(54) VIBRATION DEVICE

one

The invention relates to the design of devices for the regeneration of liquid filters and can be used, for example, in the coal industry in wastewater treatment plants.

A vibration device for regenerating liquid filters is known, which includes a vibrator and a vibrating head connected to it, which is made up of one or more check valves consisting of a rim, spokes, elastic plates and a central part. The holes in the head are closed with elastic plates that are rigidly mounted in the recess of the central part of the head. The plates are pressed to the surface of the spokes and the rim by the action of elastic forces11. In filters with such a vibration device, the filter septum is fixed on the shaft, which is mounted in the center of the filter. As the filter septum in the fluid cleaning section clogs, it is moved by a rotation mechanism to the regeneration section.

However, in the process of cleaning the liquid, only part of the filter partition is involved, which reduces the filter performance.

The purpose of the invention is to improve the regeneration of the filters and increase their productivity by increasing the pressure of the liquid on the filter element and continuous removal of the filtrate.

The goal is achieved by the fact that the vibrating head is made in the form of a piston with a central channel and is equipped with a rigid solid plate located parcel piston opposite to the central channel.

The drawing shows a longitudinal section of a vibrating device, a general view.

The vibrating device consists of a vibrator (not shown), a vibrating head 1 in the form of a cylindrical piston with a central through channel 2 and a rigid splash plate 3 installed with a gap. The vibrating head is located above the whole

5 filter septum 4.

The vibrating device works as follows.

Claims (2)

the vibrator vibrates the vibrating head with a frequency of 50 Hz and an amplitude of 2 mm. The rigid solid plate is fixed at a distance of 3 mm from the piston. When the vibrating head moves in the direction of the filter septum 4, a part of the liquid passes from the section of the purified liquid to the inlet section of the initial liquid, while it beats the sediment from the opposite side of the filter septum, and the other part of the liquid rushes into the gap between the plate 3 and the piston and enters central channel 2. Thus., The process of supplying purified water from the filter does not stop, although the filtering process is suspended at the time of regeneration of the filter septum. When the vibrating head moves back, the filtering process is resumed. The purified liquid enters the section where the vibrating head is located and then through the central opening to the drain. The design of the proposed vibration head allows the regeneration of the filter partition and the opening of the liquid in one section, which improves the filter performance. The absence of the washing section and the rotation mechanism associated with the mixing of the filter septum simplifies the design of the filter. Vibration device for regenerating liquid filters, including a vibrator and a vibrating head connected to it, characterized in that, in order to improve the regeneration of filters and increase their performance by increasing the pressure of the liquid on the filter element and continuous removal of the filtrate, the vibrating head is made a piston with a central channel and is equipped with a rigid solid plate located parallel to the piston opposite the central channel.
