DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to apparatus intended for cleaning and prevention of soiling, by employing vibration of the surfaces to be cleaned, and more particularly it relates to an apparatus for vibratory cleaning the surface of an article from foreign matter.
PRIOR ART
There is known an apparatus (SU, A, 213589) for removing ice from a casing or skin (of a vessel, aircraft, etc.), comprising an exciter of mechanical pulses which, for the purpose of directly exciting strain in the skin to be cleaned while minimizing the hazard of its being damaged, comprises a chamber filled with a non-conducting (dielectric) fluid, having electrodes mounted therein, connected to an electric discharge current source, the walls of this chamber or at least a part of these walls being the very skin to be cleaned. However, this apparatus cannot be used for cleaning surfaces made of materials with low electric conductivity, such as surfaces made of stainless steel, e.g. bins, hoppers, cyclenes, drying chambers, pneumatic transport lines, air ducts, etc., on account of the pulsed magnetic field penetrating the surface being cleaned. Moreover, the described apparatus has been found to provide inadequate efficiency of the cleaning of a surface.
There is further known an apparatus for vibratory cleaning the surface of an article from foreign matter (SU, A, 528962), comprising at least one exciter of mechanical pulses, including an electromagnetic inductor and a plate made of an electrically conductive material, arranged between the electromagnetic indicator and the surface to be cleaned. The electromagnetic inductor is connected to a source of pulsed electric current. This known apparatus for vibratory cleaning the surface of an article from foreign matter further comprises a vibration-transmitting member. This apparatus offers a relatively low efficiency factor, on account of the existence of a gap between the plate and the electromagnetic inductor, as this gap hinders the interaction of the electromagnetic field of the electromagnetic inductor with the eddy currents induced in the plate. Moreover, this apparatus of the prior art is capable of cleaning only that portion of the surface of an article which adjoins the electromagnetic inductor, and this results in the insufficient degree of the cleaning of the surface of the article. Thus, the apparatus of the prior art does not provide the necessary efficiency of the cleaning of the article surface.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to create a device for vibratory cleaning of the surface of an article from foreign matter, which should provide for stepping up the efficiency of the operation of cleaning the surface of the article.
SOLUTION TO THE TECHNICAL PROBLEM
This invention is to provide an apparatus for vibratory cleaning the surface of an article from foreign matter, comprising at least one exciter of mechanical pulses, including an electromagnetic inductor connected to a source of pulsed electric current, and a plate made of an electrically conductive material, arranged between the electromagnetic inductor and the surface of the article to be cleaned, which apparatus, in accordance with the present invention, further comprises a frame having fixedly mounted thereon the electromagnetic inductor and the plate closely adjoining this electromagnetic inductor, and at least one striking member arranged between the frame and the surface of the article to be cleaned in the area or areas of the most probable location of the foreign matter, the striking member being fixedly mounted on the frame.
It is expedient that the striking member in the apparatus for vibratory cleaning the surface of an article from foreign matter should be in the form of a rigid element.
It is further expedient that the apparatus for vibratory cleaning the surface of an article from foreign matter should have at least one striking member in the form of an electromagnetic inductor connected to an auxiliary source of pulsed electric current, with a plate clo
