Abstract

The invention relates to filters for the continuous cleaning of liquids used in machine building and other areas of: cleaning of heavily contaminated liquids with continuous removal of sludge, and allows for improved reliability of operation. The filter contains a conveyor made in the form of an endless flexible belt supported by the driving and driven drums. The driving drum is connected to the drive 4. The regulator is made in the form of a lever 6 rotatable around axis 5 with rollers 7 resting on the upper branch of the conveyor. Axis 5 through the pressure device 9 acts on a switch 10 mounted on the housing 8. The tape of filter material is wound from a roll and laid on the upper branch of the conveyor with the possibility of interacting with the rollers 7, and its free end is discharged into the dirt collector. 3 il. with (L

Description

fig.z

The invention relates to the field of filtration and can be used in engineering and other areas of industry when cleaning heavily contaminated liquids with continuous removal of sludge.

The purpose of the invention is to increase the reliability of the filter.

FIG. 1 shows schematically a filter, a general view, at the beginning of a filtering cycle; in fig. 2 is the same at the end of the filtering cycle; FIG. 3 is a section A-A in FIG. 2

The filter for continuous cleaning of fluid contains a conveyor I, made in the form of an endless flexible belt supported by lead 2 and 3 reels. Lead drum 2 is connected to the drive 4.

The regulator is made in the form of a lever 6 rotatable around axis 5 with rollers 7 supported on the upper branch of conveyor 1. Axis 5 protrudes beyond the limits of filter housing 8 and through a pressure device 9 acts on switch 10 attached to housing 8.

A filter tape 11 is wound from a roll 12, laid on the upper branch of the conveyor 1 with the ability to interact with the rollers 7, and its free end hangs down from the opposite end of the filter above the collector 13.

The filter works as follows

The filtered liquid enters the trough-shaped tank formed by the upper branch of the conveyor 1 and is filtered through a belt 11 of filter material. As the filtering material is soiled, the level of the liquid being filtered in a trough-shaped capacity of the tank rises. As the mass of the liquid in the tank increases, the load on the upper branch of the conveyor 1 increases and the latter bends downwards.

At a given fluid level, the lever 6 with the rollers 7 descends together with the bending upper branch of the conveyor 1 and with its pressure device 9 through the axis 5 acts on the switch 10, which closes the supply circuit of the drive 4 of the conveyor 1. The conveyor 1 begins to move in the direction indicated by the arrow contaminated filter material 13 and feeding clean filter material from the reel 1 2 into its place.

As the level decreases and the mass of liquid decreases, the deflection of the upper branch of the conveyor 1 decreases and the latter, together with the lever 6 and the rollers 7, lift up and return to its original position. The pressure device 9, when raised, ceases to act on the button of the switch 10, and the actuator 4 stops.
