    The supply pipeline A has de-branch lines 6.7, and in the branch line 6, a shut-off valve 8 and a flow control valve 9 are installed in series. Thus, a shut-off valve 10 and a flow control valve 11, 6, 7 are connected in series in the toroidal annular space 12 of the annular gutter 13, which is capable of an internal quilting 14. forming a rewind. Annular g: growth 12 is blocked by a cover 15, equipped with a 1G cylindrical screen, setting to form an internal wall 14 of a gap 17 in the cylindrical space 18, with an upper cutting, i.e. hushchuu5 to the inner wall 14. 18 adjoins a funnel-shaped receiver 19, a pipe 20 is connected to the lowest point to discharge the resulting liquid mixture leading to a pump 21, which is driven by an electric motor 22 and serves to feed the mixture to the supply pipe 23. E supply pipe 23, a running valve 24 is installed, from which the pipeline 25 and the pipeline pipe 26, are connected to the suction pipe 9.7 of the discharge pump 28,
    Pipeline 25 enters the first chamber 29 of an additional mixer 30, which consists (in this case of three successively located chambers 29, 31, 32, equipped with driven motors 33,34,35 pumps 36,37,38. The chambers are separated by each other from each other by partitions 39 of varying heights, the height of partitions 39, starting from the first chamber 29, increases with each subsequent chamber, so that the partition between the penultimate and the last chambers has the greatest height. installed so that the liquid mixture is sucked at the bottom of the chamber.The supply pipes 43,44 of pumps 35,36 are divided into two lines. One line 45 with a large cross section leads back to the camera to its bottom, where the intake pipe of the corresponding pipeline is located. 46, with a smaller cross section, the S3 comes in a subsequent chamber, and its outlet opening is located above the maximum possible liquid level in this chamber. In this case, only the continuously required amount of the liquid mixture is transported from the chamber to the chamber. Due to the separation of the flow, the largest part of it remains in the state of constant circulation, since
    due to the different height of the partitions between the chambers, there is always a return overflow to the first chamber 29. This achieves intensive mixing
    with sufficient residence time and dissolution. Switches 47.48.49 located in the chambers control the minimum suction pipelines located above the intake ports.
    0 40,41,42 level of the liquid mixture of each chamber. If in one of the chambers the minimum level is reached, the pump belonging to the previous chamber is turned on. The switch 50 controls the maximum liquid level in the additional mixer 30. The switch 50 is therefore installed in the first chamber 29, when it reaches the maximum level it switches off the pump 21.
    0 In the funnel receiver 19, switches are provided for 51.52 to control the level of the liquid, which, when a certain level is decreased or increased, turn on or turn off the electric motor 5.53.54 of pump 2, the dosing device 55 for solids and the dosing device 56 for the liquid component. For solid and liquid components,
    0 more dosing devices.
    The supply pipe 57 of the pump 38 is also divided into two lines. Line 58, like Line 45 of pumps 35, 37, leads back to
    5 to the bottom of the chamber, while the other line 59 is connected to the suction pipe 27 of the discharge pump 28. The line 59 can be shut off by means of the flow valve 60, the discharge pump 28, preferably driven by the internal combustion engine, through the feed pipe 61, in which a switchable two-way switch is installed valve 62 is connected to the working bodies (not
    5 are shown), for example with spray devices, in a certain operating position of the valve 62. In a different position of the valve 62, the feed pipe 61 is connected to the suction pipe 27
    0 through the return line 63, and in this position the electric motors of the 5,22,33,34,35,53,54 pumps 2,21,36,37,38 and the dosing devices 55,56 are turned off.
    5 To the outlet of the funnel receiver 19, an additional pipe 64 is connected to discharge the obtained liquid mixture, equipped with a switchable valve 65, in one working position of which the pipe is blocked. The pipe 64 is connected directly to the suction pipe 27 of the discharge pump 28.
    The solids dosing device 55 mainly consists of a feed funnel 66 filled with an impurity solid, the solid being kept in motion by a rotor 67 and a dispenser 68 in the bottom of the feed funnel 66 equipped with a screw 69, driven by adjustable electric motor 53.
    The dosing device 56 for the liquid component consists of a delivery unit 70, driven by an adjustable electric motor 54 and connected to the tank 71 through a check valve 72. It is advisable to install two consecutive vertical tanks 71, each of which is equipped with a check valve 72 In this case, one tank 71 serves to receive solvents, and the other to receive emulsifiers or in both tanks contains a mixture of solvent and emulsifier, as well.
    The two-way valve 62 is provided with an electrical switching mechanism (not shown) associated with the actuator. Electric lines have been laid between the switching mechanism and the electric motors of the device.
    The device works as follows.
    The pump 2 draws water from tank 3 and transports it via supply line 4 to branch lines 6 and 7. Flow control valves 9, 11 are tuned to flows of various sizes, with flow control valve 9 preferably set to low flow, as is required to deactivate various devices and the flow control valve 11 to the high flow, as required for decontamination of the terrain. When the shut-off valve 10 is closed and the shut-off valve 8 is open, only a weak flow enters the annular space 12 of the chute 13, and when the shut-off valve 8 is closed and the shut-off valve 10 is open, a much larger flow is supplied to the chute 13 than is required to deactivate the area . To deactivate the terrain, it is preferable to open both shut-off valves 8,10. Thus, for example, the flow control valve 9 is set to a liquid flow rate of 20 l / min, and the flow control valve 11 is set at a flow rate of 180 l / min. Instead of flow control valves 9, 11, flow meters can also be used, through which
    You can adjust the number of revolutions of the motor 5.
    Due to the tangential flow of water into the annular space 12 from line b and / or 7, a rotational flow is created in it. With sufficient filling of the annular space 12 and further supply of water through the upper chamber wall 14 enters the cylindrical space 18, as well as in the funnel receiver 19, while maintaining its rotational flow. In such a rotating stream, the amount of solids determined per unit time, such as bleach, is now fed from above from the metering device 55. When this happens, it gets on the free surface of the water circulating in the funnel-shaped receiver 19, is captured by it and dissolves.
    Thus, the amount of solvent and / or emulsifier determined per unit of time is fed into the rotating water flow from the top of the metering device 56 for the liquid components, which are mixed with it, as well as with the bleach. With the help of well-known devices, such as sieves, centrifugal separators, etc. (not shown), it can be achieved that lumps of bleach do not enter the pump 21 through the suction line 20.
    Through the pump 21, the water / chemical mixture at a certain operating position of the valve 21 in the supply pipe 23 is fed to the auxiliary mixer 30, where it is circulated in the manner described. From here, through a supply line 59 supplied with a shut-off valve 60 and a suction line 27, the liquid mixture flows to a discharge pump 28, which is connected to a spray unit for decontamination.
    If it is necessary to interrupt the spraying process of the mixture obtained in the device, the valve 62 in the flow pipe 61 of the discharge pump 28 switches to the circulating position, so that the discharge pump 28 circulates the amount of mixture remaining in the device. In this operating position of the valve 62, an electrical switching mechanism associated with its actuator ensures that all electric motors are turned off. Turning on or on again is performed by means of valve 62 and an electrical switching mechanism connected thereto.
    By means of additional, randomly controlled switches (not shown), individual motors can be turned on or off.
    Thus, various operating states of the device are possible.
    In the first operating state, all electric motors operate. In the manner described, a mixture of water, solid and liquid components is obtained, since the valve 24, as shown in the drawing, is in such a working position that the liquid mixture flows through the additional mixer 30.
    In the second operating state, a mixture is prepared consisting only of solids from a feed funnel 66 and water. In this case, the electric motors 5 and 22 of the pumps 2 and 21 and the electric motor 53 of the dosing device 55 operate, and the directional valve 24 is in a working position (not shown), in which the pipes 23,26 communicate with each other. The valve 65 is in the open position, so that the funnel receiver 19 and the discharge pump 28 are also connected via a pipe 64. Thus, the device operates at maximum power, i.e. delivers to the spraying apparatus the maximum amount of the liquid mixture.
    In this operating state, it is also possible that the valve 24, as shown in the drawing, is additionally included, so that the mixture is passed through an additional mixer 30. To do this, the electric motors 33,34,35 pumps 36,37,38 are additionally included.
    In the third operating state, no solid substance is added from the feed funnel 66, i.e. only the liquid component is mixed with water. In this case, the electric motors of 5,22.54 pumps 2.21 of the metering device 56 are turned on. Valve 24 connects the feed pipe 33 of the pump 21 directly to the suction pipe 27 of the discharge pump 28.
    And in this case it is possible that the valve 24 is switched to such an & position that the liquid supplied through the pipeline 23 flows to the discharge pump 28 through an additional mixer 30. For this purpose, the electric motors 33,34,35 pumps 36,37 cameras 29,31,32.
