Изобретение относитс к устройствам дл вибрационного сортировани волокнистых суспензий и может быть ис пользовано в целлюлозно-бумажной промышленности.The invention relates to devices for the vibratory sorting of fiber suspensions and can be used in the pulp and paper industry.

Известна вибрационна сортировка, включающа вибролоток, прикрепленный к полым опорным балкам, установленным на амортизаторах, и вибратор лотка 1 .A vibration sorting is known, including a vibrating channel attached to hollow support beams mounted on shock absorbers and a vibrator of tray 1.

Недостатком известной вибрационной сортировки вл етс мала надежность .A disadvantage of the known vibration sorting is low reliability.

Цель изобретени - повышение надежности конструкции.The purpose of the invention is to increase the reliability of the design.

Цель достигаетс тем, что в вибрационной сортировке, включающей вибролоток, прикрепленный к полым опорным балкам, установленным на амортизаторах, и вибратор лотка, последний размещен в полости одной из опорных балок, причем опорна балка, в которой размещен вибратор, имеет монтажные окна с накладками.The goal is achieved by the fact that in vibration sorting, including a vibrating channel attached to hollow support beams mounted on shock absorbers, and a tray vibrator, the latter is placed in the cavity of one of the support beams, the support beam in which the vibrator is placed has mounting windows with plates.

Размещение вибратора в полости опорной балки позвол ет отказатьс от специальных дл него опорных элемен- тов, повысив тем самым надежность конструкции. При этом опорна балка служит также защитным кожухом вибратора , т.е. совмещает функции несущего элемента вибролотка, вибратора и защитного элемента вибратора. Кроме того, при размещении вибратора Placing the vibrator in the cavity of the support beam allows you to refuse special supporting elements for it, thereby increasing the reliability of the design. In this case the support beam also serves as the protective cover of the vibrator It combines the functions of the vibrating channel carrier, the vibrator and the protective element of the vibrator. In addition, when placing the vibrator

10 в полости опорной балки обеспечиваетс смещение точки приложени возмущающего воздействи от центра масс системы, тем самым повышаетс эффективность сортировани .10, in the cavity of the support beam, the point of application of the disturbing action is shifted from the center of mass of the system, thereby increasing the sorting efficiency.

Claims

Vibration sorting includes a vibratory channel 1, fixed to hollow support beams 3 and 4 supported by 9 shock absorbers 5 mounted on a foundation by means of side walls 2. In the cavity of the front support beam 3, a vibrator 7i, for example, of an eccentric type, is installed on the platform 6 by means of a flexible shaft 8 passed through the support beam 3 connected to the electric motor 9 mounted on the foundation. In the support beam 3, in the zone of the vibrator 7, there are mounting windows 10 provided with plates 11 fixed to the beam 3, for example, with the help of bolts. Vibration sorting works in the following way. The fiber suspension to be screened is fed to the vibrating tray 1 brought into oscillatory motion by the vibrator 1 placed in the support beam 3. As you move along the vibrating channel 1, the conditioned fraction of the suspension passes through the perforation holes of the vibrating screen 1, and the waste from microdiscussion is transported along the vibrating channel 1 and discarded from it. At the same time, due to the placement of the vibrator 7 with an offset from the center of mass of the oscillating system, the vertical component of the vibration of the vibrating channel 1 on the side of the suspension inlet is maximum, decreasing in the direction of waste exit, which improves the efficiency of sorting the fibrous suspension. Execution of mounting windows 10 provided with plates 11 in the support beam 3 facilitates installation and maintenance of the vibrator 7. The invention improves the reliability of the vibrating screen design, reduces its intensity and improves the sorting efficiency of the fiber suspensions. Claim 1. Vibration sorting, which includes a vibratory channel attached to hollow support beams mounted on shock absorbers and a tray vibrator, characterized in that, in order to increase the reliability of the design, the vibrator is placed in the cavity of one of the support beams.

2. Sorting according to claim 1, that is, that the support beam in which the vibrator is placed has mounting windows with plates. Sources of information taken into account in the examination 1.
