Изобретение касаетс конструкции электростатического пылеулавливающего устройства, которое может быть использовано/в частности в текстиль- j ной промышленности дл улавливани волокнистой пыли. The invention relates to the construction of an electrostatic dust collecting device that can be used (in particular in the textile industry) for trapping fiber dust.

Известно электростатическое пылеулавливающее устройство, содержащее цилиндр, установленный с возможностью Q вращени и выполненный из диэлектрика/ и щетку, соприкасающуюс с поверхностью цилиндра и.образувдую с ним трибоэлектрическую пару И An electrostatic dust collecting device is known, comprising a cylinder mounted with Q rotation and made from a dielectric / and a brush in contact with the surface of the cylinder and forming a triboelectric pair I

Известное устройство имеет следующие недостатки.The known device has the following disadvantages.

Это вызывает искажение свойств трибоэлектрической пары в сторону уменьшени уровн электризации. При очистке поверхности цилиндра от соб- 30During the processing of fibrous materials, dust is generated that is polluted with oil and other impurities, due to which 25 the surface of the cylinder is oily. This causes the distortion of the properties of the triboelectric pair to a decrease in the level of electrification. When cleaning the surface of the cylinder from its own

На уровень электризации оказывает вли ние и влажность окружающей среды.This dust does not always ensure complete removal of dust from the surface during one revolution of the cylinder. Leaving the dust contaminates the brush, which also leads to a decrease in electrization. The level of electrification is influenced by the humidity of the environment.

Все это ведет к недостаточно полному удалению пыли с поверхности цилиндра и снижает эффективность работы устройства.All this leads to insufficient removal of dust from the surface of the cylinder and reduces the efficiency of the device.

Целью изобретени вл етс повышение эффективности удалени пыли о поверхности цилиндра путем обеспечени сохранени свойств трибоэлектрическойThe aim of the invention is to increase the efficiency of dust removal on the surface of the cylinder by ensuring the preservation of the properties of the triboelectric

С этой целью щетка расположена внутри цилиндра, причем полость цилиндра выполнена герметизированной, а внутри полости размещено влагопоглощающее средство.To this end, the brush is located inside the cylinder, the cylinder cavity being sealed, and a desiccant is placed inside the cavity.

На чертеже изображено описываемое устройство в разрезе.The drawing shows the described device in section.

Claims

The device contains a cylinder 1 and a brush 2 located inside the cylinder and. contiguous with its inner surface. Brush 2 and cylinder 1 form a triboelectric pair. The cylinder 1 by means of washers 3 and 4, bearings 5 and b is mounted on a fixed axle 7 and is driven at a time from the pulley 8. Brush 2 is fixed on axle 7. Epiploons 9 provide for gelation of the cavity of cylinder 1, into which is placed the moisture-absorbing means 10, for example silica gel. The device works as follows 5a; ™ - - .- .-. - when the cylinder 1 rotates, the brush 2 is tritted about eio inner altogether, as a result of which a charge is generated, together with a field surrounding the cylinder and space. Dust is attracted to: the outer surface of the cylinder. The arrangement of the brush inside the cylinder eliminates the influence of the state of the outer surface of the cylinder on the magnitude of the generated charge and creates more favorable conditions for the mechanized removal of collected dust from the surface of the cylinder. Claims. An electrostatic dust removal device comprising a cylinder mounted rotatably and made of a dielectric, and a brush in contact with the surface of the cylinder and forming a triboelectric pair with it, in order to increase the efficiency of removing dust from the surface of the cylinder by ensuring the preservation of properties triboelectric pair, the brush is located inside the cylinder, and the cylinder cavity is made sealed, and inside the cavity is placed a moisture device.
