Description

The invention relates to mobile spraying devices, for example, bleach solution, consisting of a tank mounted on a carriage with an aperture; a shaft through it, which is equipped with agitators and a centrifugal single-disk or diskless pump driven by an engine mounted on the same carriage .

In the proposed mobile spraying device, the pump discharge nozzle is equipped with a three-way valve for supplying water through a pipe to the upper part of the tank, which makes it possible to control the production rate of a certain concentration, as well as to circulate water for flushing the tank.

The drawing shows a diagram of a mobile spraying device.

On the trolley 7 is installed tank 3, through which the shaft 8 of the centrifugal pump b, driven in rotation by transmission from the engine / mounted on the trolley 7.

Under the tank 3, the centrifugal pump 6 is located so that its axis of rotation is vertical and the wheel rotates in a horizontal plane. The suction pipe 9 of the pump is connected directly to the tank 3 and is a wide mouth, and the discharge pipe / a is used to connect to the sprayer hose for spraying, spraying the bleach solution.

The tank 3 may be of any shape satisfying the condition of a smooth exit of the lime solution into the pump, for example, a cylinder with a conical bottom connected to the pump.

The centrifugal pump b can be single-disk, as shown in the diagram, or it can be completely diskless, and with the blades alone, mounted on the wheel hub, all of this depends on the solution density of 6m.

An ordinary centrifugal pump can be supplied for spreading and spraying liquid milk of lime, which, however, is not suitable for lime paste.

Bleach can flow directly into tank 3 in a sufficiently spaced form, or mill 2 can be placed directly above the tank to grind (grind or powder) bleach, from where it flows into the tank.

In tank 3, agitators W are mounted, for example, in the form of blades on the shaft 8 of the pump, coming from the pump through the tank to the upper drive.

Transmission movement from the engine. 7, pump b, mill 2, as well as to the truck semi-rolls, if the whole device is made movable, is produced in any way: gear or belt drive, Gall chains, etc. Drive or other types of gear can be equally well above the tank and under the pump.

The water is supplied to the tank 3 through the valve Z installed on the tank and used to adjust the water supply to the tank.

At the start of operation of the device, the corresponding density of the mixture cannot be obtained immediately and, consequently, the 4epiS3 ejecting pump channel into the discharge nozzle and the hose will initially get almost pure water. To eliminate this, the pump nozzle 1a of the pump is equipped with a three-way valve 5, one of the passages of which connects the pump nozzle / s with the nozzle 2a attached to the hose (sleeve) for spraying. The other passage of the crane, perpendicular to the first one by means of pipe 4, is connected to the tank. At the start of operation of the device, the valve 5 is turned so that the passage to the hose is closed, and the passage to the tank through the pipe 4 and the passage 3 of the pump are open. In this case, when starting up the pump will pump water with lime from the tank back to the tank in a circular.

As new portions of lime come into the tank with the tap 5a closed for water, its solution will become thicker and thicker. When the solution reaches the appropriate concentration, turn the valve 5 so that the passage into the pipe 4 is closed, and

The passages from the pump to the hose were open. After that, it will be possible to start spraying without difficulty, if the lime is falling asleep in the tank, i.e., the work of the mill, as well as the flow of water through the tap into the tank, will be properly adjusted. Crane 5 also serves as a dl. rinsing the tank.

Since the pump flow, mill operation, and conditional water flow through the faucet can be calculated with a sufficient degree of accuracy, once adjusted the device, with proper care, will work correctly during the entire spraying time. With some skill, the above mentioned adjustment takes only a few minutes.

The device makes it possible to suspend spraying without stopping the engine by turning the three-way valve 5 and the crane Over to supply water. -.

The subject matter of the invention. A mobile sprayer consisting of a tank mounted on a carriage with a shaft passing through it, equipped with agitators and a centrifugal single or diskless pump driven by an engine mounted on the same carriage, characterized in that obtaining a certain concentration, as well as creating water circulation for flushing the tank, the discharge port of the pump is equipped with a three-way valve 5 that communicates pipe 4 with the upper part of the tank.
