Description

The utility model relates to the field of technical means for disinfecting during the elimination of the consequences of the use of weapons of mass destruction, industrial accidents and focal infections, and can be used to decontaminate, degass, and disinfect territories, buildings, structures, and equipment with liquid solutions.

A well-known automobile filling station (see the book by A. S. Zubkin "Disinfection of territories, structures and vehicles exposed to weapons of mass destruction", "Atomizdat", Moscow, 1965, p. 57), made on the chassis of the ZIL- 157, on which equipment is mounted consisting of a tank for liquid solutions, a pump with a mechanical drive, a manual pump, a piping system, as well as removable equipment and accessories, including manifolds, intake and dispensing hoses, nozzles, water cannons (straight) and with etc.

Known modernized automotive filling station (ARS), made on the chassis of a more modern car ZIL-131 (see "Gas station ARS-14. Technical description and operating instructions", M., "Military Publishing", 1987), which are equipped chemical units of the army of the Russian Federation at present, also consisting of a pump with a mechanical drive, tanks, manual pumps, pipelines, removable equipment and accessories. The station can be used to equip small shells with autonomous devices (cylinders) with liquids, for example Avtomaks pneumatic sprayers used for disinfection and degassing (see the aforementioned book of A.S. Zubkin, p. 74), and consisting of a spray bottle a piston-operated air pump with a manual drive to create pressure in the cylinder, a hose with a brush for spraying and rubbing the solution on the treated surface. A rack can be installed on the chassis for placement and transportation of cylinders, and for filling

compressed air cylinders pre-equipped with solutions, equipped with an air system with a compressor.

Known ARS have the following significant disadvantages:

- the mechanical drive of the pump for pumping working fluids has significant overall mass characteristics;

- manual drive of an air piston pump for pumping compressed air into cylinders requires constant physical effort, especially when processing large areas and a large number of pieces of equipment;

In addition, the mechanical drive of a pump for pumping liquids and an air compressor for pumping compressed air into stand-alone devices in a filling station installed, for example, on the chassis of a multi-purpose vehicle Ural-532301 with an 8x8 wheel arrangement, is possible provided that 3 cardan and 2 intermediate shafts are used , closed speed reducers, synchronized on-off mechanism of the units, which ultimately reduces the performance characteristics of the machine as a whole, such as cross-country ability, productivity increases the time for maintenance and repair, and in addition, it will have significant volumetric mass characteristics.

This useful model solves the problem of improving the technical characteristics of disinfectants. The technical result achieved by the utility model is the use of a hydraulic method for transmitting torque from the chassis power take-off to a pump for pumping liquids and an air compressor for pumping compressed air into portable cylinders.

The problem is solved in that the said compressor and the pump for pumping liquid solutions are equipped with a volumetric hydraulic actuator, the elements of which are placed on the frame under the cargo platform and include a high pressure pump driven by the power take-off of the automobile chassis, pressure pipes of hydraulic motors equipped with a three-position distributor with the possibility bypassing the working fluid to drain into the tank in the neutral position

the distributor, and the connection of the high pressure pump with one or the other hydraulic motor - in working positions, while the hydraulic actuator is equipped with an autonomous cooling system with a radiator and an electric fan for blowing it.

Analysis of the distinguishing features of the proposed technical means showed that:

- the supply of the compressor and the pump for pumping liquid solutions with a volume hydraulic actuator ensured small overall mass characteristics of the drive compared to the mechanical one, increasing smoothness of work and endurance from overloads;

- the compact arrangement of the hydraulic actuator on the chassis frame under the cargo platform allowed to free up space for placing more working equipment on the platform, increased the volume of transported liquid solution, improved maintainability, and reduced the time for maintenance of the machine as a whole;

- the use of an autonomous cooling system with a radiator and an electric fan for blowing it, supporting the working fluid in a given temperature range, provided continuous operation of hydraulic motors and a pump with maximum efficiency, which increased the operating characteristics of the drive.

The proposed technical means for disinfection is performed, for example, on the chassis 1 of the Ural-532301 multi-purpose vehicle with a wheel arrangement of 8 × 8 (see Figs. 1, 2). On the loading platform, working equipment for decontamination, degassing and disinfection, including

a container 2 for liquid solutions, a pump 3 and a piping system 4 for supplying them, a rack 5 for accommodating portable cylinders 6 for liquid solutions and an air system with a compressor 7 for filling compressed cylinders 6.

Pump 3 and compressor 7 are equipped with a volume hydraulic drive, the elements of which are placed on the frame under the cargo platform and include a high pressure pump 8 driven by the power take-off of the automobile chassis, hydraulic motors 9, 10, oil tank 11 (see Fig. 3), filter 12 , radiator 13 with electric fan. Pressure lines 14, 15 of hydraulic motors 9.10 are equipped with a three-position valve 16.

The hydraulic actuator also includes a block of back-safety valves 17 (see Fig. 4), which supports the required power of the hydraulic motors 9, 10 and their recharge when the supply of the working fluid is stopped, check valves 18, 19, preventing the rotation of the motor shafts in the opposite direction, the valve safety 20, which protects the system from overloads, valves 21, 22 used when setting the safety valves of block 17 and the unloading valve 23. Radiator 13, valve 16, block 17, valves 18, 19, 20, 23, valves 21, 22 are set to one plate 24.

To control the pressure, gauges 25, 26 are included in the system (see Fig. 5). The chassis also contains removable equipment and accessories, including headers, intake and dispensing hoses, nozzles, spray nozzles (straight) and with brushes (not shown in FIG.).

Work.

Liquid solutions are transported on a car chassis 1 in a container 2 to the place of decontamination, degassing and disinfection of territories, buildings, structures and equipment. Using a pump 3 and a piping system 4, solutions are supplied to treat infected surfaces.

When charging a group of portable cylinders 6, they are pre-equipped with solutions 3 using a pump 3, after which they are filled with compressed air using a compressor 7 of the air system.

The hydraulic actuator provides energy for the working fluid to the hydraulic motor 9 of the drive of the pump 3 for supplying liquid solutions and the hydraulic motor 10 of the drive of the compressor 7 in the sequence according to the hydraulic circuit diagram.

From the tank 11, the working fluid is pumped by a high pressure pump 8 to the distributor 16 through the pipe 27, and through the pipe 28 connected to it, to the safety valve 20, connected to the drain pipe 29, through which the working fluid is supplied through a radiator 13, an unloading valve 23, a filter 12 back to the tank 11 in case of pressure increase in the pipelines 27, 28 above the maximum permissible.

The spool (Fig. Not shown) of the distributor 16 has three positions: neutral and two workers. When the spool of the distributor 16 is in the neutral position, supplied by the pump 8 through the pipe 27, the working fluid passes through the drain channels of the distributor 16 and through the pipe 30 connected to the drain pipe 29 through the radiator 13, the discharge valve 23, the filter 12 enters the tank 11.

When the valve spool 16 is in one of the operating positions, for example, the upper electromagnet of the distributor 16 is turned on, supplied by the pump 8 through the pipe 27, the working fluid passes through the channels of the distributor 16, the back-safety valve block 17 and the pipe 31 through the open valve 21 and the check valve 18, enters the hydraulic motor 9 of the pump drive 3 for pumping liquid solutions, and then through the drain pipe 29 through the radiator 13, the unloading valve 23, the filter 12 is discharged into the tank 11.

When the lower electromagnet of the distributor 16 is turned on, the working fluid also passes through the channels of the distributor 16, the back-safety valve block 17 to the pipe 32 and through the open valve 22 and the check valve 19 enters the hydraulic motor 10 of the compressor 7, and then through the drain pipe 29 through the radiator 13, the discharge valve 23, the filter 12 is discharged into the tank 11.

The pressure of the working fluid in the pipe 31, providing the necessary power of the hydraulic motor 9, as well as protecting it from overloads

they are carried out by a safety valve 33, which is part of the back-safety valve block 17. The safety valve 33 is set to the maximum permissible pressure in the pipe 31 with the closed valve 21, and the pressure is monitored using a pressure gauge 25.

The pressure of the working fluid in the pipeline 32, which provides the necessary power of the hydraulic motor 10, as well as its protection against overloads, is carried out by a safety valve 34, which is part of the back-safety valve block 17. The safety valve 34 is set to the maximum permissible pressure in the pipeline 32 of the working fluid when the valve is closed 22, control of the pressure value - by pressure gauge 25.

The excess fluid is drained through the safety valves 33, 34 through a pipe 35 connected to a drain pipe 29.

When the supply of working fluid to the pipeline 31 is stopped, when the spool of the distributor 16 is moved from the working position to the neutral position, the hydraulic motor 9 by inertia starts to work for some time in the pump mode, therefore, to exclude cavitation processes resulting from this, the working fluid from the drain pipe 29 through the pipeline 35 through the non-return valve 36 of the back-safety valve block 17, and then through the pipe 31 through the valve 21, the non-return valve 18 energizes the hydraulic motor 9 until it stops completely.

When the supply of working fluid to the pipeline 32 is stopped, the spool of the distributor 17 is moved from the working position to the neutral position - the hydraulic motor 10, as in the case of the hydraulic motor 9, starts to work for some time by inertia in the pump mode, and the occurrence of cavitation processes is excluded by feeding the hydraulic motor 10 the fluid coming from the drain pipe 29 through the pipe 35 through the check valve 37 of the block back-safety valves 17, and then through the pipe 32 through the valve 22, the check valve 19 to a complete stop ovki motor 10.

When the hydraulic actuator is operating on a cold working fluid in the drain pipe 29, the pressure rises, which leads to the opening of the discharge valve 23, and the liquid enters the filter 12 through the radiator 13 and the discharge valve 23 at the same time.

As the working fluid warms up, the pressure in the drain line 29 decreases and when the liquid reaches a temperature of + 50 ° C, the unloading valve 23 closes and the entire fluid flow passes only through the radiator 13.

With a further increase in the temperature of the working fluid to + 73 ° С, the radiator 13 is automatically turned on, which continues until the working fluid reaches a temperature of + 50 ° С, after which it is also turned off automatically. Monitoring the increase in pressure in the drain line 29 is carried out by a manometer 26.

The working fluid is cleaned by the filter element 38 that is part of the filter 12, as the filter element 38 becomes contaminated, the pressure in the drain pipe 29 rises, which opens the safety valve 39, also included in the filter 12, and the liquid stream enters the tank 11, bypassing the filter element 38 through the safety valve 39.

Thus, the task is solved to increase the technical characteristics of disinfectants.
