(54) УСТРОЙСТВО ДЛЯ НАРУЖНОЙ ОЧИСТКИ ТРУБЧАТЫХ ПОВЕРХНОСТЕЙ ТЕПЛООБМЕНА(54) DEVICE FOR EXTERNAL CLEANING OF TUBULAR HEAT EXCHANGE SURFACES

Изобретение относитс  к технике очистки поверхностей теплообмена от шлаковых, золовых и пылевых отложений и примен тьс  в теплоэнергетике, например котлах.This invention relates to a technique for cleaning heat exchange surfaces from slag, ash and dust deposits and is used in heat power engineering, for example, boilers.

Известны устройства дл  наружной очистки трубчатых поверхностей теплообмена, содержащие источник колебаний с вибропередающим элементом.Devices for external cleaning of the tubular heat exchange surfaces are known, which contain an oscillation source with a vibrating element.

Предлагаемое устройство отличаетс  от известных тем, что источник колебаний выполнен в виде бойка, закрепленного в подшипниках на врашаюшейс  плите, а вибропередаюший элемент - в виде прикрепленных к ударной стороне бойка пружин.The proposed device differs from the known ones in that the oscillation source is made in the form of a striker, fixed in bearings on a rotating plate, and the vibrating element is in the form of springs attached to the shock side of the striker.

Такое выполнение устройства позвол ет повысить эффективность очистки.This embodiment of the device improves the cleaning efficiency.

На чертеже схематически изображено предлагаемое устройство.The drawing schematically shows the proposed device.

Через стенку 1 котла проходит нучок трубок 2, соединенных коллектором 3, заключенным в изол цию 4. Дл  враш,ени  плиты 5 использован двигатель 6, установленный снаружи котла и соединенный посредством передачи 1 с зубчатым колесом 8, на котором закреплена плита б. Боек 9 источника колебаний установлен на плите 5 в подшипниках 10. Плита имеет подъемный штифт И. При вра1дении плиты штифт 11 пбднимает боек 9, после чего последний под действием собственного веса падает и удар ет но коллектору 3. На ударном конце бойка установлен вибропередаюший элемент в виде пружин 12.Through the wall 1 of the boiler passes the nooks of the tubes 2 connected by a collector 3 enclosed in insulation 4. For engine, plate 5 uses an engine 6 mounted outside the boiler and connected by means of gear 1 to a gear wheel 8 on which the plate b is fixed. The die 9 of the oscillation source is mounted on the plate 5 in the bearings 10. The plate has a lifting pin I. When the plate is rotated, the pin 11 pb lifts the firing pin 9, after which the latter, under the action of its own weight, falls and strikes the collector 3. At the impact end of the striker, the form of springs 12.

Ход бойка 9 можно отрегулировать таким образом, чтобы частота ударов была 2-10 раз в минуту.The stroke of the striker 9 can be adjusted so that the frequency of the blows is 2-10 times per minute.

Наиболее эффективную очистку труб можно получить при частоте колебаний 200-2000 гц.The most effective cleaning of pipes can be obtained with an oscillation frequency of 200-2000 Hz.
