The ANTICOR machine is designed for cleaning coatings of various products and materials from paints, varnishes, enamels, rust, soot, etc. The configuration of the surface to be cleaned can have a variety of shapes.
The unit also allows after readjustment of its operation mode according to the temperature of combustion products at the outlet of the gas generator (depending on the type of applied coating) to apply coatings of various metals: zinc or a mixture of zinc and aluminum.
The unit consists of a gas generator equipped with fuel component supply lines, an ejector and an abrasive particle gas pedal, as well as fuel component supply systems into the gas generator with shut-off valves. In addition to the air supply system to the gas generator (excluding the compressor), the equipment set also includes the fuel supply system, as well as the abrasive material and powder supply system.
The fuel components of the apparatus are kerosene and air. The combustion products of the fuel are fed into the jet of combustion products:
- when cleaning surfaces - abrasive material of different fractional composition by the size of abrasive particles (from 50 to 1000 microns and more);
- when applying coatings on the cleaned surface - zinc powder or a mixture of zinc and aluminum.
Fuel (kerosene) is supplied to the gas generator by displacement method.
Air is supplied to the gas generator by a compressor providing the specified parameters. To ignite the fuel components, an electric spark plug (automobile) is provided.
The abrasive material or powder of the applied metal coating is in a special consumable container at atmospheric pressure and is fed to the inlet of the gas-dynamic particle gas pedal docked with the gas generator of the unit by means of ejection created by the flow of combustion products at the outlet of the nozzle of the gas generator.
The gas generator consists of two parts - a prechamber and a combustion chamber.
In the pre-chamber with the help of the installed electric spark plug the fuel components are ignited, they are intensively mixed and the mixture prepared in this way enters the combustion chamber of the gas generator, where the combustion of kerosene is completed in the air flow, providing the specified parameters of the working body at the inlet of the ejector. With the help of the ejector the necessary pressure difference is created between the tank used for supplying the abrasive material or the tank used for supplying the powder of the metal to be sprayed and the ejector, as a result of which the air-abrasive or air-powder mixture starts to flow into the ejector.
In the gas pedal the particles of abrasive or metal powder are accelerated by the flow of combustion products, providing at the ejector outlet a high-speed two-phase jet of the required density and range.
The high efficiency of the equipment for cleaning of contaminated surfaces is 2-3 times higher than a similar air consumption sandblaster operating on cold air. This result is achieved due to the combined effect on the treated surface of high-temperature gas flow (combustion products of fuel kerosene + air) and high speeds of abrasive material (particle acceleration is carried out by supersonic gas flow).
We provide a series of mobile units differing in mass flow rate from 1 to 5 cubic meters/min.
The variety of manufactured equipment is conditioned by the tasks set by end users.
For small volumes of work, equipment with lower capacity is used, and for large volumes, respectively, more powerful equipment is used.
