Description

TECHNICAL FIELD

The present invention relates to disinfectants, in particular electric aerosol spray disinfectors, which are used for spraying chemicals and for disinfecting the respective premises.

TECHNICAL LEVEL

The world has long invented a sprayer for spraying chemicals in gardens, gardens, and indoors, but over time and as new demands arise, new designs with new features and distinctive designs have been developed.

Known Japanese patent no. JP6219904, published April 1994. August 9 This patent discloses an ethanol-filled reservoir consisting of a plastic reservoir housing, an ethanol serving disinfection system, an inlet at its upper end, a jet-type air pump that can spray ethanol from the nozzle at the touch of a button. Although easy to use, this disinfectant is small in size and designed to spray only a very small area / volume. To operate the sprayer, press and hold the button. However, this is a single-use device because the ethanol contained in said plastic reservoir runs out and the possibility of refilling with a new portion of ethanol is not anticipated by the design.

Also known as Japanese patent no. JP7008237, published May 1995. January 13 It describes a fast-acting system for disinfecting and chilling food. Foods on the conveyor are initially sprayed with water enriched with ozone and then dried with a sterile air stream. This type of conveyor is housed in a semi-enclosed chamber, i.e. the chamber has only inlet and outlet openings: on the one hand, the food is conveyed to the processing chamber and on the other hand, after processing, is diverted for further operations, such as packing. However, such a disinfection system is not mobile and is intended to disinfect food only in a small area.

Known French patent no. 609603358, Published 1997. March 29 This patent describes a method comprising a spray device and a spray material. The method is unique in that in the above-mentioned device the disinfectant is mixed with the washing liquid and the sprayer not only sprays the chemicals but also is continuously washed with the washing liquid, i.e. not clogged. This patent also describes a spray device. This sprayer is mobile and, compared to the above-mentioned counterparts, can spray over a larger area, but it is not intended for disinfecting the premises but for items placed on a special base under the sprayer.

U.S. Pat. VV02008147866, Published 2008. December 4th This patent describes a method and apparatus for generating an ozone bubble. It is a clamshell stationary unit with nozzles mounted inside, one for spraying water, one for ozone and the other for compressed gas. All of these sprinklers are pointing at each other, and during operation, water, ozone and pressurized gases mix. This creates a balloon which, depending on the nozzle layout and orientation, can be directed outward in a certain direction / angle. This type of device is designed to disinfect a small room / room. The bubble created by such a device rises up quite slowly, the particles cool down quite quickly and descend downwards.

The closest to the prior art is Japanese patent no. JP2006095345, published June 2006 April 13 This patent describes a spraying apparatus for spraying indoors, gardens, hedges, and the like. The unit itself is compact, mobile (on wheels) and can spray chemical at any desired angle. However, this unit is only convenient when it comes to spraying a small space, area, or the like, and for large areas, large volumes, and relatively tall areas, this type of unit is not suitable.

THE SUBSTANCE OF THE INVENTION

The object of the present invention is a special construction lightweight (about 40 kg), mobile (on wheels), spraying device powered by a single-phase standard mains (220 V) capable of spraying relatively large amounts of chemicals (up to 120 liters / hour) with the flow of the mixture of chemicals can reach up to 60 m in the horizontal direction. This unit can be used for disinfection of large areas, tall rooms and large cubic (up to 8800 m ³ / h) areas, such as livestock or poultry farms, large warehouses, large cubicles greenhouses, hotels, food industry facilities, other large offices .

An essential feature of the present invention is that the relatively high chemical spray volume is achieved not by increasing the electrical power of the device (conversely, only a standard single-phase 220V power network is used), but by the internal structural elements of the device Resistance to mixture flow in all air / chemical mixture flow inlet / outlet / spray systems / parts.

PREFERRED EMBODIMENTS

It is known that various forms and types of chemical spraying equipment are common in the world. In a general sense, this type of equipment has a wide range of applications: chemical spraying in gardens, gardens, livestock complexes, poultry farms, warehouses, greenhouses, hospitals, hotels and other facilities. The chemicals can be various: to disinfect a particular space or to give it certain properties, eg aromatic. One of the most important parameters of all similar devices of this type is the spray rate of the prepared mixture, which usually does not exceed 8-10 liters per hour. An essential feature of the present invention is that it can spray up to 120 liters of chemical mixture per hour. At the same time, the unit is mobile, relatively light (only about 40 kg without chemicals), easy to operate (can be easily operated by one person). To increase the rate at which chemicals are sprayed, technologists typically increase the electrical power of the device, but then a simple single-phase (220 V) power grid is not enough and a much more dangerous two- or three-phase (380 V) power source is used. However, increasing the electrical capacity of this type of device does not solve the problem, as it then significantly increases the resistance force (impedance) that occurs along the flow path of the chemical mixture. This can cause problems with system interference and burnout of electronic components.

The device of the present invention is not only capable of spraying a much larger amount (about 10 times) of the chemical mixture at the same time, is powered by a standard single-phase mains (220 V), but also has a maximum reaches up to 60 meters. These features are provided by the internal construction of the unit, which consists of a set of specially designed and mutually adapted / coordinated structural elements. This set of structural elements provides a low level of resistance as the mixture of chemicals is carried along the entire design path of the unit: from the start (chemical reservoir) to the moment the mixture is sprayed outwards.

FIG. Figure 1 is a schematic diagram (frontal plane) of a chemical mixture spray device. the unit consists of a trolley (1), a chemical reservoir (2), a spray system unit (3), an air filter (4), a guard grille (5), a crane (6) and a mixture generator (7). The trolley (1) consists of handles, wheels, housing and corresponding fasteners. With such a wheelchair (1), the disinfectant unit becomes mobile and user-friendly and can be easily operated by one person. The chemical tank (2) has a high capacity (up to 55 liters or more). The chemicals contained in the chemical reservoir (2) are in liquid form or / and may be mixed with water or other solvent in appropriate proportions. The chemical reservoir (2) also has at least two taps (6) with corresponding tubing, one for receiving fluid into the spray system assembly (3) and the other for forming and maintaining pressure in the chemical reservoir (2). There may be more cranes (6), eg 4, 6 and so on. Their amount depends on the design of the mixture generator (7). The mixture generator (7) is attached to the trolley (1) and tubularly connected to the chemical reservoir (2). Its purpose is to mix air and chemicals and spray this mixture into the environment. The mixture generator (7) consists of a spray system unit (3), an air filter (4) and a protective grille (5). The guard grille (5), adapted to the spray system unit (3), serves as a filter and protects the mixture generator (7) from larger debris and other objects that are unwanted from entering the mixture generator (7) (turbine). There is also at least one air filter (4) attached to the housing of the spray system unit (3) through which the outside air enters the interior of the mixture generator in the middle portion thereof. There may be more air filters (4). The spray system assembly (3) for spraying the prepared mixture into the environment consists of a relatively thick double wall with air gap between planes; such a design of the spray system unit (3) effectively suppresses sound waves, i.e. reduces noise levels.

FIG. Fig. 2 is a schematic diagram (in profile) of a chemical mixture spray device. This diagram shows (visible) a few more structural elements that make up the disinfectant unit. It shows the control panel (8) attached to the housing of the spray system unit (3) and the motors (9). The control panel (8) is for controlling the electronic part of the system. A rotating motor (9) mounted inside the spray system assembly (3) mixes air with chemicals. It can be one, and there may be more such engines (9), for example: 2. If one engine (9) fails, it is possible to work with another, or by working with several engines at once, the system's spraying can be further improved. characteristics (standard single engine output is 2 kW). The control panel (8) is used to control the electrical part of the unit: the entire system can be switched on / off or the motors can be switched on / off.

FIG. Figure 3 is a schematic diagram (frontal plane) of a housing for a chemical mixture spray device. It contains details of the spray system unit (3): engine (9) and mixture manifolds (10). The purpose of the motor (9) is to provide an air draft, i.e. Pull air through the guard grille (5) and through the air filter (4) and push it toward the chemical mixture spray unit. The air filter (4) reduces the impedance of the entire spray system unit (3) with respect to the airflow throughput. The air filter (4) uses a special knit fabric that lasts much longer than the parallone used in many other similar devices. The chemicals contained in the reservoir (2) enter the tubing from the chemical reservoir (2) to a part of the system located between the motors (9) and the mixture collectors (10). here the chemicals are mixed with a strong air stream and a mixture of chemicals is formed. The purpose of the mixer collectors (10) secured to the respective motors (9) is to collect, compact and direct the mixture stream towards the spray system. There may be at least one, or several, of such mixer collectors. The mixer collectors (10) and motors (9) are arranged to minimize air vortices that increase the resistance to the mixture flow.

Appropriate measurements have been made to determine the optimum system where the system achieves the optimum performance of four cranes (6), two engines (9), and two mixer collectors (10).

FIG. Figure 4 is a schematic diagram of a mixture of chemical substances. The mixing hopper (10) consists of auxiliary mixing hopper elements (11), an air turbocharger (12), a chemical mixture injection unit (13), and an air manifold (14). The manifold elements (11) are respective cylindrical structural members for directing the mixture flow towards the turbocharger (12). A turbocharger (12) mounted inside the mixing hopper (10) directs the flow of the mix toward the spray unit (13). The task of the whole mixture collector (10) is to collect and direct the mixture flow as best as possible through the air turbocharger (12) towards the mixture injection unit (13). The residual pressure exerted in the chamber immediately adjacent to the mixture spray unit (13) is directed to the chemical reservoir (2) via an air manifold (14). Such a design has a positive side effect, since there is no need to worry about creating pressure to expel the liquid from the chemical reservoir (2). In this way, the following circuit is formed: chemical reservoir (2), spray system assembly (3), mixture collector (10), air manifold (14) and again chemical reservoir (2). Such a circular circuit provides constant pressure in the chemical reservoir (2), which pushes the chemicals out of the chemical reservoir (2).

FIG. Figure 5 is a schematic diagram of the assembly of a chemical mixture spray unit (13). The spray unit (13) comprises a nozzle of a mixer (10) which sprays the prepared mixture into the environment. The spray unit (13) comprises: a fluid supply member (15), a rear air converter flange (16), an air flow converter (17), a front air converter flange (18), and a nozzle body (19). All the parts (15,16,17,18,19) are assembled and pressed in series with each other as shown in Figs. 5. The fluid supply member (15), which serves to receive the mixture, is in the form of a tapered cone (trapezoidal in projection). This form of fluid supply member (15) diffuses the mixture flow sideways very efficiently. The star-shaped rear air converter flange (16) pressed against the fluid supply member (15) continues to diffuse that flow. Behind the rear air changer flange (16), the mixture droplets enter the air flow converter (17), respectively pressed against the front air changer flange (18), which sprays the mixture into the environment. The air flow converter (17) has a system of a large number of blades (20) which, at the passage of the mixture, spins the chemical spraying unit (13) at high speed and, when directed towards the outlet, compactes. This degree of spin depends on the flow pressure and the high speed spinning mixture spray unit (13) performs the function of a pump. Therefore, the mixture flow through the spray system unit (3) is almost impedance and is sprayed into the environment at maximum speed. The front flange of the air converter is pressed firmly on one face to the air flow converter (17) and on the other surface to the nozzle body (19) enclosing the entire system of the spray unit (13). This design of the mixture spraying unit (13) avoids the negative effect of liquid dripping and provides a very precise directional flow of the mixture. This allows for easy, safe, fast, secure and efficient disinfection of hard-to-reach, even high-rise areas.
