(54) VIBRATION FILTER

I

The invention relates to the field of filtration, namely, to filters for cleaning KE liquids from suspensions and can be applied both in chemical technology and in industrial water supply systems to relieve water from a gigantic suspension.

A vibration filter is known, comprising a housing with nozzles, divided into two sections by a filter partition connected to a vibrodrive.

The disadvantage of the filter is that it does not automatically remove the retented suspension from under the filter septum, which leads to difficulties in operation and reduces its efficiency.

The aim of the invention is to increase the efficiency of the filter and simplify its operation. This goal is achieved by the fact that under the filter septum, coaxially with the filter housing, there is an open cylinder at the top with a pipe for feeding the initial suspension at the apex.

The drawing shows a general view of the vibration fvptra,

The filter consists of a housing 1 divided by a filter partition 2 into the upper section 3 of the filter collection and the lower section 4 of the sediment collection. The filter septum 2, made, for example, from a mesh web, is connected via a brush 5 to a vibratory actuator (not shown). Inside the lower section 4, an open cylindrical cylindrical container 6 is installed coaxially with a nozzle for supplying the initial suspension at the top of the container, which is located in the lower part of the housing 1. The container 6 divides the lower part of the filter housing into the receiving section of the 8 n sediment collection section. An annular plain is formed between the walls of the cylinder-conical container 6 and the filter housing 1. Rancy 9.

The filtrate is discharged outside the filter through a nozzle 1O. The nozzle 11 serves to remove the sediment, and the naiw of the cuttings 12 to release air from the fifter.

For flushing the filter septum

the reverse flow of the filtrate in emergency situations is the pipe 13.

An oil seal 14 is provided for passing the vibrator rod 5.

The vibration filter works in the following way.

The initial suspension through the pipe 7 enters the receiving section 8. The liquid is then 4miltered through a constantly vibrating partition 2. Part of the suspension suspended by the partition accumulates beneath it.

Within the receiving section 8, the suspended particles are influenced, on the other hand, by the hydrodynamic forces of the upstream flow of the initial suspension, directed from bottom to top, and, on the other hand, by the back pressure caused by continuous vibration of the filter septum from top to bottom.

When the filter is in operation, a mode is created in which the forces of the hydrodynamic flow of the suspension and the forces of the counterpressure are in such a state that the sedimentation of suspended particles in an open hydraulic cylinder is eliminated. In this mode of operation of the filter, the suspended particles retained by the filter septum are constantly squeezed out. as they accumulate, peri12

The coronary annular space 9, where each particle of the suspension is acted from top to bottom by the back pressure from the vibrating wall 2. In this part of the device there are no recurring currents of the initial suspension, therefore particles of the suspension fall out in section 4 of sediment collection.

From section 4, the accumulated sludge is removed through the pipe 11, and with a high content of suspension, it can be removed through this pipe continuously.
