Description

DISINFECTION [EVENT

FIELD OF THE INVENTION The present invention relates to disinfection devices, in particular to aerosol spray disinfectors, which are used for spraying and disinfection of chemicals.

TECHNICAL LEVEL

The world-wide spraying device for spraying chemicals in gardens, gardens, and premises has been invented for a long time, but over time and with new demands, new structures have been developed that are characterized by new features and exceptional designs. Known Japanese patent no. JP6219904, published 1994. August 9 This patent describes an ethanol-filled reservoir consisting of a plastic reservoir housing, an ethanol-carrying disinfecting system, an aperture in the upper portion thereof, a spray-type air pump which can be sprayed by spraying the ethanol from the sprayer. Although this disinfectant is easy to use, it is small in size and is designed to spray only a very small area / volume. Keep the button pressed to operate the sprayer. However, this is a single-use device because the ethanol contained in said plastic reservoir ends and the addition of the new ethanol portion of the refill option does not provide.

A Japanese patent no. JP7008237, published 1995. January 13 It describes a quick-action system for disinfecting and chilling food. Initially, food on the conveyor is sprayed with water enriched with ozone and then dried with a stream of sterile air. This type of conveyor is placed in a semi-enclosed chamber, i. the camera has only inlet and outlet openings: on one side the conveyor is supplied to the processing chamber and on the other hand, after processing, it is directed to further operations, eg packed. However, such a disinfection system is not mobile and is designed to disinfect food only in a small area. 2 A known French patent no. 609603358, published 1997. March 29 This patent describes a method comprising a spray device and a spray material. The particular feature of this method is that in said device the disinfectant is mixed with the washing liquid and the sprayer not only sprays the chemicals, but is also rinsed with a liquid wash, i.e. not clogged. The spray device is also described in this patent. This spray device is mobile and can spray a larger area compared to the above-mentioned analogues, but it is not for disinfecting the premises, but for items that are placed on a special base under the spray. A well-known American patent no. WO2008147866, published 2008. December 4 This patent describes a method and device for creating an ozone cloud. It is a clumsy stationary device with injectors inside, one of which is spraying water, the other is ozone, and the third is compressed gas. All these sprinklers are directed to each other, and water, ozone and compressed gas mix during operation. In this way, a cloud is created which, depending on the layout and directions of the sprinklers, can be directed outward in a certain direction / angle. This type of device is designed to disinfect a small / no room / room. The cloud created by such a device rises slowly upwards, the particles cool down quickly and descend downwards.

The closest to the prior art is Japanese patent no. JP2006095345, published 2006. April 13 This patent describes a spray apparatus adapted for spraying premises, gardens, hedges and the like. The device itself is compact, mobile (on wheels) and can spray the substance at the desired angle. However, this device is only convenient when spraying a small room, area or the like, and spraying this type of device on large areas, large volume rooms, and relatively high premises is not appropriate. PRINCIPLE OF THE INVENTION The object of the present invention is a lightweight (about 40 kg), mobile (on wheels) spraying device powered by a single-phase standard power network (220 V) capable of spraying a relatively large amount of chemicals (up to 120 liters / hour). ), the flow of a mixture of chemicals can reach up to 60 m in a horizontal direction. This facility can be used to disinfect large areas, large rooms and large cubic spaces (up to 8800 m3 / h), such as livestock or bird farms, large warehouses, large cubic greenhouses, hotels, food industry production facilities, other large establishments.

An essential feature of the present invention is that the relatively high volume of chemical spraying is not achieved by increasing the electrical capacity of the device (vice versa: only a standard single phase 220 V electrical network is used), but because of the internal design of the device and their mutual alignment, which significantly reduces the overall system performance. resistance to the flow of the mixture in all air / chemical mixture flow, passage and spray systems / parts.

THE BEST [LIFELONG LEARNING OPTIONS

As is well known, there are many forms and types of devices in the world for spraying chemicals. Generally speaking, this type of equipment has a wide range of uses: spraying chemicals in gardens, gardens, animal complexes, poultry farms, warehouses, greenhouses, hospitals, hotels and other premises. The chemicals can be different: to disinfect a certain space or to give it certain properties, such as flavoring. One of the most important parameters of all similar devices of this type is the spraying speed of the prepared mixture, which usually does not exceed 8-10 liters per hour. The essential feature of the present invention is that it can spray up to 120 liters per hour of a mixture of chemicals. At the same time, the device is mobile, relatively lightweight (its weight without chemicals is only about 40 kg), easy to operate (it can easily be operated by one person). In order to increase the rate of spraying of chemicals, technologists usually increase the power supply of the unit, but then the simple single-phase (220 V) power supply is not enough and a much more dangerous two- or three-phase (380 V) power source is used. However, increasing the electrical power of this type of equipment does not solve the problem, as it will significantly increase the resistance (impedance) resulting from the flow of the mixture of chemicals. This can cause system blocking and burnout of electronic blocks. The device of the present invention is not only capable of dispensing substantially more (about 10 times) the amount of a mixture of chemicals in the same time, but is also powered by a standard single-phase power supply (220 V), but also because the maximum length of the spray material in the horizontal direction reaches up to 60 meters. These features are ensured by the interior design of the unit, which consists of a set of specially designed and adapted / matched construction elements. This set of structural elements ensures low resistance when the mixture of chemicals passes through the entire construction of the device: from the beginning (the chemical reservoir) to the moment when the mixture is sprayed outwards.

FIG. Figure 1 shows a general scheme of a spraying device for a mixture of substances (in a frontal plane). the device consists of a trolley (1), a chemical reservoir (2), a spray system unit (3), an air filter (4), a protective grille (5), a crane (6) and a mix generator (7). The trolley (1) consists of handles, wheels, housing and corresponding fasteners. With such a trolley (1), the disinfection unit becomes mobile and easy to use, and can be easily operated by one person. The capacity of the chemical reservoir (2) is large enough (up to 55 liters or even more). The chemicals in the chemical reservoir (2) are in liquid form or / and can be mixed with water or with another solvent in the appropriate ratio. The chemical reservoir (2) also includes at least two cranes (6) with corresponding tubes, one for fluid access to the nozzle assembly (3), and the other for creating and maintaining pressure in the chemical reservoir (2). The crane (6) can be more, for example, 4, 6 and so on. Their quantity depends on the design of the mix generator (7). The mix generator (7) is attached to the trolley (1) and connected to the chemical reservoir (2) by tubing. Its purpose is to mix air and chemicals and spray this mixture into the environment. The mix generator (7) consists of a spray system unit (3), an air filter (4), and a protective grille (5). Protective gratings (5) adapted to the nozzle system unit (3) perform a filter function and protect the mix generator (7) from larger dimensional garbage and other objects whose entry into the interior of the mix generator (7) is undesirable. There is also at least one air filter (4) attached to the body of the spray system unit (3) through which the outer air enters the interior of the mix generator in its middle part. There may be more air filters (4). The spray system node (3) for spraying the prepared mixture into the environment consists of a relatively thick double wall between which the air gap is located; such a construction of the spray node (3) effectively inhibits sound waves, i. reduces the noise level.

FIG. Figure 2 shows a general scheme (from the profile) of a spraying device for a mixture of chemicals. There are a few more structural elements in this scheme that make up the structure of the disinfectant. It shows the control panel (8) attached to the body of the spray system unit (3) and the motors (9). The control panel (8) is designed to control the electronic part of the system. The rotating motor (9) inside the spray system unit (3) mixes the air with the chemicals. It may be one, and there may be more of such engines (9), for example: 2. If one engine (9) fails, 6 can work with another, as well as working with several engines can improve the system. spray characteristics (standard power of one engine is 2 kW). The control panel (8) is for controlling the electrical part of the unit: it is possible to turn on / off the whole system or switch on / off the engines.

FIG. Figure 3 shows a general scheme of the body of a mixture of chemical spraying agents (frontal plane). It details the parts of the spray system unit (3): the engine (9) and the mixer (10). The purpose of the motor (9) is to create an air trap, i. Pull the air through the protective grille (5) and through the air filter (4) and push it toward the chemical blowing agent block. The air filter (4) reduces the resistance of the entire spray system unit (3) in terms of air flow permeability. The air filter (4) employs a special knit fabric that serves much longer than the parallax used in many other similar devices. The substances contained in the reservoir (2) fall into tubes from the chemical reservoir (2) to the part of the system between the motors (9) and the mixer (10). Here, chemicals mix with a strong airflow and form a mixture of chemicals. The purpose of the mixer hoppers (10) attached to the respective motors (9) is to collect, compact and direct the flow of the mixture towards the spray system. There may be at least one such collector, but there may be several. Blend collectors (10) and motors (9) are positioned so as to minimize air vortexes that increase resistance to blend flow.

Appropriate measurements have been made to determine the optimum option for the system to achieve optimum performance - with four cranes (6), two engines (9) and two (10).

FIG. Figure 4 shows a scheme of a chemical mixer. The mixer (10) consists of auxiliary hopper elements (11), an air turbocharger (12), a mixture of chemicals (13) and an air collector (14). The elements of the mixer hopper (11) are corresponding cylindrical structural elements for directing the flow of the mixture towards the turbocharger (12). The turbocharger (12) installed inside the mixer (10) directs the flow of the mixture towards the spraying unit (13). The task of the whole mixer (10) is to collect and direct the flow of the mixture through the air turbocharger (12) as far as possible towards the mixing unit (13) of the mixture. The residual pressure generated in the chamber near the mixing unit (13) is directed to the chemical reservoir 7 (2) using an air collector (14). Such a design has a positive side effect, as there is no need to worry about the pressure exerting the fluid from the chemical reservoir (2). In this way, the following circulation circuit is formed: chemical reservoir (2), nozzle (3), mixer (10), air collector (14) and again chemical reservoir (2). Such a circular circuit ensures constant pressure in the chemical reservoir (2), which displaces chemicals from the chemical reservoir (2).

FIG. Fig. 5 is a schematic diagram of the assembly of a mixture of chemical substances (13). The spraying unit (13) consists of a nozzle of the mixer (10) which sprays the prepared mixture into the environment. The spraying unit (13) comprises: a fluid supply component (15), a rear air converter flange (16), an air current converter (17), a front air converter flange (18), and a nozzle body (19). All the details (15,16,17,18,19) are assembled and compressed successively as shown in FIG. 5. The fluid supply component (15), which performs the mix acceptance function, is in the form of a cut cone (in the projection is a trapezoidal shape). Such a liquid supply form (15) is very effective in spreading the flow of the mixture from side to side. The star-shaped end-flange of the air converter (16), pressed against the fluid supply part (15), further spreads that flow. Outside the flange of the rear air converter (16), the droplets of the mixture enter the air flow converter (17), respectively pressed against the flange (18) of the front air converter, which sprays the mixture into the environment. The airflow converter (17) has a large system of blades (20) which, when passing through the flow of the mixture, spill out the chemical spraying unit (13) at high speed and, by directing towards the exit, compacts it. The degree of roll-out depends on the flow pressure, and the high-speed rotating mixing unit (13) performs the function of the pump. Therefore, the flow of the mixture passing through the nozzle system (3) has almost no resistance and is sprayed into the environment at maximum speed. The front flange of the air converter on one surface is heavily compressed to the air current converter (17), and the other surface to the nozzle body (19), which envelops the entire system of the spray unit (13). In the construction of such a blasting unit (13), a negative fluid dripping effect is avoided and a highly accurate flow direction of the blend is determined. This makes it easy, safe, fast, reliable and efficient to disinfect hard-to-reach, even high-space areas.
