Description

 The invention relates to the field of special agricultural equipment, namely to disinfection machines, mainly for poultry complexes.

 A number of machines and assemblies are known that provide sanitary cleaning and bactericidal treatment of premises, the design of which contains various processing methods (thermal, chemical water, ultralight). For example, thermal sanitation of premises is provided by TG-2.5 industrial heat generators. The design of the heat generator is implemented on the basis of the usual combustion principle of producing hot air. Components: fuel tank, nozzle pump, combustion chamber, diffuser, etc. At the exit of hot air from the diffuser, formalin aerosol is generated, which is supplied to the room.

Washers are also known containing automobile chassis with a tank and pump station. A pre-heated solution of water with caustic soda to a temperature of 60-80 ^o C is filled into the tank and transported to the industrial premises for sanitation.

Attempts to make a high-performance heat engine on a self-propelled chassis were manifested in the use of aircraft turbo-generator engines mounted on automobile chassis (GD Karaban and other Machines for the maintenance and repair of roads and airfields. "Engineering", M. 1975, p. 248) . A similar machine with formalin injection into the outlet pipe was made by the company "Engineering Services" (Tomsk) for poultry and livestock farms. The parameters of the heat engine: air temperature at the outlet 100-140 ^o C, productivity 70 m ³ / s of hot air, formalin consumption 2 l / s, fuel consumption 500-800 kg / h. The need for severely deficient aviation fuel, high operating costs, the need to attract highly qualified aviation specialists, as well as the inability to obtain a comprehensive effect of sanitation are the main disadvantages of this design.

 As the closest analogue of the proposed technical solution for the totality of common features adopted hydropneumatic disinfectant installation by ed. testimonial. USSR N 118590 class A 61 L2 / 18, 1959, containing a self-propelled chassis, containers for water and a disinfectant solution, a fluid heating system and its supply through a flexible hose with nozzles.

 The lack of analogues and prototype the impossibility of obtaining a comprehensive sanitary effect, which reduces the adaptability of work, leads to an increase in labor costs of agricultural production, reduces the environmental cleanliness of the product.

 The objective of the invention is to improve the quality of the disinfection of the premises by combining them, namely, using methods of washing with hot water, foam and water treatment with a chemical solution, washing containers and aggregates, thermochemical processing, which is implemented in a single autonomous machine for disinfection of agricultural production facilities.

 The problem is solved by the fact that a tracked vehicle with a diesel installation and a drive to an electric generating set is used to power the working equipment. The machine is equipped with containers for foaming agent, water and disinfectant solution, air heaters. The tanks are connected by pipelines having shutoff valves with a pump, the mixer at the inlet is connected to the pump through a reversal pressure reducer with a compressor, and at the outlet with a flexible hose.

 In FIG. 1 is a schematic diagram of a combined disinfection system; in FIG. 2 (plan view), and in FIG. 3 (side view) of the design diagram of the machine with the placement of a disinfecting system on it.

 The combined disinfecting system of the machine consists of the following subsystems, united by common nodes (Fig. 1).

 The foam system (shown in the diagram as a solid line with circles) contains a tank with a foam disinfectant solution 1, hydraulically connected through a shut-off fan 2, pump 3. The pump is connected by a pipe to the mixer 4 and then through a flexible hose 5 with a spray device 6.

 A liquid system (double solid lines) with a disinfecting solution consists of a tank 7, in which a fluid heater 8 and a thermostat 9 are mounted, forming a closed loop for preliminary and current heating of the solution. The valve 10 at the outlet of the tank provides fluid to the pump 3, which is hydraulically connected to the mixer 4, which additionally receives compressed air to create a cavitation effect in the flexible pipe 3 and the spray device 6, which contributes to better cleanability of the structural element from dirt, feces and etc.

 The liquid system with water (solid lines) is similar to the previous one and contains a tank 15, a heater 14 with a thermostat 16, a valve 17, a pump 3, a mixer 4, a flexible hose 5, a spray device 6.

 The air system (dashed lines) contains a compressor 22, compressed air cylinders 12, a receiver 13, a valve 11 and a mixer 4. At the same time, the receiver 13 is connected by a pipe to a tank 20, which is filled with a disinfectant liquid, for example, formalin.

 The hot air system is formed by an air heater 18, into the outlet of which the valve 21 can be fed formalin from the tank 20 through the ejector 19 (lines with crosses).

 Heaters 8, 14 and 18, pump 3. Compressor 22 through the shield 24 is electrically powered by a generator 23 driven by a diesel power plant of the machine (thin lines).

 The spray device 6 is equipped with various nozzles depending on the type of work.

 In FIG. 2 and 3 show a schematic structural diagram of a machine with the placement of disinfecting technological equipment on it.

 The chassis of the machine contains a housing 25 with a diesel power plant 26 and a transmission with a drive to the front drive wheels 27. To the left of the power plant in the front of the chassis is the driver’s workstation 28, and behind it the electric generator 29 and in the central part of the chassis there is a cab with seats work crews 30.

 Technological equipment is installed in the aft part of the hull: tanks for foaming agent 1, for disinfectant solution 7, water 15, formalin 20. Heaters 8 are mounted in containers 7 and 15. Pump 3, compressor 22, mixer 4, receiver 13 and compressed air tanks 12 placed on free places. Air heaters 18 are located in the end part of the housing.

 On the sides of the machine from the outside there are two interchangeable coils with a flexible hose 5. The nodes of the system are connected by communication pipelines regulating and starting devices.

 The principle of operation of the machine, coupled with the technological cycle of sanitation of the room is as follows.

Preparatory work consists in refueling the corresponding tanks 1 and 7 with a foaming agent and a solution with bactericidal additives of a given concentration, a tank 15 with clean water and cylinders 13 with compressed air. Previously, either when the machine is moving, or at the place of work, the heaters 8 and 14 are turned on to heat the liquids to the required temperature (about 50-80 ^o C). On the access platform to the room, a flexible hose 5 is unwound and the nozzle 6 with the hose is brought into the room.

 When opening the valve 2 and turning on the pump 3, the foaming solution from the tank 1 through the mixer 4 is fed through a pipe and a flexible hose to the spray device 6 with a control valve. The foam solution is applied to the cells, conveyor, walls, etc. After applying the foam, the shut-off valve 2 is shackled and the room is eroded with the necessary technological time.

 After technological exposure of the foam solution, if necessary, the heater 8 is turned on, which additionally heats the disinfectant solution, and the thermostat 9 provides the circulation of the solution, protecting the heater from overheating. When you open the valves 10 and 11 and turn on the pump 3, the hot solution from the tank through the heater 8 and the compressed air from the cylinders 12 through the reducer 13 enters the mixer 4, where an aerosol mixture of air and disinfecting solution is formed, which through a flexible hose 5 enters the spray device 6 A jet of aerosol mixture flushes dirt and decomposed foam from cells, conveyors, walls, etc. Valves 10 and 11 are closed, pump 3 is turned off, and operation stops.

 When cleaning the premises, in order to remove residual dirt and chemically active substances to prevent corrosion, it is washed with hot water. To do this, the heater 14 is turned on for additional water heating, the pump 3 is turned on, the valves 17 and 11 are opened. Hot water from the tank 15 and compressed air from the cylinders 12 through the reducer 13 enters the mixer 4. Water-air aerosol from the mixer through a flexible hose 5 enters into the spray device.

 The intensity of the jet is selected by the appropriate nozzles and the control device of the sprayer.

 If necessary, tanks 7 and 15 can be replenished with water from the central water line continuously during sanitation.

 The air stream of the premises, aerosol disinfection, as well as the heating of the room before the landing of poultry is provided by air heaters 18. Hot gases through the mixer 19, into which formalin is injected from the tank 20, is supplied to the workshop, for example, through a heater room.

 The system is powered by an electric generator, which is driven by the power plant of the machine.

An assessment of the need for a technological sanitation process for the premises using the example of a poultry farm with a volume of 6000 m ³ showed that tank refueling capacities: 200 l with a foaming agent, 30 l with formalin, 1500 l with a disinfectant solution and 1500 l with clean water are enough to complete a full cycle of work . Taking into account the metal consumption of the system, the carrying capacity of the chassis should be at least 6000 kg. Among general-purpose and special-purpose transport vehicles in terms of carrying capacity, the most rational is the use of the casing of the tracked chassis, taking into account the requirement for the smallest possible machine dimensions.

 Conducted design and layout work and preliminary assessments showed that the technical solution is feasible and can be rationally implemented using nodes and systems of convertible samples of armored vehicles.

 Improving the technological characteristics of sanitary work in poultry and other complexes is achieved due to the efficiency of work and obtaining high sanitary-technical effect. The expansion of the scope of the invention can be obtained by endowing the machine with other technological functions, for example, providing repair and recovery, emergency operations using the energy saturation of the machine and its staffing with special equipment.
