Description

The utility model relates to devices designed for fine atomization of water in the form of an aerosol. Such devices are used in various industries where there is a need to humidify the air for a long time, in finely dispersed spraying of water in the air, spraying of ingredients dissolved in water, dust suppression, and air cooling. A water spray can be used in agriculture to increase air humidity, for example, in greenhouses; for spraying liquid fertilizers; for the introduction of pesticides in the fight against plant pests, maintaining moisture and treatment from pests of livestock farms. In public utilities for the purpose of sanitizing premises, dust suppression, treatment with various insecticides of stocks, cooling premises and small areas. Due to fine atomization (droplet size does not exceed 40 microns), the sprayed liquid hangs in the air of a closed room for 5 hours, which allows using the water spray also for disinfection, disinsection, deratization, for processing various premises, for example, warehouses, barns, granaries, elevators, offices, cinemas, hospitals, schools and the like.

The known design of a water spray (fogging agent) UA patent No. 4549 C1, "fogging installation", bull. No. 7-1, 1994). The main elements of the fogging installation according to the UA patent No. 4549 C1 are a water tank, water-air tanks, air valves, a hydraulic pump, sensors, switches, spray nozzles. The design of the fogging installation according to UA patent No. 4549 C1 is bulky, complex, heavy, overloaded with rather complex and dimensional units and mechanisms.

Also known is the design of a fogging device (water spray) (patent UA No. 16567 A or copyright certificate SU No. 1540735, "fogging installation", Bulletin of the USSR No. 5, 1990). The design of the plant according to the patent SU No. 1540735 is very close to the above design according to the patent UA No. 4549.

The disadvantages of these two designs are almost identical.

Also known is the design of a fogging device (water spray) (patent UA No. 50466 A, "mechanical fog generator", bull. No. 10 2002), which contains a power unit assembled on a frame and fixed on a car chassis, a radiator for cooling the power unit, a tank for working fluid , drive gearbox, turbocharger, spray device, as well as connecting hoses, valves and taps. The work of a mechanical fog generator mounted on a frame and fixed on a car chassis is carried out when the power unit is operating, which rotates the turbocharger through a gearbox, and with a compressor supplies compressed air to the receiver, which displaces the working fluid from the tank and supplies it to the sprayer. The disadvantages of the design of the fog generator according to the UA patent No. 50466, as in the case of the above-mentioned analogs, are the complexity, high cost, cumbersomeness, and also limited possibilities for use in small or enclosed spaces.

Also known is the design of a fogging device (water spray) (RF patent for utility model No. 76773), selected as a prototype, which consists of a non-removable spray system mounted on a frame. The disadvantages of the fogger design according to patent No. 76773 are low productivity, limited functionality due to the non-removable chamber of the spraying system, lack of protection against short circuits of electrical wires and the electric motor, poor protection against mechanical damage, premature wear of the electric motor, the likelihood of frequent clogging and damage to the water spray impeller caused by the lack of an air filter.

The problem solved by the claimed utility model is to create an easy-to-use, efficient, maintainable, durable, functional, efficient and inexpensive electric water sprayer.

The task is achieved by the fact that the water spray is electric, contains a frame made of a metal pipe sheathed with a metal sheet, a plastic water tank with two necks, mounted on the frame. The chamber of the water spraying system is a removable metal accumulator tank cut into two parts with a tubular handle and ears welded to it along the edges of the sawn parts of the tank. The air filter system is presented in the form of a rubber gland with a metal plate attached to it, through which an air filter is attached to the back cover of the accumulator tank. A working part of the spray system is built into the accumulator tank, consisting of an electric motor with a built-in fan, attached by a hydraulic cuff to the accumulator tank, a round plastic spray impeller with blades arranged in two tiers, with an inner tube, a polyurethane pipe with a tap for water supply, a rubber gland , inserted into the front cover of the accumulator tank and a metal fastener, by means of which the plastic impeller of the sprayer is attached to the front cover of the accumulator tank. The power supply system consists of a switch - an electric double circuit breaker connected to the electric motor by a two-wire electric wire, a plastic fastener that fixes the electric wire. The water supply system to the accumulator tank consists of a plastic water tank with two necks, a water supply valve and a polyurethane pipe attached to it.

The technical result, which the declared utility model is aimed at, is a sufficient adjustable productivity of the apparatus (water consumption up to 25 liters per hour), wide functionality (use of both a stationary apparatus and a mobile system for processing hard-to-reach places) in the areas of public utilities. agriculture, agriculture, including animal husbandry.

The hydroaccumulator tank 6 is sawn into two parts, which are interconnected by metal ears 9. An electric motor with a built-in fan Ø 130 mm 5 is attached inside the hydraulic tank 6 by means of a hydraulic cuff 4. A round plastic impeller 3 is attached to the front cover 2 of the hydroaccumulator tank 6 by means of a metal fastening 23. Between the round plastic impeller 3 and the front cover 2 of the accumulator tank 6, a rubber gland is inserted 1. A metal handle 24 is welded to the accumulator tank 6. The air filter is attached to the back cover of the accumulator tank 6 by means of a rubber gland reinforced with a metal plate 7. The water supply system is presented a plastic tank 13, a tap 20, a polyurethane pipe 19, a plastic fastener 22 for a polyurethane pipe. The power supply system consists of a plug of an electric wire 18, an automatic switch 15, a two-wire electric wire 11 and a plastic fastening of an electric wire 22. The fixing system of the accumulator tank 6 consists of fastening bolts 21 and a metal strip 12 with slots for fastening bolts 21.

The electric water sprayer works as follows. The electric engine 5 pumps air into the accumulator tank 6, the air enters through the air intake openings 8 of the rear part of the accumulator tank 6. High pressure air passes through the impeller 3 of the atomizer, into which a polyurethane pipe 19 is inserted for water. Due to the air pressure, water from the tank 13, passing through the tap 20 and the polyurethane pipe 19, is sucked into the impeller 3 and further, passing through the gland 1, is finely dispersed in the form of an aerosol. By means of the fastening bolts 21 and the metal strip 12 during the operation of the sprayer, it is possible to change the angle of inclination of the water torch from 0 to 90 degrees. During the operation of the sprayer, it is also possible to disconnect the accumulator tank 6 from the metal frame 16, and holding the accumulator tank 6 by the handle 24 direct the jet of the water torch in any direction to process hard-to-reach places.

The implementation of the sprayer, depending on the areas where it is necessary to spray water, may include, for example: installing an engine of a different power, changing the length of the polyurethane pipe for water supply, installing wheels on a frame, sequentially installing two or three axial fans in the casing (for cases, when a higher power fogger is needed).

But in any embodiment of a particular implementation of the sprayer, its mandatory elements are an electric motor, a polyurethane pipe for water supply, a plastic impeller of a water sprayer.

The sprayer is manufactured using components and assemblies commercially produced in the Russian Federation in its design.

The proposed water spray is simple to manufacture and operate, it is repairable enough, because allows to carry out repairs and maintenance to persons who do not have special technical knowledge, as well as, in view of the production of main components and assemblies in the Russian Federation, to supply spare parts as soon as possible.
