Their action principle is identical.Difference is that chemical reaction is placed in the reaction tube 11 carries out, because capacity is little, the material containing amount is limited, and just in time the operation that sprays with the small size scope is complementary.Though the uninterruptedly operation of this sprayer until having sprayed, can not dynamically be fed in raw material.Although the acid solution in the 3 above-mentioned sprayers is fool proof when manipulating, do not implement spraying if still do not wish to adopt the method for chemical reaction, then can remove the charging in the material storage tube, directly use the hand air pump device to operate, the valve nozzle at b position is closed get final product by traditional mode; Make the acid solution liquid level identical with jar internal pressure if isobaric condition is set, the assurance acid solution is not overflowed, and then can not remove charging yet, the sealing air inlet mouth of pipe, and air inlet pipe is displaced to also can direct control on a place valve nozzle.

Example structure shown in Figure 3 can be used to directly dynamically liquid feeding.It is a loading hopper 24 in the middle straight tipping of its bung 20, and the side of bucket pipe is provided with a check valve 26 again under hopper.Other structure is constant.The 25th, sealing ring.The port is established washer sealing in addition.The course of work of this device is: install on the bung after the hopper, (referring to Fig. 2) shuts balanced valve 21-and opens vent valve 19 bleeds-pour soup into and push check valve open toward loading hopper, soup enters feed pot 18, open balanced valve 21 to fill it up with-shutting vent valve 19-, this moment feed pot and additional storage tank internal pressure balance, instead borrow deadweight to push check valve 17 open the soup in the closed check valve-feed pot of loading hopper bucket pipe, finish overall process.

Practice shows by sulfuric acid: agricultural carbon ammonium: the mode of pesticide liquid=0.5: 1.2: 100 disposes, and by the condition production of operating pressure 0.1-0.25MPa, product should reach goal of the invention and put into practice requirement.
