Claims (6)

1. Способ очистки фильтрующей поверхности (2, 3) фильтрующей среды в вакуумной сушилке, отличающийся тем, что для определения поверхности, подлежащей очистке, отделенной от пространства, заполненного суспензией, содержащей твердое вещество, подлежащее фильтрованию, чистящий узел (7) перемещают посредством перемещающихся элементов (10) для создания контакта между определяющей поверхностью и поверхностью (4) чистящего узла (7) и для образования по существу замкнутого пространства между поверхностью, подлежащей очистке, и чистящим узлом (7), при этом в процессе очистки используют ультразвук (6), а в замкнутое пространство вводят очищающую жидкость (8) для осуществления очистки.1. The method of cleaning the filter surface (2, 3) of the filter medium in a vacuum dryer, characterized in that to determine the surface to be cleaned, separated from the space filled with the suspension containing the solid substance to be filtered, the cleaning unit (7) is moved by means of moving elements (10) for creating contact between the determining surface and the surface (4) of the cleaning unit (7) and for forming a substantially enclosed space between the surface to be cleaned and the cleaning unit (7), when In the process of cleaning, ultrasound is used (6), and a cleaning liquid (8) is introduced into the confined space to carry out the cleaning. 2. Способ по п.1, отличающийся тем, что ультразвуковые лучи сфокусированы на поверхности, подлежащей очистке. 2. The method according to claim 1, characterized in that the ultrasonic rays are focused on the surface to be cleaned. 3. Устройство для реализации способа по п.1, отличающееся тем, что для определения поверхности, подлежащей очистке, и для подвода очищающей жидкости чистящий узел (7), снабженный, по меньшей мере, одним источником (6) ультразвуковых колебаний, установлен на поверхности (2, 3), подлежащей очистке, для создания по существу замкнутой системы, которая отделена от пространства, заполненного суспензией, содержащей твердое вещество, подлежащее фильтрованию. 3. A device for implementing the method according to claim 1, characterized in that for determining the surface to be cleaned and for supplying the cleaning fluid, the cleaning unit (7), provided with at least one source (6) of ultrasonic vibrations, is mounted on the surface (2, 3) to be cleaned to create a substantially closed system that is separated from the space filled with the suspension containing the solid to be filtered. 4. Устройство по п. 3, отличающееся тем, что чистящий узел (7), по меньшей мере, в части, находящейся в контакте с поверхностью, подлежащей очистке, выполнен из упругого материала (4). 4. The device according to p. 3, characterized in that the cleaning unit (7), at least in the part in contact with the surface to be cleaned, is made of elastic material (4). 5. Устройство по п. 3 или 4, отличающееся тем, что источник (6) ультразвуковых колебаний установлен таким образом, что лучи, излучаемые источником (6) ультразвуковых колебаний, сфокусированы на поверхности (2, 3), подлежащей очистке. 5. The device according to p. 3 or 4, characterized in that the source (6) of ultrasonic vibrations is installed so that the rays emitted by the source (6) of ultrasonic vibrations are focused on the surface (2, 3) to be cleaned. 6. Устройство по одному из пп. 3-5, отличающееся тем, что расстояние между источником (6) ультразвуковых колебаний и поверхностью (2, 3), подлежащей очистке, регулируется. 6. The device according to one of paragraphs. 3-5, characterized in that the distance between the source (6) of ultrasonic vibrations and the surface (2, 3) to be cleaned is adjustable.
